Application December 15, 1936, Serial No. 116,004
12 Claims.
This invention relates to fastening devices and
particularly those of the type constructed of metal
sheet or strip material such as spring steel, sheet
metal, cold rolled metal and the like.
6
The fastening devices of this invention com
prise what may be termed clip devices composed .
of relatively yieldable arm or jaw elements adapt
ed to engage opposite faces of a thickness of work
in applied position.
10
A
Clip devices of this type are made in various
forms such as to engage a plurality of layers of
work to retain the same rigidly in desired posi
tion; other forms carry a fastening means de
signed to receive or be received in a cooperating
element or part in applied fastening position in an
installation. Still other forms have> an element
or elements so designed as to support or clamp
an object or a plurality of objects relative to the
material, in which the arms formed from such
blank are disposed in separate planes and pro
nounced locking means are Vprovided to positively
lock and retain the device in the desired position
to which it is applied.
Further new and useful objects'and features of
the invention will be apparent to those skilled in
the art as the description thereof proceeds, at
tention being had to the accompanying drawing
in which like reference characters designate like 10
parts throughout the same and in which:

sion thus minimizing possibility of the device be
coming loosened from such position.
It is a further object of this invention to pro
45 vide a clip device which may be constructed from
a single thickness blank of material of suitable
size and configuration such that relatively yield
able arms may be provided from a minimum of
stock without loss or waste of material.
50
A still further object is to provide a clip device
constructed of a single thickness blank of ma
terial and in which the jaws are formed entirely
having integral bolt engaging elements.

Fig. 18 is a top view in perspective of the> clip
device of Fig. 17.
A clip fastening device of the type shown in
Figs. 1-3 inclusive is preferably constructed from
a blank outline such as shown in Fig. 1. The
blank outline may comprise a substantially rec
from such blank and disposed in separate planes.
Another object is to provide a clip fastening
tangular section, provided from either sheet
means constructed of a single thickness blank of
stock or strip stock of suitable width. ` The 55

stamping of the said blank I is such that it is
severed, slit or cut along lines within its periph
ery to provide integral sections, 2, 2, 4, and il
as ‘shown in Fig. 1; during the stamping oper
and disposing them in spaced relation. This
greater effective length in the imperforate arm
is important in that various forms of fastening
and securing elements may be formed or struck
ation' or in .-a separate, distinct step the said in
' therefrom and so designed as to receive or be
` tegral sections are deformed into spaced rela
received in a cooperating fastening element or
object to be secured.
Among fastening or securing elements which
may be formed or struck from the imperforate
arm 3, Figs. 2 and 3„and 13, Figs. 5 and 6, are
cooperating elements defining a snap stud adapt
tion as shown in Fig. 2 to provide a plurality of
integral jaws or arms, one of which, designated
3, 'extends out of the plane of the base which
10 includes arm members 2-2’ and which hereafter
is referred to as one arm of the device. As shown
in Fig. 1, one arm element may be stamped in a
substantially V-shape at its free end whereby
the complementary section 4 thereto, presents a
ed to seat into a cooperating socket, or a socket
adapted to receive a cooperating snap stud; in
ternally threaded elements adapted to receive a
substantially \_l-nctch configuration denning
bolt, or externally threaded elements adapted to
prongs or spurs 5, 6. 'I'he end section 4 is pref
erably slit along lines 1, I in order that such end
may be bent as shown in Figs. 2 and 3 to provide
receiveL a nut: auxiliary cooperating elements
designed to receive an object such as a line. wire,
tube, or cable or the like; and auxiliary clip ele
ments designed to receive a post, tube or the like.
As shown in Figs. 'I and 8 the imperforate arm
I I may be deformed into an element such as I5
adapted to clamp an object such as, for example,
a wire W against the adjacent surface of the
spurs 5, i and dispose them in upwardly extend
20 ing relation' toward -the cooperating arm I. The
opposite end section l may be deformed either
upwardly or downwardly with respect to the arm
‘with which it is integral to provide a blow-re
ceiving element which may be struck to advance
25 the device to desired fastening position. As
shown in Figs. 2 and 3 the inclined end section
4 serves a dual purpose in that it carries the
, prongs or spurs 5, I rigidly in upwardly extend
,ing, most effective relation for anchoring into
30 the work, and also provides a n_ared entering end
support S, Fig. 8. A plurality of such elements II
obviously may be provided on the arm I_I whereby 25
a plurality of objects may be clamped.
Fig. 9 discloses a modified construction where- `
by the free end of the imperforate arm I3 may be
deformed into a return bend adapted to clamp
and support either one or a plurality of objects
to the device facilitating application thereof to
such as line L, and wire W.

ture in work. In use, this form of device may
be applied to fastening position with the open
end as the leading end; suitable force, such as
In Figs. 10-12 inclusive is shown a ‘form of de
vice wherein the free end 26 of the arm I2 may
be deformed to retain a nut element N; an auxil
iary element 25 may also be provided by striking
hammer blows, is applied to the end section 9
a section from the opposite end portion of arm
-
whereby the arms 2, 3 move into desired fasten
I3, which auxiliary element may be deformed to
ing position gripping opposite faces of a support
engage an opposite side of the nut N as shown
ing structure or layers of work. >Since the en
40 tering end of the device including the inclined
section 4 presents a flared mouth to the jaws or
arms 2, I, the device is readily seated on being
applied, and, as the device is driven home in one
direction the prongs or spurs glide past the ad
45 jacent work surface until the device is in desired
position whe'reupon said spurs dig into and em
bed themselves in the work under tension exerted
by the arms; thus .the device is anchored in de
sired position and reverse movement and possi
50 bility .of loosening thereof is minimized and in
many instances completely eliminated. 'I'he ten
sion supplied by the arms is provided by the spe
ciiic spacing thereof with respect'to a certain
thickness of work, their spacing in normal posi
v55 tion being less than the overall thickness of the
work, whereby the work is gripped under extraor
dinary tension of the arms attempting to as
sume their normal spaced relation. Unusual

nut N from the underside thereof. A clip device
assembly of the type shown in Fig. 11 may be
advantageously employed in an installation such
as shown in Fig- 12 wherein the work piece S is
readily accessible from one side only. On ap 45
plication, the device is inserted, free ends for
ward, such that arm_ Il carrying the nut N- is
passed through the slot orvaperture A and' ad
vanced to desired position by hammer blows ap
plied to end section 9. The home position,
wherein the prongs orvspurs I, 6 anchor the de
vice in position, is such that the threaded open
ing of the nut is substantially in line with the
aperture .A' of the support S. A jig pin or the
like may be employed for fully aligning the nut
opening and the aperture A, whereupon a plate
or member S' to be supported may be secured by
a bolt applied to the nut through the aperture
2l in the clip.

each other such that their combined. gripping
action in fastening position is most effective.
The form of device disclosed in Figs. 4-6 in
65 clusive. is substantially similar in operation to
that described in connection with Figs. 1-3 in
clusive but is distinguished therefrom in ’that the
armV I2, which~ maybe said to be in the base of
the device, is provided by bending the same out
of the plane of the cooperating arm I3. In the
construction of this form of clip fastening, the
upper imperforate arm I3 is thus provided with
a greater keilfective length in that portions of the
signed to serve as a nut supporting means is
shown in Figs. 13 and 14 wherein the free end
36 of arm I3 and the tail section l5 of the blank
baserather than the upper arm as in Figs. 1-3
75 inclusive are utilized for connecting the arms
may be suitably deformed as shown in Fig. 14 '
to retain a nut element. An `aperture 31 in the
clip `permits insertion of avbolt to the underside
of nut N for securing a plate or member S' rela
tive to support S_. In operation and use this
form of clip device for retaining a nut element
is similar to that described in connection wit
Figs. 10-12 inclusive.
'
Figs. 15 and 16 show a clip construction where
in integral bolt engaging means are struck and
formed from the imperforate arm thereof. As
shown, the bolt engaging means may comprise u

and 14. It is obvious however, that this type'of“ 'f movement thereof in _an opposite direction, said
10 nut clip device has many advantages over such. arm beingl spaced from. "the‘îbase
andhaving
forms of nut-carrying clips invthat the use of a .
separate nut element is dispensed with, thus, elim- l '
inating the necessity of a distinct operation for
assembling the nut and also a separate opera#
15 tion of stamping and deforming elements -for re
taining the nut on the clip member. Also the
nut clip devices of Figs. 15 and 16 may be made
comparatively small in size for securing light
weight work and constructed from a minimum
29 amount of stock without loss >or waste of ma
terial.
Figs. 17 and 18 show an alternateconstruction
similar in application and use to that disclosed
in Figs. 15 and 16. As shown in the installation
represented in Fig. 1'7, the bolt engaging means
are formed from an irregular shaped aperture
54 which when deformed presents elements 55,
56 adapted to receive in threaded engagement the
threads of a bolt for securing in desired position
30 a plate or member S to be supported.
The various forms of clip devices herein dis
closed _and described have many advantages over
the prior art structures chief among such ad
vantages being the facility with which the de
35 vices may be applied to fastening position by
reason of the flared entering end.
Another advantage is in the great saving of
time and operation in construction of the de
vices in that clip structures of the type disclosed
may be formed by a single stamping and form
ing die in one operation. Clip devices hereto
fore known required in their construction in ad
dition to the stamping operation, a separate tool
and bending operation for providing a U-shape
45 defining the spaced arms of the clip.
A further advantage resides in the unusual
holding power of the clips in fastening which
holding power is accomplished by the use of pro
nounced anchoring spurs or prongs simply and
effectively provided without requiring the use of
added material.
A still further advantage is provided in that
clip devices of the type described may be formed
from a single thickness of metal strip from a
minimum of stock and without loss or waste of
material whatsoever.
