t relative movement.

It is a further object to obtain a simple and inexpensive construction.

The invention therefore consists in the= construction as hereinafter set forth.

In the drawings-Figure l is a side elevation of a rail joint to which my improvement is applied: Fin'. 2 is a cross section on lim` www, Fig. l; end view showing,y a modified construction` and Fig. is a perspective view of one of l t by the nut P. This clampingr will force the the clamping plates.

The standard construction of rail joints is one in which the adjonnng,- end portions 'of the railsw-such as A A', are clamped toi gether by fish plates B B secured by clamping bolts C. It is also usual to 'provide these fish plates with bottom flanges D which extend over the base portion E of the, rail. M v improved clamp is applicable to such a joint without the necessity of removing the fish plates, and is constructed as follows: F

I, Encan Gool), a citizen Fig. 3 is a broken i l l l l may be brought to .and F are two members arranged upon opposite sides of the rail and each provided l with a hooked flange or jaw G for engaging the flanges D of the fish plates and the base F. of the rail. further provided with inwardly-projecting portions II II.wliich extend into proximity to each other at substantially the center of the base of the rail. The portions II I-I are provided with grooved channels for receiving a wedge member or key I which extends transversely beneath the joint between the rails.

further provided with downward projections J J which are spaced from each other by means of integral inwardly-extending and abutting lugs K Killustrated in Fig. 3-or preferably by the spacer If-shown in Fig. 2-the opposite ends of which are These members F F are The sections F F' are still recessed ,to engage lugs M M 4on the portions J J. This latter construction permits yof applying the device to various widths of rail by merely exchanging the spacer for one of different length. The members F F are clamped to each other by transversely-extending clamping bolts N N, and the Wedge or key member I is clamped by a bolt O, which extends at an angle to the longitudinal axis of the' wedge, and en-v gages apertures in the wedge and the member F. Thehead ofthe bolt preferably engages a recess in the large end of the wedge, j

while the threaded'end of the bolt projects outward beyond theside of the member F and is engaged by a clamping nut I.

With the construction as described, to apply the clamp to the rail joint, it is merely necessary to placethe members F F upon opposite sides of the rail with the spacer L and then insert and secure therebetween. the bolts N N. After this, the wedge I. which is in its lcrooved scat in the portions H l-I, may be tightened by the insertion of thc bolt O and the drawing up of the bolt upper face ofthe wedge against the adjacent end portions of the rails, the force reacting againsty the hooked portions G `on the members F F. Thus sufficient pressure bear to absolutely hold the rail sections from relative movement.

My construction has the advantage that. while'the rails are held at all times with their abutting ends at precisely the same height, freedom is still provided for the rails to expand or contract. The vibration and pressure of a load on top of the rails will be distributed over the entire surface of the wedge which comes in contact with the entire width of the rail atthe under side of the rail foot,V Tipping or turning' of the rail is prevented" by the engagement. of the hooks or jaws with the rail base in connection with the clamping action of the wedge, and the engagement of said jaws with the flanges of the fish plates, which prevents the latter from becoming loose.

wWhat I claim as my invention is:

1. The combination with adjoining rail sections, of a pair of members upon opposite sides of said rail sections having chair bearings extending inward beneath thc rail base and downward projections, a strut for spacing said downward projections. a clamping bolt between said strut and the rail base, and a wedge seated on said chair bearings and engaging the bottoni face of the adjoining rail sections. 4

The combination with adjoining rail Seetons, of a pair of members upon opposite sides of said rail sections provided with chair bearings extending inward beneath the. rail base and downward projections, a

strut for spacing said downward projections, k a clamping bolt between said strut and the rail base, a wedge seated on said chair bearings, and a bolt'for adjusting said wedge to clamp the same against the bottom faces of the adjoining rail sections.

3. The combination with adjoining rail sections, of a pair of clampin plates upon opposite sides of said rail sections and having chair bearings extending beneath the rail base, a wedge seated on said. chair bearings and bearing against the bottom faces of the adjolnlng rail sections, and a bolt y extending at an angle to the axis of the l l i wedge for clamping the latter against the rail.

4L. The combination with adjoining rail sections, of a pair of members arranged upon opposite sides of said rail sections,

having grooved chair bearings extending beneath the rail base, j grooved bearlngs and bea-ring against the under face of the adjoining rail sections, a

bolt engaging the head of said wedge and extending at an angle to the axis thereof through an aperture in the opposite side member, and a nut for clamping said bolt.

5. The combination with adjoining' rail sections, fish plates upon opposite sides of said rail sections, having anges extending over the base of the rail, a pair of members upon opposite sides of said rail sections, jaws for engaging the anges of said fish plates, chair bearings extending beneath the base of the rail and downward projections, a strut for spacing said downward projections, a clamping .bolt between said strut and the base of` a wedge seated in said
