IFELECTRIG STOP-MOTION.
have invented a new and Improved Electric Stop Mo tion, of which the following is a full, clear, and exact description.
The invention relates to looms, and its object is to provide a n ew and improved electric stop motion, arranged to automatically stop the 100111 in case a warp thread breaks, the action taking place by connection with the ordinary stop motion actuated when the weft filling runs out or breaks.
The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.
A-practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of-r ef ence indicate corresponding parts in all the view Figure 1 is a side elevation of the improvement as applied; Fig. 2 is an end elevation of the same; Fig. 3 is an enlarged sectional side elevation of the improvement; Fig. 4 is a plan view of the same, and Fig. 5 is adiagrammatic perspective view of the improvement.
The loom A on which the improvement is shown applied is of the usual construction, and is provided with a stop inotion B having afilling fork .C controlledby the filling, and fulcrumed on a slide D, for actuating the re-- leasing latch E engaging the shifting lever F, for throwing the latter out of the notch F in a slotted keeper F whenever the filling runs out or breaks, it being understood that the said shifting lever F is pressed on by a spring F and carries the shifting fork F for shifting the driving belt G from the fast pulleyG to the loose pulley G both pulleys being mounted on the driving shaft H of the loom.
When the filling runs out or] breaks, the filling fork C is engaged and bodily shifted by the arm I of the weft hammer I, continually oscillated by a cam I secured on the shaft H.
The mechanism so far described is of the usual construction and operation and hence further description of the saine is not deemed necessary, it being understood, however, that when the filling runs out or breaks,
the filling fork C is actuated to cause the latch E to Specification of Letters Patent. Application filed-June 27,1906. Serial No. 328,733.

above the warp beam K, as plainly indicated Fig. 1. Each thread guide L is preferably made of spring wire,
, secured at its middle to the bracket N and provided at both ends with eyes L, L for the entrance and exit of the warp thread. Each thread guide L is also provided with contacting arms L L, adapted to make contact with opposite sides ofa rod 0, held in bearings O of rubber or other suitable insulating materialattached to the bracket N. The rod 0 and the bracket are connected by wires P and P with an electro-magnet Q,
' secured or formed on the arm I of the weft hammer I so that when the electro-magnet Q is energized, as hereinafter more fully described, it then attractsthe filling fork C to hold the same in engagement with the arm I of the weft hammer I, to shift the filling fork C bodily,
thewire also connects with a circuit breaker R, having spring arms R, R attached toopposite sides of an insupulley G then the block Rpasses between the arms R and B, so as to break the circuit for the electro magnet Q after the'belt G has been shifted from the fast pulley G to the loose pulley G v The operation is as follows: When the loom is running, I
the warp threads J passing through the eyes L, L hold the arms'L and L of the thread guides L out of engage:
ment with the rod 0, and consequently the circuit for the electro-magnet Q is broken and the electro-magnet is in a denergized condition. Now, in case the warp thread I breaks, the thread guide L is releasedand by its resiliency causes the arms L, L tomove in contact with the rod 0, so that the electric ,circuit for the electromagnet is:closed and consequently the electro-magnet Q is energized. Now as the electro-magnet Q is in close proximity to the filling fork C, it is evident that the filling fork is attracted and thrown in engagement with the arm I of the weft hammer I, so that the filling fork C and with it the slide is bodily shifted, for the releasing latch E to release the lever F. When this takes place, the shifting lever F shifts the belt G from the fast pulley G to the loose pulley G 'to stop the loom, and at the same time the block It again breaks the circuit by separating the spring arms R, R so that-the electrical energy of the source of supply Q is not wasted to any extent. 4
The device is very simple and durable in construction and can be readily attached to looms'having stop mot-ions as described, and it will also be noticed that the circuit closer, consisting of the thread guides L and rod 0, is completely out of the way of the leash rods,
heddles and other devices of the loom.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A stop 'motion for looms, comprising a stop motion controlled by the filling and having a filling fork and a weft hammer, an electro-magneton the said weft hammer for attracting the's'aid filling fork, and means controlled by the warp and electrically connected with the 'said electro-magnet.
2. A stop motion for looms, comprising a thread guide for the passage of a warp thread, a contact adapted to ,be engaged by the said guide, the latter being normally held out of engagement with the said contact by the warp thread, an electro-lnagnet electrically connected with the said thread guide and the said contact, a weft hammer carrying the electric magnet a belt shifting, device and a shifting member for the belt shifting device adapted to be attracted by the said'clectromagnet when the latter is energized on the breaking of a warp thread.
3. A stop motion for looms, comprising a thread guide for the passage of a warp thread, a contact adapted to be engaged by the said guide, the latter being normally held out of engagement with the said Contact by the, warp thread, an electro-magnet electrically connected with the said thread guide andthe said contact, and a belt shifting device, comprisinga belt shifter, a locking device for the same, a releasing device for the belt shifter, 11 iilling fork for actuating the said releasing device, and a weft hammer for actuating the said filling fork and carryingthe said eleetro-magnet for attracting the filling fork.
4. A stop motion for looms, comprising a thread guide for the passage of a warp thread, a contact adapted to be engaged by the said guide, the latter being normally held out of engagement with the said contactby the warp thread, and electro-magnet electrically connected with the said thread guide and the said contact, a weft hammer carrying the electric magnet a belt shifting device, and a shifting member for the belt shifting device adapted to be attracted by the said electi'omagnet when the latter is energized on the breaking of a warp thread, and a circuit breaker controlled by the said oscillating member to break the circuit for the said electro-magnet.
5. An electric stop motion for looms, comprising a stop motion having a filling fork controlled by the weft and a weft hammer for shifting the filling fork, an electromagnet on the said weft hammer for attracting the said filling fork, and a circuit closer for the said elcctro-mngnet and controlled by the warp to energize the said electromagnet on a break in the warp.
In testimony whereof I have signed my name to this specification in the presenceof two subscribing witnesses.
