My invention relates to the attachment of price tickets to merchandise, andhas' among its ob' .iects and advantages the provision of animproved pin bender for securing pin tickets to the goods.

Ring H] fitsthe forefingerofzthdhandand: the flat extent 14 tends to restrain :the .ringrffro'm relative rotary movement on the fingen. In

severing the ring at It; the ring may be-made from metal which permits bending'to accurately fit the ring .onithe finger; but; the stiffness of the ring is such as to maintain its'shapeafter fitting for normal use. '5- 1,.

A spring steel band 16 is: riveted at 18 inter.- mediate its ends to the'finger ringv m diametrically opposite the flat extent Hl. Band l6 islof such configuration as to; tightly embrace the finger ring lfl and the ends of the band arepmvided with loops 20 for the reception ofpins 22 secured to flanges 26 along *theside margins of pin bending plates326, and28; 'Pins 22, are located at thelower ends of. the pinbendingplates 28, and the upper ends ofthe plates are'pivotally connected together by means-of a 'pin:.3fl. A

of the s The upper end. of; the pin bending. 2 6

extends slightly beyond the same'end of the plate member 28, and each'plate member is provided with a pin guiding grooveifiwhich tapers to the," Vanishing point closely adjacent .';the lower end of its respective platemember. Both grooves are; identical with the exception that .the groove in; the, plate" member .26 extends about theupper endof the plate? member, asindicated at 36in Figs. 3, aand 5. -The groovesyare arranged.-in a common line intermediate the sidemarginsof the'two'plate members 26 and'ZB, and-the-upper end of the plate member 2t is of-such curvature grooves constitute guides for, the legs 38 asthe ends thereof are pressed downwardly onjtheplate -membersg, In addition, the upper :end of the plate member 26, in being projected'beyondth'e same endaof the plate member 28, locates the groove 34 in the plate member '25 about its curved end in such a position as to guide theleg 38* pressed: therein into the groove 3d in-the plate member 28 without'obstruction. :In other Words, the:leg willtransfer smoothly from the terminus of the groove in the platemember 25 into the groove'34 in the plate member-28.- 1 In'operation, the finger ring H} is: preferably placed onthefirst finger in @such manner as to project the pivotallyconnected'ends ofthe plate members 26 andtil toward theithumb oithat hand. The staple of the price ticket, ispassed through the fabric and the staplev is positioned in'accordance with Fig. 1 Withthe'legs 38 in the groove 34 in'the upper endof the plate member 26. At thisjtime the price ticket is forced downwardly on the device; through thumb pressure which, causes the legs-38 to bend in a spreading direction. As the legs bend, the fabric is brought into engagement with the upper end of the plate member ZS-so that continued pressure on-the price ticket causes the plate members EBand 28 to be pivoted to the position'of Fig. 2, at which time the, legs 38 are bent to their final positions and in pressure engagement Withthe fabricAZ so as to efiectively secure the price ticket ML. 7

'In referring. to Fig. 2,- it will'be noted that the : platemenibers 26 and 28 pivot to positions which bring the axis-of the .pintllbeneath a straight :line passing. through the axes of thepinsgfi; .The final positionof theplate members 2% and 128, as in Fig.2, is determined by stopsM' which In Fig. 1, the angular alignment of the plate members 26 and 28 is such as to facilitate pas- ....concerned and restrain the tension spring I28 sage of the two plate members between the legs 38 as pressure is exerted on the price ticket. To

secure close pressure engagement between the legs 38 and the fabric 42, the plate members pivot to the position of Fig. 2 so as to impart sufiicient bend to the legs for securing such engagement.

In pivoting the plate members and 28 from the positions of Fig. 1 to the positions of Fig. 2, the band I6 is flexed and the tension spring 32 is elongated. Both the band and the spring exert a pull on the plate members 26 and 28 in the direction of the pin 30, and the plate member 20 is provided with an enlargement 46 which engages the coil spring 32 intermediate its ends and bends it to a position between the two stops 44. Because of the bend in the coil spring, the latter exerts pressure on the enlargement 46 and pivots the two plate members to bring the axis of the pin above a straight line extended through the axes of the pins 22. As the pivoted end of the two plate members is moved a predetermined distance by the coil spring 32, the coil spring and the band I6 snap the two plate members back to the normal positions of Figs. 1. and 5. In vanishing the grooves 34 near the outer ends of the plate members 26, the angular contour of the grooves also facilitates final bending of the legs 38 and expose the outer end margins of the legs to the fabric so that these ends may be pressed firmly thereagainst.

In Figs. 6 and '7, the finger ring 46 is provided with two flanges 48 which carry pins 50extending loosely through slots 52 in the flanges 54 along the side margins of pin bending plates 55 and 58, each of which is provided with two pin guiding grooves 60. The plates are pivotally connected together in the same manner as the plate members 20 and 28 by a pin 62. A tension spring 64 has its ends connected to lugs 65 secured to the inner faces of the plates near their I lower ends. Spring 04 is located between the two flanges 48, which flanges are recessed at 68 to provide accommodation for the enlargement 10 on the plate 56 as the two plates pivot to their pin bending positions, so that the flanges 48 constitute stops. Plates 58 and 58 function in the same manner as the plate members 26 and 28, and the grooves are identical with the grooves 34. Since the tension spring 64 is normally located considerably above the bottoms of the recesses 68, the enlargement ID will, of course, flex the spring as the two plates are moved to their final positions for pin bending purposes, so that the spring 64 will act to kick the pivoted ends of the two plates and move the axis of the pin 62 above the straight line passing through the axes of the pins 50.

According to Figs. 8 and 9, the plates 12 and 14 are identical with the plates 56 and 58, with the exception that crossedbars 16 are pivotally connected with ears 18 on the finger ring 80 by means of pins 82, and to the plates by means of pins 84 carried by lugs 86 also secured to the plates. A pin 88 pivotally connects the upper ends of the ;plates I2 and 14 one to the other, and each plate is provided with two grooves 90.

Fig. 8 illustrates the upper ends of the bars 16 as being provided with flat ends I24 having engagement with the inner faces of the plates 12 and 14 in their normal positions. The lower ends of the bars are also provided with faces I26 which engage the finger ring 80. These faces provide a stabilizing action for the parts from urging the plates I2 and I4 beyond their ;-normal positions of Fig. 8.

In the structure of Figs. 10 and 11, the finger ring 92 is rectangular in contour but is severed at 94. To the end wall 98 is secured two pins 98 which ride freely in a slot I00 in a bar I02 held closely to the end wall 96 by the heads I04 of the pins 98. The pin bending plates I06 and I08 are provided with pin guiding grooves H0, and.th'e upper ends of the two plates are pivotally connected one to the other by a pin 2. Pin II2 also extends through an opening in theupper end of the bar I02, and the lower ends of the plates normally ride on the upper wall I I4 of the finger ring, with the lower pin 98 lying at the bottom end of the slot I02 so as to restrain the two plates from pivotal movement in the direction of each other beyond the positions of Fig. 10.

The plates are recessed at I I6 for accommodating a coil spring II8 having legs I20 lying in grooves I22 in the plates I06 and I08 for pivoting the plates in the direction of 'each other. When pressure is applied to the upper ends of the plates I06 and I08, the bar I02 slides downwardly of the finger ring 92, since the pins 98 fit loosely in the slot but support the bar at right angles to the longitudinal axis of the finger ring 92. The tension of the coil spring I I8 is such as to snap the plates to their normal positions of Fig. 10.

Having thus described certain embodiments of my invention in detail, it is, of course, understood that I do not; desire to limit the scope thereof to the exact details set forth except insofar as those details may be defined in the appended claims. I v
