MECHANISM FOR CUTTING AND PRICKING THE SOLES FOR BOOTS AND SHOES.
SPECIFICATION forming part of Letters Patent No. 243,069, dated June 21, 1881.
Application filed April 4, 1881. (No model.)
To all whom it may concern:
' Be it known that I, ISAAC HALL, of Boston, county of Suffolk, and State of Massachusetts, have invented a new and useful Improvementin Mechanism for Cutting and Pricking the Soles of Boots and Shoes, of which the followin g description, in connection with the accompanying drawings, is a specification.
This invention relates to an apparatus for cutting out and pricking the soles of boots and shoes; and it consists, essentially, of a "sole-cutting die and ejector therein, provided with a series of holes about its edge, combined with a series of fixed awls located to extend through the said holes, as the ejector is forced back into the die, against springs located within the said die and prick holes in the sole as-it is being cut from the side of leather, the ejector discharging the pricked sole as the die is lifted above the side of leather. The normal position of the ejector is at the level of the cutting-edge of the die and below the points of the awls.
Figure 1 is an under-side view of a sole cutting and pricking apparatus made in accordance with my invention,and Fig. 2 a longitudinal section thereof.
Referring to the drawings, A represents a sole-cutting die of usual construction, it having a cutting-edge of the form desired to give to the sole to be cut from the side of leather. The cutting-die has a back plate, b, connected therewith by means of screws a, and, as herein shown, the same screws to secure within the die the awl-holding plate 0, provided with a series of awls, 0 arranged at a uniform or proper distance from the cutting-edge of the cutting-die, and having their points extended down almost to the lower edge of the said cutting-die, as shown in Fig. 2, the lower ends of the said awls being extended into the series of holes (1 in the ejector-plate d. This ejectorplate is carried by the headed bolts or rods f g, extended upward through springs h, placed within the die, as represented in Fig. 2, the action of the said springs keeping the heads The normal position of the ejector-plate is as shown in Fig. 2; but when the die is forced down upon the side of leather to cut the sole therefrom, the ejector-plate rises or is forced upward within the die in the direction of the arrow as the cutting-edges of the die pass through the side of leather, the upper ends of rods f g at such time passing upward through holes I) b in the plate I); but as soon as the dieA is lifted from the side of leather the springs it immediately expand and move the ejector outward to discharge the sole from the die and strip it from the awls 0 for as the cutter was forced through the side of leather and. the ejector was forced up into the die the ends of the awls were permitted to come in contact with the sole-shaped piece of leather within the die and punch a series of holes through the said sole all about its edge. These holes Will receive the nails or fastenings employed to secure the outer sole upon the lasted shoe, thus doing away with the trouble of pricking the nail-holes by a hand-operated awl.
I am aware that dies capable of cutting out pieces of leather have been provided with a series of punches to punch holes through the said leather, and that an ejector has been contained within such a die; but the ejector has normally been held elevated within the die, the pieces cut out by the die accumulating therein, and to eject the said pieces the ejector, drawn into the die by springs, has been forced outward from the die by hand.
I am also aware that dies capable of cutting out pieces of leather have been provided with short awls not guided at their lower ends, and with means for casting off the punched and cut sole, consisting of stationary rods which work through holes in the die-plate and come in contact with the sole and push it out of the die after the cutting and pricking has been accomplished; but in such contrivance there just below the level of the edge of the cuttingblade and beyond the points of the awls, to shield them, the ejector yielding or moving back with the die for a distance equal to the 5 thickness of the sole being cut, and then immediately being moved outward by the spriu gs as the die is raised, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
ISAAC HALL. Witnesses L. F. CONNOR, J 0s. 1?. LIVERMORE.
