SPECIFICATION forming part of Letters Patent No. 384,087, dated June 5, 1888i (No model.)
.To all whom it may concern:
Be it known that I, WILLIAM SOOTT, of the city of Malden, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Operating- Levers for Valves, 8mo., of which the following is a full, clear, and exact description.
This invention relates to levers more particularly designed for operating-valves of water-closet and other tanks, although, as will be Obvious from the description hereinafter given, the levers are applicable to other purposes,and therefore it is not intended to limit the invention in this regard.
The invention more especially relates to the class of Operating-levers shown and described in Letters Patent of United States issued to me, reissue dated October 20, 1885, No. 10,653;
'originals dated December 1, 1885, and Nos.
331,556, 331,557, and 331,558, to which reference is hereby had.
The invention consists of two reciprocating levers, one of which is suitably adapted-to be used as an operating-lever, and the other is suitably connected to the valve or other contrivance to be operated in combination with a swinging toe-piece dependent from the operating-lever, and which is adapted to abut on it in two directions at an angle to each other` and in each position of abutment has a bearing and working face to work on, and to escape from abearing and working face of valvelever in each direction of the reciprocating motion of the operating-lever, and all so as to` secure a reciprocating motion of the valvelever in each direction ofthe reciprocating motion of the operating-lever, substantially as hereinafter described. y
In the drawings, forming part of this specication, Figure 1 is a side elevation of the lever contrivance of this invention, showing it in its normal position. Fig. 2 is a plan View. Fig. 3 is an end elevation and vertical section, line 3 3, Fig. 1.v Fig. 4 is a horizontal section, line 4 4, Fig. 1. Fig. 5 is a vertical section, line 5 5, Fig. 1. Fig. r(is a section, line 7 7, Fig, 6, as hereinafter appears. Figs. 8, 9, and 10 are severally side elevations illustrating different positions of the lever hereinafter described.
In the drawings, R and U are respectively the valve and operating levers of the lever Fig. Gis a view in detail, andV the levers are used-aa for instance, for opening and closing avalve (not shown) of a watercloset tank, (not shown,) as fully shown and describedin the Letters Patent referred to. The valve (not shown) is connected to one of the ends ofthe valve-lever R, and the operating-lever U at one end, U2, is suitably and as well known connected for being operated, and at the other end it has a weight, Y, arranged for adjustment. Each lever R U swings in a vertical plane, and the operating-lever U is above the valve-lever R, and otherwise,all except as hereinafter described and constituting this invention, is well known and therefore needs noparticular description herein.
The operating-lever U in its normal position, Figs. 1, 2, 3, at, and 5, rests against the vertical face of a stop, B2, of the stand S, suitably located therefor, and it is swung in one direction by forcing its operating end U2 downward againstits weighted end, (the upper edge of the stop B2 determining the extent of such swing,) and in the other and opposite direction to return it to its normal position from the action of its applied weight, as stated.
T2 is a stop of the stand S, suitably located to limit the swing of the valve-lever in either direction, and cooperating in one directionthat is, in the downward movement of its end connected to Valve-with a radial projecting lug, R2, ofthe valve-lever.
Each lever R U has a nose projection, T and C2, respectively. The nose T of valve-leverR has bearing and working faces f2 and n, and the nose C2 of the operating-lever U has bearing and working faces 0l2 and a2 to bear and work when the operating-lever U is swung in one direction-that is, in its direction of swing produced by forcing down its operating end U, the face d* of the nose C2 of the operatingleverU on the facef2 of the noseTof the valveleverR-and when the operating-lever islswung in the other and opposite direction-that is, in its direction of swing'produced from the action IOO of its weighted end to return' it to its normal so working to escape from each other and leave the valve-lever free to return in the one instance to a rest by its lug R2 against the stop T2 of the stand S, and in the other instance to a rest by the bearing and working facef of its nose T against the bearing and working face cl2 of the nose C2 of the operating-lever, which lever, and also the valve-lever, in that instance, are in their respective normal positions.
The nose Cof the operating-lever is a swinging and dependent toe-piece, hung and swinging at its upper end portion upon a horizontal pin, a4, of and between two vertical ear-pieces, a5, of the lever, and at its lower end portion it carries a horizontal projection, a, preferably provided with a friction-roller, a7,which directly makes the bearing and working faces d2 a2 of the lever U and crosses horizontally the vertical plane of the bearing and working faces f2-n of the valve-lever which meet at a more vor less acute angle having its apex m2 uppermost.
The upper end of the dependent toe C2 has two faces, ia a", at an angle to each other and located for separate abutment against a face, al, of the operating-lever U, and this face a10 is opposite to and above the faces as a", and said face am of the lever U and said abutment faces a8 a therefor of dependent toe C? are situated in relation (the face al to the faces as a", and the faces a8 a9 as to each other) for the y face a9 of the toe to be in abutment on the face al of the lever when the lever is on its return movement and the face a2 of the toe is at a bearing and at work on the working and bearing face n of the valve-lever to raise the valveconnected end of said lever, and to be out of abutment at all other times, and for the faces as al,10 of dependent toe and its carrying-lever U to be in abutment on each other when the lever is on its swing from its normal position, and either for the whole or for a portion, preferably the latter, of the then travel of the bearing and working face d2 of the dependent toe C2. over the bearing and workin-g face f 2 of the nose T of valve-lever.
In the normal position of the levers R U the dependent toe C2 of the operatinglever rests by its face d2 against the face f2 of the valvelever, and the. toe at this rest is at a vertical angle of inclination, and one more or less parallel to the vertical angle of direction of said face fz of the valvelever, and preferably7 the abutmentface a8 of the dependent toe C2 is ont of contact with the abutment-face al of the operating-lever. Now on depressing the end U2 of the operatinglever its toe O2, by its face d2 resting on the face f 2 of the nose T of valveL lever, rides up on said face, the toe C2 as it so rides up swinging on its centerpin a, and finally coming to an abutment by its face a8 on the face am of the operatinglever U, on which, continuing the swing of the operatinglever, the end of the valve-lever carrying the toe Tis depressed. This raises its opposite and vvalveconnected end until the workingfaces d2 f2 of the noses ol operating and valve levers escape from each other at the apex m2 of the vvorking-iacesf2 n of the valve-lever; the depending toe-piece of operating-lever is then left free to swing and the valve-lever to return, coming to a rest by its lug R2 against the stop T2 of the stand S, and the swing of the operating-lever is then arrested by the abutment thereof against the upper edge of the stop B2 of the stand S.
Fig. 8 illustrates the position of the operating and valve levers at the pointof escape at their working-faces]n2 nfrom each other, and Fig. 9 the position of operating and valve levers after the escape of their said workingfaces and the valve-lever has swung to a rest against the stop TQand the operating-lever to a rest against the upper edge of stop B2 of stand. Now on releasing operating-lever for its return to its normal position, Fig. l, its swinging toe, then being free from contact with the valve-lever, comes to a rest by its bearing and working face a against the bearing and working face n of the valve-lever, which forces the toe into an abutmentI by its face a against the face am of the operating-lever, on which, continuing the swing of the operating-lever, the toe C2 then rides up the working-face a of the valve-lever, depressing the nose end of said lever and raising its other end until the then working-faces a2 n of the noses of operating and valve levers escaping from each other at the apex m2 of the working-faces n f 2 of the valve-lever, the dependent toe or nose Czis left free to swing and the valve-lever to return to its normal position with the dependent toe at rest by its face d2 on its face f 2 and the operating-lever at rest against the vertical face of its stop B2 on the stand.
Fig. 10 illustrates the positions of operating and valve levers when their working-faces a2 u are about to escape from each other, as just above described.
In the operation of the levers the one upon the other, as described, the operating-lever in one direction of its movement works by one face, d2, against the face f2 of valve-lever and then escapes therefrom, leaving the valvelever free to return, and in the other direction of its movement it works by its face a2 on the face u of the valve-lever, and the face a2 is opposite horizontally to the face cl2, by which it is worked on the valve-lever in its previous movement and then escapes therefrom, leaving the valve-lever again free to return. This, as is obvious on the movement of the operating-lever in each direction of its reciprocation, secures a reciprocating motion of the valvelever, and consequently two separate and distinct operations of the device or contrivance to which the valve-1ever is connected are secured for one reciprocating motion of the operating-lever; or, in other words, if connected to a valve an opening and a closing, followed by another opening and a closing of the valve, 'form one operation or reciprocation of the opperating-lever.
The angle of direction of the abutment-faces aS a of the swinging and dependent toe C2 of the operating-lever relatively to each other and to the direction of the abutment-face al", therefor of the operating-lever, preferably for the purposes of a valve to a water-closet tank, is such as to secure a greater length of swing of the valve-lever on the return inovei ment than on the forward movement of the operating-lever, thus effecting in the supply of water from the tank to the closet what is known as preliminary and after77 Washes of the bowl. The angle of direction of the abutmentfaces a8 a9 of the dependent toe C2,
as well as the direction of the abutment-face:
am of the operating-lever therefor, obviously may be varied relatively considered so as tover preferably, in order to render the ride of the parts more easy and free, is made more or less curving, Figs. 1, 8, 9, and 10.
Having thus described my invention, what i I claim, and desire to secure by Letters Patent, 1s-
In combination, a reciprocating and operating 1ever,U, having an abutment-face, am, and a swinging and dependent toe, G2, with abutment-faces as a at an angle to each 'other for said abutment-face al", and with bearing and working faces d2 and `a2, a lever, R, having bearing and working facesf2 n at an angle to each other to be acted upon by the bearing and working faces d2 a2 of the operating-lever U, and fixed stops to arrest the movement of said levers, substantially as described, for the purpose specied.
l In testimony whereof I have hereunto set my hand in the presence of two subscribing wit nesses.
WILLIAM seorr.
