Letters Patent No. 111,245, dated January 24, 1871.
IMPROVEMENT IN BOQT-CRIMPERS.
The Schedule referred to in these Letters Patent and maldng part of the same.
To all whom. 'it may concern:
Be it known that I, WrLfLrAM Ponsenovn, of St. Thomas, .in the county of.' Franklin and in the State of Pennsylvania, have invented certain new and useful Improvements in Boot-Grimper; and do hereby declare that the. following is'a full clear, and exact description thereof, reference' being had to the accompanying drawing and to the letters of reference marked thereon making a part of this specification.
The nature of my invention consists in the construction and arrangement of a boot-crimper, as will be hereinafter fully set forth.'
lnforder to enable others skilled in the art to which my invention appertains to make and use the saine, I will now proceed to describe its` construction and operation, referring to the annexed drawing, in which- Figure 1 is a front elevation, and
Figure 2, an end view of my entire machine.
Figure 3 is a transverse vertical section of the clamp and crimping-board.
A represents the, bed of my machine, from which' rise two standards, B B, connected at their upper' ends by a cross-bar, C.
The standards B B are slotted from their upper 'ends downward, for a suitable distance, and from vthe lower ends of said slots grooves extend downward on the inner sides of the standards, in which grooves the ends ot' the crimping-board D are placed.
In the slotted standards B B moves the clamp or crimper, which is composed ol' two jaws, E E', or rather, the jaws composing the crimper are attached to a cross-head, G, which moves in the slots,on the standards. Y
The jaw E, with a portion of the jaw E', are irml y bolted to the cross-head, one on each side, while the remaining or main portion of the jaw'E is hinged to the bolted portion, as shown in figs. 1 and 3.
The hinged jaw E is connected with the jaw E by means of a bolt a, which passes `through both, and a thumb-nut, b,'on the end of said bolt, clamps them together.
A rubber spring, d, is placed around the bolt a., between tlie jaws E and E', tovhold them apart as far as the thumb-nut b will permit.
At the upper ends 0fsmall standards, near the rear side of the machine, are pivoted two levers H H, connected at their front ends by a cross-bar, J, and by other bars I I with the ends of the cross-head G, by which means the crimper E Fr is lowered and raised at will.
p The crimping-board D is provided on each side with a vertical groove extending downward from near the angle of the board, and in said grooves is placed a metallic stirrup, K, of such thickness that it will project slightly beyond the surface of the crimpingboard on both sides. This stirrup is held by a pin passing through a slot in the board, as shownin fig. 3.
On the under side of the board D, near one end,
" is attached a spring, L, 'which passes through the stirrup K.
' Near the lower edge and near one end, through the crimping-board, is passed a spring-wire clamp, M, which extends almost .the entire length of the board.
The leather to be crimped is laid across the upper edge of the crimping-board, the stirrup K being rst moved up in its grooves as high as it can come. This stirrup fits so tight in 4these grooves thatv the spring L, although bearing downward upon it, cannot move it.
Vhen the crimper E E is now brought down, the points of the same .catch on the projecting stirrnp and move the same down with the leather as far as it will go, when the crimper slides over it. This causes the leather to be brought clear down smooth,v and without a wrinkle, into the angle of the crimping# board, where it always has been most dicult togetl the leather properly crimped.
Vhen the leather has been stretched by the crimper,
the wire clamp M is brought up, and holds the leather on the'board while the crimper is raised again. rlhe spring L now operates to prevent the stirrup K to slide upward.
Having thus fully described my invention,
NVbat I claim as new, and desire to secure by Letters Patent, is- 1. The grooved crimping-board D, provided with the sliding stirrnp K, spring L, and clamp M, all substantially as and for the purposes herein set forth..
2. The within-described boot-crimpen'consisting of the frame A B C, crimping-board D, with stirrup K, spring L, and clamp M, the cross'head"G, with crimper E E', levers H H, and bars I I, all constructed and arranged substantially7 as and for the purposes herein set forth.
In testimony that I claim the foregoing I have here. unto set my hand this 11th day of November, '1870.
WILLIAM POLSGROVE.
