IMPROVEMENT IN INKING APPARATUS.

Specification forming part .of Letters Patent No. 181,744., dated August 29, 1876; application led April 19, 1876.

To all whom it may concern:

Be it known that I, JONAS H. TITUS, of Detroit, in the county of Wayne and State of Michigan, have invented an Improvement in Inking-Rollers, of which the following is a speciiication My inventionrelates to an improvement in inking-rollers, such as are used for inking the forms on fast-running power-presses; and has for its object to render the roller` more d urable and less liable to melt, by making it hollow, so as to allow a current of air to be passed through it to keep it cool; and, further, to lessen the cost of the roller by making the periphery of the roller-stock of an elastic Inaterial, so as to require a less thickness of roller composition to be cast on, which elastic periphery is stretched over hoops secured to two heads, which are screwed onto a metal shaft.

Figure 1 is a perspective view of the naked roller-stock. Fig. 2 is a longitudinal section of the same.

In the drawing, A represents the shaft of the roller, having a right screw-thread cut on it near one end, and a left-hand thread, a',

near the other end, on which threads are screwed two flanged heads, B, each fitted with a metal hoop, b, over which is turned one end of a tube, O, of canvas or other fabric or pliable material, which may'be stretched and put under the required tension by screwing the heads B apart. Four keyways are cut through each screw-thread t or a', and one through the eye of the head, which is secured by a key, c, after adjustment.

The roller-stock so constructed is placed in a roller-mold, and the roller-composition is caston it in the usual manner, but of a much less than ordinary thickness, as the yielding surface of the roller-stock wil'l give the roller the required elasticity.

Slots or openings d are made in each head to allow a current of air to pass through, in order to keep the roller cool, or comparatively cool, and thus obviatev the tendency 'of the roller to mel-t under the heat generated from the friction in a fast-running press.

To force the circulation of air through the roller, the openings in one head are each included in a radial cup, e, whose mouth is open to or faces the direction in which the roller rotates, as shown in Fig. l.

What I claim as my invention is l. In an inking-roller, the combination of a hollow body formed of a fabric orV yielding material under tension between heads on the roller-shaft and openings in the said heads, to allow the passage of air through the said roller, substantially as and for the purposes set forth. V

2. The combination of the heads B, hoops b, and a pliable or yielding tube, C, with the shaft A, substantially as and for the purpose set forth.

3. 'lhe cups e, in combination with the openings d in the head B, as and for the purpose set forth.
