JAMES F. FULLUM, OF EVERETT, MASSACHUSETTS, ASSIGNOR TO THE FULLUM SHOE STRETCHER COMPANY.

SHOE-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 503,742, dated August 22, 1893.

Application filed March 7, 1892.

To all whom it mag/concern.

Be it known that I, JAMES FRANCIS FUL- LUM, of Everett, in the county of Middlesex and State of Massachusetts, have invented a new and useful Stretching-Last, of which the following is a specification, reference being had to the accompanying drawings, making part hereof, in which Figure 1 is an elevation; and Fig. 2 a plan of astretching last embodying all the features of my invention. Fig. 3 is a plan with a portion removed and a portion in section on line 8-3 of Fig. 1. Fig. 4 is a plan like Fig. 3, except that other portions are removed. Fig. 5 is an elevation, partly in section on line 5-.35 of Fig. 3; the shell and toe piece being in section on line 5-5 of Fig. 2. Fig. 6 is a sectional elevation showing a modified form of instep piece.

My invention relates to that class of lastsused in shoe stores mainly for easing shoes or boots to suit customers and the main feature of the invention is the combination with the body of a last of two pairs of levers, fulcrumed on the body of the last; two side pieces hinged each to the outer ends of a pair of levers; a slotted plate engaging pins on the inner ends of both pairs of levers, and devices for moving the slotted plate endwise.

My invention includes other features set forth hereinafter.

In the drawings A A are the two main parts of a hollow last, which with the uprights a a constitute the frame by which the moving parts are supported.

In the best form of my invention the cross rods 19 b serve as fulcrums for four pairs of levers; one pair (1 d to actuate the heel piece I); another pair ff to actuate the side pieces F F; a third pair g g to actuate the instep piece Gor G 5 and a fourth pair h h to actuate the toe piece H. The levers d and d are connected by toothed segments, and the lever d has a toothed segment at its lower end which meshes with the rack fast to the guide d of heel piece D; so that when the tang which forms the upper end of lever d is moved (by means of the socketed handle J applied as shown in Fig. 1), the heel piece is also moved; for motion of the upper end of lever d in one Serial No, 423,974. (No model.)

direction moves ,the lower end of lever d in the same direction, and the heel piece D moves in the same direction as the lower end of lever 11, the segment on the lower end of (1 being in mesh with the rack on guide d of heel piece D. The levers f and f are also connected by toothed segments so that when the lever fis moved the leverf is also moved; and the lever f by means of link f moves slide f which actuates through the levers f and f side piece F; and through levers f f side piece F. The studs which form the fulcrums for levers f f ff are fast to the sole of the last, as indicated in Fig. 4. The levers g and g are also connected by toothed segments, and lever g is connected by link 9 with lever 9 which actuates instep piece G. In some cases the instep piece should be corrugated on its upper surface, as indicated in Fig. 6, and I therefore make the instep piece so that one, G, can be readily re moved and another G used instead. 'lhisis done by making each instep piece with a tang which fits loosely in a socket g that socket being formed in a casting g which is rigidly secured on posts 9 fast to the sole of the last; and for greater stiffness also connected by screws g to sides of part A, as clearly shown in the drawings. Thelevers hand h are also connected by tooth ed segments, and lever h is connected by link It with lever 77. which is connected by link 71. with slide 72 which carriestoepiece H. In order to give toe-piece H a slight upward motion as it is forced outwardIform a projection 71 on the toe part of the sole of last A, and hinge toe piece H to its slide h. Each of the levers (Z f g and h is supplied with a pawl and ratchet as shown, when it is desired to hold the strain. The pieces A and A are shown as held together by the cross rods 1) b and screws 12 b in addition a screw b may be used on each side to connect piece A with A.

The side pieces F F are usually formed with one or more holes to receive the tang of additional pieces F so that the outer surface of either side piece can be varied as desired by shifting these additional pieces F When stretching the toe of a boot or shoe with my last the heel piece is first adjusted it bodily away from the last are also features of myinvention; a

So far as relates to construction, the last in the form of a shell with the cross rods each supporting a set of lovers, with their opposed ends, toothed segments and intermeshing, and the lower ends ofthe inner set of leverssuitv ably connected to the parts to be moved is a feature of my invention. And the shell last with the inner castingg fast to the sole of sub-combination which is a substantial: and material part of myinvention asv is the subcombination. of the levers g g link g -lever g and instep pieceG; and the sub-combination of leversh h, link 71, lever h link h. slideh and toe piece; a; and the sub combinationof levers d d, rac d andheel piece D.

What Irclainr as my invention is-e 1. In a' stretching last the combinationwith 7 the body of thelast of two pairsofi leversgful crumed on-l the body ofthe last; two side pieceshinged each totheouter ends of a pair, of leversg a slotted plate engaging pins: on theinthe rear portion of it; two sets of leverswith toothedintermeshing segmental parts; movable portions for stretching the desired parts of the last or shoe; and connections between the inner sets of levers and the movable portions; all substantially as described.

3. A stretchinglastcomposed' of three'main parts A A andg each substantially as shown,

and forming a hollow shell with an interior strengthening piece; movable portions for stretching the desired parts of the boot or shoe; and mechanism substantially such as is 5 described for actuatingthe movable portions; the hollow shell A A 'and'the interior strengthening piece g forming a frame for such mechanism; all substantially as set forth.

the last, and forming a frame for the instep I piece and for a portion of itsoperating mechanism is alsoa feature'of myinvention. Also the pair ot levers ff link f slide f 'lev-ers f*, f (orf f and side piece F (or F) are a;

t. In combination a last; levers f f link slotted slide f levers1f f ,f ,.f and side pieces F F all substantially asdescribedr 5.. In: combination a: last; lovers 9 gf; link :9 leverg andinst'ep piece G'; thelink g connecting lever-g with lever giand lever g f engaging the instep pieceG-g allsubstantlally as described. i

6., In-vcombinationa last; levers; h h; link k lever h 7; link h; slide hi; a-ndtoe piece H; the link h connecting lever h and slide k all substantially as, described;

7. In combination a last; segmental lever yd;- doublesegmental lever d; rack d and heel piece D; thel'ever d meshing-with the outer seg-rnentof lever'd', and theinner segn ment of lever d meshing with heel piece rack d all substantially as described.
