.6 .Glaims.

This invention relates "to wrench jdevices and,

particularly what I termsa turret .head Wrench, whereina plurality of wrench :elements 10f different diameters are supported :in :a :head and means is provided fort moving the wrenches: into extended operative position and, wherein, the

'head includes a handle portion which, in itself,

can be utilized as'a wrench. .still'more particu larly, the invention deals with a wrench device of :the character described, wherein tensional means is employed to: normally support the tools ininoperative position withinthe environment of the head of thetool.

The novel features of vvthe inventionrwill .be

"best understood from the following description,

when taken together :With the accompanying 'drawing, in'which certain "embodiments of the invention are disclosed "and, inwhich, the-separate parts are designated by suitable reference characters in each of thewviews and, inwhich:

Fig. 1 is a'side and sectional viewiof one form r of tool which I employ, illustrating ctheihandle member in"'full and dotted *Llinesinttwo diiferent positions, with parts ofrthe iconstructicnubroken "away.

Fig." 2 is =2. sectionr'onfthe line 12-12 :otfig. :1. Fig. 3 is a :sectional view r through za zmodified form of tool with the .handle tmember rbroken away and alsoindicating that parts Iinra' different position. in dotted lines; :and

Fig. 4 is a section'on thexline 4-4wsofrl33ig..8. In Figs. 1. (and .2 :ofith :drawingl have shown at ID a .tool "body 'or'*headi'havingsaihexagon bore I I extendingtherethroughiandieccentrically disposed with respect tothe! head; the rbodyIhaving a plurality of hexagon bores 12 arranged upwardly extending sleeve portion l5 thereof.

In normalposition o'fthetoolspr wrenches l3, they are contain'edwithin upper and'lower surfaces of 'thehead land, when it is desired to use one of the tools, 'a handle member 1 i isfinserted 'in the bore "H andpin' this operation; a iradiallyjofiset lug portion or 'dogl' l Bifor examrlile, H on the long rend Fl "of 'the handle memberr-eninto the extended position, as shown at l3 in ..Fig.1 of the drawing. The end l1" includes "a tensioned ball [9 to establish frictionalengagement of the handle member in the bore I l. The other short end ll" "of the handle member also has a projection or dog I8 and a ball I 9' facilitating coupling of the short end with the head when it is desired to extend thelong end of theha-ndle member in the horizontal direction or what might besaid to beradially with respect to the head [0.

Either oneof the spring actuatedballs I9, [9 will establish sufficient frictionalengagement to support the head on the. handle memberin either useof the tool.

Considering Fig. '2 of "the drawing, it will appearthat the six sides of the bore .H face each iagon handle member-will be. in alinement with one of the tools l3 so that, in moving the handle member into the. bore-l I .andaxially'of the head, the dog I 8, I 8' willengage and project the tool registering with :said ,dog. When the handle member "is detached, the :previously projected :tool [3 can be returnedto collapsedvposition by pressing inwardly by hand.

.In'Figs. 3. and 40f thedrawing, I have shown another form of construction, wherein 2!). rep- :resents ahead, generally'similar to the head [0, withthe exception that the sleeve =l 6 is dispensed with as is also the groove I 4 and spring l7.

.Further, in Figs. :3 and-4,121 short hexagon bore 112i 'Tl'S providedi and this bore is arranged con- :centricallywith respect to the body 20. Eccen- "trically arrangedwithirespect to thebore 2| are a plurality of hexagon bores 22 of differentdiameters in which are arranged "hexagon tools 'or wrenches 23. 23 haveiex'tended collars or fiangesmwhichform .seatsforsprings. 25, whichmormallysupport the wrenchesin :raisedretracted position, as seen #at'the right of Fig.3.

Inner ends 'of the wrenches The 'bore '2! opens into a large diameter bore 26 inwhichisfixedyby a set screw 27, a sleeve -28 whichforms abearing support for a key pin *29. The pin "29 has a co1lar3fl fixed thereto adjacent-the hexagon end 3| of' the pin. This collarforms a'seatfor a spring 32 arranged in thesleeveZt and normally serving to support the pin29 in operative position in the hexagon socket orbore 2|.

Keyed to the: pin "29 is a disc -v3 3,' 'to which ls fixed a'fira'dially extending-hexagon handle" memsilient means, the the st e1n of the handle member is arranged, and

ber 34. The disc 33 has a depending sleeve 35, substantially of the same diameter as the body 20 and serves to house the upper end portion 32 of the tools, as will clearly appear from a consideration of Fig. 3 of the drawing.

Also fixed to the disc 33 andarranged within the sleeve 35 is a tool operating pin 38 having a rounded lower end 31. This pin is adapted to engage any one of the six tools or wrenches 23 and is so positioned on the disc 33 as to engage all of the wrenches, regardless of the size thereof. Whenever desired, the handle member 34, including the disc 33, can be raised against the action of the spring 32 into the dotted line position shown in Fig. 3 and, in the raised position, can be rotated with respect to the body 20 to brin the operating pin 36 in registering position with any one of the six tools or wrenches supported in the head 23, after which, the disc 33 can be released and the spring 32 will operate to extend the selected tool or wrench in the manner illustrated at the left of Fig. 3 of the drawing. lhe body 25 and disc 33 are preferably knurled to facilitate relative rotary movement one with respect to the other.

When the handle member is in the operative position shown in full lines in Fig. 3, the handle member is definitely keyed to the body by engagement of the hexagon end 35 with the hexagon bore 2|. However, in the raised position of the handle member, 3! clears 2|.

It will be apparent that the handle member I! forms a seventh wrench which can be utilized in either position and inserted into the bod Hi through either end thereof.

The end ll"-l'l" of the handle member and the end SI of pin 29 may be said to form stems operating in the hexagon bores I I and 2 1, respectively in rotation of the tools.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:
