HYDRAULI C SYSTEM FOR HANDLING ASHES AND THE LIKE Original Filed Feb. 8, 1925 2 Sheets Sheet 2 I ATTORNEY Patented Apr. 19, 1932 UNITED STATES PATENT OFFICE THOMAS E. MURRAY, BROOKLYN, NEW YORK; JOSEPH BRADLEY MURRAY, THOMAS E. MURRAY, JR., AND JOHN F. MURRAY, EXECUTORS OF SAID THOMAS E. MURRAY,
DECEASED, ASSIGNORS TO METROPOLITAN TION OF NEW YORK ENGINEERING COMPANY, A CORPORA- HYDRAULIG SYSTEM FOR HANDLING ASHES AND THE LIKE Application filed February 8, 1923, Serial No. 617,669. Renewed January 18, 1930.
My invention aims to provide an economical and efficient apparatus designed particularly for handling ashes and the like from the furnaces of powerhouses and other structures where such material accumulates.
The accompanying drawings illustrate an embodiment of the invention.
' Fig. 1 is a side elevation partly in sectlon;
Fig. 2 is a longitudinal section broken at intervals;
Fig. 3 is a cross-section approximately on the line 3-3 of Fig. 2,;
Fig. 4 is a longitudinal section of one of the removable wear plates and the cast iron trough;
Fig. 5 is a cross-section through the trough at a point indicated by the line 55 of Fig. 2.
The ashes are carried by a stream of water down an inclined trough into which they are dropped at intervals from the various ash pits served by the apparatus. The trough is composed of cast iron sections 1 bolted to gether by means of transverse flanges 2 at their ends and having also flanges 3 on its longitudinal edges by which it is supported from a structure hereinafter described.
This cast iron trough is provided with a removable and renewable liner composed of cast sections 4 with overlapping joints 5 (Fig. 4) alternating with the joints of the sections 1 which form the permanent body of the trough.
The trough is'arranged between columns 6 at opposite sides, which may be the columns of the building carrying floor girders 7. A hopper 8 is indicated with spiked rollers 9 which break the cinders and regulate the feed of the ashes from one of the pits to the trough. Between the lower ends of the columns 6 is a framework of beams 10 supported by struts 11 and 12 and supporting flanged cast iron plates 13 and 1.4 which are lined with concrete and form diverging upward extensions from the sides of the conveying trough. The sections 1 of the trough are fastened to and suspended from the lower longitudinally inclined edges of these plates 13 and 14, as indicated in Fig. 3. The sides 13 and 14 and the columns 6 also carry plates 15 and 16 and these plates, together with the girders 7 form to the hopper 8, and are preferably lined with concrete as shown.
At one side openings are provided for securing access easily to the trough to clean it or repair it, or to release any accumulation which may choke it. For this purpose the plates 14 are provided with man holes 17 provided with covers 18, of cast iron lined with concrete, which are hinged at their lower edges and arranged to swing inward. In the closed position, Fig. 3. such doors are held in place by gravity. When access is desired to the trough, the door can be pushed open, its downward movement being preferably limited by the chain 19. Such doors may be arranged continuously or at frequent intervals, one in fact for each section of the trough as shown in Fig. 1. Or they may be placed at less frequent intervals.
At the upper end of the trough it is closed by an end wall 20, Fig. 2, bolted at its lower edge to the flange on the uppermost trough section 1 and formed with an opening registering with the bottom of the trough through which a strong stream of water is directed from a pipe 21. The water conveys the ashes down the inclined trough and out through a larger exit pipe to the lower end wall 23.
Ordinarily the stream of water will fill the trough approximately to the upper edge of the iner 4. as shown in Fig. 5, and the inclination will be such as to create a current switch enough to carry off the ashes. Where a long trough has to be installed with a comparatively short drop from one end to the other, I propose to provide boosters at intervals in the stream. These may consist for example of nozzles 24 pointing down stream and supplied with water from pipes 25. The trough itself may have a drop from a higher to a lower level at this point, so as to bring the mouth of the nozzle as shown substantially in line with the lower portion of the trough. These boosters may be placed atintervals depending on the inclination and the volume of water and the character of the ashes or other material to behandled. They sidewall extensions of the trough clear up are preferably placed adjacent to the points where the supply of ashes is deposited in the trough. Even where the conditions are not such as to require a constant use of boosters of this sort they may be provided for emergencies and equipped with valves 26 and may be opened only in case of a blocking or choking of the trough to give an extra force to the stream. a 5 The complete apparatus is substantially dust proof. In case of emergency on account of choking of the trough it can ordinarily be restored to proper operation by opening one or more of the boosters referred to. Or if this is not sufiicient a workman can easily get into it and breakup any stoppage. By replacing the liners or wear plates 4: from time to time, the necessity of any extensive stoppage for repairs is obviated. These liners are removed by merely lifting them out of place between the plates 13 and 14, which are spaced apart sufficiently to permit this, as shown in Fig. 5.
Though I have described with great particularity of detail a certain, specific embodiment of my invention, yet it is not to be understood therefrom that the invention is restricted to the particular embodiments disclosed. Various modifications thereof in detail and in the arrangement of the parts may be made by those skilled in the art without departure from the invention as defined in the following claims.
