COATING MACHINE.

Application filed April 14, 19245. Serial No. 23,107.`

This invention relates to coating` and moreV particularly to an apparatus employed in the application of one orl more colors. r

. Brie-fly stated, an important object of this invention is to provide simple means whereby one or vmore colored fluids may be sprayed from a single device to produce a mottled 4or variegated effect A further object ofthe invention-is to provide a Yspraying device or air brush, as the same is known, and a simple means whereby the flow of fluid through the severalV nozzles may be simultaneously controlled by means'of a single control member.

v A further object is to provide simple means whereby the spray head may be detachcd and replaced by one of a different type or style ywithout entirely dismantling` the device and without the exercise of uuusual skill. v

Also, an important aim of this inventio is to provide an apparat-us of the character described which is of highly simplified construction, durable in use and cheap to manufacture.

ther objects and advantages will be apparent during the co-urse of the following description f lIn the accompanying drawings forming a part of this application and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a plan view of the improved spray apparatus.

Figure 2 is a vertical longitudinal sec# tional view thro-ugh the same.

Figure 3 is a horizontal sectional view through the improved spray apparatus.

. Figure 4L is a front end elevation of the apparatus illustrating the spray head.

Figure 5 is a rear end elevation of the improved applicator.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 5 designates a base or body plate to which an elongated handle and housing 6 is connected by 7 in the nature of screw bolts or the like. Particular attention is directed to Figure 2 which illustrates that the top of the combined housing and handle is detachable to facilitate the original assembly of the apparatus and the periodical cleaning of the same.

A plurality of fluid conducting flexible hose sections 9 are extended through the housing 6 and extend from suitable sources of suppl-y. yIn this rconnection vit might vbe stated that the severalv hose sections 9 have connection with containers for diffe-rent colored .fluids so that the fluids are all diicharged simultaneously from the forward end of the device to produce a more or lessv mottled effect on the surface to lbe coated.

Particular attention isV directed to lthe fact that a saddle 11 is extended transversely ofthe handle and housing 6 and has its somewhat narrowed upper edge positioned for engagement with the'fflexible lhose sections 9 whereby to simultaneously cut oft the supply of different colored fluids. Tlie'saddle is provided with a pair of upwardly di? rocted attaching links y12 having connection with a springle secured as indicated at 15 to the upper side of the combined handle and protecting housing` 6. Vhen the leaf lspring let is released it swings the saddle 11 up. wardly to cut off the movement of Vthe fluid andwhen the operatordepresses the leaf spring 14 by his thumb, or otherwise, the saddlell is lowered to allow the several fluids to be discharged from the apparatus or to the surface to be coated.

The forward .ends of the hose sections 9 extend beyond the combined handle and` housing 6 and have connection with the -shanks 16 of tapered nozzles 17, the said shanks 16 being extended through the head V 18. The head 18 is in the nature of la rectangle having its front wall Vprovided with a plurality` of tapered openings 19 to receive the nozzles 17 'and the nozzles 17 may be tightened in these tapered openings by advancing the shank 16. Figure 2 plainly illustrates that the rear portions ofthe shanks 16 are somewhat large and are externally threaded as indicated at 20 for conducting pipe 25 is connected as indicated at 26 to thev air chamber 24 and this air pipe,

which is provided with a valve 27, may eX- tend from an air compressor, air tanks or the like.

It will be seen that the head 18 is detachably held in place hy fastening;` devices l30 of any type so that the head and the'noz'zle carried thereby can be quickly replaced by a head of another size, so that the device may be readily modified for use in connection with various kinds of Work. Also the front Wall of the head 18 is detachable so that access may be gained to the interior of the chamber for the purpose of detaching the nozzle 17 or for cleaning purposes.

WVith reference to the foregoing description taken in connection with the accompanying drawings, it will be seen that one or a plurality of fluids may be sprayed from a single device for applying one or a plurality of colors to a surface to be coated.

The improved spraying device may be conveniently tak-en apart for the purpose of cleaning and reassembled all Without the exercise of unusual skill.

Particular attention is directed to the fact that the flow of kthe liquid through the varioushose sections is controlled by means of a separate valve not shown so that the quantity of fluids discharged from one nozzle compared With the quantity of fluids discharged from another'nozzle can be varied by the operator.

Having thus fully described my invention what I claim as new is 1. In a spray apparatus a housing, a plurality of flexible conduits extending through said housing, a movable member in said housing andsupporting rsaid conduits therein, and manually releasable tension means on said housing and in operative connection with said movable supporting member to maintain said. conduits closed by compression between saidmember and a portion of the housing.

2. In a spray apparatus a housing, a plurality of flexibieconduits extending through said housing, means for supporting said con-` duits in said housing in clamped and compressed position against a Wall thereof, and spring means on said housing compressible to move saidconduit supportingmeans to release said conduits from clamped and compressed position.

3. In aspray. apparatus a housing, a` plurality of flexible conduits extending through said housing, a saddle in said housing and supporting said conduits, a spring clip at tached externally to said housing and manually compressible thereagainst, and links movable through said housing in connection with. .said clip and saddle whereby in normal position of said clip said conduits are compressed between said saddle and a Wall of the housing.

ln testimony whereof I ahfix my signature.
