TURNING ROLL FR DATING STAMPS Filed Aug. 22, 1929 JAM 7/ Patented Mar. 1, 1932 UNITED STATES PATENT OFFICE HARRY SMALLIVIAN, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO HILL-INDIE PENDENT MFG. 00., OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENN- SYLVANIA.

TURNING-ROLL FOR DATING-STAMPS Application filed August 22, 1929. Serial No. 387,669.

This invention relates to an improvement in turning-rolls for dating-stamps.

These turning-rolls are designed for use in dating or numbering-stamps to turn the bands which carry the printing characters. It is extremely important in the use and operation of these stamps that the band carrying portions of the rolls be concentric with the pin upon which they rotate, in order that the band will be under uniform tension and may be freely movable by the rotation of the roll.

When the roll is eccentric in certain positions, it will unduly stretch the band and put it under excessive tension, while in other positions it may not engage the band with sufficient force to cause it to move. These conditions cause undue wear and deterioration of the band and render it difficult to change the printing portion of the band by the manipulation of the turning-roll.

Heretofore these rolls have been of two kinds principally, one made from a solid bar of metal out out to form the roll, and due to the large amount of metal wasted this form is very expensive to make. The other kind comprises a plurality of parts made of metal, wood, fibre, cork or metal strips fastened together in various ways.

The object of the present invention is to improve the manner of attaching the flange to the hub of the turning roll so that both of these may be constructed of metal and yet may be so securely fastened together as to have all the advantages of the roll made from the solid bar of metal, but at considerable less expense.

In the accompanying drawings:

Fig. 1 is a perspective view showing a conventional form of dating or printing-stamp;

Fig. 2 is a detached perspective view of one of the turning-rolls;

Fig. 3 is a sectional view therethro-ugh;

; and

Fig. 4 is a disassembled perspective view of the parts of the roll.

The dating or printing-stamp shown in Fig. 1 is of a conventional form, and is designated generally by the numeral 1. This stamp has the usual bands 2 which carry the printing characters, and are adapted to be moved successively for bringing different portions of these hands into position for printing. For this purpose the turning-rolls are utilized which are journaled on the pin 3 extending across the stamp 1.

The turning-roll embodying this invention comprises a hub '4 which may be of any suitable width and diameter according to the different sizes of the bands which may be used thereon. The external surface of the hub is roughened to provide a good gripping contact with the band 2,and one end 5 is machined to a smaller external size or diameter as shown in Figs. 2 and 4. The opposite sides of this reduced end 5 are flattened as at 6. A turning flange 7 has its periphery serrated or knurled and its center is cut or blanked out as at 8 to fit the reduced end 5 of the hub and the sides 6 of this reduced end to form a firm contact or bearing between the hub and the flange. The two parts may be fastened together by slightly upsetting the reduced end 5 or by riveting or other suitable means.

By making the turning rolls in this way, they have all of the advantages of rolls made from the solid bar of metal, but at a considerable less expense. The rolls are entirely metallic and the flange is securely fastened to the hub, so that there is uniform contact and pressure applied to the bands at all times which keep these in their proper shape.

I claim:

1. A turning-roll of the character described comprising a hub having a reduced end with an irregular portion transverse thereto and a flange fitted over said reduced end and secured thereto.

. 2. A turning-roll for a printing or datingstamp comprising a hub having a reduced end provided with flattened sides and a flange fitted over said reduced end and having an opening therein corresponding thereto and securely fastened in place.

3. A turning-roll for a printing or datingstamp comprising a metallic hub having a roughened external surface and having an end machined to a reduced diameter, the sides of said reduced end being flattened, and a flange having a central opening therein, corhub and protruding from an end of the hub,

responding to the shape and approximately and a single turning flange for the hub and equal in size to the reduced end of the hub fitted over the rib and secured to the hub.

and fitted thereover for securely fastening the flange in place on the hub.

4:. In a printing or dating-stamp, the combination with a band designed to carry printing characters and a pin extending across the stamp, of a turning-roll journaled on said pin for causing a turning movement of the band, said turning-roll comprising a metallic hub having a roughened external surface for engaging the band and having one end reduced in diameter, the sides of said end being flattened or of irregular shape, and a flange having an opening therein corresponding in size and shape to the reduced end of the hub and fitted thereover to be securely fastened to the hub.

5. A turning roll for a printing or dating stamp comprising a hub, ribs arranged at an angle to the axis of the hub and protruding from anend thereof, and a turning flange having an opening therein corresponding in size and shape to the ribs and fitted thereon for securing said flange to the hub.

6. A turning roll for a printing or dating stamp comprising a hub, ribs arranged in alignment with each other on opposite sides of the axis of the hub and approximately at right angles to said axis, said ribs protruding from the end face of the hub, and having approximately straight side edges, and a turning flange fitted over the ribs and having an opening therein corresponding in size and shape With the ribs for fixing the flange and hub together and against relative turning movement.

7. A turning roll for a printing-stamp of the character described comprising a hubhaving a radially arranged rib at an end thereof, and a turning flange fitted over the rib and secured tothe hub.

8. A. turning roll for a printing-stamp of the character described comprising a hub having a radially-arranged rib at an end thereof and provided With approximately straight opposite sides, and a turning flange having an opening therein corresponding in size and shape to the rib and-fitted thereon for securing said flange to the hub.

9. A turning roll for a. printing stamp of the character described comprising a hub having one or more radially arranged ribs protruding from an end thereof and extending at right-angles to the axis of the hub, said ribs terminating substantially Within the periphery of the hub, and having approximately straight opposite sides, and a turning flange fitted over the ribs and secured to the rib arranged at an angle to the axis of the In testimony whereof I afiix my signature.
