The flange 5 for the clutch 4 has, projecting from its front face, an arm 20 (Figs.

An arm of a lever 29 (-Figs. 3, 13 and 14) is mountediiwith a revolving motion, on the eye .of Ithewclutch 4:,at the side-0f thearm' 26, to serve for. fixcable for: working the *di seye; a small; balance member I 30, oscillating 32 onv onetend, and a nose 33 on the other jects overtheclutch,whererin an orifice 34 I tting in, and- 'disatthe prop? 35;.in the support-6 neutralizes the action of the spring the nose is capable of 1 '32, by j the upward movement. of the -seat.

Then it has been fixed in this way, adjust thespring 8 to the desired tension, i, e. until the seat when lowered, rises with the neces- After the chain of the water reservoir has been connected to the arm 29, and the connecting rod 44 (Fig. 2) of the pedal E to the arm 37, the device is ready for working. Thus, when a person wishes y to use the. water-closet, it is sufficient to tread on the pedal E to cause the seat to come gently down, until it is very little above the mouth of the water-closet, as shown in Fig. 2. The movement produced by the pedal causes thev arm 37, fixed to the clutch/1;, to disconnect in the same way the said clutch, i. e. until the projection 24:,

" under the action of the spring in the support 6 fits into the groove in front 22 of'the clutch to take up the action of the large spiral springs 8, and to leave the arm 26 free, or in other words, to release the seat, which can then descend on to the mouth of the water-closet. The downward movement of the seat is slow owing to the action of the oil retarder, in the opposite end of the apparatus, the working of which is described below. As soon as it is in the position shown in Fig. 2, theperson sits, with all his weight, on the scat, lowering itas far as i will go. This causesfthe arm 26, with the :projection 28, at the end of its groove'28,

to press downthe projection 24, under the action of the spring inthe support 6, releasing in thisway theconnection established before with the large spring 8, which again attempts to make the seatrise. At the same time also, i. e. when the water closet is occupied, owing to the slight twist given to the clutch 4 the arm 29 becomes rigidly fixed to the clutch, owing to the nose 33 fitting into the orifice 34 of the clutch 4:. Now, when the person rises from the water-closet, the large spring 8 makes the seat rise again slowly, compelled towmove slowly by the oil restriction; at this point the lever 29 puts the valve of the water discharge into action, and by the time. the seat has reached its highest (position, the prop 35 of the support 6 makes the arm 29 free itself from its connection with the clutch, to return to its original position pullin by means of the chain,

the valve of the disc arge of water. So that all the mechanisn'i of the apparatus is once more in its original position ready to work again.

The oil retarder, just as described and rcpresented in the drawings, is a small veseel 13 ful of oil,.capable of revolving eccentrically round a disc 15 of smaller dimensions, which carries an extensible rod 17, with a side hole 19 at one end and which divides the vessel 13 into two watertight parts, it, therefore, has the same width as the vessel, and accompanies it from its tops in its movements. The retension is caused by the fact of the oil in one part of the vessel, when the seat of the water-closet to which it is fastened, is moved becomes compressed and compelled to pass 'by the side hole 19, of the dividing rod 17 to the other side of the vessel, which it does slowly owing to the compression of theoil. Said retarding mechanism is adapted for use in other connections where the movement of ahinged or pivoted element is to be retarded.

Having thus: described my invention, what I claim as new and desire to secure by Letters Patent is: i r

1. In apparatus of the class described, in combination, a seat; seat raising means tending normally to raise said seat and'to maintain it in upright raised position; manually operable means to render said seat raising means inoperative and allow said. seat to descend into substantially horizontal posi-' tion for occupation; and means, rendered operative by further downward movement of said seat upon the application of downward pressure is removed.

2. In apparatus of the class described, in

combination, a seat'; seat raising means nor-- many to maintain said seat in upright raised position; manually operable means to render said seat raising mcans' inoperative and allow said seat to descend into substantially horizontal'position; means, rendered operative by further downward movement of said seat upon the application of downward pressure thereon, to render said seat raising, means operative to raise said seat again into upright position when said downward pressure is removed; a' water reservoir; means to discharge the water therefrom; fillfl'dllGZLHS whereby said subsequent raising of said seat effects actuation of said water discharging means.

- 3. In apparatus of the class described, in combination, a seat; seat raising means tending normally to raise said seat and to maintain it in upright raised position; manually operablemeansto render said seat raising means. inoperative and allow said seatto descend by gravity into substantially horizontal position; means, rendered operative by further downward movement of said seat upon the application of downward pressure thereon, to render said seat raising means operative to raise said seat again into upright position when said downward pressure is removed; and means to retard the movement of said seat in both directions.

4. In apparatus of the class described, in combination, a seat having a normal upright raised position, spring means tending normally to raise said seat and to maintain it in said raised position, means to render said spring means inoperative and thereby to allow the seat to descend by gravity into substantially horizontal position for occupation, mechanism for retarding said descending movement of the seat, and means for returning said spring means to operative relation with the seat upon further downward movement of the latter by downward pressure thereon, whereby said seat will again be raised when said downward pressure is removed.

5. In apparatus of the class described, in combination, a seat having a normal upright raised position, spring means tending normally to raise said seat and to maintain it in said raised position, means. to render said spring means inoperativeand thereby to allow the seat to descend by gravity into substantially horizontal position for occupation, mechanism for retarding said descending movement of the seat, means for returnmally to maintain said seat in upright raised position, manually operable means to render said seat raising means inoperative and allow said seat to descend into substantially horizontal position, means, rendered operative by further downward movement of said seat upon the application of downward pressure thereon, to render said seat raising means operative to raise said seat again into upright position when said downward pressure is removed, a water reservoir, means to discharge the water therefrom, connecting means for actuating said water discharging means by upward movement of the seat, and clutch mechanism for rendering said connecting means operative by said further downward movement of the seat and again inoperative upon completion of the full upward movement thereof.

In testimony whereof, I have signed my name to this specification.
