SURGICAL-LIGATU RE RECEPTACLE.

SPECIFICATION forming part of Letters Patent No. 443,812, dated December 30, 1890.

Applicationfiled October 9, 1890- Seriel No. 367,512. (No model.)

To all whom it may concern:

]3e it known that I, OLIVER P. BARBER, a citizen of the United States, residing at Sagi: naw, in the county of Saginaw and State of Michigan, have invented certain new and use ful Improvements in Ligature Carriers and Preservers, of which the following is a specification, reference being had therein to the accompanying drawings.

As is well known,when ligatures of prepared silk or catgut or other material used by surgeons are to be retained anylength of time before using the same they should be preserved in'a suitable antiseptic fluid in an air-tight vessel, in order to prevent the deposit thereon of germs or septic substances of a nature highly injurious to wounds, in the treatment of which such ligatures are employed; and it is the object of this invention to provide a simple, durable, and comparatively inexpenslve device forconveniently packingor storing ligatures, which may be carried on the person without exposing the same to any liability of contact with deleterious substances of any kind; and it consists, first, in providinga receptacle having an air-tight cover which is rounded out or hollowed on its interior; second, in providing a piston having a perforated head provided with a packing and-adapted to fit within said receptacle; third, in providing spools having double beveled flanges; fourth, in providing the flanges of such spools with notched edges or perforations, and, fifth, in other details of construction and arrangement of parts, as hereinafter described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a vertical longitudinal section through the receptacle and showing the piston and spools in full lines; Fig. 2, a perspective view of the piston, and Fig. 3 a detail perspective of one of the spools.

Similarletters refcrto'similar parts throu ghout the several views.

A represents a cylindrical receptacle, preferably of glass, of the same interior diameter throughout its length, and having its mouth end exteriorly reduced, as at a, to receive a cap or cover B. The cap or cover B is formed, preferably, with a rounded top and the inner sur face of which is hollowed out, as shown in or cover and the offset on the receptacle, in

order to render the same air-tight; or any other desired means of fastening the. cap airtight and securely to the receptacle may be employed, as found most convenient, the only requirement being that the interior of the cap or cover be hollowed out,so as to leave a space between the upper end of the receptacle and the interior top or surface of the cap or cover.

0 represents a cylindrical rod, preferably of glass, which,for convenience sake, is herein termed a piston, on one end of which a handle 1) is formed and on the other end an enlarged head 0, having its inner end beveled, as at c, said head being adaptedin size to enter or fit Within the receptacle A snugly but movably therein. The head 0 is formed with a suitable number of perforations'd, extending lengthwise through the head, and on the periphery of the head a groove 6 is formed, which extends around said head, the piston and its head being molded or pressed from one piece of glass. In the groove 6 asbestus cotton f is packed or wound, so as to completely fill said groove and extend slightly beyond the periphery of the head, the object of which is to cause thepiston to remain in any position relative the length at which it extends beyond the mouth of the receptacle, at

which it may be placed in the receptacle or drawn therefrom through the frictional hold of the asbestus on the interior of the receptacle. D represents the spools on which the silk or catgut is wound, said spools having their ends and their flanges g beveled off on both sides and the edges notched, as at h; or, if preferred, perforations 71/ may be formed through the flanges, as shown in Fig. 3. p

The spools after having been wound with the ligatures are slipped onto the piston over its handle end, the first one resting on the beveled edge or end of the head 0 andthe others resting one on the other, as shown in- Fig. 1, so that they may be easily andreadily rotated on the piston independently of each other and without undue friction between the spools. The receptacle being previously filled with a suitable antiseptic fluid, the piston and its spools are inserted therein, or the piston may be inserted before the fluid, and the latter, poured in afterward, finds its way through the notches or perforations, Whichever are used, down into the receptacle and through the perforations in the headto the bottom of said receptacle. The piston, being of a greater length than the interior of the receptacle, projects beyond the same and its handle lies in the hollowed-out cap or cover, so that upon removal of the cap the handle may be grasped without the hand coming in contact with the liquid and the piston drawn out of the receptacle the desired height to give access to the spool or spools desired and the ligature unwound therefrom as needed, the piston remaining at the height to which it is drawn by means of its frictional contact with the receptacle through the packing on {its head. The notches or perforations in the spool-flanges, which are of the same diameter as the head (2, permit the liquid in the receptacle to escape back into the receptacle when the piston is withdrawn either partially or wholly therefrom, as do the perforations in the head.

Having thus described my invention, whatl claim as new, and desire to secure by Letters Patent, is

1. In a ligature carrier and preserver, the combination, with a receptacle having an airtight cover, of a piston, the spools mounted on said piston, and means for sustaining said piston at any desired height in said receptacle, substantially as described.

2. The combination, in a ligature carrier and preserver, of the receptacle, a piston having an enlarged head, asbest'us cotton secured to said head,and spools mounted on said piston, substantially as described.

8. The combination, in a ligature carrier and preserver, with a cylindrical receptacle having an air-tight cap or cover, of a piston having an enlarged head adapted to permit the passage of liquids therethrough, and the inner or upper end of which is beveled, and, the spools having beveled ends and flanges adapted to permit the passage of liquids, substantially as described.

In testimony whereof I atiix my signatu re in presence of two witnesses.

OLIVER 1. BARBER.
