SPECIFICATION forming part of Letters Patent No. 671,397, dated Apr12, 190i.

Application tiled July 27, 1900. Serial No. 24,990. (No model.)

To @ZZ whom it may concern.:

Be it known that I, MICHAEL H. LYONS, a citizen of the United States, residing at East Bridgewater, county of Plymouth, State of Massachusetts, have invented an Improvement in Welt-Laying Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing 1o like parts.

This invention has for its object the production of a novel machine for laying upon the inner side of an outer sole a welt, the welt being joined to said sole by cement of some suitable form. Preferably the welt will be notched, as a notched welt may be more readily bent to adapt its outer or thicker edge tothe congnration of the sole and especially when the welt is being applied to rounded portions of the sole. Heretofore welts have been laid upon a sole by a hand operation, which is a slow and laborious process, and by the employment of the machine herein to be described the welts may be laid with great rapidity and with greater accuracy.

My improved machine consists, essentially, of a support for the face of the sole, a weltguide to present the welt, a Welt-presser or device to insure close contact of the under side of the welt with the sole, and an edgegage against which the outer or thick edge of the welt may run. For the best results the face of this edge-gage will be curved at that part thereof against which the outer edge of 35 the welt being laid first contacts, and this gage will also preferably act to guide both the welt and the edge of the sole. The welt-guide, which receives and controls the welt, is solocated With relation to the upper side of the support and the acting face of the edge-gage that the welt approaches the sole diagonally and meets the sole substantially in the line of pressure between the support and the presser or device which acts upon the upper side of the welt, the angular presentation of the welt being of very material advantage, for if the welt should contact with the sole materially in advance of the line of pressure referred to difficulty would be experienced in thereafter sliding the Welt on the sole laterally when adapting the welt to the contour of the sole. It Will be remembered that the welt will preferably be coated with cement before it is applied to the sole, and the cemented welt will preferably be moist-end to soften or make active the cement, that it may adhere properly to the sole, the compression between the presser and support of the sole and welt causing the welt to adhere firmly to the sole.

Figure l, in side elevation, represents a suf- 6o ficient portion of a machine embodying my invention to enable the same to be understood, the sole and welt being represented in position, the sole being in section. Fig. 2 is a detail plan view below the dotted line Fig. l, chiefly to show the welt-guide and the gage for the edge of the welt and the sole. Fig. is a detail showing part of the machine looking at it from the left, Fig. l; and Fig. 4 is a section in the line at', Fig. 2.

The column A, adapted to stand on a bench or door, has suitable uprights A A2, in which are mounted suitable bearings for a shaft B, having secured to its front end a sole-support B, represented as a wheel or disk. The

rear end of this shaft has connected with it a large toothed gear B2, which is engaged and driven from atoothed gear B3, fast on a sleeve B4, having connected with it a belt-pulley B5, which when rotated rotates the shaft B. The 8o shaft B has a connected toothed pinion C, which engages a second pinion C', fast on a shaft C2, mounted at its rear end in a pivotal bearing C3, located between the nprights A. The front end of the shaft C2 has a presser 85 D, which acts directly upon the upper side of the welt a, said presser being herein represented in the form of a roller. The shaft C2 nearits front end is free to rotate in a bearing C4, which is normally depressed by 9o or through a cam C5, pivoted at C6 in a stand l2, attached to the upper ends of the uprights A2 by means of suitable screws 13, the cam being acted upon by a spring 14, connected therewith, the spring having attached to its lower end a suitable threaded rod l5, extended through a bearing 16 and having applied to it a nut 17, the adjustment of the nut varying the pressure of the cam upon the bearing.

Whenever the work is to be removed or the roo pressure device is to be raised, the cam 'C5 will be turned by or through a link C7, connected at its lower end with a suitable treadle. A suitable spring b acts when permitted to lift the bearing O4 and release the contact of the presser D from the Welt.

At the front of the machine I have connected to the uprights A2 by suitable screws b' a stand ct,havinga shoulder 01,2,which serves as a guide for the inner or serrated edge of the welt a, the opposite outer or straight edge of the welt being acted upon by a lip a3, forming part of an adjustable cap or cover a, connected with the stand a by a suitablescrew a5. (See Fig. 4.) By loosening this screw the cap a4 may be adjusted to receive under it a welt of any Width. This guide is located (see Figs. l and 3) above the horizontal plane in which the upper edge of the support rotates, and saidguide is also located at the right-hand side of the edge-gage d, so that the welt will approach the straight portion d of the edgegage at an angle both downwardly and laterally.

The location of the welt-guide above the sole-support and the surface of the sole sustained thereon enables the cemented Welt to f contact with the sole substantially in the vertical line of pressure of the support and presser, and by locating the guide at one side of the line of travel of the shoe, as represented in 2, and by rounding the edge d2 of the edge-gage it is possible to cause the welt to be bent in the direction of its width, especially when the vwelt is being laid with its outer edge against an incurved portion of the sole, as in the shank. The straight part of the edge d serves not only to guide and position the edge of the Welt, but also the edge of the sole, so that the outer edge of the welt and the edge of the sole are correctly alined.

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

1. In a welt-laying machine,a sole-support,

a presser or device to act on the outer side of the welt, a welt-guide, and a gage for the outer edge of the welt and sole, that part of the face of the gage against which the welt first strikes on its way to the sole being curved ,ito enable the welt to be bent and laid on the ,sole to conform with the shape of the edge thereof.

2. In a Welt-laying machine,a sole-support, ia presser to act on the outer side of the welt, a welt-guide, and a gage for the outer sole and welt, said gage having its face next the fwelt-guide curved, and its face farthest from the said guide substantially at right angles to the longitudinal axis of the shaft carrying Lthe sole-support. g

3. In a welt-laying machine, a sole-support, and presser, and edge-gage, combined with a gwelt-guide located above the point of contact of the support and presser withv the sole and -lwelt that the under side of the Welt may be presented to the sole substantially in a verfjtical line intersecting the axis of rotation of @the support and the presser.

4. In a welt-laying machine, a sole-support, fa presser to act on the welt as it meets the sole, a welt-gage to aline the edge of the sole and welt and curved to support the edge of the welt and enable it to be bent in the diirection of its Width when beinglaid about an 1incurved part of the sole, and a guide for said welt, said guide being located above the upper side of the sole to enable the under side of the welt to contact with the sole substantially in'the line of pressure between` the support and presser. In testimony whereof I have signed. my name to this specification in the presence of 'two subscribing witnesses.

MICHAEL H. LYONS.
