BLOCK-LAST.
To @ZZ whom it may concern:
Be it known that I, EDWIN L. GOD-ING, a citizen of the United States, residing at Sanford, county of York, State of Maine, have invented an Improvement in Block- Lasts, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
My invention is an improvement in block lasts. Aside from a multitude of different spring devices and .other attachments for fastening blocks into place, commonly called block fasteners, there has been very little invention in block lasts, but they have remained substantially the same for many years.
There are at present two principal forms of blocks or block lasts, one in which the block is sawed out with a blunt and somewhat pointed end, being so vmade for the purpose of preventing downward and lateral 0r sidewi'se movement, and the other form in which the block is sawed out to a thin edge, or scoop shape, as itis termed, in which there is, commonly, a groove and dowel construction for preventing` downward and. sidewise movement. Both of these, however, require a block fastener of some kind, and when the common spring devices are not employed, it is usual to simply drive in a tack every time the block is put in place.
The main objections to the foregoingare that the repeated taoking rapidly defaces and spoils the last, the last fasteners are eX- pensive, the scoop shape, or thin-edged, block l requires the objectionable dowel, and is difficult vto put :in place because the dowels are in the way, said dowels are constantly getting loose and .coming out, the blunt ended or V-block often wrinkles and damages the linings when forced into position, and, on the other hand, such last-s when withdrawn (after the removal of the block) catch into thelinings and tongues in lace shoes at the corners and edges adjacent the cavity provided for the blunt end of the block;
Accordingly I have invented anew form of block which obviates all the above objections, my block having a shoulder or ,locke Ing -surface eop'erating with the body of the last in holdingpgit a ainst 4movement in anliireetion when mvp" ace vin the shoe.-

Application filed June 6, 1902.

Serial No. 110,406.
vantages of my invention will be ointed out in the course of the following escription, reference being had to the accompanying drawings, in which I have illustrated certain preferred forms of my invention.
In the drawings, Figure l shows in central longitudinal vertical section a last provided with my invention; Fig. 2 is a perspective view of the block thereof; Fig. 3 is a similar sectional view of another form of the invention; Figs. 4 and 5 are similar sectional views showing still Other embodiments of the invention.
It will be understood that the general construction of the last, aside from the block feature only, may be varied without reference to my invention.
Referring now more particularly to Fig. l, it will be seen that I have rovided a block o having a scoop end whlch is very desirable for many purposes., but instead of having tacks, dowels', etc., I have simply formed an enlargement or projection o on the underside of the upper end of the last block, said enlargement terminating in a downwardly extending shoulder 58 at its lower end which abiits against a corre spending cavity in the last for preventing improper downward and other movement, said shoulder b3 forming an acute angle with that part of the longitudinal line of separation between thelbloc'k and body e'X- tending vfrom .the shoulder tow-ard the toe of the last, and .at the upper end 'of the enlargement I have provided a shoulder or angular cut o?, so that when the last is in .a shoe, in which position, it will be understood, the upper of the shoe holds the last block firmly in place .a aiist the body of the last, there is no .lial ilifty of the block movin in any direction, as considerable force 1s required to pull the block out of the shoe, on account of the obstructive shape at b4. In addition to this, I' secure the cord c ina special manner, boring the hole 'at the line of cut b4 so that apart of the hole forms a notch 6 5 on the block, the rest of the hole being in the body of the last, ,as clearly shown in Figs. l and 2. The oord occupies this notch and aids in preventing sidewise movement of the last block.
Referrincr .now to Fig. .3, where I 1have shown a bock b tennineting at its 'lower end b" .a .blunt end or V'S tyle, itwll be seen that ins'tf'a'ld of providing the 'parhave ticular retaining shape shown in Fig. 1 I rovided a shorter projection bs, having simply the angular or wedge-shaped cut 64 at its rear side, and instead of the curved shoulder b3 shown in Fig. 1 have simply provided a sharp offset b9. This construction is suiiicient for many purposes, and articularly so in connection with the y}le of block, inasmuch as the lower end is prevented from lateral shifting by the blunt point, whereas, in the scoop block shown in F iff. 1 there is nothing at the lower extremity o the block to revent late ral shifting, and hence it is pre erable to bring the end b3 down lower into the last than is required in the forni of construction shown in Fig. 3. The shoulder b* may be' quite high on the last to controlv the position of the upper end, while shoulder b3 may beat the shank or waist region of the last. By having the projection ZJ long and deep as shown it serves to maintain the thin front edge of the block in osition so as to be not liable to contact with the complemental shoulder on the last body. It will be noted also that the block is severed from the last body by a single cut laterally continuous and uninterrupted, as distinguished from an irregular line of cleavage, e. g., where there is present a dovetail connection between block and last.
VIn the construction shown in Fig. 1 it will be noted that the lower surface b1 of the enlargement Z9 is approximately parallel to the crown' of the block, thereby pen mitting the last to move properly in 'and out of the shoe when being inserted or removed therefrom.
In Fig. 4 I have shown a form of my invention which is particularly adapted to small lasts and certain other places, said form consisting simply in providing a retaining surface in the form of a groove 512 in one part and a pin or rounded surface b in the other part; this pin may be a dowel glued into the last, or it may be formed directly thereon.
In Fig. 5 I have shown still another form of retention, consisting of a rotuberance or bunch 6 provided on the b ook and fitting into a corresponding cavity in the body of the last.
From the foregoing it will be readily understood that my invention when considered in its broader aspect resides in rovidin the contacting surfaces of the b ook and ast with interlocking portions so shaped that they offer sufficient resistance to improper movement for the purpose desired.
For McKay work it is now common to use both the scoop block and the' V-style, while the latter only' is applicable to turn shoes or turn work, whereas, by this invention, as will be readily apparent to those skilled in the art, the scoo block may be used for both kinds of wor The forcing in of the scoop block the second time no longer will tend to ruin the edge of the block or loosen the fastening pin, because by my invention no fastenin pin or obstruction is present. By having the ledge or interlocking shoulders of considerab e depth and extending across the block, as shown, all tendency to twist or shift at one end or the other outof position is prevented. It is not necessary, under ordinary circumstances, that the last block should be absolutely locked positively against movement, inasmuch as the strain of the leather causes the secant surfaces of the block and last to hug tightly together with sufficient firmness to maintain the block in proper position under all ordinary circumstances simply by providing a wedging surface or irregularity on one part cooperating with an oppositely formed surface on the other part.
I prefer the constructions shown in the drawings, particularly that shown in Fig. 1, but do not intend to limit myself thereto inasmuch as many modifications and changes may be resorted toin view of the foregoing description without departing from the spirit and scope of my invention.
Having described my invention, what I claim as new and desire to secure by Letters Patent of the'Uiiited States, is
1. A last, comprising complementary shaped instep block and body, the-block having upon its body engaging surface an outwardly projecting portion extending transversely from side to side of the block and arranged to resist upward movement of the block on the body longitudinally of the last.
2. A last comprising complementary shaped block and body, said block and body having formed integrally therewith interlocking portions intermediate the ends of the block arranged to resist upward movement of they block upon the body.
3. A last comprising complementary shaped instep block and body, the block having formed integrally therewith an outwardly extending projection on its body engag'ing surface arranged to resist -upward movement of the block upon the body.
4. A last comprising complementary shaped block and body, the block having formed integrally therewith an outwardly projecting portion on its body engaging sur face constructed to resist upward movement of the block upon the body, said portion being provided with a forwardly extending shoulder at its lower eXtremit arranged to resist downward movement o the block on the body. f
5. A block last, comprising complementary shaped block and body, the u per portion of the contacting surfaces o the two members immediately below the upper'end of the block being deflected to form an obstruction to the removal of the block.
6. A block last comprising complementary shaped block and body, and a cord lyin between and extending into engaging portions of block and body at the extreme upper part of block and bodyto prevent relative lateral movement of block and body.
7. A block last comprising a block and a body, secured together by a cord, one end of which is secured in the block and the other end secured in the body at the surface of contact of block and body, and projecting into the block to prevent lateral shifting movement thereof, the portion of the cord intermediate said ends being arranged exteriorly to the last.
S. A last comprising complementary shaped block and body, the block having formed integrally therewith an outwardly projecting portion on its body engaging surface, constructed to resist upward movement of the block upon the body, said portion being provided with aforwardly eX- tending shoulder at its lower extremity, said shoulder at its side neXt the instep forming an acute angle with the longitudinal line of separation between block and body extend- 4ing from the shoulder toward the toe of the last.
9. A block last having the secant surfaces between the block and last formed with an offset or resistance surface for preventing rearward or outward movement of the block when in place ina shoe, said block and last being secured together' by a oord, one end of which is secured in the block and the other end is secured in the last body at the meeting top edges of the last and last block and projecting into the latter for preventing lateral shifting movement thereof.
l0. A last, comprising complementary shaped block and body, said block and'body having formed upon their contacting snrfaces intermediate the ends of the block interlocking portions arranged to resist upward movement of the block upon the body.
In testimony whereof, I have signed my name to this speciication, in the presence of two subscribing witnesses.
