(Cl. 139-186) This invention relates to a shuttle box con stick check thereby making it possible to eliminate struction for looms and more especially to a shuttle box equipped with means for frictionally engaging the side of the shuttle as it is thrown 5 into the box and stopping it in the proper posi tion, and therefore, dispensing with the usual check strap. This invention makes it possible for the shuttle to be properly located at the time it is thrown into the box in proper contact with 10 the picker so that the impact delivered thereto by the picker will be uniform. In the conventional shuttle box the shuttle enters the loom and rebounds a certain amount. Since this rebound is not uniform, the impact or 15 blow delivered to the end of the shuttle by the picker will Vary from time to time, thereby caus ing a mis-pick, pick-outs and other imperfec tions. By equipping one side of the shuttle box with a movable lining which is normally adapted to be engaged by the shuttle and by having an eccentric pivotally mounted in one side of the shuttle box for causing this movable lining to engage the shuttle, it is possible to cause the shuttle to stop- almost in the same position in the 25 shuttle box at each pick of the loom. . It is, therefore, an object of this invention to provide a shuttle box for each end of the lay of a loom having one side thereof equipped with a movable lining for engaging the sides of the 30 shuttle as it enters the loom and means controlled by the movement of the shuttle for producing frictionv between the side of the shuttle and the movable'lining. When the shuttle is thrown from the shuttle box means are also provided for re 35 turning the movable lining to its original position so that it will again be engaged by the shuttle when it is thrown again into the shuttle box. By using this movable lining together with the eccentric as shown in the drawings, I have found 40 that it has been possible to operate the loom at a much higher'rate of speed than was possible by using the old type of shuttle box. This in crease in the number of picks is due primarily to the fact that the shuttle is'not allowed to re 45 bound a suf?cient amount in the box to mate rially affect the operation of the picker, and there fore, there need not be the appreciable pause now present in looms to allow the shuttle to assume a position of rest before the picker is operated. 50 .' It is a further object of this invention to pro vide a' combined shuttle engaging means, for maintaining the shuttle in the proper position in the shuttle box, and a picker stick check. Not only does this movable lining serve as a shuttle 55 engaging, means, but it also serves as a picker the conventional check strap for this purpose. It is a further object of this invention to pro vide a shuttle box construction which has mount ed in the pivotal binder on one side thereof, an eccentric resilient cam for engaging the side of the shuttle to maintain the same in its proper position when it is thrown into- the shuttle box. In this type of the invention no strap is used but the action of the resilient leather covered eccen 10 tric is depended upon to produce the necessary friction and prevent vibration of the shuttle to insure the proper stability. Another object of this invention is to provide a shuttle box for each end of the lay of a loom 15 having one side thereof equipped with a mov able lining for engaging the sides of the shuttle as it enters the loom and means controlled by the movement of the shuttle for producing the friction between the sides of the shuttle and movable lining, said means being adjustably se cured preferably to the lay of the loom. By adjustably securing the controlling means to the lay of the loom a very stable construction is pro vided, and the movement of the pivoted binder as in the case of the other showing, does not affect the frictional or the shuttle engaging means. A still further object of the invention is to provide a shuttle box construction comprising a resilient eccentric cam mounted in an adjustable bracket, said bracket being mounted on the lay of the loom. This form is similar to another form shown in the drawings with the exception of the means for mounting the eccentric. In this case the eccentric is mounted on an adjustable bracket instead of being mounted in the pivoted binder. Some of the objects of the invention having been stated, other objects will appear as the de scription proceeds when taken in connection with the accompanying drawings, in which:— Figure 1'is a plan view of one end of the lay of a loom showing the invention applied thereto; Figure 2 is a rear elevation taken along line 2—2 in Figure 1; Figure 3 is a transverse sectional view taken along line 3-3 in Figure 1; Figure 4 is an elevation taken along line 4-4 in Figure 1; Figure 5 is a transverse sectional view taken along line 5—-5 in Figure 1; Figure 6 is a plan view of the right-hand por tion of Figure 1 showing the shuttle removed therefrom with the parts in a different position; 45 2 2,105,578 lining 3% extends to'the right, (Figs. 1 and 6), Figure '7 is an isometric view of the pivoted back binder of the box construction; across slot liib and behind the picker I5 and has one end thereof secured as at 44. to bracket 45, said bracket 45 being secured to the lay cap l?a. ' Figure 8 is an isometric View looking at the back side of Figure 7; Figure 9 is a plan view of another modi?ed form showing the resilient eccentric cam ad justably secured to the lay of the loom; Figure 10 is a cross-sectional View taken along line l5—l5 in Figure’ 9; Figure 11 is a plan view of still another modi?ed 10 form; 15 and ' ' When the shuttle l3, under the impact deliv ered by the picker stick at the other end of the loom, is driven to the position shown in Figure 1 the side adjacent the movable lining 39 is. caused to engage the lining. The friction produced be tween the lining and the side of the shuttle will 10 cause the eccentric 3‘! to rotate about its pivot point 36. The greater the blow given to the shut - Figure 12 is an isometric view of the eccentric cam and the adjustable bracket shown in Fig , tle I3 the more counter-clockwise rotation will be caused in the eccentric 3'! thereby causing the ure 11. Referring more particularly to the drawings, friction of the lining 39 on the side of the shuttle the numeral ill denotes the lay of a loom which 83 to be increased. Also when the shuttle en has mounted on the upper side thereof a lay cap gages the picker and moves the picker against the Hla. The lay cap supports the conventional box strap 39, increased force will be applied to eccen front l I which, in turn, has secured to the inner tric 31 and the force of the moving shuttle will side thereof a' strap of leather I2 for engaging positively move the eccentric and further grip the the side of shuttle 23 when it isthrown into the shuttle. It is evident that after the picker l5 shuttle box.

The structure thus far described is conventional lining 39 and be immediately clamped in position but it is thought necessary to makea showing of thereby eliminating the vibration or oscillation of the shuttle which has heretofore taken place this in order to e?'ectively disclose the present in vention. Pivotally secured as at H is a back in the shuttle boxes. The strap 39 also serves as a picker stick check since the backward move piece or binder l8 which has securedv to approxi mately one half of the free end thereof a leather ment of the picker stick will be resisted by the lining 26. This lining 2b cooperateswith the lin spring 4| and the friction of the strap on the ing 52 to provide a lining for the shuttle box for Figures 9 and 10 show another modi?ed form receiving the shuttle l3. vSecured to the back side of member i8 is a wearing member 21 such which is similar in many respects to the form as leather, which is normally engaged by resilient shown in Figures 1 to 3 inclusive, and like refer arm 22 said arm being pivotally secured as at 23 ence characters will apply to like parts. The to a bracket 2a. In order to normally hold the principaldi?erence between these two forms is, free end of arm 22 into engagement with member that in the present form the resilient eccentric 2! a torsion spring 25 is provided. This arm and cam 3'! is pivoted as at 80 to the upper portion of its‘ associated parts are conventional, and serve to bracket 8!. The lower side of bracket 81 is ser rated and is adapted to rest upon a serrated face cause the back side wall of theshuttle box to en gage the shuttle to produce a certain amount of of bracket 82 and is adjustably secured thereto friction and resiliency. _ by any suitable means such as stud bolts 83 which In order to limit the pivotal movement of binder penetrate slots 84 in the outstanding leg of said it about pivot point I‘! a bracket 30 is secured bracket 8| , It is seen that by mounting the in the lay l0, said bracket having threadably se bracket in this manner, instead of placing it in the cured in the upper end thei'eofva bolt 3! with pivoted binder l8, that adjustment can be made as a resilient tip 32 on the end thereof. The tip to the amount of friction desired and as to the 32 is held in the proper position by means of lock proximity of resilient eccentric cam 31 and lin nut 33 and this tip serves to limit the outward ing 39 to. the shuttle to thereby control the fric shuttle. 40 45 50 ' ' the torsion spring 25 has become weak the pivot a1 movement of the binder 16 or a similar mem her with which the arm 22 has’worked a greater amount of outward rotation has been allowed the wear on the binder will not be nearly so great as it is when the binder contains the movable than has been necessary thereby causing the check lining' 60 shuttle is to vibrate in the shuttle box. Further more, screw 3! insures proper friction being ap I, _' 7.

The cam 50 is pivotally mounted as at 86 in the upper side of bracket 8| a. This bracket is similar in all respects to 65 bracket 81 with the addition of the projection 81 which extends laterally therefrom to which spring 56 is normally secured. This spring con tacts the cam 50 in the same manner as shown and described in Figure 9. Likewise, in this form, by having the cam on a stationary bracket adjustably secured to the lay a more stable con~' struction is provided and less wear is produced which lining cooperates with lining ‘29 ion the ‘ onthe pivoted binder. 75 same side of the shuttle box. 40 Figure 11 is another modi?ed form in which the 60 resilientrcam '50 and leaf spring 56 are mounted plied to the shuttle to properly and quickly box ably made of leather, ?xed thereon. A movable lining “is is secured intermediate its ends to the eccentric cam 3'? asgatYliLand secured to one end thereof is a tension spring’éll, the othervend of, 70 said tension spring being secured to the binder Hi. This movable leather lining 39 extends through an opening or recess 42 cut in the side of binder IE to form a lining ior the shuttle box, 10 in tion. By having the bracket fastened to the back side of the lay it makes a very strong and stable 55 check and adjustment can be easily made. Also pivotal movement of binder l3., Heretofore, when the same. 20 ' - The eccentric 52, as appearing in Fig. 11, has 75 3 2,105,578 a leather cover 52, and the eccentric has secured as at 53 a tension spring 54 which has its other end secured as at 55 to the binder Hi. In order to prevent the eccentric 50 from vibrating or oscillating after the shuttle has been thrown into the shuttle box, a leaf spring 56 is provided which has one end thereof secured to brackets 81, with its free end frictionally engaging the side of the eccentric. Leaf spring 56 and tension spring 54 normally hold eccentric 50 in the dotted line position when the shuttle is not in the shuttle box. When the shuttle enters the shuttle box the side of the shuttle engages portion 52 and ro tates the eccentric to the bold line position. By 15 positioning leaf spring 56 in the manner shown, it is evident that the further the shuttle enters the box the greater resistance spring 56 will offer, thereby causing the resistance to the travel of the shuttle to be in direct proportion to the speed 20 thereof. In the drawings and speci?cation there has been set forth a preferred embodiment of the invention, and although speci?c terms are em ployed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being set forth in the appended claims. I claim: 2.
