BY wah/@WM ATTORNEYS ovEnrmAD SYSTEM FoRSPRAY -PAINr-ING ACharles iE. Martindale, lil/oodlami, Calif. Appncaaen rebiafy 2'6, 1954, serial No. y112,735
s claims. (ci. 299-86) This invention relates to spray-painting equipment or systems for cars or other portable devices which need painting and which can be removably Yplaced in a spray booth; the present application being aA continuation-.in-part of my now abandoned application, 'Serial No. 332,489, tiled January 2l, 1953.
The principal object of my invention is to provide a painting system which includes an overhead 'swingable boom from which the supply of paint and the spray hoses are supported, and which boom is arranged so that, with a relatively short hose unit, a car may be completely spray painted in an ehcient manner'and with a minimum of physical effort and time on the part of the operator.
An objectionable feature of previous spray-painting equipment, namely, a longstretch of hoor-supported hose which must be dragged around and which tends to become entangled with the ywheels of the car or other object, is, therefore, eliminated. j
Another object of the invention is to mount the paint containing pot on the swinging boom in removable association therewith, and so that said pot, when so mount ed, is connected to a source of compressed air as well as to the hose unit which carriesv the spray gun. In this manner, the need of a paint cup attached directly 'to the gun, and whose Weight is carried by the operator,
with resultant `fatigue and possible loss of control, is avoided. o
Also, a much larger supply of paint may thus be carried without having to. stop and refill the pot and without any added weight being placed on the operator, so that a complete spray-painting job may be performed without any stops being necessary for paint-supply replenishlng.
It has been found that heated paint provides an easier, faster,l and more trouble-free means of spray application than was had with cold paint.
A further object of the invention, therefore, is to provide a paint pot which is arranged to be heated and which is so thoroughly insulated that once heated, it will retain its heat for a suiicient time to enable a complete spray-painting operation to be carried out without reheating of the paint being necessary and so that no hot surface is exposed within the spray booth.
Such heating is accomplished by electrical means, and since it would be dangerous--because of possible sparks and the volatile nature of the paint fumes-to thus heat the pot within the necessarily vclosed spray booth, it is another object of the invention to provide means for supplying heat to the paint pot from a point outside the spray booth while providing means on the pot for both detachably connecting the pot to a Source of heat and subsequently to the boom in supported relation therewith.
Still another object of the invention is to provide a spray-painting system which is practical, reliable, and durable, and one which is exceedingly effective for the purpose tor which it is designed.
These objects are accomplished by means of such structure and relative arrangement of parts as will fuily api nited States Patent i vk..
Vce
2 pear Vby a perusal of the following specification and claims.`
VIn the drawings: y
Fig. 1 is a side elevation of the improved equipment of the system, as mounted in a spray booth and in loperation.
Fig. 2 is an enlarged end elevation of "the paintplot and its boom-mounting connection, taken substantially on line 2.--2 of Fig. 1. Y
Fig. 3 is a fragmentary enlarged vertical se'cti''nof'the boom and its pivot mounting structure. l
Fig. 4 is a side kelevation 'of 'the paint pot dtalied partly in section and with the coverremv'ed.
Fig. 5 is 'a side elevation "of the 4pair'lt pot civerland `parts connected thereto; the cover being detached from the 'pot and partlyin section. n Y
Fig. 6 is an elevation, partly Vin section, Loffthe fixed switch 'and connector unit for the 'paint'pouby means of 'which electric heat is supplied 'to the paint pot; the latter being 'shown as connected to s'aid unit.
Referring 'now more `particularly to the characters Y'of reference o'n the drawings, the conventional spray booth 1, in which a car 2 to b@ Spray-painted is'dispo'sed, i`ncludes 'a ceiling 3 supported by joists 2l.
The improved spray-painting system or equipment, which is mounted in such booth, i's constructed Vas follvvs:
`Mounted centrally ofthe ceiling on adjacent joists dois a rigid horizontal framel 5 which supports, byjstiita'bly braced clamping collars 6, Va 'depending 'sleeve 7 which extends a very short 'distance only below the lceiling.
Turnably projecting through thefsleeve `is a tubular spindle Shaving a cap 9 resting on the upper'endoi the sleeve 7.
yThe spindle 8 depends 'below the 'sleeve some distance, and projecting 'from and rigid with the depending 'portion of the spindle is a boom, 'indicated -generally at10. This boom includes a pair of vertically spaced, generally -parallel tubular arms lll 'preferably disposed with a slight downward slope and connected at their outer end by a vertical sleeve 12.
The total length of this portion 'of the bom lis somewhat less than half the width of the spray booth which is customarily longer than it is wide.
The boom also includes a relatively short extension 13 which include a spindle 1'4 turnable in the sleeve 412, a lower horizontal arm 15 projecting from the lower end of thel spindle, and a vertical sleeve y1&5, open at its lower end, upstanding from the outer end of arm A15.
The spindle 8 is arranged for Vunrestricted rotation in sleeve 7, but the spindle 14 may only turn 90 degrees from an alined position ofthe extension 13 with the main boom arms 11; a rotation-limiting'pin and` notch unit 1'7 being provided on the spindle 14 and sleeve 12 for this purpose.
The paint pot, indicated generally at 18, and which is ofspecial construction as hereinafter described, includes a rigid upwardly projecting stem 19 on one side and which removably projects into sleeve 16 from its lower end so that the ypot is held in an upstandin'gjposi tion beyond the extension 13, as shown in Fig. 1.
To removably retain 'the sternin place, said stem 4is formed with a lug 2? intermediate its ends, non-turnably fitting in a hood 21 formed laterally with "and extending upwardly from the lower -end of the sleeve r16. The lug is engaged from below by 1a ielea'sa'ble holding arm 2.2 pivoted in the `hood and projecting below the saine for manipulationtsee Fig. 2). I n r The paint pot 18 comprises an outer shell Z3towhich the stem 19 is connected, van inner'paint'receiving receptacle '24 1s'r'iaced `from the's'hell 23,'ard Yan intermediate Patented Apr. 3o, 1957 p 3 shell 25 spaced (except at the top) from shell 23 and receptacle 24.
At their upper end, the vshells converge to the rim of the receptacle and are clamped together by the depending rim flange 26 of the receptacle, as shown in Fi 4.
gThe space between the shells 23 and 25 is lled with heat insulating material 27, while a suitably insulated thermostat-controlled electric heating element, indicated diagrammatically at 28, is disposed in the space between shell 25 and receptacle 24.
The lead Wires 29 extend from element 28 through the stem 19 to the upper end thereof, connecting to terminals 30 exposed at the upper end of the stem for engagement with cooperating contacts of a current supplying unit, as will hereinafter be described.
The pot 18 includes a heat-insulated cover 31 removably seated on rim flange 26 and held in place with a pressure tight fit by suitable screw-clamp units 32 mounted on flange 26.
Secured on the cover and communicating with the interior thereof is a double-ended fitting 33, and another fitting 34 on the cover connects to a depending tube 35 of a length such as to depend nearly to the bottom of receptacle 24. The titting 33 includes a pressureregulating valve unit therein.
A exible hose 36 is releasably coupled, as at 37, to one end of the fitting 33 and extends thence through an opening 38 in the upper boom arm 11 and along said arm and into the tubular spindle 8 to connection with a swivel fitting 39 mounted in the cap 9, as shown in Fig. 3.
Another hose or pipe 40, leading from a source of air pressure, is connected to the fitting above the cap.
Another length of hose 41 is connected to the other endof tting 33 and extends to a hand-operated spray gun 42 of conventional form.
Another similar length of hose 43 extends from fitting 34 to the gun; the hoses 41 and 43 being only long enough that the gun may be manipulated over a comparatively small area of the car without any movement of the boom.
Mounted on a wall of the shop outside but adjacent the booth, as shown in Fig.` l, is a bracket 44 on which a vertical sleeve 45 is mounted; this sleeve being open on its lower end and the same diameter as sleeve 16 so that the stem 19 of the paint pot may be projected into said sleeve 45.
The lug of said stem is then engaged by a holding lever 46 arranged the same as lever 22. When the stem 19 is so mounted, the terminals 30 thereon engage a pair of spring-pressed contacts 47 mounted in the upper portion of the sleeve 45, as shown in Fig. 6.
These contacts are connected to the wires 48 of an extension cord 49 which extend to a junction box 50, or the like. Since the contacts and terminals, when engaged, are completely and deeply enclosed, there is no chance of any sparks being exposed to the outside of the sleeve as the contacts and terminals are engaged or separated.
In operation, the paint supply in receptacle 24 is first heated by inserting stem 19 into sleeve 45 until the paint has `attained the desired heat, the cover remain-v ing on the pot; the hose 36 being disconnected at tting 33. The pot is then mounted on the boom extension, and upon connecting the air hose 36 to tting 33 and turning on the air pressure in said hose, the spray painting operation may be started and continued to completion of the job without any stops for paint replenishing being necessary since receptacle 24 is of ample size to hold enough paint for any one car and, as previously stated, the pot construction is such that the paint va'll retain its heat for the duration of such complete painting operation.
The articulated boom enables the paint pot to be shifted both lengthwise and laterallyof the car as the painting progresses; the extension 13 turning about the sleeve 12 as may be necessary by reason of the relatively narrow width of the spray booth or because of the desirability of maintaining the pot as nearly overhead to the area being painted as is practicable since the hoses 41 and 43 are purposely not overly long. The extension can thus be turned about the sleeve 12, or the whole boom may be turned about thc sleeve 9, by merely pulling on the hose one way or the other.
The boom is thus long enough to reach from end to end of the longest car, yet may be adjusted to enable the relatively close-together sides of the car to be conveniently painted.
From the foregoing description it will be readily seen that there has been produced such a device as substantially fulfills the objects of the invention, as set forth herein.
While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.
