To all whom/2'6 may concern:

Beit known-that we, HANs SToPLE and Jnnins N 0 1 subjects. of the Queen of the Netherlands, and residing at Utrecht, N etherlands, have invented a certain new and useful I proved Compression Apparatus f r Stirr ng l e C rc t n D n Qperations and; Bleedings from Wounds, of

.which the following is a specification; I

This invention, relates to improvements in The object of the invention is to provide an instrument of this character which is so constructed that painful pressure on parts of the body adjacent the wound to'which the instrument is applied will be avoided and-which avoids the necessity of using a pad,*the use of which is considered dangerous. v

With this and other objects in View, the invention consists of certain novel features of construction, combination and arrangement of. parts as will, be more'fullygda scribed and claimed. In the accompanying drawings Figure 1 represents an end view of this instrument; Fig. 2 is a longitudinal section thereof; Fig. 3 is a transverse section of this instrument showing it applied.

In the embodiment illustrated this im -proved instrument comprises a' cylindrical casing or drum is having a spool-shaped member mounted therein with the two end disks a and a connected by a broad band 6, and its spindle c disposed centrally between the two disks and revolubly mounted in said disks. This spindle projects at one end beyond the end of the casing 70 and is provided at said projecting end with an operating handle d. On the other end of this spindle which projects beyond the disk (1 is mounted a fine toothed ratchet wheel 6'.

A spring pressed pawl f is mounted on the outer face of the disk a with its tooth positioned forengagement with the teeth of the ratchet wheel 6 andwhich is yieldably held in engagement with said ratchet teeth by means of a curved spring 7 here shown made integral with the free end of the pawl f. A press button 9 has a shank which extends through an aperture 76 in the casing '70 and is connected with the free end of the spring f as shown in Fig; I and is designed when pressure is exerted thereon, to press said spring and force the pawl out of engagement with the teeth of the ratchet wheel and the handle is turned to wind up the tape e thereby .releasing thespindle c and': perl ti g t 'b rned e y int er directlon by'ineansof the handle 01., Another a nte se =2e 19 springqf is also positioned to enga-ge-the pawl [to hold it in yieldable engagement with the ratchet e. (SeeFig. 1a)

A slide Yfiismountedonthe shank of the button g outside the casing 70v and operates to secure said button in position. .;.A tape. is secured at one end to the spindle a and is adapted; to be wound thereon, the free end thereof projectinginorimally through a slot 70 in'the side wall of the casing 70. (See Fig.3.) The freeend of this tape it has an' inturned hook. ,-Z1

which. is designed to engage an outt-urnedfl."

hook i seciilted'to the. free end of ata'pe i, the .othervel d of which .is fixed, within .the

casing: 71 }in;: any suitable m'anner.- Se.e 75

Whenthefre'e ends of the two; tapes. are

interlockingly engaged by means of their cooperating hooksh "andxz' -they form a loop h the size of which. may be varied by.

winding or unwinding the tape it on the spindle c and which is held in adjusted position by the locking pawl f when engaged with the ratchet e.

In the use of this instrument, the tape A is drawn out of the casing Zea suitable distance to permit it to be passed around the member to which the instrument is to be applied, the spindle having first been released by exerting the pressure on the button 9. After said tape has been passed around the member to which the instrument is to'be applied, the hook at the free end thereof is engaged with the cooperating hook 2" on the fixed tape 71 on the spindle 0, the pawl f riding freely over the ratchet teeth of the wheel 6 during. such turning and when the proper tension has been attained, the pawl will engage the teeth of said ratchet. wheel and hold the spindle against backward or unwinding movement, thereby reliably securing the tape around the member to which the'instrument is applied. By constructingthe casing la in cylindrical form and housing all of the operating parts therein, a smooth surface is brought to bear on the body of the patient and consequently, painful pressure on adjacent parts is avoided. By so constructing this tourniquet, a uniform pressure is exerted and circulation'of the blood through the arteries is impeded and finally stopped Without the use of a pad, and by dispensing with this pad, the instrument may beapplied at any desired height above the wound.

By providing the peculiar locking mechanism described above the compressor will operate even should the spring f fail to act.

I claim as my invention:

1. In a tourniquet, a cylindrical casing having a slot in its side wall, a spool-shaped member revolubly mounted therein, a tape Wound on. said spindle with one end extending through the slot in said casing, a stationary tape disposed in said casing and having one end extending through said slot, the free ends of said tapes having cooperating fastening elements, means for locking said spool against turning in one direction, and a push button having a head outside of said casing for releasing said locking means.

2. In a tourniquet, a cylindrical casing having a slot in its side wall, a spool-shaped member revolubly mounted therein, a tape wound on said spindle with one end extending through the slot in said casing, a stationary tape disposed in said casing and having one end extending through said slot, the free ends of said tapes having cooperating fastening elements, means for locking said spool against turning in one direction, a push button having a head outside'of said copies of this patent may be obtained for casing for releasing said locking means, and

7 means for securing said button in looking position. v

3. In a tourniquet, a cylindrical casing, a spindle revolubly mounted therein and pro vided with disks at its opposite ends, said spindle being loosely mounted in said disks and projecting at its opposite ends beyond the outer facing thereof, a handle on the outer end of said spindle, a ratchet Wheel secured to the inner end thereof beyond the inner disk, a spring-pressed pawl positioned to engage said ratchet wheel, a pawl-releasing button connected with the spring thereof and having its head disposed outside said casing, a tape fixed atone end to said spindle and having its other end extending through a slot in said casing, and a tape fixed at one end in said casing with its other end extend- 1 1 ing through the slot in the casing, the free ends of said tapes being provided with co operating fastening elements.

In testimony whereof we afiixour signatures in presence of two. witnesses.
