This invention relates to sanitation devices and has particular reference to sanitation devices for automatically sterilizing or giving a freshening treatment to articles which are used successively by different persons so that each person may have the use of the article in an absolutely sanitary condition. Among such articles are toilet seats, dental and barber shop supplies and the like which are used successively on or by different persons.

It is the principal object of the present invention to provide an improved device of this character of simplified construction and arrangement. In accordance with this object the invention comprisesa device in which two of the articles are included oneot which may be in use while the other is being sterilized or freshened or has been sterilized or freshened. The device includes a sterilizing or refreshing chamber having a closure which serves to seal the chamber and which has disposed onopposite sides thereof the articles to be sterilized or freshened the closure being adapted to be rotated through 180 to bring one of the articlesinto position for use and the other into position within the sterilizing or refreshing chamber. The sterilizing or freshem'ng means may consist of an electric heater or lamp or chemical or other disiniectingdrying or freshening media. A locking handle for the closure is suitably operatively connected with the articles to be sterilized or ireshened so as to ensure that the articles will be :in a position to permit rotation of the closure when the handle is operated to open the closure and that the articles are free for service when the handle is in looking position.

In. the applicationof the inventionto a toilet the apparatus includes a sterilizing or refreshing chamber located behind and above the bowl of the toilet and a closure for the sterilizingor re- Ireshing chamber on which are hingedly mounted a pair of toiletseats one associated with each of two faces of the closure. The closure or a portion thereof is adapted to be rotated about a central axis in order to bring the one seat which has been in thesterilizing or refreshing chamber into position behind the toilet bowl and the other into the sterilizing or refreshing chamber to be sterilized or freshened. A handle for operating the closure is operatively connected with the seats bycable or thelike in such manner as to cause a lowered seat to rise when the closure is being unlocked. Wherethe seat is formed of two half seats the central part of the closure may be in the form of a fixed panel around which a frameworltcarryingthe halfseats rotate. 'I'hisarrangement permits the convenient disposal of the sterilizing or refreshing unit in the sterilizing. or refreshing chamber immediately behind the stationary panel and between the two halves of a seat.

For a better understanding of the invention reference is made to the accompanying drawings in which are illustrated three embodiments of the invention as applied to the sanitation of toilet seats. A device such as illustrated may be used on the toilets of clubs, railway stations, public buildings or the like where the toilets are used by a great number of different persons. For public purposes the device may be made initially operative by a switch controlled by opening or closing the door of the compartment containing the toilet or by a coin controlled device or otherwise.

Fig. 12 is a section on the line l2r-l2x of Fig. 11 andFig. 13 a section on the line l3a:-l3x of Fig. 11. Fig. 14is a front elevation corresponding to Fig. 1 of a second embodiment and Fig. 15 a horizontal section on the line l5:c!5m of Fig. '14, while Fig. 16 is a front elevation of a still further embodiment and Fig. 17 a horizontal section on the line Throughout the several figures of the drawings like references indicate like parts.

Referring to Figs. 1 to 13 of the drawings l indicates the bowl of the toilet, 2 the sterilizing or refreshing chamber suitably of vitreous earthenware of the sanitation unit disposed above and engages the compression springs behind the bowl and 3 the closure or front wall of the sterilizing or refreshing chamber. The closure is formed of a tubular frame 4 with filler panels 5 and 6 of laminated plastic or other material at each side of a centrally disposed stationary panel I and is rotatable about upper and lower pivots 8 and 9 secured in upper and lower members Ill and Illa respectively of the sterilizing or refreshing chamber. In order to prevent rotation of the central panel 1 the upper part of the upper pivot 3 is of non-circular shape and this part of the pivot extends through an opening of similar shape in a locking plate 8a attached to the upper member ll of the chamber. The panel I is supported in brackets I4 rigidly secured to pivots 8 and 9. The sterilizing medium in the form illustrated in Figs. 1 to 13 consists of an electrical heating unit l2 projecting into the sterilizing chamber and supported in a block l3 of heat and electrical insulating material secured to brackets 14 mounted on the pivots. The heating unit I2 is supplied with current through an insulated cable secured by bracket 13a to the upper member ll] of the sterilizing chamber. Associated with each face of the closure of the sterilizing chamber is a toilet seat. Each toilet seat is arranged as two half seats l5, carried by brackets l6 mounted on horizontal rod I! supported in the lower member I I of the closure and is adapted to be lowered into position on the toilet bowl against the action of torsion spring l8 and compression spring 18a, two only of which are indicated in Fig. 11.

With each pair of springs IBa is associated a brake clip I9 embracing the horizontal rods 11. The clip is formed with notches ISa which engage and brake pins [1a during the rotation of the horizontal hinge rod IT. The rear of the clip lBa. It is adapted to be moved to compress the springs and release the rods by means of a cable 20 extending through one of the tubular uprights of the frame 4 and secured to a locking handle 2| for locking 'the closure in position in front of the sterilizing chamber. A compression spring 20a on the cable prevents backlash of the handle 2|. The handle 2| which is formed with handle arms on each side of the closure is pivotally mounted on the tubular frame and is formed with a projecting nose 22 adapted to engage a recess in one of the two plates 23 secured to the lower face of the upper member I 0 of the sterilizing chamber.

Initial downward movement of the handle arms serves to pull the cable 20 and compress the spring 18a thereby freeing pins I la from brake clip I9 and permitting the used toilet seat to rise to a vertical position by means of torsion spring l8 while further movement brings the nose 22 out of engagement with the recess in the plate 23 freeing the closure which can now be rotated through 180 to bring the seat previously within rotate with rod 11, moving in and out of notches l9a, the sides of which diverge to permit such movement of the pins. The lowering of the seat also stresses torsion spring 18.

In the lowered position of the toilet seat pin Ila re-engages with the clip I 9 and holds the seat in this position against the lifting action of the torsion spring l8. During the lowering of the seat the compression spring 20a serves to keep the cable 20 taut and the handle 2| in position. The direction of rotation of the closure will alternate.

In the embodiment illustrated in Figs. 14 and 15 which in other respects is similar to that shown in Figs. 1 to 13, the closure 3 is rotatable as a whole about upper and lower pivots and the sterilizing or freshening unit is shown as two heating elements l2 located in the chamber 2 in positions clear of the path of movement of the seats.

In the embodiment illustrated in Figs. 16 and. 17 which is suitable where a low flushing tank is to be employed the sterilizing or refreshing chamber 2 is combined with the flushing tank. In installations where there is limited floor space this embodiment would not contain the tank. Each of the panels 5, 6 with the half seats l5 mounted thereon is rotatable about upper and lower pivots 8 and 9 which are fastened to the panels and rotate in the members It and Ilia as in Figs. 14 and 15 and the sterilizing or refreshing unit is shown as two electrical heating elements [2 located in the chamber in positions clear of the path of movement of the half seats. The panels are rotatable in synchronism by operation of one looking handle 2|. For this purpose the cable 20 is extended, is passed through the upper hollow pivot 8 of one panel and down through the upper hollow pivot 8 of the other panel to operate the brake of the other pair of half seats while the lower two pivots are connected by a flexible shaft 24 so that rotation of the one panel produces a simultaneous rotation of the other.
