SPECIFICATION forming part of Letters Patent N 0. 576,321, dated February 2, 1897; Application filed April 22, 1898. Serial No. 471,522. (No model.)
To all whom it may concern.- of Fig. 5, looking in the direction indicated Be it known that 1, ROBERT MORGENEIER, by arrow.

The tables 15 16 are arranged at (lif applying to corresponding parts in all the ferent altitudes, as shown in Figs. 2, 3, and 4. drawings. On the table 15, movable in transverse ways 5 Figure 1 is a plan View of the machine 0 c c c, is a skeleton frame 19, composed of downward from line a a, with the exception the pieces 0 and the pieces cl d. The frame of one of the spindles,which, although shown, 19 has formed on its lower side racks e e, is above such line. Fig. 2 is a front end eleinto which mesh spur-pinions f f the pinions vation. Fig. 3 isaright side elevation. Fig. f f being rigidly mounted on a shaft 20. I00 50 4 is a left side elevation. Fig. 5 is adetail The shaft 20 is revoluble in boxes formed on of a pawl-operatin g device. Fig. 6 is a view the sides of tables, as shown. The ends of shaft are squared, so that a socketwrench may beplaced thereon. Vith such wrench the shaft 20 and its spur-pinions f f meshing in the racks e e,n1ay be turned, whereby the frame 19 is moved transversely on the table 15. The longitudinal pieces d d of skeleton frame 19 form downwardly-beveled ways. (See Fig. 2.) l pon these is firmly'mounted a head-stock 21. In theheadstock 21 is mounted a shaft 22, upon which is keyed a worm-wheel 23 and a face-plate 24. A tail-stock 25, carrying a pivot-center, is also mounted on the ways (1 d, so that it may slide or be held at any point thereon by means of a clamping-bolt. From a double box 26, secured on the lower front of the head-stock 21, a grooved shaft 27 extends horizontally and transversely of the machine to a similar box 26, mounted on the top of the head-stock 21 on the table 10. Between the boxes 26 is held a worm 2S and between the boxes 26 a worm 28 of same pitch as 28. The shaft 27 passes through these worms, which each have a stud engaging in the groove of shaft 27. Thus arranged the worms may be caused to slide over the shaft and yet be turned by the same.
The worm 2S meshes with the worm 23. Therefore if the worm 28 be rotated wheel 23, shaft 22, and face-plate 24 will also revolve. Shaft 27 is connected with the mechanism on table 10. (See Figs. 1 and 2.) Table 16 and all of the parts thereon are identical with those of table 15, just described. The adjustments and motions are also identical and made correspondingly by means of shaft 27. Besides being held in boxes 26 and 26 the shaft 27 is also held in a box 29, Fig. 2, formed on the table 15. (See Fig. 2.) Collars 3O 31, pinned on the shaft on each side of the box 20, prevent it from sliding lengthwise. On shaft 27 is rigidly mounted a ratchet-wheel 32 and a swinging arm 33, carrying a pawl 34, which pawl engages the teeth of the ratchet wheel 32. By means of a wrist-pin 35 in the swinging arm a connecting-rod 36 is fastened thereto. The rod 36 at its lower end is held by a pin 37 to a swinging arm 38, mounted on a shaft 39, which shaft 39 is held in a sleeve 40, formed on the front end of the main frame A. (See Figs. 2, 3, and 4.) A powerful spiral spring 41 is fixed with its one end into the sleeve 40, surrounds the sleeve, and has its other end fixed into the lower swinging arm 38. (See Figs. 2 and 6.) Theresilience of the spring 41 is such that it will hold the arm 38 extended horizontally.
Upon the upper and under sides of the arm and at opposite sides from the center of shaft 39, upon which the arm is loosely mounted, are formed the two lugs 42 42. (See Figs. 4 and 5.) The bar 10 passes vertically and almost in contact with one side of the arm 38. Upon that side of the bar 10 adjacent to the arm 38 are pivoted canting-lugs 43 43, held by springs 44 44 in position against limitblocks 45 45.
From the above-described construction it will be seen that if the main shaft 1 is rotated at a speed of five hundred and twelve revolutions per minute the four-inch spur-gear 3 thereon will rotate the sixteen-inch spurgear 4, with which it meshes, one hundred and twenty-eight times. The four-inch spur-gear 6, mounted, with spur-gear 4, on the shaft 5, will rotate at the same speed, i. 6., one hundred and twenty-eight times per minute. The spur-gear 6 meshes with the sixteen-inch spurgear 7, mounted on shaft 8, rotating said gear and the shaft upon which it is mounted thirtytwo times per minute. The heart-shaped cam 9 on said shaft 8 will revolve the same number of times and move the tables upon which it acts, through the medium of the wedgepointed lugs 1.1 and 12, forward thirty-tw0 times and backward thirty-two times, each time to a distance of about one and one-half inches, or a total distance of ninety-six inches per minute approximately. hen the reciprocating motion due to the cam 9 sets in, the upper pivoted canting-lug 43 on bar 10 will move against the upper arm-lug 42, depressing it and the arm upon which it is formed, such downward movement also carrying downward the connecting-rod 36, the upper swinging arm 33, the pawl 34, and these all against the stiff spiral spring 41, which holds the arm 38 normally extended. lVhen the bar 10 of the sliding tables has advanced one and on e-half inches, it will have depressed the arm 38 to its lowest point, as shown in dotted lines in Fig. 5, and after an additional one-sixteenth of an inch,- of travel, whereby the distance of the reciprocating motion is completed, the lugs will have cleared each other, whereupon the spring 41 will throw the arm 38'into its first position. This upward motion of pawl 33, which is connected and mounted as heretofore described, in the manner to turn the shaft 27 and the worms 28 28, which, meshing with the worm-wheel in the head-stocks 21 21, cause these and the shafts and face-plates of which they form a part to rotate. The distance of the rotation can be controlled by a proper adjustment of the pins holding the rod 36 in connection with the arms 33 38. Immediatelya reciprocation of the tables and a rotative motion of the plates, &c., have been effected the heartcam 9 changes the motion of the tables in the opposite direction, whereby the lower lugs 42 43 become operative. The arms 34 38 are depressed, the pawl 33 passes over, then engages on the ratchet-wheel 32, whereupon simultaneous with the ending of the reciprocation the face-plates, 850., will be again rotated. Thus it will be seen that through the medium of the cam 9 the tables 15 16 and devices thereon are continually reciprocated a distance of one and one-half inches at a speed of ninety-six lineal inches per minute, and that the revolving holders, consisting of the face-plates 24, partially rotate a predetermined distance at the termination of each one of the reciprocations named, the purpose of which will be hereinafter described.
Upon the upper longitudinal stringer 46 of the auxiliary frame B, I mount in boxes a horizontal row of hollow rollers 47, and over these in separate bracket-sleeves inclosed in a housing 48 (see Fig. 4) I place an equal number of pressure-rollers 49. Between the rolls 47 and pressure-rollers 49 a driving-belt 50, which runs over the two pulleys 51 and 52, is mounted. The pulley 51 is mounted on a shaft 53, held in boxes 54. Upon the shaft 53 is also mounted a miter-wheel 55, meshing with the miter-wheel 56, mounted 011 a vertical shaft 57, which shaft is held in the boxes 58 59, formed on the auxiliary frame 13. At the lower end of the vertical shaft 57 is mounted a miter-wheel 60, meshing with the miter-wheel 61, mounted on a horizontal shaft 62, held in a sleeve 63, formed 011 the frame A. At one end of the shaft 62 is mounted a beveled pinion 64, meshing with a vertical beveled wheel 65, rigidly mounted on a shaft 66. Upon said shaft is also mounted a sprocket-wheel 67. A chain passes from the sprocket-wheel 67 to a sprocket-wheel 68, mounted on the journaled end of a horizontal traction-roller 69, said roller 69 being placed under and parallel to a similar roller 7 O. Rollers 69 70 are connected by spurgears in ounted on the shaft end of such rollers. On shaft '75 is also mounted a driving-pulley 78, from which a belt passes to a counter-shaft,
furnishing power to rotate the mechanism just described. In each one of the row of horizontal rollers 47 is a spindle 79, reciprocal therein and revoluble with the roller because of a longitudinal groove in such spindle in which rides a stud or pin 81, proj ecting from the inner wall of the roller and engaging in the slot or groove 80. The left end of the spindle is formed into a chuckhead 82, and the shank of acutting-tool 83 is mounted firmly in the chuck by a compression-collar 84.
At the rear end of the spindle 79 are rigidly fixed collars 85 85, and held between these is a double-lipped collar 87. At right angles to the lips of the collar 87 and firmly fixed therein is a rigid pin 88, and the slotted end f of a pivoted lever 89 passes on two sides of such pin, the lever 89 being pivoted at its center by means of an eyebolt 90. The eyebolt 90 can be advanced or retracted and in whatever position placed can be firmly held by means of the jam-nuts 91. 92, placed on the two sides of a lug 93, through which such eyebolt passes, the object of which will be hereinafter described.
The lower end of the lever 89 is slotted and held in the same manner as its opposite end by means of a pin 94, held in the lips of a collar 95, and the collar is held between rigid collars 101, mounted at the rear of chuck 96. A guide-finger 102 is firmly held in chuck 96 bya compression-collar 103. The rear end of the chuck is elongated into a holt er of the tail-stock 25.
low spindle or tube 104, which passes between the two traction-rollers 69 70, and back of such rollers passes through a bore-hole in a lug K. \Vithin the tube 104 is projected a rod 105, which rod is held in such position. in a lug 107, formed on the main frame A. Upon this rod and passing into the tube 104 is a spiral spring 106, held firmly under pressure.
From theabove description it is manifest that if the belt on the pulley 7 8 revolved such pulley and its adjacent pulley 52 (each eighteen inches in diameter) at the speed of four hundred and sixteen revolutions per minute then the belt 50, passing from the pulley 52 to 51, will speed at the rate of twenty-three thousand five hundred and sixty-two inches per minute, and the rolls 47 (one and one-half inches in diameter) and the spindle 79, held within such rolls, will, because of the friction of the belt 50, due to pressure from the upper rollers 49, revolve at the rate of five thousand revolutions per minute approximately. The cutter-spindle 79 is connected by means of its lever 89 in the manner that when the guide-finger 102 is held projected forward bythe spring 106 within the guidefinger tube the cutter and spindle will also be projected.
As heretofore stated, the guide-finger tube is held between the pair of corrugated traction-rollers. Now if pressure is brought to bear against the side of said finger a slight gyration or partial gyration of the finger and tube will take place and thereby establish traction contact between such particular tube and the rollers. These latter moving in the direction of the arrow, as shown in the drawings, will draw the tube and its finger backward against the pressure of the spring within the tube,and immediately when such pressure against the finger ceases the spring will again project it forward.
To reproduce a statue of about six feet in height, I proceed as follows: Having placed cutters in the chuck-heads 82 and guide-fingers in the chuck -heads 96, and having brought the ends of these in a perfect line against a straight edge by properly" turning the regulating nuts on the eyebolt, upon which each connecting-lever is pivoted, I then move the frames 19 19, carrying the head and tail stocks away from the extended guide-fingers andcutters, this by means of the racks e e and pinions f f. On the faceplate 24" I fasten the base end of the pattern and support the head end on the pivot-cen Upon the left-hand higher table 15, between the face-plate 24 and the tail-stock 25, I place in the same manner a mass of material of size sufficient to form a duplicate of the pattern employed. I now set the pin connecting the arm 33 and the rod 36 at a point whereby the pawl 34 when forced upward will cause the pattern and material to turn slightly on their axis. If the worms 28 28 and worm-wheels 23 23 are all formed so as to turn in one direction,
the image made by the machine will be an exact duplicate of the pattern. If, however, I remove the worms and Wheels on one side and put in their place a set formed to move in an opposite direction, so that the pattern will rotate to the left and the material to the right, the resulting image will be a complementary duplicate of the pattern. Thus from one pattern complementary duplicates may be made. I'Iaving set the connections of arm 32-3 and rod 36 as stated, I set the machine in motion by means of the belts on driving-pulleys 2 and '78, whereupon tables 15 16 Will reciprocate the patterns and material turned slightly upon their respective axis. The cutters S3 revolve at about five thousandturns per minute and the traction-rolls surrounding the guide-finger all revolve in the direction of the arrows. The pattern and material are new advanced upon the guide-fingers and cutters until each of the latter has cut into the material to the depth permitted of by this particular guide-finger. During this cutting the tables are moving longitudinally and the guide-finger points are pressing against the surface of the pattern. If such surface is undulating, the pattern will push the fingers backward and allow the springs in the finger-tubes to force them forward when the undulation deepens. If, however, an abrupt angle of the pattern suddenly presses against the side of a guide-finger, its slight gyrability will at once cause its tube to press against the traction-rollers, and these will retract the finger to the height of the particular part of the pattern at that moment moving or pressing against the finger. If a parallel surface of the pattern passes before one or any of the fingers, these will be steadily projected against such plane. I
When the tables holding the pattern and material have completed the distance of their first reciprocating travel, the profile of the pattern in horizontal position before the row of guide-fingers will have been cut into the material placed before the cutters. Immediatel y thereupon both pattern and material rotate slightly, whereby the'pattern presents a new profile for the guide-fingers to act upon, and new material contiguous with the first profile cut is presented, upon Which the cutters may operate. lVith the return reciprocationthe second profile is reproduced and thus the work of the machine proceeds, the
pattern and material reciprocating and revolving step by step before the guide-fingers and cutters. The profiles cut by the row of cutters always being wider than the side mo tion of the material and pattern, all the cuts following the initial one are repeatedly overlapped, whereby a complete interblending of the cutting eifect and consequent smooth and perfect duplication is secured. After placing the cutters and guide-fingers properly and bringing the material and pattern in proper position the operation is entirely automatic on the part of the machine, and one operator may attend to a number of machines.
I claim 1. I11 a statuary-duplicating machine, the combination with a series of revoluble and reciprocal cutters, of a series of reciprocal guide-fingers connected therewith and adapt ed to control the movements thereof, and rotatable pattern and material holders, sliding tables Whereon said holders are mounted, gearing for causing the reciprocation of said tables, said last mentioned gearing being adapted to actuate the rotating mechanism, substantially as described.
2. In a statuary-duplicating machine, the combination with rotatable pattern and material holders, sliding tables upon which said material and pattern holders are mounted re spectively, said tables being rigidly connected, a driving-shaft having a cam for reciprocatin g the sliding tables, a worm-gear for rotating the pattern and material holders and an intermittently acting pawl and ratchet mechanism whereby upon the completion of a reciprocal movement of the tables a partial rotative movement of the pattern and material holders is effected, substantially as described.
3. In a statu{try-duplicating machine, the combination with a reciprocal and revoluble cutter, of a reciprocal guide-finger and alever pivotally connecting said guide-finger and cutter, a rod whereon said lever is pivoted, said rod being adjustable through fixed bearings whereby the cutter and guide-finger may be advanced or retracted, substantially as described.
