WALL-BOX EXTENSION SLEEVE.
Application led. September 11, 1922. Serial No. 587,532.
To @'17, ywhom t may con/cern.'
Be it known that I, CLAnnNon C. SHUT, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and useful Improvements in iall-Box Extension Sleeves. of which the following is a specification.
In wall-box ventilators for houses, an extension-sleeve completes the air-passage between the wall-box and the adjacent wall of the room, and for a good workman-like job the inner edges of the sleeve should be eX- actly flush with the inner surface of the plastered wall through which it passes. This, however, is diiiicult of accomplishment in practice because of the variations in thickness of the wall, and of the plastering on the wall, and after long years of experimenting to overcome this annoyance I have solved the difficulty by the use of a second sleeve with the wall-box extension sleeve, telescopically adjustable relative to the latter, and adapted to be held rigidly in a given position by means that can be quickly withdrawn, without disturbing the position of the second sleeve, to present an unobstructed air-passage.
In the accompanying drawings illustrative of my invention, Fig, 1 is a front elevation, detached from a wall-box extension sleeve. Fig. 2 is an end view of same showing the bracing means`v in dotted lines in a position partially withdrawn, Fig. i is a vertical. section on the line 4 4: of Fig. 1, and Fig.y 8 is a vertical section of a wall, a wall-box, and a wall-boxv extension sleeve with my invention applied in working position.
Referring to Fig. 3, the Ventilating wallbox 5, generally made of cast iron, has the usual storm louvers 6, insect screen 7, and air-damper 8, which do not form any of the novel features of my invention.
The wall-box 5 is easiest built into the wall 9 as the wall is laid. It has a wall-box extension sleeve'lO, enough lower than the top of the box to provide a space to receive a two by four inch wooden nailing-strip 11. The mouth of the sleeve 10 is temporarily closed by a wooden board 12, the purpose of which is to keep the otherwise unsupported edges of the sheet metal sleeve from being bent and damaged during the erection of the building and the placing of its equipment.
My invention comprises the telescoping with sleeve 10, of a sheet metal sleeve 13, that can be adjusted so its edge toward the room will be exactly fiush with the inner plastered surface of the wall, and in practice the sleeve 13 will be set so its inner edge will form part of the grounds for the plasterer to work to.
'Ihe wooden nailing-strip 11 is placed upon the sleeve 13 with the inner edge flush with the adjacent edge of the sleeve where it will be ready to nail the top flange of the adjustable box base connection 14 to.
In order to protect the edge of the sleeve 13, and support it during the erection and equipment of the building, a reinforcing board is fitted snugly in the mouth of said sleeve. This may be solid, or it may be built up, but it will be preferably comprised of two horizontally joined boards 16 and 17, hinged at their joint to open into the room, and provided with an eye-pull 1 8 near the joint. The boards are appropriately provided with edge-pins 20, at top and bottom, that pass through suitable holes for that purpose provided in the top and bottom members of the sleeve 13.
When the two members, 16 and 17, are swung into vertical alignment a strong toggle action is developed to hold the edge of the sleeve, and the engagement of pins 2O with the sleeve will prevent accidental displacement of the board. However. it can be readily withdrawn by a pull on the eye 18.
I-Iaving thus fully described my invention, what I claim as new and wish to secure by Letters Patent, is-
1. 'The combination, with a four-sided sheet-metal Ventilating sleeve, rectangular in cross section, of a removable means for simultaneously supporting and protecting the edges of the sleeve, comprising a complete closure contacting all four edges of the sleeve when in operative position, said closure being in a plurality of parts capable of angular displacement relative to each other for removal. l
2. A removable means for simultaneously supporting all of the edges of a foursided sheet-metal ventilating sleeve comprising a complete closure in a plurality of parts capable of angular displacement relativeto each other for removal, said means having marginal sleeve-engaging devices.
23, A reiiiovzibie means 'for supporting all pine in the low zuid bottom edges of the tvoof the edges of a four-sided sheet-metal part member cooperating with holes in the. Ventilating Sleeve comprising a two-part sleeve. 10 member having the parte hinged together Signed at Indianapolis, Indiana, (this 8th and completely closing the sleeve-interior day of September, 1922. when in operative positions Jherein and supporting all of the edges of the sleeve, and CLARENCE C.
