SHOE-LACE TIP. I

I Application filed my" 17,

T 0 all whom it may concern:

Be it-known that. I, HENRY G. PETERSEN, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Shoe-Lace Tips; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to shoe lace tips.

Shoe lace tips are usually formedof metal and, as is wellknown, this type, due to the extreme thinness of the metal, has two seri' ous drawbacks. One of these drawbacks or defects is that the metal itself has not sufficient spring or rigidity to grip the lace securely, and the other drawback is that no adequate means are provided for reinforcing the tip against lateral bending.

This invention is designed to overcome the above noted defects, and objects of the invention are, therefore, to provide a metal tip for a shoe lace which will grip the lace securely without tearing it, and which is reinforced and strengthened against lateral bending.

Further objects are to provide a gripping device for shoe lace tips which is itself reinforced against bending or distortion and which will securely hold the lace in its correct position relatively to the tip.

Further objects are to provide a shoe lace tip which is of sturdy and simple design, which may be cheaply manufactured, and which will not open up when in use.

An embodiment of the invention is shown in the accompanying drawings, in which:

Figure 1 is a view of the shoe lace tip applied to the lace, with parts broken away to show the interior construction.

Figures 2, 3 and 4 are enlarged views taken on section lines 22, 33 and 4:4 of Figure 1.

Figure 5 is a sectional view taken on the line 55 of Figure 4. r

Figure 6 is the view of the blank in its extended condition.

The shoe lace tip is formed from a blank whose body portion 1 is of substantially rectangular contour, and is provided witha marginal portion 2 adapted to be folded at right angles to the adjacent portion of the rolled tip along the dotted Figure 6.

This blank is further provided with saw tooth projections 4 which, as may be'seen line 3 of 1923. Serial No. 639,668.

from Figure 6, are provided with marginal portions 5. These marginal portions, in the finished tip, are folded along the curved dotted lines 6 of Figure 6. I

Prior to the rolling operation, the material is depressed, as indicated in-dotted lines in Figure 6, to form the depressed rein forcing portions 7 of the finished tip.

The blank is further provided with a lip 8 which, as may be seen from Figures 4 and 5, is adapted to be folded'over theadjacent portions of the rolled blank at'itsrear end to prevent unrolling. Itis, of course, to be understood that-a lip of similar construction may be provided adjacent the front end.

In forming the tip the portions 5 are folded under, as indicated in dotted lines in Figure 1, and as shown in full lines in Figures Qand 4, to form a reinforced sub- 7 stantially right angle edge for the forward edge of the teeth. This provides a rounded edge in place of the otherwise sharp edge, and prevents cutting and tearing of the lace when these edges are forced therein. The marginal portion 2 extends radially inwardly to form a longitudinally extending reinforce to guard against lateral bendingof the tip. The body portionis folded around the shoe lace 9 and the tongue 8 is folded inwardly to bind the adjacent portion blank together, as may be seen from Figures 4 and 5, to prevent unrolling. It is well known that this unrolling most frequently occurs at the rear end of the tip adjacent the lace and, consequently, a lip at this point is extremely serviceable although a lip at the forward end of the tip may also be provided.

It will be seen that teeth have been provided for engaging thelace and that these teeth have rounded forward edges and are corrugated or dished so as to add to their strength.

It will further be seen that although extremely thin metal may be employed in forming these tips, that this metal is so without any tendency of the laces sliding therefrom which would occur with a tapered forward edge. This right angle front portion is backed by a relatively long tapered rear portion to provide adequate strength.

Although one form of the invention has been described in considerable detail, it is to be understood that the invention may take various forms and is, therefore, to be limited only as claimed.

I claim:

1. A shoe lace tip comprising a tubular body portion and inwardly directed reinforced teeth.

2. A shoe lace tip comprising a tubular body portion, and inwardly directed teeth adapted to project into the lace, said teeth being dished to provide stiffness to resist distortion.

3. A shoe lace tip comprising a tubular body portion and inwardly directed teeth having folded front edges.

4. A shoe lace tip comprising a sheet metal tubular body portion, teeth extending inwardly thereof, and a longitudinally extending reinforcing rib joining successive teeth and extending outwardly from the outermost of said teeth.

5. A shoe lace tip comprising a rolled metal tubular body portion having radially extending internal teeth, said teeth having a gradually tapering rear edge and a folded front edge extending transversely of the axis of said tip, and a reinforcing rib projecting radially inwardly of said tip, said reinforcing rib being of lesser width than said teeth.

6. A shoe lace tip comprising a rolled metal tubular body portion having substantially radially extending internal teeth projecting from one edge thereof, said teeth having a tapering rear edge and having a folded front edge, said teeth being dished transversely of the axis of said tip whereby increased strength is afforded said teeth against distortion.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin.
