METAL BEENFOBGED-GOITCRETE R'AXLWAY TIE.

Application filed August 8, 1924. Serial No. 7311,8-79.

Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Metal Reenforced-Concrete Railway Ties; and I do hereby declare thetfollowing to be a full, clear, and kexact description of thel invention, such as will enable others skilled in the art to which it appertains to make and usethe saine. l

My present invention has for its object to provide a strong, durable, and highlyefticient metal reenforced concrete railway tie, and to this end it'consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings: y

Fig. 2 is a longitudinal section taken on the line 2 2 of Fig. 1;

Fig. 3 is a horizontal section taken on the line 3 3 of Fig. 2;

Fig. 4 is a View partly in 'elevation and partly in transverse vertical section taken on the line 4 4 of Fig. 2, on an enlarged' scale;

Fig. 6'is a detail view principally in section taken on the line 6 6 of Fig. 1, on an enlarged scale; and

Fig. 7 is a detail view partly in plan" andl f of these tie bars 10 are extended outward partly in section taken on the line7 7 o Fig. (-3. y

rEhe numeral 8 indicates the concrete body of a railway tie, and the numeral9 k indicates sections of a pair of rails supported thereon. VEmbedded in the body 8 is :a metal reinforcement comprising a pair of parallel longitudinal tie bars Y10, a pair oftie bars 11, a truss rod 12,anda reinforcement 18 of expandedmetal. The' parallel end tie bars 10 and 11 are inyoblique arrangement with the ends of the tie bars 11 resting on the tie bars 10, and which tie bars are thusV connected .by four upright sleeves 14 which extend through aligned bores therein. v l

The end bars 11`are turned in respect to the body 8 so that they extend obliquely thereacross and thereby position the sleeves 14 in pairs and with the sleeves of each pair spaced both longitudinally and transversely in respect to the body 8. The truss rod 12 extends below the tiey bars 10 and 11 and diagonally between the two outermost sleeves 14, and has in its ends bores through which the respective sleeves project. The tie bars 10 and 11 and truss rod 12 are supported from shoulders 15 on the sleeves 14, and which shoulders are in the form of nuts screwed onto said sleeves from the upper ends thereof and support the ends of the tie bars 10 and 11 and truss rod 12 at a point just slightly above the vertical center of the body 8.

The reinforcement 13 extends above the tie bars 10 and 11 and outward thereof, and parallel to the top and sides of the body 8 and is located substantially midway between said tie bars and the top and side faces of the body 8. This reinforcement 13 is supported on thiinbles 16 telescoped onto the sleeves 14 which rest on the end bars 11. Nuts 17 are screwed onto the upper end of the sleeves l14 land cla-mp the reinforcement 13 thereon and the sleeves onto the tie bars 11. On the lower ends of the sleeves 14 are heads 18 recessed to receive the heads of anchor bolts, as will presently appear.

The tie bars 10 and 11 are iiat, and the tie bars 10 aretwisted between thev sleeves 14 to increase their hold in the-cement and thereby more securely hold said sleeves against longitudinal movement in respect to the body 8. It will be noted that the ends of the sleeves 14 and thenbent laterally downward at 19 to further increase their 4holdin the body 8.` By reference to Fig. 2

it will be noted that the longitudinal center of the truss rod 12 is only slightly above the bottom face of the body 8 and from this point vthe end portions thereof diverge up- Vward tothe sleeves 14 to which they are at beveled to rest Adirectly thereof. .The metal reinforcement 13 eX- tends substantially the full length oli the body 8. It Will be noted that the improved railway tie has no projection whatsoeverv plates-may be easilyl replaced trom timerto time' or a number thereot1 used to levelup a rail. These plates 22 "have bores aligned with the bores inthe'sleeves 14- andthe anchor bolts 20 extend'upward throughisaid sleeves and bores 1in the pla-te 22 with? their heads seated in the'recessedfheads-l8 of said sleeves which hold `:said bolts `1from turning.
