To all whom it may concern:

Be it known that we, Josnrn J. MARsn and ARTHUR BATES, subjects of the King of England, residing at Leicester, in the county of Leicester, England, have invented certain Improvements in Machines for Operating Upon Boots or Shoes, 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 machines for operating upon boots or shoes, and particularly the invention relates to a machine for attaching welts which has especial utility in effecting the attachment of a welt or rand to the bottom face of a lasted boot or shoe.

The term welt as used hereinafter is in tended to include within the scope of its designation various articles having the general characteristics of a welt, although not necessarily its usual functions, such as rands, imitation welts, etc.

In certain classes of Work it has been the practice to attach a welt, usually by metallic fastenings, upon the marginal portion of a sole or upon the bottom face of a lasted shoe. As the welt is bent edgewise to conform it to the outline of the sole or bottom to which it is to be attached difficulty has been experienced in causing the welt to assume the out line of the part to which it is attached where this outline changes its direction abruptly, as for example, at the sharply curved portions of the outline about the toe part of the sole or shoe.

In the co-pending application of Arthur Bates and Thomas Briggs, Serial No. 505,601, filed July 2, 1909, for Letters Patent on improvements in machines for operating upon boots or shoes is disclosed a machine in which the difficulty above pointed out has been overcome by providing means controlled by the angular position of the work with respect to the welt attaching means for effecting a relative displacement of the welt and work as successive portions of the work are presented to the attaching means. It will be readily understood that a machine operating in this manner can handle a great variety of shoes as regards sizes and styles since the abruptly curved portions of the shoes of the different sizes and styles are in like angular relations to the axis about Specification of Letters Patent.

which the shoe is turned as the successive portions are presented to the attaching means. It is, however, frequently desirable to project the welt different distances at different selected or predetermined points throughoutits extent, particularly along the sides of a shoe, whereby the Welt may be made to conform approximately to the outline of soles having so-called extension edges, and an object of the present invention, therefore, is to provide in a machine of the type above referred to means for thus effecting different projections of the welt at difi'erent selected or predetermined points throughout its extent which has capacity for effecting such variable projection at points other than those which are in like angular relations in different shoes to theaxis about which the work is turned as it is presented to the attaching mechanism.

In the preferred embodiment of the invention the means for causing the variable projection of the welt is under the control of the operator in order that the machine may handle without adjustment a great variety of work. Moreover, the means for causing the variable projection is preferably combined with the means, such as disclosed in the co-pending application above referred to, for automatically insuring the required projection at the abruptly curved portions of the outline and is preferably arranged to act through said means or through a part of said means.

A preferred construction, according to the present invention, will now be described as applied to a loose nailing machine of wellknown type.

Reference may be had to the accompanying drawings in which,Figure 1 shows in side elevation the parts of the machine with which the invention is immediately associated; Fig. 2 is a section on the line 2-2 of Fig. 1; Fig. 3 is a front elevation of certain of the operative parts of the machine, the shoe being shown in section; Fig. 4: shows a modification of the gage and its removing means; and Fig. 5 shows a shoe to which the.

herein illustrated but not described. The machine of the said patent comprises a laterally swinging head which carries an awl 2 and a driver 4. Connected with the head to swing therewith is a raceway 6. The head is moved laterally after the awl has penetrated the work to feed the work andthenthe awl is retracted and the head returned to its original position to bring the driver 4 into alinement with the hole made 7 The nail is then discharged from the raceway 6 into the driver passage in the nose 8 from which it is driven by the driver into the hole formed for it in the work by the awl.

The machine is provided with a jack, preferably of the type disclosed in the application of R. F. McFeely, Serial No. 264,260,- filed June 8, 1905, for Letters Patent on improvements in jacks for shoe machines. This jack is rotatably carried by the jack post 10 which is mounted to reciprocate vertically in an upstanding portion 12 of the. machine frame 14. The jack post 10 may be raised and lowered by any suitable treadle operated mechanism (not shown) to present the shoe 16 in position to be operated upon or to move it out of such position.

Thejack has provision for enabling the shoe to be moved lengthwise and to be tipped about axes extending lengthwise and laterally of the shoe in order that parts of the shoe to which the welt is to be attached may be presented properly to the fastening inserting mechanism. A detailed description of the jack will not be attempted herein in view of its disclosure in the application above referred to, and in view of the fact that it will not be herein specifically claimed. It will be sufiicient to state that the carrier 18 for the last pin and saddle is provided with lateral grooves 20' which receive pivoted guides 22 carried in a yoke 24 arc-shaped upon its lower side and arranged to slide in an arc-shaped guideway in a block or hub 26 whereby the shoe may be tipped about its longitudinal axis as hereinbefore suggested. The rocking of the shoeabout transverse axes is limited by stops 28 and 30, the stop 30 being vertically adjustable.

The welt 32 passes through a guide 34 carried by a slide 36 adjustable in guides in the machine frame. While being attached to the shoe the welt extends between the foot plate or work abutment 38 of the machine and the shoe on the jack, as shown in Fig. 3. An auxiliary guide 40, fixed upon the machine frame, supports the free end of the welt and keeps it out of the way of the operator.

A gage or guide 42, shown as a frustoconical roller, is mounted upon the slide 44 which is movable toward and away from the shoe in a block 46 secured to the machine frame. The slide 44 has a pin-and-slot connection 48 with the block 46 to limit the extent of its sliding movement. To provide means for varying the extreme positions of the gage or guide 42 the block 46 is mounted to slide on a guide 50 attached to the machine frame, and can be secured in adjusted position on said guide by a screw 52 which passes through a slot in the block 46 and screws into the guide 50. The slide 44 is operatively connected with a cam 54 carried upon the block or hub 26 of the jack by means of a lever'56 pivoted at 58 upon the machine frame and abutting at its upper end against the rear end of said slide, the lower end of the lever 56 carrying a roller 60 that engages the said cam.

Vith the mechanism thus far described automatic relative displacement of the work and the welt during the attaching operation is effected To permit a relative displacement other than that effected automatically by the mechanism just described, means is provided for moving the slide 44 at the'will of the operator. This means comprises a vertically disposed rock-shaft 62 mounted in the bearings 64 and 66 in the machine frame, said rock-shaft having an arm 68 secured upon its upper end. The arm 68 is adapted to engage a roller 70 carried upon the rear side of the upper end of the lever 56. A second arm 7 2 upon the lower end of the rock-shaft 62 is coupled to a knee-operated lever 74, pivoted at 7 6 upon a stud carried by the machine frame. The limits of the angular movement of the rock-shaft 62 are adjustably determined by stops 78 and 80. These stops are in the form of collars clamped upon the rock-shaft 62 and having depending arms disposed one upon each side of a projection 82 which carries the bearing 66 of the rock-shaft.

In the operation of the machine the shoe 16 is placed upon the ack and the welt 32 is placed in the welt guide 34 and throughthe auxiliary guide 40. The jack is then elevated to clamp the welt between the footplate or abutment 38 and the marginal portion of the sole face of the shoe, and the edge gage or guide 42 bears against the up per of the shoe adjacent to the welt in the neighborhood of the shank or waist of the shoe. At this time the gage or guide 42 is in its extreme rearward position, which in practice is preferably determined by the pin-and-slot connection 48 of the slide 44 with the block 46 which supports the slide, although it will be understood that this position may be determined in other ways, as, for example, by the shape of the cam 54. The machine is started and fastenings or nails are driven through the welt and into the insole, thus attaching them together, the shoe being fed by the awl 2 between the successive nail driving operations. WVhen the junction between the waist or shank and the forepart of the shoe is reached, if an extension edge is desired the operator moves the knee-operated lever 74 and turns the rock-shaft 62 and arm 68, as far as is permitted by the engagement of the stop 78 with the projection 82 from the machine frame. This causes the arm 68 upon the upper end of the rock-shaft 62 to force the cam lever 56 and the gage slide 44 forward, so that the'shoe is moved transversely to the line of feed and also relatively to the welt guide 34 to cause the welt to project to a greater extent beyond the edge of the last. When the toe part of the shoe is reached the jack is rotated by the operator in order that the .welt may be attached along the said part and this rotation of the ack brings the cam 54 into engagement with the roller 60, if the cam is not so shaped that it constantly engages said roller, thereby moving the lever 56'and through it'the slide 44 which supports the gage or guide 42. The gage 42 is thus forced forward still further in the machine, the operator maintaining the knee lever 74 in the position into which he has first moved it. This further movement of the gage 42 effects the relative displacement of the shoe and the welt to insure the proper projection of the welt at the points of abrupt curvature in the outline of the bottom edge.

Continued rotation of the jack removes the cam 54 from engagement with the roller 60 and the lever 56 and permits the gage 42 to be returned either by pressure of the work against it or by the action of a spring or the like into a position which is determined by the engagement of the arm 68 on the rock-shaft 62 with the upper end of the cam lever 56. By this time the welt will have been attached around the toe part of the shoe. The welt is next secured to the other side of the forepart and when the junction of the waist or shank therewith is reached the operator swings the knee lever in a direction reverse to that in which he swung it previously, thus permitting the gage 42 to return to its extreme rearward position determined either by the stop 80 upon the rock-shaft 62 or by the engagement of the pin in the slide 44 with the end of the slot in the supporting block 46.

It will readily be seen that with the foregoing construction various kinds of extension edges may be obtained and that the invention is not limited to the specifically described use. If desired the gage slide 44, instead of being carried in the adjustable block 46, may be mounted directly in the guideway formed in the machine frame or in a bracket 83 attached to said frame and may have adjustable engagement with the cam lever 56 by a screw 84 threaded through said lever and abutting against the rear end of the slide. This modification is illustrated in Fig. 4 and in this figure the slide is indicated at 86. An adjustable stop 88 extending into the path of the bearing 90 for the frusto-conical roller 42 limits the rearward movement of the slide 86.

Having described our invention, what we claim as new and desire to secure by Letters Patent of the United States, is

1. A machine of the class described, having in combination, means for attaching a Welt to work, means for efiecting automatically during the attaching operation a relative displacement of the work and welt at predetermined points in the line of attachment, and means under the control of the operator with respect both to the time of operation and to the amount of movement for effecting a relative displacement of the welt and work at other points in the line of attachment. 7

2.
