GEORGE EDWARD KINCI-L10F QUIRINDI, NEW SOUTH WALES, AUSTRALIA.

AUTOMATIC, srrurrnn FOR SANITARY CLOSET-SEATS.

Specification of Letters Patent Patented May 13, 1919.

Application filed. October 14,1915. Serial No. 55,850. y

To all whom it may concern:

Be it known that I, GEORGE EDWARD KINoH, subject of the King of Great Britain and Ireland, residing at The Poplars, Quirindi, New South Wales, Australia, have invented new and useful Improvements in Automatic Shutters for Sanitary Closet- Seats, of which the following is a specification. v y

This invention relates to, sanitary closets and consists in certain improvements in seat preventing access of flies into it. The slides in which the shutters work are mounted on a pair of flat frame bars which are each fixed to the underside of the seat by two screws, one of which is set in a forked end or slotted hole in the bar in order to allow for shrink-age movement of the wood of which the seat is constructed.

The operating mechanism comprises a canting sill bar carried on pivotal rocking brackets which permit vertical movement of the sill barinrelation to the rear portion of the seat, this sill bar is normally held upward by springs,and is pressed downward by the weight of a person resting on it when the seat is in use. Thegvertical movements of the sill bar are transmitted through said on line a-a and b'b Fig. 1, omitting certain parts; Fig. 4 fragment transverse section illustrating the lap joint of the slide shutters at the meeting edges thereof; and

Fig. 5 fragmental detail plan illustrating the mounting of the frame bars which carry the slides in whichthe shutters move.

A is the seat panel, B the aperture therein, C and D slide shutters, Z Z slides of folded sheet metal secured in any suitable manner to the undersides of the. frame bars F F, E upwardly flanged rear edges of shutters C i and D, F F frame bars, f screws holding same to underside of seat A, f forked (or slotted) ends of frame bars which permit relative movement of the seat A and parts carried thereon so as to make the adjust- ,ment of said parts independent of shrinkage of the seat A, G G lapping-flanges at meeting edges of shutters G and D, H H levers connected respectively with the shutters C and D by cap studs J and J which are fixed in the shutters and move in are slots K and K in the levers H H. The

levers H H are fulcrumed on pins L L fixed in blocks set below the seat panel, and

they are operated by pins M M which work in eyes in the ends of the push bars N N which are connected at their forward ends to the rocking brackets P P The sill bar Q ismounted on the rocking brackets P P which are vertically movable on the fixed studs R R, and are pivotally attached at S S to the forward ends of the push rods T T are helical springs in compression, threaded over the rods N N to which they are secured at U U, their rear ends taking abutment against the guides V V, which are sufliciently free to allow a little lateral movement of the push rods N N, which have not an exact rectilinear motion at the rear ends owing to the curved are lugs screwed to the underside of the seat and pressingupon the slides Z Z to support them.

The shutters are normally closed as shown in Fig. 1, a fly proof joint being made by the flanges G G and the guidesZ Z. When the weight of a person is imposed on the sill bar Q, said bar is depressed level with the seat board A, as shown bythedotted line, with the result that the push rods N N are forced backward against the pressure of the springs T T. This backward movement of the barsN N is applied to the" slotted levers H H through the pins M M, and these levers acting on the shutters G and D through the cap studs J and J force the two leaves of the shutters apart, moving them laterally, till clear of the seat aperture. When the pressure of the sill path in which the pins M M move. W W

bar Q is relieved, the parts are restored to normal position by means of the springs T T withthe .resultthat the pan is immediately covered from view by the shutters and sealed against entry of-flies through the seat aperture.

The rising sill bar device may be used with slide shutters and intermediate operating gear constructed or arranged otherwise vtliarras shown in the drawings.

l npractiee, the seat, with the fittings deseribed, is made as a unit ,Which can be -fiXed read ly over afiushing-basin or upon a casing or frameinclosing an earth-pan.

-What I claim as my invention and desire to secure-by Letters Patent is 1. ,A closet seat comprising a seat panel having an aperture therein, .a pairof shutters moyable toward and away from each other to cover and uncover said aperture, 1 guides in which said shutters are slidably supported, a pair of levers fulcrumed on said panel at the rear thereof and connected to said shutters, apair of substantially parallel rods connected to aid levers and .eX- tending forwardly therefrom, and means at the front of saidpanel connecting said rods and movable to operate the rods to swing the levers and open the shutters.

2. A closet seatco nprising a seat panel having anaperture therein, a pair of shutvters moyable towardandfaway from each other to cover and uncover said aperture, guides in which said shutters are slidably supported, a sill adjacent the front edge of .said panel, brackets pivoted on said panel having arrns carrying said sill and other arms, and levers pivoted on said panel .and

connected to said shutters, and rods connecting said levers/t0 the last mentioned I arms of the. sill brackets.

3. Ina closetseat, aseat panel, a canting sill adj acentthe front edge thereof, shutters slidingly mounted upon the underside of said panel, longitudinally movable rods operatively connected to said sill and to said shutters to open said shutters upon said .sill

being depressed by the. weightof a person upon the seat, and means to actuate said rodstoclose said shuttersand raise said sill when the latter is relieved of the persons Weight.

ft. :Ina closet seat, a seat panel, a canting s ll ad acent the front edge thereof, shutters slidingly mounted upon the underside of said panel, levers pivotally connected to said ing sillsupportedon pivotal brackets, push rods with retiring springs articulating said brackets to said levers, pins on said shutters working in the slots in said levers, and channel guides for said shutters.

6. The combination of a closet seat panel having, an aperture therein shutters movable toward or away from each other to cover or uncover said aperture, supports in which sa d shutters are slldably mounted, levers fulcrumed on said panel at the rear end thereof and connected to said shutters, substantially parallel rods connected to said levers and extending forwardly therefrom, guide means for each of said rods on said anel SJIiH means attached to each rod and to said guide means, and pivotally mounted means at the front. of the seat panel connected to said rods to actuate the same.

7. A closet seat comprising a seat panel having an aperture therein, shutters movable toward or away from each other to cover or uncover said aperture, supports in which said shutters are slidably mounted, a sill adjacentthe front edge of said panel, levers fulcrumed on said panel at the rear end thereof and connected to said shutters, substantially parallel rods connected to said levers and extending forwardly therefrom, bell-crank connections between said rods and said Slll, guide means for each of said rods on saidpanel, and spring means attached to each rod andlto said guide means, said latter meansoperating to close said shutters and raise said sill when same is relieved of a persons weight.

In testimony whereof I have signed my name tot-his specificationin the presence of two subscribing witnesses.
