ASH GATE.

Original application filed June 28, 1922. Serial No. 571,404. Divided and this application led December 28, 1923. Serial No. 683,104.

To all whom it may concer/n:

Be it known that I, FRANK B. ALLEN, a citizen of the United States, residing at Cynwyd, in the county of Montgomery and State of Penpsylvania,.have invented certain new and useful Improvements in Ash Gates, of which the following is a specification.

My invention relates to hopper construction, particularly to construction of the bottom portionl of hoppers having bottom discharge openings, which portion is commonly called the gate It especially relates to gates for such hoppers which are to receive the ashes from large heating units. It also relates t'o so-called gate construction for hoppers having two or more spaced bottom ldischarge openings.

For the purpose of this specification the term gate is understood to mean the structural parts comprising the bottom portion of a hopper of the type. above described and including, among other parts, (l) a stationary member surrounding each discharge opening in the hopper bottom and constituting more or less denitc parts of the downwardly extending hopper walls, t 2) a movable door for each discharge opening, and (3) a frame for supporting and means for operating the doors.

One object of my invention is to construct a hopper gate comprising stationary members -tor two or more discharge openings, a frame for two or more stationary members having portions adapted to serve as tracks for door-supporting wheels and a door 'for each opening.

Another object is to construct a hopper gate having a door provided with longitudinally unaligned supporting wheels, and a trame having inner and outer portions adapted to serve as tracks for the unaligned door wheels.

Another object is to construct a hopper gale frame having inner portions between r adjacent discharge openings which serve as rails 'for the wheels on the rear or adjacent ends of the doors for such openings and other outer portions'which serve as rails for the wheels on the front or remote ends of such doors.

Another object of my invention is to pro-J vide downwardly projectin nozzles on the stationary'niembers to whic a hose may be attached for the purpose of washing out any ashes or clinker.` that may have found their way into and remained in the troughs.

Another object of my invention is to provide a simple and yet rugged ash gate construction such that the stationary members and frame may be built as a unit and combined with an operating cylinder thereon for the doors, so that when completed the whole unit may be shipped from the point of manufacture to the place where it is to be attached to the bottom of an ash hopper to which it may be bolted or secured in any suitable manner.

Another object of my invention is to rovide other details of improvement tending to increase the efficiency and serviceability ot'an ash gate of the above described character.

To accomplish the foregoing and other yuseful ends, my invention makes use of means hereinafter more fully set forth and claimed.

Referring to the accompanying drawings:

Figure l is a top view of one form of gate embodying my invention.

Fig. 2 is a side view in elevation and partly in section of the gate shown in Figure 1, the section being taken on line 2 2 of Figure 1.

Fig. 3 is an end view in elevation, partly in section, of the gate and lower part of the hopper, the section being taken on line 3-3 of Figure 1.

Fig. 4 is a sectional view of the gate taken on line 4--4 of Figure 1.

Fig. 5 is a top view of the dor` Without the frame and showing the troughs on the door and the stationary trough.'

Fig. 6 is a view of the door and stationary trough taken on line 6--6 of Figure 5.

Fig. 7 is a sectional viewtaken on line 7-7 of Fig. 5.

Referring more in detail to the drawings, and more particularly to Figure 1, it will be seen that the frame has two

main irders

2 and 3, forming the longer sides of t e gate frame which girders are connected near the middle by the cross ties 4 and 5. The ends for each hopper discharge opening, which in the form shown are each composed of a cast iron casting. The inner side walls 8a of member 8 constitute the bottom portions of the downwardly extending hopper` walls about' the discharge openings as shown in Fig. 3 and co-operate with-doors 9 and 10 to form a substantially ash-tight closure for the opening. l

Each of.y the doors 9 and 10. is provided with two /sets of wheels, one set being an inside set/ and the other being an outside'set, with respect to the framestructure. The inside set of wheels are the wheels 11, and the outside set are the wheels 12. The wheels 12 are arranged to run on outside flanges 13

ofmeinbers

2 and 3 respectively while the inside set of wheels 11 are arranged to run on an auxiliary set of flanges 14. These fianges 14 are parts of angle iron pieces 14a which are' located on the inside of the frame, see' Fig. 4. These angle iron pieces 14a are only long enough to cover the space necessary to accommodate the inside wheels of the door 10, and the inside wheels of the door 9. It will bennderstood, of course, that the door 9 has likewise its inner sert of wheels 16 and its outer set of wheels 1 The method of mounting the Wheels 11 and 16 is shown in Fig. 4. Suitable spindles 23 are secured to the rear ends of the doors uponwliich spindles the wheels 11 and 16 are suitably mounted to rotate.

The Wheels 12 are mounted a little differently. A suitable arm 24 is secured to the lower art of the front end of door 10, Fig. 3. This arm has a rejecting portion that passes under thel gir er 3, it being cutaway as shown in Fig. 3, for this purpose. On the right hand of this arm a suitable spindle 25 is clamped to the end of the arm 24 by means of bolts 26. On this spindle the wheel 12 is secured to rotate. It will be seen that the Wheel 12 is on the inner side of the spindle securing bolts 26 and rolls along the ange 13 of the irder 3.

On the opposite side o the door there iS another arm 27 similar to the arm 24 on which the other wheel 12 is similarly mounted. It will be understood that the wheels 17 are similarly mounted on arms under the door 9, similar to

arms

24 and 27, and that the wheels 12 and 17 run on fianges 13 of

members

2 and 3.

, a trough 18.

door 10 may be opened as shown in Fig. `2, the piston being indicated at the extreme end of its stroke, by operating the piston in a reverse direction the door 10 may be closed.

ln the operation of the door 10, the wheels the door 9 innst be closed or substantiallyso, and rice versa, dueto the limited space between the openings.

Since doors 9 and 10 are alike in substanrtially all respects only one will be described in detail. Door 10 is formed with upstanding flanges or projections 10n within which lining bricks or material (not shown) may be positioned. Along the opposite sides and rear end 10` the door is extended laterally and provided with npstanding flanges 10b which extend above the top of fianges 10"L and the top of the door proper, all as is clearly shown in Figs. 1, 3, and 6. Also, as will be noted from these figures, the flanges 10b extend above the bottom edge of inner side walls 3a of stationary membcisS. Flanges 1()n and 10b co-operate to forni troughs along the rear end 10d and opposite sides of the door, the rear end trough being connected with `the side troughs, for example, by enclosed passages 19c coi-ed out in the rear corners of the door. The troughs thus formed constitute, when joined together, a channel which has been designated on the drawings as 19, and which is adapted to collect liquid passing through the hopper and off the three sides of the door and to conduct such liquid to the front end 10n of the gate where it may be discharged into The channel 19 preferably has the highest point. of its bottoni wall along the rear end of the door, as at the point indicated by20 in Fig. 4. From this point the bottom wall of the end trough slopes or iuclincs downwardly toward each side trough A and B as shown in Fig. 4, and the bottoin walls of troughs and B each slope or incline downwardly from the end trough toward thel frontend of the door, as is clearly shown in Fig. 7.

These side troughs and B terminate in forwardly and downwardly projecting spouts 22, which are located above the trough 18 when the door is in closed position with respect to inernb'er S and the hopper discharge openinv'.

Projecting down from the upper side of the stationary member 8, Figs. 1 and 2, I providc'a nozzle 33, which is located at an angle sloping in the direction of the trough 18. The object of this nozzle is to enable a hose or :similar means connected to a source of water under pressure to communicate iii) T im y aving thus described a practical-emboditherein.

with the nozzle orthe Jurpose of scouring out the side troughs in t e door in the event that ashes or other material accumulates rIhere .is one such nozzle on either side of the member, one for the trough A and another for the trough B. A similar set of nozzles are provided for the other door.

H'It will be understood that any number of these nozzles may be located anywhere above `the trough 19 or stationary trough 18.

A gate of this construction is rugged 'and rigid. It is a complete unit, may be assembled at the factory and as a unit picked up by a crane without any danger of warping or breaking. It may then be conveyed to the plant where the ash hopper is located. and bolted into position, as indicated in Fig. 3. Some oI" the bolts Vby means of which the frame is bolted in the ash hopper 34, Fig. 3, are long enough to extend from the flange 13 up to the flange 35. Other of the bolts are shorter. Along the

girders

2 and 3, suitable brackets 36 are provided and bolts are used to fasten these brackets to the flange 35. The

brackets 36 are o course suitably riveted to the

girders

2 and 3.

It will be noted that I have provided an `ash gate of simple yet durable construction,

which can be assembled as a unit and shipped to the place of installation and yet a construction which contains no unnecessary expensive lparts and may be cheaply manufactured. Y It will be observed that the arrangement of wheels on the ash doors is such that they are all protected from contact with' ashes. The wheels 12 and 17 which travel past the ash discharge openings are on the outside tracks and thoroughly protected :from ashes while the wheels 11 and 16 do not pass the ash openings and may therefore operate on inside tracks, since these tracks do not extend beneath the openings and therefore canstantially straight or when they are covered for part of their length ashes may lodge in the troughs and interferefwith' or entirely stop the flow of water therein. In my'deor however the troughs are wide, straightand open for the full width and length thereof insuringa ainst lodging of material therein and provi ing easy accessibilityr for cleaning. The spouts 22 at'the ends ot-troughs A and are short and easily accessible for cleanand may be made of such size that no 1n y* soid material from the troughs will stop or them. l

ment of my invention, so that others skilled in the art may practice the same, what I desire to secure by Letters Patent is defined in the claims, it being understood that changes, alterations or modifications not involving inventions lnay be made in the'structural details and parts herein shown, without departing from the spirit- .and scope of my invention.
