RAILROAD GRdSS-TIE AND JOINT-CLAMP.

Specification of Letters Patent.

Application filed December 27, 1911. Serial No. 668,029.

To all ivhomt it may b iiccrn:

Be it known that I, DANIEL J. McPnnR- SON, a citizen of the United States, residing at Cheraw, in the county of Chestorlicld and State of South Carolina, have invented a new and useful Improvement in Railroad Gross-Ties and Joint-Clamps, of which the following is a specification.

This invention relates to a railroad tie and joint clamp the. object of the invention is to secure the rails upon b .h sides of the track in place by means of i single bolt to prevent spreading of the rails and also the ongitudinal creeping of the tie, and a still further object of the invention is to' utilize the principle of oppositely operating wedges for the purpose of forcing a movable portion of the clamping devices into engagement with the rails thus holding them firmly between said movable portions and fixed clamping members integral with the tie.

In carrying outthe invention I employ the novel features of construction hereinafter described, pointed out in the claims and shown in the accompanying. drawings, in which: I

Fi ure 1 is a side elevation'of a tie with the clamping members, rails being shown in section. Fig. 2 is a plan view, the ball portions of the rails. being partly broken away and the rail webs being shown in section. Fig. 3 is a section on the line 3--3 of Fig.2.

' Fig. 4: is a fragmentary side elevation illus trating the construction of the clamping plates and operating wedges.

In these drawings 1 represents a metal tie having a flat uppersurface upon which rest rails 2. This the has its greater" thickness midway its ends the under surface of the tie sloping upwardlyfrom said central point to points adjacent the ends, which points are beyond the outer faces of the rails. The

' extreme end portions 3 of the tie are then angled and extend downwardly and outwardly, these end' poi'tions being the thinnest portions of the tie and practically forming end flanges extending obliquely with respect to theupper surfaces of the tie; Th s construction practically forms a. cavitynpon each side of the center of the tie ill.- which packed and effectually prevents any longiinncr ends the flanges 3 are carried inwardly to overhang the tie and are-then bent up wardly thus forming an angled chair or locking plate 4 beneath which the outer base of the rail is adapted tofit and prevents any spreading ofthe rails in the direction of the flanges 3. Slidably mounted upon the tie guide lugs 6 carried by the sides of the tie as shown at 7 to form a second chair or plate, the plates 7 engaging the inner sides tion. In order'to force the plates 5 toward the rails and lock them in osition, each plate has its inner end longitudinally recessed and between these plates work sub- The sides of the wedge s a d blocks are rounded to fit the recesses in the ends-.of the plates. along the tie in a straight line without giving to them any vertical movement.

A bolt 9 passes through these blocks trans: versely-to the tie upon which work suitable nuts 10, the blocks 8 will be forced together thereby forcing theplates 2 apart and into engagement with the rails. a

What I claim is:

the tie, plates slidably hel beneath said wedge shaped blocks arranged between the end portions of the last mentioned plates and adapted to force them in opposite directions 11 on movement of said 'Qlocks toward each at or.
