FREDERICK.M. FURBER, 0F REVERE, MASSACHUSETTS, ASSIGNO-R T0 UNITED SHOE MACHINERY COMPANY, OF PATTERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

To all whom it may concern:

Be it known that LFRE ERICK M. FURBER, a citizen of the United States, residing at Rev-ere, in the county of. Suffolk and State of Massachusetts, have invented-certain Improvements in Welt-Laying Machines, of which the followingdescription, in connection with the accompanying drawings, is a specification, like reference characters on the drawingsindicating like parts in the'several figures. I

Thls lnventlon relates to mach nes for laying welts, rands and similar strips and isherein illustrated in connection with a welt" laying machine of the general type shown in United States patent to McLeod No. 957,987.

In the manufacture of shoes, particularly those known asMfcKay, it is sometimes the practice to provide a mockor imitation welt on the margin of the upper surface of the sole in order to give the" shoes an appearance moredesirable'to the trade. Hitherto it has been customary to prepare the welt,'for example, by notching one edge of it as shown in United States patent to Arnold No. 646,592, sothat theweltmayiconform readily to thecurvature of the edge of the sole and may be laid fiat without the formation of folds or puckers which would otherwise occur, particularly aroundthe toe portion of the sole.

The general object of the present invention is to provide a machine by which a plain welt may be smoothly laid and thereby to do away with the necessity which has heretofore existed for slitting, notching' or similarly operating upon the inside edge of the welt prior to using it in a welt laying machine. I I

One' feature of the invention comprises, in a machineof the class described, means for applying a welt to a sole and means for removing during the laying operation the puckers which form where the welt is bent or turned. I This and other features of the inventionincluding certain details of construction and combinations of parts will be described in connection with an illustrative machine and pointed out inthe appended Referring now to the accompanying drawings,'"Figure 1 is a front elevation of a Specification of Letters Patent.

WELT-LAYING MACHINE.

tion of the sole; Fig. 3 is a perspective.

similar to Fig. 2 butshowing a knife in place of the pounder.

Mounted in fixed bearings in the frame of the machine is a shaft 1 to the outer end of which is fast a feed wheel 3 and to the inner end a gear 5 said latter gear being rotated througha gear 7 by a so-called handbelt-power drive,? the details of which are not shown since they form no part of the present invention. It will be suflicient to point out that the gear 7 is rigid with a friction disk 9, that the continuously driven pulley 11 is loose on the stud 13, that said pulley has a friction face adapted to cooperate with the adjacent face of the friction disk, and that by turning the handle 15 the pulley may be forced against the disk with a controllable amount of pressure, the pull of the driven belt 17 aiding the operator.

The gear 5 meshes with a gear 19 fast to a hollow shaft 21' upon the outer end of which the laying wheel 23 is fast, said holmachine and is urged downwardly about;

said pivot by. a spring 29. A screw bolt 31 determines the lower limit of movement of the casting 25 and hence of the laying wheel 23, and a treadle rod 33 provides means to lift the wheel 23 when desired to facilitate the insertion of the work. An edge gage 35 and welt guide 37 insure that the welt shall be laid along the edge of the sole. The machine, as thus far described, is similar to the machine of the McLeod patent and its details of construction will not be further described.

Extending through the hollow shaft 21 is a solid shaft 39 to the outer end of which is fast a pucker-removing and welt-smoothing tool 41 herein shown as a pounder having a,

pulley 43 which may be driven continuously in any suitable manner one face of said Patented Decl), 1916. Application filed May29, 1915. SerialNo. 31,180. v i i pulley being held against a roll 45, the axis of which is fixed, by a coiled spring 47, said spring being located between a collar 49 on the shaft 39 and a shoulder on the hollow shaft 21. That face of the pulley 43 which contacts with the roll 45 is provided with depressions one of which is shown at 51 with the result that the shaft 39 and pounder 41 are reciprocated as they are rotated. A shield 53 partially incloses the wheel 23 and pounder 41 to protect the operator from possible injury.

In the operation of the machine the end of a piece of welting, which is supplied in a coil and mounted near the machine on a reel (not shown), is drawn through the guide 37 and laid on the margin of a sole. The treadle rod 33 is then moved downwardly to separate the wheels 23 and 3, the sole and welt pushed between the wheels, and the treadle rod released. The operator then turns the crank 15 with one hand and guides the sole with the other. As the sharply curved toe portion of the sole is reached, puckers form or start to form in the inside edge of the welt; and these puckers are removed and the welt smoothed and beaten down by the pounder 41, the combined reciprocatory and rotatory movement of the pounder facilitating this desirable I result. The direction of rotation, of the pounder is opposite to that of the wheel 23 so that a more effectively smoothing action on the welt is secured than would otherwise be the case.

In Fig. 2 a modified form of tool 53 for removing the puckers is shown, said tool being a pounder of general elliptical outline, the plane of the ellipse being inclined obliquely to the axis of the shafts 21 and 39.

In Fig. 3 the tool for removing the puckers is shown as a knife of a generally cylindrical shape, having two semicircular blades 55 the height of'each of which in creases gradually from its forward end (with reference to the direction of rotation) to its rear end. In the figure the arrow indicates the direction of rotation of the knife, and it will be seen that the effect is to shave off the puckers as fast as they are formed or start to form whereas, when the pounders are used, the puckers are beaten down fiat.

It should be noted that all three tools have a rubbing action on the welt and act to smooth the welt as well as to remove the puckers or prevent their formation. It should be understood that the welting is usually skived so as to present a thin inner edge and that the face of the welting which is to contact with the sole carries a coating of cement so that the welt, when laid, will adhere to the sole.

Although the invention has been described in connection with a machine for laying a welt on a sole it should be understood that the invention is not limited in the scope of its application to the particular machine shown and described.

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