DAVID PELTON MOORE, OF `WASEINGTN, v:DISTRICT OF COLUMBIA.

Specication of FORMING AND FFIXING MACHINES.

Letters Patent. Patented Feb. 8, 1910 Original application vfiled June 2, 1909, Serial No. 499,797. Divided and this application filed November 30, 1909. Serial N o. 530,656.

To all vwhom, it may concern: I l B e'it known that LDAVID PELToN Moonn, a cltizen ofthe United' States, residing at Y lVashington, in the District of Columbia,

have invented cert-ain new and useful Improvements 1n Tape-Feeding Mechanisms for Tag Forming and Aliix'ing Machines, of

`which the following is a specification, refbase carrying an anvil, said casing having movements to and from the anvil, whereby the feeding mechanism is operated to feed a predetermined length of tape from a spool of tape upon the movement of the casing l away from the anvil, so that the said length may be formedl into a tag by the aforementioned cutting mechanism as the casing is moved toward the anvil and attached to the' article'by a plurality of metal staples, either as the casing is moved upon the anvil or by operating a hand lever to sever, deliver Iand clench staples through the eut tag and the article while they rest upon the anvil.

To clearly understand the invention, attention is invited to the accompanying drawings, in which:

Figure 1 is' a-sideelevation in dotted lines of my tag forming and aflining machine with the casing up, the feeding mechanism being in full lines. Fig. 2 is a` similar View from the opposite side with the casing down. Fig. 3 is a longitudinal section through the feeding mechanism, the remainder of the machine being in dotted lines. Fig. 4 is an enlarged detdil section of the feed rollers, the forwardtape guide'and the stationary tape 'guide and blade. v

Referring to thel drawings z--the numeral l designates the base of the machine carrying the stationary anvil 2, and to which is pivotally mounted'the casing -l. which is normally held upwardly by the spring 4C,

i and pulled downwardly upon the anvil by means of the rod 5, which is connected preferably to a foottreadle, not shown.

The tape which is to be fed and cut into` tags, is carried upon a spool or reel 6, the free end being passed through the forward guide 7, and between the upper and lower feed rollers 8 and 8', respectively. The lower roller 8', is journaled in the plates orside walls of the casing 3, so as not to change its lrelative position, while the upper roller 8, is mounted in slots 9, and held in a spring tensioned adjustment at each side by means of the flat springs 10, and the set-screws 11', each one ofwhich is threaded into its respective spring 10. In order to operate the feed rollers, I provide them with the meshing gears 12 and 13. and the lower rollers shaft 14, with the ratchet wheel 15, which is Voperated upon the upward movement of the casing 3, by the pawl 16, which is mounted in the lug 17, carried upon the base 1. To hold the pawl toward thc ratchet'- and in engagement therewith, I mount the spring 18 in the lug, as shown. In order to insure the proper movement of the rollers, and more particularly an even feed of wide tapes, and also lock'the rollers against a retrograde movement, I mount upon the other end of the shaft 14, the ratchet wheel 19, whose teeth O.' are rounded and separated by the substantially flat surface 21. the spring plate 22, carried upon the casing 3, having its free end 9.3, in engagement with said ratchet, so that normally the flatportion a rests upon one of the surfaces Q1, while the abutments b and abut the teeth. I have found by using this construction, that the plate Q2 greatly assists the pawl 1G, in giving an even feed to the rollers and tape, this arrangement being more advantageous than having the wheels 19 and Q1 upon the same end of the -lower roller. In order to manual-ly operate the feed rollers when the tape is being introduced through the guide 7, between the rollers S and S, and through the horizontal slot Q4, of the stationary guiding .blade 25.' Imount the milled wheel Q6, upon ling blade 25 to sever the length of tape d, Fig. 3, projected below the outerend of the cee'ding tooth of the ratch'et'vwheel l5".

casing, said blade 3l, being controlled in its vertical reciprocating movement by means -of the operating mechanism 33. To hold the slidable blade 31 toward the blade 25, I employ the spring' actuated and screw adjusted ball 85,.all of which cutting'mechanism is more particularly described in the abovel `mentioned application Serial No. 530,655.

By this construction it willbe seen 'that as the casing 3, is moved away.` from the an vll or upwardlyrthatthe pawl 16, operates 'the ratchet 15, 'causing both rollers to` rotate and project a predeterminedlength of tape..

` the vanvil 'at which time, the staple severing,

delivering and clenching mechanism 1s' op,-

"erated to Istaple the tag to the article at a plurality'of points. Upon the movement ofv `the casing toward the anvil, the pawl 1,6 is.

moved and is yready to engage the nextsuc- A The peculiar construction of the ratchet'wheel 19 and the locking spring plate 22, prevents the pawl' 16 from causing the feed rollers .to be moved too far' and also should it not move far enough, will itself' move the feed rollers the proper distance, as 4the abutments b and ,by the snapping action of the springof ,the plate 22, will snap into and between the twoftee'th and thus at. all times insure the l [pro Aer action ofthe rollers. ai()` hat Il clainnf'as new, is In a tag forming and aiixmg machine, the combination with a base, a casing 'mounted'uponthe base and capable of move- 4ments toward and away from the base, and 45' cutting mechanism for forming a tap, oif a tape 'feeding mechanism, comprising a pair efec-acting feed rollers journaled inthe cas' ing,a ratchet carried upon each end 'of one of therollers, a pawl carried by the base adapted to operate one of said ratchets asf the casing moves away from the anvil, and
