AUTOMATIC SMOKE-CONSUMER.

SPECIFICATION forming part of Letters Patent No. 438,005, dated October '7, 1890.

Application filed January 24,1890. Serial no. 338,033. (No model.)

To all whom it may concern.-

Be it known that I, GOTTHOLD LANGER, a citizen of the United States, residing at Trenton, in the county of Grundy and State of Missouri, have invented certain new and useful improvements in admitting air above the fire to furnaces and fire-boxes of steam-boilers for the purpose of preventing the accumulation of dense black smoke, of which the following is a specification.

Heretofore smoke has been prevented by admitting a certain per cent. of air above the fire through pipes or tubes set in and made solid in the sides of fire-boxes and furnaces; but said pipes and tubes standing open permanently result in a great loss of heat or evaporating power of the boiler and thereby increasing the expense of fuel for heating such furnaces or lire-boxes.

My invention is to prevent the accumulation and escape of dense black smoke by admitting air through pipes and tubes above the fire to furnaces and fire-boxes of steamboilers and to shut off the air automatically without the attention of engineer or fireman after it has accomplished its purpose, (of preventing the accumulation and escape of dense black smoke,) so as not to cool unnecessarily the interior of such furnaces and fire-boxes as to result in a loss of heat or evaporatingpower of the boiler. I attain these objects by the mechanism illustrated in the accompanying drawing, in which the figure is an end elevation of a steam-boiler and furnace provided with my improvement.

In the construction shown the globe-valve a admits and shuts off the steam when neces sary. After there is sufiicient steam-pressure in the boiler to admit the working of my invention the globe-valve a is left open. The rod b, which passes through the hinges of the firedoor and is made fast thereto by means of pins, is extended and used as a valve-stem,having a steam-tight valve attached to its lower end within the valvecasing 0. By opening the fire-door the rod b will have to turn in its bearings, and in so doing will turn the valve within the valve-casin g c. This movement will allow the steam to rush into the steamcylinder d and push the piston made fast to the piston-rod 7?, in the direction of the shaft m. (Represented at the left side of the draw ing.

The cylinder cl has a hole in one end (the left end in the drawing) just large enough to permit the easy movement of the piston-rod n and to hold the piston-rod n firmly in the center of the cylinder cl. The other end of the cylinder d (the end nearest the right side of the drawing) is made steam -tight with packing in the stuffing-box e.

The piston-rod 02 also passes through the stuffing-box e, and is made longenough to admit the compression of the spiral spring f to give it sufficient power of extension to force the piston-rod it back to the point of start ing. The piston-rod 'n has threads cut on it for a distance to allow the nut g to be screwed against the spiral spring f to adjust it accord ing to the time the air tubes or pipes are required to be left open. The piston-rod n, is fastened at both ends to connecting-rods, as o, and levers forged or cast on the shaft m.

The top of the shaft '01- has levers also, which are fastened to connecting-rods, similar 7 5 to 0, which are connected with a slide h, which is held by the gibs 7t and k to the bottom plate 7 which can be seen through the holes in the sliding plate h. This bottom plate 11 is fastened directly to the sides of the furnace or firebox. The bottom plate 1' and also the slide h have holes drilled through them at equal distances from center to center, so that when the slide h moves on the bottom plated it will either open or close the holes in the bottom plate 21 The tubes or pipes leading into the inside of the furnace or fire-box are the same distances from each other from center to center as the holes in the bottom plates and slides, so that when the plates 71 are fast- 0 ened over the tubes or pipes the openings in the tubes or pipes shall correspond to the holes in the plates and slides.

As the slide h is connected by connectingrods, like 0, to the shaft m, and the shaft on is 5 connected by its levers and connecting-rods with the piston-rod n, it follows that the movement of the slides, like h, is dependent upon the motion of the piston-rod n. Further, as the opening of the fire-d0or causes Ioo the steam to rush into the steam-cylinder d and move the piston-rod n, this movement will also cause the slides, like h, to move and open all the tubes covered by the slides and allow the air to pass into the fire-box.

The closing of the fire-door shuts off the steam, except the quantity of steam already in the cylinder cl. This steam in the cylinder 01 V will gradually condense, and thereby weaken the resistance which causes the compression of the spiral spring f. The spiral spring f will gradually overcome the resistance of the condensing steam, and by its power of' extension will push the piston-rod n and all its connections and slide back to their former positions as before opening the fire-door.

Other slides, which can be seen in the drawings, are connected to the sides of the boiler. The number of these slides depends upon the number of air-tubes to be inserted in the boiler.

The length of time for the tubes to be left open can be regulated by the nut g, which will increase or lessen the resistance of the spiral spring'f, and thereby shorten 0r lengthen the stroke of the piston-rod nand all slides connected thereto and controlled thereby;

In the bottom of the steam-cylinder d isa valve 00 on one end of the steam-cylinder d, and under the other end of the steam-cylinder cl is a drain-pipe to drain off the Water confined in the steam cylinder (Z and created by the? condensinggof the steam.
