SHUTTER FOR GAS-STOVE BURNERS.
Specification of Letters Patent.
Patented Jan. 19,1915.
Application tiled May 9, 1913. Serial No. 766,645.
To all vu-i o m. l1 t muy concern Be it known that I, MINARD A. Possoxs, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio.A have invented certain new and useful Improvements in Shutters for (las-Stove Burners, ot' which the following is a specification, reference being had tlieiein to the accompanying drawing.
My invention relates to improvements in shutters for gas stove burners.
The object of my invention is to provide a shutter for a gas-stove burner which can be readily adjusted to vary the amount of air supplied to the burner without removing the securing screw, as has heretofore been the case in shutters of this kind.
Another object of my invention is to provide a simple, cheap and more effective shutter and means for holding it in its adjusted position, and having certain details of strueture hereinafter more fully described.
In the accompanying drawings; Figure 1 is a perspective view of the end of the mixing tube o'f a biii'iier showing my shutter applied thereto. I"ig. 2 is a vertical loiigitudinal sectional view showing the shutter in dotted lines in the act of being adjusted. Fig. 3 is a rear perspective view ot the shutter looking.r in the opposite direction to that shown in Fig. 1.
Referring now to the drawings, 1 represents the mixing tube which leads to the burner and which has at its outer end an enlarged mixing chamber 2, provided at its outer end with the transverse plate or web 25. having openings 4 therein, which aie adapted to register with the openings 5,6, and 7. in the shutter 8. This transverse plate is provided with a screw-threaded opening 9. into which the screw 10 is adapted to be screwed. The shutter 8, as shown, is provided with a central opening il, having an inwardly extending flange 11', through which the gas supply injecting nozzle passes, as is well understood by those skilled in the art. This iaiige, as will be seen, forms a support for the injecting nozzle. The said shutter is made of a diskshape having at its periphery an inwardly extending fiange 12, which is adapted to snugly fit the outer periphery of the outer edge of the mixing chamber 2. 'The diskshaped portion of the shutter is provided with a segmental opening 13, through which thc screw 10 passes, and by means o'f which the shutter is supported on the outer end of the mixing tube. The segmental slot 123 allows of the ready oscillation of the shutter or the mixing tube. The inwardly extending flange of the shutter is provided with a series ot' notches I4, which are adapted to receive a stud 15, carried by the. periphery of the mixing chamber Q. rI`here are a series of these openings, as clearly shown in Fig. 3 of the drawing, which allow of a large adjustment of the shutter on the mixing tube.
By turning the shutter on the mixing tube, it will be seen that the openings (i and 7 can be brought to gradually or wholly register with the openings iii the transverse plate, whereby a greater oi less amount ot' air is allowed to pass into the mixing chainber. The adjustment of the shutter is allowed by turning the screw one revolution or a little over, which allows the outward movement of the shutter. and allowing it to tilt, as shown in Fig. 2 of the drawings. to bring the nftclies 14 out of engagement with the stud l5, carried by the mixing tube. whereby the shutter is adjusted to admit the desired amount of aii to the mixing chainber. This structure, as will be seen. allows of a positive locking of the shutter without removing the screw, as is the case of shutters of this character now employed on burners.
Having thus described mv invention. what I claim and desire to secilre by Letters Iatent is:
1. In a burner the combination of" a mixing tube. a shutter extending across the end of the mixing tube and having openings, means for holding thc shutter tothe mixing tube. a stud carried by the tube and notches carried bv the shutter and cooperating with the stud carried bv the mixing tube.
2. ln a burner the combination oi a mixing tube. a shutter closing the end of the mixing tube. and a setscrew for holding the shutter to the cnd of the mixing tube and allowing the same to oscillate, said shutter and mixing tube having cooperating notches and stud.
3. In a burner the combination oi a mixlng tube. a shutter closing the end oic thc mixing tube and having a segmental slot and having an inwardly extending flange surrounding the outer end of the mixing tube and having a series of notches, a stud carried by the mixing tube and adapted to enter said notches, and a screw passing through the segmental slot in the shutter and screwed into the mixing tube.
4. In a burner the combination of a mixing tube having openin s in its end, a shutter closing the end of tie mixing tube and having a series of openings registering with the openings in the end of the mixing tube and a se ental slot, said shutter having a circular ange surrounding the mixin tube and vhaving a series of notches, a stu carried by the mixing tube and adapted to enter said notches, and a screw passing through the segmental slot in the shutter and screwed into the mixing tube.
5. In a burner the combination of a mixing tube, a web carried by the outer end of the mixing tube forming segmental slots, a shutter extending across 'the end of the tube and having slots registerin with the slots in the web, said shutter having a central oil receiving nozzle opening, an inwardly extendingcircu ar flange surroundin the periphery of the shutter and snugly fitting the end of the mixing tube and having a series of notches, a stud carried by the mixing tube and entering said notches, said shutter having a segmental slot and a set-screw passing through said segmental slot in the vshutter and screwed into the web of the mixing tube, whereby the loosening of the screw allows the shutter to tilt upon the mixing .tube to bring the notches out of engagement vitlcil the stud, whereby the shutter is oscilate 6. The combination with a mixing tube, of a plate extendin across the outer end of the mixing tube an havin openings to admit air to the tube, a s utter extending across the end of the mixing tube and having openings registering with the openings in the plate an a central opening havin an inwardly extending fiange to receive ang support the gas-injecting nozzle, the outer periphery of said shutter having an inwardly extending circular (lange snugly fittinar the outer periphery of the mixing tube andj having a series of notches therein, a stud carried by thc mixing tube and adapted to enter said notches, said shutter having a segmental slot concentric with the central nozzle receiving opening, and a screw passing through said segmental slot and screwed into the plate carried by the end of the mixing tube.
7. In a burner the combination of a mixing tube, a shutter extending across the end of the mixing tube and having openings, means passing through the shutter for holding the shutter to the mixing tube, and a separate means carried by the side of the mixing tube for locking the shut-ter in its adjusted position.
8. In a burner the combination of a mixing tube, a shutter extending across the end of the mixing tube and having openings. means for holding the shutter to the mixing tube, and cooperating notches and stud carried by the mixing tube and shutter for locking the shutter in its adjusted position.
9. In a burner the combination of a mixing tube, a shutter therefor, means for holding the shutter to the mixing tube, notches carried by the shutter, and a stud carried by the mixing tube. said notches cooperating with said stud and holding the shutter in an adjusted position.
10. In a burner, the combination with a mixing tube, of' a shutter therefor, means for holding the shutter to the mixing tube, and cooperating stud and notches carried by the tube and shutter for holding the shutter in its adjusted position.
In testimony whereof I hereunto ailix my signature in the presence of two witnesses.
