SOCKET WRENCH Filed March 15, 1962 I N VEN TORS' ATTD RN EYE United States Patent O 3,126,774 SOCKET WRENCH Cleatues A. Carr, 1502i Harris, and Eldon- L. Mardoek, 1814 A St., both of Eureka, Calif. Filed Mar. 13, 1962, Ser. No. 179,355 3 Claims. (Cl. 81-125) The present invention relates to tools generally and in particular to a socket Wrench ot the screwdriver type.
An object of the present invention is to provide a useful tool adapted to Istant bolts and the like in hard to reach places, one which has means for retaining a bolt in the tool until the bolt is stamted in its position a bolt hole, and one which is highly elective in action.
Another object of the present invention is to provide a hand tool of the screwdriver type which may be employed with long or short bolts, one which serves to free the hand of the user in starting bolts or the like, and one which can be manufactured in quantity at reasonable cost.
A further object of the present invention is to provide a screwdriver type magnetic tool having replaceable sockets so as to accommodate bolt heads of various sizes, the magnetic portion ot the tool being operable with any size socket desired.
These and other objects and advantages of the present invention will be fully 'apparent upon consideration of the following description of the tool of the present invention, the description 4to be considered in the light of the drawing attached, in which:
FIGURE l is a cross-sectional vie-w of the tool of the present invention,
FIGURE 2 is a view partially in section showing the tool in use,
FIGURE 3 is a view taken on the line 3 3 ouf FIG- URE 1,
FIGURE 4 is la view .of the portion of the tool showing how a bolt is held in a straight position,
FIGURE 5 is a sectional view of a modified form of the socket portion of the tool,
FIG-URE 6 is la view taken on the line 6-6 of FIG- URE 5, and
FIGURE 7 is a view similar to FIGURE 5 showing a larger socket in use on the tool of the present invention.
yReferring in detail to the drawing, the socket wrench of the present invention comprises an elongated hollow body 10 preferably fabricated of ya non-magnetic material. In the form of the invention shown in FIGURES l to 4, inclusive, the body 10 has one end llared out to form a socket constituting means on one end of the body 10 adapted to engage the head of a bolt, the flared out end portion being designated by the reference numeral 12 and the bolt being designated by the numeral 14.
A handle 16 is carried on the other end of the body 1l) and preferably is fabricated of plastic material or the like.
One end of the handle is formed with a bore 18 of a size to receive therein the adjacent end portion oi the body 10 and the other end of the handle i16- is provided with a threaded bore 2li having a diameter less than the diameter ot' the bore 18. The bores 18 and I20 are disposed in longitudinal alignment with the inter-lor of the body 10 and iare connected in communication therewith.
A rod 22 has a threaded portion 24 adjacent one end threadably engaged in the bore 2i) of Ithe handle 16. A knurled wheel 26 is mounted upon the free end of the rod 212 adjacent the -threaded portion 24 and provides a means for gripping the rod 22 order to rotate it within the handle l16 to advance or retract the rod 22 with respect to the body 10.
The other end of the rod 22 remote from the knurled 3,126,774 Patented Mar. 31, 1964 ICC wheel 26 carries a magnet 28 of a diameter to slidably lit within the bore Slt ot the body 10.
In the form of the invention shown in FIGURES 5 to 7, inclusive, the body 1d is provided on its lower end with an outwardly bent lug element 32 received in a recess 34 provided in the stem portion 36 of a removable socket 38.
In FIGURE 7, a socket 38 is shown of a greater diameter than the socket 38 shown in FIGURES 5 `and 6. The stern 36 of the socket 38 lits on the end of the body 10 as in FIGURES 5 and 6r.
In use, the magnet 28 is insertable into and withdrawyable from the sockets 12, 38, 38 by turning the rod 22 within the handle 16. This permits the tool lof the present invention to position la fastening element such as the bolt 14 in position adjacent the hole to receive it and to start the bolt 14 with ease and facility.
In FIGURE 4 it will be seen that the bolt 1&4 might be ata cocked angle previous to seating on the magnet `28 but that the magnet |28 will hold the bolt in ya straight position as in FIGUR-ES l and 2, after the magnet has contacted the head of the bolt.
The tool of the present invention makes it possible for bolts of all lengths and sizes to be started in inaccessible places whene the lingers may not be able to hold the bolt and it also frees the hand of the user which normally would have to hold .the bolt while a wrench was applied.
Sockets of Yall sizes may be provided tor use with the tool and it is expected that numerous changes and modications may be made the invention as will be found practical Without departing from the spirit of the invention as set forth in the appended claims.
