Specification of Letters FatemiA Pa-idhted DCC. 31, 1912- Application filed June 16, 1906. Serial No.` 322,070.

T all icflom it may concern.:

Be it known that I, ORRELL ASHTON, a citizen of ,the United States, residing at Lawrence, inthe' county of AEssex and Commonwealth of Massaclillsetts,\have invented certain Improvements in Pounding-Up Machines, of which the following description,

in connection with the accompanying drawings,is a specification, like reference char actors on the drawings indicating like parts; in the several'figures.v f

This invention relates to machines used in` the manufacture ofboots and shoes and is herein shown asembodied in amachine of the type shown in United States Lett-ers Patent to M cFeely, No. 1,019,067, granted March 5, 1912, intended for performing the operations of poundingiup and of blocking shoes. It is foundin: practice that lasts differ enough. in shape so. that theacting face of a blocking tool can not be so formed that it willact uniformly on diilierent lasts.

One feature of the invention consists in a novel construction .and arrangement by 4which the blocking tool is enabled to adapt itself lreadily to the Contoursof different lasts. To this end there is provided'an improved arrangement for permitting thev blocking tool to be turned by engagement with the work and also' to yield bodily backwardi,v in whatever angular position ithas assumed, after it strikes the work. AFor the purposeof further improving the means for 4 blocking the shoe, the construction and ar` rangement of the biocking -tool and of its supporting aifd opera iff means are such as tocause the tool to snire't'ne shoe lightly and then, after beingdisplaced if necessary,

as by turning, foifconforming to the Contour and position ,of the surface ofthe shoeto betreated, to be forced with. increased pressure.Y

against the side-of theshoe for shaping it. In blocking means thus constructed and arranged the blocking'tool will bet-ter adapt` itself Vto the contour and position .of thev work than will such tools as heretofore' constructed. i I1`iirt-l1`er-*rnbre5t`he blow is not cloni-" centrated on as'srnall a" vportion of thevmrkf as is the Case either Vwith tools rigidly 'mount--VV ed or with tools having lesscapacity'for ad- -essential and, in fact, if the shoe upper consists of certain light grades of leather, the blocking tool is liable to bruise or mar the leather. 'In accordance with another feature of this invention, therefore', means-is provided for rendering thfejblocking tool inoperative wit-hout affecting the operation of ,other mechanisms of the machine. A To this.

blocking tool or whicli'mayexist-when vtheA blocking tool is not used. `When the bl'o'ckV ing tool is used, the smoothing means may" be located adjacent' thereto and preferably will comprise a pair of tools arranged/one upon each side of the`blocking`means, 'although, if desired, theifs'iiibothing means may comprise a singie member positioned and arranged to engag'efthe-"shoe immediately after the operation-fof the blocking means thereon. Theaeting faces of the smoothing tools are prefetblyforined 'so as to insure that as large a portion of the side of the shoe as is practicable shall be smoothed. For the purpose of further extending the surface ofthe work that maybe y treated andvfor enabling these tools to adapt themselves to the slightly-varying 'contours of different portions of the work, the tools are each mounted to yield under pressure of the work-against them'andalso tojbe turned,-

alternatively or successively, 'about axes located at different altitudes. Another feature of the invention consists m means especially adapted for treating the edge portion of tlrefuppei'ratthc junction of .f

the side and bottom-faces ofthe shoe to remove wrinkles and other inequalities which are sometimes formed at the edge of the shoe and .which it is ditlicult to remove by pounding up and blocking tools. To this end the smoothing tools have faces adapted to engage the edge of the shoe and preferably to overhang slightly the bottoni of the shoe and the machine has provision both imparting t .these tools' through-'their sup`A ports a light vibratory 'movement toward and from the work and also forl vibrating or rocking them about pivotal 'connections with their supports. Bythis construction,

the lsmoothing tools .are caused to deliver light ra'f'id blows directedv to the 'edge of the shoe the character of the blows and the above or tlined Yconformation. of the' working faces of the toolsresulting in most efficiently smoothing and shaping lthe edge of the'shoe. This action of the smoothing tools is more gentle than the action of'theblocking, tooland said tools can Atherefore be usedfadvaf tageouslyV on the lighter'kinds of upper leatheras well as upon hea'viersho'es.

Mv ci; `riments have furthermore demonstra-ted t at by" heating the vamp on the side of a shoe inadvance of the operation of a" beating or finishing. tool thereonfthe effectiveness of the succeeding action of such tool is" greatly increased, since the leather ofl the 0r simultaneously with the smoothing orrubbing actionofi the finishing tool, such' treatment of the upper tendingto lay the grain of the leather andl to give a superior appearance to the shoe. In operatin upon some grades of shoes, entirely-l satis actory results' can be obtained thus applying heat to the upper and .treating it by a smoothing or finishing toolA without usingA a beating tool'at all. It isalso partieulaidy advantageous to smooth-and rub 'under heat Athe edge of the upper' formed vby the junction of the side and` bottom faces of vtheshoe and thus entirely toiinish this portion of the' shoe at this pointin the manufacture of the shoe in yView of the -faet `that after the sole is attached to the ,shoe it is exceedingly in -`v convenient to get at this edge portion of 'the upper for polishing or otherwise finishing-V it. Furthermore, 1` n the manu-facture of shoes havingvampsv or tips 'of patentjleather,

' enameled' leather or similar. "stock, here-' in referred to vgenerically-as enameled leather Vfine wrinkles and 'surface inequalities are frequently made .at:the sides and edges of the .shoe because offune'qual stretching of the leatherfbase and its enamel coating where the vampis bent .over the edge ofthe last.`` The enameleamfhcwever,

be softened and shrunk and such Wrinkles Vobliterated by heating the ena-mel 'in advance.

Tie fra'me 2 supports a fulcrum pin 92' ioo,

for a lever 90 which 'has connection through a'lin'k 86v and intermediate devices, for-ming -nofpart .of the present invention, -with a crank 70'on"the driving shaft4 by means of which thelever is oscillated. The lever 90 i's forked at its upper end'and provided with adjustablev caps '95 containing springs97 acting on plungers 99 between which islocaieda-laterally projecting Yportion or flange d of acarrier lever 100. -The pounding-up means-the sp'eciiicconstructionof which is not -a part of the present invention, is here 'in shown as'comprising a head 106 mounted 'Y on ashank" 108 which is Vlongitudinallymovable in a guideway in thev carrier levervand arranged to beoscillated with said-carrier! lever toward and from the work andto be- 'reciprocated .relatively--intheguideway.

The particular construction of the poundingv up means isnot important to the 'present inf vention. and any other suitable pounding-up vmeans maybe substitutedfor the one shown inthe present embodiment of the invention.

The blocking means, which-as herein-shown;

` scends.

is carried by the lever 100, comprises a shank 148 which is longitudinally movable in a guideway 10i in the lever. The blocking means is moved toward and from the plane of the shoe bottom by the oscillation of the carrier lever and is actuated longitudinally in its guideway for striking the work by .reason of its inertia which causes it to move backwardly when the carrier lever rises and to be impelled forwardly when the lever de- The forward movement is accelerated by a spring 154 which-is compressed during the rearward movements of blocking means and expands during its for ward movement. 'lhe blocking means comprises further a head 141 having an acting face shaped to conform approximately to the side of the fore part of an inverted shoe from the edge e downwardly. The head is connected to the shank 11S by a pin and slot connection 1-13, shown in full and dotted lines in Fig. Q. This connection permits the head of the blocking tool to havea slight rocking movei'nent either upwardly or downwardly from its normal central position. A'spring-pressed plunger 145 is here in shown as mounted in the shank directly in the rear of the pin and slot connection and in position to hold the head 141 normally in its central position. The pinV and slot con nection also permits the blocking tool to have va rearward bodily movement with ree lation to its shank, this movement being limited by the engagement of the rear face of the tool with a collar 147 on the shank. The spring 149 acting upon the plunger 145 and normally holding the blocking tool at the limit of its forward movement away from the collar 147 is much lighter than the spring 154, which assists in impelling the blocking tool forwardly. By this construction and arrangement the blocking tool is permitted when it strikes the Work to rock upon its pivot and adjust itself to the posi tion and contour of the portion of the side of the shoe engaged by it. During this rocking movement the shank of the tool will continuey its forward movement until the lost motion permitted by the. pin and slot .connection is exhausted. whereupon the blocking tool. which has become properly adjusted. will be actuated againsbthe work with the full force of the spring 154 and the momentum which it has acquired during the downstroke of the carrier lever.

Provision is made for renderingtheblock` ing tool inoperative at times. '.l`o this end means is provided for limiting or discontinuing the reciprocation of the blocking tool and for holding it in a retracted position where it will not engage the work when the carrier lever is oscillated. In Figs. 2 and i?. the carrier lever is shown as provided with a locking pin 151 which is normally held by a'spring 153 in the position illustrated, said latcd as described.

the

pin having a reduced portion 155 located adjacenty to the shank 11S ot' the blocking tool. The pin 111 has' a head 15T by means of which it may be moved in opposition to the tension of thc ,spring 152') to bring a thick portion ot' the pin into position to toiipcrate with a shoulder 155| on thc shank for hohling the blocking tool in a retracted position. The blocking tool requires to be pressed backwardly against the tension ofthe spring 1` t before the locking pin can be maniptn 'l`he locking pin has a .stud 1111 for engaging a shoulder 111% on the lever to hold the pin`in its adjusted position. ln Figs. 5 and .3 is illustrated a moditied construction b v means of which the movement of the blocking tool into its rctracted pcsition and the locking of the tool may be con\enientl v effected. This construction comprises a. collar 165 mounted on the rear portion of the shank 118 and provided with a forwartilly extending member herein shown as a half sleeve. A second collar 16T abuts against the rear end ot the carrier 'lever 100 and has a irarwardly e.\'- tending projection, also shown as a half sleeve. The blocking tool may be retracted by engaging the collar 165 and pulling it to the rear and the tool may be locked in this retracted position by rotating the collar 167 to bring its half sleeve into alinenient with the half sleeve on the collar 1(15, as shown in Fig. fhe free end faces of the half sleeves are shown as roughened to prevent accidental rotary movement when these faces are in engagement. It is obvious that it is not important to form the cooperating projectionscarried b v the vcollars 1.65 and 167 as half sleeves for any suitable construction of projection and cooperating recessed member would serve the same purpose.

For smoothing the upper material the machine is provided with one or more tools 171.' These tools artA preferably alike and areeach formed with surfaces shaped to act. upon the side ot' the shoe adjacent to the bottom-of the shoe. As herein shown, the lower portions of the tools have receding faces 173 to enable them to act upon the side of the shoe at the shank-for example. as shown in Fig. Mthe curved surfaces of these faces avoidine' all danger of the upper being marred by t e tools. Preferably the smoothing tools are provided with faces 175 shaped to conform approximately to the corner or edge c of the shoe formed by the junction of the side and bottom faces. As shown. the faces 175 are extended to overhang slightly the bottom ot the shoe. The machine herein illustrated is provided with a smoothing tool located upon either side of the plane in which thc pounding-up and blocking tools are mounted7 but if desired a single smoothing tool may be employed which will preferably be.mounted on the rear side of the pounding-up and blocking tools or, 1n position to operate on successive portions of the shoe after they have been `acted upon by the pounding-up and blocking tools. In using the machine the shoe is firmly pressed laterally against the smoothing tool or tools and as it is fed forward the tools rub the side and preferably the edge of the shoe to smooth it and remove any wrinkles or marks which may exist. Preferably the shoe will be supported upon a jack Q00 and a spring 218 may be employed as shown in Fig. 1 to assist the operator in actuating the jack and shoe toward the smoothing tools. Preferably the smoothing tools 171 will be yieldingly supported and as shown in Fig. 7 the tools are so mounted upon their supports 177 that they may be pressed backwardly against the tension of spring-pressed plungers 179. As herein shown the smoothing tools are also connected to their supports 177 for' pivotal movement about two centers located one above the other, as in Fig. 7. This Connection is formed by the pins 181, shown as carried by the support 177. and by curved slots formed in the rear 'ardly extending Shanks 185 of the tools7 as clearly shown in Fig. 7L This arrangement permits the tools to adapt their position to the position and contour of the portion of-the shoe pressedl against them.

The supports 177, upon which the smoothing tools are mounted. are preferably con nected rigidly to the frame Q of the machine upon which the carrier lever 109 is pivoted. In practice the carrier lever is rapidly os'- cillated and causes a vibration of the m1- chine frame forwardly and baelm'ardly. lu accordance with one feature of this invention this vibration of the machine frame effected by the rapid oscillation of the carrier lever and its actuating mechanism is utilized for vibrating the smoothing tools to cause them to deliver light rapid blows upon the side and edge of the shoe. The point of the engagement of the shoe with the smoothing` tools is above the lower pivot pins 181 and the vibration of the frame causes the smoothing tools to rock or vibrate slightly about said pivot pins 181. as centers in addition to their movement forwardly and backwardly with the vibrating frame. This rocking movement of the tools about the pivot pins causes the faces 175 of the tools and the adjacent portions of the tools overhanging the shoe bottom to strike lbe edge of the shoe with oblique blows inclined downwardly and outwardly with relation to the machine o` downwardly and inwardly with relati o; to the shoe bottom. as will be readily understood from Fig. 7. For the purpose of rendering the smoothing i.: :is more effective for beating the side and cage of the shoe the tools are. extended upwardly and enlarged as shown at 187 to increase their weight.

Preferably provision will be made for heating the smoothing tool or tools to enable said tools to be employed for ironing portions of the shoe engaged by them when the machine is employed for operating upon chrome-tanned and other grades .of upper leather that can be advantageously treated with a heated iron. This is of great ad'- vantage because the edge of the lasted shoe acted upon by the smoothing tools and the portion of the side of the shoe adjacent to the edge is not easiluv accessible to an ironing tool after the sole has been applied to the shoe7 whereas in accordance with this feature of the present invention the edge and side of the shoe can be conveniently ironed before the sole is applied to the shoe and when these parts of the shoe are fre ly accessible.

Any suitable means may be employed for heating the ironing tools. ln the main tig'- ures of the drawings is shown means for heating the tools by steam. This means comprises a steam box 191 supported upon a convenient portion of the frame and furnished with steam from suitable inlet and outlet supply pipes 193. Preferably the steam box will be provided with means for engaging the smoothing tools so that heat may be conducted directly to the tools. As herein shown the steam box is provided with a plate 195 pivotally secured to the steam box by a pin and slot connection and pressed yieldingly against the lower ptrtions of the smoothing irons `by a spring 197, see Figs. 2 and 11. This construction insures that the plate 195 shall be maintained in contact with both of the smoothing irons in the different positions which said irons assume in their movements. In

Fig. 10 a gas pipe 19S is' shown as support.

ed in position to heat the smoothing tools while in Fig. 12 a box 199 suitable for containing and burning alcohol or oil is shown with burners in position to heat the smoothing tools. The machine is shown provided with two tools 171 and with means for heating both cf these tools. The toot which acts upon tht stock in advance of the action of the pounding-up and blocking tools heats and softens the stock so that it responds more reat'fity to the action of the blocking tool. in rcn'foving wrinkles or inequalities from theftock and iushaping the side of the shoe. rlie tool which acts on the ,stock after the pounding and blocking tools smooths and irons it in a manner simi,- lar to that in which the other portions of the shoe upper are usually ironed.- in the operation of finishing the slice it is of course -not necfssary to empire.' two soothing or ential that The heattools and it is not l ironing if employed be heat ing means serves to heat to some extent the blocking and ironing tools and this enables those tools to perform their functions more etfectively.

ln the use of the machine the shoe, preferably supported upon the jack 200, is lield by thc operator, assisted by the spring 218 if the spring is employed, against the smoothing tools in position to be acted upon by the pounding-up and blocking tools. then the machine is started the carrie-r le ver 100 is oscillated about its pivot 92 moving the pounding-up toolwith it toward and from the work, and in practice the tool reciprocates in its guideway in the carrier lever sothat it forces the upper material on the shoe bottom downwardly toward the innersole and inwardly away from the edge of the innersole. The blocking tool is moved by the carrier lever toward and froln the plane of the shoe and is caused by the oscillation `of the lever to reciprocate in its guideway and to strike the shoe after the poul ding-up tool has engaged the shoe bot.- tom and therefore position the blocking tool vertically by arresting the downward movement of the carrier lever. As the blocking tool is impelled forwardly in 'its guideway into engagement with the side of the shoe the light spring 149 is compressed until the rear face of the tool comes into contact with thc collar 147 on the shank of the tool. During the compression' of this spring the tool may rock about its pivot 143 to adapt its position to the contour and position of the shoe. "hen the collar 147 on the shank engages the rear face of the tool the tool will be actuated forwardly against the shoe with the full force produced by its momentum andthe expansion of spring 154. If the operation of the blocking tool is not desired the tool can be rendered inoperative by forcing it into a retracted position in its guideway and securing it byv the locking pin 151, or it may be retract-ed by moving the device 165 to the rear and may be locked by turning Said device to bring its half sleeve or projection into engagement with the opter face of the half sleeve or projection of the device 167. In presenting the shoe in position to be operated upon by the pounding-up tool and the blocking tool the shoe may be pressed against the smoothing to-ols with suiicient force to rub out and smooth wrinkles or uneven places in the portion of the shoe engaged by the smoothingtools The faces 175 of these tools will act upon the edgenof the shoe for smoothing and evening it and preferably the smoothing tools will vibrate with the machine and rock about the pivotal connections with their supports for beating the side and ed'ge of the shoe. 1f the smoothing tools are heated they will also iron the portions of the side and edgeof the shoe engaged by them. Vhile good results can be obtained by using one 'smoothing tool located in position to act on the stock after it has been acted upon by the pounding-up and blocking devices, preferably two tools will be used and when they' are heated the tool wli ich 1c ts uponthe stock` in advance of the action of the blocking and poundingup tools will heat and. soften the stock, thus prt aring it for the action of the blocking tool? while the tool which is located in pos1- tion to act on the stock after it has been acted upon by the pounding-up and blocking tools will iron the upper, removing any wrinkles which may remain and also any marks which may not have been obliterated or may have been made by the blocking tool. The latter smoothing tool thus acts to iron and finish the portion of upper at and adjacent to ythe edge of the shoe which is not conveniently accessible for inishin T after the sole of the shoe-has been attache "'hen operating on some kinds of shoes the use of the blocking tool may be dispensed with and the smoothing and ironing tools alone depended upon for shaping-and tinishing the side and edge-ofthe shoe.

lhen shoes having 'Vamps og tips of enameled leather are beingoperated upon the use of one or mor-e heated tools, as 171, serves to soften the enameled leather to prepare it for the action of the blocking tool if that tool is used, and to make more effective the rubbing action of the smoothing tools. In addition to this the heat seems to shrink the enamel the result being that the wrinkles are obliterated. This removal of the wrinkles is probably facilitated by the rubbingI contact of the tool 171 against the shoe, but this invention is of course not limited to a construction in which the heating means contacts with the work.
