- In the drawing, A represents the frame of Patented Jan. 9,1912;

the machine, B the sprayheads or spraying devices, C the cap magazines or hoppers, D the reciprocating cap feeders, E the vertically movable can cap lifters, F the rotating can cap holders, G the intermittently rotating carriers or spiders upon which the rotatable cap holders. F are journaled or mounted, H the devices for rotating the cap holders, K the strippers or ejecting devices for removing the freshly coated caps from the holders, K the connecting chute for delivering the freshly coated caps to the drier, M the drier, M the conveyer of the drier, N the supply,ta'nk for-the liquid lacquer or coating material 1 and P the valves or devices for automatically regulat-in and controlling the amount of liquid acquer or coating material sprayed upon each can cap.

In the drawing I have shown the preferred construction of. each of the principal parts or devices which are combined together to embody my invention in an automatic machine. Each of the spray heads or spraying devices B consists essentially of a liquid chamber 6 formed by a pipe or casing 6 an air chamber 1) formed by a pipe or casing b, a plurality of upright or vertically disposed liquid nozzles or nipples 6*, preferably three in number, and a corresponding series or plurality of horizontally disposed air-blast nozzles b arran ed substantially at right angles to the liquid nozzles.

The liquid chamber pipe or casing b has a contracted overflow or discharge so that the liquid lacquer or coating material may constantly fill the same and thus be maintained at a constant level in respect to the lower ends of the liquid'nozzles b. The liquid lacquer or coating material flows from the .supply tank N into the liquid chamber 1) pipe I) and overflows from said l1qu1d chamber I) through the overflow pipe 6 into a drip which it is pumped back into the supply tank N through the return pipe N by a pump N". Preferably a single liquid cham ber casing or pipe I) may be employed for each group of liquid nozzles or spray heads. A separate air chamber casing 6", however,

through a supply tank N from is preferably employed for each group &

v by branch pipes b", each of which is furnlshed with a pressure equalizer enlargement or couplin b and with a valve or pressure controlling device Pi Each of the can cap magazines or hoppers C preferably consists of an open bottom cylinder conforming in mterior diameter to the exterior diameter' of the can caps X, which are placed in the magazine with their outer faces uppermost so that the inner face of each cap which is to receive the lacquer or protective coating will be lowermost.

The can cap feeders D each preferably consists of a reciprocating slide, having a lip or shoulder d, adapted to engage the lowermost cap only in the magazine C and slide it forward over thecap lifter E. The cap feeder D reciprocates back and forth on a suitable guideD on the stationary frame of the machine, and is preferably operated by a cam r on the cam shaft R through the connecting link (5 lever d and connecting linkd a. Each of the cap lifters E preferably consists of a vertically reciprocating head i which is moved up and down by means of a cam R on the cam shaft R, which engages bar E on the stem E of the cap lifter E. The cap lifter E serves to lift or raise each can ca upward so that it will beproperly graspe by the rotatable cap holder F- on the carrier G when the feeder D moves the cap X over the lifter E; l

Each of the rotatable can cap holders F preferably consists of a permanent electromagnet secured in a rotatable head F, the

shaft or spindle f of which is journaled in the arm 9 of the carrier or spider G, and is furnished with a bevel friction gear or wheel f adapted to engage a suitable friction wheel or device H for rotating the holder and the cap when the carrier G moves the holder F and can cap thereon into cooperative relation with the vice or headB.

Each of the carriers or spiders G is preferably furnished with four arms g, and thus carries four of the rotatable holders F so that the several holders F on each carrier or spider G will have their axes at right angles to each other, and so that one holder F may be in an upright position suitable for receiving a cap from the lifterE while another holder F will have its axis horiing the cap thereon to the spray head B and rotating it in a vertical plane. riers or spiders G are preferably four'in number, corresponding with-the number of the spray heads B and they are all mounted upon or secured to the same operating shaft G which is intermittently turned by any suitable operating mechanism, the same I head F spraying dezontal and in proper position for present- The cargaging preferably consisting in a crank arm 1' on" erating mechanism of the carriers G to bring the holders F accurately into register with the cap lifter E and spraying head B;

Each of the devices H for automatically rotating the cap holders F preferably consists of a conical or friction gear or wheel secured to a shaft H and arranged in cooperative relation to the friction gear or wheel f on the spindle of the cap holder when the carrier G brings each cap holder F into position for cooperation with the spray head B. The shaft H of the cap holder rotating devices H is preferably continuously rotated by means of a pulley h on said shaft H and a belt 72, and pulley h on the driving shaft S. v

The strippers or ejecting devices K for stripping or discharging the freshly coated caps X from the magnetic cap holders F as the carrier G rotates, preferably consist of curved fingers secured to or formed integral with the connecting chute K and projecting, from the upper edge thereof and adapted to fit astride the cap holders F and engage the outer edges of the can caps X. The connectin chute K and strippers K are so arrange and combined with the carrier G and cap holders F that thecaps as they are freed from the holders slide down the connecting chute with their freshly coated faces uppermost.

The drier M referably consists of a long horizontal heating chamber furnished with gas burners or other heaters-m and having atop plate m along-which the coated caps are conveyed by a flexible or endless chain conveyer M traveling on pulleys or sprocket wheels M the links of the chain being furnished with cross bars m adapted to engage the can caps and shove them along the heated top plate of the drier. The connecting chute K is arranged at an acuteangle to the top plate and conveyer of the drier so that the freshly coated caps will the same without danger slide directly onto of being turned over. The conveyer M is preferably intermittently operated by a step by step movement by means of a crank arm m on the shaft S through a connecting linkm, pawl lever wa having pawls 'm -en- I a ratchet m" ofi the shaft m. of one of the conveyer pulleys M Each of the va ves or devices P for automatically regulating and controlling the amount of liquid lacquer or coating material sprayed upon the mner face ofeach can cap, 1s preferably automatically operated I30 cap feeder, a can cap lifter, a series of magoverflowing li uid lacquer is returne the supply tan N is preferably operated by means of an eccentric N on the shaft S and which is connected by a link N with the iston' rod N ofthe um T e li uid supply ta-n N is preferably furnishe with an agitator or stlrring device T which may preferably be operated by a connection T from the piston of the P P- a 1.
