SPECIFICATION forming part of Letters Patent No. 414,568, dated November 5, 1889.

Application filed April 29, 1889. Serial No. 308,964. (No model.)

To all whom it may concern.-

Be it known that we, ROBERT ALEXANDER PAINE and DAVID BAKER, J r., citizens of the United States, residing at Richmond, in the county of Henrico and State of Virginia, have invented certain new and useful Improvements in Cylinder Striping-Machines; and we do hereby declare the following specification, taken in connection with the accompanying drawings, which form a part thereof, to be a full, clear, and exact description of our improvements, such as Will enable others skilled in the art to which it appertains to make and use the same.

The invention has relation more particularly to a machine designed to paint broomhandles, hubs, spokes, and objects of like shape in a series of bands of. variegated colors regular or irregular in width, as desired; and to this end it consists of a series of similarly-grooved adjustable cylinders mounted upon shafts in a suitable frame and carrying cords or hands, or both, arranged according to the pattern to be painted. In connection with these cylinders adjustable color pans are used, into which the face or faces of one of the cylinders dip and so submerge the cords and hands into the coloringmatter. The cords and bands convey the coloring-matter to the object to be painted, which object rests upon the cords and bands between suitable vertical adjustable stays or guides. If an excess of the coloring-matter should adhere to the cords and bands, it is removed by a suitable scraper arranged at the top of the color -pans, bearing against the cords and bands Where they run in the grooves of the cylinders. \Vhen Worked by hand, the cylinders are rotated by the adhesion of the object to be painted to the paint-conveying belts, the obj ectbeing turned by hand. IVhen operated by power, the operation is reversed, the cylinders being rotated by suitable gearing and the object rotated by adhesion to the bands, said object being held in position by a suitable frame having friction-rollers to facili- E tate the turning of the object, or both object 1 and rotated in the same or opposite direction.

In order that the invention may be more fully understood, we will now proceed to describe the same with reference to the ac companying drawings, and then more particularly point out in the claims the novel features therein.

In said drawings, Figure-I is a side elevation of the improved machine having the side piece removed. Fig. II is a plan, the supplyrack for holding the articles to be painted being omitted. Fig. III is a view of abroomhandle painted by our improved machine. Fig. IV is a side View of the adjustable end guide. Fig. V is a side elevation of amodification of our improvement, being arranged for running by'power.

A A are side pieces, and B B cross-pieces, forming the frame of the machine.

0 O are pieces forming a rack over the machine for holding the unpainted articles.

D is a large roller or cylinder, and E F are two smaller rollers or cylinders grooved to suit the patterns and carrying cords Vi and bands V in said grooves for conveying the paint to the object being painted. The large roller D has also a series of deeper grooves K K, so arranged as to allow the faces of the roller to dipinto the paint contained in a series of color-pans L L. The sides of these color-pans fit into the deep grooves K K of this large roller between the grooved faces carrying the bands and cords. The cylinders E F are mounted in sliding blocks G G and G G, respectively, which blocks are held in place and the bands and cords held taut by means of spiral springs H H and II II, attached to said blocks, said spiral springs being regulated by set-screws I I and I I, operating on screw-threaded rods attached to the springs. These setscrcws I I rest against project-ions or seats 1 In practice we have found it necessary to provide separate adjustable rollers or cylinders for the bands and cords, for the reason that the bands and cords do not shrink alike and cylinders may be attached to the power 1 when Wet, and it would be impossible to keep both bands and cordstaut by using but one adjustable roller. The color-pans LL extend under all of the cylinders, but have a slanting partition or bottom M under the rollers E F for catching the drip paint when the scrapers are not used and it is desired to apply a heavy coat of paint to the article. These color-pans (which are of the number and sizes to'suit the bands and pattern) rest on an adjustable platform N. This platform N is supported when not in use upon a second stationary platform N, forming part of the frame. four hinged blocks or links O, &c., which links limit the movement of the platform N and bring the colorpans L into position under the rollers when the machine is to be used. These links 0 O, &c., are so arranged that when the platform N is in its raised position, the upper hinged points are past the perpendicularlines from the lower'hing'ed pointa'thus forming a lock to hold said platform in the desired position to lessen the liability of its falling to its lower position.

L is a scraper attached to the edge of the pan- 'L' for removing from the bands and cords any, superfluous paint,which would otherwise spoil the well-defined lines of the striped article. This scraper may have projections extendingjinto the'ban'd andcord grooves of the f. large. roller D, though it will usually answer the purpose to have a scraper with a straight scraping-surface, as the bands and cords practically fillthe grooves in the roll and come flush with itsperiphery. Each of the adjustable cylinders may have scrapers bearing in the grooves on their faces by attaching the scrapers to a rod supported by a hinge at each end attached to the sliding blocks carrying the cylinder, so that the relativep'osition of the scrapers with reference to the cylinder will be preserved no matter vwh'atth'e position of the cylinder.

P P are vertical guides on side pieces A'A forconfining and keeping the article X to be painted at right angles to the painting cords The guides P P areadjustable, having at their lower ends, arms extending at' and bands.

right angles,'-in which arms there are slots,

which permit them to straddle guides P and set-screws B. These set-screws R are for ad- ;justingthe guides P, so as to allow for a small orlarge article to be placed between thetwo guides, the guides P P being simply driven into the frame.

In Fi'gJIV we have shown an adjustable end guide for the article X being painted. It con-- sists of stationary part S, attached to side piece A'of the 'frame and held secure by a bracket, and sliding support S, having at its oute1"end"t-"ertical end guide T, against which the end 'of the article X bears. This guide is regulated the same as vertical guide P by meansof a slot S and a set-screw U.

In operating the machine the article X to The two platforms are connected by In Fig. V is shown a modification of our improved striping-machine adapted to be run by power. This modification is of the same general construction as the hand-power machine, the principal difference being in the addition of a device for holding the article ,while being painted. Two side pieces 2 2 are pivoted on each side of the machine at 1', and these two side pieces are joined at the end nearest "the operator by'a cross-piece 3,'whic1r serves as a handle for depressing the holder. On each ofthe side pieces 2, at the proper distance from the cross-piece 3, is secured-a block 4, in which block two anti-frictionrollers 5 5. have their bearings. This holder is held normally in a raised position by spiral springs 6, connecting the blocks 4 with the piecesC of the supply-rack. In this form of the machine the end guideT is also formed on one of the blocks 4E and can be made ad j ustable, as has already been described. The machine is run by power applied to the bandwheel Z on the shaft of roller D, as shown in Fig. II. p v

The operation of the modification 'is'as fol-' lows: An article X is placed upon the side pieces '2 of the holder directly under the antifriction rollers 5 of blocks 4 with its end against the end guide T. The operator then depresses'the holder until the side pieces'2 7 come below the plane of the painting bands and belts, which will bring the article X in contact with and resting on the bands and" cords, and held in place by means of the antifriction rollers 5, which rollers revolveand lessen the friction of the revolving object.

The moving cords and bands, as has before;

been explained, bring the paint from the color-pans and deposit it on the revolving object X. As soon as the-article X' is painted the handle 3 is released and the holder carrying the article returns'to its normal position by the reaction of the spiral spring '6, when the article can be replaced by an unpainted I one and the operation repeated.

Our improvement is more especially adapted to striping regular cylindrical objects,- such as broom-handles; but'it may 'be'ar ranged to paint" irregular objectsh'aving cross-sections at diiferentpoints of d'iiferent" diameters or objects of polygonal cross sec tion. striped, some ofthe cords and'ban'ds' are drawn tighter than others to allow for-their regularities, or the longitudinal contour of VVhen such irregular articles are to be the cylinders may be of a pattern to correspond with the longitudinal contour of the object to be striped.

By the use of cords and bands narrow an d broad stripes can be painted on the object at the same operation, and when it is desired to put on stripes of one color over those of another color and of different widths and patterns it can be accomplished by two operations using different sets of rollers of different patterns for each operation. There can be as many sets of rollers as desired, each set being of a different pattern. The small cylinders E F maybe substituted by a series of separate pulleys, one for each cord and band, having separate adjustable bearingblocks, springs, and screws arranged to be transposable. The vertical guides P P may be so arranged that the article being painted will cross the painting bands and cords at an angle less than a right angle, and by this arrangement spiral stripes will be painted upon the article, the action of the bands and cords at such an angle tending to shift the article sidewise from the end guide at the same time it rotates, and thus stripe it for a part or the whole of its length, as desired.

Having thus fully described our invention, the following is what we claim as new therein and desire to secure by Letters Patent:
