SOCKET WRENCH HEAD AND STAKING DEVICE Filed Oct. 25,1946
BY- E MW PM .ATTORNEYS Patented Jan. 16, 1951 so'cksr warscg DE Mar'shazlbVamWink-le, Jrroc'anpism -N aiipl'iatitaotrottrat, 1946, serial-Wa oner):- L
2 Claims.
This inventior'i relats to a 'so'cket wrenehsana particularly such a wrench in whicli' is embodied a staking device-"for closing the upper threads of a nut into close engagement with the'bolt threads while the nut is""sti1l" engaged by the wrench;
Aiiotherobject o'f'the inventionis to provide such a wrench roi-"manuai-"o automatic] operatioii'in which the"lockingforce can befaccuratly determined arid"m'a'd e u'riiformfor" any desired number 'oi'bper'a'tio A further object "is -tdproiiide a wrench of simple and durable construction in which the stakingtool is removableand replaceable.
Another object consists in providing certain improvements in the form," construction, and arrangement of the several parts whereby the above named and other objects may effectively be attained.
A practical embodiment of the invention is shown in the accompanying drawings, in which Fig. 1 represents a vertical section through the wrench and nut, in the position assumed when the nut has been screwed home on a bolt;
Fig. 2 represents a horizontal section on. the line 11-11 of Fig. 1, looking in the direction of the arrows;
Fig. 3 represents a bottom plan view of the wrench;
Fig. 4 represents a top plan view of the staking tool;
Fig. 5 represents a side elevation of the staking tool;
Fig. 6 represents a bottom plan view of the staking tool;
Fig. 7 represents a vertical section, corresponding to Fig. 1, with the parts in the position assumed when staking force has been applied to the wrench to deform the top of the nut;
Fig. 8 represents a horizontal section on the line VIII-VI1I of Fig. 7, looking in the direction of the arrows, and
Fig. 9 represents an enlarged detail vertical section through the nut and bolt when the staking action has been completed, parts being broken away.
Referring to the drawings, a socket wrench head I has a double-hex nut-engaging socket 2 and a square upper socket 3 for engagement with any suitable manual or automatic turning means, the squared end of the latter being shown at 4. Above the socket 2 thehead is provided with a cylindrical recess 5, having a diameter no greater than-the minimum diameter of the socket 2, and terminating upwardly in the shoulder 6.
HEAIi Afiil S I AKW VICE" is shown as "an" anfiulai K ght of "the recess E andh a-V arofinuifisuow'er end'an annular "ridge EL-form v 5 by beveled innerand outer surfaces joinedat a' slightlyroiihd' 'p''akf' Tue angleofthe inner bevm maybe if utef-"bvelfis preferably steeper,
1'0 ucli'thatit cafi'be "inserted-through the socket 2' aaa wm ha'vasiiug rrieubn fit in th -recess' 5 with its upper end resting against the shoulder fif The inner diameter of the tool (is slightly-greater "t 'diain" 'er'or anybowon which In operation, the wrench head and staking tool are assembled as just described, the head 20 being mounted on a turning means, such as an automatic wrench driver with controllable torque, the wrench is applied to a nut 9 to be tightened on a bolt Ill, and the driver is operated to screw the nut home against the work 25 piece II. The socket 2 is of less depth than the nut, so that when the parts are in a position shown in Fig, 1, the application of a blow or series of blows axially of the wrench head will drive the ridge 8 into the top of the nut while the wrench head moves down correspondingly around the nut to the position shown in Fig. '7. The depth of the depression [2 in the top of the nut, and the corresponding inward displacement of the adjacent metal, can be regulated accurately by an experienced operator, or by theadjustment of automatic hammering means in connection with the driving tool. Since the staking tool is, in efiect, an integral part of the wrench head, it is always accurately located on the top of the nut, and the nut may be spun on freely and then staked to lock it firmly against accidental displacement.
The wrench shown herein is particularly usef ul in the application of slotted-head nuts of the types shown in Place Patent No. 1,734,445 and in Van Winkle Patent No. 2,431,627 (the latter type being shown in the drawings). In these nuts the upper part is divided into segments which are thrown inward to grip the bolt threads due to a cantilever action in the nut when it is screwed home. When the tops of such nuts are staked by the present tool the locking effect can be greatly increased without increasing the torque, but the segments have sufiicient resilience a"' height approximat The' outef'dianietr of the-"tool 1- and that the depressions in their upper surfaces? have been of various shapes, either continuous (annular) or discontinuous. The ridge 8 shown herein is believed to be a preferable form for most purposes, but the provision of an annular row of more or less separated projections, of
end of a driving device, a cylindrical recess communicating with said lower socket and having a diameter equal to or slightly smaller than the minor diameter of the socket, said recess terminating inwardly at an annular shoulder, and a hollow cylindrical staking tool fitted in said recess with its upper end bearing against said shoulder, said tool having a co-axial annular ridge projecting from one end, the diameter of the tool being no greater than the diameter across the flats of a nut on which the tool is to be used, and the diameter of the bore being greater than the maximum diameter of a, bolt on which said nut is to be screwed.
arcuate or other shapes, is "intended to be in- I cluded in the term projecting element.
A socket wrench having points of similarity to that disclosed herein but designed to effect staking of the end of a bolt or stud forms the subject matter of my concurrently filed application, Serial No. 705,506, now issued as Patent No. 2,525,386.
It will be understood that various changes may beresorted to in the form, construction and arrangement or" the several parts without departing fromthe spirit and scope of my invention, and.
hence I do not intend to be limited to the details herein shown and described, except as they may.
2. A tool according to claim 1 in which the annular ridge lies closer to the bore than to the outer surface of thetool.
