TIP-FASTENER FOR SHOE-LACES.

Specification of Letters Patent.

Patented Jan. 13, 1920.

Application filed August 23, 1918. Serial No. 251,084.

To all whom it may concern:

Be it known that I, EPHRAIM VIERTELS, a citizen of the United States, residing at the city of New York, in the county of Bronx and State of New York, have invented certain new and useful Improvements in Tip- Fasteners for Shoe-Laces, of which the following is a specification.

My invention relates to a tip fastener for shoe laces. Devices of this character are old andwell-known, and more particularly are shown in .U. S. Patent No. 1,231,103 dated June 25, 1917.

Such devices are intended to put on new tips on shoe laces, from which the original tips have been twisted ofi', and are usually operated by hand.

.Prior devices of this character have been expensive to manufacture, as they depended upon movable dies which had to be accurately made and fitted together, so that a good deal of hand work was necessary in their construction. In addition these former devices were not always reliable in their operation.

According to my present invention, a very chea and efficient apparatus is provided whic does not require any especial skill or hand work either in its construction or in the assembling of its parts.

Other objects of my invention will be mentioned in the following description and drawings which illustrate a preferred em bodiment of my invention.

Figure 1 is an elevation of my device.

Fig. 2 is a top view thereof.

Fig. 3 is an elevation with the front plate removed, and on a larger scale.

FFig. 4 is a section on the line 14 of Fig. 5 is an elevation of two intermeshing die members;

Fig. 6 is a view similar to that of Fig. 5, showin the die members reversed.

Fig. shows a shoe lace and a metal blank intended to be affixed thereto.

Fig. 8 shows the shoe lace and the metal tip affixed thereto.

Two scissor-like members 1 and 2 are pivoted at 3, and have upper portions 8 and 9, which are of equal width. These scissorli c members or l mbs and 2. have pr jece tions 4: and 5 with a spiral spring 7 secured thereto, so that the spring 7 always tends to force the limbs 1 and 2 together and maintain the die members in the position shown in Figs. 3 and 4, in which the opposite die members intermesh. It is not necessary that these oppositedie members should intermesh but this is preferred. Projections 41 and 5 .rivets 19 or other suitable means, so thatthe end of the shoe lace can be trimmed if desired.

The bodies of the members 8 and 9 are suitably hollowed to receive a series of die members 6 and 7. These die members 6 and 7 are made of steel or other material which permits their being stamped into the desired shape, so that all molding and castings are obviated. These die members 6 and 7 are arranged in two series, each of the parts 8 and 9 which may be called die supports, receiving and holding one of these series. In each of these series the die members 6 and 7 alternate and a die member 6 in one series is directly opposite to a die member 7 in the other series, so that each die member 6 intermeshes with an opposite die member 7 in the opposite series.

separated by wedge-shaped depression 32 and that the die members 7 are provided with the hollows 30 which have the same contour as the teeth 33 and are also provided with a central part having a contour corresponding to that of the depression 32. The central parts of the die members 7 have arcuate depressions 31, which cooperate with the Wedge-shaped depressions 32 to crimp and force together the edges of the metal blanks 23, which form the tips of the shoe laces.

Each die member connected to one support, as seen in the drawings, is directly opposite the opposite die member connected to the other support, so that their centers are located in and move in the same plane.

As seen in. Figs. 2 and 4, the die support It will be noted that each die member 6 is provided with two teeth 33 8 has plates 19 and ll secured thereto by I means of bolt 12, which passes through the holes 15 and 16 in the die members 6 and 7 and clamps them firmly together so that they operate as though they were integral with each other. The series of die members connected to the die support 9, are secured thereto by means of the bolt 4, which passes through the holes 15 and 16 of the die members 6 and 7 to which it is connected and also clamps them firmly together. The plate 11 has an opening 17, which is directly in line with the space between the arcuate depressions 31 and the inner ends of the wedge- Shaped depressions 32 so that if blank 23 is thrust through the opening 17, it fits between the face of these depressions, which act exactly like the face of a die of the Well-known type that is used for clamping these metal blanks 23 to the shoe lace 22.

The operation of my device is as follows When the tip of the shoe lace has fallen off the end thereof, it is trimmed off by means of the cutting members 20 and 21. Then a blank 23 is fitted over the end of the shoe lace and the shoe lace with the blank fitting over its end is inserted between the depressions 31 and the inner ends of the depressions 32. Upon forcing the limbs 1 and 2 toward each other the blanks 23 are bent so that their edges overlap, and they are then powerfully compressed upon the shoe lace so as to firmly grip it. Upon releasing the pressure upon the limbs 1 and 2, they are forced apart by the spring 7 and the retipped shoe lace can now be withdrawn.

Although the drawings illustrate the ordinary cylindrical form of shoe lace tip it is one of the marked advantages of this construction that by stamping out die members 6 and 7 to a suitable shape, a conical, corrugated, or other form of shoe lace tip may be atfixed, and the die members for different shapes of tips can be readily inserted into the die supports 8 and 9, as the bolts 41 and 12 can be readily made detachable.

I have here shown the dies as made of a series of laminations made of sheet metal but dies cast in one piece, and having the characteristics before mentioned, would be fully an equivalent thereof.

I have illustrated a preferred embodiment of my invention but it is clear that numerous changes and omissions could be made in its details without departing from its spirit.

What I claim is:

1. In a device for tipping shoelaces, die

supports, dies secured to the said die supports, the said dies being composed of a series of spaced sheet metal laminations, means for connecting the sald laminations to said supports, so that a lamination connected to one support is directly opposite an opposite lamination connected to the other support,

and means for increasing and decreasing the distance between said dies, the opposed surfaces of said dies being adapted to close a metal blank on the end of a shoelace and clamp it to the said end thereof.

2. In combination, die supports, means for moving these die supports toward and from each other, and dies connected to the said die supports, the said dies being composed of a series of laminations, eachsaid series comprising alternating members of two species, the members of one of said species having upper and lower depressions with intermediate projections having arcuate points, and the members of the other of the said species having lower and upper teeth adapted to fit into the said I upper and lower depressions, and having recesses intermediate the said upper and lower teeth, the walls of the said recesses being adapted to cooperate with the walls of the said projections, to form die-surfaces for clamping a blank on the end of a shoe lace, the members of one species in one of the said dies being opposite'members of the other of the said species in the other of the said dies.

3. In combination, die supports, means for moving said die supports toward and from each other, dies carried by the said supports, the said dies being composed of a series of laminations, each said series wmprising alternating members of two species, the members of one of said species having upper and lower depressions with intermediate projections having arcuate points, and the members of the other of the said species having lower and upper teeth adapted to fit into the said upper and lower depressions. and having recesses intermediate the said upper and lower teeth. the walls of the said recesses be ng adapted to cooperate with the walls of the said projections, to form diesurfaces for clamping a blank on the end of a shoe lace, the members of one species in one of the said dies being opposite members of the other of the said species in the other of the said dies. the said members having alined perforations and bolts passing through the said perforations and rigidly clamping the said members together and to the said supports.
