Description

aen een aient 'Letters Patent No. 99,72
dated February 8, 1870.
IMPRQVED DEVIC FOR 'VENTILATING- AND COOLING- OR WARMING BEDS.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern Be it known that I, DANIEL E. Scams, of Washington, in the county of Washington, and in the District ot' Columbia, have invented a new and useful Improved Mode ot' Ventilating and Cooling or lVarming Beds; and I do hereby declare that the following is a full,` clear, and exact description thereof, reference being had to the annexed drawings, making part of this specification, in which- Figure -1 is an elevation of a bedstead, with my apparatus for supplying cold or warm air to thc same, the air-ducts for that purpose being shown partly in section, the left-hand side representing an air-duct carried underground tbrsoI-nedistance, while the righthand halt'oi' the figure shows a different arrangement ot' such duct.
Figure 2 is a plan view of the same.
Figure 3 shows, in the right-hand halt, two airiuets, extending above `the root' of a building, andsur- 'ounded at their bases by square boxes, and connected by pipes to the mattress of a bed, one at the head ot' the bed for forcing air into the same, and the other at the foot for drawing ofi' foul air. In the left-hand half, the duct for drawingofl' foul air is represented as directed into the chimney.
Figure 4 is a plan view of the parts shown in fig. 3.
Figure 5 is a plan view of a series ot' bedsteads, showing an air-duct, or ventilating-tuhe, with branchpipes for supplying air to thern. I
Figure 6 is a pla-n view of a series of bedsteads, or beds, showing two air-ducts,l one for directing a current ot' air into the bed, and the other for drawing oli air therefrom.
The same letters are used in all'the igures to designate like parts.
My invention relates to a mode of Ventilating, or cooling beds, and it consists in supplying air, properly tempered, to such beds, hy means ot' air-ducts carried above the roofs ot' buildings, and also in so arranging a second air-'duct iii-such a manner as to draw oiiV the foul air trom the hed or beds, all as will bemore fully set forth hereinafter.
To enable those skilled in the art to make and use my invention, I will proceed to describe its construotion and operation.
In the annexed drawings- A represents a bed, and v B, the air-duct for supplying either Warm or cold air to such bed.
1n the let't-hand half of figs. 1 and 2, I have represented the air-duct as carried underground for some distance, for the purpose ofimparting to the air circulating through it, the temperature of the earth, which, as iswell known, is nearly uniform throughout all seasons` of the year.
In the right-hand half of the same igures, this underground portion of the duct is dispensed with.
Either one of these arrangements may be used, as may be found most convenient or desirable.
"lhe air-duct extends above the root` C of the building for some considerable distance, and' has on top a cap or hood, with the necessary vane for turning the month ot' the hood toward the wind, which will thus be caught and circulate through the duct.
l To increase the downward current, as well as to cool the air descending, i propose to create, in warm weather, e 'a1-poration around a Vportion ofthe duct, and to this end, wind or aiix around it, above the roof', some fibrous material, as shown at Bl; upon which water is made to trickle down from a reservoir; B2, above it, said reservoir being supplied with water from a hydrant, or by'ineans ot' a pump. By such constantevaporation, heat is abstracted from the air as it descends the duct, and, consequently, the temperature in the duct considerably reduced. l
The duct encloses a cylinder, B, occupying its centre, so that the air descending itisconstantly brought in contact with its cold outer wall.
A portion ot' the duct may be enclosed in a suitable box, B, and in this box ice' or other cooling substances may be placed in summer time, when it is desirableV to have cool air for the bed or beds, and hot water or steam may be introduced into the saine during the cold season.
One branch-pipe, B5, provided with a suitable valve or damper, leads from the duct to each bed, discharging the air either directly over the bed, as shown in the left-hand section of figs. l and 2, or into a box placed above snch bed, and provided with a iine gauze bottom, for the purpose o't' dividing the current, as shown atl), in the left-haud section of sail iignres.
It is apparent that one `duct may be employed to supply any number ot beds with air ot' any desired temperature.. Y
lbe air-duct- B, iu figs. 3 and 4, discharges the air through its branchfpipe B5, directly into the mattress at the head ot' the bed, for the purpose ot Ventilating the same.. -A
Another duct, E, is here'einployed, for the purpose .of drawing olf from the bed any foul air therein, its
branch-pipe connecting with the mattress at the foot ot' the bed.
In the right-hand section of these figs-3 and 4, I
have shown this air-duct E as directed into the chimney F. When it is not convenient to emplo achimney for thus producing a draught, I employ a ventilating-tube or shaft, with one or more gas-jets directed into the saine at any convenient point.
In the righthand section l have shown an air-duct for drawing oii" foul air, like the duct B, with this difference, however, that the. vane is so attached to its revolving hood or cap as to point its month in the direction of the wind; thus a constant tendency to a 'vacuum at the mouth of the hood will create an upt conducted upward to fall upon it; or the air which is .g-onducted directly into the bed may be drawn outiut\o.this,sp: lce, and then toany desirable place.
In order to prevent the conduction of heat or cold through the lwalls of the boxes vor air-ducts, I surround them, below the eva-porating apparatus, with a casing or cisings, having spaces between them. These spaces are Atilled with some good non-conducting material or substance, as tow, wool, cotton, flax, hair, cork, felt, 'charco-al,y air, sawdust, tan-bark, shavings, plastei"ofPai'is, soapstone, soapstone-dnst, pipe-clay, or tire-brick. When itis desirable to purify, moisten, dry, perfume, or medicate the air, prior to its being inhaled by the occupant of the bed, I place in the airducts or cooling-boxes, charcoal, chloride of lime,
quick or air-slaked lime, carholic acid, ammonia; v also sponge, felt, or other fibrous substance filled with water, or water in the form of spray or jets. When water ls used inthe form of spray or jets, the airdncts are connected with a grand trunk, or main duct, down which the water is allowed to fall to be conducted away to any desirable point through a trap.
ln connecting the lateral branches to the main duet, care should be taken to prevent their receiving any of the falling water. This object may be secured by sloping downward that end of the lateral branch whit-his joined to the main due-t, or the end may be projected into the main duct withan opening inits-lower side only which will admit the air and exclude the water.
The mouths of the ducts are covered with wire, or other gauze, or its equivalent, to prevent the entrance of dust and insects.
I use vthe foregoing substances and materials in patents already granted to me for cooling and ventilating buildings, and I now propose to use them in combination with beds, in the manner as herein described.

1. A bed-sack, or mattress, in combinationwith. an air-duct extending to the outside of 'the building in which said bed is placed, substantially-as and for the purpose set forth.
