nitiattant' PETTER BERGQVIS-T, OF AUSTIN, MINNESOTA.
Letters Patent No. 112,010, dated February 21, 1871.
IMPROVEMENT IN PORTABLE WATERCLVOSETS.
The Schedule referred to in these Letters Patent and making part of the same.
Tolcll whom 'it may, concern Be it known that I Pnr'rnn BERGQvrs'r, of Austin,
in the county oi' Mower and in the State of Minnesota, have invented a new and useful Improvement in Portable Water-Closets; and I do hereby declare the following to be a i'nll, clear, and exact description ofthe saine,A reference being had to the accompanying drawing making a part of this specification, in which- Figure l is a perspective view.
Figure 2 is a vertical longitudinal section.
Figure 3,`a perspective view.
The same letters of reference, where employed in the several figures, indicate identical parts.
The nature of my invention relates to the construction of portable water-closets from which no disagreeable odor can escape into the rooms in which they are placed. i
To enable those skilled in the art to make and use my invention, I will proceed to describe its construction and operation. Y
Av in the drawing refers to a rectangular box made 0i' wood or any other suitable material, and employed as a casing for the receiver E.
B forms the top part or seat, constructed in the ordinary manner, and hinged to thebox.
A'is a door, through which the receiver is placed und removed.
A is a rectangular-formed box, serving as a cover' for the receiver G, and also as a footstool for the person occupying the seat B.
A is secured. to the box A by means ot' hooks or my other suitable device, and is on one of its sidesV provided with a door A', through which the receiver G -may be placed and removed.
(l is a cover or lid, hinged to the box A, and is at its center provided with a projection itting'into the aperture in the seat B.
Said projection is covered with India rubber or some other elastic material, C', which extends entirely or partly over the lower' surface of the lid C, so that whena the lid C is closed the elastic material will rest between the lid and the seat, forming an air-tight joint, and preventing any odor from escaping.
D is a pipe, which, at one end, is inserted in one of the vert-ical sides ofthe box A, at a height between the top of the receivervEand the seat B,and leads into a chimney or ventilator, throughjwhich the odor arising from the receiver E will escape.
E is a receiver forv the excrements. It is provided, at 0r near its upper edge, with a cover, which consists of two or more parts.
Fig. 2 in the drawing represents the cover, consisting of two parts, E and E' is hinged to the inner s ide of the receiver, and, when no weight is resting upon it, it is kept in a horizout-a1 position by n'ieans of a spring,
As the springE" has only tension enough to keep the weight ot' E in a horizontal position it will allow ll' to assume a downward inclined position when any ranged that it may revolve on a pivot at its center,
and balanced so as to occupy a horizontal position in the same level as the other part of the cover E'.
`E' and do almost touch each other when in aA horizontal position, andform a nearly airtight cover i'or the receiver E.
The dotted lines in iig.,2 indicate an inclined po-l sition of the parts and E'", which they will occupy when discharging any weight which mty rest upon then.
When relieved of the weight they will immediately assume the horizontal position, shown in full lines in d". 2.
DF is a vertically-placed tube, provided for the purpose of conducting. the urine into the receiver G;
At its upper end it is -secnred to the lower surface of the seat B, at or near the front of the aperture in the seat.
It is provided with'a mouth or funnel, which extends far enough'over the. receiver E to collect the lll'llle.
At its lower end the tube F is bent suliiciently to discharge its cont-ents into a receiver, G, which is placed inside the closed box or footstool A.
The receiver G is provided with au air-tight cover,
and the box A', in which it is placed, is provided with a metallic or India-rubber lining, A, as shown in tig. 2.
Figure 3 represents a portable water-closet constructed like a chair, but any other suitable forni may be adopted.
The operation of' my invention is easily understood, and does not require any lengthy description.
The excrementtious matter and the urine are separated and discharged in separate receivers, E and G.
-The receiver G is entirely air-tight, and any disfrom the tube F and the receiver E into a chimney V or ventilator.
When not in use, the cover C ought to be closed, thus forming a neat looking piece of furniture, which may serve as an ornament in a room.
Having thus described my invention, In testimony whereof I have signed my name to Wham I claim, and desire to secure by Letters Patthis specification in. the presence of twosubscribing ent, iswitnesses.
The combination and arrangement of the frames or boxes A and A, lined oyer 4C, receivers, G and E, the latter-provided with a lid. consisting of the two Witnesses: parts E' and E, tube F, and air-pipe D, substantially l J. S. IRGENS, as and for the purpose set forth.
