AUTOMATIC HUTCH DEVICE FOR JIGS AND THE LIKE.

Application filed April 22, 1915, Serial No. 23,048.

To all whom it may concern Be it known that we, ALBERT J. SAYEns and JOHN H. D. PETERSEN, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Automatic Hutch Devices for Jigs and the like, of which the following is a specification.

Our invention relates to an automatic hutch for jigs.

It relates particularly to means for automatically and, periodically freeing the jig chamber from the accumulated fines.

It is illustrated in the accompanying drawings somewhat diagrammatically and with modifications.

Figure 1 is a cross section of a jig to which our invention has been applied; Fig. 2 is a section on the line 2-2 of Fig. 1; Fig. 3 is a section on the line 33 of Fig. 2; Fig. 4 is a section on the line 4.-l of Fig. 1; Fig. 5 is a section on the line 55 of Fig. l; Fig. 6 is a section on the line 6-6 of Fig. 4. with valve removed. Fig. 7 is a section through a modified form.

Like parts are indicated by the same let-- ter in all the figures.

A, A is a housing or tank divided up into three chambers A B, B. These chambers have inclined bottoms A located in the B, B are-plunger chambers in which move the plungers B B suspended from vertical rods B B which depend from the reciprocating eccentrically mounted heads B B on the shafts 13*, B which are mounted on the standards B B supporting the casing and its interior walls B B which form the plunger chambers. From each of the heads 13 projects a lug C to which is pivotally attached the link C the other end of which is pivotally attached to one end of the arm C the other end of which is pivoted on the shaft C Said arm carries a pawl 0 adapted to engage the teeth of the ratchet wheel C also mounted on the shaft C and integral with or attached to the beveled gear C. D is another beveled gear at right angles to the beveled gear C in mesh with it and mounted upon the vertical shaft D All these parts are suitably mounted and held in operative position upon a frame consisting of the bed plate D the standards D D and the bearings D D Each shaft D passes down- Specification of Letters Patent.

wardly and to its lower end is fastened a valve which consists of the separated side straps E, E and the bottom E containing the radially disposed apertures E This valve is received within the non-rotatable part E and rests upon a valve seat E being properly centered therein by the downwardly projecting part E on the valve which seats 1n a corresponding recess in the valve seat. The valve seat is provided with open- 1ngs E somewhat similar in shape to the openings E E in the valve. Obviously as the valve rotates it will cause the two sets of openlngs to register and thus provide an outlet from the lower part of the jig tank and the valve will be caused to rotate by the movement of the eccentrically mounted head B In order that the effective area of the outlet may be adjustable we provide an adusting ring F beneath the valve seat. It is provided with the openings F F and a square lug F whereby it may be rotated on its axis. The valve seat and ring are all contained within a centering plug G properly positioned and fixed in the bottom of the casing and beneath the tank.

It will be understood that the parts are so shaped that the fines will be brought as lndicated at J, J into a proper position above the valve in the bottom part of the tank.

In the modified form of the valve we provide at the bottom of the tank a valve seat K into which fits a plug valve K on a stem K and this stem is attached at K to a lever K pivoted at K and adapted at its other end to be engaged by some moving part'which will intermittently raise the valve. The valve rod or stem D or K may be housed in a tubular housing D or in the partition B, or if the partition is not required and a housing is, it may take the form illustrated in Fig. 7.

It will be understood that we do not wish to be limited to the particular size, proportion and arrangement of the several parts here illustrated and that my drawings are to be taken as in an important sense diagram matic, as great changes could be made in these particulars departing from the spirit of our invention.

The use and operation of our invention are as follows: The jigging operation in the particular form of jig'here illustrated conscreens.

from time to time utilized.

sists in forcing the water through the plunger chambers up through the jigging screens and the separation is effected and the material delivered in any desired manner according to the type of jig from above such A certain amount of so-called fines consisting either of the material to be saved, or refuse, or both, escapes through the screen and descends into the jig tank. This material must, of course, be carried away and various devices for that purpose have been An operator may open avalve or discharge opening from time to time or a steady stream of Water may be permitted to flow or such fines may be discharged into-a side projection of the main tank and be thence removed by conveyors. It is desirable that there should be the least possible waste of Water and frequent discharges. of the fines. According to the method utilized in our invention the fines are intermittently discharged with comparative frequency in relatively small masses with a minimum of water by the weight of the Water-above. Toput it in another way, we

. deliver a series of charges of fines intermittently. Any desired means for thus operating the valves intermittently may be employed, but we "have shown one, and, of course, that or any'like means is applicable to any kind of jig. The parts should be constructed orxset so as to properly time the action, and in like manner it is desirable to properly regulate the outlet. These adjust-- ments Will'be determined by the nature and quantity of'the material dealt with. The rotation of the driving shaft will properly reciprocate the plungers so as to effect the desired separation. The rotation of the same shaft will rotate the valves step by step, leaving: the discharge open for a relatively short space of time during each revolution-of the valve. The frequency of the valve rotation may, of course be adjusted by varying the point of connection between the rod C and'arm C andthe area of the outlets may be varied by rotating the adjusting plate by means of a wrench or handle. By effecting either or both of these adjustments from time to time the requirements of any given case may be met and there will be a series of relatively quick discharges of the accumulated material, the same passing out in a sort of charge by the action of the weight of the water above it.

e claim:
