T o rzZZ ywhom t may concern.'`
Bc it known that I, @Hannes Hermann, a citizen of the United States, residing` at New York. in the county of New York and State ot New York, have invented certain new and use-Ful improvements in Nut and Bolt-Head llfrenchcs; and do hereby declare the following to he a ull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relatos to nut and holthead wrenches and it has for an object to provide a jaw formation by which each end ot a double ended wrench may have a capacity ttor a plurality of sizes of nuts or holtheads. i
A `further object of this invention is the provision or" a wrench head having jaws formed to accommodate several sizes of nuts or holtheads, and having said jaws so formed as to have certain parts thereof reinforce those parts upon which strain is exerted when in use.
A further object is the provisionof a wrench head having jaws formed therein and having` the adjacent faces of said jaws in stepped formation having corresponding steps on each of the jaws to present sockets hut having the steps of each of the jaws o'- set varyingly, in varyingly substantial pan allelism so that by two or three sets of step faces, three or four sizes of nuts or holtheads may he accommodated. j
Further objects will he apparent from the following specification, appended claims and drawings thereof, in which,
Figure 1 is a perspective view oit the wrench showing the 'features of this invention incorporated therein,
Fig. 2 is an end eleva-tion thereof,
Fig. 3 shows a slightly modified form, and
Fig. a is a perspective view of a mode of using the wrench.
Referring to the drawings in which the several features of this invention are clearly shown, indicates a handle portion oi a double-ended wrench having the wrench heads 11 and 12 formed at the opposite ends F the handle member. Each of these heads is formed into the jaws 13 and 11i which have their adjacent faces-stepped as at 5. These jaws have corresponding1 portions and have the steps oiiset to a greater extent at one side than at the other, as shown clearly in Fig. 2, so as to allow the faces 16, 17, 18
to form the faces 22, 23, 24, 25
and 19 respectively to he used in gripping nuts or holt-heads in various combinations. That is, for one size ofbolt-head having a transverse dimension indicated at C, the faces 16 L ud 17 are used, foran intermediate 4size indicated bv B, the faces 18 and 19 are used, hut for the smallest sizeindicated at Af the faces 17 and 18 are used, so it is thereby seen that three different sizes of nuts may he gripped by the wrench by portions of the jaws. As shown in Figs. 1 and 2, it is possible for a single wrench with two sets of jaws in staggered relation to accommodate siX sizes of nuts. As to Figs. 1 and 2 it may also he noted, the weakest portion ot a wrench aw is on lines fvwm-an at the junction of the jaw faces and crotch and the weakness of this line on aw 13 when either of the faces 16 or 18 is used is compensated for by the material forming the other face, as the case may he. and similarly, the weakness of 'the jaw 111 is compensated for by the metal forming either of the faces 17 or 19, which is not being used. This ena-hlesa maximum strength jaw with a minimum of bulk and metal, a saving in quantity production, and a greater manipulative ease in restricted spaces and corners. v The offsets which produce the stenpedfor- 'mation of the 'faces 1G, 17, 18 an-d 19 are indicated at 15a and 15b, and the curved, orv
otherwise formed faces, which connect the ends of the faces 15, 17, 18 and 19 across the crotch may he identified by the characters 1Ga and 18", respectively. The oii'sets '15a and 15b continue between the curved faces 16a and 18, to a common meeting point which occurs at the intersection of the curved planes of the faces A16a and 18a. These oii'sets are inverted relatively on the opposite sides of the meeting point. t may further he noted that the crotch', curved faces 16L and 181 are eccentric with respect to each other in the separate companion sets ot faces. v l l When the Jfaces 17 and 18 are being used, the tend eney oi. the strain exerted upon the wrench to twist the jaws land 111- occurf ring1 in the contact of one orP the faces 17 or 18 is countcra'cted hy the other 'of the faces so it is seen that the wrench may he equally as convenient in use for any of the several sizes.
ln Fig. 3, the jaws 20 and 21 are steppedl vand 26. ln
this type, the faces 22 and 23 receive the largest size nut, the feces und 2 t size nut, the feces 25 and the i en ceeding standard size of nut9 while tie faces 2i and will occonnnodete the smallest size of nut. ln this type et' Wrench-heed, Jionr sizes of iiutgripping jaws niej; be Iiornied in e single wrench-head having medion lines of each olf the pairs of gripping surfaces parallel Iand set to the cesired angle With respect to the medizin line of the handle.
it is eiiident in `View of the iforegoing, that numerous modifications tney be niede in View of the appended cleinis without departing` troni the spirit of this intention, and no limitation is implied by the drawings which are submitted for illustrative purposes only. 'laying thus described. this invention; i claim: l. n a. nut and bolt-heed Wrench, spaced jews having parallel stepped 'faces v:ind het# ing the corresponding steps of the opposite jaws odset to different entente to occonnnoditte as ine-ny diiierent sizes of nut-s and boltheeds as the number of sets of corresponding steps -plus one.
