3 claims (oi; 9H0) This. invention is a novel apparatus or machine for use in painting small objects, and. it provides mechanism wherebya'number of objects. may be rotatably mounted upon a movable carrier, which carrier when loaded with the objects can be placed upon a rotatable support, and; as the latter is rotated the objects be successively moved past-the operative point where they can be subjected to the action of the painting devices and 10 then moved on out of the way; and when all the objects have been painted the painted objects can be removed and placed to one side to permit the objects to dry, while another carrier filled with objects to be painted can be placed upon the support, sothat the painting operations may be practicallycontinuous.

The invention. further provides means whereby each of the objects to'be painted may be rotated while passing the operative point so that all parts of the object will be conveniently presented to the painting device, enabling a rapid and smooth application of paint to all surfaces of the object.

In.the. accompanying drawings is illustrated 35 one practical mechanism. embodying the invention and some. modifications, and I will describe the invention with referencetheretoto enable others to adopt and use the same; but I do not. consider the invention restricted .to the. specific constructions illustrated, and refer to the claims for the novelv features of the invention and novel combination of parts forwhich protection is desired.

showing a. modified Fig. 8 is a detail section showing another mOdification. v In the machine shown, arotatablev support 1 is attached to or supported on the upper end of a vertical shaft 1s, and is provided with a hub member 1a in'which the upper end of shaft is is splined or pinned. Hub la' rests on a bearing 11; mounted on transverse bars 2a attached to the side bars of a frame? of any suitable construction in which the mechanism may be supported; Preferably this frame forms a housing or booth,

- open at its front side for ready access to the supthe carrier loaded with port and to facilitate the placing orremoval of I the carriers hereinafter referred-to. The shaftis may be rotated by any'suitable means, being preferably driven'by an. electric motor Im at its lower end, as indicated in Figs. 1 and}. V

' The carrier 3 is preferably'zo-f approximately the same exterior diameter ,asthesupport, and adapted to be placed upon the support 1. (see, Figs.

1-3). This carrier may be made of wood for purposes of lightness or may be made of metal. if preferred. As shown it is provided with transversetie bars or spokes '3a,- andhandles 3b; by

which the carrier may be readilytransported. When .the'c'arrier is annularI preferably. provide the support 1 with segmental; blocks 1e onits upper side which are adapted toenter between the spokes 3a of the carrier and engagethe inner periphery thereof, and accurately, and fixedlyon the support 1, so that the carrier will rotate. therewith. Preferablyin the 'peripheryof the carrier is an annular channel or groove 30, and in the car'- rier adjacent the groove are a number. ofspaced thus position; the carrier I bores or holes 3d in which the shanksyor supports,

of the objects A to bepaintfed may be placed as indicated in the drawings, :In Figs. 4, '7; and 8 the objectsare shown assliders', or gliderswhich' have pins a adapted to be inserted inthe legs of furniture andthe like; and the pinscan be slipped intothe holes 3d-as indicated in Figs; ,4. and 6, the holes 3d intersecting the rear edges of -the channel 3;: so that the pins can comeinto contact with a friction member hereinafteridescribedfas the carrier is rotated; and the pins will be rotated by frictional contact with such member and rotate the objects as theypass thepainting.

On the-lower end of shaft 501 may be fastened a In Fig-'7 adisktris as the carrier is rotated, in'themanner above described, to cause the object to rotate as itp'ass'e's the-painting point. Instead of a disk a gear 5s might be used, as in Fig. 8, such gear meshing with arack 4s-on the yieldable member 4twhich otherhousing having an wise corresponds with the friction member shown inFigG."

'In'theconstruction shown in Fig. 8 the holder 5] may. carry a -head'5lc of rubber or othersuit' able material which is adapted to enter a socket in the bottom of the object to be treated. Obviously as stated the heads 5g or 576 may be shaped to engage and" hold the particular'kind of object to be painted.

In some cases it may be desirable to warm the objects or heat them priorto the painting operation, and for this purpose the support l'may be housedas indicatedias H in Figs. 1 and 2, said opening in itsfront through and carrier partially project; provided with a door D which which the support this housing being '1 can be readily opene d to permit the placingor removalof the carriers, and which maybe pro vided withjiopenings d at the points where during a 'therota'tion of the carrier thearticles would have In this way after the carrier [enough to be heatedbefore to pass through the door when the latter is closed.

andas the latter rotates an oper tor standing at the front'of the booth paints the objects, preferablyby means of a spray gun, and as the objects are rotated on their own axes as they pass the operator all points of the objects are presented to the operator for painting without his having to handle them. After all the objects on the carrier have beenpaintd, the carrier; con-- taining the painted objects can be removed and set aside with the painted objects until they have dried; and another carrier with unpainted-ob jects placedfin position onthe support, 1 and the objectspainted as described. i he time required for'painting an object with this machine, is very short and with a :sufficient 'number of carriers oneoperatorgand an assistant to load the carriers place them on the support and remove them when they are painted, can

paint a large time.
