Description
SOLYMAN MFiItItIGK, OF SPRINGFIELD, MASSACHUSETTS.
IMPROVEMENT IN REVOLVlNG SPRING-PUNCHES.'
Specification forming part of Letters Patent No. 5,435, dated February 8, 18218.
To all whom it may concern:
Be it known that I, SoLYMnN Mannion, of Springfield, in the county of Hampden and State of Massachusetts, have invented a new and useful Improvement in the Revolving Spring-Punch on which Letters Patent No. 636 of United States of America were granted to me on the 17th day of March of the year 1838; and I do hereby declare that the same is fully described and represented iu the following specification and accompanying drawings, letters, gures. and references thereof'.
Ofsaid drawings, Figure 1 denotes a side elevation of my improved punch. Fig. 2 is a top view of it. Fig. 3 is avertical and transverse section taken through the series of revolving punches. Fig. el. is a view of the under side of the holding-jaws and the rotating series ot' punches.
In said figures, A denotes vthe bed-lever of the punches; B, the punch-lever, or that which supports or carries the series of rotating punches F F F F, which are sustained and revolve between springjaws D D.
I is the bed or block, of copper or other proper material, in conjunction withv which the lower punch acts during the operation of punching a hole in a piece of leather.
Eis the cylinder to which the several punches are fastened. In the instrument described in Y the schedule of the Letters Patent hereinabove mentioned the spring jaws or sides D D of the punclrlever were provided with curved recesses 0r circular catches, as seen 'at Gr G in Fig. 3 of the drawings of said Letters Patent. The said recesses were for the pirpose of clasping and holding the lower punch, and ofcourse all the others, stationary while beingused. In practice it is found that they do not answer the purpose intended..
By caret'ul inspection ofthe manner in which the punch is made to operate on a piece of leather placed on the bed I it will be observed, when it enters and while it is passingthrough the leather, that, as it moves in the are of a circle and is in form a straight frustrum of a cone, aforce will be exerted against it in a direction which causes it to move a little outward or toward the contiguous end of the lever A. This force, constantly acting whenever the instrument is used, soon wears the recesses G G in such manner as to render it very difttcult to punch a hole through any piece of leather or other substance in the manner re= quired. The instrument, when so made, has been found to get out of order in a very short time and to such extent as to be of little value. In order to remedy the said defect I dispense with the curved recesses, and in lieu thereof I malte a right-angular notch, a, in each springjaw, which notch IA make to it one of two projections or right-angular shoulders, l) b, made on the sides ot' the punch, the form of said notches and said shoulders and their positions being represented in Fig. 4. The peculiar manner in which they operate together renders itimpossible for the lower punch to move laterally toward the adjacent extremity of the lever A. Each punch of the series should be fitted with one or two righ t-angular shoulders. The notches a a are made in cam-proiections o c, formed respectively on the spring-jaws, as seen in Fig. 4.
For the purpose of etfectually discharging the little circles or cylinders of material separated from any article by the cutters, and which pass through the cutters and into the interior or space K of the cylinder E, I place in said space K a cone, cl. or any proper equivalent inclined surface, which I arrange with respect to the discharging-mouths of the punches as seen in Fig. 3, or so that after the pieces of leather or other material have passed out of the punches they may be forced against the cone and by it directed laterally and out'of the space K. Without some such contrivance the space K is very liable to become filled or choked by the pieces which Iare cut away lrom the leather or other :material by the punches.
What I claim as my invention isl. The manner or mode in which I etfectually preventJ the punches from improperly moving while in act of cutting-viz., by one or more right'angular notches, one or more right-angular shoulders, in combination with or applied to them and the spring-jaws, substantially as specified.
2. The cone al as arranged with respect to the punches and combined with the space K of the cylinder E, substantially in manner and for the purpose as above specified.
In testimony whereof I have hereto set my signature this 17th day of May, A. D. 1847.
SOLYMAN MERRIOK.
