Application March 23, 1935, Serial No. 12,577
10 Claims. (Cl. 280-106)
This invention relates to motor vehicles .and being taken at lines 3—-3 and 4-4 respectively of
refers more particularly to frame structures em Fig. 2.
Fig. 5 is a side elevational view of my reinforc
ployed in such vehicles, either as a chassis frame
ing member.
" adapted to receive the vehicle engine body struc
In the drawings I have illustrated my frame 5
, 5 i'ture or as a frame adapted to be built into the
body structure as a unit;
‘In motor vehicle frame structures employing
rail members such as the side longitudinally ex
tending rails, it is desirable to maintain a sub
10 stantially uniform rail cross-section along its
length, especially with the more desirable types
of'rail structures suchas the “box” or other hol
low type, for example, since such uniform sec
tion may be readily rolled at a minimum of ' cost
,15 when kept uniform in its section. I mention the
box type of frame since a frame element of such
type affords the desired high degree of stiifness
and lightness of weight in the broader aspects of
my invention, other forms of hollow rails may
20 be employed if desired.
Since the frame structure and its component
elements are subjected to stresses, usually bend
ing stresses, of varying intensity along the length
thereof, it is necessary to provide the frame ele~
125 ments with suf?cient rigidity at‘its point of great
est stress.
However, if the. section of the frame
element is maintained uniform, then this requires
a section which is excessively heavy at other
,_.__30'
points, usually at the ends.
It is an object of my invention, to provide a
frame structure or rail‘ element thereof which
may be made of uniform section throughout its
length and at the same time providing a simple
and inexpensive reinforcing structure at the points
"35 of maximum stress, the reinforced rail being
preferably of the aforesaid box type to provide
the desired high degree of rigidity for the weight
of material used. My reinforcing structure is of
a character affording great strength for the total
40 weight of materials involved.
A further object of my invention is to provide an
improved frame reinforcing structure which is of
a self locating nature when app-lied to the frame
rail, thereby facilitating the assembly process of
45 the reinforcing member with the frame rail.
Further objects and advantages of my inven
tion will be more apparent as this speci?cation
progresses, reference being made to the accom
panying drawing illustrative of one embodiment
50 of the principles of my invention and in which:
Fig. 1 is a top plan view of the assembled frame
structure.
Fig. 2 is a side elevational View thereof.
Figs. 3 and 4 are detail sectional perspective
55 views along a reinforced frame rail, the sections
structure A comprising the longitudinally extend
ing side rails or sills l0 and the connecting cross
members ll of any desired form and arrange
ment. For illustrating my invention I have
shown frame A as the well known chassis type 10
having the usual front and rear kick-up portions
l2 and I3, although such frame may constitute
a part of the motor vehicle body structure if de
sired.
Rails l0 arepreferably of the box type and 15
may be formed by rolling the steel tube-like and
welding longitudinally at a corner l4 although
other methods of fabrication may be employed if
desired as I do not claim such fabrication method
per se as a part of my said invention.
If de- 20
sired, the frame members or elements I0 and It
may be fabricated or built up with a plurality of
separate channels. In any event, these members
may be regarded as elements of the frame struc
ture.
25
Secured to each rail I0, preferably by welding
thereto, is my channeled reinforcing member l5
which is preferably U-shaped in cross section for
maximum strength and lightness of weight. The
member I5 is preferably secured to a rail Ill be- 30
low the latter with the web I6 spaced from rail
Hi to provide a relatively deep light section of
great rigidity. The side v?anges of member 15
extend upwardly and overlap the lower side por
tions of rail in in engagement therewith, the rein- 35
forcing member being welded to rail Ill asindi
cated at 11.
.
In order to lighten the weight of the reinforc
ing member l5, the web l6 thereof is preferably
formed with a series of perforations N3 of any 40
suitable shape. The perforations in web l6 do not
appreciably lessen the rigidity of the frame struc
ture.
The ends of the reinforcing member l5 are pref
erably tapered at 19, the web It curving toward 45
rail. Thus, when member I5 is applied to the
rail, these tapered ends engage the rail and thus
provide locating means or stops whereby the rein
forcing member is easily and properly applied for
the welding attachment to the rail. In the frame 50
illustrated, the tapered ends 19 ?t rail l0 adja
cent the inner portions of the kick~up portions
I2 and I3. It will be apparent that a frame of
any desired localized rigidity may be provided by
varying the depth of the attaching member I5, 55
