SHUTTL-BOX lVlOTlObl FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 626,960, dated June '13, 189e.

the accompanying drawings.

xo Figure 1 ofthe said drawings shows in elevation one of the end frames of a loom having applied thereto an embodiment ot the invention. Fig. 2 is'a rear elevation of cer- ,t-ain of the parts that are shown in Fig. 1.

x5 Fig. 3 is a view in side elevation, on an enlarged scale, of certain parts shown in the preceding figures in which the invention most immediately resides. Fig. 4 is a view in horizontal section through the axis of one of the zo mutilated pinions, showing the details of construction which are employed in connection therewith.

In the drawings, 1 designates the frame work of the loom, and 2 the cam-shaft thereof.

3 designates t-he rotating master-gear of the box-motion, the said master-gear usually in practice being made fast to the cam-shaft 2, as shown herein.

`4 4 designate the mutilated pinions, which 3o are engaged by the said master-gear 3 under the control of pattern mechanism. (Not shown, but on the order of that ordinarily employed in the like connection.) Each mutilated pinion 4 is herein shown formed with a hub 41, Fig. 4, which is fitted and turns within a pipe box or bearing 42, suitably provided on the loom-frame, the said hub having at its inner end a disk 13, carrying a crank-pin 131, which is connected by a connecting-rod 8 with the box-operatin g lever 18.

To the forward end of the box-operating lever 18 is connected -a yielding couplingflink 17 ,of familiar construction, it serving to transmit movement in well-known manner to the 4 5 shuttle-boxes 16. The said shuttle-boxes contain four cells, as shown, and the general arrangement, comprising the box-operating lever, the two connecting-rods 8 8, the two crank-pins 131 131, and the two mutilated 5o pinions' 4 4, operates to transmit movement to the said shuttle-boxes in customary man- Applioation filed April 13, 1899.

ner, so as to present any desired cell of the shuttle-boxes in line with the shuttle-race on the lay.

The master-gear 3 is furnished with the opposite toothed segments 3l 31 for engagement with the teeth of the mutilated pinions and with intervening plain segments or rests 32 32, concentric with the axis of the mastergear.

Each mutilated pinion 4 is provided with two opposit-ely-located toothed-segments 43 43 for engagement with the teeth of the master gear and with intervening untoothed spaces or recesses 44 44, in 4which the teeth of the master-gear may rotate Without actuating the mutilated pinion, the entrance of the plain segments or rests 32 32 of the master-gear into the spaces or recesses 44 44 of the respective mutilated pinions holding the latter locked from accidental movement between the proper times of actuation. Each time a toothed segment 31 of the master-gear becomes engaged with a toothed segment 43 of a mutilated pinion the said pinion is rota ted to the extent of a half-revolution, thereby carrying the connected crank from its top center to its bottom center, or vice versa.

For the purpose of enabling the mastergear to start the respective mutilated pinions when required by turning the latter far enough to bring the teeth of one of the toothed segments on a mutilated pinion into position to be engaged by the -teeth of one of the toothed segments on the master-gear I provide, in connection with each mutilated pinion, a starting-lever 5, which extends diametrically across the corresponding mutilated pinion. This diametrical lever 5 is hung to rotate about the axis of the mutilated pinion in unison with the said pinion. Herein it is mounted on a pivot 51, thatis applied to lugs 45 45 on the outer face of the pinion, and is adapted to swing o n said pivot in a plane extending in the line of the axis of the mutilated pinion. This diametrical lever is intended to be engaged by starting-teeth 33 33, that are provided on the master-gear. The engaging portions of the said lever 5 are on the outer portions 52 l530i.= the arms thereof, measuring from the axis of the mutilated pinion. These engaging portions 52 53 are IOO E t E g out of line or offset with respect to each other, as indicated in Fi". 4, so that when veither of them, as 52, is in the plane of the startingteethon the master-gear the other thereof, as 53, is disposed at one side of such plane. The swinging movements of the diametrical starting-lever in the line of the axis of the mutilated pinion are only sufficient' in extent to place one engaging portion of the lever in the path of rotation of the said starting-teeth and the other engaging portion thereofout of such path, and vice versa. The startingteeth 33 33 are disposed. on the master-gear in position to precede in their engagement with the diametrical lever the engagement of a gear-segment 31 of the master-gear with a toothed segment 43 of the mutilated pinion. Thus I have .herein located the starting-teeth at the ends of the gear-segments 31, and inasmuch as it is intended that the devices shall continue operative in case of the reversal of the running of the loom l have ar-` ranged the said starting-teeth at both ends of each of the said gear-segments of the master-gear.

The construction, arrangement, andrelations of the master-gear and mutilated pinions are such that the parts operate in either direction of rotation of the cam-shaft. Hence when the loom is reversed the shuttle-boxes are shifted in reverse order and the shuttlebox-operating mechanism continues in correct timing with' the harness shedding mechgear.

anism, provided the chaindiead or other indicating device is actuated positively by motion derived from one of the shafts of the loom. The starting-teeth 33 33 on the master-gear in the present embodiment of the invention stand out or project laterally from the master-gear sufficiently to encounter an end of the'lever 5, standing close to the side of the master-gear. (See Figs. 2, 3, and 4.)

14 14 designate levers or fingers forming part of pattern connections, whereby to determine the engagement of the diametrical levers with the starting-teeth on the master- These levers or fingers are connected with and operated from the devices which are employed in connection with the patternchain or other pattern-surface. These levers or fingers are shown constructed and arranged as follows: The finger 14 adjacent to one of themutilated pinions is fast on a short rockshaft 11, supported in brackets 15 15, the said rock-shaft having fast thereon an arm 10. The finger adjacent to the other mutilated pinion is in the form of a lever that is hung loosely upon the rock-shaft 11. The upper arm of this lever and the arm 10 are joined by connections 90 and 100 with the pattern 4devices aforesaid,which last are of any known or preferred character and are not necessary to be shown for an understanding of the invent-ion. The described arrangement of the fingers o r levers 14 14 and their operating connections is adopted for convenience and is not essential to the invention further than by constituting one means of assisting to carry the invention into eeet.

Each pattern lever or finger 14 controls the engagement of one of the diametrical levers with-the starting-teeth of the master-gear. In order to operate the diametrical lever from the corresponding pattern lever or finger a spindle 2O is introduced into a central bore 21, which is formed within the mutilated pinion. A spring 1S), surrounding the inner portion of the said spindle and confined between shoulders on the spindle and on the interior of the pinion, acts with a tendency to force the spindle lengthwise and cause one end thereof to bear against the pattern lever or finger 14. On the said spindle are two fingers, (respectively designated G and 7 in the drawings,) taking against opposite sides of one arm of the diametrical lever. It will be perceived that-when the said pattern lever or finger is actuated to press the spindle 2O inwardly the4 said fingers 6 and 7 will operate to swing the diametrical lever in one direction, while when the pressure of the pattern lever or finger on the spindle is relieved the spring 19 will operate to move the spindle outwardly, so as to swing the diametrical lever in the other direction.

It will be perceived that the diametrical lever is intended to stand normally in such a position that its engaging portion which for the time being is near the master-gear will be 'to one side of the path of rotation of the starting-'teeth on the master-gear, so that it will not become engaged by the said teeth. (See Fig. 4.) When this is the case, the mutilated pinion will remain at rest. lVhen under the dictation ofthe pattern devices the diametrical lever is swung to place the said engage ing portion in the path of the said startingteeth, the n eXt one of the latter to approach the diametri'callever will engage the latter and will operate to turn the mutilated pinion far enough to occasion engagement between a toothed segment of the master gear and a toothed segment of the mutilated pinion. At the end of a half-revolution of the mutilated pinion, the two toothed segments will run out of gear with each other, and thereafter the mutilated pinion will come to rest in consequence of the fact that the end of the diametrical lever which has now been brought around on the side toward the master-gear will stand outside of the path of rotation of the starting-teeth on the master-gear. Consequently the mutilated pinion will remain at rest until the pattern lever or finger is moved, under the control of the pattern devices, to cause the diametrical lever to swing into engaging position.

12 12 designate spring-actuated locking-levers to prevent overrunning or accidental movement of the mutilated pinions and their connections, the ends of the said locking-levers being caused to enter notches in the disks 13 13.

By way of guarding against accidental ill- ICO timed engagement of the ends of the teeth of a segment on the mastergear with the edge of a diametrical lever each of the said levers is rounded or beveled off at its ends on the side thereof which is next the corresponding mutilated pinion, as in Fig. 4, so as to clear the said teeth even if the lever should be slightly misplaced. In case a mistimed action of the pattern devices should operate to swing the lever on its pivot Whilethe mutilated pinion is being'rotated bya segment on the 1naster-gear the inwardly-swung end of such lever would be brought by the rotation of the pinion around into position to strike against the endsof the teeth of such segment, and in consequence of the engagement of such end of the lever by the outer end of the rear starting-tooth 33 of such -segment injury or breakage 'might result. In order to guard against this mishap, the backs of the startingteeth are beveled olf, as at 331, so as to defleet the end of the lever outwardly and pre-A vent the same from becoming caught.
