VENTILATOR 'rnmiisnn Application led July 3, 1928 Serial No. 290,226.

My invention relates to registers and register thimble structures adapted to afford a controllable passage through a partition, such as a wall, or more especially, through a ceiling and the floor above it, so as to ventilate or heat a room by air passing through the register from the room below.

A principal object is to so construct these registers, and especially the thnnble structures as to simplify and reduce the cost of labor in installing them, and more especially to provide an arrangement of parts by which installation may be made quickly and easlly by one workman. g A further object is to improve the structure of registers of the stated class in various ways, as pointed out below.

The characteristics and advantages of the invention are further suiiiciently explained in connection with the following detail description of the accompanying drawing, whichY shows one preferred embodiment. After considering this example, skilled persons will understand that many variations may be made,

and I contemplate the employment of any structures that are properly within the scope of the appended claim. Y

In the drawings: Fig. 1 is a perspective view of a register, so embodying the invention in one form, in operative position, with some parts broken away, for explanatory purposes.

Fig. 2 is a section at 2-2, of Fig. 1. Fig. 3 is a top plan of the ceiling screen id, with its connected sleeve. ig. 4 is a. side elevation, with the principal parts in separate condition.

In the adaptation shown, the complete register is arranged as a controllable flue between an upper and a lower room, and 1ncludes as principal parts a register proper, R, and a thimble structure including a ceiling screen or grid G with its connected sleeve D, and an adjustable or telescoping sleeve structure S. Register R may be provided with any suitable movable slide or vanes, located below the top-plate or grid 1, and maybe operated by any suitable means such as a knob or lug 2, to control the effective area of air-passage, and has its marginal portions arranged as a flange 3 overlying a flanges, which projects laterally at the top of a sleeve section 5, which forms the vupper half of the v sleeve structure S. The lower section 6 of this sleeve structure telescopes within the upper section, its downward movement-being limited by cooperating lips 'Tand 8.

Sleeve D has at itslower end a flange 10 to engage the ceiling surface, and the periphery V1l vof screen G engages this iiange. rlhe 60 sleeve and screen are connected by anglestrips 12` andV screws 13. At the sides of sleeve D, neariiange 10, are spring loops 14,

to receive the hooked lower ends of springs 15. These loops lare desirably formed by slitting and pressing the sheetmetal walls. The register is. installed in the superposed apertures A of the floor F and ceiling C, by a workman stationed on floor F, without necessity for a helper working below the ceil- 170 ing, in the following manner:

Nails 20 are driven in the sides of the floor opening A, to receive the upper ends of springs 15. The connected sleeve D and ceiling C, (separated from the rest of the struc- Y ture) are then tilted and turned to such position that they may be passed down through the apertures, and flange l0 ris positioned against the ceiling surface, and is then easily held in position by one hand of the workman while the upper ends of the springs are engaged with the nails. Thesprings are of such length that when stretched and connected in the manner shown, they securely retain the lower sleeve-and-screen structure in position. This mode of support provides for all reasonable variations in floor and ceiling spacing without requiring any complicated, adjustable supporting devices.

The sleevestructure S is then put in place in a way which is obvious from Figs. 1 and 2, with flange 4 resting on the floor surface, and with sleeve D telescoping in sleeve sec-- tion 6; and the latter may drop down until 95 its lower edge rests on flange 10, or until checked by engagement of lips 7 and 8, thus completing the tubular lining of the aperture, with practically automatic adjustment to the vertical dimension thereof. Register 100 R is then placed, as also shown in Figs. 1 and 2, and may be secured as by screws 25.

I claim:

In a Ventilating thimble adapted to be positioned in an opening between the floor of an upper room and the ceiling of a lower room, thel combination of telescoping lower, intermediate, and upper sleeves of progressively increasing diameter, said intermediate and upper sleeves being provided with eooperating lips for permittingorelative telescoping movement but preventing complete separation from each other, said upper and lower sleeves being providedwith flanges :torl

engaging respectively the edges of the openings in said floor and ceiling, spring means positioned exterior of the thimble and attached to the lower sleeve and to the edge of the floor opening to support said lower sleeve directly from said floor and to resiliently maintain said lower sleeve with its flange against the lower edgeof said ceiling open-y ing, permitting said upper and intermediate sleeves to be placed in telescoping engagement with said lower sleeve after positioning said spring-means-supported lower sleeve in said ceiling opening and for permitting maximum inward collapsing telescoping movement of said upper, intermediate and lower sleeves. f l

In testimony whereof I afix my signature.

JOSEPH V. PETRELLI.
