Specification of Letters Patent.
Patented June 5, 19 36.
Application filed April 18, 1905. Serial No. 266,804.
To ctlzl whom it concern:
Be it known that we, JOHN ConBIsHLnY, Josnrn H. W001), and TIMOTHY F. CoLLiNs, citizens of the United States, residing at Fall Bivenin the county of Bristol and Stateof- Massachusetts, have invented certain 'new and useful Improvements in Stop-Motions for Looms, of which the following is a specification.
This invention relates to looms; and its object is to rovide means for automatically stopping t e loom in case a heddle-strap breaks. As is well known, the heddles are raised and lowered by 'means of straps pass ing over pulleys, and when one of these straps hreaks, as it sometimes does, the fgbric that Looms are usually provid with two stands, one at each end, to catch the heddles when they fall. On these stands we place levers normally held in a raised ositionb oounterweights or the like, but a apted to e depressed when the heddle drops on them, and thereby close an electric circuit controlling the electric stop-motion of the loom.
In the accompanying drawings, Figure 1 is a front view of a loom-frame equipped with our invention. Fig. 2 is an end View of one of the stands with our stop-motion circuitcloser thereon.
The frame of the loom is represented two uprights l and a cross-bar 2. The hed die 3 is shown as suspended by two stra s or cords 4, passing over the pulleys 5. llhder each end of the heddle is a stand 6, having a wide head to extend under all the heddles, of which only one is shown in each figure of the drawings. Parallel with the upper edge of each stand we arrange a lever 7 fulcrumed at one end and provided with a counterweight 8 or the like to cause its free end to rise normally against a stop, preferably an arch 11, of sheet metal, attached to the stand and extending over the lever. A rod 9 extends across from one stand to the other, but is insulated therefrom by bushings 10, of insulation, at the points where it is supported in the stands. The rod is so located that when the levers are depressed they will come in contact with it, preferably through a iinger 12, projecting downwardly from each lever. One pole ofthe electric battery 13 i connected with the loom 'frame and the stands. The other is connected with the rod 9 through the electromagnet ll of the stopmotion of the loo-m and the alarm 15.
The operation is as follows: Normally the levers stand in the position shown. in the drawings, with their fingers out of contact with therod; but if a heddle-strap hrcalzs that end of the heddle drops on the lever below it and depresses said lever until the lin. ger thereon strikes the rod, which closes the circuit of the battery. This energizes the electromagnet 14 and trips the lever 16, which forms part of the controlling niocl'ianism of the loom, causing it to stop. At the same time the alarm notifies the attendant that something has happened.
Having thus described our invention, what we claim is 1. The combination with a loom equipped with an electric stop-motion, of a stand he neath each end of the heddles, a lever pivotsaid levers normally in a raised position, arod below said levers sup orted at each end by but insulated from tlie stands, and circuit connections between said stands and rod and the stop-motion. i
' 2. In a loom equipped with an electric stop-motion, the combination with the stands having wide heads, of the levers pivoted to said stands and having counterweigl'its, stops 'for the free ends of said levers, a finger on each lever, a rod beneath said fingers insulated from said stands, and circuit connections from said stands and rod to the stopmotion.
In testimony whereof we have signed our names to this specification in the presence of two witnesses.
