IMPROVEMENT IN PLANlNG-MACHINES.

' Specification forming part of Lctterslatent No.- 75,984, dated March 24, 1868; reissue No, 4,737, dated February vertical section ofthe machine at its en d where the feed-rollers are located. Fig. 3 represents a side elevation of one end of the machine. Figs. et and 5 represent detail views of one of the brackets for supporting the vertical cutterhead spindles, and Figs. 6 and 7 represent detail views of one of the presser-blocks.

The nature of my invention consists in certain improvements in wood-planing machines, as hereafter described. The supporting fram ework of my improved molding-machine 'consists of two upright-side pieces, marked A in the drawing, which at suitable points are joined together by horizontal brace-rods or bars, and at their upper part by the bed-plate B, over which the stutf7 or wood passes to be acted upon by the cutter, whereby it is cut into form or molded. C C indicate feed-rolls, supported at each end in bearings a on the upper ends of vertical side pieces D of the feed-roll adjusting-frame E, composed of side pieces or plates D and F, together with their connections, the construction of which will be now described, as well as itscombination with the main frame A, and also vthe driving mechanism for operating the feed-rolls C. The side pieces D of the feed-roll adjusting-frame E are each provided with a dovetailed strip fixed to their in side faces. These are arranged to move in corresponding-shaped grooves formed in the plates F, which latter are in turn arranged to move in suitable ways or grooves formed npon the' outside faces of the main frame A. Beneath the bed B, and supported in suitable bearings in the lower part of the side pieces D, is a horizontal shaft, G, extending from side to Side of the machine, and provided at Aone of its ends, which projects some distance beyond the frame, with a pulley, H, on which i runs the belt for driving the feeding devices, as hereinafter described. through vertical slots c, formed for that purpose through the inner plates F. I indicates a horizontaly bar, extending across from one to 'the other of the outside plates D D, passing -spring K is fastened to the bar J by means of a screw-loop, L, the upper looped part ofwhich embraces the spring K, while the lower part thereof is passed through the bar J and provided with a nut, which is turned up against the bar to clamp the parts in position. A

screw-spindle, M, provided with a milled tiange or hand-wheel, d, for turning it, is arranged in a'vertical position through the bar J, which i latter is fitted with a female screw-thread to engage the thread on the screw-spindle M.-

The end of the screw-spindle M is arranged and secured in a suitable opening in a crossbar, A', which extends from side to side ofthe frame A, beneath the bed B, said spindle M being allowed to turn freely in the opening, while it is by means of the bar supported in position. By turning the spindle lVlthe crossbar J and feed-roll supporting-frame, together with the feed-rolls C, can be raised or depressed to adjust-the feed-rolls G to the thickness of the stuff to be molded or operated upon.

By arranging the side plates D and F of the adjusting frame E to slide one upon the other in connection with the spring K, the pressure or feed-rolls C are permitted to yield to any slight variations or. inequalities in the thickness of the material passing under them. The

feed-rolls U are provided at one end with similar-sized spur-pinions N, both of which mesh into aspur-pinion, O, whereby the pinions N are revolved, causing the rolls C to both turn in the vsame direction. The pinion O is at- The shaft G passes tached to the inner side of a spur-gear, P, and both are supported and turn together upon a center stud, P', projecting from the upperl'iart ot' one ot' the plates l). The gea-r P meshes into a pinion, Q, ixed tothe front side ot' a bevel-gear, lt, which latter two are supported upon a stud, R', that projects from the pla-te I) at a short distance below the stud P. A vertical shai't, S, is supported in suitable bearingsj'f on the outer side ot' the plate D, below the studs P Land lt, and said shaft S is provided with bevel-pinions T V at its ends, the upper one, T, to mesh with the gear R, and the lower one, V, to mesh with a similar pinion, XV, ixed to the end ot the pulley H, as shown in Fig. 2. The pulley H is arranged to slide upon its shaft G, and can be moved back and forth by a hand-lever, Il', to throw the pinion \V into and out ot' gear with the pinion V when desired. When said pinionsV and W are in gear the motion which is imparted to the pulley lI by the driving-belt is trans- Initted to the feed-roller C through the train ot gears and pinions above described. X indicates a bar t'or supporting and carrying the presser-shoe'Xl, used just in front of the cutter-head for' lirml y holding the stuff to the bed while it is being operated upon by the molding-cutters. rThis presser-shoe or foot Xl is the presser-foot embraced in and secured by Lett-ers Patent gran ted to me the 14th day ot' August, A. l). lbl, and therefore need not be more t'ullt,` described herein. "he ends ofthe bar X are secured to vertical plates X2, which are connected to inside plates and other parts whichare constructed and arranged ina similar manner to those described for supporting and adjusting the 'eedrolls C, and for a similar purpose-wiz., to support and adj ust the bar X and pressei-shoe X, and at the same time to. permit said shoe X1 to yield to the variatina ot thickness in the stutt' as it 'passes beneath. That portion B2 ot' the bed B over which the cutter-head Y is arranged to operate is provided with a series ot' slots or openings, I3', extending parallel with the direction in which the "stut'ti moves, and also with the sides of the machine. The openings are separated by shcrt bridgebars E', as illust ated in l. Bythis construction of the bed the cut-ters upon the cutter-head Y are allowed to i opera-te kup'on and perfectly mold or cnt the lower edges of the stut't' without striking the bed, and thus becoming injured, from the fact that the cutter can be arranged upon the head Y 4in such a manner that the openings D will receive their' ends as the head revolves, thus permitting them to pass below the upper surot' the block g and presses it against the opposite ange i, 'as shown in Figs. 6 and 7 The pressure of the spring can be adjusted by turning in the set-screw L at the side ofthe holder h. The holder h is clamped in any position upon the bar F by means of thefset-screwj, arranged in the upper part thereof', as indicated. K1 K2 indicatethe uprigh'scatter-heads, for working the sides of stuff as it passes through the machine. These heads are arranged, respectively, a-t the right and left sides of the machine, and are supported upon the upper-'ends of the vertical spindles L2. Each of these vertical cutter-head spindles L2 are provided with a similar supporting-bracket, M1, detailed views of which are given in Figs. 4 and 5. provided with a box-bearing, M2, in which the spindleL2 turns, and near its lower part with a socket-bearing, M, in which the foot ot' the spindle is retained, while the central portieri ot' the bracket, which connects the upper and lower bearin gs M2 M3, and is cast in the same piece therewith, is curved outward toV allow sutlicient space for the pulley L2, which is arranged upon the spindle L2, between the bearings M 2 MJ, as indicated. The lower extreinity ot' the bracket terminates with a screwspindle, m, and is provided with two nuts, an,

which are screwed up, one above and one bei low, against the slotted cross-bar N2, at the lower part of the frame A, for holding thelower portion ot' the bracket M1 in position, while they also assist in its adjustment. The bearing M2, or upper end of the bracket M1, is inclosed and supported in a-boX-slide, O2, 'arranged to move in a transverse opening, Z, across the bed-plate B, by which arrangement the side cutter-heads can be adjusted in position laterally, while by properly turning the nut-s u the brackets which support the heads can be raised or lowered to adjust the heads vertically.

independently ofthe cutter-head bearings, and' thus furnish a support for the stuit as it passes through the machine. Then it is not desirable to use the bridgaplates beneath the stuli' they can be placed atthe opposite sides ot' the cutter-heads, as indicated in Fig. 1, at the head K2; the plates will then be out of the way ot' the statt and still not be liable to become lost from the machine. T2 indicates a loose pulley. arranged at one side ot' themachine in a vertical position, at the inner side ot' the main frame A. This pulley serves for The upper portion of the bracket' is \\'hen the heads are adjusted ver `tic-all y the `bearing M2 moves up or down withinl the slide-box U2, the bearings M2 M3 and guiding the belt by which the upright' cutterheads are driven, so that bothv cutter-heads can be operated in the proper directions by a single belt from a counter or other drivingshaft arranged at the rear end of the machine.

The belt extends from the pulley of the counter-shaft to and around the loose pulley T2;

` from thence back to and around the pulley L3 ofthe cutter-head K2; thence forward to and around the pulleyl L4 of the cutter-head K1,
