JAMES MUNTON, OF MAY\VOOD, ILLINOIS.

TIRE-ROLLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 401,? 13, dated April 16, 1889.

Application filed September 17, 1888. Serial No. 285,565. (No model.)

To all whom it may concern:

Be it known that I, JAMES MUNTON, a citizen of the United States, residing in Maywood, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Tire-Rolling Machines, of which the following is a specification.

My invention relates to improvements in the manufacture of tires from blooms, as set forth and described in Letters Patent of the United States, Nos. 363,842 and 363,843, granted to me May 31, 1887, and No. 381,505, granted to me April 17,1888. As described in said patents, after the annular bloom is cast, its top portion is sheared or cut oif by revolving rolls having cutter flanges or collars, and then the sheared bloom is edged in, densitied, and rolled to the required diameter by a rollingmachine having vertical and horizontal rolls to operate upon all four faces of the bloom or tire either simultaneously or consecutively.

My present invention consists in combining with the shearing or cutting rolls a stop or device to limit the approach of the cuttingrolls toward each other, so that the cuttertlanges of the rolls may come suiiiciently close together to sever the annulus from the bloom, and at the same time prevent the cutters from injuring each other by being forced 'together so that they strike or touch.

It also consists in combining with the ver tical cutter-rolls a pair of horizontal edgingrolls, which may be brought into play the moment the shearing or cutting operation is completed and the severed annulus removed, so that in this way, without removing the bloom from the mill or machine containing the cutter-rolls, the rolling operation and densification of the bloom may be continued as long as the bloom retains sufficient heat. lVhen the cutting operation is completed,the cutting-flanges of the cutter-rolls span or almost span the horizontal thickness of the bloom, so that no more rolling can then be done by the cutter-rolls without causing the opposing cutter-flanges to meet or strike against each other; but by combining in the same mill with the vertical cutter-rolls a pair of horizontal edging-rolls the rolling and den sification of the bloom may be indefinitely continued at the same heat that the cutting is done, as the first effect of the horizontal or edging rolls which bear against the top and bottom faces of the bloom is to diminish the vertical thickness of the bloom and to increase its horizontal thickness; and as soon as the horizontal thickness has thus been increased sufficiently to prevent the opposing flanges of the cut-termolls from meeting the cutter-rolls may be again broughtinto play and operated simultaneously, or, if desired, alternately, with the edging-rolls.

It also consists in combining with the cutter-rolls and edging-rolls two exterior pressure-rolls, which tend in their operation to density the bloom and roll the bloom backward or to a smaller diameter, or to hold it at a fixed diameter under the action of the edging and cutter rolls. These two exterior pressure-rolls operate in conjunction with the exterior cutter-rolls. By this combination of the edging-rolls and the exterior rolls with'the cutter-rolls the rolling and densification of the bloom maybe continued to any desired extent at the same heat with the cutting operation, and a bloom or tire may thus be produced of much superior density, quality, and texture to the ordinary hammered bloom, as the fraying and injurious eitects of hammering are entirely avoided.

My invention also consists in mounting the inside vertical pressure-roll or its shaft on a separate slide from that which carries either or both of the edging-rolls, so that the downward or vertical pressure which operates the movable edging-roll will not increase the friction of the horizontal slide which carries the inside vertical pressure or cutter roll in cases where the edging and rolling operations are being carried on simultaneously.

My invention also consists in mounting the two horizontal edging-rolls and the hydraulic cylinder for operating the movable or pressure edging-roll inthe same horizontally-sliding frame upon which the two exterior pressure-rolls are carried, so that downward or vertical pressure upon or between the edgingrolls will not increase the friction of the horizontally-sliding frame when the edging-rolls and the exterior pressure-rolls are brought to bear simultaneously upon the tire, as is sometimes desirable.

My invention also consists in the novel devices and novel combinations of parts and devices herein shown and described, and more particularly pointed out in the claims.

I11 the accompanying drawings,which form a part of this specification, and in which similar letters of reference indicate like parts, Figure 1 is a side elevation of a machine or mill embodying my invention. Fig. 2 is a plan view. Fig. 3 is an end view. Fig. 4c is a vertical longitudinal section. Fig. 5 is a cross-section on line 5 5 of Fig. 2. Figs. 6 and 7 are cross-sections on lines 6 (i and 7 7 of Fig. 2. Fig. 8 is a detail plan view. Figs. 9 and 10 are cross-sections of the tire, showing its form after the shearing operation is completed and after being operated upon by the edging-rolls, respectively, and illustrating the action of the edging-rolls to increase the horizontal thickness of the tire, so that the flanges of the cutting-rolls will not meet. Fig. 11 is a vertical section showing ordinary box-rolls, which may be substituted for the cutter-rolls when the mill is being used for rolling or finishing tires or rings.

In the drawings, A represents the frame or bed of the machine; B and B, the cutter-rolls; O C, the two exterior pressure-rolls, and D D the horizontal or edging rolls.

The cutter-rolls B B are preferably both furnished with cutter-flanges or bevel-collars Z) I), the combined width of the flanges b b be ing equal to the horizontal thickness of the bloom when the cutting operation is completed. The shaft B of the exterior cutterroll, B, is journaled in stationary bearings B on the main driving-frame A, and it is driven from the main driving-shaft E through the bevel-gears l and E Its lower end is supported in a vertically and longitudinally adjustable cup-shaped box or hearing, B, the adjustment of which is effected by the wedge B and the screws B and B The shaft B of the movable cutter-roll B is j ournaled in bearings B B on the horizontal slide or carriage F, which reciprocates on suitable guides, F, on. the main frame of the machine. The slide F is connected by rods or bars F with the piston F of the hydraulic cylinder F, by which said slide F is reciprocated to force the cutter-roll B against the bloom in opposition to the roll B.

The movement of the movable or pressure roll B is limited by an adjustable stop, f, so that the cutter-flanges b b of the rolls B B may approach sufficiently near to sever the top portion or annulus of the bloom and still not quite meet and thus injure each other. This stop f preferably consists of a screw threaded in the barf which is secured to the frame A by the rods f f' The screw is furnished with a hand-wheel, f for turning it, and with a jam-nut, f

The rolls 0 C and the edging-rolls D D are preferably all carried by or mounted upon the same slide or carriage, G. The slide G is reciprocated in suitable guides, G, on the main frame of the machine by a hydraulic cylinder, G the piston G of which is connected to said slide. The vertical rolls 0 C and the horizontal roll D are all three journaled directly on the slide G; but the vertically-movable horizontal roll D is journaled in suit able bearings, D on a vertically-reciprocating supplemental slide, H, carried on the slide G.

The supplemental slide H is reciprocated (see Figs. at and 6) in its guides H on the sliding frame G by a hydraulic cylinder, H and piston H the stem H of the piston being connected to the slide H. An adjustable stop, h, limits the vertical movement of the edging-roll D, so that the tire or bloom may be edged down to any desired width. This stop 71 preferably consists of a handwheel nut on a screw-threaded stein, 7L, secured to the piston H". As the two opposing horizontal or edging rolls D and D and the hydraulic cylinder H for forcing them together, are mounted upon or carried by the same main slide or carriage, G, the pressure of the rolls D and Dwill oppose and neutralize each other and not be exerted against the guides G of the slide G, nor in any way increase the friction or the force required to reciprocate said slide G on the main frame A.

The vertically non-movable edging-roll D is journaled in bearings D on the reciprocating slide or carriage G, and it is driven from the main driving-shaft E through the spurgears E E and shaft E, which shaft is connected to the shaft D of said roll D by a hollow shaft or sleeve, D, having a spline, (Z, to permit the reciprocating movement of the slide G and shaft D The bearings C C of the two vertical rolls 0 C are mounted adjustably on the slide G, Figs. 1 and 2, so that they may be'adjusted closer together or farther apart, as may be required in "rolling tires of different diameters. This adjustment is preferably effected by furnishing the slide G with slots 0, in which the bearings or boxes C fit-,the position of the boxes in the slots being adjusted by a series of thin blocks, plates, or wedges, 0, as indicated in Fig. 2.

K K, Fig. 2, are a pair of exterior guiderolls mounted on adjustable slides K K, which reciprocate on transverse guides 011 the main frame A. The positions of the guiderolls are adjusted by screws 7e 75, having sprocket-wheels k W, chains 76, and sprocket-wheels 70 70 on the shaft is, which is furnished with a hand-wheel, 7t, for turning it.

L L represent the pipes by which the water or fluid under pressure is admitted to the hydraulic cylinders F G and H from the pumps and accumulator customarily employed in tire-rolling mills for operating the pressure or movable rolls. Valves L control the admission or escape of the fluid-pressure as required.

The cutter-rolls B B are removably secured upon their shafts, so that they may be removed and replaced by others when worn or when required in rolling blooms or tires or rings of different sizes and cross-sections. The cutter-rolls B B may also be removed and replaced by ordinary box or other rollssuch, for example, as shown in Fig. 1lwhen it is desired to use the same mill for plain rolling as contradistinguished from cutting and rolling. 1

The shaft of the movable or pressure roll B and the shaft of the movable or pressure edging-roll D are not driven except by friction with the tire or bloom being rolled. In practice I have also not found it necessary to drive the vertical rolls 0 C except by friction with the tire.

In operation thebloom the top of which is to be cut off is first placed in the mill and the cutter-roll B forced up against it by the fluidpressure admitted int-o cylinder F As the cutting operation proceeds under the action of the cutter flanges or collars Z) l), the rolls B B also roll the bloom, increasing its diame ter and diminishing its horizontal thickness. After the cutting operation is completed the annulus severed from the bloom is removed with a crane, and then the slide G is advanced until the edgingrolls D D are brought astride of the bloom, when the pressure is admitted int-o the hydraulic cylinder H and edging-roll D forced down upon the tire, the pressure being relieved at this time upon the inside cutter-roll, B. After the edging operation is continued for a while the horizontal thickness of the tire will be thereby so increased, as indicated in Figs. 9 and 10, that the cutter-r0ll B may be again brought into play without causing the cutter-flanges to meet and injure each other. At the same time with the edging operation the exterior pressure-rolls, O C, may also be brought into play to further densify the metal.

By mounting the hydraulic cylinders F" and G at opposite ends of the machine the slides which carry the various movable or pressure rolls may be more conveniently operated. The connecting-rods F which connect the slide F with its operating-piston F pass astride of the stationary exterior roll, B, and its shaft.

hen the mill or machine is being used for plain rolling or finishing the bloom intoa tire, plain rolls being substituted for the cutter-rolls B B 011 the shafts B B the stop f is set so as to gage the horizontal thickness of the tire by limiting the movement of the inside pressure-roll toward the exterior stationary roll. This stop f thus serves a very useful and important function, especially,

where the inside pressureroll is operated by a hydraulic cylinder and piston, as contradis' tinguished from a screw. By means of this stop I am enabled to prevent any wavy irregularities in the horizontal thickn ess of the tire, which might otherwise be occasioned by the hydraulic or somewhat elastic pressure which forces the inside pressure-roll against the tire. By means of this stop f, in combination with the stop h, which limits the movement of the vertical pressure-roll, the vertical thickness and the longitudinal thickness both of the tire may be accurately gaged and limited, so that the finished tire may be made very uniform.
