LACQUERING-MACHINE.

Specification of Letters Patent. Patented J 21 1921.

Application filed December 1, 1919." Serial No. 341,738.

To all whom it'may concern:

Be it known that I, Snmn E. WALKER, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Improvement in Lacquering-Machines, of which the following is a specification, reference being had to the accompanyin drawings.

y invention relates to a class of devices for passing objects through lacquering fluid.

The object of my invention is to provide a device wherein a continuous line of cans may be received, successively passed through a tank containing lacquering fluid, removed therefrom and conveyed along mechanism arranged to dry the fluid on the cans and thence deposited as desired. These objects, as well as other advantages, I attain by the construction, combination and arrangement of parts illustrated in the accompanying drawings which form a part hereof.

Figure I is a plan view with intermediate parts broken away.

Fig. II is a side elevation with parts broken away.

Fig. III is a cross-section on the line TIL-III in Fig. II.

Fig. IV is a cross-section on the line IV-IV in F ig; II.

Like characters refer to like parts infthe views.- j v A supporting frame 5 of desired form is provided. In one end of the frame a tank 6,-preferably of semi-circular form, is secured. At one side of the tanka reservoir 7 is secured with a discharge pipe 8 extend,

ing from the reservoir bottom into the tank at a desired height. A valve 9 is placed in the pipe. The reservoir has a mouth 10 in its upper .end with a cap. 11 to close it, and agage12 alongside the reservoir. A shaft 13 extends transversely over the tank and is pivotally mounted in. bearingsin the opposing sideS. Of the frame 5. Upon the shaft 13 a vertical wheel 14 is rigidly secured,

positioned within the tank and in close proximity to the-bottom thereof. The wheel 14; has a series of transverse pockets, with,

shoulders at each end thereofpositioned in k a miannerjto engage the ends of objects in the pockets and prevent them from coming intocontact with the ends of the tank when thewheel is rotatingtherein. On one end of the shaft 13 a worm gear 16 is rigidly secured. A receiving chute 17 extends from a ceiving chute and in relation to the wheel.

carrier frame 19 is erected upon the frame 5 and extends from the discharge chute 18 to the opposite end of the frame 5. On the frame .19 a longitudinal track 20 1s placed. At the ends of the track transverse shafts 21-22 are pivotally mounted, andprovided with rigid sprockets 2323. Chains 24 extend longitudinally over. the respectlve opposing sprockets. Transverse rollers 25 extend between the chains and the ends thereof'are pivotally mounted in the chains. Shoulders 26 are formed on the rollers adjacent to the chain bearings, which shoulders furnish the roller tread for the tracks 20 along which they travel and also are supports to engage the cans hereafter referred to. A worm gear 27 is rigidly secured on one end of the shaft 22.- A drive shaft 28 is rotatably mountedlongitudinally of and along the side of the frame 5. The shaft 28 has a pulley 29 on one end, through which power may be transmitted to the shaft, and worms 30-30 near the ends of the shaft, positioned to engage the worm gears 16 and 27 1 respectively, to transmit power to the mechanisms in the frames. From the outer end of thetrack 19 a discharge chute 31 extends to a desired place. Along each side of the carrier frame 19, at a desired height therefrom, pipes 32 are secured upon supports 33which are attached to the frame 5. The pipes have "inwardly extending deflectors 34 secured tothem and the pipes .have orifices along them within the deflectors. A pipe 35 extends from a j the discharge chute 3 1. 1 The end rim or bead only, of the cans 36, engages the shouL. 6- M It will now be seen thatwhenl cans have been filled with. desired material andpre.

pared for the market, my device supplies an economical and automatic meansfor-lac-W quering the oans, whichisdesired .for reapreventing it from being carried forward upon the carrier frame to soil or interfere withfree movement of the carrier mechanism. It also allows delivery of a can with a reasonably proper coating of lacquer thereon, hence a better 'finished product. Only the beads or rims of the cans then rest upon the shoulders of the rollers. These shoulders may have flanges or grooves to prevent the endwise movement of the cans.

With this arrangement the cans do not otherwise engage any parts of the carrier mechanism and are rotated by the rollers as they progress. The tank is kept automatically filled to a desired height, as the feed pipe admits air and a new supply of fluid flows into the tank whenever the mouth.

of the pipe is above the fluid. The operation of the reservoir is upon a vacuum principle. It will also be seen that as the cans rotate on the carrier, all surfaces are brought under the pneumatic mechanism which discharges air upon the cans so that the lacquer thereon is practically dry when the cans are delivered upon the chute 31. The carrier is shown at an inclined angle, and this is so'arranged in order to bring the receiving end low enough to be in proper relative position to the wheel 14 and chute 18. The sprocket at that end is also necessarily of a diameter adapting it to occupy its position. Furthermore, the driving gear requiring a larger diameter and being on the same shaftwith the chain sprockets, the shaft must be high enough to allow this gear to engage'the worm 30 The driving mecha-' nism is arranged todrive the lacquering means and the carrier means from one'transmission shaft, but the arrangement thereof may be varied without departing from the principle of my invention.

In a lacquering device, of a tank of semi-circular form adapted to retain liquid at a desired depth therein, and a wheel rotatably mounted above the tank I and extending downwardly into liquid when placed therein, said wheel having a series of outwardly opening, transverse pockets with end shoulders in each, the same being arranged, to receive objects over one side of the tank, allow them to be passed downwardly through liquid in the tank out of engagement with its ends, to thereafter elethe, combinatidn 1 vate them out of the liquid and discharge them over the opposite side of the tank, during the rotation of said wheel.

2; In a lacquering device, the combination of a tank of semi-circular form adapted to retain liquid at a desired depth therein, a wheel rotatably mounted above the tank and extending downwardly into liquid when placed therein, sa'id wheel having a series of outwardly opening, transverse pockets with end shoulders in each, the same being arranged, to receive objects over one side of the tank, allow them to be passed downwardly through liquid in the tank out of engagement with its ends, to thereafter ele-- vate them out of the liquid and discharge them over the opposite side of the tank, during the rotation of said wheel, and mechanism positioned near said tank, arranged to allow a gravity discharge of liquid therefrom into the tank and to maintain therein continuously a predetermined quantity of liquid.

3. In a lacquering device, the combination of a carrier frame having a track, carrier chains havingtransverse rollers pivoted in the chains, said rollers having shoulders near their ends arranged to travel upon the track and to support objects in a manner to retain them out of engagement with any other part of the carrier mechanism, also to rotate the objects while in transit on the carrier.
