To all whom t may concern:

' Be itv `known that I, CHARLES O. Wnsoor'r, citizen of the UnitedV States, residing at Tacoma, in the county of Piercerand State of W'ashington, have invented certain new and useful Improvements in Stud-Supports; and I vdo hereby declare the lfollowing to be and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to the accompanying drawings, and to letters 'l or figures of reference marked thereon,

which form a part of this specification.

This invention relates to means for securing the arch supporting stud used in fire boxes, and has for its primary object the provision of efficient means for supporting and retaining brick studs.`

The object ofthis .invention is provide,V

retaining means for a brick stud of the character set forth, which shall be so con- .structed as to facilitatethe removal of the brick stud after the same has been burned out.

A further object of this invention is to provide a brick stud retaining means s o constructed as to permit the removal of a burnedout brick stud, while the rboiler is under pressure.

vA still further object of this invention is to provide a brick stud retaining means :which shall be unaected by heat and veasy to install in a position upon the ire box wall.

Vith these andother objects in view, this invention consists in the peculiar combination and arrangement of the various parts of a brick stud retaining means as hereinafter described and more particularly set forth in the appended claims.

Referring to the drawings wherein similar reference characters indicate similar parts wherever used: Figure 1 is a section through a iire box wall showing the retaining means in place, and F ig. 2 is a detail side elevation` of the brick stud and supportparts shown in separated relation.

3 designates a fire box wall, and 4, the outside boiler wall, secured together in the usual manner rby means of a Vstay bolt 5. The lire box wall 3 is provided with a threaded opening 6, into which is adapted to be inserted a screw. threaded member 7,

formed upon the outside with threads 8 and similarly threaded internally at 9, and provided with an internal v concave end l0.

Specification of Letters Patent.

Adapted to'fit the concave portion 1() of themember 7 ,is a small brass or other suitable metal block 11.v :A second member 12 externally threaded at 13 and internally lthreaded at 14 and preferably made' of'brass or'any other suitable heat resisting metal is then screwed" intor the member 7, the outside threads 13 of the member 12Uengaging the internal threads 9 vof the member 7 until stopped by the fiat face of the block 11. An ordinary type of brick stud 15 provided with a threaded end 16 is then inserted, within the member 12, the threaded end 16 of the stud 15 engaging the internal' threads 14 of (the member 412. The y stud is then yin posi- ,tion to support the lire-brick 17 in the usual manner. Y

Due to the construction above described,

it will be seen'that whenthe intense heat of the fire boxhasl burned out thestud 15, it'may be unscrewed from `the member 12 without necessitating the removal of the member 7, which thereforeenables the brick Y stud to be removed while the boiler is underpressure, the member 7 forming an effective1 closure for the opening in the lirey box wal f The member 12 being formed of brass or any other suitable heat resisting material,

will retain underthe most trying conditions area of the member 7 and will therefore, at

its travel in the configurationV and threaded all times, present aproper support for av brick stud, and will be effectively retained by the member 7 I realize that considerable variation of the specific y'details of constructionV illustrated and describedherein ymay be resorted to without departing from the spirit of my f nternally threaded and adapted to be in- IOO cure by United yStates Letters Patent, is zl serted in a fire box wall, a second cylinf drical member externally and internally threaded, the externalthreads of which are adapted to. engage thevinternal threads of said first mentioned member and the internall threads of which are adapted to receive the threaded ends ofia brick supporting stud,

and a heat resisting metallic bloel forming a stop for the further insertion of said second member and said stud.

2. In a ire boX, the combination With a fire boX Wall provided With a threaded opening therethrough, of a cylindrical member closed at its inner end and externally and internally threaded and adapted to engage the threaded opening ,in the fire box Wall, a second cylindrical member externally and internally threaded, the external threads of Which are adapted to engage the internal threads of said first mentioned member, a heat resisting metallic block in the closed end of said supporting member and adapted 15 to form a stop for the further insertion of said second member, a stud having a threaded portion adapted to engage the internal threads of said second mentioned member whereby to supportthe stud.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
