A vertically disposed guide =bracketindicated generally by the umerai nan-is mounted uponthe outer end of the-horizontal-oriower portionof the s ipport panel 24'; and'as shown in Figure 7 eqn prises a pair ofparalle1---horizonta1 'leg memhers 512 and-4Q having a' pairef parallel-vertically disposed guide rods' iiiand 48 integrally secured t reto. The'ie'gsfiz and 214 are provided with fastening 156 -scre'w threaded1y engaged thereon wlireiiy me? guide bracket 40 is secured to the panel. The horizontal leg 34 of the slide 28 is disposed in the vertical guiding slot between the member 48 and the adjacent surface of the panel 24, while the horizontal leg 38 of the slide 36 is disposed between the guide rods 46 and 48 and are thus vertically slidable between the upper and lower legs 42 and 44, and are capable of independent tilting motions therein as shown by examining Figures 3, 9 and 10.

Upon the vertical portion of the panel 24 there is provided a pair of guide hooks 52 and 54 which are disposed on opposite sides of the slide 28 and are spaced vertically therealong as shown clearly in Figure 3. The arrangement of hooks is such that pivoting movement of the L-shaped slide 28 in a counterclockwise direction as shown in Figure 3 is prevented, but a clockwise pivoting movement is possible as will be seen by comparing Figure 9 with Figure 10. To the upper end of the slide 28, is secured a cable 56 by which the slide is vertically reciprocated upon the panel for a purpose which will be later set forth.

Secured to the horizontal leg of the panel 24 on the opposite end thereof from the guide bracket 46, see Figures 3, 5, 8-10, is a guide strip 58 upon which is mounted a guide bracket 66. The space or slot between the bracket 60 and the guide strip 58 is disposed in parallel arrangement to the space between the members 46 and 48 of the guide bracket 40 and with the latter space constitutes a guide slot in which is vertically reciprocable the horizontal leg 38 of the slide 36. It will be observed that the slide 36 and the horizontal leg 38 are spaced outwardly of the panel 24 from the slide 28 with its horizontal le 34, the slides 28, 36 thus lying and moving in parallel vertical planes, so that no interference between these slides will be possible during their sliding and tilting movements.

The slide 30, at the junction of the vertical and horizontal legs 36 and 38, is provided with an apertured lug 62 and the end of a cable 64 is secured thereto by which the slide is vertically reciprocated upon the panel for a purpose .to be subsequently made apparent.

As seen from Figure 6, the lower corner of the support panel 24 is provided with a notch or cutaway portion as at 66 and a stub axle 68 is fixedly secured to the panel upon what may be termed its rear side, that is, upon the side opposite the brackets 60 and 46, this stub axle being secured by welding as at I and extending into the notch 66. A guide pulley 72 is journalled upon the stub axle and retained thereon by a threaded nut I4, and the above mentioned cable 64 extending downwardly from the lug 62 is entrained over this guide pulley and from thence extends upwardly behind the back side of the panel as will be seen from Figures 2, 6-8.

Referring now to Figure 2, it will be seen that the cables 56 and 64 are respectively entrained over further guide pulleys I6 and I8 which are respectively carried by support brackets 80 and 82 detachably secured on the frame I0 of the loom and are then positioned horizontally across the top frame of the loom and after passing over further guide pulleys 84 and 86, respectively, extend upwardly and are attached to the customary Jacquard cards and control the head mo-' tion of the loom. Thus, the cables 56 and 64 will be moved in synchronization with the head motion to cause vertical reciprocation of the slides 28 and 30 in synchronization therewith.

It Will be noted that the horizontal leg 38 of the slide 30 is provided with a collar 88 fixedly secured thereto which is adapted to bear against and abut the left hand side of the guide 46, as viewed in Figure 3. This collar prevents sliding movement of the horizontal leg 38 towards the right, although movement toward the left is possible.

Between the guide brackets 60 and 46, the horizontal leg 38 has secured thereto in a desired manner a tension spring 90 Whose D1 end is fastened in any desired manner to the support panel 24. It will be noted, as viewed in Figure 3, that the upper end of the spring 90 is disposed above and slightly towardthe right of the fastening of the spring upon the horizontal arm, whereby the tension of the spring will both pull the slide upwardly, and also urge the leg 38 of the slide towards the right, with the collar 88 in slidin abutting engagement with the guide bracket 40.

The vertical arm 36 of the slide 30 is slidably received beneath two L- shaped slide hooks 92 and 94 which are mounted upon the support panel with horizontal supporting legs and lateral arms extending over the adjacent vertical edge of the panel. The vertical leg 36 of the slide 30 lies outwardly of, Or against the left side of the legs of the hooks 92, 94, as shown in Figures 3, 9 and 10, this arrangement preventing tilting of the slide 36 in a clockwise direction as viewed in Figure 3, but permitting counterclockwise tiltin as shown in dotted lines in Figure 3 and in Figure 9.

Secured to the vertical leg of the support panel 24 and preferably slightly above the guide hook 92, is a laterally extending guide strip member 96 which is welded or otherwise secured to the front surface of the panel 24 and extends laterally beyond the edge thereof. The top surface of the strip lies in the same vertical plane as the top surface of the guide member 58 and of the guide surface of the guide rod 48, and with those members serve to slidingly support the undersurface of the slide 30, engaging its vertical and horizontal legs 36 and 38 respectively. The member 96 extends sufiiciently laterally and outwardly from the support panel 24 to guide and support the guide 30 when the latter is in a tilted position as shown in dotted lines in Figure 3 and Figure 9.

Welded or otherwise fixedly secured to the front surface of the support panel 24 and between the slide hooks 92 and 94 are a pair of parallel supporting lugs each indicated by the numeral 98. A lever I06 is pivoted to the lugs 98 therebetween, and has pivotally attached to its opposite ends an actuating link I02 and a cable I04. The link I02, see Figure 4, is pivotally attached to one end of a lever I06 which extends through a slot I08 in the support panel 24 and is pivoted intermediate its extremities to this panel as by pivot pin III]. By means of the hook fastener II2 secured to the same end of the lever I66 as the link I02 but at the opposite side thereof, a cable I I5, see also Figures 1, 2 and 9, connects the levers I06 and I00 with a loom stop motion Ill which may be mounted upon the front of the loom frame I0 and may be of the type and construction set'forth' in my prior co-pendin applications Serial Nos. 208,345 and 214,377, filed January 29, 1951, and March 7, 1951. The cable I64 may extend to any convenient location, as to the rear of the loom, and comprise manual operating means for the levers I00 and I06.

As'So far descri=bed;r"it will be apparent thatthe tilting movements of' either of the slides 28"an'd 30 will thus be efiecti've' to tilt 'the lever l 86 in' a clockwise direction'as viewed in" Figure 4' and thereb /actuatetnestopmotion H1.

On. the rear side of the panel 24 as snewnmcre clearly in Figures 4, 6, '7 and 8, the upper end of the lever we is attached to a -link l 13,, which -in turn is'connected with an electric switch H4 of any suitabiedesign- "and iermingparr'or the electric power circuit of the loom: It will thus-be apparent that upon actuatiorr-offithe lever- 106, the-switch will be actuated in turn, and in an'y desired manner will stop the operation of the loom. As hereinbefore set forth, the cable [04 comprises a manual means actuatable remotely, for stopping the loom by tripping the switch H4 or the stop motion I [7.

Referring now again to Figure 1, it will be seen that the stop motion attachment of this invention is mounted upon the frame of the loom in such a manner that the horizontal legs 38 and 34 of the slides 28 and 38, are disposed respectively between the top and bottom beams l4 and I6 of the batten i2, and between the bottom beam 56 of the batten and the reed lay [8. In this position, the vertical motion of the batten and the arcuate horizontal and vertical motion of the reed lay will cause the members l4, l6 and I8 to move both vertically with respect to the horizontal legs of the slides. By the cables 56 and 6d, the slides are likewise caused to move vertically in timed relation to the vertical component of the batten motion so that no pressure is applied to the horizontal legs by the motion of the batten, when the head motion and batten are properly synchronized. However, if for any reason the head motion of the loom fails to function as called for by the pattern cards, there will be corresponding failure of the cables 56 and 8G to vertically reciprocate the slides 28 and 30. Consequently, the vertical component of motion of the batten will then tilt whichever of the slides is not vertically reciprocated in timed relation thereto, thereby causing through the tilting of that slide actuation of the switch H4 and of the cable I I5 and stop motion II! to thereby stop the operation of the loom.

The operation of the loom with this head and batten stop motion attachment applied" thereto is as follows: The cable 56 is pulled up by the hooks of the Jacquard head and as the blades of the Jacquard head raise and lower, the hooks of the Jacquard head rise and fall, lifting the slide 23 and permittin the same to drop in synchronization or timed relation to the rise and. fall of 6. th e' beittirby tlre side metre J the head anebetted: and feed la'y are 0 the batten bar it does not apply pressure to -the" hofi zonta-l -leg 34 5f theslide 'i'a' arid therefoi"e the "latter" reciprocates*verncany Without writings If the head" and betterget outer 'tli'fif'sdthxt the :baaea does not raise-atthdtinl'e' required" by the-head motionfwhiclrattherequird'timeraises tlf slide the stationary batten bztl H3 Will-fir?- plya downwardly and; a clockwise tiltingpres'sure to= t1i u per=surfateor the'vei'tically ascending leg '34, "which will tilt the slide 28" to thepo'sitioh shownin F u IO/thus actuatingthe lever 106, which through" link l 3 will actuate the switch I M ancl 'througlr cable I i5 "will actll'aite the stopmotio'n" l Fl -to stop theloom:

It is evident that this mechanism can be applied on various convenient portions of the loom frame since the flexible cables 56 and 64 will permit easy attachment of the mechanism to the head motion of the loom.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to 'be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.
