UNITED STATES PATENT onv GEORGE E. WARREN, F SWAMPSCOTT, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY CORPORATION, OF PATERSQN, NEW JERSEY, A CORPORATION OFNEW JERSEY.

v APPARATUS FOR .USE IN HANDLING WEL'IING.

Original application med June 27,1919, Serial No. 307,129. Divided and this application filed J'annary s, 1921 Serial No. 435,911. 1 Y K The present invention relates to apparatus foruse in handling welting and more particularly to an apparatus which is adapted 'to be employed in connection with a welt shoe sewing or other machine for operating on welting to protect the welting while it is n being supplied to the machine.

lVelting is usually supplied to the'shoe manufacturer in a length'of about twenty yards which is laid in acoil or hank and is tiedup in this form for storage or transportation. It is customary to transport these hanks in an uncovered condition in which the weltingis subject to soiling and in jury. When the welting is to be used, a days supply consisting of several'hanks is issued to the Welt sewing machine operator. Before use, the hanks are. immersed in water and when they have soaked sufficiently, the surplus. water is drained off and the hanks are then placed on the bench or on the floor behind the machine and the leading end 'of one of the hanks is inserted in the welt guide of the machine. Each of these hanks contains suflicient welting for sewing about twenty pairs of shoes of medium size. When the hank from which the welt is being drawn is nearly exhausted so that there is not enough welting to sew. another shoe, it is necessary either to splice the endof another hank'tofthe part of the hank left in the machine or to remove the short length of the first hank from, the machine and insertthe leading end of another hank in the welt guidei I -Obviously when this method is followed,

the welting applied tosuccessive shoes will vary 'eatly in condition. The welting which is first used will usually be excessive- .ly wet, after which its condition may improve as the water dries from the surface and permeates more evenly the body of the welting, and later it will-dry out and become relatively stiff. The condition of the welting is a very materialfactor in the production obtained from the welt sewing maannoys the operator and he is apt to" work condition of certain parts of the Welting may interfere with or prevent the proper formation of the seam or the proper at- 'welti'ng is not spliced, the short lengths "of weltlng containing less thanenough for a single shoe left at the end of each hank are usually wasted, thereby adding considerably to the expense of manufacture.

The object of the present invention is to provide an apparatusfor handling welting which is adapted to maintain the welting in a uniform moistened condition, particularly while it is being supplied to a welt shoe sewing or other machine.

With this object in view, the invention contemplates the provision of a receptacle forlthe receptionof a bagor package of welting with the upper portion of the bag turned back over the rim of the receptacle, and a tapered coverforthe receptaclehavin'gan opening in its upper'end for the passage of the welting from the receptacle,

to cooperate with the lower portion of the.

cover extending. within the receptacle to hold the margin of the bag in position with relation to the receptacle. The package of welting abovereferred to maybe employed in carrying out the method described and claimed inUnited States Letters Patent No. 1,552,588, granted Sept. 8, 1925, upon an application of which the presentapplication is a division.

The opening in the cover of the receptacle permits the weltingto be withdrawn from 'the'receptacle and fed me weltshoe sewing machine by the welt feeding devices of the machine. The covered receptacle restricts the circulation of air about the package of 'welting and p'rotectsit from the heat of the sewing machine, so that. the mass 'of welting is thereby maintained' in at-uniformly moistened condition. The tapering cover of the receptacle extendsjupwardly considerable distance to protect the welting during its passage to the sewing machine.

The several features of the present inventionwillbe clearly understood from the following description and accompanying draw ings, in which I from the machin-e, and a bag holder appliedthereto whiclrinay be usedin connection hwithfthe improved apparatus; Flg. 2 1sade- Figure lis a side elevation of a portion of a welt grooving andv beveli'ng machlne .Wltll a bag for receiving the welting-as it issues tail vertical sectionalview otthe holder illustrated. 111 Fig; 1; Fig.3 is a side elevation of a package'ot welting which'may be used in the improved apparatus; and Fig.

.The improved apparatus may be ein- I ployed. in carrying out the method described and claimedin the above mentioned Letters Patent. In carrying out this method, mechi anism ,is employ-ed for arranging a's trand [of welting in amass withina fabric bag to forma package o fwelting such as the one forming the sub3ect matter otan appl cation filed of even datev herewith. This mechanism, as illustrated, is embodied in a 'welt grooving and b eveling machine of the type illustrated and described in the patent to Merrill, No. 1 309,583, datedJulyS, 1919. Thewelt grooving and beveling machine is provided with a rotating welt guide 10 Imounted on a vertical axis within a hollow pedestall2 forming apart o f-theframe of the machine. The pedestal 12 is mountedon a stand .14 provided with upright supports or legs;1 6. Between the legs of the, Standis secured a bagvholder l8 consistinggofa sheet metal cylinder adapted to be inserted in the mouth of the bag. The bag; for the reception of the welting, which is indicated at 2O, is placed between the legs of the stand 14, and the upper, end of the bag is drawn over the end of the bag holder sothatthe bag holder will hold the mouth of the bag distended. In order, to hold the ,bag in position on the bag hold'eiya series otspring.

clips 22ers secured to the bag holder beneath. Which the upper margin of the bag may be inserted. lVith this construction, as the weltmg is delivered progressively tothe welt guide, from the welt; grooving and bevelingmachine, the welt guide. Wlll deposit the welting within the bag in-a mass without definlteor regular arrangement of coils, but

' giving twist to the weltin'g during each revolutionof the guide so that the welting will run freely. from the mass without tang-hngor twisjting when it is withdrawn progressively,th refrom.l

In thefurthercarrying out of the method of said Letters Patent, the coil or mass of welting within the bag is wet several hours before the welting is to be used, preferably by immersing the bag with the welting therein in Water; Then after draining cit the surplus water, theb'agflo'f welting. is set aside and the weltingallow'ed to mull within the bag, tlfeba'g restricting the circulation 0 i th u the 'w l nsaed re ee s. it from surface drying. At the end of few hours, the water will have uniformly pene-; vtratedthebodyot the welti-ng, produc ng a thoroughly mulled and cheesy] condition. When in this condition, the welting can ;be readily pierced by the sewing needle' without tearing the fibres of the leather and can the same to the shoe. I V

FNhen the welting is to be fsed, the bag withthe welting therein ispla c'ed in the improved apparatus, forming the subject matter ofthe present application, which is located a position convenient to the sewing machine and the bag is opened and the leading end of the welting is insertediii the welt guide of the sewing machine Theiniproved; apparatus is so constructed as to Irestrict the circulationof air about the, bag

The readily shaped as required in attaching v and thereby prevent rapid drying of the a bag and the welting therein. The apparatus comprises a cylindrical can 24 torthe reception ofthe bag of welting, havinga tapered cover 26 formed at its upperiend with a relatively small opening 28 for the passage of the welting' r0. thefsewing'inachine. The diameter and height of the.,ca11

24 is preferably such that the bag will :till the can with the sides of thebag supported. by contact with the interior of-the can from the, top tothe bottom ofthe bag. The upper or marginal .portion, at the noutlro'l':

the bag may be turned back. over the rim of the can, as shown in Fig. i.' Preferably, as indicated in Fig. 4E thebottom of thecan is oplen asl well as the top-and the bag is adapted to rest upon the floor or: other sup- The tapered cover ,26' extends up-- wardly a considerable distance to protect the I portion of the welting extending to the sewing machine As shown the can may be open at the bottom as well as atthe' top "toenable the canto be placed over the bag and thus avoidthe necessity of lifting the bag in the can. It will be apparent that the i1n= proved apparatus will thus prot'ectthe welting from the drying conditions about the sewing machine due to the heat of the machine and will maintain the welting in the proper moistened condition.

While it is preferred to employ the specific construction and arrangement of parts illustrated and described, it will be understood that this construction and arrangement is not essential except so far as specified in the claims, and may be changed or modified Without departing from the broader fea tures of the invention.
