2 Claims. (Cl. 308—217)
This invention relates to roller bearings and
particularly to a cage construction in which the
rollers are assembled, and has for its object a
one-piece sheet metal cage so constructed that
- 5 the heads of the cage are connected together by
a tie bar integral with both heads, and also by
additional tie bars, one of which is integral with
one head only and independently secured to the
other head, and another of which is integral
with the latter head and independently secured
to the former head.
It further has for its object a sheet metal cage
formed from a single blank with spaces between
the tie bars for a maximum number of rollers.
15
It further has for its object a single piece sheet
metal cage which can be struck from a sheet with
a minimum of waste material.
The invention consists in the novel features
and in the combinations and constructions here
20 inafter set forth and claimed.
In describing this invention, reference is had
to the accompanying drawing in which like char
acters designate corresponding parts in all the
views.

Figures 1 and 2 are, respectively, end and side
elevations of this roller bearing.
Figure 3 is an enlarged inner face elevation
looking toward one of the heads with some of the
rollers being shown in end elevation and others
30 in cross section, the tie bar integral with both
heads of the cage being shown in section, the tie
bar integral with one head only being shown in
end elevation, and a similar tie bar integral with
the other head only being omitted.

Figure 4 is a sectional view on line 4~—4, Fig
ure 3.
> Figure 5 is a plan view of the blank from which
the head is formed.
Figure 6 is a fragmentary plan view of the
40 sheet of metal from which the blanks are stamped
showing the out-lines of the blanks thereon and
the arrangement by which there is a minimum
amount of waste material.
This invention comprises a roller bearing in
45 eluding cage and rollers assembled in the cage,
the cage being of a one-piece sheet metal struc
ture comprising opposing heads in which the ends
of the rollers are mounted, a tie bar integral
with both heads, and a tie bar integral with each
50 head and secured at its end remote from the head
with which it is integral to the other head.
The invention further comprises a one-piece
portions and integral with both, a bar extending
radially from each ring portion and integral
therewith and at an angle approximately of 120°
to the diametrical line of the former bar, and
located on opposite sides of such diametrical line,
whereby the blank is in the general form of a
letter Z with the ring portions at the apex of the
angles of the leg and arms of the Z.
I and 2 designate the heads of the cage, these
being ?at rings having openings 3 therein for re
ceiving the axles 4 at the ends of the rollers 5.
6 designates the tie bar common to or integral
with both heads, and ‘I and 8 designate respec
tively the tie bars integral with the heads I and
2 respectively, and each secured at its end re 15
mote from the head with which it is integral to
the other head. That is, the end of the‘ bar ‘I is
integral with the head I and secured to the head
2. The bar 8 is integral with the head 2 and se
cured to the head I. The heads I, 2 are provided 20
with openings as 9, II], for receiving the ends of
the bars 8, 1, respectively. The bars 1 and 8 may
be secured to the heads 2 and I in any suitable
manner, usually by riveting or welding.
As seen in Figures 5 and 6, the blank is formed 25
from a sheet to have ring portions which, when
the blank is formed up, provide the heads I, 2,
the bar extending diametrically of both ring por
tions and integral therewith and which provide
the tie bar Ii, the bar integral with the ring por
tion constituting the head I and extending in
a radial line at an angle of about 120° to the
diametrical line of the bar 6 of the blank, and
constituting the tie bar 1, when the blank is
formed up, and the bar integral with the ring 35
portion which forms the head 2 and extending
radially therefrom at an angle of about 120° on
the opposite side of the diametrical line of the
bar 6, and providing the tie bar 8.
The blanks are stamped out from the sheet, 40
after the manner about as shown in Figure 6. It
is obvious that a maximum number of blanks can
be struck from a sheet with minimum of waste.

integral with both heads, a tie, bar integral with

head with which it is integral to the other head,
both heads and connecting the same, and a pair
of additional tie bars connecting the heads, one
of the pair being integral with one head and fas

the heads are in axial alinement when the heads
