LOOM.

Application filed April 15, 1926.

This invention relates to improvements in looms, especlally of the narrow ware class 111 which the shuttles are arranged in banks one 7 above another and the entire complement of shuttles, subject to the control of a pattern or equivalent mechanism, is moved up or down from time to time so as to discontinue the weaving action of the shuttles in one bank and start the shuttles in an adj oining bank to operate. Examples of looms of this type are afiorded by the Sohaum Patent #1278226 and my own Patent #1,498,396. Sometimes the structure including the several banks of shuttles is allowed to fall because of some fault in the mechanism which controls it, and when this happens, the loom otherwise continuing in operation, the result is disastrous to the warp and goods then in the loom, causing irreparable damage thereto and sometimes great loss. It is the object of this invention to provide automatic means for stopping the loom when said structure is thus allowed accidentally to fall.

In the drawing- Fig. 1 is a side elevationof sufficient of a loom embodying my invention to illustrate the latter;

Fig. 2 is a front elevation of an end portion of what is shown in Fig. 1, the shuttles being omitted; and

Fig. 3 is a fragmentary side elevation with parts of the loom projecting beyond the near side-frame in vertical section to show certain details of the invention more clearly.

In the loom-frame 1 are pivotally supported pairs of parallel links 2 which in turn pivotally support castings 3 which carry the lay or batten a. Only one side or side-frame of the loom-frame, one pair of links and one casting are shown, but it will be understood that there will be two or more of. each ac cording to the width, viewed from frontor rear, of the loom. The castings 8 have connected to them the pitmen 5 and through them, from the wheels 5* (only the near one being shown) on the main shaft 5 they are reciprocated forward and back substantially as usual in looms. As will appear, the object in supporting the batten structure 3% by pairs of pivoted links is always to maintain it in a vertical position in its forward and backward movement; this, however, is

also old in the particular type of loom to which the present invention relates.

A shuttle frame 6 is arranged to slide vertically in the batten structure. having in the present case top and bottom fittings S which are guided on the vertical rods 9 which may be regarded as parts of the batten structure. The shuttles are shown at 10 in two sets of superposed banks, in this. case there being two superposed banks to a set, or in other words, two superposed banks to each weaving plane 10*. The means for mounting them in the frame 6 and the means for reciprocating them toward and from the observer in Fig. 1, or laterally and horizontally in Fig.

2, are entirely immaterial to the present invention and may follow any well-known construction and operate in any well-known way.

The frame 6 is moved vertically from any suitable pattern or equivalent mechanism, as in the mentioned patents, a partof which may be afforded in the present instance by the member 11 which moves up and down when called and to which is connected, through a link 12, a lever 13 fulcrumed on a rock-shaft 14- and in turn pivotally connected with the frame 6 through the link-connection 15; so much of the lever 13 as is at the right of the rock-shaft in Fig. 1, together with link connection 15, will be duplicated at the far end ofthe loom in said figure, it will be understood, and such duplicate-lever, not shown, will of course he fixed to the rock-shaft 14. A spring 15 connects the member 11 with some fixed point 15 and serves to counterbalance the weight of those parts which are carried by the forward end of lever 13 and the mentioned duplicatelever at the far end of the loom.

As already suggested, sometimes in these looms the frame 6 assumes an abnormally low position, below that indicated by the dotted outline w in Fig. 3. The structure including frame 6 and the shuttles is quite heavy, and if some fault occurs in the pattern mechanism or in some part of the train connecting it with said structure the latter will fall. If the loom is at the time going and producing goods it invariably means a bad smash, involving destruction of the warp and woven goods and usually great loss to the manufacturer, especially if the loom is of large capacity. For the prevention of injurious action of the loom in such an emergency I provide means to stop the operation immediately as follows:

The gear on the main shaft 5 is in mesh with a pinion 16 on the drive-shaft 17. It is not material how this drive-shaft is driven, but in the present case it is equipped Withtastand loose pulleys 18 and 19 around which may extend a driving'beit 20: shift-able from one to the other pulley. The shifting of the belt is controlled by a belt-shifter 91 which is an upstanding arm on a rock-shatt- 22' journaled in the loom-frame and having at its forward end an upstanding arm 23 21, and being in efiect shipper lever; Arm 23"is engaged with the usualsl idahle bar 24 which is suitably guided: and extends across theiront oi the loom in convenient reach of the Weaver for starting; and: stop pi-ngt-he machine.

On a pi n25- in the frame ot the loom is fulcrumeddetent lever 26 which extends bet-Ween the batten. iii-11d the frame 6 its rear end being normally held elevated by a spring 27. In a bracket 28* projecting laterall'y' from the side frame is tulcrumed a trip lever 29 Whose upper end hunter 29* adapted when the trip lover moves to the right in Fig. 2 to strike the arm 23 of the shipper lever to shift the" same to the position for stop 'ain'g the loom. This moveincntoi the trip lever is effected by a spring 30 which coir ects its lower end tbel'oyv its fulcrum) with the bracket 28-. There is a 'paivl 3 1 pivoted to tlretrip lever andit is normally held by a spring 32, connecting it with the trip lever, so as to bear upvva-i cly against a' guiding: pin 33' which may project forward from: the loom frame (Fig. 3). This pa vl has a notch 3 1' in which it engages the tetent lever 26' Whenthetrip lever is shifted to the left in. and thus cocked.
