Be it known that I, HUBERT LEOPOLD OF- renMANN, a subjectof the Kin of Saxony, residingat 2l Bismarkstrasse, Eeipzig, Ger-l many, have invented certain new and useful Improvements in Gill-Box Drawin Heads; and-I dohereby declare the fo lowing to be a full, clear, and exact description of the invention.

used in connection with fallers in textilev work, and more particularlyto fallers having two'rows of pins', the back row which is so much higher than the front row that back row still remains'therein, and in which the withdrawal of the fallcrs is accomplished insuch ii-manner that the pills iA are -lirst withthe pins of the the" front vand shorter row drawn andthe withdrawal of .21,2 hack row is o nly accomplished when, through ,.i.. the"fnr'ther 'progress of the faller, this row l1as `reached a o ilit corresponding to the j". point at which t itil front row was depressed. 1' idln this drawinglirocess an lauxiliar hainmer or cam is employed 'by means ot which thefallels` are pressed down on to their in- 4tei-mediate position in such a. manner as to allow the withdrawal of the front row of pins from the sliver. In the construction used heretofore, owing 'to the limited surface on whichlhe auxiliaryhaimnerhas t0 Work on the fallers, both are sub'ect to much weer, soA that the lowering of tie lallers is lmore or less uncertain, and as the auxiliariy hammer forms one piece with the gi l screw-being too smal to' be screwed or soldered'on to the sameit has been nee'essary, in the ease vof excessive wear to "replace this part by Athe expensive expedient 'of'an entirely new gill screw, '.llhisdisadvanta'ge fseek to overcome, by providing a lar e wearing surface, and by so connecting .t 'e auxiliary hammer that the latter is drivenby a set'of wheels-connectedwith the guiding screw., This the action of Vthemainlnnnmer and of tho' anxi iary lhammer onf-the fallersis accomplished alternatel and at thedeslred moment; Another isadvantage'is,that when t e aller sin': its -intermedlate position, the
