4 Claims.

This invention relates to a wire covering machine, and more particularly to mechanism for winding wire with lamentary m-aterial in superposed layers for wear resistant or insulating purposes.

One object of the invention is the provision in a device of this character of a mechanism which comprises supporting frames adapted for adjustment relative to each other, carrying respectively winding and after treating means for laying filaments upon the Wire and after treating the same to form a compact and cohesive covering.

Another object' ofthe invention is the provision of means for laying a plurality of filaments spirally about a wire `in generally superposed relation with each other during a single winding operation.

A further object of the invention is the provision of a mechanism of the character described provided with wire winding and after treating means arranged for successive operation to suitably apply filaments to the surface of the wire and subject the wireand filaments to appropriate after treatment for retaining the filaments in their wire covering positions and incorporate them into a unitary structure.

Other objects and advantages of the invention relate to various improved details of construc` tion and novel arrangements of the parts as will be more fully set forth in the detailed description to follow.

In the embodiment of the invention illustrated herein, I designates generally a supporting frame which may be of any suitable or desired character and may comprise a base 2 provided with spaced upright standards 3 mounted thereon base and secured in fixed position thereon by means of a clamping sleeve 5. Spaced arms 6 carried by the base are adapted to support a reel 8 carrying the wide to be treated, and a guide member 3 is provided for guiding the wire I from the reel 8 to an opening II formed in the tubular `guide member 4, in order that the wire may pass upwardly in the guide member 4 and through a restricted opening formed in a guide plate I2 positioned within the tubular member 4 at a point adjacent to the upper end thereof for maintaining the wire I0 in a relatively xed position as it passes upwardly from the tubular-member 4.

A table I4 is mounted for rotation about the tubular member 4, being supported for rotation on the tubular member by means of supporting plates I which maybe secured to the tubular member 4 in any suitable or desired manner to provide bearings for the table I4. The table I4 supports a plurality of thread carriers I6 and a corresponding number of thread guides I'I for guiding threads 'or filaments I8 from the carriers to the wire Ill. Each thread guide I1 may comprise a fixed section I9 and a movable section adjustably connected with each other and adapted tobe secured together in vertically adjustedpositions by means of suitable clamping connections 2 I.

The table I4 is provided with an edge groove 22 to receive a driving belt 23 driven from a pulley 24 carried by the shaft 25 of a motor 26. The motor 26 may be secured to and supported u by the auxiliary frame 28 through connections 29, as shown herein, or may becarried by separate supporting means mounted upon the base 2 if desired. When the motor is supported from the auxiliary frame 28, as shown herein, the lower portion of the motor shaft 25 may be mounted for rotation and longitudinal sliding movement in a bearing sleeve carried by or suitably supported from the base 2, in order to permit operation of the mechanism in different vertically adjusted positions of the motor 26 relative to the base 2. It will be understood that the pulley 24 carried by the shaft 25 is adapted to be xedly secured to the shaft in any one of a plurality of vertically adjusted positions, in order to position the same in driving relation with the table I4 in different vertically adjusted positions of the motor 26. In this way, vertical adjustment of the auxiliary frame 28 may be had while permitting rotation of the and a tubular guide member 4 carried by the 55 table AI4 from the shaft 25 through the pulley 24 and drive belt 23 in all vertical positions of the motor 26.

The auxiliary frame 28 is mounted for vertical adjustment on the standards 3, and is held in any one of a plurality of adjusted positions thereon by nuts 34. While two spaced standards 3 are shown herein as supporting the auxiliary frame 28, addi-tional supporting standards may be employed for this purpose as may be found desirable, and such additional standards may be arranged in pairs and provided with nuts or other holding means for supporting the auxiliary frame in various adjusted positions relative to the base.

The auxiliary frame 28 may comprise a transverse frame member 35 receiving the upper end portions of the standards 3 and a rearwardly extending frame portion 36 forming a receptacle 31 having a cover 38 and adapted to receive wax or other coating or impregnating material as indicated at 89, in a liquid or semi-liquid state suitable for impregnating or coating the filamentary material to increase the insulating or wear resistant qualities of the covering. A pair of transverse rods or rolls 40 are carried by the portion 36 of the auxiliary frame and located within the receptacle 31, being positioned below the surface of the liquid 39 therein to guide the wire I below the surfa-ce of the liquid after the application of the laments to the wire.

A second tubular guide member 42 is adjustably mounted in the transverse frame member 35 and a set-screw 43 is provided for holding the tubular guide member 42 in any one of a plurality of vertically adjusted positions in the frame member, depending upon lthe vertical positioning of the auxiliary frame 28 with respect to the base 2 and the desired spacing of the guide member 42 from the guide member 4 for applying the filaments 'to the wire. A guide plate 44, having a restricted guide opening formed therein is positioned within the lower end of the tubular guide member 42 to co-operate with the guide plate I2 for maintaining the wire IIJ in a definitely xed location as it receives the laments from the carriers I6.

Vertical standards 45 are carried by the frame 28 to support rotatably a guide pulley 46 for guiding the wire I0 as it passes from the tubular guide member 42, and similar standards 41 support a drawing roll 48 for carrying the treated wire after its passage under the guide rolls 4D and through the after treating bath in the receptacle 31.

The drawing roll 48 not only supports the wire f but carries a multiplicity of turns of the treated wire, which may be of a number suflicient to extend nearly the length of the roll 48. The roll 48 is provided at one end with a drive pulley 50 carrying a drive belt 5I by which the roll 48 may be driven at a constant speed from the motor shaft 25. The opposite end of the roll 48 is `provided with a drive pulley 52 for driving a spool 54 on which the finished wire is to be wound.

Rearwardly extending arms 55 support a spool 54 for receiving the wire after it leaves the roll 48, the spool 54 being driven from the Pulley 52 through a drive belt 53 and pulley 56 carried by the spool shaft 51. Resilient driving means (not shown) may be employed between the spool 54 and the drive pulley 52 carried by the drawing roll, together with any suitable slip connection for obtaining the necessary variation in axis speed of the spool 54 as the Wire is wound on the spool, without exerting a pull on the drawing roll or otherwise interfering with its operation. For driving the drawing roll 48 from the shaft 25, as well as the wire traversing mechanism, a pulley is carried by that portion of the motor shaft 25 located upon the opposite side of the motor 26 from that to which the pulley 24 is secured, and a belt 6I operatively connects the pulley 60 with a pulley 62 carried by an idler shaft 63 supported rotatably in one or more bearings 64 carried by a portion of the auxiliary frame 28. The idler shaft is provided with a pulley 65 for driving the drawing roll 48 through the belt 5I and also carries a cam 61 engaging a yoke 68 formed in one end of a lever 10, the lever 10 being pivotally supported, as at 1I, from a portion of the auxiliary frame 28. The opposite end of the lever 10 is pivotally connected, as at 12, with a link 13 for oscillating a traversing guide arm 14 which is supported by the auxiliary frame 28, as at 15, and provided with guide means 16 for laying the wire I0 upon the spool 54.

In the operation of the mechanism above described, the wire I0 from the spool 8 is drawn over the guide pulley 9 into the opening II of the tubular member 4 and upwardly through the restricted opening in the guide plate I2 from which it passes through the restricted opening in the guide plate 44 and upwardly through the tubular guide member 42 to pass over the guide pulley 46. From that point the wire I0 is passed downwardly into the receptacle 31 and under the rolls 48, and then upwardly over the drawing roll v48 and then through the guide means 16 carried lby the traversing guide arm 14 for laying it upon vthe spool 54 as the spool is rotated through its driving connections from the drawing rolls 48. In passing from the guide block I2 to the guide block 44 a plurality of strands or filaments I8 are applied to the surface of the wire IIJ in the form of spiral windings, which are preferably applied in superposed layers through the dierent heights of the guides I1. That is, it may be found desirable to employ iilaments of different materials for the different layers of spiral windings, as, for example, the rst winding to be applied to the wire may consist of a rubber thread taken from one of the carriers I6 and passed through the lowest of the several guides I1, the next lament to be applied may be a silk thread from one of the carriers I6 passed through the next highest of the guides I1. The remaining threads or filaments to be applied, whether one or more in number, may be of cotton, jute or other fibrous material, or even of the same material as that of the second filament applied, are taken from the remaining carrier or carriers employed and passed through a guide or guides I1 of progressively greater height than those previously mentioned in such a manner that each successive thread or filament is directed into Contact with the wire at a point above the thread next adjacent thereto. In this way, each thread or lament is applied as a separate spiral winding to form a surface covering of substantially uniform diameter throughout its extent. By reason of their different points of application each thread or filament is applied independently of the others, since those applied at the lower heights from the surface of the table I4 are complete in their spiral application before those applied from higher points are formed on the upwardly moving Wire.

Thus, for example, the rubber thread mentioned as rst applied, forms a spiral layer directly on the wire, the silk thread next applied forms a spiral winding over the previously applied rubber thread, and the cotton, or vother threads, in one or more layers are each superposed on the layer last before applied. In this way, a plurality of spiral windings may be built up as superposed layers on the wire, each of the later applications tending to assist in holding the initial layers rmly in position on the wire.

After the application of the various layers of wound material, the Wire I passes upwardly through the tubular guide member 42 and over the pulley 46, then down through the receptacle 31 where the layers of applied material are subjected to impregnation or partial impregnation by wax or other binding material 39 contained in the receptacle.

wound wire tends to compact and amalgamate the coverings, and by the use of a binder of a suitable character, not only binds the applied layers together, but may increase substantially the insulating qualities of the applied coating.

'Through operation of the mechanism above described a definite and substantially xed quality of the wire coating may be obtained, wherein the coating may comprise layers of different materials superposed one upon the other in any desired order of radial arrangement, and wherein the materials applied may possess different wear resistant and insulating qualities but so arranged in the order of their application as to best protect the wire from abrasion and at the saine time give it maximum insulation.

In driving the winding spool 54 from the drawing roll 48 a tension means of a suitable character may be positioned between the drawing roll 48 and the spool 54 to apply such tension to the wire as may be desirable for laying it evenly on the surface of the spool, which tension means may be suitably positioned on the guide arm` 14, such as by association with the guide means 16.

While I have shown the several parts as driven by pulleys and connecting belts for operating the mechanism, it will be understood that suitable gears and gear trains may be substituted therefor with such suitable shaft connections as may be desired for operatively interconnecting the operating parts for drivingthe same from the motor or other power source.
