amwwbmd Mfl, Ear re ZZ BanZ'J'cZd? Patented Sept. 2, 1930 UNITED STATES PATENT OFFICE WILLIAM R. GORRELL, F ALHAMBRA, AND HENRY BARKSOHAT, 01: LOS ANGELES, CALIFORNIA RAIL-ANCHORING MEANS OR SPIKE LOCK Application filed September 19, 1929. Serial No. 393,639i.

The invention relates to rail anchors or spike locks of a known type embodying two vertically elongated blocks adapted to be spread, by driving of a spike between them,

6 into tight engagement with opposite walls of an opening in a tie, rail or other support, and the present disclosure is also related to such a device in which a chair plate is provided to contact with the base of the rail, said chair plate having an opening receiving the upper ends of the aforesaid blocks.

It is one object of the invention to provide the outer sides of the blocks with ribs of unique form adapted to embed into the opposite walls of the receiving opening for said blocks when the latter are spread by driving of the spike between them.

It is another aim of the invention to pro vide novel means for holding the lower ends 0 of the blocks against excessive spreading.

Yet another aim is to provide unique means for securing the upper ends of the blocks to the chair plate upon spreading of said blocks by the spike, thereby preventing upward 25 movement of the chair plate by means other than the mere head of the spike.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawing.

Fig. 1 is a vertical sectional view showing the improved rail anchoring means.

Fig. 2 is a top plan view partly broken away and in section, only one of the spikes being in place in both Figs. 1 and 2.

Fig. 3 is a perspective view of the two blocks in juxtaposition.

Fig. 4 is a perspective view showing said blocks in assembled relation.

Fig. 5 is a perspective view of the yoke plate which holds the lower ends of the blocks against excessive spreading.

Fig. 6 is a perspective view of one end of 4 the chair plate.

Fig. 7 is a view similar to Fig. 4 showing blocks of different shape.

The construction herein illustrated may be considered as referred and while such construction will be specifically explained, it is to be understood that within the scope of the invention as claimed, minor variations may be made.

9 of wood or other preferred material. The ends of the chair plate 7 are formed with rectangular or round openings 10 and vertically elongated openings 11 are formed in thetie 9 for alinement with said openings 10.

Novel anchoring means is associated with each opening 10 and the subjacent opening 11 and since both of said means are duplicates, only one will be described in detail.

The numeral 12 denotes two verticallyelongated metal blocks for reception in the opening 11 to be spread into tight contact with opposite walls of said opening by driving of a spike 13 between said blocks, the inner sides of the latter being somewhat channeled to guide the spike and having appropriate opposed concave and convex portions 14-15 which distort the spike as shown in Fig. 1 and prevent it from being easily pulled out. The two blocks 12 may jointly provide asubstan tially rectangular structure as in Fig. 4 or a substintially cylindrical structure as seen in Fig.

Formed integrally with the outer sides of the blocks 12, are two U-shaped ribs 16, one .r;

rib being on each block. These ribs are adapted, upon spreading of the blocks by driving of the spike 13, to embed in opposite walls of the opening 11, thereby providing such a connection between blocks 12 and tie 9 as to securely anchor said blocks against withdrawal from said opening 11, acting like a wedge.

The upper ends 17 of the blocks 12 are reduced and received in the opening 10, shoulders 18 being formed at the lower ends of the reduced portions 17 to abut the lower side of the chair plate 7. The outer sides of these reduced portions 17 are provided with downwardly converging bevels l9, and the opposite ends of the opening 10 are similarly beveled at 20. Thus, when the blocks 12 are spread by the spike 13, an effective interlock is provided between said blocks and the chair plate 7. The blocks being firmly anchored in the opening 11 cannot shift upwardly and in A flat chair plate 7 is provided to support the conventional rail 8 and to lie upon a tie view of the fact that the plate 7 is efiectively locked to said blocks, it also is held against upward shifting by this means in addition to the head of the spike 13, lying upon the base of the rail 8.

The lower ends 21 of the blocks 12 are reduced and shoulders 22 are formed at the upper nds of these reduced portions. The portions 21 are received in an opening 23 in a yoke plate 24, which plate abuts the shoulders 22. This construction serves to hold the lower ends of the blocks 12 against excessive spreading and insures tight ancho age of the spike 13 between said blocks.

.Ve preferably provide the chair plate 7 with a shoulder 25 to abut the outer edge of the rail base. Hence, any tendency of the rail to shift outwardly under the thrust of th wheel flanges, has a corresponding ten dency to shift the entire chair plate 7, but as this chair plate is locked to both of the anchoring devices, the strain is distributed to both of said devices and shifting of the chair plate is positively prevented, the device being therefore much more ellicient than when outward force exerted against the rail, is resisted only by pressure against one spike or anchoring device.

The construction shown and described is simple and inexpensive, yet highly E'iIlClGIlt and as above stated may be considered as preferred, with the understanding that within the scope of the invention as claimed, variations may be made.

We claim 1. In a rail anchor enibmlying two blocks for reception in an opening of a rail support, whereby driving of a spike between said blocks will spread them into tight contact with the wall of the opening; a U-shaped rib on the outer side of each block adapted to embed in said wall.

2. In a rail anchor embodying two blocks for reception in an opening of a rail support, whereby driving of a spike between said blocks will spread them into tight contact with the wall of the opening; a yoke plate to prevent excessive spreading of said blocks at their lower ends, said yoke plate being apertured to receive lower end portions of said blocks.

3. In a rail anchor embodying two blocks for reception in an opening of a rail support, whereby driving of a spike between said blocks will spread them into tight contact with the wall of the opening; reduced portions at the lower ends of said blocks, shoulders at the upper ends of said reduced portions, and a yoke plate to prevent excessive spreading of said lower block ends, said yoke plate having an opening receiving said reduced portions and abutting said shoulders.

t. In a rail anchor embodying a chair plate to rest upon a tie, said plate having an opening, and two vertically elongated spikespread blocks for reception in an opening of the tie, the upper ends of said blocks being received in said opening of said plate; inter engaging formations on said blocks and plate t l in said ate and bl-:, cks ag: inst rela i movement upon spreading of by driving of the spike between said ks them.

5. In a rail anchor embodying a chair plate to rest upon a tie, said plate having an opening, and two vertically elongated spikespread blocks for reception in an opening of the tie, the upper ends of said blocks being received in said opening of said plate; opposed downwardly converging bevels on the plate at the ends of said opening thereof, and similarly converging bevels at the outer sides of said upper block ends, said bevels of the blocks being adapted to engage those of the plate upon spreading of the blocks by driving of a spike between them, thereby locking blocks and plate against relative vertical movement.

6. In a rail anchor embodying a chair plate to rest upon a tie, said plate having an opening, and two vertically elongated spikespread blocks for reception in an opening of the tie, the upper ends of said blocks being received in said opening of said plate; interengaging torn'iations on said blocks and plate for locking said plate and blocks against relaive vertical movement upon spreading of said blocks by driving of the spike between them, and a yoke plate apertured to receive the lower ends of said blocks to limit spreading thereof by the spike.

In testimony whereof we have hereunto aiiixed our signatures.
