.LACE-TIPPING acrame.

Application filed. September 25,1924. Serial no. 739,797. r

To all whom it may concern:

Be it known that I, I-IAnoLn D. REGAR. a citizen of the United States, residing at Reading, in thecounty of Berks and State of Pennsylvania, have invented certaln new and useful Improvements in Lace-Tipping Mach111es, of which the following is a speci- This invention relates to improvements in lace tipping machines, and it is intended more particularly as an improvement in machines for tipping laces with celluloid or like material.

The invention consists of a machine in which the tipping material is fed in the form of a ribbon or band to the tipping dies, where the required size is cut from the ribbon just prior to itsbeing pressed about the lace,

as dilferentlating from machines in which blanksare fed into the tipping dies.

1 The invention consists of a machinein which the tip forming piece of celluloid is cut, heated, pressed around the lace and severed, at one continuous movement or actuation of the machine, so that a single operation o-tmachine by the operator will complete a pair of lace tips.

Another feature of the machine is the means for applying a solvent tothe lace at the point'on which the tip is to be applied, and immediately before said application of the heated piece of cellulo d, so that the cutting of the blank, themoistening of the lace with the solvent, and the pressingof the tip and severing it follow each other so closely as tobe substantially one single action.

he invention is more fully described "in the following specification and clearly illustratedin the accompanying drawings in which:

Figures the process of wrapping the strip around the lacing.

In the drawing, Figure 1 discloses the entire machine with the support 1 and the actuating lever 2 mounted therein, which latter is provided with any suitable operating means connected through the rod 3.

14 15 and 16' are detail views showing the (i168 at difierent stages during On this support ismounted a hook 4 over which the laces are to be hung before -111- sertion into the machine to be tipped.

The numeral 5 designates reservoir to hold a supply of liquid solvent, and this is provided with a librousbody 6 projecting downwardlyfrom its opening in the lower end, and this body 6 bears lightly against the surface of the hook & so that a lace passing toward the. die will become moistened as it passes between the hook surface and the body 6. p

The numeral 10 designates the male mem her and 11 the female member of a tip form- 1ng die. The male member is carried on the end of a spring backed. rod 12 which is actuated against the tenson of its spring by the lever2. l p

Thenum'eral 15 designates a reel on which is carried a ribbon of celluloid or like material for forming thejtips. This ribbon. is fed to the point at which the male die member en'ters the female member, ready to be its lower end and the other at its upper end, so that, when the rod 12 is actuated, one screw will rotate the ratchet in one direction, to feed the. ribbon, and the other will actuate to return the parts to starting point. This ratchet device carries one of a pair of feed rolls, 26, between which and the roll 27 the ribbon 15 is held and fed downwardly through a suitable chute 28. The roll 27 is also spring backed as shown clearly in Figure 8.

The numeral 30 designates the severing knife, by means of which the tip, when formed, is severed to make the both ends of a tipped lace. This knife is located centrally in the block 31 which holds the female die, and it is immovable, the cutting being accomplished, as will be described, by a movement of both dies after the tip is formed.

The die holding block 31 is carried on a pair of parallel spring backed rods 32 mounted in the support 1 and the knife is located between. them, and projects into a central slot 35 in the die member, (see Figures 3, 10 and 11) so that the die may move against the knife.

The operation of the machine is substantially as follows:

The operator raises a lace from the hook, passes it along the upper surface thereof and beneath the moistener, where it is coated With the solvent contained in the reservoir. The lace is then lowered to the dies, resting across the female member. The lower end of the celluloid ribbon projects sufiiciently below the end of the chute 28 so that the moistened lace will contact with it as it is placed on the die. The lever 2 is then actuated, either by foot or otherwise, through the medium of the rod 3, the plunger 12 will be pressed forward against the tension of its spring, and carry with it the collar 16, which, through the medium of the yoke 17 and the screw 18, will actuate the feed rolls 26 and 27 and feed a predetermined length of the ribbon 15 down the chute.

As this movement of the plunger feeds the ribbon to the die, it also moves the male die toward the female, and as the edge of the male die reaches the female, the ribbon is sheared off and the continued movement of the male member will press the severed portion forward and around the lace. The die is provided with an electric heating attachment 40, so that the severed piece of celluloid has, through the medium of the solvent and the heat, become ready for formation into a tip and the pressure of the die members will, at this point'complete the tip formation.

At this point however the ribbon has been pressed around the lace and is still in one piece. The continued movement of the plunger 12 however, will move both of the die members and the die block 31 forward, against the compression of the springs on the rods 32 and this movement will force the lace past the cutting edge of the knife 30 and thus form the two tip ends of a lace.

The release of the. actuating lever 2 will of course, permit the spring backed plunger 12 to return, due to its spring, and this will withdraw the male member from the female and allow the tips to-fall away from the machine.

This return movement of the plunger 12 will cause a reversal also of the feed mechanism for the ribbon, and the screw 18 on the opposite side of the ratchet will come into action, while the screw through which the feed was accomplished will ride on a smooth surface over the worm on the ratchet, and thus permit the feed device to assume normal position, ready to feed again at the next forward movement of the plunger.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent is 1. In a lace tipping machine, the combination of a pair of tip forming dies, a severing knife located centrally in one member of the die, spring backed means for aetuat ing the die, means for feeding a supply of tip forming material in the form of a ribbon, feed mechanism for the ribbon comprising a pair of spring backed rollers, one of which is mounted rotatably on a ratchet device, means for actuating said roller in unison with the die, a heating attachment for the die and a moistener for the tip forming ribbon.

2. In a lace tipping machine, the combination of a liquid solvent applying attachment, a pair of tip forming dies, a spring backed plunger to which one die member is attached, means for actuating the plunger against the tension of the spring, a collar carried by the plunger, a yoke on the collar, a pair of screws carried by the yoke, a ratchet feed device for feeding, a ribbon of tip forming material to the meeting edges of the dies in unison with the movement of the plunger, and means for severing the tip when formed.

3. In a tipping machine of the character described, a tip forming die, a heater therefor, a solvent applying attachment, means for feeding a tip forming element in the form of a celluloid ribbon, a spring backed plunger on which the one die member is carried, a feed mechanism for the ribbon comprising a ratchet roller, means for actuating said roller in both directions, said ratchet actuating means being carried by the plunger, whereby the tip forming material is fed to the die in unison with the movement of the plunger.

In testimony whereof I affix my signature.

HAROLD D. REGAR.
