The present invention relates to looms, and more particularly to the arrangement thereonof the controls for starting and stopping the same.

6 It is the usual practice to arrange looms, in a mill, in parallel rows, the looms in each row being positioned side by side as closely as may be without interference and all of the looms in a row facing in the same direction;

10 The looms in adjacent rows face in opposite directions, andspace is left between the rows to constitute an alley-way. The alley toward which the front, or cloth take-up, ends of the looms face is known as the front alley, and the next alley over, which is flanked by the back,-or warp let-off, ends of thelooms, is known as the back alley. Cross alleys are provided at varying intervals.

In accordance with accepted practice,- the weavers spend most of their time in theback alleys, from which position it is more convenient. to tie in brokenwarp ends and detect and; repair other faults in the warp sheet which might cause imperfect operation of the looms. The duties of the weavers include the restarting of the looms after the repairing of defects in the-warp or filling or after the 100m has-stopped from any other cause not requiring the attention of a loom fixer.

Obviously, if a loom fixer is-stooped over fixingany of the various devices on the front or sides of the loom the restarting of the loommight injure him quite severely. Were the shipper handleto be placed atthejback of the loom there would'be considerable danger of such-injuries occurring, because, when a-weaver discovers a loom stopped with no apparent defect in the'warp or filling, the first actperformed is to pull the shipper 40 handle to on position to determine whether the loom will run ornot. Accordingly, for the foregoing reasons, andfor the convenience ofthe loom fixer in testing the loom after he has" repaired it, it 5 has-been considered necessary to place the shipper handle on'the frontof the loom. As a result, it has been necessary for the weaver in restarting the loom, either to reach entirelyacross the 100m if that were physically practicable, or'to walk a considerable dis- 1932; v sear No. 616,538;

tance in finding a cross alley by which to gain access to-the front alley, where the shipper handle ismore accessible.

It 'is, acc'ordingly the principal object of my invention to provide a loom having anarr'a'ngement' of controls thereon which-shall be more convenientfor the Weaver but which shall provide ampleiprote'ctio'n for the loom fixer against injury sustained from unauthori'z'e'd or accidental starting ofthe loom.

More specifically stated, it is the object of my invention to provide,.in a loom having'a driving shaft, and a releasable clutch for applying power'thereto, a shipper handle at the backof' the loom for the weaver, a shipper handleatthe front of the loom, and means controllable from the front of. the 100111 for rendering the shipper handle at the back of the loom inoperative. 1 u 4 Further objects of my invention will, in part, be herein after more specifically enumer ated and will, in part, become obvious as the description proceeds.v g

Referring to the accompanying drawings, which illustrate the preferred. embodiment of my invention: i

V Fig. l is 'a. more or lessdiagrammatioplan view showing the relative positioningfof a number of looms as'they are usually arranged inthe mills; i v i Fig. 2 is anelevation taken from the right hand'side'of one of the looms shoWnin Fig. 1, certain parts being omitted for sake of. clear ness Fig. 3 is a perspective view of a portion of one of the shipper handlesand contiguous parts ;.and

Figs. 4 and 5 are detail Views of one ofthe parts appearing in F ig. 3. i

As is-more clearly shown in Fig. 1, looms A, B, and C are placed side by sidein arowl; with their lays L almost touchingandwith their fronts, as evidenceby the breastbeam 1, all facing in the same direction. The looms D, E and F are similarly arrangedexceptw that they face in theopposite direction to the looms A,- B and C. The two rows of looms are, as shown, spaced apart' a-suflicient distance to form an alley way. Since this alley is the one that is flanked by thewarp let-offs W, which are always at the back of looms, it is known as the back alley. The front and cross alleys need not be herein illustrated.

Each individual loom is comprised, as is usual, of loom sides 2 connected by the breast beam land suitable cross 'girths to form a frame which carries a driving shaft 3 for driving the lay L, the warp let off W, the replenishing mechanism R, cloth take up T at the front of the loom (see Fig. 2) and other usual component parts which need not or sometimes two shipper handles positioned at the .front of the loom. Such usual shipper handles, together with their connections to the clutch, have been employed in the present embodiment of my invention, as a matter of convenience. These shipper handles are illustrated at '7 and 8 on the drawings.

"The left hand shipper handle 7 is fixed to a shaft 9 j ournalled in bearings on the loom frame. The shaft 9 extends widthwise entirely across the front of the loom and the shipper handle 8 is fixed to the right hand and of this shaft. A depending arm 10 is fixed to, and moves with, shaft 9, preferably by being formed integrally with shipper handle 8. A link 11 has one end bent toextend loosely through an aperture in arm 10, being retained in the aperture by a cotter pin' 12. Link 11 extends rearwardly adjacent theoutside of the loom side and supports at its rearwardend a head'13 to which are pivoted levers 14 and 15 of a toggle. The outer end of lever 15 is pivoted to an arm 16 fixed to a block 17 which is, in turn, slidable axially of the clutch on a pin 18. Another arm 19, likewise fixed to the block 17, ex

tends rearwardly from the block to engage and operate the movable member of the clutch. It, is apparent that when either of the shipper handles 7 or 8 is pushed rearwardly toward the loom the clutchis disengaged andwhen the handles are pulled forwardly the clutch is engaged.

, As above intimated, I have added a third shipper handle 20 at the back of the loom for th'e'convenience of the. weaver. The shipper handle 20 is pivoted to the loom frame at 21 and is connected to the head 13 on link 11 by means of a link 22. Links 22 and 11 are sufficiently resilient, to bend slightly, if'necessary, to permit proper action of the toggle. It will thus be seen that I have provided ship per handles at both the front and the back of the loom with connections from each of them for operating the clutch, or, from another point of view all of the shipper handles are rigidly connected together and to the clutch whereby operation of anyone of the handles will operate the other-handles and the clutch. vIn order to prevent the inadvertent starting of the looms from the back alley I have provided means operable from the front of the loom for rendering the shipper handle at the back of the loom inoperative, the same consisting of a manually operable latch 23 carried by the front shipper handle 8. e

The particular form oflatch shown is comprisedof a more or less triangular wedge pivoted on the bent end of link ll where it passes through the aperture in arm 10 of'the front shipper handle 8. The aperture 24 in the latch is of a size to fit loosely upon the link end, whereby the latch is pivotally suspended from the arm '10. The portion 10 of the shipper handle 8, to which'the latch is pivoted, moves toward'the loom frame to engage the clutch and away from the loom frame to disengage the clutch. Thelatch member is of just the proper length, from aperture 24 to surface 25 of leg 26, to form' a wedge extending between the loom frame and the arm 10' of the shipper handle when the latter is in its position farthest remote from the loom frame, i. c. when the clutch is disengaged. The latch 23 may be manually rotated to this wedging position (see dotted lines'in Fig. 3) but is accessible only from the front of the loom.- However, when it is somanipulated it J effectively locks all of the shipper handles in off position.

Leg 27 of the latch 23 is slightly longer than leg 26thereof but has a surface 28 in the same plane as surface 25. Since the latter surface is normalto a line drawn radially of aperture 24 the surface 28 may be said to be eccentric of-the aperture. Therefore leg 26 and surface 25 form the wedge proper, which prevents movement of the arm .10 toward the loom frame, while leg 27 and surface 28 form a sto which prevents the latch from dropping own once it is rotated (clockwise in Fig. 2 or counter. clockwise in Fig. 3) to wedging position. The latchis, of course, released by manually'rotating it counter clockwise, Fig. 2 or clockwise, Fig. 3.

Other means may be employed for carrying my invention into effect and it is, therefore, to be'understood that detailed disclo-v sure of the preferred embodiment is for purposes of illustration only and not of limitation, the true scopeof the invention being defined in the appended claims. Y Iclaim: Y 1.
