UNIDEEFEED FURNACE.
Specification of Letters Patent.
Patented June 10, 1919.
Application filed February 21, 1919. Serial No. 278,349.
To all whom it may concern: I
Be it known that I, FRED A. SIEVERLING, a citizen of the United States, residing at Great Bend, in the county of Barton and State of Kansas, have invented certain new and useful Improvements in Underfeed Fun naces, of which the following is a specification. a
My invention relates to improvements in underfeed furnaces.
The object of my invention is to provide in an under feed furnace novel means by which fuel may be easily fed into the fire boX of the furnace in a cleanly sanitary manner, without wasting coal or scattering it about, without the opening of doors of the furnace and without permitting smoke, soot or ashes to escape into the room containing the furnace.
A further object of my invention is to provide a novel fuel feeding mechanism which can be readily applied to furnaces now in use with slight alterations of the latter.
The novel features of my invention are hereinafter fully described and claimed.
In the accompanying drawings, which illustrate the preferred embodiment of my invention, as applied to an ordinary hot air 7 furnace,
Figure 1 is a view partly in perspective and partly broken away and in vertical section of a furnace provided with my improvement, the plunger being shown withdrawn.
Fig. 2 is a central vertical sectional view of the lower portion of a furnace provided with my improvement, the plunger being shown in the chute.
Fig. 3 is a horizontal sectional view on the line 3--3 of Fig. 2.
Fig. 4 is a side elevation of the pinion and its support and parts connected therewith.
Similar reference characters designate similar parts in the different views.
1 and 2 designate respectively the inner and outer shells of an ordinary hot air furnace.
3 designates the grate rest mounted in the inner shell 1 and supporting a circular grate 4 having a central opening, preferably circular.
5 designates fire brick lining supported on the grate rest 3 and provided with transverse air holes 6.
7 designates an arcuate chute, preferably circular in cross section, andhaving open ends which face upwardly, the inner end extending through and being supported by the grate 4 upon which the chute discharges fuel 8. The outer end of the feed chute 7 is, preferably, located at the outer side of the outer shell 2 and provided with a flaring upper end adapted to receive the fuel.
For manually forcing the fuel 8 inwardly through the chute 7 there is provided a plunger provided with a head 9 adapted for oscillation in the feed chute 7 and for withdrawal therefrom to the position shown in Fig. 1. 'The head 9 is mounted on an arm 10 which extends into a housing 11 connecting the shells 1 and 2 and provided with a slot 12 which registers with a slot 13 in the outer casing shell 2. The arm 10 extends through the slots 12 and 13 and is pivoted by a horizontal pin 14 to two ears 15 of a plate 16, which is secured to the outer side of the inner shell 1. The housing 11 serves to preyent air from the room in which the furnace is located getting into the space between the shells land 2 and for preventing hot air from getting from said space into the room.
For oscillating the arm 10, it has} an arcuate toothed portion 17 which meshes with a pinion 18, which is secured to a horizontal shaft 19 rotatably mounted in two outwardly extending brackets 20, which are secured to a vertical plate 21 which is attached to the outerside of the outer shell 2 and forms the outside of the housing 11.
For manually turning the shaft 19 and with it the pinion 18, the shaft 19 may have attached to it a crank 22.
When fuel is to be fed into the chute 7, the crank 22 is turned so as to swing the arm 10 to the position shown in Fig. 1, in which position, the head 9 will be withdrawn from and will be above the upper outer end of the feed chute. The coal or other fuel 8 may then be fed into the outer flaring end of the feed chute. The crank 22 is then turned so as to swing the plunger head 9 into the chute, thus forcing the fuel inwardly through the chute and upwardly through the grate 4 upon which the fuel is discharged. The upper side of the head 9 may be sloping so that fuel will not rest upon it. When the head 9 is in the chute, it prevents an inward draft through the chute. If desired the arm 10 may be adjusted so that the head 9 will be at different distances above the open outer end of the feed chute 7, so as to variably regulate draft through the chute after the manner of a damper.
In the operation of feeding, with my de vice, it is not necessary to open any of the furnace doors, and the escape into the room of smoke, soot, dust or ashes is thus avoided.
The inlet end of the chute maybeat any desired height, and it maybe low enough to permit a child to readily deposit fuel into the chute.
I do not limit my invention to the structure shown and described, as modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.
'What I claim is 1. In an underfeed furnace, a casing comprising an inner shell 'and an outer shell spaced apart, a housing connecting said shells, a grate in said inner shell, an arcuate feed chute extending through said shells and having open ends facing upwardly, the inner end discharging through said grate and the outer end located outside of the outer shell, a plunger adapted foroscillation in said feed chute provided with an arm extending into said housing, and means in said housing for pivotally supporting said cillation in said'feed chute and for withdrawal therefrom provided With an arm havlng an arcuate toothed -port1on,- means for pivotallysupporting saidrarm in said housing, apinion meshing with said toothed portion, turning said pinion. 1
In testimony whereof I have signed my name to this specification.
