CARL PIEPER, Civil-Engineer and Patent Agent resident at 109-110 Gneisenau-
strasse, Berlin S.W, Prussia, "IMPROVEMENTS IN HAMMOCK-CHAIRS
A com-
munication to me from Emil Meyer, residing in Hannover, Kingdom of Prussia,
German-Empire
This invention relates to improvements in hammock-chairs destined especially
for invalids.
The chair belongs to the class of hammock-chairs constructed of two rectangular
frames, a long one and a short one, pivoted together crosswise, and to the
upper transverse bars whereof is attached the hammock, i.e. a cloth or cushion
forming the seat and back of the chair.
The first improvement consists in arranging at the top of one or of both parts
of the chair an axle adapted to be turned by hand, and to be retained in its
position by a ratchet wheel and pawl or other like means, and in attaching the
hammock to such axle or axles. Preferably the hammock is connected to the axle
or to either of them by a special piece of cloth, leather or the like, or by a
number of straps, served to the underside of the former. This arrangement allows
the hammock to be stretched or slackened at will.
According to the second improvement a frame provided with a cloth or cushion,
is arranged to slide in guides attached to that one of the aforesaid frames which
extends from the back upward to the front. When drawn entirely out, this
sliding frame engages with two pivots in corresponding hooks on the guide-
carrying frame and is locked therein by spring tumblers. It can then be turned
on these pivots and maintained at the desired height by means of adjustable stays,
so as to form a support for the legs of the person using the chair.

CARL PIEPER, Civil-Engineer and Patent-Agent, resident at 109/110 Gneisenau-
strasse, Berlin SW., Prussia "IMPROVEMENTS IN HAMMOCK-CHAIRS, & com-
munication to me from Emil Meyer residing in Hannover, Kingdom of Prussia,
German Empire
This invention relates to hammock-chairs such as are constructed of two
rectangular frames of different length connected together crosswise and to the.
upper transverse bars whereof is attached the hammock, i.e. a cloth or cushion
forming the seat and back of the chair, and the object of the improvements is to
provide the chair with means for stretching and slackening the hammock and for
extending the seat of the chair, and thereby to render the same particularly
adapted for the use by invalids.
On the annexed sheet of drawings Fig. 1 shows the chair with the extension of
the seat deposited under the latter, and Fig. 2 with the seat extension drawn out.
In Fig. 2 the upper-part of the frame a is shown in section.

The two frames a and b are connected together at a in any known manner,
preferably by pins or pivots in combination with means for adjusting and
maintaining the frames in the desired relative position. The hammock c is
attached with one end to the cross-bar d of the frame b as usual. With its other
end it is so fixed to an axle f at the head of the frame a that, when this axle is
turned by means of a handle g, a portion of the hammock will be rolled upon the
axle and the hammock thereby shortened or stretched. A ratchet-wheel h
and pall or other equivalent device, serve to keep the axle in the position
imparted to it. By releasing the ratchet wheel and causing the hammock to unroll
from the axle, it will become slack. By preference, the hammock is connected to
the axle by a special piece e of canvass, leather or the like, or by straps, served to
the underside of the hammock, so that only the said piece or straps will be rolled
on the axle while the end of the hammock hangs over the same. Especially when
the hammock consists of a cushion, as shown in the drawing, this arrangement will
have to be adopted. Instead of placing the axle f at the head of the frame a, it
may be mounted in the frame b, or there may be an axle to attach the hammock
to, in either frame.
According to the second part of the invention the frame k having a piece of
cloth or other suitable material, or a cushion fastened in it, is arranged to slide in
or upon guides attached to the frame or chair-part b, and which may be made of
angle-iron. The frame k is provided at one end with pivots m, which, when the frame
is drawn entirely out, as in Fig. 2, engage with the hooks n on the chair-part b,
while tumblers r, that may be provided with springs, serve to lock the pivots in
the said hooks. The sliding frame k can then be turned on these pivots and may
be adjusted at the desired height or inclination by means of the stays or legs o
hinged to the frame and fitted with a locking device, such as the spring-catch p
adapted to engage with the holes in the bow q. The sliding frame k, when drawn
out, thus forms an extension of the seat of the chair and converts the chair into a
couch.
Having thus described the nature and object of this invention and the manner
in which it is to be carried out in practice, as communicated to me by my
correspondent, I hereby claim as new and important features of the same:
1., The combination with the frames or chair-parts a and b and hammock c, of
an axle to which the hammock is attached, substantially as described, and means
for rotating the axle and keeping it in position, as and for the purpose specified.

page_text: 2. The combination with the frame or chair-part b, of the sliding frame k
having pivots m, means for rotatively locking the pivots m at the end of the
frame b when the frame k is drawn out, and legs o jointed to the frame k and
adapted to be adjusted and secured in respect thereto in the position required,
substantially as and for the purpose specified.
In Witness whereof I the said Carl Pieper have hereunto set my hand and
seal this thirty-first day of March in the year of our Lord One thousand eight
hundred and eighty-four.

On the annexed sheet of drawings Fig. 1 shows the chair with the extension of

In Fig. 2 the upper-part of the frame a is shown in section.
The two frames a and b are connected together at a in any known manner,
preferably by pins or pivots in combination with means for adjusting and
