'Applicationv led Hay 23,

One object of my invention is to provide means for carrying away thev water thatisl provide kthe gate, which extends under theV hopper, with gutters for collecting; the water as it eseapesfromfthe hopper, the

water being discharged into a suitable fixed- The invention also relates to certain details oit construction, which will be fully described hereinafter, reference beingl had to the accompanying drawings.

' Referring to the drawings, 1 is an ash hopper of the ordinary type. ring of the hopper. 3 is the casing having a lining 4l of fire brick, in the'present instance. The base ring 3 has a downwardlyextending wall 5 at each side, which each sup.- port one end of a rail 6. The rails 6 are secured to the extension walls 5 by bolts 7 which also extend through spacing blocks 8, as shown in Fig. 3. The opposite ends of the rails 6 are supported by beams 9, which are secured to lateral brackets 10 integral with the extensions 5 of the base ring 2 and to a suitable support son a wall 11, or any other fixed part of a structure in which the ash hopper 1 is located.

12 is the gate of the hopper. This gate 12 is arranged to close the bottom, as shown clearly in Fig. 1, or to be moved to one side of the hopper 1, as illustrated in Fig. 2. The gate 12 is made in the form of a casting hav- 2 is thev base veA'rI: Fon AsH HoPPEHs.

ing longitudinal ribs 13 and transverse ribs ly in Figs. 2 and 3,'to form a substantial surface on which the ashes rest. The flanged wheels 16 are conveniently housed in pockets 17, with the trunnionsthereof located in opposed recesses inthe lower edges of the walls of said pockets. Secured to the outer end of the gate 12 is a4 bracket 18 to which a piston rod 19 is coupled. This piston rod 19 is connected to a piston within a cylinder 2O supportedby transverse beams21k secured to the longitudinal beams 9 by angle bars 9', as shown` clearly in Fig. 3, so that, when fluid under pressurey is admitted to the forward end of the cylinder 20, the pistonl andthe gate 12. to which yit is connected are moved away from the hopper 1 in order that said gate will be drawn to one side ofthe hopper 1 when fully opened, as in Fig.'2, thereby allowing the contents of said hopper to be discharged into any suitable receptacle thereunder, or onto a floor, fromwhieh itis removed by anyl suitable means. When fluid der 22, the gate 12 is moved vto the closed position, as shown in Fig. 1.y The base ring 2 of the hopper 1 is conveniently made'in four sections, ybut it will be understood that it may be made inasv many sections as desired, depending, somewhat, on the size of said hopper. l

When an ash hopper is used, the ashes are usually quenched with water. This water is allowed to drip from the hopper 1, which is objectionable in many installations, especially where said hopper is arrangedover a driveway. In order to collect the water that drains from the ashes'the gate 12 is i provided with a gutter 22 at each side, which gutters are connected by a gutter 23' at the inner end of said gate. .This gutter 23 gradually inclines downwardly from a high point is admitted to the oppositeend of thecylinat the center 24 towards the side gutters 22 l It will be noticed that the side gutters 22- are on an incline, as denoted by dotted lines ink Fig. l, so that the water flows freely from the transverse or end gutter 23 in opposed directions through the gutters 22 to the stationary trough 26.

In some types of hoppers, especially those of larger size, it may be desirable toV close the bottom of the hopper with twoor more gates. p

In Fig. 6, two gates l2 are illustrated,

which close the bottom of the hopper la. The

base ring 2ft has a narrow central partition 28, which is recessed to receive a row of lire brick 29. In addi ion to the side extensions 5a, to

which the rails 6a are attached, a centralex tension 5" depends from the partition 2S and rails 6h are attached to this extension and are Y supported on beams 9". The rails 6 are supported on beams Qn. Two cylinders 20 are used for the two gates l2, said gates being operated in the same manner as a single gate. These two gates l2n`have gutters 22R'and 23"',

' ,not visible, similar to those illustrated in Fig.

l, for carrying oil3 the water that escapes from the ashes in the hopper l.

This construction makes the partition be'-v tiveen the gates very narrow so that practically no ashes remain in the partition when the gates are opened.

I claim: f
