Y- Application August 5, 1947, Serial No. 266,325.

lll,

ticularly related to the socket type wrench.

The primary object of the invention is to provide a wrench that can be operated by a power drill reaching in to locations that would not be accessible to the conventional socket wrench construction.

A further object of the invention is to provide a means Within the wrench for allowing the power drill to overrun when a predetermined amount of resistance is offered to the turning of the nut on the bolt.

A still further object of the wrench is to provide means within the Wrench for reversing the rotation of the nut on the bolt by simply shifting the wrench relative to the nut selecting a reverse socket.

These and other incidental objects will be apparent in the drawings, specification and claims.

Referring to the drawings:

Figure 1 is a fragmentary side view of my new `and improved wrench applied to a nut located in an inaccessible location and also illustrating a fragmentary view of the power drill applied thereto.

Figure 2 is a plan view of the wrench partially broken away for convenience of illustration.

Figure 3 is an enlarged fragmentarysectional view taken on line 3-3 of Figure 2 illustrating the over running feature incorporated in the wrench.

Figure 4 is an enlarged fragmentary side sectional view taken on line 4-4 of Figure 2.

Figure 5 is a perspective View of the driving element incorporated in the over running assembly.

Figure 6 is a perspective view of an oppositely disposed element from that of Figure 5.

Figure 7 is a perspective view of the gear associated with the over running driving elements.

Figure 8 is a perspective viewV of one of the friction disks associated with the over running element.

In the drawings:

My new and improved wrench is indicated generally by numeral I. A train of gears 2, 3, 4, 5, I5 and I are journalled Within 'the housing 8 of the wrench. The driving gear 2 is journalled to the driving shaft y9 and is free to revolve thereon. The driving Shaft 9 has a disk I0 forming part thereof. The disk and shaft having a hub II journalled within the bearing I2 of the casing. The driving shaft y9 extends into the .i t .1.151. Law'. I2 Y gear 2 has a solid web I5 extending between its rim and teeth or hub and its central point.

Located on either side of this web are friction Washers I6. A wing bolt I1 is threaded within the end I8 of the driving shaft 9 and when this bolt is tightened it clamps the disk I0 and the floating disk I4 together compressing the friction Washers IE against the disk I5 of the gear 2, thereby rotating the said gear. The wing nut I'I bearing against the hub I3 of the disk I4.

The power drill I9 drives the socket 2), which is applied to the extension 2l of the driving shaft 9. When the gear 2 is driven by the above described assembly it willdrive the gears 3, 4, 5, 6 and 1. The gears 6 and 1 have sockets 22formedtherein. These gears are journalled Within the housing 8 by their hubs 23 and 24. Removable adapter sockets 25 are dropped into the sockets 22 of the gears and come in different sizes to fit various size bolts and nuts. The gear 'I will revolve a nut in the opposite direction to that of the gear 6 and is located as illustrated in Figure 2 so that either of the sockets may be applied to the nut.

I will now describe the operation of my new and improved wrench. Referring to Figure l, the nut 26 is located under the overhang 21 having an obstruction 28 located thereon. My new and improved wrench can be inserted into the space 29 and applied to the nut permitting the drill I9 and its driver socket 29 to operate.

When the nut has been seated it is desirable to permit the drill I9 to over run without harm. This is accomplished by driving the train of gears through the friction washers IS disposed between the web I5 of the gear 2 and the disks Ill and I4 secured to the driving shaft 9. The amount of slippage of over run will depend on how tight,

the wing bolt Il is tightened. This is one of the outstanding features of my wrench construction and makes its operation possible.

I do not wish to be limited to the exact mechanical structure as shown, as other mechanical equivalents may be substituted still coming within the scope of my claims.

What is claimed as new, is:

1. A socket Wrench including a housing forked at one end, a drive shaft having a disk, a hub, and a flange, the end of the hub being square and formed with a threaded opening, a bearing formed in one side of the housing to receive the flange, a gear wheel rotatably mounted on the hub of the shaft, a friction disk between the flange and the surface of the gear Wheel, a sec- 'ond friction disk having -a hub mounted on the hub I3 of the disk I4 and revolves said disk. The 55 square end of the shaft, the said second-mentioned friction disk engaging the surface of the removably mounted gear Wheel, a bearing in the housing in alignment with the shaft to receive the hub of the second-mentioned friction disk, a headed, threaded screw, the screw engaging the threaded opening in the shaft and the head engaging the hub of the second-mentioned friction disk, a gear mounted in each fork member of the housing, said gears intermeshing and provided with sockets, and a train of gears between the rotatably mounted gear on the shaft and one of the gears in the fork of the housing.

2. A socket Wrench including a housing, one end of which is forked, the sides of the legs of the fork having bearings, a gear wheel supported on a shaft in each leg of the forked end of the housing, said gears intermeshing and provided With sockets, a train of gears in the housing, one end gear of the train of gears meshing with one of the gears in the legs of the fork, the opposite end gear of the train of gears rotatably mounted on a driving shaft, a driving shaft mounted in the housing, and friction means associated with the driving shaft to permit slipping of the rotatable gear under undue strain on the gears in the legs of the fork.
