(Cl. 24-265) This invention relates to an improved end shaped to receive them and a gripper-element clasp or fastening device for attaching the ends then rocked into engagement with the cords ad of straps, bands, bracelets or the like. jacent their ends. Because of the small dimen One object of the present invention is to pro sions of these clasps and the tendency of the GFI vide a clasp or fastening device of simple con ends of the cord to become frayed considerable struction which effects a more secure joinder difficulty has been experienced in positively grip-y of the separate parts of a band, strap or bracelet. Another object of the invention is toprovide ping the cords. `In certain of the previously used a clasp or fastening device adapted for use with bands or bracelets composed of cords or the like in which the ends of the cord or cords are gripped position where the gripper will positively engage exteriorly of a box-like body-member and then drawn forwardly into said body-member. Another object of the invention is-to provide a device of the type indicated which is neat and ornamental in appearance, capable of being economically manufactured and assembled and efficient and positive in performing its intended function. Further objects of the improvement are set forth in the following specification which de scribes a preferred form of construction ofthe device, by way of example, as illustrated by the accompanying drawing. devices it is difficult to insert the cords to a a closely twisted or substantial portion thereof 10 adjacent their ends and in other of the devices the actuation of the gripper tends‘to force the cords out of the holder or body-member. The present invention provides a fastener or end-clasp particularly adapted for use with cord 15 type bracelets although capable of use with leath er, fabric, metal-mesh or link bracelets. The >clasp of the present invention avoids the dif-> ficulties experienced with previously used de vices by providing means for gripping the cords 20 exteriorly of the body-member and then moving the gripping means into the body-member to en close and lock the cooperating parts in gripping engagement. 'I'he gripping means is moved lon In the drawing: gitudinally by an actuating member pivotally Fig. 1 is a top plan view of a cord-type bracelet showing the present invention embodied in a mounted on the body-member and pivotally con nected with the gripping means at one side of pair of clasps applied to the ends of the cords its pivotal axis. The gripper-element and actu and joined by an intermediate link; ' ating member are so constructed and arranged Fig. 2 is an enlarged bottom plan view of one of the clasps shown in Fig. l illustrated with its that rotation of the actuating member from open parts in closed gripping relationship; `per-element causes the pivotal connection be tween the elements to be shifted from one side to the other of the pivotal axis of the actuating member to effect longitudinal movement of the Fig. 3 is a longitudinal sectional view of the improved clasp taken on line 3-.3 of Fig. 2 and showing it as gripping the end of a cord-bracelet; Fig. 4 is a view similar to Fig. 3 showing the parts of the clasp in open inoperative relation Ship; Fig. 5 is a view similar to Fig. 2 showing the gripper-element in engagement with the end of a. cord-bracelet and the actuating member in re leasing position; Fig. 6 is a longitudinal sectional View of the clasp showing a relationship of the parts similar to that ulu'strated in Fig. 5 and indicating the manner in which the gripping teeth areI applied to the end of the bracelet; Fig. 7 is a view similar to Fig. 6 showing the `manner in which the clasp is closed to lock the gripper-element in engagement with the end of the bracelet; Fig. 8 is a transverse sectional view taken on vline 8-8 of Fig. 3; Fig. 9 is a transverse sectional view taken on line 9-9 of Fig. 3; and 2 Fig. 10 is a composite perspective view of th parts forming ther clasp of the present invention. In fasteners or clasps heretofore used for at taching the ends oi cord-type bracelets the ends 60 of the cords are inserted into the end of a holder position into overlying relationship with the grip gripper~element. ' La L» Fig. 1 of the drawing illustrates a cord-bracelet of usual construction comprising a pair of looped cords II and I2 having their ends gripped in fasteners or end-clasps I3 forming the subject matter of the present invention. The clasps I3 are connected together by a separable link I5 of usual construction which embraces bails I6 formed on the clasps. At the outer closed end of the loops of the cords I I and I2 are end-pieces or connecters il adapted to be attached to the balls of a Wrist-watch or similar parts of other articles of jewelry or the like. Metal loops I8 of usual construction are also provided for encir cling the cords II and I2 to hold them in parallel relationship. As more clearly shown in the detailed views of the drawing each clasp I3 comprises a box-like body-member or holder 20 having a top wall 2l of a contour corresponding with the contour- of the end of the bracelet and side Walls 22 and 23; it being understood that Figs. 2 to 10, inclusive, illustrate the clasp in inverted position or bottom side up. The bottom edges of the side walls 22 and 23 are bent inwardly to provide flanges 24 60 2 2,115,964 extending from one end of the body-member 2|! to a point adjacent the opposite end. At one end of the member 20 the walls'22 and 23 are narrowed with the top wall 2| curved down wardly in conformity therewith. Adjacent this tapered end the top wall 2| is apertured at 25 to form the bail I6, previously referred` to. The otal connection between the elements causes the gripper-element 21 to be bodily moved longitu dinally to a position where the ends of the teeth 30 underlie the top‘portion 2| of the body-mem ber 20 to secure the bracelet end to the fastener. see Fig. 9. „ To attach the ends of the cord to the end side walls 22 and 23 are provided with bearing clasp I3 the latter is placed in inverted position apertures 26 positioned above the flanges 24 ad and the actuating member 34 then rotated about 10 jacent the tapered end of the body-member. its pivotal axis to the position shown in Fig. 4 A gripper-element 21, shown in detail in Fig. to thereby displace its bearing apertures 31 en 10, is adapted for longitudinal sliding movement gaging the pintles 29 to a forward position. 'I'he in the-body-member 20 in engagement with the` forward toothed end of the gripper-element 21 flanges 24. The gripper-element 21 is in the 15 -form of a relatively narrow plate 28 having _pin tles 29 projecting laterally at one end and pref erably formed integrally with the plate. At its opposite end the gripper-element 21 is widened to form a crossbar having depending sharp 20 pointed teeth 30 for engaging the cord or other type of bracelet and a tapered or wedge-shaped spacing tooth 3| for engagement between thecords to force them apart. The crossbar at the toothed or gripping end of the element 21 forms v25 shoulders 32 projecting outwardly from the sides of the plate 28 in opposite directions for engage ment with the flanges 24 on the body-member 20. Adjacent the end of the gripper-element 21 from which the pintles 29 project the plate 28 is de 30 formed to provide a. transverse recess or groove 33 for a purpose later to be described. '. The gripper-element 21 is adapted to be drawn longitudinally into the body-member 20 by an actuating member 34 shown in detail in Fig. 10. 35 The actuating member 34 is in the form of a lever having side ñanges 35 extending from one end to a point adjacent its opposite end and at this latter end the lever is slightly curved to form a ñnger-piece 36. Adjacent the end of the actu 40 ating lever 34 opposite from the finger-piece 36 the side flanges 35 are provided with bearing ,apertures 31 for receiving the pintles 29 on the gripper-element 21 to provide a pivotal connec tion between the two elements. The opposite side 45 flanges 35 are so spaced as to straddle the plate 28 of the gripper-element 21 so that the two ele ments may be folded one over the other. The outward faces of the ilanges 35 are also adapted to llt closely between the inwardly-directed flanges 50 24 of the body-member 20 and are provided with bearing apertures 38 intermediate their ends adapted to be alined with the bearing apertures 26 in the side walls 22 and 23 of the body-mem ber 20. 'I'he actuating lever 34 is pivotally mounted on 55 the body-member 20 by a pin 39 extending through the alined bearing apertures 26 in the side walls of the body-member 20 and the aper tures 38 in the flanges 35 of the actuating mem 60 ber 34, the ends ofl the pin 39 being riveted or headed over to retain the pin in position. The actuating lever 34 when thus mounted is adapted for rotation from an open position, shown in Fig. 4, to a closed position as shown in Fig. 3, detents in the form of struck-up protuberances 65 4D being provided on the outer faces of the side iianges 35 of the lever for engagement with the inwardly-directed ilanges 24 on the body-mem ber 2U to latch the lever in its closed position. 70 During this rotation of the actuating member 34 the pivotal connection between the pintles 29 and bearing apertures 31 of the articulated actu ating and gripping elements is moved from one side to the other of the pivotal axis about which the actuator rotates. This movement of the piv will thus be positioned outwardly beyond the end of the body-member 29 so that its laterally 15 projecting shoulders 32 will clear the outer ends of the inwardly-directed flanges 24. The grip per-element 21 is next rotated on its pintles 29 to a rearward position overlying the actuating element 34 with the transverse recess or groove 20 3_3 providing a clearance for the pin 39 as shown in Fig. 4. 'I‘he ends of the bracelet cord may then be laid in the body-member 20 between the sidewalls 22 and 23. When the ends of the cord are properly positioned in the body-mem ber 20 the gripper-el^ment 21 is turned back to the position shown in Fig. 6 and the ringer pressed thereagainst to force the teeth 30 through the individual cords with the spacing tooth 3| entered between the cords || and | 2 to spread them apart. The lever-extension- or linger-piece 36 is then grasped to rotate the actuating mem ber 34 about the pivot-pin 39 as shown in Fig. '1 until the detents 40 on its side flanges 35 engage under the inwardly-directed flanges 24 >on the body-member 20 Ito latch the clasp in a closed position. During this rotation of the actuating member 34 the pivotal connection formed by the pintles 29 engaging the bearing apertures `31 at the end of the gripper-element 21 is displaced 40 from one side to the other of the pivotal axis or ` pin 39 about which the actuating lever rotates. This relative longitudinal movement of the piv otal connection between the articulated mem bers causes the toothed end of the gripper-ele ment 21 positioned exterlorly of the body-mem ber 20 to be drawn thereinto. As the gripper element 21 is pressed firmly against the cords | | and |2 its shoulders 32 are carried into engage ment with the inturned flanges 24 on the body member 20 to lock it in position with the ends 50 of the teeth 30 and 3| extending through and between the cords held in close cooperative rela tionship with the top wall 2| of the body-member to positively grip and secure the end of the cords to the clasp. When the parts of the clasp are in their closed gripping relationship the actuating member 34 overlies the gripper-element 21 to provide a'smooth under surface with the side flanges 35 positioned between the flanges 24 and straddling the plate-portion 28 of the gripper element. 60 From the foregoing description it will be ob served that the invention provides a novel con-_ struction and arrangement of elements in a fas tener or end-clasp for positively holding the ends of a bracelet. It will be further apparent that the present fastener acts to grip the ends of the cord exteriorly of the holding or body-member so that the longitudinal movement of the gripper 70 element will draw them into the holder to insure a positive grip and secure anchorage therefor. Due to this novel and improved method of op eration of the device it is not required to push the ends of the cord clear into the clasp before 75 2,115,954 closing its parts to grip the ends and, conse quently, the ends are less apt to become frayed. Moreover, since the ends of the cord are drawn into the clasp by the gripper-means instead of being pushed outwardly as in previously used de 3 5. A strap connecter comprising a body mem ber having a top wall and side walls, a finger operable member pivotally mounted on the side walls of said body member, a gripper member ec centrically pivoted on said finger operable mem vices of the present type, a much more secure . ber and having a strap gripping portion on the and permanent joinder of the ends with the clasp is effected. It will also be apparent that the fastener or 10 clasp of the present invention is of a simple con struction adapted to be easily and economically i’ree end thereof, and means on the body mem ber for cooperating with the gripper member to cause the gripping portion thereof to draw a strap into the body member when the operating 10 member is turned on its pivot in one direction of mechanical expressions without departing from the spirit of the invention. For instance, the and for clamping the strap between said gripping portion and the inner face of the mentioned top wall of the body member when the operating member has reached the limit of its movement in 16 said direction. 6. A strap connecter or the like, comprising a channel body having an inbent lug on the >edge side walls of the body-member need not extend of each side wall thereof, a finger operable mem manufactured and assembled and providing a pleasing and ornamental appearance. Although only one preferred form of the in vention is herein illustrated and described it will be apparent that the parts may have a variety 20 throughout the length thereof but instead side ber pivotally mounted between said side walls, portions or lugs only are necessary to pivotally mount the actuating member and provide a guide way for engaging the shoulders 32 on the gripper element 21. Other changes will appear to one 25 skilled in the art and so without limiting myself in this respect, I claim: l. In a device of the type indicated, the com bination of a channel-shaped body-member hav a gripper member eccentrically mounted on said ing a top, sides and an open end, a manually-oper 30 able lever pivotally mounted on the body-member, and a gripper-element pivotally connected to the manually-operable lever eccentrically of the pivot of said lever to adapt it to ‘be drawn into the body-member when the manually-operable leve!` 35 is rocked toward the body-member. 2.
