LASTING-MACHINE.

SPECIFICATION forming part of Letters '.Patent N o. 570,220, dated October 27, 1896.

Application filed Tulle l, 1896, Seltl N0. 593,744- (NO model.)

To all whom it muy concern:

Be it known that l, WILLIAM S. HAMM, of Newton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Lasting-Machines, of which the following is a specification.

The present invention relates to machines for lasting over the heel and toe portions of boot and shoe uppers, and has in view, for one thing, a more convenient manner of adjusting the machine to dierent styles of lasts, so as to bring the bottom of the last at the toe end parallel with the plane of movement of the Wipers.

A further object is to provide improved means whereby the operator can raise and lower the heel and toe rests at will.

To the above ends the inventionconsists in a number of novel combinations of parts, which are recited in the appended claims.

The drawings which accompany and form part ofV this speciiication illustrate an embodiment of the invention.

Figure l shows a front elevation of the machine. Fig. 2 shows an end elevation of the same. Fig. 3 shows a top view of a portion of the machine. Figs. 4 and 5 represent, respectively, sections on the lines 4 4 and 5 5 of Fig. Figs. 6 and (5 represent sections on line G 6, Fig. 3.

The construction of the wipers and the means for operating the same form no part of the present invent-ion, and will not, therefore, be described.

'The letter a designates the main supporting-column of the machine, which rises from a suitable base d and has mounted on its upper end the toe-lasting mechanism, comprising a fixed frame or support Z9 and toe-wipers L b', aiiiXedto a slide b2, which is movable in guides on the support b, a lever b3, pivoted at b4 to the support b and at b5 to the slide b2,

serving to enable the operator to move the wipers forward and back, the Wipers being thus alternately projected over the last and retracted therefrom at the will of the operator.

The frame c, which supports the last o and heel-wipers, which are movable thereon by means similar to those employed for operating the toe-wipers, is pivoted at its inner end to the frame b, as shown at c', and is adjustably supported at its outer part by the following-described means: A screw d is pivotally connected at oneend to the said frame c, and a sleeve e receives its opposite end loosely, said sleeve being pivoted to the column a. A wheel f engages the thread of the screw, and its hub bears against the upper end of the sleeve. Now by turning said wheellthe frame c can be raised or lowered, and it is by this means that I secure the proper relation between the toe-lastin g wipers b and the top portion of the last by making the forward portion. of the bottom of the last substantially parallel with the path of movement of the toe-wipers. The frame c requires to have a greater inclination when the bottom of the last has a considerable curvature than when it is approximately iiat. It will be seen that movement of the frame c on its pivot changes the relation of the plane of the bottom of the toe part of the last to the general plane of the frame b, and in this way the traverse ot' the toe-wipers in a plane parallel with the toe-bottom is insured.

The heel part of the last o is supported by a heel-pin g, which is secured to a bracket g', depending from the frame c, and is jointed as usual to permit the last to have a universal tipping motion. The heel-pin gis fitted to slide in the bracket g', and rests on a lever g2, pivoted to the bracket and connected by a rod g3 with a treadle g4. A spring g5 is attached at one end to said lever on the outer side of its pivot and at the other end to the frame c, and said spring exerts itself to de-` press the end of the lever on which the heelpin rests. The operator, by working the treadle g4, can raise and lower the heel of the last at will.

Between the heel-pin g and the wiper-support b is interposed an independently-movable toe-rest h, which is adapted to be raised and depressed by the operator, so that the toe portion of the last may be first raised to cause the wipers b to first impinge on the upper below the bottom of the last, as shown in Fig. 6, and then lowered to permit the wipers to project over the bottom of the last,

as shown inFig. 7, it being desirable to re IOO peat this movement several times in lasting each upper'.

rllle toe-rest 7L is fitted to a block 7L', having a stem 7a2, iitted to slide through a bracket h3, fastened to the column a., and said stem is connected by a link h'L with a rod h5, jointed at its lower end to a treadle 7L, the arrangement being such that depression of the treadle causes depression o't' the toc-rest. A lever i connects with the link 7L at one end and is pivoted to the column, and at its outer end connects with a rod t', which is jointed at its lower end to a treadle f1?, the depression of this latter treadle, it will be observed, causing the toe-rest to rise. A springj, surrounding the stem h2, exerts itself to keep the toerest elevated.

The operator, by placing his heel on the treadle h6 and his toe on the treadle i2, 'can readily control the toe-rest and move it up and down at will.

I do not limit myself to the described means for raising and depressing the toe-rest, and may employ any other suitable means whereby the operator may quickly raise and depress the toe-rest at will.

To hold the toe portion of the last firmly upon the toe-rest 7L, I provide a clamp p, which is movable with the toe-rest and is arranged to bear upon the bottom of the last at a point near the toe, as shown in Fig. 3, said clamp being adjustable independently of the toerest, so that it may be pressed upon and raised from the bottom of the last.

It will be understood, of course, that the clamp p actually bears upon the inner sole, and not directly upon the last. The said clamp is an arm or linger formed upon a vertical shank p', which is movable vertically in a socket p2, formed on or afxed to the block 71.', which supports the toe-rest 7l.. A spring p2 in said socket normally raises the clamp p from contact with the last. rlhe lower portion of the shank p' is provided with serrations p, which are engaged by a springpressed detent 2f, adapted to hold the clamp at any point to which it may be depressed against the pressure of the spring. Then the clamp is pressed downwardly, the detent p5 retains it at the point to which it is thus pressed, and when the detent is displaced the spring raises the clamp.

I claiml. In a lasting-machine, the combination with toe-lasting devices including movable toe-wipers, of a last-support, a toe-restinterposed between the said last-support and lasting devices, and means for reciprocating the toe-rest in a direction substantially at right angles with the direction of movement of the said toe-wipers.

2. In a lasting-machine, the combination of toe-lasting devices, a last-support, a toerest interposed between the said last-s upport and lasting devices, means for raising and depressing the toe-rest, and an adjustable clamp movable with the toerest for holding the last upon the toe-rest.

3. In a lasting-machine, the combination of a fixed wiper-support, a pivoted last-supporting frame, and means for raising and lowering said frame, for the purpose described.

et. In a lasting-machine, the combination of a stationary support for toe-lasting de vices, a frame pivoted to said support and having a bracket supporting a l1eel-pin, and means for raising and lowering the frame, for the purpose described.

5. In a lasting-mael1ine, the combination of a stationary support for toe-lasting devices, a frame pivoted to said support and having a bracket supporting a heel-pin for the last, a toe-rest adjacent to the pivot of the frame, and means for raising and lowering the frame,substantially as and for the purpose described.

G. In a lasting-machine, the combination of a stationary support tor `toe-lasting devices, a frame pivotally connected with said support and holding the last, a screw jointed to said frame, la sleeve or socket jointed to the stationary support, and a hand wheel or nut engaging the screw `and bearing against the end of the sleeve.

7. In a lasting-machine, the combination of a toe-rest vertically movable in a suitable support, and two treadles connected with said toerest through different mea-ns, whereby depression of one treadle lowers the toe-rest, and depression of the other treadle elevates the same.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 26th day of May, A. D. 1806.

XVILLIAM S. HAHN.
