This invention relates to new and useful improvements in tools embodying among other characteristics a handle designed for detachable engagement with the shanks of 5 different tools.

Another object of the invention consists in the provision and arrangement of means whereby the tools may be extended for appreciable distances from the handle.

An additional object of the invention consists of ratchet connections for the handle and tools therefor.

With the above and other objects in View, the invention further consists of the follow- 15 ing novel features and details of construction,

to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a longitudinal sectional view taken through my improved handle construction.

Figures 2, 3 and 4 are horizontal sectional views taken on lines 2-2, 3-3 and 4:4 respectively'through Figure 1 of the drawings.

Figure 5 is an elevation of a detachable extension sleeve for the handle construction.

Figure 6 is a detail sectional View taken through a socket member for use in conjunction with the adaptor.

Figure 7 is a bottom plan View of the socket. Figure 8 is a longitudinal sectional view taken through a reversible form of tool shank. Figure 9 is an elevation of a form of tool and shank therefor.

Figure 10 is a view similar to Figure '9 of the drawings of a tack puller or claw.

Figure 11 is a fragmentary elevation of a tool shank carrying a saw blade. 1

Figures 12 and 13 are fragmentary elevations of the attaching shanks of angers and countersinks.

Referring to the drawings in detail wherein like characters of reference denote corre- 5 sponding parts, the reference character 10 indicates generally the handle of the improved tool and which is provided with a bore 11 extended throughout the major portion of its length and referably cylindrical in cross secore 11 is in turn in communication with acounter bore 12 within one end of the handle and which accommodates a bearing sleeve 13 therein. A bolt 14, passed through the bore of the sleeve 13, disposes the shoulder portion 15 therefor, as defined between the bolt proper and a-th'readed extension 16 therefor flush with the enlarged end 17 of a sleeve member 18 telescopically associated with the handle 10 and Within the bore 11 thereof. The threaded extension is adjustably connected with the enlarged end Wall 17 of said sleeve. 7

The outer exposed and projecting portion 19 of the sleeve 18 is shaped in conformity with the outer side wall contour of the handle 10 to simulate the general shape of the conthe inner periphery thereof encircling the adjacent portion of the sleeve 18. Teeth 22, radially disposed upon the outer surface of the sleeve 21, are adapted for selective contacting engagement with the fingers 23 of pawls or dogs 24 swingably mounted Within recesses 25 in the portion 19 of the sleeve 18 whereby a reversible ratchet driving connection is established between the handle and sleeve.

The shanks, such as indicated at 26, of the tools disclosed in Figures 9 and 13 inclusive, may then be insertedwithin thelbore of the. sleeve 18 in the manner shown in Figure 1 of the drawings. Notches or other depressions, such as indicated at 27, arranged upon one side and disposed at spaced intervals throughsurface thereof to engage the adjacent end of for the latter mentioned ratchet member operthe portion 19 and for other purposes to be able at rightangles to and in conjunction with brought out in the further description of the said handle. present invention. 2. A tool construction comprising a handle The bore of the barrel is shaped in conhaving a longitudinal bore, a sleeve revolv- 70 formity to and longitudinal with the bore of ably mounted within the bore of the handle the sleeve 19 and held in such position by the having a rectangular bore, a ratchet driving locking pin 28 passed through an opening 32 connection established between the handle therein. A ratchet sleeve 33, rotatably and sleeve, a detachable extension sleeve carmounted upon the outer surface of the barrel ried by the first mentioned sleeve forming a 75 30 between the adjacent ide of th bos 01 guide and extension for the extended por-' flange 31 and a stop collar 34, carries ltertions of tool shanks carried within the bore nately o rabl pawls 35 l tiv ly n ag d of the first-mentioned sleeve, a locking elewith ratchet. t th 36 for d on d di ment carried by the first mentioned sleeve to 15 posed in a circuitous cdurse about the outer ff looklng connection of the extension surface of said barrel as evidenced from the Sleeve n OOl Shank therewith, an enlargeill t ti f my i ti i Fi 3 f ment revolvably mounted upon the extension th d a ing sleeve, a ratchet connection established as be- The so k t nd 37 f an extension or h dl tween the extension sleeve and enlargement,

3 If desired, a sleeve member of'the con- 1 figuration shown in Figure 8 of the drawings may be substituted in lieu of any of the tool shanks 26 whereby the tool may be operated after the manner of an automobile drill.

40 Obviously the shanks of socket wrenches and y other tools may be adequately accommodated within the bores of either the sleeve or barrel.

The latter also cooperates with the sleeve in providing an extension therefor.

45 The invention is susceptible of various changes in its form, proportions and minor details of construction, and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

50 Havingthus described the invention, what i is claimed is 1. A tool construction comprising a handle having a longitudinal bore, a sleeve revolvably mounted within the bore of the handle 55 having a rectangular bore, a ratchet driving 12o connection established between the handle and sleeve, a detachable extension sleeve carried by the first mentioned sleeve forming a guide for tool shanks extended through the bore of said first mentioned sleeve, a locking element carried by the sleeves having engagement with the extension sleeve and tool shank, a ratchet member carried by and operable in conjunction with said extension sleeve 55 and first mentioned sleeve, and an extension
