'useiiul Improvements in Receptacles for A hesand the like, of which the following is a specification.

This invention relates to improvements in the construction of receptacles, and particularly to receptacles or storage tanks suitable for-the collection and disposal of ashes and theli'ke; Receptacles of the character described are ordinarily installed in connection with v "{Lpnc'umaticyash: conveying systems, such as "rc commonl for the hzindling and ref' ov'al of as es in large boiler plants, the

ashes being carried in closed conduits from the furnaces to an elevated receptacle or disposal tank, preferably situated exterior to the boiler house and in such place as to permit its contents into cars or wagons mate disposal.

The supporting frameor structure 10 is preferably of steel, being made up of members or structural forms known as anglebars arranged in the following manner: At the corners of the frame are vertical posts or columns 16, mounted upon suitable foundations at their lower ends and extending upwardly a distance sufiicient to permit the location of the receptacle at the desired eleration above the ground. The corner posts have the cross-sectional contour of the usual angle-iron or bar, the webs thereof being disposed at an angle of 90 to each other and coinciding with the sides of an imaginary rectangle indicating the outline of the frame. The upright columns or posts 16 are joined together by the following arrangement of cross-beams or struts.

Througlrbut the lower portion of the frame a preferable arrangement {comprises horizontal strut members 17, extending between each post, and. immediately above the same, pairs of intersecting tension members 18, 18, joined together at their mid point by a plate 19, there being provided a similar arrange ment on each side of the frame. Throughout the upper portion of the frame there is provided a distinctly different arrangen'ient of members as follbws: Surrounding the upper end of the frame is a plurality of'hori- Zontal angle-bars 20, which-extend between and are connected to the web of each of the corner columns 16, said angle bars being arranged so that one web thereof abuts flatwise against the outer surface of the webs of the columns, and the other webs project outwardly and horizontally from the lower margin of the vertical web. Below the angle-bars, 20 are a plurality of other anglebars 21, somewhat smaller in size, but otherwise connected to the corner posts 16 in the same manner as the bars 20, the same being spaced apart vertically at equal distances and arranged in parallel relation to each other and to the angle-bars 20. As shown in Fig. 1, there are three seriesof the smaller angle-bars 21, which form in effect a series of bands, which surround the outer surface of the supporting structure. Spaced below the lowermost series of angle-bars 21 is another series of anglebars 22, somewhat larger in size than the angle-bars 21 and substantially the same size as'the angle-bars 20. said series of angle-bars 22 being arranged parallel to the bars 20 and 21 and connected to the frame. structure 16 in identically the same manner as are the bars 20.and 21.

The parts thus described constitute the rigid and permanent structure which sup ports the receptacle proper, which will now be described in detail, referring first to the manner in which the side walls of the recep tacle are formed, it being understood that the description of one side wall will suflice for all.-

In general, the side walls may be said to comprise a plurality of wall sections or units, which are removably attached to the supporting frame, to wit, to the horizontal bars 20 and 21 thereof. These units or sections are of two varieties, namely, vertically depending bars 23, which are supported upon the supporting frame, and a plurality ofplates 24 supported by said bars, said bars and plates being arranged in rows or tiers, one above the other and extending through out the height of the side walls, each row or tier being supported upon one of the series of cross-bars 20 and 21, and having overlapping engagement With the row immediately below, as will hereinafter be described in detail.

The bars 23 are preferably of cast iron and comparativel; 1 arrow in width and of a length substantially equal to the distance between the horizontal frame. members 20 and 21. Said bars 23 are provided along their opposed lateral surfaces with longitudinally extending grooves 25, 2F, and at the upper end of each bar is provided a hooked extremity 26, projecting beyond the end of the bar and transversely thereof. These bars are attached to or suspended from the horizontal frame members 20 and 21 by means of the hooked extremities 26, which engage the vertical flanges of said members and hang downwardly therefrom and upon the inner side thereof, said bars being arranged in series, as before suggested, extending along each of said horizontal members in parallel and spaced relation and terminating adjacent to the upper end of the series or tier of like bars which are suspended from the cross-bars 21 immediately below, the bars of each series or tier being in vertical alinement with'a corresponding bar of the seriesimmediately below, so that all of the bars 23 present the appearance of vertical members extending throughout the height of the side walls of the receptacle. Referring to Fig. 6, the exact arrangement of the bars 23 is clearly shown: Each bar extends downwardly end of the bar immediately below, the lower end of the uppermost bar engaging the end surface of the lowermost bar and resting in a recess formed by said end surface and the rear surface of the hooked extremity 26. Thus each bar is slightly inclined, itbeingoverlapping the upper being of any desired width and of a lengthy substantially equal to that of thesaid bars,

namely, of alength equal. to the distance between the supporting cross-bars or Q1. The plates are supported by the bars through the medium of the grooves 25, which. engage the lateral-margins of said plates, the same being inserted between and into the grooves of two adjacent bars 23, preferably from the upper ends thereof, each plate or wall section thus closing the space between two adjacent bars 23 and between two adjacent cross-bars 21 or 20. Each row or tier of plates 24:, thus formed, extends completely around the receptacle, each plate or row of plates terminating substantially flush with the plate or row of plates immediately below. Inasmuch as the grooves in the bars 23 ex tend throughout their length, it is desirable to provide means for limiting the downward movement of the plates with relation to the bars Q3. This is preferably accomplished by provilding at the upper end 02 each bar 23 a depression 27, located upon the inner edge of the bar and adjacent to the lateral groove 25 (Fig. 5 The plates are provided with inwardly projecting lugs 28 located along" their upper margin and. at the outer end, said lugs being adapted to enter the den sions and to prevent further d: uiward movement of the plates, thus when isinserted the same will extend tl full length of the bar and at the same time have its upper margin flush with the end surfaw of the bar. It is to be also noted that, in inserting the plate, its lower margin will abut against and rest upon the upper end surface of the bar immediately below, as is clearly shown in Fig.- 6, thus normally re-- taining the plate in position, although it is to be noted that, were several bars swung inwardly, the intermediate plates would be released and drop downwardly, hence the provision of additional plate-retaining means is desirable.

At the corners of the receptacle a slightly dififerent construction of the wall section is employed, as is clearly shown in Figs. 2 and l. At each corner is provided a member 30, which has the form of aplate or member 31., provided along its vertical margins with-err larged portions 32, 32, arranged at an angle to the WebBO, said enlarged portions being provided with longitudinally extending grooves 33, similar in ,all respects to the. grooves in the bars 23 located intermediate:

the-corners." At the upperqends of thegen larpjed portions are provided hooked extremities 34:, identical with. the hooked mem bers 26 of the bar members 23, said hooked members being arranged at an angle of 90 to each other and substantially at an angle of to the web 31. The purpose of the corner members 30 to provide a method for bridging the corner posts 16, and in reality they consist of two bars 23, which are connected together by an integral oblique web 3]. extending between them, said web forming the corner wall portion of the re ceptacle immediately inside of the webs of the corner posts 15. In other respects the corner members 30 perform the same functions as the intermediate members 23 and,.in addition, form the corner surfaces of the re ceptacle in place of removable plates such as are used intermediate the corners.

The construction thus described provides a. side wall consisting of a multitude of small units in theform of supporting bars and plates or wall sections, which are capable of removal from the supporting 'frame and of being; disconnected from each other, each plate or bar being a separateunit, which can be removed without materially disturbing the remaining units or sections.

Referring now to the manner in winch the top wall 13 is formed, it is to be observed that the unit or sectional construction is ad the receptacle, their of recesses or notches 36, which receive the hooked extremities of the uppermosttier of grooved bars of the top plate or cover members BX- tend obliquely to the side walls at an angle.

This rectangular opening is, in turn, partially covered by means of? still. smaller triangular men1bers'37 ,having the same shape as the members 35. These mmnbers zire arranged obliquely of said 1uemln-u's-35, their-longer margins extending at an angle of 45 to the corresponding edges of suit members 35, and form a rectangular open? 125 ing still smaller? in its dimensions. Th shorter or lateral margins of the plates 37 .feverlapand rest upon the edges of the cover -1heinbers'35, the latter being provided along The longer margins Y eir inner; edges with upwardly projecting ribs 38, 38, located a short distance inwa-rdlx' from their margins, said ribs forming aribs 41, which. act, as before described in connection with the ribs of the plate members 351, to retain the triangular members 40 in position. The rectangular opening formed. by the inner margins of the triangular members 4 is again partially closed by means of still smaller plate members 42, which overlap the margins of the plates 40 and are held in position by ribs 43, extending along the margins of the plate members 40, said plate members 42 being formed to pro vide a circular opening having substantially the same diameter as the rectangular opening formed by said plates 40. The circular opening thus formed is preferably surrounded by a flange 44. -,Into this circular opening projects the end of a pipe 45, through which the ashes or like material enters the receptacle from the conduits of the conveying system which the receptacle serves.

Referring now to the construction of the remaining part of the receptacle, namely the bottom wall or lower portion, the same comprises, in general, frame members rigidly connected to the supporting-structure, other frame members removably attached to the frame structure, and removable wall sections attached to the permanent as well as the removable frame members. 'I'Referring' more in detail to the arrangement .of these members, which formthe tapered or convergent lower portion of the receptacle,

there is rigidly connected to each of the 'vertical column members 16 of the supporting structure a frame member 46, extending downwardly and inwardly and forming the corners of said lower portion, said members terminating at their lower ends in close proximity and there connected to the discharge passage 15. The frame members 46 consist of V-shaped angle members having webs arranged at angles of 90 to each other and preferably connected to the vertical column member 16 of the supporting frame in the following manner: Rigidly attached to the inner surface of each vertical column member 16 and adjacent to the lower por tion of the side wall of the receptacle is a bracket 47 (Figs. 8 and 9), said bracket comprising a. base portion 48 consisting of webs adapted to abut fiatwise against the inner surface of the column member 16, and an inclined portion 49, integral with the base portion and projecting from a point substantially midway of the length thereof in a downwardly andtinwardly inclined di- 'rection. The inclined portion is V.-shaped in cross-section and forms a seat, in which rests the upper end of the frame members 46 of the lower portionlor wall of the receptado, said members 46 being preferably connected to said inclined portion 49 by means of rivets 50.. As before suggested, them'embers. 46 are connected to the discharge passage 15, the same being provided about its upper margin with an outwardly flaring flange 51-, to which are attached the lower extremities of said inclined frame members 46 by means of rivets. Along the outer margins of the frame members 46 there are provided longitudinally extending grooves or rabbets 52 formed in the inner surface of the Webs thereof, said grooves or rabbets being adapted to receive the margins of the sectional wall members, as will hereinafter be pointed out. Intermediate the rigidly connected frame members 46 are provided a plurality of removable frame members 53 and 54, said removable frame members being preferably arranged in a series of three each, each series being located on each of the four sides of the lower portion of the receptacle. These frame members consist of bars having the form shown in Fig. 7, namely, twointersecting webs 55 and 56 arranged at rightv angles to each other in a manner resembling a cross. At the upper end of each bar 53 and 54 is provided a hooked extremity 57 (Fig. 6), adapted to engage the vertical webs of the horizontal frame members 22 of the supporting structure. As shown in Figs.

1 and 6, one of the bars 53 is located midway between the frame members 46. and extends from the frame member 22 downwardly and inwardly to the upper edge of the discharge passage 15, where it is attached to the flange 51 of said discharge passage by means of bolts or rivets. On either side of the 'centermost bar 53 are locatedthe bars 54, which are somewhat shorter -'in length and terminate in contact with the outer surfaces of the frame members 46 intermediato their length, and are attached thereto by means of rivets or other suitable devices. V

The members of the lower portion ofthe recentaclc thus far described form a frame or sreleton, to which are secured the wall sections, as will now be pointedout. The wall sections comprise flat plates, pneferably of cast-iron, having a she e corresponding to the contour of the skeleton frame, and may be described as follows, it being understood that all sides oft'n'e lower portion of the. receptacle are constructed in identically the same manner. Extending horizontally between thegaentermost bar 53 and the bars 54 and frofl 'zthe lower. edge of the side walls are two rectangular plan-s58, 58, which terfi minatc adjacent to the lower extremities of the bars 54, said plates 58 abutting against the inner surfaces of the transverse web 56 of said Inn-s55) and 54', and securedthereto by means of rivets. or bolts 59, as shown in Fig. 7. Immediately below the plates 58 are triangular-1y shaped plates 60, connected to the center bar 53 in the same manner as are the plates 58 and to the. frame members -1 6, along their inclined margins, in the manner shown in Fig. 10, namely, with their margins fitting within the grooves or rabbcts -52 of said frame members 46 and in such manner that the inner surfaces of the webs of the members 46 and plate members 60 are flush. The plate members 58 and 60 are preferably connected at their adjacent margins by the provision of an offset flange 61,

formed 'along the upper margins of the plate members 60, thereby forming end grooves or shoulders adapted to receive the lower margins of the plates 58, as shown in Fig. 7. In this manner the inner surface of the wall of this portion of the receptacle is maintained smooth throughout. The Walls of the lower portion of the receptacle are completely closed by the provision of other triangular-1y shaped ,wall sections 62, 62-, located outwardly beyond the shorter bar members 54 and adjacent to the upper portion of the frame members 46, said triangular plate members 62 being attached to the short vertical bar members in the same manner as. described in connection with the plates 58, and, further, resting within the rabb'ets 52 of theframe members 46 in the same manner as described in connection with the ti'iangular plate members 60 and as illustrated in Fig. 10. Referring to Fig; (3, it will be seen how the .walls of the loweror inclined portion of the reccptacle,are united or form acontinuation of the side walls of the receptacle, namely," by extending the plates 58 and 62 a short distance above the upper margin of the horizontal frame members 22, thus permittingv the lower tier of plates 24' of the sidewall "land their corresponding. bars 23 .to overlap the upper marins of said plates 58 and .62, thereby formmg a continuous surface.

A receptacle constructed in the manner herein described comprises for the most part a comparatively large number of small sections or units, requiring little or no machine work in their production, and of such a size as to permit the same to be conveniently shipped and handled, thus enabling the manufacturer to transport a complete receptacle ata comparatively low cost. Furthermore, the parts or sections permit the 65 receptacle to be erected with little trouble and expense, inasmuch as expert 'crectors-are not required for this purpose. The advan tage of the/sectional walls is of further unportance for the reason that it permits the tacle or a substantial part thereof, it being observed that, in order to replace say one plate of the side wall, it is only necessary to remove the plates and bars immediately, above, thus permitting the desired plate to be withdrawn and a new one inserted. l ur thermorc, the sectional arrangement permits the use of cast-iron in the construction of the walls, in that plates of cast iron of a size permitting of their convenient transportation and handling may be employed, whereas a tank constructed as a'completc unit must necessarily employ sheet steel, which, as before indicated, is not a satis factory material for the construction of receptacles for the purpose herein-set forth.

Attention is called to the fact that tanks or receptacles of various shapes and sizes can be constructed in accordance with the features of the. invention, and it is 'to be understood that it is not desired to limit the invention to the particular shape of receptacle or the particular method in forming the sections or units, except in so far; as specifically pointed out in the claims.
