STAMP.

Specification of Letters Patent.

Patented July 6,1915.

Application filed February 8, 1915. Serial No. 6,715.

To all whom it may concern Be i known that I, ALBERT MARKS, a

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

My invention relates to improvements in hand stamps and has for its object to produce a new and improved stamp.

It further has for its object-to produce a stamp having one or more wings, which, as the stamp is operated, are thrown outward by a cam action between the wing and the main frame or standard.

It further has for its object to produce a stamp having a flat printing surface and an inking pad which is withdrawn therefrom and applied thereto by a combination of vertical and oscillating movements.

It further has for its object to provide a new means for securing the pad in place.

It further has for its object to provide a new guiding means for the printing memher.

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

Figure 1 is a side elevation of a hand stamp embodying my invention. Fig. 2 is a view, partly in section, of the stamp in operated position. Fig. 3 is a view of certain internal details. Fig. 4 is an upward view of the stamp with the parts in the positions shown in Fig. 2. Fig. 5 is a perspective detail of the pad-carrying means. Fig. 6 is a perspective view of a guiding means. Fig. 7 is a perspective view of one of the side frames.

Referring more particularly to the draw ings, 1, 1 are 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 abutme'nts 7 and 8 carried by.

the plunger, and cap respectively so as to normally hold the plunger in elevated position. Connected to the lower end of the plunger and moving therewith 'is a U- shaped yoke 9 in which is a fixed shaft 10 which carries revoluble printing wheels 11. The lower end of the yoke carries a cross plate 12 on which is engraved type for printing a word, such as Paid. The printing wheels carry type for printing a date. To the yoke are connected movably pivoted wings 13, one of which carries an inking pad 14. The side pieces 1, 1 carry in wardly projecting lugs 15 with which cam surfaces 16 on the wings engage during the first part of the downward movement of the plunger. This engagement results in throwing the wings outward somewhat, after which the cam surfaces 16 of the wings engage the paper to be printed on and are thereby forced into the positions shown in Fig. 2. The presence of the lugs 15 relieves the paper from the first thrust, which is the hardest, and prevents injury thereto. On account of the presence of the word-printing plate 12, a, wide printing surface is presented, such that the inking pad 14, carried by one of the wings 13, cannot well be applied and Withdrawn by a movement in a'true are. In order to easily apply and remove the pad from the type surfaces I'provide means for permitting it to move downwardly during the first movement of operation of the stamp and then swing it away with a movement in an arc, and for securing the reverse movements. in the return movements of the parts. This means consists in providing a pad-carrier or cradle 17 having elongated slots 18 through which passes a rod 19 secured to the wing 18. The upper end of the pad-carrier is provided with two inward projections 20 the lower edges 21 of which slant, as shown. The yoke is provided with recesses having cam surfaces 22 coacting wi h the cam surfaces 21 of the projections.

When the parts are in normal position the cam surfaces 21 and'22 engage as shown in Fig. 3 holding the pad-carrier up and the pad 14 in. close engagement with the type surfaces of the printing member. When the plunger 4 is depressed the two cam surfaces 21 and 22 at first separate allowing the padcarrier 17 to fall so as to withdraw the pad 14 from the type surfaces by a downward movement in a substantially"vertical direction, The wings 13 are then thrown out carrying the pad-carrier 17 an'dpad 14 to one side, to the position shown in Fig. 2. During a portion of the latter movement the pad or pad-carrier 17 contacts with the paper so as to lift its wing, as shown in Fig. 2. On the return movement the pad first swings toward the type faces through an arc until the surface 21 engages the sur face 22, whereupon a cam action takes place drawing the pad 1e upwardly into engage ment with the printing faces in the position shown in Fig. 3. These means permit the pad to pass the flat printing plate 12.

In order to guide the printing members I provide the frames with slots 23 affording guide surfaces, and secure to the upper part of the yoke a guide 24 coacting therewith. This keeps the type in proper alinement with the side frames.

In order to secure the pad to the pad-carrier 14 I provide at the bottom of the carrier 17 a laterally projecting shelf 25 on which the pad holder 26 rests. This shelf is provided with a tooth 27. The pad holder 17 has a hook 28 whose nose can be swung behind said tooth 27 so as to lock the holder and its pad in place upon the carrier.

The cap portion of the frame has cam surfaces 29 and the wings have cam surfaces 30 coacting therewith, whereby when the cam surfaces 29 and 80 engage on the upward throw of the plunger the wings 13 are forced inward to the positions shown in Fig. 1 and are held in that position until the plunger is again depressed. The cam surfaces 29 and 30 insure the action of the cam surfaces 21 and 22.

In operating the stamp the plunger is depressed by pressure on its handle, the cam surfaces coacting first with the lugs and then with the paper thrust the wings out-- ward, the pad carrier being permitted to move downward and then in the arc of a circle by reason of the cam surfaces 21, 22, and the printing members being guided by the guide coacting with guiding surfaces on the frame. On the return to normal the reverse action takes place.

As will be evident my invention permits of modifications of the embodiment above described Without departing from the spirit thereof or the scope of the appended claims.

W hat I claim is:

1. In a hand stamp the combination of a printing member, a wing pivoted thereto, a frame in which said member moves, said frame having an inwardly projecting lug near its base and said wing having a cam surface coacting therewith to throw said wing outwardly. v

2. In a hand stamp the combination of a printing member, a wing pivoted thereto, a frame in which said member moves, said frame having two inwardly projecting lugs near its base, and said wing having two cam surfaces coacting therewith to throw said wing outwardly.

3. A printing member having a laterally extending type surface, an oscillating wing pivoted thereto, a pad carrier movable longitudinally relatively to said wing and carried thereby, a pad on said carrier, means for moving said pad carrier longitudinally upward relatively to said wing as said wing swings inward.

4:. In a stamp, the combination of a frame, a printing member reciprocating within the same, a wing pivoted to said printing member, an ink pad carrier, supported by said wing and longitudinally movable thereon, said carrier and said printing member having coacting cam surfaces holding said pad carrier in proximity to the printing faces of said printing member when the printing member is retracted.

5. In a stamp, the combination of a frame, a printing member reciprocating within the same, a wing pivoted to said printing member, an ink pad carrier, supported by said wing and longitudinally movable thereon, said carrier and said printing member having coacting cam surfaces holding said pad carrier in proximity to theprinting faces of said printing member when the printing member is retracted, and cam surfaces on said frame and wing holding said wing in closed position when said printing member is retracted.

6. In a hand stamp, the combination of a frame having vertical slots, a printing member reciprocating in said frame, and laterally projecting guides carried by said printing member and extending into said slots and through the side members of said frame for keeping said printing member in fixed alinement with said frame, said guides being located at the top of said printing member.

7. In a stamp, a pad carrier having a laterally extending portion, a pad holder, resting on said portion, a stud projecting downward from said portion and a hook on said pad holder engaging said stud, said hook being pivoted on said holder so as to swing parallel to the plane of the bottom thereof and the plane of said extending portion.
