L ONE-ALARM.
Specification of Letters Patent.
Patented June 27, 1916.
Application filed January 11, 1915. Serial No. 1,488.
To all whom it may concern:
Be it known that I, ANTONIO MARCANTE, a subject of the King of Italy, of. the city of Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Loom-Alarms, of which the folhis invention relates to an indicator mechanism for looms of the class adapted to ring a bell, light lamps or otherwise indicate the presence of trouble in the warp threads before the yarn is broken, and the object of the invention is to provide simple and eflective means whereby a member located in the path of travel of the warp threads is arranged to be engaged and moved by a snarl, entanglement, or other irregularity in these threads to cause an indicator to denote the presence of trouble in the warp before the yarn is broken.
\Vith these and other objects in View, the invention consists of certain novel features of construction, will be more fully described, and particularly pointed out in the appended claims.
In the accompanying drawings: Figure 1 is a diagrammatic view illustrating the general arrangement of a narrow ware loom and my improved indicating apparatus as connected thereto. Fig. 2 is a rear elevation showing a portion of the yarn feed, and a portion of the circuit-closing bars in normal position. Fig. 3 is the same as Fig. 2 showing the ends of the circuit-closing bars as moved into position circuit and cause the alarm. Fig. l is a detail in perspective illustrating the crossing warp yarns, the tilting circuit-closing wires extending into the path of travel of said yarn and the operating cord which is arranged to be engaged by a snarl or entanglement and moved by the travel of the threads against the circuit-closing wires. Fig. 5 is a view of one of the circuit-closing wires. Fig. 6- is a view of a modified form of a circuit-closing wire having a double engaging end adapted to be operated by either one or both of two dilferent sec tions of the moving warp. Fig. 7- is a perspective view of a portion of the circuit closing bar showing the loop in the end thereofadapted to engage the exposed portion of the wires and close the circuit.
Referring to the drawings 10 designates the ground warp beam and 11 the figure and resident" of current 26 to a to close the electric" warp beam, both of which are passed through the loom in the usual way. The figure warp (6 passes over the guide roll 12, weight roll 13, guide roll 14 back around the guide roll 15 whence it joins the ground warp thread I) and-is crossed between the lease rods 16 and 17 on their way through the harnesses 18 and lay 19 to be woven into the fabric at 20 and passed over the breast beam 21 to be subsequently wound upon the take-up roll 22.
My improvement contemplates the provision of means whereby when a knot, snarl, entanglement or other irregularity occurs in thewarp threads, to automatically notify the attendant so that the same may be corrected before the yarn has become broken and so save much time in piecing up and also eliminate objectionable knots being made in the warp threads of the fabric. In order to accomplish this in a simple and effective way, I have provlded an electric circuit in which is connected an upper contact bar 23 and a lower contact bar 2 1 both of which are connected by wires 25 through the source bell 27 or other sound producing indicator or to a lamp 28 or other visible indicators. On this upper bar 23 I have pivotally hung a plurality of circuit closing wires 29, which may be spaced apart or arranged at intervals along this bar throughout the width of the warp threads.
One leg 30 of each of these wires extend up between and into the path of travel of the warp threads while the downwardly projecting 13 31 of these wires extends down from the pivot bar 23 adjacent the lower contact bar 24, whereby when a snarl occurs in the moving warp, one or more of the upper ends of these wires is carried forward and the lower end 31 is consequently brought back in contact with the bar 24L thereby closing the circuit between the two and causing the indicating mechanism to be actuated.
In some cases a second set of wires 34 may be hung on the bar 32 to be operated the same as those above described to be tilted on this contact bar and complete the circuit through the lower bar 33. As many series of these wires as desired may be employed along the warp threads, but it is desirable to position one set in front of each lease rod where a snarl would be most likely to cause a thread to be broken.
It is found in practice very desirable to and 37, and bar 36 roll will as the warp :through which this figure to travel and if a snarl occurs in the warp open warp threads, whereby when a snarl occurs this flexible cord is first engaged by the same and moved to press against the wires and so close the circuit. By the use of this cord I am enabled to dispense with many of the wires, which'would otherwise be necessary in order to cover all of the separate threads in the warp. In this way it will be seen that when a snarl or entangle ment occurs in any portion of the warp it wires to close the circuit and sound an alarm or light a lamp or both.
Another feature of my present invention is the provision of circuit-closing bars 36 being positioned above whereby if the figure sufficiently the weight is fed along engage the bar 36 normally resting on the pin 43 and raise the same so that the loops 37 and 38 will be moved from the insulated portions 39 of the circuit wire 0 and close the circuit to sound the alarm or light the lamps. The lower bar 37 is shown as being flexibly supported on springs 44 and provided with a laterally arranged series of pins 10 warp or is caused the weight roll 13, warp is not let off its passage through these pins would be prevented and would cause the bar to move downward so that its loops ll and 42 would move from the insulated portions 39 toengage the circuit wires 0 and so operate the necessary alarm.
In some cases it is found desirable to construct a circuit-closing wire in the double form as illustrated in Fig. 6 in which I have provided two arms 45 and 46 which may be arranged to engage and be operated by two different sections of the warp yarn, instead Copies of this patent may be of said members and move the tact bar, a series of a single section as is the case of the single wire.
I claim:
1. In a loom, an electric circuit, an indicator', a series of circuit-closing members extending into the path of travel of the warp and supported independent of the yarn, means whereby a snarl in the moving warp causes one or more of said members to affect said electric circuit and operate said indicator to denote the presence of trouble before the yarn breaks. is caused to operate some of these tilting' 2. In a loom, an electric circuit, an inclicator, a series of circuit-closing members extending into the path of travel ofthe warp and supported independent of the yarn, a flexible cord extending along said members whereby a snarl in the moving warp causes said cord to engage one or more upon said electric circuitand operate said indicator to denote the presence of trouble before the yarn breaks. 7
3. In a loom, an-electriccircuit, an indioator, an upper contact bar,.a lower conpivotally supported on said upperbar and having a portion extending into the path yarn and a portion of travel of the warp extendlng to a polnt bar, whereby a snarl in adjacent said. lower the moving warp is caused 'to move said members into engagenent Wlth'SLlCl lower bar to affect the electo detric circuit and operate an indicator note the presence of trouble before the yarn breaks.
In testimony whereof I affix my signature inpresence of two witnesses.
