8'Claims, (Cl. .3 1.50.)
This invention relates to spanner wrenches, and particularly to a wrench designed to accommodate the lug type of sleeve or coupling-nuts such as used in coupling-s for joining together There-are inpieces of fire hose, oil hose, etc.- common use three general types of lug type cou pling nuts, namely the cylindrical sleeve nut having-two diametrically opposed pin lugs such as used in fire hose couplings, the polygonal type of coupling nuts which a'regprincipally octagonal shapedwith relatively wide diametrically opposed lugs, and.also the cylindrical or sleeve coupling with relatively wide diametrically opposed-lugs.-
The principal object of this. invention is the constructionof a simpleand efficient wrench formed in one piece, and designedtoaccommm date several different-sizes of coupling nuts of' like design of the. types. mentioned above...for facilitating the tightening or loosening of the same in couplingunions. v
Aiurther object of this invention is toprovidea wrench of the aboven'ature having means wherein the headend ofthe wrench is held upon] the nut withoutthe need .cithe operatorhaving to manually support, the entireweightof' the same.
A still further object is to provideazwrench having acommon fulcrumtoengag the several sizes-and types of coupling;nutsfonwhichthe wrenchis adapted at. a commonpoint and fur therformed. with a series of 1 independentsec-- tions to accommodate the surfaces of the-different sizes of couplings at a position-:sufficiently removed from; the fulcrum. of" the wrench. to
assure a goodturning grip...
The full nature of thisflinventions along with other objects and: various advantages thereofwill be'more apparent from a consideration of the following description when read in connec-' tion with'the accompanying drawings,in which sizes of the octagonal type of coupling lugnuts shown in dot-and-dash outline, and
Fig. 6 is a viewsimilar to Fig. 5 showing'the head part of the spanner wrench modifiedto accommodate a plurality of the cylindrical or sleeve type of coupling lug nuts.
Referring tothe drawings in which like numerals designate like parts throughout the sev eral views; the numeral l0 indicates a longitudi'nal bar'or operating handle of the Wrench, having a generally curved head partlZ integrally formed at one end thereof and which head part IZterminates in a hooked portion M. The concave edge portion of the head part l2constitutes the working face ofthe wrench and generally is indicated by the numeral 13. The major'portion of the head l2 ispreferably locatedto one side of the longitudinal axis of the-handle l0 and the working face l3 lies entirely toone side 'ofsaid handle axis for convenience in operating the wrench; and for accommodating in a like manner the various sizes of coupling nuts 'for which the wrench is adapted." Thehookedportion I4 'is' provided with a pair of spaced' sidef walls !6 cast integrally on opposite sides thereof and which Walls" in conjunction with the base wall l8 of the hooked portion define a socket 20 opening toward the handle portion of the wrench. The socket is proportioned to accom- Fig. l is a=frontelevational viewof the spanner wrench embodying theinvention; Y
Fig. 2 is a longitudinal end viewof the same looking into the frontpart of the wrench'or'thetop endview according to Fig. 1.
Fig. 3 is an end View looking into th e wrench from the handle end of the same. Fig; 4'is a sectional view through the hooked end of the wrench taken along the line 4'-4oij Fig. 1.
Fig. 5 is a-view similar to Fig; l showingprincipally the head portion of the wrench ion a slightly'enlarged scale and illustratingthe manner'in which-it is-usedwith the several different modate the various sizes of lugs 22 forming an f integral and opposed projecting members of their respective coupling nuts 24 as best shown in-dot and-dashoutline inFig. 5., As here shownthe wrench is designed to accommodate theoctagonal lug type coupling nut, but it is to be understood that this wrench can be, properly delineated to accommodate the other types of coupling nuts stated in the preamble of the specificationand as hereinafter will be more fully explained. I,
In order to provide a common pivot-point or fulcrum means about which the. Wrench may be-swu-ng relative to the coupling nut when bring- 7 ing the wrench into operating position, the outer end of thebase wall I8 of the socket 20 joins into the outer adjacent edge of the hooked portion at a relatively sharp angle which is'in thedrawings shown as approximately and it couldbe an angle of less degrees. This point ofmerger of the. Q .base Wall I8 and the outer surface of the hooked portionisconsidered the common fulcrum point of the wrench and is designated by the letter F..
The fulcrum F conveniently. engages into the angle where.v one end of the coupling nut lug 22. merges withthe immediate adjacent fiat of the.
coupling nut 24 and about which point the wrench swings into operating position. It is to be noted that the outer face of the hooked portion lies in a common plane with the free edges of the side walls lli and that this plane is disposed at an acute angle to the longitudinal axis of the handle It]. By this particular arrangement of the parts to the handle axis it allows the wrench to engage securely and uniformly the several sizes of couplings.
The socket base wall l8 opposite from the fulcrum point F curves outwardly from the socket 20 and gradually merges into the working face l3 of the Wrench, which face iii in turn is broken up into a series of flat stepped sections 26, each of which stepped sections 26 are connected with each other by upwardly off-set planes 28. The outermost plane 28constitutes the inner face of an upstanding lug 30 that defines the outer end of the general working face l3 of the spanner wrench. The stepped sections 26 with their, complementary off-set planes 28 constitute independent surfaces that engage a portion of at least two adjacent angular flats of the nut next to the lug 22 Opposite from the'one that the hooked, portion 14 of the wrench engages for assuring a suitablegrip upon the nut for tuming the same: Furthenthe complementary oflset planes 28 of each stepped section 26 in engaging a portion of the immediate nut flat. adjacent the opposite lug from which the wrench fulcrumsserves as a stopmeans topreclude the wrench from slipping off the nut indcase a force is applied to the, handle axis and toward the headend;
Por -conveniencein storing the wrench when not in use the end of the handle I opposite from the-head part 12 may be provided with an opening ,32 byrneans of which the wrench may be hung upon a hook. r v
The modified form of wrench illustrated in Fig; 6 is identical in all respects to the first form described except that the-working face l3a of the head part l2a is divided into several-independent arcuate surfaces-26a corresponding in a shape to a portion; of the cylindrical shape of the sleeve-type lug nut 24a for which-this wrench V particularly is-adapted. j
It will be further apparent that this wrench is also adaptable to fit thecylindrical or sleeve type 01' coupling; nuts provided with pin lugs of the invention. a v a We claim for our invention: r
