Specification of Letters Patent.

Patented June 12, 1911?.

Application filed February 5, 1916. Serial No. 76,433.

To all whom it may concern:

Be it known that I, CHARLES G. MARKER, a citizen of the United States, residing at the city and county of Denver and State of Zolorado, have invented certain new and useful Improvements in Shoe-Stretchers, of which the following is a specification.

My invention relates to an improvement in shoe-stretchers, and the object is to provide a simple device of the character mentioned, which may be accommodated to various sizes of shoes, provision being made for removable and interchangeable parts, and which may be adjusted and have the desired application of power for stretching the shoe either lengthwise or widthwise, or both, after which the means for applying the power or pressure may be entirely removed.

With the foregoing in view, this invention comprises a frame, a sectional last detachably connected with the frame, thereby admitting of interchangeability of lasts, a heel-plate, detachable means for effecting an endwise movement of the heel-plate, and also of a spreader, whereby the shoe can be lengthened or stretched endwise, and broadened or stretched widthwise, or both, and means for automatically locking the stretcher in the adjusted position.

In the accompanying drawings:

Figure 1 is a plan view;

Fig. 2 is a view in side elevation, with a side of the frame removed;

Fig. 3 is a vertical longitudinal sectional view;

Fig. 4c is a transverse section;

Fig. 5 is a horizontal section through the last sections and the forward end of the stretcher;

Fig. 6 is a detached view of the heel-plate and rack;

Fig. 7 is a detached view of the last spreader and rack;

Fig. 8 is a view of the hook on the rear of the last sections;

Fig. 9 is a View in perspective of the op erating lever; and Figs. 10 and 11 are views of modified forms showing the arrangement of applying patches to the last in order to give additional pressure to certain parts of the shoe.

A, represents the frame, preferably made of sheet-metal, and bent to form a bottom and two sides. Three pins, namely 1, 2 and 3 extend across from one side of the frame to the other, they having their ends upset to hold them securely in place. Fitted within the bottom and adapted to slide thereon are the two ratchet-toothed bars 1 and 5, one of which is divided through the center to form two parts which straddle the ratchet-twthed bar 5, forming lateral guides therefor. The teeth of these bars extend in opposite directions. Bar 5 enters the frame through slide 5. To the rear end thereof, a curved heelplate 6 is secured, it being adapted to fit and press within the heel of the shoe.

The forward end of the divided ratchettoothed bar 4; terminates in a rouiuled and somewhat elevated tongue 7.

Gravity pawls 8 and 9 are pivoted on the pin 2, their lower ends resting upon the ratchet-teeth a and 5 respectively, and acting to automatically lock the bars in their outwardly adjusted position.

The last is made in two half sections 10 and 11 of corresponding size and shape, the division between them being vertically through the longitudinal center, and when together forming an ordinary shaped toe last, they being adapted to enter and fit the toe of the shoe. These sections are provided with cavities 12 and 13 at the rear, the forward ends of which are provided with the cam inclines 14, 14, in position to be engaged by the forward end of the tongue 7, which, when forced forward by crowding against the cam inclines 14, 14, acts to spread the toe-last to stretch the shoe widthwise.

The inner faces of the rear upper ends of the last sections are rounded as at 15 to admit of this spreading.

Right-angular hook-plates l6, l6, (illustrated in perspective in Fig. 8) are shown in the angles formed in the rear ends of the last-sections, they being adapted to be removably hooked over the pin 1 at the forward end of the frame, thus admitting of interchangeability of last-sections, accord ing to the size required for the particular shoe to be stretched.

A hand-lever 18 is provided with notches 19 and 20 and V-shaped claws 21 and 22 at its opposite ends, the notches being adapted to receive and admit of fulcruming on the pin 3, and the claws being adapted to take in the teeth of the racks, the divided wider claw 21 operating on the rack 1in one di rection, and the smaller one on rack 5 in the opposite direction, they being placed respectively on opposite sides of the pin 3, ac-

cordingly as they are to move the racks l or 5, and upon which the lever is turned as a fulcrum.

It is obvious that all these parts might be in various sizes; also that the last-sections may be easily removed and replaced or interchanged as to size; and likewise that when removed, the racks may be withdrawn from the frame by pulling them outwardly in opposite directions and different sizes of racks substituted if desired, the last-sections when in place preventing the removal. of the divided rack 1-.

By using the back ratchet 5, the fore part may be forced into the extreme end of the shoe and the boxing raised or spread as desired, while if the shoe requires stretchingin width alone and not in length, the last may be pushed forward with the back ratchet 5 before spreading the lasts 10, 11, it remaining in exact position, due to the fact that the back ratchet prevents its slipping back.

I claim:

1. A shoe-stretcher comprising a frame, substantially U-shaped in cross-section, last sections secured to said frame, a heel portion slidably mounted in said frame, and a step by step mechanism slidably mounted in said frame for spreading said last-sections or operating said heel portion.

2. As an article of manufacture, a shoestretcher comprising a U-shaped frame, lateral braces therefor, last-sections detachably mounted upon one of said braces, removable rack-bars slidably mounted in said frame,

and a detachable member adapted to cooperate with said rack bars and one of said lateral braces to spread said last-sections with a step by step movement.

3. As an article of manufacture, a shoestretcher comprising a U-shaped frame, lateral braces therefor, last-sections detachably mounted upon one of said braces, removable rack-bars slidably mounted in said frame, a detachable member adapted to cooperate with said rack bars and one of said lateral braces to spread said last-sections with a step by step movement, and a heel-plate on one of said rack-bars operated through the cooperation between said detachable member and said lateral braces.

f. A shoestretcher comprising a frame having parallel edges, lateral braces be tween said edges, last-sections, and rightangular hook-plates fastened to each of said sections, and provided each with a notch, the last-sections so arranged as to normally hook vertically upon one of said lateral braces, said parts being engaged by the notches in said right-angular plates, said hook-plates being normally in planes substantially parallel with said sides.

5. The combination with a frame having pins thereacross, and two rack-bars fitted in the bottom of the frame and slidable therein from opposite directions, one having a heel-plate, and the other a rounded tongue at the end, of removable last-sections having hooks whereby to detachably fasten them to one of the frame-pins, and provided with a cavity with inclined forward ends to receive and be engaged respectively by the tongue, detachable means adapted to fulcrum on one of the pins for forcing the racks endwise, whereby to stretch the shoe both lengthwise and laterally, and automatic means for locking the racks in their adjusted positions.

6. The combination with a frame having three pins thereacross, one having gravitypawls pivoted thereon, of last-sections detachably hooked to one of the pins, rackbars slidably supported upon the bottom of the frame adapted to be locked by said pawls one having means for spreading the last sections apart, and the other having means for engaging the heel of the shoe to be stretched, and means cooperating with one of said pins on said rack-bars, whereby the rack or racks may be forced endwise by the swinging of the lever.

In testimony whereof I affix my signature.

CHARLES Gr. MARKER.
