TIPPING HAN D.-'.1OOL.

Specification of Letters Patent.

PatentedSept. 2, 1919.

Application filed June 11, 1918. Serial No. 239,371.

Lawrence, in the county of Essex and'State of Massachusetts, have invented certain new and useful Improvements in Tipping Hand- Tools, of which the fOllOWing is a specification.

This invention relates to means for providing shoe lace ends with stiffening tlps, and refers particularly to tools to be operated by hand for firmly clenching the tips onto and around the lacing.

The object of the invention is to provlde a simple and easily operated hand tool having ample power to clench the tips immovably on the lacing and to do the work accurately and uniformly.

To this end, the invention consists in the construction and combination of parts of the tool substantially as hereinafter :described and claimed.

Of the accompanying drawings:

Figure 1 is a side elevation of the tool.

Fig. 2 is an end view from the left of Fi 1.

Fig. 3 represents a section on line 33 of Fig. 2.

Figs. 4, 5, 6 and 7 are detail views on a larger scale illustrating successive operations hereinafter described.

The tool comprises a pair of lever members crossing each other and pivotally connected at 12 and having handle portions 13 and relatively short arms 14. The handles 13 are normally held apart by a suitable spring 15 to a limit determined by cooperating shoulders 16, 17.

The intermeshing or interengaging dles are carried by the short arms 14 of the lever members. The female die 18 has lugs 19 straddling the end of one of the lever arms 14 and pivotally or hingedly connected thereto by a pin 20 preferably headed at both ends like a rivet. The other end of the member 18 has a deep recess 21 the bottom of which is semi-circular in contour. The male die 22 has lugs 23 straddling the end of the other lever arm 14 and pivotally or hingedly connected thereto by a pin 24, similar to pin 20. The other end of the member 22 is reduced to form a rib 25 with shoulders 26. Said rib is so proportioned as to section the grooved edge 27 of said rib coacts with the curved bottom of recess 21 in presenting a substantially tubular space. In other words, the stop shoulder structure described accurately limits the closing or operative movements of the dies and prevents the sharp edges of rib 25 from being injured or cutting into and marring the rounded bottom of recess 21. Since the cooperating stop members are carried by the dies themselves, it is easy to re-fitthe device for use after wear, because the bottom of the recess 21 can be re-shaped, and the grooved edge of rib 25 also l e-shaped or sharpened, and then stop shoulder orshoulders26 reduced or ground to enable the tip forming surfaces to again accurately cooperate.

"The stiffening tips a-may be of any of the well-known materials, longitudinally U- shaped and having a row of perforations to form inwardly-extending tongues to enter the lacing material 6 as usual.

In operation, the user of the tool first places the end of the lacing in a tip a while the latter is in the form shown in Fig. 4 and pinches the tip to close it (see Fig. 5) sufficiently on the lacing to .cause it to remain there until inserted between the dies of the tool as indicated in Fig. 6. The handles 13 are then moved toward each other until further movement is arrested by the stop shoulder structure of the dies. This causes the sharp edges of the die rib 25 to ride down outside the edges of the tip a and close them, one usually in advance of the other, the proportions of the handles 13 relatively to the arms 14 which carry the dies being such that ample force can be brought to bear to finally roll the tip tightly around the lace end, (Fig. '7). During the closing movement of the tool, the dies slide freely toward each other owing to their pivotalconnection with the arms 14. When hand pressure on the blanks 13 is re leased, the spring 15 parts them and causes the dies to slide apart far enough to release the tipped lacing. The stop shoulders 16, 17, however prevent such opening movement as to remove die rib 25 entirely from die recess 21, these parts remaining in suflicient (preliminary pinching toward the ientlydone by hand, it can be easily efiectgether.

'vided by the grooved edge I that, first,

ed by inserting-the edges of the tip a, While in the Fig. 4 position, in the space between the outer shoulder 26 of die 18, and then closing the dies so. that said shoulder 26 and opposing portion of die 18 will pinch the edges of the tipto- It is easy to so hold the parts and manipulate the tool that one edge of tip a is closed in more than the other edge.

It will therefore be clear that I have provided a tool of thecharacter described having-two clenching portions, viz: the closing jaws provided'by the outer shoulder 26 of die 22 and the opposing surface of die 18, and the shaping or collapsing surfaces pro- 27 of die 22' and the opposing curved bottom of recess 21.

This double function results from the fact the dies are pivoted in accessible positions to the outer faces of the short arms 14:, and, second, the shoulder 26 is Copies of thispatent may be obtained for five cents each, by addressing the. Commissioner of Patents,

and the opposing edge formed on the outer, exposed, surface of die 22 Where it is readily accessible for the lateral introduction of the lacing and tip for the preliminary pinching or closing ustdescribed.

It is to be understood that I do not limit myself to the operation exactly as described. Instead of placing the lacing and tipin the position indicated in Fig. 7 they may be inserted with the round mid-wldth portion of J the tip opposite the grooved edge 27' of the male die so that in operation the edges Will said recess to provide a clenching portion,.

the outer exposed surface of one of the dies being provided with a shoulder to coact With a portion of the other die to provide preliminary pinching members in accessible positions.

In testimony whereof I have afiixed my 7 signature.
