UNITED STATES.- AlUI-flENT oFFIcE.
EDWARD LQwooD, oF-mifrnoir, MIGHI'GAN/ To all whom #may concern.'
Detroit, inthe county of V'Vayne. and State of Michigamhave invented a new and' Improved Means for Fastening Soft Material to 4Sheet Metal, of which the following is a specification. V
This invention has referencev to fastening one or more blocks or pieces of relatively soft iiexible material, such as felt, to a piece f -rectangular or Y polygonal Cross section is preservedthroughout. Near l 'the extreme be plane to forma very of sheet metal, such as soft tinned plate. In connecting such parts itv is customary to either employ screws or Ysimilar '-devices,V
which is objectionable on account of the additional expense for labor and material, or to cement the parts together, which is unreliable, particularly where the swab is to be dipped in gasolene or other solvent.
In accordancewith the present invention, however, the relatively soft block of compressedfelt or the like is first perforated to form a hole or cavity of suitable size, the parts are assembled in the desired relation, and the metal is drawn, slitted and bent, by means of a suitable tool, centrally of the perforation to form a plurality of diverging tongues which hook into or about the soft material to firmly bond the latter to the sheet metal. A single fastening thus formed not only secures the parts together tightly against any tendency to separate, but also affords a practical means for preventing rel- -ative rotation; the perforation constitutes a vent which is highly desirable for -certain purposes, as will be pointed out later. It will be noted, moreover, that the connection requires no extra material, and may be rapidly made at a nominal labor cost.
In the drawings, Figures l, 2, 3 and 4 are sectional views showing dierent stages of the operation as applied for the purpose of securing a swab to a can cover. Fig. 5 is a perspective view of the preferred tool. Fig. 6 is an inside perspective view showing the tongues as slit and bent from the can cover, and Fig. 7 is an inverted plan view of the finished cover and block.
l indicates a sheet of thin soft metal, in this instance intended as a can cover and provided with the Hange suitably threaded for application to a paper or other can, not shown. A. sheet or block of felt or the like appears at 2, said block being adapted,
when suitably secured to the cover, to form,
specificati@ of Lettersratent.
Y y' Y Vaswab'for-'which'the Be it'known that I, EDWARD L. VI VooD, a` citizen of the United States, and resldingat grip orl handle. The soft material isperforated at?)` to form an opening, preferablyl Patented J une n14, `1921.` Application filedvnay 9, 1919. seri'ailNo. 296,015.
cover constitutes -a hand,
i less number of sides, saythreeor five. This.
tool isground to a gradualf-taperor curvature of' aboutthe configuration indicated in the drawing, -it being observed that the correspond to the perforation 3 and in alinement with the tool 4, either the tool or die is caused to approach the other, the tool being central to the perforation 3.
The first stage of the operation, that is, the drawing stage, is indicated in Fig. 2 and forms a substantially pyramidal indentation with Vthe tool shown) of considerable size.
s the relative movement continues, Ithe metal is pierced and the sharp edges of the tool slit the sheet radially, and the curved faces simultaneously gradually bend the triangular tongues 9 over-see Fig. 3- until the points strike the felt, after which a further movement for the most part spreads the tongue and embeds the points well into the material. In this latter stage, also, the base portions of the tongues are pressed outwardly into the adjacent soft material to form a rectangular or polygon cir` cumscribed on the opening 3 so that a very rigid holding action against relative rotation 'is obtained.
The opening 3 is of the greatest importance since it permits the free formation of the tongues, at least up to the stage indicated in Fig. 8, the particular shape which they assume being dependent on the angle between their sides, 'the stiffness of the metal, and the curvature of the tool. The bending stress may be regarded as being applied successively to very small elements parallel to the corresponding base, and after a given element has swung away from the tool its relation to the next wider element is not again changed (except at the final stage when those parts near the base may be flattened somewhat by the reaction terial by a substantially radial movement,"
and a firm gripping isv insured. For some purposes more' than one fastening may beV desirable. Y
When the device isapplied to a `cover of a tire patch can, the swab is attimes Wet K p n l l l. In combinatioma sheet of metal and of relatively vsoit corn-` vvith gasolene for cleaning the tube preparatory to the application of a patch thereto. The patches are, of course, normally kept in the can, and when the cover `isreplaced Would be subject to deterioration from the vapor of -thegasolene but for the fact that it may readily escape throughthe vent. generally in venting fastenings. f
It is also obvious that the invention may be utilized Whether the element 2j is formed integraler in tvvo or more layers of the same or different thicknesses such as the sheets 2 and2, Fig. 4; and in such cases thesecuring of the plurality of sheets to- Ugether, as distinguished from their attacha perforated swab This Jfeature 1s obvlously'of value y y sheet metal end and a perforated blocl; of
nient to the metal plate, may be the primary object.
Other changes lthanrthose indicated may be made Without departingv from the spirit of the invention, and I' do not, therefore, VWish to be limited except as indicated by the subjoined claims.
I claim pressed material, sald sheet of metal having a seriesk of integral tongues struck up Within the limits of the perforationiny the swab and;` bent over in hook-like form into the body of the swab. i v t .4
2. A shcetmetal can cover including a compressed fibrous material attached to one face of the sheet metalend by a plurality oftongues integral `withf the sheetmetal end,
said tongues curving into the yperforation in said block and diverging from a common center and piercinthe fibrous material. l
