METAL-ROLLING MACHINERY.

SPECIFICATION formingpart of Letters Patent N0. 611,608, dated October 4, 1898.

` Application filed January 28, 1898. Serial No. 668,246. (No model.)

To a/ZZ whom/ it may concer-lfb: v

Be it known that I, WILLIAM J. BRADLEY, of the city of Troy, county of Rensselaer, State of New York', have invented new and useful Improvements in Metal-Rolling Machinery, of which the following is a specifica-- tion.

My invention relates to metal-rolling machinery for shaping the bars of metal from which, when cut in cross-section, plates-are produced for connecting railroad-rails, such as are shown and described in Letters Patent No. 427 ,017, with my improvements more particularly relating to the mechanism shown and described in Letters Patent No. 481,697, for rolling the bars from which such connecting-plates are out, it being the object of my improvement to make the initiatory and finishing passes by which the V-form entrantgroove made longitudinally in the bar being rolled may be varied in measurement and form to adapt this entrant-groove formed in the bar when cut into sections to receive any one of the varied form of rail-base flanges in use and to adapt the roll parts forming the initiatory and finishing passes to be repaired By making the roll parts which form the initiatory and finishing passes detachable the parts forming the initiato ry pass may be given an area which will regulate the amount of metal per lineal foot to be contained in the finished bar, and by changing the tonguing part of the roll forming the 1inishing pass the form given to the entrantgroove of the bar being rolled will receive the base of the rail of which the tonguing part of the roll is the counterpart in cross-section.

Accompanying this specification to form a part of it there are two plates of drawings containing six figures illustrating the application of my improvementawith the same designation of parts by letter reference used in all of them.

Of the illustrations, Figure 1 is a view in side elevation of a train of rolls detached from their housings, and showing the grooved sleeve parts and the tonguing sleeve parts of the rolls forming the several passes in central vertical section. Fig. 2 is a central vertical section taken longitudinally through one of the cores or shafts of a train of rolls, shown as detached from its housings, with the roll parts forming the initiatory and finishing passes shown as made detachable, with the roll parts between the initiatory and finishing passes formed integrally with the core or shaft. Fig. 3 is an end view of the tonguing detachable roll part of the initiatory pass. Fig. 4. is an edge view of the tonguing roll part shown at Fig. S. Figs. 5 and 6 are sections of differing forms of tonguing. roll parts of the finishing pass, with only the tonguing parts of the roll parts shown.

The several parts of the mechanism thus illustrated are designated by letters of reference, and the functions ofthe parts are described as follows: Y,

The letters A designate the shafts or cores of the train, each of which is provided with journals A', arranged to be rotated in bearings in housings, which, being of the usual vwell-known form, are not shown.

The letters P, P', P2, P2, P4, P5, and P6 designate the successive passes of the train. The initial pass P is formed by sleeve parts upon the middle and lower shafts, the sleeve on the bottom shaft of the train being composed of the two sleeve-sections S and S and on the middleshaft o f the two sleeve-sections S2 and S2, with the outer side of this pass inclosed in part by the nut or collar O. The pass P is formed by the sleeve part S4 on the upper rollshaft and the sleeve part S5 on the middle roll-shaft. The pass P2 is produced by the sleeve parts S6 and S7, the pass P3 by the sleeve parts S8 and S9, the pass P4 by the sleeve-sections S10 and S12 on the middle roll-shaft, and

the sleeve-sections S13` and S1L1 on the lowery roll-shaft, the pass P5 by the sleeve-sections S15 and S16 on the upper roll-shaft, and the sleeve-sections S17 and S1S on the middle rollshaft, and the pass P1 by the sleeve-sections S1J and S20 on lthe lower roll-shaft, and the sleeve-sections S21 and S22 on the middle rollshaft of the train.

The shaft or core A is in each instance provided yvith shoulders I-I, against which the roll parts forming the initial andfinishing passes abut when attached, and the letters B designate a spline or feather longitudinally formed on each of the shafts or cores A, and the letters S22'designate a slot produced on ICO in the groove S22, the sleeve parts are prevented from turning on the rollshafts or core.

Each of the roll-shafts or cores A is at'each of its ends at T threaded to receive a retaining nut or collar O, C2, and C2, by which when screwed onto the threaded part of the rollshaft or core the detachable sleeve parts forming the initial and finishing passes are securely held in place where abutting against the shoulders H, with the other sleeve-sections arranged on the shafts or cores A between the initial and finishing passes when these intermediate passes are formed by sleeve parts instead of being made integrally with the roll-shafts A.

The initial and finishing passes of a train of rolls wear more rapidly than the intermediate passes, and where the initial and finishing passes are constructed to roll a bar having an entrant-groove which is longitudinally formed therein the tonguing part of the roll employed to form a part of the pass to produce this entrant-groove will wear away more rapidly than any other roll parts of the pass from the fact that there is a frictional contact with both sides of the tonguing roll part which tendsv to reduce it in width by wear, and this so occurringhas the effect to .reduce the width of the groove which the ton guing roll part forms in the bar, while the wear upon the other parts of the pass tends to enlarge its cross-area. lVhere accuracy is desired in the cross dimensions of the entrantgroove formed in the bar being rolled and shaped by the nishing pass to adapt its crosssections to answer the purposes for which they are designed, these attendantdifiiculties become very important. As Athe tonguing roll part of the finishing pass must from necessity have more entrant projection than the tonguing roll part of the initial pass, it Wears away more rapidly than the same part of the initial pass. When new rolls are required to meet this condition, they are very expensive and greatly increase the cost of the product.

As the rails of most of the railroads have the same general shape as regards their tread and waist, yet they have varying forms of base-flange, of which one is shown at b', Fig. 5, and another at b2, Fig. 6, and require fishplates having a corresponding form of V-' form recess to fit the rail-base for which they are to be applied. By having a tonguing roll part adapted to templet with each of these differing forms of rail-bases and with the tonguing roll part adapted to detachably connect with the finishing pass the same train may be made adapted to produce the desired forms of entrantgroove without changing the other passes of the train, inasmuch as the wear of the latter merely increases the thickness of the metal outside of the form groove, which until this increased thickness reaches considerable development is unimportant. In adapting this final pass P6 to produce in finishing effect (by changing the tonguing roll part of the pass) such measure of angularity and shape as may be required the tonguing part of the roll to be used is made to have the same bevel or taper as the ba-se of the rail to be fitted, with the tonguing roll part arranged to be passed on over the middle core or shaft A of the train to occupy the position shown at S22 of Fig. l and G7 of Fig. 2, with the tonguing roll part arranged on the shaft or core, with the spline B within the groove S23 in the tonguing roll part, with the latterabutting against the grooved roll part S21 of the same pass, and with thelast-named roll part abutting against the shoulder H of the shaft or core and with the nut or collar C2 screwed up on the shaft or core and with it in contact with the outersurface of the tonguing roll part of the pass to keep it in place.

All the passes of the train illustrated are provided with a tonguing roll part in differing measure of entrant projection and by which,las the bar is being rolled by the several passes, it is shaped in lateral distribution of metal at each side of the entrantgroove for the operation of the finishing pass, where the entrant-groove formed longitudinally in the bar must have a fixed measurement in cross-section to adapt it to the form of rail-base to which it is to be applied.

As the passes located intermediately of the initial and finishing passes serve only to give the rolled metal approximate form, there is less strain and wear at those points, and, if desired, the intermediate passes may be formed on the solid core or shaft, as shown at G in Fig. 2, with the initial and finishing passes formed detachably of sleeved parts, as shown at GQ G2, and G2, and seeured'upon the core or shaft by nuts G4, G5, and G.

When a pass-sleeve roll part contains in revolution in its circumferential face an entrant-groove, as shown at F of Fig. l, the wear upon the sleeve tends to widen out the groove, and by dividing the sleeve part on the line L of Fig. l when the pass-surfaces are worn away enough to widen out the crossarea of the groove which they inclose, by removing the sleeve parts of the roll and planing down what are their contact-surfaces when in position on the roll-shaft or core the required cross-measurement may be restored to the pass and the expense of a new set of rolls avoided. l

As the initial pass regulates by its form and area the amount of metal per lineal foot contained in the bar to be shaped by it and the intermediate passes and finally and accurately completed by the finishing pass, the latter and the initial pass are in a measure differently constructed as to form to do their functional part of the work, and while these passes operate connectedly they each really perform functions which would be the same IOS IIO

whether they were operated together or separately.

I am aware that it is not new to provide an ordinary train with rolls having passes formed therein by detachable sleeves, and I make no claim thereto, broadly considered; but with the construction herein described, wherein each pass is provided with a tongue and groove intermediate of the side walls of the pass,

whereby the metal is divided according' to a known means other than that shown may be` used to perform the same office. f

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

1. In a rolling-mill train, and in combination a plurality of rolls provided with initial, intermediate, and finishing passes each pass having a tongue and groove intermediately of its side walls for partly dividing a bar of metal longitudinally and maintaining approximately the same given ratio of metal in the opposite sides of the bar throughout the rolling operation, with the finishing pass constructed with itstonguing member detachably secured upon the roll-shaft which operates it substanf tially as and for the purposes set forth.

2. In a rolling-mill train and in combination, a plurality of rolls provided with initial, intermediate and finishing passes each pass havinga tongue and groove intermediately of its side walls, for partly dividing a bar of metal longitudinally, and maintaining approximately the same given ratio between the masses of metal in the opposite sides of the bar, throughout the rolling operation,with the initial pass being formed of sleeve parts, detachably secured to the roll-shafts or cores which operate them, substantially as and for the purposes set forth.

3. In a rolling-mill train and in combination, a plurality of rolls provided with initial, intermediate and finishing passes, each pass having a tongue and groove intermediately of its side walls for partly dividing a bar of metal longitudinally, and maintaining approximately the same given ratio between the masses of metal in the opposite sides of the bar, throughout the rolling operation, and having the initial and finishing passes formed in sleeves detachably secured upon the rollshaf-ts by which operated, substantially as and for the purposes set forth.

4f. The combination with a train of rolls having passes for rolling a bar provided. with a longitudinally-arranged entrant-groove, and having approximately in cross-section the form herein described; of an initial pass having a tonguing part arranged between two separately-formed side walls, with each of the sleeve parts forming the latter and the tonguing part connected detachably to the roll-shaft which operates them substantially as, and for the purposes set forth. Y

5. The combination with a train of rolls provided with passes by which a bar with a longitudinally-arrangedv entrant-groove may be rolled to have the form approximately in cross-section herein described; of a nishing pass made with a grooving part divided centrally and circumferentially to the groove in two sleeve-form parts; and a tonguing roll part and a sleeve-form part on the coperating roll; with the sleeve parts and tonguing parts ofthe pass detachably connected to the shafts or cores by which they are operated substantially inthe `manner as and for the purposes herein set forth.
