SPECIFICATION forming part of Letters Patent No. 742,130, dated october so, 1903.

, Original application filed .Tilly Z2, 1902, Serial To all whom t may concern: l

Be it known that I, HENRY E. PARSON, a citizen of the United States of America, and a resident of the city and State of New York, have invented certain new and useful Improvements in Combustion Regulators for Locomotive-Furnaces, of which the following is a specification. f

This application is a division of my application, tiled July 22, 1902, Serial No. 116,586.

This invention relates to an improvement in the structural formation of a locomotivefurnace.

In a pending application, filed July 22,1902, Serial No. 116,586, I have described and claimed means for'increasing the grade of combustion in the locomotive fire-box and the automatic regulation of such means.

In carrying out the details of my abovementioned invention it has been found Ynecessary to vary the structural formation of the furnace, and hence the present invention is directed to such changes arranged and constructed in the manner best adapted for the use intended.

The preferred form of construction is illustrated in the accompanying drawings, in which- Figure 1 'is a side elevation of a locomotive, parts broken away for better disclosure. Fig. 2 is a detail View of the mechanism for regulating the force of the exhaust.`

Referring to the drawings, 1 represents the the usual feeddoor 2. Y.

3 represents the grate, comprising a fixed section 4. and a lmovable section 5. The fixed section is provided with the usual water-tubes 6 and comprises in the grate proper a series of detachable sections 7, grooved along their edges, as at 8, to encompass the water-tubes, the grooves terminating in an upwardly-tapered opening 9. The movable grate-section 5, may be of any well-known grate construction. The grate herein described has been found to best serve the purposes desired and is shown herein for Vthat reason. However, as the grate structure forms the subject-matter of a separate pending application, Serial No. 135,311, and no claim thereto is made (No model.)

herein it is to be understood that I contemplate the use of any desired construction of grate, simply requiring a fixed section arranged to permit the passage of a forced draft and a movable or swinging section.

The movable or swinging grate-section 5 is hinged at 10 to the front wall of the fire-box contiguous the feed-door 2 and is suitably operated through the medium of a hand-lever y1l, having'an inwardly-extending arm 12, the

free end of which is connected to the gratesection 5 through adink 13.

An ash-pit 14. of closed type underlies the fire-box, as illustrated, and is archedat 15 to accommodate one of the main axles. The

arching ofthe pit-practically divides the same in the pit 14. `The desired means I provide through the use of an auxiliary ash-receptacle '21,which lies within the plane of pit14,b'ut only beneath the fixed grate-section 4.. The receptacle comprises a closed box-like 'structurehaving a bottom 22 inclined upwardly in a rear Ward direction. As the blower 20 is positioned to direct its blast against this bottom, the inclination of the latter serves to vspread the blast beneath the entire bed of fuel resting upon the fixed grate-section 4,thus evenly distributing the current, as is highly desirable. The injector is fixed in a housing 23, mounted ou the front wall of the receptacle 21, the airadmission opening of which (the housing) is` provided with the usual damper 24, suitably controlled .by rod v25, projecting within reach of the operator. The forced-draft blower is suit-ably controlled bymeans automatically operated by a predetermined pressure of the engine boiler, such pressure operating through lever and valve mechanism 26 to start or shut off the supply of steam to the injectors. As this construction forms the u Aloweropen ends of the bells 34.

subject-matter of the application rst referred to herein, it will not be further described, as for the purpose of the present invention any means of controlling the injectors may be used. I have found it desirable to control the force of the draft by manual means in order to draw the gases of combustion through the fire-tube with sufficient force to prevent back pressure in the fire-box and the escape of gases from the furnacedoor when it is opened. r

The means referred to above comprise an extension 27, secured to the top of the usual exhaust-pipe, to Whichextension is telescopically fitted a pipe 28. A rack 29, fixed to the latter pipe, is adapted to be engaged by a pinion 30, mounted on a shaft 31, which shaft extends beyond the boiler of the locomotive and is provided with a fixed arm 32, connected to a handle-rod 33, disposed in position to be conveniently operated; Bellshaped deiiectors 3l are mountedA below the lower end of the stack surrol'inding pipe 28 to direct the escaping exhaust-steam into the stack and to produce an induced draft through the fire-tubes. 34: is provided to direct the escaping products ot combustion from the boiler-tubes lo the screen 35, through which they pass to the As pipe 2S is raised or lowered through the medium of the rack and pinion it will be evident that the mouth of said pipe 28 will be raised out of or lowered into the bells and the induced draft will be greater or less. The effective power of such forced and induced drafts may The usual deector,

be thus controlled and the best results obtained.

The ashes accumulating from the fuel are drawn forward onto the swinging grate-section 5, whence through the operation of lever 1l they may be dumped into the compartment 16 of ash-pit 14, and when the latter is filled, or practically so, the ashes may be forced back into compartment 17, doors 1S or 19 permitting removal when desired.

The structure described is specially adapt` ed for use with my forced-draft apparatus described in application Serial No. 116,586, but is capable of variations and changes Without departing from the spirit of my invention, and I desire it to be understood that I consider all such as within the scope of my invention.

What I claim as new is- In a locomotive, the combination of a closed fire-box provided with au ash-pit, a grate, a smoke-box, a receptacle beneath the grate having an inclined bottom, said receptacle being out of communication with the ashpit, means for directing a blast against the inclined bottom near the lower end thereof, and in a direction opposite to the dow of the products of combustion from the iire-box, and means for creating a draft in the smoke-box, substantially as described.

Signed by me at New York city, New York, this 8th day of December, 1902.

HENRY E. PARSON.
