RAIL-JQINT.

SPECIFICATION forming part of Letters Patent No. 694,134, dated February 25, 1902.

'Application filed November 16,1901. ASerial No. 82,546. (No model.)

To @ZZ whom, it Wray concern:

Beit known that I, JOSEPH L. CAMPBELL, a citizen of the United States of America, residing atButler,in the county ofButlerand State yof Pennsylvania, have invented certain new and useful Improvements in Rail-Joints, of which the following is a specificatiomreference being had therein to the accompanying drawings.

This invention relates to certain new and luseful improvements in metallic ties and fastenings for securing the rails thereto,and has for its main object to construct a cheap metallic tie and provide in connection therewith novel and effective means for securing the rails firmly in position upon the ties.

To this end the invention resides in the novel combination and arrangementof parts to be hereinafter more fully described, and specifically pointed out in the claims.

In describing the invention in detail refery'ence is had to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference indicate 'corresponding parts throughout the several views, in which- Figure 1 is a side elevation of a portion of iny improved tie and fastening device, showing the rails secured therein, the latter being in section. Fig. 2 is a top plan view of Fig. 3 is a top plan view of a portion of the tie with the rail and fastening device removed. Fig. 4 is a detail side elevaltion of the inside clamping-block. Fig. 5 is a like view of the out-side clamping-block. Fig. 6 is an underneath plan view of the inside clamping-block. Fig. 7 is a like view of the outside clamping-block. Fig. 8 is a detail perspective View of the pivoted lockingpawl for holding the inside clamping-block in position. Fig. 9 is an edge view of the same. Fig. 10 is a plan view of the securingkey for holding the outside clamping-block in position.

My improved tie is substantially in the form of an inverted T inv end view or crosssection, comprising a base 1 and a head 2. In its upper face this tie is recessed adjacent to each end thereof,where the rails 3 are adapted to rest, the recesses 4 5, extending across the head 2 at an angle, and the portions 6 of the tie betweeu'the recesses 4 and 5 being adapted to receive the base of .the rail 3. The rail 3 is securely locked in position on the tie by meansv of the outside clamping-block 7, which has a tongue 8, adapt-ed to fit in the groove 9, provided therefor in the head 2 of the tie. This clamping-block 7 carries integral studs or pins 10, which project outwardly from the flange 11, carried by the block 7, and are adapted to engage in apertures (not shownlwhich are provided therefor in the web of the rail 3. The clamping-block 7 has its inner edge 12 at an incline, this incline andthe bevel given thereto conforming to the angular wall of the portion 6, upon which the rail rests. The clamping-block 7 is held in position in the recess 5 by means of the key 14, which is inserted in the keyway l5, provided therefor in theunderneath face of the block 7 and in the head of the tie. This keyway extends at an angle across the block and tie, as shown. To engage the inner face of the rail-web, I provide a clamping-block 16, which has a tongue 17 on its outer end which engages in the groove 18, provided therefor in the head 2 of the tie. This block 16 also has a tongue 19, the outer face of which is at an angle to the block and which engages and conformsto the angular wall of the portions 6 of the tie. The tie is recessed underneath the block 16, and in this recess 2O is mounted a locking-pawl 21, which is secured upon a short shaft 22, that is journaled in the socket 23 in the tie. This locking-pawl 21 is provided with a keyway 24, which is in registration with the keyway 25, provided in the side of the tie and through which a suitable key 26 may be inserted for operating the locking-pawl so as to throw the same into a locked position, as shown in Fig. 1, or to operate the same so as to move the pawl within its recess and permit the removal of the clam ping-block 16.

, In practice the clamping-block 7 is placed in position and securely locked by its key 14 when the rail 3 is placed in position against said clamping-block, and the clamping-block 16 is then slid into the opening transversely of the tie, and after being adjusted to position the locking-pawl 21 is thrown upwardly into the recess 27, provided therefor in the IDO underneath face of the block 1G. To remove thereof at an angle, of a pair of clamping-' blocks fitted in said recesses and adapted to embrace opposite sides of the rail, pins carried by one of said clamping-blocks, a key for securing one of the blocks in position, and a.

pivoted locking-pawl for securing the other block in position, substantially as described.

2. In combination with a metallic tie having recesses in the upper face thereof, of a pair of clamping-blocks mounted in said recesses, a key for securing one of said clamping-blocks in position, and a pivoted lookin gpawl for securing the other of said, blocks, substantially as described.

3. In combination with a metallic tie, a pair of clamping-blocks adapted to embrace opposite sides of the rail for holdingsame to the tie, a key fitting in the angular keyway extending through one of the blocks and through the tie, and a locking-pawl mounted in the tie and adapted to engage in the recess in the other clamping-block for securing same in position, substantially as described.

4. In combination with a metallic tie having recesses in its upper face, of a pair of clamping-blocks tted in said recesses and provided with tongues which engage in grooves in the tie, a key for securing one of the blocks in position, and a pivoted lockingpawl mounted in the recesses of the tie and adapted to engage in the recess of the other clamping-block for secu ring same in position, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.
