To all whom it may concern.' 1 'Be it. known that I, CHARLES H literaire;-v BERGER, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Tarp- Knitting'Machines, of which the following is a specification.- nl.
The object of my invention is lto provide y for the production of knitted. fabrics of the' structural character shown and' described. in my application for patent, filed September 24, 1888, Serial No. 286,148, and especially for the" production of such .fabrics witha figured or patterned face, andthis object I attain in the manner hereinafter set forth, reference j being. had to the accompanying drawings, in
which- Figuresl, 2, and 3 are diagrams illustrating the operation of the machine; Fig. 4, a transverse section, partly in elevation, of part of the machine; Fig. 5', a .longitudinal sec-` tion, partly in eievation; Fig. 6, a transverse Esection of the Jacquard apparatus on an en` larged scale; Fig. 7, sectional pla of the' same,landFigs. i'S-to 2O detached views illustrating features'oftbe invention.
The fabric shown in Fig. 1 of the application above referred toconsisted of a backing constituting in itself fai complet-e fabricand having a series of tufts` or loops tied down or secured thereto by binding-threads forming r rows of stitches, andthe fabric was produced the main feature of the machine is its prof, rvision for the production ofiigured or patset forthinthe application noted."
The general operation of the machine will terned fabrics of astructure similar to that I' -be understood from the diagrams, Figs. 1 to 3, in Whh represent opposite g'uide'i` plates, over which are drawn inthe direction Applies@ filed August- 13, 198'?.`A stm-ai ro. 246,848. (remodel.)

(See Fig. 1.) the guidesw are moved transversely and longitudinally so as to wrap the-selected threads aroundsaid need1es,as shown in Fig. 2, andthe needles then descend so as to draw their stitches through the backing fabric and through previously formed on the needles.
As-shown in the drawings, special needles constructed inthe manner described hereinafter are used in the machine, but ordinary be employedin needle; S
After the needles at the front o f the machine have completed their descent those on the place of the'specal form of back of the machine rise and the thread-l arness-threads guides w are shifted and theh operated so asto draw the unused warpthreads out of the way of the'rising needles,
