HOLDIDOWN FOR LASTING-MACHINES.

Specification of Letters Patent.

Patented Mar. 13, 191?.

7 Application filed May 26, 1913. Serial No. 769,954.

To all whom it may concern:

Be it known that I, Lnwis H. LARSEN, a citizen of the United States, residing at Racine, in the county of Racine and State of lVisconsin, have invented certain improve ments in Holddowns for Lasting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to lasting machines and particularly to means for holding the work in bed lasting machines.

In lasting shoes upon the commercial bed lasting machines, it is necessary that the shoe be held down firmly upon the toe rest and it is important that the innersole be firmly held at and adjacen't to the channel lip at and around the end of the toe because while the upper is being wiped over the edge of the last and over the feather of the innersole the innersole tends to crumple up at the channel or the rib line, or even to be displaced bodily unless it is securely held against such action. The difficulty from crumpling of the innersole has seriously increased within the past few years during which the great advance in the price of leather has obliged manufacturers, in order to hop as near as possible to the former nmnufacturing cost, to use a thinner innersole or one which is of less firm quality, it having been found that such an innersolr will give good satisfaction provided the shoe is properly lasted and welted.

In addition to the difficulties arising from the crumpling up of the innersole at the channel and the consequent displacement of the lip which determines the stitching line by which the welt is attached around the toe, the use of these thinner and more flexible innersoles greatly increases, as would be expected, the liability that the lip or rib will be bent inwardly or overridden in lasting the toe of the shoe so that the upper materials lie upon it and render uncertain or impossible the proper stitching of the upper materials and welt to it. This difliculty is increased by the present use of bulky fabric toe stiffening material in place of the thinner but more expensive sole leather stiffeners.

For these reasons it has become increasingly important to provide a continuous support or abutment for the inner face of the channel lip at the tip of the toe and in order to serve its purpose adequately this support or abutment must extend backwardly a considerable distance on one or both sides of the toe but particularly on the outer side of the toe Where is found the swing that characterizes distinctively right and left lasts. The best results in lasting toes are obtained, as I have found, by the use of a continuous or substantially uninterrupted abutment for the inner face of the channel lip around the toe, said abutment having an edge contour to lit the innersole accurately inside the lip and constituting in eflect an inside former between which and the lasting plates as outside formers the upper and stiffener materials are molded and compressed into an upstanding flange against the channel lip. By so lasting the toe it is easy to sew it in the welting operation and, moreover, the inseam or line of attachment of the welt is accurately located where the designer of the shoe intended it should be and the appearance of the shoe is not adversely affected by a distorted inseam at the toe. Furthermore, since the toes of modern right and left lasts are not symmetrical with respect to the longitudinal'median line, it becomes necessary in order that the lip of the innersole shall be properly supported that the shape of the means for supporting the lip of a right toe shall be the reverse of the shape of the means for supporting the lip of a left toe. Therefore for the best results a pressing member must have two pressing faces, one conforming to a right toe and one conforming to a left toe.

It is the object of the present invention to provide a hold-down device which will answer to the requirements of the trade conditions as above outlined and preferably to provide a hold-down device having two of the channel lip at the end of the toe and along one and preferably both sides of the toe and having a substantially continuous.

or uninterrupted face forming an abutment for the inner face of the lip at the tip of the toe and along one and preferably both sides of the toe as and for the purpose stated. Preferably the abutting face for the lip will extend substantially to or above the top of the lip to hold the upper portion of the lip against the pressure of the lasting plates that are located on top of the overwiped upper.

A further feature of this invention is a hold-down device comprising an arm movable over a shoe supported by a lasting machine, and a pressing member carried by said arm and having two pressing faces, one conforming to the toe portion of a right sole and the other conforming to the toe portion of a left sole, said member being adjustable relatively to the arm to make either pressing face operative or, in other 'words, to make the said faces interchangeably operative.

A further feature of this invention is a hold-down device comprising a pressing member and mountings therefor which member has formed on its upper and lower faces respectively two pressing faces of the character above described for use with right and left shoes, said mountings permitting detachment and inversion of the pressing member and re-attachment thereof to render operative either its pressing faces for a right shoe or its pressing faces for a left shoe. As I am advised it is new by this invention to provide a rightand left holddown device which is invertible to render a pressing face that is on one side of it operative for a right shoe and a pressing face that is on its opposite side operative for use on a left shoe.

A further feature of this invention consists in the provision for lateral angular adjustment of such a pressing member as described about an axis located near its rear end for adapting each pressing face to form the described abutment, extending along the sides and particularly the outer sides of the toe, for the channel lips of slightly different contours of right or left toes.

These and other features of the invention will app-ear more fully from the following detailed description when taken in connection with the accompanying drawings and will then be definitely pointed out in the claims.

Figure 1 is a perspective view of a hold- Ll( \\'1'1 1110l12111l8111 embodying my invention and a portion of the toe head of a lasting machine Figs. 2 detached show the and 3 show the hold-down device from the transverse carrier and pressing member adprsted respectively for a left toe and for a right toe;said member fitting in each instance against the inner face of the lip of the innersole;

Fig. l is a sectional view on the line 4c-'-l of Fig. 2;

Fig. 5 is a view of the lower face of a modified form of the hold-down foot.

At A is shown the forward portion of a toe lasting head of the commercial type of bed lasting machine, such, for example, as

that shown in U. S. LettersPatent to Brock No. 1,018,4l77, granted Feb. 27, 1912. At B is shown a toe rest which sustains the toe portion of a shoe during the lasting operation. The operating mechanism for the hold-down is substantially similar to that disclosed and fully described in the application of Keyes, Ser. No. 580,4100, to which reference may be had for details not herein given. The post 2 is mounted for vertical movement by means of a treadle not shown. The head 6 is mounted for rotation on the post 2 and supports a carrier 8 mounted to slide therein transversely of the shoe and having friction means for holding it in any position of adjustment. The inner end of the support 8 carries a headed stud upon which is detachably held a finger or arm 10 by means of a slot 12 provided for the purpose. of ashoe supported in the lasting machine and is provided with a depending stud 1% in the rear of which is a bolt hole. A holddown plate or pressing member 16 is provided with a hole 18 to fit the stud 1 1 and with a hole 20 which is located to aline with the bolt hole in the arm and is countersunk on both sides. For holding the pressing member 16 securely to the arm 10 a stove bolt 22 is provided, the head of which enters the countersunk hole 20 and the body of which passes through the hole in the arm 10 and is held by a nut 24, Fig. fl:- The pressing member 16 has a pressing face to engage down upon the innersole and said member is contoured to provide for so clamping the innersole at and adjacent to the base of the channel lip at the tip of the toe and along each side of the toe backwardly for a substantial distance, as shown in Figs. 2 and 3. By so clamping the innersole to the last at the base of the channel lip I successfully prevent very thin and flexible innersoles from crumpling or buckling up at the channel. The pressing member also has an edge face 26 of sufficient height to extend substantially to, and it may be above, the top of the channel lip as in Fig. 4: to present an abutment between which and the lasting plates 27 the upper and toe stiffener 1 materials are compressed and molded into an upstanding flange in position for sewing together in the welt attaching operation. The pressing member is contoured to pre- The arm 10 extends toward the toe Hal sent, as shown in Fig. 2, said abutment 26 133 in a continuous or uninterrupted line parallel to and in supporting contact with the inner face of the channel lip at the tip of the toe and along both sides of the toe back about as far as the upper materials will be failed in wiping them over the concave edge of the toe of a left shoe.

The upper side, Fig. 2, of the member 16 is adapted to serve as a pressing face for a right shoe when said member is inverted as in Fig. 3 and from the construction described it will be evident that by removing the bolt 22 said member 16 may be slipped off of the stud 11, inverted and replaced upon the stud the other side up, in which position it may be again secured to the arm by replacing the bolt and nut, 22, 24:-

By this construction is provided an invertible presser member having on its upper and lower sides respectively pressing faces shaped to fit difi'erent shoes, as for example one face conforming to thetoe portion of a right shoe and the other face conforming to the toe portion of a left shoe, and means for holding said member to its carrying arm 10 with either pressing face disposed clownwardly in shoe engaging position whereby said faces may be made interchangeably operative.

In Fig. 5 the pressing member 16 is formed, as for example with two holes 18, 15), to cooperate with the stud 1A in different positions of adjustment whereby said pressing member may be made to conform to slightly different widths or to somewhat varying styles of shoes, this pressing member being preferably invertible for use with both rights and lefts.

The stud 14L on the arm 10 and the hole 18 Or 19 in theplate 16 constitute what are herein termed coupling members which, with the assistance of thebolt and nut 22, 2a which retain the coupling members in operative engagement, are adapted to secure the plate 16 to the arm 10 with either side facing the sole of the shoe.
