MACl-HNE FOR TURNING THE CHANNEL-LIPS OF INSOLES.

SPECIFICATION forming part of Letters Patent No. 388,280, dated August 21, 1888.

Application filed January 24, 1888. Serial No. 261,737.

To all whom it may concern:

Be it known that LSAMUEL H. HOWLAND,Of the city and countyof New York, in the State of New York, have invented a certain new and Improved Lip-Turning Machine for Treating Insoles of Boots and Shoes, of which the following is a specification.

It is common to cut by hand or by machinery around the edge of an insole,-so as to split the edge of the leather or divide it into two nearly equal thicknesses, leaving one portionthat next to the foot-sm0oth and unaffected, and to turn up the other portion. This is usually done with the leather in a dampened and limbered condition, and no harm results if the turning,instead of being arrested in an upright condition, is carried further, so as to fold the lip over upon the unsplit portion within it. My improved machine is intended to effect this rapidly and perfectly.

I provide a beveled guide, which, as the in sole, after being properly split around the edge, is presented to it, insinuates itself into the cut and lifts the lip. I provide a reciprocating jaw, which next takes hold of the lip and turns U it ovcrand presses itdown upon the unaffected portion of the insole. I provide two guides, one on each side of the reciprocatingjaw. These hold the work better in position and allow the operator to move the sole in either direction-that is, to the right or to the left. The jaw reciprocates actively, and by moving the insole by hand or machinery the entire lip is rapidly turned over and pressed down by the successive compressions of thejaw. I provide adjustments which regulate the position of the guides and of the base or support on which the insole rests, adapting it to greater or less thicknesses. I introduce a spring to regulate the action and allow it to yield to temporary inequalities.

The invention applies more especially to the manufacture of what are known as imitation hand'sewcd shoes.

The accompanying drawings form a part of this specification, and represent what I consider the best means of carrying out the invention.

spending parts in all the figures where they occur.

The bcd-casting A is bolted down upon a work-bench or other suitable support. (Not shown.)

B is a shaft rotated by a belt from any convenient power, running on a pulley, B. An eccentric, B", fixed on shaftB takes hold by an eccentric-strap, D,of a rod, D, equipped with nuts D D, a spring, E, and bearing-washers E, which engage with the upper arn1,G,of-a bellcrank lever, the lower arm, G, of which lever is the w0rking-jaw,which performs the function of pressing down the lip.

M is the insole, M the unaffected portion of the edge, and M the lip which it is desired to turn over. The hub or center G of the lever G G is held by stout pivots A A, tapped through lugs in the bed and adjusted by jamnuts A.

I is a casting held adjustably on the front face of the bed A, being steadied by vertical guides A at each side. Its upper end is dividcd, forming two guides, I I", which stand on opposite sides of the jaw G.

An adjustable slide, J, held on the front face of casting I and steadied on the latter by vertical guides J at each side, carries a table, J which presents a flat upper surface at adj ustable heights under the guides Iand Iand the Vertical reciprocatingjaw G The slides I and Jare both firmly held by a single bolt,K, inserted through the slots in the slides and tapped into the bed A. The lower edges of the guides I I are beveled, as shown.

In the use of the machine the lip of the properly cut and dampened sole is first raised at one end by the finger or otherwise, and the sole is laid upon the table J and its edge M thrust under the guides I l, and the reciprocating jaw G commences to press down on such portion of the lip M" as is presented thereto. Now, by moving the sole laterally to the right or theleft, keeping its edge M under the guides I I successive portions of the lip as they are presented are lifted by the guides and turned over and pressed down by the jaw G. Thus the sole may be moved in either direction until the entire lip llP, commencing at one end, may be folded over and pressed down in the open position throughout its entire length.

The operation is rapid and efficient. It re quires but little skill, If a thicker lot of insoles are to be treated,the bolt'K is slackened and the table J is lowered and again secured. The piece I, with its guides I 1 may also be raised and lowered to adjust their position relatively to the table J or to thejaw Gflor to both.

When any temporary increase of thickness is presented, the spring E yields and allows the jaw G to be arrested in a higherposition, thus accommodating inequalities in the work.

The position in which the lever G G ordinarily acts may be varied by shifting the nuts D D outward or inward on the rod D. The tension ofthe spring E may be varied by setting the nut D backward or forward on the rod D. There may be ajam-nut behind each of the nuts D and D to aid in maintaining themin position. I have shown ajam-nut,D", behind the nut D The holethrough the arm G,which receives the operating-rod D, is doubletapered, as shown, and the bcaringsurfaces by which the nuts take hold on the arm G are spheroidal, and the inner faces of the bearing-washers E are correspondingly spheroidal, thus accommodating the bearing to all positions of the lever.

O is a loose pulley, performing the usual functions of such member.

Modifications may be made without departing from the principle or sacrificing the advantages of the invention.

Other means may be provided for holding and adjusting the position of the table J and of the guides I I Parts of the invention may be used without the whole. I can dispense with the guide I and operate only with the guide I, always moving the sole from the left to the right. I prefer the whole, as shown.

I claim as my invention 1. In a machine for turning the channel-lips of insoles,the beyeled guide I and table J, in combination with each other and with thejaw G reciprocated relatively to the table,adapted to turn over and press down the lip of an insole, substantially as and for the purposes herein specified.

2. In combination with the guide I, table J and reciprocatingjaw G the spring-Ecccentric B, and rod D, arranged to operate the jaw with a yielding force, as herein specified.

3. The duplicate guides I P, in combination wit-h the reciprocating jaw G, table J and means, K, for adjusting the guides and table,

arranged to serve substantially as herein speci fied.

In testimony whereof I have hereunto set my hand, at New York city, this 21st day of Jannary, 1888, in the presence of two subscribing witnesses.
