provide a neat'compact dental syringe whichl has a means for 'readily adding an antisep- -tic salt, disinfectant or the like to water passing through the syringe.
l@ Another object is toprovide a valve for said syringe with a neat and simple means for operating the same which is not likely to get out of order. These and other ob.
jects are accomplished by my device which is fully described in the following specification and shown in the accompanying drawing in which:
Figurel is a top plan view of a syringe embodying my invention; and w Fig. 2 is a partial longitudinal section of the same.
The syringe as illustrated comprises a body 10 having inner and outer chambers 11 and 12 separated by-g,;ineans of a valve 13 which is normally held upon its seatV by means of a spring 14, the outer end of the valve stem being slidably mounted in the cap 15.
The inner end of the valve stem 16, terminates ad'acent a flexible diaphragm 17 which may e made of any suitablematerial as rubber and is lheld about its periphery by means of its cap 18. `A plunger 19 has a head 20 extending through the cap, said head lying immediately over thJe end of the valve stem 16 so that pressure exerted upon the plunger 19, as by means of the lever,21
which is hingedly mounted at 22,.is transmitted through the flexible diaphragm 17,
thereby lifting the valve 13 off its seat.l A
A .tube 27 counicates .with the inner chamber 11 and is' adapted to hold a stick l or pencil of antiseptic salts or other dis- 5 infecting material and to hold the same in said inner chamber so that water passing through the same will slowly dissolve this antiseptic material-and will carry it out through the nozzle 24 so that a dentist 60 using the same may force this solution in a inestream around theroot of a tooth which it is desired to treat. The stick 28 is inserted through the end of the tube 27, a spring 29 is then inserted behind it so as to 65 normally hold the forward end of the stick in the inner chamber 11 while a cap 30 retains the spring in the tube.
While I have shown and described certain embodiments of my invention, ,it is to. be understood that it is capable of many modiications. Changes, therefore, vin the con-y struction and arrangement may' be made f without departing from the spirit and scope of the invention as disclosed in thel appended claims, in which it is my intention to claim -all novelty inherent in my invention as broadly as possible in view .of the prior art.
I claim: l i
A so 1. A syringe comprising a body having v inner and outer chambers, a valve between said chambers, a 4spring normally holding` said valve' on its seat, a-.lever for lifting said valve, a pipe leading from one of said chambers and adapted to be connected to a source of water supply, a nozzle communieating with the othery chamber, a tube communicating with said other chamber adapted to h old a pencil of antisepticl salts, and
`a spring for pressing said pencil into said chamber.
2. A syringe comprising a body havlng inner and outer chambers, avalve between said chambers, a spring normally holdin said valve onl its seat, a lever for lifting sai valve, a'pipe leading from one of said vchambers and adapted to be connected to a source of water supply, a nozzle communicating with the other chamber, means for gradually 4100 feeding a solid chemical to said other chamber, a flexible diaphragm adjacent the end of said valve, and a. plunger on the opposite, side of said diaphragm for operating sald valve.
