MACHINE FOR APPLYING BOTTOMS T0 CANS.

Patented Nov. 9, 1909.

Application filed February 7, 1907. Serial No. 356,293.

T 0 all whom it may concern:

Be it known that I, JAMES C. THOM, a citizen of the United States, residing at Helmetta, in the county of Middlesex and State of New Jersey, have invented new and useful Improvements in Machines for Applying Bottoms to Cans, of which the following is a specification.

This invention relates to improvements in machines for applying can bottoms to can 1 bodies, and has for its object the provision of a machine for doing this work automatic ally, expeditiously and efficiently.

To the ends stated the invention resides in a machine possessing the elements, and the several different combinations of elements and in their arrangement and mode of operation, as hereinafter described, and then pointed out in. the appended claims.

In the accompanying drawingsis illustrated a machine according to the best known embodiment of the invention, and therein Figure 1 is a front elevation, Fig. 2, a side View, Fig. 3, a top plan View, Fig. 4, a detail, Fig. 5, a partial side elevation showing a modification of the driving means,

ards

1 and 2, a suitable table or platform 3 connected to and bridging between the standards, and a pedestal 5 rising from said table or platform, the said several standards and pedestal having appropriate journals 6 for the hereinafter referred to machine shafts. i

Keyed on a shaft 7 j ournaled in hearings in the standards 1. 2, is a mandrel-carrier 8 in which are rotatably mounted radial arms 9 provided with planet-gears 10 and carrying mandrels 11. The mandrels 11 are suited to the dimensions and shape of the canbody to be bottomed. -The mandrels are provided with one element'12'of a crimper, the other element of which is to be described, and the combined elements constitute a crimper for crimping the can-bottom B on to the can-body B, and the mandrels are, preferably, also provided with one element 13 of a header which operates to form an may rest. The arms 9 are provided with collars 14 arranged thereon, removed from the end a distance corresponding to the depth of the can-body, and which collars serve as gages against which one end of the can-bodies are made to abut to accurately position them with relation to the crimper element 12, and the header element 13, when the latter is used. To permit dealing with can-bodies of different dimensions, the connection of the mandrels with the arms is detachable, a suitable connection being a screw-threaded one 18, as shown in the drawing; and'the gage-collars 14 are adjustable along the arms and may be held in any desired position of adjustment, as by means'of a binding screw 15. In this or other suitable way it is obvious that mandrels corresponding to the dimensions of can-bodies to be bottomed may be arranged on the arms and the gage-collars adjusted accordingly.

The machine shown is organized to apply the bottoms to the can-bodies and secure the same preferably by crimping, and driving mechanism, one suitable type of which is shown and will be described, is provided for rotating the mandrels continuously and revolving them intermittently, step by step, causing them periodically to come to rest at appropriate stations, for example to receive the can-bodies, and while the body-crimping and body-beading operations are going on. In accordance with this design the several mandrels, in turn, come to rest in front of a can-body-presenter 16 which is shown as an arm and which may be a delivery element of a can-making or seaming machine. lVhile at rest in this position the mandrel receives a canbody which may be moved from the arm 16 and disposed upon the mandrel, by hand or otherwise. Obviously an operative may be stationed here to place the can-bodies upon the mandrel. The mandrel moves, onequarter revolution in the illustrated machine, and the succeeding one is in position to receive a can-body, while the mandrel first mentioned, and the can-body arranged thereon, comes to rest adjacent a gravity can-bottom feeder 17 ready to take a can-bottom therefrom in a manner hereinafter referred to. When the second mandrel receives its can-body it is-advanced, as was the first, and

a third, and then a fourth mandrel assumes the can-body-receiving position. The first mandrel and its can-body provided with a bottom has in the meantime come to rest in juxtaposition to a crimper-element 34: which cooperates with the crimper-element 12 of the mandrel. The

crimper elements

12 and 34 considered broadly constitute means for securing the can closures to the can bodies, and in such of the following claims where means for securing said closures to the can bodies are referred to the combination is not to be understood as limited to crimpers as the specific means. According to the designed mode of operation the mandrels must be advanced to the several positions mentioned intermittently and come to rest in such positions to permit the crimping or crimping and beading operations to be performed, and must rotate during the crimping operation. The means by which this mode of operation is accomplished will now be described :Loosely mounted on the shaft 7 is a sun-gear 19 in mesh with the planetgears 10. This sun-gear as shown in one form of arrangement Figs. 1 to L, is connected to a sleeve 20 provided with a transmitter-gear 21 in mesh with a driver-gear 22 on a drive shaft 23. The gear 22 may receive motion in any suitable manner, manually or automatically, as for instance from a moving part of a can-body making or seaming machine, in which event it will operate the mechanism for applying and crimping the can-closures in timed relation therewith. The sleeve 20 and the gear 21 fixed thereto are loosely arranged on the shaft 7. W hen the mandrel carrier 8 is driven manually, or when timed relation to another mechanism or machine is not of importance the sleeve 20 may be connected to a drum or other motion transmitter 2 1, 5, receiving motion from any suitable source. In this way the several mandrels are constantly rotated, the means for doing so being independent of the means for intermittently revolving said mandrels.

The driving mechanism by which the periodic movement of the mandrels is caused and governed, and which is regarded and claimed as a material item of invention, (although it will be understood the invention is not restricted thereto except where it is in the claims expressly mentioned) comprises the drive shaft 23 which may be driven by hand or from any suitable source of power, a driver 25 arranged on said shaft 28 provided with an eccentric stud 26 and a radially slotted transmitter cam or wheel 27, fixedly arranged on the counter shaft 7, in the slots of which the eccentric stud successively works. The radial slots of the transmitter cam open outwardly as shown and the eccentric stud engages one of said slots in each complete rotation of the driver wheel, rotating the transmitter cam and the counter-shaft through a predetermined arc, in the illustrated example of invention a quarter rotation, to accord with the particular disposition of the mechanism shown.

Preferably for the purpose of maintaining the position of the slotted cam 27 and the elements influenced thereby in the several operative positions said cam is of a peripheral contour conforming to a retaining element which is shown formed with or connected to the driver 25. Preferably to this end the, retaining device consists of a curved segmentalrib 2S and the driven cam 27 is formed with correspondiugly shaped seats 29 which cooperate with the rel aining device when the mandrels are in their eral positions as best shown in Fig. 1. During the rotation of the driver wheel 25 the slotted corners of the driven cam 27 pass into and out of the clearance 30 between the ends of the retaining device.

The can-bottom feeder is a gravity one comprising a gravity chute 31 along which the bottoms pass, flanges toward the canbodies on the mandrels. Vithin the scope of the invention the can-botto'ins may be placed in the feeder chute by hand, or this may be done auton'iatically by suitahlemechanism. At the discharge end of the chute are jaws S2 to detain the can-bottoms successively, flanges exposed in position to be engaged and removed by the can-bodies as they sweep past, the can-closures taking over the rim or circumferential edge of the bodies and'assun'ling the appropriate closing position with relation thereto. A guide or canbottom holder is provided as an extension of the feed-chute, and extends to and in front of the position of rest of the mandrels at the crimping station, the object of which is to hold the loose can-botton'is in position on the bodies while going to the crimping station, and until the crimping operation is completed.

The crimper-element 34: which coipcrates with the crimper elements 12 of the mandrels is carried by a wheel 35 carried on a stud-shaft 3G journaled in hearings in the pedestal 5, and provided with a pinion 3T meshing with a sun-gear 38 on the countershaft. This gear 38 may he se mrate from and connected to rotate in unison with the sun-gear 19 or the latter may be a double gear as may be desired. The criniper-wheel rotates in harmony with the rotation of the mandrels carrying the can-bodies and hottoms, and associated therewith, when the mandrels are provided with beader-elcinents, is a header-element 39 for cooperation therewith.

The invention provides a machine by which bottoms may be applied to cans and secured in position with rapidity, facility, accuracy and certainty.

It is desired to emphasize that the embodil. l (l ment of invention shown in the drawing is regarded as best and is recommended; at the same time it is recognized that the invention may be realized by modifications and alter ations in detail and therefore the claim of invention is not restricted to the particular details shown, except in respect of those claims where the same are expressly mentioned; and in this connection it will be understood that cans and can-bottoms are referred to as illustrative, without intending to restrict my invenion to such use--on the contrary the invention is claimed for all the uses of which it is capable.
