SHUTTLE-LOCK FOR LOOIVIS.

Specification of Letters Patent.

Patented May 15, 1906.

To all whom, it may concern:

Be it known that I, FRANoIs ARTHUR MILLs, a citizen of the United States of America, residing at the city of Lawrence, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Shuttle-Locks for Looms, of which the following is a specification.

The invention which is the subject of this patent has for its object the gradual checking of the shuttle from the time it strikes the swell of the shuttle-binder to the limit of its throw in the shuttle-box, and at which point the shuttle is stopped and locked in a prede-' termined position in the box. For carrying out this object I have designed a new combination of an eccentric forming the fulcrum for the shuttle-binder, an impact-strap, and lever device connecting the eccentric and strap for actuating the eccentric to actuate the binder. a

The following description, read in connection with the accompanying drawings, will enable any one skilled in the art of shuttle checking, stopping, and locking mechanism for looms to understand my invention and to practice it in the form in which I prefer to employ it; 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.

So far as I know and can find I am the first to employ in a loom an eccentric in combination with a strap to receive the impact of the shuttle to actuate the eccentric for causing the gradual checking and stopping of the shuttle and for looking it in the box at the end of its flight in a predetermined position.

Referring to the drawings, Figure 1 represents in top view the left end of the lay and its shuttle-box of a loom embracing my invention, the shuttle being shown as having entered the box to the position having just come in contact with the shuttle-binder. Fig. 2 is a similar view showing the position of the shuttle as having forced the binder outward to operate the dagger, so that the protector will clear the frog. In this view the dotted lines show the shuttle having reached the limit of its throw in the box and in contact with the picker and the binder and its fulcrum in the position they will be moved caused by the shuttle having moved from the position shown in full lines to the position shown in dotted lines, at which point the shuttle is locked. In these two figures the shuttle guard-plate is seen broken away to expose the movable eccentric fulcrum of the binder. Fig. 3 is a front elevation of the same end of the lay and in which is seen the dagger and the adjustable stop for limiting the upward throw of the dagger. Fig. 4 shows a bottom view of the same end of the lay, the strap connections for the shuttle-locking mechanism, and the dagger device. Fig. 5 shows a rear view of the same end of the lay, illustrating the eccentric and shuttle-looking device which forms the fulcrum for the shuttlebinder and the protection-finger and its fulc'. uni-bearing relation to one end of the shuttle-binder. Fig. 6 is a transverse section on the line an 90 of Figs. 1 and 2, showing the protecting mechanism and its frog in the positions they occupy before the shuttle actuates the shuttle-binder. Fig. 7 is an identical section showing the dagger having been lifted to the stop to clear the frog when the shuttle and its binder are in the positions shown in Fig. 2. Fig. 8 shows in top view, enlarged, the shuttle in contact with the picker 4, having operated the eccentric device for locking the shuttle, as shown in dotted lines in Fig. 2, the shuttle guard-plate being removed. Fig. 9 shows a transverse section of the sarre on the line y y of Fig. 2, showing the eccentric and lever device and its connection with the impact-strap beneath the lay. Fig. 10 shows in perspective the eccentric fulcrum for the binder and the lever and the impact-strap connection for locking the shuttle. Fig. 11 is a view. showing a modification of the impact-strap and spring connections with the eccentric device, the impact-strap being arranged above the lay and having direct connection with the eccentric.

The lay 1, having a shuttle-box 2 thereon at each end of the slot 3 for the picker-stick i, and the picker 4. are of the usual construction. The shuttle-binder 5 is formed with the swell 6 for contact with the shuttle 7 and is fulcrumed on an eccentric device having the impact-strap connection for checking,

stoppin and locking the shuttle. This eccentric ocking device is preferablymounted at the end of the lay on a plate 8, adjustably bolted to it and having a bearing 9 for a shaft 10, which has the eccentric 11 at its upper end and. a lever 12 at its lower end, as in Figs. 41, 5, and 10, and having a strap 13, connecting with the lever 12 for operating the combined eccentric and lever device. The other end of the strap has means 13 for adjustably connecting the impact-strap to the lay. For causing the shuttle-binder, together with its eccentric device, to be pressed inward toward the shuttle or opposite side of the shuttle-box I employ spring-pressure, causing the binder to be spring-pressed at both ends toward the shuttle or opposite side of the shuttle-box against the shuttle, thereby locking it. It is therefore by the protection-finger 14 acting as a fulcrum, as in Fig. 7, to one end of the binder and the eccentric locking device and binder, while the primary fulcrum and the short arm of the binder are being forced out. against the tension of the binder-spring 1.5 by the ingoing shuttle, that the shuttle is being gradually checked until it reaches the limit of its travel in the box and the shuttle is stopped and locked. The secondary bearingfulcrum formed by the protection-finger acts as a pivot-bearing for the long end of the binder as the ingoing shuttle is forcing the short or outer end of the shuttle-binder and lts eccentric locking device outward or away from the opposite wall of the shuttle-box against spring-pressure to gradually check, stop, and lock the shuttle. As a means for limiting the inward movement of the shuttlebinder when the shuttle is out of the shuttlebox I employ a stop 16, preferably an-eccentric, which may be adjusted to allow more or less inward and outward movement to the end of the shuttle-binder which is fulcrumed upon the eccentric locking device, and

this stop serves to limit the inward move-.

ment of the binder under the ressure of the spring when the shuttle is out o the boX. Referring to Fig. 3, it will be seen that the means provided for this adjustment is a long screw 16, passing through the cap-plate 27, through a bore in the eccentric, and down through a hole in the end of the lay and secured on the under side thereof by a clamp-nut 16 as shown in dotted lines, so that loosening the nut leaves the eccentric free to be turned on the screw to allow the eccentric part to be set farther inward or outward and then fastened by the clamp-nut to form the stop against which the binder is spring-pressed when the shuttle is out of the box.

I have shown a strap as the means of receiving and transmitting the force of the impact of the shuttle upon the picker or pickerstick to the binder eccentric fulcrum for looking the shuttle, and this strap and eccentric is the means for adjustably determining the stopping of the shuttle in a desired position in the shuttle-box to receive a bobbin of filling from a magazine to the shuttle, as in the patent to J. H. Northrop, November 27,1894, N 0. 529,940.

The shuttle having been picked across the lay through the shed enters the shuttle-box, coming in contact with the swell of the shuttlebinder, as seen in Fig. 1 and continuing its movement presses the binder and protect-ionfinger out against the pressure of the protector-spring 17 until the dagger 18 reaches an adjustable stop 19, as shown in Figs. 2 and 7 the dagger being thereby lifted to clear the frog. At this stop the outward movement of the protector-finger and end of the binder ceases and then the rotector-finger 14 becomes the bearing-fu crum for the long end or arm of the binder. The shuttle continuing its inward movement to the position shown in Fig. 8 and in dotted lines in Fig. 2 forces the binder and its eccentric locking device out against the pressure of the spring 15 to the position shown in Fig. 8 and in Fig. 2 in dotted. lines from the position shownin Fig. 2 in full lines, and during this time that the shuttle is traveling from the position in Fig. 2 in full lines to that shown in dotted lines the protection-finger becomes a secondary fulcrum for the shuttle-binder. While the shuttle is traveling from the position shown in Fig. 2, full lines, to that shown in Fig. 2 in dotted lines and in Fig. 8 in full lines, the binder and its eccentric locking device moves outward against spring-pressure to gradually check, stop, and lock the shuttle. The shuttle having delivered its impact upon the picker causes the strap to pull upon the eccentric device, and the atter causes th e bind er to be pressed upon the shuttle to lock it. From the time the shuttle strikes the swell of the binder it will be free to be moved outward away from the opposite side of the shuttleboX under spring-pressure to the full extent of the movement of the shuttle into the boX.

For operating the eccentric locking device of the binder by spring-pressure toward the opposite side of the shuttle-box I have shown a spring 15, pressing against the shuttlebi'nder. In Figs. 1, 2, and 8 this spring is shown as adjustably connected to cause it to give more or less pressure upon the shuttlebi'nder. The plate which supports the lever device may also provide a support 21, having a screw 22 for causing the spring 15 to give more or less pressure to the eccentric device of the shuttle-binder inward toward the opposite side of the shuttle-box, a lock-nut for the screw-bolt being employed to maintain the adjustment.

The protection-finger bears upon the binder under spring-pressure, so that when the shuttle enters the boX and comes in contact with the swell of the binder the latter will be caused to be pushed out, thereby pushing out the protector-finger and causing the lifting of the dagger to clear the frog. The dagger will thereby be brought in contact with the adjustable stop, and this stop will prevent the further outward -movement of the protection-finger, which is in contact with the binder, and at this point the protectionfinger becomes a bearing-fulcrum for the binder to cause its eccentric device to be moved outward by the ingoi'ng shuttle under spring resistance.

Referring to Fig. 11, Which is a modification showing the spring 15 as located be neath the lay, it will be seen that the spring operates upon the impact-strap-connected lever-arm 12 of the eccentric device (seen in Fig. and that the pulling action of the spring 15 upon this strap lever-arm is such as to transfer the spring-pressure to the eccentric device upon which the binder is fulcrumed, which causes the binder and its fulcrum to be pressed toward the opposite Wall of the shuttle-box. In this function of the spring its tension is adjusted by a screw-bolt 23 in a depending lug 24 to give more or less pressure upon the binder through its eccentric locking device. In this arrangement of the spring the impact-strap 13 is connected with the eccentric at the top of the lay, the lever 12 for this purpose being added to the shaft 10 in a position on the eccentric just beneath the shuttle-binder, and the connection of the strap with this lever is made by a'pin at the end of the lever by which the strap is caused to pull on the lever to rotate the eccentric under the impact of the shuttle. In either arrangement of the strap it is effective for actuating the eccentric to force the binder against the shuttle. The shuttle-box is provided with the usual cap-plate 25 for the shuttle-binder.

While I have shown and described the shuttle-binder as fulcrumed to yield throughout its entirety, yet obviously my new combination of impact-strap and eccentric may be used with a shuttle-binder not fulcrumed to yield throughout its entirety. 7

It will be noted, looking at Fig. 10 of the drawings, that the eccentric device for looking the shuttle-binder upon the shuttle consists of a single part of three elements, each element having a separate and distinct function in the operation of effecting such lock. Of these elements the vertical shaft 10 is the support and carrier and has a rocking movement in its bearing to impart to the eccentric 11, fixed on its upper end, a rocking movement to the extent of the rocking movement of the shaft and which bysuch movement gives a lateral movement to the shuttlebinder, which is fulcrumed on said eccentric and by which the shuttle-binder is locked, while the lever 12 on the lower end of the shaft in its function transmits the impact of the strap to the shaft to rock it and thence to rock the eccentric, each element having a fixed relation to the other. r 1 In an application filed by me November 6, 1903, under Serial No. 180,121, I have shown, described, and claimed certain parts and combinations of parts, which are shown and described herein, and as to such matters and things I do not claim them herein except in so far as they relate to and are embodied in the new combinations, which are set forth in the claims which form the subject-matter of this patent.
