FRANK WIRTH, of the Firm of Wirth and Company, Patent Solicitors, at
Frankfort on the Main, in the Empire of Germany. "IMPROVEMENTS IN SPRING
BEDS." [A communication from Franz Wengi and Leonhard Hämiker, of Zürich,
in the Republic of Switzerland.]
In carrying this Invention into practice the stuffing is so constructed that it can
be lifted completely away from the springs, thus providing for more easy
transportation, more thorough cleaning and ventilation, and greater facility for
repairs than in spring beds as heretofore constructed.
The spring mattress is constructed of two distinct parts, that is to say, the
springs and the stuffed frame cover which is placed over the springs thereby
forming a spring bed.
The spring frame consists of a wooden frame having webbing fastened from side
to side in both directions; on each cross of the webbing a spring is fixed.
In order to attach the springs in their proper position an arranging frame is
placed over the spring frame, having the length, width, and height required to be
given to the springs, only that the arranging frame is of the same height all over.
In order to regulate the springs temporarily .strings are stretched lengthwise
over the springs and nailed to the frame; the springs are then arranged, whereupon
the cross strings are placed and fastened and the temporary ones removed. Then
outside springs are tied by strings passing from the middle of the springs to the
frame and then to a top ring. Then follow two sets of strings serving to hold the
springs upright and to prevent them from leaving this position.
First. The stringing of the second and third rows of springs.
The springs pass between the springs on the first and fourth row to the frame,
the string is attached to the frame and passes to the first spring of the second row
where it is knotted, and then passes to another part of the frame where it is again
fastened to the latter; it is then carried back and knotted at another point, then
to the second spring where it is attached; this is continued up to the extreme end
of the row.
Row No. three is attached in the same manner as row No. two above
described.
Secondly. The stringing of the two central rows from one end to the other.

The string is attached to the frame, then passes to the first spring of the second
row where it is attached to the second ring, it then passes to the second spring of
the third row where it is attached to the third ring, then to the third spring second
row where it is attached to the fourth row, it is thus carried to the end of the said
rows and then returns, making zigzags on the opposite side.
The stuffed frame consists of a wooden frame with a stuffed ticking upper
portion.
A wooden frame is constructed with four sides and is somewhat smaller than the
frame to which the springs are attached so that it can rest on the same. The two
longer sides are somewhat cut away in their centre, the ends and end pieces being
of the same height. In order to stuff this frame a second frame is temporarily
placed within it, the whole is then covered with ticking and stuffed, after which
The spring frame is also provided with handles.
In order to ensure the stuffed frame being placed properly on the spring frame
an angle corner iron is attached to the latter at each corner.
handles are attached.
