Referring to Figs. 1, and 2, the toilet fixture 1, in-toilet room 2, o-f'passenger coach 3, is arranged to be flushed by'depression of handle '41 forming part of lever. 5, pivoted on pin 6,, and the extension 7 of which is arranged to control the discharge of sewage from toilet 1, as Well as control the supply of water thereto, for the flushing thereof. Controlling" extension 7 of lever 5 is'control unit 8, more fully hereinafterdescribed, arranged to be actuated by a partial vacuumproduced in pipe or conduit 9 by venturi 10 secured exteriorly 'to the roof 11 o-f coach 1 when said coach is traveling in excess of a predetermined mini mum speed ineither direction.

Referringto Figs. 3 and 4, showing a modified form of control for lever-"5, of toilet 1, control unit 15,'m"or'e fullyhereinafter described, is arranged to prevent flushing of toilet 1, by lever 5 by the following apparatus. Cam bar lfi comprises one portion passingthrough-control unit 15 for effecting I operation thereof and another portion pivot ally connected-to the free end of crank 17 secured to rod 18, operating in bearings .19 and 20, and supporting vane 21 the plan of which is normally restrained to assume a transverse position with relation to the longitudi I tached to the body of coach 3.

23,0ne end of which is secured to the freeend ,of said crank and the other end suitably atv liei'erringte i we staring still another modified form of control for lever 5, of toilet 1, control unit 25, more fully hereinafter described, is arranged to prevent operation of lever 5 to flush toilet 1, by the following apparatus; generator 26 driven in known manner by car axle 34, normally supplies energy for lighting coach 3, and operating auxiliary apparatus therein, through conductors 27, 28 and 29, said generator being effective to supply said energy only when said coach is travelling in excess of a predetermined minimum speed, the control of said generator to supply said energy being elfected by switch board, or control'panel 30, it being understood that when coach 3 is traveling in excess of a predetermined minimum speed the generator 26 is rendered effective to energize control unit 25, through conductors 31 and 32 and when said coach is traveling at less than said minimum speed said generator is ineffective to supply said energy to both of said control units, said locking unit comprises housing 41, having slots 4242 arranged to receive extension 7 of lever 5,

also bosses 43-43 supporting shaft 44 pivotedon which is hell crank 45 to the bifurcated extension 46 of which is pivotally secured by pin 47, the rod 48, operating in boss 49, of control unit 8 only, the rod 50 operating in a similar boss in the control unit 25 only.

Bell crank 45 also has locking extension 51, having locking head 52 arranged to be moved over extension 7 of lever 5 whereby said lever 7 cannot be operated to flush the toilet.

toilet 1 tobe flushed.

Also formed on bell crank 45 is lug 53 extending into recess 54'of key hole boss 55 having key hole 56, and through which key 57 may be inserted, and when turned, will depress lug 53 thereby moving locking head 52 away from extension 7 of lever 5, whereby said lever may be operated to flush toilet 1.

vacuum therein generated by Venturi unit 10 will be communicated to cylinder 62 thereby raising piston 61 and rod 48 whereby bell crank 45 is rotated counter-clockwise to remove locking head 52 from the path of exteir sion 7 of lever 5, in this manner permitting A suitable vent 65 supplies air to the under side of piston 61 to compensate for leakage of air therepast and displacement due to the rise of said piston.

Referring to Fig. 8, showing control unit 25, to the upper end of shaft 50, is secured magnet core operating in magnet 71 secured in combined magnet housing and magnetic yoke 72 secured to housing 41 of unit 40. When magnet 71 is energized, as will be more fully hereinafter described, magnet core 70 and likewise rod 50 is moved upwardly thereby simultaneously rotating bell crank counter-clockwise to permit operation of lever 5.

Referring to Fig. 9,-showing control unit 15, the modified locking housing 7 5 is formed with bosses 76-76 having rectangular orifices 7 77 7 through which cam bar 16, (Figs. 3 and 4) is arranged to reciprocate, saidbar having a lower cam face 78, inclined cam faces 7 979 and elevated cam faces 8080.

When a car as 3, is at rest, and vane 21, (Figs. 3 and 4) is transversely positioned as shown, bar 16 is positioned as shown by Fig. 9, the bifurcated extension 47 of bell crank 45 resting on recessed cam face 78, in this manner restraining locking head 52 (not shown) to lie in the path of extension 7 of lever 5 whereby toilet 1 cannot be flushed thereby.

When said car 3 has accelerated to a predetermined speed vane 21, acted upon by the air current passingover the roof of said car, will be deflected thereby causing rotation of rod 18 and longitudinal movement of bar 16, said longitudinal movement depending upon which direction said caris traveling, in either event the inclined cam face 79 will elevate extension 47 of bell crank 45 and locking head 52 will be removed from the path of extension. 7 whereby lever 5 may be operated to flush toilet 1;

Housings 41 and 75 are formed with suitable lugs, as 85, for suitably securing control units, as 8, 15 and 25, to the body of coach 3.

, Referring to Fig. 10, showing a modified form of control for toilet fixture 1, the valve 86 is arranged in the water supply line for flushing toilet 1, and is normally closed. Lever 87, pivoted on pin 88, has one extension 89 arranged to depress valve stem 90 and open said valve, and another extension 91 pivoted to rod 92 which may form an extension of rods 48 or 50 in this manner eliminatingthe use of unit 40 where flow of water is required for sewage evacuation, as operation of lever 5 1f actuated, cannot supply water to flush toilet 1 unless valve 86 is open.

96, having discharge'end 97, pivoted to which is lever 98, pivoted on pin 99, arranged to raise said elbow 96, by means of rod 92, to the of is lowered for'discharge thereof. As d'e-- scribed in connection with Fig. 10, rod 92 may be an extension of rods 48 or 50 whereby the discharge end 97 of elbow 96 will only normally discharge when car 3 is traveling in excess of a predetermined minimum'spe'ed.

lVhereas car 3 has been shown as a railway coach, or pullnian sl s It may be some other form of conveyance arranged to travel on paved roadways.

'From the foregoing desfcrlption it will be apparent that applicant has disclosed appa ratus for preventing the discharge ofsewage or other waste matter from toilet fixtures supported by moving. conveyances unless said conveyance is traveling in excess of a prescribed minimum rate of travel and whereas the novel form of control has been shown as applied to a toilet fixture, or bowl, it maybe equally well adapted to wash basin fixtures or urinals.
