IMPROVEMENT IN MACHINES FOR PUNCHI NG LEATHER.
Specification forming part of Letters Patent No. 131,330, dated September 17, 1872.
To all whom it may concern:
Be it known that we, THOMAS BURKITT, of Brooklyn,NewYORK, and JOHN K. KRIEG, of New York city, in the State of New York, have invented a certain Improvement in Means for Punching Leather, of which the following is a specification:
The object of the invention is to punch lines of small holes for ornamental or other purposes. Heretofore these have been formed by expensive dies, constructed for the purpose, and allowing no variation in the distances apart. We adapt suitable tools to a common sewing machine, and by varying the feed the distances of the holes apart may be varied at will. We provide a punch in place of the needle, and a carefully-fitted female die corresponding to the punch, in place of the throatplate. At a proper distance above the female die we place a rigid guide, which so aids in maintaining the proper position of the punch that it is certain to descend accurately into the closely-fitted female die below. The operation may be as rapid as in ordinary sewing.
The following is a description of what we consider the best means of carrying out the invention. The accompanying drawing forms a part of this specification.
Figure lis a front view; and Fig. 2 is a section on the line S S in Fig. 1, showing the work both above and below the material to be treated. Fig. 2 shows, also,a section through the lower part of the guide, instead of simply showing it in elevation. Fig. 3 is a plan view of the lower parts alone.
Similar letters of reference indicate like parts in all the figures.
The drawing represents the novel parts with so much of the ordinary parts as is necessary to indicate their relation thereto.
A is the cloth-plate; B, the wheel-feed; D, the resser-wheel; E, the needle-bar; and A, the rigid head, which guides the needle-bar.
All these parts are constructed and arranged according to a familiar plan in sewing-machine work. The machine is adapted to be used with the ordinary throat-plate and ordinary needle in sewing in the ordinary manner.
When it is desired to punch leather the needle and throat-plate are removed, and in the place of the needle is introduced a punch, M. In place of the throat-plate is introduced a female die, N, and upon the side of the head A is firmly bolted a stout guide-bar, P. The latter is formed with a conical hole in the foot part at the base, as represented. This hole guides the punch in its descent. The guide P p is preferably capable of being adjusted slightly upward and downward to allow for different thicknesses of leather. It is well to have it always as low as the thickness of the leather will allow. In case the lowerend of the punch rises up, through and entirely clear of it, the conical form of the hole 12 will guide it accurately into the right position in its descent. A suflicient amount of vertical adjustment of the guide P p may be allowed by simply making the holes which receive the bolts G a little elongated.
. We propose to make a portion of the fixed work below conveniently removable, to allow the small pieces of leather removed by the punch to free .themselves more readily from the die N and the work below it; but this may not be essential. We have punched very successfully with an ordinary sewing-machine, factory size, fitted as here described, without any alteration of the parts further than the substitutions here described and the addition of the guide P 1).
We claim as our invention- The reciprocating punch M, the female die N, and proper feeding mechanism for moving the material at each reciprocation, in combination with each other and with the guide I? p, or its equivalent, adapted to support and guide the punch accurately in its presentation to the die, as herein'specified.
In testimony whereof we have hereunto set our hands this 9th day of April, 1872, in the presence of two subscribing witnesses.
THOS. BURKITT. JOHN K. KRIEG. Witnesses:
WM. 0. DEY, ARNOLD HOB-MANN.
