D. B. MARTIN. SYRINGE TUBE SINKER'.
(No Model.)
Patented Mar. 3
UNITED STATES ATENT CFFICE.
DENNIS B. MARTIN, OF NEIV HAVEN, CONNECTICUT.
SYRINGE-TUBE SINKER.
SPECIFICATION forming part of Letters Patent No. 447,574, dated March 3, 1891.
Application filed November 17,1890. Serial No. 371,679. (No model.)
To all whom it may concern: I
Be it known that I, DENNIS B. MARTIN, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Sinkers for Syringe-Tubes; and I do hereby declare the following, when takenin connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact descripthe surface of the fluid which the syringe is to draw, and also to hold the end of the tube distended for the free admission of such fluid. It is desirable to provide these sinkers or the termination for the inlet end of a syringetube with some device by which the syringe as a whole may be suspended from that inlet end, so that when hung up by that end the valves will 0pen,so that the syringe will completely drain. These sinkers at the termination of the inlet end of the syringe-tube have been made from cast metal provided with a book by which to suspend the syringe; but such cast-inetal termination is objectionable because of its inflexibility, and the hook is also objectionable because of its great liability to accidentally catch upon objects.
The object of my invention is to produce a sinker for syringe-tubes which shall be of substantially the same material as the tube itself, and therefore flexible and elastic, and.
a tubular body of a diameter somewhat greater than the internal diameter of the tube to which it is to be attached, and the attaching end is constructed with an annular bead a, so that when the tube B is expanded and drawn over the said bead onto the body of the sinker it will clasp the said body and bead, so as to firmly attach the sinker t0 the tube. The body is provided with an annular enlargement E, which is in the form of a large bead, and so as to make a support for the sinker when lying on the bottom of a vessel, so as to raise the inlet end of the sinker somewhat from the bottom of the vessel. The tubularbody is open from end to end, so as to afiord free entrance through the body-into the tube 13.
At the outer end the body is constructed with a ring-shaped loop F, made of the same material and integral with the body, and
spans the opening into the tube, as seen in Fig. 2. The loop is flexible, so that it may be readily turned away, from over the opening, should occasion require, and its flexibility prevents its accidental engagement with objects interfering with the general use of the syringe, and the loop serves as a most convenient means of hanging the syringe, much less objectionable than the usual rigid hook, because of the less liability of accidental detachment when it is hung.
Another and great advantage of this soft flexible elastic sinker over the hard sinker is in the fact that thesoft sinker avoids the rattling which necessarily follows the contact of the hard-material sinker with the vessel which contains the fluid, the sinker of this invention being noiseless.
I claim The herein-described sinker for syringes, consisting of a tubular body made from elastic flexible india-rnbber adapted, at one end for attachment to the inlet-tube of the syringe, and at its opposite end constructed with a loop made of the same material and integral with the body, substantially as described.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
DENNIS l3. MARTIN. \Vitnesses:
JOHN E. EARLE, FRED O. EARLE.
