BENJAMINEF. KELLER, or CAMDEN, OHIO.
SYRINGE.
To aZZ w/wm it may concern:
Be it' known that I, .BENJAMINE F. KEL- LER, a citizen of the United States, residing at Camden, in the countyof Preble, State of Ohio, have invented certain new and useful Improvements in Syringes; and I do hereby declare the following to be a full, clear, and
exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
"l'his invention relates to syringes and more particularly to those for use in the practice of veterinary surgery, and has for its object to provide a syringe equipped with separate inlet and discharge openings, so that a number of charges may be forced from .the syringe without removing the nozzle specification and in which like numerals of as shown at 7.
r'eference indicate similar parts in the several. VlBWS FIgIlIQ 1 1s a longitudinal section through the syringe, Fig. 2 is a transverse section on line 22 of Fig. 1.
Referring now to the drawings, the present invention comprises ahollow cylindrical barrel 5, having a laterally opening, intake port 6, surrounded by an outwardly extending. flange 7 threaded interiorly at its outer end,
Within this threaded portral opening 9, for which there is provided a flap valve 10, of leather or other suitable material, secured at one side to the inner surface of the disk, and thus arranged for inward movement into open position.
A cap 11 is screwed upon the outer end of the flange 7, the thread 7 being pressed or spun in the metal of the flange, to present both interior and exterior threads, and the cap has an outwardly extending nipple 12 which receives a flexible hose 13, the passage Specification of Letters Patent.

through the nipple communicating with the Patented April 30', 1907.
' interior of the flange through an opening in the cap 11, as shown.
A piston rod 14 is engaged in the removable rearward end 15 of the barrel for sliding movement, and has a stirrup-shaped handle 16 at its rearward end. The forward end of the piston rod is reduced, as shown at 17, and has engaged therewith a pair of metallic washers. 18, between which there are engaged a pair of flexible suckers 19, of annular. rorm, having their outer edge portions turned in opposite directions against the inner periphery of the barrel, and a confining nut 20 is engaged with the extremity of the reduced portion 17..
A discharge opening 21 is formed inthe forward end ofthe barrel 5 and is surrounded by an outwardly extending flange 22, spaced outwardlyfrom the opening, and; provided which receives the interiorly threaded rim 23 carried by the inner end of a nozzle 2 1. A sleeve 25 is carried by an outward] extending disk 26 at the base of thenozz e, within the inclosure of the rim 23, which is carried with an exterior thread 22 at its'outer end,
by this disk, and when the nozzle is in dposition, this sleeve 25 engages the forwar end of the barrel, surrounding the opening 21,
and secured at one sidewithin the sleeve 25,
there is a flap valve'27, thus arranged for outward movement.
It will be seen that the i e 13 may be dis.- posed in a supply of liquid? when rearward movement of the iston rod will suck the liquid into the barre forward movement of the piston rod'forcing it out through the nozzle 24, and this operation may be repeated, until the supply of liquid is exhausted. The opening 6 is located adjacent to the forward end of the barrel, as shown.
What is claimed is: A syringe comprising a barrel provided with inlet and dlscharge openings formed therein; a piston slidably mounted in the barrel; a piston rod connected with the piston; an outwardly extending flan e surroundin the inlet opening and threaded interiorly and exteriorly at its outer end; a disk dis osed within the flange in engagement witli the inner threads thereof, said disk having an opening formed therethrough; an inwardly movable valve secured to said disk in posil movably engaged with said last mentioned Witnesses:
-posed within said last-mentioned flange, said tipn to open and close said opening; a cap resleeve surrounding the discharge opening; to
