SPECIFICATION forming part of Letters Patent No. 594,721, dated November 30, 1897.
Application filed July 31,1896. Serial No. 601,131. (No model.) Patented in France February 1, 1895, No. 244,794.
1'0 aZZ whom it may con/corn.
Be it known that I, J ULES BEN GU1 of Paris France, have invented a new and Improved Sprayer, (for which I have obtained Letters Patent in France, No. 244,794, dated February 1, 1895,) of which the following is a full, clear, and exact description.
My invention refers to spraying devices for ethyl chlorid and other volatile liquids.
My present invention relates to apparatus of the above-indicated class in which a capillary discharge-opening is employed witha protecting-filter, but in which instead of the ordinary closing-valve having a movable plug I make use of a washer of some suitable soft material inclosed in a metallic cap, said washer being pressed against the orifice of the capillary opening by means of a spring and intermediary mechanism, such as levers. By this means I obtain an apparatus which may be very readily manipulated and at the same time may be tightly closed.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a side elevation of the improved sprayer with the outlet closed. Fig. 2 is a similar View thereof on a reduced scale, showing the manner of manipulating the apparatus for opening the outlet; and Fig. 3 is a broken sectional elevation of the dischargenipple and parts connected therewith.
I will first describe the construction of my improved sprayer and then point out its novel features in the appended claims.
The liquid is discharged from the apparatus through a capillary opening of uniform diameter, which is provided directly in the neck of the receptacle when the same is made of glass or the capillary opening may.
cessively two communicating chambers or funnels, of which the outer chamber 1) remains empty and serves as a reservoir to prevent an intermittent discharge of 1iquid,while the inner chamber 1) is filled with cotton or other suitable material adapted to act as a The rod a is fitted into the sleeve or nipple c of the tube D, which screws on. the screwthreaded upper end g of the receptacle A, and a washer f, made of soft metal or of rubber, is interposed between the said end 9 and a shoulder of the tube D, said washer also engaging the glass rod a, so as to produce a tight joint.
On the upper portion of the receptacle A is f ulcrumed an elbow-lever Z, carrying at one end a cap m,containing a compressible washer :10, madeof rubber or equivalent material. The other arm Z of the lever is pivotally con nected to a rod 25, the lower end of which is screw-threaded. On said screw-threaded end is fittedv a nut :3 which receives one end of a coil-spring 0", arranged within a casing 25, which is secured to the receptacle A. Preferably the lower end of the casing 15 is provided with a thumb-piece 2, as shown. In order to enable the apparatus to be filled, I provide the same with a nipple p at the bottom, said nipple being normally closed by means of a cap q, provided with a handle q.
The operation of this apparatus is as follows:
In the normal position of the parts, as shown in Fig. 1, the spring 1" forces the rod 25 upward, and thus presses the cap m, with its washer so, down upon the orifice of the capillary passage 0. When it is desired to produce a spray of liquid, the operator takes hold of the apparatus in the manner indicated in Fig. 2, the thumb-piece being engaged by the thumb,while two fingers of the operator rest on a small transverse bar or pin h, secured to the rod 25. It will be obvious that by drawing said bar downward the operator will remove the cap m from the outlet of the receptacle, and thus the liqu idlunderitvsifll ressure will pass out through the capillary passage 0. Whenever it is desired to arrest the discharge of the liquid, the operator simply releases the rod 15, when the spring 7 will instantly close the outlet.
Having thus fully described my invention, I claim as new and desire to secure byLetters Patent-- 1. The combination with a spraying apparatus having a capillary discharge-orifice, of
a yielding cap movably connected with the apparatus and adapted to close the outlet thereof, a spring for pressing the cap upon the outlet, and a sliding bar or handle for removing the cap from the outlet against the tension of the spring, substantially as described.
2. Inasprayingapparatus,the combination with the receptacle, of a pivoted cap adapted to close the mouth of the receptacle, and a spring-pressed sliding rod connected with said cap, substantially as described.
3. In a spraying apparatus,the combination with a receptacle, of an elbow-lever pivoted upon the receptacle, a cap carried by one member of the lever and adapted to close the receptacle, and a spring-pressed sliding rod pivoted to the other member of the elbow-lever, substantially as described.
4. In asprayingapparatus,the combination With a receptacle, of an elbow-lever pivoted on the receptacle, a cap secured to one member of the lever and adapted to close the discharge-passage of the receptacle, a casing secured to the receptacle, a rod secured to the other member of the e1bow-lever and projecting into the casing, and a spring between the end of the rod and the bottom of the casing, substantially as described.
5. Inasprayingapparatus,the combination With a receptacle, of a tube secured to the upper end'of the receptacle and provided with a shoulder, a glass rod provided with a capillary discharge-passage having two communicating enlargements at its inner end, and a Washer interposed between the shoulder of the tube and the top of the receptacle and engaging the glass rod, substantially as described.
In Witness whereof I have hereunto set my hand in presence of two witnesses.
