Description

June 7, 1949. E. GRIMES LEATHER LACE SKIVER Filed June 28, 1948 Patented June 7, 1949 UNITED STATES QFFICE 12 Claims.

This invention relates to a leather lace skiver.

The main objects of this invention are:

First, to provide a leather lace skiver adapted to cut the under libre off leather lace to make the lace relatively very thin to facilitate readily lacing the same around leather edges in various leather craft items such as womens purses, billfolds, wallets and the like and when so laced producing a protective and highly ornamental beading for such edges.

Second, to provide leather lace skiver of the type above described which may be readily adjusted to produce laces of different thicknesses suitable for various leather craft articles.

Third, to provide a skiver of the type above described which is eicient in operation and which may be very economically produced.

Objects relating to detail and economies of the invention will appear from the description to follow. The invention is dened and pointed out in the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:

Fig. 1 is a perspective view of the skiver, this view also showing a lace in the skiver having its inner fibre side cut away.

Fig. 2 is a longitudinal vertical sectional view of the skiver on the line 2-2 of Fig. 4.

Fig. 3 is a vertical longitudinal section corresponding to that of Fig. 2 showing a detail including the cutting blade and associated parts on a greatly enlarged scale, the View also showing the lace and the same being skived.

Fig. 4 is a transverse vertical section of the skiver on the line 4 4 of Fig. 2.

Fig. 5 is an enlarged detail top plan View of that portion of the base of the skiver, which supports the cutting blade.

In the embodiment of the invention illustrated the numeral I designates the base member of the skiver, which may be made of aluminum, plastic or any other suitable material. The upper surface of the base is provided with a transverse recess or depression 2 having intermediate the side edges 3 thereof a convexedly curved portion 4 constituting means for supporting the cutting blade 5 thereon. This blade is provided with the opposite cutting edges 6 and l' and is made of a relatively thin flat resilient sheet metal adapted to be resiliently flexed into a curved cutting position over the convex raised portion Il and held in such position by the guard plate 8. Headed screws 9 extend through the openings I0 in the guard plate and are screw threaded into the openings I2 in the base member I. By adjustment of the screws 9 the degree of curvature of the cutting blade 5 may be varied, the inherent resiliency of the blade at all times retaining the blade against the bottom wall of the guard plate during such adjustments.

A lace supporting spring I3 supports a lace I4 in cutting relation to the edge 6 of the cutting blade. This spring is disposed in an upwardly opening groove or elongated recess I5 extending longitudinally in the upper face of the base member I and is secured in the rforward end of the groove by means of the headed screw I5 threaded into the base member. An adjusting screw Il provided with a knurled head I8 is threaded through the opening I9 in the bottom wall 2) of the groove I5 and engages the lower surface of the lace supporting spring to vertically adjust the same against the tension of the spring to different positions relative to the cutting edge 6 of the blade whereby the thickness of the lace may be varied.

The guard plate 8 is provided in the front edge thereof with laterally spaced lace guiding recesses 2| and 22 of different widths, the recess 2| being for a lace of one width and the recess 22 being for a lace of a narrower width. Obviously the number of these lace guiding recesses of different widths may be increased. The side walls 23 and 24 of the recess 2| guidingly engage the opposite side edges of the lace I4 and the rear wall 25 of this recess guidingly engages the lower surface of the cut ol portion 26 of the lace. The guiding recess 22 is similarly provided with guiding walls. When the edge 6 of the blade becomes dull the blade may be reversed and the edge 'I used instead.

Grooves 21 and 28 are provided in the upper surface of the base member I forward the front end of the spring receiving groove I5, for guiding laces towards the guiding recesses 2l and 22 respectively in the guard plate 8.

In operation, the base member is held in one hand and the lace is drawn through the skiver against the edge 6 of the blade with the other hand, a suitable tension if desired may be put on the lace by pressing downwardly with the hand on the lace I4 either in the groove 21 or on top of the lace supporting spring I3, while the lace is being pulled through the skiver.

The construction above described is adapted for the ready and eiiicient production of very thin laces, for example down to 1/54 of an inch in thickness and less, such thin laces being very desirable in the production of highly ornamental bead-like lace protective edgings for various articles such as Womens purses, bill-folds, wallets and the like.

I have illustrated and described my invention in a very practical embodiment thereof. I have not attempted to illustrate or describe other embodiments or adaptations as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired.

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