The anode member 25 is cylindrical in form, having fiat ends, and is provided with a central aperture 29 therethrough around which are disposed a series of smaller, equally spaced, parallel apertures 36. The apertures 36 are connected to the central aperture 29 by radial slots 3| which slots define a series of radially projecting tongues 32. on either end, the anode member is provided with a concentric annular recess 33 of rectangular shape in cross section, the bottom of which is providedwith spaced concentric grooves 34 and 35. The ring or circular strap 26 is formed from a thin strip cut to the proper shape and bent to circular form with its ends abutting, and is provided with a series of equally spaced projecting tabs 36. The straps with the anode member 25 sothat the tabs 36 fit into the grooves 33 and 34 and are tightly gripped therein, thetabs 36 of one strap engaging in grooves 34 in alternate tongues 32 and the tabs of the other strap engaging in grooves 35 in alternate tongues not engaged by the tabs of the first ring.

The anode 25and the straps 26 and 21 are assembled in the apparatus, embodying the present invention, shown on an enlarged scale in the various drawings (Figs. 1, 4 and 8). The apparatus comprises a fixture 46 (Fig. 4) movably mounted on a bed 4| and guided for reciprocation thereon by guide members 42 and limited in its forward and rearward movement by stop mem: bers 43 and 44, respectively. The body of the fixture 46 comprises a block 46 and plates 41,

48 and 49, the parts being secured together in dowel pins 56 and cap Figs. 1 and 4. A handle 52 is fixed to the block 46 to move the fixture 46.

To receive and position the straps 26 and 21, the fixture 46 is provided with a nest 53 (Figs. 1,12, 1'1, 18 and 21) formed of a series of concentric telescoping sleeves 55, 56, 51, 58 and 59, the sleeves 56 and 58 being fixed and the sleeves assembled relation by screws as shown in 26 and 21 are assembled to a sleeve actuating member 86. The

provide a plurality of extensions or legs 12 which pass through radial slots 13 in the plate 48 and between the ends of the shoulder portions 66 on the sleeves 56 and 58. The lower ends of the legs 12 of the sleeves 51 and 59 are provided with shoulders so as to engage the legs of the adjacent sleeves, the sleeves being riveted together by means of rivets passing through the lower ends of the legs, as shown in Fig. 21. The lower ends of the legs 12 of the outer sleeve 55 are provided with shoulders 16 which are engaged by the notched ends of rods 11. The rods 11 are reciprocally mounted in aligned apertures 18 and 19 in plates 41 and 48, respectively, and are attached member 86 is movable vertically in a recess 63 (Fig. 8) f in the block 46 and is urged upwardly by a spring 7 85 bearing against the underneath side thereof 55, 51 and 59 being relatively movable thereto.

The sleeves surround an lower portion otwhich is secured in apertures 62 and 63 in plates 48 and 41, respectively. The series of sleeves fits within an aperture64 in the plate 49 which aperture extends through a boss 65 extending upwardly from the plate 49, the boss being provided with a flat surface 66 flush with the top edges of the fixed sleeves 56 and 58. The inner fixed sleeve 58 is provided with shoulder portion 66-66 (Fig. 9) at its lower end and is telescoped within which is likewise provided with similar shoulder portions 66 at its lower end. The lower ends of the sleeves 56 and 58 are sweated into an annular groove 69 in the plate 48, as illustrated in Figs. 2, 7,12 and 21.

The upper ends of the movable sleeves 55, 51 and 59 project above the ends of the fixed sleeves 56 and 58 a distance equal to the overall height of the rings 26 M21 including the tabs 36 and together with the .top edges of the fixed sleeves 56 and 58 form the nest 53 having two concentric circular pockets or recesses 16 and 1| for receiving and positioning the straps 26 and 21, respectively (see Figs. 12, 1'1, 18 and 19). The nest 53 with the straps 26 and 21 in place therein will fitinto the annular recess 26 and 21 with the grooves 34 and 35, respectively, of the anode when the anode is applied, as illustrated in Fig. 19.

The lower part of the sleeves are out out to aligning post 6|, thethe outer .fixed sleeve 56 33 of the anode and and supported on a threaded member 86. The member 86 has a reduced circular portion 88 projecting downwardly into a recess 89 in the member 86 for guiding the member 86. A pair of arms 9| extend outwardly from the member 86 through slots 92 in the block 46, and are adapted to be engaged by the operator to move the member 86 and the movable sleeves 55, 51 and 59 downwardly. The movable sleeves may be moved downwardly to an intermediate position where the sleeves are partly disengaged from the straps 26 and 21 and to a position where they are fully disengaged from the straps. A latch 95 is provided to retain the sleeves in the partly disengaged or the fully disengaged positions. The latch 95 is slidably mounted in a recess in the block 46 and is urged toward the right as viewed in Fig. 4 by a spring 96 which is attached at one end to a stud 91 on the latch and at the other end to a pin 98 secured in the block 46. The latch 95 is shaped with a forked end (Fig. 1) and engages the member 86 at points |66-|66 and is undercut at |62 (Fig. 4) to form a latching surface which will engage the top surface of the member 86 when ,the sleeves are depressed to the intermediate position and the latch member 95 moved' forward. The forward movement of the latch 95 is arrested by the engagement of an oifset portion I63 thereon with the side of one of the arms 9| (Figs. 1 and 5), after which the arms 9| may be moved downwardl until the latch 95 moves further forward and the bottom surface of the onset portion I63 engages the upper surface of the lever 9| and latches the member 86 and the movable sleeves in the fully disengaged position as shown in Fig. 21. A rib or projection I65 on the block 46 (Fig. 1) limits the forward movement of the latch member 95 when the arms 9| are fully depressed. The latch 95 has an upturned handle portion I64, which may be engaged by the operator to retract the latch. V i A pair of locating or aligning pins |61--|61 extend upwardly from the boss 66 and are of such size and are so located thereon as .to fit into a pair of apertures 36 in an anode member 25 when the anode member is applied thereon and to angularly position the anode member accurately relative to the tabs 36 on the rings 26 and 21. To load or feed a strap into the nest 53 of the fixture, a pair of loading devices ||6 are provided, one for feeding the straps 21.

one for feeding the straps 26 and a larger The loading devices 6 are identical except for the size, the

in: a plurality of straps 26. .Theistraps are imserted into thetube III 'one at atime with the tabs 36 directed upwardly and form- :a stack of straps restingone on .top of another andmaintained in place by frictional engagement of the strap with the walls of the tube II I. A piston H5, connected to a piston rodI I6 and a handle H1, is adapted to engage the uppermost strap 26 and, when moved downwardly-to apply a force tothestackof straps to eject the lowermost strap from the tube. Aifiange H8 .is formed on the lower end of the tube III and is provided with a pair of'apertures I Iflpositionedsoas. .to cooperate with the aligning pinsIIl'I on the fixture maligning the loading device with the nest 53 when the loading device .is appliedthereto, as illustrated .in Fig. 12. The loading device, when applied to the fixture as .shown'in Fig. 12, rests on the top edges of the sleeves 55 and .5! and the lowermost strap 26 in themagazine I II is inalignmentwith the circular recess Til-of the nest 5-3 and .may be ejected from the tube III into the recess by .a

downward movement of the piston H5. The loading device I II! is removed after the strap 26 has been ejected and the device for loading the straps 21 maybeapplied and astarp 21 ejected therefrom intothestrap recess 71 of the nest 53.

When the straps 26 and 21 are loaded in the positioning pockets I0 and H, respectively, the upwardly extendingtabs 36 thereon are arranged inrandom position and in .orderto properly align the tabs on one ring with respect to the tabs on the otherring, and with respect to the fixture the straps may be :rotatedabout their centers while in the recess I0 and II and for this purpose a strap turning gauge I20 is used (see Figs. 13, 14,

and 16).

The gauge I20 comprises a cylindrical body member I 2I having a handle I22 and, at its lower end is provided with apair'of axially projecting diametrically opposed lugs I24 equally spaced from the center and a second pair of diametrically opposed lugs I25 equally spaced from the center and angularly displaced from the .lugs I 24. The lugs I25 are formed integral with a cylindrical insert I26 slidably mounted for relative vertical movement in a bore I21 of the member I2! and normally urged downwardly by a spring I28 as viewed in Fig. 14. .The insert I26 is connected to the body member I ZI by a pin I36 which passes through a slot I3I in the insert, the

arrangement permitting the relative upward movement of the insert I26 while the gauge is being applied to the straps 26 and 21 and the fixture 46.

to receive the post 6| and is used for aligning the gauge I20 with the straps 26 and 21 in the nest 53. A foot I24 projects from the bottom of the gauge and is adapted to rest on the surface 66 of the boss 65 to support the gauge at the proper level during the use thereof, as shown in Fig. 16. The lower end of the gauge is .cut away at I to provide clearancefor the pins I61 and to permit a limited turning movement of the gauge.

The lugs I24 are adapted to fit into the recess II of the nest 53 and fit between and engage a pair of tabs 36 on 'thestrap 21 and the lugs I25 are adapted to fit into the recess 10 and fit between and engage a pair of tabs 36 on the strap 26 when the gauge H0 'is applied thereto as illustrated in Fig. 16. In applying the gauge I2I,

'the lugs I24 thereon will seat in the recess ill and engage the strap Z'Land it maybe necessary A centrally located recess I32 is I, formed in the insert I26 and is of a size sufficient to turn the gaugeand the strap 21 before the lugs which may have been displaced upwardly, seatin the recess 10. and-engage the strap 26. The gauge Iw,,,=after the straps are angularly positioned relative to each other therein, may then be turned to properly position the straps with respect to the fixture 40 which condition is brought aboutwhen a notch I36 (Fig. 15) formed ina lower partof thegauge is in alignment with the end I31 of a tab locating gauge I 33 (Fig. 1).

The locating gauge I38- (Figs. 1, 8, l7 and 1.8). is slidably mounted in a slot I39 on the plate 49 of the fixture 4D and is retained therein, by a shouldered screw I43 passing through aslot I42 in the gauge. The gauge I38 is movable toward and away from the post 6! asindicated in Fig.1 infull and dotted lines and is provided with a handle I43 for manually imparting movement thereto. The forward part of the gauge I38 isreduced in vertical thickness and is rovided with converging side walls I44 forming the end I3! which is adapted to fit into the notch I36 and position the gauge I26 in the correct angular relation to the fixture 46. The end I31 of the gauge is also slotted at I46 to receive a tab 36 therein. A portion of the sleeves 55, 5! and 59 are cut away at I48 as shown in Figs. 10, 17 and 16 to provide clearance for the end I31 of thegauge I38 when the gauge is moved into the position shownin Fig. 1.7.

When the turning gauge I26 is removed, the rings 26 and 2'1 are located so that the tabs 36 thereon areapproximatelyin the correct angular position 3111313111 order to check the location of the tabs, and if necessary to more accurately position the tabs 36, the gauge member I38 isused. When the gauge I36 is moved to the left as shown in Figs 17 and 18, the end I3! engages a tab 36 on the ring '26 and receives it in the slot [46 to accurately position the strap 26, and the conj'verging walls I44 of the gauge I38 engage the vertical end walls of two adjacenttabs 36 on the strap 21to accurately position the strap 21.

.After the straps 2-6 and 21 have been accurately positioned by the actuation of the gauge [.38

operation which is to assemble the anode. member thereon. This is accomplished by positioning the anode member above the nest 53 and aligning the aperture 26 thereof with the post 6i and a pair of apertures 36 with the pins I01 and lowering the. anode until it engages and is supported by the upper edges of the nest 53, as indicated in Fig. .19. Portions of the movable sleeves forming the nest 53 and the rings 26 and 27 positioned therein, fit .into the annular recess 33 in the anode member and engage the bottom face thereof and the nest accurately aligns the rings 26 and 21 with the grooves 34 and 35, respectively. The fixture 46 is moved forward to the position shown in Fig. 4 and the plunger I50 of the press I5I is actuated to engage the anode member 25 and move it down until its lower face engages the face 66 of the boss 65. This downward movement of the anode member will cause the tabs 36 of the rings 26 and 21 to movexinto the grooves 34 and 35 and seat against the bottom thereof and be tightly engaged thereby. 'The movable sleeves 55, 51 and 59 will be moveddownwardly by the downward movement of the anode member to the position shown 'in Fig. 20 and will be latched in this position "bythe surface I02 of *thelatoh port engageable with 95. The plunger I50 of the press is raised and the fixture 40 is moved to a rearward position and the handles 9| are depressed to move the sleeves 55, 51 and 59 downwardly to the position shown in Fig. 21 where they are entirely disengaged from the rings 25 and 21 and in which position the sleeves are latched by the portion 103 of the latch 95. The rings 26 and 21 are thus accurately and firmly assembled in the anode member 25 and the assembly may be removed from the fixture by an upward movement thereof.
