WOOD-PLANING MACHINE.

SPECIFICATION forming part of Letters Patent No. 223,851, dated January 27, 1880.

l Application filed September 3, 1879. i

To all lwhom 'it may concern Be it known that I, LUGtUs P. HOYT, of Aurora, Kane county, State of Illinois, have invented certain new and useful Improvements in Tood-Planing Machines, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure 1 is a plan View; Fig. 2, a cross-section on line x .r of Fig. 1; Fig. 3, a longitudinal section on liney y of Fig. 1; and Fig. 4, a longitudinal section on the border-line z of Fig. l. 1

Theobject of this invention is to improve the action of the upper portion ot' the holding and feeding' drivers by making them more yielding, so as to improve the action on uneven boards; and also so that two or more boards may be run through the machine at the same time, and its natureconsists in combining a yielding pressure-bar and a yielding roller with sectional or divided and separately-yielding presser-feet, with a traveling feed-bed or feed-roller, and in the several parts hereinafter described and claimed as new.

In the drawings, A indicates any ordinaryT or suitable supportingframe 5 B, the usual traveling feed-bed; O, the cutter-head 5 D, the presser bar`or fran1e;.E, the presser-roller; F, the inclined supporting-frames for pressure roller and bar; G, the end plates or frames of the pressure roller and bar; S, a strip or board placed in the machine, illustrating the action of the presser-feet; a, the cap-plate of the presser-bar; b, the presser-feet springs; c, the presser-feet stems 5 d, the presseri'eet; e, the front, and fthe rear, inclines of the presserfeet 5 g, the pressure-bar springs .5 h and i, setscrews for adjusting the space Within which the pressure-bar D may rise or fall 5 j, guideblock in the frame or inclined guide F, and l and m cap-plates. y The cutter-head C is made in any of the usual .modes or forms, and-is supported upon the ing against their upper ends andthe cap-plates l. The plates or frames G are attached to the blocks j, and are provided with openings forV the reception ot' the ends ot' the bar D, and furnish thejo'urnal-bearings ofthe roller E. By this arrangement ofthe supports of the presssure bar and roller on the blocks j the two rise and fall together when a movement takes place, and the blocks being supported in inclined guides, as they rise they recede from the cutter-head, and as they descend they advance toward it, so that the ends e ot' the presserfeet can be kept close to lthe cutters and act as chip-breakers without coming in contact with the cutters.

The bar D may be made as shownthat is, a single bar with recesses-or it may be made .in parts, constituting a frame when together.

It is secured at the ends in the plates G, so as to be free to rise and fall therein, and is held down by the springs g, which are located upon or partly Within it, and are held down by the caps m. The lowest point of descent is regulated by the set-screws i, and the rise is liniited by the set-screws h. By this arrangement the bar D has a yielding' action ot' its own, and can also be adjusted so as not to interfere with the introduction of the boards, and so that it cannot rise high enough to bring the feet el against the cutters. rlhe bar or frame D is chambered or recessed along its length for the reception of the legs or stems c of the presserfeet. These legs are made with a head and stem, both fitted to their openings, so as to have the least binding action in their movements. They are held down by the springs b pressing between their heads and the cap-plate a. As shown, the cap a is a single piece, eX- tending the length of the bar between the caps m,- but in actual use it may be made in sec-r tions, so that each presser-foot spring .mayhave its separate cap.

The feet d are attached to the stems by having the stem pass through them, so as to make a strong connection, which is not liable to be broken or disordered. These feet fit against and support each otherlaterally, while they are free to rise and fall separately within the limits of travel, and they are pointed or beveled at the ends, as shown at c and j'.

By this arrangement of the feet with' the bar D they not only have a separate :and inde- IOO pendent yielding action, but they also have a d, and the yielding roller E, constructed and united action, as they may'rise or fall together by the yielding action of the bar or frame D; and by having the roller E journaled in the same end pieces and acting Without any rocking movements the heavier pressure is taken by that' roller which has a yielding movement under the spring 7c, the pressure from the pressure-bar D and feet d is so far relieved that it can be made much lighter, and the en tire pressure distributed among the three sets of springs b, g, and 7c, acting upon separate parts of the presser devices.

I have shown eight presser-feet; but the number may be varied according to the Width of the machine or the special use for which it may be designed.

The arrangement of a yielding` roller and a yielding presser-bar, both having the same movement, and the pressure-bar having an additional and independent yielding` movement, will be found useful even when not used with a sectional or divided set of presser-feet, and 1 do not thus limit this part of my improvement.

Vh-at I claim as new, and desire to secure by Letters Patent, is-

l. The combination of the yielding bar D with two or more independently-yieldin g feet,

operating` substantially as specified.

2. The combination of the foot d, stem c, spring b, and cap a with the yielding bar D, substantially as described.

3. Thecombination of the frame or bar D, With the springs g, adjusting-screws h and i, with the plates G, to permit a slight move# ment of' the bar independently of the roller, substantially as set forth.

4. The combination of the plate G and block j, roller E, and frame D with the inl clined frame F and spring 7c, substantially as specified.

The combination of a yielding roller with a yielding pressure-bar connected to yield with the roller, and to have a separate yielding movement by mechanism, substantially as specified.

6. rlhe combination of the frames F, springs 7c, and plates G with the bar D, springs g, stems c, springs b, separate or divided presserfeet d, and pressure-roller E, all constructed and operating substantially as described.
