. This invention relates to lawn and garden sprinklers-and more particularly such sprinklers of the fiat spray type. 7

The object of the invention is-to provide a flat spray spinkler from which a spray of uniform length will issue from all points of the sprinkler nozzle. 1

Other objects and advantages of the inventionwillbeunderstoodby reference to the following specification and accompanying drawing,vinwhicha flat spray nozzle embodying a selected form of the invention is illustrated. In the drawing:- 4

Fig. 1 is a perspective; V v Fig. 2 is a section on a plane extending through the length of the nozzle, and

Fig. 3 is a section on the line 3 3of Fig. 2. .Beferring now to the drawing, my im proved nozzle includes a hollow body member 5 which includes an intake end portion 6 and a flared, fan-shaped front end or mouth portion- 7. The intake end, portion is provided with an enlargement 8 which is interiorly threaded, as indicated at 9, for receiving a hose connection 10 of suitable form. A rubber or other suitable washer 11 may be seated on the shoulder 12 for co-operating with the hose coupling 10 to provide a leak-proof joint between the hose coupling and the sprinkler body. v l The body 5 is preferably formed of cast metal, such as brass or other suitable nonrusting material, and a sheet metal sprayhead 13 is mounted on the front end 7 of the body. As clearly shown in the drawing, the spray-head 13 is provided with a peripheral flange 14c which fits around the marginal front edge portion of the body and facilitates permanent connection of the spray-head and body by means of soldering or otherwise. The sheet metal spray-head 13 is provided with a plurality of apertures 15 which permits streams of water to issue from the hol low body 5.

It has been found that, in the absence of some provision to prevent it, the streams which issue from the apertures 15 are longer near the opposite ends of the sprinkler than those which issue from the centrally located serial No. 573,616.

openings. Such. v irregularity of the streams is objectionable, and to prevent it and: to cause the streams to be of uniform length. throughout the length of the sprayhead, I have provided a pair of metallugs 16 and 17 respectively, which are castin tegral with the body'5. f v z T The lugs 16 and 17 are so shaped and arranged that they provide, inside faces 18 whi ch are substantially parallel and arranged approximately in alignment with portions of thewall 6. of .the i'nlet opening -As" shown in Fig. 2,.the lugs 16 and 17. are generally of triangular, formation, and in addition to the substantially parallel faces 18, they provide frontfaces 19, which-diverge outwardly and rearwa'rdly from the spray-head 13. Rear faces 20 are .also formed, these faces being approximately p arallel to oppositely disposed portions 21" of the spray-head,.as clearly shown'in Fig. 2. The opening in the nozzle between the faces 18 of thelugs is of substantially the same cross-sectional areaas the. area of the inlet opening and the'cross-sectional areas ofthe in the length Q'OR "r0 a. ew nanvmcrnnme spacesbetween therear faces20 of the lugs and the oppositely disposed inside face POT-1 tions 21 of the body member are considerably less than the areas of the inlet opening. I

I havefound by actual testing of. the

above-described: structure that it serves to equalize the pressure of the-water at all points and that the streams issuare of substanon the spray-head ing through the'apertures 15 tiallyuniform length throughout the length of the spray-head. As clearly shown in'the drawing, the spray-head is of elongated,

As is evident from an the lugs 16 and 17 serve, in effect, to divide the interior of the body narrow proportions; inspection of Fig. 2,

member into a'central passageway and oppo} site end or side passageways or chambers. a The above described structure is-susceptible of beingchanged in some respects without departing from thespirit of the in'vel'l tion, the scope of which shouldbe determined",

being construed as broadly as possible'consistent with thei state of- 'theartff r I by reference to the following claims, thesarne hollow body member to through said inlet opening,

I claim as my, invention:

1. A sprinkler comprising an elongated, narrow, multi-apertured spray-head and a hollow body member to which said head is secured, the body member being provided with an inlet opening spaced rearwardly from the head and located approximately centrally of the length of the head, andmeans ctingsubstantially uniform discharge 6f said head, comprising a pair *1 y triangular lugs respectively 1 pposite sides of the path of a water entering said'body through oas to provide a passageway of substantial ly the same size as said inlet opening directly from the latter to'the central portion of said: head and soas to provide reduced-size passageways from said-inlet opening to the opposite side portionsof said body and head. 2. sprinkler comprising an elongated, narrow, multi-apertu'red spray-head and a I I which said head is secured, the body member being provided with van inlet opening from the, head and located approximately centrally of the'length of thehead, and means for effecting substantially'uniform discharge of water through the openings throughout the length of said head and comprising a pair of lugsin said head at opposite sides of the path-of a stream of water entering said head I said lugs having inside faces substantially aligned with portions ofthe wall of said inlet openings, the front endsof said lugs beingdisposed closely adjacent saidfhead and the rear portions of saidlugs being spaced materially from the rear. Wall of the body member soas to provide passageways from said inlet opening to the opposite side portions of said: body, saidlugs being tapered laterally from saidfront' and rear ends in formation, so as to provide restricted passubstantiaslly triangular sages at the front and rear ends thereof.

\ 3. ;A sprinkler comprising an elongated,

5 narrow, multi-apertured spray-head and a cated; oni opposite v. stream of waterentering said head through 'said inlet opening, each of said lugs being I substantially in alignment with a portion of hollow body member. to which said head "is secured, the body member being provided" with an inlet opening spaced rearwardly of thehead, and means length of said head, comprising a pair ofvsubstantially, triangular lugs respectively losides of the path of a shaped-to provide an inside wall-disposed thewall of "the inlet opening, avfront wall diverging rearwardly and outwardly from said head,-and'a rear wall spaced from an ough the openings throughoutv said lugs being positioned spaced rearwardly and located approximately 4. A sprinkler comprising a substantially h tubular inlet portion having an inlet openingtherein, and a spray head communicating" therewith, said spray head extending forwardly and laterally on oppositesides. of said inletv portion to form an elongated narrow chamber, said chamber being bounded by side walls, amulti-apertured front wall, and opposite and similar rear walls diverging from said'inlet opening to the extremities of being so arsaidfront wall, said rear walls ranged that said'chamber tapers fromamaximum depth adjacent said inlet portion to a relatively shallowfminimum depth; adjacent the extremities of said chamber, and a pair of bafiles secured in said chamber to said side walls, said baflies having faces on opposite sides of acentral passageway defined'by them in prolongation of said inlet and terminatin contiguous t'o said front wall, each of said lugs also having a face spaced from and sub stantially parallel to one of said rearwall's so as to provide a restricted passageway therebetween, and a face joining said'last mentioned face and contiguous at its other end to said front wall adjacentsaid central pas sageway. o I Y 5.
