ALONZO R. PATTEN, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR TO THE KNOlVLES LOOM WORKS, OF WORCESTER, MASSACHUSETTS.

LOOM.

SPECIFICATION forming part of Letters Patent No. 580,143, dated April 6, 1897.

Application filed November 28, 1896. Serial No. 613,808. (No model.)

T all whom it may concern:

Be it known that I, ALoNzo R. PATTEN, a subject of the Queen of Great Britain, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Looms, of which the following is a specification, reference being had therein to the accompanying drawings.

IO The invention relates chiefly to the protector mechanism of looms, more particularly to the protector mechanism of looms having applied thereto automatic weft-replenishing devices on the order of those which are pre I 5 sented in United States Letters Patent to James H. Northrop, Nos. 529,940 and 529,942, granted November 27, 1894, and to F. M. Day, No. 552,35at, granted December 31, 1895.

The nature and objects of the invention will first be explained clearly in the following description,forming part of this specification, in which description reference is had to the accompanying drawings, and afterward the distinguishing characteristics of the invention will be particularly pointed out and distinctly defined in the claims at the close of this specification.

Figure 1 of the drawings is a view in end elevation of certain portions of a loom having my invention applied thereto, sufficient of the loom being shown to render clear the character and relations of the invention. Fig. 2 is a view in front elevation of the lay and certain of its appurtenances, some of the parts that are shown in Fig. 1 being omitted from Fig. 2 for the sake of clearness. Fig. 3 is a plan View of the lay, omitting some of the parts that are shown in Fig. 2.

1 1 designate the lay-swords, and 2 designates the lay-beam.

3 is the shuttle-box at the left-hand end of the lay. 4 is the shuttle-box at the righthand end thereof, and 5 is the shuttle, herein shown as occupying the shuttle-box 3.

The weft-replenishing devices herein referred to are, in the case of the loom which is shown partly in the accompanying drawings, located chiefly adjacent to the left-hand shuttle-box 3. The saidweft-replenishing devices comprise in part the stand 6, Figs. 1 and 2 which is mounted upon the breast-beam 7 of the loom, parts of the said stand being represented as broken away in the said figures for the purpose of showing parts which otherwise would be concealed, the rotary bobbin-holder 5 5 8,which' is supported by the said stand, the weft-supporting disk 9, weft-holder 10, and ratchet 11,which are connected with the said rotary bobbin-holder, the retaining-pawl 12 for said ratchet, and the actuating-pawl 13, the pawlcarrier 14, the pusher 15, the arm 16, the tip-supporting device 17 for the bobbin which is being inserted into the shuttle, and the swinging chute 18, which forms a bridge below the lay, by which the bobbin which is expelled from the shuttle will be conducted away from the lay, as in the case of bobbin 19 in Fig. 1. These parts and their working, as well as the other parts which are connected in operation therewith, are all described fully in the patents which are mentioned at the outset herein. The said \veftreplenishing devices interfere with the use of the ordinary protector-shaft extending entirely across the loom on the front side of the lay-beam and having at the opposite ends thereof upwardly-projecting protector-fingers engaging with movable shuttle-binders at the fronts of the shuttle-boxes. Such arrangement of protector devices and movable shuttle-binder at the front of the shuttle-box has been found inconvenient at the weft-replenishing side of the loom, because of the presence and movements of the parts which are employed for introducing a fresh bobbin into the shuttle and disposing of the exhausted bobbin. Hence at such side of the loom the movable shuttlebinder is placed at the rear side of the shuttle-box 3, as at 20, Figs. 1 and 3, and the protector-finger 21, which coacts therewith, is 0 mounted upon a protector-shaft 22, that is supported in bearings at the rear side of the. lay-beam. Customarily when the protectorshaft is mounted at the rear side of the laybeam the loom is arranged to protect, as it 5 is termed, at the side of the loomthat is to say, the dagger which is carried by the protector-shaft is caused to engage with a frog or bunter that is located at the side of the loom.

A large number of the looms which at present are in use or are being manufactured have the protector-shaft and binders of the shuttle-boxes located at the front of the lay-beam and the loom protects at the front or center, as it is termedthat is to say, the dagger carried by the protector-shaft engages a bunter or stop-motion device that is applied to the breast-beam, the engagement taking place at an intermediate point in the width of the loom.

The chief object of the present invention is to facilitate the use of weft-replenishing devices of the character hereinbefore 'explained in connection with looms of the class using a front or center or, as some term it, a breast-beam protection, and to obviate as far as possible the necessity for changes or alterations to fit such looms for having applied thereto the weft-replenishing devices. To these ends, while mounting at the rear side of the lay-beam the shuttle-binder 20 of the shuttle-box 3, that is adjacent to the working parts of the weft-replenishing devices, and similarly mounting the protector-finger 21, which coacts with the said shuttle-binder, as well as the protector-shaft 22, on which the said protector-finger is made fast, I leave the shuttle-binder 23 of the opposite shu ttle-box 4 at the front side of the lay-beam, as well as the protector-finger 2%, which coacts with such shuttle-binder 23 and the protector-shaft 25, on which the protector-finger 24 is made fast. Upon the front protector-shaft 25 is carried the usual dagger 26 in the customary position, namely, at an intermediate point in the width of the loom, the said dagger engaging, as heretofore, abunter or stop-motion device 27, that is applied to the breast-beam 7. To the rear protector-shaft 22 I make fast a forwardly-extending arm 28, and to the front protector-shaft 25 I make fast a rearwardly extending arm 29, one of the said arms being forked or slotted and receiving a portion of the other arm, so as to compel the two protector-shafts to rock in unison and operate as a single shaft.

By making use of the foregoing arrangement and combination of parts Iam enabled to apply the weft-replenishing devices aforesaid to either new or old looms of the style referred to with a minimum of changes or alterations and without interference with the protecting devices at the opposite end of the loom or with the daggers, the hunters, and the stop-motion devices which are actuated through the agency of the daggers.

I claim as my invention 1. In combination, the lay of a loom having shuttle-boxes at the opposite ends thereof,

the shuttle-box at one end of the lay having its shuttle-binder at the rear side thereof, a protector-finger coacting with the said rear sh Little-binder, and a rear protector-shaft carrying the said protector-finger, the shuttlebox at the opposite end of the lay having its shuttle-binder at the front side thereof, a protector-finger coacting with the front shuttlebinder, a front protector-shaft carrying the said protector-finger, a dagger also carried by the said front protector-sh aft, a hunter or stopmotion device engaged by the said dagger,

and connections whereby the front protectorshaft is operated from the rear one, substantially as described.

2. The combination with the weft-replenishing devices located adjacent to one end of the lay of a loom, of the said lay having shuttle-boXes at the opposite ends thereof, the shuttle-box which is adjacent to the saidweftreplenishing devices having i ts shuttle-binder at the rear side thereof, a protector-finger coacting with the said rear shuttle-binder, and a rear protector-shaft carrying the said protector-finger, the shuttle-box at the opposite end of the lay having its shuttle-binder at the front side thereof, a protector-finger coacting with the front shuttle-binder, a front protector-shaft carrying the said protector-finger, a dagger also carried by the said front protector-shaft, a hunter or stop-motion device engaged by the said dagger, and connections whereby the front protector-shaft is operated from the rear one, substantially as described.

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

ALONZO R. PATTEN.
