WILLIAM GALT CHIPLEY, OF ATLANTA, GEORGIA.
REINFORCED TIE.
To all whom t may concern Be it known that I, VILLIAM G. CHIPLEY,
citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful improvements in Reinforced Ties;
and I do hereby declare the following to be j a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make y and use the same.
This invention relates to reinforced coni crete ties.
One of the chief objects of the invention the said body port-ion having no recesses or i the like therein for the reception of the rail, such recesses being provided however in an upwardly projecting member formed upon and integral with the tie proper.
.i further object is to provide a particular and improved type of reinforcement which involves the use of a channel incinlier preferably formed of expanded metal and having its central iiat portion located adjacent the upper surface of the tie, the open portion of the channel and the free edges thereof being adjacent the lower side of the tie.
furthe;l object is to provide in connection with a reinforcement such as that menlioned7 which is of uniform size throughout the length of the tie` an additional reinforcement which in the preferred form of my device uiay consist of a plurality of heavy longitudinal wires or rods, and in another form of a wire mesh, the additional reinforcement in either case being located between the channel member and upper surt'ace of the tie and being detlected adjacent the walls of the recesses for receiving the rails in order to reinforce the said walls,` and to reinforce the lower wall of the recess and the body portion of the tie proper below the recess, the metallic structure extending to the base of the tie.
Particular emphasis is laid upon a stirrup like member formed as shown in Fig. 7, which reinforces the edge portions of the walls of the recess and extends to the base of the tie, and further ties the body portionby means of that portion which lies adjacent to the edge of the walls, extending Specification of Letters Patent.
Application filed May 24, 1913.

l from one side of the body portion to the other side.
In the accompanying drawings: Figure l is a view of the tie partly in side elevation and partly in vertical longitudinal section, i the central portion of the tie being broken away. Fig. 2 is a fragmentary View partly t in top plan and partly in horizontal section j showing' the arrangement of the longitudinal 1 wire reinforcement. Fig. 3 isavertical transl verse section through one of the recesses for j receiving the rails. Fig. 4 is a View in ver- I end of a tie showing a i slightly modified form of reinforcement. y li ig. 5 is a top plan view of certain of the l tical section of one structure shown in Fig. 4. Fig. 6 is a ver` tical transverse section of the modification taken through one of the recesses. Fig. 7 is a perspective 'View partly in section of a portion of a tie showing a recess and a particular type of reinfo 1cement therefor also incorporated in the structure shown Ain Figs. 4 and 5. Fig. S is a` detail showing the wire iuesli illustrated in top plan in Fig. 5, before being folded as in Fig. (i.
ln the several viewsv the tie is indicated by l0 and the recesses for the reception of the rails by 15 and 16. The tie is substantially rectangular in cross section throughout its body portion and is reinforced by a channel like device '1T which may be formed of expanded metal which is also of uniform size throughout its length. The open side of the channel is on the lower side of the tie so that the upper portion thereof and the sides of the tie aie fully reinforced by a member of arch like construction, the crown of the arch being at the top. Additional reinforcement provided by employing heavy wires or rods 1S which extend from the lower side of the tie at each end upwardly next to the surface of the end portion, and then extend lengthwise of the tie to the edge of the adjacent recess for the rail. The wires 1S and 182l adjacent to the sides of the tiev extend outwardly in the direction of the inner tapered walls 1.9 of the recesses and further extend to a point near the base of the tie on the outer side of the channel reinforcement.
The formation of the outer wires is shown in Fig. l and it will be seen that a stirrup like member is provided which extends for a short distance along the base portion of the tie below the recess of the rail and reinforces the walls of the recess as well as the sides of the tie and a portion of the base. The outer wires further reinforce that portion of the body of concrete which is disposed above additional ri-inforcement and additional thickness of the body portion at the point stated is to provide additional strength where the rails have their bearing. To state the matter ditferently, a reinforced tie constructed towithstand the maximum strain if provided with recesses directly in the body portion thereof l as, or will have, under the present construction an additional margin of safety of a very material extent. The thickened portions 2t) and Q1 are further reinforced, as is also the tie throughout its length and within its upper surface by eral intermediate wires or rods designated 18. These wires have a stirrup lilie formation of less extent than that of wires lo and 18a, the lower portion cf the stirrup being embedded in the lower wall oil the recess. In the drawings l have shown a metallic chair or rail suj'ij'iorting device 2 which has its bearing on a wooden block 2o mounted directly above the lower vall of the recess. The block is provided in order that the rail may be suitably cushioned and the chair member is ordinarily tapered from end to end for the reception of wedge blocks correspondingly tapered as shown in my 1I. Patent No. 1,030.230, issued June 1S. Y191;).
In the modification shown in Fig. t and the following views of the dra wing. the body portion and the channel reiniirceiuent are of similar construction. Instead of employing longitudinal tie rods separated from one another as in Figs. 1 and 2, I employ in the modification a wire mesh which may coinprise a central portion 3() constituting one layer of the mesh when embedded in the tie and portions 31 and 3Q which are folded beneath portion ffl() in the manner shown in Fig. G, in order to form a double thickness` of the mesh when considered as a reinforcement in itself. This wire mesh structure is deflected as shown in Fig. 4, around the recesses of the tie, and reinforces the side and lower walls thereof, as described in connection with the preferred form. I do not carry any portion of this wire mesh to the base of the tie, but provide an additional reinforcement for the portion supporting the rails by employing a device which may be termed a double stirrup member 35 having lower portions 36 located near the base of the tie below the recess, upwardly extending and inwardly inclined portions 3T which project along side of the walls of the recesses, and the transverse members 3S which are located within the walls adjacent the extreme edges thereof and extend from one side of the tie to the other for the purpose of reinforcine i t l i i i i l l l l l i and tying together this portion of the concrete body. It will be observed that a reinforced pedestal is provided below the rail which in a measure cmistitutes a separate the tie proper at points 2O and 2l adjacent the recesses. The object ot this reinforced rail supporting' device, and is largely independent of the reinforcement extending` the full length of the tie.
l`ransvcrse strips 8 are perforated and arranged across the longitudinal wires, as in Figs. 1 and 2, for holding the wires apart until the concrete is poured and has properly set. As many of these transverse strips may be. employed as desired.
