UNITED STATES PATENT OFFICE.
TO B. T.BOU1VIA, OF LYNNVILLE, IOWA. 1
Nor-Loom Specification of Letters Patent.
Patented Nov. 2. 1920.
Application filed January 24, 1920. SeriaI No. 353,719.
To all whom it may concern:
Be it known that I, Conunmus VAN Gnnnnnniv, a citizen of the United States of America, and resident of Sully, Jasper county, Iowa, have invented a new and useful Nut-Lock, of which the following is a specification.
The object of this invention is to provide an improved construction for nuts and keeper, whereby said nuts may be locked to bolts and against rotation thereon.
lily invention has for a further object the provision of an improved construction for a keeper whereby said keeper may be held on a nut during the operation of locking said nut to a bolt.
My invention consists in the construction, arrangement and combination of elements hereinafter set. forth, pointed out in the claims and illustrated by the accompanying drawing, in which Figure 1 is an end view and Fig. 2 a side elevation of a bolt, nut and keeper embodying my invention. Fig. 3 is a diagram of a blank from which the keeper is formed.
Fig. 41 an end view and Fig. 5 is a side elevation of a. bolt. nut and keeper embodying a modified form of construction of the keeper and its relation to the nut. Fig. 6 is a diagram of a blank from which the keeper of Figs. 4t and 5 is formed.
In the cm'istruction of the device as shown in Figs. 1, 2 and 3. the numeral 10 designates a bolt and 11 designates a nut screwed on said bolt. The bolt 10 is formed with a diametrical. slot 12 in one. end and intersecting the thread thereof. A keeper 13 is formed from a blank shown in Fig. 3, which blank is rectangular in outline and has a hole 14 therein. The hole 1 1 is longer than it is wide and is square at one end and semicircular at the other end. The hole 141 is located with its square end in proximity to one end of the keeper. The keeper 13 is curved on differentarcs in its end portions, the smaller are being adjacent to and compassing the square end of the hole 1 1, and
that portion of the keeper between said square end of the hole and the adjacent end margin of the blank is plane. The larger arc encompasses the round end of the hole 1 1 and a portion of the end of the blank adjacent thereto is plane. The plane portions of the keeper are respectively designated by the numerals 15 and 16. The nut 11 is formed with a diametrical slot 17 intersecting the bore of said nut and adapted to aline at times with the slot 12 in the bolt. The nut 11 also is formed with a groovelS in one face and parallel in length with and at right angles in depth to the'slot 17.
In practical use, the nut 11 is seated on the bolt 10 to the desired degree to hold any objects between the nut and the head of the bolt and with the slot 17 in alinement with the slot 12. Then the keeper 13 is mounted as shown with its end portion 15 in the slots 12 and 17 and is bent on the arcs so that its opposite end portion 16 enters and remains in the groove 18 of the nut. The hole 14. accommodates any projecting threaded portion of the bolt freely. In the position shown, the keeper prevents any rotation of the nut 11 on the bolt 10 and said keeper usually is of suiiicient width to prevent by friction in the groove 18. any accidental removal endwise from said groove.
Sometimes. when the nut is of small size,
there is a tendency of the keeper to work out 7 of the groove by endwise movement and to obviate this trouble a slight modification is put in the keeper as follows: The keeper 13 (Figs. 4, 5 and 6) is of slightly greater width at one end than at the other end and is formed with a notch 19 adjacent to the square end of the hole 1 1, thus forming a relatively narrow bar 15 adapted to enter the alining slots 12 and 17, together with studs 20, 21 at each end of the notch 19 adapted to overlap on the sides of the nut 11 The keeper is held in contact with the bolt and nut by engagement of the opposite end in the groove, and the overlapping studs 20, 21 hold the entire keeper from any endwise movement out of the groove or slots.
Either form of keeper may readily be removed by inserting a tool between one end thereof and the slotted face of the nut and prying said keeper outwardly and free from the groove 18.
I claim as my invention-- 1. A. nut lock comprising a bolt formed with a diametrical slot in its threaded end. a nut adapted to be screwed thereon and formed with a diametrical slot adapted to register and aline with the first slot and also formed with a groove in one face. and a keeper substantially agreeing in width with the nut and formedwith one plane end portion adapted to enter the alining slots and formed with another plane end portion adapted to enter said groove.
'2. A nut lock comprising a bolt formed with a diametrical slot, in its threaded end, a nut adapted to be screwed thereon and formed with a diametrical slot adapted to register and aline with the first slot and alsoforrned with a groove in one face, said groove being parallel in length with and at right angles in depth to said slot in the nut, and a keeper substantially agreeing in width with said nut and formed with a hole to accommodate the threaded end of the bolt,
said keeper being bent between its ends, one end portion of thekeeper being adapted to enter the registering slots and the other end portion of the keeper being adapted to enter the groove and extending across the nut.
3. A nut lock comprising an end-slotted bolt, a nut formed with an end slot adapted to register with the bolt-slot, and also formed with a side-slot, and a keeper having an end portion adapted to enter the registering end slots and having an end portionadapted to enter the side-slot, said keeper also being formed with corner studs overlapping sides of the nut at ends of said end slot.
Signed at Sully, in the county of Jasper and State of Iowa, this 20 day of November, 1919.
