GEORGE'LAUDER, OF PITTSBURG, PENNSYLVANIA.
COAL AND ORE JIGGER.
[SPECIFICATION forming part of Letters Patent No. 364,265, dated June 7,1887. Application tiled September 23, 1886. Serial No. 214,322. (No model.)
To to whom it may concern:
Be it known that I, GEORGE LAUDER, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Coal and Ore Jiggers; and I do hereby declare the following to be a full, clear, and exact description thereof.
My invention relates particularly to effecting a better and more complete separation of the lighter from the heavier materials in the use of that class of machines used in coal and ore washing known as jiggers. It also increases the rapidity of the operation, and thereby effects a saving of time.
It consists, mainly, in the construction and arrangement of the'discharging devices. Usually these devices have been arranged one over the other at the end of the machine, at
suitable heights for the discharge of thelighter and heavier materials, and the whole body of the material. required to be lifted by the motion of the piston clear to the discharge end.
In my improved machine the lighter materials are taken off and discharged by means of a lateral discharge trough or box arranged over the screen'at a point in advance of the discharge end, and a clear space is left between said trough and the discharge end, so that the pulsations of the water caused by the piston shall be free to work on the layer of heavy material and cause it to be worked freely toward its dischargeopening, whereby clogging is prevented and a freeand rapid discharge is effected.-
in which-- Figure 1 is a longitudinal section of the ma chine on the line a: a; of Fig. 2. Fig.2 is a cross-section on the line 1 y of Fig. 1.
Like letters of reference indicate like parts in each figure.
Thejigger a; has the usual hopper-shaped body, with a cross-partition, a, dividing the upper part, on one side of which is the usual piston, b, and on the other side the usual screen, (1. \Vater is admitted to the jigger by means of a supply-pipe, c, at the piston end of the machine, and it flows through the ma chine and escapes at the discharge-openin g for the lighter materials, hereinafter described. At the discharge end of the machine is the usual receptacle, 7, in which is an elevator, for raising the material out of the receptacle. The water is maintained in the jigger a and receptacle f at a level indicated by the dotted lines .2, being the level of the dischargeopening for the lighter materials. Thejigger a communicates with the reeeptaelef by an opening, 0, at the discharge end of the ma ehine,which opening is designed to permit the discharge of the heavier materials. This opening is controlled by slides, gates, or doorsi k, the door z rising and being operated by means of the stem 2', and the door is falling and being operated by the stem is. The purpose of these doors is to regulate the size of the opening 0,
and also its altitude with relation to the dis charge-trough, so as to enable the operation of the machine to be better regulated.
Extending laterally entirely across the machine, over the screen (I and above the level of the dischargeopening e, is a trough or spout, h, preferably made, as indicated in Fig. 2, with its bottom inclined both ways from the middle. This discharge-spout is detached from the discharge end of the machine, so that there is a clear space over the screen (I between the discharge end and the spent 71, the purpose of which will be explained. The bottom of the machine is closed by a suitable door, at, the purpose of which is to give access thereto, so that it may be cleaned out and repairs facilitated.
As shown, the rear side of dischargetrongh spout h is hi her than the front side, being above the water 'level, to prevent the danger of lighter materials being washed clear over the trough. I
Thus constructed, the operation of my machine is as follows: The material is placed upon the screen d, between the dischargespout h and the partitiona, and, being subjected to the operation of the piston, itis spread in layers by the pulsations of the water, as will be understood, the lighter portions rising to the top and the heavier ones sinking to the bottom and resting upon the screen. The pulsations of the water cause the lighter particles to be raised and washed over into the spout h by the discharge of the water, when they will fall down the inclined bottoms of the spout h and be discharged at the sides of the machine. The heavier portions of the material are moved along over the screen d under the spout h to ward the dischargeopening e, and,there being a clear space over the screen d between the spout h and the discharge end of the machine, the water is free to act upon the material and carry it on toward the dischargeopening c. This movement is rendered more easy and rapid by reason of the fact that the heavy material is relieved of the weight of the superi mposed mass of lighter materials, which are taken off by the spent it before this point is reached. The level and size of the dischargeopening a are regulated to suit the feed of the machine and the proportionate quantity of heavier materials contained in the stock. If
u the quantity of heavier materials is great, the
opening needs to be large and low; butif itis small, the opening needs to be reduced and its level raised, so that a suliicient quantity-is retained on the screen for the proper and effective operation of the machine.
I do not limit myself to the particular form of discharge-trough, nor to making the rear side of the same higher than the front side, as shown, although I prefer that construction, so long as a lateral discharge trough or chute for taking off the lighter materials is provided at a point separate from the discharge end of the machine and above the level of the dischargeopening for the heavier materials, which lateral discharge-trough acts to skim off, so to speak, the lighter materials and prevent them passing any farther in the direction of the discharge-opening. Nor do I limit myself to the particular arrangement of the doors outer end of the screen, and a lateral discharge-trough, open at the top throughout that portion within the jigger and arranged across the jigger over the screen in advance of the disehargeopening, so that there shallbe an open space over the screen between the trough and the discharge end, substantially as and for the purposes described.
2. A jigger having a plunger, a screen, a dischargeopening for heavy material at the outer end of the screen, and a lateral discharge-trough, open at the top throughout the portion which is inside of the jigger and having its rearside higher than the level of the water therein, said discharge-troughbeing arranged across the jigger over the screen in advance of the discharge-opening, substantially as and for the purposes described.
3. A jigger having aplunger, a screen, and a discharge-opening provided with two doors arranged on opposite sides of the opening, whereby the size and altitude of the dischargeopening can be regulated, substantially as and for the purposes described.
In testimony whereof I have hereunto set my hand this 22d day of September, A. D. 1886.
GEORGE LAUDER.
