Description
June 13, 1933. J. LOEFFLER ANNUNCIATOR SIGNAL Filed Jan. 5, 1931 iNVENTOR Lamb JLmfflw BY H as ATTORNEYS Patented June 13, 1933 y UNITED STATES PATENT OFFICE LOUIS J. LOEFFLER, OF STAPLETON, NEW YORK ANNUNCIATOR SIGNAL Application filed January 5, 1931. Serial No. 506,672.
This invention relates to that type of ancasing is suitable for housing a single annunciator in which a signal is communicated nunciator unit which is inserted into the casto a person at a distance by means of a visual ing from the rear, and by removing the screws disk which is oscillated to a predetermined 15, it can be easily removed. There can be position to attract the persons attention, and any number of independent units mounted on reset to its normal position by means of a the panel, although the description of one reverse movement of the disk. will suffice for the other.
The invention is designed to provide means In the casing is enclosed an iron frame 16 for rotating the disk in an arc of a circle to having a front portion 17 with a series of its initial or set position and retrograding it sight openings and a bifurcated rear portion by means of an independent circuit. 18 constituting a pa1r of electromagnetic pole An object of the invention is to provide a members. An electricbobbin 19 is wound on pair of electromagnets, one being energized each of the pole members and leads 20 conto set the disk initially and maintain it in nected to a source of electric energy control that position until the current is applied to the energizing of the bobbins. The circuit is 65 reset or reverse the disk. In adevice of completed by the return wire 21 connected this kind the self-contained electric reset to the frame. I j signal requires but one-fifth of a rotation of To the bottom of the pole members is sethe disk to reset or reverse it to its normal cured by means of screws 22 a disk 23 of inposition, thereby requiring a very low cursulating material having centrally mounted rent consumption due to its shor t oscillation. thereon a rotorshaft 24 with an indicator One of the novel features contained in this comprising a visual disk 25 fixed to its upper signal is that it does not rely on gravity to end. The disk has white coloring to denote keep it in its respective position, but is acwhen it is in register with the openings and 25 complished by means of a spiral spring the black coloring intermediate to show when the stem or point of which rocks on the axis of disk is moved to the sight openings. The the shaft controlling the visual, and once rotor shaft is equipped with an armature 26 pulled over by the electromagnet is kept in having upturned ends and studs 27 form that position at either set or reset. stops to prevent excessive movement of the 30 The novel features of the invention are armature. The armature has anotched insumore fully described in the following specifilating washer 28, and a spiral spring 29 with cation and claims, reference being made to one end secured to an arm or support 30, and the accompanying drawing in which: the other end wiping in the notch coacts to I Figure 1 represents a horizontal, longituposition the armature.
" dinal, section taken along the line 22 of The position of the spiral spring is shown 85 Figure 3 of a device embodying this invenin Figure 4: after the visual has been reset, tion. and in Figure 5 it shows the position of the Figure 2 is a vertical, longitudinal, section spring with the visual set. The notched taken along the line 1-1 of Figure 3. Washer allows the spring to rock or move Figure 3 is a front elevation of the same. from right to left, the free action, however, 90
Figure 1 is a transverse section taken along is held in check as to its lateral movement. the line H of Figure 1. The spring acts as a check to compensate for Figure 5 is a similar view showing the the sudden pull of the magnet on the armaparts in a different position. ture transmitting uniform oscillation to the In the drawing the numeral 8 designates visual disk and preventing rebound after 5 a panel having a name plate 9 fastened to it, the end of its stroke. and a sight opening 11 covered with a glass The armature, as shown in Figures 4 and 5, disk 12 inserted in the opening. The panel is in the form of two arms extending from has a tubular casing 14 fixed adjacent the the axis of the rotor and by energizing the opening in the rear of the glass disk. The left hand magnet the armature 1s pulled in the direction of the arrow as indicated in Figure 4 setting the visual disk, but when it is desired to reset or reverse the disk the opposite arm is attracted by energizing the right hand magnet, thus pulling the arm in the direction of the arrow shown in Figure 5.
What I claim is An annunciator signal comprising an open ended cylinder, a unitary element adapted to be inserted at one open end of and contained within the cylinder and comprising a mem her at one open end of the cylinder and a pair of arms extending rearwardly of and perpendicularly to said member, the free ends of said arms being turned inwardly and then back upon said arms and spaced therefrom, an insulating disc mounted at the bends in said arms, a coil mounted on the free end of each of said arms, a rotor shaft having one end journalled in the center of said member extending rearwardly between said coils and having its other end journalled in said insulating disc, an armature comprising a pair of oppositely disposed arms mounted on said rotor shaft, each of said arms lying adjacent one of said coils, and a second member fixed to said rotor shaft adjacent said first mentioned member, said members including means whereby a signal 1s given when the second members position is changed with relation to the first mentioned member.
In testimony whereof I have hereunto set my hand.
