' METALLIC RAILWAY-TIE.

Specification of Letters Patent. Patented lyl 4, 1920;

Application filed January 17, 1920. Serial No. 352,036.

To all whom itmag concern: I

Be it known that I, -OHARLES H. SWART- WOOD, a citizen ofthe United Statesv of America, residing at Boston, in the county of Suflolk and State. of Massachusetts, have invented certain new and .useful Improve.- ments in Metallic Railway-Ties, of which the following is a specification.

The primary object of the present invention is the provision of a metallic railway tie adapted for mounting the rails upon the ent seating for therails, permitting the re-.

moval of the railswithout displacing the tie whenever desired, the vertical .adjustment 6 of the rails being also'easily effectedupon the tie to compensate for expansion and contraction due to climatic conditions.

A still further object of the invention is the provision of a low-cost tie having railsupporting end portions provided with floating base members for. removably mounting the rails-thereon, whereby the rails and bases are readily removable from the tie or secured thereto for. elevating therewith as may be found desirable. 7

With these general objects in view and others that will appear as the natureiof the invention is better understood, the same consists in the novel construction, combination and arrangement'of parts hereinafter more fully described, illustrated in'the accompanying drawings,-and then claimed.

Inthe drawings forming a part of this application, and in which like designating characters refer to corresponding parts throughout the several views v Figure 1 is a side elevation of a railway tie formed afterthe inanner of my invention,

with rails transversely mounted thereon,

Fig. 2 is a top plan view thereof,

Fig. 3 is an enlarged vertical longitudi-' nal sectional view taken upon line III- 111 of Fig.2,

Fig. 4: is a horizontal sectional view taken upon line IVIV of Fig. 3,

Fig. 5 is a View similar to Fig. 3, with the rall-supporting base shown in elevation secured to the tie for moving therewith,

Flg. 6 is a side elevation of an end portion of the tie with parts broken away, and

Fig. 7 is an end view thereof.

Referring more in detail to the drawings, my lnvention comprises a tie proper'consist- 1ng of a body, preferably of cast metal, having end sections or housings 10 adapted for mounting upon the roadbed with an integral connecting web or bridge portion 11, the length of the body being the same length as a standard tie and the cross-sectional area of the housings 10 being susbtantially the same. 1

The housings 10 are of tubular form, each havlng'a chamber 12 with a cushioning block 13 of such material as wood, positioned upon the bottom 14 thereof, by spaced transverse ribs 15, the said block being adapted for the resllient seating of an adjustable base 16 thereon for operatively mounting the railway rails transversely upon the tie. Each base 16 is substantiallv cubical in form, centrally severed transverselv into separate halves 18 connected together by a bolt 19 for limiting the amount of separation between saidsections of the base. Frictional holding guides 20 upon the base sections 18 properly position the rails.

17 between said guides, and transversely of the top 21 of the tie housing 10, with the top plate 22 of the base 16 seated in a corresponding opening 23 in the top 21. A. joint 24; is formed between the ledges 25 at :the opposite edges of the opening 23, and the adjacent'edge portions of the plate 22, such connection being adapted to pre An adjusting screw 27 projects through the base 16, longitudinally of the chamber 12 being screw-threaded for a portion of its length having threaded engagement with an opening 28 through the outer section 18 of the base 16 while the inner end of the screw 27 is journaled through an opening 29 in the other section 18 of the base, with the head 30 at the inner end of the screw engaging the side thereof, as best illustrated in Figs. 3 and 4E of the drawings. The outer end of the screw 27 freely projects'through a vertical slot 31 in the end wall 32 of the housing 10, being furnished with a squared reduced end 33 for turning the screw 27 for drawing the sections 18 of the base 16 toward each other, or releasing them at will.

The said bolt 19 holds the lower portions of the base sections 18 against entire separation limiting relative movement thereof as heretofore noted and it will be evident that upon revolving the screw 27, in one direction, the sections 18 will be drawn together, frictionally engaging the guides 20 against the opposite edges of the base flanges 34 of the rail 17, seated upon the top plate 22, between the said guides. The rails 17 when positioned upon the bases 16, will be normally secured against creeping by the guides 20 as well as by clips 35 secured to the top plate 22, by bolts 36. Depending flanges 37 at the opposite sides of'the plate 22, overlie the sides of the housings 10, the bolts 36 preferably extending through said flanges 37. 7

Under normal conditions, the rails 17 being secured to the bases 16 in the manner described, with said bases positioned upon the blocks 13, provides astrong structure capable of long useand wear, and not likely to'get out of repair, it being seen that the base 16, may be readily elevated out of its opening 23, by lifting the rail 17 upwardly which is secured to said base 16 and carrying the same inwardlyof the track. WVhen it is desired to elevate the tie body, however, screws 38 are positioned through perfora tions 39 adjacent the edges of the plates 22 for engaging the threaded perforation 40 of the adjacent side portions 25 of thetop 21 of the tie as illustrated in Fig. 5 of the drawings, and at which time, the base Y16 and tie may be elevated together; 7

lVhen desiring to slightly raise the rails 17, the screws 27 may be turned in the proper direction for releasing the base sections 18 and disengaging the guides 20 from the rail base 34:, so that shims or spacing-blocks of theusual form and unnecessary to herein illustrate, may be forced beneath the rails upon the top plate 22 of its supporting base. The slot 31 also provides an outlet for moisture from the chamber 12 of the housing lO-and while the form of the invention herein set forth and described is be lieved to be the preferable "embodiment thereof, it will neverthelessbe understood that minor changes .may be made therein,

without departing from the spirit'and scope of my invention.

What I claim as new and desire to secure by Letters Patent, is V 1. A railway tie comprising spaced hollow housings'adapted for positioning'upon the roadbed, a connecting web between the tops of the housings, adjustable bases resiliflush with the top of the tie, upright guides upon the bases transversely of the tie adapted for frictional engagement with railway rails when operatively positioned upon said bases, adjusting means for the parts of the bases operable at the ends of the tie whereby said guides are adapted for movement toward and away from each other, the ends of the housings being provided with vertical outlets, retaining bolts positioned through the parts of each base-adjacent the bottom thereof, and positioning means for the bases upon the bottoms of .the housings.

3. A railway tie comprising end housings having openings through the top of the tie, two-part bases positioned within said housings with the tops of the bases substantially flush with the top of the tie,xupr-ight guides upon the bases transversely of the tie adapted for frictional engagement with railway rails when operatively positioned upon said bases, adjusting means for the parts of the bases operable at the ends of theitie whereby said guides are adapted. for "movement toward and away from each other, the ends of the housings being provided with vertical outlets,- retaining bolts positioned through the'parts of each baseadjacent the bottom thereof, positioning means for the bases upon the bottoms of the housings, whereby the bases are normally adapted for removal through said top openings and securingmeans between the bases and housings whereby the rail ,may be moved with said bases at will.

4. A. railway tie comprising spaced housings, each housing having an opening in the top thereof, and a vertical slot in its outer end wall, a connecting web between the tops of the housings, resilientrmembers within the housings upon the bottoms thereof beneath said-openings, a hollow base in two parts'mounted upon each resilient member with the tops ofthe bases substantially flush with the tops of the housings, operating screws swiveled through the inner part of each base and threaded throughthe outer part having projecting ends outwardly of said slots at the opposite ends of the tie, an upright guide upon each part of each base adapted for the seating reception of vrailway rails between the guides of each base whereby the guides are adapted for holding engagement with the base flanges of rails in their operative positions transversely of the tie.

5. A railway tie comprising spaced housings, each housing having an opening in the top thereof, and a'vertical slot in its outer end wall, a connecting Web between the tops of the housings, resilient members within the housings upon the bottoms thereof beneath said openings, a hollow base in two parts mounted upon each resilient member with the tops of the bases substantially flush with the tops of the housings, operating screws swiveled through the inner part of each base and threaded through the outer part having projecting ends outwardly of said slots at the opposite ends of the tie, an upright guide upon each part of each base adapted for the seating reception of railway rails between the guides of each base whereby the guides are adapted for holding engagement with the base flanges of rails in their operative positions transversely of the tie, positioning means for the resilient members and bases Within each housing upon the bottom thereof, complementally-formed adjacent edges between the base members and the adjacent edges of said openings, removable connections between the tops of the bases and housings and movement limiting means connected between the parts of each base beneath the operating screws.

In testimony whereof I afiix my signature.

CHARLES H. SWVARTWOOD.
