`ITED i PATENT, OFFIUE;

HARRIE A. BALLARD, or BoSToN, MASSACHUSETTS, ASsIerNoiiv To THE BoYLSToN MANUFACTURING COMPANY, or SOUTH BOSTON, MASSACHUSETTS, A CORPORA- TION OF NEW JERSEY.

T0 all whom t may concern:

Be it known that I, HAnnin A. BALLARD,`

of Boston, inthe county of Suffolk.. and State ot' Massachusetts, have invented cer-- tain new and useful Improvements 1in `Divided Lasts, of which the following` is a specification.

This invention hasrelationto lasts suoli as i are employed in `connection with the manufacture of boots and shoes.

The object of the inventionis to provide and I have shown how it `maybe utilized in connection `with a tree so that it maybe employed practically throughout the proc-` ess of nianut'acturinga shoe.

Figure l illustrates a `tree foot with my last thereto attached. F ig.` 2 represents a similar view, and shows the last shortened :trom end to end by moving one of the parts thereof transversely with reference to the other. Fig. 3 represents a sectionon line 3MB oi Fig.` 1. Fig. 4l. represents a longitudinal f.section through the last, and also :illustrates the tree leg member which movesl the locking device in position to free the` two parts of the last. Fig. 5 is a similar section through the last, and shows the `forepart` and heel part in position to permit the Lentrance of the last into a shoe or its withdrawal therefrom. Fig. 6 represents an eni larged section on the line 6 6 oi' F ig.` 5;

Fig. 7 illustrates the lower endoi' the tree leg in Section. i i I The last is illustratedas being made ot a. single block which is sawed oi' divided `by a `tiansverse cut into two sections indicated at a and b. rlheiplane `oi intersection be-1 tween the two partsiis inclined or oblique from the top of the` last rearwardly toward t the heel end, so that, when one of the parts or sections is moved `transversely relatively to the other part, the last, as a whole, will be shortened from end to end so that it may be easily inserted into `or removed from a` Shoe.

torepartb and the heel part a of the last are formed with alined slots or grooves indicated at a b, which extend from the top to'the bottom of said parts; and placed in said grooves is a connection `consisting of a web or flat plate 0 which has a sliding lit therein without anyappreciable lost lateral motion. This plate is formed or provided with four slots longitudinally of its length,

these slots being indicated at o, c2, c and o4@ lhe slots are all parallel `to the confronting or abutting faces of the forepart and` heel part, and the slots c and o" maybe in alinement with those at c? c respectively, as shown in the drawings, though this isnot essential.

`Passed transversely through the forepart aretwo pins or fasteners l d which extend through the` slots c c2, there being passed through the heel part two similar pins ori` fastenings` Z2 (Z3, which` pass through the slots c3 o. These pins orifasteneis are so located that, whenthe heel part and forepart are in theiri normal positions, `as

shownin Fig. 1i, the pins Z d will be seated against the upper ends ofthe slots c and c2,

and the pins cl2 d will be seated against the lower end walls of the slots 0920*. By reason of this construction, it willbe apparent that there is possible a relative movement betweenthe plate ci. and the forepart b, and between the plate c land the heel part a, in

consequence of which, there is a relative` movement of the heel part and forepart to a distance substantially twice the length of the slots c and o3 or ci" and cfless the thickness ot' two ot thepieces, as shown in Fig.`

11. 'lhenpins ,d, cl2, lavare in sliding enf.` gagement with the web orplate and theyl constitute means projecting laterally ,t1-omg i the said web `or plate for preventing the longitudinal separation oi' the forepart and heel part. i

I provide` for locking each of the two parts a and b to the plate c, and to this end I employ a lock `which `is indicated at e.;` This consists fot an elongated metallic plate.`

which is located in a groove or recess c in one `tace of the plate c. The lock e is fulcriinied upona pivot f, passed into the plate c, and it is formed or provided with two shoulders e` @2 on opposite sides of the pivot which may be engagedwith thepins ori` fasteners dds respectively, as shown in` Fig.;

4f. The lock isheld yieldingly in this position by a spring g, and it may be moved into the position shown in Fig. so as to release the plate from the pins and permit a relative movement of the two parts a andv b and the plate c. When the forepart and heel part are brought into alineinent or into their normal positions, the lock is moved automatically by the spring into its active position, where its faces or shoulders e e2 engage the pins cl3 and al, so that the forepart is locked rigidly against transverse movement relatively to the heel part, the plate being locked relatively to each of said parts. The provision of the four pins in connection with the plate, makes a strong, stillA last that is not liable to get broken; and by permitting relative movement of the plate, the forepart and the heel part, a greater amount of movement of one of the said parts relatively to the other' is secured than if the plate were rigidly secured to one of said parts. The lower end of the plate conforms to the curvature of the bottom or shank of the last, but a portion of its upper end projects beyond the last, the latter being cut away, as at 7i, to eXpose a pin orprojection e3 on the lock. The pin or projection c3 permits one to engage the lock and move it into inactive position, as shown in Fig. 5.

rlhe top of the heel part is illustrated as flat and as being covered with a plate 'i which may be of leather or other suitable material, leather being preferably used when the last is to be employed in connection with a tree leg. In the vheel part is formed the usual spindle socket jfor receiv ing a spindle on the tree leg.

I have illustrated a convenient form of tree leg with which the last may be employed. As shown in Figs. l, 2 and. 3, the leg is formed of two sections 7c which are secured together in any convenient way. Between them is a hollow chamber k2, see Fig. 7, in which is located a lock-operating device m. This device consists of a flat curved metallic slide having slots fm', through which pass pins m2 which hold it in place, and which guide its movement. The lower end of the slide has an inclined edge m3 which may engagethe projection e3 on the lock and swing the lock about its pivot when the said lock-operating device is forced downwardly. The first downward movement of the 'slide unlocks the portions of the last, and during its continued downward movement, the end of the said slide engages the forepart of the last and forces it to the position shown in dotted lines in Fig. 1.

The slide m is operated by a lever a, the lower end of which is partially circular and which is seated in a complemental socket m4 in said strip. The upper end of the `lever a has a handle a2 by which it may `be manipulated. It likewise has an elongated slot n3 through which passes a pin a inserted transversely into the tree leg k.

I do not wish to be'understood that the lever n and slide m are the only devices which may be utilized to unlock the sections of the last and to move the forepart to an inactive position since any other equivalent mechanism could be utilized for the same purpose. The mechanism which I have illustrated, however, is simple and serves the purpose.

The treeleg is provided with a cylindrif cal spindle 0 which enters the spindle socket in the heel part of thelast. For the purpose of locking the heel part to the spindle, I utilize a rod p, the lower' end of which is wedge-shaped-as at p, so that, when the rod is drawn longitudinally of the leg by any usual or convenient means, the wedge will slide along the inclined face o of the spindle and bind the heel part to the spindle.

Having thus explained the nature of my said invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made or all of the modes of its use, I declare that what I claim is l. A two-part divided last Vcomprising two sections. having obliquely inclined'confronting faces, one of said sections being movable with respect to the other in a plane parallel to said faces, and a connecting plate slidingly connected to each of said sections to move relatively thereto in lines substantially parallel to the face thereof.
