METALLIC CROSS-TIE AND RAIL-FASTENING.

SPECIFICATION forming part of Letters Patent No. 656,799, dated August 28, 1900. Application filed April 25, 1899. Serial No. 714,445. (life model.)

To all whom it may concern:

I curing the rail to the cross-tie.

Be it known that I, AARON B. ALLEN, a citi-' zen of the United States, residing at Pueblo, in the county of Pueblo and State of Colorado, have invented certain new and useful Improvements in Metallic Cross-Ties and Rail- Fastenings; and I do hereby declare the following to be afull,clear,and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to metallic crossties and rail-fastenings for railroads.

My object is to provide a tie that while reliably serving its purpose will be strong, durable, and cheap and'onethat can be readily substituted for the ordinary wooden tie, together with a reliable rail-fastening adapted to cooperate with said metallic tie.

The construction of my invention is clearly illustrated in the accompanying drawings, which form a part of the application.

For convenience of reference similar numerals are used to refer to similar parts throughout the various figures of the draw- 1ngs.

Figure 1 is a top plan view of my improved metallic tie. Fig. 2 is an end view thereof. Fig. 3 is a perspective of the yoke used in securing the rail to the tie. Fig. at is a perspective View of my tie, showing the rails secured thereto. Fig. 5 is a sectional view more fully illustrating the manner of securing the rail in operative position. Fig. 6 is a view of the bolt used. Fig. 7 illustrates one of the two ears which may be used .instead of the yoke illustrated in Fig. 3 in se- Fig. 8 illustrates the form of aperture employed in the cross-tie or in the bridge-plate when the ears illustrated in Fig. 7 are used. Fig. 9 illustrates a varied form of securing-ear which may be used. Fig. 10 illustrates a cross-tie provided with apertures adapted to cooperate with the kind of ears illustrated in Fig. 9, two of said ears being placed in operative position. Fig. 11 is a perspective view of the bridge-plate used with this style of securing ear. Fig. 12 is a perspective view of a crosstie having the ears withdrawn from the top section of the tie and being integrally formed therewith. Fig. 13 is central longitudinal section of Fig. 12. Fig. let is a perspective View of the bridge-plate, having integral ears similarly formed to those illustrated in Fig. 12.

When my tie (designated by the numeral 1) is disposed with the open side downward, as

illustrated in Figs. 1, 2, and 4, it is provided near each end thereof with the two parallel transverse slots 2, separated from each other by a distance equal to the width of the base of the rail. The slots 2 are of asize and shape to snugly receive the ears 3 ofthe yoke i, Fig. 3. These ears are provided with the threaded aperture 5, designed to receive the bolts 6, the inner ends of these bolts being provided with tapered or conical ends. WVhen it is desired to secure the rails in position on the ties, the ears 3 of the yoke 4 are passed upwardly through the apertures 2 till the body 7 of the yoke rests against the under side of the top section of the rail. The base of the rail is then placed on the tie between the ears and the bolts 6 are screwed home in the ears 5, the conical ends of said bolts coming firmly in to contact with the inclined faces of the rail-base, thus rigidly securing the rail in position, as illustrated in Figs. at and 5. The heads of the bolts 6 are round and are provided with the apertures 8 in order that said bolts may be easily screwed home in the ears 3 or removed therefrom when occasion requires. The upward pressure against the conical ends of the bolts when in their operative'positions has a binding effect,which tends to prevent the bolts from working loose.

The outer ends of the bridge-plate are sufficiently extended to permit them to be bent around the outer edges of the flanges 11 of the cross ties. This serves 'to prevent the tie from spreading. The bridge-plate Slat one side thereof has the integral portion 12 bent downwardly substantially at right angles to the main body thereof. This downwardlyextending part has its bottom edge resting against the bottom section of the tie and its side edges snugly received between the vertical walls thereof. Hence it is apparent that while my improved bridge-plate prevents the tie from spreading, as already explained, it also, by means of this downwardly-extending section 12, resists any tendency of the two Vertical walls to approach each other. Moreover, by means of this downwardly-extending section 12 a part of the weight of the rolling-stock is distributed to the bottom section of the tie, so that the vertical walls do not have to bear the strain of the entire load that passes over the track. The loweredge of the downwardly-extending section 12 is provided with the slight cut-away portion 13, which in rainy weather permits water to seep out of the trough, so to speak, of the tie.

In Fig. 7 I illustrate a form of ear two of which are adapted to take the place of the yoke shown in Fig. 3. This car consists of the head 14 and the body portion 15, connected by the narrow portion or neck 16. When this form of ear is employed, the crosstie or bridge-plate, whichever is used, will be provided with the cruciform slot 17. (Illustrated in Fig. 8.) This slot consists of a cutaway portion in the shape of a cross, having I the longitudinal extension 18 and the lateral extensions 19, the former extending in the direction of the longitudinal reach of the tie and the latter at right angles thereto. When it is desired to secure the rail in position, the body portion 15 of one of the ears illustrated in Fig. 7 is passed downwardly through the lateral extension 19 of the cruciform slot. The ear is then moved sidewise, so that the neck 16 is received by one of the longitudinal extensions 18. Then the other ear is entered in the same manner and received by the other longitudinal extension 18. The longitudinal extension of the slot 17 is such that when the securing-ears are in their places there will be just sufficient space between them to receive the base of the rails, which are next placed in operative position and secured there by pass ing the bolts 8 through the apertures 20 in the securing-ears.

Where the width of the base of the rail is increased by the addition of the fish-plates at the ends of the rails, the longitudinal extensions of the cruciform slot must be correspondingly greater, so as to receive the width of the rails, with the fish-plates added, between the ears cooperating with said slots. In this case the transverse slots 2, Fig. 1, must also be correspondingly farther separated from each other for the same reason.

It is apparent that if I prefer to use the form of tie having diverging side walls, as illustrated in my Patent No. 607,906, the yoke illustrated in Fig. 3 of my present application is admirably adapted to cooperate therewith.

In road-building the ties can be put down first and all the attachments put on afterward when the rails are put down. Still another advantage of this form of tie is that it may be used to take the place of wooden ties, and that when thus used. all that is necessary is to remove the wooden tie and place my me tallic tie in its place, as the metallic tie will just fill up the bed left by the wooden tie.

In Fig. 9 I have illustrated a modified form of securing-ear, which consists of the head 21, having the threaded aperture 22 and the integral and downwardly-extending threaded plug 23. When this form of ear is employed, the cross-tie is provided with the cooperating threaded aperture 24, adapted to receive the plugs 23 of the ears 21, as clearly illustrated in Fig. 10. The cooperating apertures 24 in the cross-ties are just sufficiently removed from each other to permit the ears when screwed home therein to receive the base of a rail between them. When the rail is thus received between said ears, it locks them in position; The threaded aperture 22 in the ears are adapted to cooperate with the bolt 6,

Fig. 6, in rigidly securing the rails in operative position. i

In Figs. 12 and 13 I have illustrated still another method of providing ears adapted to cooperate with the conical bolts in securing the rails in position on the cross-ties. In this instance the ears or lugs 26 are struck up wardly from the top section of the cross-tie, with which they form an integral part. Of course it is apparent that in cases when it is desirable to use the bridge-plate the ears or lugs may be struck upwardly therefrom, as illustrated in Fig. 14-, in the same manner that they are struck from the top section of the cross-ties.

It is thought that the form of tie and securing-ears illustrated in Figs. 10 and 12, on ac* count of their simplicity and the rapidity with which they can be taken up and put down, will be found specially serviceable in the construction of temporary roads used in connection with mining, &c.

Having thus fully disclosed the principles of my invention and shown means of applying the same to use, I yet do not wish to be limited to the exact showing made, but desire protection in all that comes clearly within the spirit and scope of my invention.
