NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 693,154, dated February 11, 1902. Application filed March 5,1901. Serial No. 49,691. (No model.)

To all whom, it may concern.-

Be it known that we, FRED WILLIAM RIECK and EDWARD WILLIAM EUGE, citizens of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Nut-Locks, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to nut-locks; and the object thereof is to provide an improved device of this class which will also serve to cover and shield the nut and the threads of the bolt on which the nut'is .placed, and thus protect both the nut and the threads of the bolt; and with this and other objects in view the invention consists in a device of the class specified constructed as hereinafter described and claimed.

In the drawings forming part of this specification we have shown our improvement ap plied to the fish-plates used for connecting the railway-rails of a railway-track, and the invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of our improvement are designated by the same reference characters in each of the views, and in which Figure 1 is a transverse section of a railway-rail provided with the usual fish-plates and showing our improvement applied thereto; Fig. 2, a partial horizontal section on the line 2 2 of Fig. 1; Fig. 3, an outside view of a detail of the nut-lock, and Fig. 4 an inside view thereof.

In the drawings forming part of this specification we have shown in Figs. 1 and 2 a railway-rail comprising the usual central vertical web 5, the top bearing portion 6, and the base-plate or side flanges 7, and we have also shown in Figs. 1 and 2 the usual fishplates 9 and 10, which are used in binding two of the railway-rails together, and in the practice of our invention we provide a nutlock and nut-protector comprisingan inner washer-plate 11 and an outer casing 12, which is open at its inner side, and the sides of the washer-plate 11 and the inner side walls of the casing 12 are beveled, so that said washerplate fits in said casing, as clearly shown in the drawings.

The outer surface of the washer-plate 11 is corrugated transversely, so as to form transverse depressions 13 and corresponding projecting or thickened portions 14, which are provided alternately with cylindrical members 15 in the form of bolts, which are preferably formed integrally therewith.

The casing 12 is oblong in form, as is also the washer-plate 11, and is provided with internal rectangular spaces 16, adapted to receive thenuts 17 ofthe bolts 18, by which the fish-plates are bound to the rails, said bolts being also passed through the washerplate 11, as is clearly shown, and the outer surface of the casing 12 is preferably provided with transverse recesses 19 at points which'correspond with the outwardly-directed or thickened portions 14 of the washer-plate -11, and the cylindrical or bolt-shaped members 15 of said washer-plate pass outwardly through the casing 12 at these points, and wedge-shaped key-pins 20 are passed therethrough, so as to bind the casing 12 to the washer-plate ll.

The holes or openings in the fish-plates and 'in the plate 11, through which the bolts 18 are passed, are made oblongin form, as shown at 21, so as to permit of expansion and contraction, and the nuts 17 of the bolts 18 are angular in form and designed to fit in the corresponding internal rectangular spaces 16 in' the casing 12, which prevents said nuts from turning, and the said nuts and the threaded ends of said bolts are entirely inclosed by the plate 11 and the casing 12, which together make up our improved nut-lock and nut-protector.

Our invention is not limited to the exact' form of the parts or members 11 and 12 herein shown and described, and changes in and modifications of the shape and construction of these parts may be made without departing from the spirit of our invention or sacrificing its advantages. cut that this device may be applied to bolts and nuts wherever such devices are required, and our invention is not limited to the appli cation thereof to the fish-plates of railwayrails, as herein shown and described.

It will also be apparthe edges of the casing lying in the depressions or seats of the Washer-plate, and wedgepins run through the slots of the bolt-like projections of the washer-plate for retaining the casing in position as and for the purpose described.

In testimony that we claim the foregoing as our invention We have signed our names, in presence of the subscribing witnesses, this 19th day of February, 1901.
