y and particularly that type adapted for use in connection with explosive engines.

The object of the inveritionresides in the rovision of a inulllcr which will etltectuallyv gerforin the function desired by a device of this character and which is so constructed that access to the interior thereof maybestruction and in the arrangement and conibination of parts to be hereinafter more `fully described and particularly pointed out in the appended claim.

In describing the invention in detail reference will be had `to the accompanying drawings wherein like characters of reference denote corresponding parts in the several views, in Whiche- Figure 1 is a side elevation oi the inullier showing saine connected with a controlling lever and the parts in active position. Fig. 2 an enlarged plan vieiv partly in section, Fig. 3 a section taken at right angles to that shown in Fig. 2 and with the parts of the ,I inutiler iin inactive position. Fig. l a detail perspective view of a fragment of the sleeve which rotatably surrounds the niulller casing and servesto open and close the cleaning opening thereof. Fig. 5 avdetail perspective view of a fragment of a mutller casing showin the cleaning opening.

eferring tothe drawings the device is shoyvn4 as comprising a tubular casting 0 provided'ateach end With exterior tireaus 11, whereby vsaid casing,r may be readily attached at respective ends to inlet and outlet pipes 12 and 13. The casing 1() is provided With a longitudinal slot 1.4 and on one side ot this slot'are recesses 15, 1G and 17 which torni parts ot bearings for trunnions 1819 and 20 respectively, said trunnions having secured to their inner lends respec. tively disk valves 21, and Q3. These disks 9.1, 9.2 and Q3 are provided at vdiainetrically opposite points from the truni nions 18, 19 and 20 with trunnions 24,

,and 9.6 having' a bearing' in the easing 10.

The outer end ot the truiinions 18, 19 and 20 are provided with crank arnis 27, Q8 and 29 respectively which latter are mutually connected by means of a bar 30 whereby the ro` tation of either of the truunions 18, 19 and Q0 ivill produce a corresponding rotation ot the remainder. The crank arni Qhas secured thereto one end of a link 31 while the other end of the link is connected to an operating lever 32 mounted in a suitable location. By this construction it will be apparent that through the manipulation oi the lever 32 the valves 21, 22 and 23 may be simultaneously operated from. the position coincident with the longitudinal axis of the casing 10 to a position at right angles to said axis. llach of the valves 21, Q2 and 'Z3 is vprovided with perlorations 33, the perforaltions of the valve 22 being smaller than the perforations of the valve 21 Ywhile the pertorations of the valve 23 are snialler than the peritorations of the valve 22, in other Words the ),iertorations in the valves decrease in size as the outlet end of the n'nilller is approached. Surrounding ther casing` 10 is a sleeve 35iA which is provided -with a longitudinal slot correspoinling in size to the slot 14 of a casing 10. This slot has one side provided with recesses 3G, 3T and 38 eX- tending transversely to the sleeve 34 and disposed oppositely to the recess 15, 16 and 17 respectively of the casing 1,0. These 'recesses 3G, 37 and 33 are of a sufficientsize to receive the trunnions 18, 19 and Q0 respectively and'perinit a limited rotation of Idie sleeve 3st on the casing 10 so as to bring 'the slot 35 into and out of registration with the slot 14. Vilhcn. the sleeve 34 has been rotated so as to position the trnnnions 18, 19 and 20 at the inner ends of the recesses 3G, 37 and 38 respectively, the inner walls ot' said recesses forni a portion of the bearings of said trunnions, While the inner Wall of the recesses 15, 1G and 17 constitute the remainder of said bearing. Again when the sleeve 34 is rotated so as to inove the trunnions- 18, 19 and 20 out of the recesses B6, 37 and 38 respectively the slot 35 will pass into registration with the slot 14 and permit ready removal oi the valves 2l, 22, and 23 for the purpose of cleaning. t f

It will be noted that when the valves 2l, and 23 are moved to the position shown in Fig. 3' both faces of said valve will he sul)- jeeted to the infiuence of the gas passing through the easing l0 and the force exerted hy the gas will resultI in cleaning accumulated deposits from both fat-,es of the valve as will be apparent and thus enable the eiency of the rnuiiler to he n'iaintained without frequently resortingto a manual cleaning,r of same.

What is claimed is:l

A niutller eoini'irising a. tubular casing pron vided with means aty its end for Connection with inlet and outlet pipes respectively and having a longitudinal slot in its Wall, said slot having a plurality of recesses in one side thereof, a sleeve rotatably mounted on said easing havingr a longitudinal slot therein adapted for registration with the slet in the easing, said longitudinal slotl in the sleeve having one side thereof provided with i recesses oppositely disposed to the resses in the side or' the slot in the easing respec-v tively, a plurality of perforated disk valves rotatably mounted in the easing upon oppositely disposed trunnions respectively, the end Walls of Corresponding` recesses in the sides of the slots in the sleeves and easing constituting bearings for a respective trunnion of eaeh valve, whereby the rotation of said sleeve so as to hrinthe longitudinal slot thereof in registration with the longitudinal slot of the easing will permit the removal of the dislr valves and their trunnions from the easing.

In testimony whereof affix my signa ture, in presence of tivo Witnesses.
