TRACK-FASTENING.

Specification of Letters Eatent.

Patented Sept. 18, 1906.

Application filed August 2, 1905. Serial No. 272,432.

To all whom it In/(1,1! concern.-

Be it known that LROBERTVVILSON TATE, a citizen of the United States of America, residing at Cary, in the county of Sharkey and State of Mississippi, have invented new and useful Improvements in Track-Fastenings, of which the following is a specification.

The invention relates to an improvement in ties and also-to means for securing the rails in position on the ties.

The main object of the present invention is the production of means adapted for use in connection with a metallic tie and designed to removably secure the r. ils thereon.

The invention in its preferred embodiment of details will be described in the following specification,- reference being had to the accompanying drawings, in which Figure 1 is a side elevation of the tie, illustrating particularly the fastening means, the rail being shown in section. Fig. 2 is a longitudinal section through the rail-tie, illustrating particularly the rail-securing means arranged within the tie. Fig. 3 is an end elevation of the tie, showing a portion of the rail connected thereto; and Fig. 4 is an enlarged sectional detail illustrating the means for securing a tight connection between the dogs and rail.

Referring to the drawings, my improved tie comprises a hollow rectangular body 1, preferably square in cross-section and approximately of the size of the usual tie. The tie of my construction may be of any thickness of material desired and is designed to be embedded within the track-ballast, as is usual in ties of this structure.

The fastening means which is secured in duplicate near the respective ends of the ties to engage and hold the rail comprises a bolt 2, arranged. transversely of the tie immediately beneath the rail-plane and terminally projecting beyond the edges of the tie. Centrally of the bolt 2 within the tie-body are pivotally mounted dogs 3 and 4, formed with hook ends 5, arranged to extend through slotted openings 6, formed in the upper wall of the tie. The dogs 3 and 4 are of such length as to project their hooked ends through the slots to engage the edges of the base-flange 7 of the rail, as clearly shown in Fig. 2. Each dog is formed with a transverse opening 8, so positioned that when the hook end 5 engages the base-flange of the rail the openings 8 are immediately above or in alinement with the upper surface of the tie and when in this position are designed to receive keys 9, passed through said openings and resting upon the upper surface of the tie to secure the dogs against independent movement.

The dog 3, which is the dog engaging the outer side of the rail, is terminally formed with an enlargement 10, extending transversely of the end of the dog and recessed at 11 in its free edge to receive a coil-spring 12, the extended end of which spring is designed to bear against the web of the rail immediately above the base-plate, wherebyto insure effectual holding and stability of the dogs in operation.

On the end of the bolt 2 beyond the tie are mounted two additional holding dogs or arms 13 14, being pivotally secured on the bolts and having upwardly-extending ends formed with hook-terminals 15, designed to overlie and snugly engage the base of the rail, as clearly shown in Fig. 1. The arms 13 and 14 are each provided with a projecting portion 16, extending below their pivota connections and preferably lateral thereof, each of the projections being formed in its free end with an opening 17', designed when the arms are in locking position to register with the openings 18, formed in the wall of the tie, said registering openings receiving bolts 19, whereby to prevent movement of said arms, as will be obvious.

It will thus be noted that in conjunction with my hollow metallic tie I have provided means for locking the rails to the ends of the tie, the securing means being in du licate for each rail and located in different p anes with relation to the tie, one of the securing means being positioned centrally of and within the tie-body and secured exteriorly of the tie-nut in close contact with one vertical wall thereof. The rails are thus secured at two different points with relation to each tie, insuring an efiective and lasting fastening means.

Having thus described the invention, what is claimed as new is 1. The combination with a hollow metallic tie, of means for securing the rail thereto, said means being in duplicate, one set being arranged centrally of the'tie and the other beyond the vertical wall of the tie.

2. The combination with a hollow metallic tie, of duplicate, means arranged at different vertical planes for securing the rail thereto,

said duplicate means being mounted on a single pivot-bolt transverse the tie.

3. The combination with a hollow metallic tie, of a shaft arranged transversely thereof, rail -seouring dogs mounted centrally upon said shaft within the body of the tie, and railsecuring arms mounted on said shaft beyond the body of the tie.

4. The combination with a hollow metallic tie, of a bolt arranged transversely near one end thereof, rail-securing dogs mounted on said bolt within, the body of the tie, means for securing said dogs in engagement with the rail, rail-securing arms mounted on said bolts beyond the body of the tie, and means for securing said arms in engagement with the rail.

5. The combination with a hollow tie, of a bolt arranged transversely,thereof, lockingdogs pivotally supported on the bolt and having hook ends projecting beyond the upper surface of the tie and designed to engage the rail-base, and: pins passed transversely through said dogs and bearing on the surface of the tie.

6. The combination with a hollow tie, of-a bolt arranged transversely thereof, dogs .the surface of the tie to engage shaft arranged mounted on said bolt and projecting through the baseflange of the rails, arms pivotally mounted on said bolt beyond the body of the tie and having hook ends to engage the rail-base, projections extending from said arms, and means for securing said projections to the rail-tie to lockthe arms in operative positions.

7. The combination with a hollow tie, ofa transversely thereof, dogs mounted on said bolt Within the body of the 'tie and having hook ends; to engage the railbase, means for lockingsaid dogs in operative position, one. ofthe dogs-being formed with an enlarged end, and a spring supported in said enlargement and adapted to bear against the rail-web when the dogs'are in operative position.

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

ROBERT WILSON TATE.
