Fig. '1 is an felevatio l flll View the, 1 "a dentisflsjcuspidor]when 1 invented ,newand useful Improvements in Syringes, of which the following is a specification. V I i i This invention relates to syringes, and n particular to that type of syringe use dv n dental and surgical work for flushlng or cleansing a cavity or Wound with warm water, or with an antiseptic or medicinal solution. 15
For example, in filling teethjiti is neces sary frequently during the drilling of a;
cavity for the dentist to ascertain the progress of the work. This is accomplishedby cleansing the cavity of particles produced this kind,
by the drilling by flushing or syringing the samewith warmwater "The common ap-v pliance for this purpose; namely-a small bulb syringe, has several ser ous defects.
The dentist must attend to th e filli ng of the by, immersing the nozzle in warm syringe wait for the collapsed bulb to water and fill by suct'ion w The water is ejectedfrom,
the syringe by squeezing the bulb and this act often displaces thenozzle so .that the stream is not properly; directed, necessitatsing a refillingof the syringe. The bulb by reason of constant flexing soon develops cracks and leaks and must" be fre'qiie'ntly renewed. The bulb syringe is consequently a source of annoyance .and delay to, the dentist in his work. It I V Objects of the present invention. arei fto producea syringe which can be used 'con .Lf; tinuously without refilling, to provide fluid atria constant temperature nearflthe nozzle of the syringe, to positively control,..th]e force and fiow of"the -str eanr1 from the Y syringe, to provide means for gripping and holding the syringe to insure the proper ed1- recting of the stream, and in general "to overcome the defects of previous" deviesfoif filhe invention comprises affluidichamber r with, a fluid inlet thereto'and two outlets,
one of which communicates with a: nozzle. The fluid chamber may beq'enlargedltoproe vide' a reservoir in which cas'e fthe outlet not ;connected to the nozzle becomes 7 an overflow. The invention isfurther characterized trolling theffor'ce by se v .riw s"f f d fame li i fluild it n a heem t or, 1-1 through the nozzle." c ,4

receptacle. A similar tubular member 26 has a reduced portion 27' telescoping Within inember' 22. A cap nut 28 is screwed upon the end of the-reduced portion 27 of slidable member 26"closing theborethereof and acting as'a stop member to prevent the separation oftelescoping members 22 and 26. An elongate Washer 29 is looped over stop 28, one end receiving the reduced end of slide 26 through hole30and the other end receiving inhole 31'the' nipple32 upon stop nut 28.
-jNear theouteriend of telescoping member 26arejannular flanges or collars 33 and 34, similar to flanges 23 and 24' n member 22. Surrounding telescoping members f22 and, 26 andheld between flanges 24and 3 1 thereon is an elastic tube 35, preferably of rubber, for preventing leakage Surrounding'tubes35fand confined between flanges 23 andi38 is a coil spring 86 normally forcing members 22 and 26 apartvand holding stop nut 28. pressing one end of Washer 29 tightly against the inner end of member 22. At-
tached to slidable member26 and abutting flange '83.-on.the side opposite the spring 36 is anactuator 25 adapted to be'encircled by the forefinger of theoperator for control ling the valve mechanism. I
The'extreme outer-end of slidable member 27 is screw threaded to receive .a union. nut 37 for attaching nozzles of various kinds. In the l device illustrated, the union mut pressesanextension 38 'against a vvlash er '39 interposedbetween the, extension 38. andthe slidable' memberj26." If desired, separate nozzletips such as 40-may be connected to extension 38 by screwing the same upon/the threaded" end 'ofextension 38, suitable pack ing being interposed (as indicated at 41 to prevent leakage. jAn annular. cup shaped member 42 may be'used to retain the packingu-i ""Theoperation of the device is asfollovvs: The device W l1n not in use is hung upon the edge of thecu'spidorbovvhas previously described, with liquid flowing continuously into 'and out [of the reservoir 5 which is thus kept full at all times. lVhenithe operator vvishes f to use the device, he grasps the .reservoir "5 in his han'd""ex tending his. forefinger over the actuator 25.

When the actuator 25 is drawn back toward the reservoir 5 member 26 slides through member 22 compressing elastic tube 35and spring 36. Just as the nipple-32 'en- .ter's the overflow opening 17, a hole 48 opening into thebore of member 26 is uncovered, ermitting" Water to pass through member 26 and'out through nozzle 4C0. As the actuator 25 is pulled back farther, more'rand more of the "hole 43 is "uncovered'and the overflow opening 17 is proportionally closed by nipple 32'. When the slidemember 264s drawn back to'its extreme limit, hole-431m. completely Within reservoir 5' taking the full flow of liquid While overflow opening-'1; is completely closed, the inner fold of Washer 29. being pressed tightly between hollow member 16 and cap nut 28. VVhen'actuator 25 isrele'ased', springSO forces slidingmemberi26 to the other extreme position and the outlet to the nozzle isagain tightly closed as heretofore described. By properly manipulating slide 26 through actuator 25 very fine graduations of the amount of liquid diverted through the nozzleare possible, particularly if tliehole is made somewhat elongate as-in the form of a slot. The force of the 'streamis controlled'in'a similar manner since the bore of the nozzle is much smaller than the inlet to" the receptacle. When the hole 43 -isso'arranged as to be completelywithin the'receptacle before the nipple enters opening 17, only a sloW trickle or drip occursat the tip of the nozzle sincethepres'sure'of the inflowing'liquid is relieved by the overflow, The flow from the nozzle can be increased by de greesLto powerful jet'by gradually closing the overflow opening 17 as themembe rf26 is.
