ooM'BInED SHUTTLE GUARDAND sues Mormon.

A pplieation area May is,

My present invention relates to improvementsin combined shuttle guard and stop motions for looms of the single threadqvarp and single fork type utilizing cams on the auxiliar shaftand as shown in U S. Patent to Wood: No; 823,248, of June 12, 1906. As is well known in the weaving art the stop- ,motion includes a filling fork which is arranged on the breast beam in connection with in means that control the driving motion of the loom, and the fork is normally retained in such position that it will touch the control means. If however the shuttle passes without leaving a filling thread, or for other well known reasons,; the :fork having nothing to retain it away from the control means, comes 1n contact therewith, and immediately stops the operation of the loom.- In carrying out my invention I employ in connection, with i 2 the reed cap of the loom,- a spring actuated,

normally held, brush bolt, adapted to be pro= jet-ted into position for co-aetion with the tail of a side fork such as is shown in the said patentof Wood, for the purpose of automat- 25 ically stopping the loom through the control of the driving mechanism.-

The spring actuated brush-bolt is released upon the operation of a push bar or rod extending longitudinally of and suspended so from the reed-cap, and means are provided for restoring the bolt or re-setting the stop motion, as will hereinafterbe more fully set forth and claimed.

The initial movement of the raising of the push rod to initiate the stopping of the loom V is caused by the shuttle in flight over the float contacting with the push rod and elevating it to cause release of the slide bolt. The slide bolt is then projected by its spring to the po sitionof Figure 2 with its brush in the path of the filling fork that is engaged by connections (including a hook) from the auxiliary cam shaft. The brush holds the fork against movement, and as a result, the hook of the cam connection engages the tail of the fork, thereby stopping the operation of the loom.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention wherein the parts are combined and arranged according to the best mode I have thus far devised for the practical application of the principles of my invention.

Figure 1 is a view in elevation showing sufficient of a loom to illustrate the relation 1927. Serial No. 191,724

thereto of the stop-motion of my invention, the latter being in locked or normal position. Figure 2 is an enlarged,- fragmentary view in front elevationshowing the bolt sprung, or projected to position for co action with the filling fork.

Figure 3 is a sectional view at line 3-3 of Figure 2 of the reed and reed-cap, the push gap, and also the detent or pawl for the spring Figure 4E- is a view from the rear of the reed-cap showing the brush bolt in locked position,

In order that the general arrangement and relation of parts may readily be understood I have indicated in Figure 1 some parts of the loom as the frame D, the harness frame H at the front of which the reed cap Alind reed A operate in usual manner, and the filling fork in Figures 1 and 2, indicated as F, is designed to be moved forward,- of the loom, as the reed-cap swings or oscillates in usual manner, when the parts are set to stop the loom. lVhen the tail of the filling fork is in its depressed position the fork encounters the usual or well known type of hook to stop the driving mechanism of the 100111.

The reed-cap carrying the reed A is of usual type, fashioned of wood, and extends longitudinally of the loom, and operates in well known manner. On the front beveled faces E of the reed-caper bar A the stop motion mechanism is carried and actuated or operated through the upward movement, as pressure is applied thereto, of the longi tudinally extending push rod 1. This rod is located below the bottom of the reed-cap and in front of the reed, and is provided with upwardly bent ends 2, 2 that are suspended in the vertically arranged brackets 3, 3, spaced apart and attached to the reed cap. Cotter pins 4 ends 2 of the rod, and supported on the upper faces of the brackets for the purpose of suspending the push rod in front of and below the reed-cap. The push rod may be moved vertically, or pushed upwardly in its bearing bracket-s 3 against the tension of a pair of springs 5 that are coiled aboutthese vertical ends and interposed between an anchoring pin 6 passed through theend of the rod and the upper flange of the bracket 3. Thus when the rod is lifted against the tension of the springs, it is returned afterward, to normal position by the springs.

are passed through openings in the push rod 1 is to or rigid with a rock-rod 10 that is jour- V naled in bearings 11 on the beveled face E of the reed-ca p. As the upward pressure on the push rod elevates said rod it will be apparent that this rock-rod will be rocked in its bearings. t one end the rock rod is fashioned with an angularly disposed detent 12 which (to-acts with the spring actuated brush-bolt 13 having at one end the tuft or brush 14:. The brush-bolt extends longitudinally ot the reed-cap and is supported therefrom by means of a bracket 15 secured to the beveled face of the reed cap. At 16 one end of the brush bolt is notched to form a hook, and it will be apparent that this spring actuated brush-bolt is designed to be retained in inoperative position or in normalposition, by the engagement of the rock detent 12 with the book 16. To lock or latch the detent and hook, pressure is applied to the push rod to elevate it and thus swing or rock the rock rod 10 and swing the detent outwardly from the reed cap to permit movement to the right in Figure 2 of the brush bolt. As thehook 16 reaches the position for engagement of the detent, pressure is released from the rod 1 and the detent is swung into the hook, thus holding the brushbolt. It will readily be seen that when the again elevated. the detent will be swung outwardly and released from the brush bolt or its hook 16. A spring 17 is coiled about the bolt and located between a fixed washer 18 on the bolt and one of the flames of the bearing bracket 15, for projecting the brush bolt into position for co-action with the fork F as indicated in Figure 2, and a handle 19 may also be aiiixed to the slide bolt for sliding it to position for engagement with the detent.

Having thus fully described my invention what 1 claim as new and desire to secure by Letters Patent is 1. In a loom the combination of the reedcap and a side filling-fork, a normally retracted brushbolt carried by the reed-cap for co-action with the tail of the side filling fork, retaining means for the brush-bolt and means for relea g said rctainingnieans, and means for projecting the released brush-bolt.

2. In a combined shuttle'guard and stop motion for a loom the combination with a side'filling-tork and reed-cap, of a spring pressed, norn'ially retracted brush-bolt carried by the reed-cap, a pnslnoperating means a detent forming part of the puslroperating means for retaining the brush-bolt, and means 7 for actuating the push-operating means whereby the bii'ush-bolt is pro ected to pos1- tion for co-action with the tail of sald side filling fork.

3. In a shuttle guard for a loom, the combination with a side filling-fork and the reedcap, of a spring pressed brush-bolt carried by the cap, a push rodhaving a spring sus pension on said cap, a rock rod and means thereon for retaining the brush-bolt, and actuating means between said push-rod and rock rod whereby the bolt is projected into position for co-action with the tail of the r'ork.

1; The combination in a shuttle guard de vice with the reed-cap o'ta brush-bolt and an actuating spring therefor, and a hook on said bolt, 01:- a push-rod and spring suspension thereto]: on the cap, a rock rod journaled in brackets on the cap and a detent thereon tor coaction with said hook, rock arms rigid with said rock rod, and rigid actuating arms on the push rod having pivotal connection with the rock arms.

In testimony whereof I hereunto affix my signature.
