4 Claims. (Cl. 248-75) The present invention relates to a mounting rack for fire hose nozzles, and more particularly to a rack for converting a ladder pipe nozzle into a deluge gun.

Prior to the present invention, it was necessary for a fire company to purchase, in addition to the standard ladder pipe nozzle which is adapted to be mounted on the uppermost rungs of an aerial ladder, a deluge gun, which is adapted to be mounted on the ground. In many instances, especially in small volunteer fire companies, the expense of a separate deluge gun is too great in relation to the amount of use to which such a gun would be put. Because of this, such fire companies must forego the advantages of a deluge gun, and when the need for such equipment arises, they must use a standard nozzle and station two or more firemen to hold the nozzle. This procedure is wasteful manpower, which is very limited in many fire companies.

With the foregoing in mind, the present invention provides a mounting rack for a ladder pipe nozzle which enables the ladder pipe nozzle to be used as a groundmounted deluge gun.

More specifically the invention contemplates a rack upon which a ladder pipe nozzle may be releasably clamped and which will firmly anchor the nozzle against displacement on the ground so that it may be used as a deluge gun.

The invention provides a rack of simplified construction which is fully eifective in operation and use and which is Within the financial means of the average small volunteer fire company.

All of the objects of the present invention and the various features and details of the construction and operation thereof are more fully set forth hereinafter with reference to the accompanying drawing in which:

Fig. 1 is a perspective view of a rack made in accordance with the present invention showing a ladder pipe nozzle mounted thereon;

Fig. 2 is an enlarged perspective view of the rack shown in Fig. 1, but in collapsed position for storage;

Fig. 3 is a fragmentary perspective view of the rack in extended position showing certain structural details thereof;

Fig. 4 is an enlarged sectional view taken on the line 44 of Fig. 2;

Fig. 5 is an enlarged sectional view taken on the line 55 of Fig. 2; and

Fig. 6 is a sectional view taken on line 66 of Fig. 5.

Referring now to Fig. 1 of the drawing, the invention provides a rack 10 for mounting the standard ladder pipe nozzle 11. The pipe nozzle 11 includes clamping means 12 which are adjusted to securely clamp the nozzle 11 on the uppermost rungs of an aerial ladder. The rack it) comprises a pair of spaced parallel side members 14, 14 interconnected by cross pieces 15, 15. Each side member 14 consists of a channel iron having upper and lower flanges 16 and 17 respectively and a web 18. It is noted that the upper and lower flanges 16 and 17 converge slightly from the forward end of the rack rearwardly.

atent At the forward end of each side member the flanges 16 and 17 are interconnected by an end piece 19. The cross pieces 15, 15 are hollow tubular members 21 having a resilient cover 22 of rubber or other suitable material. The tubular member 21 is secured to the web 18, for example by welding as indicated at 23.

In accordance with the present invention stabilizing arms are pivoted to the side members 14, 14 at their forward end. In the illustrated embodiment of the in vention, the stabilizing arms 25, 25 comprise channel members having upper and lower flanges 26 and 27 and a web 28. Each arm is hinged to its associated side member 14 as indicated at 29, and the upper and lower flanges 26 and 27 converge toward the free extremity of the arm 25, as shown. An end cover 31 bridges the flanges 26 and 27 at the free extremity of the arm and provides a finger grip for operating the arm.

As shown in Fig. 4, the hinge 29 comprises upper and lower bushings 33 and 34 respectively which are snugly received in the apertures in the upper and lower flanges respectively of the side member 14 and the arm 25. A hinge pin 35 is engaged in the bushings 33 and 34 to retain them in place. The present construction of the hinge affords minimum play between the arm and the side member and affords ready pivotal movement thereof between the open position shown in Fig. l and the closed position shown in Fig. 2.

In accordance with the invention, to provide a firm anchoring of the rack on the ground, pins are mounted at the opposite ends of each side member 14 and at the free extremity of each stabilizing arm 25, as indicated at 36, 37 and 38. The pins 36 and 37 are mounted in the lower flange 17 of the side member 14 and depend downwardly so as to engage the surface on which the rack is mounted. The pin 33 likewise depends downwardly from the lower web 27 of'the stabilizing arm 25.

In the operation of the rack, when the nozzle 11 is being used as a deluge gun, the reaction force of the water leaving the nozzle causes the pins to imbed themselves firmly in the surface on which the rack 10 is mounted. The stabilizing arms insure firm engagement of the rack with the surface when the nozzle is rocked laterally, and the spaced reiation of the pins 36 and 37 insure firm engagement when the nozzle is rocked vertically. To enable the stabilizing arms 25, 25 to be received between the flanges of the side pieces 14-, 14 the lower flange 17 of each side piece is formed with a cut out 39 to receive the pin 38 when the stabilizing arm 25 is closed against the side piece 14.

Means is provided to releasably lock the stabilizing arms in their closed positions when the rack is not in use. To this end a latch element 46 is mounted on the web 18 of each side member 14. The latch element 40 projects outwardly and is operable to project through an aperture 41 in the web 28 of each stabilizing arm 25 into engagement with a spring-biased keeper 42 mounted on the upper flange 26 of the stabilizing arm 25. Thus when the stabilizing arm 25 is closed into position intermediate the flanges 16 and 17 of the side member 14, the keeper 42 engages over the latch element 40 to releasably retain the arm in its closed position. latch is readily disengaged by swinging the stabilizing arm 25 outwardly, for example by the operator engaging his finger behind the cover portion 31 of the arm. The opening movement of the stabilizing arm is limited by engagement of the upper and lower flanges 26 and 27 thereof against the end piece 19 of the side member 14. It is noted that the arm moves to an angle slightly greater than to provide a firm and stable support for the nozzle 11 mounted on the rack 10.

While a particular embodiment of the present invention has been herein illustrated and described, it is not The e V r 2,929,597 r intended to limit the invention to such disclosure but changes and modifications may be made therein and thereto within the scope of the following claims.
