I, KASPAR FREULER, of 120, Birmensdorferstrasse, Zürich, Switzerland, Physician,
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 :-
This invention relates to an improved collapsable stretcher, the sides and ends of
which are formed in lazy-tongs fashion and secured to four posts.
And in order that my invention may be more fully understood I have caused to be
appended hereunto one sheet of drawings, marked with letters of reference indicating
like parts in the various figures, showing one form in which my invention may be
carried out.
Fig. 1 is a side view, Fig. 2 a plan, Fig. 3 an end view, and Fig. 4 a cross section
of the stretcher when extended. Figs. 5 6 are a side view and plan respectively of
the stretcher when collapsed, and Figs. 7, 8, 9 & 10 details at an enlarged scale.
In carrying out my invention and referring to the figures generally, a¹ & a² are
the sides, the head and 62 the foot of the stretcher formed of lazy-tongs links c,
the outer lower ends c¹ of which are articulated to the posts d-d, whilst the upper
ends c² are secured to the posts did when the stretcher is extended by means of
removable pins e. The upper joints of the lazy-tongs links at the sides a¹ & a² are
furnished with slotted eyes f, which serve for the reception of the thickened
edges g¹ & g of a stretcher canvas g or net g and permits the latter of sliding therein.
The canvas or net g is secured to the head by the eyes g³ & g', which are hooked
onto the pillars h³, h² and straps and buckles h³ and to the foot 62 by straps and
buckles only, the said pillars being rendered vertically movable.
The sides a & a² are stayed by means of the tongs i and pins which prevent
the sides a¹ & a being drawn together when the canvas gor net 95 is weighted.
The tongs are retained in an extended position by means of the hook 2. Into the
posts did are secured in bayonet joint fashion the handles -4. The
projection of the handles & also retains the pillars h¹ & h² in their upper
position, which causes the canvas or net to incline from the eyes f¹ & f² to the
head b¹ so as to serve as a pillow.
After having removed the pins e, handles ¹-k, pushed down the pillars h¹ & h²
and removed the hooks the stretchers can be collapsed to the size of a military
knapsack by pressing same together lengthwise and sideways and being made
comparatively light material it is very suitable for military and similar
.
purposes.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim, is :-
1st. A collapsable stretcher, consisting of a frame formed of lazy-tongues a¹, a², b¹, b²,
the lower ends c¹ of which are articulated to posts d'-' and the upper ends c²
secured to the posts - by means of removable pins e, all substantially as set

page_text: 2nd. In a stretcher such as specified in the preceding claim, a cross stay for the
stretcher, consisting of lazy-tongs placed on pins ¹ and retained in an extended
position by a hook 2, all substantially as set forth.
3rd. In a stretcher, such as specified in Claim 1, the canvas g or a net g
formed with thickened edges received by slotted eyes, all substantially as
described.
4th. In a collapsable. stretcher such as specified in Claim 1, the slotted eyes f
employed at the upper joints of the lazy-tongs links adapted for the reception
of the thickened edges of the canvas g or net g³, all substantially as set
forth.
5th. In a stretcher such as specified in Claim 1, the pillars ¹, rendered
vertically movable on the posts d', d of the head band which in their upper
position support the said canvas or net at an incline so as to serve as a pillow,
all substantially as set forth.
6th. In a collapsable stretcher such as specified in Claim 1, the handles -k
placed into the posts d'-d and secured therein in bayonet joint fashion, all
substantially as set forth.
Dated this 18th day of May 1899.
