The activating arm 60 has a portion thereof received within the linkage cover 34 and has laterally extending

projections

63 and 64 each adapted to engage one of the side walls of the linkage cover 34 to limit outwardly movement of the activating arm 60. The

projections

63 and 64 and the guide member 61 cooperate to restrict longitudinal movement of the arm 60 laterally of the linkage cover 34 and the guide slots in the

side walls

36 and 37 of the linkage cover 34 restrict lateral movement of the activating arm 60.The portion of the activating arm 60 positioned within the linkage cover 34 has an upwardly extending rib 65, for a purpose later described.

The linkage to move the contact member 59 includes a contact support member 66 having the contact member 59 suitably mounted thereon. The contact support member 66 extends vertically through the slot in the top wall 46 defining the switch chamber and is positioned adjacent the partition 50 of the handle 42 and the contact member 59 extends through the slot in the partition 50 and is received in the passage in the guide member or block.

The linkage to move the contact member includes means supported on the actuating arm 60 and attached to the contact support member 66 for moving the contact member 59 to complete the electrical circuit in response to weight being applied to the toilet seat 7, such as a person sitting on the toilet seat 7. In the illustrated embodiment, an upright member 67 is positioned in parallel spaced relation with the contact support member 66 and has suitable means securing the upright member 67 to the contact support member 66, such as a set screw 68 extending through the upright member 67 and into engagement with the contact support member 66 for moving same into clamped engagement with a body member 69 of a clamping device thereby effecting connection between the contact support member 66 and the upright member 67.

The upright member 67 has a slot or aperture in an upper end thereof adapted to receive a generally horizontal linkage member 70 whereby the upright member 67, the contact support member 66, and the contact member 59 are supported on the horizontal linkage member 70 which is supported on the activating arm 60. In the illustrated embodiment, the horizontal linkage member 70 has an upwardly extending notch 71 in a lower edge thereof adapted to receive the upwardly extending rib 65 of the activating member 60 therein. The generally horizontal linkage member 70 is illustrated as a planar member having a shoulder 72 adjacent an outer end thereof and adapted to be engaged by the upright member 67 to substantially limit move ment of the upright member 67 along the horizontal member 70. The horizontal linkage member 70 has an end portion thereof extending through the guide slot in the end wall 41 of the extension of the linkage cover 34, thereby limiting lateral movement of the switch linkage.

The air deodorizer structure 1 is particularly adapted for use with a toilet stool 2 having an upper edge thereof defining the toilet bowl rim 8. The toilet stool 2 has a hinge member 73 for hingedly mounting the toilet seat 7 on the toilet stool 2. The toilet seat 7 is spaced from the toilet bowl rim 8 a selected distance to permit the activating arm 60 and the outstanding portion 28 of the nozzle member 26 to be positioned between the toilet seat 7 and the toilet bowl rim 8. In the illustrated embodiment, spacers 74 are positioned between the hinge member 73 and the toilet bowl rim 8 to effect the selected spacing therebetween.

Suitable means are mounted on the toilet seat 7 and engageable with the toilet bowl rim 8 for resiliently maintaining a selected spacing therebetween until weight is applied to the toilet seat 7, such as a person sits on the toilet seat 7, thereby moving same and the activating arm 60 toward the toilet bowl rim 8. In the illustrated embodiment, spacer members 75 are suitably secured to the toilet seat 7 and each spacer member 75 has a resiliently supported projection 76 extending therefrom and engageable with the toilet bowl rim 8.

When a person sits on the toilet seat 7, the weight of the person compresses the spring 62 supporting the ac tivating arm 60 and the resilient members supporting the projections 76 thereby allowing the activating arm 60 to move toward the nozzle member 26 which in turn allows the contact member 59 to move by gravity into engagement with the

electrical terminals

57 and 58 thereby energizing the motor 54 and operating the fan 4. The air moving blades 53 of the fan 4 effect inwardly directed flow of air and odors through the inlet 6 in the outstanding portion 28 of the nozzle member 26 and through the aperture or passage 18 in the partition 17 and then through the air deodorizing filter 3 and away from the toilet stool 2 and the air deodorizer structure 1. Upon release of weight from the seat 7, the spring 62 and the resilient members supporting the projections 76 raise the seat 7 and the contact member 59 to turn off the fan 4.

The nozzle member 26 may be reversed to permit the air moving and deodorizer structure 1 to be positioned on the opposite side of the toilet stool 2. The linkage cover 34 is removably mounted on the nozzle member 26 and must then be reversed on the nozzle member 26 to maintain the end wall 41 in position above the handle 42 to thereby serve as a guide for the movement of the horizontal linkage member 70 during movement of the contact member 59 into and out of engagement with the

electrical terminals

57 and 58.
