POWDER-PLACING SYRIN Application filed July 16,

My invention relates more particularly to an improved and simplified syringe for discharging powder and the like into cavities, and it has at its main object'to provide a syringe bulb and tube adaptedto have in- I sorted therein, or connectcdtherewith a capsule or the like containing a predetermined amount of the powder or matter to be discharged into the cavity, whereby it is possible to prepare the powder in the form of loaded capsules which can be quickly and readily put into place in the syringe and inserted into the cavity for discharge by the comprescaps have been removed, and indicating in light broken lines the removal of said end caps and the placement of the capsule body upon the end of said tube;

Figure 3 is aside elevation of the removamable sleeve or nozzle which is placed over the capsule body after the latter has been placed on the end of the tube; and

Figure 4; is a view showing a slightly modified form of the invention, and in which a spring collar is used to lock the capsule in place on the end of the tube, instead of using the sleeve shown in Fig. 3.

Referring now more in detail to the drawings, my invention as here illustrated, comprises a syringe tube or body 5, with a bulb 6, for furnishin a blast of air, the end of the tube or body 5, being provided with a collar or abutment flange 5, and a small stud 7, the outermost end of said tube being further reduced, as at 5, to receive the end of a capsule body, designated 8, and indicated in light broken lines in Fig. 2, and in section in Fig. 1. Said capsule body may be of any suitable material and provided with caps, 9, 9, or other closure means which can be removed in order to place the capsule over the end 5 of the syringe tube 5, as indicated. Said capsules can be provided in quantity and loaded with the desired powder or other medicinal matter to be used with ,a syringe and used as needed. A sleeve or nozzle member 10, is provided to 1927'. Serial No. 206,3245

telescope over the capsule body after it. has

been placed upon the end of the tube 5, said sleeve or nozzle having a bayonet slot, 11, by

means of which it'interlocks' with the stud 7,

as shown, for the purpose of securing the capsule 1n place. The outer end of said sleeve or nozzle 10, is provided with a slightly reduced outlet or discharge opening, 10, forming an abutment shoulder 10, for the outer end of the capsule, as clearly illustrated in the sectlonal view, Fig. 1.

A capsule body ma? be provided which can be used without the s eeve or nozzle, as designated at 12, Fig. 4, and I have provided a sprlng collar, 13, having a, bayonet slot, 14,- to interlock with the stud 7, said spring collar having the spring fingers 13, adapted to yieldingly hold the capsule as said collar is put into place over. the body of the capsule and interlocked with the end of the syringe tube, as clearly illustrated in Fig. 4.

Thus I have provided a very simple, practlcal and economical syringe device for use with preloaded capsules for discharging a given amount of powder or other medicinal matter in dr form into a cavity which can only be reac ed by the insertion of a tube or nozzle of some kind, and while I have lllustrated my invention for descriptive purposes, I do not limit it to the details of construction and arrangement shown, except as I maybe limited by the hereto appended claims.

I claim I u i I I 1 In 'comblnatlon, asyringe body or tube adapted to receive a capsule, a capsule adapted to fit telescopically the endof said tube, and detachable means for securing said capsule in place on said tube with both ends open,

and means forming apart of said syringe for forcing a blast of air through said tube and said capsule for discharging the contents of said capsule.

2. In combination, a syringe having a tubu- 1 0 lar part adapted to receive in telescoping relationship therewith a capsule, a capsule preloaded with matter and adapted to have its ends opened and connected with said tubular part, and means fitt ng over said capsule and 3. In combination, a'syri'nge tube for insertion into a cavity, a capsule adapted to be telescopically connected with the end of said tube, said capsule being adapted to contain matter to be discharged therefrom by a blast from said syringe tube. means forming :1 part of said syringe for creating a blast of air through said. tube and said capsule, and a. member udupted to telescope over said capsule and to interlock with said tube for bolding so id capsule in place.

4. In combination :1 svringe having: a part adapted to receive and hold :1 capsule like element containing matter a preloaded capsule adapted to be connected therewith in such relationship that. be. operation of the syringe discharges the contents from said capsule, and means telescoping thereover for holding the capsule like element in place. on said syringe part whereby said capsule can be inserted into a cavity for discharging its contents therein by the operation of said syringe.

5. A syringe of the character referred to including in combination a. bulb. a tube having a reduced portion to receive thereover a capsule body, a capsule body adapted to be telescoped with said reduced portion a member adapted to be placed over said capsule body and over said rcduced'portion and interlocked with said tube for holding said capsule body in place, whereby the operation of said syringe bulb forces the contents of sziid eupsule body therefrom, for the purpose described.
