Be it known that I, VVILUAM C. MEYER, a citizen of the United States, residing at; .lleverly.. in the county ot' Essex and Sta-te ot 1 filassachnsetts, have invented certain new and *i etui Improvements in Sewing-Ha chinos; and I. do hereby declare the following to a t'ull, clear, and exact description oit the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to shoe scwi ing machines of the class which are used in the manufacture of shoes to secure together the welt upper and insole. .Machines of this are known in the art as welt sewing machines.

The object of the invention is to improve the construction and operation of Twelt guides for machines of the class re" terr th this object in view the invention itt "consists Iin the constructions, arrangements and combinations of parts hereinafter described. the advantages of which will be obvious to one skilled' in the art from the follmving description.

'in the. drawings illustrating the pret'cricd torni oi the invention,- Figure 1 is a side elevation of a portion' of a sewing machineembodying the invention, certain thereof. being shown in section.; Fig.. .s aedcta'il plan view of the welt guide detached; Fig. l is a side elevation of the parte shown in Figi 2; yand Fig. 4 is a secf tional view taken on the line 1 -i of Fig.2 looking in the direction of the arrows. `The machine, a portion oi which Vis illustrated in thedrawingmds a welt sewing Only so much ci' `the machine as is necessary for an 'understanding of the present invention has been illustrated in the draw1 ings.' i

The stitch forming mechanism of the machine illustrated comprises a curved hook needle indicated at 1, an awl 2, a looper 3, and althread arm v i The we ,t guide .indicated at 5 comprises a hcdy portion or vframe 6 and n shea5 metal er shield 7 secured to the frazioe, the irameand die shield being constructed and wnnged in the usual manner to provide a f iorward welt engaging surfaces of the frame and the shield are Curved so as to give the desired transverse cuiwature to the welt. At the end of the frame is a shoulder or abutment to engage the inner edge of the welt. VThe outer edge of the welt is en gaged by a gagel indicated at 9 which is arranged for adjustment widthwise of the welt guiding passage in order to guide welts of varying widths. In order to provide for the adjustment of the said gage, the gage is formed with a screw threaded shank 10, arranged to move in a guide bore 11 in the frame 6 and engaged by an adjusting nut. 12 arranged in a slot 13 in the frame. The gage 9 may be adjusted in any -desired position widtnwise of the welt guiding passage by turning the nut 12. In order to hold the gage in adjusted position a bent leai'I spring 14 issecured to the frame by means of a Vscrew 141a and is arranged to frictionally engage the 'milled peripheral surface ofthe adjusting nut 12.

free end of the welt is indicated at. 16. This Aholding device consists of a finger pivotally mounted .on thewelt guide by means of a pivot screw 17 and provided at its forward extremity 18 with a welt engaging point. The point of the welt holding linger is preferably arranged vto engage the groove in the welt adjacent the free end thereof and immediately in advance ofthe sewing point as illustrated in Fig. 2. At the beginning of the. sewing of the inseam after the welt is inserted in the welt guide with the free end of the welt projecting slightly in advance of the guide, the welt holding linger is moved forward by the operator to carry the point thereof into engagement with the welt. The 'free end of the welt is thereby held in position to be attached to the upper and insole. When the feed movement of the Work has begun, the movement of the welt through the welt guide will cause thewelt holding finger to move about its pivot in a direction to release the point thereof from engagement with the welt. The welt holding device is thus automath cally operated to release the welt. 'It will be noted 'that when. the welt holding device is in operative position in engagement with 'the welt that any movement of the welt in .i guiding passage between them. The

a direction to '"raw the free extremity A welt holding device for holding the' guide will cause-the Welt 1. A Welt sewing machine having, in com-v hlnatlon, stitch forming mechanism, a Welt guide comprising a frame and a shield, a
