Specification of Letters Patent.
Patented June 25, 1907.
Application filed October 12, 1906- Serial No. 338,563.
This invention relates to sieves for separating, gaging and testing substances such as sand, cement, ores, drugs, or any other substance which the invention is capable of manipulating.
The invention consists in a machine adapt ed for such uses, comprising in the present embodiment a series of sieves of varying mesh superposed and mounted upon asupporting base to which is imparted a motion similar to the gyratory and vertical shaking movement practiced in operating a sieve by hand shaking, this movement being herein referred to, mechanically, as a horizontal gyrating reversing motion and which spreads the contained substance over thesurface of the sieve and an intermittent vertical motion coincident with each reverse movement that produces a succession of shocks or jars and causes the finer particles to separate and pass through the mesh.
In the use of a series of sieves superposed as shown in the present instance, the mesh is of different size beginning with a coarser or larger mesh in the uppermost sieve and in the succeeding sieves employing a gradually decreasing size of mesh, which may be suited to the de ee of fineness desired.
In t e use of the invention any number of sieves may be employed, according to the nature of the substance to be acted upon and the sieves may be transposed or disposed in sets and placed in any relative position found necessary.
In the accompanying drawing forming 'a part of this-specification, a machine is illustrated, embodying the invention in which Figure 1 is an elevation in perspective, Fig. 2 an enlarged front view partly in section, and Fig. 3 a plan or top view showing a relative position of some of the operative parts and the paths of gyration imparted thereto. I
The machine shown is designed to be operated by hand, but any power devices may be substituted.
Referring to the drawing, in which the corresponding parts are designated by the same numerals in each figure, 4 represents the base of the machine to which is secured the supports 5 and 6 upon which the driving mechanism is mounted, comprising the spur gearing 7 with attached handle 8 and beveled gears 910, and through which the horizontal movement of the sieves is transmitted. The vertical shaft 2. of the bevel gear 10 is stepped at its base and rests upon the spring 11 for the purpose "of relieving the jar occa sioned by the intermittent vertical movement of the sieve carrier 12. This vertical intermittent movement of the sieve carrier 12 is produced by the engagement of the bumper 13 depending from its base with the idle rollers 14 attached to the fixed late 15inthe sweep of'the gyrating base of t e carrier. These rollers 14 are located and fixed upon opposite parts of the periphery of the plate 15, and project above the plate to cause the vertical movement of the sieve holder when cont acting intermittently with the bumper 13 The base of the sieve carrier 12 is made in a cup form iron casting having a circular plate or disk 16 set in its bottom and which is allowed to rotate therein through the medium of its grooved periphery, as shown at 17 in Fig. 2. This plate or disk 16 is fixed to the vertlcal shaft 2 eccentrically, as shown in Fig. 2, and the horizontal gyrating movement of the carrier 12 is derived therefrom.
This horizontal gyrating movement of the means of the depending pin 18 which is fixed to the bottom of the carrier and engages with a radial slot 19 in the fixed plate 15, as shown in the respective figures. This pin 18 is moved radially within the slot 19.by the gyrating movement of the carrier, the latter rotating on the pin.
20 represents vertical tie rods arranged upon and fixed toopposite sides of the base of the sieve carrier and which are provided with screw hand wheels 21 at the top, these rods serving in connection with a top plate 22 to in'close and hold any number of the series of sieves in place.
The movement of the various operative parts of the machine will be readily understood by an inspection of the drawing, the horizontal movement of the sieve carrier being derived directly through the connected gears and the gyrating reversing motion derived from the rotation of the eccentric disk located in its base, the latter being guided and controlled by the depending pin and slot engagement as heretofore described.
The various positions assumed by the sieve carrier during its horizontal movement are indicated in the dotted lines 232425 in Fig. 3.
hat I desire to claim and secure by Letters-Patent is a In a self-contained shaking bolt the combination with a series of superposed and interchangeable sieves, of a carrier having a horizontal gyrating reversing movement on the vertical shaft 2 by means of the engagin circular disk 16 fixed eccentrically to sai shaft; a vertical intermittent movement at eachgyration by-means of the bumpers 13 and engaging rollers 14; a supporting base beneath said carrier inclosing the transmitting operating devices for effecting the said movements, and a connected power device for operating the same.
In testimony whereof a'fiix my signature in presence of two witnesses.
