4 Claims.

My invention relates to" looms and more partic= ularly to control mechanism effective for prevent ing. so-called shuttle smashes" whic'h areusu-i ally occasioned by misalignment of the shuttle boxes relative to the race or each other.

One of the objects of my invention is to provide mechanism effet'ztive', during. operation of the loom, for precluding shuttle operation u-ponfaih' me of the shuttle boxes to obtain preestablished positions.

Another object of my invention is toprovide electrically actuated means or mechanism of the foregoing describedcharacter which may be readily applied to looms already in use without appreciable modification.

An important object of, my invention is to pro vide means or mechanism of the foregoingde scribed character which is simple in construction,

durable in use, efiicient in operation and economical in manufacture.

With the above andother objects in view,- as will. hereinafter appear, the invention consists in the combination and arrangement'of parts here-- inafter setforth andillustrated in the accom-- panying drawings from which the several features of the invention and the advantages attained thereby will be readily understood by those skilled inthe art. I v

Figure 3 is a fragmentarype spective View ofa shuttleboir and guide to which ifiy invention is applied. I

Figured is 93 detail sectional view taken on the line 4 1 of Figure" 1. Figure 5 is a diagram illustrating: the electrical circuit employed. e As diagrammatically illustrated Figure 1 of the'drawing's, there isprov'ided' a loom 5; of ordi nary construction, equipped with the usual iay't having a shuttle race 1' Over which the Shuttle 8 is: operated from and to shuttle boxes" Q'and- I'D disposed at the sinistral and dextral ends, res ectivel'y, ofthelay 6. Each of the shuttle boxes 9 and Ill areprovide'd with a quaternary of compartments'orcells' l1, l2, l3 and I4 arranged one beiow'the other; respectively, it bein understood that a shuttle is projected fidm the eeu of one HOX'iIIt-O' a dell Of the other bOX and that the boxes guide constituting-a pastor or connected to an adjacent side iramemember [8 of the loom while the outer end guide It is secured to a bracket [9 connected at its base to the 10cm frame member.

The loom is also equipped with the usual stop" motion comprising a lower or cam shaft pro-- vided with a cam' 2 I having trackingengagement with one end 22 of acam arm 23 for oscillatingthe latter; The opposite end 24 of the cam is formed with a finger 25' terminating in a tang 26 and, below the finger, is pivoted as" at 21, to a plate 28- having mounted thereon a solenoid .29 provided with-a piston 30 carrying a pin 3l extending through an elongated slot 32 formed inone end of a link 33 pivotly connected to and adjacent the pivoted end of a lever 34 constituting a component of a clutch operating mechanism 35. The lever 3-4" serves to effect operation of the mechanism 35- which includes a clutch operating rod 36 for actuating theclutch of the stop motion and which clutch; as is well-known in the art, functions to connect and disconnect the loom from its power source when shifted to in and out positions,- respectively, by the rod 36. When the clutch is in its in position and the loom operating, the link 3-3 is in the position shown in Figure 2 of the drawings. Howevenby manualoperation of one of the leversorhandles 31 of the mechanism 35,-the1ink 33- may be shifted to dispose its free end in close proximity to the finger 25 for engagement with: the latter occasioned by oscillation ofthe arm 23 whereupon the'link 3'3 functions-to pivot the lever 34 with the result that the clutch; rod 36 is actuated and the clutch shitted to its out position, thus-,disconnecting';

the power source from the loom and: stopping the latter. However,- the solenoid 2-9 may be energized to dispose the free end of the link 33 into the path of the tang 26; thus. whenthe' tang 26 engagesthe free end ot thelink 33-, the clutchis shifted to foot position; throughthe medium of the lever 34 and rod 36 as describedito' effect stopping of the 1oom=,. it being understood that the solenoid 2 9 is connectedin: circuit with the feeler Y motion drop wires andyor devicesof the'loom inthe usual manner and-ior well known purposes;

3 In practicing my invention, I secure a relatively narrow and elongated strip or plate 55 of insulating material to each of the outer guides IS in any suitable manner and which plate has embedded in its front face thereof, a vertical row of spaced contact discs 5!, the latter, in the present instance, numbering eight with the discs being equally spaced on each side of the horizontal center of a cell of the adjacent shuttle box when the latter is properly positioned for shuttle operation relative to the race. The front face of the guide [6, on which the plate is secured, is provided with a longitudinally extending slot 52 in which is disposed a pair of lead wires 53 and 54 extending along the rear face of the plate.

As illustrated in Figure 5, the wire 53 is connected, through the rear of the plate, to each alternate disc of the row While the wire 54 is similarly connected to the remaining discs. The wires 53 lead from the discs 5| and are connected to a common ground G while the wires 54, which also lead from the discs 5!, are connected to a wire 55 which, as is w ell-known in the art, leads from a terminal of the aforementioned feeler motion, drop wires and/or other devices to one terminal or source 55 of electrical energy. The other terminal of the source 55 is connected to one terminal of the solenoid 29 by a wire 57 while the other terminal of the solenoid is connected to the ground G by a connection 58, the opposite terminals of the feeler motion, drop wires and/or devices being also grounded.

Each of the shuttle boxes 9 and H3, adjacent the top cell ll thereof, has secured to its front face one end of a somewhat Z-shaped arm 55, the other end of the arm extending over the plate 50 and having secured thereto a bar iii of insulating material. The bar has fixed thereto a terminal member 62 forming part of a U-shaped bracket 63 in which is rotatably mounted a roller 64 having electrical engagement with the member 62 through the bracket 53. The roller 54 is arranged for tracking engagement over a vertical path on the plate 50 and in which path are disposed the contact discs 5| with the outer radial faces of the discs being disposed in flush relation with the front face of the plate 50. The terminal members 52 are connected together by a bridging wire 65 forming a part of the circuit in which the solenoid 29 is connected for operation with respect to precluding shuttle smashes as hereinafter made apparent.

During normal operation of the loom, the shuttle boxes 9 and H] are shifted vertically and in unison to maintain the cells 1! to 14 inclusive of one box in aligned relation with the cells it to 14 inclusive of the other box, respectively, and to effect alignment of a pair of the cells, for instance, cells I I, with the race 1 whereby the shuttle 8 may be projected out of one cell I! by the picker stick, across the race, and into the other cell ll. When the shuttleboxes are shifted in unison, the rollers 64 engage a disc 5! on each plate and which pair of discs thus engaged, are either connected to the wires 53 or to the wires 54 with the result that the circuit is not closed and the solenoid 29 remains deenergized. However, if by faulty operation of the box change motion or otherwise, the shuttle boxes are relatively shifted, the rollers 64 will engage a pair of the discs which are connected to the wires 53 and 54, respectively, as illustrated in dotted lines in Figure 5, thereby closing the circuit and effecting energization of the solenoid 29. solenoid 29 is thus energized, the link 33 is raised When the and including a solenoid by the piston 30 and pin 3| and with its free end disposed in the path of the tang 26, whereby the latter, due to the oscillation of the arm 23, engages and operates the link to shift the lever 34 and actuate the clutch rod 35 through the mechanism 35. When the rod 36 is thus actuated, the clutch isv operated to its"out position to disconnect the power source from the loom whereby the latteris stopped.

When the loom has thus been stopped, it necessarily follows that necessary adjustments or repairs will have to be made to effect operation of the shuttle boxes in unison before the loom may be again operated in conjunction with my invention.

It is to be noted and understood that the stopping of the loom occurs before any operation of the picker sticks is effected thus rendering the sticks inoperative for projecting shuttles from the cells. As herein disclosed, it will be apparent that the present invention provides effective means for preventing shuttle smashes occasioned by misalignment of the cells of the shuttle boxes, and that the invention may be incorporated in looms already in use without appreciable modification.

Without further elaboration, the foregoing will so fully explain the invention that others may, by applying current knowledge, readily adapt the same for use under various conditions of service. Moreover, it is not indispensable that all the features of the invention be used conjointly since they may be employed advantageously in various combinations and subcombinations.

It is obvious that the invention is not confined to the hereindescribed use therefore as it may be utilized for any purpose to which it is adaptable. It is therefore to be understood that the invention is not limited to the specific construction as illustrated and described, as the same is only illustrative of the principles involved which are capable of extended application in various forms, and the invention comprehends all construction within the scope of the appended claims.
