To all whom it may concern:

Be it known that I, ETHAN I. Dorms, a

citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvanla, have lnvented certain new and useful Improvements in Rail-Joints; and I do hereby declare the fol-.

ingl their sections connected b splice bars or fis plates as now in use, an serve to reinforce or supplement such splice bar or fish plate constructions.

A further object is to so construct a rail joint chair as to provide a transverse bolster which shall also serve as a seat for the meetends of two rail sections.

ith these and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out' in the claims.

In the accompanying drawings; Figure 1 is a perspective view of a rail joint show ng one embodiment of my invention; Fig. 2 1s a transverse sectional view; Fig. 3 1s a longitudinal sectional view; Fig. 4 is a transverse section showing a rail in posit on; Fig 5 1s a perspective view of a rail omt showing a modified construction; Fig. 6 is an end view of the same; Fig. 7 is a transverse section; Fig. 8 a longitudinal sectlon and F1g. a side elevation of the form of the invention illustrated in Fig. 5; Fig. 10 is a side view and Fig. 11 is a perspective view, of another embodiment of my invention; Fig. 12 is an.

end view and Fig. 13 is a longitudinal sec tion of the construction shown in Figs. 11

, and 12; Fig. 14. is a transverse section of the same structure, showing a rail and fish plates in position; Fig. 15 is a side elevation of a further modification wherein a separate bolster is used; Fig. 15 is a perspective view of the separate bolster; Fig. 16 1s a plan view of the structure shown in Fig. 15, and Fig.

17 is a transverse section; Fig. 17 is a side elevation and Fig. 18 a plan view of another embodiment of my invention; Fig. 19 is an end view; Fig. 20 a transverse section and Fig. 21 a longitudinal section of the structure shown in Figs. 17 and 18; Fig. 22 is a side elevation, and Figs. 23, 24 and 25 are sectional views illustrating another embodiment of the invention; and Figs. 26 and 27 are views illustrating other modifications.

My improved rail joint chair comprises, in the embodiment of the invention shown in Fig. 1 of the drawings, a plate 1 which may be made of malleable iron or steel, and.

the chair may be made of metal capable of being pressed into shape with the use of dies. The intermediate portion 2 of the plate 1 is depressed somewhat below the horizontal plane of the end portions 3, as clearl shown in Fig. 3. The end portions 3 of the plate are adapted to rest upon the ties and are pro vided with spurs-4 to engage the latter, said end portions being preferably also made with holes 5 for the accommodation of spikes. The depressed intermediate portion 2 of the plate will span the space between ties and is provided centrally with a thickened portion forming a transverse bolster 6, the latter also serving to receive and provide a bearing for the meeting ends of two rail sections. At respective sides of the intermediate portion two of the plate, upwardly projecting strengthening webs 7 are provided. These webs may have convex upper edges extending from end to end .of the intermediate por tion 2 of the plate, and said webs are rovided with lateral flanges 8 projecting rom their convex edges. The flanged webs constitute compression members to sustain the load, brought to bear upon the bolster 6.

My improved joint chair will eflectually sustain the strain brought to bear upon the meeting ends of rail sections when the joint comes between the ties and will operate to reduce to a minimum, the hammering of the rails at the joint,efiicient trussed bolsters, such as indicated at 6-7-8, being provided to receive and sustain the meeting ends of the rail sections.

In the form of the invention shown in Figs. 5 to 9, the curved webs (project downwardly .as indicated at 9 an provided at their lower curved edges with flanges 10.

The flanged truss thus formed constitutes a member as shown in Fig. l, to sustain the strain which will come upon the bolster 6. In this construction, the connection between the bolster 6 and webs 9 may be further strengthened by means of ribs 11.

Tn the construction shown in Figs. 10 to 14, the central portion of the plate is removed as indicated at 2 and at respective sides of this open central portion, vertical webs 12 are formed so as to project above and below the horizontal plane of the plate,said webs being provided at their free upper and lower edges with lateral flanges 131-l. A bolster 15, which may be made in the form of an T-beam, extends across the central space 2 from one web 12 to the other and is supported by said webs. In Fig. it of the drawings, l have shown the bolster integral with the webs and the bolster 15 is so proportioned that its upper face shall be in line with the upper faces of the portions 3 of the plate and constitutes a seat for the meeting ends of the rail sections. If desired, holes 16 may be made in the portions 3 of the plate to reduce the weight of the latter. The plate or chair in this form of the invention, may be provided with spurs t and spike holes 5, as in the constructions previously described.

In the embodiment of the invention shown in Figs. 15 to l? the rail joint chair comprises three parts,viz. two truss members and a bolster. Each truss member comprises two plates l7l7 connected by a web 18 extending above and below the plane or the plates,-said web beingprovided at its free upper and lower edges with lateral flanges i9, 26. The truss members are suitably spaced apart on the ties, and connected by a transverse bolster 21 which, in this case, is made separate from the truss members and passed through holes 22 in the webs 18. The bolster 21 may be made in the form of an l-beam having its bottom portion curved or bowed downwardly, and provided at respective ends with transverse ribs 23 which serve to prevent displacement or spreading of the truss members.

Tn the construction shown in Figs. 17 to 21, the intermediate portion of the plate or chair is cut away as indicated at 2", and webs 2% are formed at respective sides of said central open portion. These webs are provided at their upper edges only with lateral flanges 25, and the bolster 26 is, in this construction, made integral at its ends with the webs 24;. Openings 2? may be made in the plate or chair to reduce the weight of the same.

Figs. 22, 23, 2d and 25 show splice bars 28 which may be of cast metal having webs 29 to depend between the ties and provided at their lower edges with lateral flanges 30 which may project outwardly or said flan es may project inwardly as well as outwar y.

nee les The webs 29 may be provided with holes 32 to accommodate a bolster 33, which latter may be the same in construction as that shown in Fig. 15*.

Tn the construction shown in Figs. 26 and 27, the intermediate portions of the respective truss members have a cross section re sembling that of an il-beam. The webs 34: project above and below the plane of the end portions of the chair,the upper edge of each Web being made straight and provided with lateral flanges 35, 35 projecting in opposite directions, and the lower edge of each web 34; being made curved and pro= vided with flanges 36, 36 projecting in opposite directions. The webs 34 are provided with openings 37 to receive the ends of a bolster 38, the construction of the latter being the same as that shown in Figs. 15* and 2d.

@ther changes might be made in the details of construction of my invention with out departing from the spirit thereof or limiting its scope and hence I do not wish to restrict myself to the precise details here in set forth.

Having fully described my invention what I claim as new and desire to secure by lhettors-Patent, is

l. A rail joint chair comprising two par allel' vertically disposed webs having lateral flanges at their tree edges and constituting truss members, and a transverse bolster ere tending from one truss member to the other. and sustained by said truss members, said transverse bolster constituting a member or? the chair and adapted to receive the meeting ends of rail sections.
