To all whom it may concemr Be 7 i known that I, ENooH HENDERSON,

a citizen of the United States, and a resithetable revolves past workmen stationed about the table to pick out the barren rock.

A deflector, which is termed a plow, is disposed above the table in the path of movement of the material being sorted and upon reaching the plow the material is swept from the tableeither tothe inside or to the outside thereof. The plow or deflector, is sustamed in position in amanner to be readily and conveniently displaced where desired and lower rings,

and whereby the inertia of the plow is efiect-ively utilized in preventing accidental displacement'of the plow.,

-'Furthermore, in the preferred form of the invention, the position of the plow relatively to the feed chute is such that the material being received and the material belng swept from the table will act on opposite sides of i the plow to counter-act the pressure at opposite sides. Also, the particular form of the plow in the preferred construction is characterized by'strength and simphcity, and re- 'sults in an effective sweeping of the material from the table. g

' The invention will be particularly eX- plained in the specific description following.

Reference is to be had to the accompanying drawings forming apart of this specification in which similar reference characters indicate the corresponding partsin all the views. A

Figure 1 is a plan view of afcircu-lar table embodying my invention;'Fig. 2 is a transverse vertical section on the line 22,

Fig. 1; Fig. 3 is a detail transverse vertical" section o'n the line 33, g. 1; and Fig. is a transverse verticalsectlon on the line M, Fig. 1.

In constructing a practical embodiment of my invention in accordance with the illustrated example, a suitable base) 10 is pro- Specification of Lettersl'atent.

Application fi1e 1November 1a, 1915. Serial No. 61,343.

vided, having a circular track 11 thereon, on

,which the circular table 12 in the form of a -the plow is arranged to sweep'the material from the table at the inner periphery of the .latterto a chute 16 which may'lead to a crusher or other apparatus or receptacle.

The track 11 is formed with-flanges 17 at each side to receiveseeuring bolts 18, Fig. a. The track 11 has a concave depression 19 1n its upper surfaceand an opposed annular groove or depression 20 is formed in the underside of the table 12, whereby to constitute with the groove or depression 20, an annular race for the balls 13. In practice, the balls 13 are cast iron and are placed in sufiiclent' numbers to substantially fill the ball race.

Thetable 12 is made in the form of upper the lower ring 21 being separately formed and secured to the upper rlng or table top by bolts 23, or the like. Both the upper and lower rings may be formed in any number of segments, there be ing indicated, (see Fig. 1), six segments in each ring, and the segments of the respective ring breaking joint. The lower ring 21 is the narrower and has side flanges 22 to receive the bolts 23. At the inner periphery of the lower ring 21, a depending annular flange 21 is formed to exclude dirt from the ball race and to prevent the axis of the table from moving horizontally which might result in the displacement-of the table from its bearings. i

- The vtable 12 may be given motion 'by any sultable means. In the preferred arrangement, a pinion 24' on m driven shaft 25 meshes with a circular rack 26 cast on the lower ring 21, the said shaft being driven from any convenient source of power. The manner of forming the table 12 with the upper and lower rings enablesme to employ cast iron and the same is true of the track 11 and the ball bearings 13. At the same time any renewal of parts of the table involves the minimum expense. The castings form- 'ing the table and track are rough castings ting these rough castings to be employed vantageously formed of a piece of timber.

On the said timber at the back or outer face thereon, a wear plate 27 of sheet metal is secured to take the wear of the material coming from the chute 14, the said. plow being arranged above the table across the path of movement of the material and oblique to the said path of movement and oblique to the chute 14:. On the face of the timber a shoe 28 is applied, the same being longitudinally curved so as to present its concave side to the path of movement of the' material, as clearly shown in Fig. 1, in which figure the arrows indicate the direction of movement of: the material, it being understood that the table is turned eont'ra-cloclnvise with the arrangement shown, but may be turned clockwise with a reversal of the deflector. At the back of the shoe 28, between the same and the timber a sheet metalplate 29 is provided projecting above the shoe and contributing to the strength thereof as well as forming a wear surface for the front side of the timber.

The inertia of the plow or deflector is utilized in retaining the plow in position and the upper surface of the plow is adapted to receive weights 30, 31. In the illustrated form of the apparatus, the plow is suspended by a series of chains, indicated at 38, said chains being preferably connected with the plow at both ends of the timber and an additional chain at the end of the curved shoe 28. The chains permit the plow 'to be adjusted at any desired distance from the surface of the table 12. There may also be employed guys or tie chains 3%, 35 secured to the plow near each end and fixedly secured at theopposite ends'to any convenient fixed men'ibers or supports. I have shown eyes 36 on the plow to receive the chains 33, there being provided a shackle 37 on the plow at one end to connect with the chains 34, and an eye 38 near the opposite end. of the plow to connect with the chain 35. I prefer to position the plow or deflector 15 adjacent to the delivery chute 14: so that the material will be carried practically through a complete circle before being discharged. Also, in this way, the pressure of the material being carried against the front of the plow will be largely counter-.

turnbuckles 40 or other means for effecting adjustment. Having thus described my invention I claim as new, and desire to secure by Letters Patent 1. An apparatus of the class described,

including a table' in the form of 'a ring and mounted to turn on its ownaxis, means to give a traveling motion to said table on its axis, means to deliver material to the table, and a deflector extending over the ring at,a side thereof across the path of movement of the material carried by the table, and adapted to sweep the material from the table over a peripheral edge thereof, said deflector comprising a beam presenting a top surface adapted to receive weights, the front face of the beam being longitudinally curved, a

shoe secured to the face of the beam and ;path of movement of the material in front of the chute and oblique to the said path of movement of the material.

3. An apparatus of the class described, including a table in the form of a ring, means to give a turning movement to the said table on its axis, a chute for delivering material to the table at one side of the ring, and a deflector positioned at the upper side of the said table and extending across the path of movement of the material in front of the chute and oblique to the said path of movement of the material, the said deflector presenting its concave side at the front to receive the contact of the material carried by the table, the back of the deflector being disposed toward the chute to receive the contact of the-material discharged by the chute.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ENOCH HENDERSON.
