BOTTLE-HOLDING GAGE FOR FIRE-EXTINGUISI-IERS.

Specification of Letters Patent.

' Patented July 14, 1908'.

To all whom it may concern:

Be it known thatI, JOHN F. KELLEHER, a citizen of the United States, residing at St. Louis, in the city of St. Louis and State of. Missouri, have invented certain new and useful Improvements in Bottle-Holding Cages for Fire-EXtinguishers, of which the following is a specification.

My invention relates to improvements in fire extinguishers, especially to the cage provided therein for supporting the bottle or other vessel filled with the acid, and consistsof an improvement therein which is simple in construction, is comparatively inexpensive, and easily positioned in and removed from the receiver containing the usual chemical solution.

In the accompanying drawings which are hereto attached and hereby made a part of the specification, Figure 1 is a side view partly in section of a receiver having my improved cage in place therein Fig. 2 is a detail showing the device for maintaining the bottle in proper position; Fig. 3 is an upper plan view 0 the cage, illustrating the position of the clasp member when in its normal bottleengaging position Fig. 4 is a View of the bottle holding cage with parts broken away to show clearly the extension upon the finger adapted to contact with the upper portion of the bottle.

Referring to the drawings in which the same numerals indicate the same parts throughout, 1 is a receiver containing the usual chemical solution, provided at its lower end with the handle 2 by which the receiver may be grasped when it 1s desired to manipulate the same to break the acid bottle. At its upper portion the receiver is provided with the flanged portion 3which is externally threaded as shown at 4, for the reception of the annular cap 5 which is internally threaded as shown at 6 whereby the same is screwed into position upon the flange 3. The receiver adjacent its upper end is provided with the lateral annular flange 7 projecting inwardly; 8 is a cage for receiving the acidbottle 9, and com rises the vertical side stripsv 10 and 11, an at intervals as desired, the rings 12, 13 and 14 are secured uponthe side strips. The lowermost ring 12 is provided with an annular flange extendin inwardly, upon which rests the bottom 0 the bottle 9, when the same is in position. The

upper ring 14 extends on the outside of the side strips, forming an annular external flange 15 thereon, which,.when the cage is dropped into the osition in the receiver shown in Fig. 1, wil engage with the annular internal flange 7 and will rest thereon, whereby the cage is suspended in the upper ortion of the receiver. On its u per face t e ring 14 is provided with u war ly extending lugs 16, the outer face 0 said lugs being coincident with the outer portion of said flange 15, so that when the cage is positioned in the receiver the lugs 16 contact with the inner face of the flanged portion 3 of the receiver. If, when the cage is in place, the receiver be detached or swung from side to side, the lugs will hold the cage ri idly in its position upon the long diameter 0% the receiver, and thereby revent a movement of the bottle which mig t cause it to break prematurely.

To provide for the further security of the acid bottle, the cage is provided near its upper end with the finger 17, which is pivoted at 18 in a recess in one of the lugs 16. The finger at its pivoted end is so constructed that it will permit a swinging movement upwardly beyond the circumference of the ring 14, but can be swung inwardly and approximately only to the middle of the cage, being stopped by the contact of the curved portion 19 with the face 20-ofthe depression in the lug 16. When the finger occupies its inner position, the rear portion 20 thereof adjacent the pivot is flush with the external face of the lug 16 upon which it is mounted; therefore the finger offers no obstruction to the ositioning of the cage in the u per portion 0 the receiver. At its free end tiie finger is preferably bifurcated, the arms 21, 22 being adapted to embrace the neck of the bottle, and hold the same against lateral movement; the finger also may be provided with the downward extension 23 which will contact with the upper portion of the body of the bottle, thereby tending to position the bottle more securely. In order to position the bottle in the cage, the finger is swung outwardly, the bottle is then dropped into the cage, the bottom thereof resting upon the internal flange upon the ring 12, and the finger will then be dropped to its inner position, in which it will embrace the neck of the bottle; the cage containing the bottle is now dropped into position Within the receiver, the external face of the pivoted end of the finger being in contact with the fiange ortion 3 of the receiver, which contact w maintain the finger in its inner position. The annular cap 5 is now screwed into position, the under face of which will engage against the upper ends of the lug 16 on the cage, thereby preventing the ca e from falling outwardly if the receiver shou' d be inverted. The bottle is prevented from falling outwardly if the cage should be in verted by the contact between the body thereof and the finger, the inner arms of the latter also preventing the bottle from moving laterally. The lateral movement of the bottle is also prevented by the ring 13. By this arrangement of parts, therefore, any movement of the acid bottle, when the parts are positioned, is entirely prevented.

To break the bottle when desired, I pro vide the plunger 24 which passes through an opening 25 in the cap 5, the plunger having at its outer end the head 26, between which head and the cap is provided the spring 27. If the receiver be now inverted and dropped upon the ground or floor, the plunger will be driven inwardly and will penetrate the bottle seal of the bottle, breaking the same, whereupon the acid will flow into the receiver and combine with the, chemical mixture therein, and the same will be forced out wardly through the opening 28 into the tube 29, whence it may be directed to any desired point.

From the foregoing description it is seen that I provide a bottle-holding cage for fire extinguishers which is extremely sim le in its construction, is rendered operab e by merely positioning the same, has no parts which are readily put out of order, and may be applied to most fire extinguishers now in use.

I do not limit myself 'to any specific. number of rings or vertical side strips, nor to any number of lugs at the upper end of the cage, nor is it necessary'that a continuous flange be provided either upon the cage or upon the receiver, inasmuch as lugs placed at intervals would answer the same purpose.

claim as new and desire to secure by Letters Patent is 1. In a fire extinguisher, a receiver, a removable cage adapted for the reception of a bottle and having an annular ring adjacent its upper end, a pivotally mounted member depending from said ring and adapted to engage said bottle to position the same firmly in said cage, and an upwardly extending proleption on said member adapted to engage against said receiver when said cage is positioned therein, whereby said member is maintained in engagement with said bottle.

2. In a fire extinguisher, a cage adapted for the reception of a bottle and having an annular ring adjacent its upper end, a swinging clasp member constructed to embrace said bottle adjacent its neck depending from said ring and adapted to be swung outwardly when the bottle is being positioned in or removed from said cage, and to be swung inwardly to engage said bottle when the latter has been positioned in said cage, and means for maintaining said swinging member in engagement with said bottle.

3. In a fire extinguisher, a receiver having a neck portion, a removable cage adapted for the reception of a bottle and adapted to be suspended in said receiver from said neck portion, an annular ring formed on said cage adjacent its upper end, upwardly extending projections on said ring adapted to engage with said neck portion to prevent the swing,- ing of said cage, a pivotally mounted member depending from said ring, and adapted to engage with said bottle when the latter is positioned in said cage in said receiver, said member having an upwardlyextending projection adapted to engage with said neck portion to prevent the disengagement of said member from said bottle when the latter occupies its normal position in said cage in said receiver.

In testimony whereof I aflix my signature in the presence of two witnesses.
