WELT-ATTACHING Macrame.

Specification of Letters Patent.

Application filed February 16, 1917. Serial No. 149,118.

To all whom it may concern:

Be it known that FRED E. BAILEY, late of Manchester, in the county of Hillsborough and State of New Hampshire, deceased, invented certain Improvements in Weltitttaching Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates particularly to welt attaching machines and is herein illustrated embodied in a machine especially designed for attaching a strip of welting to a shoe sole.

in the manufacture .of McKay sewed shoes it frequently dosiredto' attach a strip of welting to the marginal portion of the upper surface of the outersole' of the shoe. This welt, commonly termed a mock welt, does not perform the usual function of a welt but is applied chiefly or solely in order that the finished shoe may have the appearance of a welt shoe so'far as possible. The strip of welting has commonly been attached to the sole by means of metallic fastenings inserted near the inner edge of the welting where they will be covered when the soleis attached to the upper. It has been founddesirable to supplement the metallic: fastenings by the application of cement to the lower surface of the welt in order to effect a closer union of the weltand sole and thereby impart a more finished appearance to the shoe. Heretofore, the application of cement ha been a hand operation and consequently comparatively slow and expensive and lacking in uniformity and neatness.

The general object of the present invention is to provide an improved machine which, without sacrifice of other utility, shall be especially adapted for so performing the above mentioned welt attaching operation as to eliminate the necesslty of applying the cement in a" separate manual operation. V

In accordance with this object of the invention, the'illustrated machine is organized to nail the welting progressively to the sole and at the same time to apply cement progressively to one surface of the-weltmg-as the weltingis led step by step to the fastening inserting point, the metallic fastenings pressing the successive portions of the welt against the sole to cement the welt to the sole and thereby supplement the holding power of the fastenings. By thus simultaneously tacking and cementing the welt progressively to the sole, not only is the welting securely attached, but all parts of the welting are caused to adhere uniformly to the sole, eliminating cracks between the welting and the sole.

It is important to the satisfactory attachment of welting that the welting be soft and pliable. To this end, it is usual to nail the welting while it is in temper, that is, in a somewhat moist condition. It has been found that the welting can be rendered substantially more pliable and its handling and proper attachment thereby materially facilitated if heat is applied to the moistened welting just prior to the welt attaching. Furthermore, even though the cement reservoir is heated so that the welting is coated with the cement while the cement is in a heated condition, the cement coating on the Welting; is very liable to dry before the attachment of the welting to an extent to impair the holding power of the cement or prevent effecting proper adhesion between the surfaces to be united. Also, the welting' is liable to stick in the welt guiding parts as the cement coated welting is led to the nailing point. This tendency is aggravated if, as is usual in operations of the character above de scribed, quick drying cement is employed, and the difficulty is particularly pronounced whenever the operation of the machine is suspended even temporarily.

To obviate these difliculties, the illustrated machine is organized not only to apply heat to the cement in the cement receptacle or reservoir but alsoto apply heat to the cement coated welting near the nailing point, thus rendering the welting substantially more pliable and also insuring that the efficiency of the cement will not be impaired and that the coated welting will not stick even during the periods of inactivity of the machine.

In addition to the said features of the invention, the illustrated machine also in- Patented @ct. 29, 1918.

eludes the provision of novel means for accurately and quickly severing the attach ed welting from the source of supply.

Vhile the invention is herein described with particular reference to its utility in performing the particular operation above mentioned, it is recognized that various features of the invention may have other uses. It is also to be understood that the term nailing herein sometimes employed for convenience is not intended to be restrictive to any particular kind of metallic fastening. Other features of the invention will be brought out in the following specification with its appended claims. A preferred form of the machine organization is shown in the accompanying drawings in which;-

Figure 1 is a front elevation of the machine;

Fig. 2 is a top view of the welt holding racks and the cementing mechanism;

Figs. 3 and t are top and side views, respectively, of the welt severing device;

Fig. 5 is a section through the welt guide; and

Fig. 6 is an end view of the welt guide.

As shown, the fastening inserting mecha- The illustrated machine'includes a column 10 on which is supported a stand 12 carrying a work support 14. The driver 16 car ried in a driver bar 18 is operatively related to the work support and has associated with it a nail supplying mechanism, as indicated by the depending arm 20 supporting the strip carrier and by the cutter carrying lever 22.

Welting is supplied to the work support 1a of the machine from racks 24 mounted on a bracket 26 supported on a cement receptacle 4-2 and hence, indirectly, by the column 10. These racks comprise a series of parallel plates 28 of the desired contour which are held in spaced relation by means of bolts 30 and 32, the latter being extended at each end and slidably supported in bearings 34 and 36 upon the bracket 26. A han dle 38 may be provided upon one of these bolts in order that the racks may be readily adjusted. Preferably a snring-pressed plunger 40, shown in dotted lines in Fig. 1, is mounted. in the bearing 36 and this plunger cooperates with suitable notches in one of the bolts 32 in order to retain the racks in adjusted position. The bolts 30 are preferably provided with rollers over which the strip of welting is delivered.

A cementing device is located between the racks 24; and the work support and com prises a cement receptacle l2 attached to a bracket 43 on the column 10. To maintain the cement in the receptacle uniformly in proper condition, this receptacle is preferably provided with a steam chamber 44: to which steam may be supplied by means of a pipe l6 and from which it may be exhausted by means of a pipe e8. Journaled in operative relation to the cement receptacle 42 is a cement wheel 50 which is driven by means of a worm and gear, shown at 52, said worm being in turn driven from a pulley 54. upon the main shaft of the machine by means of a belt 56 running over an idler 58 and a receiving pulley 60. The pulley 60 is connected to the worm 52 by means of a friction. clutch normally spring-pressed into engagement but adapted to be manually released by the handle 64. On the cement receptacle and adapted to bear against the descending edge of the cement wheel 50 is a scraper 66. The strip of welting is guided into contact with the cement wheel 50 by means of a guiding roller 68 mounted on a stud 70 on the bracket 26.

Between the work support and the cementing device is a welt guide 72 which is intended to guide the welting to the nailing point for attachment to the sole. This welt guide is provided with a hollow chamber 73 to which steam is led from the supply pipe 46 and exhausted through a connection to the pipe 48. A stripper plate 74 is mounted at the entrance to the welt guide to remove any surplus cement which may have been applied to the strip of welting. By the provision of means for heating the welt guide, it is possible to apply heat locally to the strip of welting, to which cement has been applied, to render the welting more pliable and to soften the cement on the welting just prior to the application of the welt to the sole, and also to insure that the strip of welting will not stick in the guide, even during the periods when the machine is at rest.

pivoted to a bracket 84. supported on the frame of the machine and is normally held in upward position away from the work bv the action of a spring-pressed plunger 85. The downward movement of the knife is limited by the contact of a locked bolt 88 in the knife handle with a stop 90 so that the welt will be exactly severed without injuring the sole. Movements ofthe knife are guided by a roller 92 on the blade holder 7 8 entering a slot 94 formed in the bracket 841 The uppe'r'end of the blade holder is pivotedat' 96 to the handle 82.

In operation, rolls of welting of the desired character will be placed in the racks 24; and these racks adjusted by manipulation of the'handle 38 to bring the roll of welting of the desired character into alinement with the cement wheel 50. A strip of welting will then be led over the roller on one of the bolts 30 and under the guide roll 68 over the top of the cement wheel 50 to the welt guide 72. If the cement has been softened by previous heating, the cement wheel will be readily rotated by means of the belt 56 from the drive pulley 54 mounted on the main" shaft of the nailing machine. If, however, it is desired to operate the nailing machine while the cement is still cold, as when starting themachine in the morning, this may be readily accomplished by manipulation of the clutch handle 64 to release the worm drive 52. The sole or other work to which the welting is to be attached may be placed upon the work support 14 and the strip. of welting pulled through the welt guide 72 into the desired relation with the sole. Thenailing machine will then be operated in the customary manner to insert metallic fastenings to nail the strip of welting progressively to the sole and to effect the cementing of these parts by repeatedly pressing them together as the nails are in serted. After the last fastening has been inserted, depression of the knife 76 by a quick blow on the handle 82 will sever the strip of welting at the desired point and will thereby prevent waste of welting such as occurs where the welting is supplied in small pieces slightly longer than are necessary for the individual shoe.
