6 Claims. (01. 290-44)
Figure 2 is a partial section therethrough,
This invention relates to automobile panels
and the like, such for example as are used in
automobile doors and bodies, and is illustrated
as embodied in an automobile door having novel
inexpensive but very strongymeans for attaching
‘ a panel of ?berboard to'a sheet-metal backing.
. An object of the invention is to provide inex
pensive fastening means of great strength which
can be manipulated with great rapidity, thereby
10 lessening the cost while at the same time increas
ing the strength of the joint.
To this end, the joint includes a tape of wires
secured at intervals to the metal backing, pref
erably by spot-welding, and with which are in
15 terlocked fastenings such as staples, headed fas
tenings of the type of single or double-pointed
tacks, or the like, all of which are adapted to be
showing the joint between the non-metallic ma
terial and the metallic backing;
Figure 3 is a view on an enlarged scale showing
the tape spot-welded at intervals to the metallic 5
backing;

‘
Figures 4, 5, 6, and "I are partial sections on an
enlarged scale, lengthwise of the joint; showing
the use of different types of fastenings; and
Figures ‘8 and 9 are respectively perspective and 10 '
elevational views on a still more enlarged scale
of the format fastening used in Figure 7.
Figures 1 and 2 illustrate a hollow panel for
an automobile door I0, having an outer sheet
metal face I! and an angle-section stamped sheet- 15
metal frame or backing I4 of any desired form.
The present invention relates to the means for
attaching to such a structure a sheet of ?berboard it used as an interior ?nish, or other sheet
clinched by being driven through the wire tape
against the metal behind it.

The novel joint includes‘a tape I8 of wires,
cally formed, pointed wires, or similar devices,
which may be screwed through the panel and, in preferably braided alternately over and under

25 tape from the reverse side beforeit is secured
to the metal backing, and, after it is so secured,
clinched on the outer face of the panel.
For the wire tape I prefer to use a braid of
wires carried alternately over and under each
30 other diagonally of the tape for the full length
of the tape. This gives a very strong joint, since
it insures that the particular wire which inter
looks with a given fastening will itself be secured -
directly to the backing. Also this construction
35 avoids any considerable open space in the tape,
since the wires are substantially in engagement
with each other, while yet the points of the fas
tenings easily ?nd their way between adjacent
wires because of the relatively great distance be

the backing M, as indicated at 20. Since the
different wires all extend at times into the mar
gins of the tape, it is almost certain that each '30
wire will be welded at several intermediate points
to the backing M, as well as at the ends of the
tape.

Various types of fastenings may be used to
secure the material IGAto the tape l8, but I prefer 35
to use fastenings which are readily clinched
against the tape l8 by being driven against the
metal backing 14. As examples, Figures 4 and 5
illustrate the use of staples or stitches 22 and of
headed double-pointed tacks 24. The points of 40

of the fastenings merely aids in clinching them, , the interbraided wires of the tape, even if de
as they readily ?nd their way between the wires ?ected by engagement with the wires. Moreover ‘
there is no possibility of some of the fastenings
even if they do not go straight.
The above and other objects and features of failing to engage and interlock with the wires, 45
asthere is no substantial space anywhere be

Another desirable method of securing the panel
tions, will be apparent from the following de
scription of the illustrative embodiment shown in is illustrated in Figure 6 in which are shown
staples or stitches 26 the prongs of which are in- 50 ‘
the accompanying drawing, in which:
Figure 1 is a side elevation of a panel for an serted through the tape l8 from the side next to
the metal backing it prior to fastening the tape
automobile door, with part of an overlying?n
on the backing so that the body of the staple lies
ish sheet of non-metallic material such as ?ber
board or the like broken away at one side to show between the backing and the tape. After the
tape is secured, the panel it is forced over the 55
the metal backing;

backing l4. Between its ends, at intervals, the
tape may be spot-welded at its margins only to

on the outer face of the panel.

Figures 7-9 illustrate still another fastening 28
comprising a pointed wire which may be doubled
back on itself, as at 36, to form a head and be
formed with one or more helical or spiral coils 32
adapted to be'screwed through the panel i6, and,
in eil'ect, be threadedly interlocked with the wires
of the tape iii.

While particular constructions have been de
scribed above, it is not my intention to limit the
scope oi the'invention byv that description, or
otherwise than by the terms of the appended
claims.
