FEEDINGi`l DEVICE FOR WOODWORKING MACHINERY.

, T all 'whom t may concern Be it known that I, PETER A. SoLiiM, 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 Feeding .De-y

vices for Woodworking Machinery, of which the following is a specification. f

It is the object of my invention to provide novel means whereby the' feed-roll or rolls in wood-working machinery have ro- "tation imparted to them for forwardly feeding the stock across a cutter-head, oifor reversing the direction of rotation of ysaid feed-roll or rolls for feeding ysaid stock in a reverse direction `for the purpose of withdrawing it from the machine; further to provide a swinging feed-roll housing with separate bearings for the feed-roll and with means for adjusting said housing to elevation and for adjusting said bearingsxon said housing for leveling said feed-roll; further to provide novel yielding arrangement for the housingby locating a spring 'above the housing diagonally between a relatively stationary part and the swinging housing,fthe

Vconnection between said spring `and housing being within the arc of swing of the axis of rotation of the feed-roll on said housing; further to provide novel link and cover mechanism for the feed-roll gearing;v further my improved device, the outer plates of the gear-covers being removed. Fig. 3 is a plan view of the saine. Fig. 4 is a horizontal section of the sametaken on the line 4-1 of Fig. 2, the reversingL mechanism being removed.

Fig. 9 is a vertical cross-section 9` of Fig. 2, showing one end of the upper and lower feed-rolls and the means for adjusting the same. Fig` 10 is a cross-section on the irregular line 10-10 of Fig. 2, showing the link and gearcover mechanism of the upper feed-roll gearing. Fig. 11 is a perspectiveview of the gearcover Vhaving the link-extension of the gearcover integral. therewith. Fig. 12 is an inside elevation, showing the means for supporting the bearing of the lower feed-roll.

Fig. 13 is a vertical section kon the line 5 2 of Fig. 2, showing the means at one sideof'the machine, for raising and lowering the upper feed-roll housing; and, Fig. 14: is an inside side elevation `of the lower portion of the same;

y11 represents ythe main frame, partly broken" away, of a wood-working machine, *asa planing, planing and matching, yor floorl ing machine, or machine of'similar character, embodying feeding mechanism and a cutting agency or` agencies, so much ofthe machine only being shown as is necessary toillustrate my invention. The main frame f .is arranged 'to support a stock-supportingY table 12, the-'stock being fed across a cutting agency, shown as a rotary cutterhead 13.

l-t represents ya usual side guide, which 'is adjustable crosswise of the machine,

lengthwise of the feed-rolls, as by means of a T-bolt 15 yadjustable in a cross T-slot 16 in the table, a nut 17 clamping the `side guide in adjusted positions, the side guide extending lengthwise of the machine.

, I have illustrated my `invention as applied to a feeding device having a pair of Vfront feed-rolls and a pair of rear feedrolls,V although it is obvious that, in employing portionsy of my invention, one pair of feed-rolls may be employed.

l18, 19, represent-lower feed-rolls, and 20, 21 represent upper feed-rolls. The upper rfeed-rolls are respectively mounted in housings 22, 28, the housing 22 having bearings 24 pivoted on sleeves 25, 26, and the housing 23 having bearings 27` pivoted on said sleeves. The sleeves 'l are mounted inbearings 28, 29, on side slides connected by a cross-saddle 31 rigid"`therewith for forming place, as by screws 37, for ready access V*to said slides and the adjusting screws and nuts therefor.

They forming of the guideways for the upper feed-roll frame upon the outside-*faces kof the main frameV of the machine permits the sides of the main frame to be cast integralwith each other, in other words, permits an integral main frame to be formed,

by placing the parts thereof to be machinedV uponk the outside of the main frame, and the provision of the covering plates for said recess forms pockets in which the slides of the feed-roll frame are adjustable, this con- -struction removing the moving parts from danger of contact with foreign substances.

The adjustment of the feed-roll frame is accomplished by means of screw-rods 38 journaled in bearings 39 in therespective ends ofsaid feed-roll frame. A block 40 is removably mounted in bearings 41, 42, in each side of the main frame, the blocks being threaded as at 43 between said bearings for threaded connection with saidV respective screw-rods, forming removable nutblocks, readily removable when said threads.

are worn. `Each of these screw-rods has on it a worm-wheel 44 meshed by worms 45 on a Vcross-shaft 46 journaled in bearings 47 on the feed-roll frame and having a handwheel 48 thereon for turning the same.

The screwsrods are received in vertical recesses 49 in the side-slides of the feed-roll frame, the screw-rod, nut-lock and guideways at each side of said feed-roll frame being located in coincident vertical planesy projected lengthwise of the machine, providing ease of adjustment. o

At each end of each roll housing, there is a stop 51 which engages with a lug 52 Von the feed-roll frame for Alimiting the downward movement of the upper feed-roll with relation to the plane of the stock-supporting table, the adjustment of the feed-roll frame raising or lowering the upper feed-rolls for different thicknessesof lumber to be planed,

ythe feed-rolls exerting pressure upon the stock and yielding up and down to inequalities of the stock by having the feed-roll housings swing about their pivots.

In order to adjust the respective ends of the upper feed-rolls with relation to each other on said housings, and to adjust the relative elevations of said respective upper feed-rolls, I mount each end of the shaft 53 ofeach of said feed-rolls in a. bearing 54 slidable in a guideway 55 in the swinging end of said housing. For limiting Htheupward movement of theY bearing va hollow bolt 56 is provided, which is threaded in a threaded hole 57-in the housing and arranged to impinge said bearing. A bolt 58 is received through the bore 59 of the hollow bolt and has threaded connection in the threaded socket'60'in said bearing, the head 6l of said bolt being received above and supported by the hollow bolt, the head limiting the downward movement of the bearing in adjusting said bearing. The hollowl bolt forms the positioning means for elevation of the bearing and the inn-er bolt forms the ,means for clampingthe bearing upwardly against saidpositioning means, the bearing being suspended from said Vinner bolt. By these means each end of each of the upper feed-roll shafts is adjusted, whereby the contact line of the periphery of each of said upper feed-rolls'is adjusted with relation to the level of the stock being fed, so that upon unequal wear of the peripheral surface of either of the rolls, the feeding or contact line thereof may be leveled with relation to the other roll, or either of said feed-rolls boldily raised or lowered with relation to the ot 1er. Y

Ihave shown means for driving thekupper as well as the lower feed-rolls forvfeedl ing the stock either forwardly or back. Mv

improved feeding mechanism is especially applicable to planing, planing and matching, and flooring machines, in which `it 1s desired to maintain high rates of feed. y In vmachines of this character, it has been found desirable at'times to remove a board which has been partly fed into the machine. I accomplish this b v novel means for reversing the feed.

65 represents the main drive-shaft' journaled in bearings 66, the inner ones of which are located on a bracket 67 secured to the main frame. The shaft 65 has pulleys 68, 69, 70, received thereabout. The pulley 68 is tight on said shaft, the pulley 69 is loose thereabout', and the pulley 70 is on a sleeve 71 loose about said shaft.

72 is a reversing shaft journaled in bearings 73 on said bracket. A gear-74 isv fast on said reversing shaft and meshes with a gear 75 fast with said sleeve-pulley 70.

76 is a cross-shaft journaled in bearings 77 in the main frame. It has a gear 78 fast thereon. Y

79 is a gear fast on the shaft'. y

8O is a gear on the reversing shaft.

The gears 7 9 and 80 are in mesh with the gear 7 8.

A belt 81 is arranged to pass about the pulleys 68, 69, 70, and arranged to coperate with any of said pulleys, being shiftable latarm 83 which `may also have a `tightener pulley 84 thereon in line `with saidbeltshifter, so thatsaid ybelt-,shifter andtightener pulley may simultaneously acton said belt. i The arm is pivoted by a bearing 85 about a shifter-rod 86 operatedby a handle agencyiorcutting agencies, by a suitable belt 89. lVhen the belt 81 passes aboutthe pulleyl 68, a direct `feed is imparted to the feedrollsby rotating the shaft 76 in 'the .direction of: the arrow a, the transmission of sald `shattbeing `through the shaft `65, the` gear 79 and thegear 7 8, the gears 7 5, 7 el and 80 rotating reversely in idle relation. yWhen in adjusted positions. i 102 into the lower kend of `said stirrup, and

the belt passes about the loose pulley l69, the

feed-rolls are at restiY When ythe belt is caused to pass about the sleeve-pulley 70, rotation is imparted to the shaftf 76 in a direction opposite to the direction ofthe arrow a through the gears 7 5 74C, 8O and 7 8thereby rotating the feed-rolls` in reverse directions for` reversely feeding the stock and drawing the same backwardlv out of the machine. The gear 79, main drive-shaftY and` the pulley 68 inthe meantime rotate infreverse directions inv idle relation, except when the pulley 88 is employed, when the shaft 65 acts as a transmitting shaft. f

My improved construction is such that the 'forward on reverse feeds for the feed-rolls are imparted by a straight belt, and thelchanges l in feeding relations are obtained by asingle belt, which is preferably a straight belt, received about said pulleys andfshiftablev from one pulley to another, thereby economizing in power.` Each of the lower feed-rolls has a shaft -91 journaled yat each end. of the feed-roll in a kbearing 92, slidabley up and down in a guideway 93 in the main frame.

94 is a stirrup from which the bearingis hung, as bya boltl 95,1 rotatable in a'bearing 96 in ther stirrup, and threaded into a threaded socket97 inthe upper part of said i bearing, a set-screw 98 clamping said bolt 101 is an adjusting screw, threaded at journaled in a bearing 103 in the main frame. and held against downward movement by a collar '104.

105 is a bevel-gear fast to the lower end of the adjusting screw. Cross-shafts 106 are `iourna'led inbearings 107 of the main frame. One of these cross-shaftshas `means `thereon for turning the same, as the squared end 108 arranged to receive an adiusting crank. Turning ,of the stirrup is limited by contactfwith the wall 109 ofthe guidey112 is a connecting shaft journaled in bearings 113 of the main frame, and having bevel-gears 114 thereon, these lastnamed bevel-gears meshing with the bevelf gears 105 Lat one side of the main frame.

The turning of the turning means ad justs all of the stirrups simultaneously for adjusting the lower feed-rolls simultaneyously up or down.- The adjustment of the respective roll-shaft bearings with relation lto saidy sti-rrups permits independent adjustmentlof each end of each'of the lower feed-rollsffor alining'the same with relationfto each other, and causing selective projection of the contactline of the periphery of eachk of the lower feed-rolls above the plane of the table, or for alining said contact-lines ofthe 'lower rolls with relation lbut rotates inthe same direction as ysaid shaft, preferablyl at the same speed. The gear 128 ymeshes with the gear 125 and forms one of the transmitting gears for the transmitting train of gearing fordriving the upper feed-rolls. Mounting said gear 128 about said feed-roll shaftrv permits economy in the size of gears and provides a compactr and substantial construction, and avoids thenecessity" of employing ai train of gearing off-set with'relation to said-rollshaft.

129 is a gear mounted `on a stud '130,'the gear v129 meshing with the gear 128 and with'a gear 131 fast on a cross-shaft 123 Iiournaled in the sleeves 25, 26, mounted inr the upper feed-roll frame.

Novel vgear covering and link mechanism is provided for the transmitting gearing between the cross-shaft 76 and the cross-shaft 123. Thus the gear-cover 33 'comprises an inner wall 135, an outer wall'136, and a connecting flange 137 between said walls, the connecting flange having 'an interruption 138 therein. vThis gear-cover has a bearing 139 about the cross-shaft 123 and bearings 140, 141,. in which'thefrespective ends of ther stud '130 arejournaled. A connecting rib 142 integral with said gear-cover connects the bearings 139,144.0,.and a strengthening yoke 143 integral ywith said gearcover connects the bearings 140, 141. The

outer wallfof the gear-cover is shown removable an'd is secured to the fiange by screws A'portion of the saidyoke is formed on' said outer wall and a portion on the inner part of the gear-cover, the yoke portions being rigidly connected by similar screws 144. A gear-cover 147 is provided which comprises an inner wall 148, an outer wall' 149, and a connecting flange v150 between said walls, said flange having an interruption 151 therein which mates with the interruption 138. Cheeks 153 extend from theiange 150 so that the flanges at the respective ends of said interruptions may overlap eachother irrespective of the f swinging relations of said gear-covers. There is further an arc-joint 152 between said gear-covers at said interruptions so as to avoid any detrimental space between said .a portion of said linkbeing formed as a rib Von the wall of said gear-cover and a portion thereof protruding beyond said gearcover and received within the gear-cover 147. The inner wall of the gear-cover 147 is provided with an elongated opening 160 received about the bearing 77 of the cross- Vsha-ft 76 to permit oscillation of said gearcoverl with relation to said bearing. The outer wall of the gear-cover 147 is preferably removable and is secured to the flange of said gear-cover by Vmeans of screws 161.

The lower gear-cover is pivoted about the laxis of rotation of the lower feed-roll 19 and the upper gear-cover and link mechanism is'pivoted about the axis of rotation of the cross-shaft 123. The stud 130 between the said gear-covers follows the movements of said gear-covers for maintaining proper meshing of the gear 129 with the gears 128 and 131, the swinging end of the lower gear- `cover accommodating itself to the movements of adjustment of said gear-covers and having free oscillation about the gears covered thereby. The construction of the mechanism insures complete covering for said gears throughout the range of adjustment of the feed-rolls and forms substantial link mechanism between the` gears.

Gears 165, 166,'are fast on the cross-shaft 123. A gear 167 is fast on the shaft of the upper feed-roll 20` and meshes with the gear 165 and a gear 168 is fast on the shaft of lthe upper feed-roll 21 and-meshes with the gear 166, the said gears on said shafts of said respective feed-rolls being preferably at opposite ends of said feed-rolls.

Novel means are also provided for apply ing pressure to the yielding upper feedroll housings. Each of the upperfeed-roll housings is'pressed downwardly by a coilspring 171, shown as a helical spring, the

said springs being in laterally off-set relaard, a vrnut 178 being vreceived about said threaded end. The lower end of the rodis provided with trunnions 179 received in a trunnion-socketlSl. The springk is diagonally positioned with relation to the housing and acts directly upon a part of thehousing within the arc of` swing of the axis of rotation of the feed-rolltherein,the said arc being indicatedby the broken 'line 182.- It is of course understood that one or more of these yielding mechanisms may beemployed. I have shown two lof these springs and rods, one for each of the roll-housings, the same being located in laterally off-set relation, theirw upper ends crossing each other, preferably outside said arc 182. The innerfends of said.y springs and rods are preferably-within said arc land their outer ends outside said arc. Y

The yielding pressure means shown and described provides compactnessy of structure, permits the feed-rolls tov be placed closely adjacent to eachl other, and equaliz'es the pressure of they rolls upon the stock throughout a wide range of yield of said rolls. The removable half of the lbearings 77 are held in place by bolts 183V threaded into the cross-grit 184 of the main frame. Y
