Application May 16, 1945, Serial No. 594,125
fire extinguishing equipment, and which signal 7 upon breaking of the seal will be moved into its indicating position.
A further object of the invention is to provide locking means for the flag to prevent return of the same to its concealed position, except through the use of a special key provided for such purpose.
A still further object is to provide a device of this character of simple and practical construction, which is eflicient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure 1 is a front elevational view.
Figure 2 is a vertical sectional view showing the signaling flag in its concealed position.
Figure 3 is a similar view showing the flag in its exposed position. T
Figure 4 is a transverse sectional view taken substantially on a line 4-4 of Figure 3.
Figure 5 is a perspective view of the housing for the signalling flag.
Figure 6 is a perspective view of the signalling flag and Figure 7 is a perspective view of the back plate for the housing.
Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates a substantially flat rectangular housing having an open back and formed with outwardly projecting flanges 6 at its side edges. A back or rear plate 1 is formed with inturned flanges 8 at its side edges providing channel guides for slidably receiving the flanges 6 of the housing, and the back plate I and flanges '6 are formed with alined openings 9 and Ill respectively for receiving screws or other fastening devices for attaching the housing to a suitable supporting structure.
Slidably mounted in the housing is a flag I I having forwardly projecting flanges l2 at its vertical side edges adapted to travel against the sides of the housing 5 which thus serve as a track for the vertical sliding movement of the flag. A transverse slot I 3 is formed in the top of the housing in front of the back plate 1 and in which the upper end of the flag is slidably mounted.
A coil spring M connects the lower flange l5 of the flag to the top of the housing to exert its influence on the flag to project the flag upwardly through the slot l 3,
A key operated lock [6 mounted on the housing on the front thereof includes a sliding bolt l1 adapted to frictionally engage one of the side flanges l2 to frictionally retain the flag in its retracted position, the bolt being retracted by a suitable key (not shown) The upper edge of the flag is formed with laterally projecting apertured lugs [9 for receiving a wire 20 which is also inserted through an apertured tongue 2| struck from the flanges 6, and through the handle 22 or other part of a conventional fire extinguisher 23, the ends of the wire being connected by a soft metal seal 24.
In the operation of the device with the fire extinguisher secured by the wire 28 and which also secures the flag II in its retracted position as shown in Figure 1 of the drawings it will be apparent that the flre extinguisher cannot be removed without breaking the seal 24 or the wire 2|]. Accordingly, as soon as the seal 24 or wire 20 is broken the flag II is released and the spring 14 will project the flag upwardly to expose the signal or legend 25 whereby to indicate that the fire extinguisher has been used or tampered with.
The upward movement of the flag ll raises the same above the bolt I! of the lock, the lock passing through a cut-out 26 in the bottom flange l5 of the flag and the bolt being of a spring projected type then abuts the side of the housing in the path of the lower edge of the flange I2 of the flag whereby to prevent return of the flag to its retracted position until the necessary key is applied to the lock to retract the bolt.
It is believed that the details of construction and manner of use of the device will be readily understood from the foregoing without further detailed explanation.
Having thus described the invention, what I claim is:
1. A signaling device of the class described and comprising a housing, a spring projected flag mounted in the housing and containing indicia concealed in the housing when the flag is in its retracted position, the frangible means connecting the flag and an object to the housing and retaining the flag in its retracted position, said flag being released upon a breaking of the connecting means by a removal of th object.
2. A signaling device of the class described and 3 comprising a housing, a spring projected flag mounted in th housing and containing indicia concealed in the housing when the flag is in its retracted position, frangible means connecting the flag and an object to the housing and retaining the flag in its retracted position, said flag being released upon a breaking of the connecting means by a removal of the object, and means controlled by projection of the flag to lock thefiag in its projected position.
3. A signaling device of the class described and comprising a housing, a spring projected flag mounted in the housing and containing indicia concealed in the housing when the flag is in its retracted position, frangible means connecting the flag and an object to the housing and retaining the flag in its retracted position, said flag being released upon a breaking of the connecting means by a removal of the object, and a lock in by projection of said flag to lock the same against 10v retraction from projected position.
