BROKEN-PICK EXTRACTOIR, FOR LOOMS.

Specification of Letters Patent.

Continuation of application Serial No. 108,197, filed July 8, 1918. This application filed *Jnly 16, 1918.

Serial No. 245,202. 1

To all whom it may com-em:

Be it known that 1, CHARLES CROMPTQN, a citizen of the'United States, and a resident of \Vorccster, in the county of Worcester and State of Massachusetts, have invented an Improvement in Broken-Pick Extractors for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like arts. P This application is a continuation of my co-pending application Serial No. 108,197, filed July 8, 1916.

This invention relates to looms for weaving fabrics and the like and particularly to means for extracting a broken partial or incomplete pick from the shed of the warp in looms of the above character.

The object of my present invention is the provision of means arranged to enter the open shed of the warp, and after the filling pick has been passed through said shed, should said pick become broken or be incomplete through exhaustion to remove said1 broken or incomplete pick from said she With this and other objects in view my invention consists in a novel combination and arrangement of parts hereinafter described and more specifically pointed out in the appended claims.

In the accompanying drawings I have shown my invention combined with a ortion of a 100m sufficient to enable t ose skilled in the art' to understand the construction and operation thereof.

Referring to the drawings:

Figure 1 is a transverse section of a portion of a loom embodyingm improvements;

Fig. 2 is a plan view of Fig. 1, in this view the loom frame and some of the parts are omitted;

Fig. 3 is a detail front view of my improved broken pick extractor;

Fi 4 is, on an enlarged scale, a sectional detai of the upper portion of the extracting members;

Fig. 5 is a view correspondin to Fig. 4, but shows the plunger in a di erent position;

Fig. 6 is a view similar to the upper art of Fig. 3 but representing the tubes as aving their openings or slots directed downward; and

- contained therein.

17 are the warp threads and 18 is the woven fabric.

The above described parts are or may be of the usual and well known type.

I will now describe my improved pick extracting device as combined with the above mentioned parts.

In this instance I have provided a vertical member 19, the upper end 19 of which has slidably mounted therein a plunger 20, said plunger 20 having an opening 21 which extends upwardly from the lower end of said plunger 20 and connects with an opening 22 which extends from said opening 21 to the periphery of said plunger 20.

The upper portion 19 of the member 19 has a tapering projection 19' to which is secured, in this instance, a tube 23, the longitudinal wall of which has a horizontal opening 24 therein. Said tube 23 has a driving fit upon its projection'19 and can be turned or adjusted b a wrench or otherwise so as to direct t e slot or opening 24 in an direction throughout 360. If desired both tubes 23 may be positioned with their slots 24 directed downward, thereby very effectively to insure the sucking in of both parts of a broken pick, one at each end of the lay. If at each end of the lay the slots 24 be directed toward the fell of the cloth, I insure the sucking in of the Patented Oct. 28, 1919.

adjustment, as

to a stand 27 secured to the floor, said stand 27 having a horizontally extending arm 28 to which is pivotally connecterh'one end of a connecting rod 29, the opposite end of said connecting rod 29 being pivotally connected to a collar 30 secured to the lower portion of the plunger 20.

Secured to the lower end of the plunger 20 is one end of a flexible tube 31, the opposite end of said tube 31 being secured to a vacuum tank (not shown) which may be of any suitable and well known construction.

I have only describedone of the devices as the opposite device is of like construction, the two devices being retained in their inner operative positions by means of a spring 32 extending between the two devices.

I will now briefly describe the operation of the above mentioned parts.

If the filling 16 should become broken while being passed through the open shed of the warp 17, see Fig. 2, the tube 23 being inserted in its operative position, and the plunger 20 being in its upper position with the opening 22 cooperating wit the openin 25, thus causing a vacuum to be produced in the tube 23, the broken end of the filling will be carried through the t be 23 and thus through the o enings 25 and 22 into the opening 21 in t e plunger 20 before the forward beat of the lay.

On the forward beat of the lay the cams 33 secured to the lay beam 14, will engage the members 19, causing said members to be moved outwardly as shown by broken lines Fig. 3.

As the members 19 are moved outwardly the plunger 20, through the connectors 29.

will be caused to move downwardl", thus closing the openings 22 and 25, see ig. 4.

.As the plunger 20 is carried downwardly the filling end will be severed by the edges of the openings 22 and 25.

I have shown the filling fork mechanism mounted on the breast beam, but if desired the filling fork mechanism may be mounted on and operated by the lay in any of the usual and well known ways.

In Fig. 6', I have represented the tubes '23 as having their slots 24 turned downwardly. The said slots may in any event be of any desired width.

In Fig. 7, I have represented one of the tubes 24 as secured with a driving fit upon the nipple or projection 19 and have represente a set screw 23 constituting additional means for securing the tube upon said nipple or projection and received in a transverse slot 23" in said tube. The tubes 23 are held, because of the driving fit, securely upon the projections 19 against all liability of falling off under the impact of the lay. and yet with capacity for rotative by the application of a hand 24, it may not be necessary or worth while to suck in the end of the broken pick which is at that side of the loom occupied by the shuttle just after laying the broken pick; that is, at the left hand side of the loom, viewin Fig. 2.

It will readily be seen and appreciated by those skilled in the art that I have provided a simple and efficient device for removing a broken pick from the open shed otthe warp without the necessity loom. The uprights or members 19 are in practice preferably made of tempered steel, and this fact, together with the joints or pivotal points 26 gives ample springing facilities when the lay hits the tubes 23 after the latter are withdrawn from the ends of the shed by the cams 33. Thus in practice the lay serves properly to beat up the filling at the fell of the cloth and the tubes 23 with their supports yield suliiciently for this purpose.

Having .thus described my invention, it will be evident that many changes and modifications may be made therein by those skilled in the art without departing from the spirit and scope thereof, therefore I do not wish to be limited to the specific details herein disclosed, but what I claim is:
