` SHOE LENGTHENING DEVICE Filed NOV. 24, 1934 2 Sheets-Sheet 2 HMI H Patented June 30, 1936 @ETE STATES PATENT OFFICE Claims.

rIhe invention relates to a novel and improved device for stretching shoes. or the like, and more particularly to a device adapted for stretching shoes lengthwise, whereby the length of the same may be increased.

Devices heretofore commonly employed for this purpose include eXpansible means disposed within the shoe, which means were then acted upon to stretch the shoe, said means acting against the 1o forward end of the shoe and the heel portion thereof. The result of this form of stretching was not a lengthening of the shoe, but a stretching of the side upper edges thereof causing in many instances a breaking along said edges with i5 resultant bulging at the side edges when the shoe is again placed on the foot of the wearer.

It is an object of this invention to overcome the above diiculties by the provision of a device particularly adapted for lengthening shoes, the

stretching operation of which will be accomplished without the exertion of any pressure against the heel portion of the shoe.

Another object of the invention is to provide a device of the character described adapted for disposition in the forward end of a shoe for stretching the same lengthwise, including a yoke member disposed on the outer forward end of the shoe and against which the reaction of the stretching operation takes place.

Another object of the invention is to provide a device of the character described including an adjustable member disposed in the forward end of the shoe, and means for forcing said adjustable member against said forward end of the shoe and a yoke disposed on the outer forward end of the shoe cooperating with said rst mentioned member for permitting a lengthening of the shoe without the exertion of pressure on the rear portion of said shoe.

A further object of this invention is to provide a device of the character described particularly adapted for lengthening shoes which may be simple in construction, assembly and operation, and which may be produced along lines convenient for cheap manufacture, but which will at the same time be highly efficient for carrying out the purposes for which it is designed.

With the foregoing and other objects in View, which will appear as the description proceeds, the

invention consists in certain novel features of construction, arrangement and combinationv of parts, hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it

being understood that various changes in the form, proportion, size and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention,

For the purpose of facilitating an understand- 5 ing of my invention, I have illustrated in the accompanying drawings a preferred embodiment thereof, from an inspection of which when considered in connection with the following description, my invention, its mode of construction, as- 10 sembly and operation, and many of its advantages should be readily understood and appreciated.

Stat/ed generally, the invention comprises a 35 device which is particularly adapted for stretching the forward portions of shoes or the like without stretching the side edges thereof, this being accomplished by the elimination of any pressure during the str-etching operation on the heel por- 40V tion of the shoe. In the embodiments illustrated, the invention includes a member l0 made of suitable metal, said member being provided with a sole portion Il which is shaped substantially in the form to adapt it for disposition on the inner 45 face of the sole of a shoe, said member I0 being provided with a rearwardly inclined portion l2. The side portions of said member l0 are bent upwardly, as shown at I3, and the free edges of said upwardly extending portions are then bent 50 inwardly as shown at I4 for a purpose to be presently more fully described. Similarly the inclined portion l2 has the side edges thereof bent upwardly and then inwardly to form a socket I5 for a purpose to be presently more fully described. 55

` faceV of which is formed an elongated slot 2D, said slot being open at its free end and is in communication'with a guide recess 2l Yprovided in the eX-Y tension I9. Y

TheV rearwardly extending socket I5 of the member lil is adapted for receiving therein `an ex-` tension 22 of a substantially vertically disposed yoke member 23, said member being shaped substantially as shown Vin the drawings and is providedY with the top wall 24 through which is threaded a screw member 25, on the lower Yend of which is mounted the member 25, said member being adapted for disposition within the recess or guide 2E, as shown Fig. 6, with the body of the screw member 25Yetending through the slot 20. The member 26 is freely rotatable on a reduced portion on the lower edge of the screw member 25 to permit free rotation of the screw 25, which rotation wiliimpart the Ydesired movement to the member 6 for lowering or raising the same aboutY its pivots |l. As shown in Fig. 6, the member 26 wili slide within its guide slot 2l Vduring the last mentioned operation.

V suitable` handle 2'! is provided at the upper portion of the screw 25 for facilitating in the Vactuating of the sam-e.; Byreason of the means just described the member I6 may be adjusted within the shoe to the desired position' relative Yto the member it@ Pivotally mounted between the side walls of the member 23 adjacent-the lower portion thereof, is a V,block member 28, said block member being pivotally secured to said side walls of the member 23 by means of therivets 29, and said block member is provided with a threaded opening extendingV at an inclined Yangle therethrough,

Ywithin whichY opening is received in threaded en- Y gagement the screw member 3B, said screw member extending through an enlarged opening 3| in the rear wall of the member23 and having its lower portion provided withY a semi-cylindrical head 32 rigidly secured thereto for a purpose to be Vpresently more fully described. 'Ihe upper free end of the screw member 3i! is provided with a screw handle 33 for facilitating the actuation forth movement relative to the forward edges of 65A themembers ID and i6; Adjacent the rear portion ofthe Ymember 34 is provided a semi-cylindrical'recess 36 within which is adapted to be re vided with a screw threaded studV 31 upon which is threaded a toe piece 38 made of suitabie ma-A terial, which toe pieces may be madeeof various sizes and detachably secured to the member 34 in the manner illustrated.

By reason ofrthe'mechanism sc far described, 5

it will be readily apparent that the member I3 Ymay be adjusted by the actuation of the screw member 25 to the desired position relative to the member lil, and that the actuation of the memthe screw member 30 in the desired rotation. This mechanismrmay be vdisposed within the forward portion of a shoe and the members 25 and 3D actuated to move the same in proper position within operation. V

' The following mechanism is provided for taking up the rearwardrpressure exerted on the member 34 by means of the screw 30. This mechanism includes a cross piece .3S rigidly secured to the rear wall of the member 23 at a point immediately above the screw member 3S.V Y Y Y A suitable yokeV 43 of substantially inverted U-shaped formation is provided, the lowermost portions of saidV arms of the yoke 4@ being g threaded as shown at 4|, said portions being adapted for receiving Ytherein a cross piate 42, the major portion of which is covered with a suitable covering 43 of rubber or leather. The cross Vber 34 may be accomplished by the rotation of 10 Ythe shoe prior to starting the actual lengthening 15 Y plate is secured in place on the yoke mem-ber4r30 by means of the wing nuts 44 threaded on the threaded portions 4l' of the legs of the yoke 40.

Rigidly secured to the yoke are the rearwardly extending Yside arms 45 to the forwardV ends of which are-pivotally secured, as shown'at 35 Vity of notches 48, which'notches are adapted to engage the crossA bar 39 shown in Figs. 1 and 2 of they drawings. By Yproviding a plurality of 4 said notches 48 the position of the yoke 40 with reference to the member23 may be readily adjusted. A suitable flexible covering 49 may also be provided for the top portion ofthe yoke 40. to prevent marring or injury to` the shoe when theV 4 device is in operative position thereon.

In operation, the device with theyoke 40 removed therefrom is disposed within the shoe to be operated upon, a toe pieceY 38 ofV suitable size having rst been selected and attached to the 5 member 34. The'screw member 25 is then actuatedto bring the vamp piece or memberY I6 into proper position with reference to the vamp of the shoe.

The yoke 40 is then placed in position on the 5 outer portion of the shoe, a"s vshown in Fig. l, and the wing nuts 44 actuated to bring the crc-ss piece -i3 to bea-r against the sole portionV of theshoe. The arms 4l 'are then swung into engagement with the cross bar 39, one of said notches 48 on the underside of said arms 47 engaging said cross bar. The lengtheningV operation may now be accomplished byaotuating the screw member-30 by means of the'handle 33, which actuation will portion of the shoe, the rear pressure being taken up by the yoke 40 through the arms 41 and cross. bar 39. It will be noted that the yoke will bear against the vamp portion i5 of the device, there-` by clearly eliminating any stretching or the exertion ofpressure on the side edges of the shoef From Ythe above it should be readily apparent' that I have provided a device which will be lhighly efficient for lengthening a shoe while at the same time preventing stretching or injury to the 75 Y force the toe piece 38 forwardly into the forwardV G5 side edges thereof. In assembled position, the device will conform to the inner configuration of the vamp portion of thev shoe with the toe section disposed in position for longitudinal movement only, By providing Vthe guide anges I4 upon which the toe section is slidably mounted, it will be noted that the said toe section will move in a substantially horizontal plane when urged forwardly bythe actuation ofthe screw member 30.

It will also be noted that by reason of the adjustable engagement of the toe piece 38 with the sectional member 34, toe pieces of varying sizes may bey employed. The adjustability of the vamp portion Ha' will-permit the use of the device on shoesof varying sizes and varying styles. Similarly the provision of the plurality of notches on the arms 41 will enable the device to be adjusted to accommodate it for use upon shoes of various sizes and lengths.

It is believed that my invention, Aits mode of construction, assembly and operation, and many of its advantages should be readily understood from the foregoing without further description, and should also be manifest that while a preferred embodiment of the invention has been shown and described for illustrative purposes, the structural details are, nevertheless, capable of wide variation within the purview of my invention as defined in the appended claims.
