T. J. coLxHAN v ff WRENCH 5 Filed March 13, 192;
Patented Feb.. 5, i924..
.statins Wannen.
Application filed March 13, 1923. Serial o'. 624,706.
To all whom t may concern.'
Bc it known that l, THOMAS J. COLIHAN, of Girardville, in the county of Schuylkill and State of Pennsylvania, a citizen of the United States, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.
My invention relates to wrenches and has for its object the provision of a strong simple and durable tool by the use ot which a nut may be quickly and easily turned home.
The invention is illustrated in the accompanying drawing and will be hereinafter fully set forth and specifically delined.
In the drawing, Fig. 1 is a side elevation of a wrench embodying my invention.
Fig. 2 is a longitudinal section,
Fig, 3 is a transverse section on the line 3-3 of Fig. 2,
Fig. 4 is a bottom plan view of the nutengaging socket,
Fig. 5 is a side view of the socket.
ln carrying out my invention, I employ a rotatable stock 1 which is constructed with a ratchet 2 at one end and at its opposite 'end has a reduced threaded terminal 3. Immediately adjacent the threaded terminal 3, the stock presents a smooth circular bearing portion 4 of slightly greater diameter than the threaded terminal while at the inner end of said bearing portion is a short length 5 having an angular cross section. Rotatably mounted upon the stock at the ends of the ratchet 2 is a crank or lever handle 6 carrying a pawl 7 which will ride freely over the ratchet when the handle is swung or rocked in one direction but will engage the ratchet when the handle is rocked in the opposite direction so that the motion of the handle will be transmitted to the stock. A sleeve 8 fitted upon the stock adjacent the handle enables the user to support the stock while permitting rotation of the same and a stop collar 9 is secured on the stock adjacent the end of the bearing sleeve 8 to prevent displacement of the sleeve longitudinally oi the stock.
Upon the angular length or section 5 of the stock is fitted a bevel gear 10 and upon the bearing portion 4 is tted a short sleeve 11 and a beveled gear 12 arranged in opposition to the similar gear 10. A nut 13 is mounted on the threaded terminal 3 and bears against the end of the hub 14 of the gear 12 to retain the gear on the stock, said gear being rotatable on'the bearing portion 8 of the stock. A washer 15 is fitted on the portion 8 of the stock between the face of the gear 12 and the adjacent end of the sleeve 1l and a similar washer 16 is disposed between the face of the gear 10 and the adjacent end of the said sleeve. On the under side of the sleeve 11 is a stud or post 17 upon which is rotatably mounted a beveled gear 18 which meshes with both gears l0 and 12, a washer 19 being fitted about the stud between the upper side of the gear 18 and the bottom of the sleeve 11,' and a washer 2O being fitted on the stud against the under side of the gear and a nut 21 which is threaded onto the lower end of the stud to retain the gear thereon.
On the under side of the gear 18 is a rim or collar 22 which surrounds the washer and nut 21 and is adapted to t within the hollow head 23 of the nutengaging socket 24, a cotter pin 25 or a similar device being inserted through openings provided therefor in the head 23 and the rim 22 to secure the socket to the gear, as shown, and as will be readily understood.
It is thought the operation will be readily understood. The nut to be turned home is engaged by the socket 24 and the operator grasps the sleeve 8 in one hand and then rocks the handle 6 with the other hand so that the stock will be rotated. The rotation of the stock is imparted directly to the gear 10 which at once actuates the ear 18. The gear 18 rotates about the stu 17 and the socket 24, of course, rotates with said gear as it is secured thereto through the head 23 and the rim 22. Consequently` the nut on which the socket is engaged will be quickly turned home, and it will be une derstood, of course, that the sockets are provided in various sizes and used interchangeably so that a nut of any size may be turned by the wrench. The gear 12 is an idler driven by the gear 18 and serves as a govyernor to prevent spasmodic movement of the same so that said gear 18 will not tend to bend the stud 17 but will always be in true concentric relation thereto and the torsional strain upon the stud and the stock will be distributed and distortion of said parts prevented. The washers 15, 16 and 19 serve to maintain the several parts in operative relation and minimize the wear upon the faces of the gears and the surfaces opposed thereto.
Having thus fully described my invention7 what I claim as new and desire to seits under side spaced away from said stud 10 cure by Letters Patent of the United States rotatably mounted on the stud and meshing iszwith the opposed gears7 and a work-engag- A wrench comprising a rotatable stock, ing socket having a hollow head fitting 5 a sleeve fitted loosely on the stock, opposed around and detachably secured to said rim.
