Description

W. C. BEACH PAINT SPRAYING- APPARATUS July 7, 1931.

2 Sheets-Sheet l ATTORNEY Filed July 5. 1929 y 7, 1931- i w. c. BEACH 1,812,854

PAINT SPRAYING APPARATUS Filed July 5, 1929 2 Sheets-Sheet 2 ATTORNEY Patented July 7, 1931 PATENT OFFICE WILLARD o. BEACH, or EAST ORANGE, NEW JERSEY IAINT' SPRAYING APPARATUS Application filed July 3, 1929. Seria1 No. 375,808.

This invention relates to paint spraying devices and has for an object the provision of an apparatus by which paint may be automatically sprayedevenly and rapidly upon a moving surface.

I A further object is the provision of a carriage upon which standard paint spray guns may be mounted without alteration.

A further objectis the provision of means by which the spraying action of the gun may be stopped automatically at predetermined points.

A further object is the provision of means for regulating the spraying action of the guns. i

' These and other objects are'attained bythe novel combination and arrangement of parts hereinafter described and shown 1n the accompanying drawings, constituting a ma- 1 terial part of this disclosure and in which:

Fig. 1 represents a plan view of the apparatus.

Fig. 2 represents a front elevational View of the apparatus.

Fig. 3 represents a partial rear elevational view. 1

Fig. 4 represents a perspective view of a sliding carriage having paint spraying guns mounted thereon.

Pg. 5 represents a sectional'view taken on line 5-5 of Fig. 4.

Referring to the drawings,'in Fig. 2, the apparatus is shown to include supporting frames 6 and 7, upon which are mounted plates 8, the latter supporting the shafts 9 and 10, and a track 11, upon which the triggers of the spray guns travel. a

The spray guns, of which there may be any desired number, are mounted on a carriage comprising the plate 12, to which is fixed the pair of upper bearings 13 for the shaft 9, and the lower bearings 14 for the shaft 10.

' Fixed to the plate 12 between the bearings 13 and 14, are angles 15 and 17, which cooperate with the plates 16 and 18, to clamp the spray guns 19 and 20 to the carriage.

The trigger 21 of the spray gun is provided.

at its extremity with spaced ears between which is rotatably mounted a roller 22, the latter travelling on the track 11. The trigger is pressed upwardly by contact with the track 11 to cause the gun to spray; and when the carriage reaches'either end of the track 11, the trigger falls into the cut-away portion 23 of the track, and the spraying action of the gun is stopped.

Compressed air and paint hoses 24 and 25 are led to the spray guns from a supply tank 26, and are supported above the carriage by a brace 26 extending from the frame 7 Since it is desirable that the spraying action of the guns: when mounted on the carriage be regulated, the track 11 is adjustably supported by the plates 8. Integral with plates 8 are lugs 27 and 28, upon which are mounted a screw 29, the latter passing through an aperture in the track 11.

A wing nut 30 is mounted on the screw 29 and bears against a coiled spring 31, which in turn bears against the track 11,. the latter resting upon a wing nut 32, also mounted on the screw 29. By means of this arrangement the track 11 may beraiscd or lowered in order to regulate the pressure of the track on the trigger 21, and. thus regulate the spraying action of the spray gun.

The spray guns are of a standard manually operable type in which pressure upon the trigger is necessary to cause the spraying action. When used in connection with the upparatus herein disclosed, the usual triggers of the guns are replaced by roller carrying triggers such as shown at 21 in Fig. 4.

Pivotally connected with the lug on the rear face of the plate 12 is a rod 33 which has its other end pivotally connected at 33 to a stud fixture link of a chain 34, the latter passing over sprocket wheels 35 and 86, said wheels being of equal diameter.

The sprocket wheel 36 is fixed to a shaft 37, which has also fixedthereto a pulley 38 over which passes the belt 39, the latter also passing over a pulley 4O fixed to shaft 41 which has also fixed thereto a pulley 42. A belt 43 passes over the pulley 42 and also over a pulley 44 fixed to the shaft of an electric mo-- tor 45.

In operation one or more spray guns are clamped to the carriage as shown in Figure 4 and the electric motor is started. Rotation of the sprocket wheels 36 and 35 obviously I imparts a reciprocating motion to the rod 33 and to the carriage. The triggers 21 of the spray guns ride up on the track 11 and are maintained in a position to cause the gun to spray until they reach the cutout portions 23 of the track, at which point the triggers are allowed to assume a position to stop thespraying action of a gun.- Should it be deslred to increase or decrease the spraying action of v the gun the height of the track 11 is raised or lowered by means of the wing nuts 30 and 32 to increase or decrease the pressure of the rail on the triggers 21.

From the above description it will be seen that this apparatus will have a uniform spraying action and the reciprocating motion oi the carriage will cause the spray to assume an arcuate path and'strike the surface being sprayed at an acute angle greatly simulating the manner in which paint is supplied by means of a hand brush.

Obviously any number of spray guns may be mounted upon the carriage and the apparatus may be operated at any desired speed. The surface being sprayed preferably would be mounted upon a conveyor moving at a uniform rate and with the apparatus herein presented the services of an attendant are not needed. p

The foregoing disclosure isto be regarded as descriptive and illustrative only, and not as restrictive or limitative of the invention, of which obviously an embodiment may be constructed including many modifications without departing from the general scope herein indicated and denoted in the appended claim.

Having thus described my invention, what I claim asnew and desire to secure by Letters Patent, is:

In a paint spraying apparatus, a slidably mounted carriage, apaint spray gun mounted on the carriage, a track positioned adjacent the carriage, a roller attached to the trigger of the gun and bearingon the track to cause the gun to operate, said track having depressions at each end into which the roller falls to enable the trigger to discontinue the operation of the gun, said track having an aperture at each end, threaded rods passing through the apertures, and nuts in threaded engagement with said rods, the track being supported in adjusted positions by said nuts.

This specification signed this 1st day of July, 1929.

WILLARDC. BEACH.
