I To ad whom 'it may concer/a:

Ber it known that I, MINor'r A. G. STIL-v soN, a citizen of the United States, residing at lVat-erbury, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Railway- 'l`ies; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this ap plieation, and represent, in

Figure l a top or plan view of a railway tie constructed in accordance with my invention, shown with rails resting thereon. Fig. 2 a sideview of the same. Fig. 3 a longitudinal sectional view of one end of the tie. Fig. l a perspective view of one cf the wooden blocks detached.

This invention relates to an improvement in railway ties, and particularly to ties made of reinforced concrete, the object of the invention being to construct a tie which will be sufficiently strong to stand the necessary strain and which shall contain wooden blocks to which the rails are secured, which blocks may be removed, if necessary, when worn out; and the invention consists in the construction hereinafter described and particularly recited in the claims.

In constructing ties in'accordance with my invention, I locate wooden blocks 2 and 3 in a suitable mold by which they are firmly held. These blocks are rectangular in transverse section with side walls tapered inward from their lower edges to the top. These blocks are of snllicient depth to receive an ordinary rail spike, and the blocks are' preferably bored with four holes 4 to receive such spikes. As a rule, however, only two spikes are used at each tie,bnt by providinga block with four holes provision is made for shifting the spikes from one hole to another. These blocks are treated with any suitable Wood preservative and the holes bored in the block assist in allowing lhe preservative to saturate the block. Preferably the main grain 'of the wood block will run parallel with the length of the lie, but it is obvious that instead of employing;l wood blocks, wood liber or other material may be eniployedjwith equal success. 'lho molds in which the tio 5 is formed are provided with recesses in each side to form projections l and 7 on each side and also extensions 8 below` the bottom of the main portion of the tie. The upper edges of the projections 6 and 7 are in line with the lower faires of the blocks 2 land 3. These projections? andextenslons assist in holding the tie ,more iirmly in place in the roadbed and providea rigid bearing for the blocks. Extending longitudinally of the tie and near the bottom thereof, is what I will term the main reinforce 9 provided with depressed por tions 10 where it passes beneath the wooden,

blocks 2 and 3. Surrounding the two sides and bottom of each block is an auxiliary reinforce l1. These reinforces are preferably formed from scrap perforated metal, al-

though any other material may be employed.v The portion 12 of the auxiliaryy reinforce 1l passi-ng below the blocks is preferably laced or tied to the portion l0 of the main reinforce 9. In forming the tie these reinforces may be supported by spikes 14: driven at an angle through the upper portions of the reinforce 1l and into the wooden blocks as shown in Fig. 8 of the drawings. held in proper position with relation 'to the blocks until the mold hasbeen lled with concrete and the concrete has set. I may here state that preferably in the mixture of concrete I will employ cinders, and in, this way a lighter tie is produced. llhen the Lie is completed, the spikes 14 may be withdrawn if desired, although they will serve to hold the blocks in the tie. The bases l5 of the rails 16 rest upon the blocks 2 and 3 and are. secured by spikes i7 enten ing the holes t prepared forlthem. llhen it is desired to adjust the tie or insert-new blocks, it is only necessary to remove the 'spikes 17 and drive the blocks out of the tie and insertnew blocks therein. The rojections below the block provide a sufficient thickness of concrete below the blocks to properly support them and.' give requisite n length to the ties at these points.

lt will. be understood that the number of blocks in rted may be more or less accord-V ing` to the purposes for winch the tie is to be used, and the number of holes may also be variedc I claim i p i. A tie comprising wooden blocks hav ingtapered sides, said blocks located in a concrete body which body betweeiiuiits ends is formed with projections on oppositesides of but below said blocks beyond the endsiof In this way thereinforces are which they project, a main reinforce strip extending longitudinally of the tie and formed with bends below the blocks, and

Aauxiliary reinforces surrounding the sides and bottoms of the said blocks.

2. A tie comprising wooden blocks having tapered sides, said blocks located in a concrete body which body between its ends is formed'with projections on opposite sides of but below said olocks beyond the ends of which they project, a main reinforce strip extending longitudinally of the tie and formed with bends below the blocks, auxiliary reinforces surrounding the sides and bottoms of the said blocks, and spik'es extending diagonally through the auxiliary reinforce and into the said blocks.

3. A tie comprising wooden blocks having tapered sides, said blocks located in a concrete body formed with projections on opposite sides of but below 'said blocks beyond the ends of which they project, a main reinforcing strip extending longitudinally of the tie and formed with bends below the blocks, an auxiliary reinforce surrounding the sides and bottoms of said blocks, said auxiliary and main reinforces laced together below the said blocks. y

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
