reasons.

To all whom it may concern: p

Be. it. known that I, RAY-P; JAoKsoN, a citizenof the United States, and a resident of hdgewood Park, in the countyof Allegheny and State of Pennsylvania, have 1nvented a new and useful Improvement in lVire-Covering Machines, of which the fol: lowing is a specification. a Y

My invention relates to machines for covering wires, cords and the like with fibrous material, and it has for its object to provlde amachine of the character indicated which shall be simple in construction, efficient 1n operation and capable of rapidly handling sliversof cotton, asbestos and the like which have but little tensile strength.

More particularly, theobject of my invention is to provide a wire-covering machine in which a sliver, cordor othersimilar body of fibrous material is drawnfrom a bobbin or othersource of supply, conveyed to the wire to be covered by means of a suction conveyer and detached from the conveyer and directedtoward'the wire by means of an air blower, the arrangement of parts being such: that the sliver is rapidly drawn from :the bobbin and applied to the wire without being subjected to suflicient longitudinal pull to break it. i e

1 1n the accompanying drawings, Figure 1 is a plan view of a machine constructed in accordance with my: invention. Fig. 2 is a central longitudinal sectional view, with parts shown inelevation, of the machine shown in Fig.1, the section beingtaken substantially :along the'line II-.II of Fig.1, and Fig. 3is axside elevational View of a portion of .the apparatusrshownin Fig. 1.

In the machine shown in the drawings, a

round sliverl isdrawn from a coiled. sup- .ply 2 by means of cooperating feed rollers 3 and Land delivered to a rotary suction conveyer 5 which carries the sliver to a point adjacent to a longitudinally advancing wire 6,'where thesuction is interrupted, the sliver being detached from the conveyer 5 and directed toward the wire by means cf a pressure device of air blower, the nozzle of which is indicated at 7. The supply 0; sliver is mounted upon asuitablespool or other convenient support 10 which, together with the feed rollers 3 and 4,-the conveyer and the blower-nozzle 7, is mounted upon a rotatable sup ort: 11.- The end of the support 'llopposite to the sliverspool '10 is secured,

by means of screws 12, to a counterweight member 13 which is formed on, or secured to, a circular disk 14 that rests movably upon a stationary plate 15 disposed upon a su porting base 16. The disk 14 is provided with a central opening to receive a vertical sleeve 17 whichalso extends through a core responding circular opening in the plate 15 and is confined between the supporting member 11 and the base 16. By means of a suitable key 18, cooperating with the sleeve 17 and the plate 15, the sleeve is maintained stationary.

Suitable openings

19 and 20 are provided in the support 11 and the base'lti, respectively, in alinement with the internal portion of the sleeve 17, and the wire 6 passes through the opening 20, sleeve. 17 and opening 19 and is caused to move longitudinally by any suitable jmechanism (not shown), g

Forthe purpose of rotating the support 11, gear teeth 21 are formed in the periphery of the disk ll andare adapted to mesh with the teeth of a spur gearwheel22that is secured to the: vertical armature shaft 23 of a driving motor 24. c 1

The suctionconveyeroconsists of a ring spaced radial perforations 26. A ring 28 provided with openings 29 corresponding to 25, and a circular cover 30 incloses the rings 25 and 28 andforms a substantially vacuumtight chamber which is divided into: two parts and 36 by means of a stationary partition 37. The compartment 35 is maintained at subsatmospheric pressure while the compartment 36 is at normal pressure and contains the blower nozzle 7. As shownin Fig. 2, the blower nozzle rests upon thein ner surface of thering25 and blows air through the, openings 26 as they are successively presented'to it. i i

- The partition 37' is formed-integral with or attached to a standard 40which isrigidly secured, bymeansFof screws 41 or otherwise,

to the dislcll and also serves to support pipes 42 and l3 that are coupled together connected, at one end, to the chamber 35 of thersuction conveyer for the purpose of -maintaining reduced mpressure within this compartment. 1

.25 provided with a considerablenumber of i the radial openings 26, surrounds 'the ring Since the disk 14 revolves during the operation of the machine, it is necessary to provide means for permitting such revolution to take'place without disturbing the vacuum connection to the channel 44: or the r the plate 15, the opening 52 being adapted to cooperatewiththe circular channel 50 and the opening 53 being adapted to cotiperate with the circular channel 51. The opening 52 is connected, through a channel 511 and a pipe 55, to a suction pump or other suitable suction producing device, While the opening 53 is connected, by means of a channel 56 anda pipe 57, to a suitable source of compressed air. It will be readily understood that the arrangement of ports and channels just described permits the disk 1'4, with its associated apparatus, to revolve around its. central axis without disturbing the reduced pressure within the chamber of the suction conveyer or the supply of air under pressure to the blower nozzle 7.

The'ring 25 rests partly upon the support 11 and partly upon a circular frame 60 which is disposed in an opening in the support 11 and is rigidly secured to the ring 25. Resting upon an annular ledge 61 formed in the support 11 is a ring 62 which 005perates with the frame 60 to form a ball race in which'bearing balls 63 are disposed in suitable grooves.

For the purpose of effecting the rotation of the suction conveyer 5 while it is revolving bodily around the wire 6, a gear ring (it is secured to the frame 60 and is provided with teeth meshing with the teeth of a stationary pinion 65 that is secured to the vertical sleeve 17.

The feed rollers 3 and 1 are driven at a peripheral speed corresponding to the peripheral speed of the suction conveyer 5 by means of a train of gearing best shown in Figs. 1 and3. A bracket is secured to the support 11 by means of bolts 71 or otherwise, and supports bearings for a vertical stub shaft 7 2 that carries a spur gear wheel 7 3 to mesh with the teeth of the gear ring 64. The stub shaft. 72 carries a bevel gear wheel 74 to mesh with a bevel pinion 75 on a horizontal shaft which also carries a miter gear wheel 76' to mesh with a miter gear ,wheel 77, The miter gear wheel 77 is secured'to one end of a shaft 78 which carries the feed roller 4;. Y

. rial as well as to wires.

In order to limit the transverse movement of the sliver 1,, as itis drawn from the bobbin, a semi-circular guide 79 is provided adjacent to the feed roller 1.

In the operation of the machine, a supply of fibrous material in the form of a sliver or cord is placed upon the spool 10 and the end of the sliver or cord is carried through the guide 79, between the feed rollers 3 and 4- and around the periphery of the suction conveyer 5, as shown in Fig. 1, and is wrapped around the wire 6. The feed rollers 3 and a draw the sliver from the bobbin, and also flatten the sliver into a ribbon-like strip, as shown in the drawings. The pipes 55 and 57 are connected to the sources of suction and pressure, respectively, and the motor 24- is started. The disk 1% then rotates around the wire 6 carrying with it the suction conveyer and the supply of sliver. The gear ring 64:, rolling upon the stationary pinion 65, causes the suction conveyer to rotate with relation to the support 11 and, at the same time, supplies power for rotating the feed rollers 3 and 4. These movements of the conveyer and the feed rollers serve to draw the sliver from the spool 10 with a minimum of longitudinal pull.

It is obvious that numerous variations may be made in the structure which I have shown and described without exceeding the bounds of my invention, and that the machine is capable of applying coverings to straps, rods and other forms of strip mate- It is therefore to be understood that the term wire, in the appended claims, includes all such equivalent strip material, and that my invention comprehends all such changes and rearrangements as fall within the scope of the appended claims.

I claim as my invention:

1. A wire-covering machine comprising a suction conveyer for transferring covering material to the wire to be covered, and an air blower for detaching the said material from the said conveyer ad acent to the wire.
