Specification forming part of Letters Patent No. 199,623, dated January 29, 1878;` application led 'Mari-.1129, 1877.

V.To all whom it may concern:

. ing Barrels; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to devices for painting barrels; 'the revolving barrel in contact with brushes andconsistsA inchucks for receiving and mechanism -for bearing the barrell away,

substantially as hereinafter set forth and claimed. In the drawings, Figure l isA a plan view; Fig. 2, a side elevation on the side where the power is applied.k Fig. 3 is an fend elevation adjacent to the conveyer. Fig. L is a side elevation on the side opposite :the power. 5 is alongitudinal central section, by a vertical plane, containing the aXisvof the barrel; Fig. 6, a central cross section, by a vertical plane perpendicular to the aXis of the barrel; and Fig.` 7, a separate view of a chuck, which is a variation of my invention. A

.lheV objectof this invention is to paint the @a barrels both upon the body and end, andperform the operation readily and well.`

A is a barrel -way, upon which the barrels are received. B is the barrel that is being operated upon. C are the paint-brush rollers. Clare the brushes upon the said rollers. C2 are` stops, so located with respect to the rollers that at the time when the barrel comes in upon the rollers these stops will serve to 'center the barrel in proper position to, be clamped by th'echucks.l D D1 are the chucks. These chucks are provided with gearteeth ,or co'gs d d', and they, in turn, 'mesh with pinions D2 4on thesha'ft E.A Y I. F are 'frames which surround the movable chucks. vThe frames F are made to `slide in the main frame of the machine by means of guides f', in any suitable manner. The frames F also bear the paint-troughs F andthe paintbrushes G, which serve to paint the ends of 'or out of the barrel. 'Theframes F are likewise connected, by levers H, with the shaftl, and at the pointsv where they embrace the shaft I 'they are screw-threaded to fit upon the kright and left hand screws on the said shaft. The frames F likewise kcarry with them the movable chucks D D1, and the cogs are sufficiently broad to remain in gear with thepinions l)2 as the frames F are moved "in and out bythe levers H as the shaft I is turned. y

I' is a pulley, attached to suitable shafting, which will enable it to be thrown readily in gear and reversed in its motion, at pleasure. (Said contrivance is not shown, but is too well known to nee-d description, and forms no part of my invention.) y

The object of the pulley l' isA that, when the barrelis in proper position to be chucked, this pulley Iv is thrown into gear, and, being rigidly connected to the shaft I, it turns the shaft, which, by its right and left hand screws, drives the tops of the levers H apart, and they, turning upon the pivots h, force lthe chucks together and clamp the barrel in place. 4When the barrel isproperly chucked the pulley I is thrown out of gear until the bar- .rel ispainted. The pulley I is then given a 'reverse motion, which releases' the barrel, and the' chucks are in position to receive the next.

E is the drive-shaft. It has a loosepulley, J, which connects with the driving mechanism. J is a clutch, and is provided with clutchteeth jl, corresponding `to the small clutchteethj on vthe driving-pulley J. The clutch J slides on a feather, jl, on the shaft E.

A lever, k, serves to throw the clutch Jiin or out of gear with the pulley J,"`and,f of course,iwhen in gear the pulley J causes the shaftE to revolv On the shaft E, and loosely connected therewith by feathers, so as to slide thereon, are worm-gears L L'. When the shaft E' is revolved, these worm-gears likewise revolve. Theworm-gears L mesh with pinions g on the topslof the shafts of the upright brushes G, and bevelgears at thebottoms of these 'upright shafts mesh into correspondingbevelgears in the horizontal brushes G', and 'impart'revolution to them also.

giving both the'brushes motion in the same direction. This, of course, might be effected by a belt passing over pulleys l?, instead of by an intermediate gear mechanism shown.

Y The lever K has a couple of grooves, lo k1,

upon its under surface, the object being as follows: A projecting pin, k2, on top of theV lpinion m passes around through this groove,

k, and in passing farther around passes into the groove k1, and coming to the end of that groove it throws vthe lever K outward suticiently far to release the clutch J' from the pulley J, thus stopping the motion of the shaft E, and consequently stopping the revolution ofthe barrel and the motion of the paint-brushes. The gearing is so arranged that when the pulley J is thrown out of gear the barrel shall have been revolved a sufcient number of times to become thoroughly painted, andthe brushes G shall stop with the stops (l2 'in proper position for centering the next barrel, and throw all the brushes off from the barrel. Y

. Q is aleVer, poised upon the shaft E, or

upon some other suitable pivot. At the farther end of this lever is a friction-clutch, Q1, which clutch is .arranged to be opened by the upward motion of a lever, Q2. When the lever Q is raised the clutch Q1 comes down and clutches the cross-bar It. This cross-bar bears the stops Sat its ends. The object of these stops is to drop down in front of the next barrel, to prevent its rolling into themachine until the first barrel has been painted and discharged. At the other end of the -lever Q are attached the stops S and arms s'.

These stops serve also to assist in centering the barrel.

When it is desired to release the barrel from the machine, the chucks are opened to loosen the barrel. The lever Q is then raised, and thus lifting the stops S' away from the barrel, it rolls out -by its owngravity. The lever Q is then pressed downward. The clutch Q1 thus raises cross-bar It, with the stops S, from in front of the next barrel. The next barrel then rolls into the machine, and as it rolls in it strikes the lever Q2, causing it to releasey the clutch Q1, and permitting the stclips S to fall down infront of the next barre I T is an elevator or conveyer, which receives the barrel B as it rolls from the machine and bears it away, and supports it until it has been partially dried by a current of warm or cold air, or. in any suitable way.

W is a paint-trough, which supplies the largepaint-rollers. W' is a scraper at y.the side, which removes vthe surplus 4paintbefore the brush comes in contact with' the barrel; and the brushes are so arranged that one will deliver the paint while the other will remove the surplus; and in the same way with the brushes that paint the ends of the barrel-fthe horizontal ones deliver the paint and the vertical ones remove the surplus; and similar scrapers may be provided at the side troughs.

Instead "of employing the movable chucks D, as shown, all solid or in a single piece, the same may be formed of three or more parts, as shown in Fig. 7, wherein V is a rubber 0r other spring, located between the chuckingpiece and that portion bearing the gear or oogs.

l. A barrel-painting machine, consisting of movable chucks for clamping the k.ends of the barrel, in combination with mechanism, substantially as described, for revolving the barrel about its axis, and brushes for delivering paint to the surface of the barrel as it is revolved, substantially as and for the purposes described.

2. In a barrel-paintingmachine, the combination ofthe movable chucks for chucking the ends of the barrel, mechanism, substantially as described, for revolving the Y same aboutv its axis, brushes for delivering paint to the surface of the barrel, and automatic mechanism for stopping the barrel when properly painted,` substantially as and for the purposes described.
