Specification forming part of LettersPatent No. hdth,265, dated June 24, 1873; application filed May 6,

To all whom it may concern:

Be it known that I, CHARLES W-GLIDDEN, of Lynn, in the county of Essex and State of Massachusetts, have invented an Improved Lasting-Machine; and I do herebydeclare that the following, taken in connection with the drawings which accompany and form part of this specification is a description of my invention sufiicient to enable those skilled in the art to practice it.

The invention has particular reference to that class of lasting-machines employing flexible sacks or bags for receiving the upper and last and pressing the edges. of the upper beyondthe face of the last, water or other fluid being forced into'the bag to expand it against the upper, the invention being, however, more or less applicable to other lasting-machines.

In my invention I combine with the matrix or box that receives the last and upper a reciprooating slide having a nail-tube, which,

by the advance of the slide, is carried over the edge of the upper (pressed over the last bythe end of the advancing slide) and. under a driver having a downward movement that drives the nail, the retreat of the slide preferahly bringing the tube under a nailsupplying tube, from which the nail drops or is forced into the nail-tube of the slide.

My invention consists in such an organization and in details of construction and arrange ment of mechanism pertaining thereto.

The drawing represents a machine embodying my invention. Figure 1 shows the machine in side and sectional elevation. Fig. 2is a plan of it, Fig. 3- is a front view, the last-- supporting mechanism being removed.

a denotes a bed-plate having a pedestal, b,

in the upper part of which .is mounted the upper-crimping and nail-tube slide and the nail-supplying anddriving mechanism. 0 den'ntesia pin or support pivoted to the front end of a weighted loveryd, and having mount ed upon it a yoke, e, to the two arms of which is pivoted the box f that receives the last and upper, the last being preferably supported upon pins 9 extending through the box, and from an arm, h, forlnigig part of the bOxframe. W hen this box is to containthe flexible bag, (or a flex" e lining with a fluid space behind it) suitable inlet and. discharge tubes are provided for injecting the iluid into the bag and permitting it to escape therefrom, as in other machines using such bags. The top plate j of the box is in or nearly in the plane of the top of the last, and beyond the rim 5 is a flange, 70, forming, with the rim i, a groove, :2 into which extends a guide-roll, l, or a pin projecting from the ,head or, the rim 4 being pressed up against the roll by rolls 1;, or pins extending from slides n, that slide in the head and are "forced forward by springs 0. The projecting part of the box under the groove rests upon a button, g; which button extends from a vertical slide, 1*, that .is pivoted to. a foot-lever, s, pressure'u on the outer end of the lever lifting the slid and button and the button holding the flange up to the erimper and nail-tube slide. -t denotes thecrimper and nail-tube slide, moving horizontally in the head, m and having at its rear end a slot, u,

'to a foot-lever, y, and has on opposite sides inclines 2, one of which, as the bar is raised by the lever,presses-forward the crimper-siide t, and the other,as the bar falls drawing back said crimper-bar. In the front end of the crimperslide is a nail-tube,-u which, when the slide is drawn back, is directly under a tube, b through which the nails or nail-wire passes into the tube, and as the slide moves forward this tube with its nail is brought under a driver, c and over the edge of the upper, which, by the movement of the crimper-slide, is pressed over the edge of the inner sole laid upon the last. This driver slides vertically in a bearing at the front .of the head m, and is connected to the front arm of a lever, d wnose rear arm extends over the bar 10. As the bar rises the tube charged with a nail is driven forward, and when the nail-charged tube has reached a position directly under the driver the bar strikes the lever, forcing down the driver 0 through the tube, and driving groove, the pins or rolls 1) p pressing against the roll I, and the button qpressing the flange k up to the pin, all substantially as shown and described. v v

5. In combination with the crimper-slide t, and with the driver 0 the bar in for imparting the forward and back movements to the slide and the downward movement to the driver, substantially as described.
