PETER A. SOLEM, OF CINCINNATI, OHIO, ASSIGNOR TO J. A. FAY & EGAN COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF VEST VIRGINIA.

WOOD-PLANING MACHINE.

To all whom it may concern Be it known that I, Perm: A. Sonmt, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Need-Planing Ma chines, of which the following is a specific. tion.

My invention relates to wood-planing machinery, and is principally applicable to wood-planing machinery employing a horizontally disposed cutter-head arranged to operate on the upper side of stock, whether said cutter-head is the sole cutter-head in the machine, or other cutter-heads operating for instance on the bottom or on one or more edges of the stock, are employed.

It is the object of my invention to provide new and improved relation of means whereby the chips caused by the cutter-head are removed; further to provide new and improved relation of means whereby the cutter-blades of the cutter-head may be jointed during operation of the machine; further to provide a shaving-hood and jointing means for the cutterhead located in such relation to each other and to the chip-breaker as to permit simultaneous operation of all said means, and the invention will be further readily understood from the following description and claims, and from the drawings, in which latter:

liigure 1 is a side elevation of my improved device showing so much of a woodplaning machine as is necessary to illustrate my invention. Fig. 2 is a vertical cross-section of the same taken on the line 22 of Fig. 1. Fig. 8 is a front view of the same. Fig. at is a top plan view of the same, partly broken away; and Fig. 5 is a sectional detail of the clamping means for the cutterhead housing taken on the line of Fig. 8.

I do not in this invention claim the positioning means for the cutter-head housing the same being claimed in a separate application, Serial No. 772598 filed June 9, 1913 divisional hereof, or the chip-breaker and its adjusting and controlling means, the same being claimed in a separate application, Serial No. 772110, filed June 6, 1918, divisional hereof.

11 represents the main frame of the machine, on which there are standards 12 having guides 13 thereon. A cutter-head hous- Specification of Letters Patent.

ing 14 has guideways 15 cooperating with said guides and has movement up and down on said guides. These mideways preferably have a bottom wall 17 and an end wall 18, plates 19 being secured to the end walls 18 by bolts 20. The cutter-head housing is adjusted to elevation by means of screw-rods 25 threaded in nuts 26 in the housing and j ournaled and held longitudinally stationary in bearings 27 in the main frame, and have bevel-gears 28 fast thereon.

29 is a cross-shaft journaled in bearings 30 in the main frame. Bevel-gears 31 are fast on the cross-shaft and mesh with bevelgears 28, the cross-shaft being provided with a squared end 32 arranged to be received in a suitable socket-wrench for turning the same.

The cutter-head housing is clamped in adjusted position by clamp-screws 36 (see Fig. 5), journaled in bearings 37 in the plates 19 and threaded in bearings 38 in the bottom wall 17, passing through slots 35 in the guides 13. A set-nut 39 and a jam-nut 10 are screwed about the outer threaded end 41 of each of the clamp-screws. The clampscrews are turned by arms 12 (see also Figs. 1,3 and 1) having splilie-connection with the clamp screws. This splineconnection is shown accomplished by a key .1-3 in the clamp-screw received in a spline-groove 4st in the hub 45 of the arm 42.

The arms at the respective ends of the cutter-head housing are connected by links l6 having articulation with said arms at 17, arms 48 extending from the hubs 15, the arms being connected by a link 19 articulated therewith by articulations 50. The arms 48 have hand-grips 51 thereon.

A cutter-head 55 is journaled in bearings 56 in the cutter-head housing or support. it is arranged to carry suitable cuttenblades, instanced by the cutter-blades 57.

(51 is a chipbreakcr before the cut of the cutter-head, which may comprise a chipbrcaker foot (32 adjustable on the body (53 of the chip-breaker toward and from the cutter-head. The foot has a toe (34. This adjustment is shown accomplished by providing a guideway (35 between the body and foot of the chip-ln'eaker. (See Figs. 2 and 3.) A set-screw ($6 at each end of the chipbreaker is adjustable in a threaded bearing 67 on a lug (38 on the foot (32 and is locked in ing formed by plates adjusted position by a lock-nut 69, the vend of the set-screw bearing against a lug on the body of the chip-breaker. The chipbreaker foot is clamped to its body by means of clamp-screws 71 received through slots 72 in the body and threaded into threaded bearings 73 in said foot. Means hereinafter described are provided for limiting approach of the toe toward the cutter-head. The chipbreaker has sliding connection at each end thereof with the cutter'head housing, shown in the form of guides 75 on the body of the chip-breaker sli'dable in guideways 76 in the housing, one wall of the said gnideways be- 77 rigidly secured to .the housing by bolts 7 8. The toe 64 of the chip-breaker is provided with a stock-contacted face 7 9 closely adjacent to its chipbreaking edge, parallel with the plane of the feeding face of the stock-support 82 and with a forward end wall 80 parallel to the right line movement of the chip-breaker caused by the guides 75 and guideways 76. The cl'iip-breaker foot has an upwardly slanting stock contacted sole 81 arranged to be contacted by the end of stock having a wide range of varying thicknesses.

For the purpose of resiliently resisting rising movement of the chip-breaker, I provide double-link yo- kes 91, 92, the doublelink yoke 91 comprising the links 93 having a crosspiece 94 integral therewith. The double-link yoke 92 comprises the links 95 having a cross-piece 96 integral therewith between the same at one end thereof. The double-link yoke 91 has bearings 97 at one end thereof, in which journal-bolts 98 are 'journaled, the journal-bolts having threaded connection in the bearings 99 of the body of the chip-breaker. The double-link yoke 91 further has bearings 100 at its other end, in which journal-bolts 101 are journaled, these journal-bolts having threaded connection in the connected bearing 102 at one end of the double-link yoke 92. The latter yoke further has bearings 103 at the other end thereof, through which a rod 104 extends, the rod further having support in the lugs 105 of the cutter-head housing.

111 is apivoted cup in which a spring 112 'is received, the cup being on a cross-piece 113 having trunnions 114 journaled in bearings 115 of the links 95. These trunnions are located nearer the pivotal connections of the links 95 with the housing than the pivotal'connections between the links 95and 93, whereby a minimum of movement of compression and extension of the spring will be caused by the movement of the links 95 in accommodating themselves to the changing positions of the chip-breaker.

A screw-rod 116 is threaded into a threaded bearing 117 in the cross-girt 118 of the cutter-head housing and is surrounded by the spring 112 and has a cup 119 adjacent its upper end adjustably positioned by a setnut 1.20 and a lock-nut 121.

A set-screw 122 is threaded into a threaded bearing 123 in the yoke 92 and impinges the cross-girt 118 for limiting the downward movement of the chip-breaker, and is locked in adjusted positions by a lock-nut 124.

Means are provided for sharpening or jointing the knives on the cutter-head while the same are rotating at full speed, so as to insure a smooth out being taken off the stock. I have shown this accomplished by means of a block 130 of suitable material, which acts upon the cutting edges of the cutterblades on the cutter-head during their rotation at full speed, this block of material, such as carborundum or other knife-sharpening substance, being moved lengthwise of the cutter-head during such rotation, it be ing understood that the cutter-blades have been previously sharpened and approXi-' mately set for causing the cutting edges of the cutter-blades to swing in as true a'circle as can ordinarily be effected by the usual setting and gaging mechanisms. The block is fastened in a slide 131, being clamped in the channel 132 thereof, by a clamp-screw or screws 133. The slide is movable up and down in a guideway 134 of a carriage 135 by means of an adjusting screw 136 journaled in a bearing 137 on the slide and held therein against endwise movement, and threaded into a bearing 138 onthe carriage, a spring 139 being located around the adjustingj screw between said bearings for causing recession of the slide from the cutter-head as far as the adjustment of the parts will permit, whereby lost motion is taken out for causing the ointing block to be backed by positive stops, namely, the screw and its bearings, and preventing further recession thereof during operation and preventing chattering of the block and consequently insuring that'the cutting edges of the cutter-blades be jointed in true lines at equal distances from the aXis'of rotation of the same and preventing any wavy or uneven action upon the cutting edges. The carriage 135 is slidable back and forth lengthwise of the cutter-head on a slide 140, secured to brackets 141'on the cutter-head housing, as by means of bolts 142 received through slots 143 in lugs 144 of said slide and threaded into the brackets 141, permit ting adjustment of the slide-with relation to the axis of rotation of the cutterlead for taking up any wear and insuringaccuracy of result. A rod 1.45 is preferably releasably secured to the carriage, as by means of a threaded connection 146, the rod having a handle 147 thereon, by means of which it may be moved lengthwise of thesli'de during 7 the cutter-head. It may be placed opposite one of the bearings of the cutter-head when not in use.

151 is a sl'iavingdiood, which has a month .152, extending preferably across the width of the cutter-head, at one side of the cutterhead and located at one side of the jointing means ust described. The mouth is arranged at that side of the cutter-head which moves away from the surface of the stock being planed, instanced as the teed-in side of the cutter-head, -t'or receiving the chips from that side of the cutter-head, and drawing in all the chips made by the Clli'tOP-llfitttl, for preventing the passage of said chips to the jointing mechanism, the mouth preferably o 'iening adjacent to the top of the honnet 15E} of the chip-brtniker. "he jointing device is located entirely outside the shaving-hood {or pern'iitting the operation of the jointing device without. action upon or dis arrangement of the hood, the jointing device being separated from the shavings passage of the shaving-hood by one of the walls of said hood, while the hood is also removable away from the cutter-head. The action of the shaving-howl, is to take the shavings from each individual blade before it reaches the jointing device, whereby no interrupt ion to the feeding of the board or stock through the machine need take place while jointing the knives. The shavings are removed by a current of air through the hood in the direction of the arrow 0. The shaving-hood preterably opens at one side of the cutter-head, the jointing device being slidable at the other side thereof.

For conveniently mounting and permitting removal oi. the shaving-hood I provide the same with a hook 155, which is received upon the rod 10 1-, and with lugs 156, one of these lugs being at each end of the shavinghood, and arranged to rest upon shelves 1.57 oi? the cutter-head housing, for positioning the hood with relation to the housing and permitting the mouth of the hood to be arranged as close to the cutterhc:ul as possible. The hood has telescoping connection 158 with the pipe 159 oi the blower-system for permitting ready movement of the hood up and down.

My improved device further provides ready means whereby the shaving-hood and the ointing device are located and operable side by side about the cutter-head, each being independently movable, the mouth of the shaving-hood being further so arranged with relation to the chip-breaker as to permit right line movement of the chip-breaker with relation to the cutter-head.
