Specification of Letters Patent.

Patented July 5, 1910.

Application le'd October 28, 1909. Serial No. 525,162. x

To all whom 'it may concern.' l

Be it known that I, Lewis HACKETT, a citizen of the United States, residing at North Yakima, in the county of Yakima and State of lVashington, have invented a new and useful Last-J ack, of which the following is a specification.

struction that the last may be brought to practically any desired position.

More specilically speaking the invention aims to provide a device of this class including a last supporting standard which may be positioned at various angles, and further to provide means for extending' or expanding the last upon the standard regardless of the position of the standard with respect to its support.

It is a further object of the invention to provide, in a device of this class, a last standard mounted upon a support Vso that it may be turned to extend at any desired angle and whereby the same may be moved relatively with respect to the fixed section thereof to expand the last within a shoe being worked.

he invention further aims to provide, in a device of this class, a rotatable support carrying a last carrying standard the last upon the standard comprising' a xed and i able section of thelast whereby the same having` operative connection with the movbe moved regardless of the position assumed by the support or by the standard with respect to the support.

he invention further aims to provide, in a device of this class, a support, which is arranged to turn about an axis, a base which operative connection with the movable section of the last whereby moved regardless of the standard with which it is mounted to turn gardless of th Fig. 2 is a front elevation thereof.

As illustrated in the drawinos, the device embodying the present invention is mounted upon a base which otherwise securely fastened upon a floor or other suitable base structure, and may be of any desired form. Upon this base l0 'there is mounted an upright which is indicated by the numeral l1, and is braced in upright through the medium as secured upon it collars which are indicated by the numeral 13 and mounted to turn in these collars is 'a cylindrical sleeve 14 which depends from a which supports the last standard of the device. rIhis base is indicated by the numeral 18 and may be of any desired form and when swung upon its hinges to assume the position illustrated in Fig. 1 of the drawings, rests upon the upper end ot' the other arm 16. It may however be swung to assume a position substantially as illustrated in Fig. 3 of the drawing for a purpose to be presently described. In order to support it in this latter position, a strap 19 is secured to the last mentioned arm 16 and to that end or side of the base 18 which rests upon its upper end.

As stated, there is mounted upon the base 18 a last standard, and in order that this standard may be firmly supported upon the base, there is provided an additional suport in the nature of a head 21 which is held xedly above the base 18 by a web which is indicated Q2 this web serving also as a .hield or protector for certain mechanism which is housed therewithin.

The last standard is indicated in general by the reference numeral 23 and is fit-ted at its lower end in an opening 24 formed in the base 18 and is further fitted through an opening` 25 Jformed axiall through the head 21, it being understood that when the base 18 is in the position illustrated in Figs. 1 and Q of the drawings, the last standard will be positioned substantially vertical whereas when the base 18 is in the position illustrated in Fig.l 3 of the drawing, the last standard will extend at an angle with respect to the support previously described, it being however capable of rotation in its bearings in the base 18 and head 21 regardless of the position assumed by the said base 18. The last standard 23 is illustrated in Fig. 1 as cylindrical in form and is Jformed in one side with a groove which is indicated by the numeral 26 and extends from end to end o the same.

The last which is supported upon the upper end of the standard 23 is composed o a Jfixed heel section which is indicated by the numeral 27 and a relatively movable toe section indicated by the numeral 28. Ot these two sections, the heel section is formed or rovided with a tang 29 which is removably fitted in a socket- 30 formed or secured upon the standard 23 it being understood that by so mounting the lastupon the standard lasts of various sizes may be mounted upon the same standard without any adjustment being required. The iixed heel section 27 of as at 17 a base the last is provided with integral cheek portions which are indicated by the numeral 31 and which are located beneath the working surface or upper portion of the said section and are spaced and are iabbeted as indicated by the numeral 32 to receive a rib 33 formed upon the under side ot the toe section of the last, the reception of the rib 33 between the cheek pieces 31 and in the rabbets of the same being such as to permit of sliding adjustment of the toe section relatively with respect to the heel section. 1t will be observed that the fixed heel section embodies only the heel portion of the last whereas the so-called toe section embodies not only the toe portion of the last but also that portion of the last corresponding to the ball of the foot and to the instep. lt will further be observed that the rib 33 is of less width than the under side of the toe section of the last so that the side portions of the said section ot the last will. project beyond the planes of the side of the rib 33 and will rest at their under sides upon the upper edges of the cheek .pieces 31 ot the iixed heel section of the last whereby the toe section will be rmly supported upon the heel section when its rib 33 is inserted between the cheek pieces and in the rabbets formed therein.

Before proceeding to a specific description of the mechanism provided, as hereinbefore stated, tor relatively moving the toe section of the last with respect to the heel section, it will be well to describe at this point a means which is provided Jfor firmly holding a shoe upon the last. vThe means just mentioned is embodied in a strap 3a which is adapted for disposal over the instep portion ot the last with its end portions depending at opposite sides of the said last and last standard.

A hand lever indicated by the numeral 35 100 is pivoted as at 36 between ears 37 which are formed upon the rear side of the last standard 23 and this lever has connected to it, adjacent its handle or free end, the lower ends of springs which are indicated by the 105 numeral 38 and which at their upper ends connect permanently with the extremities of the strap 34'as indicated by the numeral 39, it being understood that these springs at all times exert a tension upon the strap 11e when the strap is engaged over the instep portion of the last upon the last standard. When the shoe is disposed upon the last, the hand lever 35 is in the dotted line position illustrated in Fig. and the strap 34e will then be under less tension than at other times, and it is dis- )osed over the instep of the shoe sole upon the last. After this has been done, the hand illustrated in full lines in the several {igures ot' the drawing so as to exert further tension upon the strap 34 and iirmly bind the same against the instep portion of the shoe sole and hold the shoe firmly upon the last. i`

1 of the drawing, ii`

lever is swung downwardly to the positiony i2 be located rearwardly of or to one side of the said pivot, whereas when the lever is swung to the full line position illustrated in the several figures of the drawing, the springs will move past the said pivot and to position forwardly of the same the relative location of the springs and the pivot being such, then, as to hold the lever in full line position.

As heretofore stated, the toe section 28 of the last. is adapted to be slidably eX- tensible in its seat in the heel section of the last and in order that this may be accomplished, means is provided which may be actuated by the foot of the operator of the device and such means will now be specifically described. The toe section of the last is formed in its under side or more specifically in the under side of its rib 33 with a socket which is indicated by the numeral 40. Within the groove 26 in the last standard 23 there is mounted to rock an arm which is composed of two sections one of these sections being' relatively fixed and indicated by the numeral 41. This section 41 of the rocking arm is the section which is pivoted within the groove 26 to rock and is formed, to one side of its pivot, which pivot is indicated by the numeral 42, with a bore which is indicated by the numeral 43 and mounted to slide in this bore is the other section of the arm which is indicated by the numeral 44. The section 41 of the arm is further formed with a slot 45 which opens into the bore in the said section of the arm and through this slot projects a handle 46 which is fXedly carried upon the section 44 of the arm.

The upper end of the section 44 of the arm is formed with a reduced portion or stud 47 which lits removably in the socket40 in the under side of the toe section 28 of the last standard, and it will be readily understood that upon rocking the arm 41, the said toe standard will be slid along in its seat in the liXed heel section 27 of the last. The lower end'of the section 44 is also reduced as indicated by the numeral 48 and a spring 49 is fitted upon this reduced end of the said section 44 of the rocking arm and bears at its lower end against the lower end of the bore or socket 43 in the section 41 of the arm, it being understood that this spring 49 serves to hold the section 44 of the arm at the upward limit of its movement and with projecting into the socket 40 its upper end Y in the under side of the toe section of the section 44 last, this upward movement of the by the engagement of the hanbeing limited dle 46 with the upper end of the slot 45 in which it works. It will be of course understood thatby grasping the handle 46 the section 44 of the arm may be slid downwardly against the tension of the spring 49 whereby to withdraw its reduced or studded upper as if away from end from the socket 40 in the said toe sec tion of the last thereby to release the section' and permit of its withdrawal from the fixed or heel section 27 of the last.

is of course intended that the toe section 28 Y of the last standard shall be normally held in the position in which it is illustrated in Figs. 1 and 3 of the drawings and that the means provided for moving this section of the last shall be adapted to shift it outwardly the heel section of the last and in order that the toe section may be normally held in the position illustrated in the drawings, a leaf spring 50 is disposed between the bottom wall of the groove 26 in the last standard and the inner side of that portion of the section 41 of the rocking arm which lies to the opposite side of the pivot to that at which the bore 43 is formed.

e means provided for rocking this arm against the tension of the spring 50 whereby to move the toe section of the last forwardly, or in other words to advance the same will now be described. A rocker 51 is mounted beneath the base 18 and to one end of this rocker is connected a strap or other flexible connection indicated by the numeral 52 the said strap being trained about a roller 53 journaled in the lower end of the groove in the last standard and being connected at its other end to the lower end of the last mentioned portion of the rocking arm. To the other end of the rocker 51, there is connected one end of a strap or other iieXible connection indicated by the numeral 54 and this latter connection is passed about a pulley 55 which is journaled for rotation in the base 18 and the other end of the said connection is attached permanently to a lever 56. The lever 56 is pivoted as at 57 to an upstanding bracket 58 upon and in order that the flexible connection 54 may be attached to this lever, it is passed downwardly through the sleeve 14 as is clearly illustrated in Fig. 3 of the drawing. This lever 56 is provided at its free end with a foot piece indicated by the numeral 59 and between this foot piece and the point of connection of the strap 54 with the lever it is formed with a laterally directed tooth or flange indicated by the numeral 60. This tooth is designed to engage interchangeably with the teeth 61 of a rack which is arranged in vertical position upon the upright 11 whereby the lever 56 may be held at any desired adjustment.

As heretofore stated, the last standard 23 is mounted to turn in its bearings in the head hold its position when turned to the desired adjustment, there is provided a means which will now be described. A bowed resilient length of wire indicated by the numeral 61 is engaged at its intermediate portion about the standard 23 and rests upon the head 21 and at its extremities this length of wire engages behind studs which are indicated by the numeral 62 and are secured on the opposite face of the said head 21. The frictional bearings had by the intermediate portion of the wire against the last standard will serve, as will be readily understood, to hold the said standard at any desired adjustment to which it may be turned.

From the foregoing description of the invention it will he readily understood that while the base 1S may be swung upon its hinges 17 so as to assume a position subst antially as shown in Fig. 1 of the drawings, or the position shown in Fig. 3 of the drawings, there will be but slight change in the location of the roll 55 with relation to the roller 63, which is mounted upon the head 15 and over which the fiexible connection 54 is passed, so that whether the base 1S be in one posit-ion or the other, the toe section of the last may be advanced and be allowed to be retracted by actuating the lever 56. It will further be understood that not only may the base 1S be swung upon its hinges 17 to assume either of the positions described and illustrated withoutaffecting the means provided for advancing and retracting the toe section of the last, but also, the last standard 23 may be rotated or turned to any desired position regardless of the position assumed by the base 18 and without affecting the said mechanism. Further, all of these several adjustments may be had and the head 15 may be turned about the axis of the sleeve 14 so as to position the last standard 23 at any desired angle, this latter adjustment being also had without affecting the mechanism for advancing the toe section of the last.
