Bolt-holes es and the tie being shown in cross-section; and d8 are also provided through the clamp Fig. 2, a vertical cross-section through a rail members E and D, respectively, the hole da 10o 5o and the parts constituting my invention, the being slightly larger than the other holes for tie being shown in longitudinal section and a reason which will later appear.

The under surface of the base-plate C may be provided with projecting ribs C', which are driven into the tie to hold the plate in the desired position.

A plate F, having shoulders fat each end and bolt-holes adjacent thereto, may be located on the under side of the tie to serve as a lock for the heads of the bolts.

My invention is applied as follows: The base-plate C is fixed upon the tie at t-he point where the rail is to be located, its position being determined by a gage, so that the shoulders c will properly position the base of the rail. Bolt-holes registering with the aperture c3 in the base-plate are then made through the tie, and the bolts G are passed through the openings in the locking-plate F, through the holes in the tie, and through the openings c3 in the base-plate C. The rail is then located upon the base-plate between the wedge c and shoulders c and between the bolts G, after which the clamp member D is placed above the wedge c, the inclined surface d thereof engaging the.surface of the wedge and the enlarged opening d3 surrounding the end of the bolt G which projects above the wedge. The other clamp member E is located above the raised portion c2, with its inclined under surface in contact with the base of the rail on the opposite side thereof from the clamp member D, the aperture e3 surrounding the end of the bolt Gwhich projects above the raised portion c2. The nuts g are then turned onto the screw-threaded ends of the bolts, the bolts being prevented from turning by the engagement of their heads with the anges f of the lockingplate. When the nut on the end of the bolt above the clamp memberD is turned toward the head of the bolt, said clamp member, owing to the engagement between its inclined under surface and the wedge c on the baseplate, is drawn downwardly and at the same time inwardly. This inward movement is permitted by the opening d3, which is slightly greater in diameter than the bolt. The second clamp member E when the nut on the bolt above itis turned toward the head of the bolt is rocked slightly upon the raised portion c2 as a fulcrum, and thereby forced into close engagement with the upper surface of the base of the rail.

It is evident from the foregoing description of the manner in which my invention is applied that a rail may be readily and securely fastened to a tie without the use of nails or spikes, the base on one side of the rail being securely held between the clamp member E and the base-plate C, while the base of the rail on the opposite side is not only securely held against the base-plate, but is also forced laterally into engagement with the shoulders c', thereby accurately positioning the rail upon the tie.

While I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form, the proportion of parts, and the substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit of my invention.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a device of the character described, the combination with a base-plate having a shoulder and a wedge gradually rising from the plate at a point distant from said shoulder substantially equal to the width of the base of a rail, of a clamp having an inclined portion engaging said wedge and a vertical shoulder rising from said inclined portion adapted to engage the base of a rail, and means for drawing,r said clamp toward said base-plate thereby forcing the base of the rail against said shoulder and also securing the rail to the base-plate, substantially as described.

2. In a device of the character described, the combination with a tie, of a base-plate having a shoulder and a wedge spaced apart a distance substantially equal to the width of the base of a rail, of a clamp having an inclined portion engaging said wedge and a vertical shoulder rising from said inclined portion adapted to engage the base of a rail, and a bolt passing through said tie and baseplate and also through an enlarged opening in the inclined portion of said clamp, substantially as described.

3. In a device of the character described, the combination with a base-plate having a shoulder and a gradually-inclined wedge on its upper surface, of a clamp having an inclined portion extending from one side thereof to approximately its center engaging said wedge and a vertical shoulder rising from the central edge of said inclined portion adapted to engage the edge and top of the base of a rail, and means for drawing said clamp toward said base-plate whereby the base of the rail is forced against said shoulder and also secured to the baseplate, substantially as described.

4. In a device of the character described, the combination with a base-plate having a shoulder and wedge on its upper surface, of a clamp having an inclined portion engaging said wedge and a shoulder adapted to engage the edge and top of the base of a rail, a sec-y ond clamp adapted to engage the top of the base on the opposite side of the rail from the first clamp, and bolts passing through said base-plate and clamps whereby the base of the rail is forced against said shoulder and also secured to the base-plate, substantially as described.

5. The combination with a tie, a rail supported thereon, a shoulder projecting above the tie with which an edge of the rail-base engages, a gradually-inclined wedge also projecting above the tie at a distance from said shoulder substantially equal to the Width of IOO IlO

the rail-base, a clamp having an inclined portion extending from one side thereof to approximately its center engaging said wedge and a vertical shoulder rising from the central edge of said inclined portion engaging the edge of a rail-base, and means for securing said shoulder and wedge to said tie and coincidently forcing said clamp through its engagement With said Wedge against the edge and top of the rail-base, substantially as described. n

6. The combination with a tie, of a rail supported thereon, a base-plate having a shoulder and a Wedge projecting from the upper surface thereof, of a clamp-plate having an inclined portion engaging said Wedge and a shoulder engaging the edge and top of the rail-base, a second clamp engaging the top of the rail-base adjacent to said shoulder-,and

`bolts passing through said tie, base-plate, and

clamps,whereby the rail-base is forced against said shoulder and together with said baseplate secured to the tie, substantially as de,
