Be it known that'l, 'JosErH' D. LAcRo X, a citizen ofthe United States,- residing at Baltimore, State of Maryland, have-invented certain new" and useful"Improvements in- Spinning Machines' for (Bottles; fully described and represented in. the following specification and the accompanying drawings, forming a part of the same.

This invention relates to "c'aaaim ma:

The particular mechanism herein'shown as disclosing the invention consists of a machine forthe'sealing of separately constructed necks to bottles 'where the combined neck I I l have been sealed.

and bottle form a non-refillable receptacle.

The main-frame of the machine, as shown in Fig. l coi'nprises'the'base 10' and averticul tubularstandard 111': Y

The priucipalpart of the mechanism is mounted "upon a turret frame; which rests upon the base 10 and is adapted'to rotate" about the-verticalstandardll'. The upper part 12 of the turret forms a framework i, ried upon a squarepiston rod. 36jattached to carrying the spinning devices'indicated at 13, 13 and the lower partl4 forms a "frame Work carrying respective holders indicated at 15, 15.

I a d h c0 1 eration of the holders and the spinning dG-g vices are all controlledautomaticallyby movement of the turret through mechanism spective holder cylinders 38 is hung upon the turret frame 12, 12 and terminates in a circular valve seat 43, the lowerface of which has a port opening 44 for each individual pipe. The valve seat 43 rotates with the turret. Keyed to the standard 11, but slidable vertically thereon, are two rings 45 and 46 .held in contact with each other, and the intermediate one with the valve seat 43 by means of springs 47, 47. The lower ring 46 has a pipe 48 attached thereto through which compressed air or other fluid is continuously supplied to a semi-circular channel not shown formed in the upper faceof the ring. The intermediate ring 45 has a similar channel 50 which is in communication with the semi-circular v channel (not shown) in the ring 46. The ring 45 is also equipped with a second annular channel having exhaust outlets 52. It will be apparent that one group of pipes 39 are in communication with the compressed air supply, while another group is in communication with the exhaust channel.

As the turret rotates, therefore, the bottle holders passing through a certain arc will be automatically elevated and will then return to their original loading and unloading position after having completed that part of the rotation.

The springs 47 which effect the packing of the valves may cause more or less vertical movement of the pipe 48 and this is taken care of as follows: A supply pipe 53 is brought into the base of the machine and tapped into a channel 54 formed in the vertical standard 11. This channel terminates at he point 55 on the standard at which a hollow ring 56 encircles the standard with a close sliding fit and receives one end of the pipe 48. This arrangement permits move.- ment of the valve rings, pipe 48 and ring 56 without interrupting the air supply from supply pipe 53. V

The spinning mechanism is'adapted to seal hermetically. together the neck and hottle by spinning a sleeve upon them. The method is disclosed in Figs. 5 and 6, in which thebottle is shown at 60 and the neck at 61. The neck has a groove 61 while the bottle has two similar grooves 60 and 60?.

' The sleeve or ferrule 62 as shown in Fig. 5 is provided with a flange 63 by'which it may be set in position'upon the neck and may also serve to hold the neck in a-linement with the bottle. 6 The sleeve is spun into the grooves 61 60 and 60 firmly binding the neck and bottle together, as shown in Fig. 6; and duringv the spinning the sleeve 62 is drawn or ironed out, as indicated in the two figures. The'ironing out of the sleeve is due to an increasing pressure exerted by the spinning rolls .as they travel down the sleeve. This isa desirable feature of the invention as the pressure of .spinning rolls tends at all during the spinning process, and it also leaves that part of the sleeve joining the neck and the bottle under permanent tension so that the seal will not 01 it will remain so.

The spinning mechanism comprises three coperating devices: plungers operating together to center the neck, to hold it in position upon the bottle, and to clamp the sleeve in position for spinning; mechanism to move the spinning rolls along the sleeve; and mechanism to vary the pressure of the spinning rolls upon the sleeve. 7

The centering and holding plunger-s are shown in Figs. 1, 2, 5 and 6. Centrally located in each spinning mechanism is a rod 64 best shown in Fig. 2. The upper end of this y be hermetic but upper framework 12 of the turret as shown in Fig. 1. The intermediate part of rod 64 is hollowed out to receive a spring 66 and a plunger 67, the lower end of which terminates in a centering head 68. The lower part oi": rod 64 is enlarged to form a cylinder within which a second an'dstronger spring 69 is located and also a second plunger 70, the plunger 67 passing freely through the spring 69 and the second plunger 70. At the lowest point on the rod 64, at the bottom of the cylindrical enlargement, is a tubula jaw 71.

These devices operate as follows: When the bottle and neck are placed in position as shown in Fig. 2 and the holder is elevated by the mechanism previously described, the neck 61 of the bottle first comes into contact with the centering plunger head 68, which acts to center the neck and bottle as the holder continues its upward movement, the

10s movement at the same time driving back the the sleeve or ferrule 62 and clamps that part of the sleeve firmly to the cap. The spinning rolls are shown at 72, 72, in

Figs. 4, 5 and 6, and are carried by arms 7 3. 7 3 pivoted with their respectiveshafts at 74; 74, at equal distances-from one another upon a spinner head 75. The head 75 is carried at the lower end of a rotary sleeve 7 6 which surrounds the plunger mechanism described above and is concentric with the fixed rod 64. I As shown in Fig. 2, the upper 7 end of the sleeve 76 carries a feather 77 and is slidable through a splined sleeve 7 8 to which the gear 34 previously described is keyed. The sleeve .78 rotates .within av bearing formedin the upper turret section and is held in position by a nut? 9. I 1

By [the construction thus described, the splined sleeve 78 communicates a continuous rotary motion to thesleeve 76 and the spinner head 75, at the same time permitting a longitudinal slidingmovement of the sleeve 7 6 and the head 7 5 totake place.. This lon-v gitudinal movement is effected by means of a sleeve 80 which surrounds the sleeve 76 but does not rotate therewith. The sleeve 80 is inset between a shoulder 81 and a bushing 82 carried by the sleeve 76. To the sleeve 80 is attached a rack 83 which meshes with a segment 8d fulcrumed tothe turret frame at 85 and provided with an arm to which is pivoted at 86,.an'actuating link 87. Referring now to Fig. 1, the lower end of the link 87 is attached to a slide;88.mounted upon one of the turret tie rods.,16.-.- Projecting from the slide 88 is a stud carrying a cam roller 89 which moves in a circular cam groove 90 cut in a stationary cylinder 104 attached to the tubular standard 11. V

The pressure of the spinning rolls upon the sleeve is varied by the following mechanism. In Fig. 3, the shafts 7 4 carrying the spinning rolls 72 are shown equipped with arms 91 to which are fastened resilient members 92, 92 terminating at their inner ends in friction balls 93, 93. These balls normally contact with a hollow cone 94 which is slidable longitudinally upon the spinner sleeve 7 6 and the spinner head 75. As shown in Fig. 1, the cone 94 has a groove 95 through which it is engaged by oke 96. The yoke is attached to a rack 9 which engages a segment 98 fulcrumed at 85. To an arm 99 forming a part of the segment 98 is attached a link 100 which is connected to a slide 101 mounted upon a tie rod 16 and similar to the slide 88 previously described. The slide 101 is also provided with a stud and cam roller 102 which travels in a cam groove 103 in the stationary cylinder 104.

The grooves 90 and 103 are so related to each other that the vertical position of the spinning rolls and the pressure of the rolls upon the sleeves are coordinated with each other so that the sleeves are subjected to a spinning process and simultaneously to a drawing or ironing out process as Well;

It will be noticed also that the mechanism controlling the position ofthe spinningrolls and the mechanism controlling the pressure of the rolls are independent of each other and that each is controlled by the particular form of cam groove which causes its movement. The machine is therefore adapted to bring any desired pressure to bear upon the spinning rolls at any particular position into which the rolls may be moved. Each function of the spinning mechanism is therefore capable of being independently aswell as coordinately controlled. I

Inthe present-instance, this is taken advantage of to increase the pressure ofthe rolls directly with their downward 'movement, the cam grooves beingplotted for this Furthermore the resilient members 92, 92 r are adapted to yield slightly should the purpose, so that the joining sleeve is'held spinning rolls strike an obstruction orimperfection either in the ferrule or the bottle .neck and the rolls will ride over such an obstruction avoiding breakage and at'the same time completing a satisfactory sealing operation.

The invention is disclosed in connection with a mechanism speciallyadapted for'thesealing of caps to non-refillable bottles; but Q i it is to be understood that the invention is not restricted to this particular illustrative details of the mechanism disclosed without departing from the spirit of the invention. The spinning rolls described and shown may be replaced by non-rotary spinning tools in the nature of a simple burnisher; for the cam grooves controlling the different movements of thespinning mechanism other mechanical devices may be employed to effect the purposes of the invention; in addition to these many other changes are possible, so that the invention is not to be limited to the particular structure and the specific details herein disclosed.
