SHOE-JACK; I

To all whom itmay coacera:

Be it known that I, PHILlP. Bncnun of Utica, in the county of Oneida and State of New York, have invented certainnew and useful Improvements in Shoe-Jacks; and I do hereby declare that the following is a full, clear,,and exact description there of, which will enableothers skilled in, the art to which it appertains to'make and use the same, reference being had tothe accom palnying drawingaand to the referenceenu-r merals marked thereon, which form part of this specification. we a My present invention relates to shoe-jacks such as arejused by shoemakers and shoerepair men to support the last indesircd position. v

The object of my invention is to provide a shoe-jack that is simple in construction and eflicient in operation and readily adapted to be used under varyingconditions for a great variety of work.

A further object of my invention is to provide a device of the class described that will securely hold the last imposition and t that willreadily admit of the last being detached from the jack and replacedthereon or replaced with another/last. a

A still further purpose of my invention is to provide shoe-jack that will hold the last in such a manner that aishoe may be readily placed upon the last and removed about thereon or entirely removed therefrom without interfering with the grip of the jack upon the last -and without any part of the jack coming into contact with the shoe and without any part of the shoehaving, torest upon the ack.,

A further purpose of my invention is to provide a shoeejack that may "be moved about into any position without relaxing its hold upon the last and which maybe operated to grip or release the last in any position when so desired. H Further objects and advantages of my invention will appear from the description of the device hereafter given and the claims thereupon made. '1 a Figure 1 is a sideelevationof a. shoejack embodying my invention. ,F-ig. Q is a sectional view on-an enlarged, scale on linev 2-2-of Fig. 1. Fig. 3 is a-view on an en larged scale of a last suchas is used with my jack, showing the upper side of. the last Specification of Letters Patent Patented Aug, Application ma 27, 1915.

l liefer'rin'gto the drawings in am ore par ticular, description, there is shown astrong upright 5 secured in any desired placeas against a bench (not shown) upon which upright is provided a strong clamp 6.foperated bywinged nut 7 so as to pivotally hold on'a horizontal axis the bracket 8, the outer end of which 8 when the said bracket is in its ,usual lowered position over shangs a rigid element such as offset 5 on the upright 5, In the bracket Sis rotatably mounted with its axis atright angles to the axis of the pivotal clamp 6, the depending shank ening material. The base is secured to the" bracket by suitable means engaging the end of the shank?) projecting from its bearing in said bracket 8 as by means of nut 1i and lock nut lfiengaging the threaded extended end of said shank 9, a washer 16 being interposed between nut 1st and the adjacent surface of bracket 8. 'VVhen the bracket 8 and the shoe-jack is in its usual lowered Pos tion as shown in Fig. 1 theend of shank 9 and the lock nut 15 will rest against the extended portion 5 of the base thus affording a solid support directlybeneath the shoej ack.

Removably supported by the upper end of the upstanding arm 12 is last 17 through the upper or ankle surface 18 of said last being placed directly over the upper end of said arm 12, preferably with washer or packing 19 "or similar sound-deadening ma terial interposed therebetween. Extending intothe lastvfrom the said ankle surface 18 I is a hole 20 into which removably fitsthe upper end of pin 21 which projects upward from the upper end'of arm 12 and which is operatively connected to yielding or springtensioned means tensioned to force; the upper end of said pin 21 radiallyiof the upper end of said arm 12in about the direction in which the beak 11 extends from the base 10. Convenient means for 7 so yieldingly forcing said pin 21 in the direction desired may consist, of spring" 22 located in the chamber 23 in which thepin 21 isswingingly or movably mounted on pivot 24in thecupper end of arm. 12 and interposed between'the pin 21' and one of the walls of said chamber 23 so as to force the upper end of said a'rm in the said direction butadmit of I the arm being retracted upon suflicient force being used to allow the last to be looked upon the shoe-j ack as hereinbefore described.

f The instep of. the last 17 on its side away "from the sole is provided with arecess having refe'ntering sides ora' dovetailed mortise 33 formed by over-hanging sides 34; and

'withits end towardthe toe of the last open. I

Into this open end mortise is adapted to be placed the oppositely-shaped or tenon end 25 of brace 26 which extends diagonally downwards and away from arm 12 and has its lower end slidingly and removably but nonrotatably fitted uponbeak 11 by'means ofa hole 27 in the lower'end of saidbrace'fitting upon said beak, said beak in cross'section and said hole 27 being similarly shaped'as by being rectangularso as to holdthe brace '26 from any rotating motion upon the beak.

The operation of my shoe-jack is as follows: The operator places the last 17 of the desired size 'with its sole upward upon the jack by fitting the hole 20 over the up wardly projecting pin 21 on'upstanding 7 arm'12 and with the open ended mortise 33 above the beak 11. The brace 26 is mounted upon the beak 11 and slid inwardly thereon and its tenon-25 inserted in the mortise 33.

Then by reason of the yieldingly tensioned pin 21 and the diagonal arrangement of' brace 26,Vthe parts may be clamped or locked together so as to hold the last upon'the top of the shoe jack until it is purposely re- 7, 'moved therefrom. This locking together is effected through the pin 21 urging the last forward or to the right as the parts are shown in'Fig. 1 and keeps the heel of the last from being moved from its position i above arm 12 while the mortise and tenon connection between brace 26 and last 17 prevents thelast from being. removed by upward motion thereof, and the diagonal arrangement of brace 26 cooperating with pin i 21 keeps the brace 26from becoming disengaged from the last 17. The tendency of pin 21 to move to the right "as indicated in Fig. 1 also cramps or 'tends'to: swing the upper end of-arm 26 to the right and thus takes up any slight loosenessthere may be in the mortise and tenon joint at the top ofsaid brace or its sliding connection with the" beak the lower end of: the brace and thusholds the last rigidly in place without 'any loosenes's in the joints of said jack or its connectionwith said last. It will beseen that with the last solocked tothe jack the last and 'jackm'ay be swung about to any .angle upon its clamp 6 which holds the bracket 8 to the upright 5 and without in anyway affecting the rigidity of the look ing engagement effected between the jack and the last; Similarly it will be seen that the last may be-turned about in any direction upon the shank 9 'jo'urna'led in its bearoff of pin 21. The last may be again re placed on the jack or another last of similar or different size but having similarly ar-'.

ranged .hole20 and open ended mortise 33 may be placed on the jack by following the direction above outlined in detail, it being understood that the same brace 26 fits all sizes of lasts.

As the parts of the jack directly connected to the last are connected to thelast upon its upper or ankle side away from the heel and at the upper side of the instep it will be obvious that a shoe may be readily-placed upon-the last or removed from the last withr out detaching the last from the jack or changing its position upon the jack. i=Moreover, it will be seen that at no time does any part of the upper of theshoe come into contact with the'jack'nor 'does any part of the shoe upper have to rest upon any part of the jack nor stand any ofithe strain of hold-, ing the last in place on the jack nor strain of contact of holding the shoe upon the jack. 7 Again'it'will benoted that a jack constructed according to my invention will be operative both to hold the last inplace or to have the last placed in position or removed therefrom without regard to the angle or position in which the jack may be or may be moved to. It will be understood that while the pivotal mounting of the jack base 10 upon the bracket 8 and the pivotal I mounting of thatbracket in clamp 6 is convenient and desirable such pivotal connec tions are notessential to my invention.

Whenever it is desired to fasten a shoe upon the last 17 in addition to the fits of the shoe upon the last, a strap may be placed about said shoe and passed downwardly through a slot 28 provided in the base or .oth'er convenient pa'rt of thejackfi There is no possibi-lity of the last becoming loose no mattcrin what position thej'ackj be placed nor is there any possibility of the last being drawn upward from the jack when i the shoemaker attempts togdraw an awl up from a shoe uponthe -last."i "Assoon as the last is adjusted in operative position upon the jack the shoemakerhas the full use of both his hands for working upon the shoe. It will thusbe seen that I havejprovided a shoe-jack which-positively locks the last to the jack in a firm manner'and yet which allows the last to be very readilyre moved when desired from the jack.

If it is desired to place the last upon the I; jack with the shoe already upon the last or to remove the last from the jack with the shoe still upon the last this may readily be i done with most sizes and styles of shoes since the position of the upper end of brace 26 just before it is mserted in the mortise or after it is removed from themortise is brace 26 and extending therethrough into engagement with the beak 11. Setting this screw against beak 11 renders the last nondetachably attached to the jack either purposely or accidentally until the thumbscrew has been loosened.
