BOLT-SUPPORTING CONSTRUCTION FOR RAIL-JOINTS.

To all whom it may concern:

Be it known that I, CLARKSON A. DISBROW, citizen of the United States, residing at New Rochelle, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Bolt-Supporting Construction for Rail-Joints, of which the following is a specification.

This invention relates to an improvement in rail joints providing a practical and economical means for bracing and stifi'ening rail joint bolts, adjacent the rail webs, to enable them to better withstand abnormal bending stresses.

Certain track conditions lead to frequent instances of abnormal stresses being thrown upon the joint bolts, and this becomes very pronounced in that type of rail j oints requiring the use of much longer bolts than employed in connection with the ordinary angle bars. While the heat treatment of track bolts has tended to neutralize to a considerable extent the liability of joint bolts yielding to bending stresses, nevertheless these stresses are so severe at times in connection with long joint bolts that a supplemental bracing support therefor is very desirable to prevent the bolts from bending due to the contraction of the rails, as well as due to load conditions in cases where the track is more or less free to run.

Accordingly, the invention chiefly has in View a simple and effective means of giving to the joint bolts an additional bracing support between the rail web and the webs of the splice bars to minimize the tendencyeof the bolts, especially if long bolts, to be or cut by bending stresses.

With these and other objects in view which will more readily appear as the specific embodiments of the invention are understood, the same consists in the novel arrangement of a bolt supporting element in connection with a splice bar hereinafter described, illustrated and claimed.

The invention is susceptible of consider-.

able modification without departure from the spirit thereof, but certain practical embodiments are suggested in the accompanying drawings, in which Figure 1 is a cross-sectional view of a rail Specification of Letters Patent.

Patented Nov. 18, 1919.

Application filed May 3, 1919. Serial No. 294,504.

invention, wherein the bolt supporting member may be a separate plate for each bolt.

Fig. 3 1s a sectional view on the line 33 of Fig. 2 showi the seating of the central bolt plate wit in the channel and at the inner side of the splice bar.

Fig. 4: is a view similar to Fig. 2 illustratnganother modification in the bolt supportmg member and the method of attaching the same. A

Fig. 5 is asectional view on the line 55 of Fig. 4.

The distinctive feature of the present inyention is that of a bolt brace and supportmg member held in a desirable position between the splice bar and the rail web so as to function as an auxiliary support for the central portion of the bolt to stiffen and brace the same against bending stresses that may be imposed thereon from track and' load conditions or from contraction and ex- P81181011. of the rails. This bolt brace and supporting member is preferably carried by the splice bar as a rigid and substantially integral part thereof so that the said memher will not only function to assistthe bolt in withstanding abnormal stresses but also as a reinforcement for the splice bar itself since it will add strength to the splice bar thus making it possible to use a bar of lighter weight than would ordinarily be used without the added feature of the said auxiliary member.

To illustrate these desirable features of the resent invention there is shown in Fig. 1 o the drawings a rail joint of the type including in combination with the rail R a splice bar 1 having its web disposed at'a much greater distance outward from the rail web than an ordinary angle bar, thus requiring the use of long joint bolts which will be materially aided in withstanding bending stresses by the improvement contemplated by the present invention. In the illustration referred to the auxiliary bolt brace and supporting member is shown as consisting of a continuous strip or plate designated by the numeral 2 and arranged in upright position at and along the inner side of the bar. The said strip or plate is intended to be held by the splice bar in an advantageous location adjacent the rail web, that is, in an intermediate position spaced from both the rail web and the splice bar web so that it will effectually function as a brace and support for the intermediate pertion of the bolt. To provide for thus positioning and holdin the auxiliary member 2 the present invention rovides for the fast and rigid attachment 0 the said member to the inner side of the splice bar. This fast and ri id attachment may be effected by any suitabiineans but preferably by a Welded union between said member and the splice bar. -Such welded union may be satisfactorily made by the oxy-acetylene or other well-known welding operations and according to the illustration of Fig. l of the drawings the upper and lower edges of the auxiliary member 2 may be seated in rabbets or mortises 3 formed at the inner side of the head and foot of the splice bar and permanently secured therein by scarf or fillet welds 4-4. These provisions permanently unite the auxiliary member 2 with the splice bar as a permanent part thereof so that the mere application of the splice bar serves to properly position the auxiliary member as a brace and support for the bolts.

The embodiment of the invention shown in Fig. 1 of the drawings includes another desirable feature of construction, namely that of having the auxiliary member or plate 2 swelled or enlarged toward the center thereof so that the bolt bearing holes 5 punched through said member or plate will provide a definitely extended or enlarged bearing for the joint bolts, and thereby more fully safeguarding the bolts against bending under stress.

Instead of the auxiliary member or plate 2 being in the form of a continuous plate extending from end to end of the splice bar the same may consist of an individual or single plate 2 for each bolt. This is shown in Fig. 2 of the drawings, and the single or individual plate may be conveniently seated within the channel at the inner side of the splice bar, as shown in Fig. 3 and permanently fastened thereto by welded connections 6 at the corners of the plate as may best be seen from Fig. 2 of the drawings. And, according to the embodiments suggested in Figs. 4 and 5 of the drawings a continuous strip or plate 2 may simply be held within the channel at the inner side of the splice bar by means of fillet welds 7, at the top and bottom thereof, without alteration at all of the splice bar or of the plate itself. Also, the illustrations of Figs. 4 and 5 suggest the feature of having the bolt bearing hole 5 through the plate of a greater vertical diameter than horizontal diameter so as to allow ample freedom when inserting the bolt. Furthermore, it will be understood that any charac of welding be to effect unien be tween the auxiiiary bolt brace and support-- ing member and the splice bar, such for in stance as intermittent spot welding instead of the-continuous Welds shown, all of which expedients however are now Well-known in the art o f w elding.

Other modifications will be apparent'to those familiar with this art without further description and it will be understood that changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
