RAIL JOINT.

Application filed June 8, 1922. Serial No. 566,774. I

To all whom it may concern lie it known that I, Jenn B. MURRAY, a citizen of the United States, and a resident of li ilmington, in the county oi? ill. and.

Finte of Illinois, have invented a new and useful Improvement in liail Joints, of which the following is a "lull, clear and exact description.

My invention relates to improvements in ward leverage upon the rail sections as the trains pass thcreover. The construction of the present device is primarily designed to provide a longer leverage to the two memiers, whereby a greater lifting force is exerted by the device when a train passes,

thereover. j

A. further object of my inventionis to provide a rail joint which does away with the portions rojecting between the rail sections, as disclosed in my patented device.

-t further object of my invention is to provide a device of the character described in which only one bolt is used to secure the two members together.

A furtherobject of my invention is to [)YOVICIQ a device of the characterdescribed which supports the rail sections in. only two points, i

further object of my invention. is to p'rovhle a device oi. the character described which. is simple in construction and durable and eilicient for the purpose intended.

A further object of my invention is to ]I)1' )Vl 'l a device ot the character described which may be readily attached to a railroad track without any alterations in the latter being necessary.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be parpointed out in the appended claims.

Iiiv invention is illustrated in the accompanying drawings, forming part of this application, in which i igure l is a side elevation of the device as shown operatively applied to a railroad track,

Figure 2 is a section along the line 2--2 of Figure 1, and

Figure 3 is a plan view of one of the members of the device.

In carrying out my invention I make use oi? two sections 1 and 2 of an ordinary railroad track, these sections being supported by ties 3 in the customary manner. The device comprises two members which are identical with respect to each other and a description of one of the members will therefore suflice for both members. In Figure 2- it will be noted that the member B is provided with two arms 4: which are adapted to straddle the web 5 of the section 2. The arms t have an upwardly extending projection (5 adjacent to their inner ends and a downwardly extending projection 7 adjacent to their outer ends. The projections 6 are adapted to engage with the under side oi the head 8 of the ra l andthe projections are adapted to engage with the flange 9 of the rail. The armset are cast integrally with a depending portion 10 (see Figure 2).

The portions 10 of the members A and B are adapted to abut each other along the line ll. It will be seen from Figure -1 that the adjacent surfaces 01. the portions 10 slope gently away from the line 11 and that therefore the two members A and B may swing with respect to each. other the line 11 acting as: a fulcrum For the members. The member B has pins 12 which are adapted to enter recesses 13 in the member A, where by the two members are prevented from la tcral movement with respect to each other. in liigure 2. I have shown the portion 10 as being provided with, :1 base it, the base supporting the base 9 oil the rail. The portions 10 also have alined openings 15 through which a bolt 16 is disposed. From this constrnction it will be apparent that by merely tightening the bolt 16, the sections 1 and 2 'ot the rails are forced u nvardlyat their ad jaceut ends.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The members A and B are slid onto the sections 1 and Qand are secured in place by bolts 17 which are disposed in slots 18 of the arms 4: and in the ordinary openings provided in the rail sections 1 and In this manner the members A and B are adapted to move longillU the line 11 acting as a fulcrum.

tudinally with respect to each other and at the same time are prevented from lateral movement. As heretofore stated, the pins 12 and the bolt 16 also prevent the members A and B from lateral movement with respect to each other. It is obvious thereforethat the members are secured to each other in the minimum amount of time, since only three bolts have to be assembled to the members in order to secure the members in place.

When a train passes over the adjacent ends of the sections 1 and 2, the weight of the load tends to force the ends of the rail sections downwardly. The weight is car ried by the projections 6' andtends to force thelowcr ends of the portions 10 apart, the

This movement is prevented by the bolt 16 which securely holds the portions 10 from movement in an outward direction. The force of the weight is transmitted to the portions of the sections of the rails which are removed from the adjacent ends of the rails by the engagement of the projections 7 with the flanges-9 of the rails. In this manner the weight ofthe train passing over the rail sections is evenly distributed throughout a greater portion of the ties than ispossible with the ordinary fish-plate. ends of the sections 1 and 2 may be lifted by the members A and B when the bolt 16 is tightened. 'In this manner wear bet-ween the members A and B is readily taken up.

The device performs a simple means by which the downward play of the sections 1 and 2 is prevented when a railroad train passes thereover. As heretofore stated, the device is simple in construction, durable and efficient for the purpose intended, and is not likely to easily get out of order.

The adj acent abut each other along a horizontal. line disposed midway between the top and bottom of said rail sections, whereby said members are adapted. to swing about the line a fulcrum, integral depending portions carried by said members and disposed beneath said rail sections, and a bolt connecting said depending portions together adjacent to the lower ends thereof.

3. The combination with two rail sections adapted to abut each other, connecting members secured to both. sections, said members having integral arms adapted to straddle the webs of said rail sections, and having depending portions adjacent to their inner ends, said arms having upwardly extending projections adjacent to their inner ends, and having downwardly extending projections disposed adjacent to their outer ends. said members having their adjacent surfaces fashioned so as to abut one another along a horizontal line,a bolt connecting said depending portions together, and pins carried by one of said members and being adapted to enter recesses in the other member. 7
