Specification of Letters Patent.

Patented July 14,1908.

Application filed January 8, 1908. Serial No. 409,771.

To all whom it may concern:

Be it known that I, SAMUEL J. SILL, a citizen of the United States, and a resident of the city of Buffalo, county of Erie, and State of New York, have invented an Improved Machine for Removing Wrappers from Hose after the Vulcanizing Operation and for Rewinding said Wrappers on Man drels, of which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this speclfication.

In the manufacture of sections of rubber hose, such as are commonly employed in railway air brake systems, (these sections be ing usually about 22 inches long), it is customary to wrap the hose, prior to' the vulcanizing operation, with wet cloths or rags which serve to insure the uniform distribution of the soft rubber cover of the hose until it has been set by the vulcanizing process. After the hose and the vulcanizing mandrel whereon it is mounted have been withdrawn from the vulcanizer, the wrappers or rags are removed from the hose and are soaked or wet with water ready for subsequent use.

The present invention has for its object to provide an improved machine for removing the wrappers or rags from the hose after the vulcanizing operation and for wetting and rewinding these rags or wrappers on a mandrel so that they may be conveniently used thereafter for the straight wrapping of' other sections of unvalcanized hose.

The invention consists in the features of novelty hereinafter described, illustrated in the accompanying drawings and particularly pointed out in the claims at the end of this specification.

In the drawings, Figure 1 is a plan view of the improved machine. Fig. 2 is a front elevation thereof. Fig. 3 is a cross section. Fig. 4 is a detail section.

1 designates the bed-plate of the machine that is mounted upon suitable legs or supports 2. The central portion of the bedplate 1 is cut away, as shown, and beneath this cut-away space is held a-tank or pan 4 from end to end of which extends a perforated ipe 5 through which water will be admitte through a suitable supply pipe 6. I

An outlet pipe 7 connects with the tank 5 to conduct water therefrom.

From the top of the bed-plate 1 rise the brackets 10 and 11 that carry the centering rods 12 and 13, these rods having coneshaped ends 14 to enter and center the ends of the hose-carrying, vulcanizing mandrels from which the wrappers or rags are to be unwound. The centering rod 13 is shown as screw-threaded to pass through a corresponding threaded opening in the standard 11 and the outer end of this rod 13 is provided with ahand-wheel whereby it may be adjusted. The heads 14 are rotatably secured to the rods 12 and 13 by pins 14 (see Fig. 4). The rod 12 is mounted in manner free to slide through the opening in its bracket or support 10 and to the outer end of the rod 12 is pivotally connected as at 15 a lever 16 whereby the rod 12 may be shifted. One end of the lever 16 is pivoted as at 17 to a bracket 18 that is bolted to the bed-plate 1, and, adjacent the opposite end of this lever 16 is connected a cord 20 that extends over a pulley 21 and has connected to its lower end a weight 2-2, the weight 22 serving to draw inwardly the lever 16 so as to press inward the rod 12 and thus hold the vulcanizing mandrel upon the centers 14 whereon it will revolve as the wrappers or rags are wound therefrom. The pulley 21 is mounted on a bracket 23 that is bolted to the front of the bed-plate, the upper end of this bracket having a laterally extended rest 23 for the outer end of lever 16 and a stop 23 to limit its movement. When a vulcanizing mandrel has been placed between the centers 14 at the inner ends of rods 12 and 13, the weight 20 will cause the lever 16 to force inward the rod 12, thereby insuring the active engagement of the rotatable centers 14 with the open ends of the vulcanizing mandrel.

Upon the top of the bed-plate and the opposite ends of the chamber or tank 4 are mounted the bearing-blocks 30 in which will be revolubly supported the mandrel 31 (in dicated by dotted lines, Fig. 1), whereon each wrapper or rag will be wound after it has been withdrawn from the vulcanizing mandrel and has been wet with water, as will presently appear. 'Suitable caps 32 will set over the ends of the mandrel 31, these caps being detachably connected so that the mandrel can be removed from the machine after a sufficient number of wrappers or rags have been wound thereon. ing-blocks 30 are formed with perforated,

' tain the cap securely in position.

offset lugs orflanges 35 at their opposite sides, and each of the caps 32 is shownas provided at one side with a depending, perforated arm 36 through which will pass a bolt 37 that pivotally connects the cap to the bearing-' block 30. At its opposite side each cap is formed with a slot 38 through which will pass a bolt 39 that is pivoted as at bolt 40 to the bolt that passes through the lugs at the front of the corresponding bearing-blocks 30, and this bolt 39 has a screw-threaded upper end to receive a wing nut 41 which, when the bolt is slipped within the slot 38 will serve to re- When, however, it is desired to remove the mandrel after a sufficient quantity of wrappers or rags have been wound thereon, the o erator will loosen the wing nut 41 and swing 'orward the bolt so as to permit the caps 32 to be turned backward in order that the filled mandrel may be withdrawn. At one end of the bedplate and at a point adjacent one of the bearing-blooks for the rewinding mandrel, is placed a journal standard 01' bearing wherein is mounted one end of a drive pulley shaft 51, the outer end of this shaft 51 being journaled in a suitable bearing boX 52 mounted at the upper end of the curved bracket 53 that is bolted as at 54 to the end of the machine. The inner end of the drive pulley shaft 51 inside the bearing boX 50 is provided with an enlargement 55 and a suitable cap or collar 55 will be mounted upon the outer end of the shaft outside the bearing 52 to hold the same against endwise movement. Upon the shaft 51 is revolubly mounted the drive pulley 56 having friction faces at its opposite sides and upon the shaft 51 at the oposite sides of the pulley 56 are splined friction clutch disks or members 57 and 58. The friction disk or member 57 has an annular groove 59 formed in its hub, and into this groove 59 will project pins 59 on the bowed portions of a clutch lever 60 whereby the friction disk 57 will be moved into and out of engagement with the drive pulley 56. The clutch lever 60 is pivotally mounted as at 61 upon a bracket 62 projecting from the end of the machine. The en largement on the inner end of the shaft 51 inside the journal bearing block 50 is provided with a chamber or cavity 64 to receive one end of the mandrel whereon the wrappers or rags will be wound. As shown, a pin 65 projects into the chamber 64 to engage with the end of the mandrel whereonthe wrappers or rags will be wound as they are drawn from the vulcanizing mandrel.

As shown, there are two boards and 71 on the top of the bedlate 1 and to these boards are hinged the p ates or covers 73 and 74 the under faces of both of which will be covered with zinc. In operation, the wrap ers from the tube section are passed down 1nto the tank below the perforated pipe 5 and then over the mandrel 31, as indicated in dotted lines in Fig. 3. Mandrel 31 is then driven from shaft 51 to unwind the wrappers from the tube and wind them up on the mandrel 31 when the friction clutch is thrown into operation. At the same time the wrappers are soaked for reuse. The plate 73 not only serves to prevent the water from splashing over onto the floor, but, as it is provided with spring hinges 72 it also serves to place a certain amount of friction on thewrapper carried by the hose so as to prevent a too loose unwinding of the wrappers from the hose. The front board or plate 74 also prevents the splashing of water in forward direction and is adapted to bear on the surface of the wrappers or rags as they are being wound upon the rewinding mandrel, thereby preventing wrinkles being formed in the wrappers. This is an important feature since, when the wrappers or rags are taken from the rewinding mandrel and wound upon the hose preparatory to the vulcanizing operation, it is essential that the wrap er shall be laid around the hose uniform y without wrinkling, in order to prevent the marring of the outer cover of the wrap er which becomes softened during the vu canizing process and would, therefore, take the impression of any creases or wrinkles in the wrappers.

It is obvious that changes may be made in the details set forth without departure from the essentials of the invention.

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