RAIL-FASTENING.

Specification of Letters Patent.

' Patented June 11, 1907.

Application filed September 26. 1906. Serial 1:... 36,273,

fastenings, and consists in certain novel constructions and combinations of parts as will be hereinafter described and claimed.

In the drawing Figure 1 is a top plan view of the invention. Fig. 2 is a cross-section on about line 22 of Fig. 1. Fi 3 is a detail top plan view of aporti'on of t 1e tie. I Fig. 4 is a detail vertical section -illustratin gthe ap plication of one of the bolts to its slot in the tie, and Fig. 5 is a detail view illustrating the application of the other bolt to its tie slot.

The tie A is. adapted to receive the rail 13 and may be provided at its side edges with the depending flanges'A, as will be understood from Fig. 2 of the drawing. The rail B rests flat upon the tie between theopposite slots C and/D, the slots D being preferably arranged in pairs, as will be understood from Figs. 1 and 3 of the drawing. These slots C and D'receive the bolts E and F for holding the clamp plates G and H, as shown in Figs. 1, 2 and 3. Ordinarily the clamp plate H is arranged at the outer side of the rail and the clamp plate G at the inner side of the rail so for convenience of reference I will refer to the plates H and G, respectively, as the outer and inner clamp plates. These clamp plates are recessed in their inner sidesat h and g to receivethe base of the rail B and are extended at their ends at h" and g to bear against the web of the rail and thus insure the holding of the rail by the clamp plates even should the.

bolts become so loosened as to permit the shoulders at h and g to ride above the outer edges of the rail base so that the clamp plates will operate to-secure the rails as long as said plates are held by their bolts whether the nuts be tight or loose. I f

The 'bolts E are secured in the slots G and the bolts F in the slots D and these slots are provided at one end with enlarged portions C and D to receive the heads of the bolts and said slots are elongated in a direction at a right-angle to the rail and the enlarged portions C andD of the slots are at the cor-. responding ends of their respective slots, so thatwhen the bolts are inserted the reduced or smaller ends of the slots are at the outer ends thereof with respect to the outer side of the track so that the bolts will be held as against any tendency by the spreading of the rail againstadjustment to the enlar ed ends of their respective slots. The bolthas its head E adapted to be inserted through the enlarged portion C of the slot C and the shank of the bolt adjacent to the headE is squared at E with its square of such size as to permit it to be moved along the slot C and its diagonals of such length as to permit the bolt to fit at its corners in notches C in the opposite sidestof the slotCwhen the bolt is so turned as will be understood from Fig. 3 of the drawin so that when in this adjustment the bolt will be locked from movement within the slotas will be unders ood from Fig. 3 of the drawing. Ordinarily I provide several notches C so the bolt may be secured at difi'erent points within the slot C as desired. This'bolt E extends up through the clamp plate G and thence through awvasher G upon said clamp plate and receives the nut e as shown in Figs. 1 and 2 of the drawing. In Fig. 5, I show the bolt in dotted lines as inserted through the enlarged portion C of the slot C- and in fulllines as held within the slot C by the fitting of its corners in the notches in the said slot, as will be understood from Figs. 3 and 5.

The slot D has its enlarged portion D in the form of asemici'rcle, this semicircular end D permitting the insertion of the head F of the bolt F when the latter is turned to inclined position, as shown in Fig. 4, after which the bolt may be adjusted along the slot I) to the position indicated in dotted lines in Fig. 4, and then passed u through the opening H in the clam plate I, thence rounded side sloped at d to facilitate the introduc'tion of the bolt head. as'best shown in Figs. 2 and 4.

What I claim is 1...Tl1e combination with the rail and the clamp plate G, of a bolt E and a tie having a slot notched in its opposite walls to receive the corners of the boltshank whereby to lock of the bolt head, the rounded side of'said enthe bolt when applied to secure the clamp larged portion being sloped to facilitate the 10 plate, substantially as set forth. mtroduction of the head,substantially as set 2. The combination with the rail, the forth. clamp plate and the bolt for securing the AUGUSTUS W. AVERY. same, of a tie plate having 'a slot receiving Witnesses:

said bolt and provided with an enlarged J. W. LANE,
