.SBLEGIFICATION forming part of Letters Patent No. 659,399. dated October 9,1900. Application filed January 18, I900. Serial No. 1,828. (No model.)

To all whom it may concern: Be it known that we, CHARLES S. J OHNsON and WILLIAMS S. JOHNSON, of Lynn, in the county of Essex and State of Massachusetts,

a wooden last may be accurately positioned and suitably supported to have its sole lev eled or bea en out by pressure applied by a rolling form. In beating-outmachines wherein the work is done upon a shoe while upon its last and by heavy rolling pressure it has been found difficult, if notimpossible, to level shoes upon the wooden last upon which they have been made on account of the danger of breaking the last. It is, however, desirable for many reason's'that the shoe should beso leveled; and our present invention relates particularly to improvements in a last or jack support and its relation to the machine itself, whereby danger of breakingthe last is done away with and a certainty of good work being done is obtained.

Our invention also includes an improved device whereby the position of the shoe with reference to the rolling form may be accurately determined. In wooden lasts in common use no special pains are takento secure any precise location of the hole in the heel part of the last to receive the jack-pin, and consequently with the lastwsupport or jack in a given position the position of the wooden last with reference to the form may vary considerably, owing to the inaccuracy'in the location of hole above mentioned.

'Our present improvement further includes a device whereby the last may be accurately mechanism for operating it as seems neces-' sary to clearly understand the nature of our improvements.v Fig. 2 is a plan view of a device for'determining the position'of the shoe with relation to the form, as will be hereinafter more fully described. v

In the drawings, A represents the form, which by means of suitable connections with a revolving crank-shaft is .adapted to roll longitudinally over the sole of the shoe to be leveled in opposite directions.

B represents the last, which is supported upon a jack C.- This jack may be of any well -known construction, the form shown in the drawings being one commonly employed. The jack above described or any other form of jack which it may be desired to use is mounted upon a slide 0, adapted to slide in and out upon a platform or table D. 'This platform is in turn supported upon springs E, which rest upon thebase-plate F, which base-plate is adjust ably but firmly held in the bed G of the machine by means of rods H, sliding in suitable apertures therein. Vertical adjustment of the bed-plate is obtained by means of a screw'and nut I J or other suit-able device for the purpose.

The platform or table D, in addition to being supported by the springs E, which rest upon the base-plate F, is also inv pivotal slidlng connection therewith. This connection, as shown in the drawings, is formed by a plunger K, adapted to slide vertically through the hub L, made integral with or otherwise secured to the base-plate F. To this plunger the table D is pivotally secured, as shown at M. As thus far described, it will be seen thatthe device is adapted, first, to hold the last and shoe up to a point wherethe rolling form will come properly in contact with all parts of the sole to level the same, and, secondly,

to yield sufficiently to give sufficient pressure for the operation of proper leveling without breaking the wooden last. These results are due to the fact that by means of the devices described the last, while free to tilt by reason of the pivotal connection M and to rise. and fall by reason of the sliding connection K L,

proper movement by the base-plate F being fixed in place, as described.

is still held in place against other'and im- IOO An additional, though not, it is believed, an essential, feature of the device above described consists in connections between the base-plate and the last-table, whereby the supporting-springs E may be kept at all times under suitable tension and in proper relation to the table D. Suitable connections for this purpose are formed by rods N, located centrally within the springs E and pivotally secured at one end to the table F and at the other entering boxes d on the outer side of the table D. These rods N are suitably threaded on their upper portions to receive nuts, whereby the table D will be limited in its upward movement, while the spaces in the boxes permit of its further downward movement, as above described.

In order to secure the correct location of the last with reference to the travel of the form, we provide a last-stop O, of peculiar construction. It will be understood that the jack carrying the last is ordinarily slid over the jack-table D longitudinally into and out of its position of operative relation to the form, and this last-stop O accurately determines the proper position of the jack by abutting against the last and determining its proper position irrespective of the location of the hole in the last. This stop 0 consists, in its preferred form, as shown at Fig. 2, of a series of projections P of varyinglengths corresponding to the various sizes of lasts which the machine is intended to receive. These are attached to a hub, which is adapted to be revolved upon a post Q, supported upon the jack-table, this hub being adapted to be held in place, with its spur of proper length opposed to the back of the heel of the last with the shoe upon it, by means of a springtinger R entering a corresponding notch in the hub.

It will be understood that in machines of this character a single form is adapted to operate upon a number of different sizes of lasts. In the drawings we have shown the stop 0 as provided with seven projections of varying lengths adapted for use with seven consecutive sizes of last.

We claim-- 1. In a beating-out machine operating by rolling pressure, a yielding last-supporting device comprising a fixed base-plate, a jackplatform restingon springs carried by the said base-plate, andasliding and pivotal connection between the said platform and baseplate, whereby the platform may move pivotally in the direction of its length, and also vertically toward and I away from the baseplate, for the purpose set forth.

2. In a beating-out machine operating by rolling pressure, the combination with the last and its supporting-jack of a last-stop having arms or projections of different lengths to properly position the various sizes of last when upon the jack with reference to the operative position of the rolling form 3. The improved last-stop herein described, consisting of a hub having spurs or projections of varying lengths corresponding to the sizes of last employed, a post or pin upon which said hub is supported and adapted to be revolved, and means substantially as described for locking the said hub in any desired operative position as set forth.

In testimony whereof we have hereunto subscribed our names this 6th day of January, 1900.
