FRIEDRICH CARL GLASER of Berlin in the Kingdom of Prussia and Empire of
Germany, Engineer and Patent Agent. "IMPROVEMENTS IN APPARATUS FOR
DARNING FABRICS, AND FOR PRODUCING A RUNNING STITCH THEREON." [Communi-
cated to him by Mr Emilie Weiss, a person resident at Breslau, in the German
Empire.]
This invention relates to an improved construction of apparatus that may be
used either for darning fabrics or for producing a running stitch thereon. The said
apparatus and its mode of operation will be readily understood on reference to the
accompanying drawings in which Figs. 1 to 5 shew various views thereof while
Fig. 6 shews the same in operation..
The apparatus consists of a trough shaped plate a the sides b and c of which are
formed with serrations as shown, the serrations being narrower at bottom than at
top. In these serrations are placed a row of needles as shewn at Fig. 6, so that the
eyes thereof are situated just beyond the one side, while the needles project in a
parallel row beyond the other side. The needles are clamped firmly in this position
by means of a plate d hinged to a at c, and provided on its underside with an
elastic surface i of caoutchouc or other material, so as to bear with an elastic
uniform pressure on all the needles, when turned down upon them from the
position shewn in Fig. 1 into that shewn at Fig. 2, in which position it is secured
by a stirrup f hinged to a and having either a set screw g as at Figs 1 and 2, or a
cam lever has at Fig. 2. The needles may also be prevented from shifting
longitudinally in the serrations, so as to keep all the points in a line by a bar p
hinged at z which is turned down so as to lie close against the projecting eyes of
the needles, as shown at Fig. 6, the free end of the bar being also held by the
stirrup f. For operating with this apparatus, two such are required, and they are
worked as follows. The needles being all threaded and fixed as described, they are
manipulated by the hand for the purpose of darning or running the fabric in
precisely the same manner as is, now practised with a single needle, all the needles

shewn. When a sufficient number of such folds have been placed on the needles,
the points thereof are secured in the serrations of the second apparatus; the first
apparatus is then removed from the needles, which, with their threads, are drawn
completely through the folds k, l, m, n. The needles are then pushed through the
second apparatus, until they occupy the same position therein that they did in the
first apparatus and a further set of folds are then passed on to the needles, and so
For conveniently and rapidly threading all the needles simultaneously, the
thread is attached to one end of a fine wire, which, together with the thread is
passed through all the eyes of the needles; a loop of thread is then drawn out from
the reel to the required length between each two needles, and such loops are then
cut through, thus forming a length of thread for each needle.
