This invention relates to'syringes and more particularly to mechanically dilated vaginal syringes and the method' of making the same. The objects of the invention are to provide a syringe of this character wherein the mechanical .dilation may be secured by relative movement of slidable parts; to employ improved fiexible dilators for dilation by said slidable parts; to employ dilators properly q made of such materials as molded rubber so as not to be 4injurious in use; to minimize the number of parts and enable the same to be inexpensively manufactured and assembled; to utilize the resiliency of the dilators to both secure the proper shape when dilated and return them to normal position when released; to provide a structure whereinsaid dilators normally assume a position closely adjacent tothe body of the syringe under the iniiuence of their own resiliency; to obtain a projection ofJ the dilators awa `from the body portion by means enabling t e device to bemanipulated with one hand; to permit rotation of the 'dilators with res ect to the body 5 members; to enable the use o? the device for medical urposes; .to permit ejection of dry powder rom the nozzle end of the device; to secure simplicity of construction and operation and to obtain other advantages and results as maybe brought out in the following description. y
Referring to the accompan ing drawing in which like numerals of re erence indicate similar parts throughout the several views Fi re 1 is a side elevation of a syringe embodying my inventibn, showing thefdilators in normal position;
Figure 2 is a similar elevation showing the dilators dilated;

Figure 4 is a sectional view on line 4 4 of- Fig. 1; I
igure 5 is a sectional `view on line 5--5 of Fig. 2; J Y j' Figure 6 is an end view of the outer die for making the dilators;
Figure 7 V's a similar/end view of the inner die or core for making said dilators; A Figure 8 is an end view of said inner die or core'in course of manufacture thereof; and
Figure 9 is an elevation of a certain plunger to be used in connection with my invention.
In the specific embodiment of they invention illustrated in said drawing reference numeral 1 indicates an outer body portion which is preferably elongated and tubular and slidably mounted upon an' inner body portion 2 which is likewise tubular and equippediat one end with a bead 3 for receiv# infr and holding a water tube 4 to enable a supply of water to be passed through the said inner body member 2 as is usual in syringes. The other end of the beaded section of the tubular body portion 2 terminates within the outer member and is screw threaded to receive the shank of a fountain head 5 suitably perforated so' as to provide for proper spray when the water is passed through it. This main orfbeaded section of the tubular body l portion and the fountain head 5 are preferably secured permanently together in manufacture so the user never has them apart, and
'will be referred to herein jointly as the tubular body portion. This tubular body portion is preferably longer than the outer body portion and is rotatable thereon and prevented from sliding out of the outer member atthe fountain head end by an inwardly directed shoulder 7 on the outer body member around the shank 6 of the tubular member and overlying the end 8 of the main section of said tubular member.
Mounted on the end of said outer body member adjacent the fountain head is a ilexible sleeve 9 providing a plurality -of dilators 10, said sleeve 9 preferably being made of resilient material such as rubber with the dilators 10 integral with collars or bands 11 12'v at opposite ends of the several dilators. ne
'of these bands, as 11, its rotatably onto a tent.
The dilators and collars formed integrally as indicated form a sleeve with an outside diameter substantially that of the outer body member so said lsleeve yforms a continuation of the outer surface of said body member. The resiliency of the lingers and sleeve is such yas to normally position the lingers side by side against the. inner body member or water tube. Because of the interior shoulders, the outer member canslide no further in a direction away from the fountain head end of the device Ithan to permit the sleeve to be just in its normal cylindrical condition, but in the other direction the outer member meets no such shoulders and may be slid, as a result` of" which thedilators will bulge outward as their opposite ends approach each other, this position being clearly shown in \Figur`s 2 and 3, and for brevity being called herein the dilating position. When the user 4releases the outer member, after having slid it to obtain dilation of the dilators',the re siliency of the dilators causes the said member to return to normal position as shown in Fig. 1, with the dilators again close to the inj ner body member.
The inner body member or sl1ank6 thereof is perforated below the fountain head within the coniines of the sleeve, as at 14 preferably at such position as to be substantially opposite the peak of the bulge of the dilators when they are bent outward to their greatest ex- These perforations open through to the water passage in said body member and obtain a spray of water outwardly through the lingers when the same are dilated.
In order to provide means for sliding the outer member with respect to the inner member, particularly by a means which can 'be operated by one hand, I show in the/drawing an operating yoke 15. This yoke is so arranged that one part'of it is carried rotatably and non-slidably on the end of the outer member away vfrom the sleeve, andan l opposite part of the yoke is carried also rotatably and non-slidably by the inner member adjacent the beaded end thereof. Consequently by compressing the intermediate l parts of the yoke 15 toward each other a moment of force is set up establishing a relative sliding movement between the inner andouter members as clearly illustrated in comparing Figures 1 and 2. As shown, the rotatable and non-slidable attachment of the yoke to the said members is accomplished by spaced circular ribs 16, 16 on the outer body member and similar spaced annular ribs 17, 17 on the inner body member, the yoke titting between the ribs with suiicient play to enable the same to rotate without binding upon the body members'. Preferably the yoke is ef resilient material, such as rubber, and has a normal shape such as shown in Figure 1 as to tend to slide the body members together with shoulders 7 and 8 in engagement.
However, the user may very readily press the bow portions of the yoke together and slide the upper member and sleeve to dilating position, and immediately on release of the pressure on the yoke, its inherent resiliency together with the resiliency of the dilators returns said members to normal position with the shoulders 7 and 8 again in engagement.
JI desire to point out at this time that in the construction of my improved syringe that I provide dilators which bend immediately under the button head of the device when the dilators are forced into dilating position. This release in the dilators having an extreme dilation at a point very close to the head of the instrument. To accomplish this purpose I provide the slits in the sleeve as close to the end of the sleeve as practical and reenforce the dilators with as much material as practical so the bending of the dilators will tend to bend and Stretch the collar at .the outer end of the instrument rather than bending the dilators adjacent the collarC In this action, it may also be pointed out that the collar is preferably shaped so that it will have minimum engagement with the inner mem-A ber and thusnot interfering materially with the independent rotation ofthe member with respect to said collar in any position of the dilating sleeve. Likewise the dilators are preferably rounded both inside and out as clearlycshown in Figure 5 so as to eliminate anysharp edges and to provide on the inner faces of the dilators surfaces which will defleet the jets of water rather than flat surfaces which would interfere with the jets performing a useful purpose.
The device is particularly adapted for medical purposes, in that I amenabled to inject medicine in powder form into the human channels. To do this, the powder is inserted into the centralbore of the device down to the perforations 14, but cannot pass out of the instrument because of the surrounding sleeve. no The doctor may hold and inject the instrument and with the same hand then dilate the dilators. A plunger 21, already partially inthe finished sleeve. I also provide a core or inner die 19 the outside diameter of which is such that it substantially fits within the outer core. This inner die or core is` preferably made by' drilling parallel holes 20 therein of a diameter substantially the width 13o of the dilators and spaced in the relationship Nthat` the dilators are to have. This blank in which these holes are made is preferably larger than the die is to be when completed, and after the holes are drilled then the blank is turned down, partially exposing the drilled holes at one side. The operations are such that the blank is turned down less than the distances of the center of the holes whereby the holes left in the iinished core are more than semi-circular. The core is inserted in the outer die andrubber is pressed therein thereby getting a curved inner surface as well as curved inner edges to the dilators at the outer surface of the sleeve.
Obviously detail changes and modifica-i tions may be made in the construction and use of my improved syringe without departing from the spirit and scope of the invention 3 disclosed, and I do not wish to be understood memb as limiting myself to the exact construction except as set forth in the following claims when construed in the light of the prior art.
