FRITZ HENRY GORDON, 0F IE'ORTLAND, OREGON.
DRY SEPARATOB AND CONCENTRATOR.
. Application filed April 6, 1914. Serial No. 829,760.
To all whom it may concern:
Be it known that I, FRITZ HENRY GORDON, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Dry Separators and Concentrators, of which the following is a specification.
My invention relates to an improvement in dry separators and concentrators, and
particularly to separators in which. minerals are separated from thin sheets of gravel, sand or the like, by means of currents of air under ressure.
A further object is to provide novel means for controlling the elements constituting the separator.
I accomplish the objects indicated by means of the structure shown in the accompanying drawing, in which- Figure 1 is a planview' of the, complete device. Fig. 2 is a longitudinal sectional view taken on the line AA of Fig. 1. Fig.
3 is a rear end elevation showing portions in section. Fig. 4 is a side elevation of a portion of the body of the separator.
Describing the drawing in detail, 1 designates the side members of a shaker formed preferably of metal, each having a longitudinal groove 6 in its lower edge to receive the tongue 7 on the upper edge of the corresponding side member 8 of the body portion of the device. Between the side members 1 intermediate their edges, is fixed the inclined floor 39 extending from the front to the rear end of the body portion of the machine,- and consisting of a series of transverse steps, over'which the metal tends to separate as it falls. 1
At suitable intervals along the angle irons 4 is arranged a series of riflie bars 34, between which air under pressure is forced 1 against the sheet of mineral matter passing over them. Intermediate each series of bars is placed a plate 39 each having an ofi-set or step in its upper face and each lying against the rifiie at each side, so that the heavy particles can escape only between the riflles. At the rear of the last series of bars is fixed a plane section 2 of the shaker floor which extends to the rear of the side members 1 and from its rear edge is a lateral projection 2, at each end of the section 2, upon which is pivotally connected an adjusting bolt 9 engaged in the eye bolts 5 which are secured in the sides of the shaker Specification of Letters Patent.
Patented Jan. 5., 1915.
and by means of which the floor sections are adjusted in the angle irons 4. The lock nuts 32 serve to adjust and secure the members in place.
Ilengthwise against the inner face of each side member' 1 is a plate 3 whose lower edge is made to conform to the irregularities of the upper faces of the floor sect1ons and upon the inner side of each side member 1 is a series of laterally projecting pins 3, each of which extends through a slot 41 formed in the plate 3, and which rises slightly to the rear. This arrangement allows the members 3 to be drawn to rear to free themfloor sections, so that they may be removed at will; and when the plates are forced forwardly the inclination of the slots causes them to bind firmly upon said secing through the rifiles. To the rear of each receptacle is formed an air chamber 50, which opens into and is continuous with the main body portion having front and-rear walls 49 and the bottom 51, which receives air from the blower 28. At the upper portion of each air chamber is secured a-' valve 12 upon the pivot 17. The arm 19 connected with the valve 12 is adapted to engage the segment rack 18 for controlling the chamber outlet.
In the upper end of each receptacle at an intermediate position is fixed a vertical spring plate 48 extending the full length of the receptacle; and from the upper edge of the rear wall of each receptacle is fixed a plate 15 which inclines downwardly and forwardly to a point below that of plate 48. Slightly to the front of the lower edge of each of the spring plates 48, upon the pivot rod 16, is mounted a valve 20 having an arm 14. adapted to engage in the segment rack 13,
whereby the valve may be operated to close against the edge of the spring plate, which will yield sufficiently to allow the said valve 20 to move against the inclined plate 15 thereby closing the passage into the receptacle which serves to retain the material during periods when the drawers 10 are removed, after which it will again be opened "pul ley 45 to operate the blower 28 which 1 communicates directly with the body portion of the machine, and which is controlled by a valve31. Upon shaft 27 is fix'ed another pulley 24 which carries a belt 25 to actuate the pulley 26 fixed upon the shaft 44. Upon the last mentioned shaft is fixed an eccentric 43 from which the connecting rod 46 leads to and connects with the shaker frame by means'of'the pivot pin 47, whereby, upon the application of power to the i shaft 27 air will be forced into the body portion and the shaker will be vibrated at the same time. Above the forward portion of the machine is supported a hopper 36 Inpon brackets 37 carried by the main frame 42. The outlet of the hopper is controlled by a slide-plate 38.-'
From the front edge of each series of rifle bars a partition wall 40 depends to the lower edge ofthe side members 1,. and it has a rearward irregularly curved surface which deflects the material passing through the rifles onto, the inclined plate 15. As the shaker frame is agitated the material will separate into a thin sheet over the sectional floor and gravitate over its inclined surface to the rear, the lighter particles passing over the rifles and accumulating at the end in the boxes 35. The valve 12 being hinged to the rear wall ofthe chamber 50 assumes a forwardinclination as it moves toward closed position, thereby giving a forward direction to the current of air issuing therefrom so as to direct it through the rifle bars 34. The current will be so controlled that its force will sustain the lighter particles andcause them to pass to the rear, while the heavier particles willdescend against the current into the receptacle below. A short distance above each set of rifles is secured a hood 33, whose functionis to break the force of the current rising and prevent the lighter particles from being carried above the shaker frame. 7 These hoods are adapted.
to swing on their pivotal supports 33* so as to give them the desired angle with refer- .ence to the direction of the current. Having described my invention, what I :claim,-isv a 1. The combination with a separator com- 6o prising a frame, a shaker having a plurality of screen openings mounted to vibrate therein, a body portion adapted to receive air under pressure fixed beneath the screen openings, a receptacle in the body portion beneath each screen, and an air chamber at the rear of each receptacle leading from the body portion to the screened opening, ofa forwardly inclined deflector in the shaker at the rear of each chamber and a forwardly closing valve at the outlet of each chamber. 2. A separator comprising a frame, a shaker having a plurality of screen openings mounted to vibrate therein, a body portion adapted to receive air under pressure fixed beneath the screen openings,a receptacle in the body portion beneath each screen, an air chamber at the rear of each receptable leading from the body portion to the screened opening, a forwardly inclined deflector in the shaker at the rear of each chamber, a forwardly closing valve at the outlet of each chamber and an adjustable hood mounted close to j and above each screen.
3. The combination with a separator or shaker comprising side members, each having an angle iron support lengthwise thereon, a plurality of rifles each comprising a series of bars secured transversely on said angle-irons, and floor sections each having an upper surface forming steps and overlapping the succeeding section to the rear said sections alternating with said rifles, of fastening means permitting longitudinal adjustment ofthe rifles and floor sections.
4. In a separator or shaker comprising side members, each having an angle iron support lengthwise thereon, a plurality of rifles each comprising a series of bars secured transversely on said angle-irons, floor sections each having an upper surface forming steps and overlapping the succeeding section to the rear, said sections alternating with said rifles, and plates having diagonal slots adapted to engage pins in each side member so as to be vertically adjustable for binding the sections and rifles.
5. In a separator of the character dc scribed, the combination with a shaker having a plurality of screened openings of a receptacle beneath each opening having a forwardly and downwardly inclined bafle plate adjacent its upper rearward edge a resiliently mounted depending plate disposed within the receptacle opposite the bafle plate and a hinged bafle plate extending at an incline from the lower edge of the depending plate to the lower edge of the first mentioned bafle plate.
In testimony whereof I aflx my signature in the presence of two witnesses.
