NUT-LOCK- Specification of Letters Patent.

Patented April 23, 1907.

Application filed July '7, 1906. Serial No. 825,164..

To aZZ whom it may concern:

Be it known that I, THOMAS R. I'IORN, a citizen of the United States, residing at Marquette, in the county of Marquette, State of Michigan, have invented certain new and useful Improvements in Nut-Locks; and I do hereby 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.

This invention has relation to nut-locks for holding a series of nuts on the bolts extending through the fish-plates of a railway-rail against turning back or becoming loose.

It is the object of my invention to provide a nut-lock of the class mentioned that operates alone to keep the nuts from turning and will not interfere with ormodify the spiking of the rails and fish-plates to the ties.

It is a further object of the invention to provide means for keeping the nut-lock plate from tipping either up or down from its correct position.

The nature of the invention is to be ascertained from the foregoing statements in view of the annexed drawings, forming a part of this specification, of which drawings Figure 1 is a side elevation. Fig. 2 is a section on line 2 2 of Fig. 1.

The same figures of reference designate the same parts or features, as the case may be, wherever they occur.

- In the drawings, 5 5 designate the ends of the'two rails joined by the means represented in connection therewith. 6 6 are the fishplates. 7 and 8 are respectively the bolts and nuts securing the fish-plates to the web of the rails. Spikes 9 are employed for securing the inclined flanges of the base of the rails and fish-plates to the railway-ties 10. All of the said parts are of usual construction and arrangement.

11 is the nutlocking plate constituting a part of my improvements. This plate is made as light as is consistent with the strength required of it to perform its necessary functions. The said plate 11 is provided on its upper edge with a straight vertical 12, which fits against one of the flat sides of each of the nuts 8 underneath the same. From the vertical 12, the plate 11 is inclined downward and outwardly, covering the inclined flanges of the fish-plate and rails as well as the usual spikesthat secure the rails and fish-plate to the ties. line where the heads of the aforesaid spikes are located the nut-locking plate 11 is pro and forming the lower outer edge of the nut' locking plate 11 the latter is provided with a ledge 16, by which the last-mentioned plate is spiked to the ties 10 through the medium of additional spikes 20, all as is clearly represented in Fig. 1 of the drawings. By the means stated it will be seen that the means for securing the nut-locking plate in position are entirely independent of the spikes which fasten the rails and fish-plate to the ties, so that the latter can be constructed and used entirely with respect to fastening down the rails and fish-plates and need not be in any way modified because of the presence of the locking-plate.

18 designates a small plate, secured by screws or threaded bolts tapped through its edge and surrounding parts to the under side of the said elements to hold the nut-locking plate from tipping either up or down, which its outer edge is inclined to do under some circumstances. Said plate is arranged at a point between'two ties, so that it does not interfere with the construction or arrangement of other parts.

What is claimed as the invention is A nut-lock for the series of nuts at a railway-rail joint consisting of the combination with the said nuts, the rails, ties, and fishplate, of the nut-locking plate having a flange on its upper side fitted againsta flat side of the nuts underneath the same, and extending over the base-flanges of the rails, fish-plate, and heads of the rail-securing spikes, the nutlocking plate being provided with a right an gular rib along the line of the spike-heads, said rib being undergrooved for the reception of the spike-heads and having a horizontal ledge on its outer edge whereby it is independently spiked to the ties.

In testimonyv whereof I a'l'liX my signature in presence of two witnesses.

THOMAS R. HORN.
