A. FLORAN DE VILLEPIGUE, OF NEV YORK, AND LOUIS G. DE BERTR AM, OF BROOKLYN, NEXV YORK.
SPECIFICATION forming part of Letters Patent No. 417,235, dated December 17, 1889.
Application filed March 25, 1889- Serial No. 304,616. (No model.)
To all whom it may concern:
Be it knbwn that we, A. FLORAN DE VILLE- PIGUE, a resident of the city of New York, in the county and State of New York, and LOUIS G. DE BERTRAM, of Brooklyn, Kings county, and State of New York, have invented a certain new and useful Improvement in Bolts, of which the following is a specification.
This invention relates particularly to bolts of the kind which are used in conjunction with railways for securing abutting rails and overlapping fish-plates together.
The object of the improvement is to provide a bolt which will be simple, cheap, easy to operate, and not liable to become loosened by passing trains.
WVe will describe a bolt embodying our improvement and then point out the novel features in claims.
In the accompanying drawings, Figure 1 is a transverse section of a railway-rail, two fishplates embracing the same, and a bolt embodying our improvement combined therewith. Fig. 2 is a horizontal section taken at the line of the axis of the bolt. Fig. 3 is an end view of the bolt.
Similar letters of reference designate corresponding parts in all the figures.
A designates a railway-rail. It may be of the usual or any suitable form.
B B designate two fish-plates embracing the rail. They extend parallel with the rail, in the usual manner, and they fit between the foot of the rail and the head thereof. They are intended to form a spliced joint between two abutting rail-sections in a well-known manner.
O designates a bolt. It may be of the usual cylindric form. At one end it may have an ordinary head. It is inserted through holes in the fish-plates and the rail, and if provided with an ordinary head, as suggested, the head will bear against the exterior of one of the fish-plates. Instead of having an ordinary head, we have shown it as provided with a transverse slot 0 and as having a key or bar D inserted in such slot. It will be seen that the fish-plate B has a longitudinal groove in it and that the key or bar fits in said groove. The engagement of the key or bar with the c an eccentric G is fitted.
groove in this fislrplate will prevent "the bolt from turning. At the other end the bolt is provided with a transverse slot 0'. In this is fitted beyond the fish-plate B a securingpiece E. This is shown as consisting of a plate having the outer edge e of the main portion inclined. Owing to this the main portion is made to taper. The taper is in the present instance wholly due to the inclined edge e, the opposite edge 6 being straight and parallel with the fish plate. Beyond the smaller end of the tapering main portion there is a hook-shaped extension at Upon the end of the bolt C beyond the slot It is free to move rotarily. It is shown as made in the form of a plate. It may be secured in position upon the bolt iii any desired manner. In the present instance it is retained by slipping under the hook shaped extension 6 It may be slipped under the hook-shaped extension before being slipped onto the bolt. The shank portion of this eccentric is bent outwardly, so as to approximately correspond with the inclined edge e of the securing-piece, and, owing to this, the eccentric may be turned around without interference from the securing-piece. The operative edge of the eccentric bears against the l1ook-shaped extension of the securing-piece; hence by rotating the eccentric by grasping its shank or by tapping the shank with a hammer, or by application of the req uisite force in any other manner, the eccentric will be made to draw the securing-piece through the slot 0 of the bolt, and, owing to the inclined edge of the securing-piece, this will result in drawing the bolt farther through the fish-plates and rail. The fish-plates and rail will therefore be very tightly clamped together. The eccentric when adjusted will not be liable to become loose.
It will be seen that this bolt is very simple and not liable to get out of order.
The bolt is applicable not alone to railways, but to machinery generally.
-What we claim as our invention, and desire to secure by Letters Patent, is
1. The combination, with a slotted bolt, of a securing-piece having an inclined edge fitting in the slot of the bolt and an eccentric for operatingthe securing-piece,substantially and having an inclined edge, a hook-shaped IO as Specified. extension, and an eccentric for operating the 2. The combination, with a slotted bolt, of securing-piece, substantially as specified. a securing-piece having an inclined edge fitting in the slot of the bolt and an eccentric g P mounted to rotate upon the bolt for operating J the securing-piece, substantially as specified.
