Description

.230. 23d, as clearly seen; in of pin 60 being threaded as channel or groove I, but located in a side oppoi site to that wherein channel 50 is located. Ab-

pose of these grooves will be described ,lateron. The closed top portion 21 of casing 20 fixedly receives one end of the elongated pin 60. which;

passes through the absorbent sections 23a, 231), Fig. 3, the other end 7 indicatedfatiilld.

In the example illustrated in the drawing; the

inner wall of closed top portion 21 of casing 20 .is provided with a recess having therein two spaced depressions Si N receive the protruding parts, 62 of absorbent sec- I tion 231;.

adapted to respectively Casing 20 is provided with a removable bottom 65 which substantially conforms in contour or. shape to that outlined in Fig. 2, casing 20 also being of such shape in section. The threaded end 3' Iifluof pin 60 is received in an opening 501) in bottom 65 and engages a nut 600 by which bottom 05 is. secured to the shell 20a of. casing 20. A c0nventional seal tight gasket 65a is provided between shell 20ia andlbottom 65,

Fixed to bottom-65 intermediate its center and W rear. end 3| as by. means of a screw. engaging Lethe; threadedopfining 51, is aisubstantially U- q shaped member 68 having the perforated upstanding ears 69. Also fixed to bottom 65, but near its rear end 3| isa spring member I0. 7 Disposed over bottom 55 is a lever 'II having up- A standing perforatediwalls 12. intermediate its ends I13, 14,. andfurther havinglahole- II' to accommodate'the member'58; the perforations inwalls J2; andthe earsbeing in registerand accom- :7 modating a transverse pin P providing a fulcrum or axis about which lever 'II'may be made to swing in a manner hereinafter described; The spring 10 always tends to .urge theyrear;end,'l4 of lever II upwards away from bottom 55,. and, consequently, the front end 13 0f lever ltdown- .wards toward bottom 65.

The'front end. I3 of lever supports-an air Y admission valve I5,.for which purpose, lever end I3 isprovidedwith a I the valve I5 projects. 1 16 having at its .upper I afla-nged member BI,

and below lever *II aconically-shaped valve memperforation through which Valve comprises, a pin and at its lower portion her I! adapted to engage the comically-shaped and perforated valve seat 18 provided in a recess n of bottom 65.? The perforationin, seat IB'registers '.With the perforation 19 in. bottom 65, wherebyto accommodate the extension 80 of valve 15,:below I valve seat 18. It is evidentthat if, a downwardly directed pressure is applied at the rear end I4 of lever II, the frontend 13. of. the lever will rise lifting valve 15 from its seat" and thereby. permitting atmospheric air to enter the casing, 20, through bottom opening I9, for mixture with fuel vapor, as explained later on.

The pin or shaft has, afireduced lower-ex-.

portion and above lever II with which slidably engages shaft 26. a. The lower end of spring 25 abuts against spacer 85, while .its upper end abuts against the shoulder 80 of circular flange 81 sorbent piece 230 which set between pieces 23b and 23d is smaller in area than either ofthese pieces producing a perimetric channel or-groove 52 communicating with grooves 50, 5|. The purformed on pin 26, said flange 8'! bearing against abutment when spring 25 is in normalexpanded condition. Shaft 20 projects-above its-flange 81 through opening 29, its

upper end 2 8 8 .being in engagement with the extension at the pivoted end of lid 40.

' Projecting through absorbent sections 231), 23c

gageable with enlargement 93 atthe end of valve stem 94 or valve 95 in head H. V

It is now evident that by raising cover'orlid 40, shaft 26 will shift downward, impellir'ig lever 14 .will move. downward and itsend 13 will move upward; ,This upward movement of lever end 73; will raise valve 15 from its seat .18 and permit atmospheric air j to enter chamber orcompartrnent 23, and also will raise shaft 90'and thereby valve 95.

Referring to thelcatalytic head or unit H disclosed in Fig. 3, the same is seen as comprising engagement with the casing 20. V d

On; the flange formed by the juncture ,of the upper and lower J portions I03, I04, there rests. a perforated plate .or screen I05, and on screen I05 is seated the catalyst '1 Which may comprise spongy platinum composition or the like. Above catalyst I 06 is. disposed another perforated plate or screen I01; Resting on the perforated bottom of holder IN is a perforated valve seat I08 cooperating ,with thevalve 94, the latter being maintained m vin h .fifi d' 1 through opening 28 ,in

Referringto the catalyst-containing head H" shown in Fig. 16-, the -metalliccup or holder I30 is so-shaped as to provideaahollow base *rIiI haveing arbottom with an opening I32 and :aflared portion I33. The lower extremity of flared portion I33 is narrower than the diameter of base I3I and is of such diameter as to accommodate the tip of a cigarette. Resting on the bottom of base I3l within the hollow thereof is a fibre or other heat insulated ring I40. Seated on ring I40 is a washer I35 made of ceraminous material. Washer I35 is cut out at its bottom to accommodate ring I40 and is also cut out at its top to accommodate a like fibre ring I 35. The opening in washer I 35 is so shaped and designed as to receive the screens I20, PM and catalyst I06 therebetween, screen I20 being seated on a. flange I31 of washer I35 and screen I2I being seated on a cut-out portion of washer I35. Above screen I2I is disposed a retainer ring I38 retaining the screen and catalyst assembly within the opening of washer I35. The retainer ring I38, which is usually of metal, is spaced from the wall of cup or holder I30 and as there are no metallic parts in contact with the latter the heat from the catalyst, when in operation, will not be transferred to holder I30.
