Improvements in Apparatus for Receiving Payments and Permitting
the Testing of Muscular Strength in Exchange for such Pay-
ments, and for other Purposes.
I, HENRY HARRIS LAKE, of the firm of Haseltine Lake, & Co., l'atent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature of
this invention to be as follows:-
as a
This invention is particularly designed for dynamometers adapted to test and
indicate the power or force exerted by the grip of a person's hand, although as
will be obvious from the description of it which follows, it is applicable to other
dynamometers, for illustration, recording weighing scales and pulling and pushing
machines, or scales, and the like. The invention more particularly pertains to the
means for holding the dynamometer against and for releasing it for action, through
an article of a predetermined weight, size or other dimensions or characteristic, such
five cent, nickel," to act as an intermediary when suitably applied. The invention
consists, in substance in the combination with a dynamometer, for illustration, one
suitable to determine the power exerted by the grip of a person's hand, of a receiving
chute or conduit for a piece of metal or equivalent material of a predetermined
weight, or size or other dimensions, as for instance a five cent. nickel" to act as an
intermediary as hereafter appears, and which chute has, in its length, two separate
metal or other suitable contacts, separately electrically connected and each and both
arranged with said intermediary in the chute and from the action thereof to make an
electric circuit through said metal contacts but at all other times to have and maintain
said electric circuit broken, and electric battery electrically connected to said electrical
contacts of said chute, a catch to engage and hold the dynamometer against and to
release it to operation, an electro-magnet in the electric circuit aforesaid, an armature
for said electro-magnet, to be operated by said magnet and thereby to release said
catch from the dynamometer but at all other times to allow said catch to remain in
its said engagement, and means operated by the dynamometer to release said inter-
mediary to be discharged from the chute and severally all otherwise constructed,
combined and arranged substantially as hereinafter described and whereby on the
insertion of an intermediary, such as a "five cent. nickel" in said chute, an electric
circuit will be established, and thereby the dynamometer released to operate and
in the operation of the dynamometer said "five cent. nickel" will be released to
be discharged from the chute at the same time breaking the electric-circuit, on
which said catch is free to return to its engagement with the dynamometer to again
hold it, and as before against action.
Again the invention consists, in the combination with the above of an alarm-bell,
a hammer for sounding said bell, an electro-magnet in an electric circuit, an
armature for said electro-magnet to be operated by said magnet and thereby to
secure through said hammer a sounding of said bell, and means in said electric
circuit by which to establish the circuit only on a given and predetermined movement
of the dynamometer.
In addition to the above, the invention consists of other constructions, combi-
nations and arrangement of the parts of the dynamometer, all substantially as
hereinafter described.
The invention comprises an upright cabinet of a rectilinear shape and having a
cabinet base, by which to stand it on the floor or other suitable support.
The cabinet contains the dynamometer mechanism of this invention and it has.an

page_text: opening and closing front door, under lock and key, and its base contains the
electric battery or batteries and also a money receiving or cash drawer or box, under
lock and key.
The batteries may be of any construction and arrangement of parts well known, or
otherwise, and of themselves they form no part of this invention: they are to be
suitably secured against accidental misplacement or 'up-setting.
A dial-face is provided on the upper portion of the front of the cabinet and
marked off in a circular line with even spaced graduations, 300 in number,
marked in steps of 25 each. A dial-hand or pointer is attached to a horizontal
arbor which is concentric with the graduated dial-face and passes loosely through
the front wall of the cabinet. The dial and its hand are covered and protected by
a glass-plate held in a metal bezel-ring hinged at one side to the front of the
cabinet, and at its opposite side fastened against being opened, except said fastening
be removed.
The hand-arbor inside of cabinet turns in bearings of an upright, projecting
upward from a vertical and stationary frame, composed of two horizontal bars
upper and lower, both at one end rigidly fastened by screw-bolts and nuts to one
of the side walls of the cabinet a vertical bar or brace joining the outer ends of
said horizontal bars and a horizontal bar extending from said vertical bar to the
other side wall of the cabinet, to which it is rigidly fastened by screw-bolts and
screw-nuts. All the parts of this frame are preferably of one
suitably made, to be strong, stiff and rigid.
pieco of metal and
Two parallel and horizontal rods are arranged one above the other and each
extending between the upright bar of the frame above described and the side
wall of the cabinet and rigidly fixed at its opposite ends to said bar and said
side wall.
A vertical metal bar or slide made stiff and rigid is provided and crosses from one
to the other and engaging the parallel rods and on both of which it is free to move,
forward and backward and said rods act as guides thereto.
A stiff coiled spring is loose on each guide-rod and confined thereon, end to end
between a vertical slide-bar and the inner face of the vertical bar making one part of
the metal frame before described. The vertical slide-bar has a horizontal metal bar
extension either of one piece with or rigidly attached to it and which is situated mid-
way between the two ends of said vertical slide and passes loosely through a guide-
opening of suitable shape therefor of the upright of said rigid and stationary frame
before described and thence, resting or bearing upon a portion of the upper face of
the horizontal bar in extension of said metal frame, to and through a guide-opening
of the side wall of the cabinet to the outer side of said wall, where it is provided with
an upright handle suitably shaped and located to be conveniently gripped by the
fingers of a persons hand and while resting the palm of the hand against a vertical
resting handle therefor of suitable shape. The two handles are in line with each
other and one handle is the farther removed from the side wall of the cabinet and to
which it is. rigidly attached by screw-bolts and nuts, through its horizontal extension
preferably in one piece with it.
The vertical frame described and its guide rods and springs coiled around each rod,
in combination with the vertical slide moving on said guide-rods its horizontal
extension or slide (preferably surrounded with a coiled spring confined end to end on
it as before described for the springs of guide-rods) having a finger gripping handle
and with a palm-resting handle constitute the dynamometer. This mechanism is
operated by gripping the handle with the fingers at the same time resting the palm
against the stationary handle and then pulling the finger-gripping and movable handle
toward and pressing against the palm-resting and stationary handle, all of which
against the coiled springs which are thereby compressed in accordance with the power
or force so exerted.
On the release of the finger-gripping or movable handle, the coiled springs by their
reaction, carry said handle, as also all other parts, or else allows of their return which
were under its action and were moved with it or effected by its said movement, to

page_text: their normal position and which is resisted, and in an elastic and yielding manner, by
the abutment of a coiled or buffer-spring which is on the horizontal slide outside of
the upright of the frame and between said upright and a fixed pin of said slide.
The movement of the vertical slide of the dynamometer mechanism as above
described, is communicated to the hand arbor and its hand through a cord, at one
end attached to it and passing under and in contact with the periphery of a loose
guide pulley-wheel, rotating on a stationary horizontal arbor of fixed uprights of the
horizontal extension of the frame, and at the other end connected to and more or
less wound around the hand-arbor and thus the hand is made to traverse the
dial-face and to indicate the amount of the gripping force or power exerted as
aforesaid.
The normal position of the hand is at graduation 300, which is when all parts of
the dynamometer are in their normal positions and from this graduation, on the
operation of the dynamometer as aforesaid, the hand moves round to the right which
is the direction in which the graduations are numbered as aforesaid, indicating
thereby the force or power exerted.
The rotation of the hand-arbor as aforesaid is against a coiled-spring at one end,
secured to a stationary support; cords are connected to the free end of spring and to,
and partially wound upon, hand-arbor.
The hand-arbor is prevented from rotating in the wrong direction by a radial pin
thereof in abutment against a stationary abutment.
A notch is provided in one edge of the horizontal slide-bar having finger-gripping
handle as before explained.
A vertical catch-lever engages said notch when the slide-bar is at rest or in its
normal position.
This catch has a bent spring connection fastened to a horizontal wooden cross-piece
or rail of the cabinet which is adapted to act also as an armature to an electro-magnet
suitably located therefor.
.
One pole of the electro-magnet is electrically connected by a wire with one pole
of the electric battery and which has its opposite pole electrically connected by a wire
to the upper metal contact of a downwardly inclining chute or conduit leading from
the outside of the cabinet through its side wall to the inside thereof. This chute has
a lower metal contact electrically connected, by a wire to the pole of the electric
The upper
battery opposite to that connected to the electro-magnet as before stated
metal contact has more or less spring or elasticity and it bears on the upper edge of
the nickel in the chute, pressing its opposite edge into close contact with the lower
metal contact and together closing the electric circuit of the electro-magnet which
attracting the armature thus disengages the catch-lever from the slide of the dyña-
mometer which leaves the dynamometer free to be operated from a then gripping of
the handles, as has been described. The outer end of the upper metal contact projects
into a position to be lifted by the upper end of a standard or electric circuit-breaker
which is carried by the slide-bar of the dynamometer mechanism.
A standard or circuit breaker and a metal contact of the nickel chute to be lifted
thereby arranged as so far particularly described secures a lift of the metal contact
on the slide of the bar in both directions.
A lift of the metal contact however may be had on a movement of the slide only
in one or either direction of its movements and preferably however on the return
movement of the slide by constructing the end of the standard or circuit-breaker
which works on the metal contact so as to be rigid in one, and to yield in the other
direction of movement of the slide. For illustration, the working end of the standard
is made separate from and at one side is hinged to and backed by a bent spring of
the standard proper, on which it is butted, end to end, and the whole is such, that said
working end can yield to pressure, applied to it on its side opposite to its hinged
side and when said pressure is released return to its normal position and be rigid
and unyielding to pressure applied to it at its hinged side and by all of which in the
first instance the standard passes freely under and by the metal contact and without
action thereon and in the second instance, acts thereon and secures its lift. A lift, of

page_text: the upper metal contact of the nickel-chute as aforesaid, releases the "nickel" to be
discharged from the chute by its own gravity and to be entered into the upper open
end suitably located therefor, of a vertical spout and leading down to the cash-box, into
which the "nickel" finally drops. Again, this lift of the upper metal contact of the
nickel-chute and discharge of the "nickel" thereby, all as above stated breaks the
electric circuit which was established as stated and so releases the attraction of
the electro-magnet on armature and the armature is freed to return to its normal
position, carrying with it the catch-lever which again engages with the notch of the
horizontal slide-bar of the dynamometer when said bar is returned to its normal
position, which occurs when the fingers are removed from the finger-gripping
handle.
The slide-bar may be provided with a series of notches each for the engagement of
the catch-lever and in the form of ratchet-teeth and presented in a direction so that,
at all times, the slide-bar released for its return movement can freely return whether
the electric circuit is or is not broken, and the slide bar with the electric circuit
broken will be held against movement in the direction to operate the dynamometer,
and whether the slide-bar has fully or only partially completed its return movement,
and the whole preventing more than a single operation of the dynamometer on the
insertion of a 65 nickel" in the chute.
An alarin or gong-bell is located on the top of the cabinet and a swinging-hammer
or striker is provided for sounding said bell, having a spring suitably applied to return
it to its normal position after each blow. This hammer serves as an armature to a
stationary electro-magnet at one pole, electrically connected by a wire to another
wire connecting one pole of electric battery with the upper metal contact of the chute
and at its other pole, by a wire to a spring metal finger which is located on the inside
of the cabinet, suitably insulated and is in position to have contact made with it by
a metal finger which is carried by the horizontal slide of the dynamometer and
suitably insulated therefrom and is electrically connected, by wire with another wire
leading from one pole of the electric battery to the electro-magnet and in electric
connection with the lower metal edge of the chute as before stated.
Contact between the spring-fingers establishes an electric-circuit through the
electro-magnet at the alarm-bell and thus puts the hammer of the bell in motion,
securing its sounding, and with said fingers out of contact, the electric-circuit
is broken.
The fingers are relatively arranged to make contact on a movement of the dial-
hand over a given and predetermined number of graduations of the dial-face and when
it reaches a given numbered graduation thereof,' as for instance, graduation
numbered 150 and thus by sounding the alarm-bell give notice thereof.
The "nickel" is an intermediary by which to make and break an electric circuit
through the electro-magnet and thereby release the dynamometer mechanism to and
secure it against action all as described. As so far particularly described, the inter-
mediary or "nickel" to perform its function, has bearing at opposite sides of the
edge on opposite located metal contacts each electrically connected to an electric
battery and both in a circuit of a common electro-magnet but obviously this function
of the "nickel" may be performed in other ways. For illustration, by locating the
metal contacts at the lower side of the chute, one directly above the other, and the
upper contact free to be placed into and out of contact with the lower contact from
the weight of the superimposed "nickel" in the chute and of the spring pressure
thereon of the upper edge of the chute suitably constructed and arranged therefor,
and also to be released from action from the movement of the standard or circuit-
breaker. One of the essential features of this invention and which distinguishes it
from all other dynamometers consists in the combination with a dynamometer of any
suitable construction and kind or character of an electric battery, an electro-magnet
a catch to hold the dynamometer against and to release it to action, a chute or
conduit to receive a predetermined intermediary such as a
03 five cent. nickel" and
metal contacts of said chute and an electric circuit breaker operated by the dyna-
mometer and all severally arranged and to operate with the intermediary suitably

page_text: located in the chute, and to automatically release said intermediary for its discharge,
all substantially as has been described.
As to this feature it is not intended to limit the invention to any particular form or
arrangement either of the dynamometer or the electric battery, or the electro-magnet,
or the intermediary or nickel-clute, or electric-circuit-breaker or the cabinet or
casing, or the means by which the dynamo neter is held against action, or through
which the dynamometer is to be operated as all of these may be obviously varied
in many ways or respects and without departing from the invention as herein
described.

Improvements in Apparatus for Receiving Payments and Permitting
the Testing of Muscular Strength in Exchange for such Pay-
ments, and for other Purposes.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co., Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :--
This invention is particularly designed for dynamometers adapted to test and
indicate the power or force exerted by the grip of a person's hand, although as will be
obvious from the description of it which follows, it is applicable to other dynamometers,
for illustration, recording weighing-scales and pulling and pushing machines, or
scales, etc. The invention more particularly pertains to the means for holding the
dynamometer against and for releasing it to action, through an article of a
predetermined weight, size or other dimensions or characteristic, such as a "five cent
nickel," to act as an intermediary when suitably applied. The invention consists, in
substance, in the combination with a dynamometer, for illustration, one suitable to
determine the power exerted by the grip of a person's hand, of a receiving chute or
conduit for a piece of metal or equivalent material of a predetermined weight, or
size or other dimensions, as for instance, a "five cent nickel," to act as an intermediary
as hereafter appears, and which chute has, in its length, two separate metal or other
suitable contacts, separately electrically connected and each and both arranged with
said intermediary in the chute and from the action thereof to make an electric circuit
through said metal contacts but at all other times to have and maintain said electric
circuit broken, and electric battery electrically connected to said electrical contacts of
said chute, a catch to engage and hold the dynamometer against and to release it to
operation, an electro-magnet in the electric circuit aforesaid, an armature for said
electro-magnet, to be operated by said magnet and thereby to release said catch from
the dynamometer but at all other times to allow said catch to remain in its said
engagement, and means operated by the dynamometer to release said intermediary to
be discharged from the chute and severally all otherwise constructed, combined and
arranged substantially as hereinafter described and whereby on the insertion of an
intermediary, such as a "five cent nickel" in said chute, an electric circuit will be
established, and thereby the dynamometer released to operate and in the operation of
the dynamometer said "five cent nickel will be released to be discharged from the
chure at the same time breaking the electric circuit, on which said catch is free
to return to its engagement with the dynamometer to again hold it, and as before,
against action.
Again the invention consists, in the combination with the above of an aların-
bell, a hammer for sounding said bell, an electro-magnet in an electric circuit, an
armature for said electro-magnet to be operated by said magnet and thereby to
secure through said hammer a sounding of said bell, and means in said electric circuit

page_text: by which to establish the circuit only on a given and predetermined movement of the
dynamometer.
In addition to the above, the invention consists of other constructions, combinations
and arrangement of the parts of the dynamometer, all substantially as hereinafter
described.
In the drawings, forming part of this specification, Figure 1 is a front elevation
of the cabinet of the dynamometer and its graduated dial-face. Figure 2 is a
front elevation of the working parts of the dynamometer, the front and dial-face
being removed. Figure 3 is a transverse horizontal section, enlarged, line 3-3,
figure 2. Figure 4 is a vertical section, enlarged and in detail, line 4-4, figure 2.
Figure 5 is a detail section, enlarged, of the nickel-chute. Figure 6 is a detail
sectional view, enlarged, of the nickel-chute and circuit-breaker as will hereafter
appear. Figure 7 is a plan view, enlarged and in detail as will hereafter appear.
In the drawings, A represents an upright cabinet of a rectilinear shape and
having a cabinet base B, by which to stand it on the floor or other suitable
support.
The cabinet A contains the dynamometer mechanism of this invention and it has
an opening and closing front door, under lock and key, and its base B contains the
electric battery or batteries C, shown in blank, and also a money receiving or cash
drawer or box D), under lock and key.
The batteries C may be of any construction and arrangement of parts well
known, or otherwise, and of themselves they form no part of this invention; they
are to be suitably secured against accidental misplacement, upsetting, &c.
E is a dial-face on the upper portion of the front of the cabinet. A and marked off
in a circular line with even spaced graduations, 300 in number, marked in steps
of 25 each. F is the dial-hand or pointer attached to a horizontal arbor G which is
concentric with the graduated dial-face E and passes loosely through the front
wall of the cabinet A. The dial E and its hand F are covered and protected by
a glass-plate held in a metal bezel-ring K, hinged at one side to the front of the
cabinet, and at its opposite side fastened against being opened, except said fastening
be removed.
.
The hand arbor G, inside of cabinet A, turns in bearings of an upright J projecting
upward from a vertical and stationary frame, composed of two horizontal bars L, L,
upper and lower, both at one end rigidly fastened by screw bolts and nuts to one M of
the side walls M, M2 of the cabinet A a vertical bar or brace N joining the outer ends
of said horizontal bars L, L, and a horizontal bar O extending from said vertical bar N
to the other side wall M³ of the cabinet, to which it is rigidly fastened by screw-bolts
and screw-nuts. All the parts of this fraine are preferably of one piece of metal and
suitably made, to be strong, stiff and rigid.
P, P are two parallel and horizontal rods one above the other and each extending
between the upright bar N of the frame above described and the side wall M of
the cabinet and rigidly fixed at its opposite ends to said bar N and said side wall.
Q is a vertical metal bar or slide made stiff and rigid and crossing from one to the
other and engaging the rods P, P, and on both of which it is free to move, forward
and backward, and said rods act as guides thereto.
R is a stiff coiled spring loose on each guide-rod P and confined thereon, end to
end, between slide-bar Q and the inner face of the vertical bar N making one part of
the metal frame before described. The vertical slide Q has a horizontal metal bar
extension S either of one piece with or rigidly attached to it and which is situated
midway between the two ends of said vertical slide and passes loosely through a guide-
opening T of suitable shape therefor of the upright N of said rigid and stationary
frame before described and thence, resting or bearing upon a portion of the upper
face of the horizontal bar O in extension of said metal frame, to and through a
guide-opening U of the side wall M2 of the cabinet A to the outer side of said
wall, where it is provided with an upright handle V suitably shaped and located
to be conveniently gripped by the fingers of a person's hand and while resting
the palm of the hand against a vertical resting handle W therefor, of suitable shape.

page_text: The two handles V, W are in line with each other and the handle W is the farther
removed from the side wall M² of the cabinet. and to which it is rigidly attached
by screw-bolts and nuts, through its horizontal extension W2, preferably in one piece..
with it.
The vertical frame L, N and O described and its guide rods P, P, and springs R,
coiled around each rod P, in combination with the vertical slide Q, moving on said
guide-rods P, its horizontal extension or slide S-(preferably surrounded with a coiled
spring R* confined end to end on it as before described for the springs R of guide-
rods P)-having a finger gripping handle V and with a palm-resting handle W
constitute the dynamometer. This mechanism is operated by gripping the handle V
with the fingers at the same time resting the palm against the stationary handle W
and then pulling the finger-gripping and movable handle V toward and pressing
against the palm-resting and stationary handle W, all of which is against the coiled
springs R, which are. thereby compressed in accordance with the power or force so
exerted.
On the release of the finger-gripping or movable handle V, the coiled springs R,
by their reaction, carry said handle, as also all other parts, or else allows of their
return which were under its action and were moved with it or effected by its said
movement, to their normal position and which is resisted, and in an elastic and yielding
manner, by the abutment of a short coiled or buffer-spring X, which is arranged on
the horizontal slide S outside of the upright N of the frame L, N, O and between said
upright N and a fixed pin X2 of said slide S.
The movement of the vertical slide Q of the dynamometer mechanism as above
described, is communicated to the hand arbor G and its hand F through a cord A²; at
one end attached to it and passing under and in contact with the periphery of a loose
guide pulley-wheel B, rotating on a stationary horizontal arbor C of fixed
uprights D2 of the horizontal extension O of the frame L, N, O and at the other end
connected to, and more or less wound around the hand-arbor G and thus the hand F
is made to traverse the dial-face and to indicate the amount of the gripping force or
power exerted as aforesaid.
:
The normal position of the hand F is at graduation 300, which is when all parts of
the dynamometer are in their normal positions and from this graduation, on the
operation of the dynamometer as aforesaid, the hand moves round to the right which
is the direction in which the graduations are numbered as aforesaid, indicating thereby
the force or power exerted.
The rotation of the hand-arbor G as aforesaid is against a coiled-spring E2 at one
end, secured to a stationary support F2; G2, G2 are cords connected to the free end of
spring and to, and partially wound upon, hand-arbor G.
The hand-arbor G is prevented from rotating in the wrong direction by a radial
pin H' thereof in abutment against a stationary abutment J.
K2 is a notch in one edge of the horizontal slide-bar S having finger-gripping
handle V as before explained.
1 is a vertical catch-lever engaging said notch K³ when the slide-bar S is at rest,
or in its normal position.
This catch L has a bent spring connection X2, fastened to a horizontal wooden
cross-piece or rait 0 of the cabinet and at P' it is adapted to act also as an armature
to an electro-magnet Q2, suitably located therefor.
One pole of the electro-magnet is electrically connected, by a wire R³, with one
pole of the electric battery C. and which has its opposite pole electrically connected
by a wire R, to the upper metal contact a of a downwardly inclining chute .or
conduit S, leading from the outside of the cabinet through its side wall M' to the
inside thereof. This chute S has a lower metal contact & electrically connected, by
a wire T, to the pole of the electric battery opposite to that connected to the
electro-magnet, as before stated. The upper metal contact a, (figure 5) has more or
less spring or elasticity and it bears on the upper edge of the nickel in. the chute,
pressing its opposite edge into close contact with the lower. metal contact band
together closing the electric circuit of the electro-magnet Q which attracting the

page_text: armature P2 thus disengages the catch-lever L' from the slide S of the dynamometer
which leaves the dynamometer free to be operated from a then gripping of the
handles V, W, as has been described. The outer end a² of the upper metal contact a
projects into a position to he lifted by the upper end of a standard or electric
circuit-breaker U which is carried by the slide-bar S of the dynamometer
mechanism.
A standard or circuit-breaker U2 and a metal contact a of the nickel-chute S² to
be lifted thereby arranged as so far particularly described secures a lift of the metal
contact on the slide of the bar S, in both directions.
A lift of the metal contact however may be had on a movement of the slide only.
in one or either direction of its movements and preferably however on the return
movement of the slide S by constructing the end of the standard or circuit-breaker
which works on the metal contact so as to be rigid in one, and to yield in the other
direction of movement of the slide S. For illustration, figure 6. U³ is the working
end of the standard U2. This working end is made separate from and at one side
is hinged to and backed by a bent spring U of the standard proper, on which it
is butted, end to end, and the whole is such, that said working end can yield to
pressure applied to it on its side opposite to its hinged side and when said pressure is
released return to its normal position and be rigid and unyielding to pressure applied.
to it at its hinged side and by all of which in the first instance the standard passes
freely under and by the metal contact a and without action thereon and in the second
instance, acts thereon and secures its lift. A lift of the upper metal contact a of the
nickel-chute S2, as aforesaid, releases the "nickel" to be discharged from the chute
by its own gravity and to be entered into the upper open end suitably located therefor,
of a vertical spout V2 and leading down to the cash box D, into which the "nickel"
finally drops. Again this lift of the upper metal contact a of the nickel-chute and
discharge of the "nickel" thereby, all as above stated, breaks the electric-circuit
which was established as stated and so releases the attraction of the electro-magnet
on armature P2 and the armature is freed to return to its normal position,
carrying with it the catch-lever L' which again engages with the notch K² of
the horizontal slide-bar S of the dynamometer when said bar is returned to its
normal position, which occurs when the fingers are removed from the finger-gripping
handle V.
The slide-bar S, figure 7, may be provided with a series of notches K' each for the
engagement of the catch-lever L and in the form of ratchet-teeth and presented in a
direction so that, at all times, the slide-bar S, released to its return movement can
freely return whether the electric circuit is or is not broken, and the slide-bar S with
the electric-circuit broken, will be held against movement in the direction to operate
the dynamometer, and whether the slide-bar S has fully or only partially completed
its return movement, and the whole preventing more than a single operation of the
dynamometer on the insertion of a"nickel" in the chute S².
A is an alarm or gong-bell located on the top of cabinet A and B³ is a swinging
hammer, or striker, for sounding said bell, having a spring suitably applied to return
it to its normal position after each blow. This hammer serves as an armature to a
stationary electro-magnet D³, at one pole, electrically connected, by a wire E³, to the
wire R³, connecting one pole of electric battery C with the upper metal contact a of
chute S and at its other pole, by a wire F3, to a spring metal finger G³, which is
located on the inside of the cabinet A, suitably insulated, and is in position to have
contact made with it by a metal finger H³, which is carried by the horizontal slide S
of the dynamometer and suitably insulated therefrom and is electrically connected, by
wire J³, with the wire leading from one pole of the electric battery Č to the electro-
magnet Q and in electric connection with the lower metal edge b of the chute S³, as
before stated.
Contact between spring-fingers G³, H³, establishes an electric-circuit through the
electro-magnet D at alarm-bell A' and thus puts the hammer of the bell in. motion,
securing its sounding, and with said fingers out of contact, the electric-circuit.is
broken.

page_text: The fingers G³, H³, are relatively arranged to make contact on a movement of the
dial-hand F over a given and predetermined number of graduations of the dial-
face and when it reaches a given numbered graduation thereof, as for instance,
graduation numbered 150 and thus by sounding the alarm-bell A³ give notice
thereof.
The "nickel" is an intermediary by which to make and break an electric circuit
through the electro-magnet D³ and thereby release the dynamometer mechanism to
and secure it against action all as described. As shown, and so far particularly
described, the intermediary, or "nickel" to perform its function, has bearing at opposite
sides of the edge on opposite located-metal contacts each electrically connected to an
electric battery and both in a circuit of a common electro-magnet, but obviously this
function of the "nickel" may be performed in other ways. For illustration, (figure 6)
by locating the metal contacts a, b, at the lower side of the chute, one directly above
the other, and the upper contact free to be placed into and out of contact with the
lower contact from the weight of the superimposed "nickel" in the chute and of the
spring pressure thereon of the upper edge a³ of the chute suitably constructed and
arranged therefor, and also to be released from action from the movement of the
standard or circuit-breaker U2. One of the essential features of this invention and
which distinguishes it from all other dynamometers consists in the combination with a
dynamometer of any suitable construction and kind or character, of an electric
battery, an electro-magnet, a catch to hold the dynamometer against and to release it
to action, a chute or conduit to receive a predetermined intermediary, such as a "five
cent nickel" and metal contacts of said chute and an electric-circuit-breaker operated
by the dynamometer and all severally arranged and to operate with the intermediary
suitably located in the chute, and to automatically release said intermediary for its
discharge, all substantially as has been described.
As to this feature it is not intended to limit the invention to any particular form
or arrangement, either of the dynamometer or the electric battery, or the electro-
magnet, or the intermediary or nickel-chute, or electric circuit-breaker or the cabinet
or casing, or the means by which the dynamometer is held against action, or
through which the dynamometer is to be operated, as all of these may be obviously
varied in many ways or respects and without departing from the invention as herein
described.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed as communicated to me by my
Foreign Correspondent, I declare that I make no claim broadly to the combination
with a dynamometer of mechanism for holding the dynamometer against and for
releasing it to action as it is not new, but I declare that what I claim is :-
First. In combination, a dynamometer, an electric battery and an electro-magnet,
electrically connected, an armature to said magnet, means to hold the dynamometer
against and to release it to action, a chute or conduit having separate metal contacts,
separately electrically connected with said battery and said magnet, and otherwise
constructed and arranged to make electric circuit through said magnet with an inter-
mediary, such as a "five cent nickel," placed in and applied to the said metal contacts
of said chute, and an electric circuit-breaker and intermediary-releasor, operated by
the dynamometer, all constructed, arranged and combined together and to operate,
substantially as described, for the purpose specified.
Second. In combination, a dynamometer, an electric battery and an electro-magnet
electrically connected, an armature to said magnet, means to hold the dynamometer
against and to release it to action, a chute or conduit having oppositely located metal
contacts a, b, separately electrically connected with said battery and said magnet and
otherwise constructed and arranged to make electric circuit through said magnet with
an intermediary, such as a "five cent nickel," placed in and applied to the said metal
contacts of said chute, and an electric circuit breaker and intermediary-releasor
operated by the dynamometer all constructed, arranged and combined together and
to operate, substantially as described, for the purpose specified.

electrically connected, an armature to said magnet, means to hold the dynamometer
against and to release it to action, a chute or conduit having opposite located metal
contacts a, b, separately electrically connected with said battery and magnet, and
one at least adapted to be vibrated and otherwise constructed and arranged to make
electric circuit through said magnet with an intermediary, such as a "five cent nickel,"
'placed in and applied to the said metal contacts of said chute, and an electric circuit-
breaker and intermediary-releasor, composed of a part operated by the dynamometer
and so operated made to vibrate, either or both of said metal contacts, all con-
structed, arranged and combined together and to operate, substantially as described,
for the purpose specified.
Fourth. In combination, a dynamometer, an electric battery and-an electro-magnet,
electrically connected, an armature to said magnet, means to hold the dynamometer
against and to release it to action, a chute or conduit having separate metal contacts,
separately electrically connected with said battery and said magnet, and otherwise
constructed and arranged to make electric-circuit through said magnet with an
intermediary, such as a "five cent nickel," placed in and applied to the said metal
contacts of said chute, and an electric circuit-breaker and intermediary-releasor
operated by the dynamometer, in combination with an alarm or gong-bell A³, a hammer
to said bell, an electric battery and an electro-magnet D³ electrically connected, an
armature to said magnet to operate said hammer, metal contacts G³, H³, each
electrically connected with said electro-magnet and one arranged to be moved into and
out of contact with the other by the dynamometer, all substantially as described,
and for the operation and purpose specified.
Fifth. In combination, a vertical frame L, N, O, rigidly fastened at opposite sides of
a cabinet or other suitable support, and having stationary guide-rods P, P and coiled
springs R, R confined, end to end; on said frame, a vertical slide Qmoving on said
guide-rods and against and with said springs, and having a horizontal extension S
with vertical finger-gripping and moving handle V and a stationary palm-resting
handle W, substantially as described, for the purpose specified..
