PUNCHING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 349,072, dated September 14,7 1886-.

Application led April '29, 1886. Serial No. 100,513. (No model.)

To all whom it may concern.-

Be it known that l, LA FAYETTE XVILDER MUTH, a citizen of the United States, residing at Lancaster, in the county of Fairfield and State of Ohio, have invented certain new and useful Improvements in Punchilig-lvlachines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in punching-machines for making holesin wood or other material.

The object of my invention is to provide a machine which will punch a series of holes of uniform distances apart at one and the same operation, and is designed more especially for punching holesin bed-bottom slats for theinsertion of the springs.

Myinvention consists of abarprovided with a series of punches mountedin suitable guides or ways on a bench or other suitable support, and operated by a compound lever, which will depress the punch-carrying bar throughout its entire length,as will more fully appear.

Figure l is a view in perspective of my device. Fig. 2 is a side elevation. Fig. 3 is a detached portion of the guide-har and 'the straps for holding the saine on the trestle.

A indicates the top of the trestle or bench, having the legs or other suitable supports, B, said trestle being bracedin any desired man'- ner so as to form a rigid support for the operating parts of the machine.

C are clips or metalstraps secured to theV sides of the top of the trestle, said straps being extended a short distance above the top A and bent at right angles, to which the bar C'is attached. The bar G is suspended far enough above the top A to allow the article to be punched to be placed between it and the upper surface of the top A. The bar C is provided with a series of apertures, c, which register vwith the punches in the bar I, and also with the apertures a, formed through the top A,said apertures being for the passage of the chips made by the punches in their passage through the slat. The bar C' not only serves as aguide for the punches, but also as a stop for the slat when the punches are being withdrawn from the same.

D is a metal plate secured to the top of the trestle, said plate being provided with apercountersunk on the upper side, so that if the punches should bend a little to one side while passing through the Slat they will strike the beveled or countersunk. portion, which will cause them to move over toward the center of the aperture.

D is a bar secured to the top piece,A, to the lower end of which is pivoted the operatinglever E, said lever being attached to the inner ends of the compound levers F F by means of the links or bars G,the outer endsof the compound levers F F being pivotally secured to the bars H, which in turn are secured to the top piece, A. The levers F are secured to the punch-carrying bar Iby bars or links K, and by which means the punch-carrying bar is raised and lowered when the lever E is operated.

In operaton the machine is fastened secnrely to the door. The outer end of the lever E is raised to its highest point. The operator then shoves a slat in between the guide-plate C and the plate D their full length. The points of the punches are now in the holes in the guide plate or bar O', which will keep them all in a line. rIhe outer end of the lever E is now depressed. .This will draw down the punch-carrying bar and force the punches through the slat, the points of the punches entering the holes b in the plate D and the holes a in the top A. The upward movement of the punches through the guide-bar C serves to straighten them, provided they have been bent by striking a knot or other hard substance in their passage through the slat. The slat when Apunched is pushed out at the other end of the machine by the insertion of another slat at the lever end, so that one person is enabled to work the machine rapidly. By this construction of machine I am enabled to make the perforations in the slats of uniform distances apart, so that the bed-springs can be applied readily thereto by any unskilled person; and, furthermore, the work can be more rapidly done than heretofore, and the arrangement of the lever enables the work to be readily done by ahoy.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s
