' Application led February 25, 1919. Serial No. 272,054.
To alli/)hom t ma concern:
Be' it known tliat I, SIMON BRALovE, a citizen of the United States, residing at Washington, in the. District of Columbia,
'have invented certain newand useful Im-H provenients in Wrenches, of which .the following is a specification.
This invention relates to wrenches, and more particularly to that class of wrenches which are gear-operated.
The present invention has for its objects, among others, to provide an improved wrench of this lgeneral type, adapted .more especially for use in connection with the nuts upon automobiles or the like, and especially adapted for use in operating o n nuts that are in-out-of-the-way or inaccessibleplaces, hard" to of wrench.
A primary object of the present invention get at with the ordinary form is to provide a wrench lhaving means whereby the end' thereof may be securely held in position so that both hands of the operator will be free for manipulation of the wrench.
To this end the body portion of the wrench.
is extended a considerable distance and the end thereof provided with an ofset, with a stud or pin in said offset, for a purposel which will be hereinafter more fully explained.
Other objects and advantages of the invention will hereinafter appear, and the novel features thereof ywill be specifically defined by the appended claims.
The invention is clearly illustrated in the accompanying drawings, which, with thenumerals of reference marked thereon, forms a-part of this specification, and in which- Figure 1 is a side elevation of a portion of the crank case of an automobile, with portions broken away and parts in section, showing one mode of use of my improved Wrench.
Fig. 2 is a side elevation of the wrench.
Like numerals of reference indicate like parts in the different views.
Referring to the drawings the'wrench is shown as composed of two flat metal plates 1 and 2. These two plates, which may be of a thickness and width in accordance with the strength required, or the uses to which the wrench is'to be put, are disposed parallel with each other and in contact throughout the greater portion of their length, being secured together by suitable means as the riv ets or the like 3 and f1, as shown. The'plate 1 is of less length than the plate 2 and the rivet 4 is placed adjacent the end of the plate 1, as seen in both views.
TheV rivet or other securing means 3 is placed at a distance from the other end of the plate 1 and adjacent said rivet the plate 1 is provided with an offset or band 5k as seen best in Fig. l, to-provide a space between the two plates, and vinthis space arev disposed two 'gears 7 and 8, although more than two may be employed when desired. These gears have their shafts mounted to revolve in the plates 1 rand2, the shaft 9 of the gear 7 being clearly seen in Fig. 2. These gears mesh with each other'as shown, and
the shaft of the gear 7 has a polygonal opening into whichvis received the correspondingly-shaped end of the stem 10 of the handle by means of which the said gear is revolved.
The gear 8 hasits hub provided with an i -opening in which is received the shank 11 of the wrench block, said shank extending through the hub or shaft of the gear 8 and receiving a washer or the like 13 and a cotter against displacement. By turning the handle 15 the gear 7 is rotated and this in turn revolves the gear 8 and consequently the wrench block 12.
The 'end ofthe plate 2 opposite the end to which the gears are applied is extended be- 4yond the plate 1 as seen in Figs. 1 and 2 and just beyond the end of the plate 1 the plate 2 is deflected or provided with a bend 16 so asl to bring the plane of the end of the plate 2 wrench in taking olf or applying the nut 18 within the crank case 19 of an automobile. The end of the wrench carrying the gears is placed through the opening 20, after the lower cover plate of the crank case has kbeen removed, and pushed endwise till the wrench block comes in proper position to engage the nut and then the stud 19 is engaged in the hole 21 from which one of the bolts that secured the said cover plate in position has been removed, and the wrench is thus held against endwise movement without further means. The handle projecting through the opening in the bottom of the crank case serves to give the necessary rotation to the pin or the like 14 by which the shank is held gear 7 and to the gear 8 and in this way the nut is turned one way or the other without dificulty.
The end of the plate 2 hasta firm bearing against the bottom of the Crank case and the offset or bend 1G brings the plates in proper position so as to maintain a parallel horizon` tal position and binding of the gears is prevented. i
Modifications in detail may be resorted to without departing from the spirit of the in-y vention or sacrificing any of its advantages.
What is claimed as new is l. A gear-operated wrench having its gearcarrying members extended `and at one end provided with a projecting member for centering the wrench withfrespect to the nut to be engagedpand for holding the wrench against endwise movement.
2. A gear-operated wrench having its gear-carrying members extended and provided with an offset and means projecting from the end of the body portion for engagement in an opening to center the wrench with respect to the nut to be engaged and to hold the wrench against endwise movement.
3. A gear-operated wrench comprising plates arranged parallel with each other and in Contact with each other for a major portion of their length,` one of said plates being offset adjacent one end, gears disposed in the i gears, the other end of' onel of said plates being provided with a stud for engagement 1n an opening to prevent endwise movement of the. wrench.
I. A gear-operated wrench composed of plates secured together with the plates in contact with each other for a major portion of their length, said plates provided at one end with intermeshing gears disposed in the space between said plates, and the other end of one of said plates being provided with a laterally-projecting stud. l
5. A gear-operated wrench composed of plates iforming the body portion of the wrench, one of said plates being offset at one end and the other plate offset in the opposite direction at the other end. of the body portion, Coperating gears in the space between the plates at one end, and a stud projecting from the end of one of the plates at theother end of the body portion. .v
In testimony whereof I affix my signature in the presence of two witnesses. s
