23 Claims.

Our invention relates to toilet apparatus, and particularly to water closets of the usual type, comprising a fixed bowl and a separate seat. We have observed that in apparatus of this type, particularly when located in public places, the seat is frequently in an unsanitary condition, making the use of the apparatus undesirable and unhygienic. One object of our invention is to construct toilet apparatus in which the seat, when in use, is provided with a sanitary cover which is placed on the seat automatically before use and removed automatically after use. Another feature of our invention is the provision of mechanism for withdrawing the seat to an inoperative, and preferably concealed, position when the apparatus is not in use, thereby facilitating cleansinfJ of the bowl. The seat is then retained in this inaccessible position until required by a user, with the result that the seat is at all times in a clean condition. Other objects and advantages of vour invention will appear more fully from the follow ing description. v Y

We will describe one form of toilet apparatus embodying our invention, and will then point out the novel features thereof in claims.

In the accompanying drawings, Fig. 1 is a view showing, in front elevation, one form of toilet apparatus embodying our invention. Fig. 2 is a vertical longitudinal sectional view of the apparatus shown in Fig. 1. Fig. 3 is a detail view oi a portion of the apparatus shown in Figs. 1 and 2, with the parts in different positions. Fig. 4 is a top plan view of the seat of the apparatus shown in Figs. 1 and 2, with a sanitary cover in place. Fig. 5 is a side view of a sanitary cover embodying our invention. Figs. 6 and 7 are detail views of a portion of the apparatus shown in Figs. l and 2, and also embodying our invention. Fig. 8 is a diagrammatic view showing the electric circuits for controlling the apparatus shown in Figs.l 1 and 2. Fig. 9 is a detail View showing a portion of the apparatus illustrated in Figs. 1 and 2.

Similar reference characters refer to similar parts in each of the several views.

Referring iirst to Figs. 1 and 2, the reference character A designates a water closet bowl of the usual form, which may be provided with flushing mechanism forming no part of our present invention and not shown in the drawings. Located in rear ofthe bowl A is a supporting frame C comprising two side plates l, a bottom plate 2, a top plate 3, and a back plate 3'7. Journalled in the plates 2 and 3 is a drive screw 5 operated by some suitable means, such as an electric motor M. The drive screw 5 operates a movable seat B,

capable of assuming a position on the bowl A` to accommodate a user. As here shown, a block 6 is threaded on the screw 5 and is provided with a cross bar ,7 which enters slots 50 between ribs l on the confronting faces of the side plates 1 of frame C. Rotation of screw 5, therefore, moves block 6 up or down depending upon the direction of rotation or the motor. Pivoted on the cross bar 'l is an arm 9 which is biased inv a counterclockwise direction, as viewed in Fig. 2, by springs 8. The seat B is hinged, at its rear end, to the free extremity of arm 9. l l

The reference character 20 designates a slide rod reciprocable in two guides 19 attached to the back plate 37 of the frame C.` Attached to the slide rod 20 is a collar 2l, and between this collar and the upper guide 19 is a spring 22 which urges the slide rod to a lower position in which the collar 21 engages the lower guide 19. When the block 6 occupies the position in which it is shown in the drawings, the block engages a projection 38 on the sli-cle rod 20, holding this rod in', an upper position in which the rod engages the plunger 36 of a switch L and opens contact Ell- 35. g

' Located above the bowl A is a magazine D 'containing a supply of r`sanitary covers E, one oi" kwhich is automatically placedupon the seat B as the seat moves from the position in which it is illustratedin Figs. 1 and 2 to its operative position on the bowl. As best shown in Figs. 4 and 5, each cover E comprises a iiat main sheet El, provided with a centrally located hole E3, so positioned that when the main sheet overlies the top of the seat, the hole E3 registers with the usual opening B3 in the seat. We prefer to use a seat B having its front edge B1 substantially straight and provided with bevelled corners B2, and to construct each cover E with a pocket E2 formed by a downwardly turned flap integral with the main sheet El and united to the main sheet by a pleated portion l2 (Fig. 5) to permit the cover to be folded iiat, while allowing the'front edge of the seat to enter the pocket E2 without tearing, the cover. We prefer to construct the coversE of thin paper, but any other suitable material may be used.

A supply of the covers E is placed in the magazine D with the pockets of the coversat the bottom andrear. The coversY may be supportedk on pins 1G and are preferably urged by a spring 16 toward` the-back of the magazine which: is open at the lower. portion; asfbest'shown in Fig; 2r

The lower end of slide rod 20 carries a plate 28 (Figs. 2 and 9) to the free edge of Whichis rigidly attached a cross pin 38 passing through openings in the side plates 1 of frame C and cooperating with the lower surfaces 2i of these openings. Rigidly secured to the outer ends of this cross pin 38 are two lingers 25 and the parts are so proportioned that when the slide rod occupies its upper position, as shown in Fig. 2, the tips 25a of fingers 25 enter the pocket E2 of the rearmost cover E in the magazine D, and serve to guide the seat B into this pocket as the seat descends to its operative position on the bowl.

The parts normally occupy the positions in which they are illustrated in Figs. 1 and 2, from which it will be seen that the block 6 is holding the slide rod 20 in its upper position so that the fingers 25 enter the pocket in the rearmost cover E in magazine D, and the seat is immediately above this pocket. If now, the motor M is operated to drive the block 6 downwardly, the slide rod 20 also descends, and the forward edge of the seat enters the pocket of the rear cover E in the magazine. As the downward motion of the seat continues, the edge B1 of the seat fits snugly into the pocket E2 and automatically removes the cover from the supporting pins lo. The downward movement of the slide rod 20 also permits the iingers 25 to drop out of the pocket in the cover E, and the fingers then assume the positions indicated in dotted lines in Fig. 2. The seat B continues its downward motion, carrying with it the cover E, which is spread smoothly over the top oi the seat by flexible rubber strips 14 and 15 attached to the edges of the magazine D. As the seat moves downwardly, it is guided by an arcshaped member 26 to the position in which it is shown in Fig. 3, and in which the apparatus is ready for use. It will be observed from inspection of Fig. 3 that in its lower position, the arm 9 which carries the seat engages the plunger 30 of an electric switch G which will be described in detail hereinafter. As a result, the rear end of the seat is raised slightly above the bowl so that the weight of a person using the apparatus will force the seat downwardly and depress the plunger 30 of switch 7G.

Hinged to the lower side of the magazine D is a leaf 17, one function of which is to conceal and protect the mechanism behind it. To the lower edge of this leaf is attached a strip 18 which engages the top of the seat B when the seat is in its operative position. During the downward movement of the seat B, this strip slides over the seat and cover without interfering with these parts. If, however, the motor M is now operated to move block 6 upwardly, seat B is restored to its inoperative position, and during this return motion, the strip 18 engages the cover E and holds it while the seat is withdrawn, whereupon the used cover is deposited in the bowl A, and may be flushed away.

Referring now to Figs. 6 and 7, the switch G comprises a hollow insulating housing containing two vertically extending electro-conducting slides 27 in each of which is a slidable metallic member 29 provided with a slot 29a. A plunger 30 carries a contact plate S1 and a strip of insulation 32, the opposite ends of which plate and strip enter the slots 29a in members 29. A spring 33 biases plunger 30 upwardly, and members 29 are thereby urged against stops 27a so that the switch G is normally closed. If plunger 30 is depressed the switch opens, and if the plunger is depressed still further, members 29 are moved downwardly in the slides 27 in which they are held lightly by spring strips 23 (Fig. 7). A very op movement of the plunger will again close the switch, and if the plunger is entirely released the parts return to the positions shown in Fig. 6.

The apparatus may he controlled by a starting switch indicated diagranimatically at S in 1. This switch contains a contact which may be closed momentarily and may he an ordinary push button, a coin-operated contact or any other form of circuit controller.

We prefer to operate the apparatus oy a motor M of the single phase alternating current type comprising an armature fic and a i7 and having the characteristics of operating in opposite directions upon currents ci opposite relative polarity, but functioning, if the motor has once commenced operation in either direction, to continue to operate in the same direction, if the relative polarity of the currents supplied to the motor windings is reversed.

For the purpose of reversing the relauive polarity of the current supplied to the motor windings we provide a quick-acting reversing switch R (Fig. l) having an operating lever R1 in the path of travel of the block 6 and arranged to be moved to one position as the block ascends, and to the other position as the block descends.

Referring now to Fig. 8, and assuming the parts to occupy the positions shown in Figs. i and 2, it will be seen that switches L and S are open but switch G is closed. Current therefore flows from a suitable source of energy, such as a generator K, through switch G to a slow pick-up relay J. As a result the relay is energized, but the motor M is deenergized, the armature and field circuits both being open at switches S and L. If, now, the starting switch S is closed momentarily, current flows from generator K, through switch G, front contact 45 of relay J, and switch S, thence directly through iieid 47 of motor M to generator K, and also through reversing switch R and armature 46 of motor M to generator K. The parts are so arranged that the resultant operation of motor M drives the seat downwardly to its operative position, as described above, placing a cover E upon the seat during this movement. As soon as this movement commences, switch L closes, and the motor circuits are thereafter held closed independently of the starting switch S, which opens after a brief interval. As the seat moves downwardly, block 6 trips the reversing switch, reversing the polarity of the current supplied to the armature s6, but since the motor is then in motion the motor continues to operate in the same direction. When the seat reaches the position in which it is illustrated in Fig. 3, switch G is opened and the motor circuit is interrupted, so the motor immediately stops. Relay J also becomes de-energized. If, now, the seat B is depressed, as by the weight ci a person using the apparatus, the plunger S0 of switch G is depressed far enough to move the members 29 of this switch away from stops 27, so that the return of the plunger when the user leaves the seat again closes switch Gf. When this happens the circuit is again closed for relay J, and after a time interval the relay closes its front contact ll5. Since switch L is now closed, motor M is energized, but since switch R is reversed, the motor now drives the seat back to its inoperative position, permitting the cover to enter the 1cowl, as previously described. During the upward movement switch R is tripped, but the motor continues to operate in the same direction until the parts reach the positions shown in Fig. 2, whereupon switch L opens, to deenergize the motor and'restore the apparatus to normal.

One purpose of relay J is to prevent the withdrawal of the seat until-the expiration of a brief interval of time after the user has left the seat.

In actual practice, the motor, frame C, 'and all moving parts will usually be concealed by a door or housing which has been omitted from the drawings to illustrate the parts more clearly.
