CAN-LACQUERING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 487,571, dated December 6, 1892.

Application filed June 15, 1892. Serial No. 436,834. (No model.)

To all whom it may concern.-

- Be it known that I, ROBERT DENISTON HUME, a citizen of the United States, residing at Gold Beach, Curry county, State of Oregon, have invented an Improvement in Can-Lacquering Machines; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a machine which is adapted to apply lacquer to the exterior surfaces of cans containing hermetically-sealed goods, the lacquer being applied after the cans are filled and sealed for the purpose of giving a finish to them.

It consists in certain details of construction,

which will be more fully explained by reference to the accompanying drawings, in which- Figure 1 is a side elevation of the apparatus, showing a vertical section of the lacquer-trough. Fig. 2 is an enlarged section of one of the traveling chains. Fig. 3 is an enlarged transverse section of the drying-chamber and the traveling chain.

A A are two standards of suitable construction, upon which the journal-shafts of two chain-wheels B are supported, the first one being considerably lower than the second.

C is a trough containing the lacquer which is to be applied to the cans, and D is a chute through which the cans are delivered to the lower end of this trough. The lower end of the trough C is shaped approximately to the curvature of the exterior of the chain-wheel B, so that as the cans roll down the chute D they will be delivered into the curved end of the lacquer-trough, following its curvature until they arrive at the lowest point, which is approximately beneath the center of the carrying-wheels B.

E is an endless chain passing around the wheels B. This chain is composed of two sets of jointed side bars connected together by transverse pins, between which the cans are delivered from the chute D.

Power is applied from any suitable source to rotate the wheels B and cause the chain E to travel upward through the lacquer-trough C from the end which receives the cans to the delivery end. The cans lying between the connecting-pins of the chain are rolled through the lacquer and up the incline, passing out of the lacquer as they do so, and from the upper end of the lacquer-trough they are delivered upon a second carryingbelt G. This belt is composed of a pair of endless chains passing around pulleys H and traveling in an approximately-horizontal position. Below the chain is a supportingtrack I, which prevents sagging.

Between the sides of the chain are the transverse pins J, which unite the ends of each pair of links and the intermediate pins J These pins are turned with projecting flanges J, and when the cans are delivered from the first chain E they fall upon the flanges of the pins J J which thus support them, with the smallest possible points touching the freshly-lacquered surface. The ends of the pins J pass through slots in the side bars of the chain, and they are held at any point by clamping-nuts, so that they may be adjusted to suit the size of the cans which are being treated. The cans delivered upon this chain then rest upon these flanges J, and are carried by the chain through the drying-drum K, which consists of acasing surrounding the chain fora considerable distance, open at both ends to allow the chain and cans to enter and pass out. Within this casing is a coil of steam-pipe L, supplied through an inlet-pipe L and having an exhaust or discharge at the opposite end. As many coils of the pipe may be employed as would be necessary to dry the lacquer upon the cans as they passthrough the casing K, and as the chain passes out at the opposite end of the casing it carries the lacquered cans overa pipe or pipes M, having perforations made through them and being connected with any suitable blast apparatus N, through which a supply of cold air is consta'ntly forced. This air playing out through the openings in the pipes M will cool the cans, so that they are delivered in proper condition from the discharge end of the chain. The two sets of chain-pulleys B and H are driven from the same source of power by in termediate gearing upon their respective wheel-shafts.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-=- 1. An apparatus for lacquering cans, consisting of an inclined lacquercontaining trough, a chute by which the cans are delivered into thelower end of the trough, an openlinked chain passing around pulleys and dipping into the lacquer-trough, so as to receive the cans and roll them out at the upper end of the trough, a second chain adapted to receive the cans as they are discharged from the lacquer-trough, and a casing through which said chain passes, within which heat is applied to dry the lacquer, substantially as herein described.

2. An apparatus for lacquering cans, consisting of the inclined lacquer-trough, achute from which cans are delivered to the lower end thereof, an endless traveling open-linked chain passingaround supporting-pulleys and adapted to receive the cans and move them through the lacquer-trough to the discharge end, a receiving-belt consisting of endless chains having transverse pins formed with sharp-edged flanges between the sides of the chain, upon which flanges the cans are received and supported, a drying chamber through which the chain passes, whereby the lacquer is dried, and a device by which the of the inclined lacquer-containing trough,an

endless open-linked carrying-chain dipping into said trough, a chute by which the cans delivered to the lower end of the trough between the links of the chain by which they are carried to the upper and discharge end, a second beltconsisting 0f open-linked chains having transverse adjustable pins with raised flanges upon which the cans are received, a drying'chamber through which the chains and cans pass to dry thelacquer, and a cooling device consisting of perforated air-pipes anda blast apparatus arranged with relation to the traveling chain to allow the blast of cold air to be delivered upon the cans as they pass over the perforated pipes, substantially as herein described.

In witness whereof I have hereunto set my hand.

ROBERT DENISTON HUME.
