NUT-LOCK.
SPECIFICATION forming part of Letters Patent No. 305,051, dated September 16.1884.
Application filed February 5, 1884. (No model.)4
?) all whom it may concern:
Be it known that I, GEORGE I). CRAGIN, a citizen of the United States, residing at'Ada, in the county of Norman and State of Minnesota, haveinvented certain new and useful Improvements in Nut-Locks, of which the following is a specification, reference being had therein to the accompanying drawings.
My invention relates to improvements in nut-locks of the class known as top nutlocks; and the invention consists in an improved construction and arrangement of the parts, whereby the nut is more effectively locked against accidental turning or displacement than by other devices of this class with which I am acquainted.
In its general features my nut-lock consists of a plain threaded and slotted bolt, a nut having a locking projection, a spring-washer interposed between the nut and the fish-plate or other surface, a rabbeted key fitting the slot in the bolt and engaging with the projection on the nut, and having also a locking projection, for purposes hereinafter set forth. These general features will be more fully hereinafter' described in connection with the drawings,in
which- Figure 1 is a sectional view of the web of a railway-rail and an elevation of my nut-lock in connection therewith. Fig. 2 is a view of the spring-washer. Fig. 3 is a partial section of the nut-lock shown in Fig. 1. Figs. 4 to 12', inclusive, represent various modifications, which will be hereinafter specifically described.
A represents an ordinary threaded bolt, in which is formed a slot, a, having parallel sides and plane faces.
B is nut of square or polygonal form. In the process of manufacturing the nut a proj ection, b, is formed on its face, which I prefer to make of circular form, as shown in all the figures, save Fig. 5, whereit extends only partly around the nut. In Figs. 1, 3, and 4 the projections are shown in addition as of conical shape.
The key G is shown clearly in Fig. 3. It is adapted to pass transversely through the slot a, and is provided with a stopping and gaging projection, d, which catches over the edge ofthe slot, and stops the key and holds it in the right position in the slot to present its rabbet c to the projection Z) of the nut when the nut is turned outward to lock it and the keytogether. At that edge of the key which is in proximity to the nut is formed a rabbet, c, which corresponds, substantially, to the shape of the projection on the nut. Thus in Figs. 1, 3, and et it is shown as having opposing inclines, which tit the interior conical projection of the nut.
In the modification shown in Fig. i the projection Z on the nut is a conical exterior ange. The key has rabbets c c, which enter into the space withinA the projection of the nut.
In Fig. 5 the projection bis in the shape of the are of a circle, and does not extend entirely around the nut. The rabbet c of the keyin this forni is at the end of the inner edge of the key.
In Fig. 6 the construction is substantially similar, except that the projection b of the nut is a complete circular flange. The key is precisely similar to that shown in Fig. 5.
Fig. 7 shows a form of key adapted to the :nutv shown in Fig. 11, and will be hereinafter described.
In Fig. 12 the projection b is the side of the nut, and in this instance is in acircular groove around the angular nut. VIn this forni that portion of the key which passes through the and the projection d. The opposite end has the rabbet c, which bears firmly against the projection b, being the side of the nut.
In Fig. 8 the projection b iiares outwardly from the face of the nut. rlhe slot ci in the bolt has curved or slightlyangular sides, and
the key having the rabbet c, with which the i projection b engages, is shaped to fit the peculiar contour of the edge of the slot. The key has the usual gagging-stop, d. In Fig. 9 the projection b is an exterior iiange.
In Fig. 10 the projection b is also a iiange,
slot is of ordinary form, having straight edges IOO surface is inserted aspringwaslier, D7 (shown in Fig. 2,) which tends to press the nut out Ward.
In the operation of the device the nut is iirst screwed tightly up toward the plate or bar, forcing the spring inward. The key is then inserted in the slot until checked by the stop d, and the nut is given a slight backward turn sufficient to crowd the projection?) into engagement with the rabbeted key to force the key against the side of the slot.
To operate the modification of Fig. l2, insert that end of the key which has the projecv tion cl iirst into and through the slot of the bolt until the rabbet at the other end of the key is engaged by the projection Z1 on the side of the nut. Then screw the nut back until its outer plane edge abuts against the outer wall of the slot in the bolt and the projection d overlaps the bolt-thread. Any tendency of the nut to unscrew simply forces the locking parts into closer en gagement-a result to which the spring-pressure contributes.
Having thus described my inventio11,wl1at l claim as new, and desire to secure by Letters Patent, is-
l. In anat-lock, the combination of a slotted bolt, a nut having a projection on its face, a rabbeted key, and a spring-washer7 substantially as described.
2. In a nut-lock, the combination of a bolt having` theslot a, the nut having a projection on its face, the rabbeted key having the projection d, and a sp1ing-v'ashe1, substantially as'described. t
3. The combination of a slotted bolt, a nut having a circular projection from its face, and a rabbeted key having; a stopping and gagng projection, substantially as described.
In testimony whereof Iliave affixed my sig- 4o nature in presence of two witnesses.
GEORGE P. CRAGIN.
