ASH REMOVER` Filed NOV. 10, 1936 Patented' Nov. 3o, 1937 ASH REMOVED Charles ll'. Bove, Canton, Ohio, assigner of twenty-two and one-hall.l per cent to Eimer George Baird, Canton, and twenty-two and one-half per cent to Charles W. Traynor, Massillon, hio
Application November 1o, 193s, salama-11am s claim.v (ci. 11o-lcs) The invention relates to apparatus for removing ashes from beneath the grates of furnaces and the like.
The object of the invention is to provide means for removing the ashes from the usual ash pit located beneath the grate of a furnace.
A further object is to provide an ash remover in which an auxiliary or sub-ash pit is located below the ordinary ash pit of the furnace and 0 communicates with the underside thereof, an inclined screw conveyer being extended into this auxiliary ash pit for removing the ashes, the auxiliary ash pit being tapered toward the screw conveyer so as to convey all of the ashes from 5 the furnace.
A further object is to provide a crusher within the auxiliary ash pit to crush any' clinkers or the like to such size that they may be conveyed out by means of the screw conveyer. Another object 0 is to provide a concave thread upon the conveyer screw for more readily conveying the ashes.
A still further object is to provide a ring for connecting the auxiliary or sub-ash pit to the ordinary ash pit of the furnace whereby the 5 auxiliary ash pit may be easily connected to furnaces of various diameters.
The above objects together with others which will be apparent from the drawing and following description, or which may be later referred l to, may be attained by constructing the improved ash remover in the manner illustrated in the accompanying drawing, in which Figure 1 is a vertical longitudinal section through an ash remover embodying the inven- 5 tion;
Fig. 2, a plan sectional view of the ash remover taken substantially on the line 2-2 Fig. 1; and
Fig. 3, a detail sectional view of a portion of the improved conveyer screw.
40 Similar numerals refer to similar parts throughout the drawing.
A portion of the fire pot of an ordinary furnace is indicated generally 'at I0 and the grate bars are shown at II mounted above the usual 45 ash pit I2 formed within the walls I3, all as in usual and ordinary practice.
Located below the hoor level and directly beneath the ash pit I2 is an auxiliary or sub-ash pit I4, the walls I5 of which converge toward 50 the opening I6 so that all of the ashes will be directed toward said opening.
Communicating at its lower end with the opening I6 of the auxiliary ash pit is an upwardly inclined feed tube I1 extending above the door 56 level and having at its upper end a downwardly inclined discharge spout IB through which the ashes are discharged into the ash can I9, the discharge spout tting into a suitable opening in the lid 2li of the can so as to prevent liberan tion of lighter particles of the ashes. 5
A conveyer screw 2| is mounted within the feed tube I1, the upper and lower ends thereof being preferably journaled in roller bearings' as indicated at 22 and 23 respectively. The lower portion of the conveyer screw is located immediately below the opening I6 of the auxiliary ash pit so that the falling ashes come intocontact with said screw.
'I'he screw 2| may be rotated by means of a hand crank 24 or if desired, it maybe mechani# `l5 cally driven as by the motor 25 mounted in any suitable position as upon the upper end portion of the feed tube I1. A pulley 26 may be ilxed upon the shaft of the motor 25 and connected as by the belt 21 to a pulley 23 fixed upon the upper '20 end of the conveyer screw shaft.
The conveyer screw 2| is preferably provided with a concave thread as clearly shown at 29 in Fig. 3, so as to facilitate the conveying of the ashes upward through the feed tube I1. g5
For the purpose of connecting the shell forming the auxiliary-ash pit I4 to the shell of the 'ordi :ary ash pit I2, a ring 30 is provided, this ring being connected to the annular flange 3| of the ordinary ash pit as by the bolts 32 and hav- 30 ing slots 33 therein adapted to be connected to the annular flange 34 of the auxiliary ash pit as by bolts 35. Th slots 33 permit adjustment of the auxiliary ash pit and feed tube I1 to any desired angle relative to the furnace. 35
, It will be seen that with this construction the same size auxiliary ash pit may be connected to the ordinary ash pits of furnaces of various diameters by using a ring 3l) of the necessary size.
For the purpose of crushing any clinkers, among the ashes, which might be of suflicient size to obstruct or clog the conveyer screw, a crushing device is provided within the auxiliary ash pit comprising a grid or grating 36 having a plurality of spaced bars 31, preferably tapered toward their upper edges, as shown in Fig. 1.
The cooperating portion of the crushing device includes a jaw or gate 38 hinged at one end to the wallvof the auxiliary ash pit as at 39, and provided with teeth 40 adapted to cooperatevwith 50 the bars 31 to crush and break up any clinkers which may be contained in the ashes.
This gate or jaw is adapted to be operated by the rod 4I having at its lower end a fork 42 connected as by the pin 43 to the slotted ear 44 55 upon the jaw or gate 38. 'I'he other end of the rod is provided with a fork 45 having a pin 46 located through the slot 47 in the operating lever 48 which is pivoted as at 49 upon a sector 50 mounted in any suitable manner as upon the feed tube l1. A pawl 5| operated as by a hand grip lever 52 upon the handle portion of the lever 4B, is adapted to engage the teeth of the sector 50 to hold the lever in any desired position.
It should be understood that the jaw or gate 38 serves not only to break up clinkers but also controls the draft to the grates Il and regulates the feed of ashes to the screw conveyer. A tubular guide 53 may be provided forthe control rod 4|, this guide having a flange 54 at its lower end by means of which it may be connected to the wall of the ash pit, the rod being mounted for reeiprocation within said tubular guide. A cap 55 may be threaded or otherwise connected upon the upper end of the tubular guide and provided with a drilled aperture 56 through which the rod has a snug sliding t.
I claim:
