UNITED STATES DAVID SAUNDERS, OF BROOKLYN, ASSIGNOR TO JOSEPH NASON 8:. COMPANY,
OF NEW YORK, N. Y.
IMPROVEMENT IN SUPERHEATED-STEAM ALARMS.
Specification forming part of Letters Patent No. 132,863, dated November 5, 1872.
To all whom it may concern:
Be it known that I, DAVID SAUNDERS, of Brooklyn, in the county of Kings and State of New York, have invented a certain Improved Boiler Attachment for limiting the temperature of steam, of which the following is a specification:
The object of this invention is to provide a sure and efficient guard against steam leaving the generator or boiler at a temperature above that corresponding to the pressure which may be deemed safe and proper. The invention is intended more particularly to be applied to boilers used in the warming of buildings, but it may advantageously be used when it is desirable, for any purpose, to regulate and limit the temperature.
The following is a description of what I consider a simple and suitable means of carrying out the invention. The form of the parts may be modified in various ways.
The accompanying drawing forms a part of this specification, and is a vertical section through the apparatus as attached to a boiler.
A is a boiler to which the safety apparatus is applied. B is a strong vessel, of east-iron or other suitable material, provided with means for filling it with water and for discharging the same. It is also providedwit-h a safety-valve, D, and with a steam-whistle, E. There may also be a steam-gage attached, as indicated by F. O is the steam-pipe leading from the boiler, and G is a continuation thereof, which passes through the vessel B, and is constructed with convolutions so as to augment the surface. G is the safety-valve for the boiler, and C is a further continuation of the steam-pipe, conducting the steam to wherever it may be requiredfor use.
In order to prevent, as far as possible, the loss of heat by radiation, the exterior surface of the whole apparatus, including the parts of the pipe O and (3 should be covered with felt or other non-conductin g material; but the coiled part at G is adapted and intended to give off any excess of heat as freely as possible to the water within the vessel B.
The operation of the apparatus is as described below: After properly filling the boiler A with water, and also filling the vessel B, fire may be made. As soon as steam begins to be made in the boiler A it will rise in the pipe 0 G and transmit its heat through the metal of the pipe 0 O to the water in the vessel B until the temperature in the boiler A and the vessel B is alike, and until the desired pressure is consequently attained. Until'the water in the vessel B has risen to the temperature of the steam in the boiler A some condensation will be going on in the coil O G the water of which will return by its gravity to the boiler A.
Under ordinary conditions the steam will not be affected by its passage through the coil 0 O as the steam and the water in the boiler A, and also the water in the vessel B, will all be equal in temperature; but should the steam become superheated it will, in its passage through the coil 0 0 give off its excess of heat to the water in the vessel B, which will beat arelatively low temperature. Should the superheatin g continue, a pressure beyond that in the boiler A will be produced in the vessel B, to which the safety-valve D will respond, and the alarm will be sounded by the whistle E. The apparatus will, in this way, prevent the passage of superheated steam to the pipe or radiator, and will at the same time announce its presence in the boiler.
I claim as my invention- The combination of the alarm apparatus D E with the casing B and pipes (J 0 C arranged, as specified, so that the water in the casing B serves to regulate and equalize and limit the temperature of the steam passing through it, and also to give an alarm when the desired limit is exceeded, all substantially as herein specified.
In testimony whereof I have hereunto set my hand this 7th day of June, 1872, in the presence of two subscribing witnesses.
D. SAUNDERS.
