The work-holders and drills chine embodyinga universally-movable workare mounted above the table A, while the holder, with a pattern for automatically conmajor portion of the operating and controltrolling the positions of the work-holder, in ling mechanism is located below the level of 55 combination with a cooperating mechanism the table and is supported upon the legs B for operating upon the Work carried by the and cross-pieces O. holder.

Fig. 3 is Running longitudinally of the table is a a top plan view of a portion of the operating suitable dovetail recess a Fig. 2, in which is {00 5o mechanism with the table, work-holders, and located a bolt for adjustably securing the patterirdisks removed. Fig. etisahorizontal base E of the feed-slide e to the top of the tashafts a, journaled in the head F and carrying at top and bottom forwardly-projecting and adjustable rods a, provided at their forward ends with block-holders G G, having vertically-adjustable jaws g, adapted to be moved toward and from each other by a spindle g, Figs. 9 and 10, having right and left hand threads cut thereon and also provided near the center with an adjustable jawor guide 9 forirregular work. As thus mounted it will be noted that the work-holders may be swung horizontally with the shafts a as centers, and the length of the are described by such work-holders will be governed by the length of the rods (1, which being adjustable in the shafts 0, enables the work to be swung in accordance with its surface contour, and
it will be further observed that the head F' being journaled on the trunnionfpermits the,
said trunnion-block f. The mechanism for: directly controlling these movements of the.
movement of the work-holder toward and from the drill, is primarily operated from a driveshaft J, having fast and loose belt-pulleys 7' 7' thereon. Said shaft J is provided at one end with a wormj, which transmits motion to a transverse horizontal cam-shaft K through the medium of a worm-wheel j, Fig. 3, and the latter is adapted to support the controlling-cam for the several mechanisms. Shaft K has at an intermediate point in its length a hub K, keyed thereon, and upon this hub are journaled cams 7c is, the cam in controlling the movementof the feed-slide and Workholders toward and from the drills through the medium of an operating-lever M, roller m, bearing on the cam, and connectingrod e,
adjustably connecting the said lever M and feed-slide, while the cam 76 is adapted to cooperate with a roller 'n, (dotted lines, Fig. 1,)
mounted at an intermediate point on the lever N, journaled beneath the table A at one end and at its opposite end connected by a connecting-rod n with a bell-crank lever n, Fig. 3, journaled on a vertical post p. The bell-crank lever n is provided with doubleactiug pawls n adapted to engage a ratchet-wheel n mounted on the postp', and the latter, when rotated by the operation of the cam is, being adapted to transmit such motion through the medium of a worm p and worm-wheel 10 to a pattern-shaft P.
The lever M before referred to is adj ustably connected with the rods e by a set-nut m and it is held against the cam and the slide advanced by a spring m.
The cams k k are timed to move the shafts P only when the lever M and feed-slide are moved rearwardly, and hence inasmuch as the adjustments of the work-holders are controlled through the pattern-disks carried by the shaft P it is obvious that the drills operate upon the work only when ihe cam is is inoperative and while the work is held in its .adj usted position..
The pattern-disks are preferably secured to a pattern-carrying disk Q on the shaft P and are indicated by the letters R and S in the accompanying drawings. One of said pattern-disks is adapted to control the vertical 'adjustment'of the work-holders and the other the horizontal adjustment of the same through the medium of crank-arms s and 7', carried by the rocker-shaft L andhaving antifric- 'tion-rollers r and U2 adapted to run on the peripheries of the pattern-disks and to be moved in accordance with the predetermined irregular outlines'of the latter. Both of said movements are preferably imparted to the work-holders through the medium of a frame I), to which each of the work-holders is pivotall'y connected by ap'late-V, having a central trunnion, as shown clearlyin Figs. 2 and 8, and which frame I) is provided with a' transversely-projecting arm carrying an antifriction-roll'er c, to which the moving power is applied. For producing the horizontal move 'ment the said antifriction-roll'er c- (which, it will be noted, is a grooved roller) isembraced by horizontal rods 0 connectedt'ogether rigidly by sleeves I), mounted on the ends of parallel cranks c, formingthe upper end of vertical shafts 0 0 journaled in a slide h, carried in vertical slideways H on the main frame A. When either one of said vertical shafts 0 is oscillated, it will swingthe cranks c, and thus impart to the frame b and work-holders a hori-- zontal movement on the'shafts a as centers, the necessary transverse freedom being permitted by the arrangement of the antifrictionrollers 0 between the parallel rods 0 One of the shafts 0 extends down below the slide h and is preferably sustained at its lower end in a bearing Q). At an intermediatepoint it is provided with a relatively-long wing, preferably formed by a shaft 0 connected with the shaft 0 by arms 0 This wing or shaft 0 is embraced by a fork 0, Figs. 7 and 4, mounted on a link 0, carried'at one end by a link 0, pivotally connected with the main frame, and at the opposite end by a sleeve and crank-arm .9, connected rigidly but adjustably with the crank-arm s, journaled on the rocker-shaft. (See Figs. 4 and 6.) These two arms 8 and 8', while connected,are loose on the rocker-shaft, so as to oscillate independently thereof, and provision is made for enabling the arm .9 to be adjusted for pattern-disks of various sizes by connecting 'itso uter end with the part 8' through the medium of an arc-shaped slot and set-bolt 3 Fig. 6.
The vertical shaft-s 0 being mounted in hearings in the slide it it is only necessary to move said slide vertically in order to impart to the work-holders a vertical oscillation on the trunnion f, and this vertical movement of the slide 77, is secured by connecting with said slide through the medium of a link It a crank-arm Z on the end of the rocker-shaft L and connecting the arm 1" with the opposite end of said shaft by a key or otherwise. The arm 7", it will be remembered, is controlled in its movements by one of the pattern-disks, and thus as said disk is rotated the arm will be moved up or allowed to drop in accordance with the irregularities of said disk, and thus the work-holders will be moved correspondingly.
To insure the unitary oscillation of the shafts 0 0 they are also preferably connected by arms 0 which project at an angle from the arms of cranks c and an intermediate link a as shown clearly in Figs. 1 and 8.
In the practical operation of the machine it is desirable that pattern-disks should be provided which'will be of such diameter as to control the formation of all of the holes in one piece of work, and when all the holes have been formed a stop mechanism should be brought into action which will arrest the further operation of the machine until the movement is again inaugurated by theattendaut. This end I accomplish in the present instance by interposing between the cams it it and the hub K a suitable clutch or pin connection W which may be thrown out of action, so as to release the cams from the operation of the shaft, by means of a controllingr0dsuch, for instance, as the rod q-and this rod q I control by means of a stop projection g on the pattern-carrying disk Q. The stop projection q, coming in contact with the lower end. of the rod q, will advance the same until it is in position to release the cams, as aforesaid, by running under the pin W and lifting it out of the recess W, where it is held by the catch 7.0 until the rod q is drawn out by its spring 10 to release the pin. The end of rod Q is provided with a projection (1 having two inclined faces g (1 The face (1 passes under the end of pin W to raise it and stop the cams 70, while the face (1 when the rod is moved out by its spring, passes under the latch 10 moving it out to release the pin W By mounting the stop projection q adjustably on the disk Q it is obvious that the adjustment may be made so as to arrest the operation of the machine at any desired point in the rotation of the pattern-disk, and consequently the work may be finished when any predetermined hole has been completed. To again inaugurate the movement of the machine, itis only necessary that the disk Q should be advanced by the attendant far enough to release the throwout rod g from the action of the projection q,
and in the present machine this may be conveniently accomplished by means of a handwheel 19, mounted on the shaft 19, and which the attendant may grasp and rotate slightly to advance the pattern-shaft and patterns.
The drill-spindles before referred to may be conveniently rotated by means of a belt running over a pulleyj on the shaft J and guided by an idler a. To tighten said belt and insure a better grip on the pulleys of the drill-spindles, I prefer to mount intermediate each of said drill-spindles a tightener-pulley U, beneath which the belt will pass in running from one drill-spindle to the next and which tightener-pulleys may be adjusted by set-screws 11. as shown clearly in Fig. 2. Each drill-spindle carries a chuck t for holding the drills t and to adjust the depth of the hole or cut of the drill I prefer to mount a gage t adjustably in the head D, which gage surrounds the drill at its outer end, and thus the drill may be set or the gage set to give the required depth to the opening, inasmuch as the spring m will only advance the work until it comes into contact with the gage or gages.
Inasmuch as the formation of the patterndisks to give the desired angle and position to each of the holes being drilled might be difficult I propose in the present machine to form such pattern-disks directly in the machine itself, giving to such disks a contour formation which will be in accordance with a templet or sample work-block previously worked out by hand or otherwise produced. In order to accomplish this, suitable blank pattern-disks are substituted for the patterndisks R and S, and the cutters W are substituted for the antifriction-rollers r in the ends of the arms a" 8. These cutters are adapted to be driven by belts passing around pulleys w on the cutter-spindlew ,and thence around idlers w to pulleys W on the shaft J, all as shown clearly in Fig. 12. With such an arrangement if the previously formed templet or work-block be clamped in one of the work-holders and a blank stub or drill mounted in the corresponding drill-spindle the operator can by positioning the workholders cause the cutters to dress down the peripheries of the pattern-disks to conform to the outlines necessary to control the reproduction of other work-blocks in exact conformity to the templet or sample block. To enable the operator to control the positioning of the work-holders, I preferably connect arms 3 with the arms 0 s and extend screw shafts or links 8 upwardly from the outer ends of the arms 5 through the work-table A and apply hand wheels or nuts 8 to such links, whereby the operator can by rotating said hand Wheels or nuts force the work-holder into the proper position and simultaneously cut the peripheries of the pattern-disks, as before explained. When the machine is running automatically for the reproduction of work-blocks, the links 5 and hand-wheels frame, a work-holder head journaled in said feed-slide so as to oscillate in asingle plane, a work-holder shaft journaled in said head to oscillate in a plane at right angles -to the plane of oscillation 0f said head, Work-holders mounted on forwardly-projecting rods carried by said shaft, pattern-diskszandmechanism interposed between said Ipatter-ndisks and work-holders independent of the workholder-carrying mechanism :for positioning the same in accordance with the predeter- :minedcontour outlines of :the pattern-disks; substantially as described.
