TQ all whom 'it may concern.'

Be 1t known 'that I, GEORGE CLAUSING, a

i citizen of the United States,l residing in the' city of Portsmouth, in 'the-"county of Scioto and State of Ohio, bave-invented certain new and useful Improvements in Lasts, (Case H,) of whiehthe following is a specific-ation.

The object of the invention is to produce a simple, strong, practical" and rigid last which can be readily broken or fiexed so as to faciiitate the' removal of the last'rom the shoe and so that the Ashoe will not be marred, broken or ulledout of shape during the` removal of t e last from the shoe.

.l According. tothe presentv invention a last is constructed Aso that it will comprise a forward or toe part and a rear or heel vpart which are provided between them with main hearing pins or members that extend transversely to the last.v The heel and toe parts Y are connected together by a longitudinally extending rod or link, one end` of which rod is' pivotally conneetedto the toe part and the other end of which is pivotally connected to the heel part. When this link occupies its lower position the heel and toe parts voccupy their unbroken position relative to'eacb other. This link is normally presseddownwardly by a compression springr which is located in the toe. part above said li'nk.

As showimgr a specific embodiment ot the invention reference is made to the drawing forming a part of this specification and in which,-

Figure 1 is a vertically and longitudinally extending sectional view of the last. In this figure the full lines indicate the position of the parts when in extended or unbroken position, While the broken lines indicate the position of the heel part relative to the toe pair't l,when the last is broken or fiexed. Fig.

QNis a' pian view, partially in section. This figure-fis aview taken on the line 2f-2 of Fig. l., looking in thedirection of the. arrows. Fig. 3 is a transverse sectional view taken on the line 3--3 of Fig. l lookingI in the direction of the arrows. Fig. 4 is a seetional view ot' the toe part showing` the manner in which 'the iink rei-airing' opening may be formed. l

The last A comprises the forward or toe part B and the rear or heel part C. In the construction of the ias't the toe and heel Specification ofLetters Patent. i Patented Aug'. 18, 1914;, Application filed February 12, 1914. Serial No. 818,353.

by transversely sawing as along t-he ine dd and a V shaped portion d, e and f is sawed out and removed from the last whereby the heel part can move from the position indicated by the full lines in Fig. 1 to the position indicated by the dotted lines in order to break, flex or shorten the last. vAt the juncture of the saw cuts indicated by the line r-d on one hand and by the line e-f on the other, there is located the main bearing members or pivot pins F-F. .These pins are preferably seeiired as by the pins or nails f-f to the toe part of the last. It will be manifest however that in s ome constructions these main bearing members instead of beingr independent from may he formed integral with and of the same material as the toe art, for instance, since all that is necessary 1n the last construction is to have circular hearing surfaceon one of the partsA which can fit into the curved recess portions on the other part- Afterthe heel and toe parts have been separated by transversely sawing 'along the4 li ne (I-d, they are each provided with openj ings for receiving the connecting link or bar (i. These openings may be formed by boring in each part a couple of openings q(/'-g, inclined to each other. 'Thesebored openings run into eaoli other and the materialgns g, between the-m is subsequently removed, thus forn'ng the triangular shaped opening h in the toe part and the opening in the heel part. This connecting link, which is shown of circular cross section, is pivotally connected to the Vtoe part by the pin orrivet 7' and to the heel part h v pin or rivet lc. .One of the openings through which one of the pins or rivets pass is elongated, as at 7),to permit the. heel and toe parts to be moved to full fiexed position when desired. This linkis arrangedA swings to the cdotted position shown in Fig.v

i so that the line passing through said pivot centers is located above the axis of the main hearing pins F when the heel part occupes the position indicated by the broken lines, or namely, when'the heel and toe parts occupy the fullv vflexed or broke-n position. The. toe part is also provided with the ven. ticnlly extending'hored opening Zin which there is located the spring means M thatr comprises the con pression spring' m, and the springr cap n that engnges'thel connectf ing link G at or adjacent to the central por-v tion of the link. Thisspring, as will he JJ observed from the drawing, is located above the. connecting link and normally presses` ngrslinstthe lutter, thus tending to force the mst parts -townrdunbroken.position and also tending to nmmtam said last partsin 15 said unbroken position .when they are in said position. The linli G serves to connect :1nd hold the toe undl heel ports together und asthe control portion-of this link is engaged hy the spring means M, the latter 20 tend to very effectively force the link downwardly and thus securely maintz'iin the heel und toe pin-ts in unbroken position und in tirni engagement with enr-h other.

From the inspection of Fig. 1' it will'lie full length ofthe forward trnnsverselfextendlng face of thc heel pan-t and that-,the mam nearing pins F are shown as being secured tofthc toe pint.' The recess f inw 3o the heel part 1s Senn-circular,thus affording n very substantiel hearingt aren ,between th heel part ltlie :nain 'hearing pins/or mcmhers.- This is quite importantl :is the wem tends to tule: place lietiveen'tlie bear# 35 ing or xneniihei's and the member which moves relative tothe hearing pins or members In other. words, il".` will he seen that the large h ing urea. is'lon thopmt that moves relative to the'henring pins :ind that 4g there is loss are. between the hearing pins und thc. n'nxnli-:ir to'yafliivh they are secured.
