Improvements in Mattresses for Baby-carriages and Cribs.
I, ARNOLD WAGEMANN, Judge, of 35, Windmühlenwall Peine, in the Empire of
Germany, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
The subject of the present invention is a mattress for baby-carriages and cribs,
having an arrangement for receiving the urine when the bed is wetted. By this
means the child always lies dry, a matter of much hygienic importance.
On the accompanying drawing.
Figure 1 shows a cross-section of the improvement.
Figure 1 is a detail-view to be hereinafter referred to.
Figure 2 is a side-elevation corresponding to Figure 1, and
Figure 3 is a plan view of the mattress fitted with receptacle.
The mattress A is made of such size as to fit the baby-carriage or crib, and
in the centre of it a trough B of sheet metal, or some non-porous material, is
let in. Across the top of this trough a cover of reticulate or open material is
tightly stretched, and on this extended, elastic cover the central portion of the
child's body lies. The urine runs through the cover and collects in the removable
trough below, so that it can be readily removed. By this system of running of the
urine, the swaddling-clothes retain a minimum of moisture, wherefore the body
remains nearly dry.
Slate dust, or other absorbent medium, may be spread over the bottom of the
trough B, in order to lessen the smell and prevent the urine from being thrown
about when the carriage is wheeled.
The trough B may be partly open at the ends if desired as shown in Figs. 1 and 2.
A convenient manner of securing the cover P stretched across the trough B,
so as to be readily removable, is shown in Figure 1. The upper edges of the
walls are bent over to form lips or flanges, the trough extremities of which are
then again bent round or beaded. The staves or rollers S, around which the
cover is laid are then pushed up from below, on either side, between the wall of
the trough and the beading, as shown by dotted lines in Figure 1, and 1^, whereby
the cover is firmly held in place. To stretch it tightly, first one roller S with one
edge or side the cover round it, should be adjusted under the flange on the one
side of the trough, and then after drawing the material tight, the other edge of
the cover wrapped round the second roller S and pushed firmly under the opposite
flange. To remove the cover, the rollers have only to be drawn out in the
direction of their length.
The parts of the mattress A. which come in contact with the trough B, may
conveniently be covered with leather in order to preserve the mattress.

invention, and in what manner the same is to be performed, I declare that what
I claim is
1. A mattress for baby-carriages and cribs, comprising a mattress body (A),
provided with a central recess or opening adapted to receive a trough or recep-
tacle (B), having a reticulate or openwork cover (P) stretched over it, all sub-
stantially as and for the purposes hereinbefore set forth.
2. A mattress for baby-carriages and cribs, comprising a mattress body (A),
adapted to receive a trough or receptacle (1) provided with flanged or lipped,
and turned over or beaded edges, and reticulate or openwork cover (P) for the
trough, passing over two staves or rollers (S), adapted to pass under the said
flanges or lips, and to be wedged between the wall of the trough or receptacle
and the turned over or beaded portion of the flange, all substantially as and for
the purposes herein before set forth.
