CROSS-TIE FoK ILwAYsf Specification of Letters Patent. Pat t d May 12, 1914,

Application filed March 13, 1913, Serial No. 754,118. Renewed Q c'tober 11, 1913i Serial No. 794,718.

To all whom it mayconcern Be it. known thatI, LAWRENCE C. Moon-Ev, a citizen of theUnited States." residing at l\lontgomery, in the county of Montgomery and State of Alabannnhave invented new and useful Improvements in Cross-Ties for Railways, of which the following ista speei; tication. e I r r V Y This invention relates -to an improved road which shall 'be-Ystronger, relatively cheaper and'more durable than cross-ties ll()\\' ll]. ('Ollllnoll $0. i I. The object of this invention is the production of a novel cross-tie,'made of concrete or other suitable plastic material, containing wooden blocks or sections near each end to serve as resilient rail jse: ts, and reinforced by longitlnlinal bars or r0 tending to each end of tlie tit a-ongnfna wooden sections orpillow blocks. As a further reinforce for the tie a" cradle of interlaced rods or reticulated metal is en'ihedded inthe concrete bencath'em-l iilow block the ends of min'"e'raalefinetmempx I trill into'the body oftheiie and there terminate in the form of loops or hooks. .aid cradles serving to strengthen that portionof the cross-tie below the blocks. and which is thinner than in any otherportitm. fromthe hammer-like blows of thewheels of passing trains,

The improved tie is of rectangular crosssection with parallel vertical sides and parallel top and bottom the latter having a shallow central recess for about one-third its length extending across the tie from side to side.

The wooden sections or pillow blocks extend entirely across the tie and are retained in place by the longitudinal reinforcing members, projections on the sides of the blocks embedded in the concrete, and concrete ribs covering a portion of thelo'wer ends of the blocks which are chamfered at their corners for this purpose. Resting on each pillow block is a seatplate. for the ail. the ends of which are turned down over the ends of said blocks and covering the upper part thereof, which-in connection with the concrete extending over the chamfered lower portion of said block ends. leave very little of said block exposed to the elements.

To more fully disclose the novel features of the invention, attention is directed to .the.accompanying drawings forming a part:-

of this specification and 1nwlnch tie with aportion of two rails spiked thereto. -;I 1g.- 21s a. perspective view of two red. Fig. 3 is a side elevation of the crosst c; 'Fi 'i' 4fis a vertical longitndinaljsecommt .vie} larged "cross-sectional" 'view" on the line 5-7 of Fig. 4." Fig. (3 is an enlarged end view of one of the pillow blocks. Fig. 7 is a horinontal sectional view of the cross-tie. Fig. 8 1s a perspective view of the reinforcing cradle.. Fig. 9 is a view similar to Fig. 1, showing a modified form of the cradle. Fig. 10 is .a perspective view of the modified -radle. I j

In "the*fd' i'ngs? in which likenet'erenee .cliaraetersareused for the same parts in all the figures A indicates the cross-tie as a "whole made: :of plastio material such as cement concrete strengthened by metal rods ovi pillow-blocks; to support the. rails and re ceirethefast'eniiig spikes. I The improved cross-tie of the usual length. height. and width but preferably formedwithashallow recess. or depression 10, in itsu'nderside forabont one-third its length to given firm seat tothc cross-tie beneath the rails and permit the material forming the road bed to collect between the rails which, owing to the hammering of the wheels of passing trains, it has a natural tendenq' to do, without interference from or binding the cross-ties. This recess or depression by permitting the material to collect or .be filled in between the rails tends to prevent longitudinal creeping of the ties.

Embedded in the cross-tie near each end is a wooden section-or pillow block 11 of less height than the cross-tie but extending entirely across the same, the ends and the upper surfaces of the pillow blocks being tlush respectively with the vertical sides and top of the cross-tie. Similar frusto pyramidal projections 12 extend from opposite sides of the pillow blocks in the longitudinal center of the cross-tie and are embedded in the concrete formingthe same. A PGlfOltllitlll extends through each block and said projections to receive a longitudinal tie bar 11 threaded at its ends for nuts 14 which when Figure 1'.is atop plan view of a crosspillow blocksconneeted together by a tie l-Ofi-thersante.

Thesejcra'dles"arepreferably made of bars or rods. interlaced or crossed, as clearly shown'in Fig. 8. but if desired such cradles a may be. madeflot". platQSfifl reticulated metal as shown in Fig, '10." [The lower corners of the pillow blocks] 1 above the thin portion l-t of the cross-tie are cut away or chamfered. 5 "as at 255 and such cut awn portions filled with concrete thus forming upstanding ribs or braces 26 which tend to strengthen the thin portion Qland also serve to cover the lower parts of the'ends of the pillow blocks.

leave but little of saidthe life of said blocks, which may beturther protected by treating them With creost'ite or other suitable wood perservatire.

It is to be noted that the pillow blocks 11 are svnnnetrical in their formation. At each end of the bottom of said block is a chainfered corner and on each; side is a frustopyramidal projection 1:2 similarly disposed with relation to the axis of the opening therein tlnongh which the tie-rod 1 passes. From this it will be evident that in assembling the parts to form the tie either side of the block with a plt'ljtttlttll may be placed outermost or toward the end of the tie. or a block may be placed at either the right or the left thereof, the blocks being rnnnctrical itis immaterial at which end of the tic they are placed; 'or' which s'ide't'zn-es'the tie end; a

In the manufacture of this improved cross-tie the tie rod 13 is run through the central opening in the pillow blot-ks. the

bearing'plates 17 placed over the ends of said tic-rod in position on the projections 12. and the nuts 14 screwed firmly against the platcs holding said pillow blocks the proper The rcint'orcc rcds or bars 16 are then threaded through suitable penings in the pillow blocks and their ends =cnt upon thcmselres'as shown. This skeleton structure is now placed in a mold of suitable shnptnjvitliill)Yhich have been positioned and suitably secured cradlcs l.' and concrete poured into said mold in the ll llill manner. Alter hardening. the cross-tie is removed from the mold and finished in well known manner.
