P. N. CONDIT LIQUID APPLICATOR Fil'ed March 5l 1924 Patented Feb. 16, 1926.
Unirse STATES PARK N. CONDIT, OF BOSTON, MASSACHUSETTS.
LIQUID .APPLICATOR.
Application 1ed March 31, 1924.
Y o all whom t may concern.'
Be it known that I, PARK N. CONDIT, a citizen of the United States, residing at Boston, in the county of Sutt'olk and State of Massachusetts, have invented certain new and useful Improvements in Liquid Applicators, of which the following is a specilication.
struction, readily amenable to cleansing and sterilization and having associated with it applicator points having the qualities of transparency and flexibility, permitting distribution ot' the liquid into cavities diticult `of access and without danger of damage to the transparent but rigid portion of the apparatus or the parts to which it is applied.
A further aim is in the provision of means, including a needle-like brush, for making the most delicate applications of minute quantities of liquid with precision to parts requiring such applications.
A still further object is to provide a receptacle, particularly designed to contain a small quantity of the liquid to be used, into which the point of the applicator may be inserted, thus avoiding waste of material, said receptacle having on its edge, means for supporting the instrument during intermission of operation.
These and other analogous aims and objects are accomplished by the novel design, construction and combination of parts hereinafter described and shown in the accompanying drawing, forming a material part of this disclosure, and in which Figure 1 is a side elevational view of an embodiment of the invention, shown in position of rest.
Figure 2 is a partial longitudinal sectional view of vthe same, drawn to an enlarged scale.
Figure 3 is a sectional view of the com- Seral No. 703,182.
bined liquid container and instrument support in detail.
Figure is a partial side, partial sectional view of one of the flexible applicator point elements before trimming.
Figure 5 is a side view of the same as trimmed ready to attach to the nozzle of the instrument.
Figure G is a partial side, partial sectional view of the same, showing the brush element engaged therein.
Figure 'i' is a side view of the needle brush in detail.
As shown in the drawing, the instrument is composed of a small cylindrical solid glass rod 1() having a smoothly1 rounded outer end, its inner end 11 being slightly enlarged and fused to a tube 12 presenting a chamber 13.
Said tube is drawn straight outward to form a conical element l-l and preferably bent at a right angle which constitutes a noazle 1:3, there being a tine opening extending throughout from the chamber 13.
A tubular extension 17 also communicates with the chamber 13, said extension leading rearwardly heilig spaced adjacent the body 10.
l? used with the body 1() is a solid projection 18, bent to extend forward, in register with the tube extension 17, with which it agrees in outer diameter.
A flexible tube 19, as of rubber, has its ends forcibly engaged over the adjacent ends of the tube 17 and projection 1S respectively.
flt will now be apparent that if the wall of the flexible tube be compressed, as by placing the linger of an operators hand upon it, and pressing the tube against the glass rod 11, with which it is parallel and normally in contact, the air in the tube will be forced out and expel any liquid which may be containedin the chamber lll or conical tube leading therefrom.
Conversely, upon allowing the tube 19 to assume its normal cylindrical condition, and having the end of the nozzle 15 disposed in a liquid, the liquid will be drawn into the tube and chamber, in accordance with the partial vacuum produced by eX- pansion of the tube 19.
In order to provide a particularly etlective container for supplying liquid to the nozzle the device shown in Figures 1 and 3 is used.
This container is composed of a flanged base 20 from which rise cylindrical Walls 21, curved `at their upper portion 22 and then brought convergingly inward to the inverted apex 24, the same being suited to hold even a single drop of liquid so that it can be received in the nozzle 15 Without loss.
In addition, the upper rounded edge 22 is provided with a pair of spaced upstanding` rounded projections or knobs 25 adapted to receive between them the coned portion of the instrument, as seen in FigureV 1.
These containers may be made transparent or in colors, each color .signifying the particular variety of liquid to be used therein and acting to readily identify same.
The applicator; points, shown in detail in Figures 4 and 5, consist of hollow conical bodies 26 having, in their original shape, a Widely coned head2? and a straight cylindrical opposite end portion 28, thisbody having a trumpet shape.
These applicator points are preferably made of material havingthe properties of translucency and flexibility, as celluloid and are trimmed at their ends, as in Figure 5, to be readily applied over the nozzle 15 and adhere until forcibly removed, the extending portion of the applicator points being conformable to requirements.
The needle brush element 29 shown in det-ail in Figure 7, is a finely tapered cone of highly absorbent fibers or filaments, suited to enter the applicator points, the point 30 of the brush being trimmed back if desired to present a soft pliableV contact, and convey liquid as required, the lliquid being acted uponby capillary attraction, or forced by compression of the tube 19.V
ItV Will be apparent that the needle brushes and applicator points are intended for use once only and then replaced or substituted by others, their cost being negligible.
In Aorder `to sterilize the instrument, the tube 19 may be removed and the glass body subjected to such treatment as may be preferred. Adthough I have described my improvements With considerable kdetail and With respect to certain particular forms of my invention, I do not desire to be limited to such details since many changes and modifications may Well be made Without departing from the spirit and scope of my invention, in its broadest aspect. l
kHaving thus described my invention, what I claim as new and desire to secure by Letters Patent, js:- .l
l. A liquid yapplicator comprising a solid rodhaving a chamber at one end, a contracted conical tube leading therefrom, said tube being bent at an angle near its end, a rearwardly turned tube communicating With the mentioned chamber disposed adjacent said rod, a forwardly turned projection on said rod in register Wit-h the last named tube, and a flexible tube connected at its ends With the last named tube and said projection respectively, said flexible tube being substantially parallel With and in contact with said rod.
2. A liquid applicator comprising a solid rod having a chamber at one end, a transparent conical tube communicating with the chamber and extending in register with said rod, a cylindrical tube communicating With the chamber and bent to extend rearward adjacent the rod, a flexible tube engaging the open end of said cylindrical tube, means for plugging and supporting the opposite end of said tube, and a nozzle on the end of said conical tube bent to extend at an angle relative to the tube.
3. A liquid applicator comprising a glass bar having a chamber at one end and a conical tube leading therefrom, said bar extending' oppositely to constitute a handle; means carried on said rod at the side thereof for expelling or drawing liquid relative to the chamber, and a bent nozzle on the end of said conical tube. l
ll. A liquid applicator comprising a solid glass rod having a chamber at one end anda conical tube leading therefrom, means carried on said rod p rallel therewith for entering or expelling liquidY relative to the chamber, a nozzle'disposed at an angle on said conical tube, and a hollow flexible transparent applicator point removably engaged on said nozzle.
5. A liquid applicator comprising a glass rod having a chamber at one end and a conical tube leading therefrom, means carried at the side of said rod for entering or expelling liquid relative to the chamber, and a flexible applicator point removably engaged on the end of said conical tube.
6. A liquid applicator comprising a glass rod having a chamber at one end and a conical tube leading therefrom, means carried on said rod for entering` or expelling liquid relative to the chamber, a hollow flexible and transparent applicator point engageable over the end of said conical tube, and a highly flexible. foraminous brush engaged Within said applicato-r point to extend therefrom.
7. In combination with an applicator of 4the class described, of a transparent conical tube adapted to engage over the discharge end of the applicator, and a needle pointed fibrous brush adapted to enter and extend through said tube,
VIn testimony whereof I have signed my name toV this application.
PARK N. CONDIT.
