zr @ys United States Patent O 2,993,397 MAGAZINE-TYPE SOCKET WRENCH Frank O. Albertson and Jens Axel W. Madsen, Sioux City, Iowa, assignors to Albertson & Company, Inc., Sioux City, Iowa, a corporation of Iowa Filed Aug. 14, 1958, Ser. No. 755,086 13 Claims. (Cl. 81--125) This invention relates to magazine-type socket wrenches such as are used to remove a series of identical nuts from machine elements and particularly to remove the nuts from a vehicle wheel when it is desired to change wheels and tires.

It has previously been proposed to provide a sockettype wrench having an elongated magazine therein for accumulating in aligned stacked relation a plurality of substantially identical nuts as they are removed from the studs of a vehicle wheel or the like, with means for holding a -first nut in position to be re-applied to a wheel stud, and with additional means for holding the remaining nuts in the magazine removed from the stud, but in readiness' to be advanced singly to the lirstementioned position where they may be re-applied to a stud. 'Ihe aforesaid socket-type wrench also has provision for manually releasing the forward nut in the magazine to move under spring pressure to the end position in the magazine Where it is accessible to a stud. The application of the nut to the stud and its removal therefrom are effected by a power tool having a readily separable connection with the socket wrench to speed the operation of the wrench and to make its operation less tiring to the operator.

For purposes of illustration the present invention will be described with reference toa similar power operated magazine type socket wrench, but it is to be understood that the invention may be applied with equal facility to a hand-operated tool having one of the forms usually Y employed for tools for removing nuts from wheels, etc.

This invention has for its principal object the provision of mean, in a magazine-type socket wrench, for automatically advancing the outermost nut in the magazine to a position wherein it is accessible to a stud to which it is to be applied, and for automatically holding all but the end nut in the magazine in a position inaccessible to the stud while the said outermost nut is being applied thereto. l

More specifically, this invention has within its purview the provision of a magazine-type socket wrench having means for holding an end nut in position for application to a stud, normally ineffective means for holding all but the said end nut in the magazine out of reach of the stud, and with means operable by a nut as it is being threaded upon a stud for rendering the holdin-g means effective.

As a still more specific object, this invention provides a magazine-type socket wrenchvhaving ball detent means lat the end thereof for holding an end nut in a position wherein it is accessible to `a stud to which it is to be applied, a second detent means axially spaced inwardly of the end of the wrench, said second detent means being normally inoperative, and with means, operated by Patented July 25, 1961 FIG. 2 is a longitudinal sectional view of the socket wrench of FIG. l on a greatly enlarged scale;

FIG. 3 is an end elevational view of the socket wrench of FIG. 2 looking to the right in that gure;

FIG, 4 is an end elevational view of the socket wrench of FIG. 2 Vlooking tothe left in that ligure;

FIG. 5 is a view of the left-hand portion of the socket wrench of FIG. 2 showing a plurality of nuts stored therein and a stud in proximity thereto;

FIG. 6 is a greatly enlarged fragmentary longitudinal section similar to the forward portion of FIG. 5, but with the detent means' rotated relative to one another to show them in axially aligned position;

FIG. 7 is a view in section similar to that of FIG. 5, but showing the end nut of the plurality of nuts applied to a stud; v

FIG. 8 is a greatly enlarged fragmentary longitudinal section similar to the left-hand end of the magazine of FIG. 7, with the ball detent means rotated to show the balls in axially `aligned relation;

FIG. 9 is a fragmentary side elevational view in section of the left-hand portion of the magazine of FIG. 2 showing the manner in which a plurality of long nuts may be stored therein;

FIG. 10 is a greatly enlarged fragmentary view of the left-hand portion of FIG. 9 showing the detent means thereof rotated with respect to one another to be in axial alignment to illustrate more clearly the operation thereof; and

FIG. 1l is a fragmentary longitudinal sectional view of the left-hand portion of the magazine as shown in FIG. 2, with one of the long nuts partly removed from the magazine and the remainder held by one of the detents.

Inasmuch as the same magazine socket wrench is shown in a number. of different figures, corresponding parts thereof will be given the s'ame reference characters to simplify the description thereof and to facilitate the eX- planation of the operation of the invention.

Referring now to FIG. l, the invention is shown applied to amagazine-type socket wrench in the form of a tubular body 20 having one end constructed to receive the drive shaft 21 of an electrically-operated power tool 22, and its opposite end, as will be made apparent hereinafter, arranged to receive, or release, as the case may be, a plurality of substantially identical nuts. The tubular body.20 may be held in operation by a sleeve 23 rotatably mounted on body 20,

' `adapted to receive a similarly eonligured end of the drive the end nut as it is being threaded upon a stud, for'renderv power operated tool therefor shown in dot-dash outline;

`shaft. 21 ofthe tool 22 such that rotation of shaft 21 is imparted through the adaptor 25 to body 20. ySaid adaptor 25 is designed to be applied and removed from the end of -shaft 21 with any well-known snap action fastening means. v

The end-fof body 20 removed from adaptor 25 is reducedfin diameterto provide a male portion 27 which tits into the counterbored end 28 of a tting 29 which may be ofdifferent hardness from that of the body 20 and which has an opening 30 therein of a cross-sectional contour identical to that of opening 24 in body 20 and constituting an extension thereof.

Sleeve 23 is mounted on bronze bushings 31, 32 press lfitted into suitable counterbores at the ends of the sleeve and retained against axial movement relative to body 20 by snap rings 33 and 34. Said bushings 31 and 32 are rotatable on the .exterior surface lof Vtubular body ,20.y A space 35 is provided between the interior of sleeve 23 and the exterior of body 20 into which grease may be introduced through an appropriate fitting 36 to lubricate the bushings 31 and 32.

Within fitting 29 and tubular body 20 is a helical spring 37 the right-hand end of which as viewed in PIG. 2 bears against a washer 38 abutting on the inner end of adaptor 25 and the other end of which, as viewed in FIG. 2, encircles the right-hand end 39 of a plug 40, the other end as shown in FIG. 2 at 41 being enlarged to have a sliding fit in opening 24 and to form a shoulder 42 against which the left-hand end of spring 37 may bear. The length of the plug 40 measured from shoulder 42 to the right-hand end thereof as viewed in FIG. 2 is such that when plug 40 is moved to its extreme right-hand position in FIG. 2 it will contact washer 38 before spring 37 is compressed to its solid height. Plug 40 therefore provides a means for safe-guarding the life of spring 37. Referring now to FIGS. 2 and 3, two axially spaced series of ball detent means are mounted in ttin-g 29. The first series is typified by ball 43 and comprises balls 43, 44 and 45 disposed 120 apart and each centrally located in a face of the hexagonal opening in the fitting 29. Said first series, as is apparent from FIG. 2, is located in a plane which is near the left-hand end 76 of the fitting 29.

The second series is typified by ball 47 and comprises balls 47, 48 and 49 similarly disposed 120 apart and centrally disposed with respect to alternate sides of the hexagonal opening Said second series-of balls is axially spaced from the first series by a distance approximately equal to the axial length of a nut, that is, the planes passing through the centers of each series of balls are spaced axially relative to one another a distance approximately equal to the faxial length of a nut to be received in the opening 24.

Each ball is received in a radially disposed opening I such as is illustrated by opening 50, the inner end 51 of which is tapered and thereby reduced in diameter to prevent the ball from passing completely through thevopening to the interior of the fitting. The balls are adapted to assume `an outer position in their respective openings 50 as typified by ball 47 in which the ball does not project into opening 30, and an inner position typified by ball 43 in which the ball projects into opening 30 and constitutes an obstruction to axial movement of nuts in the opening.

Referring next to FIGS. 2 and 5, the means for controlling the radial positions of the balls will now be described.

Disposed over theopenings balls 43, 44 Iand 45 is a ring 52 havingacounterbore 53 at its forward end and a frusto-conical-surface 54fat its rearward inner end. Between the two' series 'of balls is a second ring 55 having a frustoconical surface 56 on the interior thereof and a small land 57 which assists in centering the ring on the fitting 29. Rings 52 and 55 are urged apart by a wave type spring 58. The frusto-conical surfaces 54 and 56 are thus disposed between the two series of balls and the force of springy 58 urges surface 54 against balls 43, 44, `and 45 and surface 56 against'balls 47, 48 and 49. The camming action produced'by the surfaces 54 and 5-6 thus tends to move the two series 'of balls radially inwardly into the path of movement of any nuts which may be stored in the openin'gv30'.

50 and the first series'of Y Ring 55 is urged to the left as viewed in FIGS. Zand 5 i 4 l movement of collar 60 to the right as viewed in FIG. 5. Thus, spring 59 is compressed between flange 61, which is axially fixed by snap ring 62 with respect to fitting 29, and ring 55 thereby exerting an axial force against said ring 515 in a direction to urge the ring away from balls 47 48 and 49 and at the same time, through contact with wave spring 58, urging ring 52 toward balls `43, 44 and 45. In this manner la camming action is established between surface 54 on ring 52 and balls 43, 44 and 45 constantly tending to urge said balls radially inwardly while at the same time relieving any camming action between surface 56 and balls 47, 48 and 49 so that the latter balls are normally free to move radially outwardly out of the path of movement of the nuts which may be stored in the opening 30.

An outwardly extending fiange 63 on fitting 29 serves partly to assist in centering ring 52 on fitting 29 and partly as a limit stop to prevent ring 52 from sliding off said fitting 29 in the event that there should be no nuts or other means in the opening 30 to force the balls 43, 44, 45 radially outwardly to hold said ring on the fitting 29.

A spacer ring 64 is inserted in the space between rings 52 and 55 and is of sufficient axial length to prevent said rings 52 and 55 from being brought so closely together as to compress wave spring 58 to its solid height which of course would be damaging to the wave spring. The

free height of spring 58, i.e., its axial uncompressed l r58 remains undeflected when an axial force is impressed upon ring 52 in a direction to the right of ring 52 as viewed'in FIG. 5. This means that rings 52 and 55 will move together as a unitary member against the resistance of spring 59 except under special conditions hereinafter -to be described.

The operation of the device will now 'be described.

. It is Kassumed that the opening 30` and the opening 24 together will serve as a storage space or magazine for a plurality of nuts of the type commonly used to secure a vehicle wheel to its hub. Such nuts are illustrated in FIG. 5 at 66, 67 and 68, each of which is hexagonal and fits with a relatively loose sliding fit within the correspondingly hexagonal openings 30 and 24. Each nut furthermore is formed with a tapered end 69, 70, 71, respectively, designed to engage a lfrusta-conical opening 72 in the wheel body 73 through which extends the'stud 74 of the vehicle wheel hub 75 to which the wheel is to be secured.

Assuming for purposes of illustration that the conditions shown in FIG. 5 are present, that is, there are three nuts in the openings 30 and '24 and that these nuts are to be applied to the studs 74 of a vehicle wheel hub, said nuts 66, 67 and 68 will be held in contacting relation to one another by the lforce of spring 37 acting against the shoulder 42 of plug 40, the plug in turn bearing against the rearmost nut 68 to urge it and the intervening nuts against nut 66 in `a direction outwardly of opening 30. Nut 66 is restrained from moving outwardly, however, by the first series of detents 43, 44, 45 which is urged radially inwardly into the path of movement of nut 66 bythe cam surface 54 on ring 52, the latter in turn being urged to the left as viewed in FIG. 5 into camming relation with respect to balls 43, 44, `45 by spring 59 and the intermediate ring 55 and spring 58. The radially inwardly directed `force developed by spring 59 through the ring 52 and frustoconical surface 54 is greater than the radially outwardly directed force developed by the tapered end 69 of nut 66 and the raxial force directed thereagainst by spring 37 through the intervening plug rounding the fitting 29 Vand having an inwardly extending 'flange `61 which engages the outer surface of litting129 40`ad nutsV 67 and 68. All `of the nuts therefore willbe heldin the openings 30 and 24 under theseconditions with asliding fit. A snap ring 62 'on fitting 29 ud in readiness to be applied to their respective studs.

acceso? It may be noted that the left-hand end of nut 66 as viewed in FIG. 5 is in relatively close proximity to the end face 76 of the itting 29 and that the stud 74 therefore may project into contact with nut 66. To apply a nut 66 to a stud 74 therefore, said nut is brought into alignment with the stud and the power tool 22 is energized to turn the tubular body Z0. At this stage the second series of balls 47, 4S Iand 49 may be disposed in their radially outward positions as shown in FIG. 5, wherein they lare out of contact with the nuts in the opening 30 and hence interpose no resistance to the forward movement of the nuts out of opening 30. It is contemplated that the operator will press axially upon the tubular body 20 to bring the forward face 76 of the fitting 29 into abutting relation with the ladjacent surface of the Wheel 73 and in so doing will cause the stud 74 to push the nut 66 and the immediately adjacent nuts 67 and 68 backwardly into the opening 24 against the action of spring 37. Such backward movement of the nuts in the openings 30 `and 24 does not in any way interfere with the threading of the nut 66 on stud 74 since spring 37 will maintain a steady pressure upon the nut and will cause it to be threaded upon the stud 74 and moved axially out of the opening 30.

During the movement of nut 66 out of the opening 30, tapered surface 69 on the nut will cam balls 43, 44 and 45 radially outwardly and, through the contact between the balls 43, 44 and 45 with the frusto-conical camming surface 54 on ring 52, will urge said ring rearwardly, that is, to the right as viewed in FIG. 5, and through the relatively stiff wave spring 58 will transmit such rearward movement to ring 55 against the resistance of spring 59. The rearward movement of ring 55, in turn, will cause the frusto-conical cam surface 56 thereon to engage the balls 47, 48 and 49 and to urge said balls radially inwardly until they assume a position wherein they engage the tapered surface 70* on the adjoiningnut 67. Said balls 47, 48 and 49 therefore serve to hold nut l67 and all nuts remaining in the magazine 30, 24 against movement outward while the nut 66 is being secured to stud 74. After nut 66 passes balls 43, 44 and 45, said balls are free to move radially inwardly under the action of spring 59 upon the ring 55, spring 58- and ring `52 to cause the frusto-conical cam surface 54 on ring 52 to compel such radial inward movement of the balls. Said balls, therefore, are in position to block movement of the succeeding nut 67 out of the opening "30. During the movement of rings 52 and 55 to the left as viewed in FIG. 5, under the action of spring 59 as aforesaid, balls 47, 48 and 49 are released to move radially outwardly to free nut 67 for axial movement Vtoward the balls 43, 44 and 45, under the action of spring 37 and hence such movement will proceed until nut 67 occupies the position previously occupied by nut 66. The

foregoing sequence of operation for removing a nut from the opening 30 is repeated for nuts 67 and 68, etc.

To remove nuts from studs 74, as, for example, when 1t s desired to remove wheel 73 from the vehicle wheel hub 75, the fitting 29 is pushed over a nut with the balls 43, 44, 45 in the first series cammed outwardly and the balls 47, 48, 49 in the second series cammed inwardly. The power tool 22 and tubular body 20 .are then rotated reversely to back a nut 66 olf its stud 74. While 'this operation is proceeding, surface 76 of the fitting 29 is held against the outer surface of the wheel 73 so that the removal of the nut 66 results in an axial movement Y thereof in the opening 30 toward the right as viewed' in FIG. 5. The stud 74is of sufcient length to compel nut 66 to move backwardly until its tapered end 69 passes ball 43 whereupon said ball and its associated balls 44 and 45 in the front series will be moved radially inwardly by the cam surface 54 on ring 52 and the balls 47 will be released for radial outward movement in the manner previously described with reference to the application of the nuts to the studs. The rearward movement of the nuts continues into the chamber 24 until the chamber s filled, or until all of the nuts have been removed, whichever occurs rst. Each time the tting 29 is removed from a stud the nuts in the openings 30 and 24, regardless of their position prior to such removal, will be moved forwardly to the position shown in FIG. 5 by the spring 37 so that the end nut 66 will bear against the balls 43, 44 and 45 and will maintain a position in readiness for application to additional studs.

For a better understanding of the relationship between the two series of balls and their cooperating rings 52 and 55, reference may be had to FIGS. 6 and 8 which show the two series of balls as they would yappear if they were in the same axial plane. FIG. 6 depicts the balls in the position that they occupy when one or more nuts is held in the opening 30, and FIG. 8 shows the positions that the balls will assume when a nut is being advanced out of the opening 30 but has not yet passed the ball 44.

To render the tool of this invention more universal in its application, it is desirable that it be capable of accommodating nuts of different lengths. It is clear from FIGS. 5 and 7 that nuts of the length therein shown or shorter can readily be accommodated by the tool hereinabove Idescribed. The same construction of tool, however, is equally `as readily adaptable for use with longer nuts than those shown in FIGS. 5 and 7. The relative positions of the various components of the tool when it is used with long nuts are shown in FIGS. 9, l0 and ll, to which reference is now made.

For purposes of illustration it is assumed that it is desired to use the tool of thisinvention with nuts approximately twice the axial length of the nuts of FIG. 5. Such long nuts are shown at 77 and 78 in FIGS. 9 and 11. It is readily' apparent that when nut 77 is disposed to the right of the first series of balls 43, 44 and 45 as shown in FIGS. 9 and ll, the tapered surface 79 will bear against the first series Vof balls 43, 44 and 45 in precisely the same manner as tapered surface 69 of nut 66 bears against said balls as shown in FIG. 5. It may be recalled that balls 47, 48, 49 under those conditions are free to move radially outwardly and hence d'o not in any manner interfere with the rearward extension of the nut 77 past the second series of balls 47, etc. As the rst nut 77 is advanced out of the openings 30, however, balls 43, 44 and 45 will be cammed radially outwardly thereby forcing ring 52 backwardly against spring 58. Ring 55, however, is not free to move backwardly since balls 47, 48, 49 cannot move radially inwardly, and hence spring 58 will be compressed in an axial direction by rin-g 52 while both series of balls occupy their radially outwardly disposed positions. This condition is shown more clearly in FIG. l0 wherein both series of balls are shown for illustrative purposes as lying in the same axial plane. n

After nut 77 passes ball 47, the latter will be forced radially inwardly by ring 55 and the compressed wave spring 58, spring 59, being weaker, yielding, to permit this action. This condition is shown in FIG. 11, the secondv series of balls 47, 48 and 49 being held in their radially inwardly disposed positions to hold the nut 78 against axial movement until the tirst series of balls 43, `44 and 45 are liberated by nut 77 passing thereby. The liberation of the first series of balls permits the ring 52 to be moved forwardly, that is, to the left as shown Ain FIG. 11, to cam the rst series of balls radially inwardly while freeing the second series of balls for radi-al outward movement. Spring 37 thereupon urges nut 78, through the intermediary of the plug 40, toward the first series of balls where the nut is then held against further axial movement out of the fitting 29 until required.

Although only two nuts of the longer type are shown in FIGS. 9 and 11, it is understood that the tool may hold many more nuts and that the number of nuts held by the tool has no bearing on the operation of the two series 7 Y of balls as they hold the nuts in the tool and release them automatically one at a time as needed.

Removal of long nuts from the tool will follow a procedure which will be the reverse of that described with reference to the application of long nuts to studs, the end or outermost nut coming to rest against the outer series of balls 43, 44, 45.

The use of the tool shown described above does not require any manipulation of the collar 60 by the operator either while removing nuts from a wheel or the like, or while reapplying the Inuts to the studs thereof. The operator merely holds the tool with the aid of the sleeve 23 and properly locates the fitting 29 over the nut to remove the nut, or locates a nut within the iitting 29 over the end of a stud to lapply a nut, and then energizes the power tool 22 in the desired direction of rotation thereof to effect a complete removal or engagement of a nut from or upon a stud. This permits the operator to maintain one hand continually on the power operated tool 22 and the other hand continuously on the sleeve 23 and thus promotes a more rapid nut tightening or loosening operation.

Although this invention has been described with reference to its utility as a means for removing, storing and reapplying nuts of various lengths, it is understood that it may be utilized with equal facility for the removal, storage and reapplication of other threaded fasteners, such as cap screws or the like without departing from the spirit and scope of the invention.
