[44 i4 QM G. A. PORTER.
STEAM BOILER.
Patented Dec. 22, 1885;
UNITED STATES PATENT OFFICE.
GEORGE A. PORTER, OF SYRACUSE, NEW YORK.
STEAM-BOILER.
SPECIFICATION forming part of Letters Patent No. 332,828, dated December 22, 1885.
Application filed September 21, 1885. Serial No. 177, 685. (No model.)
To aZZ whom it may concern:
Be it known that I, GEORGE A. PORTER, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Steam-Boilers, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.
This invention relates to the boiler for which I have obtained Letters Patent of the United States No. 325,967, dated September 8,1885. In said boiler I have maintained the boiler-shell of uniform diameter to the edge of its rear end and deflected. the bottom portion of the smoke-box shell from the boilershell, for the purpose of obtaining room for a hand-hole through the deflected end portion of the smoke-box shell.
It will be observed that in a boiler constructed as aforesaid the hand-hole is back of and covered by the end cover of the smokebox, and therefore said hand-hole is inaccessible except when the aforesaid cover is removed.
The object of my present invention is to form only a single seam between the boilershell and smoke-box shell, and yet render the hand-hole accessible without the expenditure of time and labor required to first remove the end cover of the smoke-box; and its object is also to reduce the circumference of the seam at the junction of the boiler-shell and smoke-box shell, and thus accomplish a saving in the number of rivets and time of riveting required for joining said shells; and to that end my invention consists in the novel construction and combination of parts hereinafter fully described, and specifically pointed out in the claim.
In the annexed drawings, Figure I is a longitudinal section of a steam-boiler embodying my improvements, and Fig. II illustrates modifications of the same.
A represents the main shell of the boiler. O is the smoke-box, surrounded by a water and steam space, a, formed by an extension, A, of the boiler-shell beyond the flue-sheet a, to which latter" the smoke-box shell 0 is attached. The boiler-shell extension A is of the same circumference as the main shell A, and the flue-sheet a and smoke-box shell (3 are both of a smaller circumference than the boiler-shell extension A, and thus form the space 0 around the smoke-box. The end of the shell A, I bend inward, so as to contract the circumference thereof and cause it to embrace the end of the smoke-box shell, the shell A terminating with an outward flange, by which it is riveted to the smokebox shell. the shell A, below the end of the smoke-box, I form a hand-hole, I), through which to clean the water-space a. The smoke-box cover B being applied to the joined edges of the shells A and O leaves the hand-hole b exposed and convenient of access when necessary.
'In bollers having a deep water-space, c, the end of the smoke-box shell may be bent partly outward to meet the inwardly-bent end of the shell A, as shown in Fig. II of the drawings.
I am aware that prior to my present invention a steam and water space has been formed around the smoke-box of the boiler by an extension of the boiler-shell around the smoke-box shell, and an end plate secured to said shells; but such a construction produces two seams, while by my improvement only a single seam of minimum circumference is formed. Consequently said prior construction entails more than double the expense in time, labor, and rivets required for forming the end of the steam and water space around the smoke-box.
Having described my invention,whatI claim as new, and desire to secure by Letters Patent, 1s-
In combination with the smoke-box shell 0, the boiler-shell extension A, formed with the steam and water space 0 between it and the shell O, and having its end bent inward and terminated with an outward flange embracing the end of the smoke-box shell, and riveted directly thereto, substantially as described and shown.
In testimony whereof I have hereunto signed my name and affixed my seal, in the presence of two attesting witnesses,- at Syracuse, in the county of Onondaga, in the State of New York, this 19th day of September, 1885.
GEORGE A. PORTER. [L. s.]
