HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co, Patent Agents,
Southampton Buildings, London, "IMPROVEMENTS IN SUPPORTS OR HOLDERS
FOR TELEPHONIC OR OTHER INSTRUMENTS" [a communication to him from abroad
by Charles William Holden, of Boston, Massachusetts, United States of America.]
This invention relates to supports, more particularly designed for telephonic
instruments, transmitters and receivers, either one or both, although they are also
applicable for microscopic and other instruments of various kinds.
The object of the said invention is to provide a support for such instruments
which shall be capable of ready and easy adjustment in position for the convenient
use of the instruments by operators.
This invention, as adapted more particularly for telephonic instruments, a
transmitter and a receiver, consists essentially.
First. Of a support constructed to carry and support both a telephonic receiver
and transmitter, and for either instrument to be swung upon its support and to be
adjusted either horizontally or vertically, or both horizontally and vertically, and
for each of such movements and adjustments to be made and secured practically
independently of all the others, whereby the instruments can be placed and held
in such positions that both can be used by the operator with the utmost convenience
and ease and from any position desired.
Second, of a support, composed of clamps or other holders, one for the
transmitter and one for the receiver, either or both doubly jointed to be swung on
separate centres in planes at an angle to each other, to separate telescoping or other
arms, either or both doubly jointed, to be swung on separate centres in planes at

page_text: an angle to each other, to a common standard or rod, or to separate standards or
rods, arranged to be adjusted as to its, or their, distance from, and otherwise to be
swung or moved in relation to, the location of the fixture to which this improved
support is attached for the telephonic instruments carried by it to be used, all
substantially as hereinafter described.
Third. Of the construction of the supports of this invention to receive, guide,
and protect the wires making the electric connections with said instruments all in
a manner to prevent their becoming entangled or twisted as the instruments are
moved and adjusted upon their respective supports and the supports otherwise
manipulated to bring the instruments into the most convenient positions for use.
Fourth of various details of construction hereinafter fully described.
In carrying the said invention into practice I provide a plate to be secured to a
table or other horizontal fixture, or to the wall of a room or other vertical fixture;
screws or other suitable means being used to properly fasten it.
There is a tubular standard rising from the plate and containing a vertical
screw-threaded tubular rod having a screw-threaded nut, which, being turned upon
the screw rod either to the right or to the left, will cause said rod to move up and
down. This screw-nut is confined against vertical movement by and between the
upper and lower bracket arms of the standard, and the screw rod is held against
turning while it is left free, from the turning of the nut, to move up and down as
the case may be, by a spline joint between it and the upper bracket. This spline
joint consists of a horizontal pin on the upper bracket and of a vertical groove in
the screw rod.
A horizontal plate or disc is fixed to the upper end of the tubular screw rod.
This fixed plate on its upper face has a circular recess or depression receiving a
circular washer of leather, or of other suitable packing material, and on this washer
rests a horizontal circular and rotating disc. This rotating disc is concentric with
the screw rod and also concentrically attached to the lower end of a vertical
tubular rod, and it is confined against said washer and said fixed plate by a ring
secured by means of screws or otherwise to the raised rim of the plate around said
washer. This ring overlaps the upper face of the rotating disc and in its face in
contact with said rotating disc, it has a circular concentric groove having a fixed
pin or abutment and also receiving a pin or abutment of the rotating disc all so
that said disc is free to be turned or rotated in either direction upon the stationary
plate of the standard but not, in either direction for a complete turn or rotation,
because of the necessary abutment of the pin of the disc against the pin of the ring
that is attached as described to the plate of the adjustable screw rod rising from
the standard. The fixed plate, rotating disc, and washer all are open at their
centre corresponding to the opening of the tubular screw rod standard and plate
and upward extending rod from the rotating disc, and by tightening or loosening
the contact of the rotating disc against said washer and fixed plate it is plain, the
ease with which the rotating disc may be turned or rotated can be regulated at
pleasure; and consequently while the same may be made to be freely adjustable yet
it can be made secure against accidental displacement.
The upward extending tubular rod attached to, and travelling around, with the
rotating disc is, at a short distance above said disc, bent and brought into a
horizontal position and this horizontal part or extension terminates at the outer
end in a vertical collar in which is fixed a vertical rod or standard extending
equally above and below said horizontal extension.
The tubular rod is also tubular in its horizontal extension and in fact for its
whole length, opening at a point to the outside of the vertical collar in which the
vertical standard rod is fixed.
This rod standard supports both a telephonic transmitter and a telephonic
receiver, either of any of the usual or suitable constructions.
The support of the transmitter and receiver by the standard is in each case
through similar mechanism, and such being the case, a description of the mechanism
making the support of one instrument obviously is sufficient.

page_text: The transmitter is connected to, and supported from, the lower end, and the
receiver is connected to, and supported from, the upper end of the rod standard,
and the connecting and supporting mechanism of each is as follows that is to say,
There are four joints, all of similar construction and a telescoping rod and a
clamp or holder, each of which parts is duplicated for each telephonic instrument
viz; transmitter and receiver. Each joint is in three separate lifts or leaves of a
circular disc shape and severally placed by their flat surfaces upon each other, with
a washer of leather or of other suitable packing material between them and all
secured together by a headed screw bolt passing concentrically through their several
thicknesses and screwing into either one of the outer lifts or discs but loosely
through the middle lift or disc which is thus made capable if not bound to the
disc at each side thereof by sufficiently screwing up the axial screw bolt, of being
turned or rotated upon said axial bolt.
The outside discs of each of said joints are locked together by a pin fastened to
one and entering loosely into a socket of the other, and located in a lug of such
disc which lugs project from the edge and one side of the discs and as a consequence
with either of said outside discs fastened or held against turning in any manner,
the other one thereof will be correspondingly held against movement, but if neither
thereof is so fastened and otherwise they are free to be turned, that is if not
bound against the sides of the middle disc by means of the centre or axial bolt or
either of them held in any other way, then they, with said axial bolt, can be
rotated turning by said bolt within the centre opening and by the inner face of
each outside disc against the opposite faces of the middle disc.
One set of the duplicate joints are secured, one to the upper end and the other to
the lower end of the rod standard, and in each case, the several discs making each
joint are horizontal and fastened to or against the ends of said standard, by entering
and securing the axial bolt of each into the same, and in fact preferably the outside
disc of each joint against the ends of said standard, is rigidly and independently
attached thereto.
The middle disc of the upper joint has an angular and radial arm connecting it
to an outer disc of the duplicate joints next in order of arrangement from the
rod standard, the middle disc of each of which joints is carried by one of the
telescopic rods.
Both telescopic rods project radially from the axis of rotation of their respective
joints and each is composed of an outer tubular rod having within it another rod,
both of which make the telescoping rod, that is a rod capable of being lengthened
and shortened either by drawing the inner one out of and forcing it into the outer
one, or by drawing the outer one off and forcing it over the inner one.
Each of the first named joints rotates in a horizontal plane and each of the
second named joints in a vertical plane and said planes of rotation are at right
angles.
One and the outer end of the inner rod of each telescoping rod carries a middle
disc radially attached to one of the duplicate joints next in order of arrangement
from the standard rod and one of the outside discs of each of said joints has a right
angular and radial arm, connecting it to the middle disc of one of the other of the
duplicate joints and the next and last in the order of arrangement from the
standard rod.
To the outside disc of each of said last named joints the farther removed from
the axis of rotation of other of the duplicate joints, is secured one of the duplicate
clamps or holders. These clamps are each of any suitable construction for instance
the one a ring, divided into two halves secured together about the body of the
receiver, and the other a bracket attached by screws to the underside of the
transmitter.
Some of the joints rotate in planes at right angles to each other; and the
rotation of some is in a plane coincident with the longitudinal axis of the telescopic
rod to which they are connected.
The pin locking together the two outside discs of each of the joints as herein

page_text: described prevents, by the abutment against it on either side of a part (to wit the
angular arm extensions or the telescopic rods attached to or forming a part of, and
moving with, the middle disc of such joints, or by its abutment against said part
of the middle disc) any of said joints from having or making a complete turn or
rotation in either direction about or upon their respective axial bolt or pintle.
The freedom with which each of the several joints may work or be worked it is
obvious can be regulated by tightening up or loosening its axial bolt or in other
words by tightening or loosening the several discs of each joint in their bearing
against each other and plainly any of the joints may be made rigid or fast at
pleasure by simply screwing up its axial bolt sufficiently therefor.
Electric wire connections are made with each of the telescopic instruments,
transmitter as usual, and in making these connections the several wires pass from
the instruments to, and through, the open end of the horizontal tubular rod, and
thence through said rod the rotating disc carrying its standard, hollow screw rod,
and base plate, to the other necessary parts to be connected.
In the improved support for telephonic instruments and attached to a table or
bench as herein particularly described, it is plain that each of the instruments is
capable of being adjusted in height or distance from the table,
And again each of the instruments is capable of being adjusted in its distance
from a given vertical plane passing from the front to the rear or passing across and
between the front and the rear of the support herein described, as it is attached to
the table or bench.
The adjustments of either telephonic instrument as hereinabove described, except
as to those made by the operation of the screw nut and the rotating disc, are
independent of, and separate and distinct from, each other, and from the variety
of the same as appears from the recital thereof, herein given, together with the
adjustments secured, from the operation of said screw nut and said rotating disc,
it is obvious that either instrument is capable of being placed in almost any
conceivable position, within given limits either as to any given vertical or
horizontal plane, or as to the other or companion instrument upon the same
support, and therefore, as a consequence, either and both instruinents can be
located for most convenient, easy and ready use and to suit the position and
condition of any operator or operators, and with the utmost ease, facility and
quickness, the advantages of all of which are obvious.
Limiting the rotations of the disc, and of the separate joints, substantially as
described, constituting with other parts, the support of this invention, prevents all
possibility of twisting or winding of the electric wires leading to, and from, the
instruments upon any part or parts of the support to an extent to injure or damage
the same, or to interfere with their proper operation at all times.
The horizontal extension and the vertical rod to which it forms such extension
and also both the upper and lower parts of the rod standard, may, each and all, or
such of them as desired, be made telescoping, the same as described for the
telescoping rods, and each arm or rod or part so telescoped may be allowed to turn
freely upon the other, or be constructed with a spline joint to prevent them from so
turning.
The washers for the working joints herein described may be dispensed with, buth
they are desirable as they enable sufficient friction to be given to the working
faces of the joints to hold the joints against accidental working and without
tightening the parts together to an extent to prevent their being easily worked.
The telescoping of the rods may be dispensed with but it is best to so make
them; the carrying arm for either instrument may be doubly jointed as described,
only at one and either end instead of at both ends; the double jointing of the
carrying arm for either instrument may be used in connection with means for
elevating and lowering their carrying arm other than the screw rod and screw
nut; the means for elevating and lowering the stand or support to wit, the screw
rod and screw nut may be used with other means of connection of the instruments
therewith; the standard may be secured to the wall of a room, or the like, in lieu

page_text: of to a table and such standard may be of other forms as for instance if it is to be
attached to a wall in the form of a bracket to be hereinafter described, arranged
to swing upon the wall, and other changes and combinations of the several parts
which have been herein described may be made inclusive and yet secure more or
less of the results aimed at by the present invention.
The bracket will be now described, that is to say, I provide a flat post or stud
attached to, and projecting at right angles horizontally from, the plate fixed to a
wall or other vertical rest. To this post one end of an open tubular arm is doubly
jointed and this arm at its other end is singly jointed to one end of another open
tubular arm which in turn at its other end is doubly jointed to the rod standard
carrying, as before described, a telephonic instrument such as a receiver and a
transmitter.
The double jointing of the tubular arm to the plate post and of the tubular arm
to the standard carrying the telephonic instruments and the single jointing of the
tubular arms to each other is by means of joints.
In each instance each joint is composed of three separate lifts or leaves of a
circular disc shape and severally placed by their flat surfaces upon each other with
a washer of leather or other suitable packing material between them and all
secured together by a headed screw-bolt passing concentrically through their
several thicknesses and screwing into either of the outer lifts or leaves, but loosely
through the middle lift, whis is thus Diade capable, if not bound to the lifts at
each side thereof by sufficiently screwing up of the axial screw bolt, of being
turned or rotated upon said axial bolt and otherwise all as before described for the
other joints. Again as before the outer lifts or leaves of each of these joints are
locked together by a pin fastened to one and entering loosely into a socket of the
other and located in a lug of one lift, and in an arm hereinafter referred to of the
other outer lift.
The said lugs and arms project from the edge and one side of the lifts and as a
consequence with either of said outer lifts fastened or held against turning in any
manner, the other one thereof, will be correspondingly held against movement but
if neither thereof is so fastened and otherwise they are free to be turned that is if
not bound against the sides of the middle lift, by means of the centre or axial bolt
or either of them held in any other way, then they with said axial bolt can be
rotated turning by said bolt within the centre opening and by the inner faces of
each outer lift against the opposite faces of the middle lift. In the case of the
joint at the wall plate the middle lift is a stud or post of said plate and the upper
outer lift of said joint connects by an arm to the middle lift of a joint which joint
is at right angles to the other joint, upon the wall plate.
The joint by one outer lift is connected by an arm in extension of the tubular
arm to one end of said tubular arm and this tubular arm by an extension at its
other end is connected to the outer lift of the three lifts making the joint between
the two tubular arms, and the said last named joint is the same in construction and
arrangement of parts as previously described for the other joints.
The middle lift of one joint is connected by an arm in extension of the tubular arm
to one end of said tubular arm and this tubular arm has an extension at its other end
and is connected by said arm or extension to the middle lift of a joint connected by one
of its outer lifts to the middle lift of another joint by an arm of one of its outer
lifts and through the horizontal projecting tubular arm, to the rod or standard to
which the receiver and the transmitter are connected as has been described.
Two joints are at right angles to each other as before stated for other joints,
between the wall plate and the tubular arm and as a consequence the planes of
rotation of the two joints of each set of double joints are at right angles to each
other.
The axial bolt of one joint at the wall plate is made tubular for the passage of
the electric wires through it, and thence through a tubular arm, to and through
another tubular arm, and to and through another. tubular arm, of rod standard to
the transmitter and receiver,

page_text: Arms preferably tubular and jointed at one end to each other, and at the other
end of each doubly jointed the one to a wall plate or equivalent plate, and the
other to a rod standard or equivalent part to which the telescopic or other
instruments are connected, constitutes in substance the bracket making a part of
the support of this invention, and in substitution of the standard and its lifting
and lowering screw rod before described.
Eyes or loops are fastened to parts of the bracket herein described, for guides
for the passage of the electric wire through the parts of the bracket as has been
herein described.
The tubular arms may be connected to each other by a double joint as has been
described for the connection of the other ends of each of said arms; and again the
connection of said arms to the wall plate and to the rod-standard, either or both,.
may be by a single joint such as the joint described for connecting the two arms
together in lieu of a double joint, and yet secure in substance the objects of this
invention, but it is preferable to join the parts as has been particularly described,
as by such jointing the greatest number of adjustments is obtainable.
An outer lift of one of the joints may be provided with an arm having thumb
screw, in position to be set against and lowered from the edge of the middle lift
of said joint and thereby enabling said joint to be fixed against and released to
movement which as is obvious in some cases might be advantageous to use.
An arm and thumb screw as above described may be applied to any of the
joints described and the application of said arm and thumb screw is to be in such
relation to the movement of the joint as only to interfere in the smallest degree
possible with the movement of the joint.
Each clamp or holder for the instruments is swivelled by a pintle in a split ring
clamped upon and around a rod by turning up its thumb screw. The swivelling
pintle has a peripheral groove receiving a set screw of the split ring that turned
up against the pintle fastens it against movement, and loosened therefrom permits
the clamp to swivel in its split ring while holding it from accidental escape.
Loosening the thumb screw sets its split ring free for it, with the instrument it
carries, to be swung around and moved along the rod, and tightening it up fastens
said ring and its instrument against movement around and along said rod.
A horizontal hinge joins the rods to the horizontal arm of the vertical tubular
rod and there is a thumb screw making its axial pintle which turned in one
direction tightens the hinge and makes it and the several arms rigid, and turned
in the other direction, loosens said hinge for the several arms to be swung around
its pintle. The vertical rod passes directly through the tubular standard and this
standard at its upper portion is radially split and exteriorly tapering and screw
threaded and provided with an external screw threaded nut.
The split portion of the standard by properly turning the screw nut over it, is
either compressed and tightly bound upon and about or loosened from the vertical
rod. This enables the said vertical rod to be adjusted and set in its height of pro-
jection from the standard as may be desired, and to ensure its being held in its
adjusted position against all possibility of accidental displacement, interlock with
it the set or thumb screw of the standard with a perforation of the series of
perforations arranged along its length. With this set-screw disengaged and the
split portion of the standard released from the vertical rod said rod is then not
only free to be raised and lowered in said standard as before stated, but also to be
rotated therein.
Electric wires properly insulated connect the instrumentss as
usual with the different circuits employed in telephonic apparatus and these several
wires pass upward through the hollow standard and tubular rod, and from thence
out through suitable openings in the horizontal arm to the instruments;
Although the present improved stand or holder or bracket has been herein
particularly described in connection with telephonic instruments it may be used
for any and all other instruments for which said stand or support may be found
avaiable, as for instance microscopic instruments or the like.

by Charles William Holden of Boston Massachusetts United States of America
This invention relates to supports more particularly designed for telephonic
instruments transmitters and receivers either one or both, although they are also
applicable for microscopic and other instruments of various kinds.
The object of the said invention is to provide a support for such instruments
which shall be capable of ready and easy adjustment in position for the convenient
use of the instruments by operators.
This invention, as adapted more particularly for telephonic instruments, a
transmitter and a receiver, consists essentially-First of a support constructed to
carry and support both a telephonic receiver and transmitter and for either
instrument to be swung upon its support and to be adjusted either horizontally
or vertically or both horizontally and vertically and for each of such movements
and adjustments to be made and secured practically independently of all the
others whereby the instruments can be placed and held in such positions that both
can be used by the operator with the utmost convenience and ease and from any
position desired. Second of a support, composed of clamps or other holders, one
for the transmitter and one for the receiver either or both doubly jointed to be
swung on separate centres in planes at an angle to each other, to separate
telescoping or other arms, either or both doubly jointed to be swung on separate

A represents a plate shewn in Figures 1, 2, 3 and 4 and 15 and 16 as secured to
a table or other horizontal fixture and in Figures 11 12, 13 and 14 as secured to
the wall of a room or other vertical fixture; screws or other suitable means being
used to properly fasten it.
C Figures 1, 2, 3 and 4 is a tubular standard rising from the plate A. and
containing a vertical screw threaded tubular rod D having a screw threaded nut E
which being turned upon the screw rod D either to the right or to the left will
cause said rod to move up and down. This screw nut E is confined against
vertical movement by and between the upper and lower bracket arms F G of the
standard C, and the screw rod D is held against turning while it is left free from
the turning of the nut to move up and down as the case may be by a spline joint
between it and the upper bracket F. This spline joint consists of a horizontal
pin a on the upper bracket F and of a vertical groove b in the screw rod D
H is a horizontal plate or disc fixed to the upper end of the tubular screw rod D.
This fixed plate H Figure 5 on its upper face has a circular recess or depression d
receiving a circular washer e of leather or of other suitable packing material, and
on this washer rests a horizontal circular and rotating disc J. This rotating disc J
is concentric with the screw rod D and also concentrically attached to the lower
end of a vertical tubular rod K and it is confined against said washer e and said
fixed plate H by a ring L secured by means of screws for otherwise to the raised
rim of the plate H around said washer. This ring L overlaps the upper face of the
rotating disc J and in its face in contact with said rotating disc it has a circular
concentric groove g having a fixed pin or abutment h and also receiving a pin or
abutment of the rotating disc J all so that said disc J is free to be turned or
rotated in either direction upon the stationary plate H of the standard C, but not,
in either direction, for a complete turn or rotation, because of the necessary
abutment of the pin k of the disc J against the pin h of the ring L that is attached
as described to the plate H of the adjustable screw rod D rising from the standard C
the fixed plate H rotating disc J and washer e all are open at their centre
corresponding to the opening of the tubular screw rod D standard C and plate A
and upward extending rod K from the rotating disc J and by tightening or
loosening the contact of the rotating disc against said washer and fixed plate it is
plain, the ease with which the rotating disc may be turned or rotated can be
regulated at pleasure; and consequently while the same may be made to be freely
adjustable yet it can be made secure against accidental displacement.
The upward extending tubular rod K attached to and travelling around with the
rotating disc J is at a short distance above said disc, bent and brought into a
horizontal position, as shewn at M and this horizontal part or extension M
terminates at the outer end in a vertical collar N in which is fixed a vertical rod
or standard O extending equally above and below said horizontal extension.
The tubular rod K is also tubular in its horizontal extension. M and in fact for

page_text: its whole length opening at to the outside of the vertical collar N in which the
vertical standard rod O is fixed as above described. This rod standard O supports
both a telephonic transmitter P and a telephonic receiver Q either of any of the
usual or suitable constructions, but in Figures 11, 12, 13 and 14, in lieu of the
connection between it and the plate A above particularly explained, it is shewn
as connected to the plate A through jointed arms D' and G making as it were
a bracket all as will be hereinafter fully described
The support of the transmitter and receiver by the standard O is in each case
through similar mechanism, and such being the case a description of the mechanism
making the support of one instrument obviously is sufficient if the proper letters
be applied to the corresponding parts of the others.
The transmitter P is connected to and supported from the lower end, and the
receiver is connected to and supported from the upper end of the rod standard O
and the connecting and supporting mechanism of each is as follows:-
-
Four joints R S T and U all of similar construction, a telescoping rod V and a
clamp or holder W each of which parts is duplicated for each telephonic instrument,
transmitter P and receiver Q.
Each joint R S T and U is in three separate lifts or leaves m n q of a circular
disc shape and severally placed by their flat surfaces upon each other with a
washer (see Figures 7 and 8 more particularly) of leather or of other suitable
packing material, between them and all secured together by a headed screw bolt t
passing concentrically through their several thicknesses and screwing into either
one of the outer lifts or discs m q but loosely through the middle lift or disc n
which is thus made capable, if not bound to the discs at each side thereof by
sufficiently screwing up the axial screw bolt, of being turned or rotated upon said
axial bolt.
The outside discs m and g of each of said joints are locked together by a pin a³
fastened to one and entering loosely into a socket b² of the other and located in a
lug d of such disc which lugs project from the edge and one side of the disc and
as a consequence with either of said outside discs fastened or held against turning
in any manner the other one thereof will be correspondingly held against movement
but if neither thereof is so fastened and otherwise they are free to be turned, that
is, if not bound against the sides of the middle disc n by means of the centre or
axial bolt tor either of them held in any other way, then they with said
axial bolt can be rotated turning by said bolt within the centre opening and
by the inner face of each outside disc against the opposite faces of the middle
disc.
The duplicate joints R are secured one to the upper end and the other to the
lower end of the rod standard O and in each case the several discs making each
joint are horizontal and fastened to or against the ends of said standard, by
entering and securing the axial bolt t of each into the same, and in fact preferably
the outside disc of each joint, against the ends of said standard is rigidly and
independently attached thereto.
The middle disc of the upper joint has an angular and radial arm e² connecting
it to an outer disc q. of the duplicate joints S next in order of arrangement from
the rod standard O, the middle disc n of each of which joints is carried by one of
the telescopic rods V.
Both telescopic rods V project radially from the axis of rotation of their respective
joints and each is composed of an outer tubular rod h² having within it another
rod 2 both of which make the telescoping rod, that is a rod capable of being
lengthened and shortened either by drawing the inner one * out of and forcing it
into the outer one h³ or by drawing the outer one h² off and forcing it over the
inner one k²
Each joint R rotates in a horizontal plane and each joint S in a vertical plane
and said planes of rotation are at right angles.
One and the outer end of the inner rod k of each telescoping rod V carries a
middle disc n radially attached to one of the duplicate joints T next in order of

page_text: arrangement from the standard rod O, and one of the outside discs m, of each of
said joints has a right angular and radial arm 12, connecting it to the middle disc n
of one of the duplicate joints U and the next and last in the order of arrangement
from the standard rod O.
To the outside disc m of each of said joints U the farther removed from the
axis of rotation of the joints T is secured one of the dupli-clamps or holders W.
These clamps are each of any suitable construction for instance the one a ring,
divided into two halves secured together about the body of the receiver Q and the
other a bracket attached by screws to the under side of the transmitter P.
Each joint T and each joint U rotate in planes at right angles to each other
and the rotation of the former is in a plane coincident with the longitudinal axis
of the telescopic rod V to which it is connected.
The pin a locking together the two outside discs of each of the joints R S T U
as herein described prevents by the abutment against it on either side of a part (to
wit the, angular arm extensions e² 12, or the telescopic rods V attached to or forming a
part of and moving with the middle disc of such joints or by its abutment against
said part of the middle disc) any of said joints from having or making a complete
turn or rotation in either direction about or upon their respective axial bolts t
The freedom with which each of the several joints R S T U may work or be
worked it is obvious can be regulated by tightening up or loosening its axial bolt t
or in other words by tightening or loosening the several discs of each joint in their
bearing against each other and plainly any of the joints may be made rigid or fast
at pleasure by simply screwing up its axial bolt sufficiently therefor.
Electric wire connections are made with each of the telescopic instruments,
transmitter P and receiver Q as usual and in making these connections the several
wires pass from the instruments to and through the open end of the horizontal
tubular rod M and thence through said rod the rotating disc J carrying its
standard C hollow screw rod D and base plate A to the other necessary parts to be
connected.
In the improved support for telephonic instruments and attached to a table or
bench as herein particularly described, it is plain that each of the instruments is
capable of being adjusted in height or distance from the table.
•
First by raising or lowering the vertical screw rod D in the standard C from
the turning of the screw nut E.
Second by swinging its telescopic rod V in a vertical direction through the
joint S of said rod V which is connected with the middle disc n of the joint R
upon the rod standard O
Third. By swinging its clamp W in a vertical direction or plane through the
joint U of said clamp which is connected with one of the outside discs m of the
joint T at the outer end of its telescopic rod V, and,
Fourth, by either lengthening or shortening its telescoping arm or rod V.
And again each of the instruments is capable of being adjusted in its distance
from a given vertical plane passing from the front to the rear or passing across
and between the front and the rear of the support herein described, as it is attached
to the table or bench in the following manner that is to say. First by rotating
the disc J upon its support H, of the screw rod D passing through standard C;
second by swinging its telescoping arm or rod V in a vertical plane or direction
through the joint S of said rod connecting it with the middle disc of the joint R
upon the rod standard O; third by swinging its telescoping arm or rod V in a
horizontal direction or plane through its joint R connecting it with the rod
standard O. Fourth, by swinging its clamp or holder W in a vertical direction or
plane through the joint T upon the outer end of its telescoping rod V.; Fifth by
swinging its clamp or holder W around upon the joint U which joint is connected
to the joint T connected to the outer end of the telescoping arm V. Sixth, by
either lengthening or shortening its telescoping arm or rod V.
The adjustments of either telephonic instrument as hereinabove described except
as to those made by the operation of the screw nut E and the rotating disc J aro

page_text: independent of and separate and distinct from each other, and from the variety of
the same as appears from the recital thereof herein given together with the
adjustments secured from the operation of each screw nut E and said rotating disc
it is obvious that either instrument is capable of being placed in almost any
conceivable position of course within given limits, either as to any given vertical
or horizontal plane, or as to the other or companion instrument upon the same
support, and therefore as a consequence either and both instruments can be located
for most convenient easy and ready use and to suit the position and condition of
any operator or operators and with the utmost ease facility and quickness the
advantages of all of which are obvious. .
Limiting the rotation of the disc J and of the separate joints R, S, T, U,
substantially as described, constituting with other parts, the support of this
invention, prevents all possibility of twisting or winding of the electric wires
leading to and from the instruments upon any part or parts of the support to
an extent to injure or damage the same, or to interfere with their proper operation
at all times.
A screw nut E for adjusting the screw rod D and operating thereon as described
together with a telephonic instrument or instruments connected to said rods is
important, in that it not only by a turning of the screw nut in the proper
direction secures the lifting and lowering of the instruments through its operation
upon said screw rod but it also holds said instruments in their so adjusted
positions without further operation of any mechanism or use of any other fastening.
device or devices.
The horizontal extension M and the vertical rod K to which it forms such
extension and also both the upper and lower parts of the rod standard O may each
and all or such of them as desired be made telescoping, the same as described
for the telescoping rods V and each arm or rod or part so telescoped may be allowed
to turn freely upon the other or be constructed with a spline joint as at m²
Figure 2 to prevent them from so turning.
It is obvious first, that the support herein described as to either instrument is
complete of itself and works the same in every respect; Second that while either
instrument can be placed at a greater or lesser distance or height from the table or
other rest to which the telephone support is secured and also can be swung about.
the vertical line of the movement or adjustment just above stated, that is the
vertical axis of the standard C, yet either instrument is also capable of being
swung around two other axes (the axes of the joints R, U,) at a distance from each
other, which axes are parallel to each other and also to but not coincident with the
axial swing and adjustment of the instrument first above stated and in addition
thereto either instrument is also capable of being swung around two other axes
(the axes of the joints S T) at a distance from and parallel to each other and at
right angles to each other and all the other axes above referred to.
Among special advantages of the telephone support of this invention in addition
to its general and other capabilities before recited it may be well to mention―
First, that the telephonic instrument and their connections when not in use can
be swung to the rear or either side of the standard C, and thus placed out of the
way; Second that the double joints of the telescoping rods at each end as described
are in the nature of universal joints and as a consequence, in whatever positions
the instruments may be placed by swinging them upon said joints and otherwise
adjusting them, a then slight movement of the joints enables the instruments to be
placed squarely to the mouth or ear, as the case may be, and without necessarily
changing the height or distance of the whole apparatus from its point of fixture to
the table wall & Third as the instruments are at the outer ends of their respective
carrying arms and jointed thereto as described when placed in position for use
there are no obstructing arms in the way of the operator, and again the instruments
can be swung and placed above the carrying arms so as to leave a clear space below
-Fourth-by a simple movement of the parts carrying the instruments the
position of the instruments can be readily changed for the receiver to be used at.

page_text: either the right or left ear of the operator and for the transmitter to be placed in
suitable relative position. The washers for the working joints herein described
may be dispensed with but they are desirable as they enable sufficient friction to
be given to the working faces of the joints to hold the joints against accidental
working, and without tightening the parts together to an extent to prevent their
being easily worked.
The telescoping of the rods may be dispensed with but it is best to so make
them; the carrying arm for either instrument may be doubly jointed as described,
only at one and either end instead of at both ends; the double jointing of the
carrying arm for either instrument may be used in connection with means for
elevating and lowering their carrying arm other than the screw rod D and screw
nut E; the means for elevating and lowering the stand or support to wit; the
screw rod D and screw nut E may be used with other means of connection of the
instruments therewith; the standard C may be secured to the wall of a room. &c.
in lieu of to a table and such standard may be of other forins, as for instance if it
is to be attached to a wall in the form of a bracket (see Figures 11 to 14 inclusive)
to be hereinafter described, arranged to swing upon the wall, and other changes
and combinations of the several parts which have been herein described so fully
may be made (see Figures 15 to 20, inclusive to be hereinafter described and yet
secure more or less of the results aimed at by the present invention.
However a telephone stand or support having all. the parts and operations and
movements specified is most desirable for manifest reasons.
The bracket just above referred to as shown in Figures 11 to 14 inclusive will
be now described-C2 C2 indicate a flat post or stud attached to and projecting at
right angles horizontally from the plate A fixed to a wall or other vertical rest.
To this post C one end of the open tubular arm D is doubly jointed and this
arm D at its other end is singly jointed to one end of the other open tubular
arm G which in turn at its other end is doubly jointed to the rod standard O,
carrying as before described a telephonic instrument such as a receiver and a
transmitter P.
The double jointing of the tubular arm D2, to the plate post C and of the
tubular arm G to the standard O carrying the telephonic instruments, and the
single jointing of the tubular arms D3 and G' to each other is by means of
joints M and M* N' and N* and F2 respectively.
In each instance each joint is composed of three separate lifts or leaves of a
circular disc shape and severally placed by their flat surfaces upon each other with
a washer of leather or other suitable packing material between them and all
secured together by a headed screw bolt passing concentrically through their
several thicknesses and screwing into either of the outer lifts or leaves, but loosely
through the middle lift, which is thus made capable, if not bound to the lifts at
each side thereof by sufficiently screwing up of the axial screw bolt, of being
turned or rotated upon said axial bolt, and otherwise all as before described for the
joints R. S. T U. Again, as before, the outer lifts or leaves of each of these joints
are locked together by a pin fastened to one, and interlocking loosely into a socket
of the other and located in a lug of one lift, and in an arm hereinafter referred to
of the other outer lift.
The said lugs and arms project from the edge and one side of the lifts, and as a
consequence with either of said outer lifts fastened or held against turning in any
manner, the other one thereof will be correspondingly held against movement, but
if neither thereof is so fastened and otherwise they are free to be turned, that is
if not bound against the sides of the middle lift, by means of the centre or axial
bolt or either of them held in any other way. then they with said axial bolt can be
rotated, turning by said bolt within the centre opening and by the inner faces of
each outer lift against the opposite faces of the middle lift. In the case of the
joint M² at the wall plate A, the middle lift is the stud or post C* of said plate, and
the upper outer lift of said joint connects by an arın to the middle lift of the
joint M* which joint M*, is at right angles to the joint M³ upon the wall plate A.

page_text: The joint M by one outer lift is connected by an arm n² in extension of the
tubular arm D2, to one end of said tubular arm D2, and this tubular arm by an
extension q, at its other end is connected to the outer lift of the three lifts making
the joint F between the two tubular arms D, G, and said last named joint F* is
the same in construction and arrangement of parts as previously described for the
other joints.
The middle lift of the joint F2 is connected by an arm in extension of the
tubular arm G to one end of said tubular arm G² and this tubular arm has an
extension at its other end and is connected by said arm or extension to the middle
lift of the joint N' connected by one of its outer lifts to the middle lift of the
joint N, by an arm of one of its outer lifts and through the horizontal projecting
tubular arm W³, to the rod or standard O, to which the receiver and the transmitter
are connected as has been described.
The joints N2, and N* are at right angles to each other as before stated for the
joints M, and M*, between the wall plate A, and the tubular arm D³, and as a
consequence the planes of rotation of the two joints of each set of double joints are
at right angles to each other.
The axial bolt of the joint M2, at wall plate A is made tubular (Figures 12,
and 13,) for the passage of the electric wires through it, and thence through the
tubular arm D³, to and through the tubular arm G and to and through the tubular
arm W³, of rod standard O, to the transmitter and receiver.
The arms D, G, preferably tubular and jointed at one end, to each other, and at
the other end of each, doubly jointed, the one D³, to a wall plate A, or equivalent
plate, and the other G2, to a rod standard O, or equivalent part to which the
telephonic or other instruments are connected constitutes in substance the bracket
making, a part of the support of this invention, and in substitution of the
standard C, and its lifting and lowering screw rod D, before described, and it is
obvious: First, that the several joints between the parts may, by properly
turning up or loosening their respective axial bolts, be made fast or rigid, or loose,
in operation to the degree required; Second, that neither of the joints can make a
complete rotation because of the abutment of the pin which connects its outer lifts
against the arm which connects a lift of said joint, either to another of said joints
next in order of arrangement or to one of the tubular arms D², G³, as the case may
be, and that, as a consequence there can be no possibility of an entanglement and
twist of the electric wires about the exposed parts of the bracket. Third, that the
double jointing of the tubular arms D³, G², together with the joint of the arms to
each other, such as herein described obviously enables the bracket to be brought
to almost any position which may be desired thus enabling even if such a bracket
is used alone, with telephonic instruments such instruments to be most easily and
readily located for convenient use by operators.
Of course with mechanism such as before described and shown as connecting the
rod standard O, to the telephonic instruments, it is plain the scope and variety of
adjustment as to position for the telephonic instruments will, with the adjustments
from the bracket herein shown and described, be greatly increased and augmented.
(Figures 11 and 12) are eyes or loops fastened to parts of the bracket
herein described, for guides for the passage of the electric wire through the parts of
the bracket as has been herein described.
The tubular arms D³, G³, may be connected to each other by a double joint, as
has been described for the connection of the other ends of each of said arms; and
again the connection of said arms to the wall plate A and to the rod standard O,
either or both may be by a single joint such as the joint F described, for
connecting the two arms D, G, together, in lieu of a double joint, and yet secure
in substance the objects of this invention, but it is preferable to join the parts as
has been particularly described as by such jointing the greatest number of
adjustments is obtainable.
In Figure 14 an outer lift of the joint M³, is shown as provided with an arm t³,
having thumb screw u², in position to be set against and loosened from the edge of

page_text: the middle lift of said joint and thereby enabling said joint to be fixed against and
released to movement, which as is obvious in some cases might be advantageous
to use.
An arm and thumb screw as above described may be applied to any of the joints
described and the application of said arm and thumb screw is to be in such relation
to the movement of the joint as only to interfere in the smallest degree possible
with the movement of the joint.
As shown in Figures 15 to 20, inclusive each clamp or holder W, for the
instruments P and Q, is swiveled by a pintle a³ in a split ring A³, clamped upon
and around a rod V, by turning up its thumb screw B³.
The swiveling pintle a³, has a peripheral groove b", receiving a set screw d³, of
the split ring A³, that turned up against the pintle as fastens it against movement,
and loosened therefrom permits the clamp W, to swivel in its split ring A5, while
holding it from accidental escape.
Loosening the thumb screw B³, sets its split ring A³ free for it with the
instrument it carries to be swung around and moved along the rod V, and
tightening it up, fastens said ring and its instrument against movement around
and along said rod V.
N³ is a horizontal hinge joining the rods V to the horizontal arm M of the
vertical tubular rod K, and C is a thumb screw making its axial pintle which,
turned in one direction, tightens the hinge and makes it and the several arms V
and M rigid, and turned in the other direction loosens said hinge for the several
arms to be swung around its pintle. The vertical rod K passes directly through
the tubular standard A, and this standard at its upper portion D is radially split
(Figure 20) and exteriorly tapering and screw threaded (Figure 16) and provided
with an external screw threaded nut E5 (Figures 15, 16 and 20).
The split portion of the standard A, by properly turning the screw-nut over it,
is either compressed and tightly bound upon and about, or loosened from the
vertical rod K. This enables said vertical rod K to be adjusted and set, in its
height of projection from the standard A, as may be desired, and to ensure its
being held in its adjusted position against all possibility of accidental displacement,
interlock with it (Figure 16) the set or thumb screw f5 of the standard A, with a
perforation go of the series of perforations arranged along its length. With this
set-screw disengaged and the split portion D³ of the standard Å, released from
the vertical rod K, said rod is then not only free to be raised and lowered in said
standard as before stated, but also to be rotated therein. Electric wires properly
insulated connect the instruments P, and Q, as usual with the different circuits
employed in telephonic apparatus and these several wires pass upward through the
hollow standard A and tubular rod K and from thence out through suitable
openings in the horizontal arm M to the instruments; h and are binding
posts or studs for guides to the wires as they lead out from the arm M to the
receiver Q.
From the description of the support shown in Figures 15 to 20 inclusive it is
plain that said support consists essentially of two horizontal arms V, V, on
carrying a telephonic receiver Q, and the other a telephonic transmitter P and of a
vertical arm K and that these arms are severally jointed together and all so that
any of them can of itself be swung independently of the others in a horizontal
plane, and that the vertical arm K, can be turned around and raised and lowered
in its standard or post A independently of its said swinging and of that of the
other arms V, V, jointed to it; and again, that, in addition to the above, in this
improved support, each instrument is swivelled to and also otherwise attached to
its supporting arm V all, so that it can be swung, around or rotated, in two planes
at right angles to each other (swinging in the one plane, around the axis of its
swivel joint a and b and in the other plane around the axis of its carrying arm V)
and also, so that it can be moved horizontally along its carrying arm and thus
placed nearer to, or further, from as the case may be, the axis of the joint or hinge
common to it and the other arms V, K, and that any of its said movements can be

page_text: made of itself and in-dependently of the others as also of the movements of the
arms upon themselves and of the raising and lowering the vertical arm K upon
and its turning within the standard A as has been above stated.
To swing the several arms V, and K horizontally upon their common joint N³ as
above described loosen said joint by properly turning its pintle or thumb screw C³
to rotate either instrument, if about the axis of its swivel joint a³, 6* loosen the
set screw d³ of said joint and if about the axis of its carrying arm V, loosen its
thumb-screw B and also with said thumb screw loosened the instrument is free to
be moved along its carrying arm; to raise or lower the vertical arm K and its
connected arms V, V, carrying the instruments and to rotate said arms in the
standard A, withdraw the set screw f' and loosen the grip of the upper split
end D of the standard A, upon said vertical arm, by properly turning the
screw-nut E³
The several parts of the support having been loosened for movement as above
described and then moved to secure the position of the instruments P, and Q,
desired are fastened and the instruments thus secured in their adjusted positions,
by tightening therefor the proper parts of the mechanism and adapted to be used
as may be desired.
Although the present inproved stand or holder or bracket has been herein
particularly described in connection with telephonic instruments and in the claims
also particularly so stated, such descriptions and claims as meant to includes any and
all other instruments for which said stand or support may be found available as for
instance microscopic instruments etc and so therefore it is not intended that this
invention either in its description or in the recital of the claims shall be limited to
telephonic instruments only.
