Description
April 29, 1952 c. D. MARSHALL GEAR-OPERATED WRENCH CONSTRUCTION Filed May 10, 1949 C'. D.MarskaZZ INVENTOR ATTORNEYS.
Patented Apr. 29, 1952 UNITED STATES PATENT OFFICE GEAR-OPERATED WRENCH CONSTRUCTION This invention relates to wrench construction, the primary object of the invention being to provide a wrench of the: socket type which may be used in positioning or: removing nuts in restricted areas where it is impossible to operate a wrench in the usual manner.
An important object of the invention is to provide a wrench of v this character including a hollow head in which "a bearing block is held, the bearing block having bearing openings for the reception of the main socket shaft, and the main operating shaft of the Wrench, the bearing block being held in place by a cover plate which closes one side of the head. j
With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from'the spirit of the invention as claimed.
Referring to the drawing Figure 1 is a bottom plan view of a wrench constructed in accordance with the invention.
Fig. 2 isa sectional view taken on line 22 of Fig. 1.
Fig. 3 is a sectional view taken on line 3-3 of Fig. 2.
Referring to the drawing in detail, the reference character 5 indicates the hollow handle of the wrench which is provided with a hollow head 6 which has an open side normally closed by means of the closure plate I which is held in place by means of the screws 8.
Mounted within the hollow head of the wrench, is the bearing block 9 which is formed with a substantially large bearing opening in" one side in which the main socket wrench shaft l fits for rotation therein, the outer end of the shaft in being squared so that the usual removable sockets used in removable socket wrenches, may be positioned over the extended end of the shaft l0.
Secured to the shaft I0. is the beveled pinion II that meshes with the small beveled pinion H! which is secured to the inner end of the power shaft 13 of the wrench, the power shaft l3 being extended through the hollow handle, as clearly shown by Fig. 2 of the drawing.
The inner end of the shaft I3 is reduced and extended into a bearing opening in one side of the block 9, where the shaft rotates.
The shaft l3 also operates over the roller bearings 14 that are held within recesses formed in the inner surface of the hollow handle 5, there beingprovided a socket l formed on one end of the shaft It, for the reception of the usual socket mat of a wrench.
1 Claim. (Cl. 81-57) In using the wrench in restricted places, the head end of the wrench is positioned with the socket shaft l0 supporting the socket for positioning over the nut under operation.
The usual ratchet wrench having a socket shaft, is used. with the socket shaft inserted in the socket l5.
As the usual ratchet wrench is rotated, it will be obvious that the shaft I3 will be rotated to operate the gear H and main socket shaft 10, rotating the socket head positioned thereon, to tighten or loosen the nut under operation.
Should it be desired to remove the gearing to replace or repair elements of the wrench, it is only necessary to remove the plate 1 and withdraw the shaft l3. The block may now be withdrawn from the hollow head of the wrench and the beveled pinions or their shafts lubricated or repaired.
Having thus described the invention, what is claimed is:
A wrench comprising a hollow handle, a hollow head formed integral with the handle at one end thereof, a removable bearing block mounted within the hollow head in contact with the wall thereof, said bearing block having an opening in one side surface thereof, a main socket shaft resting within the opening and extending beyond the surface of the housing wall through which the shaft extends, and on which a socket member is removably positioned, a beveled gear in the head mounted on the inner end of the socket shaft for rotation therewith, said beveled gear occupying the space between the block and adjacent surface of the hollow head, a power shaft extending through the handle, said power shaft having a reduced inner end fitted in a bearing opening formed in one end of the bearing block, a pinion on the reduced end of the power shaft cooperating with the beveled gear of the shaft and rotating the main socket shaft and pinion, and a cover plate closing the side of the hollow head, said cover plate contacting with the block providing a bearing support for the block securing the bearing block within the hollow head.
