METAL frm.

Specification of Letters Patent.

Patented Jan. 5, 1909.

Application filed March 18, 1908. Serial No. 421,814.

T 0 all whom it may concern:

Be it known that I, BYRON C. MURRAY, a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented certain new and useful vImprovements in Metal Ties, 1of which the following is a specification.

The present invention relates to metallic ties and has specially in view a novel form of rail fastener having a `pivotal engagement with the tie and adapted to tightly lock the rails thereon.

With the above and many other objects in view, the invention contemplates the em v loyment of a metal tie preferably of the hol ow type, the end portions of which carry supporting means for pivotally mounted rail clamping members with each of which a cooperating wedging member is employed to cause said clamping members to rock to a position where they will clamp opposite sides of a rail to firmly hold the same to the tie.

In carrying out the invention changes may be made in the details of construction, a preferred and practical embodiment of which isv shown in the accompanying drawings, wherein Figure 1 is a perspective view of a rail tie equipped with the novel rail fasteners, the same being shown with a rail clamped in position at one end of the tie, the clamping members at the other end being omitted to better illustrate their supporting lugs. Fig. 2 is a longitudinal sectional view taken on the line 2 2, Fig. 1. Fig. 3 is a bottomplan view of the tie. Figs. 4, 5 and 6 are, respectively, a side elevation, plan, and end view of the wedge which cooperates with the clamping members.

Like characters of reference designate corres onding parts.

t is preferred to associate the present in-V vention with the form of hollow metallic tie shown more clearly in Fig. 1 of the drawings ribs 7--8, and a plurality of openings 9 ar-M ranged between each pair of ribs.

Each of the end pockets 1 and 2 is provided with diametrically oppositely located clamp supporting lugs 10-11 provided with an intermediate fiat upper surface 12 and u standing rounded end ears 1S-14, each o which is provided with a pivot opening 1515a. Said lugs are arranged as shown in Fig. 1 to permit of clamping members 16--17 being placed between them, said clamping members being each provided with a pivot opening 18--18L which register with the pivot openings in the said supporting lugs and through which the pivot bolts 19-20 are passed to effect a pivot engagement between the said lugs and clamping members. Said pivot bolts are provided with the nuts .21-22 at their ends to retain them in position. The said clamping members 1(517 in their general configuration are substantially duplicates, and referring more articularly to Fig. 2 of the drawings, it will e observed that each is provided with an inwardly projecting arm 23 which carries a clamping plate 24, the outline of which conforms to the outline of the top and bottom of the spiking iange a of the rail A. Said clamping plate 24 is preferably formed integral with the clamping members and its bottom is strengthened and supported by the inwardly horizontal flange 25, beneath which the major portion of each clamping member is cut away to form a longitudin( lly tapering wedge shaped locking recess 26, the inner wall 27 of which is beveled.

The clamping plate 24 carried by clamping member 16 is referably of a larger size than the plate carried by the clamping member 17, and its u per portion is of thesame configuration. as t .e web b of the rail A, with which it engages when in a clamping position. A locking wedge 28 cooperates with 1 the clamping members 16-17 to fasten the rail to the tie, said wedge being provided with an enlarged or laterally extending head portion 29, and longitudinally tapering,

transversely beveled sides 30-31, which correspond with the locking recesses 26 formed in the bottoms of the clamping member 16--17, and also with similarly shaped openings 3 1 a in the side walls of the tie which register with the said locking recesses.

To attach a rail to the tie, the same may be l slid through the clamping lates, which of course would be thrown bac on their pivots to permit of such passage of the rail. After the rail is in roper position, the locking wedge is assed through the opening 31a of the tie an its sides enter the locking recesses 26. Owing to the tapering formation of the wedge and the locking recesses, the continued driving in thereof will cause the clamping members to rock on their pivots, spreading apart the lower portions thereof and bring the clamping plate against the rail sides with sufficient pressure to retain the rail in an immovable position. The locking wedge is of such a length that when in its locked position its smaller end will project beyond the tie, and to assure the same being retained in a locking position, a plurality of key openings 32 are formed therethrough for the reception of a locking key or other suitable retaining means. Said key openings 32 are preferably arranged in a longitudinal row to permit of the Wedge being used in connection with ties of various widths.

From the foregoing description it will be seen that the present invention provides a rail fastening device which is capable of being placed in a rail locking position by driving the wedge in one direction through the tie and the clamping members, and owing to the reduced end of the wedge projecting beyond the opposite side of the tie, the saine may be readily forced in the opposite direction to cause the clamping members to release the rails. And it will be further observed that through the described arrangement of the flange 25 at the bottom of each clamping member, a support is provided for the rail at the center of tie pockets which serves to prevent any buckling or bending of l the rail.

The structure described herein can be adapted for insulated track service by sim ply mterposing insulated material I between the clamps 16 and 17 and the opposing surfaces of the rails as suggested in Fig. 2 of the drawings.

. Claims.

1.*A tie provided with supporting lugs, oppositely located rail clamps having a pivotal connection with said lugs, and a locking wedge cooperating with said clamps to cause them to engage with opposite sides of a rail.

2. A tie provided with supporting lugs having upstanding pivot ears, oppositely located rail clamps having a pivot-connection with said ears, and a locking wedge coperl i l l i l l i l l ating with said clamps to causethem to engage with opposite sides of a rail.

3. A tie rovided with supporting lugs, o positely llocated rail clamps carrying c amping plates which conform to the contour ofthe base of the rail and being provided with a lower locking recess, and a locking wedge coperating with the locking recess in each rail clamp to cause the said clamping plaltes to engage with opposite sides of the rai 4. A tie provided with supporting lugs, oppositely located rail clamps each carrying a rail gripping plate and being provided with a lower locking recess the side wall of which is beveled, and a locking wedge the sides of which correspond in shape with the said locking recesses and adapted to coperate therewith to cause the said clamps to engage with opposite sides of a rail.

5. A rail tie provided with end pockets, supporting lugs in said pockets and provided with upstanding end ears, rail clamp ing members having a ivotal connection with said ears, said rail c amps being oppositely mounted and each carrying a clamping plate which conforms to the outline of the base of the rail and being provided with a tapering bottom locking recess the end walls of which are beveled, and a locking wedge having longitudinally tapering transversely beveled sides which coperate with said locking recesses to rock said clamping members on their pivots and cause tneir clam ing plates to engage with the sides of a rail? 6. A rail tie provided with end pockets, supporting lugs in said pockets and provided with upstanding pivot ears, rail clamping members having a pivotal connection with said ears and each carrying a rail clamping plate and being provided with a bottom rail su porting flange and a locking recess, and a ocking wedge coperating with said locking recesses to rock said clamping members on their pivots and cause their clamping lates to engage with opposite sides of a rai In testimony whereof l hereunto afiX my signature in the presence of two witnesses.
