FEED WORKS FOR WOOD WORKING MACHINES. No. 416,549. Patented Dec. 3, 1889.

UNITED STATES PATENT OFFICE.

EDIVIN BENJAMIN, OF SOUTH EVANSTON, ILLINOIS, ASSIGNOR TO THE BEN- JAMIN MACHINE COMPANY.

FEED-WORKS FOR WOO SPECIFICATION forming part of Letters Patent No. 416,549, dated December 3, 1889.

. Original application filed December 18, 1388, Serial To aZZ whom it may concern:

Be it known that LEDWIN BENJAMIN, of South Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Feed-Works for WVood-Working Machines, of which the following is a specification.

My invention relates to the feed-Works of planers or other wood working machines [0 which are capable of working two pieces of lumber at once, the upper feed-rolls being divided or broken that is, made in two sectionsso that each may yield independently.

My present invention relates to the devices for suspending and adjusting the upper feedrolls, such other patentable features as may be shown forming the subject of my patent No. 412,451, October 8, 1889, and a divisional application filed contemporaneously herewithto wit, July 22, 1889, and numbered 318,267the last-named application and this being divisions of the first.

In the accompanying drawings, Figure 1 is a vertical section of the feed-works of the machine, taken lengthwise of the bed. Fig. 2 is an end elevation of the feed Works, the bed being shown in section. Fig 3 is a perspective of one of the cross-braces, and

Fig. 4 is a section of one of the top broken rolls.

The top rolls 2O 20, Figs. 1 and 2, are carried by the frame-work or housing composed of the side pieces 7 7 and cross-braces 9 9, the

3 5 outer ends revolving in boxes 8 8 in the side. pieces 7, springs 10 10 (shown in dotted lines in Fig. 2) being placed over said boxes. The inner ends of the rolls are carried by hangers 21 21. (Shown partly in full and partly in No. 293,127. Divided and this application filed July 22, 1889. Serial No.

cess in the middle of the cross-brace 9, in which they are inserted. The lower end of each hanger 21 forms a journal-box for the inner end of the shaft of a roll 20, and to its 5 upper end is attached the bolt 22, by which it is suspended from the cross-brace 9. The nut at the top of the bolt 22 provides for the adjus'tment of the alignment of the rolls 20, and the spring 28 surrounding the bolt 22 exerts an elastic pressure on the hanger 21. Thus each roll 20 is capable of yielding independently within certain limits.

The frame carrying the broken rolls, consisting of the side pieces 7 7 and cross-braces r. 5 9 9, is also constructed so as to yield as a whole in case the yielding of the broken rolls is not sufficient, being connected by means of an adjusting screw and bolts to a weighted lever attached to the lower part of the planer, as shown in the drawings. For the reason that the present application is not concerned with the special construction of these devices for permitting the said frame-work to yield, a detail description thereof is not given herein.

I claim- The combination, in a wood-working machine, of side pieces fitted to standards attached to the bed cross-braces connecting said side pieces and having a recess at their middles, hangers adjustably suspended in said recesses by bolts attached thereto and passing through the top of said cross-braces, springs upon said hangers and surrounding said bolts, top rolls supported in said hangers 7 5 and in boxes in said side pieces, and springs over the last-named boxes.

EDWIN BENJAMIN.
