LASTING APPARATUS.

Patented Nov. 30, 1915.

Application filed January 6, 1912. Serial No. 669,773.

To all whom it may concern Be it known that I, G s'r r a citizen of the United States, residing at Marlboro, in the county of Middlesex and State of lvlassachusetts have invented certain improvements in Lasting Apparatus.

of which the following description, inconnection with the accompanying drawings,

is a specification, like reference characters on the drawings indicating like parts in the several figures.

This inventionrelates to apparatus for lasting the toes of boots and shoes, the object of the invention being to provide a cheap, simple, compact and easily'operated mechanism with which the uppers may be quickly and smoothly lasted, the illustrative embodiment of the invention herein shown being adapted for light work in lasting which a large output is desirable.

The several features of the invention will be disclosed in the following description of" the illustrative apparatus, taken in connection with the accompanying drawings, and will be particularly pointed out in the claims. a V

Referring to the drawings :,Figure 1 is a front elevation of my improved lasting apparatus showing a shoe in position to be lasted and a portion of abench in section. Fig. 2 is an enlarged plan View, partly broken away, of the lasting devices, with a portion of a shoe illustrated in connection therewith before the toe is lasted. Fig. 3 is a plan view, similar toFig. 2, illustrating the position of'the respective parts of the apparatus and a portion of a shoe with the toe lasted, Fig. & is a'frontelevation of the lasting devices, the same being partly broken away to save space in the drawings.

Fig. 5 is a detail end elevation of the lasting devices with a last in section in connection therewith, illustratmg the manner in which the toe portion of the upper is wipedover the last by the wipers. Fig. 6 is a detail plan of the toe wipers. Fig. 7 is a detail plan of the toe clamp. Fig. 8 is a longi tudinal section of a last, with an upper in position to be lasted. Fig. 9 is an illustrative section, similar 'to Fig. 8, showinga por on of t l s ing dev es ho in t e upper the pos tio w ch. ass med, as the lasti g s cretio lot he me beg ns, his r e be.- in were 9&9. liig- 2 9 is, an l st a seeae i was e-F 9, shoe.-

BERGMAN,

a heelpost 15 and a toe rest 16. A bellcrank lever 17 is pivoted at 18 to a bracket 19 fast to said bench, the horizontal arm of said bell-crank lever being connected by a link 20 to a treadle 21 pivoted at 22 to a bracket 23 fast to the floor, said treadle be-;

ing held upwardly by aspring24: connected at one end to said treadle, and at the upper end to the bench 12. A collar 25, fast to the link 20, limits the upward motion of the treadle 21 and the baclqvard rocking movement of the vertical arm of the bellcrank lever 17. i

A pair of crossed levers resembling pincers26 is pivoted at 27 to the upper end of the vertical arm of the bell-crank lever 17 and to the lower jaw 28 of said pincers is pivoted at 31 a pair of

toe wipers

29, 30, said toe wipers being shown as round rods bent intov approximately horseshoe shape and adapted to swing in a horizontal plane, or a plane substantially parallel to the sole of the shoe. The

lower arms

33 and 34 of a second pair of crossed levers or pincers 32 are pivoted at 35 and 36, respectively, to the

toe wipers

29 and 30, andthese arms are extended downwardly below said toe wipers and are provided with

lateral projections

37 and 38, which extend, respectively, through

holes

39 and 40 formed in the guide arms ll and 42, said guide arms forming, in effect, a single U-shaped piece per jaw 46 of the pincers 26, said clamp plate being preferably of U-shape. The approach of the toe clamp plate 4-5 to the toe WI-329 30 is esu at d y mea of adjusting screw 47 having threaded en; eas ment w th said upper i 4.6 an abu ins aga nsthe l er iav' 218 1 the a icers closed iz-movies thezhaedles i8 relation to the last as shown for illustrative purposes in'Fig. 8, the operator depresses the handle 19 to raise the toe clamp plate 45 away from the

toe wipers

29 and 30.

At this time the free ends of the

toe wipers

29 and 30 are held apart by the action of the

handles

50 and 51 of the second pair of pincers 32. The operator now folds the upper 13 of the shoe over the

toe wipers

29 and 30 and the toe clamping plate 15 is brought downwardly by moving the handles of the pincers 26 together until the leatherof the upper is clamped between the under side of the toe clamp plate -15 and the upper side of the

wipers

29 and 30, Fig. 9, and is pulled upwardly about the toe of the last. The operator now presses upon the treadle 21, rocking the bell-crank lever 17 upon its pivot 18 and moving the two pairs of pincers with the toe wipers and toe clamping plate forwardly or to the right (Fig. 1), said parts being carried automatically downward about thepivot 18 as they are moved forwardly. This draws the upper overthe toe of the shoe, as illustrated in Fig. 10, and while this is occurring the op-v erator moves the toe wipers towardeach other and applies downward pressure upon the end portions of the wipers by manipulating the handles of the second pair of pincers 32, swinging the free ends of the toe wipers inwardly toward each other and wiping the sides of the toe portion of the upper firmly over the inner sole of the shoe, as illustrated in Fig. 5. By pressing laterally the second pair of pincers, as distinguished frommerely closing them, the operator can close one wiper farther than the other one as may be required for the shape of the shoe. The sole may be coated with adhesive to secure the upper or the operator may now tack the toe portion of the upper to the inner sole, or fasten it thereto inany desirable manner. He then releases thetreadle 21 and opens apa'rtqthe handles of the

pincers

26 and 32, the parts resuming the relative positions illustrated in Fig. 1. He next removes the shoe and the apparatus is in condition to operate upon another shoe for the purpose of drawing the toe of the upper over the last as hereinbefore described.

' It will be understood that the handles 48 and 41-9 of the pincers 26 are joined together by a pivot 53, the jaw 28 being an extension of the handle 48 and the jaw 46 being an extension of the handle 49.

Vhile I have described my invention as embodied in apparatus for lasting the toes of boots and shoes, it is evident that some features of the invention are also useful in apparatus for lasting the heel portion of the uppers of boots and shoes.
