New Adjustable Fire Nozzle Support
A new invention is an adjustable fire nozzle support, which may be quickly and securely attached to a window sill, frame, or other convenient point, and provided with adjustable means by which the nozzle is clamped or secured and by which the direction of the stream may be varied as desired. Another advantage claimed is that a number of nozzles may be simultaneously supported and adjusted for directing several streams upon the fire, so that they may be centered upon one point or directed in widely divergent directions, as the character of the fire may dictate. Besides this, the adjusting is so arranged that during the throwing of the stream the support will sustain all of the recoil of the hose, thereby relieving the firemen of undue strain or danger on .this account.
Referring to the drawings: Fig 1 is a side elevation of the improved fire nozzle support showing it in connection with a window sill (in section); Fig. 2 is a front elevation; Fig. 3 is a top view of the upper nozzle clamp removed and showing the device attached to the vertical frame of a door or post; Fig. 4 is a perspective view of the body casting to which the various parts of the device are secured; Fig. 5 is a perspective view of the several brace bars removed from the apparatus but retaining their relative positions, and Fig. 6 is a side view of one of the adjustable yokes for the nozzle clamps.
2 is the body frame, the shape of which will be best understood by reference to Fig. 4. As shown, the U-shaped nozzle clamp 27 is pivoted on a transverse axis, as indicated at 28, so that the nozzle 50 may be oscillated in a vertical plane about the transverse axis for directing the stream at different elevations or depressions. The adjustment of the nozzle clamp 27 may be fixed, if desired, by means of the link 31-a hinged at one end to the yoke 26 and adjustably clamped at 32-a to the nozzle clamp, as fully shown in Fig. 1.
The body part 2 is also provided with horizontal holes 24 and 25, respectively, at opposite sides of the vertical hole 23, the holes respectively supporting two additional clamping means, one of which comprises a yoke 31 having the journal pin 32 journaled in the hole 24, the yoke provided with a nozzle clamp 33 hiuged to the yoke on a vertical axis indicated at 34, and the other of which comprises the yoke 35 having the pin 36 journaled in the hole 25 of the body and the yoke provided with a nozzle clamp 37 pivoted to the yoke on a vertical axis at 38, the yokes 31 and 35 being respectively arranged at opposite sides of the body portion 2, and at a lower level than the first mentioned yoke 26.
The body part 2 is supported upon two hinged frames, 3 and 8, respectively joined to opposite ends of the body by transverse bolts 5 and 10. To insure more stability in a transverse direction, the bars 4 of the frame 3 are bent to spread at the bottom so that the transverse plate 6 may be of considerable length and provide for a series of the prongs 7, whereas the bars 9 do not spread, inasmuch as there is only a single prong 15 controlled by the adjusting screw 12.
As seen from Figs. 1 and 5, the bracing bar structure comprises two horizontal bars 16, respectively connected at their opposite ends with the frames 3 and 8 by transverse bolts 19 and 18 having spacing tubes 21 to keep the bars apart, four oblique bars 17, two of which are joined to the bolt 18 and two to the bolt 19, the bars having their other ends crossing and bolted rigidly at 20 to the body frame 2; and also two bars 16-a, each connected at one end to the bolt 19, and its other end to a transverse bolt 16-b which
extends between the opposite members 9 —9 of the frame
8 a considerable distance below the bolt 18. The bars 16-a sustain the recoil or kick-back during the passage of water under high pressure through the nozzle (Fig. 1).
Fig. 1 indicates the adaptability of the improved nozzle supporting means attached to the window sill 43 in position to play the stream upon a building across the street or upon the same building at a distant place. In other cases, the device would be clamped to the window sill in the opposite direction so as to play the stream into the building to which the clamp is attached.
The adjustable fire nozzle support is the invention of Jacob B. Blaw, of Atlantic City, N. j., and the patent number is 1,451,006.
