JOSEPH B. JOHNSON, OF LYNN, MASSACHUSETTS, ASSIGNOR, BY MESNE ASSIGNMENTS, OF ONE-HALF INTEREST TO ARTHUR FULLER.

IMPROVEMENT IN MACHINES FOR SHAPING THE SOLES 0F BOOTS AND SHOES.

Specification forming part of Letters Patent No. 75,428, dated March 10, 1868 June 24', 1879; application filed February 10, 1879.

To all whom it may concern:

Be it known that I, J osnrn B. JOHNSON, of Lynn, in the State of Massachusetts, have invented certain new and useful Improvements in Machines for Beating Out the Soles of Shoes or Boots, the same being fully described in the following specification and in the accompanying drawings, of which- Figure 1 denotes afront elevation; Fig. 2, a

side elevation, and Fig.8 avertical and transverse section.

The present machine may be said to be an improvement with reference to the subject of Letters Patent granted to me November 26, 1867.

My invention consists, principally, in adapting a last, suitably supported, not only to receive a powerful pressure, but to be easily withdrawn therefrom andfrom the mold, to enable a shoe to be removed from the last and another placed upon it.

In the drawings, A denotes the sole-mold, which, inthis instance, is connected-with the head a of a press by a screw, as, there being between the head and the mold a plate, b, of vulcanized india-rubber, against which the mold bears; The screw goes through a hole in the head somewhat larger than the diameter of the screw, so that with the aid of the clastic bearing the mold may conformitself to a sole under pressure. The head a is arranged above a base-bar,"c, and is connected therewith by two parallel and vertical rods, 11 d, as repof slid'ing vertically freely toward and away from the head. This bed is connected with the bar a by a system of toggles, ff 9 g, which,

at their central join t, are connected with a pair of auxiliary toggles, h i, which are jointed to a bar, k, which is supported by and slides a bar k, and by means of a pitman, n, is joined to a treadle-lever, 0, arranged as represented. The auxiliary toggles, at their middle joint,-are

bed, 0, extends between the two. .mds,--and is fitted to them so as to be capable Reissue No. 8,776, dated connected with another such treadle-lever, p,

port, u, connected with the bed 0 of the chine, its primary object being to carrythe last to position beneath the mold, and to enable it to be withdrawn at the will of the operator. This support will, by a revolving or an alternating movement thereof, place the last under the mold and withdraw it therefrom, to

enable the pressed shoe-sole to be removed. As the support rests on the bed 0, and is capable of being revolved horizon tally on center or axis d, I am enabled, by making it of a length necessary for the purpose, to use a last, 1), as an auxiliary to the main last u, so that while a shoe on the main last is under pressure an-.

other may be placed on the auxiliary last.

In connection with the support there .is a

.stud,a', which operates with a springJatch, b,

on the bed 0, in such position with respect to the mold as to lock thelast in its proper position to receive pressure. Each lastis provided on its sole with an elastic facing, as shown in the drawings, consisting ofa seat or cushion, y,'of indie-rubber, over and upon which is "a thin metallic: plate, z, having the' form of a sole.

The advantage of having the last so applied to the support as to be capable of beingrevolvedon an axis falling vertically through the last,

and auxiliary treadle with the two sets of toggle-jointed levers and their pitman and operative treadle enables the or extending from it, is that itfen ables the workman, prior to the removal of shoe from the last, to turn the latter about into the most convenient position for effecting such removal. The employment of the wedge, the

' slotted slide-bars,

operator to regulate by his foot the amount of pressure exerted by the toggles on the last and .mold.

I claim- 1. In a niaehinefor beating out the soles of boots or shoes, at last-carrying support combined with a bed, mold, and press, substantially as set forth, whereby the relative position of the last and press may be'changed in a plane transverse to the line or direction of A the press by means substantially as described,

or the equivalent thereof, whereby such mold is enabled to adjust itself to the sole of the shoe while under pressure.

6. A last provided on its sole with an elastic facing, substantially as set forth.

T. The elastic facing consisting of an indiarubber cushion and a metallic face-plate, ill combination with-the last, substantially as set forth.

S. The combination of the slide-bar 7;, the wedge m, and the auxiliary treadle-lever 0 with the toggles and .their operative. pitman and treadle-lever.

9. The combination of the bed e'with the support for carrying the last, and the device for stopping the support in position beneath the mold, substantially as shown.

10. A last having a base extended toward the toe, substantially as described.

JOSEPH B. JOHNSON.
