Application filed November 8, 1886. Serial No. 218,344.
To all whom, it may concern.:
Be it known that 1, C. ELMER BIoKEoRD, of Vinchendon, in the county of W'orcester and State of Massachusetts, have invented certain new and useful Improvements in Automatic food Drilling and Turning Machines, of which the following, taken in connection with the accompanying drawings, is a specification.
The objectof my invention is to produce an automatic wood drilling and turning machine that will automatically drill and turn pailhandles, spools, and otherlike articles of wood or similar material.
It consists in the construction and arrangement of mechanisms adapted to automatically take from the hopper a rectangular block of wood sawed to dimension, drill a hole through it lengthwise, then carry it to the turning devices, where it will be roughed' off to its approximate diametrical shape, afterward being reduced to its absolute shape by a gaged cutter and delivered from the machine in a iinished, drilled, and turned state.
Figures 1 and 2 represent, respectively, in front elevation and plan, my automatic wood drilling and turning lathe, and Fig. 3 is a vertical cross-section of same on line 25 25 of Fig. l, looking toward left-hand end of lathe. Fig. 4 is a partial section of drill chuck, showing method of adjusting and holding drill; and Fig. 5 is a vertical crosssection of same on line 26 26. Fig. Gis a front elevation of screwdrill stop.

Fig. S represents details of construction ot' spur-chuck, driving-spia dle, and step; and Fig. 9 is a vertical crossseetion of step of same on line 27 27. Fig. 10 is a rear elevation of spring used in connection with hopper-feeding mechanism, and Fig. 11 is a vertical crosssection of same on line 2S 28. Figs. 12, 13, 14 are detailed views of gougedriving mechanism, respectively in front elevation, side elevation asv viewed from lefthand side of lathe, and side elevation as viewed from right-hand side of lathe. Figs. 15,16,17, and 1S represent, respectively, a wood pailhandle in its four stages of production-namely, first, cut to dimension in the usual manner as it is placed in hopper; sccond, after being drilled; third, after being roughed off; fourth, after being gage-cutter finished and delivered from the lathe asa pailhandle in a drilled and turned state, after (No model.)
which it may be polished in the usual manner. Fig. 19 is a vertical longitudinal section of drill-spindlethrust bearing on line 29 of Fig. 2, with end of drill-spindle in side elevation, showing arrangement of thrust-bearing; and Fig. 20 is a full vertical cross-section of Fig. 19 through keyway. Figs. 2l, 22, and 23 represent, respectively,gage-cutter in plane, front, and side elevation. Fig. 24 represents gagecutter cam-wheel in side elevation as viewed from leftlhand side of lathe, and Fig. 25 represents gagecutter cam-wheel in front elevation. Fig. 26 is a detail view of the chuck and cam-shafts with parts thereon. Fig. 27 is a detached rear view of the feeding mechanism, the chuck, and the drill-shafts. Fig. 28 is a detached rear view of cutter-carriage and a portion of the operating mechanism therefor. Fig. 29 is a perspective view ofthe feeding mechanism, the chuck shafts, and the drillshafts. Fig. 30 is a bottom plan view of the chuck and part of the camshaft on a line above the driving-pulleys and shaft.
The main driving-shaft 30 is mounted in the frame 31 in bearings 32 and 33, and is held in its position lengthwise by means of collars 34 and 35, which are secured to the shaft 30, which is driven by means of main pulley 36, which is fastened to the shaft and is driven by belt. (Not shown.) The shaft 30 has fastened to it the double-crown driving-pullcys 37 and 3S.
The left-hand drill-spindle, 39, mounted in bearings 40 and 41, which are bolted to frame, and having straight pulley 42 secured to spindle, is rotated by means of belt 43, ruiming from the crown 44 ot' double-crown drivingpulley 37 over straight pulley 42.
The right-hand drill-spindle, 45, mounted in bearings 46 and 47, which are bolted to frame, and having straight pulley 4S secured to spin'- dle, is rotated by means of belt 49, running from crown 50 of double-crown drivingpulley 38 over straight pulley 4S.
The lcl`t-hand spur-chuck spindle, 51, mounted in bearings 52 and 53, which are bolted to frame, and having straight balance-pulley 54 secured to spindle, is rotated by means of belt 55, running from crown 56 of double-crown driving-pulley 37 over straight balance-pnl` ley 54.
r)She right -hand spurchuck spindle, 57, mounted in bearings 53 and 59, which are bolted to frame, and having straight balanee- ICO is rotated by means of belt 214, running from main driving-shaft 30 over clutch-pulley 66. The clutch-lever 70, (see Fig. 3,) having its fulcrum in bearing 71, which is fastened to frame, is provided at one end with the handle 72 and at the other end with clutch mechanism of the common style, so that when in use the pulley 66 is driven by belt 214, and by` means of operating the clutch mechanism in the usual manner the shaft 63, to which the gear 67 is fastened, will be driven by pulley 66.
To the feed-shaft 73, mounted in bearings 74 and 75, are fastened the drill-feed camwheels 76 and 77, spur-chuckfeed cam-wheels 78 and 79, feed shaft gear 80, gage-cutterfeed cam-wheel 81, gouge-cutter-feed camwheel 141, collars 82 and 84, and hopper-feed cam-wheel 83. The drill-feed cam-wheels 76 and 77 serve as collars to keep feedshaft 73 in itslongitudinal position.
gear 80 is arranged to mesh with and to be driven by gear 67.
rlheV left-hand drill-spindle, 39, is provided with thrust-bearing 85, which is shown in detail by Figs. 19 and 20. The thrust-bearing, in which the spindle is free to rotate, is provided with key 86, which holds the spindle in its position by means of the engagement of the key with circulargroove 87. Both drill-spindles and both spur-chuck spindles are provided with thrust-bearings similarin construction' to thrust-bearing described, and any wellknown style of thrust-bearing may be used, except that they must operate substantially as hereinafter stated, and all said spindlesare reciprocated in a similar manner by means of devices hereinafter described.
Thrust-bearing 85 is provided with projection 88, which is provided with recess 89, into which is fitted one end of the lever 90, which is pivoted by means of fnlcrum-pin 91 and support 92,which is secured to frame, the other end of the lever being provided with pin 93 and wheel 94, the arrangement being such, as shown, that the revolving of the cam-wheel 7 6 will cause the necessary reciprocating movement of the drill-spindle 39.
The reciprocating movement of the righthand drill-spindle, 45, is obtained in asimilar manner, as above stated, by means of thrustbearing 95, projection 96, provided with recess 97, lever 98, fulcrum-pin 99, and support 100,pin 101 and wheel 102, and cam-wheel 77.
The forward movement of the left-hand spur- Ihe feed-shaft.
chuck spindle, 51, 'is obtained by means of thrust-bearing 103, projection 104, recess 105, lever 106, fulerum-pin 107 and support 108, pin 109 and wheel 110, and cam-wheel 78, and said spindle is returned by spring 122.
The forward movement of the right-hand spur-chuck spindle, 57, is obtained by means of thrust-bearing 111, projection 112, recess 113, lever 114, fulcrum-pin 115, support 116, pin 117, and wheel 118, and carn-wheel 79,and said spindle is returned by spring 120. The
forward motion of right-hand spur-chuck spindle is carried by means of spring 119,fastened to lever 114, as shown in detail `in Fig. 8, for reasons hereinafter given. The lever 114 is also provided with spring 120, which is constructed as follows: The spring being pivoted on pin 115, one end ot' spring is fastened to support 116, the other end pressing against pin 121 in lever 114 with a force requisite to keep wheel 118 always in contact with and subject to the cam action of cam-wheel 79. In a similar manner lever 106 is provided with spring 122, which is constructed as follows: The spring being pivoted on pin 107, one end ofthe spring is fastened to support 108, the other end pressing against pin 123 in lever 114 with a force requisite to keep Wheel 110 always in contact with and subject to the action of cam-wheel 78.
The gouge-cutter-feed mechanism is constructed as follows: The gouge 124, of the usual construction, is fastened to round rod 125, which travels horizontally in bearings 12,6 and 127, which are secured, respectively, to bearing-supports 41 and 46. The gouge-gage 128, against which the gouge rests, is adjustable by means of slots, through which screws 129 and 130 pass and fasten .gage to `frame. The gouge-gage 128 has a section, as shown in Fig. 3, and being horizontally located and being also adjustable by means of slots through which set- screws 129 and 130 pass, as pre vionsl y described, it serves as a gage and backrest for the gouge,which can beset, as desired, at any angle, as its supporting-rod 125 is capable of turning in its bearings 126 and 127. To the gouge is swivelly fitted the pin and block 131, so made that the rotative setting of i the gouge by means of its gage 128 will not interfere with its reciprocating action. Side lever 132, which is fastened to shaft 133, mounted in bearing 58, fastened to frame, is connected to block 131 by means of pin 135, connecting-rod 136, and pin 137. It will thus be seen that when the gouge is turned in setting, the swivel-block 131, to which rod 136 is pivoted, will turn in its socket, and thus permit the longitudinal movement of the gouge. The lower end of shaft 133 has fastened to it side lever 138,which is pivoted to forked camrod 139 by means of pin 140. The gougecuty ter-feed cam-wheel 141 and forked cam-rod 139 are held laterally in position by means of collars 82 and 84. The eam-wheel 141 is provided with the pawls 142 and 143. Pawl142,
pivoted by means of pivot 144, is provided l'OO IIO
'with lip 145, which is arranged to engage pin 146, which is fastened to collar 82, the pawl being held against collar by means of spring 147, fastened to staple 148. Fawl 143, pivoted by means of pivot 149, is provided with lip 150, which is also arranged to engage pin 146, the pawl being held against collar by means of spring 151, fastened to staple 152. The forked cam-rod 139, guided between camwheel 141 and collar 84 and by feed-shaft 73, has a reciprocating movement in use by realson of engagement of pin 153, which is operated by cam-wheel 141. The cam-wheel 141 being driven by the engagement of pin 146 of collar 82 with lip of pawl, the ovcrhanging end of each pawl is arranged to strike piece 154, fastened to frame, in such a manner as to throw the pawl out of engagement with pin 146,there by permitting cam-wheel 141 to remain at rest during about one-half of a revolution of feedshaft 73, or until pin 146 engages with the lip of pawl not in contact with piece 154. The result of the gouge-cutter-feed mechanism operating as described will be the intermittent reciprocating motion of the gouge.
The hopper 155 is provided with two ways, 156 and 157, one at each side, in which are stacked blocks to be operated upon. The feedcarriage 158 is guided and travels in ways 159 by means of the following mechanisms, (sec Fig. 3:) adjustable bolt and nuts 160, pin 161, link 162, pin 163, forked rod 164, pivot-pin 165, fastened to end of bent lever 166, which is pivoted by pin 250, (shown in Fig. 26,) fastened opposite pin 167 to bearing-support 65, and is provided with pin 168, which is operated by cam-wheel 83, slotted bracket 169, provided with pin 167, which tits fork of rod 164, is adjustable by means of slot 170, and screw 171, which passes through slot and so fastens slotted bracket 169 to piece 172, which is fastened to bearing-support 65.
The position of the carriage is regulated by the use of bolt and nuts 160, by unscrewing one nut and screwing up the other, as will be obvious. The distance of travel of the earriage is regulated as follows: The arm 164 is pivoted in a slot on pin 167 and is operated by pin 165 in the lever-arm 166. Asthe pivotpin 167 is supported by the bracket 169, which is adjustable on screw 171, said pin may be adjusted in the slot of the rod 164, and as it is moved in relation to the pin 165 the short arrn of the rod 164 is shortened or lengthened and the throw of its long arm regulated at will. Cam-wheel 83 is adjustable by means of slots 173 and 174, struck on a curve concentric with its center, and screws 175 and 176, which fasten cani-wheel to feed-shaft gear 80.
The plunger 158 comprises a frame-work provided at the top with the upper face, 177, formed integrally with and operating at the upper part of said plunger, and which in use will move laterally and push the lowermost block from the bottom of the pile in the hopper backward into position to be drilled, where it is held by means of spring 178, fastened to the lower end of the hopper and projecting rearwardly therefrom, as shown in detail by Figs. 10 and 11. The block is meanwhile held and guided by springs 179 and 180, fastened to hopper, which projects rearwardly therefrom, and are arranged to prevent the block while being drilled from being forced back toward the hopper by bearing upon each end thereof. The frame 181, in which the plunger 158 moves, is provided with a vertical chute, 182, through which the block after being drilled falls, being pushed onward after the drilling is cornpleted by the action of said upper face, 177, when it drops down the chute 182 onto ngers 184 and 185, carried by the lower face, 183, of the plunger. rEhe block is next carried forward to position :l'or spur-chucks by means of the forward movement of the lower face, 183, of the plunger, which lower face is located opposite the space between the chuck-spindles 51 57, where said block is held in position vertically by fingers 184 and 185, one on each side of and arried by face 183, and laterally by springs 186 and 187, 'fastened to the frame. lt will be understood that the upper face, 177, and lower face, 183, are each fastened to said plunger and move simultaneously therewith and with each other. )Vhile the upper face, 177, is forcing one drilled block backward to the chute 182 of the frame the lower face, 183, is simultaneously carrying the block next in advance thereof forward into position for the spllr-ehucks.
Thegage-cutter215,0fthe usual style, (shown in detail by Figs. 2l, 22, and 23,) is fastened in the usual manner and in its correct position to gage cutter carriage 188, which is operated in horizontal grooved ways 189 and 190, provided, respectively, in bearing-supports and 58. The movement of the eutter-earriage is stopped by adjustable screwstop 191, which is secu red to carriage on one side by means of piece 192 and screw 193 and strikes against bearing-support 53, thereby positively limiting the movement of the cutter-carriage.
Gage-cutter cam-wheel 8l, fastened to shaft 73 or cast with gear 80, (shown in detail in Figs. 24 and 25,) operates the gage-cutter earriage as follows: The shaft 194, mounted in bearing 195, which is fastened to frame, has to one end adjustably fastened by means of set-screw 196 the level-197, which is provided with pin 198, which is operated by its engagement with cam-wheel 8l. To the other end of the shaft is secured the lever 199, provided with spring 200, both lever and spring beingr fitted, as shown, in recess 212 in carriage, and the lever operating against a removable plate, 213, secured by a screw to the gage cutter carriage By means of the mechanisms described the cam-'wheel 81 in operation gives to the gagecutter carriage 188 a reciprocating motion.
rJhe spring 200 is used to give yielding mo- TOS IZO
tion to gage-cutter, so as to prevent accidents to mechanism and clogging of lathe in case of excessive work being required of gage-cutter. The use'of spring 119 in thrust-bearing 111 is for a similarpurpose, viz: to prevent heating of bearings due to excessive thrust of spindle 57, due to uneven lengths of blocks required to beheld by spur-chucks. It is also used to cause the forward motion ofthe righthand spur-chuck spindle.
Each drill-spindle is constructed with a socket to receive adjustable positive stop-drill chuck 201, which is shown in detail by Figs. 4, 5, 6, and 7, and is made as follows: Shank 202 is made to fit drill-spindle socket. The drill-chuck is provided with transverse slot 208, adapted to receive key 20G. The projecting end 203 is threaded and is provided with threaded stop 204C, which is provided with slots 205, adapted to receive the key 206, which is provided with recess 207, adapted to receive drill. The chuck is provided with central bore, 209, to receive drill, and set-screw 210, to fasten drill 201 in chuck. Drill chuck for right-hand spindle, 45, is preferably provided .with a left-hand drill and rotated in the same direction as drill-chuck for left-hand spindle.
The drill-spindles may be directly provided with the adjustable stop devices instead of having them applied to drill-chuck.
The detailed operation of the different parts of my machine have been previously fully described.
r[he operation of my wood drilling and turning machine adapted to produce wood pail-handles in a finished, drilled, and turned state from rectangular blocks is as follows:
All the mechanisms previously described having been correctly adjusted, timed, and set, the machine having been put in operation, and the hopper having been supplied with blocks of a shape as represented by Fig. 15, the rst forward stroke of plunger and upper face will push the bottom block from the hopper to its position in front of drills, where it is held in position by means ofthe spring devices while the drills drill a hole through the block, as represented by Fig. 16. Thefeed of the drills is as follows: Both drills advance until they nearly meet in the center of the block, thereby leaving a small portion of the block near its center not drilled, which portion is removed by ihe right-hand drill, which has a greater travel than the left-hand drill. Motion is imparted to these drills by their respective cams, which latter are shaped and timed accordingly.
In practice it is very important that drills should have an adjustable positive stop. Otherwise, as is now the casein lathes in common use, the drill or drills are liable, after being adjusted, to slip, and many blocks are spoiled or are defective for the reason that the drills do not drill the hole entirely through the block. After the block has been drilled aud the drills have been withdrawn from block by the action of the cams 76 aud 77, the second forward movement of the plunger and upper face pushes the second block into position to be drilled, and as it is pushed forward it pushes the first block into the chute, down which it falls to the bottom thereof, where, when .the third block is pushed forward to be drilled, the first block is carried forward by the lower face, and is heldby the fingers and spring devices until it is taken by the left and right hand spur-chucks and rapidly rotated. While rotating, the gouge travels from right to left and roughs off the block, as represented by Fig. 17. When the gouge reaches its lefthand position, it remains at rest until the gagecutter advances and gives the finishing gagecut to the block, which then becomes a pailhandle in a finished, drilled, and turned state, as represented by Fig. 18. After the gagecutter has performed its work and while it is returning to its backward posit-ion, the spurchucks are withdrawn, thereby releasing the pail-handle, which is pushed from its position and falls through the frame into a proper receptable. The second block is roughed off by the gouge-cutter while traveling from left to right.
All the operations being automatically, regularly, and consecutively performed and the hopper and lathe being supplied with blocks, the number of pail-handles produced is represented by the number of forward movements of the plunger.
What I claim as new, and desire to secure by Letters Patent, is
1. The combination, with the hopper 155, having vertical ways 156 157, and springs 178, 179, and 180, projecting rearwardly from the lower end of said hopper, of the plunger 158. located below the lower end of said ways and springs, the upper face-piece, 177, and mechanism for reciprocating it beneath said hopper and springs, substantially as described.
