MACHINE FOR LASTING BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 329,367, dated October 27, 1885.

Application filed September 1l 1885. Serial No. 175,875. (No model.)

To all whom it may concern:

Be it known that we, J OsEPH E. CRISP, or" Boston, Massachusetts, and GEORGE W. COPE- LAND, of Malden, in the county of Middlesex and Commonwealth of Massachusetts, both being citizens of the United States, have invented new and useful Improvements in Machines for Lasting Boots and Shoes; and we do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature, of which- Figure 1 is a side elevation of our improved machine. Fig. 2 is a plan ofthe same. Fig. 3 is a section of Fig. 2, taken on line a: x. Fig. 4 is a section of Fig. 2, taken on the center line. Fig. 5 is a plan with the upper part-s and heel-support removed, showing the full operation of the toe-band. Fig. Gis an end elevation with the heel-support removed.

The object of our invention is to produce a machine by which the toe portion of the upper of boots and shoes may be readily drawn and turned down upon the insole by the aid of manual power only in any part of the operation preparatory to fastening the same, and which will require no adjustments for different sizes of the same style of lasts.

It consists of improved heel-supporting devices which hold and carry the heel so that the toe portion of the shoe is firmly held at the proper angle with reference to the toelasting plates, and which, without regard to the length of the shoe, can be locked in position by a lever always moving through the same are.

It consists, further, of an improved band of flexible material, preferably of leather or metal, for the purpose of securely holding the upper around the toe of the last, just below the lasting-plate, and operating from a point near or at the center of the toe, and while being drawn from such center toward and around the toe portion of the sides, and continuing by the strain it exerts upon succeeding portions of the upper which are subject to its action as it is caused to be drawn around the toe-upper to rmly hold the upper-leather against the last. As this band is drawn from the center of the toe to the sides of the last, it

will of course conform automatically to all shapes of lasts.

It consists, further, in improved means of changing the inclination of the boot or shoe, so as to promote the convenience of the operation.

In the drawings, A represents the body of the machine, which is carried and may be swung and secured at any desired angle by the stationary piece A', made fast to any suitable foundation. The top surface of this body is provided with slide-grooves A, in which move the sliding bars A3. These sliding bars A3, as hereinafter described, operate the band for pressing the toe portion of the upper against and firmly around the last. On the top of body A move the lasting-plates C. On one side of body A is secured the bracket A4, which supports and carries the heel devices, Figs. l, 2, and 4. The toe-lasting band b, Figs. 4, 5, and 6, preferably secured to body A at b', is a piece of leather or other flexible material formed with an ear secured to body A, as shown. The upper part of the band, which is drawn around the toe, may be of any desired width, and its two ends are secured to the small blocks b2, which connect them with the sliding bars A3, by the connections b, so that pressure exerted upon bars A3 is communicated to the ends of band b, as can be clearly seen by reference to Fig. 5, and results in drawing the band against and around the toe of the last. A spring may be attached to this band b to keep it open so that the largest boot or shoe toe will freely pass to the center thereof without touching the ends of the band. Close above the upper edge of the band b is located the toe-downhold C, which prevents the surface ofthe upper when turned over upon the inner sole from being forced by the heelsupporting device above the line of action of the toe-lastingplates. These toe-lasting plates C are connected to downhold C by and swing with the links Cz and C, C3 being provided with suitable handles, C, The length of the links C3 and C2 with reference to each other govern the motion of plates C so that its ends next to downhold C move in coincident lines with the angular ends of C and prevent any portion of the upper from getting between downhold C and plates C. The operating IOC ends of plates C are held down to their work by the curved plate G5, secured to bodyA by screws, as shown. There are also formed on the handles O2, that form part of the links C3, devices for operating the sliding bars A3, so that upon the forward motion of the handles C4 the drawing of the band b commences, continues, is finished, and held in position before the lasting-plates begin' to operate, and also while these plates are turning and holding the upper over and down upon the insole. This is clearly shown in Figs. 2 and 3. By reference to Fig. 3 it will be seen that the bars A3 are formed of two parts, a and a', pressed apart by the spring a2, and held from being pressed too far apart bythe rod a2 and pin a4. The connections b3 are pivoted to parts a and a5, and at a on a' is pivoted a swinging link, c, Fig. 2. The other end of this link cis provided with a round bolt-head, c', below it, which, so long as it is desiredto move a' forward, moves in the slide-grooves; but when part a. has reached the desired limit of forward motionbolt-head c'is swunginto thehalf-round cavity AX, Figs. 2, 3, and 5, and is there retained until the lasting-plates have been operated and returned back to the same position. During this operation the band b has been held against the upper with a force governed bythe strength of the spring a2. To move and swing at the proper time link c, the body of its bolt is prolonged so as .to reach far enough above link c to carry the roll c2, and .C4 is provided with a groove, C, that engages with the roll c2, moves it forward until roll c2 isopposite half-round cavity AX, when it, by reason of the change of angle C, passes into cavity AX, andis there held by the curved part of C4 Cl, and prevented from moving therefrom until C6 returns, when it passes back to its starting-point. This construction permits the'bandto be automatically drawn around -a toe of any size, and also enables the operator to move either one or both sides of the band up to and against the upper, as may be desired, before operating the lasting-plates.

The heel-supporting device holds the heel at the proper height with reference to the curveof `that part of the toe operated upon by the ,lasting-plates, and is constructed as follows: On'the bracket A4, at A5, is pivoted the ,lever D, Figs. l, 2, and 4. 0n lever D slides vthe half-round piece D', which can be adjusted'and secured to lever D at any distance from the center by the set-screw D2. The half-round piece D carries on its top the heelgage D4, against which the heel is raised before pressure is exerted upon it. To the ends of the-half'round piece D are attached the ends of a sling, D3, preferably of leather, of any convenient width, which embraces or hugs the back or counter portion of the heel. The pin E, made fast in lever D, passing through bracket A4, acts as a pivot, and has securely fastened to it the segmental ratchet F. Made -fast under bracket A4 is the strong spring G,

provided at G' with the fixed pin G2: Upon `pin G2 is pivoted the handle H and lever H',

which may be made in one piece, provided with the stop-pin h. To the lever H' is connected the pawl H2, provided with the stoppin h. v The lever H' is so proportioned that the motion of the point of the pawl H2 is somewhat more than the distance between the teeth of the ratchet F when the handle H is moved from stop 7L to stop h', and when. the stop k' is pressed against G the end of pawl H2 is raised above the teeth of the ratchet F, as shown by the dotted lines. To secure the boot or shoe by this apparatus, the handle H is pressed fully back and the ratchet F left yfree to swing with the lever D. The heel is passed into the sling and held up against the gage Dt. The lever-or arm D is then swung forl ward until the toe of the last is under the toedownhold G and against the center of the band b. Then the handle H is moved down. The pawl H2 drops into the tooth of ratchet F under it, and the full downward motion of handle H presses, holds, and locksthe-toe against the center of the band b ,and under downhold C with the desired force, which is communi" cated by the spring G. The band b and the lasting-platesl are operatedas before described.

It will be observed by reference to Fig. 2 that the leg portion of a boot can be passed sidewise into the machine, .instead of passing it downward, as is usual.

What we claim as new, and desire `to secure by Letters Patent, is-
