4 Claims.

This invention relates towrenches, and more particularly to sets .of wrenches in which each individual wrench may be employed as needed,

:while remaining part of'the'set.

An object of theinvention is to provide 'anovel and improved form of'wrench set; in which a plurality of individual wrenches are movably securediin a novel frame or housing, "whereby any selected wrench may-be employed without disengagementjfrom the housing or frame;

Another objectio'f the invention is to provide a novel wrench set in which there" are a plurality of guide and securing members pivoted ona common pin or shaft, with individual wrenches engaging each of said guide and securingmembers so as to be movable in relation thereto, and so arranged that any selected wrench may be used withoutdisengagement from its guide and securing member.

A further object of the invention is to provide a novel wrench set of the type described, in which the guide and securing members are-eccentrically mounted on the common pin orshaft, allowing any selected guide and securing member and its wrench to be turned substantially out of axial alignment withtherest-of theguide and securing members, for effective use thereof.

' Still another object of the invention is to provide'a novel and" improved wrench set of the type described, in which theindividual wrenches are of the'hexagon typecommonly knownas Allen wrenches, for engagement in matching hexagonallsockets formed in'the heads of screws or bolts;

Still a further objectof the invention isto-provide a novel and improved wrench set of the type described, which is'simple in design, inexpensive to manufacture, and ,whichis highly effective and convenient for its intended purpose:

' Other objects and advantages of the invention will become apparent from thefollowingcdescription of agpreferredembodiment-thereof as illustrated in the accompanying drawings, and in which V 7 long shanks 20 of the individual wrenches.

wrenches, 10, i2,

2 one ofthewrenches with its long shank-extended to an upwardly extended position.

Fig. 6 is a right side elevation somewhat-similar to that of Fig. 3, but show-ing'how the upwardly extended wrench of Fig. 5 hasnow-been turned through an angle of ninety degrees in a clockwise direction, also carrying with it, its individual guide and securing member; 7

Fig. 7 is a perspective view indicating how the wrench set may be grasped in thehand, with one of its wrenches extended outwardly for use.

Where wrenches are-to be-used, it is-necessary to have a set of wrenches in graduated sizes, and

when mingled with other tools in the mechanics tool box, or tool drawer, it frequently happens that thevery size of wrench needed has been mislaid, become separated from the rest of" the set, or otherwise not available, and the resulting inconvenience may cause embarrassing delay. The present invention provides a wrench set in which all the wrenches are mounted in a common holder, yet each-is available for instant use as needed, without disengaging it from the set, merely by turning the desired wrench-out of alignment with the others.

' In order to understand-clearly the nature of "the invention and the best means for carrying'it out, reference may now be had to the drawings, in which like numerals denote similar parts throughout'the several views.

'As'shown, there are a number of individual l4, l6 and I8, each having a long shank 20, and a short shank 22 formingan angle with the long shank, both shanks being thus, integralandformed hexagonal in crossse'ction, which'iscommon to the Allen wrenches. The

individual wrenches

10,12; i4, lG andWB -are thus similar to each other, but differ-in their cross sectional size, as seen best in [Fig 4, and are alsosomewhat different in th-e'length of their "shanks.

Stop lugs 24 project outwardly-from each of the Each of, the individual'wrenches has its long sh ank 20 penetrating loosely through a bore 28 formed through the individual guide and securingmembers or hubs 30, there being thus one such hub 30 for each of the individual wrenches. The shanks 2E9v of the wrenches are thus seen tobe freely turnable in the bores ZBofthe'hubs 30, and at the same time freely slidable axially therein, so that, as seen in Fig. 5, an individual wrench l4 may be elevated by sliding it through its guide bore 28, until its stop lug '24 comes into contact with the hub 30, blocking further movement in that direction of the wrench shank.

As seen best in Figs. 2 and 4, it is preferable to displace the bores 28 in the hubs 30, away from the diametral lines of the hubs, and further it is seen that the larger diameter bores 28 come closer to the outer edges of the hubs than the smaller diameter bores 28. With all the hubs 3i] brought into axial alignment as in Figs. 2 and 4, it is seen that there is a frame pin 32 which penetrates eccentric aligned bores 34 in the hubs 30. The outer ends of the pin 32 may be peened over to retain all the hubs 30 thereon, while yet permitting them to turn freely on the pin. Or, if desired, diameter of the bores 34 4 from, whereby any selected wrench may be brought into extended position for performing operative work therewith, all said wrenches being polygonal in cross-sectional contour.

2. A wrench set comprising a plurality of hub members, means securing said hub members together in assembled relation to each other, a pluin the two outermost hubs 30 may be made a little smaller than that of the other hubs 30,

and the pin 32 pressed thereon to retain the intermediate hubs therebetween. method is used, then it is seen that the two outgrmost hubs 30 will not be turnable on the pin Each wrench is thus individually swivelled, and movable independently of all the other wrenches, so that it is easily moved into any position to permit use at any angle. Fig. 6 shows how any individual wrench may be turned through a full circle of 360 degrees, as indicated by the broken line circle 36 in the direction of the arrows and vice versa.

As shown best in Fig. '7, any wrench, such as wrench l4, may be turned out of alignment with the others, into extended position, so that its short shank 22 is ready for insertion into the socket formed in a nut or bolt for turning the same. From Fig. '7, it is seen that the balance of the wrenches, namely l0, l2, l4, l6, and I8, combine to form a fine grip or handle, the long shanks of said wrenches being grasped by the three fingers 48,

'42 and 44, while the upstanding long shank of the wrench 22 extends between the

fingers

44 and 46. At the same time, the short shanks 22 of the wrenches [6, I2, I6 and 22 lie over and against the thumb 48 of the hand. It is obvious that the assembly is firmly gripped.

It is also seen that any one of the individual wrenches may take the position of the extended wrench M in Fig. 7, and the others will provide a firm grip for the hand. Since the wrenches are secured together, in movable relation to each other to the extent indicated, it is seen that the entire assembly is quite compact, and that it may be inserted into a carrying case, for carrying in the pocket, or disposed in the tool case .in similar manner, in a simple envelope type carrying case having a flap secured in closed position by a snap fastener.

Although I have-described my invention in als and arrangement without departing from the spirit and scope of the invention as claimed.

I claim:

1. A wrench set' comprising a plurality of hub members, means securing said hub members together in assembled relation to each other, a plurality of wrenches, each of said wrenches engaging one of said plurality of hub members, and being individually movable in relation to said hub members without disengagement there- If this latter specific terms, it will be understood that vari- 'ous changes may be made in size, shape, materirality of wrenches, each of said wrenches engaging one of said plurality of hub. members, and being individually movable in relation to said hub members without disengagement therefrom, whereby any selected wrench may be brought into extended position for performing operative worktherewith, each of said wrenches being substantially L-shaped and of polygonal cross-sectional contour, one shank of each of which penetrates slidably each of said plurality of hub members.

- 3. A wrench set comprising a plurality of hub members, means securing said hub members together in assembled relation to each other, a plurality of wrenches, each of said wrenches engaging one of said plurality of hub members, and being individually movable in relation to said hub members without disengagement therefrom, whereby any selected wrench may be brought into extended position for performing operative work therewith, all of said wrenches being substantially L-shaped, one leg of the wrench being hexagonal in cross section for engaging a matching socket to be turned, and the other leg of said wrench penetrating slidably each of said hub members. 7

4. A wrench set comprising a plurality of hub members, means securing said hub members together in assembled relation to each other, a plurality of wrenches, each of said wrenches engaging one of said plurality of hub members, and being individually movable in relation to said hub members without disengagement therefrom, whereby any selected wrench may be brought into extended position for performing operative work therewith, each of said hub members comprising a disc, said securing means comprising a shaft penetrating eccentrically disposed bores formed through each of said discs, parallel to the axis thereof, and each of said wrenches comprising a hexagonal rod bent into substantial L-shape forming two legs, one of said legs penetrating slidablya chordal bore formed in each of said hub members, and the other of said legs forming the operative member of said wrench insertable in a socket for turning the same, and stop means carried by the legs penetrating, said chordal bore, for limiting the outward extension motionthereof. l
