PROCESS OF FORMING RECEPTACIJES.
Application iled` JanuaryiZG, 1923. Serial No. 615,025.
'To all whom t may concern Be it known that I, CHARLES, MATTHEW MAYO, a citizen of the United States, and a resident of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Process of Forming Receptacles; and I do hereby declare that the following is a full, clear, and eXact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.
This invention relates to a process, of forming or molding a cooling chest or like receptacle formed of a plastic composition, wherein the same may be provided with water chambers and communicating passages about its sides, end and bottom so that the water chambers or passageways may be filled from a single opening and may circulate about the walls thereof. Reference may be had to the application of Charles .Mayo, filed October 23, 1922, Serial No.
596,372 for iceless refrigerating chest.
The principal object of the invention resides in the method of casting the walls, and particularly the bottom of the structure, and the means of forming communicf'itingv passageways within said walls and bottom, whereby the cooling chest or like receptacle may have its walls and bottom cast integral and provided with strengthening ribs, while having formed enclosed and entirely within said walls and bottom, communicating passageways or water containing chambers.
The full nature of this invention will be understood from the accompanying drawings and the following description and claims. y
In the drawings Fig. 1 is a perspective view of the cooling chest. Fig. 2 isa central vertical section through the mold and extending longitudinally thereof. showing the chest partially formed in inverted posi- Fig. 3 is the same as Fig. 2 showing the method of forming the bottom upon the chest. Fig. l is a section taken on the line 1 -4 of Fig. 3. Fig. 5 is a plan View looking down on the structure shown in Fig.. 2.
Fig. 6 is an end elevation of the mold shown 1l and ends 12 which are provided vi''ith` recessed decorative portions 13. Said sides 'and ends are provided about their top with an offset forming the shoulder .14 for receiving. a suitable lid, not shown herein. yThe boX is formed of a specially prepared plastic composition which is sufliciently porous to permit the comparatively rapid evaporation of a liquid, such as water, for providinga cooling effect to the interior of the box, To this end it is necessary to provide water containing chambers in the sides, end andbottom,v all of which communicate with eachother for permitting the free circulation of water for absorption `and evaporation.- l
. The process ofQcasting ,and forming the box so that the walls and bottointhereof will be Vformed integral with each other with the l"neces sary chambers or-passageways cast therein, comprises the formation of an outer shell or mold 15 comprising two diagonally opposed removable sections. Each section of the mold 15 consists of one end and a side,.a'nd is formed of suitable metal plate provided with an angularly extending flange 1,6 at. diagpnally opposite corners so are ranged as to be removably secured by the bolts 17 to, similarly abutting flanges on the corresponding diagonally opposed section. The inner face of'each. of the sides of the outer, mold 15 is provided withraised surfaces 18 for forming the decorative panel recess 13, as shown in Fig. l. After thesections of the louter mold 15 are `secured together by the bolts 17 so as to forma rectangular mold, .i't is placed on the .pallet board 19 which has its edges offset, las
shown lin Figs. 2 and 3, for forming the Oif- 'set 14 aboutthe top of the chest.
Positionedwithin the outer mold 15 there is an inner mold 2O of similar dimensions so as to fit within the outer mold and be positioned thereo'ver "a distance equal to the desired thickness 0f the surrounding walls to be cast. Said inner mold is provided with a top plate 21, and rests upon the raised portion of the pallet board 19. Upon the two molds 115 and 20 being vpositioned upon the pallet board, the composition 22 to be molded is poured between the sides thereofand tamped ,and pressed down yin the usual` manner. AThe end core. plates 23'and the side corel plates `24E fare then y placed in position. Said core plates are formed of metal of fa thickness equal to the desired width "'f the passages or chamber, andof downwardly through the material 22 soA that the end plates 23 abut the surface of the pallet board, while the side plates arel withheld from the pallet board so that the lower ends thereof are spaced from the sur-` face. F or centering the plates, the inner bolts 26 and outer bolts 27 are provided, which screw through the forms 2O and l5 respectivel-y so as to engage'the sidesof said core plates and space them properly between said forms. y
After the material 22 has set a suflicient length of time with the core plates therein, so as to hold its shape and be self-supporting, the plates 23 and 24 are withdrawn, leaving a lcorresponding chamber or passage 22%,the material remaining set in the formshown in Fig. 2. Upon the withdrawal ofthe plate, the screw bolts 27 are removed and the hole left thereby is plugged up by inserting the material 22 therein. The form is then made ready to mount they bottom thereon. c For forming the chamber or pas sage in the bottom of the chestr the core plates 30 are employed, which are adapted to extend through the slots 3l yin the out'er form Said plates, after beinginserted through said slots. are laid upon' the material 22 supported on the top 2l ofthe 'frame 2O so that the further vedge the plate 30 is flush with the end chambers or passages 28. The material is. then built up to a level with the top surface of the plates 30, joining said plates with each other and with the side chambers or passages 28,7a`s shown in Figs. 2 and 5 and by dotted lines in Fig. 4. The built up portion of the material leaves a communicating passageV 34 between them over which a thin Zinc plate 35 is mounted. The composition 22 is'then placed on top of the plates 8O vand thezinc plates and provided withan embedded strengthening wire mesh 36.1 The legs 37 are then built up and silent domes 38 are embedded therein for supporting` the chest when finished. After the material formed o ii the bottom has become set, and of suilicient strength to be self-suppoi'tiug, thc plates 3() are pulled out through the slots 3:1., lea-ving a chamber oi' passage in the bottoni which is in communication with the end passages 28 and also in' communication'between themselves and the side passages 38 through the passages 34 left open by the Zinc plates 35. I
After the composition' has become l thoroughly hardened, the mold is removed from the pallet board, the bolts 17 removed from the flanges 16 and the outer mold l5 is taken ofi". The'chest -is then set upright, andthe screw bolts 2,6 are removed.I The colored, after which a suitable top may be placed thereon. lt will be observed that the chambers or passages formed by the several core plates and zinc plates 35 will be inter- 'communicating through the bottom of the chest so that there may be a free circulation of water to all the walls thereof.
The invention claimed is: The process of forming a receptacle having plurality of inter-communicating chambers formed in the walls thereof, consisting `of mounting an inner form within spaced from an outer form, filling the space between said forms with a plastic material, embedding therein a core plate adapted to be pulled therefrom leaving the desired chamber formed therein, and screwing into said forms means for spacing said plate therefrom.
2. T'neprocessl of forming a receptacle having a plurality of inter-communicating chambers formed in the walls thereof, consisting of mounting an inner form within and spaced from an outer form, filling the space between said forms with a plastic material for forming side walls, embedding thereina core plate adapted to be pulled therefrom leaving the desired chamber therein, providing a horizontal bottom supporting plate on the inner mold for supporting the composition formed thereon, mounting thereover a horizontal core plate, forming ya layer of material over said core plate, and slidably removing said plate upon said material becoming set, whereby a chainber will be left formed in the bottom and in communication with the chamber formed in the sides.
