Specification of Letters Patent.
Patented Dec. 29, 1914.
Original application filed January 3, 1910, Serial No. 535,962. Divided and this application filed April 20,
` 1914. Serial No. 833,051.
To ZZ lello/i1 it may concern.'
Be it known that I, HARRY C. GAMMETER, a citizen of the United States, residlng at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Removable Form-I-Iolders for Printing-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.
My Patent No. 1,094,065 shows, describes and claims a rotary printing machine having a removable segment provided with rails plication is a division.
The present invention is hereinafter more fully explained and its essential characteristics are. set out in the claims.
In the drawings, Figure '1 is a front elevation of a rotary printing machine equipped with my removable segment and improved holding means; Fig. 2 is a vertical transverse section of the same.
Referring to the drawings, the frame of my machine consists of a base 10 and vertical end plates 11 and 12. Mounted in these end plates is a rotary shaft 13 provided with suitable means for rotating it, as, for eX- ample, the crank 14. Rigid on this shaft are a pair of end members 15 and 16, which are in the form of wheels, rings or spiders. Rigid with the wheel 16 is a gear 17 which meshes with a'gear 19, connected with the platen 18.
Resting on rotary supports or wheels 15 and 16 is the segment 20 provided with longitudinal rails 21, some of which are omitted in Fig. 2 for clearness of illustra-tion. Each rail has an ovcrhangmg edgeso that 1t 1s adapted to cooperate with its neighbor to.
In installing my segment, it is only necessary to place it on the end members 15 and 16, and, with a suitable pressure of the operators hand, spring the hooks 32 about the shaft. The bent portion of the lspring 30, as shown most clearly in Fig. 2,enables these springs to have their ends pass about the shaft, and, at the same time, provide suitable tension, when the segment is in place, to hold it properly on its seat. To unlock the segment it is only necessary to lapply nger pressure on the curled end of the hooks 32, which frees them from the shaft, and the segment may then be lifted ofl". The end members 15 and 16 are preferably braced by tie rods 29 and the transverse webs 22 may be formed to substantially abut the tie rod, though the segments actually seat on the end members 15 and 16.
,The printing drum, when the segment is in place, it will be seen, is open for substantially half of the circumference. In this half are mounted the two ribbon spools 40 and 41, which are suitably journaled in the end members 15 and 16.l These spools carry an inking ribbon 42, which extends across guide rods or rollers 43 and about the segment and supply the ink for the impression.
Havingthus described my invention, what I claim is:
1. The combination of a rotary member comprisingr a shaft and a pair of end rings. a removable tvpeholding segment adapted to seat onsuch rings, and a spring mctal hook carried by the segment and adapted to engage the shaft.
2.' The combination of a rotary member comprising a shaft and a pair of end rings.
a removable segment adapted to' seat enf such rings, said segment having a plurality" 3. The combination of a shaft, a pair of i supports carried thereby, a remova'ble typeholding segment seating on such support and having an internal web extendmgv beried by said web, and a spring hook mounted on said rod and adapted to engage said shaft between said supports.
5 4. The combination of a' shaft, a pair of ring-like members carried thereby, a segment adapted to seat on such ring-like mem bers, typeholding means carriedl by said segment, said segment having a plurality of 10 transverse internal webs extending between the ring-like members,
a rod carried by said webs, .and -at one end around said rod and formed at a sheet metal spring hook .curled the other end with a hook portion adapted to spring over said shaft.
In testimony whereof, I hereunto affix my signature in the presence of two witnesses.
E. Komme,V ALBERT I-I. BATES.
