Abstract
Description
- This invention is directed to compressed air operated hand held spray guns for applying finishes to walls and similar surfaces.
- It is known to apply plaster, stucco and other textured wall finishes using hand held spray guns operated by compressed air. A typical spray gun used for this purpose is that sold by Bliss & Laughlin Industries under the trade mark GOLDBLATT. These spray guns are essentially adaptations of the compressed air operated spray guns utilized to spray paints and lacquers, modified so as to be able to handle sprayable materials of various textures and consistencies. Such guns are inevitably prone to occasional blockage, jamming and damage by the material being sprayed, and since it is often impracticable to dismantle the gun to correct such problems on site, an adequate supply of spare guns must be available. Moreover, such guns are neither designed for nor capable of spraying the coarse particulate materials used as a surface layer on some types of wall finish such as pebble-dash.
- It is also known to provide fluid operated guns to project a stream of sand or grit for cleaning and removing previous finishes from walls by sand-blasting, but these are clearly not suited for applying particulate material to an unhardened wall finish, nor even if adapted for this purpose would they have the versatility to handle a wide range of particulate materials with a readily controllable rate of' application. Moreover most such blasting guns require a fairly sophisticated system for delivering the particulate material.
- The applicant is seeking to provide an air operated gun which is adaptable not only to applying particulate material to plaster, but will also apply the plaster itself, whilst being of a construction which not only minimizes the risk of jamming or blockage but permits ready disassembly on site should a problem occur.
- According to the invention, there is provided a hand held compressed air spray gun comprising a stock merber supporting a tubular housing, defining a uniform cylindrical bore having front and rear ends and an aperture in the wall of the bore near its front end, and a trigger mechanism external to the tubular housing, a breech block secured in the rear end of the bore, at least one barrel assembly including a cylindrical barrel receivable in the front end of the bore, said barrel defining an opening at a muzzle end and an aperture in a cylindrical wall of the barrel axially adjacent the aperture in the tubular housing, an air pipe extending axially relative to the barrel from a connection at its rear end for coupling to a source of compressed air forwardly through a breech end of the barrel and terminating in a nozzle within the barrel, means releasably coupling the rear end of the air pipe to the trigger mechanism when the barrel is located in the bore so that the rear end of the air pipe extends rearwardly through a bore in the breech block, whereby to retain the barrel assembly in the housing.
- This provides a structure which is easily dismantled and cleaned, since the trigger mechanism is wholly external to the barrel, and the parts exposed to the material to be sprayed are housed in a uniform cylindrical bore from which thay can readily be removed. The barrel assembly can readily be changed to suit different materials and different modes of operation.
- Different types of barrel assembly may be used, preferably interchangeably. In one type of assembly the means coupling the pipe to the barrel is such as t.o rrestrain axinl movement of the pipe relative to the barrel, whilst permitting rotational movement of the barrel relative to the tubular housing, and wherein the barrel is provided with a handle for the manual application of rotational movement thereto whereby to adjust the degree of coincidence between the aperture in the barrel and the aperture in the housing and to control the passage of material from the hopper into the barrel for entrainment by air passed through the pipe. In another type, the means coupling the pipe to the barrel is such as to permit relative axial movement of the pipe relative to the barrel, and an aperture plate is located at the front end of the barrel, the nozzle of the pipe having a normal position closing an aperture of the aperture plate, the trigger mechanism when coupled to the rear end of the air pipe being operative to move the latter axially so that the nozzle moves between its normal position and a position inward of the aperture, whereby material entering the barrel from the hopper may be entrained by air passed through the pipe.
- The invention also extends to a hand held compressed air gun for spraying particulate materials comprising a hand held stock supporting a tubular housing, a barrel member having a breech end rotatably supported in the tubular housing, a handle attached to the barrel forwardly of the housing whereby the latter may be manually rotated relative to the tubular housing, a hopper for particulate material mounted on the tubular housing above an opening defined therein, the breech end of the barrel defining a further opening in the side wall of the barrel whereby on rotation of the barrel there is a continuously variable degree coincidence between the opening in the breech end of the barrel and the opening in the breech block, and an air supply pipe extending axially through the breech block and the breech end of the barrel to a nozzle adjacent the opening therein and directed towards the nozzle end of the barrel, whereby to eject material falling into the barrel from the hopper.
- One way of carrying out the invention is described in detail below with reference to drawings which illustrate only one preferred embodiment, in which:
- Figure 1 is a longitudinal vertical section through a preferred embodiment of a spray gun in accordance with the invention, showing one of two alternate types of barrel fitted to the gun;
- Figure 2 is a a similar longitudinal vertical section, showing another alternative type of barrel, the unchanged part of the gun being shown in outline only.
- According to the above figures the body of the gun comprises a vertical handle or
stock 2, an open ended tubular housing 4 mounted across the top of the stock, and a secondtubular housing 6 of smaller diameter extending through the stock parallel to and beneath the first housing. The second housing accomodates aplunger 8 passing throughcaps spring 14 acts between thecap 12 and aflange 16 on the plunger to bias it forwardly (to the left as shown in Figure 1). Atrigger 18 is attached to the front end of the plunger, the plunger and trigger being biassed by the spring to assume the position shown. Pressure on the trigger tends to move the plunger rearwardly. A coupling member 20 is secured to the rear end of the plunger and is releasably clamped by ascrew 22 to the rear end of anair pipe 24 which extends axially into the first tubular housing through a cylindrical breech block 26 secured against displacement by ascrew 28. Theair pipe 24 is threaded at its rear end for attachment to a compressed air line. - The
air pipe 24 shown in Figure 1 forms part of an interchangeable assembly incorporating acylindrical barrel 30 received in the front part of the tubular housing. The assembly further comprises arubber boot 32 forming a seal between thepipe 24 and thebarrel 30 whilst permitting limited axial movement of the pipe relative to the barrel, which latter is clamped in place within the tubular housing by ascrew 34 acting onflanges 36 formed on a split outer end of the housing 4. Thebarrel 30 has a nozzle opening 38 within which anorifice plate 40 is retained by asplit ring 42. Anozzle 52 screwed into the outer end of thepipe 24 normally closes an orifice in the orifice plate. Afelt washer 54 is located between thebarrel 30 and the breech block 26. - A
hopper 44 is secured by aclamp 46 to a funnel shapedopening 48 in the top of the housing 4, which opening coincides with an opening 50 in the top of the barrel so that material such as plaster placed in the hopper can enter the barrel. - When the
air pipe 24 is connected by a hose (not shown) to a source of compressed air (not shown) and thetrigger 18 is depressed, theair pipe 24 is drawn rearwardly thus withdrawing thenozzle 52 from the orifice in theorifice plate 40 so that air emerging from the nozzle entrains the plaster and sprays it forwardly through the orifice according to the conventional principle of operation of air operated gravity feed apray guns. On the other hand, as compared with conventional guns, possible causes of jamming are eliminated since the trigger mechanism and associated spring is separately housed from the gun proper, in which the only part is thepipe 24 with itsnozzle 52. Those portions of thepipe 24 which are in sliding contact with other parts of the gun are of smooth cylindrical form, and outside of the barrel itself there are no voids within the structure to become clogged or block with hardened material. The entire barrel assembly including thepipe 24 can be readily removed simply by loosening thescrews single screw 28, and upon their removal the housing 4 presents a smooth, uniform cylindrical bore. Thus disassembly and cleaning of the gun is extremely simple and there are also advantages in manufacture since the gun parts require only a minimum of very simple and straighforward machining operations. - Upon removing the barrel assembly comprising the
barrel 30 and thepipe 24, this may be replaced by the alternative assembly shown in Figure 2. This assembly also comprises abarrel 60 and apipe 62, but is installed and operated somewhat differently in order to adapt the gun for the application of solid particulate material to the surface of a previously applied matrix layer to which the particulate material adheres. - The
pipe 62 passes through an axial orifice in the breech end of thebarrel 60, and is secured against withdrawal from it hy a rubber 0-ring 64 which also serves as a seal whilst permitting rotation of the barrel relative to the pipe. In order to provide for different locations of anozzle 66 formed at the outer end of the pipe relative to anopening 68 formed in the side of the breech end of the barrel, severalperipheral grooves 70 may be provided in thepipe 62 to provide alternative seatings for the 0-ring 64. The rear end of thepipe 62 is clamped by thescrew 22 as before, but the 0-ring 64 prevents rearward movement of the pipe relative to thebarrel 60. Thus thetrigger 18 and its associated mechanism is inoperative, except as n means to hold thepipe 22 against movement and thus in turn to hold the breech end of the barrel 60) in the housing 4. - The 0-
riug 64 allows thebarrel 60 to be rotated in the housing by means of ahand grip 72 so that the degree of coincidence of theoperning 68 with the opening 48 in the housing 4 can be continuously varied from full coincidence to zero coincidence, thus regulating the rate at which particulate material can flow from thehopper 44 into the interior of thebarrel 60. - The material so flowing is ejected from the nozzle end of the barrel by air emerging from the
nozzle 66 when thepipe 62 is connected to a source of compressed air. thegroove 70 in which the 0-ring 64 is located is selected to provide the best results according to the particle size and density of the material to be sprayed. The gun is held with both hands, one on thestock 2, and the other on thehand grip 72, this second hand steadying and aiming the gun and also regulating the flow of particulate material into the barrel. - As before the structure of the gun is such that it is very easily dismantled and serviced, and the risks of jamming or blockage is minimized.
