`VT07 all wltom t may concern:

Be it lmown that I, GEORGE H. BLACK,

a citizen of the United States, residing at Rochester, in the county of Monroe' and Stateof New York, have invented certain Improvements in Fastening-Inserting Machines, of which thev 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 to fastening inserting machines and particularly to machines organized for use in shaping the work and preferably then applying a fastening to secure the work in its shaped condition. The invention has been applied with commercially advantageousresults to the production of shoe insoles and particularly to the production of an insole which constitutes the subject-matter of a co-pending application Ser. No. 201,372 filed by me on even date herewith.

A feature of the invention consists in the combination of fastener inserting mechanism with work supporting means and work shaping means arranged ,to force a portion of the work into a predetermined relation to the body of the work and hold it in operative relation to the fastener inserting mechanism. This feature of the invention is herein shown as embodied in a work supporting table comprising a clenching surface .over which an insole may be moved in the act of presenting the insole to the fastening mechanism, :combined with a shaping member constructed and arranged with relation to the table and insertingmechanism to engage the upstanding lip or sewingI rib of an insole duringthe movement of the insole into position to be operated upon and by such arrangement to bend the insole lip inwardly away from the edge of the insole and hold itin such bent position, while the fastener inserting` mechanism drives a fastener in vposition to sec-ure the lip in its bent over position against the outwardly directed strain of the inseamlwhich ispto connect the ,shoe upper to theinsole. Other features of theV invention includingcertain details of construction and combinations of parts will appear from the following description .of an 'illustrated embodiment of the invention and will then be pointed out in the claims.. `r

Fig. 3 is a transverse sectional viewthrough an insole and the machine work table illustrating the operation of the machine.

The tack driving-.mechanism herein shown for illustrative purposes and which has been demonstrated to be commercially advantageous to use is of the type known in the trade as the Boston tacker, an example of lwhich is illustrated and described in United States Letters. Patent No. 389,275, Woodward. This mechanism comprises tacksupplying means and tack driving means-including a movably supported nozzle 2 and a connection between said nozzle and a tripping mechanism so arranged and organized that upward movement of the nozzle by the work will operate the tripping mechanism to cause thepower to be applied for inserting a previously separated fastening and for i' vertically movable work table operated by a treadle 5 to move the work intoy contact with the nozzle and then lift the nozzle to cause the tripping action above described. y

As herein illustrated the work table 10 is constructed andarranged with the top surface suitable for supporting a welt shoe insole and allowing the insole to be presented by a sliding movement .backwardly over the table. Associated with the table and overlying the rear portion thereof is a forwardly projecting spring plate 12 spaced above the surface of the table sufliciently to enable the feather portion o f the insole to be thrust under the plate. The front edge of the plate is shaped ,and arranged to engage the usual upstanding sewing rib of the insole and to crowd' and bend said rib inwardly away fromthe edgeof the insole. Said plate also preferably has an opening 13 located under the nozzle 2, the plate thereby presenting a construction initially engaging theI sewing rib throughout the width of the plate and during the tacking operation engagingthe rib on either side of the tack nozzle to hold the lip in inwardly bent position adjacent to the tacking point. The spring plate is spaced above the work table by a block 14 which also preferably constitutes an edge gage to limit the insertion of the insole under the nozzle to such a position that the tack will be driven through the inwardly bent rib and into the body of the insole in suitable or desired relation to the root or base of the rib to adapt said tack to hold the rib in its inwardly bent position during the sewing of the inseam and to assist in maintaining` said rib in such aV position against the outward strain of the shoe upper after the inseam has been sewed. The plate l2 and block 14 are held in place on the table l0 by a bolt 15, the bolt holes in the plate'and block being elongated to allow said parts to be adjusted relatively to each other and to the tack nozzle 2. Preferably the spring plate will be constructed and arranged to force the rib inwardly on-that side of the tacking point which is the more remote from the heel end of the insole and to assist the operative in positioning the insole longitudinally so that the tack will be inserted immediately back y of the point where the last inseam should be'taken, or at the extreme rear end of the inseam. The

object Vof this arrangement is to obtainY the maximum efficiency lof the apparatus in shaping the rib in the rear part of the shank andof the fastening tack in holding the rib in its inwardly bent position and yet have the tack where it shall not be an obstruction to the needle in inserting the end stitch of the inseam. The tack thus properly located is used by the` inseam sewing machine operative to determine the point atlwhich the inseam shall be begun or terminated. It isdesirable to bend inwardly and fasten vthe insole rib at both the inner and outer sides of the shank of the insole and in practice an operative presents the insole and shapes and fastens the rib on the one side and then takes out the insole and turns it around and shapes andv fastens'the rib at the other side. Inthis use of the machine the heel vend of the insoleis pointing to the l right in one case and to the leftl in the other case. The rib bending and work gaging device is Ytherefore symmetrically formed with relation tothe nozzle opening to contribute to the production of uniform results at the two sides ofthe insole. It is obvious that the instrumentality which gages the position of the insole tolocate the tack at the right distance inwardly from the edge ofthe insole may bev integral with or separate from therib bending means and may be adjustable with relationv thereto to provide as above described orv otherwise, fory example, for workingzupon insoles having different widths of.feathers, and ythat the instrumentalityby. the aidof which the work ispositio-ned' longitudinally of `the in.-

sole may be integral with or independent of means is herein shown as a spring plate and has` beenY referred to in this description for identification purpos'es'as av spring plate but it isobvious that no limitation in this respect is intended by the use of this expresslon. Y

The fastening ,employed for securing the lip in its bent down position is shown asa short slender tack which is inserted through the lip and into the body of .the insole vand preferably is clenched on. the lower face* of the insole, but other suitable fastening means may be employed. ,In the use of the machine the sewing rib ofthe insoleis bent inwardly and is subsequently compressedin its inwardly bent position between the work table and the nozzle and thereafter the tack driver applies a blow to the inwardly, bent to secure by Letters Patent ofv thellnited 'i States Y l l.
