UNITED STATES Trice.
PATENT CHARLES H. TRASK AND J. B. JOHNSON, OF LYNN, ASSlGNORS TO THEM- SELVES-AND G. L. THAYER, OF BOSTON, MASSACHUSETTS.
IMPROVEMENT IN BOOTS AND SHOES.
Specification forming part of Letters Patent No. 52,798, dated February 20, 1866.
To all whom it may concern.-
Beit known that we, CHARLES H. TRAsK and JOSEPH B. JOHNSON, ot' Lynn, in the county of Essex and State of Massachusetts, have invented a new and useful improvement in channeling the soles of shoes for the re' hibit them as closed.
The common channel, as used with the Mc- Kay sewing-machine, has but one closing-lip, 13,(see Figs. 1 and 3,) such lip, when depressed, resting in an angular notch or seat, b c d, extending t'rom the channel, which, in Figs. l and 3, is shown at A. The extreme edge ot` the lip has, of necessity, to be arranged at so short a distance, a b, from the edges a a of the sole S as to render it very difficult to linish the edge thereof.
In making our improved channel, which is shown at C in Figs. 2 and 4, we form it with two lips t 7c, to meet together directly or about over the axis ofthe channel, such channel being elliptical, circular, or ot'other proper shape in its cross-section. Thus the passage from thechannel, when the channel is open, as shown in Fig. 4, leads vertically out ot' it', and there is a much greater space between thejunction et' the lips and the adjacent edge ot' the sole when the lips are in contact than exists between the edge a a and the single lip B when the channel is provided with a single lip and seat thereto, in manner as heretofore practiced, or as exhibited in Figs. l and 3, the channel in each case being supposed to be arranged at the same distance from the edge ot' the. sole.
With our improvement the accidental raising ot' either ot' the lips is not so likely to occuras with the single-lip channel, and` besides, the edges otl the sole can be finished to much better advantage and with less cost and care.
We do not claim the channel formed with t-he single lip and a seat therefor, substantially in the manner as represented in Figs. l and 3.
We claim- Our improved channel C, as made with the two lips i 7.1, arranged so as, when closed, to meet together directly over the channel, substantially as hereinbetore described, and as represented in the remaining figures ofthe said drawings.
