ROBERT S. BOHANNAN, OIE
RAIL-J BIRMINGHAM, ALABAMA.
OINT.
Application filed October 8,
To all whom it may concern:
Be it known that I, ROBERT S. BOHANNAN, a citizen of the United States of America, residing at Birmingham, in the county of Jefferson and State of Alabama, have in. vented certain new and useful Improvements in Rail-Joints, of which the follow ing is a specification.
My invention relates to improvements in rail joints adapted to prevent the pounding caused by the wheels in passing from the approach rails onto the rails on track scales, draw bridges, turn tables and the like.
More particularly my invention relates to what I term easer joints and has for its particular object to improve and perfect the type of easer joint which forms the subject matter of Letters Patents Nos. 988,542,
, and 1,077,253, and which operates to gradually transfer the weight of the cars from the approach to the scale or bridge rails and vice versa, thus avoiding shocks, pounding and possible derailment at the joint.
According to my present invention the easer bar provides a continuous tread at the joint and is designed to be supported at its ends only upon bearings which are made adjustable so as to raise or lower the easer tread bar to give it the desired adjustment in height for different sized rails. The easer bar itself is preferably designed with rounded bosses at its ends and its bearings are formed by one or more brackets which i are suitably connected to the rail ends or to their supports so as to be held rigidly in position.
A further novel feature of my invention relates to the design of the brackets which serve as the adjustable supports for the easer bars. These brackets are shaped to fit into the web of the rail and are provided at their ends toward the-bar with side guards between which and the rail is formed a pocket for the reception of the easer bar which rests on a smooth tapered supporting surface forming the bottom of" each pocket. Moreover, these brackets are shaped to overlie with a flush fit the-base of the rail and may have lateral extensions by means of which they can be securely bolted to the rail plate or ties. To counteract more positively the tendency of these adjustable brackets to creep under the driving action of the wheels transmitted through the easer bar to the tapered bracket support therefor, the
Specification of Letters Patent.
Patented June 13, 1916.
1915. Serial No. 54,787.
outer face of the bracket through which elongated bolt holes pass for adjustably tying it to the rail web, is vertically corrugated and similarly corrugated washers are provided for the bolts. By this means the brackets are positively locked to the rail webs and may also be securely tied to the rail plates or track supports.
My invention further comprises the novel details of construction and arrangements of parts which in their preferred embodiment only are illustrated and hereinafter described, reference being had to the accompanying drawings, wherein Figure 1 is a top plan view of a rail joint provided in accordance with my invention, with a continuous tread easer bar. Fig. 2 is a side view of Fig. 1. Fig. 3 is a view from the inside of the brackets showing the manner in which the easer bar is housed and supported thereby. Fig. 4 is a vertical cross sectional view on the line 4-4 of Fig. 2; and Fig. 5 is a detail sectional view on the line 5-5 of Fig. 2 showing the corrugated portion of the bracket and the corrugated washer before it is clamped tight against the bracket.
Similar reference numerals refer to similar parts throughout the drawings. 8
According to my invention, as illustrated in the drawings, 1 and 2 represent the meeting ends of the approach and scale rails, but obviously 2 may represent a rail movable with a bridge, turn table, draw bridge or mine tipple. The sides of the rail treads are cut away vertically almost tothe web of the rail to provide a seat for the reception of the easer tread bar 3, which bar has the extreme ends of its top or tread edge beveled at a and gradually raised from the beveled portion to an apex at or near the center of the bar opposite the joint between the rail ends. The bar is adapted to gradually take on the weight of a wheel rolling over it and to support the weight after the fashion of an arch upon the two rounded bosses 5 and 6 at the ends of its bottom edge. A. bolt hole 7 is provided above the boss 6 and disposed concentric with the center from which the roundedbearing face of the boss is struck. The rail 1 is provided with a bolt hole 8 adapted to receive a bolt. 9 by means of which the easer bar is pivotally connected at one end to the approach rail 1. At its outer end this bolt is passed through a slot 10 formed in a vertical web I tween the tread and base of a rail and to i tion of bolts 16 which pass therethrough and abut, against the web thereof. The web is provided with two bolt holes for the recepthrough'the elongated holes 15 and receive on then" outer ends nuts 27 and washers 17, which latter have their inner faces vertlcally corrugated and adapted to interlock with corrugations 18 on the outer'face of the shank. By this means the bracket.
is held rigidly interlocked and prevented from creeping or slipping on its'rail connection. The inner end of the bracket is provided 'with a bottom face 19, which slopes to the side of the rail in conformity with the slope of the rail base so that it will fit snugly and bear fully upon the rail base. Along itsout'er side edge, the bracket may carry a laterally extending flange 20 which rests upon the rail support 21 or tie and is secured thereto by bolts 22. The rail on the other side is madefast to its support by a clamp plate 23, a bolt21 and a lug 25, or
, it may bemade fast in any other desired manner.
The side web 11 is braced to the flange 20 by end inclined webs 26 and is pro vided with clean out slots 28. The taper bearing face 13 is flat so as to afford a firm nd Wide bearing for the bosses 5 and 6 of the easer bar.
A bracket similar to that already described is usually provided for each end of the easer bar, but partially satisfactory results may be obtained from a P single bracket for the free end of the tread bar which is not generally bolted to the scale or bridge rail 2.
In operation, the brackets are first attached to the rails and the easer bar bolted to the approach rail. The bracket to which the bar is pivotally connected is then ad justed forward until its taper face 13 takes the full support ofthat end of the easer bar, whereupon the nuts 27 are tightened I and the corrugated washers 17 firmly clamped against the bracket to lock it in position. The bracket at the other end is then adjusted toward the easer rail until its taper face 13 brings the tread of the bar to the desired level, whereupon it is clamped into position and the apparatus is ready for service. In the case of turn tables or swing ing draw bridges, suflicient clearance should,
be left at the pivoted end ofthe easer bar to permit its free end to be swung high enough to clear the rail 2, and for other uses itis only necessary for sufficient play to be left for the free end of the bar to fol I low down with the bracket on the movable tread bar to the desired operating position, .but the most important function of the tread bar adjustment however is to adapt one size of easer bar for use with rails of varying section, so that only a few sizes of easer bars are required to be stocked to fit any standard size of rails.
