Specification of Letters gate, pat t dily y '17 1921:
Application filed August 20, 1919.1:Seria1 No. 318,718
To all whom it may concern:
Be it known that I, CLIFFORD Foonn, citizen of the United States, residlng at Cobden, in the county of Union and State of 1 Illinois, have invented certain new and useful Improvements 1n Wrenches, of whlch the following is a specification, reference being had therein to the accompanying drawing. 7
This invention relates to new and usefnl improvements in wrenches, and especially 1n the provision of a wrench so arranged that a tool held in the socket thereof may be op erated around the corners, or in such places where an ordinary wrench is inaccessible.
The invention comprises a simple and efiicient device of this nature, having various details of construction, combination and arrangement of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claim.
My invention is illustrated 1n the accom-.
panying drawings which, with the letters of reference marked thereon, form a part of this application, and in which:
Figure 1 is a side elevation showing the application of my invention.
Fig. 2 is an end view.
Fig. 3 is a sectional view through a sprocket chain and gear connections between the bitstock and socket stock.
Fig. dis an edge view of Fig. 3, and
Figs. 5 and 6 are detail viewsof the casing in which the sprocket chain and gear connections are mounted.
Reference now being had to the details of i the drawings by letter:
A designates a bitstock having a crank handle B, and C is a breast plate swiveled to one end, these features being common to the ordinary stock. One end of the bitstock is squared, as at D and'its end is provided with a threaded aperture adapted to receive a screw F passing through a clamping plate H. Fitted over the end of the bitstock is a casing, details of which are shown in Figs. 5 and 6 of the drawings, and which is made up of two parts, the casing proper being: designated by letter I, and the covering by letter J. Said casing has integral lugs I projecting therefrom along its marginal edge, and which are adapted to engage similar shaped recesses formed in the marginal edge of the cover, and afiording means whereby the cover may be held from lateral movement when adjusted in place. The cover and casing are provided with registermg apertures N through which a screw 0 is adapted to pass, the apertures in the cover being threaded to engage the threads of the screw to hold the parts securely together.
Journaled in registering apertures in the casing and cover is a hub Q of a sprocket wheel Q. Said hub has a square outlined opening Q therein adapted to fit over the squared portion D of the bitstock. When the hub is adjusted in the casing and the casing placed over the bitstock, the plate H 18 held clamped against the face of the cover by means of the screw F, as shown clearly in the drawings.
A wrench socket P is journaled in other 7 registering apertures in the casing and cover, and the wrench socket has an integral Fig. 1 of the drawings, it will be noted that by turning the bitstock, the wrench socket is adapted to engage the nut, or other object, and may be rotated in such position as would be inaccessible by the use of an ordinary wrench, and by reason of the gears being of different sizes, the rotary movement imparted to the bitstock maybe accelerated. It will be noted that the sprocket wheel upon the bitstock is of less diameter than the sprocket wheel upon the part engaging the bit, or nut to be turned. The difference in leverage between the two wheels enables the application of increased torque to the part to be turned over than possible if the casing and cover having registering openings therein, a bit socket journaled in said openings and having an annular shoulder adapted to bear against a flange about one of said openings, a plate fastened to one end ofsaid socket and bearing against the face of the casing, a sprocket wheel rotatin with said socket, a bitstock having an en journaled in openin 's in the casing and cover, a sprocket w eel rotating with the portion of the bitstock within the casing, and a sprocket chain passing about said wheels, the diameter of the driven sprocket being greater than that of the driving sprocket for 10 the purpose of obtaining increased torque.
In testimony whereof I hereunto afiix my signature in presence of two witnesses.
