A CORPORATION OF NEW YORK.

PROCESS. FOR MAKING ROLLED STEP-JOINTS.

Application filed January 27, 1920.

T 0 all whom it may concern:

Be it ,known that I, BANOROFT G. BRAINE, citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Processes for Making Rolled Step-Joints, of which the following is a specification.

This invention relates to a method of manufacturing compromise or step rail joints from rolled bars thereby admitting of a distribution of metal to provide bars of this character which are of greater strength and efliciency than the cast type of joint bars in common use.

Primarily the invention therefore contemplates a new process for making step joint bars for railway rails which enables the manufacturer to utilize the rolling mill practice to effect proper distribution of metal throughout the bar in an expeditious I and economical way while at the same time providing for the formation of the bar in a manner whereby both outer and gage-side bars for opposite joints may be produced by the same operation.

lVith these and other more general objects in view which will readily appear to those familiar with the art the invention consists in the novel process steps'hereinafter particularized and which may be formed in connection with suitable apparatus and equipment in a rolling mill.

Various well-known and conventional instrumentalities maybe utilized in carrying out the invention therefore the accompanying drawings more or less diagrammatically illustrate the several phases of the method employed.

Accordingly I Figure 1 is a diagrammatic view of a bar showing the joint lengths laid off by dotted lines.

Fig. 2 is a perspective view of a bar'unit comprising two joint lengths for the gageside and indicating by dotted lines the line of shear cut to break up the unit into two joint lengths.

Fig. 3 is a perspective viewsimilar to Fig. 2 showing the bar unit severed.

Fig. 4 is aperspective view similar to Fig. 2 showing a bar unit for two outside bars.

1 Specification of Letters Patent.

Patented Dec. 14, 1920.

Serial No. 354,447.

Fig. 5 is a perspective view of the unit of Fig. 4 severed into the two outside bar lengths. I

Fig. 6 is a perspective view of a pair of joint bars formed in accordance with the present method, the bars being viewed from the gage-side of the joint.

Fig. 7 is a view similar'to Fig. 6 looking at the outside bar of the joint.

Similar reference characters designate corresponding parts throughout the several figures of the drawings.

In order to provide for joining rails of dissimilar section in track it is necessary that the joints which are termed step or compromise joints be so' constructed as to properly fit the fishing spaces and rail-bearing surfaces upon both sides of the dissimilar rails, and, on account of the running surfaces and inner sides of the heads of the dissimilar rails being in line, it is likewise necessary to provide the outer joint bar of different offset conformation from that of the inner or gage-side bar, thus involving in each step joint two bars commonly known as outside and gage-side bars. This dissimilarity of the outer and gage-side bars has heretofore made it very diflicult to economically manufacture such bars except by casting processes, but according to the present invention it is proposed to make these bars by a rolling mill process whereby the proper distribution of metal may be provided for while at the same time facilitating the making the different bars by the same operation.

I Inexplanation of the novel steps by means of which the aims of the present invention are attained it will be observed by reference to Fig. 1 of the drawings that the pri-,

mar feature'of the invention is to roll a continuous bar with the necessary prescribed off-setting according to the section of the rails for which the same is adapted, and

then to sever the bar centrally between the off-sets,- thus breaking up the entire rolled bar into rail joint len ths, each of which includes a bar section" tting the fishing of the larger rail and a bar section fitting the fishing of'the smaller rail.

Referring more fully to thenovel steps of the process which are substantially the same for making both the inside and outside joint bars, it will be noted from F ig; 1 of the drawings, that according to the invention claimed herein, a bar blank is subjected to the action of roll passes to thereby provide a bar with the necessary offsets, both vertically and laterally, each offset-portion of the bar'being of full rail joint length, as indicated at aa, in said Fig. 1 of the drawirfligs Withreference to the character of the 0 -setting, this necessarily depends upon the section of rails to be united, it being observed however, that in the case of thegageside bars only a vertical off-setting may be necessar, while the outside bars usually are deflected vertically as well as laterall Y to not only meet the differences in the fis ing spaces of the rails but also the difference in the width of the rails. In either event however, the initial step of the process remains the same, and the effect thereof is to produce a continuous bar having the general characteristics of the bar shown in Fig. 1 of the drawings. 7

After the bar has been formed in accordance with the step above set forth, it is proposed to sever or cut the same at points midway between the off-setting shoulders, thereby producing the necessary joint lengths. While the shearing of the rolled bar occurs successively midway between the shoulders of each ofi'set section designated a-a in Fig. 1, the result accomplished is in effect to produce units of construction extending between the lines 0.0, and when these units of construction, as per Fig. 2, are bisected on the shear lines C-C each unit of construction is broken up into two joint bars adapted respectively for use in joints at opposite sides of the track. By this step of the method therefore, the separate gage-side bars D and E are formed, each being of the required length to properly join or connect the ends of the dissimilar rails. The cutting or severing step by which the individual joint bars are formed may be carried out by any of the well known shearing instrumentalities employed for cut ting or severing rail joint bars.

The outside bars of the joint may be formed by the same method employed for the gage-side bars, as illustrated by Figs. 4

and 5 of the drawings. From these figures it Will be observed that the bar blank which results from the severing of the originally rolled bar strip may be severed on the line 0 0 to thereby provide the outside bars F and-G for the joint pairs. As previously indicated the outside bars are off-set'laterally as well as vertically in the off-setting step of the method, and are then severed in the' same manner as proposed in connection with the gage-side bars, namely at the inter- .mediate part of the off-set portion. Thus in this way the outside bars of a pair of joints are formed. p

Also in the case of one-end insulated joints where a space is desired under the head of one rail for insulation, the joint barscanbe 7 rolled by the same general method and then also cut to provide right and left bars for accommodating the insusite joint pairs may be obtained. This may be clearly observed from Figs. 6 and 7 of the drawings wherein the gage-side bar forms one side of one of the jloint pairs while in Fig. 7 the gage-side bar i represents the gage bar of the other joint pair. Similarly the outside bar F of Fig. 7 and the outside bar G of Fig. 6 are formed in the sameoperation. e

I claim 2-.-

1. A process for making step joint bars which consists in first subjecting the blank to a rolling pass producing a continuous rolled bar having off-sets therein at regular intervals, and subsequently severing-the bar,

at points intermediate the. locations of therolled bar having off-sets therein at regular 7 intervals and subsequently severing the bar midway of the off-set portions.

3. A process for making step joint bars which consists in subjecting a bar blank to means, for producing off-sets therein, and subsequently severing the deformed bar at themedial portion of the off-sets, thereby providing in one operation the bars of opposite joints.

4. A process for making right and left step joint bars which consists in first deforming a bar blank to provide off-sets therein, and subsequently severing the bar at the medial portion ofthe off-sets to there: by provide right and left bars of. opposite joints.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses. V
