DUST-COLLECTING DEVICE.
SPECIFICATION forming part of Letters mat No. 534,120, datedFebruary 12, 1895. Application filed April 9,1894. Serla1No.506,869- (No model.)
To all whom it may concern Be it known that I, OLIVER 'R.'MOFFET, of Grand Falls, in the county of Newton and State of Missouri, have invented certain new and useful Improvements in Dust-Collecting Devices, of which the following is a full, clear, and exact description.
The object of the invention is to provide certain new and useful improvements in treatdrawings, forming a part of this specification,
in which similar letters of reference indicate corresponding parts in all the figures.
Figure l is a sectional plan view of theimprovement. Fig. 2 is a sectional side elevation of the same on the line 2- 2 of Fig. 1; and Fig. 3 is atransverse section of the same on the line 3-3 of Fig. 1. 1 In order to successfully treat waste fumes to retain the minute particles of valuable ma terial, I providea series of connected outlet channels A connected with the escape flue B of the furnace of any approved construction. The outermost end of the last channel in the series of connected channels A is connected by an opening 0 with a settling chamber D connected at its rear end by a passage E with the bottom of the chimney F. In this settling chamber D is arranged a strainer G provided with a frame G formed on opposite sides with. trunnions G journaled in suitable bearings in the side walls of the settling chamber D, so that the said frame can oscillate or be shaken for the purpose hereinafter more fully described. I
' The frame G is filled with hay,straw, wool or other material G and it corresponds to the cross section of the settling chamber D, so that all the fumes entering from the series of connected channels A into the said settling chamber must pass through the strainer before reaching the chimney F. The fumes in passing through the loose material G are deprived of their minute particles which are caught and collected in the said material, from which they can be shaken from time to time by oscillating the said strainer G. For this purpose a spring H presses on the lower rear end of the said strainer, while the front is engaged opposite the said spring by an arm I held 'on a transverselyextending shaft J, journaled in suitable bearings in the side walls of the settling chamber D.
One end of the shaft J extends to the outside and is provided with an arm J, connected with a rope K, adapted to be pulled so as to impart a swinging motion to the said shaft J, to move its arm I against the lower end of the pivoted strainer G, to swing the latter rearward at its lower end and compress the spring H, so that on the release of the rope K the spring H again forces the lower end of the strainer forward to return the latter to its normal position. By this arrangement an oscillating and shaking motion is given to the strainer, so that the valuable particles collected in the loose material G are caused to drop onto the bottom of the settling chamber, from which they can be removed fromtime to time through a suitable door D in the fron endof the said chamber.
It is understood that any desired number of such strainers may be set in the settling chamber if desired. The material deposited and collected in the settling chamber D is composed of sulphate, sulphide, carbonate and oxide of lead, in case ordinary galena ore is smelted, and when carbonate of lead ores are treated in the furnace, then the valuable material collectedconsists mainly of oxide and carbonate of lead. If the ores smelted are argentiferous ores of lead, then the valuable particles collected in the settling chamber will contain in addition to the above mentioned salts of lead, corresponding salts of silver.
The materials collected may either be used as a gray pigment direct, or after purification as a white pigment, or may be pressed into brick form and returned to the slag eye furnace and reworked for the metals which they contain. c
I am aware that devices for collecting the waste fumes of smelting furnaces in long fiues have been used.
Having thus fully described my invention,
I claim as new and desire to secure by Letters Patent- 1. In a dust collecting device for a metallurgical furnace, the combination with a settling chamber of a movable strainer, means for flexibly holding it to a definite or normal position,andindependentmeansforremoving it from such position to agitate it and dislodge the dust substantially as and for the purpose described.
2. In a dust collecting device for a metallurgical furnace, the combination of a settling chamber D having upon one side a winding flue or connected channels A, communicating with the escape flue of the furnace, doors D D, and a discharge flue or chimney F, a strainer pivoted or trunnioned within the settling chamber, a spring for holding the strainer to a definite normal position, and a rock shaft and shaker arm arranged to rock the strainer against the tension of the spring, substantially as and for the purpose described. 3. In a device of the class described, the combination with a settling chamber, of a strainer pivoted in the said chamber, aspring pressing on the said strainer, and a shaft having an arm adapted to engage the said strainer to swing the latter in one direction against the tension of the said spring, substantially as shown and described.
OLIVER R. MOFFET.
