Patented Sept. 1, 1914 It. TANNBNBAUM. ASH REMOVER.
APPLIOATION FILED APR.14, 1913.
ROBERT TANNENBAUM, OF CINCINNATI, OHIO.
Specification of Letters Patent.
Application filed April 14, 1913. Serial No. 760,876.
To all whom it may concern Be it known that I, ROBERT TANNENBAUM,
a subject of the Emperor of Austria-Hungary, residing in Cincinnati, in the county of Hamilton and ,State of Ohio, have invented a certain new and useful Improvement in Ash-Removers, of which the following is a full, clear, and exact description, reference being had, to the accompanying drawings, forming a part of this specification.
My invention relates toa device for the removal of ashes from the ash-pit of a furnace; and has for its object the provision of such a .device of simple and inexpensive construction, which may be readily applied to anysort of furnace either in its original installation or thereafter; and which will effectively remove all ashes and cinders from the ash-pit without liberating any portion thereof into the cellar or other part of the house to cause undesirable dust and dirt.
In the drawings: Figure 1 is a sectional view showing my new ash remover as applied to an ordinary hot air furnace; Fig. 2
is a similar view showing its installation in connection with the furnace of a steam boiler; Fig. 3 is a cross-section of the device as attached to the furnace of Fig. 2.
The numeral 1 indicates the grate-bars of a furnace of any construction or type; below said grate-bars is the ash-pit 2; the ash-pit has walls 3, which converge to an opening 4:
and cause all falling ashes to fall through said opening. Below the ash-pit is a cylindrical pipe, or barrel, 5; said barrel being provided with an opening registering with the opening 4: in the ash-pit. The barrel 5 extends out through the side of the furnace and to any desirable point where the ash can 6 may be set to receive the discharged. ashes. Rotatably mounted in the barrel 5 is a large worm 7, the lower end of said worm occupying the lower end of the barrel immediately below the opening 4, so that the falling ashes come into contact with the worm. The diameter of the worm is approximately equal to the inside diameter of the barrel, there being enough difference, however, to allow for free rotation of the worm 1n the barrel. The upper end of the worm is provided with an operating crank 8, by means of which the worm is rotated. The barrel 5 is provided, on its outer end, with a depending spout 9, through which the ashes aredischarged intothe can 6, the spout'fittlng into a hole in the lid 10 of the can to prevent the liberation of light, impalpable particles of ash. Fitting around the spout 9 is a sliding collar 11 which also aids in preventingthe. liberation of dust and dirt. The side. edges 12 of the opening 4 in the ash-pit, are slightly above the axis of the Worm 7, and said edges are somewhat sharpened, as clearly shown in F ig. 3, so that cinders may not clog the worm during their entrance into'the barrel.
In Figs. 2-and 3 I have shown the worm 7 and barrel 5 as used in connection with the elongated firebox and ash-pit of a steam boiler furnace. In such connection, I employ a second, horizontal worm 13, which operates in a pit or channel 14 between the sloping walls 3 of the ash pit. 1 The edges of the pit are slightly above the axis of the worm l3 and are sharpened, as shown at 12, to prevent cinders from clogging the device, as above explained. The horizontal worm 13 is journaled at 15 and 16 at the two ends of the ash-pit. Secured to the end of the shaft of worm 7 by means of a universal joint 17, is a shaft 18, the free end of the shaft being journaled at 19 in the end wall of the ash-pit and being provided with a gear wheel 20 which intermeshes with a Patented Sept. 1, 1914.
gear wheel 21 on the endof the shaft of outside of the ash-pit preferably and are provided with a housing 22. One end of the worm 13 is over the inside end of worm 7, and the pit 14 slopes down, so that the ashes may be carried by worm 13 to worm 7 for removal from the pit. In actuating the worms 7 and 13, the crank 8 may be used, or, if desirable, as it would be where the ashes were to bemoved to a considerable distance, a crank'23 may be provided on the end of the shaft of worm 13. The worms 7 and 13 are provided with spirals in opposite directions, so that when running in 0pposite directions the ashes will be propelled in one direction. This is done to obviate the necessity for intermediate gear between the gears 20 and 21.
The operation of my invention will be obvious from the above description. By rotating the worm 7 or the worms 7 and 13 by means of the crank 8 or 23, the ashes will be moved, actuated by the spirals ofthe worms, from the ash-pit of the furnace to the place at which it is desired to'discharge them. This place is illustrated the drawings by the can 6 located near the furnace, but it is obvious that the place of discharge may be at a considerable distance from the furnace, as for instance, outside the building. Such variations in details as may be required for the purpose of carrying the ashes to a greater or less distance, as, for instance, in the arrangement and number of the worms and the means of actuating the same, are contemplated within the scope of my invention. Wherever the channel through which the ashes are to be moved is not straight, it will be understood that a plurality of Worms angularly disposed is necessary, on the principle illustrated inFig. 2 of the drawings, and such multiplication and arrangement are considered as within the disclosure of the drawings and specification herein.
Having thus described my invention,
What I claim as new and desire to secure by Letters Patent, is I The combination with the ash-pit 'of a furnace, said ash-pit being provided with walls converging downwardly into a channel in the bottom 'of said ash pit, of a worm adapted to rotate in said channel, said worm being journaled in the ends of said ash-pit and one end of the shaft of said worm from said channel are directed into said barrel and into contact with said second worm, a shaft operatively connected with the internal end of said second Worm, said shaft being journal'ed in the end of said ash-pit and projecting beyond the same, a gear on the outer end of said shaft, said gear belngadapted to intermesh with the gear on the shaft of the first worm, and a crank on the shaft of said first worm whereby both of said worms may be rotated to remove ashes from said ash-pit through said barrel.
