Improvements in Machines for Shaping Horse Collars.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, 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:-
The object of my invention is to provide a horse collar shaping machine with
power devices for driving the travelling draw-head, so constructed that the pre-
determined amount of strain applied to the draw-head will be automatically
produced and automatically maintained without any attention of the operator
other than simply starting the machine.
Another object of my invention is to provide reversing mechanism for releasing
the strain from the collar, so constructed that the reversing transmitter will be
automatically thrown out of gear at the end of the reverse movement of the
transmitter, without any attention from the operator, except to move the reversing
lever for starting the operation.
Another object of my invention is to so arrange the power transmitting
device of the machine, that while the predetermined strain can be maintained
continuously for any desired length of time, the main shaft which produces this strain
can likewise be employed in driving additional machines, each of the machines
being independent of the other in its operation. This is an important advan-
tage, as any number of machines may be mounted side by side and operated by
a single line of shafting and controlled by one operator, because the power of
each machine is automatically unshipped when the desired degree of tension is
attained and the draw-head maintained under such tension. Each machine may
therefore be put in operation, maintained under a predetermined tension, or
reversed, independent of every other machine.
Various other features of my invention are more fully set forth in the descrip-
tion of the accompanying drawings making a part of this specification, in
which:-
Fig. 1, is a perspective view of the machine in position for use.
Fig. 2, is a top plan view partly in section.
Fig. 3, is a central vertical section of the friction releasing mechanism.
Fig. 4, is a top plan view of the power driving mechanism.
A, A, represent the frame pieces of the machine. B, B, the table supported.
thereon. C represents the form around which the collar is stretched.
a represents the driving shaft, upon this are mounted right and left hand
gears b, c.
d represents a bevel gear adapted to be engaged respectively with
gear bor c to drive in either direction. To accomplish this result the following
construction is preferably employed:
e, e, represent a frame on which the sleeve f is mounted. This frame rocks on
centers g. h represents the power shaft on which bevel gear d is mounted.

page_text: Said bevel gear d is connected to its shaft by a friction clutch, which clutch is
composed of the plain disk, i and the concave spring disk j which is made of
steel. represents a straining rod provided with a head k¹. represents a nut on
the end of said rod k for regulating the tension of the friction disk j. D repre-
sents the straining mechanism which is composed of a reciprocating draw-head
preferably mounted upon an alternately reciprocating screw shaft E. 2 repre-
sents a sprocket wheel, mounted upon and driven by shaft h. 3 represents
a chain connecting said sprocket wheel with a revolving nut F to drive the same,
the axis of said nut F has female threads engaging with the screw shaft E to
drive the same in either direction, thereby imparting strain to the collar or
releasing it therefrom. The shipping mechanism for controlling the reversing
gear is constructed as follows:-
H represents a vertical shaft operated by the setting lever I. K represents
a lever connected to the vertical rock shaft H. L represents a connecting rod
pivoted thereto and to the sleeve f.
in
M represents a spring for normally holding the setting lever I in a central
position thus holding the gear & normally out of engagement with gears b, c,
as in the position shown in Figure 4. m, n, represent hooks adapted to engage
the catch o on the setting lever I, for holding the gear d in mesh with either
gear or c, I provide a sleeve O, having shoulders r, r, engaging with the fric-
tion roll t, journalled on the head so that the sleeve O moves on shaft
unison with the gear d. The ends of said sleeve O, abut the inner face of
gears b, c, respectively and limit the mesh of the teeth of gear d with the
gcars b or c, thereby rendering their disengagement comparatively easy, In
order that the gear may be automatically released on the return movement of
the straining shaft, I provide a tripping mechanism which consists of the rod P
hinged to catch n and to the trip lever R which is thrown by the head S on screw
shaft E.
MODE OF OPERATION.
The gear wheels normally occupy the position shown in Figure 4 in which the
gears b, c, are running as idlers, the screw shaft E occupying the furthest
position inward, so that the rope G may engage with the hame recess of the
collar which is placed around the form block C. This collar form is of the usual
construction employed in hand stretching machines. Shipping lever I when
moved to the right brings bevel gear d into engagement with bevel gear b, which
drives the revolving nut F in the direction to drive the screw shaft E outward,
thus drawing the cross rope G and stretching the collar up to the form block.
The nut is turned so as to give the requisite amount of tension or compression
to the friction disk j at which point the gear will slip and cease to revolve, and
the strain applied to the collar by the rope will remain constant until released
by the reversing drive. This is accomplished by moving lever I out of engage-
ment with the catch m into engagement with catch n thus bringing bevel gear
into engagement with bevel gear c, which will drive the revolving nut F in the
direction to retract the straining screw shaft E, which as it arrives at the
desired limit of movement inward,; automatically trips the power slipping
mechanism by the engagement of the head S with the lever R and tripping rod l'
releasing the hook when the spring M will move the shipping lever I into
the position shown in Figure 2 and the bevel gear into the position shown in
Figure 4. Thus the power is automatically controlled by the friction clutch
on the outward movement of the straining shaft and by the tripping mechanism
on the inward movement of the straining shaft. This is a very material advan-
tage as a single operator can operate several machines receiving power from a
single main shaft: all the attention necessary being to move the shipping lever
and to put on and take off collars.
I believe I am the first to accomplish this result.
