NOZZLE FOR STREET \VASHING- AND SPRINKLING MACHINES.

Specification of Letters Patent.

Patented Nov. 21, 1 91 1.

Application filed January 25, 1911. Serial No. 604,624.

citizen of the United States, and a resident i of the city of St, Louis and State of nlissouri, have invented a new and useful 11nprovcment in Nozzhs for Street lVashing and Sprinkiin'g Machines, of which the following isa specification.

This invention relates to nozzles and more particularly to nozzles for street washing and sprinkling apparatus. The subjectmatter is divided out of an application for LettersPatent of the United States for im-.

provement in street. washing and sprinkling machines, Ser. No. 3%,516, filed by me on December 19,1906.

It has for its principal objects to improve generally upon nozzles for street washing and sprinkling machines, to provide for the discharge of the water with a considerable force from a relatively low, F'essure within the tank, to produce a concentrated and evenly distributed wide stream, and to secure ell'ective results from a minimum amount of water.

The invention consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawing which forms part of this specification, and Wherein like symbols refer to like parts wherever they occur: Figure 1 is. a side elevation of astreet washing and sprinkling machine equipped with a nozzle according to my invention; Fig. 2 isa front view of the. nozzle;

ig. u is a top plan view of the nozzle, -a portion being shown in section; Fig. 4 1s a section on the line 4.-4 of Fig. :2; Fig. 5 i;- a top plan view of the strainer, a portion being broken away to more clearly show the diaphragm; and Fig. 6 is a, section on the line fi-6 of lfig. 5.

As illustrated in the drawing, the machine comprises a truck-frame 1 which is mounted on frontandrear wheels 2 and 3, re-

A tank 4 is mounted on the frame 1. This tank is adapted to contain water under pressure when the machine is to be used for washing and flushing pur- An intake water-pipe 5 opens into he rear of the tank 4 near the. bottom. This Eipe- 5 is provided with an inwaxfly opeumg checkwalre (3 whose construction is ohions and hence not. illustrated in detail.

{in the outer end of the pipe 5 is attached a casing 7 containing a perforated (ha-- pliragm The casing has a screw-tln'eaded portion 9 udapted to receive the coupling member of suitable hose-pipe not shown) through which the tank may be titled with the water from a city main or other source of water supply.

The machine is provided with one or more delivery nozzles 10, as desired. Preferably, two nozzles are provided for the type of machine illustrated in the drawing. In this case, it. is desirable to locate, the nozzles forward of the rear wheels. The nozzles' 10 are preferably adjustably attached to a delivery-pipe 11 which extends laterally and downwardly from the hollom of the tank 4. The adjustment of the 11oz zles may be effected through the medium of a hall-and-socket or other suitable universal joint 12.

The nozzle lOis a hollow head whose bottom is closed but whose top portion has a,

threaded opening, therein to adapt it for connection to the lower member of the universal joint 12. The upper portion of this hollow head is inclined forwardly, downwardly and laterally, to an arcuale or cylindrical front'wall so as to makethe general livery part. Said circular wall is providtnl with a series of perforations 13 which are, preferably, slightly larger than the perforaions inthe strainer diaphragm S and whose diameters are greater than the spaces between them. Preferably, the perforations .13 are arranged. in two or m re parallel rows and the perforations of one row are staggered with relation to those of the other row or rows. In other words, the central points of the perforations of one row are in perpendicular alincment with points midway between the perforations of the other row. That is, the perforations of one row overlap those of the other row.

By providing the nozzle with a plurality of comparatively small perforations, arranged substantially as shown, the water is discharged from it with a considerable force from a relatively low pressure within the tank. The overlapping arrangement of parallel rows of perforations produces a concentrated and evenly distributed wide stream, and a minimum amount; of water can be discharged with good efl'ect.

The pert'orated strainer diaphragm Sprevents large gravel )l' other particles from passing into the walcr tank *1. By making each perforation in the delivery nozzles of larger area than the strainer perforations, any very small particles which might pass into the water tank can be readily discharged out through the nozzle perforations and clogging ol the nozzles is thereby prevented. liy providing a removable plug ll in a screw-threaded opening in the bottom of the nozzle, the interior thereof may be easily cleaned. i

A pressure tank If) is mounted inside of the water tank; and, for practical purposes,

it is preferable to have it extend from end to end thereof. This pressure tank may be charged through a pipe I from any suitable sourre of pressure supply. pipe IT ext nds from said pressure tank and communicates with the interior of the water tank at the top thereof, so that pressure is atall times exerted on the contained body ot water from ab ve. ln some L'tl 0$, where the water-supply is produced under heavy pressure, the pressure tank may be charged by allowing the air within the water tank to be displaced therefrom and forced into the pressure tank through the pipe l? by the incoming water while ;ll l water tank is being filled.

By simply maintainin the water in the water-tank under l| \'dlostttli4' pressure and adjusting the nozzle lo tllrt'lxitlgt'. slightly upward, the machine may be used For sprinkling purposes. as distinguished fro washing and flushing, for which latter purposes the water must be discharged downwardly at an inclination and under heavy pressure. in some cases, where a relatively wide street is to be sprinkled the water ls discharged from the nozzle under heavy pressure.

Obviously, my device admits of considerable modification without departing from my invention and, therefore, 1 do not wish A secondto be limited to the specific construction and arrangement shown.

What I claim is: v

1. In a street washing and sprinkling machine, a delivery nozzle comprising a hollow head having an areuate front; Wall, the horizontal dimension oi the chamber of said head widening and the vertical dimension of said chamber decreasing toward said front wall, said delivery nozzle having a plurality of comparatively small delivery apertures in its front wall, said apertures being ar 'angcd 'in parallel rows, and all but the entlinost apertures of one row being arranged to overlap two adjacent apertures in another row.

2. In a street washing and sprinkling machine, a dclhc-ry nozzle having a universal joint member for mounting it, said delivery nozzle having a plurality of comparatively small delivery apertures ar 'anged in parallcl tOWs. all the apertures of each row being of greater width than the spaces between said apertures.

3. in a street washing machine, a delivery nozzle. comprising a hollow head havingan arcaate front wall, the horizontal dimension of the chamber of said head widening, and the vertical dimension of said chamber dell't'tblllg' toward said front wall, said nozzle having a universal j int member for mounting it, said delivery nozzle having a. pinrality of eoniparatively small delivery apertures arranged in parallel rows in its front all, the apertures of each row being of greater width than the spaces between said aperti ires.
