TEMPORARY RAIL JOINT.

Specification of Letters Patent.

Patented June 20, 1922.

Application filed February 23, 1922. Serial No. 538,625.

To an whom it may concern Be it known that 1, Louis A. WELSH, a citizen of the United States, residing at Camden, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Temporary Rail Joints, of which the following is a specification, reference being had to the accom' panying drawings. v

At times rails split or break, especially when subject to intense cold and as a result of heavy traiiic. If the split or break occurs between the joints of the rails, the broken adjacent ends are very liable to leave the ties, or become moved laterally, causing a derailing of the train, the result of which may be more or less very dangerous.

It is, therefore, the purpose to provide a temporary rail joint to be applied to the rails, not only to hold the rails in alignment, but also for preventing the rails from leaving the ties, thereby avoiding derailing of the train.

In other words the present rail oint is applied until the rails are permanently repaired, in fact until the broken rails have been replaced by new rail sections, and in this case the new rails are spiked to the ties in the usual manner, and the temporary rail joints removed.

A further purpose is the provision of a temporary rail joint including a plurality of clamps applied to the opposite sides of the rails, say for instance three on each side, one immediately where the break is located, and the others spaced on each side thereof a short distance from the center clamps, in combination with an elongated plate provided with operative wedge connections with the clamps, 'to hold the clamps securely in position;

A still further purpose is the provision of a series of clamps, each embracing the base of the rail and having a portion engaged with the side of the web between the base and the under portion of the ball of the rail, to reinforce the rail and hold the broken parts together and in alignment.

Additionally the invention has to do with the inclined outer edges of the clamps, which incline downwardly and outwardly, in combination with notches, which are not only correspondingly formed, but are wedge shaped, so as to not only wedge in engagement with the clamps, but also to bear upon .the downwardly inclined edges of the clamps, to insure holding them down, and

reduction of the invention to a more practical form for commercial purposes, the invention may be susceptible of changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed.

The invention comprises further'features and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

In the drawings Figure l is a view in perspective of the improved temporary rail joint constructed in accordance with the invention;

Figure 2 is a cross sectional view on line 2-2 of Figure 1;

Referring to the drawings, 1 designates a conventional form of tie (acting as an insert filler tie), and 2 denotes a rail, which has become broken as at 3,

In order to hold the two rail sections, which are caused to exist due to the break 3, in position, a plurality of clamps 4: is applied on each side of the rail 2. It will be noted that one clamp on each side of the rail 2 is placed so that its edge where it engages the rail covers the break or joint 8 in the rail, The other two clamps of each plurality thereof, are spaced short distances from the center clamp. Each clamp comprises a body portion 5, which embraces the rail, at a point adjacent the web, overlying the base, andfitting between the base and the under surface of the ball of the rail, as at 6, 7 and 8. In fact the part of the body which fits under the ball of the rail is curved to conform to the contour of the under surface ofthe ball, thereby not only preventing lateral movement of the rail, but also constituting a support and reinforcement for the ball of the rail.

The lower part of the body 5 of each clamp, substantially midway thereof is notched and provided with a recess 9, which embraces or receives the base of the rail,

thereby also reinforcing the rail, as well as preventing lateral movement. In fact a portion of the clamp engages under the base of the rail, and assists materially in holding the clamp in position. As previously stated the inner base. portions of the clamps at extend under the base of the rail, and if itwere not for sinking the base portions of the clamps 4 into the filler tie, the base of the rail would not engage flush with the upper surface of the filler tie. In other words the base portions of the clamps 4 are sunk into the filler tie for the purpose of permitting the base of the rail to engage flush with the tie.

The outer upper edge of each clamp is inclined outwardly and downwardly, and it will be noted that this inclined edge performs a very important purpose.

For instance a suitable plate 10 is provided, to rest upon the tie and is secured thereto by means of a spike 11, and is provided with a plurality of notches 12.

' The bottoms 1 3 of these notches or recesses are inclined correspondingly to the inclination ofthe edges 14 of the clamps, and since the plate 10 is secured to the upper surface of the tie, the clamps 4: are held in position, and prevented from leaving the tie, thereby preventing the rail sections on each side of the break 3 from leaving the ties.

It will be noted that the plate 10 is long enough, to span the distance or space between two ties, (not shown) so thatthis plate may rest upon two adjacent ties, and by inserting a filler tie (shown inFigure 1) between the two ties where the joint 3 may be caused to be formed in the rail, the plate lO may be fastened to the filler tie. In other words supposing the rail, due'to'intense cold,

should become broken at a point between two adjacent ties, an insert tie may be applied, and then the plate 10 may be fastened thereto, and hence prevent lateral movement of the broken adjacent ends of a rail section.

The notches or recesses 12 also have upwardly converging side walls. In fact the notches or recesses 12 are more or less wedge shaped, so that the side walls-of the notches or recesses may wedge in engagement with theopposite faces of the clamps 4, and thereby assist in preventing outward movements of the rails.

The notches or recesses 9 embrace the base of the rail sufficiently to hold the rail sections in position, and allow them to expand and contract incident to the change in temperature.

The invention having been set forth, what is claimed is 1. The combination with the broken ends of rail sections, of a plurality of clamps on each side of the rail sections, embracing the base thereof and fitting between'the base and the ball of the rail, an elongated holding plate spiked to the tie and having means in wedging engagement with the clamps to hold them against the rail sections and to prevent them from leaving the tie.

2. The combination with the broken ends of rail sections, of a plurality of clamps embracing the base of the rail and fitting between the base and ball of the rail, a plate secured to the tie and having means wedgingly fitting the clamps for holding them down and in embracing engagement with the rail sections.

3. The combination with the broken ends of rail sections, of a plurality of clamps embracing the base of the rail and engaging between the base and the ball of the rail, a plate secured to the tie and provided with a plurality of notches having a wedging engagement with the clamps to hold them in position and against the rail sections. 7

4. The combination with the broken ends of rail sections, of a plurality of clamps on each side of the rail sections, each embracing the base of the rail and engaging between the base and the ball of the rail, a plate secured to a tie and having notches, which are tapered or wedge shaped, so as to wedge in engagement with the clamps to hold the clamps in position.

5. The combination with the broken ends of rail sections, of a plurality of clamps on each side of the rail sections, each embracing the base of the rail and engaging between the base and the ball of the rail, a plate secured to a tie and having notches, which are tapered or wedge shaped, so as to wedge in engagement with the clamps to hold the clamps in position, the outer edges of the clamps inclining downwardly and outwardly, the bottoms of the notches or recesses inclin downwardly and outwardly, andoverlying the edges of the clamps, to hold the clamps down and in position.

In-testimony whereof I hereunto affix my signature. 7
