SIGNAL FOR BOILERS Filed March 29, 1933 Attorneys Patented Jan. 16, 1934 UNITED STATES PATENT OFFICE SIGNAL FOR BOILERS Antonio J. Meneghetti, Montreal, Quebec, Canada Application March 29, 1933. Serial No. 663,254
1 Claim.
The present invention relates to a signal attachment particularly adapted for domestic boiling vessels and the like.
An important object of the invention is the 5 provision of an attachment for boilers whereby an audible signal will be produced when the contents of the boiler have attained a boiling temperature.
A further object of the invention is the provil sion of an audible signal attachment for boilers which may be easily removed for cleaning.
Another object of the invention is the provision of a signal attachment for boiling vessels which will produce an audible signalling eiiect u when the contents start to boil and which will continue during the continuation of the boiling action.
Still another object of the invention is the provision of a signal attachment of the above 30 character having means co-operatively associated therewith for reducing or eliminating thesignalling sound.
A still further object of the invention is the provision of signalling means of the above character which will be very simple and durable in construction and which can be attached to a boiling vessel at a very low cost.
Other objects and advantages of the invention will become apparent as the description pro- 4,30 gresses.
In the accompanying drawing forming a part of this specication and in which like reference characters are employed to designate corresponding parts throughout the same:
- Figure 1 is a top perspective view oi a boiler cover showing the improved attachment associated therewith,
Figure 2 is a central diametrcal section through the cover and signal devices,
40 Figure 3 is a fragmentary bottom plan view i159 the signal, and
Figure 7 is a similar view showing the adjustment for eliminating the signal action.
Referring to the drawing, wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 10 generally designates a conventional form of domestic boiler, in the form of a pot or kettel open at the top, and normally supporting on the top edge a removable cover 11.
The cover 11, in the present instance shown of circular form, is shaped so that its main centrai portion is of concavo-convex transverse curvature, so as to assume an outwardly bulging position when disposed on the kettle. Adjacent the peripheral edge the cover is provided with a -55 circular, relatively small, opening 12. At a diametrically opposed position the cover is provided with a plurality of closely disposed openings 13.
To the underside of the cover is adapted to 79 be connected a signal member 15 preferably in the form of a relatively thin metallic disc of concavo-convex curvature provided with a central opening 16. Attached to the cover and projecting downwardly therefrom at approximately uniformly spaced positions are a plurality of pins 17 provided with notches 18. The signal disc 15 is to be removably secured in position against the cover by means of an approximately circular metallic ring 19 of resilient construction. 130 When operatively associated with the cover, the peripheral margin of the disc 15 is disposed against the underside thereof and the ring 19 is disposed about the exterior margin, the ring being formed to expand into the notches 1S of '8 the pins 17 to rigidly hold the disc in position. When thus connected, the opening 16 will be disposed in registration with and spaced from the opening 12 of the cover, as shown to advantage at Figure 2.
On the top of the cover is pivotally fastened a segmental, preferably metallic, plate 21 arranged so that it may be disposed in a position to cover the openings 13 or swung to one side to uncover one or all of these openings.
During use of the device, the cover member 21 is adjusted to a closing position, that is to a position covering the openings 13, when the contents of the boiling kettle are initially subjected to heat, as for instance a gas burner, 10U as shown at Figure 6. When the contents of the kettle are heated to the boiling point, the steam generated therein and escaping through the outlets 12 and 16, and passing through the chamber formed between the disc 15 and the cover, will produce a whistling sound which will continue as long as the boiling operation is maintained. To discontinue the operation of the signailing whistle, it is merely necessary to pivotally adjust the plate 21 so as to uncover one or 1310 more of the openings 13, providing an additional outlet for the steam.
Thus, the present device affords means whereby the cook or chef, when cooking food or other commodities in a boiler, will be automatically informed when the contents of the vessel begin to boil, obviating the necessity of frequently attending the vessel to determine the initiation of the boiling action and enabling the diversion of his attention to other duties.
It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same, and that various changes as to the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim;
Having thus described my invention, I claim:-
The combination with a boiler cover having a plurality of apertures therein, of a movable cover plate secured on the boiler cover adapted to normally close one of the apertures in the cover and movable to open the said aperture, an arcuately bulging member tted against the inner side of the cover, the said arcuately bulging member being provided with a central opening disposed to assume a position opposite another aperture in the cover, and a resilient member adapted to engage projections on the boiler cover for removably securing the bulging member against the said boiler cover.
ANTONIO J. MENEGHETTI.
