BAIL-FASTENING DEVICE.

Specification of Letters Patent.

Patented June 8, 1915.

Application filed. November 9, 191%. Serial No. 871,159

vide extremely simple yet highly efficient means for clamping the rails of a track upon the ties thereof.

In carrying out the above object, I employ certain novel features of construction and combination herein described and claimed and shown in the drawings wherein:

Figure 1 is a side elevation of a tie constructed in accordance with my invention, showing a pair of rails resting thereon, in section; Fig. 2 is an end view of one of the ties, and illustrating a side view of a portion of one rail; Fig. 3 is a top plan view of one of the ties and portions of a pair of rails thereon; Fig. 4 is a vertical transverse section as seen on the line 44 of Fig. 3; Fig. 5 is a detail transverse .section'as seen on the line 55 of Fig. 3; Fig. 6 is an inner end view of one of the clamping blocks; Fig. 7 is a bottom plan view thereof, Fig. 8 is a top plan view of one of the-clamping blocks showing a slightly different form of construction, and Fig. 9 is an end view, similar to Fig 2, but showing the formation of the upper portion of the tie, when a set screw to be described, is forcibly tightened.

In the accompanying drawings, forming a part of this application, the numeral 1 designates a transverse I beam which constitutes a railway tie, '2 indicates a pair of longitudinal rails whose base flanges 3 rest upon the upper flanges 4: of the I beam, and the numerals 5 and 6 designate respectively inner and outer rail clamping blocks.

"The blocks5 and 6 are each of rectangular formation, as seen in the various figures of the drawings, and are provided with T slots 7 in their lower portions, the shanks of said slots opening through the bottoms of the blocks and extending transversely across the same, as shown. These slots receive the upper portion or, inother words, the flanges 4 of the tie 1. In addition to the slots 7,

each of the clamping blocks is provided with a longitudinal groove 8 in its inner end, these grooves receiving the base flanges 3 of the rails. With the parts in this position, a set screw 9 is passed through the outer end portion of each of the clamping blocks and threaded into contact with the I beam or tie, the lower or inner ends of these set screws being pointed as seen at 10. These points are projected into recesses in the tie, thereby preventing the clamping blocks from slipping thereon.

In Fig. 9, I have shown the manner in which the upper flanges 4 of the I beam 1, may be dished or grooved, by excessive tightening of the set screw 9, this operation being possible since the tightening of said screw draws the entire clamping block upwardly, thereby bending the flanges 4: upwardly beneath the rail 2. This becomes extremely advantageous, since the I beams 1 may be made of hardened steel, the upper corners of said beams then constituting biting edges for preventing creeping of the rails 2, when the parts stand as seen in Fig. 9. When the ties and rails are new and unworn, it is not necessary to ti hten the screws 9 to the extent shown in Fig. 9, but when continual vibration has worn the rails and clamps. it is highly expedient to so tighten said screws, for the purpose set forth.

Although in most cases. but one screw 9 is sufficient for each clamping block, three or more set screws may be employed as seen in Fig. 8. These screws may be positioned as seen in this figure or in any other appropriate manner.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that an extremely simple device has been provided for carrying out the object of the invention, yet that the efiiciency of the device will not be impaired by such simplicity. 1

It will be readily understood that the clamps 5 and 6 may be adjusted inwardly and outwardly upon the beams 1 to provide tracks of either narrow or wide gage, these adjustments being also made when the upper portions of the beams 1 become worn after long use.

I claim:

The combination with an I beam whose upper corners are sharpened, a rail resting on said beam, and fastening means abutting one side of the rail, of a rectangular clamping block resting on the beam and having a transverse slot in one end receiving the base-flange on the other side of the rail, a pair of L-shaped flanges depending from the two sides of the block and having their horizontal portions contacting with the under sides of the horizontal flanges at the top of the I beam, and an upright set screw threaded downwardly through said block and bearing against the top of said I beam directly above its upright web, whereby tightening of said screw may deflect said horizontal flanges upwardly to present their sharpened upper corners for contact with the rail.

In testimony whereof I-have hereunto set my hand in presence of two subscribing witnesses.
