This invention resides in the provision of a simply constructed, collapsible, portable, small, compact, light, strong, durable and efficacious means for holding a fire hose in such manner that one operator can safely and easily play the hose in both horizontal and vertical planes with little or no efiort.

A single fire hose through which a high pressure stream is passed usually requires from three to five men to hold and properly manipulate the nozzle, but with the present invention one operator may safely and easily manipulate the nozzle in a most effective manner, thereby providng for a saving of time and labor, and eliminating the injury hazard in the fighting of fires.

One of the advantages of the invention is the provision of a portable, light and col-- lapsible holder which may be quickly and easily set up for operation and when not in use may be collapsed into small compass and readily and conveniently stored or carried.

Another object is to provide a means whereby the nozzle may be easily, quickly and safe- 5 ly attached to and removed from the holder, which means permits the nozzleto be turned freely and easily in vertical and horizontal planes to properly direct the stream of water in fighting a fire.

Another object of the invention is to provide a fire hose holder of the character described which has a novel base that permits of simple construction, the employment of but few parts, and provides for secure, stable supporting of an upright standard on which is carried the means for clamping the fire hose to the holder.

A further object of the inventon is to provide a fire hose holder of the character de- 0 scribed in which by means of a simple adjustment, the play pipe may be stationarily held in various positions without requiring the attendance of the operator.

With the above mentioned and other ob- .35 jects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings, and set forth in the claims hereto appended, it being understood so that various changes in the form, proportion,

' and nozzle clamped on the holder. 6

size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Referring to the drawings Fig. 1 represents a vertical sectional View of the holder of my invention as when set up ready for use, the hose being omitted.

Fig. 2 represents a fragmentary horizontal sectional view taken through the collapsible base.

Fig. 3 represents an enlarged vertical sectional View taken at right angles to the view shown in Fig. 1, and showing the hose Fig. 4t represents a fragmentary top plan view of the means for clamping the hose.

Fig. 5 represents aside elevation of the holder as when collapsed.

The embodiment of the invention shown in the accompanying drawings comprises generally an especially constructed collapsible base 1, supporting a take-down sectional upright standard 2, which latter carries at its upper end an especially constructed 75 pivoted means 3 for clamping the coupling of the hose and nozzle upon the holder, which means is constructed so that it may be held stationary in any one of several positions of adjustment of the nozzle in a vertical plane. This means together with the standard, provides generally speaking, a safe swivel mounting for the fire hose and nozzle at the juncture thereof and provides for awide range of movement of the nozzle in vertical and horizontal planes. These elements of my holder are so constructed and relatively arranged that when a flexiblefire hose having been coupled to the discharge end thereof in the usual manner, a play pipe or nozzle is clamped on the holder at the coupling of the nozzle and hose, a single operator. may safely and with little or no effort direct th stream from the nozzle as required,-with greater ease and facility than can three or more operators without the holder of this invention. V

The especially constructed base 1 comprises a plurality of arms i which are carried by and at the lower end of the sectional standard 2-,

all)

and project radially outward therefrom, there being a plurality of downwardly and outwardly projecting feet 5 on the outer ends of these arms, which feet are pointed and adapted to engage the ground or other surface on which the holder is mounted in such manner as to firmly anchor the holder against slipping thereon.

The standard 2 comprises an inner tubular section 6 telescoped and adapted to turn freely within an outer tubular section 7, which latter carries a plurality of pairs of spaced apertured ears 8 between which the inner terminals of the arms 4 are hinged by means of pins 9. Extending upwardly from the inner ends of the arms at are projections 10 which extend along the outer side of the tubular section 7 in engagement therewith and limit the movement of the arms so that they extend substantially horizontally from the lower end of the standard. A flanged collar 11 surrounds and is slidably mounted upon the standard 2 in such manner that the upward projections 10 may be engaged between the standard and flange 12 of the collar, thereby holding the arms 4 in properly extended position to support the standard. It will be noted that the co-acting faces of the flange 12-and projections 10 are inclined so as to fitsnugly and produce a w-edging action and thereby prevent accidental displacement of said parts. The standard 2 is provided in its sectionso and 7 with registering openings 13 disposed in such a position that when a pin 14 attached by a flexible element 15 to the collar 11 is inserted through said openings, thecollar will be held against moving upward out of position when the arms are collapsed. The base may be collapsed by lifting the collar 11 clear of the upper projections 10-and thereby'permitting the arms 4 to swing into substantially upright position hanging downward from the lower end of the standard. In this position as shown in Fig. '5, the projections 10 extend outwardly laterally from the sides of the standard and by lowering the collar so that the flange 12 thereof engages the upper sid s of these projections and inserting the pin 14 in the openings 13, the collar will'again be held in such position as to prevent the arms from swinging on their pivots, thereby holding the arms in collapsed position.

When the arms are in this position, the entire holder is reduced to a compact form, so

that it may be conveniently stored and car ried. I

The arms 4 are provided with sockets 16 in.

which rods '17 are held by means of fasteningelements 18, the rods'extending laterally outer tubular section 7 and limits the downward movement of the inner section to the extent that its lower end is disposed substantially flush with the outer section. The inner section is enlarged as at 21 at its upper end and is bifur ated as at 22, there being provided opposed plate-like portions 23 between which the clamping means 3 is mounted so that it may be freely turned in a vertical plane.

The clamp 3 is in the form of a sectional circular band comprising two sections24 'a'nd 25 of which the section 24 is provided at its terminals with plate-like portions 26 corresponding to the portions 23 and engaged therewith. These portions 23 and 26 areproi. vided with registering openings '27 and 28 of which the ones 28-are screw threaded. Pivot bolts 29 are inserted throughthe openings 27 and 28 and are provided with'screw threads on their free ends which threads cooperate with threads in the openings 28. On'tig'htening these pivot bolts, the clamping means 3may be held in any one of its adjusted positions thereby providing for holding the playpipe in the desired position when thus adjusted, although ordinarily thesebol'ts provide for securing the clamp so that it may be freely turned in a vertical plane. The outer section'25 is hinged as at 30 at one end to one end of the section 24. At its otherxend this section 25 is provided with on outwardly opening slot 32 adapted to receive a threaded bolt 33, hinged atone end as at 34 to the corresponding end of the section 2 1. A nut 35 is turned on the outer end of this bolt 33 and is adapted to bear against the slotted terminal of the section 25 to effeet the clamping action. This bolt may be swung freelyinto and out of the slot 32 when the nut 35 is loosened. The clamp is especially constructed to receive and hold a'standard type coupling 36 which is used to connect the nozzle or play pipe .37 with the flexible hose 38,*it being necessary to provide in the lower section 2-lan opening 39 of sufficient size to receive different sized lugs 40 such as are provided .on said coupling. The upper section 25 is provided with an elongated slot 41' adapted to receive a similar lug 42 carried bysaid coupling 36 on the side thereof opposite the lug 40. The sections of the clamp are of such a width 'a-s to securely and firmly clamp the coupling without in any way interfering with the operation of screwstability of the holder.

ing the nozzle into or unscrewing it from the coupling.

Y Vith the holder arranged as shown in Fig. 1, to attach the hose,the clamp is opened and the coupling 36 is placed in the lower section 24 after which the upper section 25 is brought down upon the upper side of the coupling and clamped by means of the bolt 38 and nut 35. The operator then by grasping the play pipe or nozzle and in some instances bending the fiexible hose adjacent the nozzle with the knee, may freely turn the nozzle in a horizontal plane, due to the rotation of the inner section 6 of the standard within the outer section 7. The pivotal mounting of the clamp provides for free vertical movement of the nozzle. With this arrangement, a single operator may safely and with little or no effort direct a stream of-water a as desired in fighting a fire. The lines of force resulting from the re-action of the water discharging from the nozzle pass downward through the stand and are evenly distributed in such manner as to increase the When a shut off type of nozzle is employed, the stand will support the hose and nozzle in proper posi tion when the water is shut ofi at the nozzle- If desired, the operator may on tightening the pivot bolts 29, hold the clamp against pivotal movement in a vertical plane and thereby hold the nozzle in any one of several adjusted positions. When thus clamped. the operator need not hold the nozzle inasmuch as it will be stationarily and securely held in the desired position. If desired to prevent horizontal turning of the nozzle, the pin 14: may be inserted in the openings 13 as shown in Fig. 3, thus preventing rotation of the inner section 6 of the standard.
