T ll h it may Fig. 4 :s a-corresponding sectional view of Be it known that I, HENRY A. KENNEDY, the thri ad -guide, taken through its center; a citizen of the United States, residing at Fig. 5 is a top plan view of it; Fi 6 is a rovidence, in the count i and State of Rhode Island, have invented tial tub ilar eye and its porcelain threadcertai'n new and useful Improvements in guide positioned therein, disconnected from Thread Guides or Eyes for Loom-Shuttles, the shuttle; Fig. 7 is a perspective view rep of which the following is a specification; resenting; the secondary eye member and its he invention forming the subject of this porcelaii thread-guide, detached from the 10 application for patent relates more particushuttle; and Fig. 8 represents, in perspeclarly to improvements in thread-guides or tive, the relation of the initial and secondary eyes constructed for use in loom shuttles of eye members and their porcelain threadthe automatic and hand-threading types, guides,-s1bstantially as they appear when and it consists in the novel improvement arranged in a hand-threading shuttle, the 15 hereinafter set forth and claimed. shuttle body, however, not being shown.

The said metal eye members Usually, heretofore, in the construction of are permar ently fixed in the shuttle body, loom-shuttles the metal eyes of the shuttle, each eye mamber, m and m, havinga slot 30 when in use, were subjected to continuous s for the thread cut through its wall in wear by reason of the passage of the thread register with a, thread passage (5 formed in through the metal eyes, which not only inthe body A. creased the degree of friction. by wearing A. thread guide a of porcelain or other gr in h W l d mg h thread suitable nor. -metallic material is secured in 35 Itself, but at Same time Shortened i the thread-(utlet end of the respective eyes life of the eyes and caused an unevenness 1n tht thread-guides are practically the quality of the woven fabric, the result lik d h 11 d d ut r d being to add materially to the percentage of an open cenzral passage 0 and open slot 8 waste. By means of my improvement the extend longitudinally of the guide and are 40 loss or Waste referred to is practically'ehmiin pen o municati n with the said pasnated and the quality of the output imsage a and 8 Th outlet ends -0 of the proved. guides extem beyond the correspondin ends In the accompanying drawings Figure 1 of the metal ayes to protect the threa from represents a top plan view of portions of a chafing wear and friction as the thread is 45 hand-threading loom-shuttle provided with bent or defiec fed from the initial eye m into my improvement; Fig. 2 is a similar view of the secondary eye mand through its orceportions of an automatic threading-shuttle lain guides, which deliver the t read embodying my improvement; Fig. 3, is a smoothly from the shuttle to and between perspective view, enlarged of the non-methe harness shedded warps. The mouth 0 50 tallic or porcelain threa -gu1de itself, adaptof the slot 8 o::' the porcelain guide is rounded to be mounted in the delivery or exit end ed or flaring, is also the inner end a of the of a metal eye fixed in the shuttle body; central passage.

sents the relation of the assembled eye and guide elements, with the shuttle body omitted. In the drawings B indicates the slotted secondary metal eye m together with the slotted, secondary porcelain .threadguide fixed therein, and B indicates the assembled initial metal eye m having the longitudinally slotted wall and being provided with the slotted initial porcelain threadguide. See also Fig. 6.

seen that the protected first or initial nonmetallic slotted thread-guide member is mounted in and registers with the slot formed in the shuttle body and is adapted to receive into and guide the strand or thread of yarn as it is drawn direct from the cop or supply; the thread being bent or deflected at an angle from the projecting outlet end 0 of the guide, without coming in contact with the metal eye, the thread passes from the guide into the slitted and protected secondary nonmetallic guide positioned in the slitted secondary eye member 'm within the shuttle-body. The outer end of the last-named-guide extends through the eye m and through the adjacent outer side of the shuttle; the reciprocatory movements of the shuttle, as in weaving, causing the thread to render freely through and from 40 side to side across the mouth of the guide without wear and without engaging the metal eye, thereby increasing the efliciency of the shuttle and subjecting the thread to a more uniformdegree of tension or drag,

which acts to increase the quality of the woven fabric.

I claim,:- '1. The combination in a doom-shuttle, a

shuttle-body, means connected with the body By means of my improvement it will be located transversely for holding a limited amount of yarn, an opening cut in the shuttle-body for the passage of a strand of the yarn, initial and secondary tubular eyemembersfixed in the shuttle body, the said eye members being disposed at substantiall right angles to each other,'the walls of the eye members being longitudinally slotted and communicating with said yarn passage, a pair of non-metallic yarn-guide members having longitudinally slotted walls, the said non-metallic guides being secured in and projecting from the yarn delivery ends of the respective said eye members, the slots formed in the guide members being in open communication with the slots of the respective eye members, substantially as described, and for the purpose set forth.

2. In a loom-shuttle, a shuttle body provided with means adapted -for holding a supply of yarn, and a passage formed in the shuttle body adapted to receive the strand of yarn, the combination of an initial metal tube or'eye positioned to receive the. am direct from said supply, a non-metallic guide member secured within said initial eye and projecting from the terminal or outlet end of the eye, the walls of said initial eye and guide members being longitudinally'slitted and in open communication with each other and with said yarn-passage in the. shuttle:

body, a secondary metal eye member seated transversely in the shuttle body, a nonmetallic yarn-guide member secured within the secondary eye and extending from the outer end of the latter, and havingthe walls of said secondary eye and its guide member longitudinally slitted and in open communication with each other and with the said yarn passage formed in the shuttle body, substantiallyas described and for the purpose set forth.

In testimony whereof I have aflixed my signature in presence of two witnesses.
