Specification of Letters Patent.

Patented J une 6, 1916'.

Application led February 3, 1913. Serial No. 745,925.

To all 'whom t may concern Be it known that I, PETER A. SOLEM, 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 Planing Machinery, of which the following is a specification.

My invention relates to wood planing machinery employing a side-head or heads, of which so-called planing and matching machines, flooring machines, and molding machines may be instanced as examples.

It is the object of my invention to provide novel means for mounting the upright shaft to whichcthe side cutter-head is se cured; further to provide novel means for adjusting the side-head or heads vertically;

further to provide novel means for support- I ing the side-head hanger or hangers; further to provide novel clamping means for the same; and further to provide novel contact-means for the stock.

It is the object of my invention further to provide a novel construction and mounting for the side-head hanger or hangers whereby ready removal of the shaft-bearing parts is accomplished; further to provide novel adjusting and clamping mechanism for the sidehead hangers whereby either or both of said hangers may be adjusted or clamped from the outside of the machine; further to provide novel means y for supporting the upright cutter-head shaft and adjusting the same; further to provide novel clamping means for releasing or clamping either side-head hanger independently of the other side-head hanger from the outside of the machine-frame; and the invention will be further readily understood from the following description and claims, and from the drawings, in which latter Figure 1 is a front end elevation of my improved device, the frame of the machine being shown in cross-section. Fig. 2 is a side elevation of the same. Fig.` 3 is a side elevation of the right-hand hanger and its attendant parts, the parts between the hangers being shown in section on the line 3 3 of Fig. 1. Fig. is a plan view of my improved device. Fig. 5 is a vertical axial section taken on the axial line of the cutterhead shaft of the left-hand hanger, on the line 5--5 of Fig. 1. Fig. 6 is a horizontal cross-sectional bottom view of my improved device, taken on a line corresponding to the line 6-6 of Fig. 1. Fig. 7 is a cross-section on the line 7 of F ig. 3, showing Vthe clamping means for the side-.head hangers and the upper and lower stock-positioning means. Fig. 8 is a detail in section on the' line 8-8 ofF ig. 2 showing the means for end-positioning the clamp-shafts; and', Fig. 9 is a detail in section von the line 9 9 of Fig. 4, showing the adjusting'means for the stationary chip-breaker and the means for securingV the matcher-leg to the matcher- Y plate.

nism, such as power driven feed-rolls, for Y feeding the boards or stoclr past the cutterheads.

11 represents the main frame ofthe'machine, which is arranged tosupport the horizontal cutter-head or heads andthe feeding devices in suitable manner, and

. which may also contain a table 12 on which the stock is arranged lto be fed in the ma chine in the direction of the arrow a.

Side-head hangers 13, 14C, also known as matcher-hangers are mounted in the machine. I shall designate the left side-head hanger as 13 and the right side-head hanger as 14, either one or both of which may be employed. These side-head hangers are to a great extent duplicates of each other and in describing the parts of one which are duplicated inthe other, I shall refer to the duplicated parts by similar but primed reference numerals, the description referring primarily to thel left-hand hanger.

The side-head hanger, as shown, comprises a plate 15, hereinafter also termed a matcher-plate, a leg 16, and a bearing-yoke 17. The plate is slidable laterally between guides 18, 19, rigid on the main frame, and shown on cross-girts of the same. (See Figs. 2, 3, 4e and 5.) vThe guide 18 is shown as a dovetail guide with which a guideway 20y on the plate 15 coperates. 'Ihe guideway 20 comprises closely adjacent front and rear walls for forming a narrow and long guide- Y ates.

guide for preventing swveling of the plate and for maintaining the plate parallel with the guide during the adjustments thereof and causing the plate to move in true lines with relation to the guide. lThe front wall of the guideway is shown formed by a strip 21 secured to the plate. (See Fig. 1.) rf lhe guide 19 is shown as aflat guide, with which a guideway 22 on the plate coper- The guideways extend preferably across the width of the plate.

25 is a clamp-slice arranged to clamp the plate in adjusted positions. (See Figs. 2, 3, 5, 6 and 7.) It has a clamping face 26 which coacts with the cross-girt on which the guideway is located. rlhe clamp-shoe preferably extends a substantial distance across the width 0f the plate. A clampscrew 27 is threaded into a threaded bearing 28 in the plate and journaled in a bearing 29 in the clamp-slice. A spiral-gear 3() is secured to the clamp-screw, the clamp-shoe being received between said spiral gear and the plate for being clamped therebetween, the clamp-shoe having a ridge 31 thereon which impinges the plate.

The clamping face of the clamp-shoe is preferably interrupted at the screw position, see the interruption 32, Fig. 7, so that clamping effect is insured at points distanced from said screw toward the ends of the plate, for distributing the clamping eifect over a larger area. In this manner, further, three clamping points are provided for the clamp-shoe, namely, the ridge and the clamping faces adjacent the respective ends of the clamp-shoe.

Each of the side-head hangers is provided with a clampand each of the clamps is independently operable, preferably from the outside of the machine, so as to independently' clamp the side-head hangers rigidly in the machine in order that either sidehead hanger may be adjusted independently of the other and clamped without affecting Y the adjustment or clamped relation of the other. By providing these independent clamps I avoida disarrangenient of adjustment which would otherwise result from mere unclamping of a side-head hanger and reclamping of the side-head hanger without adjustment of the same. The clamping is effected by a clamping force exerted in a direction at substantial right angles to the plane of the guiding face, so as to reduce the tendency of .disarrangement of adjustment to the minimum, the guiding and clamping being -effected preferably at opposite sides of the cross-girt.

For operating the clamps, shafts 35, 35, are provided, with. which spiral gears 36, 36', have spline-connection, as shown at 37, 37, the said spiral gears having hubs between bearings 39, 39, in depending lugs 40, 40, depending from the plates 15, 15,

the said shafts being j ournaled in said bearings. The spiral gears 36, 86, Vmesh with the spiral gears $50, 30. The clamp-shoes are guided by said lugs to prevent swiveling motion et the shoes. The shafts 35, 35', are journaled in bearings 41, 41', (see Figs. 2 aud S), in the side of the main frame and have means thereon for turning the same,

shown by the squared ends 4&2, 42', arranged to receive a suitable crank-arm 46 for turning the shafts. longitudinally by collars 43, 43, thereon, received in said bearings, the outer parts of said bearings being formed in an outer cap 44 releasably secured to the frame by a bolt 45.

The leg` 16 of the side-head hanger is releasably secured to the plate 15 by bolts 47, and has a positioning connection 48, shown as a tongue and groove connection, for positioning the depending leg in line with the guideways of the plate. (See Figs. 4 and 9.) The bearing-yoke 1T is adjustably mounted on the leg and has bearings 49, 50, thereon in separated relation for an upright shaft 51, to which a side-head is suitably releasably secured, and having an operating pulley 53 between the bearings.

is a guide for the lower end of the legs, this guide extending orosswise of the ma chine, the legs being provided with coacting guideways 57, 57', one of the walls whereof is formed by a clip 58 releasably secured to the leg by bolts 59'. The guide 56 is releasably secured to the main frame by bolts GO.

For moving the side-head hangers laterally on their guides 1 provide adjusting screws 61, 61. (See Figs. 1, 2, 5 and 6.) The adjusting screw 61 has threaded connection in a bearing 62 in the leg 16 and the adjusting screw 61 has threaded connection in a bearing 62 on the leg 16. Upon lateral adjustment of either or both the side-head hangers, the same are clamped in place by means of the clamp-shoes 25, 25', in the manner hereinbefore stated. The adjusting screws G1, G1 are longitudinally positioned by collars G3, (33 thereon, received in bearings 64, 64', whose outer ends are formed by a cap 65 secured in place by a bolt 66, similar to the end-positioning means of the shafts 35. The outer ends ofthe adjusting screws are provided with turning means, shown as squared ends G7, 67', arranged to receive a suitable socket-crank, similar to the part 46.

The manner of rsupporting the side-head hangers by supporting the plates of the saine at front and rear in guideways and providing a guideway at the front of the lower end of the same, provides a three-point support for each of the side-head hangers, the principal support being obtained from the front and rear guides at the top of the same, the

rhe shafts are positionedl guide at the bottom being a steadying support. The manner of clamping the sidehead hangers in place after adjustment permits the clamping action to take place with minimum disarrangement of the adjusted positions of the side-head hanger.

The bearing-yoke is adjustable up and down on the depending leg, the leg being provided with a guideway in which a guide '71 on the bearing-yoke has sliding movement. (See Figs. 1, 2, 5 and 6.)

72 is a screw-rod journaled in a bearing 73 on the leg and having threaded connection in a bearing 74 on the bearing-yoke. A spira-l gear 75 is secured to the screw-rod, a collar 76 preventing endwise movement or' the screw-rod in its bearing 73. A spiral gear 77 has a hub 78 ournaled in a bearing 79 on the leg and meshes with the spiral gear 75 for operating the same. A collar 80 on the hub prevents endwise movement of the hub. Operating shafts 84, 84, are provided or the spiral gears 77, 77. These respectively have spline-connections S5, 85, with said spiral gears. The shaft 84 also passes through an opening 86 in the leg 16, and an opening 86 in the leg 16 provides clearance for the shaft 84.

The operating shafts 84, 84', are journaled in bearings 87, 87, and at their' outer ends are provided with operating means 90, 90', shown as squared ends of said shafts, adapted to receive a usual crank-handle for turning the same, similar to the part 46. These operating shafts are located in endwise positions by means or' collars 91, 91, in said bearings, the outer portions of said bearings being in a cap 92 releasably secured to the main frame by a bolt 93. Upon removal of the cap the operating shafts may be removed endwise from the machine.

96, 96 are shaving-hoods received about the cutter-heads, the shaving-hood 96 being releasably pivoted on a pin 97 secured on the plate 15. this shaving-hood having a chipbreaker' 98 thereon adjustably secured thereto, the stem 99 thereof being slidable in a socket 100 of the shaving-hood and secured in place by a set-screw 101. The shavinghood 96 is releasably secured to the plate 15 by bolts 102. The swinging shavingchute and chip-breaker are held against the stock by means of a weight 103 secured to the swinging shaving-chute at 104 by means of a flexible connection 105 passing over pulleys 106, 107.

110 is a hold-down bar adjustable up and down on a standard 111 on the plate by means of an adjusting screw 112 journaled on the hold-down bar in a bearing 113 and threaded into `a bearing 114 on the standard, there being a guiding connection 115 between the hold-down bar and standard. A bolt 116 threaded into the hold-down bar and received through a slot 117 in the standard rigidly secures the parts in adjusted relations. i

The standard is adjustable crosswise of the plate, having guiding connection 118 therewith, being adjusted by means of an adjusting screw 119 journaled in a bearing 120 on the plate and threaded into a threaded bearing 121 of the standard, a bolt 122 being received through a slot 123 in the base of the standard and threaded into the plate for securing the parts inradjus'ted relations. The lower portion of the inside face of the standard acts as a side-guide for the stock. The hold-down `face 124 of the hold-down bar is located between the upper guides of the hanger, the adjusting means therefor being located substantially above one of said guides.

I prefer to provide a lower bridge-piece 126 coperating with the hold-down bar. This bridge-piece is arranged to support the lateral edge of the stock while passing the side cutter-head, and will be described with particular' reference to the right-hand hanger. (See Figs. 3, 6 and 7.) The bridgepiece is adjustable up and down on an apron 127 depending from the plate 15 and clamped in place by means of bolts 128 received through slots 129 and threaded into said apron, the adjustment being effected by means of a. set-screw 130 threaded into a bearing 131 at the lower end of said apron and locked in place by a lock-nut 132 and bridge-piece being supported between the front and rear guides of the matcher-plate, and received in a recess 133 at the inner edge of the matcher-plate. The standard 111 has a recess 134 for accommodating the support. This adjustment raises and lowers the bridge-piece with relation to the stock-supporting face of the table, which is important especially where a formed cutter, such asa tongue or groove cutter, is being employed on the side cutter-head, and further permits the taking up of wear which may be occasioned by the passing' of stock over the stock-supporting face of said bridge-piece. Locating said hold-down bar and the bridgepiece betweeny front and rear guides at the top of the hanger affords an especially rigid construction in which vibrations are reduced to the minimum` and is especially valuable in high-'speed machines.

The stock is arranged to be fed .against a side-guide 136, whose guiding face is in line with the guiding face at the lower end of the Standard 111. This side-guide is adjustable laterally. There is a stationarily positioned chip-breaker 137 at the feed-in side of the right-hand cutter-head adjustable toward and from the cutter-head in lines parallel to and at right angles to the lines ot feed of the stock. It is preferably mounted on a support 138 which may be part of the side-guide having connection therewith by ivoVV a web 139. Lateral adjustment is provided by means of a set-screw 140 bearing against said support and having threaded connection in a lug l-ll on the plate, a bolt 142 passing through a slot 11i-3 in said support and threaded into the sheltl for-clamping` the support in place. The chip-breaker 137 has a guideway 14e-i cooperating with the guide 1&5 on said support for adjusting the chipbrealer parallel to the line of feed of the stock, a bolt 146 passing through a slot 147 in the chip-breaker and threaded in a tlneadedbearing in saidsupport, clamping the parts in place. By these means a laterally adjustable side-guide is provided above each top guide of the hanger, respectively at front and rear of the cutter-head, a coperating edge support and hold-down, having up and down adjustment, being located between said side-guides and said top hangerguides.

My improved device provides ready means for removing the bearing-portions of the side-head shafts and for readily replacing the same in correct positions. This is accomplished by removal of the caps and. 92, whereby the adjusting shafts may be turned and moved longitudinally for disconnection with the legs. The bolts 59 and clips 58 are removed, whereupon the lower ends of the legs may be swung forwardly and the legs and bearing-yokes thereon removed through the bottom of the machine.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:
