the form of ears projecting at proper inter completely covering the same, said tube
vals from the long edges of the sheet or strip having integral clips engaged with the upper
out of which the sheathing is formed. These turns of the outermost springs to secure
ears may conveniently be disposed in groups them to the frame.
2. The combination with a group of verti

ears 4 distributed along one of the long edges cal coiled springs, of a smooth continuous
of the strip or sheet. each of these ears lying tubular member surrounding the same, said
between two ears, 5, 5 on the opposite edge tubular member being provided on the un

three ears constitutes a clip or fastening outermost springs and securing the latter to

4. A frame for a spring cushion compris 100

spaced with respect to each other that when ing a wire core, and a covering for the core
the frame is placed about a nest or a group of consisting of a tube formed of a sheet of
springs. each set of ears will register with metal bent around said core and extending

and the corresponding ears. 5, 5 are then bent

inwardly and upwardly. The length of the
ears is such that after the ears have been bent
about the wires of the springs until their free
ends come in contact with the body portion of
the sheathing, closed bearing seats are pro
vided for the wires of the springs. and these
115
wires are held to the frame. It will be seen,

however, that the connections between the
springs and the frame are in the form of
hinges that permit the springs to swing on
the frame about axes parallel with the long
axes of the corresponding sides of the frames.
It will be seen that in the completed cush
ion the exposed surface of the frame is con
tinuous and smooth, the joint in the sheath‘
ing and the holding clips being on the un
derside.
If desired, the wire or core 2 may be omit
ted. Furthermore, it will be seen that the
sheathing may be said toiconstitute a series
