BOILER-BRACE COUPLING.
Specification of Letters Patent.
Patented May 16, 191
Application filed November 20, 1915. Serial No. 62,537.
To all whom it may concern Be it known that I, SYLvns'rnn U. WALOK, a citizen of the United States, residing at Lansford, in the county of Carbon and State of Pennsylvania, have invented certain new and useful Improvements in Boiler- Brace Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.
This invention relates to new and useful improvements in boiler brace couplings and consists of a simple and efiicient apparatus of this nature having various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claim.
My invention is illustrated in the accompanying drawings, in which:
Figure 1 is a central vertical sectional view through a portion of the boiler showing the application of my invention thereto. Fig. 2 is a detail sectional view of the head of brace. Figs. 3, l and 5 are detail perspective views of parts disassembled.
Reference now being had to the details of the drawings by letter, A designates the back head of a boiler and B the wrapper sheet. 'A brace, designated by letter C, is held by rivets D to the wrapper sheet and the back head is provided with an opening interiorly threaded, adapted to receive the threaded portion of the shell E, which threaded portion of the latter is upon a tapering circumference. The inner end of said shell has a tapering opening, as shown in the drawings, and through which the end of the brace C is adapted to pass. The outer portion of said shell is chambered and having a concaved seat as shown about the opening therein and is interiorly threaded for the reception of the cap F, which latter is concaved as shown and provided with a recess H in its outer face for the reception of a wrench. A nut K, having one face convexed, is mounted upon the threaded portion of the brace C and has a portion of its circumference angular outlined for the reception of a wrench, said concaved surface of the nut being adapted to have a bearing against the concaved surface of the chambered portion of the shell E, as shown.
In applying the brace and coupling, the inner ends of the braces are securely held to the wrapper sheet by riveting or otherwise and the threaded portion of the brace is passed through the shell E. The nut is turned upon the brace so that a few of the threads will project beyond the nut and which projecting threads are riveted or battered over the end of the nut which will tend to hold the nut firm and prevent it from coming off or working loose. The cap is then screwed into the shell inclosing the nut in the manner shown.
In the event of it being desired to inspect the braces, the cap may be removed by a wrench inserted in the socket in the end and, in the event of the brace and nut turning together, it will be evidence that the brace is broken, the broken portion of the brace being adapted to be withdrawn with the nut from the boiler. A socket wrench could then be applied to the shell, removing the same from the boiler.
In order to remove the part of the brace which is riveted to the boiler sheet, the rivets holding the same may be cut, allowing the inner portion of the brace to be readily removed. After the brace isremoved, it may be slipped into the boiler through the opening in the end of the boiler head. The inner end of the brace may be drawn up to the wrapper sheet, holes tapped and screw plugs fitted into the wrapper sheet and brace, allowing the plugs to extend above the sheet for a distance of a few threads which may be afterward riveted over the same as a stay bolt, thus making a tight oint, after which the shell may be screwed into the boiler head and the parts replaced, as will be readily understood.
What I claim to be new is A boiler head coupling comprising in combination with a boiler having a threaded aperture in a wall thereof, a shell circumferentially threaded and engaging said aperture, the opening in the inner end of said shell being flared and the said shell being chambered and provided with a concaved seat, a cap threaded into said shell and concaved, a nut having its inner face convexed In testimony whereof I hereunto afiix my and engaging saiddseat, anddha bar threarllled signature in presence of two Witnesses.
