TO ALL WHOM IT MAY CONCERN: v

Be it known that I, W'ILLIAM I-I. ABEL, of Grcenville, in the county of Providence, and State of Rhode- Island, have invented a new and improved Device for Converting Motion, of which the following is a full, clear,

and exact description, reference being bad to the accompanying drawings, making part of this specification,

in which- I Figure 1, sheet 1, represents a longitudinal vertical section.

Figure 2, a plan or top view.

Figure 3, a central section of a pulley which has a'tumbling, lever, y, instead ofa sliding shipper, B, as seen in figs. l and 2.

Figure 4, sheet 2, is a side, and

Figure 5 an end elevation.

Figure 6, a'transverse elevationon the line A Bot fig. 4.

Figure 7 is a plan, and i Figure 8 an edge View of one of the segmental slides,"e, with a friction-spring attached, and shows its position on the cylinder A.

This invention relates to that class of devices which are employed for converting rotary motion into reciproosting motion, either rectilinear or curvilinear, and it may be employed for a traversc moticnor a parallel motion, or in the place of a mangle motion, and therebyai'oi-d the necessity and inconvenience of calculating the nice and accurate gears and mangle-pins, or segments of pins or teeth, which are requisite in all such geared works. K

When my improved device is used for a traverse motion, as in a'knitting-machine, to traverse thc feed or thread-carrier along, over, or in close proximity with the needles, the cord or chain a, (shown in red lines, fi'g. 2,) may pass round a grooved wheel, 1), arranged on an arm, L, thence to and around-asimilar'whcel, b,'back' round a like wheel, b and 0d over the operating-cylinder, wheel, or pulley, A, and connected withthe ear or ears (2 of the segmental slides e. The cords or chains a, whi'ch run around the pulley 6 only, and'connect with the ears e, are shown in black lines. The feed-guide and thread-carrier or other suitable part of theknittingmachine feed, maybe connected with the cord or chain is, at a: or at v, and the feeding-device made to traverse steadily any distance within the scope of the diameter of the wheel A, and the distance of such traverse may be considerably varied by releasing the but 9 fig, 6, and moving the .stud h ,andplate I,-in' the curved slot 7;, upward to lengthen, and downward -to shorten the motion, by-' carrying the pivoted oscillating lever 0 higher: or lower, so as to bring the shipping-pin, c, projecting from the sliding shipper B, earlier or later into contact with the sides of the oscillating-lever, and upward against the forked or enlarged endf, all as clearly, shown in figs.

2, 4,;md 5. A 'Curvilinear reciprocating motion in this device is where the cord or chain 11 passes around the'pulley b, or a much larger pulley, that will not be turned so far by the action of the pulley A, the circumferehtially moving segmental slides e and shipper B; or the same motion may be reversed by the ilse of gears on the shaft of the pulley b, engaging with some other gear connected with the device to which said motion is to be given,

Horizontal or vertical reciprocating motion may be had from rotary motion in this device, either longitudinally or transversely with the machine or apparatus to which it is connected, or with which it operates, by a connecting cords or chains,a (shown in red lines infig, 4,) with the upper and lower-portions or extremities of the oscillating-lever G, and running saidcords or chains over pulleys 6 which rotate on pins projecting from stands, is, secured to one of the ends D, or supporting-frame, or at any other reasonable distance from the wheel A, and connected with some other support; or anoscillating lever, E, may be operated with a slow, steady motion, or with a sudden and forcible motion,,like the shuttle-motion of a loom for weaving, by connecting the extremities of the lever E and the lever G by cords or chains, a and by rotating the wheel slowly. or rapidly, apcording to the velocity or suddenncss of the motion required. The object to be moved vertically may be attached to the card a at 7, or to that part of the s'aid'cord.

In constructing the cylinder A, (as shown in figs. 1, 2, 4,.and 5,) the lateral annular grooves m, (show n 1n fig. 1, near the centre of its length,) may be formed in the substance of the wheel, and the similar grooves, n, at the ends of the cylinder, may be formed in the sides of disks or plates, F, which are fastened to the ends of th'e cylinder, or all the grooves may be formed in the substance-of the wheel, as'shown in fig. 3. The edges of the segmental slides 0 enter the grooves m and n, and move round the cylinder in said grooves. The inner surface of each slide bears against the face of the cylinder. The tail, i, of each friction-spring also bears on the face of the cylinder as the slides move round, and prevent any slipping or sudden action of said slides in a wrong direction. The shipper B is fitted into the cylinder A, flush with the face or periphery, and the slides e pass over the shipper as they move round the cylinder. A projection, R, is formed on or fastened to the outer surface of the shipper B, and a. radial shifting-pin;c, projects therefrom. This shifting-pin acts alternately against the sides of the oscillating-lever C, at each revolution of the cylinder A. Said lever is pivoted to the plate I of the stud h, and swings freely on its pivot Zwhen acted upon by the pin 0. The top endfof the lever O is forked, or it-may besolid, and of the same form, so that when thecylinder A is rotated, and the shiftingpin passes round on one side of the lever C, and upward to and in contact with one fork thereof, the lever is' swung sideways, the next revolution of the cylinder A carries thepin c to the opposite side of the lever, and upward-in contact with the other fork, throwing the lever to the other side. To prevent the oscillating-lever being thrown too far each way by the action of the pin c, I employ an adjustable stop, S, (shown in figs. 2 and 5,) at each side of said lever, and alittle below or above the pivot Z thercofl And when the pin 0 forces or throws the top of the lever over in either direction, the lower portion of said lever comes in contact with one of these steps, which prevents excess of motion or oscillationoofxsaid lever, the vertical portion, or plate 1), of said stops being fastened to the plate I by a screw, 8. This alternate action of the pin a and the lever G operates the shipper B, first oneway, then the other, throwing the portion R or projection into the path of one of the slides, e, and out of the path of the other slide, and vice versmthus allowing first oneslide to pass around the cylinder inthe direction of its rotation,'a'nd the other slide in the opposite direction, and then the rotary motion or rotary sliding action of the slides to change at every revolution of the cylinder, each slide being stopped; at the changing-point at every other revolution, by the shipper B or the projection R thereof. The

cords or chains (1, having their endsconnectedwith thev cars 02 of the slides e, and passing around pulley 6,, or a series of similar pulleys, give a reciprocating motion to said pulley or, pulleys and the cord a, or a suitable traverse motion, or'other motion, as dcscribed to the object or device connected with such cord or chain a or a, and arranged to slide, traverse, swing, or oscilhiteas specified.

By the employment of grooved pulleys, properlydocated, as, for instance, the pulley 6', shown in red lines in fig. 2, the cord or chain a may be carried from pulley t around pulley b and thence at an angle (as shown) to pulley b and a proper device made to traverse on said angle,o or any other angle between a longitudinal and transverse line, or any of the other motions herein specifiemmaybe obtained or performed by the same or a similar connection and arrangement of pulleys and cords or chains connected with and actuated by the wheel A and oscillatingdever or levers and the .connectiousshown and described} In making my improved device one large scale, I generally employ an arm-pulley, as shown in section in fig. 3, in which case the shipper B is substituted by the tumbling or'rocking-lever y, whichswings in a. slot made through the rim G of the pulley, and is pivoted to an ear or stand, 19, projecting from the side of the hub H, the outer end, a, of said lever'being formed similar to the shifting-pin 0, shown iufigs. 1, 2, 3, and 4, and made to perform the same operation in connection witlra similar but larger oscillating lever, O, constructed and applied in the some or in a similar manner. 7

Motion is given to the cylinder A and all the-other moving parts of the device and connections by means of the crank e on the'shaft W, or by a belt or band running from some rotating driving-pull ey on to a pulley placed on the shaft W, or by suitable gears arranged forthat purpose.

Theobject of this invention is to convert a rotary motion into a reciprocating rectilineanpr curvilinear motion, to take the place of toothed wheels and toothed or. pin-segments, for a mangle-motion, to serve as a parallel or a traverse motion, either slow and steady, or sudden, and with greater or less force or velocity, and longitudinally or transversely, horizontally or vertically with themachine or apparatus, or on any angle between such longitudinal and transverse lines, or betweena horizontal and a. vertical line, all as clearly shown and described. i I i d What I claim as new, and desire to secure by Letters Patent, is-- p 1. I claim the cylinder A, constructed substantially as shownv and described, viz, with annular grooves m and n, andprovided with slides e, shipper B, and pin a, or a tumbling-lever, y, or the equivalentithereof, said cylinder or pulley being applied to a central shaft, W, and arranged for operation substantially as and for the purpose or purposes-set forth.
