VALVE FOR SYRINGES.

UNITED STATES BENJAMIN F. SUTTON, OF BROOKLYN, ASSIGNOR TO PARKER, STEARNS & SUTTON, OF NEYV YORK, N. Y.
VALVE. FOR SYRINGES.
SPECIFICATION forming part of Letters Patent NO. 362,678, dated Diary 10, 1887.
Application filed Septemher20, 1886. Serial No.214,077. (No model.)
To all whom, it may concern:
Be it known that I, BENJAMIN FRANKLIN SUTTON, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Valves for Syringes, of which the following is a specification.
My invention more particularly relates to valves such as are employed in syringes, which to comprise severally an elastic and compressible bulb and suction and discharge tubes extending in opposite directions therefrom.
In syringes the valve-chambers are commonly made of metal, each having a valve-seat r 5 and a passage leading thereto, and the valves have been usually made of loose pieces of metal, which were adapted to close on the seats and which were provided with guiding projections or stems entering the passages below the seats 0 in the valve-chambers and serving to guide the valves. The valve-chambers have also been provided with guards, consisting of prongs or spurs bent inward to overlap the valves, and whereby the valves are held in place in the chambers and prevented from undue move ment in opening. Such valves, which have been made of metal, have been comparatively expensive by reason of the necessity of turning orfinishing them, in order that they may close tightly on their seats; and whenever itbecomes necessary to clean the valves and seats, the guards have had to be bent outward in order to provide for the removal and replacement of the hard unyielding valves. By so bending the guards they soon become broken off.
The object of my invention is to provide a valve for the purpose above described which may be made complete and entirely finished in the operation of molding, and which will re- 0 quire no turning or machine work for completing it, and which may be removed to pro vide for cleaning and replaced without bending or changing the position of the guards.
The invention consists in the combination,
4 5 withavalve-chamberforasyringe, constructed with a valve-seat and apassage leading thereto, of aloose valve provided with an integral guiding-stem entering the passage, the valve and its stem being formed integral of yielding or elastic material.
In the accompanying drawings, Figure 1 is it for use.
an axial section of a portion of the bulb of a syringe with its suction-tube and the valvechamber through which the bulb communicates with the suction-tube, and which embodies my invention, and Fig. 2 is a plan of the valve and valve-chamber independent of the other parts.
Similar letters of reference designate corresponding parts in both figures.
A designates the valvechamber proper, which may be made, by casting, of soft metal, and the soft metal which is commonly employed comprises as an ingredient tin, and will melt at such a degree of temperature that it may be readily cast in iron or other metal molds. 6 3 The valve-chamber has sprung over it at one end the compressible and elastic bulb B,which is held in place on the end portion of the valvechamber by its contractile elasticity, and the suction-tube Ois held in place byits contractile 7o elasticity upon the other end of the valvechamber A.
It is of course obvious that tubes or tubular portions with which the valve-chamber is used may be connected therewith in any suitable manner.
The valve-chamber A has formed within it a valveseat, I), and a passage, 1), which leads to the valve seat and through which the tube O is in communication with the bulb B.
D designates the valve which controls the opening through the passage 12 and valve-scat b, and which is provided with an integral stem or projection, d, entering within the passage 2), and by which the valve is guided in its 8 openingandclosingmovements. ThevalveD is flat or disk-like or of puppet shape, and it and its guiding stem or projection dare formed in oneintegral piece o'fyielding or elastic material-such, for example, as soft flexible india- 9o rubber; and an important advantage ofmaking the valve of such material is that after being molded in proper shape it may be removed from the mold and used in a valve-chamber to perform its proper functions without any eX- pense of labor in finishing the valve and fitting The valve being made of such soft and yielding or elastic material, it is not important that the valve-seat I) should be finely finished, and the valvejwhen made of the ma- 10o terial described will close properly and tightly upon the valve-seat, even though the valveseat may have imperfections and be not truly and smoothly finished.
In order to prevent too great rising movement of the valve D in opening, I have represented guards for holding the valve in place, and in this example of the invention the guards d consist of projections which are formed integral with the valve-chamber A above the valve-seat b, and which, after the valve is in serted in place, may be bent over the valve so as to overlap the same, as shown in Fig. 1, and prevent any such opening or rising movement of the valve as would carry it entirely beyond and out of the way of its seat.
It is frequently necessary to remove the valve from the valve-chamber for cleaning the valve and its seat and the passage b. When the valve is of hard and unyielding material, or even if it consists of a ball of india-rubber, it is necessary to bend outward the guards d, in order to remove the valve, and to bend them back into the position shown after the valve 7 is replaced. Such bending of the guards soon weakens them and they become broken off. Whenthe valve D is of soft and yielding indiarubber, it may be readily changed in shape so that it may be crowded past the guards d in removing and replacing it, and may be there,- fore so removed and replaced without bending the guards at.
Iam aware that a pump-valve has been made of india-rubber and has been provided with a metal stein shouldered and passing through the valve and a top plate thereon and secured in the valve by a nut,.the valve being held in 5 place by aflexible strap connected at the ends to the piece on which the valve seats and at the middle of its length to the valve.
I am also aware that a solid ball-valve of india-rubber has been confined by guards; but, 0 being solid, it could not be so changed in form as to pass the guards: My valve D and its stem d are both made in one integral piece 'of elastic or yielding material, and consequently the valve and the stem are capable individually 45 of yielding, and the stem has a yielding connection with the valve. The guards d are rigid; but the valve, being of fiat disk-like or puppet form, maybe so bent and changed in shape as to pass the guards, and may thus be removed 50 from and replaced in a working position without bending the guards or changing their position.
What I claim as my invention, and desire to secure by Letters Patent, is 5 The combination, with a valve-chamber, A, for a syringe, constructed with a valve-seat, b, and a passage, b, leading thereto, of a loose valve, D, provided with an integral guidingstem, d, entering the passage, the valve and 60 its stem being formed integral of yielding or elastic material, substantially as and for the purpose herein described.
