METHOD AND MEANS FOR MIXING AND APPLYING INSULATING MATERIAL Filed May 11, 1929 FoqHMobley. AlfredMJZrt Vaden JHaddau/ay.

' AND VADEN J. HADDAWAY, OF WYOMING, DELAWARE -METHOD AND MEANS/FOR MIXING AND AIEfPLYING INSULATING MATERIAL Application filed May 11,

Figure 1 is a diagrammatic view, showing an apparatus such as we employ, and illustrating its use in a general Way, and

Figure 2, a sectional view through the gun for directingthe material onto the surface to be covered.

In the drawings, reference letter A indicates a container for containing liquid adhesive under pressure; B a container for containing ground cork under pressure; and C a compressed air chamber or cylinder.

The applylng gun consists of a palr of tubular arms and 11 joinedat their forward end to a hollow spherical mixing chamber 12 and diverging rearwardly, the arm 10 being connected by a tube 13 to a ground cork container and the armll being connected by a tube 14 with a liquid adhesive container. Tubes 15, 16 and 17 for conducting air under pressure from the compressed air cylinder are oined to the top thereof, tube 15 leading into the ground cork cylinder, tube 16 into the top of the liquid adhesive cylinder, and tube 17 into the hollow arm 10 at a point beyond its connection with the tube 13. The air supply from the compressed air cylinder is controlled through said several tubesby valves 18, 19 and 20 respectively.

In arm 10 is mounted a valve 21 controlled by a hand screw 22 by which the supply of ground cork passing through this arm may be regulated. Arm 11 at its discharge end has a spray nozzle 23, as shown. Mounted on the spherical member of mixing chamber 12 said nozzle may be turned into any position enough to cause the cork to feed into the arm 1929. Serial No. 362,316.

necessary to maintain its front end parallel with the Work.

In operation the air in the upper end of the ground cork cylinder is maintained at a pressure suflicient to cause the ground cork to pass through the tube 13 into the arm '10, and it is then taken up by the jet of compressed air coming through tube 17, regulated by valve 20, and driven under considerable pressure past regulating valve-21 into the hollow mixing chamber formed by-th'e member 12 and the throat of the nozzle 24. It will be understood that the pressure in the ground cork cylinder coming through tube 13 is maintained high 68 10 in the volume required, and that the air pressure coming through tube 17 is much higher and calculated to drive the ground cork from this point into the throat of the nozzle with'considerable velocity. The liquid adhesive in tank or container A is likewise forced by pressure in the upper end of said tank through the 'pipe- 14 into arm 11 and through the spray nozzle 23 into the throat of the nozzle 24 and the chamber within the member 12. The ground cork and the liquid adhesive come together at this point and the liquid adhesive being in the form of a spray they commingle and mix, forminga sticky, flufi'y mass filled with air cells, but of a plastic as Well as a sticky nature, and this mixture thus formed in this chamber is driven by the air blast coming through the arms 10 and 11 onto the surface in front of the nozzle 24, this nozzle being held by hand and moved I as may be required to spread the insulating mixture over the surface to the thickness and density desired. I

An insulating mixture is thus formed that is yery eflicient and inexpensive and may be rapidly appliedto the sheathing or other surface composing either the inside or the outside of the wall, all as will be readily understood.

Instead of mixing I the insulating material .consisting of the ground cork and adhesive is a discharge nozzle 24, the connection being I in the nature of a ball and socket joint,'so that as herein described, it may be found vexpedient, taprepare the mixture and apply it by a blast direct from the container, and thus reduce 1d the cost of the apparatus and simplify the method.

It will be obvious to those skilled in the art that various changes may be made in our device without departing from the spirit of the invention, and We, therefore, do not limit ourselves to what is shown in the drawings and described in the specification, but only as set forth in the appended claim. Having thus fully described our said device, what we claim as new and desire to secure by Letters Patent, is:

In an apparatus for applying plastic material to surfaces, the combination of an adhesive container, a ground-cork container and a compressed air container, of a mixing nozzle comprising-an adjustable flared mouth provided with a socket, a hollow ball providing a mounting for said socket, radially mounted square tubes communicating with said hollow ball, one of said tubes for conducting an adliesive under pressure, the other tube for conducting ground cork under pressure, a restricted nozzle in said first mentioned tube for spraying said adhesive, an agitating means for said ground cork comprising anlnclined nozzle in said second mentioned tube, means I for admitting air under pressure to said inclined nozzle, and an adjustable re fulating valve for said ground cork positioned between said inclined nozzle and said flared mouth, substantially as set forth.

In witness whereof we have hereunto set our hands at Baltimore, Maryland, this 8th I day of May, A. D. nineteen hundred and twenty-nine.
