ver is again brought in contact with the pin
H, and the pawl g being in engagement with
the roller will assist in preventing backward
rotation of the same. It will be noted that
5 the end of the pawl g also engages the pin II,
and in the normal position of the parts or ad-
justing devices will provide against acci-
dental disengagement of the said pawl.
The adjusting devices provide a ready and
10 convenient means of turning the roller and
holding the adjustment of the same, and the
said devices lying closely against the side rails
will be out of the way, so as not to offer any
obstruction or catch in the hair mattress and
15 other covering which may be placed upon the
wire fabric.
Having thus described my invention, what
I claim as new, and desire to secure by Letters
Patent, is--
20 1. A bed-bottom frame for wire matti esses,
comprising the side rails connected to each
other at one end by a cross-piece, a roller jour-
naled in the other end of the side rails, said
roller having a circumferential series of holes
25 at each end, a pawl pivoted to the inner side
of one of the rails to engage one set of holes
in the roller, a lever fulerumed on the other
end of the roller, a pawl pivoted to said le-
ver and provided with a projecting rear end,
30 and a pin projecting from the adjoining side
rail to contact with the lever and pawl, sub-
stantially as shown and for the purpose set
forth.2. A bed-bottom frame for wire mattresses,
comprising the side rails connected to each 35
other at one end by a cross-piece, a roller jour-
naled in the other end of said side rails, the
roller having a circumferential series of holes
at each end, a pawl engaging one set of holes,
a lever fulcrn med on the spindle at the other 40
end of the roller, a pawl pivoted to the lever
and provided with a projecting rear end, and
a pin limiting the throw of the lever in one
direction, the said pin being tapered from its
outer end inward, substantially as shown and 45
for the purpose set forth.
3 In combination with a frame for wire-
spring mattresses, of a roller, short spindles
let into the ends of said roller, metal caps at-
tached to the ends of the roller to hold the 5o
spindles in place, said caps each having a cir-
cumferential series of holes, a pawl pivoted
to the frame to engage one set of holes, a le-
ver fulcru med on the spindle at the other end
of the roller, a pawl pivoted to said lever and 55
adapted to engage the other set of holes, and
a pin projecting from the frame to limit the
throw of the lever in one direction, substan-
tially as shown and for the purpose set forth.
In testimony whereof I affix my signature 6o
