Application nied October 28,

To 'all whom .fit may concern.'

.Be it known that I, LoTrrAR S'rorn, a citizen of the United States, residing at Cleve land, in the county vof Cuyahoga and State of Ohio, have invented certain new and useful Improvement in Railway Ties :and .Rail- Securing Means, of which the following lis a specification.

This invention relates to .railway ties, particularly ties composed chiefly of reinforced concrete or similar materials.

It has as one of its chief objects the pro* vision lof a reinforced `concrete railway tie which is characterized 'as being relatively light as compared with ties of similar composition, and sufficiently strong and resilient to withstand severe service condition-s without breakage.

Another object is to construct a concrete tie upon which the rails may directly rest and to which they may be adjustably secured.

A further object is to construct a reinforced concrete railway tie provided with means embedded in the tie and substantially flush with the top surface thereof for securing a rail in direct contact with the top surface of the tie.

A ystill .further object is :to provide means insertable in a tie composed 'of concrete or similar material for adjustably :securing a rail thereto.

Other objects will appear and be pointed out in the appended specification.

In `the drawings attached and forming a part of this speciiication- Figure 1 is a perspective view of a tie embodying my invention and assembled with two rails.

Figure 2 is a longitudinal :section taken on line 2-2 of Fig. 1.

Figures 3 and el are, respectively, transverse sectional views taken on lines 3 3 and 4% of Fig. l.

Figure 5 is an enlarged, longitudinal, sectional view of the rail securing mea-ns as-y sembled with a rail.

Figures 6 and 7 are, respectively, top plan and .longitudinal sectional views of a modified form of rail securing means.

The present embodiment of :my invention comprises a tie 1 composed of concrete or similar material 2 having a longitudinally extending cavity 3 in `the interior thereof and within a metal-lic reinforcing means 4, preferably wire netting, box shape with Vposition a rail 14: contacts with 1924. Serial No. 745,317'.

closed ends and with depressions 5 formed in lthe vtop thereof adgacent either `end of the tie. yThe .reinforcing means or netting, :is

spaced approximately an equal distance v00 from the top, bottom, sides and ends 'ofthe tie 1. In a tie .for a standard gauge railroad I have found it satisfactory to space the netting about .1 inch Afrom each face of the :ti-e.

The cavity/lf3 .may be formed conveniently 05 by a lsliell 6 of stiff paper 4or sheet metal, which is placed in the desired position during the Ymanufacture of the tie.

In the top 'of the tie 1 are located one or more sets of rail securing means. Each set comprises an insert 8 embedded in the tie and one or more railclamps 9 secured thereto by securing ineans l0. The inserts -8V which are preferably composed of metal .are elongated members .havin-g flanges 11 depending divergingly from the bottom thereof. Each insert has a recess l2 and a :slot 13 enlarged at either end and ei;- tending therefrom through the top wall of the insert. sert 8 and flanges ll are vinclined substantially yas shown 4they serve as means for locking the insert securely in position .in the tie 1. The insert 8 is of such -s'ize thaty itprojects into depressions 5 in the rei-nforc- 85 ing material L but is spaced apart therefrom when its top surface is substantially flush with the top surfaceV of the tie 1.. lnsuch the top of the member top of 'tie 1. The rail clamps 9 each vhave an .inclined portion to engage with the to-p surface of the base of a rail 14 and a portion having serra-tions 15 on its under surface to engage with corresponding serrations 15 ex- 95 tending 'transversely of insert .8. VAny suitable means may be used to hold clamp 9 and insert 8in assembled position such vfor fer:- ample as a headed bolt l0 insertable through the enlarged Send 16 lof slot cess l2 with the head of the bolt engaging the top wall of recess 12. g

In Figs. 6 and 7 I have shown a slightly modified form of my invention in which 17 designates aninsert .similar in .substantiallyY 105 all respects to insert 8 except that instead of having a clamp 9 on either side of rail 12, one end of then insert is formed with an in'- tegral upwardly extending projection 18 formed to engage with the top surface of a no rail base. lith such an insert only a single clamp v91s required to hold a rail in aslongitudinal l/Vhen the sides and ends vof .-in- S0 8 and also rests directly on the 90 13 .to slide in re- 100 Cil sembled position with insert 17, the projection 18 taking the place of the other clamp 9, shown in Fig. 5.

ln constructing a tie embodying my invention I provide a mold consisting of bottom and sides corresponding to the top surface and sides and ends of tie 1. Members 8 are placed with the top surface thereof on the bottom of the mold .and then the reinforcing material, for example suitably formed wire netting 4, is supported in the mold by suitable wire or sheet metal supports (not shown) and finally a shell 6 is similarly supported within the netting 4. A mixture of sand, cement and water, with or without other suitable materials for making strong concrete, is then brought into the mold and caused to fill completely the mold both Within and without the netting 4. It will be understood that with sufficiently fine material having the necessary fluidity this may be easily accomplished since it will readily iow through the netting and into the various angles and corners of the mold without difficulty. After the material has dried or become suthciently hard to retain its shape the mold may be withdrawn.

The cavity 3 in the tie not only lightens the tie, as compared with other concrete ties, but also appears to affect advantageously the property of the tie to resist severe shocks and seems to confer considerable resiliency upon the concrete structure. Inasmuch as the rail rests directly upon the top surface of the tie, the weight of a. car passing over the rail is transmitted to substantially the entire width of the tie and absorbed thereby, the inserts S or 17 thus serving merely as rail securing means and not as the main support for the rail. Although the cavity 3 is shown in Fig. 2 as being of substantially the same cross sectional dimensions throughout its length it may be enlarged between the inserts 8, or in other parts, if desired, and the structure still further lightened thereby.

Although I have shown my invention embodied in a single tie for both rails of a railroad it will be understood that a tie einbodying my invention may be used with securing means for a single rail and with one rail only.

It will be understood that insert 8 possesses the advantage that a rail may be shifted back and forth on the tie and secured in any desired position for the purpose of suitably aligning two rails or for changing the track from one gauge to another.

Having thus described my invention so that those skilled in the art may be enabled to practice the same, what I desire to secure by Letters Patent is defined in what is claimed, it being understood that the various details herein illustrated and described are for the purposes of setting forth my invention and are not intended to define the scope of my invention.
