WILI'JIAM GORDON, 0F BOSTON MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY COMPANY, OF PATTERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

Specification of Letters Patent.

To all iohom it may concern:

Be it known that I, VViLLIAM Goanox, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Machines for Making Insoles; 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 usev the same.

The present invention relates to machines for making insoles, and more articularly to a featheneclging or edge-hove ing attachment. for insole channeling machines.

In the manufacture of insoles the stock is first cut up into blanks having the shape of the completed sole and these blanks. are then passed through a channeling machine which cuts a channel in one surface of the sole and simultaneously forms a lip or channel llap and which also either splits the edge of the blank to form another lip or removes a'portion ofi'he stock from the edge of thochain neled surf a e of the sole to form a shoulder at the baseof the channel flap or lip. Insoles made in this manner present a sharp cd e at the margin of tho unchanneled or .un l ipped surface of the sole, which edn'e tends to cut the lining); and upper of the completed shoe. Also when the shoe is worn the margin of the insole sometimes curves upwardly and this sharp edge forms a ridge upon the inside of the shoe which renders the shoe extremely uncomfortableto the foot of. the wearer. To remove this sharp edge the margin of the unlipped or unchanneled surface of the sole is sometimes beveled, the

'beveling being performed as an operation separate from the operation of channeling ,the sole. This separate operation, however, adds to the cost of manufacture and some quently is usually omitted.

The object of the present invention is to provide means whereby the edge of the unlipped on 'unclianneled vsurface of the sole can be beveled simultaneously with the formation of the channel and lip or lips, so that an insole having the edge of its unchanneled or unlipped surface'beveled can be produced without subjecting the sole to a separateoperation andwithout adding tothe cost of manufacture. With this object in view the present invention contemplates the provision in a an chine for making insoles provided with a li forming knife or knives, of a bevelino' knife arranged to act on the edge of the unlippcd surface of the sole. The lip forming knife or knives may he of any usual or suitable shape and arrangement, as the invention. broadly considered, contemplates the use of a beveling knife arranged to act on the edge of the unlipped surface of the solo. in combination with either a channeling knife which cuts a channel and forms a lip or channel flap, or in combination with an edge splitting knife or knife for forming a shoulder at the edge of the sole.

In insole channeling machines the edge gage is usually movably mounted so that. it can be moved during the operation of the machine to vary the position of the sole edge with relation to the lip forming knife or knives. It is desirable that the bevel formed at the edge of the unlipped surface of the solo be uniform throughout, and accordingly. in the preferred form of the pres I {embodiment of the invention hereinafter described, the movement of the beveling' knife with the edge gage con \cniently produced by mounting the knife upon the gage.

In addition to the features of invention above referred to, the present invention also consists in certain constructions and a rrangenient of parts hereinafter described in whicha Figure 1 is a view in side elevation of a portion of the insole channeling machine with the preferred form of the invention applied thereto, so much only of the machine being illustrated as is necessary to show the connection of the present invention therewith. Fi'g. 2 is a sectional plan view illustrating the relative arrangement ofthe work support, the feed wheel. and the ohanne-lin'g and beveling knives. Fig. 3 is an end view of the edge gage with the support for the unlipped surface of the sole and the bevcling knife mounted thereon. Fig. i is :1 i i:-

tail sectional view illustrating the appeal 'trated in Fig. 7, lookin With the exception of the edge gage and the parts mounted thereon. and a slight change in the work support hereinafter re ferred to, the parts of the machine illustrated in Figs. 1 and 2 are constructed and arranged in the same n'ianner as the corresponding parts of the well-known Goodyear insole channeling machine, 1 indicating the work support. the feed wheel. 3 the channeling knife. 4- the edge splitting knife. -5 the presscufoot for the channeling knife. and tithe presser foot for the edge splitting knife. I

The beveling knife is indicated at; T, and as illustrated nomprises a shank. portion curved in the arc of a pircle and provided at one end with a cutting edge 8. The upper surface of the knife grooved, as is clearly shown in Fig. 10, and the edge 8 formed by a bevel on the lower side of the knife so that the edge of the knife is curved and acts to produce a rounded edge on the nnlipped surface of the sole as indicated at 9 in Fig. 4. The heveling knife is mounted upon a. knife carrying block 10 which is provided with a curved-knife receiving guidewav It. the upper surface of the knife being recessed as indicated at 12 to receive a projecting flange, 13 of the guidcway. A cl'an'iping'plate 14 is secured to the block 10 lay screws 15 and frictionally engages the hevcling knife so as to securely hold it in any position to which it is adjusted. The knife carrying block 10 is mounted upon the edge gage of the inach ine will he hereinafter described.- the hcveling knife being m'l'fingl'd in a l'lOtlZOiltal plane with its cutting edge extending transversely to the direction of feed, The position of the knife in the machine will be clearly understood from an inspection of Figs. 1 and and it will he soon that by adjusting the knife on its guidcway in the hlock it). the cutting edge ol the knife will be adjusted in the direction of teed. The

cutting cdgeol tln knitccan ihns holn'onght,"

18 pro ided with a, horizontal lip ll) the edge gage and block 18 and screwing into the block 10. The cutting edge of the hex-cling knife can thus be adjusted in the plane of the sole transversely to the line of feed by adjusting the block 18 on the edge gage 21. and the cutting edge of the knife can be adjusted in a direction perpendicular to the plane of the sole by adjusting the block 10 upon the block 18. By means of these adjustments the cutting edgeof the knife can he brought into a position to act properly upon the edge of the unlipped surface'of the sole and remove any desired:

amount of stock therefrom.

The edge gage 21 .is mounted in the. same unlipped surface of the sole is uniform throughout. 7 v 1 In order that the bevelin'g knife may act with 'certainty to remove the skiving from the edge of the sole, it. is necessarythat means in addition to the Work support be provided for su iporting' the unlippcd surface or the sole in proximity to the knife.

In the illustrated embodiment of the inven tion accordingly, :1 support 23 has been provided which. as shown, consists of a plate formed integral witlr or secured to the edge gage. This plate projects from the edge gage beneath the sole and is received in an annular recessQd cut in the periphery of the main .work support. The plate 23 moves with the edge gage and thus serves at all.

times to support theunlipped surfaceof the solo/m proximity to the cutting edge of tho howling knife.

The operation of. the machi in the drawingswill be clearly understood from the description ahove givcn of the construction and arrangement of the various parts. and it need only be stated that as the insole is fed through the machine the channeling knife acts'to"forii1 the channel" 25 9:rrcd cinhodiincnt of-the invention having ne illustrated l been is 1.
