FEED-ROLLER FOR PLNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 280,720, dated July e, 1883. Application led March 16,1883. (No model.)

To all whom it may concern,.-

Be it known that I, ABRAHAM V. CRoss, of Williamsport, in the county of Lycoming and State of Pennsylvania, have invented certain new and'useful Improvements in Feed-Rollers for Planing-Machines; and l do hereby declare that the following is a full, clear, and exact description thereof, .which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a perspective view of my'improved presser and feed-roller. Fig. 2 is a vertical cross-section of the same. Figs. 3 and 4 are detail views; and Figs. 5 and 6 are crosssections of slight modifications of the roller.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to feed-rollers for planing-machines; and it has for its object to provide a feed-roller which will yield to any unevenness in the lumber to be planed, and at the same time will be strong and durable, thus obviating an objection raised against rubberfaced feed-rollers; and it consists to that effect of the improved construction and combination of parts of a feed roller having springcushioned projections or lugs sunk into its face, which will yield to any Vunevenness upon the face of the lumber, and at the same time retain a firm hold or bearing upon the same, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the roller, which is preferably made of solid metal, and having journals B at its ends, upon which it turns. A series of radiating cylindrical bores or recesses, C, preferably arranged in rows parallel to the aXis of the roller, extend from the outer surface of' the same toward the axis, and cylindrical plugs or buffers D, having an annular flange, E, at their lower ends, are'inserted in the recesses, resting upon spiral springs F, bearing against the bottom o f the recesses. Tubular sleeves Gare inserted into the recesses, preventing the spiral springs fromforcing the plugs out of the same, the sleeves fitting loosely around the plugs, and the flanges bearing by the tension of the spiral springs against the lower edges of the sleeves. The sleeves are held in place by means of screws H, fitting into screwthreaded holes formed by corresponding longitudinal grooves, I, in the sides of the recesses and in the sides of the sleeves, ca ch groove having one-half of the thread. It will be seen that by having these spring-cushioned plugs projecting from the surface of the roller they will bear upon the surface of the piece of lumber fed into the machine, yielding to all uneven or rough points upon the same.

In Fig. 5 the insides of the recesses and outer surfaces of the sleeves are shown screwthreaded, thus obviating the necessity of using the fastening-screws.

Fig. 6 shows a roller which consists of an outer casing, J, having apertures K, arranged similarly to the recesses C, and the plugs, the lower ends of which bear against springs, slide upon rods L, inserted from the end of the roller, and passing through longitudinal slots M in the lower ends of the plugs.

I am aware that feed-rollers having yielding faces have been constructed, and also stationary spring-cushioned presser-feet, of which a number are raised according to the width of the plank inserted, and l do not wish to claim such construction; but

What l claim, and desire to secure by Letters Patent of( the United States, is-

l. The combination of the roller having radiating recesses extending from the surface, with the spring cushioned plugs projecting through the surface of the roller and secured in the said recesses, substantially as and for the purpose shown and set forth.

2. The combination of the roller having radiating cylindrical recesses extending from the surface, the cylindrical plugs having annular flanges at their lower ends and inserted into said recesses, the spiral springs resting at the bottom of the recesses and bearing against the lower ends of the plugs, and the cylindrical sleeves secured in the recesses around the plugs, as and for the purpose shown and set forth.

3. The herein-described feed-roller for planing-machines, consisting of the roller A, having cylindrical recesses C, grooved longitudinally at I, the cylindrical plugs D, having an- IOO huhu' lzmges E et their lowel` ends, spiral my own I have hereunto affixed my signature springs F, resting in the bottom of J[he seid in presence o'ftwo witnesses. l recesses eyf'lndreal sleeves G, having Ilongil Y v y T tudnul ygloox'es', and hstening-selews H, :L11 ABRAHAM' ("ROSS 5 Constructed and combined to operate as and vWitnesses:
