T. P. NEWMAN, ETAL HOSE SPRAY HEAD Filed Nov. s, 1959 spray head and connection therefor.

Patented Feb. 3, 1942 HOSE SPRAY HEAD Thomas P. Newman, Geneva, Eugene W. Marchand, Jr., Maywood, and Edward A. Fredrickson, Chicago, Ill., assignors to Crane o., Chicago, Ill., a corporation of Illinois v Application November 3, 1939, `Serial No. 302,646

' 10 claims.y (C1. 299-112) This invention relates in general to a hose It is applicable to various types of hose sprays, nozzles and connections and has particular utility in conjunction with kitchen sink or the like spray heads which are used for washing or rinsing the sink or articles contained therein.

We are aware that there have been previous types of spray heads in which the latter have been made integrally of metal; therefore, this invention contemplates the provision of a sprasT head whereby the handle or grip portion of the head which, though rigidly secured to the spray Y nozzle, is of a separate piece or construction and is preferably, although not necessarily, insulated against the rapid conduction of heat to the handle by air spaces and passageways allowing for the circulation of air between the nozzle and the handle.

Another object of the invention is to provide an improved hose connection which furnishes a leak-proof and secure attachment of the spray head to the hose with a minimum number of parts, the latter being easily and quickly assembled.

Other provisions contemplated by the present invention include a handle portion of the spray head which provides a convenient and comfortable grip for the fingers of a user, a shank portion which prevents rotating or turning of the head when the latter is at rest in its socket, and a spray face portion which is readily removable for cleaning and inspection purposes.

The manner in which the invention is carried into effect and its more detailed nature and advantages may best be understood from a consideration of the ensuing portion of this specilication, taken in conjunction with the accompanying drawing, in which a suitable form of apparatus is described principally by way of example.

In the drawing: Fig. 1 is an exterior plan view of our improved spray head.

Fig. A2 is a vertical sectional View of the spray `head showing the detailed construction thereof.

' Fig. 3 is a sectional View taken on the line 3--3 of Fig.V 2.

Fig. 4 is a sectional view taken on the line 4-4 of Fig. 2. K

Similar reference numerals refer to similar parts' throughout the figures.

-Referring to the drawing, and in particular to Figs. 1 and 2, the spray head embodying our `of thenozzle casing 2. In order to provide access yto thescrew I6 and for` inspection and cleaning invention comprises the grip or handle I which tube` or hose 8 is provided for the water supply to the spray head and is connected to the inlet end 9 thereof, the other end of the tube 8 is vconnected to a'suitable source of water supply (notshown) which, if desired, may be a backboard outlet on the sink faucet. The rubber tube 8 is preferably made sufficiently long to per- .mit a person at the sink to grasp and to lift the head -out of the socket 5, pull a portion of the tube through the socket and then to subsequently spray any portion of the sink or articles placedin the sink.

The nozzle casing 2 is formed with a substantially right angular bend in its middle portion and .an additional bend of about 45 near its voutlet end II. I .Thefinlet end .9 .of the casing 2 is provided .with a suitable means, such as .thebulged portion I2, for resisting sliding move- .ment of the hose. 8 telescoped thereon, and the -nutl3 is vscrewed onto the end of the hose to compress the .latter against the casing 2 above the bulge lI2 whereby the hose is securely connected .tothe nozzle in a leak-tight and slip- `proof manner. A preferably rubber sleeve 4 hav- -ing itsupper. end enclosed or shrouded by the handleA Irand its lower portiontapered is provided to enclose the hose and nozzle-connection -andto furnish an external gripping surface for they socket or bushing 5 to contact and to prevent the headfrom turning while the latter is positioned in the socket.

As more clearly shown in Figs; 3 and 4, the lower. portion of the handle I is widened and recessed so that` it forms a shroud or openbottomed coverfor the nozzle casing '2., The recess I3 in the lower portion of the handle conforms generally tothe shape of the nozzle casing but for. insulating purposes the recess is '.-preferably made suciently large to allow an air space I4 between the casing and the recess.

lAplurality of ribs I5 are provided in the recess Iliffor the relatively small contact areas between thecasing and the handle.

' Again referring'to Fig. 2, we prefer to conceal theattaching screw I6 within the outlet end Il purposesa cup-shaped spray face I'I is screw threadedly or otherwise removably `secured to the end II. of the casing 2.

The handle I, because of being preferably made of wood, rubber, plastic or some other composition, rhasrelatively poor heat conducting qualities. The upper orgrip portion of the handle comprises a thin Arib-like member having a rear- .wardly extending projection I8 beneath which either with an aperture or finger loop substan,

tially as indicated by the dash lines I9. Of

course, the particular shape of this handle with respect toits exterior conguration is not signicant, and may be changed to suit the type of installation.

While one form of the invention has been illustrated and described it is obvious that those skilled in the art may vary the details of construction as Well as the precise arrangement of parts without departing from thespirit of the invention, and therefore it'isjriotrth'e desireto be limited to the above disclosure except 'as may be required by the appended claims, considering the state of the prior art.

We claim:

1. A spray head comprising a casing having an inlet and an outlet, the said inlet having connection to a suitable source of water supply, a spray face member secured tothe said outlet, a handle i'or the said casing, the said handle having a lower overhanging portion and a nger grip portion, the said overhanging portion including a recess, ribs in the said recess and around a portion of the casing for the predetermined positioning of the said casing in spaced relation to the bottom of the said recess, whereby a clearance is provided between the said casing and the said handle, and means accessible through said outlet for assembly of said casing with saidhandle.
