Description
Se t. 14, 1937. F.4N. LA CHAPELLE 2,092,807
Patentecl Sept. 14, 1937 FASTENING Fred N. La Chapelle, Beverly, Mass., assgnor to United Shoe Machnery Oorporation, Paterson, N. J a corporation of New Jersey Application July 29, 1936, Serial No. 93,253
3 Claims.
This invention re1ates to mprovements in fastem'ngs and is heren llustrated as emboded in staples formed from twisted paper impregnated with glue. V
Staples formed. of felted fibrous materal, such as paper, of the type dsclosed in United States Letters Patent No. 1,957,216, granted May 1, 1934, upon an application filed in the name of Fred N. La. Chapelle have been used successfully a.s effectve fastenngs for securing together work peces of leather or other materials, particularly in the manufacture of boots and shoes. I-Iowever, under certain condtons difficulty has been experienced in mantainng the staples permanently in positon. Instances of this have occurred, for example, in securng an insole or middle sole to the upper of a stitchdown shoe particularly where the sole is of flmsy material such as soft paper which does not provide sufficient anchorage for the staples, or where the sole is coated Wth wax or other stfi"ening material in which case the glue on the staple does not grip as well as Wou1d otherwise be the case. These dificulties are aggravated in cases where, for the sake of economy, the shoe manufacturer allows only a small lastng margin on the upper with the result that the upper has to be stretched over the last under great tension. This results in applying an unusual amount of stress to the staples which secure the marginal portion of the upper to the sole and frequently results in breaking the legs of the staple after the glue has set or in pulling the staple loose from the sole.
In view of the foregong, t is an object of the present invention to provide an improved. fastening by the use of which the dificultes above mentioned will be overcome. llustrated, I have provided a. fastenng having an outer layer of felted fibrous material impregnated. With stiiem'ng material and having a reinforcing metal core. Preferably and. as shown, the outer layei* is composed of twisted paper impregnated. With glue and the core consists of wire made of soft iron or other soft metal.
Staples constructed as above oufilined are advantageous in that when they are drven into the parts which they are to secure together and. the
1egs of the staples are defiected the wire core W11 tend to hold. the staple in position and resist forces which mght tend to pull the staple out of the material or to break the legs of the staple. Furthermore, the core, beng of soft metal, will not, interfere with subsequent stitching operations. That is, if the needle should engage the Accordingly, and as core of the staple the nedle will not be deflected or broken.
It is to be understood thai: whle the invention is illustrated herein in connection With a staple construction the inventon is not solimited. since t is apparent thai: other types of fastenngs such as, for example, pegs, could be formed of fastening material of the type above described ami provided with a wire reinforcng core.
These and other features of the invention are disclosed in the accompanying drawng, described in the following detailed specification, and pointed out in the claims.
The drawing is a diagrammatc view on a muc enlared scale in which-- 7 7 Fig. 1 illustrates a side view partly in section f a staple constructed in accordance with one embodiment of the invention;
Fig. 2 illustrates a. cross secton through one leg of the staple; and
Fig. 3 is a side view of the fastening materia] from which the staple is made.
The staple illustrated in Fig. 1 corfip'risea cross bar IO and two depending legs |2, the shape of the staple' being substantially that of ann-.
verted U. The staple is made from a leng'th of fastening material, Fig. 3, comprisng a metallic core I4, preferably of soft iron wire, aboi1t which is twisted an outer layer of felted. fabr c materal |6 such as paper impregnated. With glue during the twisting operation. The m'aterial may be about ,040 of an nch in diameter Wth an iron wire core about .009 of aninch in diarheteralthough other dimensions may also be used. The 7 manufacture of the fastening materal can be conveniently accomplshedby use of a:machine such as that disclosed. in United States Letters Patent No. 1,837,433, granted. December 22, 19317 is c0vered b'eing moistened so that'thelegs of' the staple Wi1l gripthe material after the glue s V 'set, and the staple legs are de'flected toward the surface of the work pece through which they pass With the result that the wire reinforing cor 01 the United States is:
1. A fastenng comprising a core of wire covered throughout ts entre length with twisted felted fibrous material sized With stifienng materal.
2. A staple of felted fibrous material reinforced throughout its entire length with a soft iron wire core.
3. A staple comprising a wire core covered. throughout its entire length Wth twisted paper mpregnated wth glue.
