PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Gloves.
We ERNEST GOODWIN COLTMAN and THOMAS BILLSON trading as W. & R.
Coltman, both of Church Gate Leicester in the County of Leicester, Glove
Manufacturers, do hereby declare the nature of our said invention to be as
follows:-
Whereas in the ordinary use of gloves; the palms of the hands usually wear out
very much quicker than the backs and other parts, which rapid wear is caused by
carrying umbrellas, walking sticks and other articles.
Now the object of our invention is to manufacture gloves in such a manner that
the palms or inside portions of the hands are of thicker fabric than the back part, or
other portions of the hands, in order that such thickened portions may be the better
able to resist ordinary wear and tear.
In carrying out our invention we effect the thickening of the palms by what is
commonly known in Hosiery manufacture as "splicing." This may be effected by
using either thicker weft or warp at that part, or both thicker weft and thicker
warp, or by throwing into the fabric a greater number of warp threads or weft
threads, or by throwing in a greater number of both warp and weft threads, or it
may be effected by weaving double or two-ply cloth at such parts.
The above mentioned operations are effected by weaving or knitting the gloves in
hosiery frames of the class known as the straight "bar," hosiery frames, or any kind
of weaving looms driven by steam power or otherwise."

page_text: entering between the wedging inclines K K in order to force apart the levers G G.
The engaging surfaces of this block may be either curved or straight. This con-
struction is subject to the disadvantage that a less extended frictional surface is
provided than if pivoted shoes were employed, which are so mounted that they can
adjust themselves to parallelism with the face of the wedging incline. Figure 14
shows a modified means for spreading apart the levers G G upon depressing the
treadle, such means consisting of a lever arm d bearing a wheel or roller d' and to
the projecting end of which arm the rod f is jointed. On pulling down this rod
the roller drolls against the face of the opposite lever G, and as the arm d
approaches the horizontal it forces the two levers apart.
Figure 15 shows how my invention may be applied to an existing construction
of drop-hammer of the type having a wooden board fastened to the hammer-head
and projecting upward between the two friction rollers. One of the friction rollers
is stationary, the other roller alone being moved toward or from it, motion being
communicated to it by oscillating an excentric bearing sleeve M, which turns in
bearings in the supporting frame. Such a construction of oscillating bearing sleeve
is well known in the art. have therefore not shown this construction in detail
in Figure 15. There is only one wedging incline K which is formed on a separate
piece or block L, which is clamped or fastened to the upright board at any desired
point. A friction shoe J is arranged to be displaced by this wedging incline, and
is pivoted to an elbow lever N, against which a spring S presses in order to force
the shoe J toward the upright board of the hammer. A stop-t is provided to limit
the movement of the lever N. This lever is connected by a link u to a lever arm v,
projecting from the excentric sleeve M, so that the latter is oscillated by the vibratory
movement of the lever N. When the lever N is drawn down the movable friction-
roller E is moved toward the immovable roller, thereby clamping the hammer board
between them and elevating the hammer. When the hammer nears the top of its
movement, its incline K encounters the shoe J and presses it outwardly, thereby
tilting the lever N against the tension of the spring S, and also through the link u
moving up the arm v and oscillating the sleeve M in such direction as to move to
movable friction roller sufficiently away from the immovable roller to release the
hammer-board. The hammer then remains suspended, held by the friction between
the shoe J and incline K. This modification is introduced simply to show that only
one incline K and shoe J may be employed in place of two, and that other means
of relatively moving the friction rollers in order to release or engage the hammer
may be employed with my present invention. Any known means for releasing the
hammer may be used with this construction.
My invention may be in part availed of by the employment of a partial equivalent
for the wedging inclines K K and shoes J J. Such a construction is shown in
Figure 16. In this figure the lever frames G G are inverted, being pivoted to the
frame at their upper ends, and their lower ends carry toggle arms which are
normally held at the angle shown by stops a formed on the lever frames. When
the hammer ascends shoulders y formed on it encounter the free ends of these toggle
arms and form therewith a knuckle joint, forcing the toggle arms into a straight
line in order to separate the levers G G, and they may move sufficiently beyond a
straight line, so that the opposite inclination of the toggle arms z = will suffice under
the tension of the springs S S to hold the hammer suspended, or the hammer may
simply straighten the toggle arms and be held suspended by pawls or otherwise in.
any manner heretofore employed. The hammer may be released by the application
of the same toggles d d and rod fas shown in Figure 2, or by any other means for
forcing apart the levers G G.
"
It will be understood that although in the preferred construction of my invention
the action of the wedging inclines effects two purposes,-viz.,-the automatic release
of the lifting mechanism and the suspending of the hammer, yet these two functions
are not necessarily united, since the action of the wedging inclines may serve only
to disengage the lifting mechanism or only to suspend the hammer. In either of
B

page_text: mese cases any mechanism formerly employed may be substituted for effecting th
other function.
It will also be understood that with reference to the function of disengaging th
lifting mechanism the wedging inclines will find their equivalents in any mechanica
devices by which the momentum of the ascending hammer is converted into a latera
thrust sufficient to overcome the action of the springs in pressing the friction rollers
together, and thereby to force these rollers apart.
Figure 16 illustrates one such equivalent device.
The construction shown in
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim in respect of drop-hammers is :-
