CHARLES A. PSILANDER, OF EASTON. FENNSYLVANIA, ASSIGNOR TO WILLIAM WHAR- TO'N JR. & CO., INCORPORATED, PENNSYLVANIA.

OF EASTON, PENNSYLVANIA, A CORPORATION OF METHOD AND MEANS kFOR lVfAKING COMPROMISE ANGLE BARS.

Application filed July 1.

To all whom t may concern.'

Be it known that I, 'CHARLES A. PsrLAN- DER, a citizen of the United States, residing at Easton, in the county of Northampton and State of Pennsylvania, have invented certain new and useful Improvements in Methods and Means for ls/faking VCompromise Angle Bars, of which the following is a specification.

This invention provides a method and means for effecting variable osetting of bars and the like, for example, compromise bars or fish bars of straight or angular form.

In making compound joints, lfor example so-called compromise bars it is often necessary to offset the upright and foot portions, and this operation has heretofore been done in two distinct steps. Moreover, since it is often necessary to provide the upright and foot portions with different degrees of offsets, the two step operation is a substantial doubling of the time and labor required for a single bend or offset.

According to my invention, both the upright and foot portions of the bar are simultaneously offset laterally in a single pressure movement, and the relative degrees of offset as between such portions may be varied at will.

The invention provides novel apparatus for use in conjunction with, for example, a bulldozer, so that any desired degree of offset may be provided-in the foot or upright, and any relativedegree of offset in both the foot andupright, the offsetting being effected in a single pressure movement.

The apparatus for the performance of my invention preferably includes co-axially mounted and longitudinally split or partible barrel dies. The two elements of the respective dies areinteriorly shaped to snugly receive the bar to be offset. vThe dies are mounted for rotative adjustmentv `between spaced jaws in a bulldozer or equivalent-machine. The jaws are so 'constructed and arranged as vto .becapable of limited move- -ment in the respective headsof'the' bulldozer or other machine, liners `being interposed between the jaws and heads to controlthe desired offsetting operation. Thus vit willbe understoodthat when the .jaws close j upon the diesiin.response,t0-pressure of the 1922. Serial No. 572,242.

heads, the dies will have an angular movement determined by the relative thickness'of the liners employed. V.'I`hisevidently results in a. corresponding offset in the bar.

rlhe invention contemplates the offsetting of both hot and cold bars, but as more pressure of course will be necessary for cold bending and it is desirable to use the ordinary bulldozer, the bars are preferably heated, and any character or 'degree of offsetting effected at one heat.

In the accompanyiim` drawings,-

Thatfpart of the apparat-us through which the improved method is carried out involves aseries of (in this example two) barrel shape ory cylindrical dies l and 2, each con-` structed of longitudinally co-operating sections 3 and 4. The proximate' faces of the die sections are formed as at 5, to receive a bar 6, and the respective halves ofeach die'are hingedly connected at their outer ends by U form brackets 7, pivotally connected bybolts 8, at points remote from the die proper, in order to permit a full opening of-each die-' The barrel dies arerecessed as at 9, and provided with coincident openings 10, for the reception, if necessary, of suitable locking provisions.

Each barrel die is mounted on inner and outer carriage trucks 1l and 12, the inner truck being beneath the inner or adjacent ends of the barrel dies and the outer trucks at the outer endsthereof. The inner trucks carry truck supporting rollers V13 and die-- supportingirollers lhwhile the Outer trucks carry truck-supporting rollers Y15 and Adiesupporting rollers 16. Thegouter trucks are also provided with an `.upstanding flallge.V 17

i formed with a series of variable graduated holes 18, the fiange 17 of t-he outer truck overlying the outer ends of the barrel dies. rllhe ends of the barrel dies are also formed with openings 19, preferably in the upper and lower series, so that any of the open- .ingsr 19 may be broughtinto registry with the openings 18 of the flange 17, for the reception of pins to hold the barrel dies in any position of rotative adjustment desired, the purpose of which will later appear. The trucks are secured relatively by rods a passing through elongated slots in the inner trucks and having threaded terminals to receive lock nuts c, d. The rods are formed so as to have a certain degree of spring qualit-y or fleXure in order to permit relative movement of the trucks in the offsetting movement of the dies, and the elongated slots ZJ facilitate the return of the parts to normal position. ln addition to the adjustment afforded by the lock nuts c, d, the inner trucks may be spaced by the provision of separators c carried by the rods, the separators, when present, operating in conjunction with Cotter pins The barrel dies are each held between opposing jaws 20, 21, having a limited sliding connection as by bolt and slot connector 22, with the heads 23" and 24': of a bulldozer or other similar machine. The jaws have thus a limited independent movement in the heads, one of which heads is usually stationary, and :the other movable under pressure.

`Liners 25 of Varying thickness are employed with the apparatus, these liners being interposed between the jaws 20, 21, and the heads 23, 24. Obviously, if a thin liner is employed behind the jaw 2() of one barrel die and a thick liner behind the jaw 21 of the same barrel die, aud this arrangement be reversed with respect to the other barrel die, then when the jaws are brought together onto the dies, the latter will be offset a distance equal to the difference between the thick and thin liners. Therefore, the offset depends upon the relative thickness of the liners employed, so that the machine readily lends itself to any degree of offset which may be found necessary. The` truck or Ycarriage on which' the dies are mounted is so constructed as to have a certain amount of fleXure which provides for more or less tolerance between theV sets of dies. There is also a slight difference, say one-sixteenth of an inch in the end openings. of the dies and the complemental pinreceiving openings in the truck or cradle forming a roller path for the dies. The

" barrel dies are properly spaced and shearingof the bar is prevented by distance adjusting screws 26. j

I' it is o`nly necessary to offset the bal` in a .vertical direction, as for iinstanceV a bar for use between a new or full section and a worn section of rail, the vertical part of the bar should be in a horizontal plane as shown at A-A in Fig. 1. And if a lateral offset only is required, as for instance between two rails of different width heads but same fishing section, the barrel dies and the bar are adjusted so as to be at an angle of O to the line of pressure. Since both vertical and lateral offsets :12 and y (Fig. 7) are required in compromise bars, the proper turning of the barrel will insure any proportions between the horizontal and vertical. For instance, if the vertical offset is three-eighths and the horizontal offset is three-thirty-seconds, the hypothen-use is the difference in the lining of the jaws, and this regulates or controls the angle to which the line A-A should be adjusted from the horizontal, either by turning the barrel clockwise or anti-clockwise according to whether a right or left hand joint is desired. The angle being det-ermined, the dies are secured by pins 27 eooperating with the holes 18 and 19. If the pin holes in the barrel are given a somewhat larger spacing, say one-sixteenth of an inch, than the holes in the carriage, a very close setting or adjustment can be provided for.
