INSOLE-REINFORGING- MACHINE.

Specification of Letters Patent.

Patented June 15, 1915.

Application filed October 21, 1914. Serial No. 867,761.

To all whom it may concern Be it known that I, ALEXANDER M. Ann ANDER, a citizen of theUnited States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in In sole-Reinforcing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for applying reinforcing fabric to lipped insoles and more particularly to devices in such machines for trimming the fabric to the contour of the insole.

From the time that reinforcedinsoles of the Gem type, wherein the fabric is beaded or crimped about the lip, were first introduced, and until recently, it has been the practice to trim the fabricalong a line coinciding with the edge of the insole. It has long been recognized that the raveled threads showing beyond the edge of theinsole are undesirable as they renderthe sole unsightly and detract from its selling qualities. Various experiments have been made to avoid the trouble with the result that it is now coming to be the general practice to trim the fabric, particularly at the shank,

along a line spaced from the edge of the in-v sole, that is, the fabric is trimmed inside of the insole edge instead of at its edge.

The object of the present invention is to provide novel means for trimming the fabric so as to prevent the fabric on reinforced insoles from being seen when viewing the insole from its grain, or unreinforced, side. In accordance with this object the invention contemplates the provision, in a machine of the character described, of a knife located above the/feather and within its edge, in combination with means beneath the fabric for supporting it so that it may be cleanly severed by the knife and for also preventing a slitting of the'feather, which would weaken the insole. To the accomplishmentof this object, the invention comprises the features. and combinations of parts hereinafter described and particularly defined in the appended claims.

The features of the invention will be best understood from a description of the preferred embodiment thereof illustratedin the accompanying drawings, in which the inaway patent is retained,

vention has been shown as applied to the insole reinforcing machine exemplified by Letters Patent of the United States to John B. Hadaway, No. 614,860, dated November 29, 1898. r

In the drawings, Figure l is a side elevation of the machine; Fig. 2 is a detail illustrating the mounting of the fabric trimming knife, and the resultant efiect on an insole; Fig. 3 is an underside view of the knife and its cooperating plate; and Fig. & is an enlarged detail illustrating the manner in which the knife cooperates with a slotted plate to shear the fabric.

The tools for supporting, feeding and forming the bead or crimp in the reinforcing fabric and applying it to the insole, that is, the work table 1 and its step-by-step feeding mechanism; the inside and outside forming tools 2 and 8 respectively and their operating mechanisms; and the anvil or former 4, which also by its engagement with the lip performs the function of a gage to determine the position of the insole in the machine, may be, and preferably are, substantially the same as the corresponding parts in the Letters Patent to John B. Hadaway hereinafter referred to, to which patent reference may be had for a detailed description thereof.

Referring now to the novel fabric trimming mechanism forming the particular subject matter of the present invention, in the illustrated embodiment of the invention the knife operating mechanism of the Hadathat is, the machine is provided with a horizontal rotary knife shaft 5 suitably journaled in the carriage Gand driven by the engagement of a lug 7 on the rear end of theshaft, in a slot 8 formed in a drum 9 carried b, a stud shaft 10 mounted to rotate in a bearing on a standard 11 supported on the main frame, and driven by a belt-pulley 12. The carriage 6, with its adjustments, is the same in construction as the corresponding part in the Hadaway patent except that the arm 13 is not provided with a spring, a spring being unnecessary in the present construction, and the stop screw s14 engaging the arm 13 are used for adifferent purpose than heretofore, as will be hereinafter explained.

At the forward end of the shaft 5 there is mounted a disk knife 15. Ahorizontally arranged plate 16 is secured by set screws to insole S and the reinforcingplate 16 is the under side of the forward bearing for the shaft 5 and projects forwardly to a position below the knife. During the operation of the machine the forwardend of the plate 16 enters between the feather of the shown in Fig. 2, and its end portion cooperates with the knife to secure a clean severance of the fabric and also holds the fabric in a position which enables a severance without danger of the knife cutting into the feather. To this end a spring 17 Y coiled aboutthe shaft 15 bearing at its forward end against the frame 6 and at its rear end against a collar 18 fast in the shaft, being similar to the corresponding spring in the Letters Patent to John B. Hadaway hereinbefore referred to, operates to draw the knife toward the rear and hold its cutting edge yieldingly against the end of the plate.

Preferably, although not necessarily, the provided at its acting end with a'transverse slot 19 in which the knife may rotate. The plate 16 is adjustably mounted in the frame 6 to permit the proper setting up adjustment between it and the knife to be made.

The mode of operation of the machine to attain the object of the invention will be apparent to those skilled in the art. An initial adjustment of the screws 14:, for the size or style of sole being operated on, places the knife the proper distance from the operative end of the anvil or former 4 so as to effect a line of. severance spaced from the edge of the insole. The width of the feather in welt insoles varies, the widest portionbeing at the shank and it is at the shank only where a trimming of the fabric within the edge of the insole is most essential. It will,therefore, be apparent that the present method of trimming from the lip or rib of the insole as a gage, will prevent the fabric from being entirely removed from the feather along its narrower portions while yet producing a severance inside the edge at the shank, as

shown at the left of the insole S in Fig. 9.. Having set the knife to its desired position the reinforcing operation is proceeded with in the usual way. The various forming tools, as in the machine of the Hadaway patent, apply the fabric which is simultaneously trimmed by the knife. As is customary in machines of this type the upper surface of the plate 16 will be oiled to prevent the sticky fabric from adhering thereto as the insole is fed through the machine.

The present invention provides a simple and effective mode of gaining the desired object by means readily applicable to the pres} ent commercial machine for forming a bead or crimp in the reinforcing fabric and securing it in place, in the process of making what is known as the Gem insole.
