SHUTTLE-CHECKING MEANS FOR LOOIVIS.

Specification of Letters Patent.

i Application filed July 16, 1904. Serial No. 216,851-

To all whom it 11i/ty concern:

Be it known that I, FRANCIS ARTHUR MILLS, a citizen of the United States, residing at the city of Lawrence, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Shuttle-Checking Means for Looms; and I do hereby declare the following to be' a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The following description, read in connection with the accompanying drawings, will enable any one skilled in shuttle checking and locking mechanism for looms to understand my invention and to practice it in the form in which I prefer to employ it 5 but it will be understood that my invention is not limited to the precise form and details of construction herein illustrated and described, as various modifications and changes may be made without exceeding the scope of my invention and the claims.

Referring to the drawings, Figure l shows in top view'the left shuttle-box of the lay, having the binder located at the back thereof and the shuttle in position having just come in contact with my pneumatic binder. Fig. 2 shows a like view, the shuttle having fully entered the shuttle-box and in contact with the picker and picker-stick to actuate an impact-strap to force the binder against the shuttle to check and lock it. Fig. 3 shows a side view of the same. Fig. 4 is a longitudinal section of the binder, taken on the line 4 4 of Fig. 5, showing my novel pneumatic'and corrugated cushion-shuttle binder. Fig. 5 is a cross-section of the same on the line 5 5 of Fig. 4 showing the air-Chamb ers. Fig. 6 shows the front side of the left end of the boX and means for adjusting the impact-strap to cause the shuttle to be stopped and locked at a predetermined position in the shuttle-box. Fig. 7 shows the protection-finger arranged to operate the binder between the latter and the impact-strap. Fig. 8 shows the same in top view.

The object of my present invention is to arrange an impact-strap so as to yieldingly force a shuttle-binder against the shuttle. To cause this operation, I provide a novel ar- I the shuttle at a predetermined position within the shuttle-box, and the means for effecting this I will now describe.

An impact-strap 4 is arranged at the back of the binder 7 and has one end 5 connected to the lay or shuttle-box, passing across a movable part 6 of a binder 7 around the picker 8 and picker-stick 9 and fastened to adjustable means whichl is connectedto the box or lay, so that the impact of the shuttle upon the picker or picker-stick will cause imipact upon the strap to cause itto force the f binder against the shuttle.

While I have shown the impact-strap as crossing the path of the picker-stick above the lay, obviously that part of the strap which receives the impact of the picker or pickerstick caused by the shuttle may be dropped beneath the lay around the picker-stick and adjustably connected to the lay.

The binder is pivoted to the lay and forms one side of the shuttle-box and is constructed as follows: The contact-face of the binder may be of leather-or a thin sheet of metal 10, fastened upon the binder, and the binder is preferably made in sections and riveted together at its fulcrumed end. Between said contact-facing and the binder is seen a pneumatic cushion 11 to coact with the shuttle. This pneumatic cushioned shuttle-binder, as seen in the drawings, produces its pneumatic function upon the shuttle by one or more airchambers 12, preferably parallel with the binder, so as to produce a pneumatic function upon the shuttle when the latter strikes it and when the said binder is forced against the shuttle by the impact-strap. Coacting with the pneumatic chamber or chambers the face of the pneumatic cushion which joins the binder has corrugations 13 to increase the cushion or pneumatic effect when the shuttle strikes the binder and when' the binder is IOO forced against the shuttle by the effect o1 the impact of the shuttle upon the picker or picker-stick upon said strap.

Referring to the impact-strap, the means for adjusting it to provide for the stretch of the strap and wear of the picker by the impact of the shuttle, so as to stop the shuttle at a predetermined position in the shuttlebox, are seen in Figs. 1, 2, and 6, and consists of a revoluble stud or post 14, secured by a clamp-nut to a bracket 15, which is bolted to the lay, and to said post the strap is fastened and wound around it, so that by loosening said nut on the stud or post the latter may be turned to wind up or let out the strap for its adjustment. I also provide means for laterally adjusting the fulcrumed end of the binder, and for this purpose the binder-fulcrum 16 is an eccentric, and by loosening a nut 17 and turning the eccentric the binder may be moved farther in or out .from the opposite side of the shuttle-box. This adjustment of the shuttle-binder at its fulcrumed end is to give more or less lifting action to the protection mechanism and pneumatic pressure upon the shuttle.

Looking at Fig. l it will be seen that the shuttle has struck the swell of the pneumatic binder with a cushion effect, thus giving easy entrance to the box. The shuttle having entered fully in the box, as seen in Fig. 2, it will be noticed the pneumatic binder has been compressed, which also compresses the corrugated surface of said binder, caused by the impact of the shuttle upon the picker, and thereby cause a pulling action of the impactstrap which has forced said binder against the shuttle with a pneumatic locking function upon the shuttle to lock it at the desired position in the shuttle-box.

The protection device is of the usual form, having the protection-finger 18, its shaft 19, and spring 2O for forcing the finger against the binder, and looking at Figs. 1, 2, and 3 it will be seen that the protection-finger is in engagement with and pressing upon the impact shuttle-locking strap, said strap or band being shown located between the. projectionfinger and the movable end of the binder, so that when the shuttle strikes the pneumatic bind er, forcing its free end out, will cause said strap to be frictionally drawn under springpressure between said binder and the protection-finger, thereby aiding in checking the shuttle while traveling in the box. The protection-finger, however, may be located between the shuttle-locking impact-strap and the binder, as seen in Figs. 7 and 8,which will cause said strap to force the protection-finger against the shuttle-binder and said binder against the shuttle to lock it.

Looking at Fig. 4 it will be understood that the impact-facing of the binder will have .in its contact with the shuttle a yielding function due to the elasticity of the rubber and a yielding function due to its pneumatic function, the combined effect of both these yielding elements being to cause the binder rto conform to the shape of the shuttle while traveling and at the limit of its travel in the shuttlebox.
