PATENT OFFICE 2,067,044 PORTABLE STANDPIPE Application March 5, 1929, Serial No. 344,338

5 Claims.

This invention relates to a turret standpipe; and has for its object to provide a portable standpipe which will be firmly supported when resting upon a floor or the ground while in operation without being manually held or attended.

A further object of the invention is the provision of a portable turret standpipe with a pair of supporting arms which may be folded to lie along the standpipe when not in use but which may be swung to extend at right angles to the st-andpipe when in operation to firmly support the same and prevent the standpipe from tipping.

With these and other objects in view, the n- Vention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:`

Fig. 1 is a top plan view of the standpipe with the arms in folded position.

Fig. 2 is a side elevation thereof.

Fig. 3 is a top plan view of the standpipe with portions broken away showing the arms in extended position.

Fig. 4 is an end view of a portion of the standpipe shown in Fig. 3 and showing the arms in extended position.

Fig. 5 is a perspective View of one of the arms.

Fig. 6 is a sectional view showing the pin for holding the arms in different adjusted positions.

In the use of turret standpipes for fire fighting, it has been custom-ary to xedly support the standpipe on a fire fighting truck to be manipulated therefrom as if taken from the truck, several men would be required to hold the standpipe in a position fo-r advantageous operation, and in order to provide a standpipe which will rest on a generally fiat surface without being manually held, I have provided a pair of arms which may be extended at right angles to the body of the device having spurs at their extremities to cooperate with feet at the opposite end of the device to provide a substantially three-point suspension for supportin-g the standpipe on a generally flat altho somewhat rough or uneven surface such as encountered in re fighting; and the following is a detailed description of the present embodiment of this invention illustrating the preferred means by which these advantageous results may be accomplished:

With reference to the drawings, I0 designates the body of the turret st-'andpipe having inlet openings II, I2, and I3 at one end thereof and is turned upwardly by an elbow member I4 at its discharge end to which upturned portion the head I6 is swivelly mounted. This head is of the customary Y-construction having parts I'I and I8 with inturned ends between which the member I9 of the nozzle 26 is swingingly mounted, while a suitable shut off valve 2| having a manu-ally operated handle 22 is located in the member I9 for controlling the flow of water thru the nozzle.

A front plate 23 extends across the body of the standpipe and at each side of this plate there is pivotally mounted an arm 24 having a bifurcated end with

portions

25 and 26 having openings 21 and 28 therein to receive a pivot pin 29 having a spur 3|] at one end thereof to hingedly mount the arm 24 so that it may be moved to the folded position illustrated in Fig. 1, substantiallyV parallel with the body portion of the standpipe when the device is not in use or may be swung to the extended or spread position, illustrated in Fig. 3, at right angles to the body of the device when in operative position. Spurs 3| are provided on the free ends of the arms and when the arms are extended they are widely spread and cooperate with the closely spaced spurs 32 extending from a point adjacent the inlet end of the body to provide a substantially three-point support for the standpipe when the arms are in this spread position.

Spurs 3| and 32 have their extremities in substantially the same plane to support the body I0 parallel to the surface engaged by these spurs, while auxiliary spurs 36 are provided on the ends of pivot pins 29, the tips of which are inset inwardly from the plane of the spurs 3| and 32 so that they will not come into engagement with the supporting surface until the spurs 3| have parti-ally imbedded themselves into a soft support such as soft ground or the like upon which the device may happen to be positioned in which softened surface it is desired to have additional holding means for the standpipe, in order that it may be more rmly supported to resist the tendency of pressure of the Water passing thru a pipe to move it.

The arms 24 are held in extended position by a pin 34 extending into an opening 35 in the arcshaped bifurcated part 26 and held in folded position when the pin 34 engages the opening 36 in this same part. This pin is movably mounted in the face plate 23 and forced into position to extend into the said openings by means of a spring 31 engaging a shoulder 38 of the pin 34 at one end and an abutment 39 on the plate at the other end. The pin is lifted from engaging position by a handle 4I) after which the arm 24 may be swung until the next opening comes into registry with the pin whereupon the spring forces the pin into this opening to prevent further movement of the arm until again lifted by the handle 40. However, when desired to move the arm 24 from folded position to a position at right angles to the body, the handle must be held in order that the pin will drop into one of the openings 35 and 36 while any desired range of .swing of the arm 24 may be had by providing` a suiciently long arc portion 26 with an opening to receive the locking pin.

A turret standpipe, as here illustrated, with the elbow member I4 for directing the stream of water upward and the nozzle member in the position illustrated in Fig. 2, or substantially parallel with the body Ill, so compensates or balances the force of the water that there is practically no pressure upon the outlet end of the body tending to force the legs or spurs 3| and 30 onto the support so that when the nozzle is in this position the front or outlet end of the body may be moved by a single person at will, and under certain conditions in operation, I have found that the pressure of the water going thru the pipe with this upturned elbow, is such that the feet and spurs 30 and 3l do not rest upon the ground but are lifted from the supporting surf-ace as high as an inch or two showing that there is no weight whatever on the forward end when the nozzle is in the position illustrated in Fig. 2. However, as the nozzle is raised to an angular position such that the line of stream directed therefrom if extended rearwardly from the nozzle would fall between the

spurs

32 and 30 then the pressure begins to act slightly upon the forward spurs 33 and when the nozzle is perpendicular the maximum pressure is on the spurs 3D and 3| which bite into the ground with a force far less than that experienced in the standpipe of the construction illustrated in my copending Patent No. 1,738,421, led December 15, 1927.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being dened and limited only by the terms of the Vappended claims.

I claim:

1. A portable turret standpipe for re hose, comprising a tubular body member having inlet openings at one end and an outlet opening at its opposite end, and a pair of arms pivotally mounted on opposite sides of the body member to swing from a folded position substantially parallel with the pipe to an extended position at substantially right angles to the pipe, a pin reciprocatably mounted on said body member for each arm, each arm having a portion with a plurality of openings therein located to pass beneath said pin when swung on its pivotal mounting, and means for shifting said pin to engage one of said openings and lock the arms in the desired position.

2. A portable turret standpipe for fire hose, comprising a tubular body member having inlet openings at one end and an outlet opening at its opposite end, and a pair of arms pivotally mounted on opposite sides of the body member to swing from a folded position substantially parallel with the pipe to an extended position at substantially right angles to the pipe, a pin reciprocatably mounted on said body member for each arm, each arm having a portion with a plurality of openings therein located to pass beneath said pin when swung on its pivotal mounting, and a spring for shifting and holding said pin in an opening when swung into registry with said pin.
