GILBERT H. SPECKMAN, OF AURORA, INDIANA.

WRENCH.

My present invention pertains to wrenches, and has for its object the provision of a peculiar and advantageous wrench for holding and turning nuts and washers incident to the installation of transmission bands in Ford automobiles.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawing, forming part of this speciiicationz- Figurel is an elevation, partly broken away, illustrating the preferred embodiment of my'invention.

Figure 2 is an elevationA of the wrench taken at right angles to Figure 1.

Figure is an enlarged detail longitudinal section illustrating the portions of my novel wrench provided for the reception and retention of'a nut and washer complementary to the nut.

Similar numerals of reference designate corresponding parts in all of the views of the drawing. .f

Among other elements, my novel wrench comprises a handle portion 1 characterized by a` longitudinal slot 2 and also characterized by an intermediate offset portion 3 in which is a longitudinally disposed aperture et. At one end, the handle portion 1 is preferably, though not necessarily, provided with a circular enlargement 5 formed by parallel portions in which are transverse circular apertures and journaled in the said circular apertures of the portions 5 are the trunnion portions of an annulus 6 which is provided with an opening 7 of angular form and is also provided with peripheral teeth 8, the latter for cooperation with a spring pressed pawl 9 mounted in the handle.

As will be readily appreciated, the equipment described permits of the handle portion 1 being used after the manner of a ratchet wrench.

The handle portion 1 is provided at its opposite end, with reference to the ratchet mechanism described, with an annular portion 10 having an inwardly directed flange 11.

Mounted to turn about its axis in the annular portion 10 is the nut holding and turning member 12 of my improvement. The said member 12 is provided with a flange 13 opposed to the iiange 11 of the annulus 10, and is also provided with an interior 14 Application led February 16, 1927. lSerial No. 168,635.

shaped to receive a nut designated by 15, and is further provided with an interior rabbet 16 designed to receive the washer 17 complementary to the said nut 15. Exteriorly, the member 12 is knurled as designated by 18 to facilitate its turning by the thumb and finger of the operative, and it will be noticed that the knurled portion 18 extends laterally relative to the plane of the handle portion 1 so that the member 12 may be actuated with facility. 1t will also be noted by comparison of Figures 2 and 3 that the member 12 is provided withv a circumferential flange 19, and that a split ring 2O is interposed between said flange 11 of the annulus 10, the split ring serving to hold the annulus 12 in proper working relation to the annulus 10 and this without'interfering -in any measure with the turning of the annulus or member 12 about its axis in the annulus 10. It will be also appreciated that the split ring 2O lends itself to ready assembly of the parts.

1n addition to the elements referred to, my novel wrench comprises a longitudinally adjustable washer and'nut retainer 21, the element being so designated because of its adaptability of the position shown in Figures 1, 2 and 3, to retain a washer and nut in the member 12 and this in such manner that there is no interference with the turning of the member 12 and the nut and washer about a common axis. The retaining member 21 is provided with an enlarged bifurcated end portion 22, and it is also provided a.

with a shank, the said shank being guided and movable rectilinearly in the aperture 4 in the handle portion 1, and being provided with a rear hooked shaped portion 22, the bight of which portion 1. It will be noticed by reference to Figure 2 that the handle portion 1 is provided in one side with an indenture or depression 23, and that. the bill of the hook 22 is provided wit-h a projection 23x designed to be sprung into and out of the depression 23. It will be apparent from the foregoin that when the retaining element 21 is moved to the position shown to retain a washer and nut in the member 12, the springing of the proj eotion 23X into the depression 23 will serve to hold the retainer 21 against casual movement. vWhen however a little stress is applied to the end of the hook bill, the

flange 19 and the f is disposed and movable in Q the before mentioned slot 2 of the handle Y member 21 may be easily retracted yso as to release the Washer and nut and leave Vthe member 12 'free to be disengaged from the said Washer and nut.

In the use of my novel Wrench for the in'- stallation of' neW bands in Ford automobiles,

the Washer and nut are placed Within the turnable member 12, and the retainery 21 is moved Vto the position illustrated, Whereupon casualclisplacement of the VWasher and 'nut from the member 12 Will be precluded.

IVith the Washer and nut disposed as stated, my novel Wrench is used merely to start a nut on a shaft, and after the 'nut With the Washer bei-ore it yis vstarted on the shaft, the retainer 21fis retracted, the member 12 is disengaged from the Washer and nut, and then theratchet portion of my novel Wrench is used to tighten the nut. A

Notwithstanding the practical advantages of-my novel Wrench, -it will be appreciated from the foregoing that the Wrench is simple and inexpensive in construction, is susceptible of being readily manipulated, and'in general is VWell adapted to withstand the usage to which Wrenches of corresponding types are ordinarily subjected. l 'n I have explicitly described the construction and relative arrangement of the parts `embraced in the present and preferred embodiment of my invention in order to 'impart a full, clear, and exact understanding of the said embodiment.

' I do not desire, however, to lbe understood as limiting myself to the precise structure disclosed, my invent-ion being defined by my appended claim Within theV scope of which modifications may be made Without departure from my invention.

Having thus described the invention, what I claim is In a Wrench and in combination, a handle portion having a longitudinal slot, and a depression in one ,sideV adjacent to said slot and also having at an intermediate point a lateral offset and -a longitudinal aperture therein, and i'urt-lier having an-annulus with an Vinwardly directed iiange, a "turnable nut receiving member having a flange disposed Withjin the annulus ,of the Vhandle portion and opposed to the flange of said all-.Ilulus and also having a Toughened lportion disposed laterally lto the plane of the handle portion and a 'circumferential lflange Vspaced from Athe flange ,of the annulus, a split ring surrounding the turnable member and i11- terposed between :therfiange thereof andthe flange on the Yannulus,-.and .a longitudinally movable nut retainer having a biu-reated .portion movable into and out of coincidence with the turnable member, and Kalsol hav'- 'ing a shank ydisposed and movable inthe aperture in. the offset of the handle portion and :further having at its rear end a hook, the bight of which is disposed in the slot of the handle portion and the bill of which is provided With a projection adaptedto be sprung into and out of the depression Ain the handle portion,
