Patented Dec. 17, 1929 CLARENCE H. YOUNG, OF BOSTON, MASSACHUSETTS SHOE STICK Application filed February 28, 1928. Serial No. 257,720.

This invention which relates to shoe sticks and has among its objects the provision of improved means for holding the last engaging members, will be best understood from the following description when read in the light of the accompanying drawing of a specific embodiment of the invention, while the scope of the invention will be more particularly pointed out in the appended claims.

In the drawing Fig. 1 is a side elevation, with parts broken away, of a shoe stick constructed according to the invention;

Fig. 2 is a plan according to Fig. 1;

Fig. 3 is a plan on an enlarged scale as compared with Figs. 1 and 2 of a fragment of a shoe stick with parts broken away; and

Fig. 4 is a section on an enlarged scale on the line 44 of Fig. 1.

The shoe stick illustrated by the drawing comprises a pair of elongated, relatively wide and thin metal strips 1 and 2 secured to each other in spaced parallel relation by rivets 3. In practice with this example of the invention the cross-sectional shape and full size of these strips may be as indicated in Fig. 4, while the length of the strips may be about four feet.

As shown spacers 4 are provided formed of fiat strips of metal bent at their ends to provide eyes 5 through which the rivets 3 extend, the spacers being coextensive in length with the width ofthe sheet.

As illustrated the strips 1 and 2 at their ends are bent toward each other at 6 to provide contacting portions 7 presenting thickened end portions for the stick for resting upon a support. For strengthening the ends one of the spacers 4 conveniently is located close to the bent portions 6.

As shown the stick is provided with pairs of spaced pins 8 which in practice enter pairs of holes in the lasts so as to secure them to the stick. As illustrated the lower strip 1 is perforated, while the ends of the pins are formed with reduced diameter portions 9 which enter said perforations and are riveted over as at 10 to draw the shoulder portions 11 of -the pins against the strip and secure the pins to the strip. The upper strip 2 is provided with perforations 12 through which the pins extend, the Walls of the perforations engaging the pins. 1

it has been found in practice that the lasts, especially heavy lasts such as iron lasts used in connection with fabrication of rubber footwear, tend to bend or break ofi the pins where they are riveted or otherwise secured at their ends to their support. By providing the upper strip 2 which engages with the pins intermediate their length the pins are firmly braced against bending relative to the lower strip. The presence of. the upper strip 2 makes it possible to use a light weight lower strip 1, making possible the product-ion of a much lighter shoe stick than it the upper strip were absent and the lower. strip were made heavy enough to take the load, it being understood in this respect that the two strips are so disposed relative to each other and sosecured to each other as to provide a beam with a minimum of cross-sectional area, yet with a maximum of so-called sectional moment of inertia.

It willbe understood that other shapes may be substituted for the strip 1 and that wide deviationsmay be made from the embodiment of the invention herein disclosed without departing from the spirt of the invention.

I claim: I

1. A shoe stick having, in combination, an elongated, relatively wide and thin metal strip, pins for engaging lasts secured at one of their ends to said strip, a similarstrip having perforations closely fitting said pins at points intermediate their length, and means independent of said pins securing said strips to each other in rigid spaced relation, whereby to form a relatively light weight and rigid beam carrying said pins and supporting them against bending at their ends relative to the first mentioned strip. I t I 2. A shoe sti k for supporting a plurality of lasts comprising'a beam having an elongated, relatively thinpart to which are secured the ends of a plurality of projecting last pins, and a second relatively thin part spaced from the first mentioned part and having a plurality of perforations fitting said pins at pointsintermediate their length.

3. A shoe stick for supporting a plurality oflasts comprising a beam having an elongated, relatively thin part to which are socured the ends of a plurality of projecting last pins, and a second relatively thin part spaced from the first mentioned part and having a plurality of perforations fitting said pins at points intermediate their length, said relatively thin parts rigidly secured to each other at spaced points by means independent of said pins.

4. A shoe stick for supporting a plurality of lasts comprising an elongated member; a plurality of pairs of last pins distributed longitudinally of said member; the pins of each pair of pins arranged, relatively to each other, transversely of said member; each pin secured at one end thereof to said member; and means for bracing said pins comprising a second member having perforations through which said pins ext nd, said member being spaced from said first mentioned member. I

5. A shoe stick for supporting a plurality of lasts comprising an elongated member;

a plurality of pairs of last pins distributed longitudinally of said member; the pins of each pair of pins arranged, relatively to each other, transversely of said member; each pin secured at one end thereof to said member;

elongated part formed with perforations,

pins having end portions of reduced diameter providing shoulders, said end portions extending through said perforations and riveted for securing said pins to said part with said shoulders in contact therewith, and means for bracing said pins against {bending relative to said part comprising a member rigidly secured to said part and engag- 1 ing" said pins intermediate their lengths.

8. A shoe stick having, in combinatioma pair of elongated, relatively wide and thin metal strips, a plurality of spacers between said stri ssaid spacers each compri ing a strip of metal bent at oppositeends thereof to form eyes, opposite edg s of said pacers contacting with opposed sides of said strips throughout substantially the entire width of said stri s, rivets pa sing through said eye and through aligned perforations in said strips}, plurality of pairs of spaced pins carried by said elongated strips, the pins of each pair of pins being situated adjacent opposite edges of said elongated strips and having one of their ends shouldered and riveted to the lower strip and extending through a closely fitting perforation in the other strip, said elongated strips at their end portions being bent toward each other into contact to provide thickened support engaging parts, a spacer being situated adjacent each of said parts.

In testimony whereof, I have signed my name to this specification.

CLARENCE H. YOUNG.
