To all whomfitmey concern: i Be it known that I, WARREN FRASIER, a citizen `of the AUnited States, residing at ,.Lynn, in thecounty of Essex and State of Massachusetts, have invented `certain new and useful Improvements in Sole-Pressing Machines, and do hereby declare the following to be la full, clear, and eXact description of the invention, such asl will lenable others skilled in the art to which it appertains to make and use the same.

` The present invention relates to sole press- V ing machines and more particularlyto that clas'slof sole'pressingmachines which comprise a shoe 'supporting jack, and a -form` coperatingtherewith to Subjectthe sole of a shoe supported upon'the jack to a rolling pressure. v y

In rolling pressure 'sole pressing machines,

difficulty has been experienced in'causing the heel portion of thev shoe to remain upon the last or` upon the iron follower of the jack, while pressure is being applied to the forepart'of the sole `as the heel portion of -the shoe tends torisefromthe last or follower at this point. in the pressing operation andallow the shoe'tobe'come displaced;

The objectof the present invention is to provide` means whereby this difficulty is overcome and the heel portion of the `shoe is held firmly in position on the lastor follower and the shoe is prevented from being displaced while the pressure-is being applied to the forepartof the sole.

With this objectin view the present invention contemplates providing la sole pressing machine comprising a shoe supporting jacland a cooperating form arranged' to subject the sole of a shoe supported upon the jackto a rolling pressure with a clamp mounted to move into and out of engagement with the `shoe and arranged to bear upon the sole at the heelof vthe shoe and to hol'd' the shoe upon the last or follower `while pressure is being applied to the forepart of the sole.

ItisbelievedI to be new in arolling pressure sole vpressing machinefto' provide a clamp mounted Vtolnove into" and out-of en- 'gagement with the shoe and arranged tov hear upon' the 'sole-` of'the shoe so 'astohold` I the sole .or shoe in'vpo'sitionwhile pressure is being applied to the sole, and it is accordingly' considered that-a feature ofthe cation the invention is illustrated as cmbodied in the best forni which has at present been devised and as applied to a rolling pressure sole pressing .machine similar to thatV disclosed in the patent to Tripp No. 296,486, April 8, 1884. It is to be understood, however, that except as defined in the claims the invention is not limited to use in a machine having its various parts constructed andarrangedto operate as in the machine of the Tripp patent nor is itlimited to the specific form of clamp and actuating means therefor illustrated in the drawings.

The invention will be clearly understood from.`r an inspection lof the accompanying drawing in which is' illustrated in side elevation a rolling pressuresole pressing machine embodying the same, the machine being substantially the same in construction and mode of operation as -the machine of the Trippv patent hereinbefore referred to,

but one jack and its coperating form, however, being illustrated, and so much only of the machine being shown as is necessary to showl the connection of the' present invention therewith.

Referring to the drawing 1 indicates a form supporting arm pivotally mounted at 2 in the upper front portion of the-machine frame and 3 a jack supporting arm pivotally 'mounted at 4 in the frame of the .machine below the -arm l. The jack `and form are supported upon these arms in the usual manner and the arms are so arranged that when oscillated the sole of a shoe supported upon the jack is subjected to a rolling pressure. The arms are oscillated from a main driving shaft 5 by means of a vertical worm shaft 6 connected at? its lowerend bybevel gears 7 and 8 to the driving shaftandvprovided with worms 9 and 10 which mesh with/worin` segments 11 and 12 secured to the arms"1 mounted in the arm 1 so that ayielding pressure is exerted upon the sole of the shoe supportedfupon the jack when the form and jack sup-porting arms are oscillated. The form `rcarrier 14 illustrated in the drawing is of well-known construction as will be readily seen by 'those skilled in the'art. The jack illustrated is also of well-known construction and comprises a post 15 secured 'stantiall 'Tripp hereinbefore referrred to.

t-o the arm 3 and provided at its 'upper end with. a last or follower 16 rigidly but de- `tachably'bolted thereto.

The mechanism so far described is subthe same in construction and mode of operation as that of prior wellknown sole pressing machines and more. articularly of theTIjip `Giant sole leve ing machine which is disc osed in the patent to In carrying out the present invention a clamp 17 is provided which is'secured upon the end of a rod 1-8 mounted to slide longitudinally in a blocky 19 pivotally secured to the jack supporting arm 3. The rod/18 is,y thus` mounted upon the arm 3 so as to/be cal pable of oscillating and moving longitudip nally. During the oscillating movements'ff the jack and form to subject the sole of a shoe to a rolling pressurethe rod'18 is'oscillated and moved longitudinally to bring the clamp 17 into contact withthe sole of the shoe supported upon the last or follower 16 at the heel portion of the shoe so as to hold the heel portion ofthe shoe down upon the last or follower while pressure isbeing applied to the forepart of the sole and to remove the clampv from between the last or follower 1'6' and the form so as to allow the heel portion of the shoe to be subjected to pressure. To impart the necessary movements to the rod 18 to so actuate the clamp 7 a spring 20, a bell crank 21, and a cam 22 are provided. The spring 20 is coiled around the lower end of the rod 18 and is interposed between the block 19 and a collar 23vsecured to the rod. The bell crank 21 is pivotally 'mounted upon the arm 3 and yone arm of the bell-crank is pivotally connected to the lower end of the rod 18 while the other arm of the bell crank is arranged to bear against the cam 22 which is supported from a stationary` part of ythe machine vthat lduring the inward movement of the jack/ and forni the rod v18 is moved longitudilna/lly and oscillated by the action of the spring 20 to bring the clamp 18 between the jack and form and into engagement with the sole `of the shoe supported upon the jack at the heel portion of the shoe and during the return movement of the jack and form toward the front of the machine the rod 18 is oscillated and moved longitudinally by the action of the cam 22 and the bell crank 21 'to remove the clamp 17 from between the jack and form to'allow pressure to be applied to the heel portion of` the sole.' A

collar 24 secured'to the rod 18 above the,

block 19 serves as a stop for, limit-ing the downward movement of the rod 17 under the influence of the spring 20 in case the Ajack is actuated after the last or follower 16 has been removed from the jack.

I am aware that its has been proposed to provide a rolling pressure Asole pressing machine with a clamp for holding the heel por-- tion of the shoe down 'upon the last or follower during the pressing operation, such a clamp being disclosed in the patent to Tripp hereinbefore referred to, This clamp, however, has been arranged to/bear against the upper of the shoe and in /actual practice has proved unsatisfactory. /The clamp which I have provided acts to perform its intended function in a reliable and satisfactory manner as it is arranged to bear upon the sole of al shoe at the heel portion thereof and effectiyely prevents the shoe from being displaced while pressure is being applied to the forepart of the shoe.

v"'I'am also aware that it'has been proposed to provide a rolling pressure sole pressing machine with a fixed clamp to bear upon the heel portion of the shoe sole such a clamp being disclosed in the patent to Tripp, No.

164,235, dated June 8, 1875. This, clamp, however, consists of a hook, the shank of which .is received' in a socket and is held rigidly therein by means of a set screw so that the clamp either remains'pe'rmanently in place or is removed and replaced with considerable. diiiiculty and'loss of time. My improved clamp has the. advantage that it is mounted in the machine 'so as to be movable into and out of engagement with the shoe sole and is actuated in s'uch a manner that the operator is put to no inconvenience and no loss of time is occasioned by-its use. In this'connection it may` jack.` Also it is the dst/inovably mounted Sii-.25

camas.

which is held out of engagement with the lshoe While the shoe is beingl placed on the sole clampwhich is automatically held in .engagement with the shoe. Also it is the first sole clamp which is `moved into engagement with the sole of thejjjshoe during the ctuation of the jack and Frform. According-ly Iconsider thatV certainfeatures of my invention are broad enough toinclude asole clamp having any or alll of these characterl istie features whether or .not the clamp is automaticallyvactuatedin either or bothv directions and whetherxorl not the clamp moves into and lout of engagement Withthe shoe `during 4the sole presslng operation.
