2 Claims.
The present invention relates to new and useful improvements in devices for eliminating dust from an ash can while depositing ashes from a furnace into the can and the invention has for its primary object to provide relatively simple and practical means for carrying out this purpose.
An important object of the invention is to provide a dust eliminating device of this character adapted for removably mounting on ash cans of vario-us sizes.
Still another object of the invention is to provide a suction device adapted for attaching on top of an ash can for removing dust from the ash can and returning the same to a furnace thereby preventing dust from entering a furnace room while ashes are being removed from a furnace.
Other objects and advantages reside in the details of construction and o-peration as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure 1 is a perspective View of the invention in place ready for' operation.
Figure 2 is a fragmentary sectional view taken on line l2--2 of Figure 1, and
Figure 3 is a perspective View of a diffuser at the discharge end of the device and with parts broken away and shown in section.
Referring now to the drawing in detail wherein for thepurpose of illustration I have disclosed a preferred embodiment of the invention the numeral 5 designates a flat semi-circular plate with a vertical flange 6 welded or otherwise joined thereto at the underside of the plate adjacent the edges thereof. Near the curved edge of the plate is drilled a hole or air vent 1 and controlling communication through the hole is a cover plate 8 pivoted to swing on a pin 9 at the underside of the plate, the cover having a downwardly extending inger grip I0 for moving the cover to adjust the size of the opening 1.
Located over the opening 1 and suitably secured on the top surface of the plate is a metal case I I with a small hole I2 in its top and a neck I3 integrally cast therewith, the neck projecting outwardly from the case at one side thereof and formed at its end with an out-turned flange I4.
An electric motor I5 is secured on top of the case I I with a vertical shaft IS extending through the hole I2 into the case. On the lower end of the shaft is secured a propeller having a plurality of blades I1 arranged upon rotation thereof to cause air to be drawn through the opening 1 into the case and forced out through the neck I3,y
thereof. On the side of the motor I5 is a switch I8 and electric wires I9 extend from the motor to a plug 20 for connecting the motor to an outlet of a house circuit.
A flexible metal tube or conduit 2l is secured at one end in the neck I3 and is. held in place on top of the plate 5 by a U-bracket 22 which is bolted or otherwise secured to the plate. The outer end of the tube 2| is secured a diffuser 23 including a neck 24 secured to the tube by a set screw 25.
A circular baffle 26 is iixedly secured in the diffuser transversely thereof Vand with the edges of the baille spaced from the sides of the diffuser, the baiiie being secured in -position by pins 21.
In the operation of the device the plate 5 is supported in position on top of an ash can 30 adjacent a furnace 3l, the stack damper, not shown, for the furnace being open. The diffuser 23 is positioned in the coal feeding opening of the furnace With'the furnace door '2B and ash pit door 29 also open.
The electric motor I5 is started and as ashes are shoveled into the ash can from the ash pit of the furnace the dust in the ash can is drawn up through the opening 1 by the blades I1 of the propeller and forced through the exible tube 2i and the diffuser 23 back into the furnace, the dust then passing out through the flue of the furnace. The escape of dust from the ash can into the furnace room is thus eliminated and after the ash can has been filled with ashes the plate 5 and suction attachment is removed from the ash can until it is again desired to be used.
In View of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.
It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the sco-pe of the appended claims.
I claim:
1. Means for exhausting dust from an ash receptacle to a furnace comprising a receptacle open at one end, a plate closing a portion of the open end of said receptacle, said plate provided with an air vent; a valve pivoted to said plate for controlling the flow of air through the air vent, an exhaust conduit communicating with the vent and adapted to extend into a furnace, a fan UNITED STATES PATENTS housed on said plate and including a propeller Number Name Date for directing the air from said receptacle to said 462 067 Schickler Oct 27 1891 conduit, and mants for diffusing a flow of air l 065953 May Jul'y 1 1913 leaving said con ui "T""'""""" 2.
