SHOE STRETCHER.

Application'led .Tune 16, 1921, Serial No. 478,101. Renewed August 8, 1922." Serialill'o.` 580,546.

To all fuif/2.0m 'it 'muy concer/t.'

Be it known that l, I-lnirnYVi-rrnus, a citiren of the United States, and a resident of Bisbee, in the county of Cochise and vState of Arizona, have invented certain new and useful mprovements in Shoe Stretchers, of which the following is a specification.

This invention relates to stretching'devices especially adapted for use in shoes.

Au important object of this invention is to provide a shoe stretcher having novel means whereby either the forwarder rear end of the stretcher body may be readily spread for stretching either the toe or intermediate portion of a shoe.

A further object of the invention is to provide a shoe stretcher comprising means whereby the shoe may be stretched longitudinally.

Other objects and advantages of the invention will be apparent during the course of the following'description.

In the accompanying drawing:

Figure 1 is a perspective of the improved shoe stretcher.

Figure 2 is a central vertical longitudinal sectional view through the same.

Figure 3 is a group perspective of a' spreading device embodied in the invention.

Figure i is a group perspective of a hinge embodied in the invention.

Figure 5 is a perspective of a hinge pin adapted for use in connection with the hinge illustrated in Figure 4.

Figure G is a detailed horizontal sectional view through the improved stretcher, the view illustrating the application of the spreading means for the movable sections.

Figure 7 is a perspective of a cross head forming` a part of the invention.

lu the drawing the numerals 5 designate a pair of similarly formed coacting sections h aving their opposed sides formed with longitudinally curved grooves 6 defining channel within which a spreading member lgenerally designated by the numeral 8 is slidably arranged. With reference to Figure 6 it will be observed that the intermediate portions of the grooves 6 have their bottom walls formed with depressions or notches 10 which receive the stretching-block 8 whereby the sections 5 may flatly contact with each other. wWhen the spreading block 8 is positioned Within the depressions or vnotches 10 it is in what might be termed a neutral position since neither the forward nor the rear end of the device is spread. However, the grooves 6 gradually decrease in depth towards the ends of the sections 5 from the depressions'. 10 so that as the spreading block 8 is moved either forwardly orrearwardly the sections 5 will be spread. 'The spreading member 8 comprises sections 12 and 13, the section 13 being provided with ears 14 extended on opposite sides of the section 12 and pivotally connected to the same by means of a pin 15. By reason of this construction the spreading block generally designated by the numeral 8 is permitted to partake of free sliding mover'nent in the channel formed by the opposed grooves 6 which are curved longitudinally.. The forward endv of the section 12 is rounded as indicated at 16 and is received within a transversely curved groove in the rear portion of the section 13.

The means for movingthe adjusting block 8 longitudinally of the sections 5 includes a feed screw 18 having its forward end v formed with a reduced neck 2O terminating in an enlarged head 21 preferably of spheri-V cal formation. The head 21 is adapted to enter an opening in the section 12 by means of a transverse slot 24 extending out through one side of the section`12 and having screw threads whereby a retaining screw 25 may be threaded into the section for holding the head 21 in position.

A cross head 28 is arranged in registering recesses 3() in the opposite sidesl of the sections 5 and is provided' with a transverse interiorly screw threaded opening 31 for the reception of the feed or adjusting screw 18. Pins 32 extend from the ends of the cross head and are freely received in openings 34 extended out through the sides of the sections 5. When the feed screw 18 is rotated the same will be 'moved longitudinally for imparting a corresponding movement to the spreading` block 8 for separat, ing either the forward or rear portions of the device.

The rear portion of the feed screw is provided with a handle'85 by means of which the'feed screw may be manually rotated for adjusting the width of the device. When it is desired to stretch the shoe longitudinally a heel section 36 having a longitudinally slotted arm 37 may be connected to the feed screw by means of a nut 38 with heads 46 which constitute stop elements to limit the sliding movement of the sections with relation to each other. The sections 5 may also lpartake of a hinged movement withTelation vto `each other since -the squared hinge' pin 42 .is lformed of a pair of-sections pivotally connected as indicated at 48. The pivotal .connection 48 of the hinge pin `42 is between ythe barrels 41 and permits the `ltorward portions of the spreader sections 5 to be swung outwardly whenthe member 8 is advanced.

The `toe of the shoe may be slightly ele` vated byA .means of a toe ,plate 50 having a shank 51 -which is slidable between the secf tions 5 andfwhich is provided witha base plate y52 slidable in the grooves 6.5

As illustrated in Figure 3, the rear portion of the base vplate 52 is formed with rearwardly `directed apertured Iears 54 adapted to rbe arranged'on opposite sides of and pivotallyconnected to the Jforward portion of thesection 12 ofthe spreading member l8 so that the longitudinal movement of the screw 18 will result in the sliding movementof the toev plate which may be curved transversely or otherwise formed. In the use of the improved stretcher the toev plate 50 is applied to the section 12 only when it is desired to force the toe of the shoe upwardly. e

Having thus described the invention what Ici-aim as new and' desire to secure-.by Letters Patent is f 1. A shoe stretcher comprising a pair of sections, hinge plates secured to the rear ends oi said sections and having aligned barrels, a hinge pinpassed through said barrels and inclusive of pivotally connected sections whereby the sections may partalre oi? a hinge movement with relation to each other, and a spreading` member arranged be,- tween said sections.

2. A shoe stretcher comprising a pair of sections, hinged plates secured to the rear ends ot said sections and having aligned barrels, a hinged pin passed through said barrels and inclusivev of pivotally connected sections vwhereby the sections may partake oi' a hinged movement with relation to each other, a; spreading member arranged between said sections, and a eeding'device associated with said spreading member.

3. A shoe stretcher comprising sections, hinge plates secured to the rear ends of the sections and having aligned'barrels, and a hinge pin passed through said barrels and inclusive ot pivotally connected sections whereby vthe sections may partake of a hinge movement. i

4. A shoe stretcher comprising sections, hinge plates secured to thesections and having aligned hinge barrels, and a square hinge pin passed through said barrels and being of a greater length than the space between the ends of said'barrels whereby the sections may partake ot' vsliding movement with relation-to each other, said hinge kpin being composed o1 a pair of pivotally connected sections.

5. A shoe stretcher comprising sections, hinge plates securedv to the sections and having aligned hinge barrels, a square hinge pin passed through said barrels and being of a greater length than they space between the ends of said barrels whereby the sections may ypartake. of sliding movement with relation to each other, said hingev pin Vbeing composed of 'a pair of pivotally connected sections, and means to separate said rst named sections.
