I Application filed September 11,1901. Serial No. 75,(l43. (No model.)

T on whom it may cancer-hf Be it known that I, JONATHAN T. BROWN, of Marblehead, in the county of Essex and State of Massachusetts,have invented oer-- tain new and useful Improvements in Lasts, of which the following isa'sp'ecification; V

This invention relatesto a new anduseful improvement in lasts; and it consists inthe novel features of construction and relative IO 'arrangement of parts hereinafter fully de-. scribedin the specification, clearly illustrated in the drawings, andparticularlypointed out in the claims. g I Reference is to be had tothe accompanying drawings, forming a part of this application,

wherein like characters are used to indicate like parts wherever they occur.

Figure 1, in vertical section, shows a last constructed in accordance with myinvention,

the parts appearing in their operative position.

moved out of their operative position. Fig. 3 is a view similar to Fig. 2, showing the heel 2 5 of the last mounted upon a jack, whereby the heel may be held stationary and thefore part of the last bent down to shorten'th'e last'and remove the shoe. Fig. 4'is a detail'perspective view of the hinge. Fig. 5 is a top plan I view of a last.

1 representsa fore part, and 2 the heel part,

of a last. The rear'end of the fore part is formed with a vertical face 3 and a forwardlyinclined face 4. The front of the heel part is formed with a vertical face 5, complemental to the'face 3 of the'fore part, and with a rearwardly-inclined face 6, (see dotted line, Figs.

. 1, 2, 3,) said face 6 being complementalto face 4 of the fore part. The faces 4 and 6 are'located;

is formed with a vertical recess 7 and two parallel holes 8, extending forward from the forward wall or bottom of said recess.

Fig. 2 is a like view showing the heel tipped up to shorten the last with the parts 'lug47 for a purpose hereinafter described.

sides against the spindle socket 43.

20 represents alweb formedwith a pintle hole 21 and irregular-shaped face 22, said face terminating at the bottom' in a finger 23 and being formed at the top with a shoulder 24. The side of the web opposite the face 22 is arranged in the recess 7and is formed with two lugs 25, arranged in the holes 8 and maintained therein by pins 26, passing crosswise through the last and engaging recesses 27 in the lugs 25. By this constructionthe web 20, that forms the fore-part hinge member, is firmly and securely maintained in position.

40 represents a plate formed at the bottom of the heel of the last. This plate is formed upon its forward sidewith a face 41, which constitutes the contin'uationof the face-5 and is arranged to engage the face 3 of the fore part. (See Figs. 1 and 2.) The bottom surface of this plate forms a part of the bottom surface ofthe last and is in correct aline- '70 ment with the bottom surface of the fore: part. a W 43 represents a spindle-socket extending upward from the'plate 40. The spindlesocket 43 may be integral withthe plate or 75. secured. thereto inany desired'way. The spindle-socket 43 isfo'rmedwit'ha central recess 44, arranged to 'engagea pin '45, carried by a jack 46,'the jack being formed with'a 8o 50 represents two parallelplates of general rectangular shape arranged withtheirbases upon the plate 40 and with perpendicular The plates 50' may be integral with the plate 41 and spindle-socket '43 or secured thereto in any desired way, the purpose being to have these three sets of parts firmly united to-. gether. The web 20 is arranged bet'weenthe plates 50 and pivoted" thereto by a pin 53 0 passing through suitable apertures in the plates'50 and the web. p 4

54represent s a pin-extending through the plates 50 in the path of the finger 23 and adapted to be engaged by said finger when 5 the parts are in operative position in order to limit the downward motionof the'heel part and, together with the faces 3,4, and 41, v to maintain the last in itsoperativeposition.

60 representsa detent pivoted between the plates 50 at their upper sides by means of a pin 6i passing through suitable apertures in the plate and said detent.

2 represents a spring arranged between a pin 63, carried by the plates 50, and the rear end of the detent 60 for the purpose of forcing the front end of said detent yieldingly downward in order to have said detent engage the shoulder 24 of the plate when the heel 2 is thrown down in the position shown in Fig. 1. The parts are so arranged that when the spindle 43 is put upon the jack (see Fig. 3) a lug 47 engages the rear end of the detent and unlocks the same, thereby permitting the relative movement of the fore part and heel part toward each other to shorten the last.

It will be observed that the detent 60 is in an exposed position, with the end that is to be engaged by the ing 47 of the jack in proxitnity to the outer end of the hollow spindle 43, so that the said detent will be unlocked by the engagement of the lug -t7 of the jack without permitting any portion of said jack to actually enter the last. Moreover, since it is not necessary that the lug 47 of the jack shall enter a hole formed in the last it is not necessary to accurately apply the last to the jack, thus saving time in placing the last on the jack.

In practice the fore part and heel part are suitably shaped, the recess 7 and holes 8 in the fore part are formed upon suitable jigs, and the plate 20 and its parts secured in position. A similar procedure is followed in the mounting of the plate 40, spindle-socket 43, and plates 50. The arrangement is such that the last is maintained against all strains to which a last is subjected, while at the same time the last may be readily shortened 0r rigidly locked in operative position, as desired.

Having thus explained the nature of my invention and described a "Way of constructing and using the same,although withoutattempting to set forth all the forms in which it may be made or all of the modes of its use, I declare that what I claim is 1. A hinged last, comprising a fore part, a

heel part, a web, parallel lugs upon said web arranged in complemental recesses in said fore part, a heel-plate secured to the heel part and forming the bottom surface thereof, a spindle-socket-projecting from said plate, two spaced parallel ears upon said plate in advance of said spindle-socket, said Web being arranged between said ears, and pivoted thereto.

2. A hinged last, comprising a fore part, a heel part, a Web, parallel lugs upon said web arranged in com plemental recesses in said fore part, a heel-plate securedto the heel part and forming the bottom surface thereof, a

arranged in complemental recesses in said fore part, a heel-plate secured to the heel part and forming the bottom surface thereof, a spindle-socket projecting from said plate, two

spaced parallel ears upon said plate in advance of said spindle-socket, said Web being arranged between said ears, and pivoted thereto and a detent carried by said ears and arranged to engage said web above the pivot of the last.

4. A hinged last comprising a fore part, a heel partformed with a spindle-socket, a hinge connecting the fore part and heel part, and a detent for locking said parts in operative position, said detent being located in an exposed position adjacent to the end of the spindlesocket.

In testimony whereof I have affixed my signature in presence of two Witnesses.

JONATHAN T. BROWN.
