Be it known that I, Josnri-r REN AYo'rTn, a subject of the King of `Grreat Britain, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements Vin Hand- Tools, of which the following is a speciti cation. j j

The invention relates to. .improvements in hand tools, such as Wrenches, and the like.

)ne of thekobjeets ofthe invention is to provide a neat, convenient and etlicient tool that may be used as a Wrench and for Vother similar purposes.

Another object is to provide a tool having an extension handle that can be elongated or contracted with ease and convenience and which may be made to reach and control objects that are `otherwise in conveniently accessible, such as nuts, bolts or the like.

Another object is to lprovide `a tool containing three concentric tubes, the two inner tubes .being Arotatably connected to` gether and. capable `axial extension, the outer tube serving Aas a jacket or supporting means to hold the tool while in use.

Another object is .to deflect the outer end of the tubular jacket and place therein `a tool or .bit holding socket `to receive a ibit or nut socket -and connect the tool-holding socket With the rotatable `tube by an universal joint. j j j.

Another `object is to provide a head at one end Vof the tool. by which .to rotate the inner tube 'to `give .motion `to the bit holder or nutsocket.

Another object is to Aprovide a double, shiftable 1ratchet,between the handle head and the rotatable tube, whereby the `latter anay be positively .rotated `to lthe right, `or to -the left, by shifting `the ratchet controlling means, or the ratchet `may-be rendered ineffective by `movingthe shifting `part to a selected position.

Another object is to provide means for inserting and for holding hard grease with in the tool Vto lubricate the .moving parts.

Other, further .and more specific `objects ofthe invention Will become readily appar ent to persons skilled in the art from a consideration of the following description when taken in conjunction with the drawings, Wherein:--` j l j j 'Figure 1 shows the tool With the handle partlyelongated. j i

In all the views thesame reference characters are employed to indicate similar parts.

The outer holding` tube Ior acket 10 may be knul-led, as at `11, to provide a better surface to be grasped by `the hand, and serves as a. means `by which the tool may be supported .in the hand of the operator. The lower free end of the jacket 10 is laterally deiected, as at 152, and contains a rotatable tool-holdint),l socket A rotatable tube member 14, `concentric with the tube 10 and located. therein, is provided `on its end with means by `which it is. pivotally connected to the univenfnl `joint `member 15. The coperatingjoint member is connected to the end 1G of the socket part 123, so that the socket 13 may be rotated by rotation of the tube 14. rlhe tube member 14 is axially slotted, as at 17, and a blade 1S, fixed to the inner tube member 19 may be slid within the slot 17. The blade 1S is held inthe tube 19 bv means of a pin 20. lV hen the tube 1.9 is l/rotated, the tube la .is rotated .thereby through the instrumentality of the blade 18 'which is Within the slot 17 of the other tube member. lVhen the tube 19 is moved axially, `out of the tube 11i, as shown in Fig. l, the blade is still Within the slot 1'? andthe tube lll may, therefore, be rotated from any point, by the blade 18, secured to tube l1). T he upper end ot' the tube lf) contains a head 21 and on the inside of the headl is a tube 22, secured thereto' by a pin 2?). The upper part of the head 21, as at 2li, .is made hekagonal in shape, over which a hexagonal ring 25 is freely slidable. The ring is cut away,atone of its angular surfaces, and a spring' clip 2G is placed Within the cut-away part to produce more or less friction with the parts over which the ring 25 is slid-able to canse section taken on line it to remain inthe position in which it is eil'orts of the spring 8?).

placed. rlihe upper face of the head 2l is provided with ratchet teeth 27 and a hexagonal ring 28 freely rotatable on the tube 22 and always wit-hin the slidable ring 25 is Y provided with corresponding ratchet teeth 30. Another head 31, forming part ot the handle, is slidably mounted on the tube 22. The head 31 is hollow and contains an open oiled spring 33, secured in place on tube 22 by pin Si, to hold the lower end 35 of the head 31 in intimate contact with lthe upper surface of the ring 28. rlhe upper surface of the ring 2S is provided with ratchet teeth 36 that are inclined in the opposite direction to the ratchei teeth 2T and 30. Now when the ring 25 is in the position shown in Figs. 2 and 3, the head 31 may be rotated effectively, clockwise or to the right, to positively rotate the socket 13, and when rotated in the opposite direction the ratchet teeth 3G and 3.7 will move the head 31 outwardly against the resilient Now when the ring is moved axially into the upper position, shown in Fig. l, the ratchet tecth 29 and 30 are 'tree to perform their desired and intended function so that when the head 31 is rotated to the left, or anti-clockwise, the socket 13 is thereby rotated in the saine direction, the head being moved outwardly against the resilient action of the spring 33, when it is rotated to the right, so that by holding the ring 25 into either of the positions, the socket 13 may be positively rotated in either direction. It it is desired to remove a nut from the bolt, then theI 2:3 is moved upwardly, in the position sho n in'Aig. 1, and the ratchet teeth 27 and ai) will permit the head 31 to move ircely to the right and will positively move the socket 13 to the left. lt it is desired to screw a nut onto a bolt, then the ring 25 is moved into the position shown in Figs. 2 and 3, whereupon the ratchet teeth 3G and 37' are free to act. N hen the ring 25 occupies an intermediate position, covering both sets ot ratchet teeth, then both of the ratchets are disabled and the socket 13 may be positively rotated in either direction by the rotation ot the h andle head 31.

In the upper end of the handle head 31 is a screw 39 for securing in place a transversely extending rod 40, which serves as convenient and removable means by which the head 31 may be rotated. The central portion of the rod is knurled, as at Ll1, for convenient location or" rod l() in the head and for offering a surface for contact with the inner end of the screw 39 to more securely hold the rod in place. The tube 19 is preferably groovcd,vas at 12, at intervals, so that when the screw 43 is backed out, the tube 19 may be drawn out of the surrounding coperating tube member lei. The screw 4:3' is then set into one of the grooves, and

the extended parts are thus held in the position unt-il it is desirable to contract them again, as shown in Fig. 2. This may be convenient when the bolt. nut, or screw dcsired to be operated upon, is located at a remote point and at such distance that it cannot be readily reached when the tool is in its contracted condition.

An orifice 45 is made at the lower end o'fi the tube through which hard grease may be forced, so as to lubricate the universal joint 16 and the other moving` parts within the jacket 10. A similar orifice -l-G is made in the head 31 through which hard grease or other lubricant may be inserted within the head.

A socket #1S or other forni ot bit or nut holder may be inserted in the tool socket 13 and held in place by a screw 15), there being a groove 50 made in the socket 18 within which the screw 49 engages tor the purpose of holding it in its operative position. Any tool, other than the socket iS may be in`- sorted in the operative socket lil, such as :i bit, drill, tap or the like.

, When the tool is not in use, the rod Al() may be removed from the head 31 so that the device will occupy a relatively small space.

Thilo I have herein shown a single embodiment of my invention for the purpose of clear disclosure, it will be manifest, to persons skilled in the art, that changes may be made in the general arrangement and coniguration of the parts within the scope of the appended claims.
