CAN-CLOSING MACHINE.

Specification of Letters Patent.

Patented July 14, 1914.

Application filed April 26, 1911. Serial No. 623,513.

To all 1 711 it m ('j/ comm-n Be it known that we. JESSE E. Animals and Ivan F. have, citizens of the United States, residing at Canonsbur in the county of lVashington, State of Pennsylvania, and Syracuse, Onondaga county, New York, respectively, have invented certain new and useful Improvements in Can-Closing Machines, of which the following is a description, reference being had to the accompanying drawing, and to the letters and figures of reference marked thereon.

The invention relates to new and useful improvements in an closing machines, that is, machines for double-seaming an end or a cover onto a filled can.

An object of the invention is to provide means which may be manually operated for placing the covers underneath the seaming head, and between the rotary chuck and the can body.

A further object of the invention is to provide means for centering the can cover underneath the seaming head and over the can body and for centering the can body relatively to the seaming head, and round u the same for the cover.

A still further ob 'ect of the invention is to provide means for placing covers under the seaming head; centering the same relative to the seaming head and supporting said cover temporarily; centering a can body underneath the cover and lowering the cover onto the can body and holding the same on the can body until secured thereto by the seaming roll. These and other objects obvious, and will in part more fully described. a

In the drawings which show by way of will in part be be hereinafter illustration one embodiment of the inventhrough the cover feed, showingthe plunger for separating the cover from the stack; Fig. 5 is a side view of the parts shown in Fig. 3; Fig. (l is a sectional view showing a can body; acover supported above the same I and the seaming head beforcbrought into engagement with the cover; Fig.7 isa similar view, showing the cover seated in the can body by the seating pad; Fig. 8 is a similar view, showing the final operation of the seaming rolls; and Fig. 9 is a similar view showing the can closed and the parts returned to normal position for discharging the cans.

frame 1 is provided on which is mounted a main shaft 2, which may be driven in any desired way. A countershaft 3 is operated from the main shaft through a belt councction 4. The seaming head 5 is carried by a vertical shaft 6, which is mounted in

bearings

7, 7, supported by the frame 1. The shaft 6 carrying the seaming head is rotated through the gear connection 8 with the countershaft. 3.

The seaming head includes an inner and outer sleeve 9 and 10, see Fig. 6. Mounted on the sleeve 10 is a curling roll 11 and a flattening roll 12, for performing the usual nccting a can end or cover to a can body by a rolled double seam. These seaming rolls are carried by levers 13, which are operated by cams on the sleeve 9, in the usual well known manner.

and the sleeveis free to chuck. Located centrally of the chuck and seaming head is a seating pad 15, which is carried by a stem 16 extending upwardly through the shaft (5, which is hollow, and said stem atits upper end carries acollar 17, which is connected to a lever 18 operated from a cam on a cross shaft 19, which may be operated in any desired way from the counter-shaft 3. The shaft 6 is moved up and down in order to bring the seaming head into contact. with the cover, and also in order to bring the seaming rolls into contact with the edge of the cover by a crank lever" 20, which is operated through the arm 21 which carries a roller running in a cam groove 22 in a disk on the shaft 19.

Underneath the seaming head is a support 23, on which the filled cans to be closed or to have covers attached thereto, may rest and move. This support 23 is adjust ably carried by the frame 1., and may be moved up and down by a screw 24, so as to position the support for different sized first and second seaming operations for con- A chuck 1-1 is mounted on the sleeve 10,

rotate about said bell In carrying out the invention, a suitable mosses carrying the seaming head, so as to move the plate out of the wa y of theseaming rolls which are brought first one and then the other into contact with the flange on the can cover and can body to form a double seam.

After the double seam is completed, the

seaming head will move upward and release the cam The plate 31 Wlll also move upward with the seaming head and the can cover which is now smallerin diameter than before it was attached to the can body, may move downward through the opening 38 in the supporting plate 31, and the seaming head and centering device will thereby be entirely released from the can body, so that it may be ejected from the machine.

It will thus be seen that by the above mechanism, the can covers areearried by mechanical means underneath the seaming head and centered relative thereto. The covers are also temporarily supported until a can body is brought underneath the cover. Furthermore, when the parts are in proper position and the seaming head descends to close the can, the can body will be centered, the cover placed thereon and seated in the can body,-and then the cover secured to the can body by a double seam.

It is obvious that minor changes in the details of construction may be made without departing from the spirit of the invention as set forth in the appended claims.
