' APPLICATOR Filed June 24, 1955 Patented July 13, 1937 NT OFFICE APPLICATOR Myron 0. Shirley, Hollywood, Calif. Application June 24, 1935,'Serial No. 28,193 4 Claims. (o1; 128 234) This invention is an applicator whereby medicinesin the form .of pellets may be applied to the cavities and channels of the human body without requiring the services of a physician or surgeon and without inflicting pain or possible injury upon the patient. It is an object of the invention to provide an applicator of very simple and inexpensive construction and which will be so constructed that at each operation a single pellet will be deposited in the cavity and held by the tissues lining the same whereby the medicine will be applied directly to the diseased parts. The invention is illustrated in the accompanying drawing and will be hereinafter first fully described and then more particularly defined in the appended claims.

In the drawing:

Figure 1 is a longitudinal section of an applicator embodying the present invention.

Figure 21s a transverse section on the line 2-2 of Figure 1.

Figure 3 is a transverse section on the line 3-3 of Figure 1.

In carrying out the invention, there is provided a tubular shell consisting of a forward tube I and a rear tube 2, the forward tube being tapered in its forward portion, as shown at 3, whereby it may readily pass the mouth of the cavity without inflicting any pain. This forward tube l is externally threaded at its rear end to engage internal threads at the forward end of the rear tube 2 whereby the two tubes will be firmly united but may be readily separated when cleaning or reloading of the tube is desired. The rear tube is provided near its front end with an internal flange 4 and a nut 5 is fitted in the end of the tube in advance of said flange and is clamped firmly against the flange by the end of the tube I and held against rotation by a screw 5, as will be readily understood upon reference to Figure 1. The nut 5 has a coarse thread and a corresponding threaded rod or plunger 6 is engaged through the nut and may have a piston or plunger head 1 swiveled upon its forward end or have its forward end portion extended to form a head integral with the plunger. Within the front tube l is an inner tube 8, the inner diameter of which is such that pellets, indicated at 9, may be held therein but will be free to move along the inner tube when force is applied thereto through the plunger 6 and the plunger head 1. The inner tube preferably constitutes the container or cartridge in which the pellets are packed by the manufacturer and will be discarded when a new tube of pellets is to be inserted. The front end at IU, so that as a pellet is forced through the open end of the tube it will be partly crushed and will, therefore, more readily dissolve when it is deposited upon the tissue to which it is applied. The threaded plunger rod 6 is provided at its rear end with a head or flange II which is'preferably integral with the rod and is provided with diametrically opposite openings I2 therethrough spaced apart a greater distance than the diameter of the rod. A knob or 'disc I3 is provided at the rear end of the rear tube 2 and has secured therein diametrically opposite rods M which pass through the openings l2 in the flange II and are properly proportioned to permit said flange to slide readily along the rods. The tube 2 is provided adjacent its rear end with a socket l5 formed by providing an opening in the side wall of the tube, and a ball or globe I6 is adapted to seat in said socket but can not pass outwardly entirely through the opening as the diameter of the opening is less than the greatest diameter of the ball. The ball or globe I6 bears against one end of a helical spring I1 mounted in a pocket I8 extending diametrically of the shank of the knob l3 from a side thereof and as the spring is compressed when the shank of the knob is forced into the rear end portion of the tube 2, it will urge the ball outwardly into position to engage in the seat l5 and yieldably resist turning of the knob. .A set screw l9 carried by the tube 2 and engaged in a circumferentially extending groove in the shank of the knob prevents the knob from slipping rearwardly out of its proper position but when the screw is removed the knob and rods I4 can be withdrawn and thoroughly cleaned and sterilized.

The device is intended to contain thirty tablets and the screw threads on the plunger rod and in the nut will have such a pitch that one complete turn of the knob I3 will feed one pellet through the inner tube. It will thus be seen that the pellets may be fed successively by repeated turns of the knob until the supply is exhausted. The front tube I may then be rotated so that it may ride out upon its threaded connection with the rear tube and access thereby gained to the rear end of the front tube I. The empty cartridges can then be withdrawn, a filled one set in place, and the parts returned to their operative relation, shown in Figure 1. When the knob 13 is turned, the ball [6 will ride out of the socket l5, and when the knob has been given a complete turn, the ball will again seat in the socket where it will lock the knob against moveof the inner tube is slightly contracted, as shown .1. An applicator .a' magazine for pellets in the forward portion ment unless sufficient force is supplied to overcome the resilient frictional engagement of the ball in the socket. When the ball springs into engagement with the socket, a clicking sound will be heard so that the operator will know that the pellet has been discharged and may then withdraw the instrument without further turning of the knob. As the knob is turned, the rods M will, of course, be turned therewith and will impart rotation to the flange H and the plunger so that the plunger will, by its engagement with the nut 5, be fed forward to discharge the pellet. When all of the pellets have been discharged, the knob is turned in the reverse direction so as to withdraw the plunger to its initial position.

It will be readily noted that I have provided a very simple structure which may be easily manipulated and will not require expert service. Having thus described the invention, what is claimed as new is:

comprising a tubular shell,

of the shell, a nut secured in the shell at the rear of the magazine, a plunger fitted in the magazine, a plunger rod threaded through the nut and swiveled to the plunger, a flange at the rear end .of the plunger rod, a rotatable handle at the rear end of the shell, and turning pins carried by said handle and fitted slidably through the flange on the plunger rod.

2. d An applicator comprising a tubular shell, a magazine for pellets in the forward portion of the shell, a nut secured in the shell at the rear of the magazine, a plunger fitted in the magazine, a plunger rod threaded through the nut and swiveled to the plunger, a flange at the rear end of the plunger rod, a rotatable handle at the rear end of the shell, turning pins carried by said handle and fitted slidably through the flange on the plunger rod, the shell being provided with an internal socket near its rear end, and a resilient detent secured to the handle within the shell and adapted to seat in said socket to releasably hold the handle against turning in the shell.

3. An applicator comprising, a tubular shell, a nut secured in the shelLa plunger rod threaded through the nut and having a flange at its rear end, an actuating member rotatably mounted at the rear end of said shell, and turning pins carried by said actuating member and extending from the inner end thereof longitudinally in the shell and slidably engaged through the flange of the plunger rod. I

4. An applicator comprising a tubular shell open at its front end, a nut secured in the shell, a plunger, a plunger rod threaded through the nut and having its front end swiveled to said plunger, a flange at the rearend of the plunger rod formed with openings, arotatable actuating member at the rear end of the shell, turning pins carried by said actuating member and extending from the inner end thereof longitudinally in the shell and slidablyengaged through the openings of said flange, said shell being provided with an internal socket adjacent its rear end, and a resilient detent carried by said turning member within the shell and adapted to seat in said socket to releasably hold the actuating member against turning in the shell. g .1
