UNITED STATES GEORGE G. CONVERSE, OF SPENCER, ASS IGNOR TO ABNER WHEELOO K, OF
' CHARLTON, MASSACHUSETTS. I
IMPROVEMENT IN MACI-IINES FOR PRICKING LEATHER.
Specification forming part of Letters Patent No. 135.969, dated February 18, 1873.
To all whom it may concern: I
Be it known that I, Gnoaen O. CONVERSE, of Spencer, in the county of Worcester and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Combined Boot-Leg and Welt Pricking Machines; and I do hereby declare that the followin g is a full, clear, and exact description of the same, reference being had to the accompanying drawing which forms a part of this specification, and in which- Figure 1 represents a front view. Fig. 2 represents an end view, the lower portion being shown broken off. Fig. 3 represents a vertical central section on line A B, Fig.1. Fig. 4 represents a perspective View of the machine, and Fig. 5 represents a top or plan view of the machine.
To enable others skilled in the art to which myinvention belongs to make and use the same, I will proceed to describe it in detail.-
In the drawing the part marked A is the table, secured to and supported upon the top of the frame 13. Upon the rear part of the table A are two gage-plates, a b, the former being perforated with a series of small holes, 0. Above the gage-plates a b is supported, upon the front ends of spring-arms O, a perforated .presser-plate, 0, upon the top of which is secured a gage-plate, f. The rear ends of spring-arms O are fastened to the lowerside of the cross-bar D, which is secured to the end pieces E, the latter being pivoted at g to the rear ends of arms F, fastened to the rear upper corner of frame 13. To the front ends of end-pieces E is secured ahead-plate, G, from the lower edge of which project a series of small perforating punches or awls,'h, said awls beingheld in placeby small set-screws 2;
Each end of head-plate G is connected to the crossbar H by a connecting-rod, 3. .The ends center to the upper edge of theheadplate G, as shown at 6. To the inner sides of the arms F are attached levers K, by means of journals N. The rear ends of levers K are provided with cams 7, which are acted upon by cams 8 on the lower sides of the rear ends of the end pieces E, when headpiece G is depressed. To
the front ends of levers K is fastened cross piece L, provided in this instance with three points, 9, which project up from its upper side, and holes are made in table A and gageplate a, through which said points 9 pass when the rear ends of levers K are depressed. Cross-piece L is drawn down by means of springs 10 when headpiece G is elevated.
Operation. The operation is as follows when my machine is used to facilitate the siding of boot legs: The parts of the machine being in position, as shown in Figs 1, 3, and 4, the operator places one bar, 11, of his clamp, upon project a little above the upper surface of the presser-plate e, the latter being slotted out, as shown at 11. The operator now places the welt upon the top of the presser-plate e, the
pieces of leather which have been pricked, and then clamps both bars firmly together, afterwhioh 'head-piece G is allowed to rise, when the awls h are withdrawn from the pieces of leather which have-been perforated preparatory to beingremoved to be sided by hand. The gage-plate a serves as a guide-in placing the clamp in position. In lieu of sprin g5, guidepins 4 may be headed on top and held down by means of spiral springs arranged around them in head-plate G, the lower ends of the springs resting on the strippingplate J. The presser plate 0 may be made in sections. and not extend from end to end of the machine; and, if preferred, one thick gage-plate may be made to answer the purpose of gage-plates b and f when the gage-platefis made in sections. In this case, however, the thick gageplate should be slotted or cut out to allow the arm 0 to drop sufficiently low down to bring the sec tions of the presser-plate a down upon the points 9, the same as now shown in the draw mg.
Having described my improvements in com bined boot-leg and welt pricking machines, what I claim therein as new and ofmyinvenself-adjusting cross-piece L, provided with holding-points 9, substantially as and for the purposes set forth.
4. The combination, with the levers K and end-pieces E, of cams 7 and 8, substantially as and for the purposes set forth.
5. The combination, with the table A, head plate G, and hinged end pieces E, of perforatingawls h, stripper-plate J, perforated presser-plate e, and gage-plates a, b, and f, substantially as and for the purposes set forth.
GEORGE (J. CONVERSE.
