"This invention relates particularly to v valves' ofthe type in which the sealing element is a disc cooperating with a sealing face surrounding the valve port and arranged 1n t the valve opening movement to slide in'con- V tact with a lateral continuation or extension of the sealing face. 7 V,

Special objectsof the 'invention are to pref ,ventthe accumulation of sediment or solid matter from intefering with-the proper opening,vclosing and sealing of the valve and to 1 provide a simple, practical form of valve structure, adaptable for continuous, effective use in the handling of-fiuids or less solid matter.

' 'The foregoing and otheridesirable' objects 7 are attained by-a novel form of valvestructure,including in particular, a novelar'range f path gwithout binding such solid matter against an abutment such as might restrict the "2a opening for closing action of the valve.

Various "other novel "and important features of the invention will'appear in, the

course of the following specification. n

The base 7 of the valve is constructed according to the particular needs or uses to which the valve is put. In the case of the :5 construction first shown, this base is made with'a flange 8 by which the same may be bolted to the tank 9 and in the construction shown in Figures 3, 4 and 5,1't is made with a threaded neck 10 by which it may be so screwed onto the lower end of the pipe 11 forming the dust pocket in the gas flue 12.

The base has a valve port 13 surrounded by a fiat sealing face 141 and a valve pad 15 forming a smooth continuation to one side of said sealing'face. Cooperating with the sealing face and with the lateral extension of the same is a valve disc 16 arranged to beslid over said faces by a lever 17-keyed at 18 to' the actuating post 19 and having a sliding hearing at 20 with the inner face of a supporting or backing plate 21. A special feature of the invention isthat the backing plate is supported in parallel spaced relation to the base by means providing a clear and practically unobstructed way 3 between and about said members so as to leave the moving elements of the valve oper- 'ating in unconfined relation. The means for thispurpose consists in the present disclosure as of a series of studs or screw bolts 22' and nuts 23'fastening the supporting plateto the base v against interposed spacing columns 24; In the case of the tank valve only three such fastenings a're shown and for the dust valve (55, I (Figure 5), four such fastenlngs are illustrated, and sald fastenings are arranged in both instances to leave a clear way in the line of travel ofthe valve so that solid objects deposited in the line of travel of the valve will be pushed out of the way by the valve disc withoutencountering any obstruction.

The coupling between the valve disc and actuating lever is shown as provided by a independent rotative movement of the valve 1 mlght result from sedimentation or 1ncrustadisc. The lever is loosely keyed on the actuating shaft, as shown, so that it may adjust itself to slide freely over the back plate. A suitable lever or handle mechanisinrmay be provided for turning the shaft or valve stem 19, such as indicated at 28. g

If desired, the working parts of the valve may be protected against heavier solids or against mechanical injury by surrounding the same more or less witha guard or screen such as shown at 29 in Figure 1, said screen being indicated as a cupped screen or guard element inverted over the valve structure and secured to the back plate bythe bolt at 30.

In both constructions illustrated, the moving parts of the valve are unconfined about the sides and in the general plane of operation, leaving the valve element and lever free to push before them, such sollds as tion. The valve therefore is enabled to clear itself and to maintain itselfin proper work ing condition irrespective of the solids carried by the fiuid.,- In the dust valve construction shown in Figures 3 to 5, the valve partsv operate in open air and'so are more accessible than in the case of the tank valve first shown, but in both casesthe main parts of the valve are accessible at the sides of the valve structure and so can be examinedor relatively adjusted, as'to free them from a binding condition, etc., Without taking the valve apart.

The open spaceabout the periphery of the valve body gives exceptional access of fluid to the valve element, making itfunnecessary' ordinarily-to provide any port in the backing plate. This isthe condition illustrated in Figure 1. If desired,however, the backing plate may be ported in line-with the port in the base member, asshown at 31 Figure 4.; The strength of the spring 27 between the valve element and its actuating lever is suf-' ficient to hold these parts in proper sliding engagement in the guideway between the parallel supporting surfaces in the valve bodyandits force always will be governed according as to whetherthe pressure of the fluid is acting to seat the valve as it isin Figure 1, or the valve disc is actingagkainst v the pressure of the flu d as it s in Figure 3,v
