1 235 53, specific ion of Letters Fateinted Nov. 19, rare.
original application filed April 21, 1917, Serial No. 133,579. Divided and this application filed July 1917. fierial No. 1%,419.
T 0 all whom it may concern;
Be it known that l, FRANKLIN Nonnvan, a. citizen or" the United States, and a resident of Chicago, in the county of Cool; and State of Illinois, have invented certain new and useful Improvements in Printers Rollers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accorn-' panying drawings, and to the characters oi reference marked thereon, which "form a part of this specification.
This invention relates to improvements in composition rollers of the general type shoivn in my prior U. S. Letters Patent No. 1161756 and adapted for use as an inking roller for printing presses.
The object of the present invention is to I nent'thickness of the core and a predetermined pour to produce the core of said roller.
lln accordance with my invention the core is formed on an adapter tube which is made of somewhat greater length than the body of the core and of a diameter somewhat reater than that of the roller stock. The
core is formed on this adapter tube, preferablv in the machine illustrated in my pending application for U. S. Letters Patent, Serial No. 163579, of which this application is a division. After being formed on the adapter tube the roller is shipped to the place of use and the stock is inserted through the adapter tube and is equipped with suitable supporting and centering means whereby the roller may be centered on the stock and rigidly attached thereto.
The invention consists in the combina tion and arrangement of the parts shown'in the drawings and described in the specification and is pointed out in the appended claims.
In said drawings:
Figure 1 is an axial section oi the roller and adapter tube as completed at the fad tory.
Fig. 2 'is a similar section showing the Fig. 3 is an enlarged side elevation of a portion of one end of the finished roller,
without the adapter tube.
As shown in the drawings, 10 designates the core of the roller and 11 the outer shell or face layer thereof.
l2 designates the adapter tube, which oomprises a section of pipe or tube of proper gage to properly support the core at the innor side thereof. Said tube extends at its ends a distance beyond the ends of the core and shell.
13 designates the roller stock which is made of a length to extend at both ends some distance beyond the tube. Said stock is located centrally in the adapter tube and is supported in and centered with respect to the axis of said tube by means of conical collars 14, 14 that are slipped over the ends of the stock and may be attached thereto in any suitable manner, as by means of the set screws 15.
The core and shell may be formed about said adapter tube, preferably by the particular method described in the aforesaid application. So far as the present invention is concerned, however, the roller may be otherwise fabricated. After the roller is formed the ends of the core are ground oii to produce the tapered portions 16, shown in Fig. 8, and the distance between the bases of said tapered portions constitutes the active length of the roller. Said ends of the core are tapered or cut away so as to avoid pressure of the roller acting against the sharp annular edges at the ends of a transversely cut core.
An advantage of the construction described, in addition to the fact that it avoids the necessity of shipping the stock to the roller factory and reshipping it with the roller, is that a smaller quantity of the core material is used than in constructions where the core is formed directly on the stock, the material being only that required to fill the annular space between the adapter tube and the shell of the roller.
Another advantage of the construction is that, for a given diameter and length of roller, and with the adapter tube made of uniform diameter, the amount of core material to be poured may be definitely predetermined so that an accurate quantity of the material is poured to produce the core. Where the core is formed directly on the stock, it has been found that the stocks from different printing shops vary so substantially in diameter that the person supervising the pouring of the core material can never accurately know just the amount of material to pour to produce a perfect core.
Another advantage of the construction is that the roller and adapter tube, minus the stock, is considerably lighter than a roller having its stock embedded therein so that the cost of shipping is materially reduced.
I claim as my invention 1. A resilient hollowroller, an adapter tube therein and bonded thereto and a stock extending through said tube, with means on the stock to engage the ends of the tube to center the stock therein.
2. A resilient hollow roller, an adapter tube therein and bonded thereto and extending at its ends beyond the roller, a stock extending through and beyond the tube, and removable centering means on the stock to engage and center the tube on said stock.
3. A resilient hollow roller, an adapter tube therein and bonded thereto, a stock ex within and extending at its ends beyond the core.
5. A roller comprising an outer shell layer, an inner core, an adapter tube within the core, and a stock smaller than and extending through said adapter tube, With means to center and fix the stock in said tube.
6. A roller comprising an outer shell layer, an inner resilient core, an adapter tube within the core, a stock smaller than and extending through said adapter tube, and centering means on said stock to engage the ends of said tube.
In witness that I claim the foregoing as my invention, I hereunto append my signature in the presence of two Witnesses at Chicago, Illinois, this 7th day of June, 1917.
FRANKLIN H. WOLEVER.
