ICREMATORY Filed Sept. 27, 1926 2 Sheets-Sheet 2 Patented Jan. 7, 1930 UNITED STATES PATENT OFFICE ARTHUR MANN, OF NYACK, NEW YORK, ASSIGNOR, BY MESNE ASSIGNMENTS, TO MORSE BOULGER DESTRUOTOR (10., A CORPORATION OF DELAWARE GREMA'I'ORY Application filed September 27, 1926. Serial No. 137,855.
This invention relates to improvements in Crematories and has for an object to provide a device of that character in which the furnace may be charged with the remains to be cremated through one wall in the presence of the observers after which the charging opening is closed while all of the operating apparatus is located in and associated wlth another wall so that the operation may be carried on without coming under the observation of the persons attending the cremation. Other objects consist in the provision of a support located beneath the main hearth and beneath the passage at one end of the hearth to permit support of a container or receptacle into which the ashes from the ore mation may be collected and readily removed; also in the provision of such a support coacting with the main hearth to form a restricted passage for the gases of combustion beneath the hearth; also in the provision of a final combustion chamber beneath the main hearth; also in the provision of means to supply heat to maintain and enhance combustion in both the main and final chambers; also in the provision of air ports leading from circulatory passages to the interior of the chambers to supply air for combustion thereto; also in the provision of a new and improved closure structure associated with the charging opening. These and other obj ects will be made apparent and more fully set forth in the following specification and shown in the accompanying drawings in which Fig. 1 is a vertical section through a crematory embodying my invention.
Fig. 2 is a transverse vertical section through the same.
Fig. 3 is a horizontal section through the closing doors illustrating the construction thereof.
Like numerals refer to like elements throughout the drawings in which 10 indicates generally a crematory or furnace having its walls constructed of suitable refractory blocks or tile and surrounded and en closed in brick and other insulating materials. The crematory is provided with a main combustion chamber 1O at the bottom of which is provided a hearth 11, having the horizontally arranged supporting tile 11 and the horizontally arranged arch tile 11 (see Fig. 2 for example). This hearth ex.- tends from the end wall 10 of the furnace and is interrupted short of the opposite end wall 10 to provide a passage 10 Located beneath the passage 10 is the arched support 12 extending from the end wall l0 and underlying the hearth 11, being spaced therefrom to provide the continuation 10 of the passage 10 Located beneath the hearth 11 at the end of the passage 10 is the second chamber 10. Leading from the chamber 10 is the passage 10 which leads to the outlet or discharge port 10 arranged to communicate with the stack duct 14, communication thereto and through being controlled by the sliding damper or gate 15. (See Fig. 1.) In the rear end wall 10 of the furnace or crematory is provided the fuel supply opening 10 communicating with the main combustion chamber 10 and a second burner opening 10 communicating with the second chamber 10 A burner and supply tube indicated by numeral 16 projects into each of these supply openings and is arranged to supply fuel for combustion and cremation. In the side walls of the furnace outwardly of the refractory lining are air passages or manifolds 10 from which lead ports 10 to the chambers 10 and 10 for the purpose of supporting and render ing complete the combustion carried on in said chambers.
In the front wall l0 is the charging opening 10 with which coacts the sliding gate'18 of refractory material. The port 10 is continued outwardly of the gate 18 through the brick casing and is closed at its outer-end by hinged doors 20 shown in detail in Fig. 3. These doors interfit as indicated and are each constructed of a casing of metal such as bronze or cast iron indicated by 20 In the inner portions of the casing is located suitable insulating material 20 such as sil-ocel which is spaced from the walls of the casing to provide air spaces 20", this spacing being maintained by the ribs or flanges 20. Ports 2O at top and bottom of the casing 20 permit circulation of air through spaces 20 as will be obvious, thus assisting to insulate and cool the metal casings so that they may be handled without danger or injury, even during cremation. i
The wall 22 of the room in which the observers are located is provided with the opening 22'in alignment with the opening 10 to permit insertion of the casket or other container with itscontent through the opening 10 uponthe hearth 11, this charging action beingassisted by use of rollers or the like where desired. After the hearth 11 is charged the refractory door 18 is lowered and the doors 20 closed. Cremation is then initiated and carried onuntil' ultimate destruction of the remains is effected, this operation being conducted out of sight of the observers, who only need seerthe initial charge of the crematory. 7
After destruction of the corpse, the ashes, or so much thereof as are desired, are pushed from the hearth into the passage 10 where they fall into the receptacle 25 placed there for that purpose upon the support 12. After the receptacle 25 is charged, it may be Withdrawn through the port of access indicated in dotted lines by numeral 10".
In cremation'it'is desirable to effect complete combustion of the gases generated from the creation and to accomplish this purpose I provide additional air through orts 10 and reverse the flow of the gases 0 combus- 1 tion beneath and in contact with the hearth 1]. toenhance the combustion effect. Such gases flow into the chamber 10 where expansion and completion of the combustion of any unburned gas or the like is effected with or without the assistance of the burner projecting through: the opening 10 as may be advisable or desired. 7
An opening 10 is provided in the end wall 10 for access to the hearth 11 for cleaning or removal of the ash, a door 27 normally closing this opening. A similar port 10 communicates with the second chamber 10 and is provided with a door 28.
.A port of access 10 is provided at the front end of the passage 10' as indicated in dotted lines in Fig. 1.
The considerable travel of the gases in the furnace above and beneath the refractory hearth 11 ensures a quick, efficient and complete destruction which is highl desirable in the operation of structures 0 this character. As stated also, the observer is subjected only to witnessing the deposit of the remains in the crematory, thereafter escaping the unpleasantness of having to observe the operating of the furnace and the cremation.
It will be obvious that my invention is susceptible of modification and variation from the embodiment described and shown, and I 7 do not wish to be restricted to such showing and description except as defined in the appended claims. 7
combustion space underneath said hearth and beyond'said shelf to effect a reduction in gas velocity to permit. the settling of ash earned by the gases, said chamber also having auxiliary supply openings therein;and an ash removal opening opposite said ash shelf.
2. A crematory comprisingin combination a refractory chamber having a charging opening in the front wall thereof and a hearth opposite said opening and terminating short of said front wall, an ash shelf'below the space between said hearth and front wall and providing a space underneath said hearth for the passage of gases,said chamber being constructed and arranged to provide an enlarged combustion space underneath said hearth and beyond said shelf to effect a reduction in gas velocity to permit the settling of ashfcarried by the gases, said chamber also having auxiliary supply openings therein, an ash removal opening opposite said ash shelf and cleanout doors opposite said hearth and the bottom of said combustion space.
3. A crematory comprising in combination a refractory chamber having a chargin opening in the front wall thereof and a heart opposite said opening and terminating short of said front wall, a door for said charging opening and an'intermediate refractory 010- 7 sure to protect said door from theheat in said chamber, an ash shelf below the space between said hearth and front Wall and pro-.
viding a space underneath said hearth for the passage of gases, said chamber being constructed and arranged to provide an enlarged combustion space underneath said hearth and beyond said shelf to effect a reduction in gas.
velocity topermit the settling of ash carriedv by the gases, said chamber also having auxiliary supply openings therein and an ash moval opening opposite said ash shelf.
In testimony whereof, I have signed my name to this specification.
