VENTILATING AND LIGHTING ARRANGEMENT FO R STEAMERS OR STEAMSHIPS.

SPECIFICATION forming part of Letters Patent No. 646,591, dated April 3, 1900.

Application filed October '7, 1899. Serial No. 732,936. (No model.)

T0 to whom it rncty concern.-

Be it known that L'ARENDT ANGSTROM, naval architect, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Ventilatingand Lighting Arrangement for Steamers or Steamships, of which the following is a specification.

My invention relates to improvements in the construction of passenger steamers and steamships; and the object of the invention is to devise an arrangement in state-rooms with the passage-ways and saloons whereby a greater amount of state-room space may be provided, a more perfect system of ventilation and lighting for such state-rooms, and improved and more airy and better-lighted saloons; and it consists, essentially, of providing one or more state-room decks with the central passage-ways and lateral passagewaysextending outwardly therefrom to the outside of the upper works, such passageways, as well as the central passage-way, being provided with ventilating-openings and lighting-windows arranged as hereinafter more particularly explained.

Figure 1 is a sectional plan view of the lower state-room deck of a steamship arranged with my improvements. Fig. 2 is a quartersection similar to Fig. 1. Fig. 3 is a quartersection of the upper stateroom deck. Fig. 4 is a sectional perspective view showing the arrangement of the passage-ways and the lighting and ventilating devices designed to.

be used with my particular construction of state-rooms and cabins. Fig. 5 is an alternative form of lighting and ventilating devices.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the bow cabin, and B the stern cabin on the lower state-room deck.

0 is a central narrow passage-way connecting the cabins A and B, and D are lateral passage-Ways extending out from the central passage-way O and provided withend doors or windows d.

E is the stern cabin of the upper stateroom deck, and F the central passage-way connecting it with the front cabin, (not shown,) and G are lateral passage-ways provided with end doors or windows g. The passage-Ways F are directlyabove the passage-ways C, and the passage-ways G above the passage-ways D.

V II is a skylight having a central ridge and.

the hinged lights h, which are designed to be held up in any suitable manner.

In Fig. 4, in which the above-mentioned skylights are shown, I shall refer to the passage-ways G and D as the lateral passageways; but it will of course be understood that the central passage-ways O and F may be similarly arranged in the manner I now describe. I are cold-air ducts leading into the center of the passage-way D. J are registers made in the outside walls of the state-rooms K. J are openings preferably inclined from the top of the state-rooms K and extending out into the passageway G, where they are covered by suitably-arranged slats j j,of glass or a preferred form of prism. There are'openings sulficient between the prisms to permit of the escape of air as well as to permit of the admission of light into the lower state-rooms K. j are registers in the upper state-rooms L, through which the air is admitted from the ducts 7' at the top of the sides of the passage-way D. The ducts 7' are preferably situated above the doors k of the state-rooms K. [are ventilating-lights,preferably perforated, so as to allow of the egress of air. Such lights Z extend along the top of the outer walls of each state-room, and they serve to throw the light down into the state-room from the skylights H, as well as to permit of the polluted air in the state-rooms passing out through them and the openings in the skylights. Z are the doors of the upper state-rooms.

It will be seen from the construction above described that the cold or warm air may be introduced through the duct I into the passage way D, and thence not only pass through such passage-way, but pass through the register J up through the ducts j and into the upper passage and through duct 7' into the upper state-room L, whence it passes through the upper lights Z and out through the skylights I-I, thereby providing perfect ventilation of the state-rooms. Not only is perfect ventilation provided, but the light from the skylight would pass through the ventilatinglights Z- into the upper state-room and would also be deflected through the slats j into the lower state-room K.

Instead of providing the lights as indicated for deflecting into the lower state-room I may provide lights j in the side and leave an opening) at the side of the upper passage-way, in which case I would provide a rail at the top of the opening. (See Fig. 5.)

My ventilating and lighting apparatus and general arrangement of state-rooms hereinbefore described, it will be seen, are particularly advantageous in large palace steamers or steamships, and I find in practice that I can procure about one-third more state-rooms and that the saloons will be lighter and more airy and better adapted for passenger traflic.

Although I describe the air as introduced at the bottom through the ducts I, it will of course be understood that the air may be introduced through registers in the doors at the ends of the lateral passage-ways.

\Vhat I claim as my invention is- 1. In a steamerorsteamship, the state-room deck, passage-ways extending Iherethrough, at right angles one above the other, and to the outer wall of the upper works, an air-register located at the bottom of each stateroom, an air-cond uctingandlight-transmitting duct at the top and a skylight for the top of the passage-way as and for the purpose specified.

2. In a steameror steamship, the state-room decks located one above the other, passageways extending t-herethrough, at right angles one above the other, and to the outer wall of the upper works, an air-register located at the bottom of each state-room and communicating with the passage-way, a duct leading from the top of the wall of the state-room above the register into the passage-way, a suitable light-transmitting and ventilating cover therefor and a skylight for the top of the passage-way as and for the purpose specified.

3. In a steamer orsteamship, the state-room decks located one above the other, passageways extending therethrough, at right angles one above the other, and to the outer Wall of the upper works, an air-register located at the bottom of each state-room and communicating with the passage-way, a duet leading from the top of the wall of the state-room above the register into thepassage-way, asuitable lighttransmitting and ventilating cover therefor, a skylight for the top of the passage-way and an air-duet leading into the lower passagewayas and for the purpose specified.
