BINDING APPLIANCE.

To all whom it may concern: c

Be it known that I, ELLERY POLLARD, a citizen of the United States, residing at the borough of Brooklyn, in the county of Kings and State of New York, have invented anew and useful Improvementin Binding Appliances, of which the following is a specifica- 7 tion.

This invention relates to releasable binding devices such for example as the tourn1 quet where the; ChQTZLCtQI'IStlC OI qulck ap plication is a prime requisite, where security the strand is drawn from. its free end, to"

tighten the appliance 1 about the object, the strand is caught-between the stop and the ring, whose inner peripheral edge bites into the strand at that point and thus securely holds it in a binding taut state. The binding device is however easily releasable simply by lifting the stop, which mayhave the form of a handle capable of being grasped between the finger and thumb, this act having the effect of separating-the stop from the ring and leaving the strand free to run through the ring. r

Other features and advantages of my said invention will hereinafter appear.

In the drawing Figure 1 is a group of diagrams, repre senting the progressive stages in the operation of forming the stop knot.

Fig. 2 is a view of the appliance.

Fig. 3 is an enlarged, sectional view of a portion of the appliance, showing the stop knot, and the co-action therewith of the gripping ring.

Fig. 4 is an elevation, showing the appliance employed as a tourniquet, with the pad pressed against an artery in a human wrist,

' and Fig. 5 is an end elevation of the same.

While serviceable for various purposes, I have in this application illustrated myimproved binding appliance in the form of a Application'fil ed March 13, 1919. Serial No 282,325.

Specification of Letters Patent. g 29, 1920.

tourniquet, whoseJusefor first aid, to pre ventloss of blood, mustbe efficient, capable of instantaneous employment, and always available. Therefore my improved appliance is so devisedthat it can be sold for a trifle and carried all as a sary pocket contents. I

In the figures the device is seen to comprise a'flexiblestrand 1, which may be a piece of fish+line or whipcord, o f fine quality, to ben'on-fraying and durable.

part of necesmay consistxof a knot formed in the strand.

,As an example of a desirable form ofsuch knot, possessingthe desired qualifications, it is produced as shown in the progressive diagrams of Fig. 1. Thus, as in diagram a, the strand 'is first doubled to form a loop.

Near: one end of the strand, which is of suitable length,'it is provided with a stop 382, which Then, as in diagram 6, the-short end a of the strand has been turned about the root of the loop to form a first coil 6 while in diagram 0 said-short end has been wound several times at the loop side of coil 6 to form the succeedingcoils 0 In diagram (Z the-next stageshows the shortend as passed through the loop, wh'ere it is to be'grasped, while the long end of the strand isldrawn} upon to contract the loop upon the outer surface of coils 0 in which act the short end of the strand becomes caughtbetween said loop and coils, as shown'indiagram c, leaving a substantially flat surface at e for the inner portion of thecoils. [The stop 2 is thus constituted as an integral fabrication of the strand 1, andatv its surface 6 provides a seat forafring or'eyelet 3 that'jis threaded loosely upon said strand, the orifice in said ring or eyelet being large enough to receive.

said strandin double ply. Thus, for service the stop 2- and the free end of the strand project at one side of the ring or eyelet, and a contractible and extensible loop 5 formed from the strand extends at the otherside of the loop. The ring or eyelet 3 is given a becomes locked in its binding relation to an object, this effect being achieved instead through the correlated efforts of several factors. In applying the device to bind an object, as 6, the loop 5 isplaced thereover and then the free end of the strand is drawn through the ring or eyelet until jsaid loop 5 tautly binds upon said-object. binding causes the surface of the object to press outwardly upon the strand, which urges the ring. or eyelet to press a portion of the strand between it and the seat 6 whereby the frictional or burred inner edge of the ring or eyelet bites into that portion of the strand, the grip thus effected becoming the more secure according to the degree of ten sion created by the tautness of the binding action. It will also be appreciated that the flexible character of the cord used for the strand 1, and of which material the seat 6 is composed, assists,'by co-action with the ring or eyelet, through the embedment thus offered, in increasing the efficiency of the gripping factors.

'For tourniquet practice a pad member, as 7, may be carried by the strand within the, loop portion 5 thereof, in order that said member may be placedupon an artery to exert pressure thereon in stopping the flow of blood. Or, obviously, any other desirable form of. pad, either connected With or separate from the appliance, may be employed in conjunction therewith.

In somecases the appliance may be used without a pad, as for instance where it is employed simply as a securing band or girdle. a

' I claim i 1. A binding appliance consisting of a flexible strand, a fixed stop thereon, and a fiat ring to receive said strand, doubled, withsaid strand forming a contractible loop, said stop. having a substantially flat surface to co-act with said ringin gripping the strand as tightened about an object, to

secure the appliance against loosening.

This taut 2. A binding appliance comprising a flexible strand havinga knotformed near one end thereof, and a flat ring loosely fitted on said strand, said ring adapted to also receive a double ply of said strand in V the formation of a girdling loop, and the inner surface of said knot, opposed to said ring, having a substantially fiat formation for the purpose of frictionally gripping saidstrand between saidknot and ring when the loop is tightened about an 'engirdled object.

3. A binding appliance comprising a flexible strand having a knot formed near one end thereof, the inner surface of said knot'being of substantially flatformation, and a flat ring slidable on said strand, doubled, leaving a contractible loop in the strand, the inner peripheraledge of said ring having one-way acting frictional engaging means which co-act with the opposed surfaces of said knot and ring to effect tractible loop, a pad c'arriedby'said loop,

and a knot near one end of said'strand, said knot having a substantially flat engaging surface to co-act with said ring in gripping the manipulable portion of said strand,

when drawn tautly about an object, and

said knot also serving as a releasing member. a

In testimony whereof, I havev signed my name to this specification in the presence of two subscribing witnesses, this7th day of March, 1919."
