The'eyeinthe'platefl is" large enough to receive the head of a shoe eyelet and is flared outwardly to present a lower edge adapted to engage the head of the eyelet close to the shoe upper to permit the shoe, fly to be pulled or stretched with the aid of such engagement. Depression of the treadle 30 first raises the head 40 which is toothed 011 its upper face, to clamp a shoe fly which has been inserted under the plate 42 with an eyelet within the eye of said plate, the spring 35 yielding to permit the movement of head 40. A substantially greater forceis required to move the plate 42 upward against the resistance of spring 415 and therefore opportunity exists for the workman to manipulate the shoe to stretch the upper while he holds the fly gripped by the treadle. This he does by rocking the shoe and its contained last, causing the last to fulcrum on the bar or work rest 38,v

or it may be, on fulcrum posts 46 which are suitably supported for this purpose on either side of the gripper 40, 42. Having turned and fulcrumed the shoe as observation shows to be required to pull the upper and it may be to stretch it for removing any fullness that may exist in the region of the waist of the shoe, the operator further depresses the treadle to overcome spring 45 and carry the fulcrum bar 38, the gripper and the shoe upwardly and engage the tripping nozzle and cause a tack to be inserted through the eye in the plate 42 and through the eyelet in the fly and into the last to maintain the upper taut until the last is withdrawn during which time it sets or acquires permanently the shape given to it on the last.

Theinvention is shown in Figs. 3 and 4. as employed in the manufacture ofstitchdown shoes of which the uppers are molded at the toe and heel and are stitched to the innersole before the last is inserted. The insertion of the last and the subsequent shaping of the upper to the last constitutes the lasting of these shoes and the operation of this machine is particularly effective in shaping orlasting the waist portion of these shoes which frequently require care 'to'get the upper free from fullness and to stand up to the shape of the last from the shank and forward portion of the heel seat upward to the shoe fly. By pulling the stock upward the middle portion of the in.

'nersole, as well as the upper is drawn snugly to the last where it is fastened by thetack driven through the eyelet, or it might be through a buttonhole or through any portion of the fly including the ankle strap of so-called ankle ties and other low shoes or slippers, and held while the shoe sets or acquires permanently the shape of the last and the stock dries more or less in that shape. t .Q a t eat se tt a ma is that the operator works with the portion of the stock being manipulated plainly within sight and he can turn or vary the line or lines of strain to suit the existing conditions in each particular shoe and pull or draft the upper into desired shapeliness.

It is to be understood that this invention is not limited to use upon stitchdown shoes but may be used with good results upon other kinds of shoes.

It will be noted that this invention provides, for the first time as I am advised, means whereby a shoe upper may be pulled in the direction away from the shoe bottom and securing the pulled upper.

Having explained the nature of this invention and described a preferred construction embodying the same, I claim as new and desire to secure by Letters Patent of the United States all of the protection to which this invention is entitled and the following claiming clauses are to be construed to give effect to this purpose.

9. A waist lasting machine having, in combination, means to engage the fly on one side of a shoe, means arranged at one lateral side of the engaging means in position to permit fulcruming of the opposite lateral side of the shoe thereon for pulling upwardly the side of the upper engaged at the fly, and means for securing the pulled side of the upper while the shoe is in such relation to said other two means as to maintain the pull on the upper.

10. A. waist lasting machine having, in combination, means to engage the fly on one side of a shoe, means arranged to permit the fulcruming of the opposite lateral side of the shoe thereon for pulling upwardly the side of the upper engaged at the fly, and a tacker to which the engaging means is movable to carry the shoe into relation to the tacker for the taoker to insert a tack in position to secure the upper under tension at the waist of the shoe.

11. A waist lasting machine having, in combination, jaws recessed on their stock engaging faces to clamp the shoe upper around the upper and lower ends of an eyelet set in the fly on one side of a shoe, and
