Application filed June 8, 1905. Serial No. 284,249.

To all whom it may concer-n,.-

Be it known that I, CHARLES E. NUTTING, a citizen of the United States, and a resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Im rovement in Loom-Shuttles, of which the ollowing description, in connection with the accompanying drawings, is a specification, like iigures on the drawings representing like parts.

This invention relates to loom-shuttles wherein the thread passes from the rillingcarrier or bobbin through a lon itudinal thread-passage and at the iront en thereof is turned laterally to the delivery-eye; and it has for its object the reduction of novel means for guiding the lling-thread at the point Where its direction di movement is changed.

My invention is particularly adapted to shuttles of the automatically-self-threading type in which the threading device or block is made of metal and is usually provided With an upright guide-pin adjacent the front end of the thread-passage, the filling-thread passing around such pin as it leaves the passage and enters the delivery-eye. In some instances the yarn or illin -thread appears to have a very destructive e 'ect on the metal guide, the constant travel of the thread thereover scorin or cutting into the nietalto such an extent t at in a comparatively short time the cuide is so roughened that it catches and brealis the thread. Such cutting action is particularly noticeable in using Woolen yarn, the ber of the` latter seeming to possess peculiarly destructive qualities. In order to obviate this wearing action upon the guide, I have in my present invention made the same rotatable, so that the friction ofthe yarn or filling-thread thereon is reduced to a minimum, and the cutting and scoring of the guide is thereby obviated, with consequent great increase in the useful life of the shuttle.

The novel features of' my invention will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure I is a top plan view of a loom-shuttldshowing the threading device or block of the automatically-solt-tlireading ty e, the guide being shown in dotted lines. Fig. 2 is a longitudinal section thereof on the 'line 2 2, Fig. 1, viewed from the side of the shuttle opposite that in which the delivery-eye is located, the thread-guide being shown partly in section. Fig. 3 is a partial side elevation of the shuttle from the delivery side, broken out around the delivery-eye to show the rotatable guide and the manner in 'which its of any suitable character, and herein I have illustrated the threading device as substantially that shown in United States Patent No. 769,914, granted September 13, 1904, to Northrop.

The block 6 of metal has a long fitudinalr thread-passage 7 and a narrow slit-like inlet 8 in its top, with a slot-like thread-entrance 9 at its rear or inner end, and at the front end of the thread-passage an inclined horn l() is formed on the undbr side of the enlarged head 11, which overhangs the entrance to the deliveryeye. The head is prolonged Jorward to form a beak 12, which crosses the front open end of the threadassage and is overlapped by a shield 13. W en the fillingthread is drawn into the thread-passage 7 and under the beak, it is directed automatically downward by the horn 10 and the adjacent parts of the threading-block into the delivery-eye. Urdinarily a steel pin is secured to the threading-block and depends adjacent the horn at the iront end of the threadpassage, the filling thread passing around this pin and under the heel 14 of the horn as it is drawn through the delivery-eye, and it is this guide-pin which is worn and scored,

as has been described. Y j

In accordance with my present invention mount on a depending pin 15, fixed in the threading-block adjacent the horn, an elongated rotatable sleeve 16, holding it on the pin by an enlargement or head 17 at the lower end thereof. As the filling-thread is delivered it draws around this sleeve and rotates it on the pin, the friction between the sleeve and the thread heilig thereby reduced to a minimum, so that the scoring and cutting IOO hereinbefore referred to is entirely obviated. The guide sleeve may be made of metal, Glass, porcelain, or other material suitable Ior the purpose. In order to prevent the thread from catching between the head of the pin and the adjacent end of the sleeveJ I provide a housing by forming a socket 18 in the shuttle-body, (see Fig. 3,) the lower end of the sleeve entering loosely therein, so that there is no possibility of the lower end of the sleeve or the pin-head being exposed.

My invention is not restricted to the par ticular form of threading device herein shown nor to the precise construction illustrated, as modifications may be made by those skilled in the art without departing from the spirit and scope of my invention.

Having fully described my invention, what I claim as new7 and desire to secure by Letters Patent, is

1. In a loom-shuttle having a delivery-eye and adapted to contain a supply of filling, a longitudinal thread passage, a rotatable thread-guide at the Jfront end of said passage and around which the filling-thread passes to the delivery-eye, and means to surround the lower end of the thread-guide and revent passage of the filling-thread thereun er.

2. In a loom-shuttle having'a delivery-eye and adapted to contain a supply of lling, a self-threading device provided with a longitudinal thread-passage, means to automatf ically direct the filling-thread from the pasand having a side delivery-eye and a longitudinal thread-passage, means to direct the illing-thread to said assage and thence from the front end thereoiD to the delivery-eye, including a horn, a depending pin adjacent the horn and having a head at its lower end, and

a sleeve rotatably mounted on the pin and around which the filling-thread passes as it is directed by the horn to the delivery-eye, the shuttle-body having a socket to loosely receive the lower end of'the sleeve and house the same and the head of the pin, to prevent catching of the thread between the head and the sleeve.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
