PAINTING-MACHINE.

SPECIFICATION forming part of Letters Patent N0. 768,873, dated August 30, 1904.

Application filed February 28, 1903. Serial No. 145,481. (No model.)

To all whmn it may concern:

Be it known that I, CHARLES E. BELL, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a certain. new and useful Improvement in Painting-Machines, (Case No. 1,) of which the following isa full, clear, concise, and exact description, reference being bad to the accompanying drawings,

forming a part of this specification.

My invention relates to painting-machines, and more particularly to machines for applying and distributing paint on comparatively smallarticles of manufacture as distinguished from paintingmachines adapted to apply paint or other coloring-matter to large areas, such as the surfaces of buildings or bridges.

My invention is particularly well adapted for the application of paint or lacquer to tin cans commonly used for packing and preserving fruits, vegetables, or meats.

In general the objects of my invention are to not only apply paint to the desired objects, but also to uniformly and evenly distribute the paint over the surfaces of such articles.

IVhile my invention may be employed for many purposes, I shall describe an embodiment thereof particularly designed and intended for the application of lacquer to the ends of small cylindrical cans. While it is the purpose of my invention to provide a machine which will apply lacquer to such cans in a manner superior to that in which the same may be economically applied by hand,

it is a further object of my invention to provide a machine which will accomplish the desired result with the greatest possible rapidity. So far as the method of applying the lacquer is concerned, there are two principal steps in the complete operation. One may be described as the mere application of lacquer to the can, and the other as the uniform and even distribution of the lacquer over the surfaces to be coated. The means employed for applying the lacquer may be any wellknown device, such as a brush or sprayer or suitable roller.

The means employed in accordance with my invention for distributing the lacquer over the ends of the cans depends upon the prin- 5o ciples of centrifugal force for its operation. The cans after having been subjected to an application of lacquer by means of suitable rollers or brush mechanism are gripped within the jaws of a suitable centrifugal device, which after gripping the cans causes them to be rapidly rotated, whereby the lacquer is evenly distributed over the ends of the cans and whereby any surplus lacquer is thrown from the cans to be returned to the storagetank from which the lacquer is drawn to feed the brush mechanism.

It is found in practice that the mere application of lacquer to the ends of a can consumes very much less time than is necessary for the proper uniform and even distribution of the lacquer thereon. In any automatic machine it is desirable, if possible, that all the operations be carried out with sufficient rapidity or with sufficient duplication to accommodate the 7 highest speed which can properly be attained in carrying out the shortest operation.

In my improved painting-machine I employ means whereby a plurality of cans may be simultaneously acted upon to distribute the lacquer while the paint-applying mechanism is acting on a single can. In accordance with my invention I provide a rotary drum comprising spiders in which a plurality of centrifugal spinning devices are mounted. The cans after having lacquer applied to their ends are carried between the jaws of one of the centrifugal spinning devices, when it is firmly gripped and then moved away by the rotation of the spider as a whole. The suc- 5 ceeding can is brought between the jaws of the successive spinning device, which replaces that moved away by the rotation of the spider. During a considerable portion of the rotation of the spider each spinning device is given a 9 very rapid rotation, whereby the lacquer applied to the ends of the can gripped by the said spinning device is evenly and uniformly distributed. By thus providing a plurality of spinning devices a number of which are simultaneously operating to uniformly distribute lacquer I find that the total output of the machine may be gaged to correspond with the utmost rapidity with which the lacquer may be applied to the ends of the cans.

My invention will be understood by reference to the accompanying drawings, in which- Figure 1 is a side elevation of a machine constructed in accordance with my invention, parts being broken away to more clearly reveal the interior construction. Fig. 2 is a similar end elevation taken in the direction of the arrow 2 of Fig. 1. Fig. 3 is a central longitudinal sectional view taken on line 3 3 of Fig. 2, some parts being shown in elevation. Fig. 4 is a detail view showing the mechanism on the inside of one of the housings. Fig. 5 is a detail View of the feed-chute.

Similar characters of reference are used to designate similar parts in all of the figures.

l have shown a frame portion 10, in suitable bearings of which is mounted the main driving-shaft 11, to which the driving-wheel 12 is attached. To the upper part of the frame is bolted a housing comprising two substantially circular end portions 13 13. lVithin this housing is rotatably mounted upon a shaft 14 a drum comprising the spiders 15 and 16, each provided with bearings 17, within which are rotatably mounted the spinning-spindles 18. To the inner ends of these spindles are attached the jaws 19, which may desirably be provided with a conical flange portion 20. The spindles mounted within the spider 15 are provided with pulleys 21 21, these pulleys being engaged by a belt 22, passing about the belt-wheel 23 and a counter -shaft pulley. (Not shown.) The pulleys 21 21 are desirably splined upon the spindles 18 18 to permit a relative longitudinal movement.

As will be more fully explained, the painted cans are fed between the jaws 19, which are then brought into contact with these cans. The rotation of the spindles within the spiders causes an even distribution of the lacquer on account of the centrifugal force. The cans are carried from the feeding device during this spinning movement by the rotation of the spiders as a whole. A gear-wheel 24 is keyed to the end of the shaft 14 and is driven through an intermediate gear 25 by the gear 26, keyed to the end of the main shaft 11. It will be noticed that there are eight spinning devices mounted within the spiders 15 and 16. To correspond with this arrangement the ratio of gearing between the gear 24 and the pinion 26 is eight to one, so that eight revolutions of the main shaft 11 cause one revolution of the spiders 15 and 16. The

gears

27, 28, 29, and 30 transmit power from the shaft 14 to a shaft 31, upon which is mounted a feed-wheel 32, to the periphery of which are fastened fingers 33. The rotation of the spiders is in the direction indicated by the arrow 34, while that of the feed-wheel 32 is in the direction indicated by the arrow 35. A feed-chute 36 is provided through which cans are fed to the feed-wheel 32. As best illustrated in Fig. 5, the bottom of the feed-chute is provided at its lower end with a suitable slot 37, through which the fingers of the feed-wheel may pass to engage the can 38 at the lower end of the chute. A can picked up by afinger 33 of the feed-wheel 32 is carried from the feed-chute upwardly between a pair of guide-walls 39 39. The lacquei applying rolls 40 40 are each pirotally carried in a fork-shaped carrier-41 which in turn is rotatably mounted in the framepiece 42. This frame-piece 42 is attached to the cross-bar 43 of the frame of the machine. A spring 44 serves to press the roller inwardly toward a can passing between the guidewalls 39 39. A suitable opening is provided in each of the guide-walls, through which a roller may project. The rollers are prcferably covered with some soft spongy material, such as sheepskin from which the wool has not been removed. A feed-tank 45 is mounted near the upper part of the machine, from which the pipes 46 46 lead to the rolls 4O 40. Each of these pipes is provided with a valve 47. by means of which the supply of lacquer to the rolls maybe regulated. A can while being carried between the rolls 4() 40 by a finger 33 of the feed-wheel 32 causes the rotation of the rolls, which at the same time are pressed slightly outward by the interposed can. The surface of the roll, which is saturated with lacquer, coming in contact with the end of the can causes an application of lacquer thereto.

Mechanism to be hereinafter more fully explained is provided, whereby a descending pair of jaws 19 is brought down, one on each side of the can, which has been carried upwardly between the rolls by the feed-wheel. Upon reaching a suitable point near the top of the path of rotation of the feed-wheel these jaws come together to engage a can, which is thereafter carried away by the rotation of the spiders 15 and 16 and during such rotation is given a rapid spinning motion to distribute the lacquer over the ends of the can. It will thus be seen that the main purpose of the feedwheel 32 and its fingers is to carry the cans from the feed-chute between the lacquer-ap plying rollers 40 40 to a point at which the cans are removed from the feed-wheel by the jaws of the spinning devices.

By reference more particularly to Fig. 2 it will be seen that the outer end of each of the spindles 18 is provided with a grooved collar 48. A spring 49 is placed over each of the spindles 18 and being in compression between a collar 50, attached to the spindle and the inner side of the spider, forces the grippingjaw 19 of the associated spindle inwardly in opposition with a corresponding jaw on the spindle mounted in the other spider. A.

The

grooves in the collars on the ends of the spindles engage these segments of the circular tracks 51 51, whereby, starting from a point near the top of their path of revolution, a spindle 18 and the associated jaw 19 move downwardly in their innermost position, due to the expansion of a spring 49. Upon reach ing and engaging the inclined portion 53 of the track 51 the groove in the collar 18 serves to withdraw the jaw 19 from its innermost position against the compression of the spring Upon reaching the end 51 of the track 51 the groove of a collar passes onto the end of a narrow lever 55. The end 5a of the track 51 is placed so that the spindle may be released to engage a can which has been brought by a linger 33 to the upper point in the revolution of the feed-wheel 32. In order that the jaws maynot be too forciblysnapped together, due to the sudden expansion of the springs 19, the lever 55 is provided to let the jaws 19 down easily upon the can to be carried thereby. There is provided a cam 56, mounted upon a shaft 57, having bevel-geared connection with the main shaft 11. A roller 58 upon each of the levers 55 rides upon one of the cams 56. These cams are so shaped as to allow an inward movement of the lever 55 immediately after a grooved collar 48 has passed from the end 54 of the track 51. Thus the jaws 19 are allowed a somewhat retarded inward movement to engage the can which has been brought into proper position by the feed-wheel 32. The can being thus firmly gripped between the jaws 19, due to the compression of the springs 4:9, is carried around by the drum in the direction of the arrow 34:. The belt 22, passing from a counter-shaft pulley overhead around the idler-wheel 23, comes into contact with the pulley-wheels 21, splined on the spindles 18, during a considerable portion of the revolution of the spiders 15 and 16. Thus the spindles, having gripped between them a can, pass around in the direction of the arrow 3 1 until the associated pulley 21 is engaged by the rapidly-movingbelt 22 to cause a rapid spinning motion of the spindles and the can engaged by the jaws 19.

Since the speed of rotation of the spinning spindles is preferably quite highfor example, in the neighborhood of two thousand revolutions per minuteI have found it desirable to provide some means for preventing a slippage between the can and the grippingjaws as the speed of rotation is increased. Such means is provided by the plate 59, which is held in position by the flat elliptic springs 60 60, which exert an inward pressure upon the plate 59 when engaged by the projecting end of a collar 48. One of these plates is provided on the interior of each of the end walls 13 of the housing. The spindles pass between the plates 59 at either end of the drum upon being engaged by the belt 22 to cause a rotation thereof. Thus during the time that the spinning-spindles and an engaged can are brought up to speed there is exerted through the spindles 18 and jaws 19 upon the gripped can an additional pressure, due to the pres' sure of the elliptic springs 60 60, transmitted through the plates 59 59. The plates 59 are not extended beyond the point 61, for the reason that after the cans have been brought up to speed there is no necessity for the additional pressure between the jaws 19. A dischargechute 62 is provided, into the end of which the cans are dropped from the jaws 19 when the spindles 18 are moved outwardly on account of the engagement of the grooved collars 48 with the inclined portions 53 of the tracks 51.

It is desirable that the rotation of the spindles and cans be stopped before the cans are discharged into the chute 62. For the purpose of stopping the rotation of these spindles, therefore, I provideabrake-shoe 63, pivotally mounted on the frame of the machine at 64, a spring and adjusting mechanism 65 serving to press the brake-shoe downwardly upon a pulley 21 passing underneath. Thus after having been engaged by the belt 22 to cause a rapid rotation thereof the pulley passes under the influence of the brake-shoe 63, whereupon the spinning motion of the associated spindles is retarded and brought to a stop. Shortly after passing from the influence of the brake-shoe 63 the jaws 19 are drawn open by the'inclined portions 53 53 of the tracks 51 to discharge the can. The rapid spinning motion imparted to the can while' passing from the feed-wheel 32 to the brake shoe 63 causes the uniform and even distri bution of the lacquer, due to centrifugal force. Small holes 68 are desirably provided in the flange 20 of each of the jaws 19 to permit the escape of excess lacquer which has been applied to the ends of the can.

As a means of safety to prevent any accident due to the catching of the shoulders of the collars 4.8 on the ends of the tracks 51 I provide the inclined guide-pieces 66 66. These guide-pieces perform no useful function unless one of the springs 49 is broken or rendered defective in its operation. Similarly guide' pieces 67 67 serve to prevent a collar catching on the end of a plate 59.

Many modifications in the construction herein particularly described and illustrated will be apparent to those skilled in the art, and I I do not therefore wish to limit myself to the precise construction herein set forth; but,
