RAILWAY-TIE.

SIECIFIGATION forming part of Letters Patent No. 694,257, dated February 25, 1902. Application filed February 14, 1901. Serial No. 47,233. (No model.)

T0 at whom it may concern:

Be it known that I, CORTLAND DE OEW, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Railway- Tie, of which the following is a full, clear, and exact description.

Thisinvention relates to a metallic railwaytie to which the rails may be effectively connected and also by which the rails may be joined together without necessitating the common fish-plates.

The invention resides in certain peculiar features of construction which will fully appear hereinafter. y

This specification is a specific description of several forms of the invention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view showing various forms of the invention. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a section on the line 3 3 of Fig. 1. Fig. at is a section on the line 4 4 of Fig. 1. Fig. 5 is an enlarged plan view of one of the chairs. Fig. 6 is a section on the line 6 6 of Fig. 5. Fig. 7 is a plan view of one of the keys; and Fig. 8 is a detail perspective view of one of the spacers which are placed in the tie to hold the bolt, as will be hereinafter fully described.

The body of the tie is cast of any suitable metal, and it is formed hollow, with the bottom portion open, as shown bestin the crosssection of Fig. 2.

In Figs. 1 and 2, a indicates abar or what might be termeda double tie, which is used at joints in the rails, and (1 indicates a narrow or single tie which is used at points intermediate the joints. The rails b are mounted on the ties in the usual manner, and the rails are fastened to the ties a by means of chairs a, which bear one on each side of each rail and against the webs thereof. These chairs are held in place by bolts d, which pass through slots 0 in the chairs and have their heads fitted in undercut grooves 8, formed in the tie, these grooves being produced in thickened portions e of the tie, as shown in Figs. 3 and 4. Reference to Fig. 1 will show that the grooves e are ofkeyhole form, so that the heads of the bolts may beintroduced into the grooves and pushed laterally, so that they will not be removable by a direct upward movement. Spacer-blocksf are introduced into the slots e when the bolts are in place, as shown in Fig. 3, and these blocks bearing against the inner end wall of the respective grooves and against the bolts serve to prevent the displacement of the bolts. The blocks fare provided with eyes f, secured therein, and through the medium of which the blocks when it is desired may be readily removed. The chairs 0 are formed adjacent to the slots 0 with beveled surfaces 0 which are arranged in pairs, the members of which have a V-shaped disposition. Against these parts of the beveled surfaces 0 on the chairs 0 bear the correspondingly-beveled ends g of the spring-keys g. The keys g rest on top of the chairs 0 and have the bolts d passed through them. They are formed of spring material,

so that they will yield under the pressure of the bolt, and by screwing the bolt down firmly in place, as shown best in Fig. 3, the keys y will be caused to spring firmly against the chairs, and thus the chairs will be held securely and yet with a certain degree of yield, which will allow fully for the contraction and expansion of the metallic parts and for other inequalities of strain and movement which may exist from time to time during the use of the tie. The beveled ends g of the keys 9 bearing on the surfaces 0 will tend, further,to press the chairs against the rail. The V-shaped disposition of the parts 0 and g prevents relative sidewise movement thereof.

There is no material difierence in the form of the two ties aand a. Itis simply that the tie a is adapted to be used at a joint in the rails, and at this joint the chairs 0 are constructed with the two pairs of beveled surfaces c as shown in Fig. 5, and the two keys g are employed, as seen at the lower lefthand corner of Fig. 1. On the tie a the chairs are provided with but one pair of beveled surfaces 0 and a single key g is employed at each side of the rail. At the lefthand end of the tie a in Fig. 1 I have shown the left-hand keys gin place and at the righthand side of the rail, Where the joint occurs, I have illustrated the tie without the keys 5 and chair. At the right-hand end of the tie a, where no joint occurs in the rails b, the chairs 0 are provided each with only one pair ofinclined surfaces 0 and consequently with only one key for each chair.

IO By means of my invention the rails may be joined together without the fish-plates, and this is effected as shown in Figs. 1 and 2. A rod h is passed transversely across the tie a, immediately under the rails and longitudinally therewith. This rod has a cross-piece h, to which links it are connected, these links extending up on each side of the rail and being joined thereto by a bolt or rod h Now it will be seen that these devices clamp the rail firmly to the tie and prevent longitudinal movement of the rails, transverse movement of the rail being of course prevented by the chairs and keys. By duplicating on the other side of the tie a the parts h, h, if, and its, as

shown in Fig. l, the other rail may be firmly secured in the same manner. These devices are also useful for the purpose of preventing longitudinal movement of the rails between the chairs, while underall ordinary conditions 0 the force of the chairs bearing against the rails would be sufiicient to prevent this movement; but as a precaution the rod 7t and links 7&2 might be employed.

By means of this invention the detrimental results generally following the expansion and contraction of the rails may be avoided and the rails held to a perfect gage in all weather. Fish-plates and angle-bars are dispensed with, and the only bolts employed are the bolts 01, 40 which hold the chair in place. This rail may be used in conjunction with wooden ties by placing the metallic ties at various points along the railway, leaving the Wooden ties between them untilthe wooden ties are destroyed, whereupon the metallic ties may be substituted. The rails may be removed readily by releasing the chairs at one side, it being unnecessary to remove both chairs for this purpose. The tie being made hollow and beveled, leaving the bottom open, tends to find a firm bearing on the road-bed, and when once this bearing is reached the position of the tie will be exceedingly firm. By means of the construction described the bolt and the chair and key may be placed in or displaced from position at the top of the tie and without disturbingthe same, and the tie itself can be removed without interference with the other ties. I

Having thus described my invention, I claim as new and desire to secure by Letters Patent The combination of a rail, a tie-bearing thereunder, and having at each side of the rail an undercut groove, chairs bearing on the tie and against the rail at opposite sides thereof and formed with slots disposed transverse] y to the rail, the chairs having pairs of diagonally-disposed or V-shaped beveled surfaces, spring-keys bearing on the ties and having correspondingly-beveled surfaces engaging the beveled surfaces of the chairs, and bolts, the heads of which are fastened in the undercut slots, the said bolts being extended upward through the chairs and connected with the keys.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CORTLAND DE CE W.
