HENRY KOI-ILMYER, 0F LORAIN, OHIO.

METALLIC TIE roe naILwAYs.

To all whom it may concern Be it known thatI, HENRTKOHL YER, acitizen. of the United States, residing at Lorain, in the county of Lorain and State of .Ohio, have invented certain new and useful Improvements in Metallic Ties for Railways, of which the following is a specification.

This invention relates to metallic ties for supporting rails,and more particularly to improvements in such ties for street railway purposes.

The principal object of the invention is to provide ametallic tie, so designed that it will slightly resiliently yield under ,a load and thereby prevent jarring of a vehicle traveling over the track. This is very desirable, for it will not only add to the life of the vehicle and save the contents from damage due to jarring, but also both operators and passengers will be able to ride with greater comfort.

A further object of the invention is to attain the above results with a metallic tie of simple and comparatively inexpensive construction that is efficient in service.

In order that the invention may be clearly understood, the same will be fully described in connection with the accompanying drawings, which simply illustrate a preferred form of the invention, and'the novel features thereof will be distinctly pointed out in the appended claims.

In the drawings similar characters of reference designate corresponding parts.

Figure 1 isa cross sectional view of a metallic tie constructed in accordance with my invention, Fig. 2 is a similar view, illustrating the position of the tie when supporting a load, Fig. 3 is a side elevation of a fragmental portion of a tie, and Figs. 4 and 5 illustrate modifications of Fig. 1.

Referring to the drawings, 1 represents the head of the tie, which may have a straight flat face 2 as shown, or may be of any other desired shape, for conveniently supporting a rail. Depending, centrally from the head 1, is a longitudinally extending tongue 3, which is adapted to fit between the upper portions of the vertical sides 4 and 5 of a base member 6. The up er edges of the sides 4 and 5 are preferably ent outwardly and inclined slightly upwardly at S to conform to the shape of the underside of the head 1. The head of the tie is seated upon the outwardly bent portions 8 and is Specification of Letters Patent.

secured to the base member by means of a pair of cleat strips 9, which are bent inwardly and snugly against said upper edge portions 8 of the sides 4 and 5. As the head of the tie is preferably made of steel and; formed by the rolling process in the ordlnary manner, the longitudinal cleat strips 9 originally project straight as shown in dotted lines Fig. 1, so that they will fit over the outwardly bent edge portions 8, and being ductile maybe bent inwardly against the same. For the more securely fixingthe head of the rail to the base member, bolts 10, or rivets, may be used, which pass through the sides 4 and 5, and also through the tongue 3. If desired, the upper. edges of the sides 4: and 5 may be made as shown at 11 in Fig.4, and fit into longitudinal grooves 12 in the head of the tie.

The most important feature of this inventlon resides in the construction of the base member 6, which is formed of one piece of resilient steel plate. As will be noted, the base member-is substantially of the same shalpe as the web and base of an ordinary rai bend outwardly at 13, and form downwardly inclined top plates 14, the outer longitudinal edges 15 of which turn under and into the base plate 16.

In the modification shown inFig. 5, the head of the tie consists of the two oppositely extending longitudinal flanges 17 formed integral with the sides of the base member. A rivet 18, or bolt, being used to secure the upper portions of the sides together.

Any suitable means may be used to fix the track rails to the head 1 of the tie, and the base member 6 may either rest upon the ground or be anchored to a suitable foundation.

It will be readily understood, that when a vehicle passes over rails supported on resilient metalie ties such as set forth and described, the weight of the vehicle will cause the base members of the ties to springingly yield at 13 and 15, which tends to assume the shape illustrated in Fig. 2, and therefore the vehicle will ride smoothly over the track, thus preventing jarring of the same or its contents, and the operators or passengers can ride with comfort.

Although a metallic tie constructed as herein described will serve the intended purpose,it will be understood that slight modi- The before mentioned sides 4 and 5 1.

2. In a metallic tie, the combination of a head, and a base member supporting" the head, the base member consisting of resilient plate material bent to form a pair of spaced vertical sides, said sides being bent out wardly and inclined downwardly forming top plates, and the top plates having their oiiter longitudinal edges turned under to form a base plate, substantially as described.

3. In a metallic tie the combination of a head, the head having a depending longitudinal tongue,-and a base member for supporting the head, the base member consisting of resilient plate material bent to form a pair of spaced sides and a hollow base, said head resting on the upper edges of the sides, and said tongue being interposed between said sides, substantially as described.

4. In a metallic tie the combination of a head, the head having a depending longitudinal tongue, and a base member for supporting the head, the base member consisting of resilient plate material bent to form a pair of spaced sides and a hollow base, the upper edges of said sides being bent outwardly, said head being seated on said outwardly bent edges, said tongue being interosed between said sides, and means integral with the head for engaging said outwardly bend edges, substantially as de- ,scribed.
