My: present invention pertains to ratchet wrenches, and contemplates the provision of a ratchet wrench characterized by the capacity to yieldingly hold and preventdrop- 5 ping or'casual 'displacement of the article;

or articles that are being turned through the medium of the wrench. 1 My novel wrench"s designed more especially" for holding in" detachable manner and 19 turning a washer and nut employed, ina certain special relation, all of which will be hereinafter-fully described; ;T0 the attainmentfof the foregoing my invention consists in the improvement as hereinafter described and definitely claimed In the accompanying drawings forming part of this specification z y M Fig'ure 1 is sideelevation illustrating my novel wrenchand also "illustrating a nut held in the Wrench; f Figurefz is a'view partlyinside elevation and partly in section, showing a Washer in my-novel wrench. v v 1 Figure 3 is a fragmentary longitudinal central section showing bothparts of my improvement. 7 a

Figure 4 is adetail perspective, on can enlarged scale, illustrative of the shoe; comprised in my invention and designed especially for yicldlngly holding a washer.

I v v v i Similar numerals of reference designate corresponding parts in allot the views of the drawings. --t lVitho ut affecting v l of the wrench may be of the construction illustrated or of any other appropriate construction; At 2 the said body "is, equipped witha pawl, under the influence of a flat yieldingly "holding the nut respring 3.; One endportion of the body 1 .is

accommodated for the reception and rotaf=tion of the rotary ratchet member 4 of the "wrench; the said ratchet member 4- provided-- with peripheral'teethfi. My improvements "arecarried by the, said =rotaryrratchet member 4 which in general onalnut designated by 6. In other words the said portion of the member is interiorly of hexagonal form soasto receive the my invention the body 7 is-of annular form. lnteriorly a portion vof the mernber lv s shapeduto receive a hexag- 7; 1925..

nut 6, and so as to assure turning ofthe nut 55 6 when the member 4 is turned.v Another portion of the member 4 is designed to receive and yieldinglv hold" a washer 7,the said deSign'at'ed by 9 the samefigure. For the holding-of the nutg6, the portion 9 of the rotary member at is'provided with a spring strip 10, the saidspring strip 10 having'its :niajor portion ll disposediwithinthe annu- '65 Y lax-part 9 of the member-4 so as to contact with the side of the nut, and alsothaving hooked "portions 11 engaging the edges of t the annular portion 9 as'clearly brought (out ,i t in Figure "The said spring strip 101s alsoclearlfshowniin Figure-3 and; inrFig pures 1 andQ. Tlie portion 8-of theniember V 451s alsoflot general annular form, and for the holding-oi the washer 7, the annulus of 1 theiportion 8 ispartly formed by anarcuate 75 7 shoe 12, movablerelative to the remainder 1 of the'ann'ulus.
