Abstract
ADJUSTABLE EXTENSION FOR SOCKET WRENCHES OR THE LIKE
ABSTRACT OF THE DISCLOSURE
Extensions to socket wrench sets or ratchet wrench sets are provided in one or two predetermined lengths which are not always the most convenient length of the operation being performed. This device provides a hollow handle en-gaging portion with internal splines and a splined exten-sion shaft slidable therein and having a tapered clamping sleeve surrounding the extension and screw threadably en-gaging the end of the handle into which the splined exten-sion slides. A standard socket engaging end is provided on the other end of the extension. When the clamping sleeve is loosened, the extension can be moved endwise relative to the handle and when the desired overall length is obtain-ed, the sleeve is tightened thus clamping the two parts to-gether against endwise movement with the splines preventing rotation of one part relative to the other.

ADJUSTABLE EXTENSION FOR SOCKET WRENCHES OR THE LIKE
BACKGROUND OF THE INVENTION
This invention relates to new and useful improve-ments in extensions for wrench sets and the like.
Conventionally, a socket wrench set is provided with a plurality of nut and bolt engaging sockets having a squared recess in one end engageable with a corresponding squared end on a standard handle, pivoted type handle or a ratchet handle which normally extends at right angles from the longitudinal axis oE the socket when the socket is engaged upon the handle.
Also provided in the majority of such socket or ratchet sets is one or more extension rods which enables the handle to be spaced from the socket so that the socket can be utilized in locations where adjacent components may pre-vent rotation or partial rotation of the handle.
However, such extensions are often inconvenient for the circumstances within which the socket set is being used. For example, when being used on an automobile engine, it is often desirable to be able to preselect the length of the extension so that the handle can be positioned in the mos-t convenient location for efficient operation~ but with only one or at the most, two fixed extensions being supplied, ,~
.t ~ ~ 7 this is often impossible.
SUMMAKY OF THE INV~NTION
The present invention overcomes these disadvantages by providing firstly, an extension for socket wrenches which is adjustable within limits of the components thereby enabling the most convenient length to be determined between the socket and the offstanding handle. Secondly, the same principle can be incorporated in the handle portion, either standard ratchet or pivoted, so that the effective length thereof can be ad-justed.
In accordance with the invention there is provided an adjustable extension assembly for socket wrenches and the like comprising in combination a hollow engaging portion and an extension shaft portion slidably engageable therein for lengthwise movernent relative thereto, means on the distal end of the extension shaft portion operatively engageable with an associated socket or the like, means to prevent rotation of said extension shaft portion relative to said hollow engaging portion and means to detachably clamp said extension shaft portion to the said hollow engaging portion against relative lengthwise movement one with the other, said means to detachably clamp said extension shaft portion to said hollow engaging portion including a resilient, slightly tapered, truncanted cone-shaped end formed on the end of said hollow engaging por-tion engaged by said extension shaft portion, at least one 1~
7~i longitudina:Lly extending slot formed through the wall of said truncanted cone-shaped end extending from the distal end there-of inwardly therefrom, said truncated cone-shaped end being screw threaded and an internally screw threaded, tapered, lock-ing sleeve slidably over said extension portion and screw threadably engaging said truncated cone-shaped end, the tighten-ing of said locking sleeve on said truncated cone-shaped end compressing sai.d end around said extension portion and clamp-ing same against endwise movement relative to said hollow engaging portion.

With the foregoing in view, and other advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, the invention is herein described by reference to the accompany-ing drawings forming a part hereo~, which includes a descrip-tion of the preferred typical embodiment of the principles of the present invention, in which:
DESCRIPTION OF THE DRAWINGS
.. . .
Figure 1 is a side elevation of the extension handle assembly.
Figure 2 is a fragmentary longitudinally cross sectioned exploded view of the three components Eorming the assembly.
Figure 3 is a cross sectional view along the line 3-3 of Figure 2.
Figure 4 is an end view along the line 4-4 of Figure 2.
Figure 5 is an end view along the line 5-5 of Figure 2.
Figure 6 is an end view along the line 6-6 of Figure 1.
Figure 7 is an end view along the line 7-7 of Figure 1.
In the drawings like characters of reference indi-cate corresponding parts in the different figures.
Proceeding therefore to describe the invention indetail and describing first, the structure shown in Figures 1 - 7, the device consists of three parts, namely an extension shaEt portion collectively designated 10, a handle engaging portion collectively designated 11 (defined as a hollow engag-ing portion) and a clamping or locking sleeve collectively designated 12.
In detail, the extension shaft portion is prefer-ably formed from solid material such as steel or the like and is preferably substantially circular in cross section, formed with at least one and preferably a plurality of spaced and parallel, longitudinall.y extending splines 13 on the outer surface thereof.
The distal end is provided with a flange 14 from which extends a socket engaging portion 15 which is usually square in cross section. This portion engages within the square recess formed on a standard socket (not illustrated) with the socket being detachably held in position by means of a spring loaded ball 16 on one face 17 of the portion 15 with the ball being compressible into the surface as the socket is engaged thereover.
The handle engaging portion is a hollow cylindri-cal portion having a plurality of spline receivi~g grooves `
18 formed around the inner wall thereof, the number of grooves preferably equalling the number of splines 13.
These grooves extend longitudinally from one end to the other but terminate spaced from the end speci~ical-ly designated 19. ~his end 19 is preferably formed with a square cross sectioned recess adapted to be snap engaged by a conventional socket wrench handle (not illustrated) which extends at right angles from the longitudinal axis of the extension assembly when positioned on the ha.ndle engaging portion 11.
It will therefore be appreciated that the shaft extension portion 13 may slidably engage the handle engag-ing portion 11 so that the overall length of the two por-tions may be adjusted within the range of the length of the two components or portions.
The end of the handle engaging portion 11, speci-fically designated 20, is slightly tapered on the exterior surface thereof and this slightly tapered, truncated cone-shaped end 20 is screw threaded externally as clearly shown in Figure 2.
A truncated conical sleeve 21 is .internally screw threaded as at 22 and slides freely over the extension shaft portion 10 with the screw threads 22 engaging the screw threaded end 20 of the handle engaging portion. This handle engaging portion is provided with at least one and prefer-ably a plurality of spaced and parallel slots 23 formed ~7~76 through the wall thereof and extending from the extremity 24 towards the inner end of the conical shaped end 20 so that when the sleeve 12 is tightened upon the end 20/ the resiliency of the material forming the conical end 20 per-mits the sleeve to compress the end 20 and clamp same around the extension shaft portion 13 thus holding it ag-ainst endwise movement relative to the handle portion but at the same time it will be appreciated that the splines 13 engaging the grooves 18, prevent relative rotational movement between the two portions.
While a splined construction is shown in the draw-ings, nevertheless it will be appreciated that other means may be provided which permit relative lengthwise movement of the two portions yet prevent relative rotation thereof.
For example, the portion 13 could be formed with a square or other non-circular cross sectional configuration with a corresponding shape forming the inner bore of the handle en- ;
gaging portion 11 and the invention is of course not limited to the splines illustrated and described.
In use, the desired size socket is engaged upon the end 15 and the desired handle engaged within the end 19.
The length of the extension handle assembly is adjusted to suit the circumstances whereupon the sleeve 12 is tightened thus clamping the two parts together.
7~6 SUPPLEMENTARY DISC~OSURE
-Figure 8 is an elevational view showing the inven-tion incorporated within a ratchet handle assembly.
Figure 9 is an elevational view showing the inven-tion incorporated within a pivoted handle assembly.
Figures 8 and 9 show further uses for the invention.
Figure 8, for example, shows the splined shaft or extension portion collectively designated lO slidably engage-able within the hollow engaging portion which in Figures 8 and 9, is collectively designated 25. In Figures 8 and 9, this hollow extension portion forms the cylindrical handle o~ a wrench handle assembly and the portion lO is slidably engageable lengthwise within the hollow handle and is clamped in the desired location relative to the handle, by means of sleeve 12 in a manner similar to that described for the previous embodiment, it being understood that the interior surface of the handle 25 is splined to receive the splines 13 and that the sleeve 21, operates to clamp the extension portion 10 in the desired position in a similar manner.
A conventional ratchet assembly or component col-lectively designated 26 is provided on the distal end of the spline extension portion 10 with a square cross sectioned socket engaging portion lS extending from one side of the generally circular ratchet component 26, it being understood that this ratchet component is conventional so that details thereof are not believed necessary. A spring loaded ball 16 extends from one face of the portion 15 and is compressible against a spring in a conventional manner.
Figure 9 is similar with the exception that a U-shaped yoke 27 is secured to the distal end of the extension shaft portion 10 with the leg 28 thereof lying longitudinally with respect to the portion 10. The square cross sectioned socket engaging portion 15 is secured to an extension 29 which in turn is pivoted between the legs 28 of the yoke 27 by means of a pivot pin 30. This construction may take the form of a universal nut before the portion 15~ if desired.
This permits the effective length of the handle assembly to be varied so that it may be used in confined spaces if desired. It also controls the leverage which may be applied to the socket engaged therewith, assisting in avoid- , ing over-torquing of nuts and bolts engaged by the socket.
Since various modification can be made in my inven-tion as hereinabove described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.

Proceeding therefore to describe the invention indetail and describing first, the structure shown in Figures 1 - 7, the device consists of three parts, namely an extension shaEt portion collectively designated 10, a handle engaging portion collectively designated 11 (defined as a hollow engag-ing portion) and a clamping or locking sleeve collectively designated 12.
In detail, the extension shaft portion is prefer-ably formed from solid material such as steel or the like and is preferably substantially circular in cross section, formed with at least one and preferably a plurality of spaced and parallel, longitudinall.y extending splines 13 on the outer surface thereof.
The distal end is provided with a flange 14 from which extends a socket engaging portion 15 which is usually square in cross section. This portion engages within the square recess formed on a standard socket (not illustrated) with the socket being detachably held in position by means of a spring loaded ball 16 on one face 17 of the portion 15 with the ball being compressible into the surface as the socket is engaged thereover.
The handle engaging portion is a hollow cylindri-cal portion having a plurality of spline receivi~g grooves `
18 formed around the inner wall thereof, the number of grooves preferably equalling the number of splines 13.
These grooves extend longitudinally from one end to the other but terminate spaced from the end speci~ical-ly designated 19. ~his end 19 is preferably formed with a square cross sectioned recess adapted to be snap engaged by a conventional socket wrench handle (not illustrated) which extends at right angles from the longitudinal axis of the extension assembly when positioned on the ha.ndle engaging portion 11.
