JOHN J'.-REINHOLD, 0F MARIETTA, PENNSYLVANIA.

INSULATING MACHINE.

Application filed November 25, 1921.

To LIZ whom t may concern.'

Be 1t known that I, JOHN J. REiNi-IOLD, a

citizen of the United States, and a resident 1 of Marietta, county of Lancaster, State of Pennsylvania, have invented certain new and useful Improvements in Insulating Ma chines, of which the following is a specilication.

This invention relates to a machine for applying ibrous'material to Wires or rods.

This invention relates more Ispecifically to the art of insulating., electrical conductors with asbestos in which 4the general process consists: first of coating the wire with an adhesive, next applying the insulating material, then of saturating or impregnating the insulationwith a. dielectric or binding material, and then rolling or compressing the insulation to a uniform size.

The object of this invention is to provide a device which will apply fiocculent fibrous materials to a. constantly progressing Wire,

and completely cover the *same at uniform' thickness, or more particularly to provide a carding device through which the fibrous materia-l is formed into a strip which contains an exceptionally funiform quantity of fibers per unit of length.

In the following description I will refer to the drawing, 'in which similar numerals refer to similar parts throughout the several views.

Fig. 1, represents an end elevation of the device for applying the insulating material to the wire and embodies the principal fea tures of this invention.

Fig. 2, is a sectional View of Fig. 1 t-aken on line 2-2.

Fig. 3, is a sectional View taken on line 3-3 of Fig. 1. p

Fig. 4, is a sectional 4 4 of Fig. 1.

Fig. 5, is a diagramma-tic View of a carding machine including the mechanism shown in F ig. 1.

Fig. 6, is a diagrammatic view of aV complete insulating machine embodying the mechanism shown in Fig. 1.

Fig. 7, is a modification of the device shown in Fig. 1. r

In the drawing, 1 represents a coil of bare wire carried by the swift 74 which is free to rotate on the veitical spindle 75. The wire 5, leading from the coil 1 passes over the pulleys 6 and 7, under the pulley 8, over the view taken on line serial No. 517,726.

pulley 9, through the covering device 10, over the pfulley 11, under pulley 12, over pulley 4, between pressure rollers 15, through spraylng device 16, around the pull-out wheel 17 severa-l times, and is finally wound upon the reel 18 in finished condition.

The Wire 5 when passing under the pulley 8 is submerged :in Van adhesive bath 19 and is thereby given a coating of adhesive material.

The device indicated at 10 is a diagrammatic View of the mechanism shown in detail in Figs. l and 2 and serves the purpose of applying a fibrous covering to the wire 5 as hereinafter described.

The pull-out wheel pulls the wire 5 through the machine at a. uniform speed in the direction indicated by the arrow 22 and feeds it to the reel 18.

The main drive shaft source of motive power through the 'pulley 24. The covering device 10 is caused to op-' crate from the main drive shaft 23 through the sprocket 25 and chain 26.

The pull-out wheel 17 is caused to rot-ate from the main drive shaft 23 through the Worm 26, worm gear 27, shaft 28, pulley 29, belt 30, pulley 31, and'shaft 32.

The reelv18 is caused to rotate from the shaft 28 through pulley 33, belt 34, pulley 35, and shaft 36.

Journalled in the bracket 37 is a hollow spindle 38, to which is fixed the disk 39 and gear 40 through the keys 41 and 42 respectively. Carried by the spindle 38, in a manner flee to rotate relative thereto, is a hub 43 forming a part of the gears 44 and 45.

J ournaled in the bracket 37 is` a shaft 46, to which is fixed the gears 47 and 48 and sprocket 49, through the keys 50, 84 and 85 respectively. The gear 47 meshes with the gear 40 and the gear 48 with the gear 44 as shown.

23 is driven by any The speed ratio of the gears 47 and 40` is different from the speed ratio of the gears 48 and 44; therefore when this mechanism is caused to operate, the gears 44 and 45 will rotate relative to the spindle 38: or in other words they will rotate at a different speed relative to said spindle. y

Journaled in the disk 39 is a shaft 51 to which is fixed the gear 52 and the pulley 53 through the keys 54-and 55 respectively.

Adjustably mounted to the disk 39 through the bolt 56,

sleeve 57 'and the slot7 Il' 58, is a gear 59 which is adapted to mesh ,with the gears 45 and 52. y

For simplicity in Fig. 1, the teeth ofthe gears 44, 45, 48, 52, and 59 are represented by light broken lines and the theoretical pitch circle; the gears 40 and 47 are not shown in this figure.

Carried by the disk which is mounted free Forming part of the fiange 6l.

An endless belt of card clothing indicated at 62 is adapted to run over the flange 61 and pulleys 53 and 60, the outside surface of which forms a true arc with the center of the spindle 38 to the extent indicated by the arrow 63; the surface extent of the card clothing belt indicated by the arrow 64 forms a straight line which passes in close proximity to the axis of rotation of the disk 39.

The diagrammatic view of the carding machine shown in Fig. 5, represents the principal elements thereof; the main cylinder being indicated by 65. The functions of the carding machine elements are well understood by those experienced in the art and need not to be described here, however, the substitution of the device indicated by l0 for the usual type of dotfer employed 1n carding machines does not change the functions of the remaining carding machine elements or their mode of operation.

The operation of this device is as follows:

As the mechanism shown in Figs. l and 2 is caused to operate through the chain 26, it is apparent that the pulley 53 will be caused to rotate through the shaft 51, gears 52 and 59, and the movement of the gear 45 relative to the disk 39 as heretofore described; and it will carry with it the endless card clothing belt 62, thereby ultimately bringing all points of the surface of the card clothing belt alternately within the regions indicated by the arrows 63 and 64..

The carding machine is set in operation and the fibers from the main cylinder 65 are picked up by the teeth on the endless card clothing belt 62 over the surface portion within the limits indicated by the arrow 63. The fibrous material is removed from the belt 62 when it reaches the wire 5, to which it adheres, and is wound around the same through the rotating action of the disk 39 and the belt 62.

In one revolution of the disk 39, the card clothing belt 62 advances a distance substantially equal to the circumference of the wire 5. The distance indicated by the arrow 63 on the card clothing belt may be equal to many times the circumference of the wire, therefore every point on the card clothing belt 62 passes the main cylinder a niimbcr of times` between each time it passes the wire 5. It is to be. observed that fibrous material 39 is a stud 73 upon to rotate, a pulley 60. disk 39 is a circular will be applied to every point of the card clothing belt a number of times to the once taking off. This has an equalizing efi'ect in the formation of the fibrous .strip built up 0n`the belt, because it is built up of a series of very thin layers, the inequalities of each blending to produce an exceptional uniform thickness.

For certain kinds f fibrous materials it may be deemed advisable to subject the same toa certain amount of carding after it has been transferred from the main cylinder 65 to the endless card clothing belt 62; this may be accomplished with the device shown in Fig. 7.

This device is the same as that shown in Figs. l, 2, 3 and 4 in every respect except that the pulley 6() is mounted to the disk 39 at a location whereby the fibrous material will not pass directly from the card clothing belt 62 to the wire 5; this is apparent by observing the space between the ends of the teeth of the card clothing belt 62 and the wire 5 as shown at 77 and in additionto this feature a wheel 78 covered with card clothing 79 is mounted free to rotate on the stud 8O which is carried by the disk 39.

The wheel 78 is driven from the pulley 53, which has mounted on the side thereof a pulley 81; the wheel 78 is also provided with a pulley 82 which forms a part thereof, and a cross belt 83 is adapted to transmit motion from one to the other.

The operation of this device is that the fibrous material, instead of passing directly from the card clothing belt 62 to the wire 5, is taken up by the card clothing 79 on the wheel 7 8 and from there is wound around the wire 5.

This device must be so constructed that the peripheral speed of the card clothing belt 62 is slightly greater than the peripheral speed of the card clothing 79, so that the fibrous material will transfer from one to the other.

It is obvious that the wire. 5 might be 'square or hcxagon shaped, or rectangular, or in ribbon form, instead of round as shown, and the device shown in Figs. l and 2 will operate and cover the wire in the same manner as herein described.

Having thus described my invention, what I claim, and desire to secure by United States Letters Patent, is as follows:

1. The combination with a frame structure rotatably mounted, of an endless belt having teeth and carried by said frame structure, 'said endless belt being so arranged that a portion only thereof forms a trueI arc concentric with the center of rotation of said frame structure, and propelling means arranged to progressively move said endless belt when said frame structure is rotated.
