HOOD AND SMOKE-PIPE FOR LOCOIVIOTIVE-ROUNDHOUSES.

Specification of Letters Patent.

ratented April 24, 1966.

Application filed May 8, 1905. Serial No. 259.4182.

To all whom it may con/:ern:

Be it known that I, EDWARD SPENCER PIPER, of the city of Toronto,in the Province of Ontario, Canada, have invented certain new and useful improvements in Hoods and Smoke-Pipes for Locomotive-Roundhouses, of which the following is a speciiication.

The object of my invention is to devise a convenient, simple, and durable hood and smoke pipe for locomotive roundhouses and it consists, essentially, of a box supported within the roundhouse and having its end provided with a door normally closing the end, but adapted to be moved by the smoke-pipes of a locomotive to permit the pipes to pass into or out of the hood, and of a smoke-pipe composed of a plurality of sections of some non-metallic fireproof substance connected by metal frames, substantially as hereinafter more specifically described and then definitely claimed.

Figurel is a side sectional elevation of my Fig. 2 is a improved hood and smoke-pipecross-section of the hood. Fig. 3 is a perspective view of the smoke-pipe,partly broken away. Fig. 4 is a sectional detail showing a modification of the framing of the smokeripe ln the drawings like letters of reference'indicate corresponding parts in the different figures.

Referring particularly to Figs. 1 and 2, A represents a portion of the roof of a locomotive-roundhouse. Under this roof is supported the hood B, formed as a box or trough, open at each end and at the under side. The ends are normally closed by doors O, each door comprising two sections horizontally hinged together at the center of the door and pivoted on the hood at or near the u per sides ofthe doors. The weight of these c oors normally maintains them closed, shown on the right hand in Fig. 1. The pressure of a locomotive smoke pipe will, however, open them, as shown on the left hand in the same figure, and as soon as the smokepipe has passed by the door will resume its normal position. The gates, it will be seen,will also yield readily to permit the smoke-pipe passing out of the hood. By my arrangement l avoid all necessity for swinging or lowering the hood, which is a great saving of labor and trouble, and at the same time avoids all possibility of the hood becoming injured or destroyed by a locomotive. The

top of the hood has an opening therein communicating with the interior of the smokepipe D, which will be hereinafter more particularly described. As it is desirable to be able to draw up the chimney the smoke and gases which may accumulate under the roof A above the level of the lower edge of the hood,

l provide the hood with a series of openings E near its top, at one or both sides. These openings are controlled by any suitable dampers. ln Fig. 2 l show hinged dampers F. Cords G, suitably weighted and passing round guide-pulleys, serve normally to keep the dampers closed. Other cords H, passing round suitable guide-pulleys and secured to the dampers, serve as means vfor opening the I dampers when required.

The smoke-stack comprises a framing I, composed of vertical grooved metal bars. These may be T-bars, as shown in Fig. 3, or double U-bars, as shown in Fig. a. These bars are secured to the base J in any suitable manner and also to the top K. Into the grooves of the bars are slid a series of sections or staves L, formed of some suitable noncorrosible iireproof material, preferably nonmetallic. These sections may be of wood, suitably fireproofed, of asbestos board, slate, tiles, wired glass,or other equivalent materials. Bands or hoops M surround the outside of the pipe and serve to maintain the parts in position. These bands are particularly necessary when the construction shown in Fig. 3 is employed. The sections L are preferably tapered, so as to produce a tapered pipe, as shown.

Tithin the chimney is located a suitable damper N, operated in any desired manner.

A chimney-pipe constructed as described willbe easily built, fireproof, and durable. The sides of the hood are preferably constructed in much the same manner as the chimney-pipethat is, by a metal frame O with panels P of non-corrosible tireproof material held therein.

Vhatl claim as my invention is- 1. In a device of the class described a hood open at its under side and provided at one end with a door normally tending to assume a closed position but adapted to be moved by the smoke-stack of a locomotive to )e1-mit the stack to pass into or out of the hood, substantially as described.

2. In a device of the class described a hood open at its under side and provided at one IOO IIO

top, substantially as describe 3. In a device of the class described a hood open at its under side and provided at one end with 'a door normally tending to assume a closed position, but adapted to be moved by the smoke-stack of a locomotive to permit the stack to pass into or out of the hood in combination With a smokeipe communicating With the top of the hoo substantially as described.

4. In a device of the class described a hood open at its under side and provided at one end With a door normally tending to assume a closed position but adapted to be moved by the smoke-stack of a locomotive to permit the stack to pass into or out of the hood, in combination with a smokei e communicating With the top of the hood Iboth the hood and smoke-pipe being formed of sections of noncorrosible iireprooi material connected by metal framing, substantially as described.

5. In a device of the class described, a hood open at its under side and rovided at one end With a door horizonta y hinged at or near its top on the hood whereby it tends to maintain a closed position, but is adapted to be moved by the smoke-stack of a locomotive to permit the stack to ass into or out of the hood, substantially as escribed.

6. Ina device of the class described, a hood open at its under side and provided at one end With a door formed in tWo parts horizontally hinged together, the upper part being pivoted on the hood so as to tend to assume a closed position but adapted to be moved by the smoke-stack of a locomotive to permit the stack to pass into and out of the hood, substantially as described.
