FOLDING-MACHINE Application filed February 7, 1916.

To all whom it may concern:

Be it known that I, JAMES E. MCINTIRE, a citizen of the United States, residing at Weymouth, in the county of Norfolk and State of Massachusetts, have invented certain Improvements in F olding-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 folding machines and is herein illustrated in connection with a machine for folding a binding strip over the edge of a piece of upper material for use in the manufacture of boots and shoes.

For convenience of description the upper material will be referred'to as a piece of leather and the binding-as a strip of fabric.

It is customary in the manufacture of certain styles of shoes to stitch to a piece of the upper, for example a vamp, a strip of fabric, apply cement to said fabric and then fold the fabric over the leather to form a binding. Hitherto the folding has been done by hand; .and the general object of the present invention is to provide mechanism for performing this folding operation.

According to one feature of the invention a gage extends into the junction of the leather or other material with the binding at a point at which the work is unfolded. There is thus provided proper means for guiding the work as it is fed to the folding mechanism.

This and other features of the invention, including-certain details of construction and combinations of parts will be described in connection with an illustrative machine'and pointed out in the appended claims.

Referring to the accompanying draw- 1ngs,

Figure 1 is a perspective of a portion of a machine in which the present invention is embodied, showing a piece of work in process of being folded;

Fig. 2 is a detail perspective on an enlarged scale of the folding and pressing instrumentalities v Fig. 3 is a perspective of the effective end of the edge gage and the preliminary turning member;

Serial No. 76,666.

to which a fabric binding strip has been stitched, and

Fig. 5 is a similar View showing the binding turned back ready to be folded.

The invention has been illustrated in connection with a machine of the type shown and described in British Patent No.'l9,937 of 1914. In the illustrative machine, as in the machine of the patent, the work 100 is fed intermittently over -a support 1, and the margin of the work is progressively folded over the end of a creaser 3 by a folder or folding finger 5 which is continuously reciprocated to turn the margin of the work progressively over the-end of the creaser after the manner shown in Figs. 1 and 2. The oscillating presser or hammer 7 acts to press the fold as indicated in Fig. 2, and serves also, in connection with a'movable anvil (not shown) to feed the work. The movement of the presser is as follows:

Starting with the raised position shown in Fig. 1, it descends tothe position shown in Fig. 2 in which it presses the folded margin upon the anvil. The hammer and anvil then move in unison to the left as viewed in Fig. 2 to feed the work, after which the hammer rises and then both hammer and anvil return to the starting position. In order to facilitate the feeding of the work, the hammer or presser 7 has fastened to it a resilient finger 10 the operative end of which extel'ids toward the creaser 3 and engages the work at a point removed from the edge thereof. As thus far described, the illustrative machine is substantially identical with that of the British patent and no further detailed description of it will be given.

The machine of the patent is adapted to fold the skived margin of a piece of leather. In the present case, however, the leather is neither skived nor folded. Referring to Fig. 4, there is shown a portion of a shoe upper, for example a quarter, to which has been stitched at 9 a strip of fabric 11 which is later to serve as a binding for the edge of the leather. After having been stitched in place the binding is cemented and turned back into the position shown in Fig. 5. The leather part with the cemented binding is then placed upon the support 1 (see Fig. 1) with the cemented side of the binding uppermost and presented tothe feeding and folding mechamsm. In order to guide the work a gage 13 pivoted at 15'to a stationary part is normally pressed down upon the flat top .of a preliminary turning member 17 by a spring 19 and is provided at its rear end with aflat projection 113 pressure upon which by a finger of the operator will raise the operative end of the gage to permit prcs entationof the work. The operative end 213 of the age extends downwardly into the corner ormed at the junction of the leather with the fabric and engages the edge of the leather thereby serving to guide the Work as it is fed. Although in the illustrative machine a preliminary turning member is shown the turning function of this member is not essential, its principal func tion being to receive on its flattop the stem of the edge gage 13 and thereby to prevent the operative end 113 of said gage from pressing with any considerable force upon the binding.

Although the invention has been set forth in connection with a machine having a movable folder, a stationary creaser, and a combined feeding and fold pressing mechanism,

it should be understood that this has been done to promote brevity and clearness and that the invention is not limited in the scope of its application to the particular throughout its length having, in combination, means for feeding the work, a gage arranged to engage an unfolded portion of the work at a distance from the edge there 'of, and means located entirely in the rear of the gage for folding the binding over they edge of the material.

- 2. A machine for folding a piece of work which consists of a piece of material to which a stri of binding has been attached throughout 1ts length, having, in combination, means for feeding the work,- a gage arranged to extend into the corner at the junction of the material with the binding at a point at which the work is unfolded, and means for foldin the binding about the edge of the material.

3. A machine for folding a piece of work which consists of a piece of material to which a strip of binding has been attached throughout its length, having, in combina tion, a gage arranged to extend into the corner formed by the attachment of the binding to the material, and means for folding the binding about the edge of the material.

4. A machine for operating upon a piece of work which consists of a piece of material material and the binding, a creaser the operative portion of which is located close to the edge of the material, a folder for turning the binding over the creaser, and a presser to press the binding upon the material.

5. A machine for operating upon a piece of work which consists of a body material to which a more flexible strip has been attached throughout its length, said material and strip being so related that at their juncture the edge of the material forms a shoulder, comprising means for guiding the work by engagement with the shoulder at an unfolded portion of the work, and means for progressively folding the strip over the material.

6. A machine for folding over the edge of a piece of leather a piece of fabric which is attached to the margin of said leather, having, in combination, means for feeding the work intermittently into position to be operated upon, an edge gage extending over the unfolded fabric and into engagement with the'edge of the leather, and folding and pressing mechanisms located in the rear of said edge gage.

7. A machine for folding over the edge of a piece of leather a piece of fabric Which has been attached throughout its length to the margin of said leather, having, in combination, an edge gage extending overthe unfolded fabric into engagement with the edge of the leather, means for feeding the work past the gage, and means for folding the fabric over the leather and pressing it into place.

8. Mechanism for feeding and guiding a piece of work which consists of a piece of material to which a second piece of material has been attached throughout its length, comprising'a bed for supporting the work, a gage arranged to extend into the corner at the junction of the two pieces of material, said gage being located above the face of one of the pieces in position to en 'gage an edge of the other, and means for JAMES E. MoINTIRE.
