SPRAYER.

Specification of Letters Patent.

Patented June 1a, 1212 Application filed October 25, 1911. Serial No. 656,592.

To all whom it may concern.-

Be it known that I, Jo nt OvERBEKn, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and useful Improvements in Sprayers, of which the following is a specification.

This invention relates to improvements in sprayers, and more especially in that type of sprayer is ej ected through the nozzle by the action of a piston movable in the cylindrical body of the device.

- It has further reference to the type of sprayer in which provision is made for mix ing a material contained in the cylinder with a stream of fluid and subsequently ejecting the mixture.

Briefly described, the invention compres hends primarily a self-contained spraying device within the cylinder or body portion of which the discharge piston is arranged. The aforesaid cylinder is adapted to contain a powdered substance which is mixed with a stream of fluid and ejected through the spraying nozzle, the cylinder being so constructed that the in-coming. fluid is divided into two streams, one of which mixes with the powder, as above stated, while the other is directed against the piston and serves to produce the effective movement thereof. Thus the fluid is utilized for two distinct purposes, both as amotive agent for actuating the piston and as a vehicle for the powder.

An embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a longitudinal sectional view of the improved sprayer in its simplest form; Fig. 2 is a top plan view; Fig. 3 is a bottom plan view, with the nozzle omitted; Fig. 4 is a side elevation, with parts in sec- Fig. -5 is a transverse section on the line 5-5 of Fig. (1; and Fig. 6 is a bottom plan View of Fig. l, likewise with the nozzle omitted.

In said drawings, 1 indicatesthe cylindrical body of the device, 2 and 3 the upper and lower caps'or heads thereof, and 4 the spraying nozzle. Said caps are provided, respectively, with axially-located collars 5 and 6, the former of which is internally'threaded, so as to permit the device to be attached to a hose, hydrant, faucet, or other suitable source of water supply. The collar 6 on the wherein the material to be sprayedlower cap is threaded both externally and internally, lts bore receiving a threaded sleeve 7 whose inner end projects into the interior of the cylinder and is provided with apertures 8, hereinafter referred to; the nozzle 4., which may be of any preferred or conventlonal type, is attached to this collar by means of its internally-threaded enlarged inner end 9 which receives said collar. Both caps are preferably formed with internallythreaded peripheral flanges, by means whereof they maybe attached to and'detached from the endsof the cylinder, though the upper cap may, if desired, be permanently secured to said cylinder by brazing or otherwise.

To permit the entry of water into the. cylinder, that portion of the upper cap which is inclosed by collar 5 is formed with a central aperture 10 and with a series of smaller apertures 11 arranged therearound. The first-mentioned aperture receives one end of a pipe 12 whose other end projects into sleeve 7 the apertures 8 in the inner end of said sleeve (which are preferably in the form of longitudinal slots) extending outwardly beyond the terminal of said pipe, as shown.

Within the cylinder works a piston 13 of any desired type, said piston sliding upon pipe 12, which latter is introduced through an axial opening formed in the hub portion tering the cylinder behind it through the apertures 11. This movement of the piston serves to discharge the powdered contents of the cylinder through apertures 8 into sleeve 7, where it mixes with the water flowing through pipe 12, themixture then being discharged through the nozzle in the form of a spray, as will be understood. Any suitable means may be utilized for regulating-the flow of water into and through pipe 12, a screw 14, which is fitted in a radial passage formed through collar 5, being shown (in dotted lines) in Fig. 2.

In charging the cylinder with the powdered material, lead acetate, for instance, it is necessary to remove cap 3, and then force of the piston. The piston is moved toward the lowercap by the force of the water enpiston 13 backward'toward cap 2 by means W pv . ing nozzle.

- been removed, and said sleeve not be formed with a kerf at the point inas shown in Figs. 4:, 5 and size and shape, a cutolf device, 6. Such device preferably comprises a rotatable disk or plate 16 which rests flat against cap 3 and is formed with an opening 17 of the same size and shape as opening 15, the movement ofthe plate being effected by means of a opening 15 of the proper which is normally closed by headed stud 18, or the like, that is attached thereto and projects through and travels in, anuircuate slot 19 formed .in the cap.-

At its center, said plate is provided with a circular opening 20, through which the upper end of sleeve 7 projects, the formation of this opening preventing the plate from interferingwith the How of the powdered material into apertures 8. It will heapparent, therefore, from the foregoing, that when the cut-off plate is rotated in 1 the. proper direction to bring opening 17. into through the cylinder in two, separate,

streams, one stream passing directly through pipe 12, which it enters by way of aperture 10, while the other stream enters through the .series of apertures 11 and serves to operate the piston, whereupon the powdered material contained in the cylinder is gradually forced through apertures 8 into sleeve 7 where it mixes with the first stream and is carried by the latter through the spray- Sleeve 7 may be adjusted 1n and. withdrawn from collar 6 by means of any suitable tool, not shown, which is inserted in its lower end, after nozzle 4: has may or may dicated, to facilitate the engagement of the tool end therewith. This kerf is illustrated in Fig. -fl b11t it is omitted in Fig. 1:

The invention may be put to a number of different uses, as, for instance, in spraying trees, plants and'shrubs, applying paint or other material to walls and the like, and for fire extinguishing and disinfecting purposes. v

I claim as my invention:' 1. A sprayer comprising a chargeable cylinder having each of its endmembers pro vided with a collar, one of Which'collars is adapted for connection with a source of fluid supply, the portion of the end mem-- ber inclosed by that collar being formed with a central aperture,'and with aseries of apertures arranged therearound; aspraying nozzle connected with the other collar;

a sleeve fitted in the second-named collar and having its inner end projecting into the interiorof the cylinder and formed with apertures; a pipe fitted at one end in said central aperture for conducting the fluid passing therethrough into the sleeve, and at the other end fitted in said sleeve, the apertures .in the sleeve extending outwardly beyond the terminal of said pipe; and a piston slidable upon said ipe and operated by the fluid admitted bac of it through said series of apertures, for forcing the contents of the cylinder through the sleeve apertures into said sleeve to mix therein with the fluid passing thereinto through said pipe.

2. A sprayer comprising a chargeable cylinderprovided at one end with an outlet, and a sprayer nozzle connected thereto; a sleeve fitted in said outlet, said sleeve having its inner end projecting into the inlterior of the cylinder and formed with :apertures; a fluid supply pipe arranged within said cylinder and having its outlet end fitted in said sleeve, the apertures in the sleeve extending outwardly beyond the terminal of the pipe; and a piston shdable upon said pipefor forcing the contents of the cylinder through said apertures into the sleeve, to mix in said sleeve with the fluid passing thereinto through the pipe.

In testimony whereof I have hereunto set my hand in presence of two subscribing W1tnesses.

JOHN OVERBEKE.
