Figure 13 is a detail view in elevation of disc-positioning plunger and an abutment th which the plunger is adapted to cooperate in positioning the disc at right angles to axis of the odmdrical be preparatory to the soldering hpera'tion.

' turret 17, are associated suitable means, hereinafter described, for introducing bottomformingdiscs into the cylindrical bodies and properly positioning such discs therein. The. cylindrical bodies with their bottom-forming discs carried therein are transferred to an endless conveyor 18 by means of which one end of the cylindrical bodies and the adjacent peripheral margins of the bottom-forminn discs subjected, first, to an acid bath and then to a bath of solder, whereby the discs are'secured to their respective cylindrical bodies, thus producing containers which are delivered to a suitable receptacle, not shown, at the endof the conveyor.

The turret 17 with its associated cooperating elements, is supported by a frame 20, within which a power shaft 21 is journaled, the power shaft having journaled thereon a pulley 22, adapted for connection with a suit able source of power. not shown. In order to start and stop the machine, a suitable.

clutch is provided for locking the pulley to the power shaft 21, the clutch 23 being controlled through the instrumentality of a suitable lever 24; located within convenient reach of the operator. To the shaft 21, is se cured a gear 25, meshing with a gear 26, which in turn engages a gear 27, the gear 27 being in mesh with a spur gear 528, secured to a shaft 29 which is provided with a bevelled gear 30. The bevelled near 30 mesh es with sii'nilar gear 31, carried by a shaft 32 which is suitably journaled in the frame 20 and is provided with a cam 35 and a Geneva gear 3-6 adapted to engage and cooperate with a similar gear 37. the gear 37 being carried by a shaft 38 to which is. secured the turret 17 This turret is channeled as shown at 39 in Figure 9, torelieve excess weight, and is provided with a plurality of equidistantly' spaced pockets 40, four of such pockets bein 9; herein shown.

The hopper. 15 is suitably supported by means of a bracket 4-2. carried by the frame 20, and is provided with a chute 1 3, through which the cylindrical bodies 16 pass in ei'iterin th pockets 4:0 of the turret l'Z'Q In order displacement or ja 'nniing of the a]. bodies 16, due to their being su a tubular magazine 48, adapted for the recep-' tion of a stack orplurality of bottom-forming discs 49 which are adapted to be introduced successively into the bodies 16 at station C while'the turret 17 is at rest. The bottomforming discs 49 are removed from the maga- Zinc 48, one at a time, by means of a reeiproeating finger 51, cut away at its forward end 52 to a depth equal to the thickness of one of the bottom-forming discs 49, and are carried forwardly and positioned within the cylindrical bodies 16 during such time as they remain at rest at station C. As the finger 51 is retracted from the cylindrical body 16, into which the bottom-forming disc 49 has just been introduced, the bottom-forming disc, is usually frictionally engaged by the cylindrical body 16 at diamet'ieally opposed points, and is held within the cylindrical body 16. Should the cylindrical body 16 fail to hold the bottom-forming disc 49 sufficiently to retain the same therein as the finger 51 starts to move to its retracted position, shown in Figure 8, withdrawal of the bottom-forming disc is prevented by restraining means 55. This restraining means 55 comprises a spring pressed plunger 56 carried within a chamber 57, formed in a suitable housing 58into which the lower end of the magazine 48 fits. The plunger 56 is urged to its position shown in Figure 8 by a coil spring 59, surrounding the plunger stem 60 which projects through the housing 58 and carries at its upper end a stop 61 which serves l l' 6 'tl' lil' to lCuLlIl tie p un ei a n1 nn me man )(31 57. The plunger 56 is, at its lower end, )rovided with a rounded head 62 which will permit the bottom forimng disc 49, as it is carried forward by the linger 51, to readily lift the plunger 56 against the spring 59 so as to allow the bottom-forming disc, about to be introduced into the cylindrical body 16, to move forward in au'unobstructed manner to a position in front of the plunger 62 and well ifin 'er 51 is carried b reci iroeatin slide 65, suitably mounted within a guide 66, carrled by the frame 20, the s lde 65 belng linked to an oscillating arm 67, pivoted at its lower end to the frame 20 and connected by means of a rod 68 to an operating lever 69. This lever 69 is pivoted to the frame 20, and carries a roller 70, adapted to traverse the face of the cam 35, by means of which cam the operating lever 69 is moved in one directimi. said lever being moved in an opposite direction by a tension spring 71 which is connected at its respective ends to the lever 69 and'a suitable arm or anchor 72 carried by the frame 20.

After the bottom-forming disc 49 has been inserted into the cylindrical body 16 at station C, as shown in Figure 11, it becomes necessary to swing the bottom-forn'iing disc at an angle to the axis of the cylindrical body into the angular position with respect to said axis, as shown in Figure 12. his displacement or swinging of the bottomforming disc, from its position shown in Figure 11 to its position shown in Figure 12, is effected while the cylindrical lody is being carried from station. C, shown in Figure 10, to station .l shown therein, and is accomplished by means of a stationary cam or member 75 (Figures 8 and 10), carried by the semi-circular guard 45 and so arranged, adjacent one end of the turret 17, that the outwardly projecting edge of the bottonrforming disc 49 engages the cam and is gradually moved thereby from its position shown in Figure 11. to its position shown in Figure 12. Thus, by the time the cylindrical body reaches station D, the bot tom-forming disc carried by that body is so positioned as to be acted upon by a suitable disc positioning mechanism l'iereina'ltcr described, whieh is employed to move the bot-- tom-forn'iing disc 49 from its position shown in Figure 12, to its position shown in Figure preparatory to the soldering operation The disc-positioning mechanism is actuated by the cam and includes a plunger head 76 carried bya sha l: '77 on which is slidably mounted a pressure head 78 which is adapted to be urged into intin'iate engagement with one end of the cylindrical body 16 by means of a compression spring 79, arranged intern'iediate the pressure head 78 and a reciprocating slide 80 to which the shank 77 is secured. This reciprocating slide 60 operates within a guide 81 (Figure 1,), suitably connectod to the frame 20 and is linked to one end of the operating arm 69 that the cam 35 positively moves the pl ungor head 76 in one direction, whereas the spring 71 moves it in an opposite direction. lit station D, a stationary abutment 83 is carried by the frame 20, the abutment 83 being so located adjacent one end of the turret 17 as to align with the plunger head 76 and the pockets 40 as the cylindncal bodies 16 are brought successively into position to receive the plunger 77 at station D. As the cylindrical bodies 16, carrying their respective bottom-forming discs 49, are brought succes- 77 enters such cylindrical bodies, whereupon the pressure head 78 engages the'edge of the cylindrical body and urges the same longitudinally of its axis into intimate engagement with the abutment 83, as shown in Figure 13. As the plunger head 76 continues to move forward it engages the bottom-forming disc 19 and moves it from its position shown in Figure 12 to its final position at right angles to the axis of its cylindrical body 16, as shown in Figure 13. Inasmuch as the bottomforming discs 19 are so dimensioned as to snugly fit the interior of the cylindrical bodies 15, such discs, when forced into their final respective position, shown in Figure 18, will remain so positioned during such time as is required to transfer the cylindrical bodies, with their bottom-forming discs positioncd therein, from the turret 17 on to the conveyor 18 and through the acid and solder baths, respectively. The plunger head 76, upon reaching its forward position shown in Figure 13, is retracted by the spring 71 as the cam 35 continues to rotate preparatory to the next succeeding forward movement of the plunger head 76, and after said plunger head has been withdrawn from the cylindrical body 16, the turret'17 is so rotated as to move the cylindrical body with its bottomforming disc to station E, at which point the cylindrical body drops by gravity from the turret on to a chute 84 suitably supported by the frame 20.

During movement of the cylindrical body from station I) to station E, the succeeding cylindrical bodies are transferred from their statienstotheirnextsucceedingstations. During movement of the cylindrical bodies from station D to station E, they are retained within the turret pockets by a keeper or guard 85, shown as carried by the chute 8i and curved at its lower end so as to insure against jamlining of the cylindrical bodies as they pass from the turret 17 on to the chute 84.

As the cylindrical bodies '16, with their r spective bottom-forn'iing discs 49, are inoduced into the chute 841', the lowermost of such bodies within this chute is removed, the removal talcing place simultaneo sly with the introduction of the plunger head 7 6 into the cylindrical body 16 at station D. The means for removing the lowermost cylindrical body 16 from the chute 84, is shown in Figures 1 and 10 as a depending arm88, carried-by the slide and provided with a horizontally disposed foot 89 which is adapted to engage one end of the lowermost cylind rical body within the chute 8 1 and push such body horizontally to an inclined chute 90, as-

' soeiated with the conveyor 18. As the cylindrical bodies are transferred from the chute it becomes necessary to insure their being delivered to the chute 9O 1n a perpendicular relation to this chute, so that they may be properly fed to the conveyor 18, and in order to insure proper delivery of the cylindrical bodies to the chute 90, there is arranged at the upper end of the chute 90 a deflector plate 91 which engages the forward end of the cylindrical body as it passes from the chute 84, and so deflects the same that it drops on to the chute 90 in a right angle position with respect thereto.

The conveyor 18, to which the cylindrical bodies 16 are fed down the inclined chute 90 under the action of gravity, is secured at one end to the frame 20 and is supported at its other end bymeans of a supporting frame Thisconveyor 18 includes a horizontally dis posed frame member 9 1- to which is journ aled, adjacent the frame 20, a shaft 95 provided at its lower end with a spur gear )6 and at its upper end with. a bevelled 87. The bev elled gear 97 meshes with a similar gear 98 carried by a shaft 99, journaled in the frame- 20. To the shaft 99, is secured a second bevelled gear 100 which meshes with a similar gear 101, carried by the shaft 102 to which the gear 26 is connected. The shaft 95 is provided, intermediate its gear 97 and the frame men'iher 9%, with a pair of sprockets 103 over which pass a pair of spaced sprocket chains 10%, each of which is provided with a plurality of spurs or lingers 105 and each'of which passes, respectively, over sprockets 106 journaled upon a trunnion 107 supported by the frame member 941 at the outer end thereof. Suitably journaled to the frame member 94, is an intermediate gear 108 which meshes with the gear 96 and in turn meshes with a similar gear 110, carried by a shaft 111 which journaled to the frame member 94 and is provided with a pulley 112. The pulley 112 arries a belt 113 which passes over a similar pulley 11d, suitably journaler to the frame member 9 at the outer end thereof, the pulleys 1122 and 11-: being so dimensioned that the stretches of the belt 118 operate intm'niediate the corresponding stretches of thc'chains 104., as shown most clearly in Figures (3 and 7. It will be note-t that, due to the presence of the ii'iterinedi ate 109 the belt 118 will travel in the same dii ction as the chains 104, thereby effecting rotation of the cylindrical bodies during such times they pass through the acid and solder baths, respectively, so as to insure proper application of acid and solder respectively, to the parts to be soldered.

Intermediate the frame 20 and the supporting frame 93, is arranged a relatively shallow receptacle 116 for carrying asuitahle acid, as shown in Figures 2 and 6, the receptacle 116 being supported from the frame member 94: by means of brackets 117, or the like. Beyond the receptacle 116, is arranged a vertically adjustable receptacle 118, within which is carried a quantity of molten solder, as

relation to the guides shown in Figure 7, which solder may be maintained in a molten condition by means of a suitable source of heat such as a gas flame, not shown. lhe receptacle 118 is provided at opposite ends with vertical guides 119 which are confined within guideways 120, carried by the supporting frame 93, the guides 119 being adapted to engage and rest upon cams 121, carried by a horizontally disposed shaft 122, journaled within the supporting frame 93 andprovided with an operating lever 124-. Through the instrumental ity of the cams 121 which cooperate with the guides 119, the receptacle 118. may be raised or lowered to suit varying conditions, as will be readily appreciated.

In order to lower the cylindrical bodies into the acid and solder baths, respectively,

as such bodies are moved along the conveyor 18 by the chains 104, lower and upper o uides 126 and 127 are provided, the guide 126 being secured to an angle-iron 128 c rried by the frame member 9 1, and the ,le 12? being suitably connected to a yoke-shaped support 129 suitably connected to the frame member 9-1. Referring to Figure 2, it will be noted that portions of the lower guide 126 are cut away, thus providing depressions 130 and 131 located directly over the receptacles 116 and 118, respectively. t will also be noted that the upper guide 127 is formed with eX tensions 132 and 133 directly opposite and adjacent to the depressions 130 and 18 1, respectively. Due to the depressions 1230 and 131 in the guide 126 and the presence of ex on the guide 127, the

tensions 132 and loo passage allorded between these two guides, 126 and 127, is a tortuous one, and sure the cylindrical bodies 16 are forced to traverse this tortuous passage by the spurs or arms 105 these cylindrical. bodies as the i movev from one end of the conv f to the other are first lowered a slight distance into the acid bath and then removed there'troin utter which they are lowered to a sh ht A e into the solder bath and then removed therefrom. During lllOVQl'l'ltlltO'f the cylindrical bodies :troiu oneend of the conveyor to the other, they'are supported by a track member 135, suitably connected to the cats oti the yokeshaped supports 129, by means ot which such track member is supported in a spaced 120 and 127, as shown most clearly in Figures 6 and 7.

ilts above stated, the belt 113 is provided. in order to rotate the cylindrical bodies 16 while they are bein subjected to the acid and solder baths, respectively; but in order to positively insure such rotation a plurality of idler rollers 180 are employed. These idler rollers arranged in groups, as shown in Figures at and 5, one group being located adjacent the receptacle 116 and the other group being: located adjacent the receptacle 118. Each of the rollers 136 is 'ournaledupon 1%".

which is pivotally connected intermediate its ends, to the frame member 9 1. These rollers are urged into intimate engagement with the inside of the lower reach of the belt 113 by means of tension springs 138, connected to the respective arms 137; and the belt 113 by these rollers 136 is thus urged into intimate cugagement with the cylindrical bodies as they pass through the acid and solder baths, respectively. Since the belt 113 travels in the direction that the cylindrical bodies are bein carried by the conveyor chains 104-, the cylindrical bodies are rotated as they pass through the acid and solder baths, respectively, with the result that the periphery of the bottomforming discs all) and the lower end margin of: the cylindrical bodies are subjected to a uniform application of acid and solder succcssively. Due to the proper application 01 acid and solder thus insured, non-porous and otherwise perfect joints between the cylindrical bodies and their respective bottoms are insured.

Qperation of the machine is as follows: Assuming that cylindrical bodies are being introduced into the hopper 15, and power from a suitable source is connected to the main drive shaft 21, the intermittently actuated turret 17, into the pocket 40 of which a cylindrical body has been forced from the inclined chute 13 by gravity, carries such body to station C and then pauses. d no to the system of intermittent gearing herein shown as including gears 36 and 37. During such pause, one of the bottom-forminadiscs l9 is removed. from the bottom of the stack within the magazine 18 and introduced into the iylindrical body, previously carried to station C, within which body it remains positioned, as shown in Figure 11, when the finger 51 is retracted. Upon withdrawal of the finger 51 from the cylindrical body at station C, the turret 17 is again moved a quarter turn, whereupon the next succeeding cylindrical body entering the turret is elevated to station C; and the cylindrical l. ody, into which the bottom-forming disc has been previously introduced at station C, is simultaneously moved to station D. During this movement, the previously introduced bott ointorming disc 49 is turned to its position shown in Figure 12 by the cam 75. During the pause of the turret 17, the plunger "4''? moves into the cylindrical body while at station l) and turns the bottom-forming; disc 40 from its position shown in Figure 12 to its position shown in Figure 13. lVhile the bottom-tormino; disc s9 is being turned at station I), the cylindrical body now positioned at station C is being supplied with a bottom-harminn disc 49, in the same manner as previously described. After the plunger 77 is retracted troin the cylindrical body at station D, simultaneous with which retraction the finger 51 is retracted from the cylindrical body at station I is claimed is:

C, the turret 17 is again rotated a quarter turn, thus moving to station D from station C the last cylindrical body to receive a bottomforming disc. During this quarter turn of theturret 17, the last cylindrical body to be introduced into the turret is elevated to station C, and the cylindrical body from Which the plunger 7 7 has just been Withdrawn drops from its pocket, at station E, on to the chute 84 from Which it is later removed by the foot 89, simultaneous With a subsequent movepath of travel afforded intermediate the guides 126 and 127, to dip, first, into the acid bath within the receptacle 116, and then into the solder bath Within the receptacle 11.8, rotation of the cylindrical bodies being insured by the belt 113 as such bodies pass through the acid andsolder baths respectively. As the cylindrical bodies emerge from the solder bath they travel thence to the end oi? the conveyor, during Which travel the previously applied solder hardens and thereby permanently unites the cylindrical body and bottomforming disc to form a container, the containers being permitted to drop from the end of the conveyor as they reach this pointinto a suitable receptacle or the like.
