SPECIFICATION Aforming part of Letters Patent No. 539,210, dated May 14, 1895. Application had January 23,1595.V sein Nb. 535,895. (no mtas.)

T0 all whom it may concern.: Y Be it known that I, WILLIAM H. ADDIoKs, of the city of Philadelphia, State of Pennsylvania, have invented a certain new and useful Improvement in Metallic Railway-Ties, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that class ofvmetallic railway ties in which the tie is especially shaped for the purpose of securing the rails in position, its object being to provide a secure and economical construction of tie, which,in connection with auxiliary fastening devices of simple character, may be employed to hold the rails in place, as more fully set forth hereinafter. t In my improved construction herein described Ithe necessity for the employment of spikes, screws, dac., is obviated, and a firmer locking construction provided. In constructions where spikes, screws, dre., are employed they are always liable to Work loose under the vibrations consequent upon the passage of trains. The parts necessary to the complete construction of my invention herein described are reduced to a' minimum, and these parts are constructed so` as to be interchangeable and can be readily replaced. In this construction the line and gage of the rails so adjusted will be accurate and positive, and can be readily set into position without loss of time and labor, as for instance, not only in the original construction of the line but in case of accidental de'- struct-ion or derangement of the line.

In the accompanying drawings, Figure lis a sectional elevation on the lino 1 1, Fig. 2, of a railway-tie construct-ed lin accordance with my invention. Fig. 2 is a plan View of the same. Fig. 3 is a perspective view of the tie proper. Fig. 4 is a perspective view of one of the railfastening keys. Fig. 5 is a similar view illustrating a form of key and spacing-block which may be placed between f one of the rails and a guard-railat bridges,

face, extendingY longitudinally of the tie, and being interrupted or cut away at the points where the rails lie in order that the base of the rails may rest directly upon the broad 4upper surface of the main body of the tie, andbe secured thereon through the medium of the central rib. l

The rib, a', is cut awayand recessed at b to conform to the base'andfweb of one side of the rail, and at c is cut away at anangle, as shown more clearly in Fig. l. To one side of the base of each rail the upper surface of the ti'e is provided with a slot, d, extending preferably in a line parallel with the length of the rail.

The securing key, E, is formed of a block of metal of a thickness about equal to that of the rib, c', and on one side is so shaped as to conformv `to the contour, in cross-section, of one side of the baseand verticalweb of the rail, and: on the opposite side or end is cut away at an angle corresponding to the angle at which the rib, a', is cut at c, and is of a size to fill the space intervening between the end of the rib at c and the inner surface of the rail, to snugly fit therein and to hold the rail, laterally considered, rigidly in position. On one face of the key is secured a tongue, g, which may be bent around at a right angle `to .the length of the key, as shown in Fig. 4,

and when in position is adapted to enter an opening, h, formed in the rib, a', and then bent to lock the key in position. The base of the keyis provided with a tongue, e, the length of the tongue e, being somewhat less than the length of the slot, d, connected with the main body of the key by the shank, e', the latter at its central portion being provided with slightly curved walls forming an opening in which the shank or neck, e', of the key may readily turn.

In assembling the parts the rail is first laid n position on the tieand pressed against the portion, b, of the rib, a', and the key, E, is turned at a right angle to the length of the rib, a', and its tongue, e, is passed through the slot, d. The key being then turned it comes into alignment with, or practically forms a continuation of, the rib, ct. .This turning of the key causes one of its ends to come into contact with the web and base of the rail and its opposite end to pass under and in contact IOO with the portion, c, of the rib, a', while at the same time its tongue, g, will have passed through the opening, h, and can then be turned parallel with the rib, or given a slight twist, as shown in Fig. 2, in order to prevent its return. Vhen the key is in place it is prevented from turning by this bending or twisting of the tongue, g, and is prevented from rising by reason of the inclined face, c, of the rib, a', and its locking tongue, e, which has been passed through the slot, CZ, and then turned until it is ata right angle to such slot.

The surface of the walls, c, transverselyconsid ered, is at a right angle to the length of the tie. When, therefore, the key is locked with its inner end abutting against the surface, c, the liability to lateral displacement ofthe rails is positively provided against. The rails cannot spread owing to the outer portion of the rigid rib, a', and they cannot be forced inl wardly, as above stated, as the inner edge of the key, E, coinciding with the lines of the walls, c, against which it abuts, is held firmly by the inner portion of the rib, a', against any inward movement.

In Fig. G I have illustrated a modification of the invention in which the height of the rib, a', is materially reduced, and the fastening devices operate only on the base or lower flange of the rail, to be employed principally where lateral support is not especially olesired. v

Where a double, or guard rail, is used, as at curves, bridges, crossings, or switches, the outer rail is first placed in position against the specially shaped portion, h, of the rib, a', as shown to the right of Figs. l and 2. The upper surface of the main body of the tie is provided with a T-shaped slot, Z, Z, the por- 4 otion, Z, extending at a right angle to the length until it is in contact with the rail.

of the tie while the portion, Z', is formed immediately in line with the rib, d. rst,or outer rail, has been placedin position the base, m, of a spacing block or key, M, is passed through the portion, Z, of the slot,and the key is then moved up in the portion, Z',

The second rail is then placed in position,and locked as in the first instance with a key, E.

It will be noticed that the opposite ends of I the key or spacing block, M, are both shaped to conform to the contour of the sides of the main rail and the guard rail, so that both rails will be firmly clamped and held down in position on the tie.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination of the railway tie having on its upper surface a recessed rib one wall or edge of each recess being so shaped as to conform to the contour of one side of the web and base of a railway rail and the opposite wall or edge being inclined, there being in the upper surface of the main body of the tie a slot, as CZ, extending at an angle to the After the length of the tie, with a locking key having one end so shaped as to conform to the contour of one side of the base and web of therailway rail and its opposite end being inclined at an angle corresponding to the angular wall of the recess in said rib, a tongue formed integral with and extending parallel to tho length of the key, said tongue being adapted to enter the slot, 7L, and means for locking said key in position, substantially as specified.
