JOSEPH F. MILLIGAN, CHEYENNE WYOMING.

SYRINGE.

To all whom it may concern:

"Be it known that I, JOSEPH F.' M1LLIGAN,

a citizen of the United States, residing at Cheyenne, in* the county of Laramie and State of Wyoming, have-invented certain new and useful Improvements in Syringes;-

and I do herebydeclare the following to be a full, clear, and exact description of the invention, such "as will enable others skilled in thepart to which it appertains to make and use the same.

My invention relates to new and useful p improvements in syringe constructions and my object is to-provide means for attach-` ing a nozzleto va flexible bag or body lpor-l tion.

l within the neck of the bag to regulate the i I tected.

flow of the contents fromj the ba A further object is'to 'provi e a. casing for the bag,

A further object is to provide movable side walls in \the casing, whereby pressure may be applied to the bag to force the contents thereof through the nozzle.

A further object is to provide means to normally retain saidmovablesidewalls outV of direct contact with the bag, and, a further object is to provide suitable tablet receiving receptacles on the walls of theA casing.

Other objects and advantages will behereinafter described and more particularly pointed out'in the specification and claims. In the accompanying drawings which are made a part of this application, Figure 1 is. aside elevation of thev syringe complete.`

structed of metal or other suitable material,

such as hard rubber or the like. 4

Attached to the upper end of .the neck 2 is a nozzleB, which is constructed in the usual manner and is threadedfon to the neck 2, aportion of the exterior surface of said ,nozzlev being threaded to receive ,the threads of a cap 11, which ncap is adapted to lit over the opening in the end of the Specification of Letters Patent. Application filed January 25,y 1910. Serial No.

A further object is to provide a valveI whereby-the same will be prol- Patented Feb. 14, 1911.

i tnozzle to prevent leakage when the syringe is being transported or is not in use.

Surrounding the body portion 1 and at- -tached in any suitable manner to the lower end 4of the neck portion 2, is a casing 5, which casingL is preferably constructed of portions of the side whereby pressure may be applled to the body l to expel the contents thereof through the nozzle. The movable sidewalls are slidably mounted at their corners on rods 7, which rods are carried of the casing and in order to normally hold the movable side walls out of engagement with the body 1, springs 8 are placed around said ro'ds, the ends of the springs engaging the movble side walls.

" n or er to ro er1 a l ressure to the movable sidre nialls),I thly) grd) each pro- Videdadjacent their longitudinal centers with a boss or circular rib 9, thereby providing seatsI into which the ends ofthe thumb and finger may be placed when applying inward pressure on the movable side Walls and side walls, th pressure thereon will be equal vthroughout the length of said side walls. To prevent the flow of the contents of the body into the nozzle 3, as is being transported `or tilted to. apply the same to'use, the upper end of the neck 2 is provided with a closure 10, which'is preferably formed integral with the neck, said closure having suitable ports 11 through Awhich the contents of the body may flow and over said ports is disposed a valve 12, said valve when seated over the ports, closing the same and preventing the discharge ofthe contents of the body.

The valve 12 is provided with a depending through a guide 14, the lower end of the stem having a head 15 thereon between which and the guide 14 is placed a lspring 16, said spring being spiral and extended around the stem, the tension of the spring being employed. to normally hold the valve seated 'over the ports in the closure` Secured to or formed integral with the `edge walls of the casing 1 are tubes 17, into medicine, which tablets are to Abe used in connection with the contents of the body 1 for .treating diseases is'particularly designed.

met-also as to thoroughly Aprotect the body, walls 6 being movable,`

by the solid. portion when the syringel stem 13, the lower end of which is extended' for which the syringe as said bosses are'placed at the centers ofthe which is to be placed tablets or the like of 2, sai

f be seen that 'the device can be cheaply, as

Well as strongly and durably," constructed andfinstead of making the casing of metal,

necessary to refill the. same to obtain ditional amount .of liquid.

the same can ,be formed of hard rubber if preferred. It will likewise be seen that a greater or less quantityjof the liquid may be expelledv from the body by increasing or dej creasing. the pressurel on. the side wal o f the syringe, -which is a valuable feature 'over the other forms of syringe in which itis an ad',--

Whatl'claim is: l

1.-"I1i'a syrin'e, the combination with a flexiblebody an a nozzle attached theretog` of-"a casing surrounding said body having the sidewalls thereof formed in sections, one section of each wall adapted to be manually depressed to force the contents of. the body,

, through said'- nozzle and spring means to Ynormally retain the movable sections out of y Contact with said body.

2; A syrin e, comprising the'combination with a iiexib e body, a neck carried by said bodyand a nozzle attached to'said neck; of

a casing surrounding 'said body, the side walls of said casingl being movable, rods upon which the side walls are mounted, and springs 'surrounding said rods and exerting outwardpressure on'the movable side Walls,- whereby the side Walls will be normally held? lout of contact Vwith the body.l

` 3L A syringe, comprising the combination ith a flexible body, a neck carried by said body and a nozzle attached thereto; of a casing surrounding said body having the' side walls thereof formed insections, one

sect-ion of each Wall being vadapted to be depressed,',rods upon which the movable' sections are mounted, springs lencompassing said rods and normally retaining said last referredto sections out ofcontactwth said body, and means carried by said neck to retain the contents of said body until forced outwardly by the depression of said movable sections; y I i 4. In a syringe, the combination with a flexible body member having anozzle at-l tached thereto; ofa casing surrounding said f body having portions of thesidewvallsthcrc: 4of movable, means tonorlnally retain'said movable portionsbut of contact with said body, and additional means to' normallyfre tain the'contents said bodyguntilforcedy outwardly by the depression. of'said movable.

side walls. l

` In testimony whereof- I have signed name tothis specification in the .presence of,

subscribing witnesses.
