Application filed March 31,

To all whom t concern:

Be it known that l, ERNnsT G. FRIEDRICH, a citizen oit the United States, and a resident of the city of Indianapolis, county of Marion, and State of indiana, have invented certain new and useful Improvemen'ts in Sanitary Toilets, of whichthe i'ollowing is a speciiication.

Wy invention relates to improvements in toilet seats and seat covers in general and more particularly to means for washing and cleansing' such seats after usage.

The principal object ot my invention is the construction of a toilet seat that will be washed and wiped after cach usage thereof. A, nl'nrther object is to provide `a seat that will be washed and wiped while in an upright or 'vertical position. A Jfurther ob` ject is to provide a seatthat will be automatically washed by a predetermined iiow of water whenever the seat is raised or closed and which must be wiped before seat can be released for further usage. A further object is to provide a seat controlling mechanism that may be readily adapted for operation by a coiiiintheslot mechanism. A further object is to provide a mechanism that shall be automatic in action for closing' and washing and manually operated tor release and which shall also be simple and inexpensive of construction and adapted lto application on standard toilet fixtures.

lWith these objects in view, and such others as may appear, my invention relates to details of mechanism and construction illustrated in a preiierred `ll'orm in the annexed drawings, it beine' understood that such modification thereof may be made as shall come within the spirit of the appended claims. p

1n the drawings Figure 1 is a `trout view ot the device with seat in closed position. Fig. 2 is a plan view. Fig'. 3 is a vertical side elevation. Fig. 4 is an enlarged view o'l the .coin controlling` mechanism, Fig'. 5 being' a side elevation of said mechanism,

' and Fig. 6 ascctional.' plan view oi the coin slot. Fig'. is an enlarged fragmentary sectional View oni line 6-`G of Fig. 1. Fig. S is a partial front elevation of an alternative construction ot thelwiper mechanism, Fig'. 9 being a sectional plan view of the water controlling' valve in closed position, and Fig. 10 a sectional plan of valve in open position.

Specification of Letters Eatent.

1919. Serial No. 286,504.

Referring more particularly to the drawings wherein like numbers refer to like parts throughout, the numeral 10 indicates a toilet bowl ot' any conventional design to the rear portion 11 ot which a vertical cover or housing 13 is iixedly attached as by bolts 12. The cover 13 is of bos-like construction having a front cover or Jface 14 through which an arcuate recess 15 is formed for the reception of the seat 1G. The seat 16 is preferably cut away at its inner portion as at 18, leaving a connecting section or neck 17 to support the middle portion of cover 14, the seat being hingedly connected as at 19 to the supporting' extension 20 of cover Patented July 13, 19120.`

13. SeatlG may be provided with an inner and outer flange or rib 21-21 to assist in sealing the opening 15 against the leakage of water therethrough.

Centrally located in cover 13 is a stud 22 which may be provided with a reinforced bearing 23 carryinga projecting` pin 24 to engage one end of a helical spring 25, the opposite end oil? said spring beingV connected to a pin 28 on a sleeve 27 surroundingr a portion of the stud 22. Fixedly attached to sleeve 27 is a Alexible element 29 adapted to be wrapped or wound on said sleeve as at 26,- the opposite end of said flexible element being attached for wrapping engagement upon a roller 37 attached to shaft 36 rotatably mounted within an extended hous ing or coin box 34 attached to the upper portion oiE cover 13. Fixedly mounted on sleeve 27 is a wiping` arm 30 carrying a wipingV element 81 oil any suitable flexible material, the outer extremity oi arm 30 being' carried and `guided in a slot 32 formed in the periphery of cover 18. Arm 30 may be backwardly extended as at 30 in order to `give a double wipingcontact on the face ot the seat.

,Fixedly attached to shaft 36 is an arm 35 carrying a handle or linger grip 39 projecting through an arcuate slot 38 in one face of the housing; 34. Pivotally mounted on arm 35 as at 41 is a pawl 40 riding; through an arcuate housing 42 Xedly mounted on a partition 47 within said housing 34. Communicating; with the arcuate housing 42 is a coin receiving opening 43 and a spurious coin'or slug discharging duct 44 communicating with an opening 45 through one wall of said housing 34, acceptable coins being discharged Jfrom housing 42 at vits extremity 46. The free end of pawl 4Q is arcuately adapted to the circumference or" a coin 48.r An opening 4:9 liav` ing a reducedportion 50 is formed in the lower edge of 'housing Zl2 through which coins or slugs olf smaller diameter or yless thickness than the prescribed coin will pass and be ejected through opening 45, while an acceptable coin will restrin thearcuate end of pawl 40 and will support said pawl during ,its passage' over the enlarged portion i9 of said slot; "if an attempt is made to operate the device without a suitable coin,

` the point 52oi`pawl 4L() will drop by kgravity arm may be provided with an electrically li'eatable coil or elementy 53 connected by a -wire 54 to any outside source of electric current, as at 55, an arcuate :contactshoe 56 beingslidablygengageable with said coil, said shoefbeing electrically connected as at 57 to the opposite side oi said `electric circuit, con.-

y tact between-the element53 and shoe 5613eingbrokenwvhenarm.30 is in retracted or inoperative position.` l The seat 16 isfraised from its horizontal 'position 16 to its closed position withinthe cover 13 by any suitable meansVasa spring `65 or counterweight (not,shown),and is re* tained 1n closed position "by a pawl62 engaging a notchor recess V63 in the outer pe-VV .riphery of said seat, said pawl being pivotally connected to a lever 60 pivotally connected as at 61 to the .housing 3d, a lug` 64 being iixedly mountedon the liexib'le element 2.9to engagewiththe lever 60 to release said seat 'by disengaging itffrom paw-l 62.

YVater is admitted through any suitable pipe 66 to which is attached a valve housing 68 with, preferably, a conicalseat` 69- atc one-portion of its bore, the yremaining portion 71 of the bore lbeing straight A valve plugr82 having` asimi-l Y larv conical por-tion 70 andstnaight portion .72 is mounted with-in the bore Votthe valve, Y said plugfhaving a central bore/i4 andan annular chamber .S1 for the reception of a helical spring 79..' Within the bore 74 is loosely ittedfa. plunger 75 Vhaving an enlarged head 76, Vsaid plunger engaging a lighthelical spring 8O within said.borea bypass 77-conneeting saidborefM with said l inletpipe `66 when said valve is closed. Wa-

ter is discharved `from said valve through an outlet pipe 67 and may be ydistributed over Y 13 by the spring 65.

vsuitable coin within the coin slot the lever hythese Letters Patent is:
