JOHN H. LORIMER, OF PHILADELPHIA, PENNSYLVANIA.

MEANS FOR VENTILATING DYE-HOUSES OR BLEAGHERIES.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed October 13, 1905. Serial No. 282,544.

To all whom it may concern:

Be it known that I, JoHN H. LORIMER, of the city and county of Philadelphia, State of Pennsylvania, have invented an Improvement in Means for Ventilating Dye- Houses or Bleacheries, of which the following is a specification.

My invention has reference to means for ventilating dye houses or bleacheries, and consists of certain improvements which are fully set forth in the following specification and shown in the accompanying drawings which form a part thereof.

Indye houses and bleacheries, as usually constructed, great difficulty has been experienced in properly ventilating them in cold weather when the rising vapors are condensed into a dense atmosphere of steam. Because of these conditions it is almost, if not quite impossible, to maintain'the efficiency of labor conditions or secure even a fair working condition. This condensation of steam or vapor renders the "atmosphere damp in cold weather, and the accumulations of damaging gases in bleacheries from the want of ventilation in cold weather, introduce conditions very detrimental to the workmen.

The object of my invention is to overcome these 0bjections by providing a system of ventilation which shall cause all vapors and gases to be carried away as soon as they rise, thereby maintaining the dye house or bleachcry in a habitable condition at all times and under all variations of temperature.

In carrying out my invention I provide the dye house or bleachery with a ceiling having one or more inclined surfaces communicating at their highest portions with chimneys extending sufliciently high to carry away the contaminated atmosphere.

My invention also comprises a hollow compartment above the ceiling through which air is caused to circulate and escape through apertures adjacent to the lowermost part of the inclined ceiling, whereby the air in rising along the under surface of the ceiling carries with it the ascending vapors and gases and conveys them to the ventilating chimneys.

My invention further includes means to force the air through the compartment above the ceiling to more positively insure the circulation when desired.

My invention also comprehends details of construction which, together with the features above specified, will be better understood by reference to the drawings, in which Figure 1 is a cross section on line 1--1 of Fig. 2 of the dye house or bleachery and shows my improvements applied thereto; and Fig. 2 is a longitudinal section thereof on line 2-2 of Fig. 1.

A is the dyeing or bleaching room and is provided with the inclined ceilings B, B, which communicate at their highest portions with the ventilating fiues C of which there may be any desired number. The lowermost portion of the ceilings may receive a supply of warm or relatively non-humid air by an opening D which preferably extends the length of the ceiling. Guards E may be arranged below the opening to deflect the air passing through the opening upward along the inclined ceilings B.

One or more floors G may be arranged in the building above the chamber F and above the ceilings B, and the said chamber may inclose trussed girders L which make the floor and ceiling substantial and self-sustaining.

The air passing into the chamber F for distribution to the ceilings may be admitted direct from the atmosphere outside of the building by controlled inlet I and pipe H, or it may be forced in by a blower .l and heated or otherwise prepared by passing through a chamber K as desired. In this manner the ascending vapors and steam from the vats meet warm and relatively dry layers of air adjacent to the ceilings and are carried along thereby and up the chimneys or ventilating fines C out of the building. It will thus be seen that the steam and vaporsare not permitted to remain in the room A, nor are they allowed to come in contact with a cold ceiling as heretofore. There is therefore no condensations within the room A and the atmosphere is comparatively free from vapors, steam and gases, such as are commonly found in dye houses and bleacheries during cold weather.

It is evident, that while I have shown a double ceiling inclined in opposite directions, the same results will be secured if only a single inclination is given to the ceiling, such as if the building comprised only one half of what is shown. 4

I do not confine myself to the details of construction shown as they may be modified without departing from the spirit of the invention.

Having now described my invention what I claim as new and desire to secure by Letters Patent, is

1. In a dye house or bleachery, a room having a ceiling bounding its highest part and covering its entire area made with its under-surface on a slight incline, combined with means for admitting fresh air directly to the lowest part of the ceiling, and escape lines from the room adjacent to the highest part of the under-surface of'the ceiling and extending upward to create a draft.

2. In a dye house or bleachcry, a room having a ceiling at its highest part constructed with an inclined under-surface and of the entire area of the room provided with apertures in the ceiling adjacent to its lowest portion to admit air from outside of the room to the lower part of the under-surface of the ceiling, escape flucs from the room adjacent to the upper or highest part of the ceiling, and means to force air through the aperture into the room adjacent to the lower portion of the ceiling, the air being directly delivered through the ceiling and caused to flow obliquely upward against the under-surface of the ceiling and pass to the outlet fines to carry with it the dense mass of Va pors within the room from the vats &c.

3. In a dye house or bleachery, a room having an oblique ceiling over its entire area and at its highest part, a chamber above the ceiling having a communication with the atmosphere exterior to the room and also having apertures opening into the room adjacent to the lowest portion of the ceiling, means for supplying air to the chamber above the ceiling, and escape ilues from the room adjacent to the highest portion of the ceiling and extending to the outside of the room for conveying air and moisture therefrom.

4. In a dye house or bieachery, a compartment having an -oblique ceiling over its entire area, a chamber above the ceiling having a communication with the atmosphere exteriox to the compartment and also having one or more apertures opening into the compartment adjacent to the lowest portion of the ceiling, escape flues from the compartment adjacent to the highest portion of the ceiling and extending to the outside of the compartment for con veying air and moisture out of the compartment, and means for heating the air or gas before passing into the chamber above the ceiling.

5. In a dye house or bleachery, a room unobstructed from its floor to its ceiling and said ceiling forming at the highest part of the room two inclined surfaces depending into the room and meeting at a place intermediate of the side walls and also having an area equal to the entire area of the room, combined with passages at the juncture of the two inclined surfaces for admitting air directly to the undersurfaces of the lowest whereby it may at once divide and pass over the oblique surfaces thereof in opposite directions, and escape flues opening from the room adjacent to the highest portions of the ceiling.

G. In a dye house or bleacher a room having at each side flues for the escape of moisture and air from the room and unobstructed between its floor and ceiling, combined with a continuous ceiling formed of the entire area of the walls, passages for admitting air directly through the lowest portions of the ceiling into the room whereby it may at once divide and rise over the oblique surfaces thereoi in opposite directions and escape through the fines and carry with it the moisture and objectionable gases which rise in the room, a iioor above the ceiling, and truss work between the said floor and the ceiling for suspending the ceiling and constituting a chamber between it and the floor to supply air to the passages extending through the lowest part of the celling and to prevent excessive chilling of the ceiling.

7. In a dye house or bleachery, a compartment having an oblique ceiling over its entire area, one or more apertures opening into the compartment adjacent to the lowest portion of the ceiling for supplying air to the compartment, escape fiues from the compartment adjacent to the highest portion of the ceiling and extending to the outside of the compartment for conveying air and moisture out of the compartment, and means for heating the air or gas before passing into the chamber above the ceiling.

8. In a dye house or blcachery, a room unobstructed from its floor to its ceiling and said ceiling forming at the highest part of the room two inclined surfaces depending into the room and meeting at a place intermediate of the side walls and also having an area equal to the entire area of the room, combined with passages at the juncture of the two inclined surfaces for admitting" air directly to the under-surfaces of the lowest portions of the ceiling whereby it may at once divide and pass over the oblique surfaces thereof in opposite directions, a shield E below the juncture of the two inclined surfaces of the ceiling for direct iug the air in opposite directions, and escape fines opening from the room adjacent to the highest portions of the ceiling.

In testimony hand.

of which invention, I hereunto set my JOHN II. LORIMER. Witnesses M. J. Evan,
