(Cl. 24-221)
This invention relates to improved and service
able cowl fastening means and the object thereof
the disposition of the strap means to preclude
accidental dislodgement of the cross pin from its
is realized in the provision of a novel cowl fas
interlocking relation with the keeper means.
tener wherein an outside plate member rotatably
carries a bolt having a cross pin adapted to be
removably snapped on transversely spaced resil
ient straps integral with and extending longitudi
nally of a relatively thin sheet metal spring plate
desirably retained on an inside plate member
to which the outside plate member is disen
gageably clamped, the spaced straps characteriz
ing loop means with the bottom wall of the spring
plate and having free portions disposed at al
ternate opposite ends of the bottom Wall and
retained slidably in adjacent but appropriate
bearing means also integral with the bottom wall,
‘ the arrangement being such that each of the re
silient and relatively wide straps include spaced
and alined keeper means to removably retain the
cross pin in a desired elevated position for hold
ing the outside plate member in the desired
clamped relation against the inside plate member.
' The invention has as another object the pro
vision of a cowl fastener wherein a greater torque

Fig. 14 is an end view of the key shown in

In all of the embodiments disclosed the cowl
fastener comprises a spring plate broadly de
noted SP desirably secured to an inside plate
member I0, and a rotatable bolt B having an en
larged slotted head I2 rotatably guided .in the
countersunk portion or bearing I3 of the out
side panel or plate member I4.
According to the invention, the one piece re
is required to disengage the cross pin of the 25
silient sheet metal looped shaped spring plate or
rotatable bolt from the keeper means of the
keeper broadly denoted SP is characterized by a
spaced straps than the torque required to operate

portions or notches I8 adapted lto re

movably receive shank I9 of the bolt B and the
-base plate but it is desirably resistant to acci
dental dislodgement therefrom.

In Figs. 9 and l0 the beveled head I2’ of the bolt
to engage or disengage the cross pin with or from
the resilient straps S. Of course where the cross
pin is interlocked With the keepers the outer plate
member I4 is firmly clamped against the carrier
Iíl and vupon disengagement of the crosspin from
is provided with alined recesses 4G adapted to
register with correspondingly spaced notches 4I
of a collar 42 rotatably retained on the beveled
head I2' by the inclined lugs 43.
The key K is provided with the oliset termi- I
nals 44 adapted to be inserted into notches 4I joi
the collar 42 and the latter may be rotated rela»
tive to the beveled head I2’ whereupon the ter-`
minals 44 may enter the recesses '43, and there-f
after the key is utilized to rotate the bolt. Y, Of
the strap S the latter retracts and the cross pin ,
may be projected through the alined openings I6,
and thereafter the bolt is withdrawn from the
opening 41 and arranged on the bearing I3. The
cross -pin is >prevented from passing through open
- ing '46 of the bearing I3 in that the length of the
pin is larger thanA this opening.
In‘ac‘tual’practice, the thickness of plate mem
bers I0 and I4 vary'in tolerances and by the pro
vision of the longitudinally displaceable and re
silient straps S, these tolerances may be compen

the head of the bolt may be provided with a single
diamctrically disposed slot 45 as in the forni shown
.in Figs. 2 and 3.
The relatively wide resilient straps S are nor
sated for in that the keepers are readily vdepres
sible upon the operation of 'the cross pin and
automatically retractible to interlock therewith. Y
This is true in connection with. all of the em
bodiments disclosed. In Figs. 9 and l0, the îiòat
relation of the spring plate S’P’ allows "for
quick alineinent lthereof relative to the carrier
I0 upon insertion of the Vcross kpin CP through the

placement of the keeper means 23.

In all of the embodiments disclosed, when the
cross pin is interlocked with the keeper of the
resilient straps S, a greater torque is required to
