.To all whom it may concern:

Be it known that I, CHARLES L. BURDICK, 4a* citizen of the United States, residin at London, in the county of Middlesex,

- improvement in Coloring-Machines, (Case f No. 4,)'0f which the following is a full, Clear,

concise, and exact description, reference being had to the accompanying drawings, forming a part of this s ecification'.

My invention re ates to painting and c oloring machinery; and its object is to provide a machine of improved construction and desi n for putting color or laze, or both, on ti es, porcelain, lass, eart enware, or other articles and whic may also be used for coloring or painting such articles as Wood blocks, cards, and the like, the object being to secure greater rapidity than has heretofore been obtained. To accomplish this, l provide a machine with means for carrying the objects to be colored into the held of sprayers, which direct their spray against the object, and l also provide means for rotating or spinning the object while in the field of the sprayers. The object to be colored may be carried through several of such sprayer-iields until the desired color or paint is ap lied thereto.

My invention will be etter understood by reference to the accompanying drawings, in which- Figure 1 shows a plan view of a machine;

Fig. 2, a vertical cross-sectional view thereof, taken on line 2 2 of Fig. 1; Fig. 3, an enlarged sectional view, taken on line2 2 of Fig. 1, of the spinning-table mechanism; Fig. 4,v a side view of trip-lever mechanism for releasing the spinning tables; and Fig. 5, a plan view of a modified construction of the machine adapted for painting or coloring wood blocks, cards, tiles, or the like.

Like characters of reference refer to like parts throughout the various figures.

A supportin -framework 1 supports a vertical shaft 2, wxich is carried in a lower stepbearing 3 and in an upper guide-bearing 4. A circular table 5 is rigidly supported from the shaft 2 in any convenient manner and is shown as being clamped to the shaft between a shoulder 6 and a threaded flange 7, engagin the threaded portion 8 of the shaft. A be t-wheel 8 is secured to the shaft at any convenient part thereof, and by means of a belt 9 the shaft, with the circular table, may

be driven from any motive source. The

ng- 5 land, have invented a certain new and luseful uniformity in the work and greatertable is provided near its periphery with an annular groove or channel 10, and a rim or liange 11 surrounds the Vperi heral edge of the table. Within this annu ar channel the spinning apparatus is placed, this apparatus consisting of a rectangular base 12, provided With a central spindle 13 anda second spin dle .14. A circular spinning table 15 is piv oted over the'spindle 13, andthe hub 16 of this spinning table is engaged by a pinion 17, pivoted on the spindle 14, this pinion having -engagement with the inner face of the iliange or rim 11. Thus upon relativel movement between the base 112 and the table 5 rotary motion will be transmitted to the spinning table 15 and to the object thereon, such as a vase 17. The hub 16, the pinion 17, and the iiange 11 may be providedwith. ear-teeth or may be provided with frictiona surfaces, being shown provided with a layer 18 of some frictional substance, which may be leather o r rubber.

'To prevent movement of the spinning-table bases at fixed positions about the machine, l provide trip-levers 1.9. These triplevers are ill-shaped and are pivoted to uprights or standards 20 20, which standards may be extensions of the legs 21 21 for supporting the machine. One limb of the levers is disposed over the rotating table and normally in the path of posts 23, extending from each of the rectangular bases 12. The other end 24 of the levers is disposed below the circular table 5 and in the path of camlugs 25, which may be secured to the under side of `thetable 5.v A spring 26 for each lever normally tends to maintain the limb 22 in the path of the posts 23 and the limb 24 in the path of the cam-lugs 25. As a base 12, carrying a spinning table, passes into position before a trip-lever it will come to rest upon the post 23vthe'reof, engaging the limb 22 of the trip-lever. The circular table 5, however, continues its motion, and this motion is transmitted., through the friction-pinion,17, to the table 15, causing rotation or spinning thereof. As a cam-lug 25 now ap- Eroaches the trip-lever it will, engage the 'mb 24 of the lever to cause oscillation of the lever to raise the locking-limb 22 from the path of the post 23, and the member 12, with its spinning table, will be released, and upon such release the base 12 will be carried with the table 5, and there being no relative movement between the two rotation of the spinning table 15 will'cease. After passage ico thereby of the cam-lug 25 the triplever Will assume its normal posltion in the path of the about table 5.

posts 23, and the next spinning apparatus will be held in position in the same manner as the s inning mechanism ust released. Any num er of trip-lever mechanisms and correspondin positions of spinning of the objects carried Iiy the tables may be provided Near each of vthese spinning positions I provide one or more sprayers 28, which may be positioned to direct their spray to any part of the object carried by the spinning tables. Some of these s rayers may be conveniently mounted on t e standards above the corresponding trip-lever mechanism, and other sprayers may be mounted v in other positions--for instance, on support- Sprayers are ing-rods 27. These sprayers may be 'of any construction, and the sprayers shown consist of a body portion 28, from which extend valve-stems 29, Which terminate in valves for controlling the outlet of the sprayer. Tanks 30, containing the coloring fluid, may be mounted on the machine in any position, and the coloring-matter maybe conducted by pipes or hose 31 to the various sprayers, While pipes or hose 32 may be connected with a source of compressed air. These 1preferably all controlled to emit spray only W en the object to be colored is in the proper position in the iield of the sprayerthat is, when the trip-levers hold the bases 12 in position and the spinning table is actuated. This control of the sprayers I accomplish automatically, and each sprayer is provided With a valve-arm 33, pivoted at one end to an extension 34 from the sprayerbody and at its other end engaging a camsurface. The lever at an intermediate point has adjustable engagement With the valvestem 29 of the sprayer, and the object of the cam is to actuate the valve-arm to cause the sprayer to emit coloring-matter only vvhen t e object to be -treated is inthe proper position. The cams for actuating the valvearms are shown in the shape of strips or Wires 34 34 laid in annular grooves 35 35, these strips or Wires being preferably tapered at their ends to allow ready engagement therewith of the endsI of the valve-arms, which are preferably rovided With cam-rollers 36, as shown. T e length of these camstri sand their position in the ygrooves are suc that the corresponding valve-lever is raised when the s inning mechanism comes into position Within the field of the sprayers and 1s released to close the s rayersas the spinning mechanism leaves tlIi) sprayers. j

The-cam strips or Wires may be sprung into the grooves, which Will securely hold them therein, or they may primarily be bent into the ropershape and secured to the surface of tfie table 5.

To prevent accumulation of coloring-mat'- e field of the jects are successively moved along' the trough,

ter which fiies from the sprayers and which is not applied to the object to be colored, I provide a housing 37 about thesprayers, surrounding each position, through which housing the vase or other object to be colored passes. These housings may be secured in any convenient manner to the machineframe, and a fan 38 may be connected with the housing for withdrawing and conveying therefrom the loose particles of coloring-mat# ter.

It will readily be seen that any number of painting positions may lbe provided about the table 5, and thus one object carried from one definite coloring operation on to another before' being finished and removed from the table. The sprayers of the different positions may also be limited to deposit their spray on different parts of the object, being, as before described, maintained a certain length of time Within each field of sprayers and caused to be rotated only when within said fields.

The form of machine just deseribed is best adapted for coloring or painting objects such as vases or the like, While in Fig. 5 I have shown a modified construction and arrangement more suitably adapted for the coloring of fiat objects, such as Wood blocks, cards, and the like. For coloring such objects a spinning table is not necessary and the different coloring effects can be readily' accomplished by a suitable disposition and direction of the spra ers. The outer rim or flange 11 may be omltted fromthis construction and the table 5, posts 39 39, against which the objects 40 to be colored are placed. Each sprayer is here also provided With a valve-arm 33, adapted to be en aged by actuatin -cams 34, so arranged t at the correspon ing sprayers are actuated only when an object to be colored passes through the coloring-field. Each set of cams is therefore placed radially opposite a corresponding position of the object on the table. I provide automatic means for collecting the colored and finished objects from the table and for conveying[ them from the machine to a receptacle. therefore provide a chute or guide-trou h 41, Whose end 42 is disposed against the ta le in a position to receive the objects thereon after having been colored. A circular slot 43 is provided in the trough through which slot may pass the posts 39, these posts serving to push the card engaged thereby along the trough, as shown, each succeeding object engaging the object last received on the trough, and thus the obfrom which they fall to a conveyer-belt 44, Which carries them to a receptacle 45. In this construction also the sprayers may be surrounded by housings connected with fans for removing the surplus coloring-matter.

I thus provide an improved machine which provided with legs or' ICO ICS
