STEEL CROSS-TIE AND RAIL-CLAN?.

Specification of Letters Patent.

Patented Apr. l0, Mtl?.

Application led January 18, 1917. Serial No. 143,089.

To all whom t may concern:

Be it known that I, JosErr-r SHERMAN REED, residing at Vinnfleld, in the parish of Winn, and State of Louisiana, have invented a new and useful Steel Cross-Tie and Rail-Clamp, of which the following is a specification.

My invention, which has 'reference to improvements in railway ties and rail clamps, more particularly seeks to provide an improved, simple, inexpensive and stable con* struction of steel cross tie and rail clamp, in which cooperating portions of the tie and the rail clamping means are particularly designed for effectively retaining the rails in place and inrwhich the stress of the parts, under pressure of passing trains, is so distributed to the rail and the clamping portions that the rails are held from lateral hammering against the Aclamping elements and the latter so secured that the clamp securing members are relieved from shearing or torsional strain.

With other objects in view that will hereinafter appear, my invention is an improved metallic tie and rail clamp that embodies the peculiar features of construction and novel combination of the parts to be described,l

specifically pointed out in the claims and illustrated in the accompanying drawings, in which:

Figure l is a perspective view of a combined metallic rail tie and clamp embodying my invention.

Fig. 2 is a longitudinal section of one end of the tie, and illustratesthe rail clamp device as operatively applied to the rail.

Fig. 3 is a longitudinal section of one end of the tie and the rail clamp device that cooperates with the said tie end, the said device being shown in a position for being removed from the rail and the tie. i

Fig. 4 is a top plan view of one end of the tie, the clamp device being removed.

Fig. 5 is 'an inverted plan view of the same end of the tie.

Fig. 6 is an inverted plan view of the said end of the tie with the clamp device operatively applied thereto.

Fig. 7 is a perspective view of one of the rail clamp devices, and

Fig. 8 is a cross section of the rail clamp device and the tie taken on the line 8-8 on Fig. 3.

ln carrying out my invention, I provide a metallic tie, the or body portion Vof which is of the general inverted U-shape form in cross section having integral clamping members 2-2 for engaging the inner tread flanges 3-3 of the opposite rails 30-30, as shown.

At each end, the tie has a longitudinally elongated cavity or seat 4, the bottom 40 of which terminates with an inwardly and downwardly inclined aperture 5 that merges with a longitudinally extended undercut seat or cavity 6 on the under side of the tie and which extends inwardly from the aperture 5, the reason for which will presently appear.

rEhe lower side edges l0 of the tie l and the closure plate l?) have interlocking dowels and apertures, as shown.

The clamp members 7, the peculiar construction of which and their cooperative connection with the specially constructed seats and apertures formed in the tie,as before referred to, include a clamping head 70 having the usual clamping jaw 7l for fitting over the outside flange of the base of the rail.

Head 70 also includes a pendent body portion 72 that is adapted, when the parts are operatively assembled, for freely tting into the seat t in the upper face of the tie, as is best shown in Fig. 2, by reference to which it will be seen that the said body portion, formed with a transverse aperture 73, has suliicient longitudinal play in the seat l so that when the clamp is forced back to its limit or operative position, that is, when the rail 30 is placed in position, the rear edge 72d of the body portion 72, engages the end wall 4l() of the seat l and with the base portion 7 5 of the head' lapped over the sides and rear upper edges of the' said seat 4, thereby forming, as it were, together with the rail base a perfect top closure for the said seat Ll.

The body of the clamp 7 has a horizontal tread portion 76 which is flush with the top of the tie when the parts are assembled so as to be engaged by the rail and from the said tread portion, the body of the clamp merges into a vdownwardly inclined member 77 that passes through the inclined aperture in the tie and ends in a forwardly extended hori- Zontal member 78 which fits into the undercut seat on the under side of the tie, as shown.

Each end of the tie 1 is transversely apertured as at 15 to receivea locking bolt 9 that passes through the said aperture 15 and the aperture in the body portion of the clamp 72, when the parts are assembled as is best shown in Figs. 2 and 8, the usual clamp nut 90 being provided for engagement with the bolt 9.

From the foregoing taken in connection with the drawings, the complete construction, the manner in which the parts are operatively applied and the advantages thereof will be readily apparent to those skilled in the art to which my invention relates.

It will be noticed, by referring particularly to Fig. 2, that the reason of forming the two longitudinally alined seats in the upper and lower sides of the tie top, joining the sides by an inclined aperture, and providing a clamping member having the peculiar shape stated, that when applied, the clamp, while effectively serving to hold the respective base flanges of the rail down to the tie, the said clamp is so positioned upon the tie that the lateral stress from the rail is transmitted through the clamp directly against the tie, since the outer end of the clamp body engages the end wall of the seat l and thereby relieves the lock bolt from transverse stress.

Further, by forming the inner end of the clamp, as shown and described, the said end is caused to snugly fit the seat on the under side of the tie and form a bottom closure for the aperture through which the front end of the clamp is entered when adjusted for use. l

By reason of forming the clamp and the tie portion engaged thereby as stated, a rail fastener of a very simple construction is provided, that is highly eflicient in its operation and extremely strong and durable.

The rails may be quickly fastened upon the ties and, when necessary, the clamps can be almost instantly removed, since by removing .the connecting bolts 9 and tilting the clamp to the position indicated in Fig. 3, the same can be readily pulled up (see arrow) and out of engagement with the tie.

What I claim is:

1. In a combined rail tie and rail clamping means, the combination with a hollow metallic tie having a pair of opposing integral clamping members adapted for receiving the adjacent inner base flanges of a pair of rails, each 0f the ends of the tie having a longitudinally extended upper and a longitudinally extended lower seat portion, the upper and lower seat portions being in longitudinal alinement, and an aperture in the tie body connecting the said seat portions; of a clamp device including a head portion having a member for clamping over the outer base flange of the rail, a body portion for litting into the upperseat in the tie and in endwise abutment with the end wall of the said upper seat, said body including a tread portion adapted for being engaged by the rail base and an extension adapted for being slipped through the aperture in the tie that connects the upper and lower seats and with the outer end thereof adapted for resting up in the undercut seat when the parts are at their operative position.

2. In a combined rail tie and rail clamping means, the combination with a hollow metallic tie having a pair of opposing integral clamping members adapted for receiving the adjacent inner base flanges of a pair of rails, each of the ends of the tie having a longitudinally extended upper and a longitudinally extended lower seat portion, the upper and lower seat portions being in longitudinal alinement, and an aperture in the tie body connecting the said seat portions; of a clamp device including a head portion having a member for clamping over the outer base fiange of the rail, a body portion for fitting into the upper seat in the tie and in endwise abutment with the end wall of the said upper seat, said body including a tread portion adapted for being engaged by a rail base and an extension adapted for being slipped through the aperture inthe tie that connects the upper and lower seats and with the outer end thereof adapted for resting up in the undercut seat when the parts are at their operative position, the said body portion and the corresponding opposite walls of the sides-of the upper seat portion having alining cross apertures and a bolt and nut connection for coperating with the said apertured portions of the seat and the body of the tie as set forth.

8. A combined metallic railway tie and rail clamp comprising a hollow body having a pair of oppositely disposed integral rail clamps for engaging the inner adjacent fianges of the opposite rails, the outer ends of the tie each having an `elongated seat in the top and a similar seat in the bottom, the two seats being in longitudinal alinement and a diagonally projected aperture that connects the top and bottom seats, a clamp having a jaw for fitting over the outer base flange of the rail, and a body portion adapted for sea ting in the top seat of the rail, said clamp also including an inclined member adapted for projecting through the inclined aperture in the tie and a forwardly extend'- ed end for litting into the seat in. the under side of the tie and means for holding the clamp positioned in the said upper and lower seats and in the inclined aperture.
