Serial No. 112,690.

To all whom it may concern:

Be it known that I, FRANCIS W. HARKINs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new Fabrlc- Clasp, of which the following is a specification.

My invention relates to improvements in fastening devices by which articles are fastened together, such as a sleeve, hose or other supporter more particularly, and the ob ect of my invention is to provide means of quickly and securely accomplishing this result. I attain this result by the invention illustrated in the accompanying drawing in which Figure 1 shows the device, made of sheet metal for heavy fabrics, as closed, the ball for greater clearness being shown as unused. Fig. 2 represents the device as open and as made of wire flattened out sufliciently in parts for use with light fabrics. In Figs. 1, 2, the device is shown attached to ends of the connecting band or webbing. Fig. 3 is a view of one of the arms in Fig. 1 showing The two arms A and B of the device (Figs. 3, f) have their ends d, n, OZ N shaped into hooks, both hooks of each arm turned in the same direction, so that when assembled and associated to ether in the device, (Figs. 1, 2) these hooks ace each other in pairs, hook cl facing hook cl and hook a facing hook N. Interference of these hooks is prevented by one arm being placed upon the other. Hook n may be provided with a stud R that works in a slot 1" of hook N and serves to hold hooks n and N in place. Stud R also acts as a pivot around which the arms rock when hooks d, d are opened or parted widely. Arms A and B are bowed at bows S S to secure their proper working. When con structed of sheet material, especially, they are also provided with enlarged bellies O, O to allow the greater elongation of the slot on of arm A, necessary when heavy materials are to be connected. Arm A is provided with the slot on for the reception of stud b of ar m B it also has the stud R which works in the slot 0 of arm B. But this slot 1" of arm 13 and stud R of arm A may be disa portion of the attached spring. Fig. 1 is pensed with in case an ear 6 is turned over a View of the other arm in Fig. 1 showing on hook N of arm B to form a housing for the rest of the spring. Fig. 5 is a plan of hook at of arm A, as shown in Figs. 1a, 15, the guard for the closed device. Fig. 6 is or both may be usedas shown in Fig. 1. Or, a front view of the guard. Fig. 7 is an elelnstead of the houslng or ear 6 of Fig. 1, a

sleeve 0 Fig. 2 may be used to the same purpose, namely, to keep the hooks n, N together and to prevent interference of the webbing M with their action. Sleeve 6 and stud It, working in slot 0" may both be used together as shown in Fig. 2.

In the device the two arms A and B are associated together by means of the stud b of arm B made to work loosely in the slot a of arm A, stud 6 being provided with an enlarged head to prevent the disassociation of the arms. The slot a is slightly curved to lessen friction and allow the free movement of the movable pivot b which, on the hooks (Z, cl opening to their widest extent, must move over the arc of a circle. In Fig. 1 this slot a is shown somewhat elongated to secure more movement of the stud or moving pivot 7), this movement being especially required by the greater opening necessary to admit the thicker material to be connected, a construction allowed by the clasp being made of sheet material instead of wire as in Fig. 2. The arms A and 13 Figs. 1, 14: are also connected together by the spring E,

vation of the stud used to pin or pivot the arms together. Fig. 8 is a section of a portion of Fig. 1 made on the plane :0 y. Fig. 9 is a section of a portion of Fig. 2 made on the plane 9 2. On the second sheet of drawings, Fig. 10 is an edge view of the device shown in Fig. 1, in the direction of the arrow, omitting ball and webbing. Fig. 11 is an edge view of the device shown in Fig. 2, in the direction of the arrow omitting ball, webbing and spring. Fig. 12 is a transverse section on line to o of Fig. 10, while Fig. 13 is a transverse section on line g t of Flg. 11. Fig. 1A is a modified rear view of the clasp as seen in Fig. 1, omitting the webbing and the stud It connecting the large hooks. Fig. 15 is a modified perspective view of the clasp as shown in Fig. 1 1,

necting the large hooks and shown closed. Fig. 16 is the device shown in Fig. 1 except that the ball K is shown in position in use to hold the material K.

By having which ball-like substance on being enfolded 1 in said flexible material makes an enlargement of the same or head, and on being embraced immediately below the head, by one pair of hooks of the clasp, prevents the slipping of the material and its disengagement from the clasp, substantially as described, for the purpose specified.

3. A device for the connection of articles having arms A and B placed one above the other pivoted by a movable pin b, which is at right angles to the arms A and B and connected together by spring E, arm A being made with a transverse curved slot a to allow a free movement of the pivot b when moving over the arc of a circle on the action of the arms, arm A being made with hooks (Z and a, both turned in the same direction, arm B being made with hooks cl, N both turned in the same direction, all parts being formed and associated so that on hooks N and 'n being forced toward each other, the hooks d, d usually held together by the force of the spring E are separate for the reception of a part of the articles to be connected, substantially as described, for the purpose specified.

A,-one end shaped into the the other end shaped into the hook at, both hooks being turned in the same direction, having the transverse slot a curved in the arc of a circle, arm B superimposed on arm A, and having the pivot 79 adapted to work in the slot at of arm A and one end shaped into hook cl, the other end shaped into the hook N which has an ear e turned over for a housing of hook a, in combination with spring E that has one end fastened to arm A and the other end fastened to arm 13, all parts being made and arranged so that the hooks d, cl are held closed by the force of the spring E but on the hooks N, n being forced together sufficiently the arms A, B are separated and the hooks d, d opened to the extent allowed by slot 64 for the reception of the material to be connected, substantially as shown and described, for the purpose set forth.

7. A hooking device for the attachment of a flexible material consisting of two arms, one superimposed on the other, so as to move in different planes, having their upper and lower surfaces parallel so as to allow the end of one arm to slip by that of the other arm, each arm having its ends turned into hooks in the same direction, the two arms pivote together by a pivot on one arm perpendicular to that arm and made to move in a transverse arched slot of the other arm and actuated by a spring connecting the two arms, in combination with aball enveloped in the material to be connected, substantially as shown and described, for the purpose specified.

8. A hooking device for the attachment of a flexible material consisting of two arms, one superimposed on the other so as to lie in different planes having their upper and lower surfaces parallel so as to allow the end of one arm to slip by that of the other arm, each arm having its ends turned into hooks in the same direction, the two arms pivote together by a pivot on one arm perpendicular to that arm, their lower hooks kept from separating sidewise by a pin of one arm, said pin working in a slot of the other arm, the two arms being united by a spring that serves to keep the hooks at one end of the arms together and the hooks at the other end apart, in combination with a ball suited to enfold in the material to be attached, substantially as described for the purpose set forth.

9. A hooking device consisting of two arms, one superimposed on the other so as to lie in different planes, each arm having which connects them in combination With a ball by Which when enfolded in the material 10 to be connected the slipping of the material embraced by the hooks is prevented, substantially as described for the purpose specified.
