CAP FOR FOUNTAIN OR OTHER SYRINGES.

EVERETT H. BICKLEY, OF PITTSBURGH, PENNSYLVANIA.
CAP FOR, FOUNTAIN OR OTHER SYBINGES.
Specification of Letters Patent.
Patented Nov. *7, 1916.
Application filed June 19, 1916. Serial No. 104,546.
To all whom it may concern:
Be it known that I, EVERETT H. BIOKLEY, a citizen of the United States, residing in Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Caps for Fountain or other Syringes, of which the following is a specification.
This invention relates to improvements in caps for fountain or other syringes or bags having hose connection therewith. The ordinary cap used in such syringes consists of a plug having an external threaded portion to screw into the internal threaded neck of the bag. Integral with this threaded portion is carried a flattened portion for a grip, while turning, also a tube-like extension, to hold the hose. At the lower end is a rubber washer. The act of screwing the cap into the bag, twists the hose, and puts a pinching and rubbing action on the washer that wears it unduly.
The object of my invention is to provide a cap which may be screwed into the bag neck without twisting the hose, and without imposing any other force than compression on the washer.
In the drawings Figure 1 is a side sectional View of the cap, showing the detailed construction. Fig. 2. is a view similar to Fig. 1. not in section but showing another side at right angles to Fig. 1. Fig. 3. is a view showing an application of the cap to a combination fountain syringe bag.
In Fig. 1. a are the wings for turning or screwing the cap into the internally threaded neck of the syringe bag. 6 is the locking disk which holds the entire outer shell together, being crimped on. c is a heavier metal washer to which the wings a are riveted. d is the drawn metal shell having formed in it the threads for screwing into the neck of the water bag or syringe. These four parts a, b, a and d form one assembly, which fits freely over the tube 9 which is flanged at the lower end. 6 is a thin metal washer. f is a rubber washer, which fits snugly over the tube 9. h is a ring which is a tight press fit over the tube. This ring is applied last and is pressed into position so that the outer shell is held on the tube but is free to rotate on it.
Figs. 2 and 3 are self explanatory. It will be seen that the hose tube 9 and washers e and f will turn freely on the shell assembly a b c d, so that as the shell is turned by the wings a the tube and washers will not rotate but are pressed forward making a water tight joint in the neck of the syringe with a minimum pressure on the wings a and with the least wear on the threads, and washer, due to the smaller forces and less friction being involved. The action of the washer e partially expands the rubber washer f thus forming a joint, and also takes the wear off the rubber and decreases friction, which is encountered immediately in the old style as soon as the rubber meets the seat. The depression in the top of the tube 9 is for attaching the hose.
IV hat I claim as my invention is 1. In a syringe cap, the combination of a threaded shell; a washer carrying thumb wings; a locking disk crimped on the shell embracing the winged washer; a tube having a flange on one end. and a means for hose connection on the other end, passing through the shell; and a packing washer surrounding the tube between the flanged portion and inner end of the shell, substantially as described.
2. In a syringe cap, the combination of a threaded hollow plug; a hose connection tube passing through said plug; and means for rotating the plug independent of the said tube.
3. In a syringe cap, the combination of a threaded apertured plug; a hose connection tube passing through said plug, the inner end of said tube being flanged; a washer int rmediateof the inner end of said plug and flanged portion of the tube; and means for rofiating the plug independent of the said tu e.
4. In a syringe cap, the combination of a threaded hollow plug; a flanged hose connection tube passing through said plug; a packing washer intermediate of the plug and flanged end of said tube; a relatively hard washer backing up the first mentioned washer; and means for rotating the plug independent of the said tube, substantially as described.
