INSULATING RAIL CONNECTION' FOR METAL TIES.

Application filed May 26,

This invention relates to improvement in metal tie and rail connections and part-icularly to connections of such character as will insulate and cushion the rail from the tie.

The object of this invention is to produce a simple, strong and durable insulating railconnection for metal ties constructed with particular reference to silence under traffic and to immunity to excessive strains and damage from the effects of temperature changes, etc.

`Wit-h this object in view my invention consists in an insulating rail-connection for metal ties having certainv details of construction and combina-tions of parts as will be here-` inafter described and particularly recited in the claims.

In the accompanying drawings:

Fig. 1 is a broken top or plan view of one end of a metal tie and a section of rail, showing my improved insulating rail-connection;

Fig. 2 is a side view thereof;

Fig. 3 is a longitudinal sectional view on the line 3-3 of Fig. 1;

Figure 4 is a corresponding view on the line 4-4 of Fig. l; y

Fig. 5 is a transverse sectional View on the line 5--5 of Fig. 2;

Fig. 6 is a detached perspective view of the rail-supporting pla-te;

ig. is a corresponding view of the insulating cushion-block; and

Fig. 8 is a top or plan view of one of the rail-clips det-ached. Y

In carrying out my invention as herein shown, I employ a trough-shaped sheetanetal tie 10 having the upper edges of its side walls' 11 turned outward to form stiffening flanges 12 upon the upper face of which near the end ofthe tie I position a rail-supporting plate 13 which spans the gap between the respective side walls 11 and is secured at its corners to the said flanges 12 bymeans of rivets 14.

The central portion of the rail-plate 13 is struck downward to form a shallow pocket 15 depending between and extendingy lengthwise with respect to the side walls 11 of the tie and designed for the lreception of a Correspondingly-shaped blockl of wood or other suitable insulating and cushioning material. The respective ropposite ends of the rail-supporting plate 13 are turned downward between the side walls 11 of the tie to form complementary legs 17 which snugly engage theV said side walls 11 and the bottom 18 oblong 1928. Serial No. 280,705.

of the tie so as to assist in bearing the load andin stiifening the tie-structure- Extending' transversely across and resting upon the upper face of the block v16 about midway the length thereof I position the rail 19 which is anchored in place by means of four corresponding rail-clips 20 substantially U-shaped in cross-section and having their side flanges 21 formed with aV plurality of notches 22 into which the lateral edges lof the base 23 of the rail 19 extend, as clearly shown in Figs. 2 and 3.

rlhe outer end of each of the four railclips 2O above mentioned is struck upward to form a shallow downwardly-facing pocket 24.to receive a domical boss 25 offsetting from the upper face ofa small rectangular fulcrum block 26 of insulating material. Midway the length of eachof the said rail-clips between the side flanges 2l thereof I strike the metal downward to form a spherically-contoured socket 27 provided with` an'axial clearancepassage 28 and adapted to receive a ballended sheet-metal cup 29 which in turn receives a bushing 30 of insulating material, the upper end of whichis formed with an annular Harige 3l extending over the outwardly-turned annular flange 32 .of they cup 29, which latter is also formed with an axial clearance-passage 33. Y

Extending axially through the insulating bushing 30 of each rail-clip and through the clearance- passages 28 and 33 aforesaid, YVas well as through y clearance- slots 34 and 35 formed respectively in the side edges of the rail-supporting plate 13 and the flanges 12 ofthe tie 10, is the bodyfportion `of`an L'- shaped tiebolt 36, the lower laterally offset end 37 of which'. is adapted to extend inward into the interior of the tie through either one of a pair of perforations 33 and 39 formed in the side walls 11 of the tie about midway the height thereof and to one side of the vertical center of the `rail 19. It'will be noted that a pair of perforations 38 and 39 is providedfer each tie-bolt.

'Ihe upper end of each of the four tie-bolts -36 is threaded for the reception of a nut 40 which bears against the outer faceof a washer 41, the inner face of which in turn bears against the insulating bushing 30 aforesaid. By screwing down upon the respective nuts 40 of the four obliquely disposedtie-rods 36, the same will in turn pull downward upon the rail-clips 20 and thereby hold the rail firmly against both vertical and lateral displacement upon the upper face of the insulating cushion-block 16. 1

It will be understood by reference to the drawings that four rail-clips 2O are employed, two of which are positioned over each of the outwardly-turned flanges 12 of the tie 10, and

Y that of each pair of rail-clips one is disposed upon one side of the rail and the other` upon the opposite side thereof. Beneath each railclip the flanges 12 and the opposite sides of the rail-supporting plate 13 are provided respectively with the clearance- slots 35 and 34 aforesaid, through which the respective tiebolts 36 pass.

In the event that it is desired for any reason to change the angle of inclination of the tie-bolts 36, this may be effected by shifting the inwardly-offsetting ends 37 thereof from one to the other of the perforations 38 and 39 already described and by engaging various ones of the notches 22 in the rail-clips with the edge of the base 23 of the rail. The domicalv boss 25 of the insulating fulcrum-blocks 26 which fit vwithin the upwardly-struck sockets 24 ofthe said clips will under all ordinary conditions prevent the displacement of the said blocks with respect to their complementary rail-clips.

I wish to call attention to the fact that by means of the construction above described, in which the tie-bolts 36 engage the side walls of the trou gli-shaped sheet-metal tie, not only is the rail firmly held in place but the railsupporting plate is very largely relieved of the strains which would tend to displace it lengthwise of the tie. Furthermore, by eX- tending the legs 17 of the supporting-plate downward into the tie, the transverse rigidity of the latter is so much enhancedv as to practically preclude the possibility of its'collapse.
