anism for operating the discharge door of an ore or coal bin.

Other and further important objects of this invention will be apparent from the disclosures in the specification and drawings.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawings:

Fig. 5 is a section taken on line 55, of Fig. 1, with parts omitted.

Fig. 6 is an enlarged view taken on line 6-6, of Fig. 1.

As shown on the drawings:

It will be seen that a plurality of ore bins or hoppers may be arranged adjacent one another, as shown in Fig. 9., and separated a sufficient distance to accommodate the door operating and locking mechanisms of this invention. Since the door actuating mechanisms are identical for each of the ore bins,

'a description of one set of the mechanisms only will be given.

The reference numeral 1, indicates the vertical side walls of an ore or coal bin, pro vided with an inclinedbottom or floor 2, the lower end of which terminates within the bin a short distance from the front end thereof. A front wall 3, closes the upper front portion of the bin, and has the lower part thereof directed outwardly and downwardly to form an inclined plate 4, which, together with the side walls 1, forms a discharge chute the end of which is open to afford a discharge opening for ore, coal or any other material carried in the bin. EX- tending transversely through the lower front portion of the bin is a shaft or aXle 5, journaled in the side walls 1, and extending therethrough to permit a large gear 6, to be secured on each projecting end thereof. Secured on the shaft 5, between the side walls 1, is a feeding cylinder or roll 7, disposed to the front and projecting above the lower edge of the inclined floor 2, as shown in Fig. 3. The cylinder 7, thus located serves as a partial stop for material in the bin.

Rotatably mounted to the outside of each of the side walls 1, is an intermediate gear 8, which meshes with its respective large gear 6. Meshing with each intermediate gear 8, is a small driving gear 9, keyed or otherwise secured on a driving shaft 10, journaled in the bin side walls 1. Also secured on each shaft 10, to the outside of the driving gear 9, is a cam friction disk or eccentric roll 11, having a collar 12, integrally formed on the inner side thereof. An arm or lever 13, is integrally formed'on each of the collars 12, for the purpose of rotating the respective friction cams. A friction driving roll 14, is mounted on a driving shaft 15, to the outside of each bin side wall 1, in a position to be frictionally contacted by the respective cams 11, when the same are rotated by means of the levers 13. The driving shaft 15, projects transversely through the lower rear portion of the bin and may be connected to any desired source of driving power.

Connected to the free end of each lever 13, is one end of a cable 16, which runs upwardly and forwardly and is supported upon a plurality of rotatable sheaves 1'7, 18 and 19 respectively mounted on the outer surface of each of the side walls 1. Sheaves 20 and 21, are rotatably mounted on the under side of a horizontal platform 22, disposed to the front of the bin and having the inner edge abutting the inclined front plate 1. Said sheaves 20 and 21, are respectively disposed at the opposite sides of the bin and serve to permit the cable 16, on one side of the bin to be conducted across the front of the bin and connected to the opposite cable 16, to which a stirrup handle 23, is attached, adapted for sin'rultaneously tensioning both of the cables 16, on opposite sides of the bin. Pivotally mounted on the outside of each slde wall 1, and near the front edge thereof is the upper end of a locking bar 24:, the other end of which is provided with a notch in one corner thereof. Attached to the notched end of each locking bar 2%, is one end of a lock cable 25, which is trained around a sheave 26, and has the. other end thereof connected to the respective cable 16, on that side of the bin, as shown in Fig. 1.

A wei hted quadrant shaped locking member 2 is pivotally mounted to the outside of each of the side walls 1, below the respective locking bars 24. Each locking member 27, is provided with an angled pro- 'jection 28, on the curved edge thereof adapted to engage in the notch of the respective locking bar 2&. A stop 29, is integrally formed on the weighted inner por tion of each locking member. Pivotally attached to each of the locking members 27,

is the upper or inner end of a link or bar 30, the outer or lower end of which is pivotally connected to one side edge of a bin door 31. The door 31, is pivotally supported on the front projecting portions of the side walls, 1, and normally closes the discharge opening of the bin. hen the door is closed the lower edge thereof is positioned to engage against the feeder cylinder 7. Connected to each locking member at the point of pivotal attachment of the respective link 30, is one end of a door closing cable 32, which is trained around rotatably mounted sheaves 33 and 34-, disposed to the inside of the respective sheaves 18 and 19, and shown in dotted lines in Fig. 6. Sheaves 35, are rotatably supported on the under side of the platform 22, adjacent the sheaves 20 and 21, and serve to permit the door closing cable 32, on one side of the bin to be conducted 85 across the front of the bin and secured to the p other door closing cable 32, to which a stirrup handle 36, is attached.

The operation is as follows As clearly shown in Fig. 2, each ore or coal bin, is equipped with a duplicate set of mechanisms mounted on opposite sides thereof adapted to be operated simultaneouslyto equalize the driving and operating stresses applied to the discharge cylinder and the door of each bin. With the parts assembled as shown in Fig. 1, and with the bin filled with ore, coal or any other similar material a truck, dump car or receptacle to be filled with ore is positioned in front of the bin and beneath the door 31 in position to receive ore when the door is opened.

Normally the discharging mechanism and the door operating and controlling means are positioned as shown in full lines in Fig. 1, with the door closed. To operate the ore discharging mechanism an operator or attendant takes hold of the handle 23, and pulls downwardly thereon thereby tensioning both of the cables 16, on opposite sides of the bin and causing the levers 13, to swing upwardly into the dotted line position of Fig. 1. This movement of the levers 13, serves to move the cam members 11, into frictional engagement with the rotating 5 driving rolls 14, which are secured on the driving shaft 15. A drive is thus imparted to the small gears 9, the gears 8, and to the large gears 6. Rotation of the gears 6, causes rotation of the feeder cylinder 7. Ore within the bin falls by ravity and rests upon the cylinder 7, whidh when r0- tated acts to carry ore over the top thereof against the door 31.

As disclosed in Fig. 1, the locking bars 24, are normally positioned to engage the corners 28, of the weighted quadrant members 27, to hold the door 31, locked in closed position. Tensioning of the main cables 16,

however, simultaneously tensions the auxiliary cables 25, connected therewith. The locking bars 24, being connected to the auxiliary cables are thus pulled upwardly out of engagement with the weighted quadrant members 27, which being released permits the force of the ore on the feeder cylinder to move the door 31, outwardly into open position whereby the ore is permitted to be discharged into the car positioned below the door for the purpose. The outward swing of the door 31, is limited by the stops 29, which engage the ends of the locking bars 241-. Opening of the door 31, acts to swing the weighted quadrant members 27, forwardly, thereby simultaneously exerting a pull on the cables 32, and causing the handles 36, to move upwardly into the dotted line position as shown in Fig. 1.

l/Vhen the car below the open door 31, is filled with ore, the handle 23, is released permitting the levers 13, to fall back into normal position and thereby move the cam members 11, out of frictional engagement with the driving rolls 1%. The operation of the feeder cylinder 7 is thus discontinued. The operator then pulls downwardly on the handle 36, thereby tensioning both of the cables 32, and swinging the quadrant members 27, rearwardly until the corners 28, thereof engage the notches of the locking bars 24:. The weighted portions of the quadrant members 27, serve to assist in holding and moving the same into normal looking position. With the return of the quadrant members 27, to normal position a pull is exerted on the links 30, which acts to draw the door 31, into closed position thus cutting off any discharge of the ore from the bin.

It will be noted that pulling on the handle 23, acts to simultaneously release the door locking mechanisms and throw the ore discharging means into operation, as well as moving the door closing handle upwardly into the dotted line position of Fig. 1. The locking bars 24, and the controlling quadrant members 27, co-act to hold the door locked in closed position, and also permit opening of the door and limiting of the outward swing thereof. The mechanisms associated with the bin may be conveniently operated by a single operator or attendant.

We are aware that various details of construction may be varied through a wide range without departing from the principles of our invention and we therefore do not purpose limiting the patent granted further than necessitated by the prior art.
