Passing through the fish-plates and declare the following to be a full, clear, and the web of the rails are the ordinary bolts 3. exact description of the invention, such as will Screwing onto said bolts are the nuts 4. For

Io enable others skilled in the art to which it apthe purpose of preventing said nuts from pertains to make and use the same, reference turning on the bolts after they have been set being had to the accompanying drawings, there is employed a locking-barmade in two and to the figures of reference marked theresections 5 and 6, joined at the center. To on, which form a part of this specification. connect the meeting ends of said bar, section 5 This invention relates to nut-locks, and par- 5 is provided in the inner end thereof with a ticularly to the locking of nuts of the bolts mortise7. Formedin the opposite wallsofsaid that pass through the fish-plates which unite mortise are the inclined ways 8, which extend the ends of railway-rails; and it consists in the downwardly and terminate in a straight lower construction and arrangement of parts hereinportion 9, as shown in Fig. 2. Projecting from 20 after fully set forth, and pointed out particuthe inner end of the section 6 of the locking-bar larl y in the claims. is a tenon 1 (),having pins 11 extending laterally The object of the invention is to provide therefrom, the opposite ends of which are simple and efiicient means applicable to nuts adapted to engage in the opposedinclined ways in common use upon railway-bolts whereby 8 as the tenon is placed in said mortise from the 2 5 said nuts may be prevented from turning by top. As the parts are forced together the pins reason of the jar and vibration incident to the travel down the inclined ways and draw the passage of a train along the track, the arends of the sections of the bar together until rangement being such as to enable the locking the straight portion 9 of said ways is encoundevice to be readily placed upon the nuts and tered, which the ends of the pins enter and 3 quickly and easily removed. lock the sections of the bar against longitudi- The above object is attained by the strucnal separation. Upon the top of the tenon is ture illustrated in the accompanying drawings, a cap 12, which closes the mortise-opening.

Fig. 5 is a fragmentary view in dehooks 15, which enter recesses in the ends of 45 tail showing the manner in which the hook at the fish-plate and lock the sections of said bar the end of the locking-bar engages in a recess from lateral displacement. In placing this of the fish-plate. Fig. 6 is a fragmentary locking-bar upon the nuts the hooks at the ends are engaged in the recesses in the fish-plate and the tenon of one section inserted from the top in the mortise of the other section and said parts forced one into the other,which operation draws them together longitudinally, causing the hooks to engage firmly in the recesses of the fish-plate and the notches to engage the nuts in a manner to prevent them from turning, as shown in Fig. 1. To remove the locking-bar, the meeting ends ofthe sections thereof aredisengaged by raising the inner end of section 6 until the ends of the pin engage the inclined slot, When a further upward movement of said section will cause a longitudinal separation of the sections as the tenon is Withdrawn from the mortise, thereby relieving the hooks at the ends of said sections and enabling them to be removed.

Having thus fully set forth our invention, What We claim as new, and desire to secure by Letters Patent, is

1. In a nut-lock, the combination With the bolts and nuts, of a two-part locking-bar having open notches in its under edge to engage said nuts, the meeting ends of the parts of said bar having engaging interlocking members for detachably locking said parts together.

2. In a nut-lock, the combination with the bolts and nuts, oi' the two-part locking-bar having open inclined notches to engage the nuts, each of said parts having a member at the end adapted to engage the fish-plate and said parts having integral interlocking members at the meeting ends for detachably uniting them.

3. In a nut-lock, the combination With the bolts and nuts, of the two-part locking-bar, each part having a hook at the end adapted to engage the fish-plate, there being in one part a mortise and upon the other part a tenon adapted to enter said mortise, there being in the Wall of the mortise an inclined Way and a pin in the tenon adapted to engage in said Way, the under side of said locking-bar having notches adapted to engage over the nuts.

In testimony whereof We sign this specification in the presence of two Witnesses.
