To all whom. it may concern."

Be it known that I, ALBERT Ml ARKS, a

citizen of the United States, residing at Brooklyn, county of Kings, State of New York, have invented certain new and use-- ful Improvements in Printing-Stamps, of which the following is a full, clear, and exact description.

My invention relates to improvements in printing stamps and has for its object to produce a new and improved stamp of simple construction.

It further has for its object to provide a new and improved detent means for holding and alining the numeral Wheels of a stamp. a

It further has for its object to provide a new and improved pad-carrier for such stamps.

It further has for its object to produce a simple numbering stamp for printing numbers successively, or in duplicates, or repeating.

The following is a description of an embodiment of my invention, reference being had to the accompanying drawings, in which, l

Figure 1 is an end elevation of a stamp embodying my invention. Fig. 2 is-a side view of the same partly in section, showing the parts in operated position. Fig. 3 is a view of the stamp as shown in Fig. 2 looking upward from the line 3 8. Fig. 4 is a detail of one of the wings. Fig. .5 is a detail of the hub and detent means. Fig. 5 is a detail of the detentspring. Fig. 6 is a detail of the duplication controlling wheel, and Fig. 7 is a detail ofone of the numeral printing Wheels.

Referring more particularly to the drawings, 1-1 are the side pieces rigidly secured by screws to a top cap 2, the cap and side pieces constituting the frame or standard of the machine. From this top cap a tube 3 rises surrounding a plunger 4 to which is secured a handle 5. Between the plunger and the tube is a retracting spring 6 whose ends engage abutments 7 and 8 carried by the plunger and cap respectively so as to normally hold the plunger in elevatedposition. Connected to the lower end of the plunger and moving therewith is a U-"shaped yoke 9 in which is supported a fiXedshaft 10 which carries revoluble printingwhe'els 11. This shaft is provided with a detent the same being divided into the numeral 1 prongs corresponding in number to the revoluble printing wheels 11 and having an additional prong for the duplication con trolling wheel hereinafter referred to. These prongs engage notches 11, 11 on the inner surfaces of the numeral and duplication controlling wheels so as to aline the same.

The printing wheels carry type faces for printing the numerals from zero to nine inclusive, and also are each provided with a blank space between zero and nine type face. The notches 11 correspond to these numeral printing faces and blank spaces, those on each side of the blank space being slightly nearer to the notch opposite the blank space than the distance between the other notches so as to permit the skipping of the blank space when desired. Each numeral wheel is provided with ratchet teeth 12 corresponding, to the numeral printing faces, there being no ratchet teeth opposite the blank space. Infront of the ratchet tooth adjacent to the printing face for printing is a deep tooth or space 13 permitting the entry of the'corresponding nose of the carrying pawl.

14 is the carrying pawl having a series of carrying teeth 15, one for each numeral wheel, the tooth engaging with the first numeral wheel being longer than the others and the remainder being successively shorter. This carrying pawl is pivoted to the cap at 16 and tends to move toward the numeral wheels by reason of the spring 17. The yoke is provided with an inwardly projecting' abutment 18 which as the yoke is moved downwardly engagesthe supplemental pawl 19 so as to retract it. This abutment is formed by an inwardly turned lug integral with said yoke.

19 is a supplemental pawl carried by the main carrying pawl 14 and movable about the same pivot, which supplemental pawl is provided with three notches 20.

21 is a latch carried by the pawl 14, the nose of which can be placed in any one of the three notches 20 so as to adjust the position of the supplemental pawl. When the supplemental pawl is locked so that the nose is in the left handnotch, the stamp will print successive numbers without duplication. When the latch is in the right hand notch (Fig. 2) the pawl 14 is thrown out of action so that the stamp will repeat the 7 same number indefinitely. When the pawl is in the central notch (Fig. 2) the stamp will duplicate any number printed. Thislast action is due to the presence of a duplication controlling wheel 22 which is provided with four shallow ratchet teeth and four deep ratchet teeth or notches 23, their being a detent tooth 11 corresponding to each ratchet tooth thereon. When the supplemental pawl 19 is adjusted for duplication, the nose of the latch 21 being in the "central notch 20, the carrying pawl 14 is held out of action when the nose of the supplemental pawl engages one of the shallow ratchet teeth, but is permitted to act when that nose enters one of the deep notches 23. The result is that thercarrying pawl, 14 acts only on every other movement of the printingmechanism.

7 Pivoted to the yoke 9 are two wings 24 and 25. The wing 25 carries a cradle 26 for the inking pad 27. This cradle is pivoted to the wing at 28. It carries an upwardly projecting member 29 which, when the handle of the stamp is in elevated position engages the edges 30 of the yoke so as to force the inking pad against the type faces. The

wing 25 is provided with a spring 31 which bears against this upwardly projecting member so as to tend to move the pad away from the printing faces when wing 25 moves outward. The cradle is also provided with a spring 32 which prevents the cradle from tipping down too far and yet yields so as to snap by the inner face of the wing, thus permitting the cradle to be inverted for the purpose of' inking or replacing the pad. The

cradle is provided with upwardly turned side lugs 33 which, as the wing 25 moves toward the body of the stamp engages the surfaces 34 at the lower end of-the yoke, thus holding the pad away from the type faces until the wing 25 is approaching vertical position. The wings 25 have on their lower ends cam surfaces 35 and the standard or frame has inwardly turned lugs 36 which lie in the paths of these cams. When the parts are in the position shown in Fig. 1 these lugs 36 being. engaged with cam surfaces 37 on the downward stroke of the plunger force the wings 24 and 25 outwardly until they contact with the paper, which then acts to force them still farther downwardly into the position shown in Fig. 2. These lugs 36 and cam faces 35 are described and claimed in a companion application Serial No. 6,715, filed Feb. 8, 1915. The cap member 2 is provided with cam surfaces 37 which er gage with the faces 38 at the upper ends of the wings as theyoke 9 rises and forces the wings into vertical position, overcoming the action of the spring 31.

The operation of the device is evident from the above description.

When the plunger is depressed the wings open and the inking pad is withdrawn and 7 As wi art, my invention permits of various modifications without departing from the spirit thereof or the scope of the appended claims.
