BELT-GEARING FOR WINDING-MACHINES.

Specification of Letters'Patent.

Patented May 7, 1912.

To all whom it may concern Be it known that I, BENJAMIN GRIDLEY, a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented anew and useful Improvement in Belt-Gearing for Winding-Machines, of which the following is a specification.

The present invention has reference to an improvement in winding machines, and more especially in that type of winding ma chine wherein bobbins of varying diameter, generally known as cone bobbins, are employed.

It relates particularly to the means or mechanism for driving the spindles whereon these bobbins are mounted, and it comprehends essentially a mechanism for varying the speed of revolution of said bobbins to correspond with the lifter motion, uniformly so that as the yarn is laid upon the larger portion or diameter of the bobbin, the speed will be uniform with that when the yarn is being laid upon the smaller portion or diameter thereof. This result is obtained, briefly, by the employment of a cone drive with which a device for shifting the belt connecting the cones is associated, said device being automatically operated at predetermined in tervals to shift the belt toward one end or the other of said cones, thereby varying the speed of rotation of the shaft from which the bobbins are driven.

A structural embodiment of the invention is illustrated in the accompanying drawings, wherein,

Figure 1 is a plan view of the machine, showing the cone drive and the lifter and builder motions, the spindles and the shaft for operating the same being omitted. Fig. 2 is a front elevation of the complete machine. Fig. 3 is an elevation of the left hand end of the machine. Fig. 4 is a transverse vertical section taken on the line 4 4 of Fig. 2. Fig. 5 is an elevation of the right hand end of the machine frame, and Fig. 6 is a detail side elevation of the lifter and builder motions, and the operating mechanism therefor.

In said drawings 1 indicates the power shaft of the machine, which shaft is equipped necting said end pieces.

pulley. In addition to the pulleys 2 and 3 above referred to, shaft 1 carries a cone pulley 5 connected by a belt 6 with a reversely-arranged pulley 7 mounted on a shaft 8 arranged below and parallel with shaft 1, both shafts being journaled in an auxiliary frame which is indicated generally by the numeral 9, and is located at the side of the adjacent end piece 10 of the main frame 11. Said frame 11 consists essentially ofthe two end pieces 10 and 12 and the front and rear side rails 13 and 14 c011- This frame supports the builder and lifter motions, and the bobbins and their spindles described hereinafter, while the auxiliary frame 9 supports the driving mechanism, as will be understood.

In the upper portion of the main frame is located the drive shaft 15 which is journaled in the end pieces 10 and 12 and carries a series of pulleys 16, the number of such pulleys corresponding to the number of pairs of spindles 17 with which the machine is furnished, the spindles being arranged in two rows disposed upon opposite sides of the machine and supported in suitable bearings 18, mounted on horizontal rails 19 which are secured to the frames 10 and 12. The guide brackets 21 are secured to and supported by the rails 19 by the lateral arms 20 formed centrally upon the guide brackets 21 wherein the lifter rods 22 are slidably supported. To further steady said spindles,

they are caused to extend through additional bearings 23 mounted upon a pair of upper rails 24 that also serve to support the brackets 21 by reason of the arms 25 carried by said brackets 21. No limitation to the exact structure above described is, however, contemplated, since the lifter rods, the spindles, and the several rails may be supported in any other manner and by any other means deemed expedient. The spindles carry the cone-shaped bobbins 26.

To effect the rotation of the spindles, each is provided with a pulley 27, the pulleys of each pair of oppositely-located spindles being connected by a belt 28 which passes around the corresponding pulley 16 on the drive shaft 15, the diameters of the spindle pulleys being sufficiently less than those of the shaft pulleys to insure their being positively driven by the latter pulleys. The rotation of the drive shaft itself is obtained from the lower cone shaft 8, preferably by means of a belt 29 which connects the pulley 30 on said cone shaft with the larger pulley 31 on the adjacent end of said drive shaft, said belt passing around an idler pulley 32 journaled on a suitable bracket 33, secured to the auxiliary frame. By reason of this direct transmission drive from shaft 8 to shaft 15, the speed of the latter shaft will be directly proportional to that of the former, as will be understood, and in like manner will directly affect the speed at which the spindles revolve, owing to the connection of said spindles therewith. Any variation in the speed of said cone shaft will therefore result in a corresponding variation in that of the drive shaft, and consequently, in the speeds of the spindles and bobbins, as will be apparent.

At the opposite end of the drive shaft 15, from that on which the pulley 31 is mounted, there is provided a second pulley 34 connected by a belt 35 with a pulley 36 carried by a short shaft 37 journaled in the end piece 12 of the main frame. This shaft also carries a gear 38 which meshes with and drives a larger gear 39 secured to a. second short shaft 40 journaled in said end piece above shaft 37 and carrying a double gear 41, said double gear meshing with a larger gear 42 of the same character which is mounted on the shaft 43 that operates the builder motion. While the mechanism comprising said builder motion may be of any preferred character, it is here shown as including a rocker 44 actuated by a suitable cam 45 and having one end of the chain or other flexible element 46 connected to it, the cam referred to being mounted on the builder shaft 43. The other end of chain 46 is fastened to a lateral arm 47, secured to the adjacent rock shaft 48, which latter carries the lifter arms 49 upon which rests the lower ends of the lifter rods 22. Shaft 48 is also provided with an arm 50 carrying the usual counterbalance weight 51 and is connected with the other rock shaft 52 by the lever system 53, as is customary. The rocker 44 to which chain 46 is connected at one end, is carried by a shaft 54 journaled in the frame, and said chain is trained over apulley 55 mounted in a bracket 56 suitably supported in said frame. The builder motion operates in the usual manner to impart an endwise reciprocatory movement to the lifter rods 22 which latter carry the guide rails 57 upon their upper ends, the actuation of said builder motion being effected by the rotation of shaft 43 which is driven from shaft 15 as above described.

Above shaft 43 there is arranged a shaft 58 connected therewith by the intermcshing gears 59 and 60. Shaft 58 extends the entire length of the main frame 11 and projects at one end past the end piece 10 and toward the auxiliary frame 9. On its projecting end, this shaft carries a grooved cam 61 arranged to engage a lateral pin 62 secured to the upper end of a vertical arm 63 which is mounted on a rock shaft 64, journaled in frame 9, said rock shaft being acuated consequent upon the rotation of said cam. Arm 63 and its pin 62 constitute the actuating elements for the variable speed mechanism, such mechanism including essentially a frame for shipping the driving belt 6 and devices for imparting a reciprocatory movement to said frame. In the construction illustrated, there is provided a pair of pivoted uprights 65 and 66, the former of which is carried by shaft 64, and the latter by a pin 67 fastened in frame 9. These uprights are pivoted at their upper ends to the ends of the horizontal upper member 68 of the triangular shipping frame formed of the horizontal member 68 and the two depending members 70 and 71 of said frame. The horizontal member 68 carries the centrally located shipping fork 69 while the shipping fork 72 is carried by the connected ends of the members 70 and 71. The arrangement above described provides, therefore, for a rocking movement of the shipping frame from one side to the other consequent upon the oscillation of shaft 64 by the cam, pin and arm construction 6162-63. The movement thus imparted to said frame will have the obvious effect of periodically shifting or shipping the driving belt first in one direction upon the cones 5 and 7 and then in the other direction, and since the said cones are reversely arranged with respect to each other, these movements of the belt will produce corresponding variations in the speed of rotation of shaft 8, which variations will produce, in turn, proportional variations in the speed of the drive shaft 15 and its associated spindles and bobbins.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

In a machine of the class specified, the combination, with a drive shaft; of a pair of reversely-arranged cones; a belt connecting said cones; a pair of pivotally-mounted parallel upstanding members; an inverted triangular frame pivot-ed at the ends of its base to the upper ends of the adjacent upstanding members, said frame being provided at its apex and centrally of its base with forks engaged with said belt; a second shaft; driving connections between said In testimony whereof I have signed my shafts; a pin secured to one of said upstandname to this specification in the presence of ing. members; and a grooved cam secured to two subscribing witnesses.
