WINDING MACHINE.

' Application filed September 29, 1825. Serial No. 59,270.

- The subject matter of this invention is a machine or apparatus for winding flexible chine in which such material is made or fin-.

ished, or is releasedfrom other sources of supply. Other objects are concerned with means for driving a plurality'of spools in order that the winding action may be carried on continuously while filled spools are removed and empty spools substituted; and

also with a construction of spool ada ted to permit ready removal, in the form 0 a coil, of the material wound upon the spool.

The winding machine chosen for illustration herein has been designed for the particular use of winding, into the form of coils, armored electrical cable and flexible metallic conduit adapted to contain electrical conductors; receiving and winding up such cable-or conduit as it is delivered from the machine which makes it. However, the invention is not limited to that special use,

but is applicable to receiving and winding wire delivered from a wire drawing machine, or strip metal from a rollin mill, fabric from a loom or rope, thread, exible tubing, or any other elongated and slender flexible material from any source, which needs to be brought into coiled form or wound on a spool. Hence in the following description and claims, I will explain and treat the invention with reference to its characteristics as a winding machine for any purpose or use which it is capable of servmg, and without limitation as to the specific material handled or the source of such material.

Like reference characters desi same parts wherever they occur in all the figures.

The working parts of the machine are mounted on a frame 10 of any suitable character and construction. The operative and adequate construction shown in the drawings comprises two side frames with transverse braces and tie members, aflording a staple base and separated bearings for the various shafts. j

A shaft 11 is rotatably mounted on the frame, and has a protruding end on which a take-up spool 12 is detachably mounted and fastened. Loosely mounted on the same shaft are a ratchet wheel 13, a pawl carrier 14 carryinga pawl; 15 for driving said ratchet, and a two-armed lever 16-17, the purpose of which will be later explained. There is splined upon the shaft a clutch member 18 having jaws or teeth adapted to be slipped into and out of complemental sockets in the hub of the ratchet wheelfor the purpose of detachably coupling the ratchet with the shaft and, through the latter, with the spool. A clutch shipper 19 is supported on the frame adjacent to the ate the clutch and cooperates with the latterin a well known manner for bringing it into and outof coupled relation with the ratchet .wheel hub. A holding ratchet 20 is also till by a connecting rod 26 with a rocker 27 pivoted at 28 on the frame. The connecting rod may be coupled at any one of a number of different points on the rocker, at different distances from the pivot 28. Such coupling points are designated at 29, 30 and 31. According as the connecting rod is attached at one or another of these points, the rocker is oscillated through a larger or smaller angle.

The pawl carrier 14: is oscillated by the rocker 27 through the medium of a link 32, which is pivoted at one end to the pawl carrier, and at the other end carries a pivot rod 33 contained in a slide block 3 l which occupies an elongated, substantially radial, guideway or slot 35 in the rocker. Une end of this slot preferably entends as near as possible to the pivotal anis of the rocker. and nearer thereto than "the nearest coupling position, 31, oil the connecting rod; while the slot preferably entends farther away trom the pivot than the outermost coupling point 29, According the pivot 33 is positioned more remote from or nearer to the min of roclrer, the pawl carrier is moved through still or less angle and the l 'respondingly rotated by longer or of the pivot 33 in the rocker .tioally controlled by the tension of the material being wound, acting through lever lti -l't, previouslymentioned. The arm 13 oilsaid lever carries a guide 36. which is preferably a roll located in the same plane with the spool, and the elongated flexible material to be wound passes under the guide roll 33 in its course from the source oil supply to the spool. Such material is designated by the numeral 37, and will generally be reterred to hereinafter as the strand; the term strand meaning and including any or the materials or articles previously mentioned, or other similar material which the machine is capable of handlin lt may be assumed that this elongated materiel or strand is delivered from the source oi supply at a limited rate of speed, and that the winding to take up the material at an average rate equal to t 1e rate of delivery, in order that a suficient tension may be maintained during winding, but that too great a tension may not be applied, with danger of breaking, stretching or otherwise injuring the strand. To this end, the lever arm 16 18 made Suficiently heavy to apply tension to the strand 37 and to descend when the strand slackens; but its weight is not great enough to stretch the strand unduly or to prevent the strand from raising it when the slack in the strand is taken up. Preferably the weight of this part is made adjustable to the strength and character of the strand by providing .de-

machine is required tachable weights 38 hung from the lever by a suspender 39.

The arm 17 of the lever is coupled by a link 40 with the pivot 33 of the pawl driving link 32. A satisfactory mode of thus coupling said link and ivot together is to make the pivot of suffiolent length to protrude through an eye in the end of the link and to secure a collar or nut 41 on such protruding end. It will be apparent that if the strand 37 slackens, the weighted arm descends and the other arm rises, thus raising the pivot 33 and increasing the stroke of the driving pawl; while it the strand tightens, due to its speed of delivery being less than the take-up rate of the spool, the weighted arm 16 is lifted and the pivot 33 is lowered and brought toward the pivot of the rocker, thereby shortening the swing of the pawl carrier and the steps of rotation of the spool.

The spacing of the ratchet teeth and the dimensions, proportions and positions oi the transmission mechanism between the pawl carrier and the driving shaft 22 are appropriately designed for tie work which the particular machine made according to this invention is intended to perform, and made of such values and with such effect that the limits oi peripheral speed oi the spool will be within the limits oi delivery of the strand; and preferably also of such values that no motion at all will be given to the spool when the strand is drawn straight, or approximately so, between the deliverypoint and the spool. The latter ellect is accomplished by making the spacing of the ratchet teeth greater than the movement imparted to the pawl when the pivot 33 lies in its position of nearest approach to the rocker pivot. This condition occurs when delivery of the strand is stopped, the takenp spool being thereby automatically stopped also.

The regulating means just described auto matically takes care of the increasing travel of the surface on which the strand is wound, due to accumulation of windings on the spool, as will be readily apparent. A sufiiciently exact correspondence of the average peripheral speed of the spool with the rate of delivery of the strand is obtainable, even without making the ratchet teeth of fine pitch, because when the condition is reached that a single step of the spool moves its receiving surface a distance substantially, greater than the length of the strand delivered in the time between two oscillations of the pawl, the tightening of the strand caused thereby simply suspends the movement of the spool until enough slack has accumulated in the strand to permit the spool to be turned another step.

The spool is mounted on the shaft in the manner previously described in order to permit of its removal when filled and the substitution then of an empty spool. A second spool 42 ismounted in a similar manner to the mounting of spool 12 u n the end of of a shaft 43. On the sha 43 are also mounted a sprocket wheel 44 and a hold ng ratchet wheel 45 co-acting with a holding pawl 46. The sprocket 44 is connected by a chain 47 with a sprocket 48 rotating on an intermediate shaft 49; and a second sprocket 50 on the same shaft is connectedb a chain 51 with a sprocket 52 connected rigidly with the ratchet 13. The sprockets 48 and 50 may In order to compensate for wear and stretch of the sprocket chains and to take up.

their slack, the shaft 49 is preferably mounted in bearing boxes. which occupy inclined guideways 56 on the frame and are ad- ;iusted therein by screws 57.

1 The spools which Ihave shown 111 these drawings are designed to release the strand as a coil after being wound up, and to this end, each spool is made of two parts, each consisting of a flange 58 and a hub 5 9, and each part having a central hole to receive the shaft. The hubs also have notches 60 soarranged as collectively to form a recess within which the end of the strand maybe inserted to hold it before commencing to wind, when the stand is of strliicient stifi construction to be so held; and one of the spool members is provided with a dowel 61, adapted to enter a recess in the other, for so positioning the parts, when assembled, that the notches will register.

In thus above particularly describing one embodiment of my invention, I have not intended to limit the protection which I seek to that specific machine, or in any other manner than commensurate with the novelty of the invention. Various inversions, reversals and modifications in the structure and arrangement of the machine and its parts may be made, and equivalent structures and parts substituted, without departure from the invention.
