SELF-IN KIN G HAND-STAMP.

Specification of Letters Patent.

Application filed. February 10, 1915. Serial No. 7,224.

To all whom it may concern .1

Be it known that we, HARRY S. FoncER and TOREY Ross, citizens of the United States of America, and residents of Chicago,

county of Cook, and State of Illinois, have invented certain new and useful Improvements .in Self-Inking Hand- Stamps, of which the following is a specification.

Our invention relates-to self inking hand stamps, and has for its object improvements in such stamps.

In the accompanying drawings Figure 1 is a side elevation;

Fig. 2 is a rear elevation;

Fig. 3 is a section on line 33 of Fig. 2;

Fig. 41- is a similar section on line 4-4 of Fig. 2 but with the stamp moved down to its printing position;

Fig. 5 is a section on line 55 of Flg. 2;

Fig. 6 is a partial section on line 6-6 of Fig. 1; and

Fig. 7 is a sectional detail.

There is an outer frame composed of side plates 10 and 11 which are connected together by tie bolts 12 held in place by screws 13. The plates 10.and 11 are similar stampings from sheet metal but are formed into right and left by reason of guide channels 1& being formed in their inner faces by bending the plates.

Operating in the guides 14 are two up right slides or standards 15 connected together by a bridge 16 to which is secured the handle 17. The slides 15 and bridge 16 are separate pieces connected together by rivets, the heads of which are shown in Figs. 3 and 4. The slides 15 have their edges 18 bent to form exterior beads and inwardly projecting edges as best shown in section in Fig. 5. The actual bearing is at the points of contact between the beads 18 and the inner corners of the guide channels 14:. As thus constructed, these beads leave an open channel 19 between the guides 14 and slides 15.

The lower ends of the slides 15 are bent inward and then upward to form lips 20, and between these lips is secured the bridge 21 by means of the screws22. The operating parts to be hereinafter described are located between the lips 20 and the slides 15 of which they are extensions, and are the same for stamps of all widths bet- ween plates 10 and 11.

Supported in the plates 10 and 11 is a shaft 23 on which are pivoted arms 24 connected together by abridge 25, and supported in the slides 15 is a shaft or rod 26 on which are pivoted links 27 which extend downward and connect to arms 24. Springs 28 on shaft 23 act to'elevate shaft 26 and parts attached thereto.

The stamp 29 is secured in a box 30, and to the rear edge of the box 30 is secured a spring 31 having the shape shown in Figs. 3, 41 and 5. The box 30 has its back against the lower face of the bridge 21, while the free end of the spring 31 engages a small groove '32 in the upper face of the bridge 21 and acts to clamp the box to the bridge. The spring is in the form of a handle which makes it convenient to withdraw the stamp box from the bridge and to return it to place.

The stamp pad 33 is held in a similar box 34:, which box is provided with a similar spring 35 adapted to clamp the pad box to the bridge 25. The pad box 36L may be withdrawn and replaced in the same way as set forth for stamp box 30.

When the stamp is depressed by placing the hand upon handle 17 the slides and their connecting parts are moved downward in the guides. The downward movement of the shaft 26 causes the links 27 to push upon the arms 2st so as to turn them on their pivoting shaft 23 and swing the pad 33 out of the path of the stamp 29. When the handle is released the spring 28 returns the stamp to its elevated position, drawing the pad against the bottom face of the stamp.

One end of the shaft 26 projects beyond the face of the slide 15 into the space 19 between the beads 18, and in the plate 10 directly below this projecting end is a hole 36. Pivoted to the plate 10, and in the space 19 below the hole 36, is a catch 37, shown in dotted lines in Fig. 1, and the free end of this catch is bent to project out through the hole 36 as shown at 38. .When the stamp is depressed so that the projectingend of the shaft 26 is opposite the lower portion of the hole 36, the catch 3738 may be moved over the end of the shaft and catch it and hold the stamp in a depressed position near the lOWer extremity of its movement. When held in this position the pad and stamp 29 are in a position. to be conveniently withdrawn as before described. The face of the catch 37 below the projection 38 is in the form of a cam adapted to be engaged by the end of the shaft 26 when the stamp is moved from its held position to its printing position. In such a movement, the engagement of the shaft 26 with the cam surface moves the catch back into the position shown in Fig. 1 so that it will be free from the shaft 26 and permit the stamp to rise to its full extent.

I It will be observed from the foregoing description that the construction of the side plates 10 and 11 is independent of the length of the tie bolts. In other words, they may be connected together by tie bolts of any length. Also, that the construction and operation of the slides 15 are independent of the length of the bridges 16 and 21 which connect their upper and lower ends and support the handle and the stamp box. Also, that the construction and operation of the arms 9A, and of the links 27 which operate these arms, are independent of the length of the bridge'2'5 which connects these arms and su, ports the pad box. Also, that the manner of oldi-ng the removable stamp and the removable pad by means of central clamping springs makes the holding means independent of the length of the stamp and pad. lhe

length of these connecting devices (tie bolts .and bridges is determined the desired length of the stamp '29 and pad '33, and they in turn -determine the width of the self inking device as a whole. It will be seen from .these facts that the main parts of the apparatus have been devised so that they are standard for any width of self inker and that these main parts are connected together by simple and inexpensive pieces which are made in lengths suitable for the desired width of stamp.

On each side plate at the lower central portion of the guides is an inwardly pro- ;j-ecting lip 39 which serves the double purpose of a guide for the printing and a stop for the downward movement of the stamp whenthis downward movement is made in handling the stamp at other times than when it is printing. They become a guide by reason of being placed opposite the middle points of the ends of the stamp 29 when in printing-position. They become a stop for the stamp by reason of the lower parts of the .slides 15, which are bent to form the lips 20, being carried downward, as shown at 40 in Fig. 6, far enough to engage the lips 39 immediately after the face of the stamp :29 has passed below the plane upon which the side plates rest when the self inker is used for printing. It will thus be seen that the extensions to slides 15 are so connected that they form lips 20 for securing the bridge 21, that when bent to form these lips 20 they provide spaces or pockets 41 within which the links 27 may operate stamp, said connections consisting of bridges connecting the slides, ,a bridge connecting the outer ends of the arms, and ties between the side plates.

In a self inking hand stamp, a frame providing guides, slides operating in said guides, said slides having their lower ends bent inward and upward to form lips, a bridge connecting the lips of opposite slides, a second bridge connecting the upper ends of said slides, .a stamp mounted upon the first bridge, a handle mounted upon the second bridge, and a spring supporting said slides in said frame. 7
