SPECIFICATION forming part of Letters Patent No. 490,010, dated January 1'?, 1893.

Application iiled July 16, 1892. Serial No. 440,264. (No model.)

To @ZZ whom t may concern:

Be it known that L JAMES MADISON Denn, a citizen ot the United States, residing at Harlan, in the county of Shelby and State of Iowa, have invented certain new and usefullmprovements in Loom-Shuttles; and I do hereby declare the following to be a full, clear, and exact description ot' the invent-ion, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to shuttles which are especially designed to be used in looms for weaving fabric. In handling this class of devices as at present constructed, preparatory to weaving, much inconvenience is experienced in manipulating the cop or can used for receiving the weft. When either the cop or can is used it is necessary to detach it from the shuttle body and place in the filling machine, and when filled and ready to replace, the wet t must be inserted through the shuttle eye, usually by tool called the shuttle hook.

The present invention obviates the inconviences above specified by discarding the use of inside attachment, the shuttle body being a plain tube.

The improvement consists of the novel features and the peculiar construction and coinbination ofthe parts which will be hereinafter more fully described and claimed and which are shown in the annexed drawings in which;

Figure 1 is a central longitudinal section of ashuttle embodying my invention. Fig. 2 is a detail view of the tension bar. Fig. 3 is a detail view of the shuttle head detached; the tension bar and spring being removed to the better show the structural arrangement of the said shuttle head. Fig. l is a detail View showing the manner of filling the shuttle. Fig. 5 is a detail View showinga modified forni of tension bar, and a set screw for regulating the saine.

The shuttle is composed, essentially, of the shell or body portion A which is hollow or tubular, being provided with the bore o, and the cap B, the latter closing the open end of the bore o and carrying the tension device. The shell or body portion A may be of any desired forni and size and is pointed at one end, the other end tapering slightly and being closed by the tapering head B. The shell or body portion A is hollow or provided with a bore a, the latter being closed at one end and open at the opposite end, the open end being provided with a depression or notch g in one side which is designed to receive the free end of the tension bar C. The head B for closing the open end of the shuttle body is made tapering, and is provided with a reduced portion b which is designed to enter the open end of the bore c and closethe same and give stability to said head. The notch ZJ provided in the inner end of the reduced portion Z) is adapted to receive and permit of the free workings of the tension bar C, and the transverse groove or channel b2, also provided in the reduced portions b is designed to receive the spring CZ which is pivotallyT supported between its ends, one end of said spring being adapted to press upon the tension bar C to create the desired tension, and the other end being constructed to obtain a bearing upon the inner side of the shuttle body A opposite the depression g so as to retain the spring in proper working position. The tension bar C is pivotally supported at one end at the inner end of the notch b and its outer portion is adapted to work in said notch b and the depression or notch g, and is preterabl y provided with parallel prongs c at its free end between which the weft thread is adapted to pass, said prongs preventing said weft thread from slipping from engagement with the free end of said tension bar C. These prongs c are adapted to enter suitable depressions j provided in the shuttle body. lVhile itis preferred to make the tension bar C and spring d in separate pieces, manifestly the two parts C and d may be integrally formed, as most clearly shown in Fig. 5. The operation will be precisely the same as that described for the parts when constructed separately.

The shuttle may be iilled in any desired manner but it is preferred to provide the means shown in Fig. 4 which consists of the tapering tube M the smaller end being constructed to enter the open end of thc shuttle body, and the drawing rollers N which are adapted to receive the weft thread and force the saine through the tube M into the shuttle body. VThe shuttle being filled in any desired manner, the end of the weft thread O is drawn across the depression g which practiyfm, serves to compensate for wear and maintain a tight fit between the cap B and the shuttle body A. This form of tension bar f dispenses with a separate springy and -embodies the same in its construction.

f Having thus described my invention, what I claim, and desire to secure by Letters Patent 1sl. The combination with a hollow'shuttle body open at one end, of ra cap adapted to close said open end, a tension bar, and a spring serving to secure said cap to the shuttle body, and create a tension on the saidftension bar substantially as set forth.

y2. The combination with a hollow shuttle body opened at one end, and having depression g, of a cap adapted to close the open end of said shuttle body, and a'tensiony bar oarried by said' cap and adapted to Work insaid Thetension bar shown in Fig. 5 ha'sa' depression gsubstantially as and for the purpose set forth. f

3. The combination withr a hollow'shuttle body, and a cap for closing the opened end of said shuttle body, of a tension bar carried by one of the said parts and provided with approximately parailel prongs b to give proper direction to the weft thread and retain the f same in proper position, substantially as described. f* ,c

4. The combination with a hollow shuttle body having one end open and provided with depression g, of a cap having a reduced portion to enter the open end of said shuttle body and provided 'with notch b and transverse channel b2, a tension bar pivotaliy con-
