To a-ZZ whom t may concern.'
Be it known that we, MAX C. SHERMAN, a
Vresident of Cynwyd, in the county of Montgomery and State of Pennsylvania, and
This invention relates to apparatus for handling loose or granular material, and more particularly for storing it and discharging it from time to time. The invention is especially adapted for handling ashes from boiler and like furnaces and in the drawing it is illustrated as adapted for that use.
The object of the invention is to provide means for storing the ashes or other like loose material and for discharging the same from time to time to suitable transporting devices and which discharging means is so arranged as to be easy of operation, to tightly seal the storage hopper or bin, and in which the wearing parts are protectedy from direct contact with the ashes or like material and therefore not subjected to rapid wear or to clogging.
In the accompanying drawings, Figure 1 is a plan view of the lower portion of an ash hopper, together with the gate closing the same and means for operating the gate; Fig. 2 is a vertical longitudinal section taken on the line 2 2; and Fig. 3 is a vertical transverse section taken on the line 3-3, F ig. 1.
The hopper or bin for storing the loose or granular material is indicated at 1, and as illustrated it is a typical form of ash hopper such as used underneath the grates of boiler furnaces in large power plants, the same comprising a suitable metal casing 2, lined with fire brick or other refractory material 3, to protect the metal casing against thel heat of the ashes,.and which hopper is'supported upon suitable beams 4. This hopper at its lower end is provided with a discharge orifice and at said lower end the metal casing is provided with an inwardly projecting flange or ledge 5 for supporting the refractory lining and also with an external flange 6. Underneath the hopper is a casting 7, provided with the discharge opening 8, and at its upper edge horizontal flanges 10 for Specication of Letters Patent.

securing the casting to the flanges 6 of the 55 hopper casing by means of bolts or the like. This casting at its lower edge is provided with the inwardly projecting flange or ledge 11 for supporting the fire brick-or other refractory lining 12, and at the two side edges is provided with outwardly projecting flanges or ledges 13 which form tracks or Ways for the gate or valve supporting means hereinafter described. 'These tracks or ways project'beyond the casting at one end, as shown at 14, to allow for the necessary travel of the gate or valve.
The gate or Valve comprising a rectangular casting 15, lined with lire brick or other refractory material 16, and provided with laterally projecting suspending arms 17, two at each side of the gate, one nearits forward end and the other near its rear end.` These arms 17 project underneath and beyond the tracks 13 and have up-turned end 75 portions 18 which are provided with openings for receiving the journal pins 19 of wheels or rollers 20 which travel on the tracks 13 and serve as the means for suspending the gate or valve. Preferably removable and renewable wearst'rips 21 are provided on the tracks 13-to compensate for any wear which may occur. At both ends of the tracks 13 are upwardly projecting flanges 22, to servevas stops to limit the travel of the gate or valve in both direc tions, these flanges being shown integral with the casting. To permit assembling of the gate on the tracks or ways, the projecting portions 14 'of the casting are provided with holes 23 to permit insertion of the roller journal pins 19.
Connected to one end of the gate or valve, at equal distances from its longitudinal center, are a pair of operating members 24', shown as rods pivotally connected to ears 25 on the gate or valve. These operating rods extend through stationary guides 26 to keep them in alinement and thus overcome any tendency of the gate or valve to become skewed and bind on the tracks or ways from which it is suspended. These operating rods may be connected to any suitable actuating mechanism. As illustrated, the ends of said rods are connected to a crosshead 27, secured to the piston rod 28 of a double acting power cylinder 29, provided with inlets and outlets for the admission and exhaust of any `is not illustrated or described in detail.
Any other suitable mechanism, either power or hand actuated, may be used for reciprocating the gate or valve backwardly and forwardly.
The tracks or ways 13 are at a slight angle tothe bottom face of the casting surrounding the discharge opening 8, and the inclination is such that when the gate is moved to position to close the discharge opening 8, it wedges against the lower face of the casting surrounding said opening, thus tightly sealing said opening, but when the gate is drawn in the direction to open the discharge opening it clears the lower face of, the casting surrounding 'the discharge opening, and therefore can be easily and freely moved. The amount of the in clination of the tracks or ways relative to the bottom face of the casting surrounding the discharge opening is very slight, from it to i in a full sized apparatus, and is therefore not noticeable on the drawings of the scale of those hereto annexed.
Preferably the rear edge of the gate or valve is provided with an edge portion,'pref erably somewhat sharp as shown at 30,
-which serves to shear or break 0H any clinker which ma stick in the discharge opening, upon the ackward or closing movement of the gate.
It will be observed that the tracks or ways from which the gate or valve is suspended are located externally of the discharge opening, and consequently the ashes or other loose material discharged from the hopper cannot get on to said tracks or ways.
a consequence, the tracks or ways remain clean and are not subjected to wear nor can the rollers or wheels become clogged thereon as is the casegwhere the tracks or ways project inwardly and are therefore subjected to the wearing and clogging action of the ashes .or other gritty material. lt'will also befobserved that the Hanges 10 at the upper edgejof the casting 7 project laterally above the tracks or ways, so that external dirt or gritty matter cannot fall upon the said tracks. In these ways the tracks are protected against clogging and excessive wear, so` that positi\'e closure and a tight sealing of the discharge opening can be secured. Furthermore, the rollers or wheels 'are at all times accessible from the outside for inspection, oiling and repairing.
The` operation of the apparatus will be readily understood. By means of the power cylinder 29, or other suitable means, the gate can be reciprocated either direction.
` mechanism for reciprocating said gate.
lVhen moved to the position shown in Fig.
2, it tightly closes the discharge opening, and whenmoved toward the left, viewing Fig. 2, the ashes or other material in the hopper 1..will discharge b gravity through the discharge opening 8, f clinker lodges in the discharge o eliiig it can be Kbroken and dislodgedby forcibly striking the same with the rear edge f the gate.
We claim: v
1. In combination with a hopper provided with a bottom discharge opening, of a frame surrounding said opening and provided on opposite sides thereof with av pairA of outwardly extending flanges spaced vertically of each other, a horizontally movable gate provided with suspendingrmeans extending laterally and upwardly and engaging over the lower one tof said flanges and being overhung by the upper one thereof, and means for reciprocating said gate.
