PACKAGE it-s v Application filed February Thisinvention aims to provide a simple means whereby a cord of any desired size, used for tying, up a package of letters, or

anything else, may be gripped firmly, to hold tliepackfage, it being possible to release the cordireadily at the will of an operator.

Another object of the inventionis toprovide an article of the class specified which will be simple in constructiomnot likelyto get out of order, and capable of being turned out in quantities, at trifling expense.

It isfwithini the province of the disclosure to improve generally and. tot-enhance the utility of devices of that type to which the invention appertains.

WZith-the above and other objects in view which will appear as thedescription proceeds, the invention'resides in the combination-and arrang'ement of parts and in the de- 9 Figure 2 is a sectional View whichshows the parts as they will appear when the cord 7 is gripped;

Figure 3 is'a sectional, View showing the parts as they will appear when the cord is not gripped;

' Saving for the flexible element or cord 18,

hereinafter referred to, the device forming the subject matter of this application preferably is made of metal and includes'a disklike body 1, which, in cross section, is lensshapechas shown in Figure 1, the general construction of the body 1 being such that it will not mar any package on which it is placed. The body 1 has a. cross hole 2 located near to its edge, and in the edge of the body 1 there is a reduced bore 3 which communicates with the cross hole. The flexible element 18 has a knot or other enlargement at one end, lodged in the hole 2,

th'eborje 3, as shown in Figures 2 and thefl eXible element extending out through In'tlie etlge' oi the body 1 there is a cham:

ber e communicating with a conical passage 5 tliat, opens through the edge of the body rat apoint opposite to the chamber 4.

The device-includes a gripper which, as

a whole', is marked by the numeral 6. The parts of thegripper 6 are shown in perspectiye in Figure 5, and it will there (and elsewhere) appear that the gripper" includes a block like head"? providedwith a. thread-ed opening 8 whic'hfextends entirely through the head, as Figure 2 shows The head 7 has ribs 9 one its sides, and these en able the opening 8 to be made of considerable diameter, without using too much material in the making of the head 7. i

The gripper6- comprises tapered jaws llO that are threaded at 11 for engagement in the threaded opening 8 o fthe head The aws 10 are loosely threaded into the open-* ing 8, sothat they can swing a'little, to-

ward andaway from each other, therebyto gripfandf release the cord 18. Not much mo:

t'ion: isrequired to do this. The threads at" 11 make a strong connection between-"the jaws 10' and the head 7, and" no other pivot eleni-entris required, in'order that the jaws 10 may other."

The head 7 of the gripper 6 slides in the swing toward and away from each chamber 4 of the body 1, and the tapered I jaws 1O slide-in the conical passage 5 of the body'l; and the construction is such, obviously, that the jaws and the body may be said to have relatively inclined cooperating,

parts which close the jaws toward each other when the jaws are moved longitudinally'in one direction. The opening 8 in the head 7 serves not only to receive the threaded ends 11 of the jaws 10, but also admits the end of the cord 18which is not secured by means of'the nut or enlargement 19 to the bodyl. The free end of the cord 18 extends along longitudinal grooves 12 which are formed in the inner surfaces of the jaws 10. One. jaw has a transverse rib 14 adapted to cooperate with an oppositely disposed transverse notch 1' or seat 15 in the other jaw; and the last mentioned jaw has its own transverse rib 16 which cooperates with a transverse seat or notch 17 in the jaw which has the rib 14.

Here note that the grooves 12 extend across so relatively inclined cooperating parts which close the aws when the jaws are moved lonthe ribs 16 and 14, as shown in Figures and 2, the cord thus being held in place on the inner surfaces of the ribs 16 and 14.

The cord 18 is placed in any desired way around a package 20 of letters, or anything else which is to be tied securely. When a pull is exerted on the end 21 of the cord, in the direction of the arrow A in Figure 1, the gripper 6 slides into the position shown in Figure 3, and the operator can tighten the cord 18 as much as he pleases. WVhen the free end 21 of the cord is released, the tension in the cord moves the gripper 6 into the position shown in Figure 2, the jaws 10 moving in' the conical passage 5 of the body 1, and closing together tightly, to grip and hold the cord. Because the jaws 10 have the ribs 1 1 and 16, the cord is kinked as it is gripped (Figure 2) and is held with correspondingly increased strength; but a pull on the end 21 in the direction of the arrow A will move the jaws 10 to the released position of Figure 3, and permit the cord 18 to pay through them.

that is claimed is 1. In a device of the class described, a

body, a head slidable in the body, the head having an opening, and jaws loosely threaded into the openlng for transverse swinging movement, the ']2LWS and the body having gitudinally in one direction.

2. In a device of the class described, a'

body, a head slidable in the body, and jaws connected to the head for transverse swinging movement, the jaws and the body having relatively inclined cooperating parts which close the jaws when the jaws are moved longitudinally in one direction, the jaws being provided ontheir inner surfaces with transverse ribs which cooperate to kink and hold a flexible element.

3. In a device of the class described, a body, a head slidable in the body, and jaws connected to the head for transverse swinging noveinent, the jaws and the body having relatively inclined cooperating parts which close the jaws'when the jaws are moved longitudinally in one direction, the jaws being supplied on their inner surfaces with means for kinking a flexible element, said means comprising a transverse rib on one jaw, the inner surfaces of the jaws having longitudinal grooves for the reception of a flexible element, and one of the grooves extending across the rib. v

In a device of the class described, a body, a head slidable in the body, and jaws connected to the head for transverse swinging movement, the jaws and the body having relatively inclined cooperating parts which close the jaws when the jaws are moved longitudinally in one direction, the jaws being provided on their inner surfaces with transverse ribs which are disposed out of registration longitudinally of the jaws, each jaw having a seat for the reception of the rib of the other jaw, the jaws being equipped upon their inner surfaces with longitudinal grooves that extend across the ribs.

In testimony that we claim the foregoing V as our own, we have hereto affixed our signatures.
