name MIXING PLASTIC MATERIAL.
Application fled April 20, 1925. Serial No. 24:411. I
i This invention relates to a method of treating plastic material, and the embodititious material which is light in weight and provided with air or gas pockets, thereby addingto the heat insulating qualities of the material. This maybe efl'ected by introducing air or gaseous particles into the material while the latter is in a plastic state and holdin the bubbles of air or gas in the mass until it has set. This provides a porous cementitious bod The air or gas should be uniformly distributed throughout the mass and also preferably should'be in minute bubbles. This may be accomplished by the mixer disclosed herein, and wherein air or gas is introduced into a mixing cham-' ber, distributed and beaten into the mass by means of mixing blades or a itators.
' These objects together wit other objects and corresponding accomplishments may be efl'ected by employing the means illustrated in the accompan g drawing, in which:
Fig. 1 is a perspective view of a mixer; Fig. 2 is a transverse section through the mixer;- Fig. 3 is an axial section through one of the air nozzles; and Fig. 4 is a plan view as seen on the line 4-4 of Fi 3.
Referring more particularly to t e draw- P ing, a vessel or trou h in which the mix is produced is indica by 5. Journalled in the end walls of the trou h is a shaft 6, upon which are mounted b ades 23 for the purpose of agitatin the ingredients and scrapin the cement rom the bottom thereof. These lades are suitably disposed and spaced on the shaft. Mounted upon the trough are air nozzles 7 connected to a common manifold. 8 to which air is supplied from a souree of compressed air througha pipe 9, such asa flexible hose. The air nozzlesare the same in construction and are spaced as found convenient. They comprise cylindricaf casings 10 sions 11 which are reduced in diameter and externally threaded, so that each casing may be introduced into and secured in a threaded openin in the wall of the trough.
' Each casing 10 as a plunger chamber communicatin'g through a bore 11 with p the having exten-- trough. The end of the chamber is inter-. nally threaded and a plug 12 having a bore for a plunger stem is secured therein. A lateral nipple 13 communicates with the chamber, and a coupling 14 connects the manifold 8 to the casmg.
Mountedwithin the chamber of the casing 10 is a plunger 15 having projecting therefrom a cleaning stem 16 adapted to enter the outlet bore of the nozzle. When the lunger 15 is moved to cover the portopenmg from nipple 13, pin. 16 is in t e bore of the nozzle. Communication is then cut ofi between the nozzle and the air supply. The pin 16 prevents the entrance of plastic material into the nozzle mouth and also cleans the latter. Connected to the'plunger 15"is an. operating stem 17 having a hand wheel 18 secured to the end thereof. 'The hand wheel is provided with a hub from which extends a locking-pin 19. Encircling the stem 17 is a compression sprin 20. The plug 12 has a cylindrical extension 21 provided with a bayonet slot 22 to receive the pin 19. v
Water, plaster, and such other ingredients as are desired are introduced into the trough 5, the shaft 6 is rotated, plungers 15 are retracted to open the air nozzles, and air enters the trough being beaten or whipped into the mixture by the paddles which move soas to drag the air downwardly with the action of gravity into the mass. This also acts to a itate and mixthe ingredients. Minute bu bles become distributed throughout and suspendedin the mass.
After the mixture has been sufiiciently treated, the Inn ers 15 are projected by pushing the and wheels 18 inwardly so that ins 1'9 enter into the bayonet slots 22, the w eels then being turned to, dispose the pins 19 in looking position. In this position, the cleaning pins 16 fill the nozzle 0. rtures and push any cement outwardly.
e' trough can now be turned to empt it of the plastic mass. The latter is use in the manner common for plaster board, in setting and forming a porous or spongy bod V hat I claim is: 1. The method of aerating a mass of plaster' which consists in placing such a massinto a chamber, introducing a gaseous agent thereinto at the periphery thereof, and
creating a whirling agitating movement so as to drag said agent thereinto with the action of gravity and entraining the same in the body of said mass.
2. The method at aerating a mass of 5 plaster which consists in injecting a gaseous v agent inwardly into-the mass at dispersed points, and mechanically creating a Whirling beating movement transverse to the path of the agent and with the action of gravity into said mass so as to entrain. the same 10 therein.
In witness that I claim the foregoing I have hereunto subscribed my name this 7th 'day of April, 1925,
