PROVISIONAL SPECIFICATION.
A New or Improved Machine for Squeezing and Cementing or
Glueing Leather Belting.
I, SAM HALEY, of the Firm of Thomas Haley and Co., of Bramley, near Leeds,
in the County of York, Machine Makers, do hereby declare the nature of this
invention to be as follows:-
-
This invention relates to the construction and arrangement of a new form. of
machine for squeezing together (after being cemented) strips or lengths of leather
for driving belts. The machine comprises a pair of rollers mounted in suitable
framework between which rollers tho cemented belting passes for the purpose of
binding the leather together and also for squeezing out surplus cement. The upper
squeezing roller is made adjustable by means of screws to suit varying thicknesses
of leather. If the leather belting passing between the squeezing rollers gets out
of truth or is not uniform, I provide means whereby the bottom roller can be
lowered so as to relieve the pressure off the belting to permit the said belting to be
re-adjusted which when done, the bottom roller is raised again so as to nip the
leather to the required degree. The means I employ for lowering the bottom
roller consists in using a pair of toggles the upper one of which is underneath the.
pedestals which support the shaft of the bottom roller. These toggles are in con-
nection with a horizontal ram having a slut at the opposite end, in which slot
I place a cam, actuated by a lever; therefore when this lever is operated in one.
direction the cam causes the toggles to assume a vertical position whereupon the
bottom roller is at its highest point squeezing the leather but the reverse motion of.
the said lever withdraws the slotted horizontal ram causing the toggles to assume
an inclined position permitting the bottom nipping roller to descend for the purpose..
of easing the leather, whereby the belting can be re-adjusted.
When the bottom nipping roller is lowered the upper nipping roller would
follow after it, but to prevent this I employ a set screw and lock, nuts the head of
the set screw occupying a position under the pedestal of the shaft carrying the
upper squeezing roller which set screw is adjusted to prevent the upper roller from
lowering beyond a given point. In order to guide the leather passing between the.
nipping rollers I employ a slotted table on which are adjustable cheeks or pieces of
metal which can be set at different distances apart to suit the various widths of
belting. The upper squeezing roller may be covered with india rubber cotton fibre
or fabric or other suitable material. I would here observe that the toggles and
slotted ram and cam together with the actuating lever may be employed in
connection with plate press or square bottom presses which are now employed for
squeezing and cementing leather belting.

1, SAM HALEY, of the Firm of Thomas Haley and Co., of Bramley, near Leeds,
in the County of York, Machine Makers, 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 relates to the construction and arrangement of a new form of
machine for squeezing together (after being cemented) strips or lengths of leather
for driving belts. The machine comprises a pair of rollers mounted in suitable
framework between which rollers the cemented belting passes for the purpose of
binding the leather together and also for squeezing out surplus cement.
The upper
squeezing roller is made adjustable by means of screws to suit varying thicknesses
of leather.
If the leather belting passing between the squeezing rollers gets out of truth or
is not uniform, I provide meaus whereby the bottom roller can be lowered so as to
relieve the pressure off the belting to permit the said belting to be re-adjusted
which when done, the bottom roller is raised again so as to nip the leather to the
required degree. I also provide means for adjusting the position of the upper
squeezing roller and means are also employed for guiding the leather between the
said nipping rollers.
In order to explain my improvements more fully reference is made to the
accompanying sheet of drawings wherein Fig. 1 is end elevation of my improved
machine, Fig. 2 front elevation, and Fig. 3 an enlarged sectional elevation, shewing
the toggle levers and ram.
A, Fig. 1, are frames or standards being connected together by a beam B and tie
rods C.
The upper squeezing roller is shewn at D mounted in pedestals E and made
adjustable up and down by screws F operated by hand wheel or lever G. The
lower squeezing roller is shewn at H mounted in adjustable pedestals 1, such said
roller being made to rotate at the required speed by worm wheel J Fig. 2 operated
by worm K Fig. 1 fixed upon the driving shaft L Fig. 1 and driven by strap and
pulley M. The top and bottom squeezing rollers are not necessarily connected
together by driving gear, but it is preferable to do so, to prevent the upper
squeezing roller from slipping.
The primary object of my invention in this machine is to provide facilities for
re-adjusting the belting which is being squeezed when such belting gets out of truth
or is not uniform.
To effect my object I provide means for lowering the bottom squeezing roller so
as to take the pressure off the belting, and the means I employ for lowering the
said roller consist in the use of a pair of toggles N and O, the upper end of the
top toggle lodging underneath the pedestals I which support the shaft of the bottom
roller. These toggles are in connection with the horizontal ram or levers P, which
rams are provided at one end with a slet Q Fig. 3 for receiving a cain R, Figs. 3
and 4, which may be either keyed on the shaft S Fig. 4 or the said cam may
be cut out of the shaft somewhat like a crank as shewn in elevation Fig. 4 and
cross section Fig. 5.
On one end of the cam shaft S is secured a lever arm T therefore when the
machine is in operation and squeezing a newly cemented belt or belts, the lever T
is in a horizontal position and the bottom squeezing roller occupies its highest
position and the toggles N, O, occupy a vertical position as shewn in Fig. 3, but
should the cemented belt have got out of truth and require adjusting the lever
arm T is brought to a vertical position causing the flat part of cams R to occupy

or become vertical and thus draw back the toggles N, O, past the "dead centre
or vertical position, when the weight of the bottom roller will commence to follow
and act upon the said toggles and cause them to assume an inclined position as
shewn in dotted lines in Fig. 3 thus the pedestal I and the bottom squeezing roller
will descend, consequently the pressure is removed off the belting and it is free to
be adjusted.
When the toggles are changing from a vertical to an inclined
position, the rams P move backwards horizontally the stud U being employed to
prevent the said rams from rising. When the belting has been re-adjusted the
operative moves the hand lever T into a horizontal positition as shewn in Fig. 1
causing the rams P to advance and the toggles to become vertical whereby the
bottom squeezing roller is again raised.
the
In order to lessen the friction of the toggles in the recesses in which they lodge,
I prefer to make the ends of each toggle of smaller size than the recesses;
ends of the toggles may however be made with a V after the manner of levers in
weighing machines.
The frames A of the machine are cored out at the bottom to allow for movement
of the ram and toggle.
When the bottom nipping roller is lowered the upper nipping roller would follow
after it, but to prevent this I arrange that the pedestals E, shall rest upon the
points or heads of set screws V made secure by lock nuts in the plates W which are
cast to or form an integral part of the framework A.
The said set screws also prevent the upper squeezing roller from lowering beyond
a given and predetermined point.
The springs a and screws are adjustable to any required pressure as regards the
top roller D. The said screws bare right handed, and made with collars c,
therefore if the said screws bare unscrewed out of blocks E the said blocks will
drop to the point of the screws V and rest there. When the screws bascend
and leave the blocks, the collars e will compress the springs a between the
collars and the top beam B. The spindles of screws run loosely through
holes in the block B consequently any amount of pressure can be placed on the
top roller D, but the pressure is lifted off the screws V, when the toggles are
placed into their vertical or highest position.
It will therefore be understood that the pressure which rested on the points of
screws V is transferred to the grip between the rollers as soon as the bottom roller
is raised by lever T.
In order to guide the leather belt between the nipping rollers, I make headed
slots in the table X in which are adjustable cheeks or pieces of metal Z which
plates can be set at different distances apart to suit the various widths of belting.
The upper squeezing roller may be covered with india rubber cotton, fibre or
fabric or other suitable material, and I would here observe that the toggles N, O,
and slotted ram P and cam R together with the actuating lever T may all be
employed in connection with plate press or square bottom presses which are now
mployed for squeezing and cementing leather belting. In this instance the upper
oggle N would abut against the underside of the bottom press plate.
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 :-
Firstly, In a machine for squeezing and cementing leather belting having an
upper and lower squeezing roller, the use therein of toggles N, O, and ram P
together with cam R and operating lever T for raising and lowering the bottom
pressing roller all arranged and operating in the manner described and shewn in the
drawings.
Secondly. In a machine for squeezing and cementing leather belting having an
apper and lover squeezing roller, the use therein of toggles N, O, and ram P for
raising and lowering the bottom pressing roller, in combination with the adjustable

page_text: screw V for adjusting the position of the upper squeezing roller in the manner
described and shewn in the drawings.
Thirdly. In a machine for squeezing and cementing leather belting having an
upper and lower squeezing roller, the use therein of toggles N, O, and ram P for
raising and lowering the bottom pressing roller, adjustable screw V for adjusting
the position of the upper squeezing roller, in combination with a slotted table ✗
for adjusting the guide cheeks or plates Z all arranged and combined substantially
in the manner described and shewn in the drawings.
