The present invention relates generally to wrenches and more particularly to new and useful improvements in a device or tool of this character which is in the-nature ofa 5 speed wrench and has for its primary object to provide, in a manner as hereinafter'set forth, a wrench embodying a spirally twisted rotatable bar having mounted for reciprocation thereon a inanually operable actuating The invention further includes means for selectively causing rotation of the'bar in either direction when the actuating sleeve is reciprocatedthereon'.
Another important object of the invention 5 is to provide a wrench of the character de rection but wherein the head and the bar will be locked together should said head be rotated in theopposite direction;
Other objects and advantages of the invention are to provide a wrench of the aforementioned character which will be simple in construction, strong, durable, efficient and reliable in use and which may bemanufactured at low cost. V p I I All of the foregoing and still further objects and advantages of the'invention will become apparent from a studyof the following specification, taken in connection with the accompanying drawings -wherein' like characters of reference designate corresponding parts throughout the several views, and wherein: J
Figure 1 is a view in elevation of a wrench constructed in accordance ,with'this invention. Figure 2 is a'detail view in vertical sectio through the actuating sleeve. Figure 3'"is a horizontal cross sectional section; dependently of the head selectively in one diview taken substantially on the line 33 of Figure 2 lookingupwardly,and indicated by the arrows.

, Figure 7 ,sa detail view in elevation showing the'means for lockingthe head to the rov tatable bar. I
. Referring to the drawings in detail, it will be seen that'the reference numeral ldesigna-tes generally an elongated barhaving the oppositely twisted upper and lower spiral portions '2' and 3, respectively, which merge with each other at thelongitudinal center of the'bar '1, as at} 4c, and which terminate at their free ends in the end portions 5 and 6-, respectively of polygonal horizontal QI'OSb A substantially cylindrical sleeve 7 is mountedforreciprocation onthe bar lfand is spaced concentrically with respect thereto,
the sleeve 7 being provided with a longitudinal slot 8* in its up'per'portion, the purpose of which will be more fully hereinafter set forth. Rings 9 andlO are mounted in the end portions of the sleeve 7, bearing balls 11 being interposed between said rings and the sleeve. The inner endsof the rings 9 and 10 have formed thereonthe teeth 12 and formed integrally with the outer end portions of the rings are theinternal flanges 13having aninner periphery of a configuration conforming substantially to the spiral portions 2 and 3 of the bar 1 for operatively connecting the rings 9 and 10 to said .bar 1.
i V Pivotallymountedin-"the' upper and lower portions of the sleeve-'7 "adjacent the rings 9gand 1O is-apair of rockable, double ended pawlsv 14 and 15 whichfas'illustrated to advantageinFigure 6 of thedrawings, are oppositel'ydisposed with respect to'each other. In opposite sides the pawls 1 1 and 15 are provided with notches 16 for the reception of the arcuate spring fingers 17 which are mounted on the upper and lower ends of a bar or rod 18 which is mounted for reciprocation in the sleeve 7. At its upper end the rod 18 is provided with an extension 19 which is operable in the slot 8 and has fixed on its outer end a suitable head or button 20-for engagement by the finger of an operator of the tool for shifting the rod 18 longitudinally in the sleeve 7. The lower portion oftherod-=18 is slidable through a notch in an annular guide 21 which is provided therefor in the lower" portion of the sleeve 7, the guide 21 being fixed in the sleeve 7 and encircling the bar 1.
Referring .now to Figures 4 and 5 of the drawings, it will be seen that a bushing'22 5 of the bar 1 for rotation therewith and said bushing includes a reduced depending portion 23 upon which isirotatably mounted a knurled sleeve 24 having fixed on its upper end portion a flat annulus 25- which is disposed beneath and against the main body portion of the'bushing 22. The reference numeral 26 designates a head provided with a transverse opening through which'is disposed abar 27, said bar 27 being adjustable in the head 26. The head 26 includes an integral depending skirt portion 28 which rotatably encircles the bushing 22 and extends below the main body portion of said bushing 22, 'as clearly seen in Figure 4 of thedrawings. The skirt 28 isprovided with teeth 29 on its inner periphery. The portionof the skirt'28 which extends below the main body portion of the bushing 22 has mounted therein an anti-friction bearing 30 which is cooperable with a substantially conical upper portion of the sleeve 24;.
Referring now to Figurefi of the drawings, it will be seen that theperiphery of the bushing 22 is provided withia notch or-recess 31 the inner wall of which is of a configuration to provide a fulcrum point32. A pawl 33 is operable in the notch or recess 31 and is rockable on the fulcrum point32 for engaging either end of the pawl 33 with the teeth 29 in the skirt 28. The pawl 33 rests on the annulus 25 and is shiftable through themedium of an upstanding finger 34 which is disposed on the annulus 25.
A socket member 35 isrotatably mounted on the anti-friction bearing 36 in the upper portion of the bore of the bushing 22, said socket member 35 extending upwardly into an opening provided therefor in the head26 which communicates with the transverse opening in which the bar 27 is mounted. A spring pressed detent 37 is. mounted in the socket member 35 for engagement'in a recess provided therefor in an intermediate portion of the bar for releasably securingsaid bar 2'( 1n position on the head 26. -T he reference numeral 38 designates the coilspring which furcat-ions l0-thereof a head l1.
is mounted on the polygonal upper portion actuates the detent 37, said coil spring being disposed in the socket member 35 and having one end engaged with the bottom of said socket member and its other end engaged with the detent 37 in a manner to yieldably urge said detent into engagement with the bar 27.
A bifurcated block 39 is fixed on the lower end portion 6 of the bar 1 and has mounted for swinging movement between the arms or he head ll is provided with an apertured ear 42 which isdisposed between the arms or furcations .40 and is pivotally connected thereto by a suitable pin 43 Any suitable means may be provided for detachably fixing the block 39 to the lower end portion 6 of the bar 1.
In use, when the rod 18 is shifted in one direction the-pawlsld and 15 are rocked to engage the teeth 12 on the rings. 9 and 10 in a.
manner to lock said rings. to the sleeve 7 against rotation in opposite directions. In other words, when the ring 10 is locked to the sleeve 7 by the pawl 15, the pawlldwill ride over the teeth 12 on the ring 9 and permit rotation of said ring 9 independently of the sleeve 7. Thus: it will be seen that upon downward movement of the sleeve 7 the ring 10 will be locked thereto and rotary motion will be given to the bar 1 by reason of theoperative engagement of the ring 10 with the portion 3 of said bar 1 The ring 9 being operatively connected to the oppositely spiralled portion-2 of the bar 1 will heretated independently of the sleeve 7. Upon upwardmovement of the sleeve 7 thering 9 willbe locked to thesleeve 7 bythe pawl 1 1 and said ring 9 being operatively engaged with the-spiral portionv 2 of the bar: 1, will rotate said bar 1 in the same direction, the-ring l0 rotating independently of the sleeve 7 duringthe upward movement of said sleeve 7. Should it be-desired to reverse the direction ofrotation of the bar 1, it is only necessary to shift the rod 18 and thus rock the pawls Ll. "i"
and 15 as indicated in broken lines in Figure 6 of the drawings. IllflVlll be noted that the pawls 14:- and- 15 are rocked simultaneously in opposite directions due to the arrangement of the spring fingers 17. During the afore-; mentioned operation the head 26 is rotatable on thebar 1 but should-it be desired to lock the head 26to the bar 1 for-using the bar 27 as a lever forv tightening or loosening a nut, it is only necessary to rotate the ring 2 1 in a manner to shift the pawl 33 to the desired position for engagement with the teeth 29 and in this manner the head 26 is locked to the bar 1 through the medium of the bushing 22. The bar 27-may then'be used to rotate the bar- 1. Ifdesired, the head 11 may be swung to a position substantially at right anglesto the haul and said-bar 1 then used as a lever to tighten or looscn'a nut. The pawls 14 and 15. are, of course, curved longitudinally to conform to the curvature of the sleeve 7 as illustrated to advantage in Figure 3 of the drawings.
It is believed that the many advantages of a wrench in accordance with" this invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction may be had which will fall Within the scope of the invention as claimed.
What is claimed is 1. A wrench comprising an elongated bar including oppositely spiralled portions, nut engaging means on one end of the bar, an elongated sleeve mounted for reciprocation on the bar, means in the sleeve for operatively connecting the bar thereto for rotating said bar in a selective direction upon reciprocation of the sleeve the second named means comprising rings mounted for rotation in the end portions of the sleeve and operatively engaged with the oppositely spiralled portions of the bar, teeth on therings, and oppositely disposed double ended rockable pawls.
