POWERED-COAL FEEDER. A

Application meea rn 11; 1927. Serial no. 182,730.

trio means and operating in connection with an agitator, between which agitator and bot tom of the hopper holding the powdered coal is a space through which the powdered coal passes, means being provided for. making said space of a less or greater extent, in order to be a smaller or greater amount of powdered coal.

All the features and advantages of my invention will become apparent from reading the following specification and claims.

In the accompanying drawing forming part of this specification: j

Fig.1is a side view of my new coal feeding device,

Fig.2 is afront view,

Fig. 3 is a section taken on Fig. 1, and s Fig. i is a section taken on line H of Fig. 2.

The device is formed of a blower or fan 1, having a base 2, driving motor 3, fan blades 4, secured to a hub 5, which is se curely mounted on a'motor shaft'6.

The blower 1, is joined rigidly by a neck 7 to the side 8, of the housing or box 9. This box or housing carries at its upper part a line 83 of flangelO which is secured to a hopper 12,

this flange is also secured in the housing 9 by cap screws'13. i

Mounted to the side 14; of the box, I have a, cap 15 which carries a bearing 16, and mounted in this bearing is one end of a shaft 17, the other end of the shaft having.

a bifurcated end 18 which engages over a pin 19 secured in the bearing 20, the bearing is connected to the hub 5 of the blower by screws 21. To shaft 17 at its central part, I provide a curved plate 22 which forms an eccentric and is used to engage or-vibrate the shaker wires 23, whenadjusted in a contact relation by the adjusting screw 2a, which has a handle 25 atone end and at the other end is mounted in a cap 26, the cap 26 is fastened to a plate 32 to which the wires 23 I are also fastened. In cap 26 I mount these-t screw 27 which engages groove 28 of'theset screw 24 to prevent displacement.

-As the handle 25 is turned causing the screw 24- to rise upwardly the shaker wires 3 23 will be sprung upwardly also and cause a vibrating or agitation, due to the eccentric plate 22, said agitation being carried'to the trough-like agitator. 29, causing the coal dust to drop or slip through the slotted opening 30. which is in the hopper base 31. I

7 It will be seen from the foregoing description of-the agitating memben'that an adjustment is obtained for feeding the coal dust. If a small amount of coal dust is ,re-

quired the screw 24: is screwed downwardly,

which closes the gap 33between the agitator 29 and the hopper base 31, thereby allowing lesscoaldustto sift through, and in order to get a greater amount of coal dust through opening 30, thescrew 2a is turned upwardly and if a still greater amount is required, the vibration caused by the eccentric plate 22 acting upon the vwires 23, an agitation is caused which will give a greater amountof coal dust. i i

As the coal dust passes through the opening 30 it is drawn through the neck 7 of the blower, which forces it out throughtheopening 34 from whence it is carried to the furnace for ignition.

The blower and the shaft 17 are operated from the motor 3, and the bifurcated end of the shaft 17 is to allow for any variation or disalignment that may be caused in the operation of the device,thebifurcated end 19 and pin 18 provide a flexible shaft or a universal joint, with shaft 6' of the motor.

In order to prevent dirt or dust from get-- ting in flexible shaft joint, I provide felt washers 40, at joint end of shaft 17, and at the other end I provide a spring 43 in hearing 16 to keep end 18 and pin 19 in engagement. Packing 42 is to retain oil in bearing, which is suppliedbv, oiler 41. and a washer A i is for thrust for spring 43 and shaft 17.

In order to further regulate the'feeding of the coal dust, I provide a regulator formed of aplate 35 which is fastened to the side 14 of the housing which plate has openings or ports 36 which are closed by a shutter 37 when desired; this shutter having apin 38 with which to increase or reduce the size of the opening for regulating the draft caused by the blower 1.

While I have described one preferred form of carrying my invention into effect, it will be readily understood that I may modify and change the same somewhat, and I wish to be understood as claiming all such changes and modifications which fall within a the scope of this specification and the appended claims.

What I claim as new and my invention and desire to secure by Letters Patent i1- 1. In a powdered coal feeder, means for holding powdered coal, a shaft suitably supported, an agitator suitably supported within the coal-holding means, shaker rods, a support for said shaker rods at their. lower extremity, at their upper extremity connected tosaid agitator, means for operating against said shaker rods to vibrate them and operate the agitator so that a predetermined amount of powdered coal will fall.

2. In a powdered coal feeder, means for holding powdered coal, a shaft suitably supported, an agitator suitably supported within the coal holding means, shaker rods, a support for said shaker rods at their lower extremity, at their upper extremity connected to said agitator, means for operating against said shaker rods to vibrate them and operate the agitator so that a predetermined amount of powdered coal will fall, and means for regulating the amount or powdered coal to be used.

3. In a powdered coal feeder, a receptacle for holding the powdered coal, having an outlet slot atthe bottom thereof, an agita tor, said agitator in the receptacle and spaced from the bottom thereofand extending through the slot in the receptacle, series of shaker rods, a supporting means for the bottom of said shaker rods, said shaker rods connected at the top to lower extension of the agitator, and means for operating said shaker rods and thus operat ing the agitator so that powdered coal will pass down through the slotted opening in the bottom of the holding receptacle.

nessaoi 4. In a powdered coal feeder, a receptacle for holding, the powdered coal, having an outlet slot at the bottom thereof, an agitator, said agitator in the receptacle and spaced from' the bottom thereof, and extending through the slot in the receptacle, a series of shaker rods, a supporting means for the bottom of said shaker rods, said shaker rods connected at the top to lower extension of the agitator, and means for operating said shaker rods and thus operat ing the agitator so that powdered coal will pass down through the slotted opening in the bottom or" the holding receptacle, and means for moving the shaker rods upwardly and downwardly to increase or diminish the space between the bottom or the agitator and the slot so that a greater or lesser amount of powdered coal will pass through said slot.

5. In a powdered coal feeder, means for holding powdered coal, a shaft suitably supported, an eccentric on said shaft, an agitator suitably supported within the coal holoing means, shaker rods, a support for said shaker rods at their lower extremity, at their upper extremity connected to said agitator, said eccentric shaft constituting means for operating against said shaker rods to vibrate them and operate the agitator so that a predetermined amount or" powdered coal will fall.

6. In a powdered coal feeder, means for holding powdered coal, a shaft suitably supported, an agitator suitably supported within the coal holding means, flexible shaker rods, a support for said shaker rods'at their lower extremity, at their upper extremity connected to said agitator, means for operating against said shaker rods to vibrate the 5211116.

In testimony whereof, I aflix my signature at the city of Cincinnati, in the county of Hamilton and State of Ohio, this 26th day of March, 1927.
