SPECIFICATION forming part of Letters Patent No. 632,136, dated August 29, 1899.

Application filed December 14, 1897-. Serial No. 661,826. (No model.)

To all whom it may concern:

Be it known that I, STUART B. MOORE, of New York, (Brooklyn,) in the county of Kings and State of New York, have invented a new and Improved Stenciling-Machine, of which the followingis afull, clear, and exact description.

My invention relates to a device for punching sheets of paper or similar material to be used for stencils; and it consists of certain devices which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a longitudinal sectional elevation of the machine. Fig. 2 is a plan View. Fig. 3 is a longitudinal sectional elevation, upon a larger scale, of the two rotating disks with the punches and plunger for operating the same. Fig. 4 is a side elevation of the paper-feeding mechanism. Fig. 5 is a crosssectional elevation of the upper feed-wheel and its operating mechanism. Fig. 6 is abottom plan view, on alarger scale, of the upper plate D, showing the punches. Fig. 7 is a longitudinal sectional elevation taken through the central portion of the mechanism, showing the reciprocating block which carries the plates and the means for reciprocating them; and Fig. 8 is a plan view of the same.

My invention is designed for punching sheets of paper to form stencils which are intended for temporary use only; but the same construction, if built of sufficient strength, may be used for punching stencils through sheets of metal.

In shipping goods itis always desirable that the address shall be put on by stencils, if such a thing is possible. To have stencils made in metal for each shipment of goods would, however, be too costly. It is therefore desirable to be able to make these stencils cheaply from paper which will answer sufficiently for addressing a large number of packages and which will cost but a trifle.

The machine is mounted upon a frame consisting of a base A and a bridge, which is formed in four arms-'the rear arm 13, the side arms B, and the forwardly-extending arm B the latter carrying the plunger, the operating-lever, and the paper-feeding mechanism.

Upon or within the base A is formed a guideway C within which is mounted to slide a block 0. This block has teeth formed upon one edge thereof comprising a rack, as clearly shown in Fig. 8. This rack is engaged by the segmental gear K, the same being formed as a part of or attached to the lever K, said lever and the gear being pivoted at upon the base. By throwing the lever K to one side or the other the block 0 is caused to reciprocate within the guide. A pin or standard 0 is mounted upon the block 0 and forms the pivot for the disks D and D, which carry the punches and dies for forming the letters. These two disks are rigidly secured to each other, so as to revolve together. The upper disk D has a series of holes corresponding in number with the characters the machine is intended to produce. Two rows of punches .E and E are shown, the former being farther from the center and intended for letters of a larger size than those upon the inner row. The two rows may be used for different characters in one complete set or to make two complete sets of different sizes. The holes which containthe punches are covered at top and bottom by thin plates d and d, as shown in detail in Fig. 3.

The punching-die is mounted upon the lower end of the punch-bars E and E. The plates cl and d have holes therethrough corresponding in outline to the cross-section of these punch-bars. The punch-bars are supported by springs of any convenient form, which will normally hold them raised, so as to leave opportunity for the paper J to be inserted between the two disks. As shown in the drawings,this consists of the spiral springs E surrounding the punch-bars and-within holes in the disk D, said springs engaging the lower plate cl, and a collar E ,which is formed upon or attached to the bars E and E. The disk D has dies D formed therein exactly registering with the punching-dies upon the punch-bars E and E. If the paper which is to be used in forming the stencil be inserted between the two disks and one of the punches is forced down, its die will enter the die in the disk D and cut out a corresponding portion of the paper. These punch-bars are engaged and forced downward by the means hereinafter described. The upper ends of the punch-bars are provided with side-extending notches e and c, which leaves narrow ledges e at the upper end of the punch-bars. These notches extend toward the opposite row of punch-barsthat is, the notches upon the two rows face toward each other. It will be noticed that the notch e in the punch-bar E is of greater width than the corresponding notch e in the punch-bar E. This is to provide a certain amount of slack motion of the plunger P when the same is moved down, and thus to provide for a greater feed of the paper J before the punch is brought into operation.

To the upper side of the arm 13 of the bridge is pivoted at H the operating-lever H. This is normally held up bya spiral spring h. To this lever is pivoted a plunger P, which is mounted to slide upon the arm'B of the bridge and at its lower end has side-extending notches p and 19, facing, respectively, toward the punch-bars E and E. This leaves a narnow ledge or flange P, which is adapted to engage the punch-bars within the notches formed therein. WVith the disks placed in one position the punch-bars E will be in position to be engaged with the flange P at the bottom of the plunger. If the block C, carrying the disks, be reciprocated to the opposite position, it will carry the disk to one side a sufficient amount to cause the other punch-bar to be engaged with the opposite side of the plunger. By forcing the lever H downward the plunger will engage the punch which is immediately below it to punch out a letter in the paper. The flange P will engage the flange 8 upon the punch-bar and lift the punch-bar, thus positively freeing it from the paper.

The disks are turned to the proper position by any convenient means. I have, however, shown a plate L, fastened to the axis of the disks and lying above the bridge 13. This plate is provided with a knob or handle L for convenient engagement and has the characters of the disks laid out upon its surface in corresponding position. The under side of the disk is provided with corresponding notches located so as to successively engage the springbar L and thus to hold the disks in proper position after being revolved. This springbar L will readily yield when the disks are revolved by hand.

The feed of the paper is secured by means of the feed-wheels I and I, the latter journaled upon the frame beneath the paper and the former upon a downward extension B of the arm 13 These feed-wheels are constructed as shown in detail in Figs. 4 and 5. The feed-wheel I is provided with an internal ratchet I and the pinion G, which is mounted upon the same shaft as the feedwheel, but free to rotate independently thereof, is provided with a pawl G adapted to engage said ratchet. The pinion G is rotated by the engagement of a rack-bar G therewith.

This rack-bar is connected to the lever H and works in guides upon the arm B Its lower end is provided with a section of teeth g and just above this with a narrow space g, followed by another toothed section 9 and narrow space g The throw of the operatinglever II will be less when the plunger engages the inner set of punch-bars than when it engages the outer set, by reason of the fact that there is less lost motion. In consequence of this the pinion G, and consequently the feedwheel I, will be rotated during the engagement of the toothed section 9 and the punching operation be secured during the downward movement, in which the blank space is in engagement with the pinion G. The increased feeding movement required for the outer set of punch-bars will be secured by an additional feeding movement caused by the engagement of the toothed section The feeding movement of the paper is thus automatically increased for the outer set of punch-bars over that used for the inner set.

To bind the disks securely to the bridge formed by the arms B and E the upper disk D is provided with a concentric circular flange F,

which is T-shaped at its upper edge. Hooks f and ledges f are formed beneath the bridge and supported therefrom, which are adapted to engage the flange and support it when the disks are in either position. When the disks are in one position, the flange is engaged by one pair and when in the other position by the other pair. The parts are thus held against springing apart by the strain of the punching operation.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
