mixtures, or any other suitable or desired liquids.
One of the objects of my invention is to thoroughly disintegrate the materials to be s rayed into a very fine mist andto deliver t e same with suflicient force to the object to be treated to thoroughly and completely coverthe surface thereof.
Another object of my invention is to de liver or shoot the spraying material without causing excessive wear on the parts of the machine and to prevent the accumulation and building up of concrete or the particular material used, on the parts of the machine. This is done by providing means whereby the material does not come into contact with that part of the machine or apparatus which directly projects or discharges the wet material upon the object being treated; or in other words, the wet material when leaving the machine is shot clear thereof. This-is accomplished by providing a belt of air or an air trough, onto which the material drops at the discharge end of the machine, and is absorbed thereby and when carried to complete operation, is broken up into a fine spray or mist, and is carried withthe force of the air to the object to be treated.
The invention has among its other objects the produdtion of a device of the kind de scribed which is simple, convenient, coinpact, durable,reliable, efficient and satisfactory for use wherever found applicable. Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosures herein given. 7
To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.
In the drawings, wherein like reference characters indicate like or corresponding parts,
4 Fig. l is a top plan view of my device; showing the hopper in section.
Fig. 2 is a front elevation of the same;
Fig. 3 is a sectional view taken substantially on the line 33 of Fig. 1;
Fig. 4 is a side elevation of my device;
- Fig. 5 illustrates a side elevation of another modification of my device;
Fig. 6 is a front elevation of the same;
7 is a sectional view taken substantially on line 77 of Fig. 5;
Fig. 8 illustrates another modified form of device; and 70 Fig. 9 illustrates still another modified form of device.
In the drawings, wherein I have illustrated the preferred embodiment of my invention, there is shown a portable spraying machine that may be strapped to and carried by the workman from place to place as desired. A hopper 1 is provided to receive the material to be sprayed, said hopper being of any desired mm and sha e, and havv readily drop through the discharge outlet 2.
It is to be understood that the machine is pri- 00 marily intended to handle a heavy viscous material such as cement or the like and in the claims the term heavy viscous is intended to apply to such materials to distinguish them from dry or free running materials, but where the material to be sprayed is not viscous, or in other words is free-running, such as whitewashing materials, the agitating shaft and pins may be dispensed with if'so desired, as in that case the free-running materials will tend to discharge by gravity alone. A door or valve (Fig. 4) 0 rated bya hand knob 6, may be rovide in order to regulate or adjust the ow of ma-v providedfor the fan .as desired.
'feet per secon Projecting downwardly into the throat 9 and leading from the discharge outlet 2 is a spout or lip 10, (-Fig. 2) said spout also projecting slightly forwardly of the throat and terminating substantially at the open end thereof.
The spout 10 is preferably set into the throat at an angle sloping toward theouter end of the throat in order to provide an easy slope for the outgoing air, and also to direct the air to the lower edge of the spout, whereby the falling material is picked off and carried forward by the rapidly moving air.
The throat 9 is preferably enlarged or outwardly beveled at its open end, as at 11, (Fig. 2) for a purpose to be hereinafter described.
The air is discharged from the throat at a high rate of ed (preferably about 200 d and creating a belt of air beyond the throat on which the material dro ped' from the spout is conveyed to the 'sur ace or'object'to be treatedi -As shown in Fig. 3, the material as it falls from the spout will fall onto the belt of'air shot out by the fan, said-air preferably forming a trough for the material, and will also be carried forwardly due to the force or pressure of said air. During the carrying of the material the particles thereof will become to an extent absorbed by the air, so that atadistance of about 18 inches or more from the throat in the particular size and type illustrated, the particles will be so finely divided as to be substantially in the form of a mist and hence will completely and thoroughly cover. the surface to be treated.
Any form of drive may-be provided for rotating the agitator shaft 3, as for instance, a motor 12, and similarly any form of drive may be provided for the fan 8, as for instance a second motor 13,.there being electrical connections 14 and 15 to said motors to 'drive them. Operating or carrying handles 16 may be conveniently arranged at the sides of the machine, or otherwise whereby the machine may be manipulated during the operation thereof, and a loo 17 (Fig. 4) may be arranged on the mac ine in order that it may be carried by a belt or the like, strapped about the operator.
It is to be understood that the air that is forced through-the throat 9 may be con-.
. chine,-there will be no wear or similar injury to said moving parts. Furthermore, due to the positioning of the spout .at the extreme end of the throat, all of the material will be carried awa by the air belt without any possibility of ropping on the sides of the throat, and hence will not build up or cake thereon. It is. preferable to employ the spout 10to conduct the material from the hopper to the throat, because if the material were dropped directly from the hopper into the throat, then the strong current of air would tend to prevent the material from falling through said feed opening, and the material would soon bank up "against the upper wall of the spout and throat and clog the machine.
In the modification shown in Figs. 5,6 and 7, the device is showmas mounted upon .a wagon or wheel base, there being a bottom or'truck portion 20 for carr ing the machine and transporting it from p aceto place, and having a turn-table or bearing portion21 at its upper end, whereby the sprayer 22 may be rotated in a horizontal plane. A second pivotal connection'23 is that the sprayer may be rotated 1n a vertical plane, so that therefore a universal pivotalmovement of the s ra er is obtained. A latch 24 is provide w ereby the machine may be locked in position. i
In this particular embodiment there is shown a fan 25 .driven'b a motor 26, said fan-having a discharge tllroat 27. A hopper'28 is provided with a spout 29 substantially similar to the spout 10 previously described and preferably sloping forwardly of the -throat 27 in like manner, so that the material dropping through the spout 29 will fall onto a belt of air, the air trough starting from the throat 27 in this same manner as hereinbefore described. 1
In the modification shown in Figure rovided so The motor, fan and base may be transported there is shown a fan driven by a motor 31 and mounted upon a suitable base 32.
to any desired location and connected to a conduit or tube 33 having a discharge throat 34. A hopper 35 is arranged above the discharge throat 34 and has a spout 36 projecting downwardly and forwardly thereinto, in the same manner and for a like purpose as spouts 10 and 29 previously described.
In the modification shown in Figure 9 there is a hopper 37 having a discharge spout 38 at the lower 'end thereof projecting forwardly and downwardly of a throat portion 39.- Air from an source under pressure is conducted througl a the conduit 40 and through the throat 39, there being a valved connection 41 for controlling the admission of said air into said throat. In this instance, as in the previously described modifications, the air discharged through the throat 39 under pressure will form a trough or carrier belt for receiving and carrying the particles of material dropped thereonto through the spout 38. By the expression close to or in proximity to the delivery or discharge end of the machine, I mean at such a point adjacent the discharge end that any drooling or dripping of a comparatively heavy viscous material. like cement. will not occur.
Having thus described my invention it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, arrangement. construction and combination of parts herein shown and described or uses mentioned.
What I claim as new and desire to secure by Letters Patent is:
