SYRINGE Specication of Letters Patent.
Patented Feb. 9, 1909.
Application filed January 4, 1901.k Serial No. 42,139.
vented a certain `new and useful Syringe, of
which the following is a specification.
My invention relates to syringes wherein liquid, and especially ready for immediate use, maywith convenience and safety be carried in the pocket and usedV in definite quantities; yand to this end, the invention consists, essentially, in the combination, construction and arrangement of the parts hereinafter set forth and pointed out in the claims.
In describing this invention, reference is had to the accompanying drawing, in which like characters designate corresponding parts in all the views. y
Figure l isa longitudinal fview of my syringe, the inclosing member,- or Acase andV the stopper being shown in section.`v` FigQ is a longitudinalV view of the inclosing inemloer or case, a portion thereof'being in section for illustrating the stopper. Fig. 3 is a longitudinal view showing the detached font, partly filled with liquid, andthe piston arranged about midway between theends of the font. Fig. seis a longitudinal view of my syringe, a portion of the inclosing member, a case being in section, and the cover thereof being omitted and the font having its port closed vby the stopper. Fig. 5 is a view of the part seen in F ig. '11, the pistonV being illustrated: in the same position as in Fig. l. Fig. 6 is a view similarto Fig. A, liquid being illustrated on opposite sides of the piston. Fig. 7 is an elevation ofthe detached stopper. Fig. 8 is a sectional view online Ill- A2, Fig. 7. tudinal sectional view of the stopper. 10 is an elevation of the piston and a portion of its stem. Fig. l1 is a face view of the piston. F ig; 12 is a vsectional view on line jL/-i Fig. 11. A
In the drawings, A'represents the inclosing member or case provided with a cap B,
and C designates the font or cylinder provided with aport C at one end thereof, said port C serving as an inlet and an exit and being normally closed by a stopper D,
which is arranged in one end of the inclosing member or case A and formed with a cup 0 for receiving the end of said port.
medical solution Fig. 9 is a longi-` Fig.`
E is a piston provided with a rod F movto the port C. Said case A and font C are obviously of-any desirable form, size and construction.
G designates the liquid within the font A. Said `liquid is transferred within the font from either side of the piston to the other, the illustrated means for effecting this result being suitable conduits as capillary tubes a b passing through the piston.
In the use of my syringe, a medicinal solution, or other liquid, is filled within the Vfont through the port C by moving the piston E from said port. The font A is then inserted into the inclosing member or case until the port enters the Vcup 0 and is closed by the stopper D, whereupon said font is held in this position and the piston E is moved slowly in the reverse direction until it encounters an engaging face Within the font at the base of the port C and is thereby prevented fromfurther movement. The cap B is then placed in position and the inner face thereof engages the outer end of the piston rod, and owing to the engagement of said inner face of the font by the piston, the font is firmly held in position with its port closed, and leakage of the solution or liquid is prevented. When it is desired to use a predetermined amount lof the solution, the cap is removed, the font is firmly held in position with its port closed by the stopper D, and the piston E is slowly withdrawn until the predetermined quantity of solution has been transferred from the back of the piston to the front thereof. The font is then withdrawn from the member D and the solution in front of the piston is expelled through the port C by movinglthe piston toward said font. n The parts may be manipulated as described, until the solution is entirely discharged.
The construction and operation of my invention will now be readily understood upon `reference to the foregoing description and s to be transferred from either side of the able through the end of the font opposite Without passing` -he liquid out of the font piston to the other, said means being` operable independently or lehe stem of the piston7 substantially as and for the purpose described.
2. n a syringe, a font, a piston movable in the font, a stem associated With the piston, and means between the portions of the interior of the font at opposite sides of the piston for transferring the liquid in the font from either side of the piston to 1@he other 7 said means being operable independently of the stem o1 the piston and being inoperative When the liquid is permitted to pass from the font under pressure of the piston, substantially as and for the purpose specified.
3. A syringe piston for dawing in and expelling` liquid from the font of the syringe, provided with a capillary tube extending; longitudinally through the piston and adapted to allow the liquid to be transferred Within the font of the syringe from one side of die pision to the other, substantially :xs land for the purpose described.
el. ln a syringe, a font, a pisi'on movable t' in the ioin'; for drawing` the liquid therein and expelling the liquid l'hereirozn, `said piston having;` u stein associaed iherewilh, und being provided with means 'lor perniiting the liquid *io pass through ihe piston 'from either side rhereoilt to the o'her, said nnuns being operable independently or i'he stein of the pisloin and being; innpuruife when (he liquid is perinii'ed 'o pass ironi the foul under the pressure of he pision, substantially as and for lhe purpose sei' forth.
lin tevsl'inlony whereof lV hare hereunto sei' my hand ai the city of Hyraruse, N. Y. in the presence of iwo subscribing u'it'xwsses, this @lili day of Decendier, 1900.
