PATENT DANIEL A. GOODSELL, OF GLEN COVE, NEW YORK.
IVIACHINE FOR SIFTING SAND.
Specification forming part of Letters Patent No. 53,295, dated March 20, 1866.
To all whom it may concern:
Be it known that I, DANIEL A. GooDsELL, of Glen Cove,in the county of Queens and State of New York, have invented a new and, Im- I proved Machine for Sitting Sand; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this speciiication, in which- Figure 1 represents a sectional side elevation of this invention. Fig. 2 is an end view of the same.
Similar letters of reference indicate corresponding parts.
The object of this invention is to effect the tedious operation of sifting sand by machinery instead of by hand, as now practiced.
The invention consists in the employment or use, for sifting sand, of a series of sieves hung in a frame in an inclined position, in combination with a mechanism for imparting to said sieves a shaking motion, and with an elevator in such a manner that by the action ofthe elevatorthe crude sand is automatically raised to the upper sieve, and while passing down over the series of 'sieves it is separated from stones and other impurities that may be mixed with it, and discharged in a state of more or less iineness at the bottom of the sieves orof the frame. The elevator is hung in a vertically-adjustable frame, and it is made to swing on its driving-shaft in such a manner that its position can be accommodated to the heap of sand to be elevated. A screw with hand-wheel serves to adjust the inclination of the sieves according to the state of greater or less dampness in which the sand may be when being sifted.
A represents a frame made of wood or other suitable materal strong enough for the occasion. This frame supports the sieves B,which are hung in the same in an inclined position, as clearly shown in Fig. l of the drawings, their highest end being supported by a strap,which is rigidly secured to the frame, whereas their lowest end is suspended from a hanger, h, which branches oft' from the lower end of a screw, i, that passes up through the end crossbar, j, of the frame A, and screws into a handwheel, 7c, so that by turning said hand-wheel the ends of the sieves are raised or lowered,
and their inclination can be adjusted to suit sand of different quality or of different degrees of moisture.
Said sieves are connected together', and a shaking' motion is imparted to them by the action of an elbow-lever, a, which has its fulcrum on a pivot inserted in a bracket, b, secured to the frame A,and to which an oscillating motion is imparted by an eccentric, d, mounted on the driving-shaft C, and made to connect with one arm of the elbow-lever by a ring and rod, df, or in any other suitable manner.
The driving-shaft C has its bearings in the lower part of the frame, and it connects, by suitable bevel-gears e f and an intermediate shaft, g, with the vertical arbor l. This arbor has its bearings in that end of the frame A which supports the highest ends ofthe sieves, and it extends up through a secondary frame or gate, m, which supports the elevator E. This elevator is constructed in the ordinary manner, with a series of buckets secured to an endless belt, which extends over suitable pulleys in the top and bottom of the elevator.
The requisite motion is imparted to the elevator-belt by a bevel-wheel n, which is mounted on the shaft of the upper pulley of the elevator, and which gears into a bevel-wheel, '0, mounted on the vertical shaft Z of a feather key, so that itis free to move up and down on said shaft together with the gate m. This gate is suspended from a rope, p, which extends over pulleys q to a windlass, r, so that by turning said windlass the gate, together with the upper end ofthe elevator, can be raised or lowered at pleasure. A ratchet-wheel secured to the axle of the windlass, together with a stop-pawl, retain the gate in the desired position. By this arrangement the elevator can be adjusted to any desired inclination, and its position can be accommodated to the location and quantity of sand to be elevated. A spout, s, conducts the sand, after the same has been elevated, to the upper sieve, and by the action ofthe several sieves the iinc sand is separated from the stones, lumps, and other impurities, and it is discharged in the requisite state of iineness ready for immediate use.
The lowest ends of the sieves must be so adjusted that they terminate in different vertical planes in order to separate the parts discharged from each sieve.
By this apparatus the whole operation of elevating and sifting sand can he effected ento the same a shaking` motion, and. with an tirely by machinery, and almost Wholly Without elevator, E, Constructed and operating in the hand labor. manner substantially as set forth.
I claim as new and desire to secure by Letl ters Patent DANL. A. GOODSELL.
The employment'J or use, for the purpose of sifting sand, of a series of sieves, B, in combination with suitable mechanism for imparting Witnesses:
