BUILDING-BLOCK.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed October 16, 1905. Serial No. 283,071.

To all w/wm it may concern.-

Be it known that we, EDWARD J AMEs Mo- ELLIGOTT and EDv RDo A. CIMMERY, citi- Zens of the United States, residing at Manistee, in the county of Manistee and State 01 Michigan, have invented certain new and useful Improvements in BuildingBlocks, of which the following is a specification.

This invention has for its object to provide a building-block of novel construction which may be incorporated in a hollow wall construction to secure ventilation thereof.

The invention consists of a building-block of cement or other material generally used or adapted for use in the manufacture of blocks to be built into a wall or like structure. The block is hollow and designed to be set into a wall so that a series of said blocks will form a continuous passage in a vertical direction for the circulation of a current of air. Certain of the blocks will be provided in a side with a ventilator having protected dampercontrolled openings to exclude the passage of mice and vermin and admit of the current of air being regulated.

A wall constructed in accordance with this invention is dry upon the inside and practically proof against the passage of frost and dampness.

The invention consists, essentially, of a hollow building-block having a ventilator in a side thereof, said ventilator being prefer ably constructed of sheet metal and secured in the block by having the latter molded, pressed, or otherwise constructed about the same.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which-1 Figure 1 is a perspective view of a build ing-block embodying the invention. Fig. 2 is a vertical sectional View thereof. Fig. 3 is a detail perspective view of the ventilator,

having the parts separated and arranged in a group.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The block 1 may be of any relative proportions and design, being formed with an opening 2 extending through opposite sides, so that when a number of such blocks are built into a wall the openings 2 thereof communicate and form, in effect, a continuous passage through which a circulation of air is maintained to carry off any dampness or odors. The block is provided in a side with a ventilator, the same consisting of sections having their outer ends flanged to overlap portions of a side of the block in which the ventilator is fitted. The sections comprising the ventilator are of such relative proportions as to admit of one snugly fitting within the other i and having a telescopic arrangement, whereby the ventilator may be adapted readily to the thickness of the side of the block in which it is located. The inner section consists of a thimble 3, having an outer flange 4 at one end, and is preferably formed of sheet material, such as galvanized iron, which is bent into cylindrical form, the meeting ends being secured in any substantial and practicable manner. The outer section of the ventilator consists of a thimble 5, having an outer flange 6 at one end, and is constructed in a like manner to the inner section.

A plate 7 is fitted to the flanged end of the thimble 5, preferably by having its edge portion bent so as to embrace the flange 6. A series of openings 8 are formed in the plate 7 and are preferably of sector form and spaced an equal distance apart. A damper 9 cooperates with the plate 7 to regulate the open ings 8. This damper consists of a disk or circular plate h aving openings 10 corresponding in number and position with the openings 8 of the plate 7, so as to register therewith in one position of the damper. In the preferable construction the damper 9 is arranged upon the inner side of the plate 7, so as to be housed and protected thereby. The ventilating-openings, consisting of the apertures 8 and 10, are protected in a manner to secludethe passage of mice, vermin, and the like without materially interfering with the free circulation of air. The protector 11 preferably consists of wirefabric, although foraminous or reticulated material of any kind may be employed. This protector is preferably applied to the damper and is located upon the inner side thereof, thereby admitting of the outer side of the damper having a close fit against the inner side of the plate 7. The damper is adapted to have a rotary movement imparted thereto and is connected to the plate 7 by means of a pivot 12 or other suitab e fastening. A knob or finger-piece 13 is attached to the damper and projects outward therefrom and serves as convenient means for manipulating the damper when it is required to open or close the same. This knob operates in one of the openings 8, and the latter has a notch 14 at one side to receive the inner end of the knob and admit of the damper being opened to the full capacity of the ventilating-openings.

This invention contemplates applying the ventilator to the building-block when constructing the latter, said ventilator being ar ranged in the mold or pressed in such a position as to admit of the material being stamped or otherwise shaped about the said ventilator To facilitate construction of the block, the knob or finger-piece is removed, and after the block has been removed from the mold or press, the knob or finger-piece is placed in position. The flanges 4 and 6 at the outer ends of the telescopic section comprising the ventilator, give a finished appearance to the ventilator, limit the inward movement of its section, and insure the formation of a tight joint between said sections and the side of the block in which the ventilator is arranged.

It is proposed to furnish one or more ventilating-blocks with a certain number of other hollow blocksand in the construction of a wall one or more ventilating-blocks is arranged in said wall, with the ventilators faclng lnto the lower portion of a room or apartment and one or more ventilating-blocks lo cated with the ventilators facing outward a t or near the upper portion of said room or apartment. A wall so constructed will admit of thorough ventilation of a room or apartment without producing appreciable draft and will at the same time admit of the current of air circulating through. the wall a t all times to carry off dampness and prevent the same and frost from striking through the wall in cold weather.

Having thus described the invention, what. is claimed as new is A ventilator of the character and. for the purpose specified, comprising two telescopic thimbles, both of which are provided at their outer edges with outstanding flanges. the circular plate having its edge recurved to embrace the flange at the outer end of one of said thimbles and thereby secured thereto, said plate having openings therein and a notch in the side wall of one of said openings, a damper-plate arranged on the inner side of the first-named plate and having openings to register with the openings thereof, and the two plates pivoted together at the centers the outer edge of the damper-plate working within the reeurved edge of the first-named plate, a handle attached to the (liIJ'I'1PO1'-])l:tl0 and extending outwardly througl. one of the openings in the inst-named plate and arranged to enter the notch therein when the damper-plate is fully closed, and wire fabric or like protecting means secured to the inner side of the damper-plate.

In testimony whereof we affix our signatures in presence of two witnesses.
