WRENCH FOR REMOVING THE BACKS OF WATERPROOF WATCHES Filed March 27, 1945 'INVENTOR. LL OVD GH/GL/ER/ .4 rz omvEr Patented Feb. 3, 1948 WRENCH FOR REMOVING THE B ACKS OF WATERPROOF WATCHES Lloyd Ghiglieri, Oakland, Calif.

Application March 2'7, 1945, Serial No. 585,042

This invention relates to wrenches.

An object of my invention is to provide an improved wrench having a number of relatively adjustable jaw members which are arranged for engagement with devices of different sizes and shapes.

Another object of my invention is to provide an improved wrench having a number of angularly arranged jaw members which are capable of being relatively adjusted to different positions, whereby the wrench may be used to engage with devices of difierent sizes and shapes, as for instance, the screwable backs of various types of waterproof watch cases.

A further object of my invention is to provide an improved wrench of the kind characterized, having novel means for mounting a number of adjustable jaw members whereby different sets of such members may be conveniently substituted one for another to permit the use of the wrench with waterproof watch cases or other devices having different shapes or constructions.

Other and further objects of my invention will be pointed out hereinafter, or will be indicated in the appended claims, or will be obvious to one skilled in the art upon an understanding of the present disclosure. For the purpose of this application I have elected to show herein certain forms and details of a wrench representative of m invention; it is to be understood, however, that the embodiment of my invention herein shown and described is for the purpose of illustration only, and that therefore it is not to be regarded as exhaustive of the variations of the invention, nor is it to be given an interpretation such as might have the effect of limiting the claims, short of the true and most comprehensive scope of the invention in the art.

In the accompanying drawings:

Fig. 1 is a plan view of a wrench embodying the preferred principles of my invention;

Fig. 2 is a side elevation of the wrench, showing diagrammatically, by the broken lines, a watch case engaged by the adjustable clamping jaws;

Fig. 3 is a bottom view of the wrench, showing diagrammatically, by the broken lines, the watch improvements in case and the adjustable clamping jaws engaging therewith;

Fig. 4 is a sectional view taken on the line 4-4 of Fig. 1;

Fig. 5 is an end view of the wrench;

Fig. 6 is a sectional view taken on the line 6--6 of Fig.

2 Claims. (Cl. 81-6) Fig. '7 is an enlarged sectional view taken vertically through one of the clamping jaws; and

Fig. 8 is a perspective view of one of the clamping jaws.

Referring to the drawings, the numeral l designates a shank having one of its ends threaded and. its opposite end positioned between and secured by screws 2 to upper and lower supporting plates 3 and 4. Pivotally connected to the supporting plates, as at 5' and 6', are two pairs of arms 5 and 6, the upper arm of each pair being positioned between the upper and lower supporting plates 3 and 4, and the lower arm of each pair being positioned beneath the lower supporting plate 4.

Rotatably carried at the outer ends of the pairs of arms 5 and 6, respectively, are jaw supporting members 1 and 8 which are each provided with end openings or sockets for receiving removable jaws 9. As shown in Fig. 7, the jaw supporting members I and 8 embody an assembled structure comprising an inner tube 10 which carries a spring pressed ball II that engages with a jaw'9 and normally holds the latter in the socket in tube ID. A sleeve l2 positioned around the lower part of tube l0 engages with the spring which urges the ball ll into firm engagement with the jaw 9. The upper part of the tube Ill is externally threaded and passes through the outer ends of arms 5 and through an intermediate nut [3 which holds a small pin 14 in an annular groove IS in the lower end of a pivoted post l5. The annular groove I3 is intersected by a vertical groove I3a which permits the small pin 14 to be lodged in the annular groove l3 when the parts of the jaw supporting member are assembled. By turning the post 15 through a certain angle the groove l3a is moved to a position where it cannot receive the pin l4, thus preventing the post from being detached from tube Ill, but still allowing it to turn inside the said tube. The same structure is provided with respect to the other jaw supporting member 8.

The body portion of each of the jaws 9 are of general cylindrical shape and each is formed at one or both ends with shoulders or the like for engaging with a. device to be rotated or firmly held, as for instance the removal part A of a waterproof watch case. It is contemplated that the jaws 9 or others like them be provided with differently shaped and constructed ends so as to permit the use of the wrench with devices, slots or notches of difierent shapes and constructions. The upper ends of the posts l5 are provided with diametrically disposed threaded openings,

and operatively engaging therewith is an adjusting screw I6 having its opposite ends provided with left hand and right hand threads. Centrally secured to the screw I6 is a knurled disc I! which when turned in one direction rotates the screw to actuate the free ends of the opposed pairs of arms and 6 away from each other, and

when turned. in the opposite direction. rotates the screw to actuate the pairs of? arm's about. their pivots toward each other. Thus the jaws 9 may ,be adjusted toward or away from each other to:

suitably position them for engagement with elements of difierent shapes or'size's'. rotatably extends through a slot in anen'd of" the upper supporting plate 3, and its periphery; is:

disposed where it can be conveniently engaged for manipulation by an operators' thumb.

Loosely mounted on the shank l is av tubular handle l8 which is secured at its forward end to an elongated plate I9. The forward end. ofv the plate l9 carries a j'aw'supporting member '20 which has a jaw 21 d'etachably carried. thereby.

The jaw 21 is similar to the other jaws 9' and 9,

toward and away from a plane" passing vertically through the jaws 9 and 9.

'Iihreadedon the end of theshank I is an ad justing sleeve 22, which interiorly" carries a nut 22 (see Fig. 4) that engages with the right hand threads on the outer end'of the said shank. The adjusting sleeve is also internally: threaded as at 22a, the latter threads beingLihen'gag'ement' with the left hand threads provided on' the tubular handle l8; Thus byturning the sleeve 22 to the right the tubular handle I81" and thejaw 21 are moved inwardly, and when turned in the opposite direction thesaid tubular handle and the said. jaw are actuated" in: tl're opposite' direction. I V

By the adjustment of the jaws.9, 9; through the manipulation of the disc I1, and the adjustment of. the jaw 2! by means of the, adjusting sleeve 2'2,.the said jaws may beirelativel'y adjusted to engagewith devicesor elements ofidifierentsizes or shapes. By substituting. one set. of jaws. for another set having different shapes and. con.- structions, the wrench may beused t0 unscrew or hold removable'backsof watch cases of diiferent makes. Similarly, by employing jawsr or, other types of engaging members,- the wrench may: be satisfactorily used for various other purposes. It is thereforeto be understood: that the term jaw as-herein employed: shall be: con:- strued to include pins, sockets, or: other types The disc' IT of engaging members adapted to connect with or fasten to different devices or elements.

What I claim is:

1. In a wrench, a supporting structure havin a pair of relatively adjustable jaws mounted at one end and a threaded shank secured to its other end, means for adjusting the jaws with respect. to. one another, an adjustable tubular handle members-lidably.niounted on the shank and having one end threadedand' its opposite end -formed with an extension, a third jaw carried by the extension, and an internally threaded sle'eve ext'en'din'g; around the threaded end of the shank and the threads of the tubular handle 1 member; whereby when the sleeve is rotated the tubular handle member is moved to adjust the third jaw with respect to the other two jaws.

2. In a wrench, a' supporting structure comprising an upper plate and alower' plate provided with a guide slot, lever arms pivot'ally mounted onthe supporting structure, eachsupporting a jaw carrying member; means for ad justingthelever arms withrespect to eachother whereby the jaw carrying members may be rela"-' tively adjusted, a shank secured at one end to the upper and lower plates and having-"its other end provided: with. right hand threads, a tubular handle member adjustably mounted on th'e shank and having left hand'threa'd's at one en d'and -an extension: on its. opposite: end, a thirdjaw carrying member secured-to: the: shank s extension: and having an extension .slidably positioned in the guide slot of the lower plate of the supporting structure, and aninternally' threadedisleevelhaving two. distinctive sets of threads. one set engaging-withthe left handthreads of: the tubular handle member-and the other set engaging with the right handthreads of the shank,v whereby the tubular handlem'embermay be'moved;.when the sleeve is turned, to'adjust' the third'jaw carry ing member with respect to the other jaw carrying members.
