This invention relates toimprovements in socket wrenches, and more particularly to a novel self-adjusting socket wrench which is arranged so thatas the wrench is pressed against the work the jaws adjust themselves to properly grip the element to be turned, the primary object of the invention being to provide a simple and eflicien wrench of this kind which will eliminate the need for several difierent wrenches when work.- ingwith such as serrated ring and round nuts, which frequently vary somewhat in size, so that a corresponding number of wrenches is required or the job is attempted with inadequate wrenches with consequent damage to the nuts and the Work.
Another important object of the invention is the provision of a self-adjusting socket wrench of the above indicated character which is especially adaptable for use with a rotary air gun andthe like.
Another important object of the invention is the provision of a self-adjusting socket wrench of the above indicated character which is com-'- prised of a minimum number of simple component parts in a rugged and mechanically efiicient assembly.
Other. important objects and advantageous features of the invention will be apparent from the following description and accompanying draw ings, wherein, merely for illustrative purposes, a specific embodiment of the invention is set forth in detail.
In the drawings- Figure 1 is a general transverse vertical section.
Figure 2 is a bottom plan View, and,
Figure 3 is a horizontal section, taken on the line 3- 3 of Figure 1.
Referring in detail to the drawings, the numeral 5 generally designates the cylindrical body of the illustrated wrench, formed in its upper end with an axial driving tool socket 6, and in its'lower end with an axially aligned jaw chamberl, adjacent which the surrounding lower portion of the body 5 is diametrically expanded as indicated at 8.
The jaw chamber 1, which is substantially cylindrical, comprises an upper portion 9, which may be of substantially the same diameter as the socket 6 relative to the body 5, merging at its lower end in a bevelled or flaring shoulder portion It, whose wider lower end merges into an enlarged diameter cylindrical portion ll opening through the lower end of the body.
The socket 6 and chamber 1 are connected by an axial bore I Z'haVirig a reduced upper end portion defining a st'hp shoulder I 4 at the upper end of the bore. In the boi e [2 works the smooth cylindrical shank l5 of the jaw carrier It, which is fbriiiedbn its lower end with a hollow inverted frustrh=conical aw'wxpaaaifig part IT, which, iiithj'e normal position of the wrench, extends somewhat below the lower end. of the body 5 to engage such as the serrated ring or flange on the-rouiidnut: Theupper part or the shank I5 is reduced, as indicated at 20 to define a; shoulder 21 and provide space for a helical expanding spring 22,- which is circump-osed on the portion 20 and compressed between the stop shoulder M and the shank shoulder ZI- so astb normallypos'itioh the jaw carrier in the "depressed position shown inFigure" 1; A screw 23; having a fiat head 24 larger indiariieter than the upper end of the borel2 is-threaded downwardly iiito the upper end of the-shank l5 to hold the same in place in" the here;
The adjustable jaws 25 are positioned in the space in the jaw chamber 1 betweenthe jaw expanding portion H and shank portion 15 of the jaw carried 16; and the surrounding wall portionsfl, I8" andllof the chamber 1, and are sup'portab'ly carried by the carrier [6, which has formed thereon or otherwise suitably secured thereto the laterally projecting annulus 26, having, inthis instance, four equally circumferentially spaced radial" pins: 21.
Each of the four; or: other suitable number of jaws 25 which may be provided, are segmental in cross section and. comprise an: upright upper portion 28, aria outwardly flaring intermediate portion 29 for camming. or wedging engagement with the flared jaw ohamber'surface l0; and the upright lower portion 29', whose lower, end normally depends below the lower end of the carrier l6; as shown in Figure l,
The upper portions 28 of the jaws are formed at their inward sides with grooves 30 conform ably securing the annu1us 26 between adjacent pins 27,- with the pins disposed between the facing edges. of adjacent jaws so as to space them, whereby the jaws are suspended from the annulus in properly spaced working relation.
For holding the jaws 25 in place on the annulus 26 a spring ring 3| is circumposed about the upper jaw portions 28 and is seated in a retaining groove 32 formed in the outer sides of the portions 28 below the annulus 26 For holding the jaws 25 normally in expanded position, a spring ring 33 is seated in grooves 34 formed in the inward side of the flaring intermediate portions 29 of the jaws, The inward sides of the lower ends of the jaws are provided with inwardly projecting serrations or teeth 35 for cooperative engagement with the nut or ring serrations.
In using the above described wrench, the hollow frustro-conical lower or guide part I! of the jaw carrier [6 is concentrically engaged with the nut or ring to be tightened and downward pressure is exerted on the body 5, sufiicient to compress the spring 22 and cause the carrier 16 to move upwardly in the body and thereby force the outer flaring surface 29 of the jaws 25 to engage the flaring surface of the chamber 1 and thereby compress the jaws 25 together and force their serrations or teeth 35 into engagement with the nut serrations, whereupon axial rotation of the body 5, produced by suitable means, will tighten or loosen the nut. Elevating the body 5 permits the spring 22 to expand and produce expansion and disengagement of the jaws 25 from the nut.
