Application filed February 4, 1924, Serial No. 690,351. Renewed October 13, 1925.

To all whom it may concern.

Be it known that I, lVILLARD N. PACKER, a citizen of the United States, and resident of San Pedro, in the county of Los Angeles, State of California, have invented new and useful Improvements in a Separator, of uhich the following is a specification. This invention relates to a device for operating upon mixtures containing material differing in densities and for separating the lighter from the'hea-vier ingredients. Thus, mixtures of sand and gold or other mineral matter may be separated into their ingredicnts. I

ldore specifically, the invention comprises one or more cylinders which receive the mixture and are'subjected to a planetary motion during which separation is effected.

The primary object of this invention is to provide a structure to function as aforesaid.

Other objects areto provide a structure of the character described which is strong, durable, and requires a minimum of attention.

These objects together with other objects and corresponding accomplishments are obtained by means of the embodiment of my invention illustrated in the accompanying drawing, in which Fig. 1 is a front elevation of a complete machine; Fig. 2 is aside elevation; and Fig. 3 is a section as seen on the broken line 33 of Fig. 1.

Referring more particularly to the drawing, a frame 4 supports the several parts of the machine. Journalled in the top of the frame is a vertical shaft 5, which is fixed at its lower end to a yoke (3. The yoke is journalled on the bottom of the frame and is provided with laterally extending arms 7.

"ixed to the upper end of the shaft 5 is a rzcrel gear 8. llilounted upon the frame 4 at opposite sides of the shaft are bearing standards 9, in which is journalled a shaft 10. Fixed to the shaft is a bevel gear 11 -1neshing with gear 8. so that motion will be and having inturned flanges or'lips 17. The buckets are secured to shafts 18, which are journalled at the upper ends in swivel bearings 19. The lower ends are journalled in the arms 7.

Fixed to the shafts 18 are rolling'gears 20. J ournalled on the arms? and meshing with the gears 20 are idler pinions 21. Meshin g with the pinions 21 is' a stationary base gear 22, which may have a shaft extending through the yoke and fixed to the frame 4. Mounted. uponthe top of the frame and suitably supported by'braces is a delivery hopper 23, from which the mixture may be conducted to the hopper 14. A slide gate 24 controls the flow of material from the delivery hopper'to the receiving hopper.

Themixture which is'to be operated upon is delivered to, the hopper 23, the gate 24 being closed. The machineis now set in oporation by rotating the shaft 10. .This motion is transferred to the shaft 5, revolving the yoke 6 and the cylinder buckets thereon. The base gear 22 being stationary will cause the idler pinions 21 to be rotated. In turn, the movementis transmitted to gears 20, and the buckets 16 are therebycaused to rotate. Thus, the buckets are both rotated and revolved. The motion is a planetary or epicycloidal motion. Due to the idler pinions the buckets 16 are given a rotary motion in a direction opposite to their revolublc motion which causes a rolling of the contents. The gate 24 is opened sufliciently to feed the material to hopper 14 and it passes from the latter through chutes 15 to the buckets. The centrifugal force due to the revolution of the bucket tends to maintain the material at the outer side, and a furtheragitating and centrifugal force is obtained by rotation of the buckets about their 'own axes. The lighter material climbs toward the top of the bucket and finally passes over the flanges 17 being thrown outwardly. The heavier materials remain in the bucket. During the operation the contents are rolled in the cylinders.

It is obvious that the device may be used- Ill) hodiedflin a structtirehavingspur gears and lions nvinvention is gnot limited to such re, ,as .pulleys and belts, sprocket and chains may be subst tuted there- 'toiyso as to, revolve and 'otate the cylinders e, directions claim is:
