Application filed August 29, 1910. Serial No. 579,558.

T 0 all whom it may concern:

Be it lmown that we, HARRY S. FoLGnR and ASA M. COMSTOCK, citizens of the United States of America, and residents of Chicago, county of Cook, and State of Illinois, and Muskegon, county of Muskegon, and State of Michigan, respectively, have invented certain new and useful Improvements in Band Dating Attachments for Self-Inking Hand-Stamps, of which the following is a specification.

Our invention relates to band dating attachments for self-inking hand stamps and has for its object improvements in such attachments and the makings of such attachments as independent articles which may be readily connected to and removed from the hand stamp.

In the accompanying drawings Figure 1 is an elevation of a hand stamp in its ordinary prlnting position showing the attachments connected to the stamp; Fig. 2 is a sectional elevation corresponding to Fig. 1; Fig. 3 is a plan of the attachment portion, the other parts being in section on line 33 of Fig. 1; Fig. 4 is-a section on line 44 of Fig. 1; Fig. 5 is an enlarged end elevation of the band supporting devices; and Fig. 6 is a still more enlarged perspective view of the spring used to maintain tension on the bands.

The hand stamp herein illustrated is one in which the printing characters engage an inking pad above and are reversed in the act of using the stamp. The particular mechanism by which this reversing is done is immaterial and the one partially illustrated is well known in the art. 1

The frame 10 is supported in a bail 11, on the upper hand of which is the handle 12. Running through the bail 11, frame 10 and the reversing cam 13, are screws 14 by which the die-plate 15 is pivoted. The inner ends of the screws 14 are held in brackets 16 which are fastened to the back end of the die-plate 15. This die plate has an opening through the central portion and on the lower part of the die plate is secured the die 17 which constitutes the ordinary stamp. This die also has a central opening. The attachment is secured to the back face of the die plate by means of studs 18 riveted into die plate 15. The frame 19 of the at tachment has feet 20 through two or more of which are holes adapted to fit over the studs 18. Nuts 21 secure the attachment in position. The location of this attachment is such that the bands carried thereby project through the openings in the die plate and the die.

The frame 19 is U-shaped and each leg of this U-shaped piece is pressed outward into a semi-cylindrical form for the purpose of containing and inclosing the bodies of screws 22 and springs 23. Inside of this U-shaped frame is a band holding frame 24 which has at its upper ends projections 25 adapted to enter openings 26 in the frame 19. The object of these projections and these openings is to furnish a guide for the upper end of the band holding frame when said frame slides in the main frame 19. Running through the two upwardly projecting legs of the hand holding frame 24 is a shaft 27 upon which are mounted a series of rolls 28. The lower part of the band holding frame consists of a transverse bar 29 which preferably is integral with the sides of the hand holding frame 24. Mounted upon the rolls 28 and the bar 29 are the type bands 30.

Above the bar 29 is a loose transverse bar 31 which projects beyond each of the up ward legs of the band holding frame 24. Resting on top of this transverse bar 31 is a spring 32 secured to the upper part of which are legs 33 having holes 34 through which the shaft 27 passes. The holes in the vertical legs of the band holding frame 24 are slotted as shown in Fig. 5 so as to permit the rolls with the shaft 27 to move vertically in the frame 24. The spring 32 with its legs 83 are so related to the rolls 28 and the transverse bar 29 and also to the length of the bands 30 that said spring will maintain the bands under a uniform tension. Heretofore in dating devices of this character, the bands became loose after a time and it was not easy or convenient to shift them when it was desired to shift them, and they are liable to displacement on account of their looseness. By this adjustment the bands are always given a uniform tension and as there is a friction which will prevent the bands from being readily displaced, they will be normally held in their desired position. If, for any reason, the bands should stretch so that sufficient tension should not be maintained, the spring 32 may be given additional tension so as to maintain the tension at any desired amount.

The outer ends of the transverse bar 31 enter the semi-cylindrical parts of the frame 19 and havetapped ends for engagement by the screws 22. By adjusting the said screws 22, the bar 31 may be raised and as this bar is connected through spring 32 and the legs 33 to the band holding parts, such adjustment will serve to raise the band holding frame 2 and the parts supported thereby. The springs 23 surrounding the screws 22 extend between the upper part of the cylindrical casing for the said screw and the outer ends of the 'loose part 31. The result of this spring action is to force the band holding frame 24; as far downward as the screws 22 will permit it to move while at the same time the said springs serve as a yielding backing to permit the frame 24: to slide inward in the frame 19.

It will be observed from the foregoing description that by releasing the nuts 21, the dating attachment may be readily removed and returned to position. In hand stamps as heretofore made, this has not been possible without disturbing the other parts of the apparatus, because in such previously made constructions the pivot for the die plate consisted of a bar which ran through the dating attachment. As a consequence, the dating attachment could not be removed until this pivoting bar was removed and such removal consisted in practically taking the entire hand stamp apart.

What we claim is 1. In a self-inking hand stamp, a dieplate, means by which said die-plate is reversed, a dating attachment secured directly to the back face of the die-plate, dating bands so supported in the attachment as to permit the date line of said dating bands together with the bands to yield while in the act of printing, and means for quickly and easily removing the attachment and the bands supported therein.

2. In a self-inking hand stamp, a die plate, a self-contained and unitary dating attachment consisting of a frame provided with projections by which it is fastened directly to the back face of the die-plate and by which it may be quickly attached to and removed therefrom without disturbing the other parts of the stamps, and bands yieldably anounted in said frame so as to permit the printing characters to adjust themselves to uneven printing surfaces.

3. In a self-inkinghand stamp, the combination with a-die-plate, and means by which said die plate is reversed for inking and printing, of a containing frame removably secured to the die-plate, screws by which said containing frame may be removed without disturbing the position of other parts of the stamp, a band-holding frame within the containing frame and arranged to project through an opening in the die-plate, screws extending from the exterior of the containing frame and engaging the band-holding frame for adjusting the latter with respect to the former so that type on the bandholding frame may be brought to a desired relationship to the type carried by the dieplate while such die-plate is in position to the end that the quality of the adjustment may be observed while being made, and springs for permitting the band-holding frame to yield inward from adjusted position.

41-. In a hand stamp, a containing frame, a die-plate secured thereto, a hand holding frame within the containing frame and provided with openings at its opposite sides, a loose bar extending through the openings of the band holding frame and into recesses in the containing frame, a band tension spring between the loose bar and the band holding frame, and screws extending from the exterior of the containing frame and engaging the loose bar for adjusting the position of the band holding frame with respect to the die-plate while the die plate is in position.

5. In a self-inking hand stamp, a die plate having an opening therethrough, a dating attachment consisting of a -removable frame and a self-adjusting band-holding frame secured to said die-plate, means for adjusting the band holding frame with respect to the removable frame, and means by which said attachment may be quickly removed without disturbing previous adjustments.

6. In a hand stamp, a die-plate having an opening therethrough, a frame secured to the back of the die-plate, bands and a band holder slidably mounted in said frame and arranged to project through said opening, a removable bar projecting through the holder, screws in the frame for engaging the bar to adjust the holder, and springs for permitting the holder to slide in the frame in one direction from its adjusted position.

7. In a self-inking hand stamp, a dieplate, a containing frame secured thereto, a band-holding frame within the containing frame, a loose bar extending through openings in the band-holding frame and into other openings in the containing frame, a spring between the loose bar and the bandholding frame for maintaining tension on the bands, and screws extending from the exterior of the containing frame and engaging the loose bar for adjusting the handholding frame with respect to the die-plate without removing the latter.

8. In a dater for handstamps, the combination with a frame, bands and a bandholder therein, and screws for adjusting the holder in the frame, of a loose bar extending through the holder, a spring associated with said bar for maintaining a tension on said bands, and other springs also associated with said bar for permitting said holder to slide in said frame.

9. In a self-inking hand stamp, a dieplate, a frame secured to the die-plate in such a manner that it may be easily removed therefrom, bands and a band holder yieldably mounted in said frame, a removable bar, screws in the frame for engaging the bar to adjust the holder, and springs for permitting the holder to slide in the frame.

10. In a self-inking hand stamp, a dieplate having an opening therethrough, means by which said die-plate is reversed for inking and printing, a containing frame secured to said die-plate, a band-holding frame supported in said containing frame, and springs for permitting said band-h01ding frame to move inwardly and away from said die-plate in the act of printing Signed at Chicago this-25 day of August 1910.
