SPEGIFIGA'IION formingpart of Letters Patent-No, 622,498, dated April l, 1899.

llpplioetioniiled August 31, 1898.- Berlsl No. 689,936. N modeL) To all whom it may concern.-

Be it known that l, Cnms'rmu KRAMER, a citizen of 'Germany, residing at New York, borough of Bronx, State of New York, have in vented certain new and useful Improvements in Alarm Attachments for"-lower-Looms, of which the following is a specification.

This invention is intended to'supply an alarm attachment for power-looms, so that whenever one of the shafts of the same drops an immediate alarm is given, so that the attendant can stop the loom and look for the cause of the interruption and repair the defeet before any imperfect goods have been made, which would naturally be the case if the loom continues, and thereby save labor and material. i

The invention consists of 'an alarmattachment for power-loomswhich is actuated in case any one of the shafts is dropped, said attachment consisting of one or more springwire frames located transversely below said shafts and composed of a stationary guide portion having eyes and a yielding spring portion that is depressed so as to close an electric circuit whenever one of the shafts drops for one reason or another, soas to ring an alarm and call thereby the attention of the attendant to the defect, so as to stop the loom.

The invention consists, secondly, of the special construction of the alarm attachment, which will be fully described hereinafter, and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a front elevation of a ribbon-loom with my improved alarm attachment shown in position thereon, and Fig. 2 is a perspective view of oneof the attachments and the electric conducting-wires arranged in connection therewith.

Similar letters of reference indicate corresponding parts.

' Referring to thcdrawings, A represents the supporting'frame, and B the shafts, of a ribbon-loom of any approved construction. On

the longitudinal beams a of the frame A are arranged below the shafts 13 one or more wire alarm attachments C, which are formed of two upright wires 01, having horizontal guide-eyes d and a V-shaped wire (1 that is attached at one end to the longitudinal beams of the supactuated by the same.

porting-frame A. The free ends of the V- shaped wires (1 are, connected transversely below said eyes d by a wire (1" and in addition thereto by a transverse stiffening-wire d" at the apex of the V-shapedwires, as shown in Fig. 2. The V-shaped wire frame has a certain spring action, so that if one of the shafts should become disconnected and drop down on the transverse wire of the attachment the latter will move in the guide-eyes in downward direction, bending on the fastening ends until the lower transverse portion-comes in contact with the electric conduetingwires 0 c, that run along the face of the longitudinal beams on and form connection with the poles of a battery E, so that an electric alarm l) is The battery may be located at any suitable position near the loom,

so as to be called into action as soon as the circuit is closed by the lower end of the trans-- verse lower portion of the wire f ramc, as shown in dotted lines in l igi 2.

The alarm attachment enables the attendant of the power-loom to immediately repair any broken cord or other defect connected with the operation of the shafts without waste of time and material h' etoforc connected with such accidents. Tl.

cell is rung as soon, as any one of the shafts falls down, for the reason that the-alarm attachment is lowered and placed in contact with the electric conducting-wires of the circuit, so that the alarm is rung and the attention of the attendant drawn to the fact that the shafts of the loomare not in good working order.

He then knows that he has to immediately stop the loom and repair the do feet before further dam age occurs. He is thereby enabled to save considerable in time and material, as the imporfect part of the goods, which would naturally have been made if the loom had continued 4 running with one or more shafts out of: place,

would have to be undone again, the material 1 being wasted and time lost by this operation.

Having thus described my invention, I claim as new and desire to secure by Letters 1atcnt- 1. The combination, with the frame of a power-loom, and the shafts of the same, of a wire alarm attachm out extending transversely across thc'framc of the loom below said shafts,

and an electric circuit closed by saidalarni' attachment when one of the shaftsdrops on the same, substantially as set forth.

2. An alarm attachment for power-looms consisting of a V-shaped wire frame located below the shafts and attached at one end to the supporting-frame of the -l00m and pro-v vided with a transverse connecting-wire at' the ends of its V-shaped reds, guide-eyes for the free ends of said V-shaped rods, and an electric circuit closed by. the dropping of a. shaft upon said wiroframe, subst-antia'ilyas set forth;

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

' CHRISTIAN KRAMER.
