Description

AZEL C. HOUGH, OF JANESVILLE, WISCONSIN,
ASSIGNOR TO HOUGH SHADE CORPORATION,
OF JANESVILLE, WISCONSIN, A CORPORATION .OF CONNECTICUT.
METHOD OF REPLACING WEFT UNITS.
Specification of Letters Patent.
Original application filed December 31, 1906, Serial No. 350,116. Divided and this application flled septemb er Serial No. 896,105.
To all whom it may concern: Be it known that I, AZEL C. HoUGH, a citizen of the United States of America, residing at Janesville, in the county of Rock and State 1 units,
of Wisconsin, have invented a new and useful Method of Replacing Weft Units, of which the following is a specification, the same being a divisional part of an ap lication for United States Letters Patent" ed by me December 31, 1906, and numbered Serial No. 350,115
My invention relates to improvements in methods of replacing weft units in woven shades and the like the fabric of which has a weft of more or less substantial material as wood, andconsists broadly in automatically or mechanically extending, drawing out or opening the warp on one side of the weft unit which it is designed to replace and in" passing the new unitthrough the openin s thus formed, in juxtaposition with the o (1 unit, before'removin the latter, as will be more fullyexplained ereinafter.
The object of-my inventionis to provide a method of replacing broken, defectlve or .imperfect slats already'woven in shades of the class above mentioned with perfect ones,
work which has been done-heretofore by hand, or for other similar urposes, whereby a large saving in time, la orpmaterial and expense'is efiected. The slats whether. per-. feet or imperfect,-to which my invention relates, are termed herein weft units or simply In carrying 'out my invention the mechanism whichlforms the subject matter'of the aforesaid application may beemployedto advantage, and in the accompanyin drawmg I show such portions of'said'mec anism 1 for as are deemed necessary or desirable for a clear understanding of the herein described method, but itisobvious that I am'not limnears the use of any particular mechanism utting's ich invention into practice so far e scope of the present application is conast Said idrawing represents a section of a r shade resting upona-table and a weft unit beingintroduce with arts into the shade by means of a needleof eculiar construction, together of an abutment mechanism designe' to revent the new weft unitfrom bucklingw hilebeing inserted.
r Before describing the meth d as rendered eifet'ztive the help of the mechanism s .one end oft illustrated, I will describe the same in detail Patented April 28,1908.
without reference to any specific mechanical,
aids. First the shade must be so placed that the defective weft unit is in a convenient position and then while such shadeis held in this position the loops of the war on one side of the defective unit are force away from said unitrand the new unit is thrust throu h the loops thuso ened until it lies along the e 7 tire length of t e defective unit between thev latter and the warp. The warp loops are opened or read successively be inning at e defective unit. T e perfect 'unit is forced or driven in to the shade, as statedfhence it must be so held to its course in advancin that it cannot buckle, otherwise it would be 'able to break or in any event to interfere with the complete success of the op eration; this guarding against buckling con stitutes one of the important steps in the method,"alth ough it is not to be considered-as indis ensiblein all rcases. Asa final step the o 'd unit is removed from the shade, leaving the new unit in its lace. It is usual, in practice, to place the s ade on a table with the defective or imperfect weft unit uppermost and to superim ose the new unit on such imperfect or de ective unit,- although this arrangement is not imperative so far as the broad idea ofthe invention is concerned, Referrmg nowto thedrawing it will be ob-v served that a portion of a shade 1 is there represented, and that such shade is sup- 1 ported on a table 2, being fastened or" clam ed thereto by some suitable means Whic does not a'pear in-the illustration, with a defective s at ,3 on top of said table. A needle 4, so constructed thatit -can be forced along on top of the slat 3 to open the war 5 for the entrance of a slat 6 which is to rep ace finally fsaidslat 3', is employed by insertin its point or bill 7 beneath the loop.
in the st hne of Warp which is above the imperfect slat, at one end, and by forcing it forward through the, medium of the slat 6,
ice
the front terminal of which latter is received into a socket 8 at the end of the needle opposite said bill. Theslat 6 may be forced or which are not herein shown, or by any-other driven forward by means of friction wheels suitable means. As the needle 4 is thus j driven forward on the slat 3 its point enters" g" beneath the second warp loop before the body 9 of said needle, passes from beneath the first loop and while such body is subjected to PATENTED APR. 28, 19 08.
