LlGATURE-RECEPTACLE.

SPECIFICATION forming part of Letters Patent No. 554,041, dated February 4, 1896.-

Applioation filed March 18, 1895. Serial No. 542,141. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE M. STRATTON, of Bridgeport, county of Montgomery, State of Pennsylvania, have invented a certain new and useful Improvement in Surgical Ligature- Receptacles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention has relation to certain improvements in the construction of surgical ligature-receptacles, and has for its chief characteristics an independent removable disk provided in the bottom and in the top of the receptacle, each disk being of a diameter preferably approximating the interior diameter of the receptacle and centrally provided with a flanged circular opening for the reception of the opposite ends of the spoolspindle, and tension-disk of elastic material of a diameter slightly greater than the inte rior diameter of the mouth of the receptacle provided immediately above and bearing upon the upper disk adapted to impinge against the inner walls of the mouth of the receptacle to hold the spool-spindle in position in its bearings in the independent'disks and to allow of the adjustment of the upper disk upon the spool-spindle to regulate the tension of the disks upon the spool-spindle and to prevent the too free movement of the spool in its bearings.

In the accompanying drawings, Figure 1 is a sectional elevation of a ligature-receptacle constructed in accordance with my invention. Fig. 2 is a sectional plan view of the same on the line 2 2, Fig. 1; and Fig. 3 is a sectional elevation of a modified form of construction of easing.

Referring to the drawings, A represents an open-mouthed cylindrical vessel formed of glass and provided at its upper end with screw-threads, on which may screw a metallic or other cap B, as of the ordinary construction of ligature-casing, and provided with an inner disk I), of rubber or similar elastic material, which, when the cap is screwed into position, firmly presses against the open mouth of the bottle and prevents all danger from leakage of the antiseptic fluid with which the bottle is filled.

At the base of the bottle and in the upper portion of the bottle are placed the independent removable disks C G, preferably approximating in diameter the interior diameter of the bottle and centrally provided with the flanged circular openings for the reception of the opposite ends of the spool-spindle. The disk C, preferably slightly concaved so that its outer edges only will be in contact with the bottom, is centrally provided, with the upwardly-projecting flanges o integral with the body of the disk, forming a tubular bearing for the spindle end d of the spool D. The

upper disk, G, is alsov provided with upwardly- 6 5 d of the spool D to form a bearing for the same, though if desired this centrally-disposed bearing in the disk G may be constructed in a manner similar to the construction of the tubular flanged bearing 0 of the disk 0, as illustrated by g in dotted lines,

Fig. 1.

The spindle ends at and d are formed integral with the spools E and preferably of a conical form or dome shape, as shown in the drawings, the diameter nearest the spool ends being preferably greater than the greatest diameter of the central bearings in the said disks, while the diameter of the spindle ends at and near the outer ends is preferably less than the diameters of the bearings in the said disks. The object in this construction is to more securely hold the spool between the two independent movable disks and to tend to prevent the same from too freely turning when the desired tension is brought to bear 0 through the medium of the tension-disk. The tension-disk H, formed of rubber or similar material, is of a diameter preferably slightly greater than the interior diameter of the mouth of the receptacle orbottle and pro- 5 vided immediately above and upon the upper face of the upper disk, G. lVhere the dome shaped pocket is employed in the disk G, as shown in the drawings, the tension-disk is provided with a central orifice h to allow of me the reception of the same. The tension-disk H also operates to tightly seal the bottle or receptacle and to prevent any danger of escape of the contents thereof. If the central bearing of the upper disk is constructed similar to that construction shown in the lower disk the tension-disk ll would be formed solid, in which case a slight projection on the top of the disk G would serve to secure the rubber to the disk and prevent any lateral movement of the latter.

As the diameter of the upper disk, G, is nearly equal to the diameter of the tensiondisk, only a small portion of the surface of the latter is exposed to the deteriorating chemical action of the antiseptic fluid, which is a desirable feature. The ligature is preferably passed from the bottle between the outer edge of the tension-disk and the inner surface of the mouth of the bottle.

In my improved construction herein described I am enabled to exert greater or less pressure between the bearing-points of the spindle ends, integral with the spool, and, by increasing or decreasing the frictional resistance to the turning of the spool, to maintain the ligature in a proper position upon the bobbin, it being simply necessary in order to gain this desired result to press the tension disk to a greater or less distance within the mouth of the bottle, the construction of the parts being such, as hercinbefore described, to bring about the desired result. The ligatures when so held will maintain the proper position upon the bobbin or spools, and are not likely to become unwound or loosened, as is the case where the bobbins or spools are permitted to freely rotate on their axes or supports.

In the modified structure illustrated in Fig. 3 the general construction is substantially similar to that hercinbefore described, save that the receptacle is here divided by a transverse partition a into two separate compartments, each having an open mouth closed by a screw-cap and each containing the independent removable disks, tension device, spool and integral spindle of the construction illustrated in Fig. 1.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a ligature-holding casing having open mouth and cap therefor, two independent removable disks provided respectivelyin the top and bottom of said casing having centrallydisposed spindle-bearing, a spool having integral spindle ends provided respectively in the said bearings, and tension-disk provided above and upon the upper disk having its outer edges impinging upon the inner walls of the mouth of the casing, said tension-disk operating to retain the upper bearing-disk in a desired position relatively to the lower disk and for regulating the tension upon the spindle ends of the spools in the manner and for the purpose substantially as described.

2. A ligature-receptacle having an outer casing and removable cap, comprising two independent disks, 0, G, adjusted in the top and bottom of the said casing respectively, having centrally-disposed tubular bearings, spool, D, having integral spindle ends, d, (1 provided in said bearings, tension-disk, ll,

provided upon and above the disk, G, impinging on the inner walls of the mouth of the easing for retaining the disk, G, in position and regulating the tension of the said disk upon the spindles, substantially as described.

3. A ligature-receptacle having an outer casing and removable cap, two independent movable disks, C, G, provided in opposite ends of the said casing respectively, having centrally-disposed tubular bearings for the reception of the spindles of the spool, spool, D, having integral cone shaped spindle ends, (1, (1 provided in said bearings, tension-disk, II, provided upon the disk, G, having its outer edges impinging upon the inner walls of the mouth of the casing, regulating the tension upon the spindle ends, substantially as described.

l. A ligature-receptacle having an outer casing and removable cap, independent mova bio disks, 0, G, provided in opposite ends of the said casing respectively, said disk, 0, having the tubular flanged bearing, 0, and the disk, G, having the dome-shaped pocket-bearing, 5 spool l), integral cone-shaped spindle ends, d, (1*, provided in said bearings, tensiondisk, ll, provided upon the disk, G, having its outer edges impinging upon the inner walls of the mouth of the casing centrally-disposed orifice, it, provided in said tension-disk for the reception of the dome-shaped pocket, g, substantially as described.

In witness whereof I have hereunto set my hand this 8th day of March, A. D. 1895.
