SPECIFICATION forming part of Letters Patent No. 695,119, dated March 11, 1902.

Application filed November 13, 1899. Serial No. 736,834. (No model.)

To all whom it may concern:

Be it known that I, VERNON R YLE, a citi zen of the United States, and a resident of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Oylinder-Routing Machine, of which the following is a specification.

My invention relates to a cylinder-routing machine in which the cylinder to be operated upon and the cutting-tool are arranged the one to move bodily toward and away from the other and the cutting-tool to follow a line corresponding to an element of surface of the cylinder and a line transverse to the element of surface, the several movements of the tool and the cylinder to be routed being within convenient control of the operator.

In the accompanying drawings, Figure 1 is a view of the machine in front elevation, the position of the cylinder to be routed being indicated by a broken line. Fig. 2 is an end view of the same. Fig. 3 is a top plan view. Fig. 4 is a view in detail showing the means for chucking the cylinder. Fig. 5 is an enlarged view in detail of the means for adjust ing the cylinder-operating mechanism in different positions relative to the operator. Fig. 6 is a vertical section of the same along the line 6 6 of Fig. 5. Fig. 7 is a top plan view of the parts represented in Fig. 6. Fig. 8 is an enlarged View in detail, showing the drum for applying tension to the wire which transmits a rotary motion to the cylinder. Fig. 9 is a top plan view of the drum, and Fig. 10 is a plan view of the lower section of the drum.

The machine illustrated in the accompanying drawings to show a practical embodiment of my invention provides for mounting cylinders of varyi ug diameters and varyinglengths, so that their upper element of surface will 00- cupy a predetermined position in space and so arranging the cutting-tool that it may be moved bodily toward and away from the cylinder at any point along its upper element of surface, while the cylinder itself may be rotated back and forth at will beneath the cut ter to permit the latter to operate upon the cylinderat any point of the periphery desired.

The column which forms the main support for the operating parts is denoted by A and is extended laterally at its base a to form a stable support. The cylinder to be routed is supported, primarily, from the base of the column A, and the cutting-tool, together with a slide and way for conducting the tool along the upper element of surface of the cylinder, are pivoted, primarily, to the top a of the column A, which in the present instance is given a rearward and upwardslant from the body of the column, as clearly indicated in Fig. 2.

The support, vertical adjustment, and rotary adjustment of the cylinder are provided for as follows: A pair of hollow pedestals B B are fixed to the front of the base a of the column and on these pedestals worm-wheels O O 'are mounted, having fixed to rotate therewith nuts Z) Z). The worm-wheels G O are rotated. by worms (not shown) on a shaft 0, mounted in suitable bearings fixed to the pedestals B B, the said shaft being rotated by means of a crank-wheel c. A horizontal wayD is located above the pedestals B B and from it depend screws (1 d, which screws engage the nuts I) b and pass through the worm-wheels G 0 into the hollow pedestals B B. It therefore follows that when the shaft 0 is rotated by the crank-wheel c the wayD and the parts carried thereby will be elevated or lowered by the ac tion of the nuts Z; l) on the screws dd. The way D is guided and held steadily by means of rearwardly-extending arms 61 which have a sliding connection at their ends with depending rods a fixed to the column A. On the way D are mounted a head-block E and a tail-block E. The blocks E E have a dovetailed engagement with the way D and are split, as shown at c, Fig. 2, and provided with a through-bolt e for the purpose of locking them to the way D in any desired adjustment. The blocks E E are connected by a shaft 6 rotatably mounted therein,and provided with chucks c e for holding the cylinder in position on the shaft.

The arrangement for holding cylinders of varying lengths on the shaft e is as follows: The tail-chuck e is made bodily adjustable along the shaft 6 at frequent intervalsin the present instance by means of a pin 6 which extends through the base of the chuck and through one of the openings 6 in the shaft. This serves to locate the two chucks a distance apart corresponding to the length of the cylinder to a degree equal to or less Ice than the distance between two consecutive holes 6 in the shaft, and the two chucks are then drawn into snug engagement with the cylinder-by means of a draw-bolt F, provided with an operating-wheel fiextending through a sleeve f, (see Fig. 4,) in which the headchuck e is held, and into screw-threaded engagement with a socket e in the end of the shaft 6 By turning the draw-bolt F the shaft e with the tail-chuck e fixed thereon, will be moved longitudinally,carrying the chuck 6 toward or away from the chuck e to clamp or release the cylinder, as may be required. The cylinder, no matter what its diameter and length, may thus be clamped in position between the head and tail blocks E E, and by raising and lowering the way D the upper element of surface of the cylinder may be brought into a predetermined position in space ready for operation. When so adjusted, the cylinder may be rotated, together with the shaft 6 as follows: The sleeve f, which carries the draw-boltF and chuck e ,is mounted in suitable hearings in the head-block E, and the wheel G, for operating the shaft 6 and the cylinder thereon, is fixed to the sleeve f, as clearly shown in Fig. 4. A wire g, through which power is transmitted to the wheel G, after passing one or more times around the wheel G extends downwardly upon opposite sides of the head-block E, thence under guide-pulleys g 9 the one at the front and the other at the rear of the way D, the one part extending along the rear of the way D to the upper section H of the tension-drum, to which it is secured after passing one or more times around the drum-section, and-the other part extending along the front of the way D to and one or more times around the operating-wheel I, and thence to the lower drum-section H, to which, after passing one or more times around its periphery, it is secured.

The wire 9 is held constantly under the desired tension by the drum composed of the sections H H, to the former of which, as hereinabove stated, the part of the wire to the rear of the way is attached and to the latter of which the part of the wire at the front of the way is attached. These two sections H H of the drum are mounted to rotate horizontally relatively to each other, the lower section H being in the present instance fastened to an upright shaft h and having the upper section H loosely mounted on the hub of the lower section H. The lower section H has fixed to its upper side a ring 71, having gear-teeth on its periphery, and these teeth on the ring it are engaged by a pinion 77. fixed on a short rock-shaft k extending upwardly through a bearing in the upper drumsection H and having fixed to its upper end a lever-arm h, the free end of which is attached by a spring h with a stud 71 set in the top of the section H. It thus follows that the sections H and H of the drum are connected by means of the pinion k and gearing It, so that, assuming the upper section H to be for the moment stationary, the tension of the spring h, tending to draw the end of the lever k toward the stud h will tend to rotate the lower section H of the drum in the direction to wind the wire 9 at the front of the way on the drum, and hence hold it taut. On the other hand, assuming the lower section H to be stationary, the spring 71 will tend to rotate the pinion k and hence to cause it and the drum-section H, which carries it, to travel relatively to the lower section in a direction to wind the part of the wire at the rear of the way on the said upper section H, and hence hold it taut. In practice the one or the other of the sections H H will give way as the tension becomes too great onit until it is balanced by the tension upon the companion section, so that the two parts will be at all times under equal tension, which is to be primarily determined by the strength of the spring 72 I further provide for the slight raising and lowering of the drum H H as it winds and unwinds the wire to prevent the layers of wire from overlapping one another. This is accomplished as follows: The shaft h has in its upper end an interiorly-screw-threaded socket h which engages a fixed screw h set in the top of the way D and fixed against a rotary movement. The pitch of the screw it is such that as the drum-sections H H rotate and carry with them the shaft h it will, by its screw-threaded engagement with the screw 71. gradually raise and lower to accommodate the position of the wire thereon.

The wire-operating wheel I has fixed to its front a ring 7;, provided on its periphery with gear-teeth which engage a pinion t" on a shaft '6 which extends forwardly and carries on its front end a star-wheel i It is desirable that the star-wheel 6 some one of the arms of which are grasped by the operator to operate the wire g, and hence rotate the cylinder, should be within convenient reach of the operator at all points throughout the length of the cylinder wherever the cutter may be at work, and to this end I have provided means for raising and lowering the star-wheel and also for moving it bodily along the way D without disturbing the engagement of the wheel I with the wire. In the present instance the star-wheel is provided with four arms; but it may be provided with agreater or lesser number of arms, as may be found desirable. It and its shaft carrying the pinion 2" are mounted in a bracket i fixed to or formed integral with a housing t arranged to protect the gearing and provided with a hub i which forms a bearing for the wireoperating wheel I and which in turn is mounted on a hollow axle 1J fixed in the depending front portion of aslide K, fitted to the way D. The axle i is conveniently screwed into the depending front it of the slide and carries a head i at its front end, which serves to hold the hub 11 tightly against the front is of the IIO slide in whatever position the star-wheel may be adjusted in its r'ot'ary adjustment'around the Wheel I. For example, if the star-wheel, when the pinion t" is at the top of the toothed ring 't, be too high the axle 17 may be loosened by applying a wrench to its headt' and the housing t together with its bracket carrying the star-wheeland its pinion t", may be rocked on the axle 11 either to the left or right, the pinion t" working idly in the teeth in the ring 2' until the star-wheel has reached the position desired, and in that position it may be firmly locked by screwing the axle i into the front of the slide, so'as to cramp the hub i firmly between the head i of the axle and the front face of the part 76. In addition to this bodily upward and downward adjustment of the star-wheel it and the parts con-' nected with the slide K may be bodily adjusted along the way D and locked in position by means of one or more vertically-movable locking-pins--in the present instance two, denoted by L and IJ-arranged to move vertically in sockets formed in the depending portion 3 of the slide, as shown in Figs. 5,6, and

7, and having their upper ends wedge-shaped, so that when they are forced upwardly they will wedge between the front of the way D and the rear of the depending portion it of the slide, and hence lockthe slide in position, and when allowed to drop will release the slide K and permit it and the parts carried thereby to be moved along the way D. Power is applied to and removed from the pins L L by means of an angle-dog mounted on a pin Z, held between a pair of lugs 7: 7,0 on the depending port-ion 7c of the slide. The angle-dog is provided with an upright arm Z and with a pair of short forwardly-extending arms, (denoted by Z the position of which are shown in Fig. 6, and one of which, Z is shown in full lines in Fig. 5. The arms Z" extendunder the ends of the pins L L in position to drive the pins upwardly or allow them to drop as the dog is rocked on its support and the upright arm Z of the dog is in position to be engaged by a longitudinally-sliding pin Z resting in the bore of the hollow axle t and adapted to be driven into engagement with the arm Z of the dog or released therefrom by a set-screw P, which extends through thehead of the axle and has a screw-threaded engagement with the interior of the axle. From this it follows that when it is desired to move the star-wheel bodily along theway D to suit the position of the cutter for the time being the screw Z may be turned to release the pin Z from the angledog, which in turn will release the lockingpins L L and permit the slide-K to be moved along the way D at pleasure, the wheel I accommodating itself to its new position by idly rotating under the friction of the wire around it. When the slide K has reached the position desired it may be locked in a moments time by simply turning the screw Z into engagement with the pin l", which by its engagement with the angle-dog willforce the locking-pins L L and cramp the slide K securely in its place, so that when the wheel Z is turned by means of the star-wheel motion will be communicated through the wire to the shaft which carries the cylinder and it will be rocked the one way or the other according as the star-wheel is turned in one way or the other to bring the cylinder in the desired position with relation to the cutter.

The means for moving the cutter toward and away from the cylinder and along the upper element of surface of the cylinder while it is being driven at a high rate of speed are as follows: A horizontal way M is supported on a pair of forwardly-extending arms in m, which arms are pivotally secured to the top a of the column A. In the present instance the top Ct of the column is composed of a pair of upwardly and rearwardly extending arms provided at their upper end with bearings for a rockshaft m to which the arms on m are fixed, so as to rock together with the shaft m in the bearings in the top of the column. The way M extends horizontally along in proximity to the position which the top of the cylinder to be operated upon is to occupyviz., parallel with an element of surface on the cylinder-and supports a carriage N, which carries the cutter, and also means for driving the carriage back and forth along the way M. The carriage N is secured to the way M by means of yielding gibs 7%, (see Fig. 2,) which serve to automatically take up wear. The yielding feature may be obtained by insertinga spring-washer n beneath the nut n which holds the gib in place.

The mechanism for driving the carriage N along the way M is quite similar in its general character to that already described for rotating the cylinder. It consists of a starwheel 0, in the present instance provided with six arms orhandles and carrying a pinion 0, (see Fig. 2,) in mesh with a gear-wheel 0, fixed to rotate with a wire-receiving drum 0 the drum, the gearing, and the star-wheel being all supported in a suitable manner on the top of the carriage N, and the shaft sup porting the star-wheel and its pinion 0 being mounted in suitable bearings in a housing 0 arranged to be adjusted around the gearwheel on the drum 0 to bring the star-wheel nearer to or farther away from the operator in a manner quite similar to that hereinbefore described for bringing the star-wheel i into a higher or lower adjustment. The wire which engages the drum 0 is denoted by P and is fixed at one end to a postp on the way M and at its opposite end is attached to an arm 19, fulcrumed on an adjustable pinp and having its free end connected by a spring 19 with a fixed support 19 The wire is conwill carry the cutter bodily by means of the adjusting-pin 19 to which the arm 10' is fulcrumed and which has a screwthreaded engagement with its support 19 In the present instance the drum 0 attached to the carriage, is carried bodily along the way M with the carriage as it is rotated, taking up and paying out the wire, which has a frictional engagement with it, and this motion along parallel with the way M.

The cutter,which maybe of any well-known or approved form, is denoted by Q and may be fixed to its spindle in any well-known or approved manner, the spindle itself being mounted in a support q, having a vertical adjustment on the face of a forward projection n on the carriage N. In the present in stance the cutter-spindle support has a dove tailed engagement with the front of the part 17., so that cutters of varying lengths may be employed as occasion may require.

To further accommodate the cutter-support q to the rising-and-falling movement which is imparted to it as the carriage and its way are raised and lowered, I provide a jointed and longitudinally-extensible rod g, which extends between the cutter-support q and the spindle 1 on which the intermediate drive-pulley R is fixed. A belt 1" leads from the intermediate drive-pulley R to a pulley R on the cutter-spindle, and a belt 7" leads from a drive-pulley R on the drive-shaft to a pulley R on the spindle (1 which carries the intermediate pulley R. The spindle g is supported in the end of an arm 5, projecting from a bracket S at the top of the column A,and the spindle qiwhich the drive-pulley R is mounted on, is supported in the bracket S and is provided with fast and loose pulleys 3' 8 which are actuated by means of a belt s leading to a source of power. (Not shown.) A belt-shifter of any well-known or approved 7 form operated by a lever-s serves to start and stop the action of the cutter at pleasure. It will thus be seen that the cutter-support g, while its position is determined by the carriage N along a predetermined line, which in" the present instance is parallel with an element of surface of the cylinder, is con nected with its driving mechanism by a jointed arm, which at the spindle g as its joint permits a folding and unfolding of the arm in a horizontal direction, while the jointed rod q permits the slight rise and fall of the whole by t) and which is supported by the pedestals B B and which may be of any wellknown or approved form. The downward movement of the arms m m and the parts carried thereby is determined by means of a pair of adj usting-screws, (indicated in dot ted lines in Fig. 3 and one of them shown in full lines in Fig. 2, denoted, respectively, by u u.) 'By this means the depth of cut of the tool may be accurately determined, and the operator has only to pay attention to the lifting of the tool out of engagement with the work, so far as the upward and downward movements of the cutter are concerned.

The operation of the machine as a whole may be briefly stated asfollows: The cylinder having been placed in position so as to bring its upper.surface in proper relation to the cutter and the cutter having been set in motion, the operator, with one hand on the star-wheel i another on the star-wheel O, and his foot on the treadle t, controls the movement of the cylinder to bring the cutter into engagement with its surface at the proper point laterally of its length, while with the star -wheel 0 he moves the carriage, and hence thecutter, longitudinally along the cylinder to bring the cutter into engagement with the cylinder at the proper position lengthwise of the cylinder, and with his foot lifts the cutter out of and allows it to drop into action at pleasure. The operator thus has under his perfect control by the several adj ustments within his convenient reach means for promptly and accurately bringing the cutting-tool into engagement with the cylinder at any point he pleases throughout the surface of the cylinder, and in addition to this he may operate upon cylinders of varying diameters and lengths as occasion may require.

It is obvious that changes might be resorted to in the form and arrangement of the parts without departing from the spirit and scope of my invention. Hence I do not wish to limit myself strictly to the structure herein shown and described; bu
