Patented Oct. 14, 1930 uma sTATEs PATENT oFrlcE JOHN S. HANSEN, DECEASED, LATE OF BROCKTON, MASSACHUSETTS, BY ELWINE Gr. HANSEN, EXECUTRIX, OF BROCKTON, MASSACHUSETTS, ASSIGNOR TO O. A. MILLER TREEING MACHINE COMPANY, OF PORTLAND, MAINE, A CORPORATION OF MAINE SHOE FORM Application filed April 27, 1925. Serial No..26,111.

This invention relates to shoe trees and stretchers and is illustrated as embodied in a tree to be used for keeping shoes in shape during periods when they, are not being worn.

It is commercially important that such forms be inexpensive and, in order to secure the requisite quantity production of eachV size of form, the number of differentsized articles corresponding to a line Vof sizes and widths of shoes mustbe very small. Accordingly, and in orderV that the use of such forms may be economical to the purchasers,

the same form or tree should serve for numerous diiferent styles and sizes of shoes. In view of these considerations, such=a form should be adjustable for length and should have a considerable range of expansion in its forepart. YSuch forms or trees are therefore often found provided with a split expansible forepart which is operated by throwing a longitudinally expanding toggle which unites the forepart and the heel part: the length adjustment being advantageously secured by making this toggle adjustable in length.

A considerable number of devices vfor expanding the forepart members have appeared. They generally involve a pair of toggle links connecting the forepart member to the operating member, or a plate with converging slots operating on pins in the forepart members, orl vice versa. Such devices have all failed to give satisfaction, because, among other reasons, they do not provide for keeping the forepart members in alinement; they separate them, it is true, but there is nothing to prevent one forepart member from running into the shoe ahead of the other, and remaining so relatively displaced. This sort of performance frequently occurs and pulls the shoe out of shape.

Tt has been attempted to vmeet this difficulty by inserting a wire nail horizontally transversely in the toe ends of the forepart members, the head end of the nail being slidable in its forepart member. This construction, however, often sticks and gives a great deal of trouble. Y

It is a principal object of the invention to overcome this and other diiculties, by the provision of means for holding the forepart members in proper alinement at all times, so

that they willl aways move evenly into the shoe. As disclosed, this means comprises a plate attached to the forepartY members soas to prevent relative longitudinal displacement, and cooperating A'with the toggle member to maintain the proper alinement.-

It is a further object of the invention to provide an improved adjustable toggle mechanism for expanding the tree. A feature of the invention in this aspect consists in an adjustable pivot pin for the .toggle having a rebentend engageable with any one of a plurality of notches in the side of a slot in a toggle link along which the main body7 of the pin is movable.

These and other features ofthe invention comprising certain combinations and arrangements of parts will be understood from the following description of a preferred embodiment thereof selected for purposes of illustration and shown inthe accompanying drawings in Which,

Fig. 1 is a perspective view of the tree.

Fig. 2 is avertical `section on the plane indicated by 2-2 in Fig. `1.

Fig. 3 is a horizontal section on the line Fig. lis a vertical section on the line 4.-4 of Fig. 3.

Fig. 5 is a similar section showing the toggle unlocked. Y j

Fig. 6 shows the two plates used in the tree.

The forepart is split into two members 10 by a vertical longitudinal cut. The inner faces of these members are slotted at 12 and cut away at 14 to receive the operating means. These means comprise a spreader plate 16 having atv its forward end a pair of forwardly converging slots 18 each engaginga pin 20 in one of the forepart members 12. It is clear that projecting the plate 16 forward and backward will spread and retract the forepart members respectively.

In a hole 22 at the rear end of the plate 16 is pivotally mounted the front end of the toggle link 24. This link is punched and slotted at its front end as at 26 to receive the tongue which lies to the rear of the hole 22, and the slot is then pounded shut in assembling the device.

The link 24 is slotted as at 28, and the bottom of the slot is extended in a number of semi-circular depressions or notchesl 30. The link 24 is embraced bv a sleeve 32 arranged to slide along it. The sleeve lit-s the link 24 vertically, but provides an opening about twice as thick as the link 24, and is open at one side of its bottom, as at 34.

The sleeve carries a pin 3G which is rebent` upon itself at 38, and can slide back and forth laterally through the sleeve, the holes inthe sides thereof fitting the single and the double portions respectively of the pin. A spring 40 restino against the sleeve and the head 4l of the pin tends to push the pin to the right in Fig. 4. The main part of the pin is in alinement with the slot 28. and the rebent part with the notches 30. llVhen the parts are in the position shown in Fig'. 4, the sleeve 32 is locked on the link 24: when l the pin is thrown to the left as in Fig. 5,

the portion 38 slides out of the notch 30 and the sleeve can be adjusted back and forth on the link to set the pin into another of the notches 30.

A second toggle link 42 is pivoted on the pin 36 inside the sleeve, beside the link 24, and is permitted to swine; downwardly around the pin as shown in Fig. l through the opening' 34. It can swing); upwardly around the pin to a slight extent before coming in contact with the upper side of the sleeve, the pin hole in the link 42 being somewhat above center in order to effect this. The heel part 44 is fastened to the rear end of the link 42.

The pin 3G being in any desired position of adjustment, the device is inserted in the shoe with the forepart members closed together and the toggle bent with the heel part down in the heel end of the shoe, and the straightening of the toggle forces the forepart into the shoe and spreads it. The link 42 can swing 'upwardly beyond alinement with the link 24 sufficiently to bring the pivot Vpin 36 below the line joiningthe outside ends of the toggle links so that the device will stay in pla-ce under pressure. The length of the toggle can be adjusted to the shoe by putting the pin 36 into the proper notch 30. A thumb piece 46 is provided on the sleeve to assist in throwing thel toggle.

So far nothing; has been described which will prevent the forepart members having a dissimilar or uneven movement when the tree is forced into the shoe, and the means for accomplishing' this result forms an important feature of the invention.

This means, in the embodiment of the invention shown, consists of a plate 48 having a longitudinal slot 5,0. at its rear end and two t ansverse slots 52 in its forward portion. rlhe pins 2O pass through the slots and the link 24, which is here formed as a vertical "at plate, plays in the slot 50. lhe link and plate can turn relatively in a vertiftal plane and. slide relatively in a horizontal plane, but no substantial horizontal relative rotation is possible. 'llhus the pins 20 will always be kept on a line perpendicular to the link 24, though the distance of this lino from tne end of the link will vary the pins are moved toward and from each other by the advance and retraction of the link 24 and spreader plate i6. The forepart members can thus pivot about the centers of the pins 2O as they are separated to lit the contour of the shoe. but are always he] d in transverse alinement, since neither pin 20 can get ahead of the other. In ot ier words the horizontal orientation of the forepart members relatively to the heel part.

preserved.
