SPECIFICATION forming part of Letters Patent No. 614,744, dated November 22, 1898.

Application filed September 20, 1897. Serial No. 652,229. (No model.)

To all whom t may concern.-

Beit known that I, FREDERICK W. NET- TLETON, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvementin Sprayers; and I do hereby declare the following', when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure l, a sectional view of a sprayer embodying my invention; Fig. 2, a side view of the nipple detached; Fig. 3, a side view of the flexible valve-ring detached, and Fig. et a sectional view on line 4. 4 of Fig. l.

This invention relates to an improvement in sprayers, and particularly to that class in which the liquid is contained in a flexible bulb, by the compression of which the contents is ejected through thev nozzle. While the device is applicable for many purposes, .it is intended for the use of bicycle-riders for throwing ammonia or other liquids at dogs or other troublesome animals.

The object of the invention is to produce a simple device which may be readily operated and from which the liquid in the bulb may be ejected without inverting the bulb 5 and the invention consists in the construction, as will be hereinafter described, and particularly recited in the claims.

For convenience of illustration I have shown the device upon an enlarged scale, but the bulb A will be formed from flexible rubber and of a size convenient to be grasped in thehand and, if desired, carried in the pocket. The bulb is oval or contracted at its ends, and in one end is inserted a nipple B, having a central passage, which is enlarged at the upper end, forming a seat b. Midway of its length is an annular flange C, against the under edge of which the upper edge of the bulb will be seated, and preferably the lower end of the nipple will be formed with an annular shoulder D, over which the neck of the bulb vwill be drawn to secure atight joint between the nipple and the bulb, which may be cemented, threaded, or otherwise secured. The upper end of the nipple is exteriorly threaded,

lthrough the outer endof the nozzle.

and upon one side the surfaceis flattened, as at d, and through the flattened side of the nipple is a hole or perforation c. In the upper end of the nipple is located a ring E, of flexible rubber, which is supported in position by the shoulder l). This ring closelyfits the interior of the upper end of the nipple and so as to normally close the hole e. Preferably the lower end of the ring E, beneath the hole c, will be formed with a notch F, the purpose of which will hereinafter appear. The nozzle G will be provided with a collar II, interiorly threaded for engagement with the nipple, and the stem passes through the nipple and is of such a length as to extend into the contracted lower end of the bulb. Preferably the outer end of the nipple will be curved and adapted to receive a closing-tip I. This tip may be of rubber and so as to frictionally engage with the end of the nozzle, or may be made of metal and threaded for engagement with threads on the end of the nozzle, and for convenience the tip I will be connected by a chain or cord J with the nozzle G or collar H.

IVhen it is desired to use the device, the tip I is removed, and if it is made of rubber this can be conveniently done by striking it against a part of the cycle. Then upon the compression of the bulb the material therein will be forced outward through the stem and ejecticld As t e bulb is th-us compressed the material or air in the upper end of the bulb will be forced against the inner surface of the rubber ring E and press that ring against the inner wall of the nipple, so as to positively close the hole e therein; but when the-bulb is released the pressure upon the ring is relieved and so that air may enter through the hole c and pass downward between the inner Wall of the nip- 'ple and the outer wall of the ring and escape beneath the lower end of the ring or through thenotch F therein into the bulb. In case the tip is not replaced until after the bulb is expanded a sufficient amount of air may enter through the nozzle; but it is desirable that a valve'should be arranged in the nipple for the inlet of air. As the inner end is contracted and the stem of the nozzle extends ICO into the contracted portion, it follows that if held in an upright position practically the entire contents of the bulb may be ejected.

It will thus be seen that a device is produced which is readily carried by cycle-riders, one which is conveniently operated and from which most of the material in the bulb may be' ejected without invertingr the device.

I am aware that flexible bulbs have been used in connection with nozzles which extend into or through the bulb, and therefore do not wish to be understood as claiming, broadly, such as my invention.

Having fully described my invention, what l claim as new, and desire to secure by Letters Patent, is

1. The herein-described sprayer com prising a flexible bulb having a contracted inner end, and an opening at the opposite end, an externally-threaded nipple secured in the said open end and formed with a central longitudinal opening, a nozzle having a stein extending through said nipple into the contracted portion of the bulb, a collar permanent-ly secured to said stein, and internally threaded for engagement with said nipple, whereby the inner end of the stein is positively located in the contracted portion of the bulb, substantially as described.

2. The hereindescribed sprayer,co1nprising a flexible bulb open at one end, a nipple secured in the said open end and formed with a central opening, the outer end of which is enlarged, the upper end of said nipple exteriorly threaded, a transverse hole in one side of said upper end, a flexible rubber ring within the enlarged upper end of said nipple, and a nozzle having a stem extending into said bulb and formed with a collar interiorly threaded for engagement with said nipple, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
