Q MAGAZINE TOOL Fil ed March e, 1946 s Sheets-Sheet s socket and subsequent manipulation of the wrench to drive or release the screw. When in the position shown in full lines in Fig. l and in Fig. 2, the device may be used as a conventional screw driver; whereas when the handle l is adjusted to the position shown in broken lines in Fig. l, the wrench may be used as an angle wrench with a materially increased leverage resulting from the radial position of the handle with respect to the turning axis of the screw and of the wrench element.
It has been found desirable, in order to prevent the tool from buckling at the pivot joint 8 under misapplied pressure whilevin use in the straight line position, to provide a positive locking means for this adjustment. This locking means, as shown in Fig. 4, consists of a pin latch 16 in the side of the part "I which is urged outwardly by a spring ll. When the stem 6 is in the straight line position with respect to the handle, as shown in Fig. 1 (full line) and Fig. 2, the latch it will register with a socket opening it! in the confronting ear and will be forced into said socket by the spring H. The stem will then be positively locked in the aforesaid position. In any other position of the stem, the latch It will be held in retracted position bycontact of the outer end thereof with the inner face of saidear.
The latch may be released from the socket 18,
so as to permit adjustment of the stem 6, through the medium of a button, is ;which occupies the outer end of the socket opening and projects beyond the outer face of the said ear. The inner end of the button isenlarged so as to provide a shoulder 2|, and the metal of the ear 5 at the 1.
outer end of the socket 18 is upset as indicated at 28 so as to form an abutment for the shoulder which retains the button in the socket against the pressure of the spring H applied through the latch I5. By pressing the button inwardly the latch may be forced inwardly to an extent clearing the socket l8 and releasing the stem for adjustment. As illustrated, the abutting ends of the latch pin Iii andbutton 19 are convexed or beveled at the edge so as to facilitate positioning of the end surfaces at the parting line between the stem and the surface of the ear 5 when the stem is to be adjusted.
Reference has been made above to the notches [5 in the butt end of the tool element l3,. notches are arranged so that when the tool element is normally seated in the socket of the stem 5, as illustrated in Fig. 8 wherein the inner end of the tool element engages a shoulder 22 at the inner end of the socket, the said notches will lie in a plane normal to the axis of the stem which intersects an aperture 23 in the wall of the stem.
, Occupying this aperture is an element 24 which is spherical in the present instance, and the inner end of the aperture 23 is of a reduced diameter precluding passage of the element 24 into the tool socket of the stem While permitting a portion of the element 24 to project into said socket. When the tool element I3 is in the aforesaid normal position in the socket, the element 24, if projecting beyond the inner end of the aperture 2.3, will enter that one of the notches [5 which at the moment registers with the aperture. It will be noted that the aperture 23 is located at the juncture of two of the sides of the polygonal tool-receiving socket of the stem 6 and that in anyposition which the tool element 13 may occupy in the stem socket, one of the notches I 5 will register with the aperture 23 as described.
Mounted on the outer cylindricalgsiu'f-ace.v of
These 4 the stem 6 is a sleeve 25 which forms with the surface of the stem a chamber 26 in which the element 24 is housed. The sleeve is adjustable on and longitudinally of the stem 6 and the wall 21 of the chamber 26 is inclined to the longitudinal axis of the stem and is arranged so that when the sleeve is moved in one direction, in the present instance toward the outer end of the stem,
the wall 27 will engage the element 24 and by camm'ing action will tend to force the element 24 inwardly of the aperture 23 and into the registering notch l5 of the tool element I3. In this manner the element 24 will be positively retained in a position locking the tool element It in the stem.
I When the sleeve 25 is moved in the opposite direction on the stem, the element 2-41 is released and is permitted by reason of the increased diameterof the chamber 25 to move outwardly in the aperture 23 to an extent clearing the inner restricted end thereofas shown in Fig. 1G, whereupon the tool element 13 is freed for withdrawal from the stem socket.
The sleeve 25 further comprises a recess 23 in the inner surface and at one end thereof, and in this recess, which in the present instance extends completely around the inner periphery of the sleeve, is mounteda split ring 29 of spring sieel which is stressed so as to exert pressure against the outer surface. of the stem 6 as illustrated in Fig. 9. Thereby the element 29 creates friction between the sleeve and the stem which tends to retain the sleeve in adjusted position on the stem. 1
A modification of this tool element retaining device is illustrated in Figs. Y11 and 12 wherein the stem to of the tool,which contains the polygonal tool element socket as described above, is threaded at 3i and is providedwith a sleeve 32 having internal threads at one end as indicated at 33 for operative engagement with the threads 3!. This sleeve is provided with the typical inclined surface St at the inside thereof which functions as a cam to force a spherical element 24a into the inner end of its retaining aperture 23a and into the notch ifia of a tool element 13a Which corresponds to the element [3 described above. By rotating the sleeve 32 itmay be caused to move longitudinally of the stemto engage or release the element 34a as may be desired. The use of the threads 3 l3 3 insures .a proper retention of the sleeve in the longitudinally adjusted position and in this case a frictioning device such as described in the previous embodiment is notv re quired. v
Still another device for retaining the tool elements of the character of l3 previously described is illustrated in Figs. 13 to 16 inclusive. In this case the retaining'element 24b is controlled by L a sleeve 35 which is mountedfor simple rotation about the stem 6b. This sleeve is provided with a slot 36 into which the enter end of the element 24b projects, the slot being narrower at one end than at the other and the sides of the slot being thereby inclined to the dn'ection of movement of theslot .asa wholewh'en the sleeve 35 is rotated. The larger end of the slot 36 is sufficiently narrower than the'm'aximum diameter of the element .24b to preclude escape of this element from the aperture 2% in the stem 6?), butxwhen the element 24b occupies the said larger end of the slot, it is permitted to move outwardly to an extent freeing the tool element |3b as shown in Fig-.15. When the sl'eeve'35 is turned to bring the element flbxinto the smaller end of thegslot. the-inclined sides 31 of the latter act as cams to force; the element flb inwardly into the tool elementretaining position as illustrated in Fig, 14. .It will'bejapparent that in this case the element 24b operates as a stop to limit the rotational movement of the sleeve 35 in both directions.
. A stil irurthe too -r aini means is 1111 45.- trated in Figs. 1'7 ,to 19 inclusive. ,In this case the sleeve 38, which is mounted for rotation after the mannerof the sleeve 35 described above. is provided with an aperture 39 which in one position of the'sleevewillgregister, with the retaining element 240 as-shown in Fig. 18. In this position of the sleeve the element .240 is permitted to move outwardly to an extent freeing the tool element 13c as previously described. When the sleeve 38 is turned however, the inclined sides 4| of theapertureifl act as cams to force theelement 24c inwardly to an operative position as illustrated in Fig. 19 wherein the element is retainedby thelin ner surface of the sleeve 38. In this instance the rotational movement of the sleeveis limited by an element 42 which seats in a recess 43 ir the outer surface of the stem 60 and the outer end .portion of which enters a slot 44 in the sleeve 38. This slot is sufficiently narrow-to preclude escape of the element 42, and the manner in which it operates to limit the *angularimovement of the sleeve stood, however, that it is contemplated that.
other forms of tool element than that shown in Fig. may be included in the device, and'one such element is illustratedin Fig. 6 of. the drawings. The butt end- 45 of-this element-41 is provided with the typical polygonalform adapting it to the socket of the stem portion ofthe tool holder, and this polygonal portion is;a'lso; provided with notches 46 corresponding to the notches I5 of the previously described element l3. This butt formation is typical of all of the tool elements that might be included in the kit with an exception described below. The outer end of the tool element 41 is provided with a suitable socket 48 for a threading die 49.
As previously described, the outer terminal end of the stem 6 of the tool is externally hexagonal as indicated at II. This provides for application to the end of the stem of a socket wrench element 5i as shown in Fig. 7, this element 5| having the conventional hexagonal base socket 52 which receives the hexagonal terminal portion ll of the stem. It will be apparent that other types of tool element may .be employed without departure from the invention.
It will be apparent that each of the devices described above provides an efficient, economical and readily manipulated means for positive retention of the various tool elements which may be included in the kit. It is apparent also that the device as a whole constitutes a compact and highly flexible tool having desirable characteristics of simplicity of form and manufacture combined with the ruggedness and durability required in a utility tool of the type involved.
