WELT TEMPERING MACHINE Application filed September 21, 1927. Serial No. 221,056.

This invention relates to machines and processes for preparing welting for the inseaming operation and more particularlyto a novel machine and process especially adapted for handling and properly tempering welting just prior to its being drawn through the Welt guide of the inseam sewing mach ne, but it will be understood from the following description that the machine may be used in combination with, or auxiliary to, other kinds of machines for operating on welting, or it may be used wholly independently of any other machine; For the purpose of defining the novel features and advantages of the present invention, Goodyear welting will be referred to generally hereinafter, but thosev skilled in the art will recognize that the invention is not limited to tempering only this type of weltlng.

VVelting of all kinds may come to the shoe manufacturer from the welting manufacturer in one of two forms according to the manufacturers needs. The majority of shoe manufacturers desire that the welting be delivered 2 to them in hanks while the remainder desire that it be wound on a spool. The present invention will handle equally well both hanked or reeled welting and will temper either perfectly withoutchange in the devices which direct the welting through the water.

Prior to the present invention many attempts have been made to design a machine for wetting or moistening welting in a manner to insure that only the portion of the welting thatis to receive the inseam stitches will be so tempered as to insure a tight inseam when presented to the stitch-forming mechanism of the inseam sewing machine. These have included a machine having provision for delivering water through" a nozzle into the stitch-anchoring groove in the flesh Side of the welting; another having provision for quickly. drawing the weltingon edge be-j tween side guides, rising above the water level,

in a tank of water with its beveled edge immersed to at least the vdepth of the groove; and a third having provisionfor wetting onlythe flesh, side of'the welting. The aim and purpose of these various attempts at perfec-v tion inwelt tempering has beento prevent the welting from being wet too much or too long by the water and particularly to prevent Wetting the grain surface of the welting that is to be exposed on theshoe. Success has not crowned these inventions as none are in commercial use today and shoe manufacturers have, up to the introduction to then of the machine of this invention, been forced to continue to use the crudest and earliest known method of tempering welting, namely,- dipping the entire blank in water and then waiting for it to dry out enough to insure sewing a tight inseam. v V When the process of dipping the hank to temper the welting first came into use the leather used for welting was prepared in quite a different manner than it is today. The tanning processes were such that the hard leather needed, before sewing, to be soaked and then to dry and mull under cover until it became soft and. cheesy thus insuring a tight inseam but, at the same time, developing many disadvantages. Today the leather for welting is curried before it is stripped into fillets and is, therefore, quite mellow after the cutting operation to produce the grooved and beveled strand. Such welting does not need to be soaked and then mulled. Its tann'age is such that the only necessary treatment is a moistening of the inner margin that is to receive the inseam stitches. And yet, because no satisfactory process for merely moistening has heretofore been developed, the welting of to-' day is treated prior to sewing just as it was when soaking was essentiaL:

' Many disadvantages flow from submersion of the hank in water. If soaked too long the welting, particularly narrow and thin wommuch it becomes brittle and weak in the fibre, particularly on the grain side, which interferes with the inseaming and welt beating operations and promotes cripples. Unless a hank, tempered. by submersion, V is entirely used at the end of a days stint then the unused remainder may become so hard and brittle by the next day that it requires: re-temering with the attendant disadvantages. Veltin-g today is made from high grade leather which is so tanned that it is meant to be wet only once and then harden, where water has been applied, while on the shoe. A second all over wetting will cause it to shrink in width and become harder. Aside from a loss of shape, which is particularly disadvantageous because manufacturers watch the Width of welting (extension on the shoe) down to of an inch and further, the hard welt is more difficult to sew and operate on later. Velting leather is always stretched before cutting into fillets and it is the later shrinking after tempering which hardens it and tightens the inseam.

From the foregoing it is obvious that welt tempering is a delicate and highly important operation the main requirement of which has always been, but not attained up to the time of this invention, to wet or temper only just enough of the inner margin of the welting to enable the inseam sewing machine to sew a tight seam, and at the same time be sure that no water seeps over, or in any way is drawn toward or impinges upon, the grain surface that is to be exposed on the shoe. Thus all the disadvantages hereinbefore recited are wholly eliminated. A further advantage of correct welt tempering comes from the ability to immediately sew .and beatout the sewed Welt, whereas with welting tempered :by submersion there must be a drying period of several hours between successive operations.

The object of the present invention is to provide a process of tempering welting, and

a machine for carrying out the process, that will invariably wet or moisten only that much of the grooved margin of the welting as is required for sewing a tight inseam, and no more. The various novel features of the machine through which this is made certain will be ascertained from the following clescription.

To the accomplishment of this object and such others as may herein-after appear, as will readily be understood by those skilled in the art, the invention comprises the features and combinations of parts hereinafter described and then particularly pointed out in the app ended claims.

The features and scope of the invention will best be understood from a description of the preferred embodiments thereof illustraed in the accompanying drawings, in which:

In this figure the circular dotted line represents the column of an inseam sewing machine such, for example, as is disclosed in Letters Patent of the United States to Andrew Eppler No. 1,076,878, dated October 28, 1913;

Fig. 6 is a view, in rear elevation, of the means at the forward end of the tank for directing the strand to the welt carrier;

Fig. 7 is a view, in front elevation, of a modified form of weltcarrier;

Fig. 8 is a view, in front elevation, of the carrier shown in Fig. 7, detached from its support;

Fig. 9 is a view, in right side elevation, of the entire machine fitted with the modified form of welt carrier; and

Fig. 10 is a view, in longitudinal section, of the tank with welting being directed therethrough by the modified welt carrier.

In the embodiment of the invention illustrated by F 1, 2, 3 and 5 of the drawings I show what I term a universal welt carrier indicated generally by 10, so constructed as to be adjustable to receive many different sizes of welting within certain limits. The guide 10 is suspended above a water tank 12 from a cross-bracket 14 which is adjustable vertically on guide pins 13 and 15 secured at each side of the tank 12.

The water in the tank 12 is maintained at a constant level by means of an intermittent feed, from the supply contained in a bottle or-other container 16 (see Fig. 9), induced by evaporation from the tank under the wellknown barometric principle. The contents of the bottle is sealed to the atmosphere, by reason of its air-tight support in the bottle holding mouth 17 (Figs. 5 and 9), and evacuation to the tank 12 can occur only when the water level in the tank is lowered sufliciently to uncover the upper end of a water gate 18. This water gate has an inverted V shape (as indicated by dotted lines Fig. 5) so that the replenishing is in such small quantities as not to disturb the calm of the water in the tank 12.

The adjustable guide bracket 13 provides for setting the welt guide 10 to a predetermined depth in the water of the tank, to accommodate any size or style of welting held by the carrier, i. e. in order to obtain the same (Fig. 5). .Dependingfromtthe collar:24'

is a tubular extension 23 preferably integral with thecollar and ,in-any event adjustable vertically on the pin 13 with the collar. This tube 23 forms a slide bearing, for thebracket sleeve20. A crank arm 26, having a handle 28, is pivotally mounted on the collar-"and-a;

1 vertical, pivoted link connects the sleeve 20 tothe crank arm. The crank arm' and link form a toggle with itsknuckle; at '29 and-a stop pin 31 on the collar serves to maintain the togglestraight when thehandle28 is moved to the left, as shown byFig. 1. When the toggle is straight, or extended, the welt carriersupport 14 isat its lowest position determined by the setting of the collar 24. By loosening the set screw 25 the support 14and its depending welt carrier 10 may be moved together, due to the toggle connection, toward or from the water'leveluntil thedesiredsettingis attained.- It may be desirable, at times, 7

to wholly remove the carrier and support from the pins 13 and 15. In order to preserve the setting attained by theprevious adjustment, and eliminate re-adjustment when the parts are replaced, thelower end of the pin 13 may be threaded and provided with a nut32 (Fig. 1) to be screwed against the lower-end of. the tube 23 afteran adjustment has been perfected and then held in POSiillQll;

by, a lock-nut 33 or other suitable securing means. The nut'32 thus functions as afixed,

stop to determine the verticalposition of the welt carrier with respect to the water level.

The universal welt carrier;,10 has three parts; a body member 34 hayingextending pins 36 and 38 set at right angles to each other,

a side-guide member 40 slidable on the pin 36, and an end-guide member 42 slidable on the pin 38. The adjustable members 40 and 42 are held at any desired position on their pins by set screws 41 and 43 respectively. The side-guide member 40 is constrained to move longitudinally,; without rotation,; on its pin 36 by a face bearing 44 between it and the body member. The end-guide member 42 is constrained to move on its pin 38 in a likemanner by a .slide bearing comprised of a.

fork 45 whichembraces the reduced end of a lateral leg 46 of the side-guide member. The, forked bearing serves to maintain the end and side members in the same plane under all conditions of adjustment and the face bearing co-operates therewith; to maintain the end-:and side memberscin the plane of. the

body member, It is obvious from a studyof Figs; 1 and 2 how the size of.the :0pening; or.

guideeye-formedby the'three membersof the.

welt carrier maybe altered to. accurately'engageand directthrough the water tank differentgwidthsiror thicknesses of welting.

It is of the utmost importance that the weltinggdrawnthro'ugh the welt carrier, and thusithrough the water,,'be so held that only its grooved:-margin will be moistened. In-' suranceimustbe had that the portion of the grainwhichis to be BXPOSGClOIl the shoe is protectedrfrom immersion; To this end pro-T visionis; made: for setting the welt carrier in such QIPOSltlOIl that the welting, while in the guide 'eye, stands oblique to the water level with I its .grain side uppermost and its grooved ;margin tipped downward for immersicnras'theweltingis drawn across the tank 12:. ,g This angular adjustment of the welt carrier issecured by making a head 48 onthe. body memb,er;34,slidablein a cu'rvedway 50. (see.,Fig.-'t3) fOI'lYlGCllOl'l the carrier support 14. The carrier l'Qjs held :in any desired position along its support 14 by. a lock screw 49....

.lwill now describe afeature of my welt carrier that I :deem to be essential in that it functions to maintain the grain surface to be exposed on the-shoeperfectly dry through out the tempering operation. .It will be 010-.

served :(Fi s. 1 and 2) that the lowerend of thebod'y member 34 of the carrier is cut away at 52, preferably but not -necessarily,.a semi-' circular, cavity,;.the;lower corner 54 of-which bears on thek welting either directly at, or if desired just beyond, the grain corner formed by cutting. the'welt: bevel, or oppositethe groove in the flesh side. The are of the curved way, 50 is struck from this corner54 asav center and all angular movement of, the welting. relative 'to .the water level takes place about this fixedtcentenof adjustment. The

preliminary vertical adjustment of the welt carrierIO isisuch that the corner 54 stands at,; or possiblyjust above, the waterlevel, hence nomatter. howmuch theangle is decreased between the flesh sideof the welting.

'andwater level, in order towet more of the flesh side, the grain side of the welting will never be immersed beyond the line of pressure of the corner 54.: Furthermore the cavity; 52- provides a shoulder rising from the grain functioning to prevent water being drawn by, capillary attraction beneath the I grain side wall of the guide-eye and thence on to that, portion of the grain to be exposed on the shoe. Moisturewill not seep upward beyond the corner 54 but'it will do so if the grain side wall of the guide eye is made as a contmuous surface similar to the flesh side wall formed by the leg 46. The flesh side lee ward and from the fixed point 54 on that member thus preserving the grain side depth of immersion for all sizes of welting for which the carriermay be adjusted.

The machine is set at a convenient height upon a bench or table and the welting to be tempered comes from a hank .or reel at a lower level, passing upward over a directing bar 56 (Fig. 6) having an upper protecting pin 58, on the forward edge of the tank 12. The surface of the bar 56 slants relatively to the water level, the obliquity approximating that. of the guide eye of the welt carrier to relieve strain on the guide eye. As best shown by Fig. 2 the ends of the guide eye may be provided with rounded abutments 59 to further assist the welting in an easy passage through the welt carrier. After immersion the welting passes beneath a guide roll 60 which is freely rotatable on a pin 61 held at each end in brackets 62 (Fig. 5) that are angularly adjustable in ears on the tank walls to enable the guide roll to be set in the best position for lifting the welting out of the water immediately it has passed beyond the welt carrier. From the roll 60 the moistened welting passes upward (see Fig. 3) conveniently to the measuring roller 64 of the inseam sewing machine. This roller is provided with clamping mechanism for holding the welting after the welt cutting operation is performed on completing the sewing of a shoe.

The general location of the roller .64 is indicated by dotted lines in Fig. 5 and this figure shows also how the machine of the pres ent invention may be mounted on a rear corner of the sewing machine work table. The work table 65 has a bounding lip or rib 66 from which is hung a base plate 68 for supporting the tempering machine. The base plate has two holes 69 at one end which, when the plate is situated diagonally beneath the table 65 (see Fig. 5), are just outside the rib 66 and this end of the base plate may thus be clamped to the table by U-bolts 70 which pass upward and hook over the rib. The other end of the base plate is provided with two spaced posts 72 (see also Fig. '9) having reduced ends forming shoulders on which rest collars 73 at the ends of arms 74 extending laterally from the tank 12. The machine is removable at will from the posts 72 for dismantling, inspection or repair.

From the measuring roller 6% the welting goes to the welt guide of the sewing machine and from thence to the work-feeding and stitch-forming mechanisms. Between the two rolls 60 and 64 the welting is turned over so as to lie flesh side up as it passes to the sewing machine welt guide, in proper position to be stitched to the shoe. This twist in the welting does not interfere with .the advance of the tempered welting by the workfeeding mechanism because there is about a 1, see; 9 e0 pleting the operation on a shoe, the operation of the clamp on the roller 64 holds taut the length of welting between the measuring roller and the roll 60 and prevents the por-' tion between the roll 60 and the weltcarrier 10 (see Fig. 3) from dropping downward into the water. If there is any slack the weight of the substantially vertical run will cause it to sag downwardoutside the tank and thus straighten the portion inside the tank and hold it above the water level.

At night, after the days work is over, it is not necessary to unthread the welting still unused from the guide eye of the carrier 10. By moving the handle 28 (Fig. 1) to the right the toggle 2630 is broken and the support 14 with its welt carrier is lifted on the tube 23 to a position where the welting is above the water level. A contractile spring 75 connected to pins on the sleeve 20 and fixed collar 24: prevents the guide '10 from sliding down again due to its own weight. In consequence the unused welting, not being left overnight in a soaked condition as was the practice prior to this invention, is in prime condition for tempering and stitching when the sewing machine operator starts the next morning. 7

In the modified form of the invention shown in Figs. 7, 8 and 9 the tank 12 and its water supply and support, the forward bar 56 and the rear roll 60,'and in general the adjusting mechanism for setting the welt carrier as a whole for correct immersion of the grooved margin of the welting are all unchanged. In Fig. 7 the dot and dash lines show the raised position of the welt carrier after the handle 28 has been moved and the toggle 2630 broken as has hereinbefore been described.

The construction of the welt carrierconstitutes the principal modifications. The modified welt carrier comprises a disk having a plurality of guide eyes of different sizes for accommodating different sizes of welting. This disk 80 is mounted in a split? ring portion 82 depending from the welt carrier cross-bracket 84. The disk has a flanged forward edge (see Fig. 10) and form. Each cavity 86 in the grain side wall has the same abrupt grain side engaging corner'54, as hereinbefore described, to prevent wetting of the grain by capillary at traction between. the wall-and welting,- and any one of these several guide eyes, when in in operative position as shown by Fig. 7 serves the same endas doesthe adjustable guide-eye of "the preferred" form; Each guide-eye opens through the peripheraledge of the disk 80 thus permitting the disk to be applied to welting already threaded through the machine (see Fig. 8). There may be heavy places in the hank and while the fit should be close yet the welting should travel freely through the welt carrier. r

In Figs. 3 and 4: there is shown a device, applicable to either form of' the invention, for taking all kinks out ofthe welting before passing over the directing bar 56. Kinks are very apt to form in welting drawn-from a hank and this is one advantage of using reeled welting. A bracket '90 projects forwardly from the front wall ofthe tank and carries a loosely rotatable directing roll 92 set slightly oblique to the horizontal-inconformance with the obliquity of the directing bar 56.- Depending from the bracket 90 are two bars9 having inwardly turned ends (Fig. 4;) about which-is clamped. a mouth formed of two pieces 5360f generally triangular form, the pointed ends being directed downward toward the hank of welting.,- The mouth piecesconstitute a guide-for thewelt andihave smooth opposed facesispaced'apart a distance to accommodate the thickest 'welting that may be used. Thepointedends arerounded, forming together a'nose about which? a guard in the formof a ring 98 is soldered. If the welting becomes twisted (see- Fig. passage through the guide formed by the two pieces '96 will cause it to untwist: This untwisting'may develope a kink (see Fig. 4 in which event the edge of the "kinked welting rides against the under surface'of the v guard 98 and eventually is thrown back after the twisted portion has been fed through. A device of this nature is quite necessary in feeding to the machine from hanks. In setting up the machine it may be found that the bench,'or other support, is' not level in which event the water level will not be parallel to theupper plane of the tank as illustrated by Figs; 1 and '9,jshowin'g the ideal" condition. Under such conditions the welt carrier is first adjusted both'vertically and angularly, as hereinbefore described, to as perfect a position aspossibleandth'en the" water level is changethf'is found necessary to prevent wetting more than the grooved margin of the welting, by the water level adjustment shownyin Fig. 9f The month 1-7 for receiving the bottle neckf-is provided with avertically adjustable bottle neck-hold-' er 100 held in anyd'esiredpositionby set screws or other suitable'se'curingmeans; By

altering the vertical location ofy'thefmouth erly-supplement the welt carrier adjustment and insure a' passage of the stranda'cross the tank without wettlng its grain surface to be exposed on the-shoe.
