Jim M ATTORNEY.

STOCK RACK.

' Application filed November 19, 1923. Serial No. 675,649.

.7 '0 all whom it may concern.

Be it known that I, THOMAS P. LITTLE, a citizen of the United States,

ing at Chicopee Falls, in the county of I- ampden and State ofhlassachusetts, have invented certain new and useful Improvements in a Stock Rack, of which the following is a specification.

' his invention relates to improvements in an apparatus for presenting to the tire builder uncured rub er stock or rubberized fabric that is sticky r tacky.

he object of this invention is to'provide a new and improved means whereby rubber stock, that has been spooled or wound up with a separate lining or web of muslin or other cloth interposed between the successive windings on the spool, may be straightened and presented to thetire builder in a vertical position.

The invention consists in the features of construction, combination. and arrangement of parts, hereinafter fully described and claimed, reference being had to t e accom: panying drawings,,in which ig. 1 is a perspective view showing the apparatus used in carrying out my tion;

Fig. 2 is a perspective showing the opposite side of the apparatus shown in Fig. 1;

Fig. 3 is a view showing the straightening or centralizing apparatus;- and Fig; 4 is a view of the supporting bar 100 'ng means- The frame 10 which carries the supporting brackets 11', 19. and 21 is mounted on the horizontal members 12 vertical position by bracing members 13.

The stock spool 14 is detachably supported at one end by a freely rotatable shaft 15 while the rotation of the,spool 14 is controlled by the crank 16. ratchet 17 and pawl 18. The shaft 15 is journaled in bracket 19 on frame 10 and has a shoulder preventing outward movement and is held against inward movement by the ratchet 17. The

inner end of the shaft has a central squared a square bar recess to receive the end of which supports the stock spool. I The other end 20 of the bar is 'turned,. to fit in the U shapedbearing 21 in frame 10, so as to provide a shoulder to prevent outward movement of the bar. r A pin 22 pivoted in bracket 21 is shown f holding the end 20 of the square supporting i of America, 2

27 so it can invenand held in the t bar in position by means of a knob 23 which slides on the outer endof the pin. A spring he outer endof pin 22 holds the mob 23 in its normal position. In changing ofrolls, the knob enough to clear a boss 25 on bracket 21 and swung up away from the end 20 of the supporting bar. The turned end 20 is first removed from bearing 21 and then the square end of the bar withdrawn from the central squared recess in shaft 15. In putting in'a new roll versed. The liner porting mechanism stock spool.

At the top and bottom of frame 10 are rolls 26, 27 sup orted by brackets 11. Mounted on the ame between the feed roll 14 and roll 26 is a curved bar 28 for the purpose of straightening and removing all wrinkles in the rubber stock and the liner, and also centering the liner on rolls 26, be wound up on the wind up the operations are rewind up roll and sup- Is the same as for the roll 29. 1

With a roll of rubber stock 30 placed in' position, the lineris unrolled and carried up overthe centralizing bar 28 to the roll 26. then down around roll 27 to the wind up roll29. By means of the crank 16 the liner 31 maybe wound on the liner roll 29 as fast as the rubber stock 30 is used.

Ratchets-17 and 32 and pawls 18 and 33 are used to prevent the stock roll and liner wind up roll from unwinding when the rubber stock 30 is taken off the liner. By raising pawl 18 off the feed roll ratchet 17 and 'urning the crank 16, the rubber stock on the liner may be brought into a vertical position between rolls 26 and 27.

e workman having the rubber stock be-. fore him in a vertical position (Fig. 1), he stands in front of the apparatus and with his hands pulls the lower end 35 away from the liner, placing it over his shoulder, and continues pulling the stock away from the liner until he has and then severe it. The workman is better able to judge the length of stock he needs by having it in a vertical position.

Having thus described my invention, I claim:

1. A vertical unwinding device, compris-. ing in combination a frame; supply and liner wind up rolls rotat'ably fixed at one side of the frame, two rotatable rolls 23 is pulled down mounted on the frame and located so as to guide the liner in a substantially vertical position at the other side of the frame during a portion of its travel from the supply roll to the wind up roll, means for unwinding the liner from the supply spool and rewinding it on the wind up spool, and means for preventing rotation of the supply roll and the liner wind up roll so as to hold the V liner stationary and taut when it is desired to remove the rubber stock from the vertioally extending part of the liner.

2. An unwinding device comprising a frame, supply and liner wind up rolls rotatably fixed at one side of the frame, two rotatable rolls mounted near the top and to the wind up roll,

bottom of the frame so as to guide the liner in its travel from the supply roll to the wind up roll, in a substantially vertical position at the other side of the frame during
