BAIL-JOINT.

Application filed September 12, 1917.

To all whom it may concern:

Be it known that I, MERLE J. VVIGHTMAN, citizen of the United States, residing at Seattle, in the county of King and State of ivashin ton, have invented a certain new and USQIUl Improvement in Rail-Joints, of which the following is a specification.

My invention relates to improvements in rail joints and more particularly it relates to improvements in "ail joints, one of which is described in United States Letters "Patent No. 1,183,260, granted to me on date oi May 16, 1916 and the object of my present invention (like that of the invention disclosed by said Patent do. 1,183,260) is to provide a rail joint so constructed that the abutting ends of contiguous rails shall be sounited that there shall be no relative motion of said abutting ends, and that any waye action under the weight of a passing train shall be the same through the rail joint as it is throughout the lengths of said rails, and that the top su faces of the heads of said rails shall be maintained in alineinent as rigidly and iirinly as they would be ii-they were welded together; but, a further ob ect of my present invention is to provide a rail. joint which shall enibody parts so constructed and so associated with the tie upon which said rail joint is located that said parts and said tie shall conjointly act as an anchor or anti-creeper, to prevent the oined rails from creeping or moving in lengthwise directions in response to the travel oi heavily loaded trains on said rails.

l accomplish these objects by devices llustrated in the accompanying drawings, wherein Figure 1 is a plan view of the abutting end portions of two rails joined by a rail joint embodying my invention;

Fig. 2 is a view of the same in side elevation; I

Fig. 3 is a view or the same in vertical section on broken line 3, 3 of Fig. 1; and

Fig. iis a perspective view oi an important detail of the same.

Referring to the drawings, throughout which like reference numerals indicate like parts, the abutting end portions of two rails 5 and 6 are united by fish plates 7 and 8 which, in the usual manner, are fastened thereto by bolts 9 and 10.

As indicated in Figs. 1 and 3, each of the Specification of Letters Patent.

fish plates 7 and S is provided with an integral flange, as flanges 11 and 12 respectively, that projects outwardly from its bottom edge portion for a distance beyond the adjacent edges of the base portions of the rails 5 and 6, a portion of the under side surface of said flange being evenly seated on the top surfaces oi" said i ase portions of the rails 5 and 6, and the surface of the top edge portion of said fish plate being in engagement with the under side surfaces oi the heads oat said rails 5 and 6.

The outer edges of the flanges 11 and 12 throughout the distance letween their respective opposite ends are curved to form an arc of a true circle, as shown more clearly in Fig. l.

The abutting end portions of the rails 5 and 6 being securely united by the fish plates 7 and 8, the flanges 11 and 12 of said tish plates are disposed in an arch-like relation to a supporting tie plate, of the form shown by perspective view in Fig. 1, the curved outer edges of said flanges 11 and 12 being disposed to engage with and to be supported by the upwardly diverging surfaces lei of the inner sides oi oppositely disposed curved flanges 15 and 16, respectively, which are integral with and project upwardly from two spaced horizontal portions 1'? of said supporting tie plate.

As thus disposed, the abutting end portions of the rails 5 and 6 serve as the key member of an arch whose other members include the fish plates 7 and 8, their integral flanges 11 and 12, and the flanges 15 and 16 oi the supporting tie plate.

It is manifest that by reason of the bolts 9 and 10, and the curved edges of the flanges 11 and 12 disposed in engagement with the surfaces lei oi the curved flanges 15 and 16, the rails 23 and 6 cannot be moved in endwise directions with respect to the support ing tie plate.

The supporting tie plate is disposed with its two spaced. horizontal portions 17 resting on the top surface of a railroad tie 18, which horizontal portions 17 are united by integral flanges 19 which extend downwardly preferably in diverging planes from the opposite edge portions thereof to engage with the upper corner edges of the opposite vertical. sides of said tie 18, as more clearly shown in Fig. 2. The angular or inclined arrangement of the flanges 19 insures a snug engagement thereof with the railroad tie and provides an arrangement whereby the device wedgingly engages the tie to insure against sidewise movement of the device. This arrangement also enables the device to be firmly positioned on ties of differing widths as will be apparent.

' Between the two spaced flanges 15, and between the two spaced flanges 16 of the supporting tie plate, the horizontal portions 17 are each provided with a recess, as recesses 20, through which a rail spike, like the rail spikes 21 and22, may be driven to extend downwardly into the railroad tie 18 until its head forcibly engages with the upper side of the edge portion of the adjacent one of the flanges 11 and 12 as inclicated more clearly in Fig. 8.

Thus, the spikes 21 and 22, by their engagement with the walls of the recesses 20, act conjointly with the flanges 19 of the tie plate to anchor said tie plate against sidewise movements on the railroad tie 18, while the curved surfaces 14; of the several flanges 15 and 16 by their confined engagement with the curved edges of the flanges l1 and 12,1'espectively, serve to anchor the fish plates '7 and 8 and the joined rails 5 and 6 against movements in lengthwise directions of said rails 5 and 6.

Obviously, the dimensions, and to some extent, the forms andarrangement of parts of my rail joint, may be changed without departing from the spirit of my invention.

hat I claimis i 1. A rail joint of the class described which embodies a tie plate that includes two spaced and horizontally disposed flat portions that are integrally united by flanges which project downwardly from the side edge portions thereof, each of said flat portions being provided with a recess disposed in its inner edge portion and both of said inner edge portions having integral, curved flanges that project divergingly upward therefrom. V

2. A rail joint of the class described which embodies a tie plate that includes two spaced and horizontally disposed flat portions that are integrally united by flanges which project downwardly from the side edge portions thereof, both of the inner edge portions of said flat portions hav ing integral, curved flanges that project divergingly upward therefrom. 7

3. A rail joint comprising, in combination with a supporting'tie having opposite flat vertical sides, a tie plate including a flat portion constituting a horizontal tie bearing surface, and dependent flanges integral with said flat portion and inclined outwardly from the vertical to produce angular engagements thereof with the flat vertical sides of the tie, said flanges projecting downwardly from the opposite side edges of said flat portion.
