sirninen.

errlk r tiei fil MW 21 to minimize the number of parts and enable the same to be inexpensively manufactured and assembled; to enable the dilators to be made up as a single to utilize the res liency of the dilatorsto both return'themto norm alposition as well as. the rotating partby which they are operated; to provide a structure wherein said dilators normally assume a position closely adjacent to the body of the s-iyringe under the influence of theirown resiliency; to obtain a projection of the dilators away from the body portion by an action enablingithe device to be manipulated with one hand 5 to secure simplicity of construction and operation and to obtain other advantages and results as may be brought out in the following description.

Referring to the accompanying drawing in which like numerals of reference indicate similar parts throughout the several views;

Figure 1 is a side elevation of a syringe embodying my invention, showing the dilators in normal position;

Figure 2 is a similar elevation partly in section showing the dilators dilated; and

Figure 3 is an end view looking toward the top of Fig. 2. V

In the specific embodiment of the invention illustrated in said drawing reference numeral 1 indicates an outer body portion which is preferably elongated and tubular and slid ably mounted upon an inner body portion 2 which is likewise tubular and equipped at one end with a bead 3 for receiving and holding a water tube 4 to enable a supply of water to be passed through the said inner body member 2 as is usualin syringes. The other end of the tubular body portion 2 is provided with a fountain head 5 suitably perforated so as to provide for proper spray when the water 1s passed through it. In the construction shown in the drawing, this fountain head 4 is preferably screw-threaded on to the end of said body portion 2. The inner body ortion is preferably longer than the outer b0 y portion and is rotatable thereon and prevented 1927. Serial No. 193,249.

from any sliding in a directionaway from the fountain head by an outstanding shoulder 6 nearthebeadedend of said inner body meins ber, and held against slidin in the other direction by interposition ofdilators between the end of said body portion and. said fountain head 5 which is larger than the inner body member.

ou ted Q th d o ride t-i bo y member adjacent the fountain head. arc/film} rality of dilators 7, said dilators preferably being made of resilient rubber with integral collars or bands 8, 9 at opposite ends oftl e several dilators one of which. bands, as 8, will frictio ially slip onto the uppere id of said outer body member and retain said dilators fixed thereto, and the other band 9 frictionally slip onto the inner body member below the fountain head. The dilators and collars formed integrally as indicated form a sleeve with an outside diameter substantially that of the outer body member so said sleeve forii s a continuation of said body memberi It may be pointed out at this time that one end of this sleeve is fast to the outer end of one body member and the other end of the sleeve is fast on the other body member so any relative rotation of one member with respect to the other will be resisted by the resiliency of the sleeve of which the dilators are a part. The resiliency of the dilators and sleeve is such as to normally position the dilators side by side against the inner body member or water tube. Said sleeve is slit, as at 10, at successive intervals around itself, said slits extend ing diagonally or spirally of the sleeve and constituting the divisions between the dilators 7. Attempt to rotate the outer body member in one direction will merely tighten these dilators against each other and resist the turning of said member, but turning of the said body member in the other direction meets no such resistance and the dilators will bulge outward as their opposite ends approach longitudinal alinement, this position being clearly shown in Figures 2 and 3, and for brevity being called herein the dilating position. When the user releases the outer member, after having rotated it to obtain dilation of the dilators, the resiliency of the dilators causes the said member to turn back to normal position as shown in Fig. 1, with the gilators again close to the inner body mem- The inner body member 2 is perforated below the fountain head within the confines of the fingers, as at 11, preferably at such position as to be substantially opposite the peak of the bulge of the fingers when they are bent outward to their greatest extent. These perforations open through to the water passage in said body member and obtain a spray of water outwardly through the fingers when the same are dilated.

Obviously other detail changes and modifications may bemade in the construction and use'offmy improved syringe without departing from the spirit. and scope of the invention disc'losed,andI do not wish to be understood as. limiting myself to'the exact conable and longitudinally stationary with rea spect to each other, and dilators carried by one'of said'bodymembers and so restricted Ly the other member as to be bent outwardly when the said body members are rotated with respect to each otlierin'one direction.

'2'. A device of the character described comprising inner and outer body meng bers rotatable and longitudinally stationary with respect to each-ot-heijand dilators secured at opposite ends to said bodyimembers so opposite ends of said dilators will be oppositely rotated relatively by a relative opposite rotation of said members for bending said dilators outward upon rotation of said body members in one direction.

3. A device of the character described comprising an inner body member having a shoulder at one end and a fountain head at the other end, an outer body member rotatable on said inner body member and prevented from sliding by said shoulder, and dilators secured at one end adjacent said fountain head and secured at their other ends to said outer member and adapted to be dilated by rotating said members with respect to each other.

4. A device of the character described comprising a pair of rotatable members, diagonally disposed dilators attached at opposite' ends to said members whereby relative rotation of the members in one direction will cause said dilators to bulge outwardly.

5. A device of the character described comprising a pair of rotatable members, and a resilient member attached at its opposite ends to said rotatable members respectively, said resilient member having portions thereof which will bulge by relatively rotating one end of said resilient member with respect to the other.
