SYRINGE HEAD.

Application nea February 2, 1924. seriai No. Gedisa scribed hereinaftenshown inthe .drawings andfiinally pointed out in the claims. Y

In the accompanying drawings, Y Y Fig. 1 is a longitudinal sectionaly y'View taken on line 1 1 of Fig. 2 othe'uppermostv or outermost end 'of Vmy improved i syringe head; y

Fig. 2 is an end view thereof; Fig. 3 is an end View of another g embodying my invention; Fig 4 is a longitudinal line v4-4 of Fig. 3. i l l Fig. 5 is a plan .View of the Jform shown in Figs. 3 and 4, showing the general direction of the jets;

Fig.v 6 is a perspective View of ahead emform " :ai loodyng my inventiomsliowing thesame j Vapplied to a particular orm of nozzle;

Fig. 7 isa section taken on line7-7 of Fig.6; and 2 y. Fig. 8 is an enlarged perspective vie-w of the outer end of the head shown in Figs. 6 and 7.

Similar characters of reference indicate corresponding parts throughoutfthe various.

views. Y

Referring to the drawings and more particularly to Fig. 6, there is shown a nozzle 10, which is provided-with longitudinal ribs 11, with valleys 12 therebetween. These ribs 11, and valleys V12, taperfrom one end o f the nozzle portion to the tip thereof.`v Within the valley portions there are arrangedopen- Y ings 13, 'either with one opening for each 'valley or two or lmore, as desired.- vThe `tapered end of this nozzle forms the head 50. thereot and inthis embodiment of theinsection taken on the end of the nozzle curved downwardly` ,vention is as also shown in Figs. 1 and 2, y, I

and inwardly. The peak 1V 14' of thenozzle in theembodiment sliownfin Figs. 1 andv 2' y is a circumferential, `rounded,portion. The. curved downward Vand inward depression Ywhich is indicatedyby. .15, forms, with the i' body portion of the nozzle, a chamber 16, and in this embodiment this chamber is single, and lextends circumferentially of the nozzle. Laterally, inwardly, .of this vchamber 16, openings are ,provided which are indicated by l17, and .these openings "are Y formedin the walls of they member 15, `so that the wateror other solution Yis directed inwardly perpendicularly to the axis of the nozzle. Iny the embodiment of Figs. 1 and2, i

threeopenings areuprovided. The ,jets'there-V bykformed mingle lwithin the'cavity18 and perform their .cleansing function. Y

j gradually` eXude over the .peak4 14 and. Ii .thereby come in contact with the body. and

In the embodiment shown in Figs. 3y Vand 4, the chamber 16 -is vreplacedby three communicating chambers 2O formedby the walls of thehead and intermediateofthese chambers depending portions 23, `which extend j inwardly of the tip ofv the head, so as tol form depressedp'ortions between the walls formingthechamber 20. yThe walls forming the chambery 2O are provided at the curved inward portion thereof k'with openings 22 which cause the Vjetsto be directed inwardly toward the aXis of the head. In the embodiment of Figs. 3 and 4, the three sov chambers 2O `are provided with jets that are formed and directed preferably, in cachinstance in a direction intermediate the two other chambers. This action of the jets is 'clearly shown in Fig. 5, in which each chamber 20has its opening 22 andeachjet of each chamber 20 is directed between the j other two chambers. By this` arrangement. the jets may be freeto project and impinge upon the parts of the body instead of'being merged and intermingled, as is the'case with Figs. 1 and 2. Instead of providing three suchchambers with one opening each, a

greater or less number yof chambers can of `course be provided andeach ychamber may of course have one opening but in each case clination of the Walls forming the openingsA so that that the jets will pass each other Without striking; this may be readily ac.- complished by a certain relativity of the inclinations of the respective Walls forming the openings. T he advantage of this form is that the jet may directly contact With the body Without having any of its forcellost as Would be the casev if the jets impinge upon each other. v 1

The heads which have been describedV in connection with Figs. 1;5v are substantially the saine as the part of the nozzle described ingconnection with Figs. 7 andV 8, andr in this case the Walls of the nozzle forming the ribs fhave such a contour that they form the Walls' of the chambersQO, While the Walls forming the end` of the'valleys l2 form thel depressed portions of the tip ofthe head and these depressed portions permit the jets to *pass so that the jets may impinge against f the body with their full force Without being diminished by striking any Wall of the head or striking any of the jets themselves. ln the embodiment shown in Fig. 6 the Walls ofthe nozzle are thus'so arranged that the Walls vofthe ribs .ll merge into the Walls forming the Chambers having jet openings and the Walls of the valleys form vthe intermediate portions depressed lin respect to the chambers 520.v

As stated,'one of the further important featuresY of the invention isV to have the Walls-of the jetopenings arranged so as to be .substantially perpendicular tothe axis `or at least in such a Way that the jets themselves do not'project directly outwardly of theftipY ofthe nozzle, along the axes thereof. The invention thus overcomes the use of devices Whichhave their openings directed -Y against the 'most delicatefand most likely to be injured parts Vof the body, the contact with which by foreign matter sometimes is a cause of death;v Whereas, the direction of the jets according to my imj'orovedinvention enables certain Aparts of the body to ber directly 'impinged vby the jets vvithout their coming into Contact with the moreV delicate parts just referred to. Y

' The heads vfor syringes embodying my in'- vention/ may be made either of glass or hardI rubber or other suitable material Well known to one skilled in the art. The manufacture thereof is inexpensive and the operation of the same is at all times under control. The

further advantage of my improved invenhavelostztheir 'pressure 'effect'acld SO Would 'not he injurious;

I have described and shown various em bodiments of my invention but l do not Wish to be limited thereto since the invention may be embodied in various forms,the spirit of the invention being delined by the appended claims. Y
