RAILWAY-TIE AND RAIL-FASTENIN Specification of Letters Patent.
Patented Oct. 1, 1912.
' epplieation filed lune 22, 1912, Serial No. 705,287.
Be it known that we, Jnoon A. Hrnu and fi AL'l ER R. CARDIODY, citizens of the United States, residing at Chicago, in the county Illinois, have invented Railway-Ties and RaihFastenings, of which e following is a specification.
Our invention relates to a metallic railway tie and means for securely fastening the i to the track rails of a steam or electric vide an improved metallic railway tie transaction with simple, strong, economidurable and efficient means for firmly securing the track rails to the said improved metallic tie.
A further object of this invention is to provide novel fastening means for securing the track rail, to a metallic railway tie, and means for the insulation of the track rails from the said metallic tie.
Another tie as to prevent the track from getting out of its proper gage or alinement, and act as anti-creeping means to'prevent the track rails from creeping, thereby constituting improved means for insuring a maximum degree of safety for the roadbeds of railways.
' Another object of the invention is to vide means secured between the base of the track rails and the upper surface of the tie which serves as a waterproof insulating and resilient cushion, and to deaden the rumbling and rattling noise common on all railways.
The foregoing and such other objects as may occur from the ensuing description, are attained by the means hereinafter more fully described, and by the combination, arrange- -nentand location of the parts illustrated in the accompanying uiarly set. forth in hereto.
l tefere'nce now being had to the accompanying drawings which form a part of this specification and in which similar numerals of reference indicate like parts, it will be 1, is a cross-sectional view of the improved railway tie, showing in side elevation a portion of a track rail, and the means for securing said tie to the track rails embodying our invention. Fig,'2, is a side elevation of a portion ofour imdrawings and particthe claims appended V he prime object of our invention is to.
riveted to the object is to so secure the track pro-' plan view of a portion of a railway roadbed showing a portion of a track rail secured to a plurality of railway ties. Fig. is a perspective view of the insulating cushion plate removed from the tie.
6, is a plan view of the rail securing showing a portion bent upward and ward, and the forrail securing clip bolted and vertedplaln' view of the rail securing platshown in F 6, showing the fiat plate bet fore a portion is bent or curved \upward and forward. Fig. 8, is a side view of the insulating cushion plate and the rail securing plate, showing the fastening clip removed therefrom. Fig. 9,.is.in detail, a perspective view of the se uring clip and alinement plate bolted and riveted together, and Fig. 10, is a perspective view of the insulating fiber washer which surrounds the headed portion of the securing bolt.
In carrying out our invention, we provide an improved railway tie 1, which may be made from any suitable metal capable of attaining the objects sought to be obtained, hence it may be rolled, pressed, stamped up or formed by suitable dies. The metal shell constituting the railway tieproper is filled in any suitable or desirable manner With concrete material 2, thereby adding weight and strength as well as preventing corrosion on the interior of the tie and forming a solid and rigid interior for the said tie. The tie such as shown in Fig. 3, is made of the same shape and contour throughout its length, and is provided with a plurality of said plate. Fig. 7, is an in- Fig. plate transversely arranged securing bolts on rivets 3, which are passed through the tie from one side to the other, one of which bolts is preferably located at'a point beneath the base of each track rail, and serves to prevent the tie from breaking or springng away from the filling material, and thus upper portion of the pocket -forrning a flattened extension or shoulder 6, which serves as a seat for the headed porthem applicable or serviceable in connection with our improved rail securing means.
A cushion plate 8, formed as shown in Fig. 5, is placed on top of the tie, this plate being made from a number of thicknesses of waterproof paper to the desired degree of thickness constitutes an insulating and resilient cushion between the rail and tie thus serving to prevent the breaking of rails which is now common in the use of wooden ties, and said cushion plate also serves to deaden the rumbling and rattling noise which is common on all railways, and since it is firmly secured between the tie and the securing means hereinafter more fully described, it will not wear out by frictional contact, for the reason that the track rail securing means and tie are so rigidly secured together as to render them immovable.
A metallic securing plate 9, formed as shown in Fig. 6, is placed on top of the cushion plate 8, said plate 9 being provided on opposite sides and near eachend thereof ,with openings or perforations 10 and 11.
bent upward and over and ada To the upper surface of the plate 9 is rigidly secured near each end thereof a se curing clip 12, and an alinernent or gage plate 13, said clip and plate having perforations adapted to register with those in plate 9, and each plate 13 is rigidly riveted to the clip 12, the inner edge of each plate 13 resting against the side of the base portion of the rail 7 to insure its proper alinement and gage, and the inner end 14 of each clip plate 12 extending over and adapted to rest upon the upper surface of the base of the rail. One end of the metallic plate 9 is slit or cut a portion of its length at 15, and the cut portion 16 is then ted to rest in contact with the upper sur ace of the base of the rail. The securing plates 9 are arranged on the ties so that the upturned portion 16 on each tie alternately rests 011* the upper surface. of the base of the rail on the outside and inside of the rail, as clearly shown in Fig. 4 of the drawings, hence'the upturned portion 16-, being arranged on either side of the rail on eve "ot er tie, serves as an additional reserve i'listener and in the event cider-ailment will prevent the railfrom turning over or spreading.
An opening is" formed in the tie near as clearly shown in Figs. 1 and 2.-
either side and end thereof and in a vertical line with the opening 4-, through which is inserted upwardly at the side of the tie,
the main fastening bolt 17, screw-threaded at its upper end and provided with a securing nut 18, the latter resting in contact with the upper surface of the securing clip plate 1.2. Surrounding the fastening bolt 17 is an insulating fibrous sleeve 18, the upper portion of said sleeve terminating in contact wlth the insulating CUSlLIOD PlatB and thelower end of said sleeve restlng in contact with an insulating fibrous washer 19 the latter surrounding the head portion of the said fastening bolt to prevent contact by the head of the bolt with the metal por tion of the tie, thus bolt from the tie. The fastening bolt is passed upward through the hole in the'tie, the cushion plate, the metallic securing plate, the plate 13 and clip securing plate 12, and its screw-threaded end is secured by a fastening nut whereby the securing means is rigidly and firmly secured to the tie and track rails. It will be observed that the clip plate 12 is firmly riveted to plate 13, thus rigidly securing the two pieces together, the side of the rail base and being rigid with the clip prevents the turning aside or swerving of the .clip plate in the event that the latter should become loose. Itwill be perceived, that each metal securing plate is provided with two securing clip plates and an upturned portion, said clip plates and upturned portion adapted to clamp the upper surface of the base of the rail, and all of these members being bolted solid to the rail and tie prevent the .rails from creeping; since to permit creeping the ties and ballast must yield as a unit, and this will not occur since the weight of the ties and ballast will successfully resist the strain of the rolling stock.
It will be obvious that the shape of the tie, the material from which it is made and the secure fastening means prevents the upheaval of ties where frostand excessive moisture is located in the road-bed, such as will occur when wooden ties are used, and uigeven upheaval is thus rendered impossi la.
Having thus describedour invention, what we desire to claim and secure by Letters Patent is therein, said tie havin openings in its 11 per surface, pockets thereof in a vertical line with said openin and a recess or groove formed in either si e of the tie at the base portion thereof in vertical alinement with said pockets.
