WILLIAM wATTin, or. wononsrnn, MAssAcnUsnTTsnssIeNoR TO cnoiur ronl &

To all whom it may concern? 1 a Be it knownthat I, W AM WATTIE, a citizen 1 of the United States, residing at WVorcester, in the county of Worcester and 5 State. of Massachusetts, have invented cerwhich the following is a specification.

My invention relates to a vibrator lever, and a vibrator connector, which form a part of the well known Knowles head motion for shuttle box and harness shedding mechanism a l of looms, shown and described in U. S. Rey issue Letters Patent, No. 7 ,784. i

l My invention particularly 1, relates to an improved construction of the vibrator lever, and vibrator connector. The vibrator lever,

and vibrator connector referred to,are ordinarily made of malleableiron, with the bosses and forked ends cast thereon, and must be made quite thin inorder to take up as little room as possible, and consequently 15 upon the construction of the vibrator lever, and vibrator connector above referred to.

, My improved vibrator lever, and vibrator connector are made of sheetmetahprefer the desired shape, without the studs or bosses, and the reinforced part formed thereon; said studs or bosses, and the reini forced part are made separate and r1g1dly connected with the vibrator lever, and vibrator connector, to be practically integral therewith, by welding. e

I have shown in the drawing a detached part of a Knowles head motion of the type referred to, comprising avibrator lever, a

shown in Fig. 2, looking in the direction of arrow a, same figure, with the bosses and the patch :p1eces thereon, preparatory to being welded. F1g8 shows the blank from which the vibrator connector shown in Fig. 1 is made. Fig. 9 shows ablank for the reinforced slotted end of the vibrator connector-P Fig. 10 shows a boss orstud for the attaching end. of the vibrator connector. Figfill is an edge view of the vibrator connector, looking the direction of arrow 5, F iggS,

with the boss and reinforced slotted end thereon, preparatory to beingwelded.

In the accompanyingdrawing, 1 is the vibrator lever blankpcut or stamped out of sheetmetal, havmg inthis instance a pat tern run 2, made separate therefrom and riveted thereon, on its lower edge, in the usual way. A boss or pivot stud 3, see Fig.

1, is secured upon the blank 1, and carries,

loosely mounted, to have a reciprocating or rocking movement, a vibrator gearll. The gear 1 has a curved slot 4: therein, to receive a boss 5 on the vibrator lever 1. e e i G is the vibrator connector, which is pivotally attached to the vibrator gear 4 by the boss 7 all in the usual and well known way. I, will now describe my improvementsuin vibrator lever, and vibrator connector above referred to.

1 The vibrator connector 1 is first prefer ably punched or cut out of sheet metal, preferably steel in the shape shown in Fig. 2,

having the open end slot portion 1, to which isto be attached the boss piece 8, Fig.1 3, of.

corresponding shape. The boss piece 8 is attached to the blank 1 at 1, as shown in Fig.7. A bar or piece 9, Fig. 4,.is also to be attached to the blank 1, near the open end slotted portion 1",.as shown in Figs. 1 and 7.. The opposite end 1 of the blank 1 re Fig. 1, are located. The bosses 3 and 5 con-' sist of a hub piece 11, shown in Fig. 6,

which is provided with the reduced end 11',

adapted to be inserted into the bore 1, or 1".

The blank 1 is held in a suitable device,-

with the separate bosses and pieces in place thereon, and each separate boss and piece on theblank 1 is welded to said blank,

and the vibrator'leve'r then appears as if" same manner as the vibrator lever 1, above described. The blank'6 is punched or cut" outof sheet metal, preferably steel, in the shape shown in Fig. 8, with an open end slot 6 at one end. The offset reinforced end piece 12,-see Fig. 9, with an open end slot 12 therein, is made in this instance separately, to be attached to the blank 6. The hole 6 in the blank 6, in the opposite end thereof,'is adapted'to ,receivethe reduced end on the hub piece 13, see Fig. 10, which is similar to the bosses 5 and 6, attached to the blank 1 of the vibrator lever.

The boss 13, and piece 12 on the vibrator connector blank 6 are welded to the blank 6, and the vibrator connector then appears and are of greater strength and rigidity than the ordinary malleable iron vibrator;

. ,sheet metal.

lever, and vibrator connector. It will be understood that the details of construction of my improved vibrator lever, and vibrator connector may be varied if desired.
