ROLLING AYPARALUS.

Application filed'lv'iay 31,1923. senai' No. esaeea.

To all whom z't'maz concern;

Be it known that Knnivdirrrn' J. THOMP- so'v, subject of the King of Great'Britain, and a resident of the city of Mansfield, in the county' of Richland' and State of Ohio, have invented certain new and'useful Improvements in a Rolling'Apparatus; andI do hereby declare that'the .followin'gis a fulhclear, and exact description ofthesame, reference being had tothe accompanying hrawingsi andto the numerals 'of' reference marked tl1QIBQI1,W-hl0l1101'111 apart of this specification.

This invention relates to 'machines for compressing and rolling "strips 'of fabric and the like.

In the manufacture of tires two or more ply fabric is employed and hitherto this has been made by pressing together the strips of rubberized fabricby hand with or without the aid of manuallyope'rated tools.

It has been'found very difficult to expel all the air from between the strips'andbring the layers of fabric into 'closecontact With each other. This is necessary to prevent fabric separation during I'vulca niz-ation. Even a small air bubble will expand in the vulcanizing operationand prevent union of the "tWo layers over a much larger area than that originally occupied by the'bubblef One of'the'principal objects of the'present invention, therefore, is the provision of 'm'eans for pressing together two orfmore treated strips of-fabric so as to expelthe air therebetween. I

A further object of the invention 'is the provision of means for rolling anendless strip of fabric. 7

It is also an object of the invention to provide means for supporting ane-ndless band of fabric in extended position *and'simultaneously passing itfb'etxveen rolls.

An additional object of'the inventionis to provide a rolling machine, into which an endless band can be readilyinserted and as readily Withdrawn.

Other and further important objects of this invention Will be Y apparent fr'ojm the lisclosures in the specification and accom- -Figure 3 is a side elevation of themachine.

Fi gure 8 is an enlarged detailvieiv of the toggle mechanism for operating the tension roll.

Figure 9 i'sa view takenon-the line 9-9 of Figure 6.

As shown on the drawings: 'l-he machine -co-mpr1ses a base 10, from which, adj acent one corner, rises a standard 11. On one side of-this standardis secured or made integral therewith 'a frame 12.

In theuppe'r part of this frame is journaled a shaft carrying a roll 14, -Above this roll is asimilar 'roll' carried by a frame 16 pivotallyconnected to the main frameat -17. V

In view of the fact that the frame 16 is supported at one end only and the rolls 14 and 15 are=separable at their ends opposite to the frame support, endless strip of inaterial i nay readily be'inserted between or Withdrawn from the rolls.

The shaft '18, 'vvhichcarries the roll 15,

vis not journaled directly in the frame 16, but in bearings 19 having cylindrical extensions -20 which project into sockets in the frame 16. In these sockets are arranged springs 21 tencling to press'the roll 15 downwardly. The tension of these springs may be varied by mean's ofheaded bolts 22.

Instead ofusingsprings to provide the "desired downward pressure on the roll 15 fluid pressure, such as compressed air; may be employed. ThlS may convenientlyv be accomplished by lnsertlng compressed 2111' eonnections in place-0f the bolts 22 and placing piston rings on theezitensions 20.

The free end o'ffthe frame 16 is normally connected to the frame 12 by'nieans of a hook 23, rotatably secured to tlielovver frame *and adaptfed toengage *a'f 'pin 24- projecting fijonrthe e'nd efthe frame 16. V

- "When the hook =23 "is disengaged from the apivot notbnly as tlre-resnlt-ofthe action pei ijigs 2-1; ieh 'act o'n the roll 15, but

;p'i n%24,tlie rams-16 swings ipivardly about also by the action of springs provided for this purpose near the pivotal axis of the frame. Pins 28 are provided for limiting the downward movement of the roll 15 when the frame 16 is elevated.

The hook is rotatably mounted on an eccentric 26 secured to a shaft 27 journaled in the frame 12 so that by turning the shaft after the hook has been brought into engagement with the pin 2i, the upper frame n'iay be drawn downwardly. A handle 29 s curcd to the end of this shaft 2? enables it to be turned when desired.

On the strap around the eccentric 26, which carries the hook pins 60 may be arranged for engagement with the handle 29 so that the handle 29 cannot be brought into vertical position without causing the hook to engage the pin 2-l or into horizontal po sition without disengaging the book from the pin.

In addition to providing a pair of springpressed rolls, it is also desirable to provide means for holding the endless band of treated fabric in extended position while it is being passed through these rolls, and also to provide means for examining the band while under rolling treatment.

For this purpose brackets 30 are provided, extending forwardly from the frame 12 and between them extends a table 31. At the forward edge of this table a roll 32 is pivotally mounted. This table 31 is so arranged that its upper surface is in substantially the same plane as the line of contact of the rolls 1% and 15 and the upper surface of the roll 32.

On the other side of the frame 12 another roll 33 is provided, rotatably mounted on ashaft- 35 journaled between lugs 34:. A tension roll 36 is provided, journaled between arms 37 secured to the shaft By turning this shaft, therefore, the position of the tension roll may be varied. The mechanism for turning the shaft includes a sleeve 238 rotatably mounted on the shaft and provided at its outer end with a flange 39. The shaft 35 is provided with a similar flange. "f0. A bolt a1 attached to the flange 39 extends through an arcuate slot 42 in the flange e0. A. ring-nut serves to clamp the two flanges in any desired position.

()n the sleeve 38 is an arm if connected by links to an arm 46 attached to the shaft 27, which is rotatable by the handle 29. Hence, by operating the handle 29 the shaft 35 may be turned and the position of the tension roll varied.

The machine is intended for use on annular bands of various diameters. and in changing from one size to another'size it is desirable to provide quick means for adjusting the rerativc positions of the flanges 39 and d0 so that when the handle 29 is brought into its upper position the tension roll is swung downwardly to the requisite extent,

For this purpose I may provide a series oi steel bands having diameters equal to the band to be pressed.

To set the machine by one of these bands 61 the wing-nut $3 is loosened so that the flanges 39 and a0 are free to move relatively to each other. The handl 29 is placed in vertical position and the band (31 is placed around the rolls as shown in Figure The tension roll 30 is then depressed mull the band (31 is drawn tight. The wing-nut is then tightened to lock the flanges 35) and it) together.

The handle 29 is thenswung downwardly to raise the tension roll to allow the steel band (51 to be removed and the fabric band to be inserted in its place.

In place of, or in addition to, the use of steel bands of known diameter, a scale 62 may be provided behind one of the arms '57 which carries the tension roll 36. This scale may he graduated arbitrarily for use with a computing table or itmay he graduated so as to give directly the circumference or di ameter of a steel tape which, when stretched. will encircle the rolls with the tension roll ll; in that position.

It will be seen from Figure 8 that when the tension roll is extended downwardly the arm 1-6 and links are in substantially a straight line so that we have a toggle joint connection.

Ylhile, in view of this toggle connection. direct pressure on the tension roll cannot turn the shafts 35 or 2]", the parts might, unless otherwise prevented, become displaced by vibratory movements. To hold tl e handle releasably in the desired position, a bolt 41-? is slidably mounted on the handle 20. This bolt is provided with a rounded end 45: adapted to enter an aperture in the upper frame 16. A. knob 49 at its other end enables the bolt to be withdrawn manually against the action of its spring .70.

The lower roll if only rotated by power. and for this purpose a pulley .71 is rotatably mounted upon the shaft 1 3, which carries this roll. A clutch serves to connect the pulley to the shaft when desired. This clutch is operated by a bell crank 53. one arm of which is forked for engagement with a pin 54 on the clutch. The other arm of the liiell-crank is connected by a link 55 to a pedal 56.

The operation is as follows:

The handle 29 is swung downwardly, and by engagement with one of the pins it) the book 23 is simultaneously disconne ted from pin 2-1:. The springs tend to more the frame upwardly so as to separate the roll- 1-1- and 15 and allow the endless band to be inserted therebetwccn. The down 'ardmovcment of the handle 29, by means of shaft 2?, arm 46, link l5, arm 1 shaft 35 and arms 37, causes the tension roll 36 to be loo engage the pin 24. This hook is preferably moved into enga ement by hand, but may be forced into engagement with its pin by pressure of the handle against the pin on the strap portion of the hook.

The machine is then set in operation by n'essin down the oedal 56 which 0 oerates' to l 7 the clutch between the pulley 51 and the shaft 13, which carries the roll 14:. c

I am aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and l thereforev do not purpose limiting the patent granted other-- wise than necessitated by the prior art.
