Y Application filed August 1,

T all whom it may concern:

,Be it known that I, CriA'aLEs F. PYM, a' citizen of'Canada, residing at Esseiz; the

Province of Ontario; Canada, have invented an Improvement in Lastin -Machines, of

which the following description, in' connec tion with the accompanying drawings; is a specification, like letters j'on the drawings" 7 representing like parts.

more'at length in the course of the following" description, reference being had to 'the'-'accompanying drawings, in which I"have'" shown a tion;

preferred embodiment of my inven In the drawings: Figure Us a perspective view of a lasting machine provided witl'i my vation, the lower part beingin section, show improvements;'Figs. -2 and 3 are fragmen' tary details in top plan and si'de'elevation of the fiattener whichoperates with the wiper of the machine and with the lasting jack for permitting the shoe to be swung around and handled readily; Fig. 4 is a central longitudinal section view of the lower portion of the jack support; Fig. 5is a view in front eleva tion thereof; and Fig. 6 is a view in front eleing the upper part of'the' jack and illustrating its movement in dotted lines. 1

It will be understood that my'imnrovements may be used with any usual fasting machine, the form herein shown comprising a head 1 on a suitable pedestal 2 provided with tack driving mechanism, consisting of a by an arm 6 and eccentric 6 the tacks a stirrer rod 8 and wormwhe'el 9 andwornr 10 from a shaft 11."

Cooperating with this fea- 11o turein steadiness and aiding in'holdmg the shoe in proper osition as it is turned and shifted about, an also aiding in flatteningthe crim edleather, is 'a nozzleffoot or. flattener bloc 42, clamped immovably at the j e '3 by any suitable iewer, end of the nozz meansyas by a'scre'w 43. The crimper 12 is bifurcated to straddle this fiattener42, therei by cooperating therewith to wipe down and lie-crimp. the upper. Not only does this flatform depth, and it helps to make a flat seat and't o 're'vent the upper from being trapped or'ca when 't e upper is short at the seat, as ejquentlyhappens. Undersuchcircumstances T I, it has been common heretofore for the leather to catch between the nozzle and wiper and either tear the leather or bend-- or break the nozzle. 4 I can best describe the operation of my inventionin connection with lastingheel seats. When the jack moves down away from the nozzle and wiper, due to the upward movement ofthe crank 29, which lowers the rocker so arm 27 and thereby depresses the jack, the operator feeds the shoe forward by swin ing t e spindle slightly on its pivot 17, the ack immediately rises and forces the shoe against i the nozzle-footrest or flattener 42 with a 3'5 stro force, operating to flatten the seat and crow and press the leatherdownstrongly a ainst the T hel s the wiper with its work, preventing the ormation o a ridge in the leather be 40 tween the edge of {t e shoe and last and the nozzle. The flattener 42 spreads or distributes the pressure of the jack and makes the work much more even. It'cooperates with v the constant up=and-down motion of the jack 45 to hammer vthe heel seat, as well as smooth and iron the same and prevent the trapping of the leather, already mentioned, and it gives a broad bearing "on' which to swing and move the shoe, tending to help maintain the shoe in roper position in connection with the spin le support 15.

' If the operator desires to move the shoe temporarily nearer or farther from the wiper and tack driver, he can do so simply by swinging the entire jack in opposition to the s ring-held arm 36, without changing the 0 amp 40. The latter is adjusted to suit different sizes of shoes and styles of work, and is for the purpose of giving steadiness of movement and aiding the operator in directing the Patent is, l

t betweenlt e nozzle andthe w1 er' ast' on which it is being lastedmovements of the shoe. The jack is always in its highest position or point of travel when the tack d'rlv'en, at which time the shoe is heldfirmly a ainstthe nozzle'and flattener, theresult being that the tacks are driven 6 into the shoe evenly "and are properly and m idly clenched. I d Y aving described my invention, whatI claim as new and desire to secure by Letters 7 1. In a lasting machine, a tack driver, a reciprocatory wiper, and lasting jack, and operating means therefor operated in timed relation to the tack driving, said lasting jack and its operating means pressing the last and. 7 shoe vertically up at the time of tack-driving against the wiper and tack driver in opposi-' tion to their downward pressure on the bottom of the last, the aforesaid mechanism including means for hammering verticallythe 8 crimed leather down u on the bottom of the ast' as it is being aid by .the wiping movement and pressure of said wiper.

2. In a lasting machine, tack-driving mechanism and its operating means, awiper, 8 operating means therefor operating in timed relation to the tack-driving mechanism, to

engage the shoe when a tack is driven, a jack for holding the shoe with relation to said tack driving mechanism and wiper, and 9 automatic means for forcing said jack and its shoe strongly against said Wiper each time a tack is driven. I v

3. In a lasting machine, tacking mechanism including a nozzle, lasting, mechanism 9 including a lasting jack, means forimparting an up-and-down feeding movement to said jack with relation to said nozzle, and a'laterally extending flattener block fast on the lower end of said nozzle for cooperating with 1 said lasting jack in flattening the leather and steadying'the work.

4. In a lasting machine, a tack driver provided with a nozzle, a reciprocating wiper operating in line with said nozzle, said wiper 1 havin a bifurcated crimping end, and a narattener block extending rearwardly over the edge of the last in line with said wiper to rest on the shoe between the proj ecting endspf the wiper as the latter recipro- 1 cate, for preventing injury to the leather and aiding in flattening the crimps of the leather and steadying the work.

In testimony whereof, I have signed my name to this specification, in the presence of 1 two subscribing witnesses.
