Application filed April 18, 1922. Serial No. 555.318.

To all whom fit may concern:

Be it known that l, Annan-nar Dumma,

a subject of the United Kingdom of Great Britain and lreland, resicii o; at Stoneham, in the county of Middle/ser: and State of li/lassachusetts, have invented a new and useful improvement in Shoe Formers.V of Which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to a shoe former, adapted to be placed in the shoe after the last has been removed, in order to maintain the shoe in its proper form during the final operations of manufacture.

In shoe manufacturing, after the last has been pulled from thel shoe, the latter is subjected to a number of final operations such as monogrannning, Cleaning, the insertion of sock lining, treeing, repairing, dressing, brushing, etc., Which operations are usually carried on in the treeing and paclring room. These various operations have a tendency to change the form given to the shoe by the last and to destroy its correct-lines and fitting qualities. For instance, the natural reaction of the stock under the finishing processes, especially in a thin-soled shoe. frequently causes the toe of the shoe to turn upivardly, Which result is aggravated by the monogramming and cleaning processes. This spoils the shape and appearance of the shoe. Again, it frequently happens in shoes made from soft leathers that small ivrinlrles appear in the leather, oWing to the fact that it is not supported over a firm Substance or held under tension during the final processes. lt is customary to shrink out these ivrinlrles With a hot iron Which, however, shrinks the leather Without affecting the lining, and thereby causes an objectionable fullness in the latter. In short, these various final processes have the general efiect of distort-V ing the shoe and destroying the correct form given it by the last, so that, When the shoe is packed, its sides are spread apart more or less, giving it an appearance of having been Worn and detracting from its 'attractivenessg to suit varying conditions.

Other objects of the invention Will be more specifically described and pointed out hereinafter.

a former invention contemplates adapted for insertion in a shoe and provided With expanding means, Whereby pressure is exerted longitudinally upon the front and rear portions of the shoe to straighten it and to cause the sides to close in.

Preferably the pressure is e-Xerted in a plane Which passes longitudinally and centrally through the shoe, and is approximately perpendlcular to the sole.

lin its preferred form my invention contemplates a former comprising tivo over-lapping members connected together, but capable of relative sliding movement. one upon the other, With expanding means between; one of said members being adapted to engage the rear portion of the shoe on a central line from the sole to the top of the upper, and the other of said members being adapted to engage the toe and the front of the vamp or upper of the shoe on a central line.

One of the imp rtant features of my invention resides in providing expanding means which is resilient and adjustable, ivhereby the former may be easily adapted to different sizes and kinds of shoes to secure the best results under difierent and varying conditions.

lt is important that the shoe be lrept under the proper tension during the final processes of manufacturing to avoid stretching the leather or Warping the shoe; and since the amount of tension Will vary Within certain limits to conform to varying conditions of stock, it is essential to the securing of satisfactory results thaiJ the expanding means be resilient and adjustable. Furthermore, the provision of such means permits the former to be inserted in and removed from the shoe Without injury thereto, and Without changing or modifying the correctv lines given it by the former.

in the draw'ings illustrating the preferred form'of my mvention, Figure 1 is a side o'n of a formerl constructed and opereleva with my inventi with ioin adoption ment of n intention., there is shown a Which members i :l to

The attachment sho in 9 comprises a member 52, ef-:tz -3 'ling npwarclly :ind then clownword y, sno having :i loop 54 Which acts as a spring,

The operati n of my device is extremely simple and is as fo loWs: The block 26 is iir-:cd in position, clopenclent upon the size of the shoe in Which the former is to be plaeedE Which location Will secure a normal pressure upon the shoe in :i longitnclinal (lirect-ion. in order to place the former in the shoe, the finger piece 82 is pnlled back, com- -pressing1 the spring 24, and While in this poi 1,4sa745 its forward position, yet permitting it to retract to a certain extent to conform to the .longitudinal dimension of the shoe and the resistance oifered by the upper portion of rllhe position of the former withthe vamp. in the shoe is shown in Figure 1.

The effect of the former upon the shoe is that of exciting a stretching pressure on both the front and back of the shoe longitudinally, which naturally causes the sides of the shoe to straighten and close inwardly toward each other, thereby narrowing the shoe. rllhe former is inserted in the shoe immediately after it is removed from the last, and is maintained there-in until thel shoe is ready to be packed. As a result of the shoe being under tension during the finishing operations, the necessity of ironing, with the consequent shrinlring and se-a-rng of the pores of the leather, is either entirely obvia-t-ed or greatly reduced. At the same time, the application of the dressing to the shoe while the leather is under the tension of the former, tills the pores of the skin, and after' the former is removed the dressing serves to retain the shoe in its proper form.

To remove the former from the shoe, the member 12 is retracted through the medium of the finger piece 32, which shortens the former and relieves t-he pressure of the spring 50 upon the vamp member 40, whereupon the former may be easily removed from the shoe without Strain, and without disturbing the correct lines of the shoe.

The provision of graduations denot-ing the proper position of the block 26 for each size of shoe is of importance, since it permits the former to be properly adjusted before insortion in the shoe, and thus saves the time which otherwise would be wasted in various experimental adjustments designed to attain the desired pressure.

It will be observed that the adjustable feature of my device gives it a wide range of adaptability, which is a very material consideration VWhen the initial expense of securing an adequate number of devices for a manufacturing business is involved. At the same time, the fact that the device may be made of wire conduces to a low cost, and enables it tobe manufact-ured and sold at a price which will j ustify its use in large quantities.

The advantages attained by the use of my device in the manufacturing and sale of shoes are manifold. It facilitates the handling of the shoe during the final processes; it insures correct and attractive lines in the shoe when presented for sale, and it improres the fitting qualities. The shoe is given long and narrow lines, andthe sides of the shoe hug and fit closely the sides of the foot of the wearer.

It is to be understood thatmy invention is not to be limited to the particular embodiment heroin shown and described, as it may be exemplified in various other forms of construction without departing therefrom, all within the scope of the following claims.
