STENCIL-CHARACTER PUNCH-MACHINE.

SPECIFICATION forming part of Letters Patent No. 544,169, dated August 6, 1895.

Appli filed March '7, 1895. Serial No. 540,805- (No model.)

To all whom it may concern.

Be it known that I, STEPHEN D. HARTOG, Jr., a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Stencil-Character Punch-Machines, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in stencil-character punch-machines; and it consists in the novel arrangement and combination of parts more fully set forth in the specification, and pointed out in the claims.

In the drawings, Figure 1 is atop plan View of the machine. Fig. 2 is a bottom plan view of the same. Fig. 3 is a middle vertical section on the line 00 ac of Fig. 1. Fig. 4c is an enlarged detail viewed from the inner side of the feed-disk and the pawl operating the same. Fig. 5 is a detail plan view showing the manner of attaching the-plates carrying the punch-characters 'to the revolving annular disk carrying the same. Fig. 6 is an enlarged detail view taken from the side of the operating-lever, showing the arrangement of the cams which control the feed-pawl and guide-plate carrying the same; and Fig. 7 is a detail section taken on the line yy of Fig. 3.

The present invention is an improvement on the mechanical device described in my pending application, Serial No. 535,456, filed January 19, 1895, for stencil-character punchmachines, being materially modified as to details of construction, the object of the invention being to produce a stencil-character punch-machine which will be compact, simple, durable, and light, be easily manipulated, and present certain and other advantages resulting from its inherent construction.

' In detail it may be described as follows:

' ing-table 5, whose forward curved edge carries a series of characters 6. Through an openingin the middle of the base is a sleeve 7, rotatable within the opening, the lower end of which sleeve carries a pinion 8. To the sleeve 7 and above the base 1 is secured a circular plate 9, along whose outer edge are disposed a series of dies, and there is also secured to said sleeve an annular disk 10, to which are rivetedor otherwisesecured a series of radially-disposed segmental plates 11 inclined upwardly from said disk, and whose free ends carry each a punch character corresponding to the die immediately below it on the plate 9, the punch characters and dies of course corresponding to the characters 6 indicated along the curved edge of the bedplate 5.

Pivoted under the base 1 at a suitable distance from the sleeve 7 is a swinging lever12 whose short arm carries a toothed segmental are 13 meshing with the pinion 8, so that the series of punches and cooperating dies may be simultaneously rotated to any desired position. The handle 14 of the lever 12 carries an index 15 to designate the character which it is desired to punch out, as subsequently to be explained. To properly'retain the handle 14: and the index carried by it opposite the necessary characters designated on the bedplate, and thus insure that the proper character is punched by the machine,I provide a retaining-lever 16, which is pivoted to the lugs 17 carried by the handle opposite to the index, the short arm of said retaining-lever carrying a pin 18 passing through an opening in thelever 12, the free end of the pin being adapted to enter one of a series of depressions 19 disposed circularly along the bottom of the bed-plate 5 to correspond with the path described by said pin. The said pin is held in its particular depression (there being one depression for each character and of course arranged along the same radial line with its character) by a yielding spring 20 interposed between the free end of the lever 16 and handle 14, and having one end secured to the lever and its free end pressing against the under surface of the handle 14. (See Fig. 3.) To release the pin from its depression the lever 16 is simply tripped toward the handle 14 against the resilient action of the spring, when the opposite end carrying the pin 18 will trip the latter out of engagement with its depression, leaving the lever 12 again free to sweep around and rotate the series of punches and dies under the control of the operator.

The rotating die-plate 9 and punch-carrying plates 11 are housed within a superposed protecting-plate, having secured thereto a spider 21, having ribs 22, by which it is secured or bolted to the base 1. Passed rigidly through a central opening of the spider and extending .through the sleeve 7 is a pin 23, about which the sleeve 7 rotates, the base of the pin passing through a bottom plate 24, whose inner surface forms a support for the pinion S, a collar 24 forming a part of the pin 23, preventing any upward movement or displacement of the sleeve 7 and the parts carried thereby.

The upper face of the die-plate 9 and that of the bed-plate 5 are on a level, so that the sheet of paper 25 fed under the punch may lie on a perfectly plane surface. Interposed between the die-plate and the series of punchplates is a stationary stripper-plate 26, secured preferably at opposite sides to the bedplate 5, said stripper-plate having an opening for the accommodation of the punches, the function of said stripper-plate, of course, being to prevent the paper, after a character has been puhched therefrom, to be carried up by the punches upon their return to their normal position when released from their depression position by the operating-lever which controls them.

I will now describe the mechanism for operating the plates which carry the punches, and the mechanism for feeding and guiding the paper to be operated upon. Formed integrally with the spider 21, and superposed over the series of punches and dies revolving beneath the spider, is a head 27, through which loosely passes a plunger 28, normally resting and adapted to slide over the operating ends of the punch-plates 11, and projecting a suitable distance above the surface of the head. Pivoted between suitable lugs 29, carried by the head, is an operating-lever 30, whose lower end adjacent to the pivotal point carries a heel 31, adapted to co-operate with the plunger and depress the same against the punch-plates. The lever is retracted to its normal position by a spring 32 secured at one end thereto and having its opposite end secured to a hook 33, carried by the cap-plate 34 of the pin 23. To prevent the lever 30 from being carried over too far by the retracting action of the spring 32, I provide said lever with a toe 35, adapted to strike a projecting finger 36, carried by the head 27, by which the lever is kept normally in a position indicated in Fig. 3. As the lever 30 is depressed the heel 31 forces the plunger against the particular puneh-plate brought under it, (the character carried by the particular punchplate being indicated by the index 15,) the punch passing through the opening in the stripper-plate cutting out (through the cooperation of its corresponding die) the stencil character from'the paper 25 fed under it, when, after the cutting of one character from the paper, the latter is fed to a position to be operated upon by the next succeeding punch.

The mechanism which feeds the paper is as follows: WVithin a suitable guideway or cavity 37, formed between the side wall of the head 27 and a plate 38, secured thereto, is adapted to move freely up and down a guideplate 39, having an upper terminal rounded shoulder 40. This shoulder is adapted to be struck by a lower cam 41, carried by the lever 30 during the downward stroke of the latter, the engagement between said shoulder and cam 41 taking place before the wheel 31 actually engages the plunger 23. Pivoted within the shoulder 40, and swinging in a plane at right angles to the plate 39, is a pawl 42, having an extension 43, whose terminal right-angular projecting end 44 is adapted to come in contact with the upper cam 45, carried by the lever 30. The pivoted pawl 42 engages with the teeth of a ratchet-wheel 46,

shaft of the feed-disk 47, which latter is mounted at the end of the short arm of a lever 48, pivoted at 49 to the front of the head 27 of the spider. The pawl 42 is kept in engagement with the ratchet 46, or rather the individual teeth thereof, by the free end of a spring-plate 50, whose upper end is secured to the guide-plate 39. The feed-disk 47 is kept firmly against the paper fed by it by one end of the spring 51, coiled about an arm 52 projecting from the side of the head 27, the -inner, end of the said coiled spring bearing against the side wall of the said head. The free outer projecting end of the coiled spring engages a depression 53 (see Fig. 4) in the lever-arm 48. By this arrangement and by the resilient action of the coiled spring 51 it is obvious that the lever 48 will always be pressed upward, insuring a corresponding downward pressure of the feed-disk 47, carried at the opposite end or short arm of the lever against the paper sheet passing under it. Of course to first introduce a sheet of paper under the feed-disk the latter is slightly tripped upward by tripping downwardly the free end of the lever 48. An antifrictionroller 54, mounted on the bed-plate 5, co-opcrates with the feed-disk to facilitate the passage of the paper sheet between them. As the lever 30 is depressed,the cam 41 will drive the guide-plate 39 and parts carried thereby the next succeeding tooth of the ratchet 46. A further depression of the lever forces down the plunger 28 and allows the pawl 42-to seize an additional tooth of the ratchet. \Vhen the lever 30 returns to its normal position under the action of the spring 32, the cam 45 engages the projection 44 of the pawl extension, drawing the pawl and guide-plate 39 upwardly, by which action the ratchet 46 and forming a permanent part of or secured to the downward, allowing the pawl 42 to engage disk 47, carrying the same, are rotated an extent of two teeth, thus feeding and shifting the paper into position for the next character that it may be desirable to cut in the paper.

It is obvious from the construction just described that upon only a partial depression of the lever 30-that is to say, only so much depression as will allow the pawl to engage but one tooth on the ratchet, but still leave the heel of the operating-lever out of contact with the plunger-the ratchet and feeddisk secured thereto may be rotated any number of times without actually operating .the plunger, so that under such circumstances the paper may be fed forward any desirable number of spaces without being cut by the punches. In this manner the spacing between the various characters out in the paper may be made variable.

To accommodate variable widths of sheets and at the same time guide the same While being fed under the punches, I providean adjustable transverse guide-bar 55, having an overlapping edge 56, under which the edge of the paper sheet passes, the said bar being adjustable along the bed-plate in a slot 57, along which the bar is shifted to accommodate variable widths of paper, the bar being held within the slot by the resilient expanding action of the members of the fork 58 forming a part of the bar. A knob 59 is provided, by which the parts can be grasped by the operator.

The pun'chplates 11 are inclined upwardly, sothat when depressed under the action of the plunger to drive the punches into their corresponding dies, the said punches may enter the dies in a direction as nearly at right angles to the plane of the die-plate as possible, and thus reduce the binding between the parts to a minimum.

Having described my invention, what I claim is- 1. In a stencil-character punch machine, a suitable base, an operating table extending therefrom, a series of characters disposed about the operating table, a common axis mounted on said base, a rotating die plate carried by the axis and having its upper surface substantially on a plane with the operatingtable, a pinion carried by the axis of the die plate, a swinging lever having a terminal toothed arc controlling said pinion, an index controlled by the swinging lever and co-operating with the index-characters, a series of punches for the dies of the die plate, a suitable plunger for said punches carried by the stationary part of the machine, an operating lever for controlling the plunger, and a suitable feeding device mounted above the operating table, substantially as set forth.

2. A stencil-character punch machine comprising a suitable base, a series of rotatable punches and corresponding dies, a plunger carried by the machine and adapted to co-operate with the series of punches, an operating lever for said plunger, suitable feed mechanism controlled by the operating lever, and suitable devices between the feed mechanism and operating lever for actuating the former in advance of the plunger, substantially as set forth.

3. In a stencil-character punch machine, an operating lever pivotally mounted on the machine frame, a guide plate movable in said frame in proximity to the lever, a cam on said lever for operating the guide plate in one direction, a pawl pivoted to said guide plate, an extension on said pawl, a second cam on said lever 'for operating the pawl and guide plate simultaneously in the opposite direction, a spring plate carried by the guide plate co-operating with the pawl, and a suitable feed disk controlled by the pawl, substantially as set forth.

4:. In a stencil-character punch machine, a suitable bed plate, a slotted guide-way on said plate, a transverse guide bar on said bed plate, an overlapping edge carried by the same, a fork forming a part of or secured to the guide bar and inserted in the guide-Way of the bed plate, and suitable feed mechanism co-operating with said guide bar, substantially as set forth.

5. In a stencil-character punch machine, a suitable base, a spider carried by the same and extendinga suitable distance above said base plate, a pin rigidly passed throughthe spider and base, a sleeve loosely embracing the pin and passing through the base, a collar on the pin above the sleeve for limiting the movement of the sleeve in one direction, a die plate and corresponding punch carrying plates secured to the sleeve, a pinion carried by the lower end of the sleeve,a plate for the support of said pinion secured to the lower or under surface of the base, and suitable mechanism for rotating the pinion, sleeve and parts carried thereby, substantially as set forth.
