To all whom it may concern.-

Be it known that we, LOUIS PHILIBERT GOFFIN and EVARISTE VANRIET, both residing at Brussels, in the Kingdom of Belgium, have invented certain new and useful Improve ments in Securing Ilailway-Rails to Metal Sleepers. (for which we have received Letters Patent of Belgium, dated September 24, 1886,

No. 74,626,) of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part thereof.

Our invention relates to a peculiar system of rail attachment for fixing railway-rails to metallic longitudinal or cross sleepers; and it consists of the use of an angularly-movable resting or bearing plate, A, in combination with two lock-pieces,l3 and G,and a wedge or key D. (See Figuresl and 3,which are respectively a sectional view on the line 1 2 of Fig. 2 and a sectional view on the line 1 2 3 4. of Fig. 4.) These different parts are arranged and combined in such a manner that when the resting or bearing plate A is placed under the rail-foot in a position parallel thereto, Figs. 1 and 2, one of its lock-holes, of oblong form, shall coincide with a similar opening in the sleeper and permit of the introduction of the outer lock-piece, B, which is then displaced until it is almost in contact with the end of the lock-hole. Then, by means of a lever, the sleeper and the resting-plate are ap plied against the lower surface of the rail. By then turning the resting-plate,by striking it with a hammer until it is in its normal position perpendicular to the rail, its angular motion is also imparted to the outer lock, B, which, by turning on its vertical axis, gradually and very tightly pinches the rail foot and can no longer be removed.

In thenormal position of the resting-plate A, indicated in Figs. 3 and 4., another hole in the same coincides with a corresponding hole in the sleeper situate 011 the inner side of the rail, and now permits of the forced introduction of the inner lock-piece, 0, whereby an energetic traction is exerted by means of the resting-plate A. on the externallock-piece,and the pinching action of the same is increased.

The inner lock-piece is then entirely secured in its position by driving a suitably-shaped key, 1), between the free part of its head and the restingplate until perfect fixing of the rail is effected.

The restingplate A, Fig. 3, may have a uniform'thiokness or a decreasing one, so as to present an inclined surface corresponding with the inclination to be given to the rails.

The outer lock-piece, 13, Figs. 3 and 5, resembles in its section a double headed bolt suitably shaped for adaptingitself to the shape of the rail-foot. Its upper head is enlarged, so as to offer a sufficient surface of contact. Its shank is at N, Fig. 5, of a section shown, Fig. 7,so asto permit of free motion inthe hole in the sleeper, and at M, Fig. 5, of a section shown, Fig. 6, so as to compel the lock-piece to follow the angular motion of the restingplate.

The inner lock-piece,0, Figs. 3 and 8,which may be replaced by any other contrivance or look, if desired, possesses a single head of special shape, so as to bear on one side against the rail-foot, whereas on the other side it leaves between it and the restingplate a certain opening for the reception of the key D. The shank of this inner lock-piece is bent at its lower end, so as to bear against the under surface of the sleeper. The upper heads of the lock-pieces are made hollow or grooved out, so as to resemble in their section a T, whereby their weight is diminished without diminishing their resistance.

The key D, Fig. 9, is straight or slightly inclined,and is wedgeshaped at one end and reenforced at the other. It is, moreover, provided with one or more ribs, which are engaged in corresponding slots in the lock-piece.

The arrangement described above permits of the rails being secured on the external side Without displacing the same, and on theinner side by the simple effect of the key.

When the rail ends are supported, lockpieces of larger dimensions may be employed at thejoints, so asto secure two abutting rail ends at the same time; or a lock-piece of greater dimensions may be used outside the rails, and two lock-pieces on the inner side, one for each rail driveninto holes conveniently spaced apart.

Having fully described our invention, what we desire to claim and secure by Letters Patentis-- 1. The railwaytie, perforated as described,

and an angularly-movable resting plate, A, provided with two lock-holes, in combination with two lock-pieces,B C,and a wedge or key, D, the arrangement being such that in the first position of the resting-plate, parallel to the rai1,one of its lock-holes corresponds with a similar opening in the sleeper, so as to permit of the introduction of the external lockpiece, 13, whereas in its second position, transverse to the rail, the other lock-hole coincides with a second opening in the sleeper, thus permitting the introduction of the inner lockpiece, O,substantially as described above, and shown in the annexed drawings.

2. The combination of the resting-plate A, with an external lock-piece, B, of such a section at N as will permit of its free motion in the opening of the sleeper and of such a section at M as will compel it to partake of the angular motion of the resting plate A, sub- 20 stantially as shown in the annexed drawings.

3. The combination of the resting-plate and the external lock-piece, B, with one or more lock-pieces, G, secured by means of a ribbed key, 1), and situate between the said key and 25 the rail, as specified.
