l s claims. (c1. 12-12s;z

the mid-portions of spaced coil springs whichj coact with the forepart sections at points spaced e This invention relates to expansible shoe trees e intended to be placed in shoes when not inuse `for preserving their original appearance and shape. The sale of shoe trees having rigid shoe engaging sections made of metal or wood is very fmuch limited `by the fact that, in order to fit a all sizes of shoes, a retailer is required to carry astock of a considerable number of sizes and this he is not always willing to do. Shoe `trees have been provided, therefore, which have expansible foreparts and extensible heel parts, so

that the tree will more readily ll the shoes of diierent shapes and sizes, both `transversely and F lengthwise of the shoe. To be satisfactory, such `a tree must be arrangedso` that the forepart sec tions may readily assume the positions which they are tooccupy in any particular shoe without binding and this has not been found in prior shoe trees, because of the tendency of the coiled expansion springs commonly employed to catch upon the` recesses provided to receive them in the forepart sections, or to catch upon the screw which sometimes has been employed as a combined limiting means and spring support for said expansible forepart sections.

If a tree with an expanded forepart is provided with springs strong enough to cause the tree to y rmly ll the shoe, then the user may encounter difficulty in inserting the forepart of the tree into the shoe. sometimes used for positively collapsingthefore-` part` and holding it in `collapsed position as the tree is inserted. `One form of operating member for such a cam is connected to the heel partof the tree, so that the tilting upward of the `heel part, as would naturally be done in inserting the tree in the shoe, operates `the cam to collapse the forepart. l n It is an4 object of this invention to provide a simple, eiiicient and economical shoe tree having an expansible forepartfand an extensible rear section whereby one tree may be used in of different sizes and shapes.` l l In accordance with this object, a feature of the invention residesin improved mechanism for controlling the expansion of the forepart sections panding springs employed. This, aslillustrated,

comprises a plate adapted to be received in ref.` cesses inadjacent faces of the forepart sections, the uplatelbeing slotted to cooperate with pins in said sectionsto limit the expandingmovement a`.ndhayir1gl` tubular endportions `which enclose To obviate this diliculty, a cam is` I0, and 22, 24 in the section l2; shoes longitudinally thereof. e

,Another feature `will be recognized in an improved `cam arrangement for `collapsing the `forepart sections when it is desired to insert the tree intoa shoe. l

This l cam, positioned between the rearmost spring and the heel end of the forepart, operates to draw the forepart sections together and, in

its illustrated form, consists of a tubular cam which is received inrecesses in the adjacent faces `of the forepart sections and has two pairs of slots cooperating with a pair of pins in said sections. A connection to the heel part, com` prising a ilat plate positioned in a vertical plane to avoid interference with the forepart sections,

is utilized as a cam operating member.

rol

With the above and other objects in view, the

invention will be described with reference to the accompanying drawing and will be pointed out in the appended claims.

yIn the drawing, f l Fig. 1 isa plan View, partly the relationship of the parts when the tree `is fully extended;

Fig. 2 is a fragmentary perspective view illus trating the cam and showing the connection be` tween it andone of the sections of the forepart,

and f Fig. 3 is aside elevation showing the relative positions assumed by the forepart and the heel` portion of the tree when the sections of theffore` in section, showing partare drawn together `preparatory to inserting them into a shoe.

Referringto the drawing,the tree comprises` of the sections Hl, I2 is" limited by a plate 2B which is seated in a sawkerf or slot 28 formed in the `.sections I0, l2`.` The plate 26` is loosely connected tothe` sections by pin-and-slot connectionslconsisting of pins 3B, 32 inthe sections l |0512 which pass through elongated slots 34, 36 in theplate 26. lIt is to be noted that the slots 34,-36 are somewhat wider than the diameter of thepins 3B, 32 `to permit a limited angular movement of l the sections relative togeach other so that they may adapt themselves to `the shapes of different shoes. `The ends of the plate26 are formedinto tubular portions 38, lill which enclose theyportion of `the springs I4, lthat would noritt The spreading springs I 4,

tively to one another and without any catching ,i

of the springs. The

tubular portions

38, 40 are made slightly larger than the diameter of the I 6 so that the springs may move freely in the tubular portions. Also, the tubular` yportions are somewhat smaller than the diameter of the recesses I8, 20, 22 andy 24 so as to allow for free relative movement between the sections and the plate 26.

When the tree is prepared for insertion into a shoe the sections I0, I2 are drawn together against the action of the springs I4, I6 by a tubular cam member 42 which is located rearwardly of the tree from the springs I4, I6 and the plate 26 and has its end portions seated in

alined recesses

44, 46 in the adjoining faces of the sections Y il), I2. As is best shown in Fig. 2,'the cam 42 has a set of

cam slots

48, 50 formed at each end thereof, each set of cam slots consisting of an upperv and lower cam slot (Fig. 2) which is disposed within one of` the recesses 44, 4S. Passing throughv the cam slots 48, 5U are

pins

52, 54 which are mounted in the sections Ill, l 2.

The cam 42 is rotated to draw the sections Il), I2 together by a bar 56 which is connected at one end to the mid-portion of the cam 42 and at the other end to the heel piece 68 oi the tree. When this bar is moved in a height-wise direction with respect to the forepart to the position shown in Fig. 3, the cam 42 is rotated so that the

pins

52, 54 are moved into the parallel sections 58, Bll of the

cam slots

48, 54 thus causing the sections I0, I2 to be moved together and held while theforepart is being inserted into a shoe. After the forepart has been inserted into a shoe, the bar 56 and heel piece 68 are moved downwardly to bring a

wide portion

52, 64 of the cam slots 48, 5D into register with the

pins

52, 54 so that the sections of the forepart maybe pressed apart by springs I4, IS to fill the shoe in which the tree is placed. It is to be noted that the wide portions 62, E4 of the cam slots extend outwardly beyond the

pins

52, 54 so that they do not act to limit the outward; movement of the sections I0, I2 under the urging of the springs I4, I6, this being the function of the pins 30, 32. With this arrangement .the

pins

52, 54 will not act as a limiting means to the relative angular movement of the sections II), I2.

The rearwardly extending portion of the bar 56 is slidably received in a recess 66 in the heel piece 68 and its withdrawal from this recess is prevented by a struck-out nger 'Ill which engages a plate 'l2 in the heel piece 68. 'Ihe heel piece 68 is urged rearwardly away from the forepart by a spring I4 which is interposed between the end of the bar 56 and a wall of the recess 66 thereby. to ll the shoe and extend it lengthwise. v
