Patented Sept. 24, 1929 UNITED STATES PATENT OFFICE FRANCIS E. ASHTON, OF CHESTER, PENNSYLVANIA, ASSIGNOB. TO ABERFOYLE MANU- FACTURING COMPANY, OF CHESTER, PENNSYLVANIA, A CORPORATION OF PENN- SYLVANIA SHUTTLE Application filed December 5, 1928. Serial No. 323,817.

This invention relates to weaving and more particularly to an improved shuttle which is particularly adapted to the form of loom shown and described in my application executed and filed on even date herewith, Serial No. 323,818.

In the loom above referred to, weft thread from a cone is looped over the pin on the shuttle and passed through the shed of the warp into a shuttle receiver and is then returned to a shuttle receiver on the initial side on the succeeding pick. It is necessary to then remove the loop of weft thread from the shuttle and to place a new loop thereon for each successive pair of picks.

The shut-tle herein described is so arranged that the loops of the woven wefts may be discharged and new loops to be woven received by the pin automatically and without severing the weft thread at any time.

One of the objects of my invention, therefore, is to provide a shuttle which has means for receiving and discharging a loop of weftthread.

Another object of the invention is to provide a shuttle which may be automatically operated for receiving and discharging a loop of weft thread.

he shuttle which comprises my invention is in outer configuration identical with the shuttle used in the present day looms. It has a lever operating in a slot, the slot terminating in a transverse channel and that end of the lever being provided with a pin. The other end of the lever is depressible for raising the pin to discharge the loop of the woven weft from the pin and to receive thereon a new loop of weft to be woven.

The discharge of the loop of weft thread may be assisted by a shoulder formed in the channel while the pin may be normally held in. its lowered position by means of a spring acting to raise the other end of the lever.

If desired, each end of the shuttle may be provided with a thread receiving and discharging pin, each on the outer end of a pivoted lever, and the other ends of the levers may slightly overlap at a point in the center of the shuttle so that both ends may be depressed in the manner just above described.

The drawings illustrate embodiments of the invention and the views therein are as follows:

Figure 1 is a front elevation of the shuttle,

Figure 2 is a top plan view,

Figure 3 is a longitudinal section on the line 33 of Figure 2,

Figure 4 is a crosssectional View on the line 1-4 of Figure 2, looking in the direction of the arrows,

Figure 5 is a front elevation of a double ended or universal shuttle,

Figure 6 is a top plan view of the same,

Figure 7 is a longitudinal section on the line 7-7 of Figure 6, and

Figure 8 is a cross-sectional view on the line 88 of Figure 6, looking in the direction of the arrows.

ljigures 1, 2, 3 and 4 represent a shuttle which may be used for weaving the weft into the cloth on a machine such as that described in my application for loom, above mentioned.

That particular loom therein shown is what is known as a left hand loom; and for use with a right hand loom, the entire mechanism of Figures 1, 2, 3 and 4 would necessarily have to be reversed or the shuttle shown in Figures 5 to 8 used.

The shuttle proper has a wooden body 11 and pointed steel ends 12. Between the body and the steel ends is the usual fibre plate 13. The front face of the shuttle is provided with a longitudinal groove 1 1 and near the left hand end of the shuttle a channel 16 passes transversely through the shuttle.

At the outer end of this transverse channel is an undercut groove 17 which provides a shoulder 18. The left hand end of the groove 1% is cut back a considerable distance, as shown at 19 in Figure 2, and aligns with the undercut groove 17.

The body is provided with a longitudinal vertical slot 21 which extends into the channel 16 and into an enlarged recess 22 which extends equi-distant from the transverse center of the body. A lever 23 is pivotally mounted at 24: in the slot 21 and its outer end terminates in a downwardly extending pin 26 whose end normally rests in a slight depression 27. This pin is in close vertical proximity to the shoulder 18 and is substantially in alignment with the cut out end 19 of the groove 14 so that when thread is passed into the shuttle by means of the needle of the loom entering the channel 16, it will pass behind the small depression 27 to be caught by the needle when it is lowered.

On the transverse center of the body and of a diameter equal to the width of the re cess 22 is a circular hole 28 into which is placed a spiral spring 29 which exerts an upward pressure on the inner end of the lever 23 so as to normally hold the pin 26 in the depression 2?.

The slot 21 may extend entirely through the body at 31 and that part of the slot beneath the recess 22 may be closed by a plug or plate 32 pinned into the body by the pins 33 or, the plate 32 may be entirely dispensed with and that portion left integral with the body.

It is intended that when pressure is placed on the lever 23 at a point substantially above the spring 29 the said spring shall be depressed, thereby pivoting the lever on the point 24 (which may consist of the bolt, as shown in Figure 2), and thus raising the pin 26 sufficiently high that its lower end will be substantially in alignment with the shoulder 18. This will shed the woven weft loop from the pin and when the needle enters the channel 16, the new weft thread will be laid behind the pin 26.

Figures 5 to 8 inclusive show offset slots 41 and 42 for receiving a left and right hand lever 43 and 44, which said levers are identical with the lever 23 shown in Figures 1 to 4 inclusive.

In this form of shuttle, the recess 46 will of necessity be wider than the recess 22 shown in the former figures because the inner ends of both the levers 43 and 44 will rest above the spiral spring 47 and the pins 48 and 49 on the outer ends of the levers will be simultaneously raised by pressure placed on the adjacent inner ends of said levers.

The right hand outer end. of the shuttle shown in Figures 5 to 8 is identical with the left hand end of the same and with the left hand end of the shuttle shown in Figures 1 to 4.

The form of shuttle shown in Figures 5 to 8 may be universally used with left and right hand looms and may be used in a loom where exceptionally wide cloth is being woven and where the loops must be shed on each side of the warp and a new loop placed alternately on the pins.

The shuttles illustrated in the drawings are susceptible of various modifications and changes without departing from the invention herein set forth and hereafter claimed.
