UNITED STATES EMILE D. KRIEG, 0F NEW-YORK, Y.
VENTILATOR FOR TYPE-CASTING MACHINES.
Application 'filed October 14, 1922. Serial No. 594,547.
To all whom, it may concern:
Be it known that I, EMILE Knits, a citizen of the United States oi America, residing at New York city,,in the county of New York and State of New York, have invented certain .new and useful Improvements in Ventilators for Type-Casting. Machines, of which the following is a specification.
My invention relates to a ventilator for type-casting machines, and particularly for the ventilation of the melting'pot. The object of my invention is to provide an improved ventilator having certain ;tcharac-i teristics hereinafter described or shown in the accompanying drawings, in which Fig.1 is a'schematic view of an installation in which my invention is embodied; Fig. 2 is a broken section drawnjto: a larger scale through a melting'pot showing my improved ventilator applied thereto;
Figs. 3 and 4 are sections on the lines 33, 4- 1, Fig. 2 respectively, drawn to a larger scale; and 7 i Fig. 5 is a perspective of theloc'king ring. In the operation of typena sting machines, it is common practice to melt the type metal in a pot mounted on the machine and heated by a gas burner. The metal fumes rising from the pot, as'well astheazproducts' of combustion from "thegas' burner are both commonly discharged 'into the atmosphere of the composing room, constituting a menace to the health of the operatives. It has been proposed tocarry ofl these objectionable gases through venting flues, butthe constructions employed for this purpose have been of rather crude and "defective character. The present invention provides im roved arrangements for this purpose.
s illustrated in the accompanying drawings, the melting. pot 6 isprovided with a surrounding/jacket? sli 'htly spaced therefrom topermit the heat from the gas burner 8.to surround the pot and keep. the metal 9 therein in molten condition. .At one end the jacket is extended and provided with an upwardly extended nipplev .10 ported rat v11 to vent the products of combustion from the gas burner. A hollow standard 12 is sleeved upon the nipple 10 and leads the products of combustion from the gas burner upward therethrough to a. ventilating duct 13.
ere a number-of machines are arranged in a single room, the ventilating system, may
c mpri e a ser e 9f P pe 1% 16 a d 17 connected together by tapered Y-joints 18, 19 and 20, the pipes 14-17 being graduated to afford a stepped-up increase of volumetric capacity as they approach the exhaust fan 21 which delivers to a discharge pipe 22.
Mounted at the head of the standard 12 of each melting pot is a coned ventilating head 23 laterally apertured by three ports 24, of which two are preferably oval and one round. Swivelling thereon isa correspondingly shaped sleeve 25 at the upper end of a conduit 26- adapted to be arranged over the melting pot and having a vertically adjustable sleeve 27 normally! lowered into juxtaposition to the surface of the molten metal and serving to collect the fumes rising therefrom. In operating position the conduit communicates with the ventilating head through one or other'of the ports 24.
[Inasmuch as the. metal 9. is constantly' drawn off during the operation of the typecasting machine, it is necessary to frequently replenish the supply of. metal in the pot. Thisis commonly done by dropping into the pot pigs of type metal. In'order that this may be readily accomplished, I providethe sleeve 27 with a handle 27 by'which the operative may readily .liftit .out of obstructing position. It is desirable in some instancesto hold the sleeve 11p to permit skimming of dross or anyimpurities elf the I molten'metal. For this purpose the upper end of the sleeve is provided with a hook 27 which maybe engaged on a stud 27 on the conduit, by rotating the sleeve slightly in raised position.
. It is also desirable when cleaning the machine or making adjustments in the neighborhood of the pot, to get the conduit out of the way, so that it is not necessary to lower the pot to render these operations possible. For this purpose I provide a connection between t-hejconduit 26 and the ventilating head23 of such character-that the former may be temporarily moved from obstructing position. The sleeve 25 has a swivelling engagement-with the coned head 23 on the standard 12.; In order to prevent leakage at this swivel joint, which might undesirably afiect theventilation system, I provide a locking ring 28, upon the plane.
30. projectinglf rom neck 3l of the M 341 and its Sleeve y then be freely swun around by the operative, by means of the handle 33, until it out of .obstruetjng position. Upon the return of the conduit .to its normal position, the handle ofthe locking ring 28 is rotated in re'VerSe direction, and thecam faces 29 of the ring, riding the fixed 'studs 30, lift the ring and thus the s'leeve25 into close engagement with the ventilating head 23; The joint between these parts is thus sealed and the position of the conduit above the topof the melting pot is maintained regardless of the'viloltiitions to which the machine is Subjected dun ing its operation.
If it be desired to regulate the pull of the exhaust fan in each ventilating fine, this may be readily accomplished byarnanging da pers .34 and n t e St ndard 2 nd in" the conduit 26. The adjusted position of these dampersmay be fixed by set screws 36 passing through arcuate slots in segrnents 37 at the jouter ends of the damper spindles 3.8. It may be pointed out that the set screws serve to hold theldamper spindles in position, as well as fixing the. angular position of the damper It may be also pointed outv that the damper itself may be introducedthrough one of the oval shaped ports 24 in the ventilating head afterfthe sleeve hasbeen removed a'nd without'necessitating a complete dismantling of 'the' installation to effect. this repairf VVhile I have shown a construction i which the pot 6 is, heated by gas, it 'is also of value where the melting is accomplished by electricity. In the latter case, of-c ourse, the standard 12 may be solid I have also provided a hook 39 on the neck of the ventilating head forthe purpose of remOvahly supporting a'thermon 'e'ter 40. The hook is of course 'so located that the thermometer, when supported thereon, dips at its lower end'into the molten lnetal'in the pot. The operative isthus able to ascertain atany' time the heat of the metal, and be sure that it is in proper working condition This a Pract f a ur o gre mpe means he properqpe 10f theas n meamsmis l n n HP heiardi fa ra ge and "modification and cbn'str ione pare iv l may o cu t hose deal with the subject; without departing" from Wha I ,cla m lyii nt bn-j he cqmbina o wit ype-me l melting pot, of a tandard snppor t'ed thereon and arr nged at onefside of thepotg a Vent 'lat'ing' head on said standard, a collecting conduit swivelling on said head and extending there from over the pot to collect the fumes rising therefrom, and means at the swivel joint holding said conduit in fixed p s ion over the pot,
