Description
H. SMALLMAN TURNING ROLL FOR DATING STAMPS March 1, 1932.
Filed Aug. 22, 1929 Patented Mar. 1, 1932 stares PATENT @FECE IHARRY SIVIALLIVIAN, OF PHILADELPHIA, PENNSYLVANIA, ASSINOR TO HILL-INDE- EENDENT MFG. 00., OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENN- SYLVANIA TURNING-ROLL FOB DATING-STAMPS Application filed August 22, 1929. Serial No. 387,668.
ing and numbering stamps to turn the bands upon which they rotate, in order that the the invention may be applied is designated which contain the printing characters. It is extremely nnportant 1n the use and operation of these stamps that the band carrylng portions of the roll be concentric with the pin band will be under uniform tension and may be freely movable by 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 posit-ions it may not engage the bands with sufiicient force to cause them to move. These conditions cause undue wear and deterioration of the band and render it dificult to change the printing portion of the band by the manipulation of the flange of the roll.
Heretotore these rolls have been of two kinds, one made from a solid bar of metal in the manufacture of which a large amount of metal was wasted, which rendered the rolls very expensive to make. The other kind consisted of a plurality of parts made of metal, wood, fibre, cork, or metal strips fastened together in various ways.
The object of this invention is to improve upon these rolls, and particularly in the way in which they are made and the manner of attaching the flange to a metallic hub, so as to form a rigid connection therebetween, and in such a construction the roll has all of the advantages of the one made from the solid bar of metal, but is considerably less expensive.
In the accompanying drawings:
Fig. 1 is a perspective view of a conventional form of dater-stamp to which the in vention may be applied;
Fig. 2 is a detached perspectlve view of one of the rolls;
Fig. 3 is a sectional view therethrough;
Fig. l is a disassembled perspective view of the parts of the roll; and
Fig. 5 is a transverse sectional view.
The dating or numbering stamp to which generally by the numeral 1 and since this may be of a form and construction well known in the art, it need. not be described in detail. However, these stamps are provided with bands 2 containing the printing char acters, and which are adapted to be turned in order to bring the various characters successively into the right position for printing.
v To accomplish this, turning-rolls are used which are journalled on a pin or shaft 3 extending transversely across the stamp 1, as shown in Fig. 1.
The printing-rolls should be of a construction to hold the bands under uniform tension in order that the bands may be turned whenever the rolls are turned. These turningro-lls are-preferably constructed of a hub 4, which may be of any suitable width and diameter according to the diflerent sizes of bands with which it is to be used. The eX- ternal surface of this hub is roughened to provide a good gripping contact with the band, and one end 5 is machined to a smaller diameter than the main body portion of the hub, and has slots 6 formed in this reduced end 5 as shown in Figs. st and 5. A flange 7 is adapted to be secured to the hub 4, which flange has its periphery serrated or knurled, and the center is cut or blanked out as at 8 to fit over the reduced end 5 of the hub. Lugs or tangs 9 are formed in the cut-out portion 8 to fit in the slots 6 in the reduced end 5 of the hub, in order to hold the parts together securely. After the flange 7 has been fitted over tie reduced end 5, this end may be slightly turned over to hold the flange in place, or the parts may be riveted or otherwise securedtogether as found desirable.
By making the rolls in this way, they have all the advantages of the rolls made from the solid bar of metal, at considerably less eX- pense. The parts are securely fastened together, and are so constructed as to apply uniform tension to the bands to move these whenever the flanges are turned.
I claim:
1. A turning-roll for a stamp comprising a hub having a slot cut therein, a flange fitted over a portion of the hub, and having a radially extending lug thereon extending into the slot for holding the parts together.
2. A turning-roll for a dating or printing stamp comprising a metallic hub having a reduced end, said reduced end having a slot formed therein, and a flange iitted over said reduced end and having a radially extending lug thereon extending into the slot to hold the parts securely together.
3. A turning-roll for a dating or printing stamp comprising a metallic hub having a re duced end, said reduced end having opposed radial slots formed in the face thereof and a flange fitted over the reduced end of the hub and having radially extending lugs formed thereon and extending into the slots for rigidly and securely holding the parts together.
4. In a dating-stamp, the combination with a band for printing characters and a journalpin, of a turning-roll for said band comprising a hub having a roughened external surface and journaled on said pin, said hub having a reduced end formed with opposed radial slots cut in the face thereof, and a flange having a central opening fitted over the reduced end of the hub and having opposed radially extending lugs extending into the slots for securely and ri idly holding the flange and hub together.
5. A turning roll for a dating or printing stamp comprising a hub having a radially extending groove in the face thereof, and a flange fitted over the end of said hub and having a lug arranged approximately in the plane of the flange and disposed in the groove to prevent relative turning between the hub and flange.
6. A turning roll for a dating or printing stamp comprising a hub having a radially arranged groove in the face thereof, and a flange fitted over the end of the hub and having a radially arranged lug arranged in the plane of the flange throughout its length and disposed within the groove to securely fasten the hub and flange against relative turning.
7. A turning roll for a. printing stamp comprising a hub having an approximately radially extending groove in a face thereof, and a single turning flange for the roll and applied to one end only thereof, said flange being fitted over the end of the hub and having a lug arranged approximately in the plane of the flange and disposed in the groove to prevent relative turning between the hub and flange.
8. A turning roll for a printing stamp of the character described comprising a hub having a reduced end and provided with an approximately radially extending groove in the face of said reduced end, and a single turning flange for the roll and applied to one end only thereof, said flange being fitted over the reduced end of the hub, and having a lug arranged approximately in the plane of the flange and extending into the groove to prevent relative turning between the hub and flange.
9. A turning roll for a printing stamp of the character described, comprising a hub having a roughened external surface to prevent slipping of a printing-band thereon, said hub having a single reduced end provided with a radially extending groove in the face thereof, and a single turning flange for the roll and applied to one end only thereof, said flange being fitted over the reduced end of the hub and having one or more lugs arranged approximately in the plane of the flange and disposed in the groove to prevent relative turning between the hub and flange.
10. A turning roll for a. printing stamp of the character described, comprising ahub having a radially extending groove in a face thereof, and a single turning flange for the roll and applied to one end only thereof, said flange being fitted over the end of the hub, and having one or more lugs arranged approximately in the plane of the flange and disposed in the groove to prevent relative turning between the hub and flange, said lug 0r lugs extending partway only across the end of the hub and terminating substantially short of the central axis thereof. 7
