I UNITED STATES PATENT OFFICE.

JOHN G. I-IODGSON, OF MAYWOOD,ILLINO1S,ASSIGNOR TO EDWIN NORTON, or SAME PLACE, AND OLIVER w. NORTON, OF CHICAGO, ILLINOIS.

CAN-TESTING MACHINE.

' SPECIFICATION forming part of Letters Patent N 0. 522,259, dated July 3, 1894.

A lication filed October 4, 1892. Renewed March 14, 1894- $erial No.503,560. (No model.)

To all whom it may concern.-

Be it known that I, JOHN G. HODGSON, a citizen of the United States, residing in Maywood, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Oan-Tes ting Machines, of which This invention relates to improvements in machines for testing cans, and more particularly to the improvements upon the can testing machine heretofore patented in Letters Patent of the United States, No. 287,048, of October 23,1883, granted to Edwin Norton and myself.

The object of the present invention is to simplify the construction of, said former machine and render its operation more certain and exact, especially in respect to the closing or sealing the opening of the can at the time it is immersed in the hot water bath. And the further object is to adapt the machine for operation upon large cans, such as ordinary five gallon square petroleum cans.

The invention consists in the novel devices and novel combinations of parts and devices herein shown and described, and more particularly pointed out in the claims.

In the accompanying drawings, which form a part of this specification, and in which the same letters of reference indicate the same or like parts throughout the several views, Figure l is a side elevation, partly in section, of a machine embodying my invention, the same however showing only one end'or half of the machine. Fig. 2 is a plan view; Fig. 3 an enlarged detail side elevation of a portion of the can carrier chain. Fig. 4. is a detail vertical sectional view of one link of-the carrier chain, and Fig. 5 an enlarged plan view showing two links of the carrier chain. Fig. 6 is a detail view illustrating the Opera tion of the inclined or approaching tracks or cams H H for opening and closing the can clamping slides, as hereinafter described.

In the drawings A represents the frame of the machine, B the tank for holdingthe hot water in which the cans are immersed during the testing operation.

B B represents steam pipe for heating the water in the tank.

C represents one of the pulleys or sprocket body to be received thereby that the pocket or cradle will fit the can body, as is clearly indicated in Fig. 3. The two side bars at d of each link, are each furnished with eyes or bearings d d to receive the hinge pivots dd. The pivot pins 01 are each provided with a flanged wheeler anti-friction roller 01 to ride upon the track F by which the carrier chain is supported and guided through and under the water tank. The tracks or rails F are,

preferably, provided with upright flanges f. The flange d on the wheel or roller d serves to keep the chain carrier in proper position between the tracks F F. The side bars d d" for each link are each provided with a horizontal web or flange d ,'which is furnished with a guide or way 61 for a laterally recip-' rocating slide G which carries the-can clamping device 9, one at each side of the chain.

The clamping devices g g each have an overhanging lip or projection g which fits over the corner x of the can X, and thus serves to hold the can in place. in its pocket or cradle when the empty can is being immersed in and carried through the bath of hot water. Each of the slides G is also furnished with a pad to press against the end of the can, the pad 9 at one end being preferably made of rubber or other like material, and adapted to close the opening wwhich is in one head of the This pad 9 is preferablyfurnished with can. a beveled inner face g so that the same may when pressure is exerted against the head of the can, as this pressure will tend to cause the head to spring inward at its center, as

indicated by the dotted lines 00 at Fig. 4t. 7

The other pad 9 which presses against the opposite end of the can where there is no opening in the head, may, preferably, be made fiat and of any suitable'yielding material gaging these rollers g on the opposite side,

serves to open the slides G G to permit the discharge of the cans from the carrier, and also to permit the cans tobe delivered into the carrier.

The pulley 0, one at each end of the tank around which the chain carrier travels, con sists of two wheels 0 0 between which the links of the chain fit or are suspended, each wheel 0 having notches c on its periphery to receive the flanged wheels (1 on the pivot pin cl.

K is a can delivery wheel furnished with pockets K to receive the cans from a chutej K and deliver them one by one into the; pockets or cradles of the endless link chain driven from the shaft 0' of the pulley O by. K0 is St curved guard fixed to the frame and evtendmeans of the intermeshing gears K ing around a portion of the circumference of the delivery wheel K for the purpose of hold-j ing the can in the pockets of such wheel as,

it revolves.

The two tracks H H which operate the slides G G for clamping the can are slightly inclined toward each other at the point where the slides are forced together to clamp the can, as is clearly shown in Figs. 2 and 6; and these tracks or ways H II incline outwardly or spread apart at the point where the slides G G are to be separated to permit the discharge of the can, as is clearly indicated in Fig. 6. As the two tracks or ways H H are thus inclined to and from each other at certain points they operate as cam tracks, or stationary cams.

I claim- 1; In a can testing machine, the combination with a tank for holding hot water, of an endless link-chain can-carrier composed of a series of solid links each comprising apair of side bars rigidly connected together and furnished with pockets or cradles for receiving the cans, and devices for clamping the cans and closing the openings therein mounted upon and carried by said links,a track for said carrier chain, and a cam or track for operating said clamping devices, substantially as specified.
