. 7 Claims.

This invention relates to devices for stretching boots and shoes and its object is to render and 1 Figure 2 is a section on line 2-2 of Figure 3 'showing the'inner fiat surface with expansion sings and hand rod carrier and metal tube axis assembly.

engage the recessed converging wedge surfaces ll, l2, l3 and It, respectively which'form openings as indicated, which openings are formed by slotting or mortising' into the respective-inner flat surface of the wooden members I and 2. Rotation ofrod 8 causes wooden members I and'2 to separate and move outwardly, parallel to each other, along the metal tube axis 5, thus creating a uniform stretching operation.

The wooden members i and 2 are brought back to a closed position and normally held in place by a coil spring I placed inside of the metal tube axis 5, metal disks or plugs'9 and being attached to each end of the spring and countersunk in the outer edges of the wooden members to thereby normally pull Said wooden members i and 2' together.

The invention is not to be understood as re claim as new and desire to secure by Letters rotatably mounted on said rod in spaced apart position to move in said spaced apart recesses respectively, the rotation of said rod in one direction being adapted to move said expansion 'slugs forwardly to separate said members.

3. In a shoe stretcher, or the like, a pair of wooden members movable with respect to each other and having a substantially flat side adjacent each other, each said member having a forwardly and inwardly converging recess at its rear 15 Figure 3 is a plan view, partly broken away.- Patent is: 15 Figure a c n l V On l of 1.

4. In a shoe stretcher, two co-incident wooden members adapted to form, when combined, a foot portion, said members having fiat sides opposed to eachother and each member having a pair of spaced apart recesses in each thereof converging towardthe opposite corresponding recesses respectively in the other member," said recesses opening on 'said'flat side, said members having a transverse aperture therethrough; a guide tube extending through said aperture; a spring in said guide tube and connected to said members respectively to exert a pulling together stress thereon; a bearing member mounted adjacent said guide tube and normally within the forward coincident recesses; a manually actuable rod threaded in said bearing member; a pair of spaced apart wedge-shaped slugs mounted on said rod, each of said slugs converging towards its forward end and having an aperture therethrough; a thrust collar secured on said rod in each of said apertures of said slugs, the rotation of said rod being adapted to thrust said slugs longitudinally and either forwardly or rearward ly, the forward movement of said slugs being adapted to separate said woodenmembers.

5. In a shoe stretcher comprising two co-incident members having a transverse aperture therethrough and each thereof having a pair of spaced .apart recesses, therecesses of one of said members converging toward the'correspo-nding opposite recesses in the other of said members; a guide tube in said transverse aperture; a spring having its opposite ends connected to said "members respectively; a threaded bearing-member; a manually actuable rod having a threaded portion vthreaclingly engaging said bearing member; a forward wedge-shaped slug movable in said forward recesses, said slug having an aperture therein and being rotatably secured with respect to the forward end of said rod; an expansion slug rotatably secured with respect to said rod and adapted to move in the rearward recess of said members; rotation of said rod being.

adapted to move said slugs longitudinally.

6. In a shoe stretcher, a pair of members having a metal tube for an axis, a transverse metal tube; a coil spring in said tube connecting said members; a metal disk attached to each end of' apart recesses respectively, each of said slugs having an aperture therethrough, a thrust collar secured on said rod and rotatable in said aperture of each said expansion slug, the rotation of said rod in one direction being adapted to move said expansion slugs forwardly to separate said members.

'7. In a shoe stretcher comprising a pair of wooden members, each having a flat side opposite the other and each having a pair of spaced apart recesses opening on said flat side, and having a transverse aperture therein the recesses in one member converging toward the corresponding recesses in the other member; a tube mounted in said aperture; 'a spring in said tube and connecting said members and adapted to pull said members together; a, bearing membermounted between said separable members; a rod having a threaded portion threadingly engaging said bearing member; a pair of wedge-shaped expansion slugs movable in said recesses respectively, each of said slugs having a substantially flat upper and lower surface and forwardly converging'opposite sides and having a vertically extending aperture therethrough, said rod extending longitudinally through said spaced apart expansion slugs; and a thrustcollar secured about said rod and rotatable in said vertical aperture ofeach said expansion slugs, the rotation of said rod being adapted to separate said members.
