STEPHEN. D, TUCKER, or NEW YORK, N.
Letters Patent No. 90,702, dated June 1869.
IIVIPRQVEMENT IN LITHOGRAPHIC INKIN-GROLLERS..
.The Schedule referred to in these Letters Patent and making part of the same.
To all l:pho/ml it may concern .Be Kit known that I, STEPEEN D. TUCKER, of the city, county, and Stateof New York, have invented a new and improved Inking-Roller; and I do hereby declare the following to be a full, clear, and exact description of the construction and operation ofthe same, reference being had to the accompanying drawings, in which- Figure 1 is a view of a part of;a`rol1er;
Figure 2, a longitudinal section; and
Figure 3 a transverse section.
Similar yletters of reference indicate like parts inl all the drawings.
Heretofore, in lithographie printing, the stones have generally been inked by a roller made up of a heavy meta-l core, coveredwith a layer or two of cloth, or some similar material, and over this -a coven'ng of leather. 'I hese rollers are never truly cylindrical, and but slightly elastic, andas the stones have a dat and level surface,`the rollers require to be very heavy, or pressed down by weights or springs, in order to make every part of their uneven, and but slightlyelast-ie surface, touch the stone.
My invention consists in surrounding a metal core with a coating of rubber, oi' such thickness, and vvulcanized to such a degree, as to have the proper elasticity.
This rubber coating may be a tube, drawn over the y metal core, but I prefer it should be cast on in a mould, so as to secure a perfectly cylindrical surface.
. Over this is drawn a leathern covering, previously shaved to an even thickness, and sewed in form of a tube, having the seam on the inner side, and this-seam Vlies in a groove, cut or cast in the surface ofthe rubber to receive it. Y i
'In this manner, a roller is made with a leathern surface, perfectly cylindrical, and elastic to any degree required, so that, in rolling over the stone, the two surfaces will come perfectly in contact, even if the surface of the stone should be somewhat uneven, as is sometimes the case.
Buckskin, or any 'similar material, may be used as an outside covering, and it may be sewn together over the rubber, and not require the groove for the seam, but I prefer leather put on in the manner de- .Seribed above.
combined with an outer coveringof leather, O, or its y equivalent, substantially as described and specified. Witnesses: SPEPHEN D. TUCKER.
