FREPERICK I. WOOD, OF OAK PARK, ILLINOIS, ASSIGNOR '10 AMERICAN CAN COMPANY, OF YORK, N. Y., CORPORATION OF NEW JERSEY.

CONTAINER-COATING MACHINE.

Application filed my 28, 1915. serial No. 30,912.

To all whom it may concern:

Be it known that I, FREDERICK P. Woo,

- a subject of the King of Great Britain, residing in Oak Park, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Container-Coating Machines, of which the following is a specification.

' This invention relates in general to coatmachines for cans, containers or other receptacles and has more particular referobject of this invention is the present invention are designed. In this such material.-

form of can one end is closed and the other end is provided with an inwardl' extending flange or ring against which 0 osures or covers may be seated. The machine hereinafter describedis adapted to prevent any break or interruption in the internal coat-. 35

ing through the trapping of air behind the flange or ring when the can is immersed horizontally in the coating bath.

. A further object of the invention is the provision of a machine of the character deair bubbles which will scribed which will prevent the formation of break the ,for

coating.

'A further object of the invention is the provision of. a machine which will automatically coat cans 'and drain the same of excess coating material without appreciable loss of A'still further the provision of a machine of the character described which will first coat the cans then drain them and after draining turn them end for end and cause any excess of material within the can to settle in and around the seam betweenthe bottom and the body of Specification of Letters Patent; Y

a machine for coating canobj'ect of the invention. is

Patented Aug. c; was.

the can to insure the provision .of a perfectly coated bottom connection.

Other objects and advantages of the invention will be apparent as it is better understood from the following description when considered'in connection with the accompanying drawin ferred embodiment t ereof.

Referring to the drawings,

illustrating a pre- Figure 1 is a side elevation of amachine embodying my-invention shown partially in section; and

'Fig. 2 is atop plan view thereof.

The machine shown on the'drawing and used for the purpose of illustrating my invention, consists of a receptacle A containing a coating bath B, a carrier 0, a can feeding mechanism D, a can delivery'device E,

- a pair of conveyors F and G and driving means H together with the other at mndant means, mechanisms and devices to be later described.

The cans 3 shown on the drawing are of paper or other fibrous material and each is provided with a bottom 4 at one end and a ring 5 at the'other, against which may be seated a suitable closure (not shown). It, is intended in the present machine to coat both the inside and outside of the cans by 1mmersion and the can bodies, after being provided with the ring and bottom just described, roll down a chute 6, one end of which is disposed at the rece tacle A; This receptacle has a' double wall and8, preferably of' metal, and mounted upon asuitable base 9, the two walls of which rovidea heating space into which a" suitab e heating fluid may be introduced through an inlet pipe 10 and taken out through an inlet pipe 11 in circulation. Theicoatmg material in. the present instance is a fluid mass B, ke t at proper fluidity by the temperature of t e receptacle and heat transmission through the inner wall 7 thereof.

The cans 3 are received from thechute 6 by the carrier C and this carrler, 1n the presentinstance, consists of apair of notched disks or plates 12, 13 mounted upon a shaft 14 which is supported in bearings 15 from the top of the receptacle. The shaft 15- carries a gear 16 meshing with a pinion 17 upon a shaft 1.8 carrying a pulley 19 driven by "a belt 20 from any suitable source of power. The shaft 14 is preferably disposed rial advantages, the form hereinbefore des scribed being merely a preferred embodiment thereo I claim:

1. A machine for coating can bodies com- -prising in combination, -a receptacle for holding a coating bath, a rotatable carrier mounted therein and provided with means for engaging the cans to hold-them against rotation independently of said carrier, and

feeding mechanism for delivering cans to said carrier, comprising an inclined chute and a movable stop havin members adapted to pass down at the trout and rear of the can next to be fed from said chute.

2. A machine for coating can bodies comrising in combination, a receptacle for holding a coating bath, a rotatable carrier mounted therein and provided with means for engaging the cans to hold them against rotation independently of said carrier, and

a hook-shaped arm for automatically delivering cans from said carrier.

3. A machine for coating can bodies comprising in combination, a bath receptacle, a carrier mounted therein and adapted to convey cans in horizontal position thereto, and a delivery mechanism, said delivery mechanism comprising means for ejecting the cans can bodies therein, a drainage conveyer,

means for guiding the dipped cans sidewise toward the drainage conveyer, means for supporting the cans at one end only while the other. end drops 'in-a direction transverse to the movement of the conveyer for witnesses.

delivering the can bodies open end downward on said conveyer, a second conveyer below the drainage conveyer, and means for arresting the open end of the can bodies while the closed end tilts over in the direction of. the movement of the conveyer on to said second conveyer. '5. The combination of a bath receptacle, a rotary carrier therein having means for can bodies with their axes horizontal an parallel with the axis of the carrier, means fordisengaging the can bodies from said carrier with thelr' axes in horizontal position, a drainage conveyer, and 'means whereby the can bodies are 'caused to roll freely after disengagement and are tilted into vertical position with their open ends downward on said drainage conveyer.

- 6, A machine for coating can bodies comprising in combination, a receptacle for a bath of coating material, a carrier for dipping can bodies therein, a conveyer for receivmg can bodies from said carrier, a blast pipe directed against the closed end of the can body and operating on the same to force excess of coating material toward the open end of said body before the can body is received on said conveyer, and means for depositing the can bodies open end dfiwnward on said conveyer.

7. A machine for coating cans, comprising,

in combination: a receptacle for holding a bath of coating glue; and a rotatable carrier mounted in said receptacle and having an arc of travel in said bath, and provided with means for engaging can bodies with their axes horizontally disposed, said engaging means acting to hold the can bodies against rotation relative to the carrier Signed in the presence of two subscrlblng FREDERICK 1?.
