RAILWAY-TIE.

Specification of Letters Patent.

Patented Mar. 19, 1918.

Application filed November 15, 1917. Serial No. 202,197.

To all whom it may concern:

Be it known that I, WILLIAM A. LOCKARD, a citizen of the United States, residing at West Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvei and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

. My invention relates to improvements in metallic railway ties.

The object of the invention is to improve and simplify the construction of metallic cross ties and more particularly those in which the track rails that are supported upon them are to be electricallyinsulated from each other.

With the above and other ob ects in view,

the invention conslsts of-certar'n novel features of construction, combination and arof parts as will be hereinafter more fully described and claimed.

In the accompanying drawings Figure 1 is aplan view of a metallic rail tie constructed in accordance with my invention and showing the track rails secured thereto; 1

- Fig. 2 is a vertical longitudinal section on the line 22 of Fig. 1; 1

Figs. 3 anda are transverse sectional views on lines 3-3 and 4.& respectively of Fig. 1, and, Fig. 5 is a detail perspective view of portions of the tie separated.

Referring moreparticulafly to the drawings the numerals 1 denote the two track rails secured to the improved cross tie which is composed of two box-like sections2 and 3, secured together at their inner ends. Each of these half sections of the cross tie are of U-shape in cross section having a bot tom wall and upright side walls between which latter at the extreme ends of the tie are riveted or otherwise secured 'flanged end plates 4 as clearly shown in Fig, 1.

Formed in the upper edges of the vertical walls of the tie sections notches in which the bases of the track rails are received, such railbases resting upon supporting plates 5 arranged in saidnotches. If desired the plates 5 may have their ends downturned to prevent them from shiftinglongitudinally under the track .ralls. At

held together on the tie the construction .-locked by locking wedges 10*,

right bottom flange 14, such flanges formed with openings as clearly shown in 100 22 are undercutsulating 1 and 2 the rail is shown engaged with a shoulder 6 formed by the undercut wall of one of said notches and it is held against said shoulder by a horizontal wedge plate 7 other undercut wall of said notch and has formed upon it an upright bracing flange 8 which engages the web and under side of the head of the track rail l to brace the latter. The wedge 7 is secured in position by a vertical wedge 9 which passes through slots in. it and the plate 5 and has one of 'its edges bearingagamst the inner side of one of the vertical walls of the tie section 2. Owing to this construction when the wedge 9 is forced downwardly it will tighten the wedge 7f The'tightening wedge 9 is retained in position by a. locking wedge 10 preferably formed from a strip of metal bentupon itself into the shape of a cotter pin and after it has been driven into locking position itsends are turned outwardly to retain it in such position. Where the meeting ends of two track rails are to be shown at the right hand side of Figs. 1 and '2 is employed. This construction is similar to the one just described with the exception that two wedge plates 7 areused, one being on each side of the track rail and they are'eachprOVided with an upright flange 8 which serve the purpose of fish platesand which have on their inner faces i I grooves 11 to receive the usual rail bonds for electrically connecting the abutting rails. The wedges 7 are forced into position by tightening wedges 9 which are. in turn as will be understood on reference to Figs. 2 and 3.

The two tie sections 2-8 have their abut- 95 ting ends secured together by bolts 12 and said ends are formed with inwardly extending upright flanges 13 and a connectin fieing Fig. 5 for the reception of the bolts 12. To

electrically insulate .the two lines of track rails, I provide between the abutting flanges 13-14 of the two tie sections a U-shapcd inholes to register with those in said flanges, see Fig. ,5. I also provide around each bolt 12 a sleeve or tube 16 of suitable insulating material and underneath the heads and nuts of the bolts insulating washers 17 as clearly 110 It will be noted that when shown in Fig. 2. the tie sections 2-3 are assembled with the which is engaged with the member or plate 15 which has bolt U-shaped insulating member between them and the bolts are arranged in position with their insulating sleeves 16 andwashers 17 upon them, the two sections of the cross tie will be securely held together and at the same time'each section will be insulated from the other.

The bottom walls of the tie sections 23 have their outer portions flat while their inner ends are inclined upwardly as shown at 18 in Fig. 2 whereby when the tie sections are assembled the bottomof the tie will have at its center a recess or cavity which will tendto anchor thetie in the blast or roadbed in 'which it is mounted. This construction reduces the area of the inner ends of the tie-sections and hence reduces the amount of stood and it will likewise be understood that slight changes in the form, proportion and arrangement of parts may be resorted to Within the spirit and scope of the invention as claimed.

I claim:

A metallic cross tie composed of two half sections having rail clamping means thereon, said sections being of U-shape in cross section and having the inner portions of their bottom walls inclined upwardly and inwardly and their inner'ends formed with inwardly projecting flanges upon the bot tom and upright walls, a U-shaped plate of insulating material arranged between said flanges of the two sections, bolts passed through said insulating plate and the flanges to unite the tie sections, and insulating sleeves and washers arranged on said bolts.

In testimony whereof I have hereunto set my hand in the presence of two subscribing" Witnesses.

WILLIAM ALONZA LOCKARD. Witnesses:

CHARLES A. OBRIEN, ARTHUR E. STANGE.
