To all whom itmay concern.-

Be it known that i, ARTHUR resident of the town of North Attleboro, in the county'hi Bristoland State of Massachusetts, have invented certain new and useful Improvements in Dies for Forming Lacing- Tips; and 1 do hereby declare ing is aful'l, clear, and exact description thereoflmference being bad to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to means for forming tips on lacings, and has for its object to provide a punch and die that will act upon the lacing to condense a portion of the same and Wrap a covering around the said condensed portion.

To form and cover a tip in this die, the covering, which may be of paper, fabric, or other suitable flexible material, is coated with a layer of-cement and placed on the recessed portion oiithe die. The lacing is next placed, onto. this covering material, and both are then the recessed portion of the die by suitable means. The plunger or punch is then driven down into the recess and on account of its concaved face rolls the lacing up inside of the covering, the whole being tightly forced together and held by the cement. The die and plunger are so arranged that just before the plunger reaches the end of itsdownward stroke the braid and covering are both severed, and as the die proceeds it turns the covering nicely over the end of the lacing, leaving-a smooth and handsome finished tip with a round end.

The invention isiully set forth in this specification and more particularly pointed out in the appended claims.

in accompanying drawings, Figure 1 is a perspective view showing the die with the punch withdrawn therefrom. Fig. 2 is an enlarged view representing a portion of the punch withdrawn from the die and partly in section illustrating the concaved or rounded portion for cutting the lacing and covering'in two. Fig. 3 represents the die in section and the rounded portions, which, together with the concaved portion of the plunger, forms the tip with the rounded ends. Fig. 4 shows an end elevation of the punch and die, showing the covering and lacing drawn into the slot in the die and the punch entering said slot Fig. 5 illustrates the punch as having engaged the covering and in the act of rolling Specification of Letters Patent. application filed March 24, 1905.

position and having rolled the lacing and compressed the covering around the same. Fig. 7 is a side elevation, partly in section, illustrating the punch as having coverhd and formed the tip with nicely-rounded ends. Fig. 8 is a detail perspective view of the cutting and shaping block.

Referring tothe drawings, at l is the dieholder, that may be secured in any suitable manner to the bed of the press or other operating mechanism. In this holder is preferably keyed the die-block 2. Into the face of this block are out two deep slots 3 and 4,running at right angles one to the other., The bottom of slot 3 is preferably made rounding or semicircular in form, as shown at 5. The slot .4 in this block is made much deeper than slot 3 and square at its bottom. into this last-mentioned slot is set and fixed the cutting and end-forming airlock 6, the said slot i being made exclusively for its reception. The

upper edge of this block when in position in 'liJS slot extends a short distance above the bottom of slot 3, and this upper edge is preferably formed with an inwardly-cut e, leaving said edges 7 7 sharp for severing the lace and covering when forced down upon said edges. The portion of this block where it crosses the slot 3 is cutaway and rounded out on both sides thereof at 8 8 into a semicircular form to conform in width to slot 3. 'lhebottom of both of these cut-out portions are made quadrispherical in form, as illustrated in the drawings. The punch or plunger 9 is made to lit the said slot 3 in the die. Said plunger is divided or siotted at 10 for a portion of its height. The edges of this slotted portion are rounded oh so as to straddle and lit the cutout portion 8 8 01 the cutter-block. The upper end of this slotted portion 10 terminates in an enlarged hole 11, which hole serves to free the pieces that are carried up said slot after they are cut from the laces. The lower edges ofthis bifurcated punch are formed concaved or half round at 12 12, except at the points adjacent the slot, where the semicircular portion is rounded into a quadrispherical form, thereby providing cutting edges 13 13 on the punch, and at the same time completing the rounding form, which, together with that in the cutter-block,forms the rounded end of the tip, as best illustrated in Fig. 7.

The shape of the bottom of the slots 3, as well as the groove 12 in the punch-blade, may

Fig. 6 illustrated in Fig. i.

be made square, oval, hexagonal, octagonal,

' or ofanyother form into which it may be desired to press the tip.

The action of this punch and die may be further described as follows: The die 2 may be held to the bed of the press or other operating-machine in any desired manner and the punch reciprocated in the usual way by a sliding head, if desired. The flexible covering is out about the length of two tips and wide enough to be conveniently wrapped around the lacing after the same has been condensed. This covering, after it has receiveda layer of cement on its inner surface, is placed either by hand or mechanically over the slot 3 on the die. The lacing is then carried in any convenient manner'over the covering. The whole is then forced or carried down into the die, where it is drawn up into the form illusihe plunger 9 then enters the die,.and the edges it it of the concaved portion engage the covering 15 androll it inward over and around the lacing 16. As theplunger 9 nears the bottom of the groove 3 the cutting edges 13 13 of said plunger coacting with those on the cutter-block 7 7 shear out a small piece 17 (see Fig. 7) of the lacing and the covering, and as the plunger continues to move downward the-covering is rolled closer and closer around the lacing until the wholeiscompressed into acylindrical form,

and on account of the semispherical shape of the dies the ends oi both of the tips are nicely rounded,'thereby producing two lacing-tips of a handsome and finished appearance in one operation of the punch and die.

Having thus described my invention, what I claim as new,:and desire to secure by Letters Patent, is
