WINDING MACHINE.

Application filed November My invention relates to the class of .machines employed for depositing threads by a winding operation upon a. support, and an object of the invention, among others, is the production of a machine of this class whereby the winding operations may be rapidly conducted in a particularly efficient manner.

One form of machine en'ibodying my in vention and in the construction and use of which the objects herein out, as well as others, may be attained, ilhiistrated in the accompanying drawings, in which- Figure 1 is a top view of a machine embodying my invention.

Figure 2 Sheet II) is a view in front elevation of the same.

Figure-3 (Sheet III) is a view in end elevation.

Figure 4 is a detail view, scale enlarged, illustrating the construction of a flier and its support.

Figure 5 i a detail view, scale still further enlarged, in section through the fliers, their supports and the driving mechanism therefor.

Figure 6 (Sheet II) is a detail view in vertical section through a portion of the machine ona plane denoted by the dotted line 66 of Figure 1, the ucale being the same as that of Figure 1.

Figure 7 (Sheet I) is a detail view, scale enlarged, illustrating the construction and operation of the mechanism for imparting reciprocating movement to the thread form supporting bars Figure 8 is a detail view illustrating the mechanism as winding the thread upon the thread forms when the winding starts at the base of said forms.

lVhile this invention particularly contemplates the deposit: of threads upon forms from which said formed masses are subsequently removed, yet it is to be understood that the invention is not confined to a machine in which the deposited threads are to be subsequently removed, as the invention in many of its forms will be found applicable to machines of various constructions whereby thread may be deposited upon a core or form irrespective of the fact as to whether such formed mass is or not subsequently removed from the support for such mass.

In the accompanying' drawings the numeral 1.0 (161101363 the bed of the machine construction the balls of box form comprising ends 12 and a front 13 rising from the bed, the back being open, as illustrated in igure 1. A driving shaft 14 is supported in a bearing 15 at the upper end of a bracket 16 rising from the bed and is driven as by means of a belt passing around a pulley 17. A bevel gear 18 is mounted to rotate on the shaft 1 1 and meshes with a bevel gear 19 rotatably supported at the upper end of a bracket 20 rising from the bed 10, the gear 19 meshing with a bevel gear 21 secured to a connecting shaft 9 rotatably mountedin the front 13 vand having a thread-form reciprocating pinion 22 secured thereto, one end of the shaft 1d being mounted in the bevel gear 21, but for rotation independently thereof. A clutch member 23 is splined to the driving shaft 14 and has clutch pins arranged to engage clutch pins on -'the gears 18 and 21, in the position of the parts shown in Figure 1 the clutch member 23 being engaged with the gear 21, and the mechanism being under operation to wind thread as shown. A clutch lever 24 is pivotally supported on'a post 25 rising from the bed 10, th is lever being forked and having pins engaging within a groove in the clutch member 23 in a manner that will be readily understood.

A clutch actuating lever 26 is pivotally supported on the bed, as shown in Figure 6 of the drawings, one end of this lever being pivotally attached to the clutch lever 24 and its opposite end being pivotally attached to a clutch actuating rod 27 .slidably mounted in the front 13 and in a hracke; 28 secured to one of the ends 12, said rod being in two sections united by a connector adjustablv secured to each section, as shown in Figures 1, 2, and 3 and having a clutch actuating knob 29 secured to its outer end, as shown in Figure 1 of the drawings.

A flier driving gear 30 is secured to the connecting shaft 9 and meshes with one of a train of flier gears 31 rotatably supported by the front 13 and successively meshing one with another as shown in Figures 1 and 2, said gears being mounted upon hollow studs extending through said front and forming thread guides 32. Fliers are secured, one to O ing gear 4:0, each oi which gears is secured each of the gears 31, said fliers each having thread guides 341 projecting therefrom to receive threads extending from spools or bobbins 36 rotatably mounted on supports rising from the bottoms of thread boxes 37 located underneath the machine frame, said threads passing through the thread guides 32 in the front 13 and through the guides 3 1 on the fliers 33, as shown in Figure 1.

A thread-form reciprocating pinion 2-38 is secured to rotate with a flier gear 39 at that end of the train of flier gears opposite to the gear 30, and each of the pinions 22 and inesheswith a thread guide reciprocatto a thread-form reciprocating shaft 11 rotatably mounted in the front 13 and in a bracket 28, there being one 01 these brackets secured to an end 12 at each end oi the marhine. Each of said reciprocating shafts is threaded (in opposite directions in the structure shown herein) to engage a threaded hole in a traveler 42, said travelers each supporting one end of a thread-form supporting bar d3 extending across the machine from end to end, and as shown in, Figure 1 oi the' drawings.

Thread-forms 1 1 are secured to and extend from the bar 13, these forms being arranged in sets, each set being secured to the opposite side of said bar from the other set, and the members of each set projecting outwardly away from the bar. Each of: these thread-torins is forked and each ot said forms has thread receiving notches 415 at its base and thread receiving notches 4-6 at its end, these notches being shaped to pinch the thread and serving a means 01% attachment of the end of a thread when it is first secured to a thread-form. The travelers are guided in their movements by a guide engaging each ot them, these guides being in the form of rods, one of which guide rods 17 is located at one end of the machine, and the clutch actuating rod 27 serving as the other guide, both of which pass through the travelers 12 to guide it and prevent cramping action thereof.

Stop collars 18-49 are secured to the rod 27 on opposite sides of the part of the traveler engaging said rod, these collars being spaced a proper distance apart to effeet a stopping operation at the proper time.

Theoperat-ion of the machine is as follows:

To start the operation of the machine the threads are each extended through the guides 32 in the ends 13 and through the guides 34 on the fliers and the end of each thread is then engaged with a notch at the outer end or at the base of a threat form, depending upon the position of the shown in Figure '8, the threads will be en- Q gaged with the notches at the bases of the thread forms.

Assuming that the bar 18, at the beginning of the operation, is substantially in the position shown in Figure 1, and that no thread has been wound upon either of the sets ot' thread-forms, and that the threads are engaged with the notches at the outer ends of said forms, and that the machine has been set in operation and that the winding has just begun, the fliers operating as shown in Figure 1, will sweep around the thrcadt'orms in opposite directions, that at the right rotating in a clockwise direction, when looking'from the front of the machine, and the thread guide reciprocating shafts -11 will be rotated in a direction to cause the thread-il'orms 1 1 between the bar 1-3 and the trout 18 to travel toward said front. In this ,qaeration the clutch member23 is engaged with the clutch member on the gear 21, which parts are driven by the shaft 1 1 and the pulley 17, power being applied through the clutch member 23 and gear 21 to the connecting; shaft 9 and by the latter to the intermeshing gear 30, &c., the gears 18 and t9 rotating idly. This describes the beginning of a winding operation and not a continued operation shown as taking place in Figure 1. oration, the thread-form supporting bar 413 should be at the opposite end of its path of: THOVGHIGHt from that shown in Figure 1 the threads would be engaged with the notches 4155. at the bases of the thread-forms, from which the winding operation would start, as shown in Figure 8, this figure, however, showin g the parts as operated in a continued winding operation and not at the beginning of a winding operation.

Let it now 13021551111166. that a continued winding operation is taking place, this after the thread has been wound upon the forms shown at the opposite and front side of the bard? In this operation the parts will be rotating above described. As the bar 413: approaches the end of its path of movement nearest to the front 13 the stop. 48 will be engaged by the traveler 4L2 at the right hand end of the machine, the rod 27 will be pushed inwardly and as a consequence the clutch member s3 will be disengaged from the gear 21 and the operation of the machine will! cease, this taking place when the thread has been wound along the forms to: the bases, of each of said forms.

During this operation the operative cuts It, at the beginning of the opthe threads that pass from the thread-forms at the front of the bar 43 to the thread-forms on the back of said bar, and on which the thread is being wound, inserts one of the branches of a U-shaped holder 51 through the opening between the forks of each thread-form so that the legs of each holderlVhen the holders have been secured as above set out the thread masses are removed from the thread forms.

After the machine has been stopped, as above described, and the wound masses have I been removed from the forms extending from the front of the bar 43, as above described, the operative rotates thethread bar to locate the thread-forms at the front and the forms from which the thread masses have been removed at the back of the bar 43, theithreads now extending from the outer guide 34 on each of the fliers straight to a wound thread mass on a form at the front of the bar 43. The knob 29 is now pulled out, it having, in the previous winding operation been pushed in, and the clutch members are engaged as shown in Figure 1, and the winding operation starts as shown in said figure. As this winding operation starts the threads are passed to the opposite sides of the wound thread masses at the front of the bar i3, across said bar and around the thread-forms on which the winding is to take place, as shown in Figure 1, after which the operation proceeds as above described.

In the mechanism as herein illustrated each of the thread-forms consists of two members, one 53 of which is pivotally1nount ed in the bart3, such pivoted member in fact comprising the pivoted member of two thread-forms located on opposite sides of said bar, that is said member projects through the bar the other member 54 of each thread-form also projecting through and being rigidly secured to the bar 43. A threadform expanding and contracting bar 55 is pivotally attached to each of the pivoted thread-form members above described, as shown in Figure 1, this bar 55 having a pin 56 engaged in a cam slot in a disc 57 secured to a thread-form expanding and contracting shaft 58 rotatably mounted in the bar 43 and having a thread-form expanding and contracting wheel 59 secured to each end by means of which the thread-forms may be expanded or contracted as occasion may demand. In the winding of some threads it becomes necessary to contract the threadforms in order that the wound masses may be readily removed, and the mechanism described affords ready means for doing this, just before the thread masses are removed, and for again expanding said forms preparatory to receiving wound masses of thread thereon, the wheels 59 being located at each end of the shaft 58 so that one will be always located in front of the bar 43 and readily accessible for the purpose specified.

The barlet3'is provided with means for frictionally retaining it in different winding positions, this means comprising a collar 60 secured to said bar and having recesses to receive spring pressed detents 61 located in sockets in one of the travelers 42, and as shown in Figure 7 of the drawings.

The fliers 33 are each adjustably mounted, being secured to a flier base 62, the latter being adjustably secured upon a hub of oneof the'gears, 81 or 39.

In accordance with the provisions of the patent statutes I have described the principles of operation of my invention, together with the device which I now consider to represent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative an that the invention may be carried out by other means and applied to uses other than those above set out.
