Specification of Letters Patent.

Patented Mar. 25, 1919.

Application filed June 29, 1917. Serial No. 177,628.

To all whom it may concern:

Be it known that I, CLARENCE TV. MorrA'rr, a citizen of the United States, residing at Maywcod, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Insole-Making Machines, of which the following is a specification. I

My invention relates to machines for making insoles for shoes. The machine is designed to produce insoles having marginal ribs or wales as shown, for example, in the Seaver Patent No. 607,396, and the Emmonds Patent No. 1,065,035. This present application involves improvements upon the machine shown in my prior Patent No. 1,198,470, granted to me September 19, 1916. In the machine of my said patent the dies and other rib forming parts were fixed in outline, thus necessitating the making of a number of new parts every time an insole of different size or shape was wanted. The general object of the present invention is to make these parts adjustable or conformable so that by using suitable easily made templets the principal parts may be used over and over again for insoles of different sizes and shapes. The invention includes a number of contributory concepts which cannot be readily described in a few words, but which will be completely understood from the following description and claims. The mechanisms which embody the improvements and enable me to carry out the objects of the invention are illustrated in the accompanying drawings in which:

Figure 1 is an assembly view chiefly in vertical section of the upper and lower die carriers and associated parts.

Fig. 2 is a top plan of the parts shown in the lower portion of Fig. 1. These include the recessed die, templets, and templet holder.

Fig. 3 is a distributive view in perspective of the chief component parts of the projecting die shown in the upper portion of Fig. 1.

Fig. 4c is a sectional view looking upward on the line 4-4, Fig. 1.

Fig. 5 is a sectional view on the irregular line 5-5, Fig. 1.

Fig. 6 is a bottom perspective view of the projecting die and associated parts. This is an assembly view of the parts shown sepa rated in Fig. 3.

Fig. 7 is a perspective view of one of the clamps which helps hold the wale while the body of the insole is being pasted or otherwise secured to the fabric.

Fig. 8 is a distributive view in perspective of the projecting and recessed dies and associated parts. These parts are shown assembled in Fig. 1.

Fig. 9 is a perspective view of a typical insole produced by the machine.

Similar numerals refer to similar parts throughout the several views.

It will be understood that the parts shown in the accompanying drawings may be substituted for corresponding but non-adjustable parts shown in my said prior patent,but it is unnecessary in the present case to illustrate the entire machine because the operation will be readily understood from the parts here shown and the design of the remainder of the machine may be varied without departing from the spirit of the present invention.

To facilitate an understanding of. the mechanism without reference to my prior patent, it may be stated that in producing one of these insoles, canvas or other fabric is first spread over the top of the recessed die, (see the lower portion of Fig. 1). The projecting die then descends and forces the fabric into the recessed die. This forms a downwardly projecting rib or wale which follows the outline of the to-be-produced insole at a slight distance from the margin thereof (except at the heel portion, where no such rib or wale is required). Next, a presser foot or plate descends from above and holds the fabric down while the projecting die is being retracted upward. After the projecting die has been withdrawn, a plate rises from beneath the recessed die and actuates a set of clamping fingers which thereupon grip the wale and hold the fabric in place. The presser foot is then lifted, whereupon the body of the insole, which usually consists of leather, is pasted onto the fabric. After this the trimming operation is performed, that is, the insole is cut to proper outline.

In the machine shown in my prior patent,

the recessed die is shifted laterally from under the projecting die before the body is cemented to the fabric, but my present invention is not especially concerned with the cementing and trimming operations.

Now referring to the mechanism illustrated in the drawin s, a platform 1 is supported in anv suitable manner. preferably being shiftable as in the machine of my prior patent, although the shiftability or non-shiftability is immaterial so far as my present invention is concerned. This platform is vertically apertured to form a guide for the vertically movable'push rod 2 shown near the bottom of Figs. 1 and 5. The

push ro'd has a socket 3 formed at its upper end, the socket being of increased diameter and seating upon the platform 1 Itforms .a guide. for the stem 4 which projects from the bottom of ,the finger-actuator 5 which ishere shown in the form of a plate some-Y times seating upon the spring 6 which rests upon the top of the socket 8. The fingeractuator is approximately of the size and shape of a typical wale and normally seat-s upon a platform 8 which is fastened to andsupported (by any suitable means, not shown) on the platform 1. A part 10 which, for convenience, will be termed the .box or lower templet holder rests upon the-platform 8 and has an; aperture in its bottom for accommodating the finger-actuator5. This holder 10 has upstanding sides 11 which retain two plates 12 and 13 which form the lower-templet. Diflerent designs may be followed, butlprefer to make the.

lower templet of two similar plates as it facilitates manufacture and also assembly when in use. The inner edges of these two plates form a backing for the clamps which retain the wale. The clamps, which are illustrated separately in Fig. 7 and are clearly shown in position in Fig. 5. consist of backs15 to theinner side of which are pivoted fingers 1'6. 'Said fingers'cooperate with their'backs to grip the wale as shown in Fig. 5. The backs are rigidly held in position by the studs 18 which pass between the plate 12 and 13' and out through sui-table apertures in thesides 11 of the holder.

'While the plates 12 and 13 may be held' spaced apart in any suitable manner, it is desirableto obtain the proper spacing by spacing-blocks 14, as. suggested in the lower portion of Fig. 1.

The gripping fingers 16 are provided with and actuated by adjusting screws 20 which. as shown IIIFIgS. 1 and 5, are engaged by the finger-actuator when the latter rlses.

This riseof the finger-actuator causes the fingers to grip the wale, as shown in Fig. 5.

The finger actuator is yieldingly supported upon the cushioning spring 6 at this time, and hence the danger of breakage is avoided. Atable .24 serves to support the fabric while the wale is being formed and subsequently thereto, the fabric being indicated inposition in Figs. 1 and 5 and being designated'bythe numeral 25.. The table is supported atthe heel end by a block 26 which has an aperture 27 for-receiving the stud .28 by-which the table may be secured to the templet holder. The said table follows the'general outline of the wale but is small 1 illustrated.

enough to'clear the clampingfingers 16 at all times;

The trimming is accomplished by means of a knife or cutter SO whlch passes around the outside of the'backs 15 of the wale clamps. It is mounted upon'a knife frame 31 which, at the proper time is .IlIO'VGd-UP- wardly to make the cut by the levers 33 fulcrumed upon thelugs 34 formed at suitable intervals upon the top of the templet holder 10. In the present. case there are six of these levers, as shown in Figs. 2 and 8,

although the number may, of course, be varied. The levers may be actuated. any

suitable, mechanism. Such mechanism .is

illustrated in my prior patent, but as it is 7 not directly concerned with the present in"- vention, it need not be here described or I have now described the recesseddie'and its associated parts. 'I will next describ the projecting'die and its associated parts.

The pro ecting die proper is indicated by the reference numeral 38 and,. as shown in perspective in Fig. (3, consists of as-trip of sheet metal. It is c'omparativelyfie'xible so f that itmay bemade to conform ,to the outline of the plates 40 and 41 which constitute the upper templet. The die strip 38 is held tightly against the sides ofsaidplates by studs or screws 42, the number and arrangement whereof are shown in Fig.4 and elsewhere. The number-of these screws maybe .varied and theirlocation changed. but fou'r are sufiicient for ordinary cases. The screws of the forward pair tap into the block 44,; while the screws'of 'the rear pair. tap into the block45. Block 44 is rigidly. fastened to or integral with the bottom of the upper -0 die carrier 47 ,as shown in Figs. 1,3 and elsewhere. Block 45 is movable, beingheld by the tightening. screw" 48, whichipasses freely through the block 49 rigidly-fastened to the bottom of the die-carrier, as shown,

' for example, in Figs. 3 and 4. Said screw I taps into the-block45 and by turning'the screw in a direction to tightenlt, the screws 42 are drawn toward theheel and, as said screws are locatedbehind the widest part of V the foot, tend to hold the die strip in tight contact with the edges of the plates 40, 41. Said plates have apertures 51 for accommos dating block 44 and apertures 52for accommodating block 49. The block 45 actsas a spacer betweenthe twoplates 40, 41, while the blocks 44 and 49 being rigid. serve to vertically position the plates 40 and 41. The die carrier 47 is reciprocated vertically at the proper time by a rod 55 at the lower end 'of-which the die carrier is fastened.

The presser foot holds the fabric down on 5 the table 24while the projecting die is being drawn upward out of the wale. In the present form,'it consists of aplate 58 fastened by screws 59 to theplate 60 which is I moved vertically at the proper time by the rod rods 61. In'the present case these rods are four in number and, with the plate 60, make a frame to which the interchangeable plate 58 is detachably attached. Plate 58 will be changed for each change in shape or size of the wale, whereas, the remainder of the frame, to-wit: the parts 60 and 61 and the operating parts therefor, (not shown), will remain as a permanent part of the machine. Upstanding fingers 64 rise from the plate 60 and form a guide for the die carrier 17, as best shown in Figs. 1 and 5. The die carrier 17 is preferably detachably attached to In the present design, said die carrier has a stem 66 rising from it, saidfstem fitting in a socket 67 formed at the lower end of rod 55 and held in position by a set screw 68, as shown in Fig. 1.

The operation will now be readily understood. Let it be assumed that the machine is empty and that the finger actuator 5 is down in normal position on platform 8 and that the upper die carrier is raised as in Fig. 1. The operator now spreads a layer of fabric upon the table 24:, then causes the upper die and presser foot to descend. As the upper projecting die is operated independently of the presser foot, it is possible for the two parts to move independently, and this, in fact, occurs according to the preferred program of operation. The projecting die enters into the space between the backs 15 and fingers 16 of the wale clamps, after which the presser foot 58, 60 reaches the fabric and holds it. The projecting die then moves upward and clears the fabric, whereupon the push rod 2 rises and, acting through the medium of the cushion spring 6, causes the finger actuator 5 to engage the adjusting screws 20 and force the fingers to move toward the wale and hold it against the backs 15.

My invention is not particularly concerned with the ensuing steps of the process and itis sufiicient for the present purpose to say that when the process has progressed as far as the stage mentioned, the lower die and its supporting parts will be shifted laterally from beneath the upper die and die carrier, as explained in my prior patent. The cementing of the body of the insole and the final trimming by the rise of the knife 30 will then take place to produce the finished article.

lVhen it is desired to produce insoles of different sizes or shapes, other plates will be substituted for the plates 12 and '13 in the holder 10. Likewise, other plates will be substituted for the plates 40- and 41 which determine the configuration of the projecting die 38. The plate 58 of the presserfoot will also be removed and a new one of suitable confignration substituted, It will be evident that when a new size or shape of wale is to be formed, it will be necessary to change only a few parts and these of comparatively simple construction. Practically speaking, the only parts which need to oe changed are the templets 12, 13, 10, 41 and the knife 30. The plates can be made with comparative ease and the two plates of each pair are duplicates of each other. It is not necessary to make fresh plates for right and left shoes, for all that is necessary is to turn the plates up side down and a templet for producing a right insole will immediately be available for producing a left insole. In other words, rights and lefts may be pro duced by merely reversing the templets,- that is, turning them over. This results in a great saving over the non-adjustable or non-conformable dies shown in, my prior patent. In the first place, it is not now necessary to make the parts both rights and lefts, because a single set of templets may be made to produce both rights and lefts. Furthermore, the parts which need to be changed are extremely simple compared with the parts designed to perform the corresponding function in my said patent.
