of the German Empire, residing at Gotteninve'nted new and use- Improvements in Weft-Re lenishing ing is a specification. i

My invention relates to improvements in weft replenishing mechanism for looms with weft forks, and has for its object to simplify l echamsm for Looms, of which t e foll0w applicable to looms -with over pick or under pic or fast or loose reeds.

My nnproved mechanism is fixed atone cop or the like.

side of the loom frame and consists chiefly of a pirn, cop or the like magazine in connection with acarrier or slide which when the slay moves forward conveys a pirnjcop or thelike from'the magazine into the shuttle each time a weft thread breaks or the im, cop or the like is spent, the empty spin e or the pirn, cop or the like with broken thread being dischargedthrough an opening in the wall of the shuttle box and of means for g'uiding the pirn, cop or the like accurately into the shuttle and for adjusting the latter. I attain these objects by themechanism illustrated in the accompanying two sheets 'of drawings, in which Figure 1 is a side view partly in section of a loom provided with my improvements, and Fig. 2 a detached plan showing the position of the operating parts of the mechanism be-- i fore the changing of the pirn,'cop or the like. Fig. 1 and Fig. 2 are respectively adetached side view and a plan of a pirn or the like carrier or slide. Fig; 3 is a side view partly in section, and Fig. 4 a plan,. Fig. 5 a front view detached showing the position of the parts during the changing 'of the pirn, Fig. 6 a detached back view? Similar letters refer to similar parts throughout the several views.

In carrying out my invention and referring to the figures generally, I fix to one end of the weft fork rod a a lever a, while the other end hasas us'ualsecured an arm'bearing against the weft fork-slide. To the bracket '1) fixed to theloom side, I fulcrum an arm I) suspended, say bya spring from the lever a and e in the free end of which carries an anti-friction roller, points downward and descends and rises in unison'with the lever a.

In the lay I mounta vertical shaft i to the the bottom end anose It and a lever 7c, the

latter being connected by a spring 0 to the lay. As the lever 6 1S raised its roller comes into the path of the nose 7: causing the shaft i to turn and the finger ito bring the shuttle into its correct .position in the box while when the lever b descends its roller comes out of the path with the nose k'and permits the spring 0 to turn the shaft i and bring the finger out of the path of the shuttle.

The part of the arm I) carrying the antifriction roller is hinged to and under themfluence of a s ring on the part of the arm 6' secured to t e weft fork shaft (1 so. that should owing to the breakage of a driving partly enters the shuttle box that the finger i when moved inward presses against the side of the shuttle the roller end of the lever b is allowed to vent damage.

0 is the ratchet pawl of the taking up mospring. I

At the front end of the loom frame and in front of the cloth beam I secure to a pin n, an angular arm e to the free end of which I pivot at its free end suspended from the lever a by a spring. To the pin 11, I also secure an arm f the free end of which is connected to a carrier or slide g.' h is a hinged finger which which holds the lowermost of, the pirns or the carrier or slide brings it into the'shuttle when. it will be raised out of theway by the for- Ward moving pirn or the like and drop into its normal position again on the return of the carrier or slide.

To the lay sword I secure a stud Z or I make use of the stud already existing thereon i which in'the usual manner actuates the pawl of the ratchet wheel 65. When the lay moves forward, the stud Z engages in the forked end of the arm cl (as shownin Fig. 3,

top end of which is secured a finger i and to belt or picking strap, the shuttle only so yield sidewise and thus pre t ion suspended from the lever a, say by a the arm d pointing towardthe lay swordand' like in position in the guides until the said bears against the side of and the weight of and spring connected therewith.

with arm'cl raised) by means of the lever a I The taking up and letting off motion is acpawl c. When the latter is raised the taking catch or pawl disengages from the ratchet the latter to turn back as far. as the expansion catch permits.

On the carrier or slide g I pivot a lever m one end of which is forked while to the other end I connect a spring m secured to the slide g the said forked lever being adapted to guide into the shuttle, pirns or the like only partly full and-thereby prevent same fromfbeing trapped at thetip through not entering the shuttle as readily as necessary.

Normally th'elever m is pressed against the front ed e of the support 9 of they carrier or guide 9 butwhen the latter moves forward, the spring m causesv the forked end of the lever m to advance and carry the tip end of the pirn or the like ,to the shuttle while on the return movement of the carrier or slide 9 the lever m resumes its normal position.

a is the magazine from which the pirns or the like gravitate in front of the carrier or slide 9 one by one.

'u, are channel sectioned rails which guide the pirns or the like horizontally to the shut tle. Both of'the said rails are under the influence of aspiring and so mounted as to recede in case of a picking stra or the like breaking if some object shou d come be- As will be seen from Fig. 6 the pirns or the like rest in the magazine upon each other and the loose thread ends are placed round the back of the magazine toward the warp and there gripped between the coils of a spring i The weft replenishing mechanism de is spent or the weft fork drops, the latter is way and the weft fork slide then being ceives a turn and raises the lever a and arm b and also the pawl c and arm (Z by springs connected with the lever a. On the return movement'of the weft hammer the weight of the said parts causes them to returnto On the forward movement of the lay, the taking up motion sword engages with the forked end of the rier, or slide g forward. The fin er it turns and frees the path toward the siuttle, and the nose k' havingat the last moment come into contact with the arm I), the finger i receives a. l of a turn and brings the shuttle into its correct position for receiving the scenes pirn or the like, Figs.-3', 4 and 5, which is then pushed into the "shuttle by the carrier,

or slide 9 and held fast therein by a spring.

When the shuttle carries the weft through,

the shed, the weft is in the selfthreader and its end is tensioned between the spring i and the warp side. While the carrier or slide 9, pushes a pirn or the like into the shuttle the other pirns or the like in the magazine a rest upon the carrier or slide. As soon-as the lay is moving back, the lever a begins to descend and causes the nose is to lose contact with the arm the springo causing the shaft i to turn and move back the finger i and release the shuttle, the pawl c then being in gear again with. the ratchet wheel, the arm d lowered, the carrier or slide 9 moved back and fresh pirn or the like will drop in front of the carrier or slide. During weaving, the said weft end remains tensioned l when it reaches the temple is torn at the sclvage of the fabric by the temple cover which dispenses with the necessity at a me chanically operated cutter.

I claim:
