MACHINE FOR SETTING- FASTENERS.

Patented Nov. 9, 1909.

Application led December 30, 1907. Serial No. 408,561.

T o all 'whom it may concern:

Be it known that I, VALTER E. BENNETT, a citizen of the United States, and resident of Portsmouth, in the countyof Rockingham and State of New Hampshire, have invented new and useful Improvements in Machines for Setting Fasteners, of which the following is a specification.

My invention relates to a machine for setting fasteners, and particularly to a machine especially adapted for attaching a laundry tag, consisting of a flexible strip for receiving a mark provided at each end with a fasl tener, to a garment or the material of some similar articles. Such tags are made with fasteners of different forms, but all, so far as I am aware, comprise prongs projecting from the tag near its ends, intended to pierce the material to which the tag is to be attached, and to be bent or clenched thereunder. Hitherto it has been the practice to attach such tags to a garment by hand and to bend or clench the prongs with the fingers. There the tags have to be attached in large numbers and with great rapidity, as in a laundry, the hand method is too slow and is also too hard on the hands of the operator to be satisfactory.

The object of my invention is to provide a machine for doing this work, which will save time, avoid injury to the hands, and at the same time set the fasteners with as little damage to the garment as though it were done by hand.

In the accompanying drawings which illustrate one embodiment of my invention, Figure 1 is a vertical longitudinal section, partly in elevation, through the center of a machine containing my invention showing the fastener clenching means in normal or inoperative position; Fig. 2 is a front elevation of the machine in the position shown in Fig. 1; Fig. 3 is a vertical cross section on line 3 3 of Fig. 1; Fig. 4 is a vertical longitudinal section, partly in elevation, through line 4 4 of Fig. 2 showing the fastener setting means in the position it assumes after the first step in its operation; Fig. 5 is a similar view to that shown in Fig. 4, showing the fastener setting means in its final position adapted to clench the fastener; Fig. 6 is a detail view, partly in plan and partly in section, on line 6 6 of Fig. 1, of the fastener supporting memberg.

condition could be reversed without depart-V ing from the invention.

Referring to the drawings, 1 represents a bench or table on which the machine is mounted, and 2 represents a standard Vor frame for supporting the operative parts. The standard 2 is provided with jaws 4 and 5 which carry respectively the fastener-supporting means and the work-supporting and fastener-setting means. At the end of jaw 4 is an abutment or plate 7 having an inset on its under face to provide the slot 8 between it and the thin plate 9, which is made of thin sheet metal and secured to plate 7. The plate 9 is provided with a pair of slots 10, 10, spaced apart a distance corresponding with the distance between the prongs of the fasteners at either end of the tags to be set. The plate between the slots is tapered from the bases of the slots toward their openings, as shown at 11 (Fig. 6) thus making the slots nearer together at their openings than at their bases to facilitate the easier insertion of the tags into the machine. The slot 8 between the plate 9 and the abutment 7 is narrow, being of only suflicient depth to admit of the easy insertion of the body of the tag.

A pair of guideways or grooves are provided on jaw 5, comprising the side members 12, 12, the rear member 13, and front plates 14, 14, attached to the side members. A pair of blocks 15 and 16 are mounted to slide in said guideway, the upper block 15 constituting the work-supporting member and the lower block. 16 constituting the plungercarrying member. The upper block 15 is provided with a pair of apertures or recesses 17, 17 extending completely therethrough and registering with the slots 10, 10, in the fastener supporting member. Secured to block 16 are a pair of plungers 18, 18, slid-' ing in apertures 17, 17. The plungers termnate short of the end of said apertures or recesses when the machine is in normal or inoperative position, as shown in Figs. 1 to 3, but are adapted to pass completely through said recesses when in their final operative position, as shown in Fig. 5. A coil spring 19 between blocks 15 and 16 tends to urge said blocks apart;v the spring is shown as held at one end within a socket 2O in block 15, and abutting at its other end against the top of block 16. To limit the extent of the separation of said block under the influence of spring 19, a slotted plate or link 21 is screwed or otherwise secured to one of the blocks, as block 15, and a stud or screw 22 projects from the other block 16, through slot 23 of the plate 21. A recess or socket 24 is provided in ythe lower block 16 into which projects the end of lever 25, journaled at 26 to the standard 2. A slot 27 is provided in the rear member 13 of the guideway for the lever 25 to pass through. At the outer end of lever 25, a link 28 is provided which may be operated by a pedal (not shown) to actuate the blocks; or instead of a foot operating device, a handle may be provided at the end of lever 25 if desired. A spring 29 may be provided normally to hold the parts in inoperative position. The ends of the plungers 18 are con- `caved as shown at 30 to upset and clenc-h the prongs of the fastener.

The operation of the machine is as follows: A tag comprising a body portion T, (see especially Figs. 8 and 4) made of a strip of flexible material, such as tape, and pronged fasteners P secured at each end, is inserted in the fastener or tag-supporting member by passing the flexible body into slot 8 between plate 9 and abutment 7, with the prongs l), depending through slots 10, 10, of the plate 9. The breadth of plate 9 between the slots 10 being less at the entrance of the slots than at their bases,.the rapid insertion of the tag is facilitated. As the tag is pushed back into slot 8, the prongs are slightly spread apart and the body of the tag straightened out so that it lies flat and is supported in that condition between the slots by the plate. lWhen ushed back against the bases of the slots 10, 10, the prongs are in position to register with the recesses 17, 17, in block 15. The edge of the material to which the tag is to be applied is then inserted between the jaws a and 5 and power is applied to lever 25. The first movement of the lever 25 slides the blocks 15 and 16 together in the guideway to the position shown in Fig. l until block 15 is arrested by plate 7, the spring 19 holding the blocks apart in their original relation, and the plungers 18, 18, not being moved at all within block 15. This movement causes the prongsl of fasteners P to pierce the work and to enter the recesses 17, 17 without being bent. The continued movement of lever 25 next causes the block 16 to move independently, overcoming the resistance of spring 19, and sliding the plungers 18, 18, within the apertures 17, 17, (see Fig. 5) and clenching the prongs or shanks of the fastener underneath the material of the garment or the like, the plate 7 serving as an abutment or anvil member. Such relative movement between the two blocks is permitted by the slot and stud connection of the link 21. Pressure on lever 25 is then relaxed, the work-carrying and prong-clenching members return to their initial, inoperative position under the influence of the springs 29 and 19, and the work with the tag fastened thereto is withdrawn.

The operative face of the plunger 18 may be formed with a double curved surface as shown at 30 in Figs. l and 5, to direct the prongs of the fastener toward oney another and bend the points slightly into the fabric when the fastener is finally clenched; or the operative face of the plunger' may be formed with two oppositely beveled surfaces, one on either side of a diagonal line, as shown at 31, 31, in Figs. 7 and 8. This construction which is my preferred form, bendsy the prongs each a little to one side of the line of the central axis of the fastener so that the points of the prongs may extend beyond each other and lie side by side instead of lying one on top of the other as would be the case were they suiiiciently long and bent directly toward each other.
