TAG-ATTACHING DEVICE.

Application filed September 8, 1910. Serial N 0. 580,972.

To all whom it may concern.-

Be it known that 1, JAMES F. DAVIS, a citizen of the United States, residing in the city and county of Camden, State of New Jersey, have invented a new and useful Tag- Attaching Device, of which the following is a specification.

My invention consists of an improved stapling machine.

It further consists of improvements upon a stapling machine for which Letters Patent No. 597,773, were granted to Eldridge R. Johnson, assignor to New Jersey Wire Stitching Machine Company,-on January 25th,1898.

Figure 1 represents a side elevation of a stapling machine embodying my invention. Fig. 2 represents a rear elevation of said machine. Figs. 3 and 4: represent cross sections of the horn illustrating the clenching jaws in different positions. Fig. 5 represents a vertical sect-ion of the upper end of the column and the arm of the machine frame, and of the adjustable horn illustrating operating parts embodying my invention. Figs. 6 and 7 represent respectively a face view and a side view of an eccentric. Fig. 8 represents a plan view of the horn and a horizontal section of a portion of the column. Fig. 9 represents a plan view of a portion of a detachable table. Fig.- 10 represents an edge view of said table.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings the machine has an upright base 1, upon which is secured a vertical column 2, terminating at its upper end in a horizontal overhanging arm 3. main shaft 4, is journaled in said horizontal arm and carries a loose drive-pulley 5, to which the driving power is applied. Suitable clutch mechanism 6 controlled by a treadle 7, is provided to engage and disengage the pulley and shaft to drive and stop the latter. These elements are substantially the same as those disclosed in the above named patent and need no detail description nor illustration.

At the forward end of the horizontal arm is supported a head or casing 8, having a support 9, carrying a spool or reel 10, holding wire and feed rollers 11 connected to the drive-shaft to be actuated from the same, are also supported from said head. These parts are also substantially the same as those disclosed in the patent referred to, and it is not necessary to describe or illustrate the same in detail. A wire-cutting and stapleforming mechanism 12, is also supported on the head, and is connected to a crank pin 13, upon the drive-shaft to be reciprocated by the same, all of said elements being the same as those disclosed in the above-stated patent, and consequently, needing no detailed description or illustration.

The staple driver or plunger is indicated by the numeral 14.

The front face of the column 2 is formed with a vertical guide formed by a plane face 15, having a vertical groove 16, in the bottom of which is formed a vertical slot 17. A hollow horn or bracket 18 which forms a work support, has a tongue 19 upon its inner end, which tongue engages and is slidable in the groove. The inner end of the horn is formed. with a vertical slot 20, through which passes a screw bolt, 21, engaging a threaded hole in the bottom of the groove of the column. The head of this bolt bears against a washer 22, spanning the slot at the outer side of the base 23 of the horn, and a handle 24, is pivoted to the head of this clamping bolt to facilitate the turning of the same. An adjusting screw 25, is journaled to turn in a lip 26, projecting from the face' of the column, and has a handle for turning it and engages a threaded bore in the base of the horn, so that the latter may be accurately moved up and down upon the face of the column and be clamped in its adjusted position by the clamping bolt. A stop 27, at the upper end of the groove in the face of the column serves to limit the up ward adjusting movement of the horn. The upper face of the horn is fiat and has preferaly rounded edges and corners. A slotted gage 28, is adjustably secured upon the upper face of the horn by a set screw 29. A

pair of substantially triangular cams or clenching jaws 30, are pivoted at their outer corners near the outer end of the horn and transverse to the same, beneath a transverse slot 31, in the top of the horn, and the edges of said jaws which present upward are inclined toward each other when in active position to'engage and convergingly bend the legs of a staple forced downward against them, as will appear in Figs. 3 and 4. A bell-crank shaped cam 32, istransversely journaled to rock in the outer end of the horn, beneath the clenching jaws, so as to have its forwardly projecting leaf engage the lower points of the clenching jaws. The downwardly projecting leaf of the cam is held by springs 33, against the forward end of a rod 34, sliding in a guide 35, in the horn, and the inner end of said rod is pivoted to the depending arm of a bell-crank 36, fulcrumed in the column and having a pin 37,

upon the end of its laterally projecting arm. Said pin engages a slot 38, in an eccentric rod 39, the strap 40 of which fits upon an eccentric 41, upon the drive-shaft. The slot provides a limited amount of lost motion so that the bell-crank will only be rocked during a part of the reciprocation of the eccentric rod.

By means of the above described mechanism the bell crank will be rocked during a 7 part of each revolution of the drive-shaft so as to push the rod forward and bring the forward leaf of the cam against the points of the clenching jaws, rocking the same to bend inward and clench upward -the legs of the staple, as shown in Fig. 4.

The slot in the bell-crank will provide sufficient lost motion to permit the drive-shaft to revolve and actuate the wire-cutting and staple-forming and driving mechanism before actuating the clenching mechanism.

This machine while capable of use whereever wire stitching or fastening by staples is required, is particularly designed for fastening price tags, size tags or similar tags or cards to textile goods, and the horn is particularly adapted to have stockings, sleeves of garments and similar articles slipped over it, so as not to secure the tag or card to more than one layer of fabric.

-- When, however, the machine is used to fasten tags or cards to fiat and wide articles, it becomes desirable to provide a wider support than the narrow top of the horn. To provide for such contingency, I employ the device illustrated in Figs. 9 and 10.

Copies of this patent may be obtained. for

' retain the table upon the same.

In practice the horn is adjusted upon the column according to the thickness of the tag and article to be tagged, so as to bring the clenching jaws at the proper height to force the legs of the staple into the underside of the fabric, whereupon the machine is started. The article to be tagged. and the su perimposed tag are now placed upon the horn. If the article is a stocking or similar tubular article, and it is desired to not close both sides of the same together by the staple, the article is slipped over the horn to only present the layer or layers desired to have the staple pass through. If the article is large and flat, the table is adjusted upon the horn. The gage upon the face of the horn is adjusted to gage the proper distance from the edge of the article at which the staple is to be placed. The machine is now started by depressing the treadle, and the wire will be fed forward, the proper length of wire will be cut ofi, the staple will be formed, and finally the staple so formed will be driven through the tag and fabric. As the legs of the staple pass through the tag and fabric, and their ends strike the converging edges of the clenching jaws, said legs will be bent inward, as seen in Fig. .3, until the driving plunger has driven 'the staple home, when the clenching jaws are swung upward, bending the legs of the staple up against the fabric and clenching them, as illustrated in Fig. 4 of the drawings.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

In a machine of the character stated, a supporting column, a drive-shaft journaled at the upper end of the column, a hollow Work-support, a pair of substantially triangular clenching jaws pivoted transversely at their outer corners near the outer end of the work-support, a bell crank shaped cam member transversely journaled in the outer end of the work-support to have its forward leaf engage the depending points of the jaws, an eccentric upon the drive shaft, an eccentric rod connected to said eccentric and formed with a longitudinal slot, a bell-crank having a pin upon one arm engaging said slot, and a rod pivoted to the depending arm of the bell-crank and guided in the hollow work-support to have its outer end engage the depending leaf of the cam member.
