UNITED STATES PATENT OFFICE.

RAIL CHAIR.

Application filed March 9, 1921.

To all whom it may concern.

Be it known that I, ABRAHAM VAN ZILn, a citizen of the United States, and a resident of Long Beach, in the county of Los Angeles'and State of California, have invented a new and Improved Rail Chair, of which the following is a full, clear, and exact deseription.

My invention relates to a chair for railway rails and has for its general object to provide a rail chair so formed that when spiked to the tie and engaging the rail, it will afford resistance to the creeping or running of the rail and to the spreading of the rails.

More specifically, the invention has in view to provide a particular embodiment of the invention reflecting practical considerations with respect to strength and simplicity as well as looking to the convenient installation of the chair.

Reference is to be had to the accompanying drawing forming a part of this specification, it being understood that the drawing is merely illustrative of one example of the invention.

Figure 1 is a perspective view of a rail chair embodying my invention.

Figure 2 is a plan view thereof showing the rail in position and spiked to a tie, a section of rail engaged by the chair being also shown.

Figure 3 is a transverse vertical section as indicated by the line 33 of Figure 2.

In carrying out my invention in practice, my improve-d chair is made with a base plate 10 which. advantageously may be approximately oval shape. On the base 10 at the upper surface are integral longitudinal ribs 11 spaced to accommodate snugly tnerebetween the base of arail A.v Also, in practice. the ribs 11 are braced by transverse r bs 12 intergral therewith and tapering toward their outer ends, said transverse ribs being disposed approximately central of the chair.

On the ribs 11 are formed integral lugs 13 extending laterally inward from the planes of said ribs, said lugs 13, in practice, being accommodated in lateral recesses a which I produce in the base of the rail A at the opposite side edges thereof. The pro- Specification of Letters Patent.

Serial No. 451,051.

vision of the lugs 13 to thus enter recesses in the rail serves to effect an interlocking engagement between the rail and chair in a manner effective with a view to prevent creeping of the rail in addition to the functions of the spikes.

In the ribs 11 are formed transverse notches 14; and said notches are in register with or complementary to vertical holes 15 formed in the chair and adapted for receiving spikes B. The arrangement is such that the heads of the spikes B driven through the holes 15 are snugly accommodated in said notches and overlap the rail flanges, the arrangement contributing to withstand both creeping and spreading tendency of the rail. The notches 14, spike holes 15 and rail engaging members 13 are located between the transverse ribs 12 and the front and rear edges respectively of the base 10.

To "further provide against the displacement of the chair, I form on the base 10 at the under side, rigid depending lugs 1.6, preferably cylindrical and hollow, said lugs being receivable in corresponding holes formed in the railway tie C. The lugs 16 are disposed directly beneath the transverse ribs 12 that said ribs and lugs may jointly contribute. to strengthening tl e chair.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention. I do not limit myself strictly to the minor details herein illustrated. since manifestly the same -an be considerably varied without departure from the spirit of the invent-ion as delined in the appended claim:

I claim: a

As a new article oi manu'l'zu'ture, a rail chair having longitudinal ribs thereon spaced to accommodate a rail base thcrebctween, transverse strengtheni11;; ribs integral with the first ribs at the approximate center of the chair and ribs, and rigid depending lugs on the chair directly beneath said transverse ribs, said chair 'lt'urtherinore having rail engaging members between the planes of the transverse ribs and the front and rear edges of the chair and spike holes between said members and said ribs.

ABRAHAM VAN ZILE.
