Application filed February 14, 1913.

To all whom it may concern: 7

Be it known that I, HENRY F. LAMB, a citizen of the United States, residing at Bellingham, in the county of VVha-tcom and State of Washington, have invented new and useful Improvements in Separators, of which the following is a specification.

My invention relates in general to separators and has particular reference to that class of devices peculiarly adapted to separating sand from gravel or extracting the finer elements from the coarser ones in any similar substance.

The principal object of my invention resides in the provision of means whereby the separated elements may be individually conveyed to vats, containers or similar structures.

The above and additional objects are accomplished by such means as are illustrated in their preferred embodiment in the accompanying drawings described in the following specification and then more particularly pointed out in the claim which is appended hereto and forms a part of this application.

With reference to the drawings throughout which similar reference numerals designate corresponding parts: Figure 1 is a front elevation with portions of the box broken away to more clearly disclose the assembled relation of the various parts. Fig. 2 is an end elevation. Fig. 3 is a section on the line 33 of Fig. 1.

Proceeding now to the description of the drawings my invention includes the separator box designated as an entirety by the numeral 1, the conveyer chute 2, the outlet pipes 3 and 4, the worm 5, the screen 6 and the agitating cams 7.

The box 1 is constructed according to the common practice and may be angularly supported by any suitable means. Hingedly mounted at the upper end of the box is the worm housing 8, on the upper portion of which the conveyer chute 2 is seated. The housing 8 is provided with the hinged door 9 whereby access may be had to the worm 5 in the event that the mechanism becomes clogged by the gravel. A door 10 is also carried by the housing 8 providing access to the interior of the box 1. Spaced from the lower end of the box and held in rigid relation thereto is the division wall 11 which may be suitably braced by the members 12. The pipe 3 communicates with the chamber Specification of Letters Patent.

formed by the spacing of the wall 11 from the lower end of the box and a pipe 4 is in communication with the upper chamber of the box.

The worm 5 is rotatably mounted within the housing 8 and is disposed to evenly distribute the incoming gravel along the upper portion of the screen 6. The baffle shelf 13 is secured to the wall of the housing by the brace 14 and co-acts with the worm!) in the distribution of the gravel. The screen 6 which is of the common type and is provided to permit the finer portions of the gravel to sift through into the upper compartment of the box, is secured at its lower end to the upper edge of the partition wall 11 and is pivotally connected at its upper end with the shaft 15 through the medium of the connection 16. The screen 6 carries on its under side the longitudinally extending series of plates 17, 18 and 19. Secured to the plates 17 and 19 are a plurality of helical springs, the lower ends of which are fixed to the rod supporting plates 20. The plates 20 carry the stop rods 21 which are mounted within the spring and are adapted to engage the members 17 and 19 when the screen is forced toward the wall of the box by the weight of the gravel.

In order to thoroughly separate the sand from the gravel, it is desirable that the screen be continuously agitated and to accomplish this result I employ the cams 7. These members are keyed to the rotatable shaft 22 and are disposed for engagement in their rotation with the plates 18. The cam consists of a circular disk 23, having a plurality of strap members 24 secured thereto.

The above disclosures clearly explain the construction of my invention and 1 now pass toa brief explanation of the operation of the separator.

The gravel is introduced into the box through the chute 2 and falls upon the worm and shelf at the adjacent end thereof. The gravel is distributed by the Worm evenly along the upper portion of the screen and then passes by the force of gravity along the inclined surface of the said screen. It will be seen however, that if the shaft 22 is connected to the same means employed for rotating the worm, the screen will be given continuous agitations by the action of the strap 24. against the plates 19. The effect of this agitation will of course be increased by the springs 20. As a result of the agitation of the screen, the finer elements of the gravel Will fall into the upper chamber of the box and will pass out through the pipe 4 While the coarser elements Will continue along the screen and drop into the loWer compartment of the box subsequently passing out through the pipe 3 whence they may be conducted to any suitable container. In this connection it Will be understood that While I have described my invention as being peculiarly adaptable for the separation of'sand and gravel, it may be also employed in separating the coarse and fine elements of any substance; and that While I have described the pipes 3 and 4 as leading to containers, it

Will be seen that the box may be readily mounted in such manner as to permit the sand and gravel to fall Wagon.

It Will be further understood that various minor changes in details of construction and arrangement of parts may be made Within the scope of the appended claim and Withdirectly i'nto a out sacrificing any of the advantages of this invention.

What is claimed is:

'. A separator comprising an inclined housing having an opening in the upper end thereof, a vertical housing hingedly con nected to the inclined housing and covering the opening therein, a conveyer leading into the top of the vertical housing, a conveyer screw rotatably mounted Within the vertical housingibeloW the conveyer, a rod extending the inclined housing near the loWer end thereof, cams carried by said transverse shaft and adapted to engage the contact the screen, a shaft extending transversely of plates on the screen, a partition secured in the vertical housing adjacent the lower end of the screen, and outlet chutes leading from said inclined housing at each side of the partition.
