SPECIFICATION forming part of Letter sPatent No. 678,113, dated J uly 9, 1901. Application filed October 27, 1900. Serial No. 34,617. (No model.)
To ctZZ whom it may concern.-
Be itknown that I, JOHN Q. EVERSON, a citizen of the United Stat-es, residing at Pittsbnrg, in the county of Allegheny, State of Patent of the United States No. 325,791, dated September 8, 1885. In the use of the apparatus illustrated and described in said Letters Patent it was impossible in many instances-as, for instance, in non-return flueboilersto prevent the force of the steam discharged into the fines from forcing the products of combustion, and in some cases the fuel itself, out of the furnace-door.
My present improvement is for the purpose of reducing the steam-pressure before admis-- sion to the fines to avoid this difficulty; and to this purpose it consists in the novel construction and arrangement of parts hereinafter specifically described and claimed, reference being had to the accompanying drawings, in which- Figure 1 indicates a longitudinal section of a fined steam-boiler with my improvement applied thereto. Fig. 2 is a front elevation of the same. Fig. 3 is a modified form of my present improvement. I
In describing my present improvement and its mode of operation I will describe so much of my former improvement as will enable a proper understanding of the present invention.
Referring to the drawings, 1 is a fined steam-boiler having a safety-valve 2 connected with the steam-drum 3 thereof. A horizontal piped is connected with the safetyvalve and enters the stack 5. The continuation or vertical member of said pipe his projected downwardly of the stack and isconnected to a transverse pipe 6, the said trans- Verse pipe having a number of short horizontal branches 7, which enterthe fire-fines of said boiler. The vertical member of the pipe 4 is provided with a number of perforations or holes a. for the purpose of permitting the steam to be discharged in advance of its discharge into the fire-fines of the boiler for the purpose of lessening or decreasing the force of the steam, and thus preventing the pressure of the steam blowing or forcing the fuel or products of combustion through the door of the furnace. v
In Fig. 3 I have shown a modified form of my present improvement, which comprises a branch pipe 8, which is connected to the pipe 4f and enters the stack at at, the opening in said pipe 8 being controlled by a valve 10.
Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-- having fire flues and a safety-valve of a pipe connected at one end with the opening controlled by said valve and provided with branch pipes at the other locatedwith refercharge steam into the outlet ends of said fire fines, and means for lessening or decreasing the pressnreof-the steam in advance of its discharge into the fire-fines of the boiler, substantially as described. i
2.' The combination with a steam-boiler having fire-fines and a safety-valve of a pipe connected at oneendwith the opening controlled by said valve and having branch pipes located so as to discharge steam into the out 1. The combination with a steam-boiler let ends of the fire-fines of said boiler, the,
said pipe being provided w ith"one or more perforations at a point between the safetyvalve and said branch pipes, substantially as described. I In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. JOHN Q. EVERSON.
