COMBINATION RAIL AND TIE FASTENER- Specification of Letters Patent.

Patented Jan. 2, 1906.

Application filed $eptember 21, 1905. Serial No. 279,393.

To alZ'whom it may concern! Be it known that I, FRANoIs M. CRossLEY, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Combination Rail and Tie Fasteners; 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, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which forma part of this specification.

This invention relates to new and useful improvements in fastening devices for metallic cross-ties and by means of which the steel rails are rigidly connected tosaid ties without employing screw-openings or bolt-openings or any kind of openings in the ties or rails.

The invention is not only suitable owing to its simplicity and convenience as a permanent means for connecting rails with metallic ties within a bed of concrete, but it is highly practicable and available in temporary construction-work where it is desired to quickly lay a temporary track. The fastening means is further highly serviceable as a single device may be utilized in connection with any of the forms of metallic ties employed in railway construction.

Preceding a detail description of the invention, reference is made to the accompanying drawings, of WhiChf Figure 1 is a cross-sectional View illustrating my improved rail-fastener in position within a bed of concrete. Fig. 2 is a detail view of the fastener, looking to'the right in Fig. 1; Fig. 3, detail views showing the crosssectional forms of a variety of metallic ties any one of which is available for the uses and purposes of my improved fastener.

In adetail description of the invention similar reference characters indicate corresponding parts.

The structural features of my improved railfastener are embodied in the form of a clamp 1, which has an angular opening consisting of

parts

2 and 3, which communicate in the form of a T. From the upper portion of the clamp there extends laterally a lip or projection 4, which clamps the edge of the rail-flange 5 and clamps said rail firmly against the top of the cross-ties6. Through the top of the clamp there is a screw-threaded opening 7 which is substantially in alinement with the body of tie in the middle thereof and rigidly unitesthe cross-tie and the rail. This screw has a suitable Wrench-head, by means of which a proper leverage may be applied to the screw. The opening in the clamp at the bottom is of a tapering form to provide a bearing-surface on one side of the clamp, which, in effect, forms a fulcrum for the points of contact 10 and 11, which, it will be observed, are the engaging points between the screw and the cross-tie and between the clamp and the rail-flange. Owing to the formation of the opening in the clamp, it is adapted for use in connection with any of the forms of cross-ties as shown in Fig. 3. In the use of either of these forms of cross-ties the binding-screw 8 is the same in its operation and the points of contact between the clamp and the rail, and between the binding-screw and the tie, and the clamp and the tie are, the same.

The simplicity and utility of this fastener can but be readily appreciated. In its operations it is simply slipped over the ends of the ties and is-loosenedsufliciently to engage the rail-flange, after which the binding-screw is properly tightened and a most rigid and lasting connection between the rails and the ties is obtained.

Owing to the fact of there being no necessity for bolt or screw openings in the railflange or the ties, these clamps may be utilized in the tearing up of old tracks and the relaying of new ones.

Having described my invention, I claim 1. In a rail fastener for uniting rails to cross-ties, a clamp having a suitable opening for the tie, a lip projecting from said clamp and embracing the upper surface of the railflange, and a screw penetrating the top of said clamp and engaging the upper side of the rail, and effecting three points of contact when the device is rigidly secured in position.

2. A clamp for fastening rails to metallic ties consisting of a member having an opening therein to receive the tie, the lower surface of said opening being of tapering form, a lip projecting from one side of said member and engaging the rail-fiange, and a screw penetrating the upper end of said. clamp and engaging the tie.

3. In a fastener for rails, a clamp having a suitable opening to receive the tie, a screw passing through the upper portion of said clamp in alinement with the center of the tieopening, a lip extending on one side of said screw and adapted to project over the railfiange, the lower surface of the tie-opening in said clamp being of tapering form to provide a bearing-point between the lower side of the tie and the bottom of the clamp which engages said tie at a point between the contact-point of the screw and the tie, and the contact-point of the clamp and the rail-flange.

4. A clamp for securing rails to metallic cross-ties, the same having a T-shaped opening to receive the rail, the lower surface of said opening being of tapering form to engage the bottom of the rail at one side of the clamp,
