l To all whom it may concern' Be it known that l, Wennen, P. Boe- Wonrrr, e citizen of the United States, ond :i resident of' Brockton, in the county Gif Plymouth and State ci Massachusetts, lieve invented certeinnevv ond useful improve'- for Melting. Heelloge, oi' which the following is e'epeciticatio-n.

This invention relates to e machine of the type shown by Letters Potent oli the United States llo.` 936,858, .dated @ctobcr 12, 1909, comprising' o rigid vertical heelshaped mold which is open et both ende, Ineens for pressing cement or pastecozited heel lifts-into and through said moldi the lifts being laterally contracted end pressed together While passing through the mold and thus forming' o, vertical assemblage of lifts known ne n heel log, ond on elonggted length below guide receiving the heel log ne it emerges troni the mold, and directingr the log in ite downward cmireeu the cement or poete loedried While the log; ie pnssi'ng through the guide so that the lower end of the log which emergen from the guide ie rncticnllyprigid and ie adopted to he converted into heel logs of any desired'thiclr neen, preferably loy cutting ed the port of the log which protrnde's from the lower end of the guide and enb-dividingjthe cntbfli portioirintoheel bodice of@ blanks by n snit or slicing machine. ln the mocornposed of here which are spaced eport to expose porn ltiene of the log and permit the seine to dry quickly, the lower end ot the log being supported by a 'sliding platform or rest which is movable within the guide and is yieldingly supported by Weighted cords, the ob- AAfect of said rest being' to prevent, the lower portion of the logF from being lorolren off 'from the upper portion by itey ovm Weight. When e. loe," ermeeding;` the combined length' of theinold end guide has been formed, the

reet projects 'with the lower end of the log below the guide :ind has to be temporarily displaced While the 1protrudingu portion oi the log ie heine detached, `the reet beine subsequently returned to the position to support the lower end ci" the log.

The preeent invention has tor ite -o'oiect eernblage of lifts to dispense with the scid sliding; rest or platform end to enable the guide here to yieldingly support the log and prevent the breakage of the log;r bv its own Weight, the lower end of the guide lloeing continuously unobstructed to permit the lower end of the lon' to emerge therefrom ond he cnt off with ont the inconvenience involved in displacing the rest oi.E the said prior potent and returnI inn" it to place.

|llhe invention consiete in the improvements which l will now proceed to describe and claim.

0i' the accompanying drawings forming n port oi. this soeciiientioin-Fizure l repre sente n. side elevation of :i portion oit' n heellogbuilding machine embodying; my invention.' Fig. Z reprcoents n longitudinal siection on the line 2f-2 of Fig; l. Figi'. 3 represente :rtrnnsve'rse section on the lino fl-3 oli l. Fin'. i represents n transverse sec tion lon the line iwiof Fig. l.

lin the drawings,-o represents n rigid vert-ical mold which' is open nt both ends and is adopted to receive und laterally contrect onosseinbloge of heel lifts o which hove heen coated 4with poste ond inserted in the upper end of the. mold, each litt being either composed of o. single piece or, ne shown by Figs. 3 and l, of e plurality of sections forming n pieecd lift. The mold is rigidly Secured to o. casing or holder c forming n port oi the .trame of the inechiney said holder being; lor the purposes of this inven tion considered ne o part of the mold.

CZ represente n. verticali* eleel'inned pino:V ,fier which is adopted to he vertically ro; ciirocated und to enter the upper end of the mold and press downwardly therein o litt or lensembleige of lifts b, the li'lts being*- placed in the upper end of the mold by' nn attendent While the plunger is raised. The plunger, which may be operated by mechenisrn shown inl the above-mentioned potent or any other suitable mechanism, forcee the lifts downwardly step-by-etep through the or opening enlrciently resieting the down* Word, movement of the freshly coatedlifte to importthe desired form to their margins 'and conse close Contact` between their opposed surfaces, so that :in ne extendin from the Yof the mold upper portion to the lower en constitutes a heel log which is caused to .emerge from the lower end of the mold by `tice, thi` length otl the rigid mold is necessarily, limited to a tew inches to obviate the necessity` or undue resistance to the downward movement of the log by the plunger d.

In carrying out. my invention, I provide below the mold o a series of preferably four elongated vertical guide bars 12 which are loosely supported and are movable laterally to a limited extent independently of each other, and meansllor pressing said guide bars yieldingly against the surface of the portion ol the heel lop; which projects below the mold. The guide Lars 12 are formed to bear on portions of the perimeter of the heel log', as'shown by Figs. 3 and el, and each bar is preferably made ofmctal of angular form in cross section, two of the bars 'being preferably provided with cheek pieces 13 which may he of wood and have their inner surfaces curved to conform to portions of the curved sui-tace ot the heel log. The guide bars are preferably suspended from the lower portion of the mold by means of suspension rods 1-1 pivoted at their upper ends to the mold or the casing c thereof, and at their lower ends to the guide bars at points below the mold, as shown by Figs. 1 and 2, which show studs 15 attached to the mold casing` c and engaged wit. eyes at the upper ends of the rods 14, and studs 1G attached to the guide bars and engaged with eyes at the lower ends of the rods. The guide bars are thus adapted to move laterally to a limiti-,l extent inuependently of each other and at the same time are securely supported against dowuwa rd displacement. The lower end ol themold and the upper ends of the guide bars are Y members adapted to prevent lateralniovement ot the upper ends of the bars, these members including an extension 17 of the mold tilting within extensions 18 ot'Y the 4guide bars. so that the proper passage of the loe; from the mold into the space between the guide bars is insured.

For pressinrr the guide bars against the heel log, I prefer to employ contractile springs 19 attached at their ends to studs 20 on adjacent guide bars, said springs being preferably arranged in sets each including four springs as shown by Fig. 3. The sets l of springs are suitably spaced apart, the distance between each set of springs and the next and the number of sets employed del provided with interlockingl 'gaged with said sockets. each bar being provided with a steady pin Q3 engaging a socket 22 on 'the next bar, and the steady pins and sockets forming a set or series surrounding the guide bars, as shown by Fig. 4. The sets of sockets and steady pins preferably' alterl nate wi-th the sets of springs 19, as shown by i Fig. 1. These devices tend to keep the bars in parallelism with each other.

The length of the'g'uide bars is preferably from thirty to sixty feet so they are adapted to control a log of. corresponding` lengt-h,

time for the paste to dry and harden between the lower end .of the mold and thel lower end of theguide formed by the guide bars. Said structed so that the protruding dry anti hardened end of the heel log may baconveniently removed as required." 'f
