vision of an attachment of this character,

wherein the construction thereof is such as to be automatically operated so as to render the bowl odorless and also to maintain it clean,

I thereby assuring sanitation to a lavatory or the like.

A further object of the invention is the provision of an attachment of this character which is extremely simple in construction,

thoroughly reliable and eflicient in its operation, automatic in its action, strong, durable,

and inexpensive to manufacture and install. With these and other ob ects 1n view, the invention consists in the features of construc- I tion, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawings, which disclose the preferred embodiment of the invention, and pointed out in the I claims hereunto appended.

In the accompanying drawings Figure l is a side elevation of a lavatory bowl and adjunct parts thereof, showing the ventilating attachment constructed in accord- I I ance with the invention applied thereto, por- 35 tions of the same being in section.

Figure 2 is a fragmentary top plan View.

Figure 3 is a fragmentary vertical transverse sectional view.

Figure 4 is an enlarged fragmentary vertical longitudinal sectional view.

Figure 5 is a sectional view on the line 55 of Figure 1 looking in the direction of the arrows.

Figure 6 is a fragmentary elevation partly 5 in section looking toward the rear portion of the bowl. I

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, A designates generally a lavatory or closet bowl of any standard constructi-om-B the swinging SGa-tthGIBOf, C thecover and D the flushing tank for said bowl. The seat B carries yieldab'le hangers 10 connected with the pivot pin- L tle 11 for the cover-C so that said seat B can be swung from horizontal to vertical position or vice versa and is normally lifted when in a horizontal position" from the top edge ofithe bowlA'under the action of springs 12 inth'e hangers 10 for a purpose presently described. L The flushing tank D has the water inlet pipe connection 13 with the bowl the latter being formed with 1 a spout 14: internally thereof with a depending lip "15 to direct the water from the pipe 13 andspout l downward'ly in 5 theabowl A, the latter being flushed in conformity with standard types of'bowls. Im-' mediately beneaththe spout 14: and formed in the bowl is a ventilating trap 16,the'wa ll 7 17 thereof confronting thepathof' -the water from the spent 14 'being'perforated at'18 :a'nd

overhanging this perforated wall "17 is a guard or baffle 19 as clearly shown in Figure t of the drawings, the trap 16 being in communication with a vent pipe 20 which extends verticallyitowithout the inclosure constituting the lavatory so that odors can pass'from the bowl A through the trap 16 and bejdis- I charged through the vent pipe 20 to the .atmosphere'in a manner presently described. At a suitable location away from the bowl A preferably beneath the floor of the lavatory or within a cellar of a house or other-inclosure isian electric motor 21 connected with the 5 currentfeed wires 22'for'ming a circuit there'-'' to and this circuit includes a normally open switch23, the blade Qtof which through the extension 25 is connected with the piston 26 within a cylinder 27 of-an air-operated check device, the latter being connected with a weight rod 28 carrying a weight 29 at its free end. This rod 28 is engaged witha lifter lever 30 fulcrumedupon the pivot pintle l1 and is formed with a rocker extension 31, the latter being disposed beneath and againstthe under face of the seat B so that when the latter is occupiedthe lever 30'wi1l be moved upwardly, thereby pullingupon the r'od28 I against theresi'stance of the weight 29 and 1'00 the connection of this rod 28 with the extension causes the automatic closing of the blade 24 of the switch 23 and thereby closing the circuit to the motor 21 for its operation. When the seat B becomes unoccupied the latter raises a limited degree and the checking deviceincluding the cylinder 27 and the piston 26 retards the opening movement of the blade 24 of the switch 23 allowing said switch to open slowly fora purpose presently defan 33 will be driven so as to draw through the trap 16 on the bowlA all odors and deliver the-same to the pipe 20 whence they will be discharged to the atmosphere thereby rendering the bowl'A thoroughly sanitary and odorless. I r

. Extending from the water supply pipe 36 to the flushing tankD isa branch spray pipe 37 which opens into-the pipe close to the trap 16 and this branch spray pipe 37 is provided with a hand operated cut-oil valve 38 so that on the opening of the valve water can be delivered to the pipe 35 and be con-' veyed into the trap 16 for the cleaning of the same and also its perforated wall 18 thereby preventingany possibility of choking or clogging of the trap. The trap 16 is above the water line in the bowl A so that it will freely circulate within the said bowl when the fan 33 is operating. l

? It will be observed that when the seat B is depressed the lever 30' is moved upwardly thereby pulling upon the rod 35 against the weight 29 thus. closing the; blade 24 of the 1 switch 23 and starting the motor 21 as the cirou it'thereto is closed and simultaneously the fan 33 is driven for extracting odors from within the bowl. On unoccupancy of the seat B the check device including the cylinder 27 andpiston 26 will cause the slow opening of the switch 23 to stop the motor 21 after a determined time of unoccupancy of the seat for thorough ventilation of the bowl as will be clearly obvious.

1' What is claimed is v1. The-combination with a closet bowl having a'vent and water supply chambers, of a motor on the closing of its circuit by the switch.

2. The combination with a closet bowl having a vent and water supply chambers, of a 1 movable seat for said bowl,-a lead from said vent, a fluid control check, lever connections between the check and seat, a motor circuit control switch associated with the connections, a fan within the lead and operated by the motor on the closing of its circuit by the switch, and a resistance weight carried by 'theconnectionsbetween the check and seat.

In testimony whereof I affix mysignature.

LOUIS HANSON.
