WILLIAM PILKINGTON, OF FRANKFORD, AND DOCTOR PILKINGTON, OF CHESTER, PENNSYLVANIA.

Letters Patent No. 66,734, dated July 16, 1867.

IMPROVEMENT IN STOP-MOTION FOR LOOMS.

To ALL WHOM IT MAY CONCERN:

Be it known that we, WILLIAM PILKINGIQN, of -Frnnkiord, and city of Philadelphia, and State of Pennsylvnnia, and DOCTOR PILKINGTON, of Chester, Delaware county, and State aforesaid, have invented a. certain new and usefnl'lmprovementin Filling Stop-Motion for Power-Looms and we do hereby declare that the following is a full, clear, and exact description of. the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure 1 is a top view. I

Figure 2 is an end view.

The other drawings in detail are as follow; (similar letters refer to like parts:) 7 i I Detail drawing 1; is a finger; c is a lever; d is a lever; e is a swell; f is a fiiling-forkg' ands is a right- .nngle lever.

Our invention belongs to that class of improvements called filling (or weft) stop-motion for power-looms, the nature'of which consists in arranging the wire filling-fork with a lever and finger, so thntthc belt will be shiftedhy the forward motion of the lay, and thereby stop the loom when the filling is exhausted or broken.

To enable others to make and operate our improvement, we shall describe its operation and construction, reference being had to detnil drawings, as specified. i

The filling-forkfis hung on the stud in the right-angled lever s. Said-levers is. hung on a'stnd fastened to the breast-beam B, fig. 1. The'lower end of said. lever s has a slot, through which is passed the finger b, one end of which finger is fastened to the lever d. The finger b and lever 01 are connected by n'ball-and-socket joint,

I (see details.) The lever 01 ispivoted by means of a belt or screw to the breast-beam in front of the protecting lever g, against which it operates. On the sword of the lay is a casting or stand, a, in line pgth the finger-b. On the end of the lay where the filling-motion is placed is a small lever, a, below the swell. e, connected by the pin or .stud 1, fitting the hole 2, (see detail and fig. I.) The filling-fork is sunk below the racebonrd and guided by the filling-grate, which grate is constructed and fastened 'to the lay inthe usual manner.

7 The operation is as follows: When the filling is exhausted or broken, the filling-fork is left behind and fails tolift the finger 6,'and es the lay advances, the standa on the lay sword comes in contact with'the finger b and is forced forward, which operates the lever 11, and said lever d operates lever g, which unlocks the belt-shifter and stops the loom. When the filling is not exhausted or broken, the fork .f will 'causethe lever s to lift the 'finger c and pass the stand a as the lay advances. When the shuttle leaves the box, or is in th'c other end of' the lay, and the swell is'pressed in the box by the ordinaryv swell-spring, the swell e will force out one end of lever c, and as the lay advances it will come in contact with'the stud on the lever s, on which is hung the fork f, and cause the finger to clear the stand a the same as if the filling was across the grate.

"Claim.

1. We claim the combination of the fork f, lever B, finger c, and stand a, constructed and operating as and for the above-described purpose, 7

2. We claim the combination of the swell a, lever c, and lever 43, as and for the above-described purpose.
