MICHAEL ASCHERL, OF CLEVELAND, OHIO.

SPRAY APPLIANCE.

Application filed July 22, 1924. Serial No. 727,502. i y

My invention pertains to a spraying `apparatus and more-particularly, as exempllfied by the drawings, to a multi-color spray device which is portable and which utlhze-s 5 compressed air not only to project a powder or fluid from a discharge nozzle, but also to constitute the motive power for intermittently moving different containers into operative position.

The object of my invention is to facihtate, expedite and cheapen the application of color coats for instance, to picture frames. A control agency and a locking device are provided for purposes which will hereinafter appear.

Adverting to the drawing:

Figure I is a vertical axial section through a spraying appliance embodying my invention.

Fi re II is a to lan view of Figure I.

F iiire III is a gln section on line III- III of Figure I.

Figure IV is a plan section on line .IV- IV of Figure I.

A round member 1, is provided with a threaded :rim 2, and centrally with a bearing 3. Detachably fitted to the member 1, is a cap 4 forming a compartment in conjunction therewith. The cap 4 is fashioned on one side with an inlet 5 and an outlet 6. A hollow structure 7 is attached to the cap 4 by means of screws 8 and has inflow and

outflow ducts

9 and 10 for the passage of compressed air controllable by means oi' a valve l1. As appears in Figure III, the duct 9 communia5 cates nearly tangentially'with the compartment.

Mounted in the bearing 3 and in another bearing 12 in the cap is a shaft 13 upon whlch is keyed for rotation within the compartment 4o a rotor 14 carrying vanes 15. Also keyed to shaft 13 is a pinion 16 which meshes with a gear 17 fixed on the lower end of a shaft 18 which projects through the cap 4 and carries a structure adapted as a clutch couple which 46 include a lower element 19 keyed to the shaft 18 and an upper bushing 2O which is slidable along the shaft 18. The top of the bushing 2O is formed with a shoulder 21 and with a key-way 22 which latter permits of effecting 50 the. desired slidable and rotatable connection 55 elements are connected as a unit as for instance by rivets 27 .n

1 Pivoted to the top ofthe cap 4 at 28 is a double armed lever one extremity being designed as a lifting finger' 29 for engagement with the disc 23. The other arm is fashioned with a slot 30 through which an'upstanding arm 31 projects.l The latter is notched at 32 to enable selective engagement with the edge of the slot 30 and hold the finger 29 and hence the quadruple unit at three desired elevations for reasons to be later explained. A spindle 33 has a screw-threadedconnection at 34 with the center of the cap 4 and carries near its lower end a support 35 having interposed between itself and the cap 4 a ball bearing 36. The support 35 is designed as an internal gear with which the gear 25 and segment 26 may bebrought into mesh. Near its top the spindle 33 carries'a spider 38 formed with four nozzles 39. The support carries four containers 40 each con-` nected by a pipe 41 with one of the nozzlesl 39. The pipes 41 and containers 40 'are in screw-threaded and therefore adjustable `con nection.

The outlet duct 10 passes throu h a handle 43 of the portable appliance an is subject to the control of a slide valve 44 beyond which the duct l0 is fitted at 45 to the top of the spindle 33 and has interposed between it and the spider 38 a ball bearing 46. The extremity 47 of the outlet duct is designed as a nozzle with which the four nozzles 39 are' adapted successively to come into right angular opposition. A brace 448 connects the doubled-back sections of the duct 10.

The periphery of the cap 4 is supplied with four e uispaced notches 49 in which' a finger 50 yie dingly supported upon the cap is adapted to slip. The finger 50 carries a roller l'which is adapted to be engaged either bv the disc 23 or the cam 24.

My spraying appliance permits of eifecting contlnuous, or intermittent containerrevolution or of cessation of revoluble movement Figure I shows the position of the controlling. parts during intermittent revoluble i actuation of the various containers. In accordance with the connections shown in Figure I, the operation is as follows Air under pressure being allowed to enter the duct 9 by opening the valve 11, impinges against the vanes 15 to rotate in turn the shaft 13, pinion 1-6, gear 17, shaft 18, bushing 20, disc 23, cam 24, full gear 25 and gear. segment 26 either of which latter may be positioned to mesh with the teeth of the internal gear 37 whereby either continuously or intermittently to rotate the support 35 and containers thereon. The segment will have the necessary number of teeth to turn the support 35 through an angle of ninety degrees for each rotation of the shaft 18 during which time the cam 24 will by engagement with the roller 51 and at the proper time intervals regularly shove the finger out of one of the notches 49 orv permit it to slip into one and arrest further rotation of the sup rt 35 while one of the nozzles 39 is op to the air discharge nozzle 47.

It it is desired continuously to rotate the containers the arm 29 is disengaged from a notch 32 and while the fin er 50 is held out of a notch 49, the arm 29 depressed to raise the full gear 25 into engagement with the internal gear 37 and to bring the disc 23 instead of the cam 24 into the plane of the roller 51, in which ition the parts may be held by causing t e next lower notch 32 to functionate.

Continued depression of the arm 29 causes the ar segment 26 to engage the shoulder 21 to lift the bushing 20 and to disengage it from the driving clutch element 19 whereupon the spraying may be effected continuously to draw upon the supply of only one container.
