SEGMENT GATE.

Application filed April 11, 1922.

T 0 all whom it may concern Be it known that I, THnonoR Bnci-inn, a citizen of Germany residing at Gustavsburg, Germany, have invented certain new and useful Improvements in Segment Gates (for which I have filed application in Germany April 28, 1920) of which the following is a specification.

My invention relates to well known segment gates consisting of two parts of which the upper segment leaf lies behind the lower and can be lowered under the upper edge of the upper retaining plate, but a constructional drawback lies in the fact that the supporting arms of both segment leaves which swing around the same pivot have to cross each other at the lowering of the upper segment leaf which causes difiiculties, especially in case of large segments and segments of broad spa-n because it is not easy to give the open frame of the bracings a sufficient carrying capacity.

It is possible to avoid this dificulty by adopting the Way which has already been suggested for old and small segments viz. that the supporting arms are placed beside each other and thus a crossing of each other is no longer necessary. This arrangement has, however, the great disadvantage that the two supporting arms owing to their breadth and position can no longer be placed in the cavity of the lateral masonry or pier and therefore the arms are subject to damage through ice or floating materials of any kind. Another way Would be to deepen the lateral cavities accordingly, but this would require a considerable increase of Specification of Letters Patent.

the breadth and thus increase immensely the costs of the masonry.

Following the invention these difficulties are avoided in such a manner that the upper segment leaf is journalled to swing on a special pivot arranged on the supporting arm of the lower segment.

The drawing shows such a segment gate in cross section. The lower segment leaf a is supported through its bracings 2) against the bearing 0 and can swing around the pivot (Z. The upper segment leaf e turns around the supporting arm f and the pivot g which is arranged on the lower segment leaf. As may easily be seen from the drawing the arrangement of the bracings of both segments do not interfere with each other therefore the bearing 0 as well as the bracings b of the lower segment can be made considerably simpler as under the usual arrangement. The slight difference of the curve radius of the upper and lower segment is of no importance to the operation and construction of the gate.

lVhat I claim is:

A segment gate consisting of two parts be ing arranged one above the other in such a manner that the upper segment leaf is journalled to swing on a special pivot arranged on the supporting arm of the lower segment leaf.

In testimony whereof I aflix my signa ture in presence of two witnesses.
