To all whom it may concern Be it known that I, EDWARD H. KoHNnN, a citizen of the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Syringes, of which the following is a full, clear, and exact description, reference being bad to the drawings, forming a part of this specification.
My invention relates to syringes or sprayers and particularly to the provision of means which greatly facilitates the filling or charging of the syringe from a bottle.
The difficulty presented to physicians and more particularly to individual users of syringes or sprayers lies in the difficulty of filling them with the liquid to be used since it is impractical ordinarily to insert the nozzle of the syringe down into a bottle or other liquid container far enough to reach beneath the surface of the contents thereof. It is also not possible, so far as I am acquainted with past devices, to get the liquid all out of a bottle or container, by sucking it up into a syringe, since the tipping up of the bottle will entirely prevent the chance of reaching the liquid with the syringe nozzle, without spilling the. liquid in so doing.
It is thus the object of my invention to provide syringes generally with means whereby their nozzles can be set in the neck of a bottle to stop it up entirely, in the nature of a cork, so that the liquid may be safely sucked up into the body of the syringe by the operation of the piston or plunger thereof.
This object and other advantages to be noted I accomplish by that certain construction and arrangement of parts to be herein after more specifically pointed out and claimed.
In the drawings,
Figure 1 is a longitudinal section taken through a syringe, selected for purposes of illustration of my invention.
Figure 2 is a side elevation of a like syringe showing my device and a slightly different method'of attachment of the parts.
As shown in the syringe of the drawings there is a barrel or body 1, which has at one end the closure or cap 2 which is threaded in place, and supports centrally the rod 3 for the piston or plunger 4:. The rod has a handle as at 5.
The inner end of the syringe, shown, has a reduced portion 6, Figure 1, intermediate the end of the barrel or cylinder 1 and the nozzle 7 In Figure 1 this reduced portion is shown as integral with the barrel and the nozzle.
In Figure 2, where the parts are broken away, the end of the barrel is shown as reduced, and threaded, at 8, and the nozzle 9 has integral with it the neck 10, which is interiorly threaded to secure onto the end of the portion 8 of the barrel. 7 p
In either instance, there is, of course, a passageway from the barrel to the nozzle, so that upon the movement of the piston in the cylinder of the device, there will be either pressure or suction directed toward the nozzle from the cylinder.
In the first instance, formed around the reduced portion or neck 6, and in the second instance, as a separable body merelyset over the neck 10, I providea tapered soft rubber member 11, fitting against the nozzle. While shown as tapering from the nozzle to the barrel in such a way as to make a smooth fit to each part, this is not absolutely necessary, except from the point of view of appearance, and while preferably made of soft rubber, some other material which was water tight, and inherently resilient to a similar degree would serve the purpose. The member 11 should form a liquid tight fit with the nozzle or barrel to prevent leaking around the reduced neck.
Due to the. fact that the member 11 is of clinging or resilient material, and tapered, it will fit a fairly wide range of bottle necks, and when inserted into the neck of a bottle it will securely seal or stop off the flow of liquid therefrom except through the nozzle of the syringe.
Thus in the use of my device, the nozzle of the syringe may be inserted into the neck of the bottle, to bring the soft tapered portion into a sealing or stopping position, whereupon the bottle may be tipped up, and the plunger of the syringe operated to suck the required liquid into the barrel. The bottle may then be tipped back to its proper position, and the syringe withdrawn, and
used.
My invention will be of greater advantage in small pump syringes than in the many other instances where it will be valuable, since such syringes require a fresh filling and complete discharging each time they pered nozzle on the end of the extension of are used. greater Width than the extension but in- 1 Having thus described my invention, What tegral therewith, and a tapered soft rubber I claim as new and desire to secure by Letbody mounted on the extension and filling 6 ters Patent is I the space between the tapered nozzle and In a syringe a barrel, a piston insaid the barrel wall. barrel, an outlet from the barrel, an extension from the barrel of reduced Width, a ta- 7 I EDWARD H.
