stress 225 /23", Franiifort-on-the-lviain, in

the German Empire, have invented certain new and useful improvements 111 Arrangev i 0 merits Binding uppers on the Last, or which the following is a specification.

The present invention consists in means bv which the ends .a string, servmg to bind the upper on the last. are passed through a stitching on the edge of 1 is upper and ien carried irom tne sole STlfi to the ridg o. e span, or through last. and be psi at. v

in the accompanying drawing Figur 1 shows the device before the ends of the string have been pulled taut, and 2- shows the device after the ends of the string have been pulled taut,

On a W011i supporting pillar having a foot 8 is pivoted on pin a double armed lever adapted to be held 111 the position shown in F 1, by means of a spring '7, secured to the Workbench r. 3*; its llOOkthe lever is coupled to a rod g, the ot.1er end of which is linked at ii, to a treadle go, which is journalcd in a bearing On pm n the lever on, is pivoted a saddle on", which is provided with iinobs 0, 03. This saddle m 'L er the action of a Spring cc, wnich is secured with i:lS other end is, to the part 722" lever This spring so will hold the saddle m close against the back of lever m.

last and the pu l ng string -whiel1 is strung through the st tching at e edge of the upper is passed through the bore in the last. For tightening the string, and thereby binding the upper a on the lee string a is caught around the knobs 0, corresponding to the respective length the string loop. If instance, the is of the length as shown in the g, is caught around the three upper obs 0, When tiie'treadle is pressed down, the red 9* will be likewise moved dOFFIllever m will be moved into .2. The spring i 5, i t

n she tension, l

consequence of the movement of leverm, the string 6 Will be likewise pulled downwardly, and the edge of the upper will be lipped over the last, so that the upper itself Will be drawn, at all points, smoothly over the last. At such taut position of the string, Fig. 2, a plug n is introduced into the bore 7 on the ridge of the last, so that the string. 6. can not slacken. When the treadle is released" by the operator, the levers m, m, m will return under action of spring 1, into their initial positions, Fig.

1, the strings will be disengaged from the knobs 0, 0 or may be taken off from them, the lost is taken ed the stem 5 and the shoe can be finished in the usual manner. in order to prevent the string from being broken, it the treadle should be suddenly and forcibly pressed down, a spring w is interposed between the movable part m and he arm m or lever m. If a sudden pull is now exerted, the saddle m Will, as shown in Fig, by dot-and-dasli lines lift from the lever m, stretching the spring w so as to avoid breaking the string 6.

We claim:

l, The combination with a last having an opening therethrough for the passage of a lrn'w string for the upper, of a support for last, lever mounted on the support, ienns movably mounted on the lever 'az l adapted for connection with the draw stmg, nd n yielding connection between said means and lever, substantially as and for tliepurpose set forth.

2, The combination of a last having an opening tberethrough for the passage of the draw string of the upper, of a support fer last, a lever mounted on the Suppl a saddle pivoted on said lever and adapted for connection with the draw string, and a spring yieldingly connecting said saddle with the lever, substantially as and for the purposes set forth.

"in a device for binding uppers on the last by drawing the binding string through said last, the combination with a standard adapted to receive the last, of a lever fulcruined on said standard; another lever fulcrumedcn said first lever and adapted to be csci'llated parallel to the same; projections extending laterally from said other lever and adapted to receive the string employed in binding the upper on the last; means for operating the said first levers, and means for returning them automatically to their position of rest.

i. In a device for binding uppers on the last loy drawing the binding string through said last, the combination with a standard adapted to receive on its top the last with the upper and the string projecting from the bore in or near the ridge of the span of the last, of a lever fnlcrumed on said stenderd; another fulcrumed on said first lever and adapted to he oscillated parallel to the same; a plurality of knobs extending let-- erally from the said other lever at various distances from the last and adapted to hold.
