BLOATI'NG NEEDLE.

No. 387,480. Patented Aug. 7, 1888.

UNITED STATES PATENT ()FFICE.

JOSEPH J. ALLEMAN, OF UNION SPRINGS, NEW YORK.

BLOATlNG-NEEDLE.

SPECIFICATION forming part of Letters Patent No. 387,480, dated August 7, 1888.

Application filed August 26, 1886. Serial No. 211,887. (No model.)

To aZZ whom it may concern.-

1 to show the internal construction; and Fig. 2,

a transverse sectional view of the same on line was of Fig. 1, the inner tube being turned so as to open the hole in the needle.

Letters of like name and kind refer to like parts in each of the figures.

The object of my invention is to provide an improved bloating-needle for drawing off liquids and gases from cavities or swellings in animals with the least possible amount of puncturing of the flesh and without cutting or tearing the same; and to this end my invention consists in the needle and in the construction, arrangement, and combination of the parts thereof, as hereinafter specified.

In the drawings, A designates the shank of the needle, which is preferably made slightly tapering, as shown. This shank is hollow, having the central bore, B, open at its upper end and closed at its lower. The lower end of the shank is provided with a sharp conical puncturing-point, A, which I call a pencilpoint, as distinguished from a lance one. The latter would cut and tear the flesh, while the pencil-point does not, but simply presses aside the fibers of the flesh through which the needle is forced when in use. Near this point is the opening 0 through the wall of the shank communicating with the bore B. Upon the upper end of the shank, and made in one piece therewith or attached thereto, is the annular plate 1), forming a head for the needle. Within the tubular shank A is a correspondingly-shaped concentric tube, E, having its lower end, 6, below the opening 0 in the needleshank, and its upper end, projecting above such shank, provided with a head, F, like that on the shank. This inner tube is near its lower end provided with an opening, G, adapted to be brought into or out of coincidence with opening 0 as the tube is turned within the needle-shank to open or close the latter opening. Below' the head D there is a slot in the needle-shank, and in such slot plays the stop-pin H on the tube E. The pin playing thus in the slot serves to maintain the tube E in proper longitudinal position within the needle-shank, and also to limit the turning of the tube to properly open and close opening G. The pin will then, by its position in the slot, indicate when the tube is turned to bring the opening G therein into or out of coincidence with said opening 0.

Other means for properly limiting the rotation of the tube and indicating the amount of such rotation within the shank can be provided without departure from my invention; but I prefer the means shown and described.

The pin can be a screw one or be fixed or removably attached to the tube.

The operation of my needle, constructed as described and illustrated, is as follows: The tube E having been turned to close the opening 0 in the shank, the needle is, by pressing on head D or F, thrust through the flesh of the animal to be treated until its point penetrates the liquid or gas containing cavity. None of such liquid or gas will yet escape through the needle. The tube E is then turned to bring the opening G into coincidence with opening 0, when the gas or liquid will pass freely in through such openings and out through the tube.

It will be observed that the inner tube is not withdrawn or separated from the needle-shank, as in the case where a rod is used to stop the bore of the needle while thelatter is being thrust into the flesh. Such rod must be withdrawn to allow the liquid or gas to flow out.

All that is necessary to start the flow where my needle is used is to give thetube E a slight turn. There is no separate piece to be withdrawn and replaced, and which is liable to be mislaid.

The advantage of a pencil-point on the needle, instead of a lance-point,is, as indicated hereinbefore, that the former as it penetrates the flesh merely pushes the fibers aside, and does not cut or tear its way in.

Having thus described my invention, what I claim is- 1. In abloating-needle,in combination with the hollow shank closed at its lower end provided with a puncturing-point and having an opening in its side, the tube within such shank 5 having an opening adapted to be broughtinto and out of coincidence with the opening in the shank side by turning the tube, substantially as and for the purpose set forth.

2. In a bloating-needle,in combination with IO the tubular shank having the puncturingpoint and the opening in its side, the tube within the shank having the opening in its side, and means, substantially as described, for limiting the rotation of the tube Within the 15 shank, substantially as and for the purpose described.

3. In combination with the tubular shank having the puncturing-point, the opening 0, and the slot h, extending in a plane at right angles to the axis of the shank, the tube within 20 the shank having the opening G, and the pin on the tube engaging the slot in the shank, so as to prevent longitudinal movement of the tube within the shank, as well as limit its rotation in the latter, substantially as and for 25 the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this 14th day of August, A. D. 1886.
