' NUT v Filed Jan. 2, 1930 7 un g 6 zillml INVENTOR WITNESSES W E. Wells 9k ATTORNEYS Patented June 28, 1932 NT- QFFHCE NUT implication filed Junusry 2, 1980. Serial No. 418,068.
This invention relates generally to the class of hsrdwere, end has particular reference to an improved nut for threadedly enguging s threaded stem, bolt, spindle or the like.
As an oh'ect, the invention comprehends an improve nut which is constructed in such s manner as to he engaged by s wrench with greater fecility endmore security than ordinery types of nuts that are now in general use end on the market.
The invention further aims to provide e nut which may be turned by e wrench while imparting lesser strains and stresses to the wrench and in which the nut may be disposed in closer proximity to a, well or corner of structure then the usual type or" nuts.
More specifically, the invention contempletes nut having non-parallel side faces end truncated spores at the juncture of seid side faces, which truncated spores are formed with wrench receiving recesses within which least two of said recesses, the wrench preferehly engage for turning the nut.
@ther objects of the invention reside in t e comparative simplicity of construction mode of use of the nut, the economy with v rich it he produced end the general eiuciency derived therefrom.
With shove recited and other objects view, reference is to the following descr ntion end smompenying drawing, in which there is exhibited one example or emhodimen't the invention, while the claims define tne sctuul scope of the sense n the i as side view t erect,
cross sectional view ti erer oximutely on the line in- S in i lgure l.
, Referring to the drawing" by characters of reference, nut consists of at body which is provided with e plurality of major side feces disposed in non-parallel relution end en single to such other. Preferably, the
nut is in :lorm of uneouiluterel triungle us illustrated, elthough is to he understood that it is not necessarily restricted to this shape. The nut body 5 is formed with truncated upexes 7 which present minor side faces disposed parallel to and opposite the major faces of the nut, and said truncated spexes 7 are formed with wrench jaw receiving recesses or notches 8 which preferably exceed a semi-circle and which are desi ned to re ceive the similarly formed jaws oi a wrench. ln practice, at least two of said recesses will preferubly receive a, pair of wrench jaws for the purpose of turning the nut and, consequently, the Wrench shank proper will engage with one of the major side faces 6 whereby a free point engagement is established at at point at one side of the axis of rotstion of the nut, thus securely establishing a connection between: the wrench and the nut end subjecting the wrench to lesser strain or stress than is produced on a wrench with the ordinary types of nuts. lt will he further apparent that due to the shape of the nut, it may be installed on a bolt or threaded stem which is set closer to a, well, corner or angle of a structure. it is further apparent that F the notches or recesses 8 which extend com pletely throughout the depth or thicliness of the nut, may be employed to receive therethrough u pin screw or other device en" chored in s stationery structure which will serve to lock the nut against retrograde movement,
il/hut is claimed is:
i. As a new erticle of msnuilscture, a nut having non-parallel side feces end truncated spores the juncture of the side feces, seid truncated spores having wrench receiving recesses,
As new article 01" manufacture,
liuving nonperellel side and truncated upexes at the juncture of the side feces, truncated spares having wrench receiving; recesses extending throughout the thiclniess oi the nut.
3. As s new article of manufacture, it nut in the form of en equilateral triangle having truncated speues'provided with wrench receiving recesses.
l. As anew article of manufacture, it nut in the form of nu equilsterul triangle hsv- 2 naemsee ing truncated apexes provided with wrench recelvmg recesses exceedmg a seml-cn'cle.
5. As a new artlcle of manufacture, a nut in the form of an equilateral triangle having truncated a exes presenting minor faces parallel to t e pp0s1te maJor faces of the nut, said minor faces provided with wrench receiving recesses.
