Improvements in Adjustable Sectional Pipe Bends.
We, CARL LUDWIG LAUBSCH, Tinner, OSCAR EMIEL UHLE, Grocer, and RUDOLF
BRÜGGEMANN, Machinist, all of Norfolk, County of Madison, Nebraska, U.S.A.,
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 pipe bends which are more especially designed for
application to stove and other smoke conveying pipes.
In the accompanying drawing Fig. 1 is a sectional view of the adjustable pipe
bend of the invention. Fig. 2 a side elevation. Figs. 3, 4, 5, refer to details.
A are a number of metal sections in any suitable number preferably formed from
blanks having a straight and a curved edge as shewn in Fig. 4 so as to form a cylinder
longer at top than at bottom in order to permit the sections to be adjusted to various
angles or degrees of curvature. The end section A¹ is preferably formed from a
substantially rectangular blank as shewn in Fig. 5 while the end section A is formed
somewhat like the intermediate sections but wider as shewn in Fig. 3. Each section
beginning with the end section A2, overlaps and is pivotted to the next adjoining
section on opposite sides thereof transversely to the plane of curvature as at a, thus
permitting the sections to be adjusted independently of one another. The sections
may have an offset a' at the top edge to partly surround the circumference in order
to allow the edges of the overlapping sections to receive the sections next to them
without binding and so that the angle of curvature of the several sections may be
varied as desired.
b are two levers by which in conjunction with a screw bolt Cand a wing nut c, the
sections when adjusted may be rigidly held in position. These levers are pivotted
each at one end on the inside of the end sections as at and their requisite
movement is allowed by means of a slot 62 in each of them.
Assuming the parts to be in the position of Fig. 1 it will be obvious that if the
nut c is released any or all of the sections may be moved or tilted upon their pivots so
This
as to cause each overlapping section to slide upon its adjoining section.
movement will cause the levers b to slide upon one another and upon the bolt C,
whereupon the nut may be tightened to hold the levers and with these all the sections
in the adjusted position.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. A pipe bend comprising a series of independent sections, each pivotted to the
next adjacent section so as to be independently adjustable, and means for holding the
sections in an adjusted position whereby the bend or pipe section may be caused to
assume various angles or degrees of curvature, substantially as described and
shewn.
2. In a pipe bend, the combination with a series of independent sections pivotally
secured together, of a pair of levers arranged within the bend and pivotted each at
one end to an end section and each provided with a slot at its other end, a bolt for

sections, and levers whereby the pipe bend may be adjusted and held at various angles
or degrees of curvature, substantially as described and shewn.
3. The general construction, arrangement and combination of parts constituting
the pipe bend, substantially as described and shewn,
