MEDICINE-HECTOR.
To all whom it may concern. I
Be it known that we, JAMES J. HARmsoN and ALONZO B. CnA'rriELn, J12, citizens of the United States, residing at Vichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful in lVIedicine-Ejectors, of which the following is a specification, ret'erence being had therein to the accompanying drawing.
This invention relates to a device ldmwn as an applicator or insuttlator for the inpowder for the local treatment of diseases designed that the patient can administer in a simple, convenient and sanitary manner, and without the attendance of. a physician, the remedies which may be prescribed for the particular diseased condition. The device is of that type comprising a reservoir barrel for holding the medicinal powrel in which is a reciprocatory plunger or piston that is manipulated to eject therefrom a charge to the afflicted organ.
The invention has for one of its objects to improve and simplify the construction and operation of devices of this'character so as to be reliable and cflicient'in use and conveniently manipulated, and at the same time be comparatively easy and inexpensive to manufacture. I
Another object of the invention is the provision of an improved cut-.otl valve between the charge and reservoir barrels in connei-s tion with the ejecting plunger or piston.
With these and other objects in view, the invention comprises the variousnovel teatures-o fcmfitruct-ion and arrangement of parts Which willbe more fully described hereinafter and set forth with particularity in the claims appended hereto.
In the accompanying drawings, which illustrate one embodiment of the invention, Figure 1 is a perspective view of the ejector. Fig. 2 is a central longitudinal section thereof showing the plunger at the end of its ning of the e ecting stroke.

closed position. Fig. 3 is a similar View showing the valve held open by the plunger to, permit a charge to pass'trom the reservoir barrel to the measuring or charge bar.- rel. Fig. at is a longitudinal sectional view showin the .plunger or piston at the begin- Fig. 5 is a per-. spective view of the valve removed.
Similar reference characters are employed to designate corresponding parts throughout the views.
Referring to the drawings, A designates the casing or reservoir barrel which is pret erably of circular cross-section and rounded at its extremities so that it can be inserted into position comfortably, several inches in length and about threequarters of an inch in diameter. The end of the barrel opposite from therounded end has an external thread- 1 for receiving a cap 2 which has, oppositely-extending arms or lugs 3 to be gripped while using the device, the cap having a central tubular guide 4: through which the plunger rod 5 slides, there being on the outer end of the raid a ring-shaped head (3 that forms a grip into which a linger may be inserted for nanipulating the plunger.
Arranged within the rounded end of the barrel A, and disposed axially thereof, is a charge or measuring barrel '1 in which reciprocates the plunger or piston head 8 formed on the end of the rod 5 opposite from the finger ring grip 6. At the inner end of the charge barrel 7 is a frusto-conical mouth 9 which forms a seat for an annular cut-oti' valve 10 through which the rod 5 freely slides, there being between the valve 10 and cap 2 a helical spring 11 that encircles the rod 5 and 0p crates to normally hold the valve ltl seated. \Vheir the valve is seated, powder cannot pass from the reservoir chamber 12 to the charge barrel 7, because the valve engages the sea 9 and the fit between the plunger rod 5 and valve is sufliciently tight to prevent the escape of powder. Whenit is desired to permit a charge of powder to pass into the barrel. 7, the plunger rod is pulled the barrel being interposed against the tension of the spring 11 a sufficient distance to cause the head 8 to engage the valve and move it open, say to the position shown in Fig. 3 from that shown in Fig. 2. With one finger placed over the discharge end of the barrel 7 during this movement, the powder passes into the bar rel 7 and fills the same. \Vhen the outward pull on the rod 5 is released, the spring ll will cause the valve 10 to seat and to move the plunger head 8 into the inner end of the measuring or charge barrel, as shown in Fignet. The device can now. be inserted in the vaginal canal to the proper position, and by a forceful inward pressure on the rod 5, the contents of the charge barrel 7 will be ejected upon the diseased organ.
on the cap 2 and thereby prevent the plunger 8 from moving out of the discharge end of the barrel '7 and cause injury to the organ being treated.
In fillingthe device, 'first unscrew and remove the top piece or cap, without remov-' ing the piston; then place the finger over the opening in the end to prevent possible loss oi powder and fill with the powder intended for use; screw down the cap, pointingthe instrument downward and with the finger still pressing over opening at end, pull the piston back until it strikes the valve, thenby pulling slightly against the spring the powdered contents of the reservoir barrel are permitted to pass down and fill the small charge barrel at the end, the spring then being released and the instrument ready -for use. As the powder chamber or resermethod -operator,-or, if desired, the instrument may voir barrel will hold five or 'six charges of powder, the operation may be repeated so many times without reloading the instrument. Another method of filling the device with powder is to hold same with open end upward, insert free finger in ring'and pull piston downward against spring until powder poured in opening at end will descend through small charge barrel into large chamber bBlOWJ When full it may be prepared for use as before directed. Either may be 'used atthe option of the be used whether full or empty by holding the instrument in one hand, raising the piston by index finger in ring, and dipping into box or otherrecept-acle holding powder until pressing the piston small chamber.is full. Thus it is readily seen that there are three methods of preparing the device for use, all of which are equally efiicient.
When ready for use and the patient placed upon her back, the instrument is inserted into the vagina the proper distance and by downward until ring at end strikes the cap, where-desired and the instrument ist-hen withdrawn. If, however, it is desired to ap- The grip ring 6 is adapted to strike the tubular guide the powder is depositedv l ply more medicine than the small charge 1 barrel will hold, the proper amountshould be placed in the instrument asbefore directed, and the patient still lying down and with the hips raised by inserting pillows thereunder, the instrument is inserted and the operator can, by simple manipulation, eject one measured charge or the entire contents of the larger chamber. Thus it is seen that any quantity of medicine up to the full capacity of the instrument can be injected into the body without removing the instru- ,ment. When it is desired to inject more than one charge, only the exact amount it is desired to use should be placed in the instrument.
From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while we have described the principle of operation of the invention, together with the apparatus which we now consider to be the best embodiment thereof we desire to have it understood that the apparatus shown is merely-illustrative, and that such changes may be made when desired as are within the scope of the claims appended hereto.
Having thus described the invention, what we claim, is:
