lmproved machine of this class in which the I punching operations may be performed with greater ease, rapidity, and accuracy than Machines of this type at present in use employ for the most part a perforated Wooden plate or templet, w ich is directly superposed u on and secured to the plate to be marked. e operator then with a hand-punch and ammer marks the underlying plate by a plying the handunch successively to t e several holes of t e pattern-plate and striking a blow thereon. The pattern-plate is then removed and applied to other lates to be marked, which are treated in t e same way. The plates thus marked are subsequently moved about beneath the powerounch of the machine, the point of the latter being lowered onto the centering marks previously formed by hand and the punch being then driven through the plate. The initial centering of the punch is thus dependent upon the visual accuracy of the operator in preliminarily centering the point of the punch upon the plate before the actual punching operation.

The machine of my present invention contemplates the employment of the templet in a different manner, so as-to afford apositivelyacting centering means, and, generally described, consists as to its essential features in the employment of a air of horizontal supports, the lower of which is movable bodil 1n one direction, and the upper of which 18 movable bodily over the lower in a direction atrfght angles to the movement of the latter, with means for rigidly clamping both the templet and the plate to be punched on the mper support, and a centering device adapted to engage the holes in the templet in such a manner as plate to be punched beneath the punch of the mac 'ne.

A machine embodying the invention in the best mechanical form whic I have as yet produced is illustrated in accompanying drawings, wherein Figure 1 is a perspective view of the complete machine. Fig. 2 is a top Ian view of the lower frame and supports same. 3 is a front elevational view of the machine. Fig. 4 is an. end elevational view of Fig. 3 viewed in the direction indicated by the arrow. Fig. 5 is'a detail view, partly in vertical section, of the punch-point and; guide the - Fig.

to correspondingly center the principle of mg therefor; and Fig. 6 is a side elevational view of the upper half of Fig. 5.

Referring to the drawings, 10 designates a bedlate, and 'II a skeleton' fi'ame-piec e whic rises from the rear side of the bed-plate and carries suitable journals f r a drive-shaft 12 and a punch-operating aft 13. The drive-shaft 12 has fast and loose pulleys 14 and 15, respectively, pinion 17, meshing with a \lar e loosely mounted on the punch-s aft 13 an adapted to be made fast with the latter through a suitable clutch mechanism, (indicated at 19.) The punch-shaft 13 lies within a forwardly-projecting horizontal extension of the upright frame overhanging the bedplate and actuates in the forward end of the latter the usual mechanism, (not shown,) which imparts a reciprocating motion to the punch, the perforating end ofwhich latter is shown at 21, Fig. 5. Supported above the bed-plate 10 on suitable standards 22 are a series. of parallel track-rails 23, extending forwardly and rearwardly of the bed-plate and constituting tracks for a series of grooved wheels or rollers 24, mounted in a rectangular frame 25, on the opposite sides of which latter are journaled another series of wheels or rollers 26, disposed in planes at ri ht an 16s to the planes of the rollers 24. he rol ers-26 constitute supports for a pair of track-rails 27, depending from the longitudinalside bars of gear 18 an upper rectangular frame 28. This latter frame, as best shown in Fig. 4, is a plain open rectangular frame provided along the m re;

a fly-wheel 16, and 8.-

edges of its longitudinal side bars with ledges or shoulders 28 adapted to form seats or supports for the front and rear edges of a perforated pattern-plate or templet 29 and the plate or other Work to be punched, (indi cated at 30.)

The punch-point 21 reciprocates through a suitable stationary guidin and centering device 31, Figs. 5 and 6, adjustably mounted IO in a carriage 32, adapted to be adjustably se cured to the under face of the horizontal frame extension 20, as by the screw-bolts 33, while a socket-block 34, mounted in a bracket 35, projecting forwardly from the lower por- I 5 .tion of the rear uprightof the frame in ver tical alinement with the path of movement of the punch-point, receives the latter and constitutes a local support for the plate 30 at the punching-point. The plate 30 is rigidly secured to its seat by means of suitable clamps (indicated at 36) engaging the mar gins thereof.

The templet 29 is supported and clamped in the frame 28 in a similar manner and by similar means to those already described in connection with the plate to be punched, be

ing located in said frame to one side of the latter, as clearly indicated in Fig. 1. To the bed-plate or other stationary underlying per tion of the inachine-frame is rigidly secured an upwardly and forwardly bent arm 37,

(best shown in Fig. 4,) the forward end of which overlies the templet 29 and is provided.

with a tubular guide 38, in which is recipro- 3 5 cally mounted a centering-pin 39, attached to a lever 40, this latter being pivotally mounted at its inner end through a. post 41 and link 42 on the upper side of the arm 37 and terminating at its opposite end in an op- 4o crating-handle 4.0.

43, disposed between the upper side of the arm 37 and the under side of the-lever 40 normally tends to maintain said lever and the centering-pin 39 in elevated position. The

centering-pin 39 is of a diameter to just fit the holes in the templet and has a conical lower end 39, which on entering a hole automaticallycenters the plate to bring the axis of the hole coincident with the axis of the pin Without requiring an exact centering of the pin and hole before dropping the former into the latter.

A foot-lever 44, pivoted at 45 to a station ary member of the underlying portion of the machine-frame, is connected by a thrust-rod 46 with one arm of a clutch-operating forked bell-crank lever 47, whereby the depression of the pedal-lever operates to connect the cooperating members of the clutch and impart movement to the punch.

On the forward ends of the traelerails 23 are secured posts 48, which carry in their upper ends horizontally-disposed set-screws 49, that .djustable to serve as stops, limiting the or tirardtravel of the lower frame A :compression-sprmg 25 through contact with the adjace it edge of said frame, and thus avoiding accidi it al displacement of the movable frames relatively to the bed.

In the operation of the machine the templet 29 and the plate 30 to be operated upon are rigidly secured in the frame 28 by the clamps 36, the former beneath the centeringpin 39 and the latter beneath the punchpoint 21] The operator, grasping with one hand the frame 28 or a suitable grip-handle 28* on the latter, as shown in Fig. 1, moves the frames 25 and 28 longitudinally and transversely of the bed-plate until one of the holes of. the ten'iplet lies beneath or substantially in vertical alinement with the centeringpin 39, whereupon he depresses the handle 40 with the other hand, thus causing said centeringpin to engage the templet and lock the upper and lower movable frames 28 and 25 against further movement in any direction. This determines the position of the corresponding hole in the plate 30, so that it only remains to depress the pedal-lever 44 and throw into ac tion the punch-operating mechanism, which causes the punch. to descend and perforate the plate at the desired point. The lever 40 is then raised, the frames adjusted to bring the centering pin 39 into registration with another hole of the templet, and the described operations are re )eated successively, with the result that the plate 30 is finally perforated in exact duplicate with the templet 29, whereupon the plate is readily removed by moving the upper frame 28 longitudinally out from beneath the punch. Another plate is inserted and operated upon in like manner.

The two frames, movable in directions atright angles to each other and mounted the upper upon the lower, permit a universal movement of the upper frame and of the teinplet and work carried thereby, and both frames being mounted on practically antifriction-rollers they are easily and quickly adjustable, so that the centering of the work through the templet and its centering-pin can be very easily and rapidly performed It is evident that modifications in respect to the detail construction and relative arrangement of parts in the above-described machine might be made without departing from the principle or sacrificing any of the advantages thereof, and hence the invention is not to be understood aslimited to the particular form and construction of mechanism herein illustrated and described, except to the extent clearly indicated in specific claims.
