Be it known that'l, lvlARSHAL Henson, a of the United States, residing at Doe i the county of Francois and State i ceding Mechanism, of which the folis a specification. I

e principal object of the resent inven tion is to proride simple, nove andeffective means fer-feeding crushed ore, rock, and the ll 1 to belt conveyeis or other suitable mechems. in every feeder, with which I am acquainted, the material clogs the same, necessitating the services of-a workman to loosen said .material, and r culting in an inter-mitten we; of the same o the belt. EX- pe'rien'oe .as demonstrated that the mechan 'leni herein set forth will not become so clo ged. further and l111101li3ni; object is to provide mechanism, whereby the how may be I readily-altered, as desired, and still another obj ect is-to provide means, whepgby the feeding' mechanism can at anytiine be thrown into and out of operation.

Theoreferred embodiment of the invention is isclosed in the accompanying draw- Figiil'e 1 1s a sideelevation of the same. Fig. 2 is a cross sectional view therethrough. Fig. 3 is a vertical sectional view at right an- :gles to Fi 2. Fig. 4 is a plan view of the 1 carrier ta le. Fig. 5 is a plan view of the 'Ihelt tightener. Fig. 6

Similar reference numerals designate corresponding parts in all the figures of the drawings.

r In the embodiment illustrated, a suitable s u porting frameis employed, comprising port upper beams 10; It is to be understood that any su table sort of frame may be employed. Operating in the lower )QIlliOD. of

= this frame is a conveyerbelt 11 t at passes 3 about a roller 12 suitably journaled in the stringers 8. 3 'AyokeiS extends over the conveyer'belt 11, and has depending legs 14 fixed to the stringers. This yoke supports a central upright journal box 15 havinga lining 1'6 of Babbitt metal, which metal also extends over the upper end of 'thebox, as shown at 17. An'upright,gudgeon 18 is journaled in thebox 1'5, and has ahead 19: that i orn'i,-have invented anew and useful the legs 14 of the supporting yoke 13. p is a detail sectional ,viewonthe line 6fi of Fig. 1.

tably mounted on the portion 17 of the Bebbitt metal. right stem threaded.

A gear wheel 21 cf comparatively great diameter, has a hub 22 located on the stem 20, and resting on the head 19. This gear wheel is furthermore rovided on its upper side with aseries of higs 23. A rotitt'ullle'carrier table 2 1 has a central opening that receives the upper portion of the stem 20, said table resting, on the hub 22 and the lugs 23. A

From this head extends an up v 20, the upper end of which is nut 25, threaded on the upper end of the I stem, serves to clamp the table and gear wheel together and against relative rotation.-

It will thus be seen that upon the rotation of p the gear Wheel, the table will be rotated, said table being in the form of a disk, and its'u per face 26 inclining downwardly from the central ortion to the edges.

For the purpose of rotating the gear wheel 21, and consequently the table 24, the following mechanism is preferably employed. A roller 27 has gudgeons 28 ournaled in 'boXes 29 fixed to the under sides of the stringers 8, said roller being in frictional engagement with the oonveyer belt 11. One.

of the 'gudgeons 28 is provided with s. beveled gear 30 meshingwith a corresponding gear 31 that is fixed to the lower end of an upright countershaft 32 journaled in the boxes 33 of a bracket 3t fastened to one Oof n the upper end of the countershaft 32 is a inion 35, which is in mesh with the gear w eel 21. The shaft 32 can be raised and lowered 'by'means' of a lever 36 fulcrunie'd between its ends and having a yoke 37 engaging in the notches 38 of a-sleeve 39 located on the shaft 32, between collars 40 fixed to said shaft. A holding device 41 serves to maintain the lever:36 in either of two positions. It will be evidentthat by operating this lever, the

shaft can be raised and lowered,-thus carrying the beveled gear 31 into and outof mesh with the gear 30/ A belt tightener for 111-.

suring. frictional engagement between the belt'll and they roller 27' is also provided. This belt tightener consists'of a rock shaft 42 journaledin the stringers 8, and having a lever handle 43 at one e'rid that 006 crates with the holding bracket 44 The roc shaft 42 between the stringers 8 carries a air of crank arms ifithat are in the form o 100 s. These loops engage in slots-46 formed in t e.

I Q I 1 free ends of swinging arms 47 that carry a roller 48. The roller is located between the stretches of the belt 11 and in close proximity to the roller 27. It will thus be evident that if the lever 43 is swung in one direction, the roller 48 will force the belt 11 into frictional engagement with the roller 27, and consequently said roller 27 will be revolved. .If therefore the gears 30 and 31 are in mesh, the eountershaft 32'will be rotated, and as a consequence, the gear wheel 21 and table 19 will be revolved.

The carrier table above described, is surrounded by an upright. circular stationary wall 49 supported by brackets 50, and this Wall at one side is connected to one of said brackets through-the medium of a down-. wardly inclined chute 51 that delivers to the upper stretch of thebelt '11. The wall at one side of its juncture with the chute 51 is provided with a guideway 52, and in the V spout.

same, is slidably mounted a deflector blade or gate 53 that is movable over the upper face 26 of the table, toward and from the axis of rotation of said table. The gate can be held in any desired position by means of a set screw 54 or other suitable device.

Supported on theupper beams 10 of the frame is a hopper 55, and extending, from this hopper is a s out 56 composed of suitable material, suc h as angle iron and sheet metal, said spout being pivotally mounted at its upper end, as shown at 57. The open discharge mouth of'the spout is'covered by a,

swinging closure 58 pivoted to said spout, as shown at 59, and having a link 60 pivoted to 1 The link 60 has notches 61 one of its sides. arranged to receive a lug 62 carried by the Thus the closure may be locked in any position desired with respect to the spout and the mouth, and the size of the mouth can conscquentl be varied to suit the desired amount of feerll The spout has its delivery mouth located over the table and directly in rear of the deflector blade or gate 53, and the table is provided with. a central upstanding boss 63 surrounding the nut 25, and carrying a collar'64 that is tightly fitted. therein. This collar is provided w th upstanding teeth 66, upon which operates a depending lug 67 .earricd by the lower portion of the spout.

The operation of the structure is substantially'as follows: As the table is rotated throu h the medium of the mechanism above table or by bein moved from the table by the deflector. T e amount deposited in the chute can be readily varied by adjusting the blade or ate 53, as will be evident by reference to l ig. 4 The material, falling into the chute 51, will gravitate down the same and be deposited on the upper stretch of the belt. Experience with this machine has demonstrated that it is entirely effective for the purpose desired. It will not choke up, its'feed can be varied as found desirable or necessary, and the mechanism can be uickly thrown out of operation by moving t e belt tightener or raising the countershaft in the manner already described.

From the foregoing, it is thought that the construction, operation, and many advantages of the herein describedinvention, will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
