UNITED STATES PATENT OFFICE JOSEF LEITER, OF VIENNA, AUSTRIA.

IMPROVEMENT IN HYPODERMIC SVRINGES.

Specification forming part of Letters Patent No. 159,192, dated January-26, 1875; application tiled January 12, 1875.

To all whom it may concern:

Be it known that I, JOSEF LETTER, of Vienna, Austria, have invented a certain new and Improved Hypodermic Syringe, of which the following is a specification:

This invention is illustrated in the accompanying drawing, in which- Figure 1 represents a longitudinal section. Fig. 3 is a cross-section in the line x Fig. 1.

Similar letters indicate corresponding parts.

This invention consists in an apparatusfor a painless subcutaneous injection in the cellular tissue of the human skin,` and is composed of a cylindrical tube, inside of which a small sliding syringe is arranged, with a mouthpiece or spout forming a sharp-pointed needle or lancet.

The piston of said syringe is operated by a sliding head, npon which acts a spring, which, it' the head is drawn back and then released, forces said head with rapidity against the piston ot' the syringe, and, at the same time, the syringe is pushed forward, and the lancetshaped spout enters the cellular tissue of the skin, where the contents are injected.

This operation is performed with great rapidity, in preference of the slow, painful, and

uncertain proceedings as heretofore done by the hand of the physician.

In the drawing, the letter a designatesa cylindrical tube, inside of which are situated' a spiral spring, b, and a slide or head,c. A second tube, d,--is screwed to the tube a., and over this tube is fitted a sleeve? the outer end ot which forms a cone, fr, to allowthe lancetshaped spout g of the syringe e to pass through, and to enter that part of thehuman body against which the apparatus is held in an inclined direction, the inclination bein gfdetermined by the tapering end of the sleeve f.

The tube d, which contains the syringe e, is provided with a shoulder, l, to stop the for; ward motion of the syringe. The rod o of one ot' these recesses the sliding head c is held in position.

In operating my apparatus, the syringe is first filled with the liquid to be injected; thon the sliding head cis drawn back and locked by the trigger h and one of the recesses k, and the apparatus is placed in the desired position o`n the human body, and the slide c is released bytouching the trigger h, so as to force the syringe forward to the end ot' the tube d, and, since the syringe is stopped in its forward movement 'by the shoulder l in said tube, the piston is pressed into -the barrel of the syringe, and the liquid is ejected.

Y To regulate the quantity ot' liquid to be injected, the syringe may be partially lled, or, if several injections are to be made out of one filling, the piston-rod, which may be divided in proportional parts, is set to a certain division by its regulating-screw to stop the action of the syringe at the required spot.

The tapering end, T, of the sleeve f forms the base of the apparatus during its operation. Said sleeve can also be adjusted to control the depth to which the lancet g enters the skin.

The tube d is provided with a scale, so as to be able to regulate the position of the sleeve f.

The operation of my apparatus, being exceedingly rapid and automatic, is entirely free from pain. It can be regulated with exactness, and it is free. from all danger.

. What I cla-im as new, and desire to secure by Letters Patent, is.- i

1. The combination of a regulating-sleeve, f, with a syringe, c, provided with a lancetshaped spout, g, substantially as described.

2. The regulating-screwm, in combination withl the syringe e, tube d, and regulating sleeve f, substantially as set forth.

` 3. The combination of a head orjhammer, c, and trigger h with a syringe, e, and guidetube d, substantially as described.

In testimony that I. claim the foregoing I have hereunto set my hand this 2d day of December, 1874.

V JOSEF LEITER. Witnesses:
