ISAAC B. WALLACE, OF INDEPENDENCE, KANSAS.

RAILWAY-TIE FASTENER;

Specification of Letters Patent.

Application filed September 10, 1912.

. atented Sept. 2, 1913.

Serial No. 719,517.

'[b all whom, it may concern Be it known that I, ISAAC B. lVALmen, a citizen of the United. States, residing at Indcpcndence, in the county of .lVIontgomcry and State of Kansas, have invented certain new and useful Improvements in Railway- Tie Fasteners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to, make and use the same, relierence being bad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to a railway tie, and more particularly to a combination metal and concrete tie, theprineipal object of the invention being to provide a device oi. this character comprising a two-piece base member of concrete, or the like, a metal tie bar adapted for support on the base members, and means for connecting the metal tie with the base members, and with the rails, and thereby provide a substantial support and firm connection for the rails while eliminat ing the rigidity incident to the use of a continuous concrete tie.

It is also an object of the invention to provide connection for the metal and concrete tie parts which, While holding the parts permanently together, will allow one to cushion on the other and thereby still further obviate the rigidity above mentioned.

In accomplishing these objects, I have provided the improved details of structure hereinafter described and illustrated. in the accompanying drawings, wherein Figure I is a plan view of a railway tie constructed according to my invention, illustrating its application to a pair of rails. Fig. II is a central longitudinal section of same, showing the connections between the parts. Fig. III is a detail perspective of a metal tie and its anchoring studs.

.teterring more in detail to the parts '1. designates the concrete tie base which is formed in two sections, the inner ends of which are spaced to form independent members, although extending in transverse alinement relative to the track, and, except for the central spacing, being 011? substantially the same form and size of an ordinary railway tie. Each of the sections has a socket 2 in its upper face for receiving the shoe oil. a metal tie member and extending vertically through the section from the base of the socket is a dowmvardly converging tapered aperture 3, having vertical. grooves 3. A metal tie 4; is adapted to seat on the concrete base members 11. and has dmvnwardly oll'set heads 5 adapted to seat in the base sockets 2 and fit snugly therein, this metal member having its ends turned i'lpwardly and backwardly to :form the keeper flanges (i and pockets 7 for receiving the outer base flanges 01 the rails. Depmiding from the head 5, at each end of the metal tie, is a hollow stud 8 which is tapered to fit within the base apertures 23, and has wings 8 for seating within the socket grooves 3. At the lower end of each of the studs 8 is a lip 9 having an aperture 10 therein adapted for receiving a spring key 11, the stud being of such length that its lower end will terminate flush with the lower 'lace of the concrete base, and the lip 5) project there below, so that the key 11 may be set in the lip aperture and bear against the bottom of the base, it being apparent that by locking the parts together with the spring key the latter may yield slightly to allow the parts to cushion relative to each other. The inner edge of each of the metal tie heads 5 is inclined to receive the beveled edge of a chair plate 12 which is adapted to lie over the inner flange of the rail base and bears snugly against the inclined edge of the head. Each of the chair plates is apertured to receive a lag bolt 1.3 which projects through the aperture and is threaded into the hollow stud S in order to lock the chair plate to the rail base and hold the latter firmly to the tie. The parts describci'l are in duplicate at each end ()if the tie and consequently the detailed description ol such parts which has just been given relates equally to the parts at each end of the tie.

In using the device, the concrete tie sections, or bases, are arranged in longitudinal alinement in the road bed and the metal tics sealed thereon, with the anchoring studs projected through the base apertures, and the studs locked to the bases by the spring key to form an integral tie struclnre. 'lhe rails are then seated on the tie heads with the outer base llanges located within. the pockets 7, the chair plates applied to the rail base and tie head, and the lag bolls applied and tightened against the chair plates to firmly lock the plates to the rail base and tie head and rigidly anchor the rail to the tie.

It is apparent that with this construction an integral tie is aflorded which will not have the rigidity of a. continuous concrete tie, but which will hold the rails firmly to the tie, and in proper spaced relation. It is also apparent that the anchoring stud and lag bolt structure will take the place of the ordinary spikes and will not become loosened from the tie, as the bolt has a positive locking engagement with the stud and the latter is permanently anchored to a substantially indestructible base.

lVith the down set tie head a shoulder is formed against which the chair platemay abut, so that the plate may be held rigidly in place with but a single bolt, as the shoulder and .web of the rail will hold the plate against pivotal movement on the single bolt. Should it be necessary to remove a rail, the chair plate may be easily and quickly separated from the tie and replaced in the same position, as the threaded connection with the stud does not destroy the holding relation as would the removal of a spike from a wooden tie.

Having thus described my invention, what I claim as new therein and desire to secure by Letters-Patent, is

1. The combination with an apertured base, of a tie member, having studs projecting through the base, means for yieldingly anchoring said studs to the base, and means for holding rails on the tie.

2. The combination with a rigid base, having sockets in its upper face, a tie having down-set heads seated in said sockets, means for anchoring the tie to the base, chair plates, and means for attaching the chair plates to the tie. V

3. The combination with a rigid base having Vertical apertures, of a tie seated on said base and having a downwardly projecting hollow stud, said stud having an apertured lip at its lower end, a spring key projected through the aperture in said lip and adapted to bear against the bottom of the base, a chair plate, and a lag bolt projected through the chair plate and threaded into said stud, substantially as set forth.

4. The combination with a rigid base, having a grooved aperture therein, of a tie seated on the base and having a winged stud located within the base aperture and grooves, a key for holding the stud to the base, a chair plate, and means for holding the chair plate to the tie.

In testimony whereof I a'HiX my signature in presence of two witnesses.

ISAAC B. VVALLAOE.
