Improvements in or connected with Apparatus or Appliances for
Putting Bands or Belts upon Drums, Pulleys, and the like.
:
I, LEWIS CHARLES WALLACH, of 57 Gracechurch Street, in the City of
London, Merchant, do hereby declare the nature of this invention to be as
follows:--
This invention refers to an improved apparatus or appliance for placing bands
or belts upon drums, pulleys, and the like, and the object of the invention is
to produce a simple, effective, adjustable and cheaply. manufactured appliance.
such as may be used for pulleys of varying diameters and speed, and for placing
thereon hands or belts of varying widths, with greater ease, certainty and
safety than heretofore. In apparatus hitherto proposed for this purpose, clips
or forks have been employed for temporarily fixing the belt onto the wheel
until the rotation of the latter drew the belt over the pulley when the spring
clip was pulled off, but such a means is not readily adaptable to varying
dimensions of belts and pulleys, and is inefficient and uncertain in action; again
it has been proposed to employ slotted plates or segments sliding upon and into each
other and having a pin upon which the belt was to be carried round the pulley,
the slotted plates or segments being intended to become elongated as the belt was
passed round the pulley, also apparatus. has been devised having loosely jointed
arms to carry the belt-carrying spindle, and in some cases the joints have been
fitted with springs adapted to be forced over when in action. All these similar
appliances have failed to answer the requirements and have been more or less
ineffective, and in some cases actually dangerous to the safety of the operator.
Now according to my invention I provide means whereby a rod having a belt-
carrying spindle located at the end thereof, is mounted so as to be capable of
rotation upon a handle or shaft, the rod being easily adjustable in length to the
semi-diameter of any pulley or drum while the rotation of the rod is capable of
being controlled by the operator, the said rod being held rigid or in any desired
position relatively to the handle portion and is entirely free in its action to follow
the rotation of the pulley, as soon as the operator has placed same with the belt
or strap to be placed on the pulley in proper working position and has released
the clutch.
A convenient construction is to provide a handle or rod of wood, or tubular
metal or any suitable material of light weight and proper length, and near the
upper end thereof I fix a bracket from which a tubular sleeve is supported
laterally in such manner as to be capable of rotation in a vertical plane. Into this
sleeve is inserted a rod or tube held adjustably lengthwise within the sleeve by
say a set screw, and the second rod is fitted at its upper end with the belt-carrying
spindle extending at right angles thereto; this spindle is clamped onto its bearing
on the end of the rod by a suitable clamping device or a set screw, whereby
its greater projecting length may be varied according to the width of pulley face
on which the belt is to be placed and the spindle is provided at its outer end
with a fixed flanged retaining collar also adjustable by a set screw; near the
rod end of the spindle there is also a collar having a somewhat larger flange to
prevent the belt from slipping and free to revolve to reduce friction and it is
between these two flanged collars and upon the spindle that the belt to be placed

page_text: upon the pulley is supported and by proper adjustment as has been shown, same
may be applied to any width of pulley or drum.
In order that the rod may be held in rigid alignment, or in any desired
position with the handle when requisite, I provide a suitable clutch device for
locking the said two parts together in the desired position and capable of release
by the operator at the proper moment. Such a clutch device may consist of an
open fork adapted to embrace the rod, and having an extension which is pivotted
to the handle, the extreme rear end of the extension of the fork having a connection
rod, chain, or cord, extending down the handle and within convenient reach of the
operator.
When the appliance is to be used, the distance between the flanged collars on the
spindle should be adjusted to easily take the face of pulley, and the length of
the rod, that is between the belt-carrying spindle and the tubular sleeve, may be
adjusted in length to accord with the semi-diameter of the pulley or wheel, while
the clutch device should lock the rod and handle in alignment, or in the required
position. The spindle is then applied under the beiting so that the latter lies
thereon between the flanged collars, and the spindle of the apparatus is then lifted
cnto the revolving pulley, the spindle being placed on the pulley face coming into
contact therewith and is carried around the pulley; when this motion has com-
menced, the operator draws the clutch connection and releases the rod (hooking
the connection onto the handle) the rod then turns on its pivot and the spindle
following the motion of the pulley the belt is thereby carried around the pulley
the said spindle being released at the point where the belt leaves the circumference
or face of the pulley and leaving the belt on the latter.
I do not limit myself to the exact construction of the pivotal connection between
the bracket on the handle and the sleeve carrying the rod, nor to the fixing and
controlling arrangement of the rod, the former may for example be connected by a
headed stud capable of turning in or upon the sleeve or bracket, or both, or one
of these parts may have a laterally projecting sleeve adapted to take a trunnion
from the other part. Also the construction of the clutch device may be varied,
thus for example instead of the fork as described I may provide a spring pin
or latch on one of the parts to take into a recess or bed of the other part, or a
clutch may be provided of ordinary construction to lock the pivot between the
bracket and sleeve. Or the trunnion of the rod may extend through the bracket
on the handle and be provided with a crank or disc operated by a connecting rod
or rods extending down the handle, whereby the operator is enabled to fix the rod
in any desired position, or to control its motion during the whole of its action, or
other convenient controlling devices may be employed such as a spring controlled
clutch or a spring bolt taking into notches on the disc.

Improvements in or connected with Apparatus or Appliances for
Putting Bands or Belts upon Drums, Pulleys, and the like.
I, LEWIS CHARLES WALLACH, of 57 Gracechurch Street in the City of
London Merchant, 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 refers to an improved apparatus or appliance for placing bands
or belts upon drums, pulleys, and the like, and the object of the invention is to

page_text: produce a simple, effective, adjustable and cheaply manufactured appliance, such
as may be used for pulleys of varying diameters and speed and for placing thereon
bands or belts of varying widths, with greater ease, certainty and safety than
heretofore. In apparatus hitherto proposed for this purpose clips or forks have
been employed for temporarily fixing the belt on to the wheel until the rotation of
the latter drew the belt over the pulley when the spring clip was pulled off, but
such a means is not readily adaptable to varying dimensions of belts and pulleys,
and is inefficient, and uncertain in action; again it has been proposed to employ
slotted plates or segments sliding upon and into each other and having a pin upon
which the belt was to be carried round the pulley, the slotted plates, or segments
being intended to become elongated as the belt was passed round the pulley, also
apparatus has been devised having loosely jointed arms to carry the belt-carrying
spindle, and in some cases the joints have been fitted with springs adapted to be
forced over when in action. All these and similar appliances have failed to answer
the requirements and have been more or less ineffective and in some cases actually
dangerous to the safety of the operator.
Now according to my invention I provide means whereby a rod having a belt-
carrying spindle located at the end thereof, is mounted so as to be capable of
rotation upon a handle or shaft, the rod being easily adjustable in length to say,
the semi-diameter of any pulley or drum while the rotation of the rod is capable
of being controlled by the operator, the said rod being held rigid or in any desired
position relatively to the handle portion and is entirely free in its action to follow
the rotation of the pulley, as soon as the operator has placed same with the
belt or strap to be placed on the pulley in proper working position and released
the clutch.
In order that my said invention may be more readily understood I will now
describe same with reference to the accompanying drawings,
Figs. 1 and 2 showing an arrangement of apparatus wherein the said rotating
rod may be held rigid in one position relatively with the handle portion and released
when desired while
Figs. 3 4 and 5 shew an example where the rotating rod may be held in any.
desired position and also released when required.
Referring to the arrangement shewn in side elevation at Fig. 1, A is the handle
or rod of wood, or tubular metal or any suitable material of light weight and
proper length; near the upper end of the handle A I fix a bracket B from which
a bearing sleeve B¹ extends whereby a tubular sleeve C is supported laterally in
such manner as to be capable of rotation in a vertical plane; on the drawing the
tubular sleeve C has a lateral stud shaft proceeding into and held within the
bearing sleeve B¹ extending from the bracket B. Into the tubular sleeve C is
inserted a rod or tube D held adjustably lengthwise within the sleeve C by say
set screws C¹, and the rod D is fitted at its upper end with the belt-carrying
spindle E extending at right angles thereto; this spindle E is fixed in any suitable
manner to the end of the rod D.
In some cases the spindle E may be made adjustable in its socket at the
end of the rod D by say, a suitable clamping device or a set screw, whereby
its greater projecting length may be varied according to the width of pulley face.
on which the belt is to be placed. The spindle E is provided at its outer end with
a fixed flanged retaining collar E¹ adjustable by a set screw; near the rod end of
the spindle E, there is also a collar E2 having a somewhat larger flange to prevent
the belt from slipping and free to revolve to reduce friction and it is between these
two flanged collars E E2 and upon the spindle E that the belt to be placed upon
the pulley is supported and by proper adjustinent as has been shown, same may be
applied to any width of pulley or drum.
In order that the rod D may be held in rigid alignment or in any desired
position with the hardle when requisite, I provide a suitable clutch device for
locking the said two parts together and capable of release by the operator at the
proper moment.
Such a clutch device when the rod D is to be held rigidly with

page_text: the handle portion A and released when required may consist as shewn at Figure 1
and also by the enlarged plan view of the clutch device at Figure 2, of an open
fork G adapted to embrace the rod D, and having an extension G¹ which is
pivotted to the handle bracket B, the extreme rear end of the extension G¹ of the
fork G having a connection rod, chain or cord G³ extending down the handle A
and to within convenient reach of the operator.
Figure 3 is a side elevation, and Fig. 4 a front elevation shewing by way of
example, an arrangement where the rod D may be held in any desired position with
the handle A and released when required. To this end I extend the stud shaft C²
from the sleeve C entirely through and beyond the bracket B and I fix thereon
one half of a clutch block G, the opposite half G₁ being located loosely on the
shaft C2 and normally held up to and engaging with the part G by means of a
spring H. K is a bell crank lever fulcrummed on the handle A one forked arm
thereof controlling the clutch block G', while the other arm is attached to the
controlling cord rod or chain G². In this construction the rod D may be held in
any required angular position as indicated at Fig. 4 by the dotted lines. By
pulling the cord G2 the lever K will distance the clutch block G', and the rod Ď
will be free to turn to the position required.
When the appliance is to be used, the distance between the flange collars E E³
on the spindle E should be adjusted to easily take the face of pulley, and the length
of the rod D, that is between the belt-carrying spindle E and the tubular sleeve C,
may be adjusted in length to accord with the semi-diameter of the pulley or wheel,
while the clutch device should lock the rod D and handle A in alignment or in the
required position. The spindle E is then applied under the belting so that the
latter lies thereon between the flanged collars E' E2, and the spindle E of
the apparatus is then lifted on to the revolving pulley, the spindle being placed on
the pulley face coming into contact therewith and is carried around the pulley;
when this motion has commenced, the operator draws the clutch connection and
releases the rod D; the rod D then turns on its pivot and the spindle E following
the motion of the pulley the belt is thereby carried around the pulley the said
spindle E being released at the point where the belt leaves the circumference or
face of the pulley and leaving the belt on the latter.
I do not limit myself to the exact construction of the pivotal connection between
the bracket on the handle and the sleeve carrying the rod nor to the fixing and
controlling arrangement of the rod and as will be well understood the construction
of the clutch device may be varied, thus, for example, I may provide a spring pin
or latch on one of the parts to take into a recess or bed of the other part, or a
clutch may be provided of ordinary construction to lock the pivot between the
bracket and sleeve. Or the trunnion of the rod may extend through the bracket
on the handle and be provided with a crank or disc operated by a connecting rod
or rods extending down the handle, whereby the operator enabled to fix the
rod in any desired position, or to control its motion during the whole of its
action.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is-
1. In apparatus or appliances for placing bands or belts upon drums, pulleys,
and the like the combination with a supporting member or handle, of a rod pivotally
and adjustably connected to the handle and having the belt lifting spindle located
at one end thereof, together with a clutch or equivalent device and an operating
rod, cord, or chain therefrom, whereby the revolvable rod may be held rigid in oue
position relatively to the handle or may be held in any desired position relatively
thereto and in either case released or allowed to revolve when required substantially
as set forth.
2. In apparatus or appliances for placing bands or belts upon drums, pulleys
and the like the arrangement and combination of parts substantially as and for

page_text: the purposes described with reference to Figs. 1 and 2 of the accompanying
drawings.
3. In apparatus or appliances for placing bands or belts upon drums, pulleys,
and the like, the arrangement and combination of parts substantially as and for
the purposes described with reference to Figs. 3, 4 and 5 of the accompanying
drawings.
4. The general arrangement and combination of parts composing my improved
apparatus or appliance for placing bands or belts upon drums, pulleys, and the like
all constructed and acting substantially as and for the purposes hereinbefore.
described.
