WOOD-PLANING MACHINE.

SPECIFICATION forming part of Letters Patent No. 398,048, dated February 19, 1889.

Application filed January 30, 1888. Serial No. 262,396. (No model.)

.To all whom it may concern:

Be it known that we, ALFRED B. I-IUTOHIN- soN and ERNST F. AUTENRIETH, both of Brooklyn, (Green Point,) in the county of Kings and State of New York, have invented a new and useful Improvement in Wood-Planing Machines, of which the following is a specification.

The invention will be hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a portion of ainachine embodying our invention. Fig. 2 is a transverse section upon the plane indicated by the dotted line z 2, Fig. 1. Fig. 3 is atrausverse section of an upper roll-frame, whereby the two sections of an upper feed-roll are supported upon the plane indicated by the dotted lines: :0,- Fig. 2.

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

A designates the side frames of the machine, and B designates an upper cutter-head. The journals 1) of this cutter-head are fitted in boxes 1') upon a cutter-head frame, B, which has brackets or flanges 11 bearing upon the cutter-head stands A, which rise from the main frame A. The cutter-head frame B may beadj usted upward and downward upon the stands A by any of the means usually employed for this purpose, and we have not shown such adjusting means, as our invention in no'wise relates thereto. The cutterhead B is driven by a belt, 19 from a pulley on the usual counter-shaft, B which is at the front or feeding end of the machine. Upon the front side of the cutter-head B is a bar or mouth piece, B which extends across parallel with the cutter-head and which is adjustable in the cutter-head frame B. Such adjustment may be accomplished by means of screws 1)" Upon the opposite or rear side of the cutter-head B is a bar, B", which constitutes a chip-breaker and which is adjustable upward and downward. This chipbreaker is supported from the cutter-head frame by means of arms or links I), which have circular eye portions 0 embracing circular hubs concentric with the cutter-head bearings B. The ends of the chip-breaker are secured by screw-and-slot connection to the arms or links I).

Behind the cutter-head B we have represented two pairs of feed-rolls, which are upon the opposite sides of standards A rising from the main side frames, A. These standards A have in them slots (1, for a purpose hereinafter described. The lower rolls, C, of the two pairs are journaled in stationaryboxes cf, and the upper rolls, C, are each composed of two sections, or, in shop parlance, are broken, as best shown in Fig. 2. The sections of the upper rolls, C, are mounted in boxes 0 c and the boxes of each of said upper rolls are supported in an upper roll-frame, C ,which extends transversely of the machine, as best shown in Fig. 2. The upper roll-frame, C has at opposite ends sockets or eyes 0 which fit rods 0 C at opposite sides of the machine.

The rods C at the side of the machine opposite to that which is shown in Fig. 1 are simply smooth cylindric rods supported at their lower and upper ends in bearings or rests c, and which serve simply as guides ment of these screws is prevented by collars 0 upon them resting upon their bearings 0 but when the upper roll and its upper rollframe, C are lifted, the corresponding screw C is lifted. Each upper roll-frame, C is connected at opposite ends by rods d with arms d upon a rock-shaft, D or D. As here represented, both rock-shafts D and D are concentric, the latter being tubular and journaled upon the former. The arms 61 of one rock-shaft extend in one direction to the rods cl, by which they are connected with one upper roll-frame, and the arms cl of the other and are loaded by springs Zia rock-shaft extend in the opposite direction to corresponding rods (7, whereby they are connected with the other roll-frame, Consequently it will be understood that whenever either screw is turned by a handle, c applied to its upper end both ends of the roll :t'rame C will be raised equally, because of their connection with the one rock-shaft.

\Ve do not; claim as oi our invention the comlilination, with the upper rolls of two pairs, of the two concentric rock-shafts, one surrounding the other, and which are connected by arms and rods, one with each of the upper companion section C may bear upon the roll-supports, as such subjectanatter is ineluded in the application of James F. elch, Serial No. 2ti2,'l0t), tiled January 97, 1888.

The lower endsot' the screws (1' are prolonged downward below th eir beari n and,

as here shown, have connected with them a l yoke, and (1 designates a weighted lever, which is t'ulcrumed at c, and which is hung by a stirrup, upon the yoke This arrangement oi weights being applied to the screws is, through the connection of each upper roll-frame, (.7 at its opposite ends with one rock-shaft, distributed upon both ends of each upper toll-frame, C

The boxes 0 0 in which the sections of each upper roll, (2, are journalcd, have a limit-ed verticzll movement in theupperroll-frame, C Each of the outer boxes, 0", is arranged in a slideway, e, and has bearing upon it a spring, 6, whichis in a cupshaped cavity, 6" in the roll-frame, and is here shown oli' india-rubber. Above the spring c is an adjlisting-screw, c, and by setting this screw (flownward the spring 6' may be caused to act with greater force upon the box c'. The center or inner boxes, 0 are supported in a slidcway, 0*, and are limited in their upward movement by stop-bolts 0.

Above them is a s )ring, e'flwhich is arranged in a cu p-shaped cavity, c, in the upper rollframe, and which is controlled or adjusted by a screw, c". here represented as a spiral spring of steel, is a t'olltnvcr or plate, c and through a toggle-link, c, and a saddlepiece, e", the force of the spring c is distrilnit'ed upon the two inner roll-Frame boxes, clwhich are at the adjacent inner ends of the sections of the upper roll, t", as shown in Fig. 2. The link or knuckle has rounded or knuckle-shaped bearings upon both the disk or follower e and the saddle-piece c, and consequently the force of the spring 6 is applied equally to both the adjacent boxes (5 and either box may rise to the extent permitted in the frame C without disturbing or causing the other box to rise. The movement which the boxes c e have in the upper roll-t'rame is very limited, and need be only about onequarter or three-cighths of an inch. 'When the boxes 0 c are maintained in their lmvermost position in the frame C it true that: the weights which are applied to the roll-frame have no direct effect upon the boxes; but: the springs e c with llelow the spring 6, which is panion section (.1, instead of being raised therewith, will bear upon the lumber of least thickness, and will therefore feed it straight; through the machine; also, when two boards or pieces of slightly unequal. thickness are top in, the one roll-section C may rise by its contact with the thicker lumber, while the thinner board or lumber and feed it properly along.

Upon the lower rolls, (f, are pinionsfnvhieh are geared together by an intermediate wheel,

f, and upon one of the lower rolls, L, is also 7 a larger gear-wheel, f which is in gear with a driving-pinion,f which may be upon what is usually termed the pinion-shaft I oi the machine.

Inasmuch as the upper rolls, t", are broken, it is necessary to drive positively the two sec tions of each roll. lVe therefore provide a shaft, F, intermediate between the two upper rolls, and which is supported in bearings f, extending inward from one of the upper roll-frames, O

The shaft h" is received in the slots a, formed in the standards A and consequently it is free to rise and fall'with the upper roll-frames, C Upon each of the sections of each upper roll, 0, are pinions or wheels f, both of which are in gear with corresponding pinions or wheels, f, upon theintermediate shaft, F, and consequently if to tary motion is transmitted to the shaft F the sections of both the upper rolls will be individually driven therefrom.

Upon one of the lower rolls, (.1, at its end. opposite the connecting-gears ff is a pinion,

,f", and upon a correspont'ling end of the intermediate shaft, F, is a wheel or pinion,f Gearing with both said wheels f f is an ex pansion gear or wl1eel,f-", which is supported by swinging links f from the shaft F and from thc'lowcr roll, C, on which is the wheel Consequently, no matter what the rising or falling movements of the shaft F and the upper rolls, motion is always transmitted through the wheels/" f f to the upper shaft, F, and thence to the upper rolls.

\Ve make no claim, broadly, to the arrange ment and construction of the expansion-gear ing here shown to transmit motion to the upper roll or to the wheel or shaft geared with the upper rolls of two adjacent pairs, as such subject-matter lin'oadl y elaii'ned in the aforesaid application of James F. \Velch; but we limit our use of such expansion-gear to its combination with upper rolls each composed of two sections and an intermediate shaft between the two upper rolls and which is geared with the sections of each roll.

hat we claim as our invention, and desire to secure by Letters Patent, is-

l. The combination, with a lower feed-roll, journaled in stationary bearings, of an upper roll composed of two sections arranged end for end, an upper roll-frame in which both sections of the upper rolls are journaled at each of their ends, said frame comprising sockets at the ends thereof and made integral therewith, one of said sockets forming a nut, two vertical rods, one at each side of the machine, and one of which is a screw e11- gaging said nut, a crank for rotating said screw so as to bodily raise and lower the rollframe and the upper roll-sections journaled therein, journal-boxes for the upper roll-seetions supported wholly in said frame and capable of a limited vertical movement therein, said journal-boxes being acted upon by springs to press them downwardly in the frame, substantially as specified.

2. The combination, with the lower roll, C, and the upper roll-sections, O, of the upper roll-frame, C the boxes for the roll-sections having a limited vertical movement in said frame, the springs 6, whereby the outer boxes are held down, and the springs e, and a sad dle whereby the two inner boxes are held down, substantially as herein described.

3. The combination, with two pairs of upper and lower rolls, the lower rolls being journaled in stationary bearings, and the upper rolls being each composed of two sections, of an upper roll-frame for the sections of each roll, and boxes for the roll-sections having a limited vertical movement in said frame, a shaft intermediate between the upper rolls and geared with the two sections oi each upper roll, and journaled in bearings projecting from one of the roll-frames, gearing connecting the lower rolls of the two pairs, and expansion-gearing connecting one of said lower ends thereof, one of said sockets forming a nut, two vertical rods, one upon each side of the machine, extending through said sockets, one of said rods being a screw and engaging a screw-thread in its coacting socket, a crank whereby said screw-rod may be moved up and down in order to bodily raise and lower the frame and the upper feed-roll section, a rockshaft having arms connected by rods with the ends of said upper roll-frame, a weight applied to said rods, and boxes for the upper roll-section having a limited vertical movement in said frame, and which are acted upon by springs to press them down in the frame, substantially as specified.
