The liquid passages in these nozzles Fig. 1 is an elevation of one form of the immay be of various diameters, and are usually conproved implement, loolnng toward the liquid flow siderably smaller than the passage 15 in the supcontrol lever and toward the end of the liquid port 10.

)0 supply' reservoir; The end of the cylinder or reservoir 12 which Fig. 2 is a central longitudinal section through communicates with the passage 15 of the supthe implement and supply reservoir of Fig. 1, the port 10, may be provided with a removable closure section being taken along the line 22 of 1; 27 for filling the reservoir displacement chamber Fig. 3 is an enlarged longitudinal section with liquid paint 14 or the like. The opposite 55 through the flow control portion of the impleend of the reservoir 12 is provided with a removable cap 28 through which the plunger rod 29 extends, and a helical-spiral compression spring surrounds the rod 29 and coacts with the cap 28 and plunger 13. The plunger 13 is furthermore provided with a cup-shaped packing 31 which is held in place by a retainer 32 and nut 33, and prevents paint 14 from escaping past the plunger 13. When the reservoir 12 is being filled with paint 14, the plunger 13 is withdrawn by hand with the aid of the rod 29, to compress the spring 30, and this spring 30 subsequently functions to urge the plunger 13 against the paint 14 confined within the reservoir, upon release of the rod 29. If the control valve 16 is then opened, the spring 30 coacting with the plunger 13 will force paint from the reservoir 12 through the passage 15 and nozzle 11 until the supply is entirely deleted or exhausted.

The mode of utilizing the implement shown in Figs. 1 to 4 inclusive, should be clearly apparent from the foregoing description. When the reservoir 12 has been properly charged with paint 14 and the closure 27 has been applied, the implement may be manipulated like an ordinary pencil or brush to produce lines of paint flowing from the nozzle 11. A finger of the operator may be applied to the control lever 19 to regulate the flow of paint, and the set screw 22 serves to vary the degree of opening of the passage 15. As the paint 14 is discharged from the reservoir 12 by the spring 30, the plunger 13 gradually approaches the closure 27 until the paint supply is entirely exhausted. The various parts may be readily removed for inspection and cleaning, by merely releasing the cap 28 and plug 18, and the implement is so compact that it can be carried in an ordinary pocket.

Referring specifically to the embodiment of the invention shown in Fig. 5, the implement again comprises a support 40, a nozzle 11 secured to one end of the support by means of a carrier 26 and lock nut 25, a reservoir 42 connected to the opposite end of the support by means of a hose 41, and a plunger 43 movable within the reservoir 42 by means of a helical-spiral spring 44. The

support 40 difiers from the support 10 previously described, only in that it is flexibly connected to the supply reservoir 42 by the hose 41, instead of being rigidly attached to the reservoir. The

support 40 is provided with a control valve 16 identical with that previously described, and the nozzle 11 and its attachment are also the same as those heretofore described.

The upper cap 45 of the receiver 42 is provided with an eye 46 for suspending the same from the belt of an operator or from a trolley, and this cap 45 is moreover provided with a closure 27 for supplying paint 14 to the reservoir 42. The lower cap 47 against which the spring 44 reacts, has a central bushing 48 with which the hollow plunger rod 49 coacts. The plunger 43 as in the case previously described, is provided with a cupshaped packing 31 held in place by a retainer 32 and a nut 33, and the plunger rod 49 has a through passage 50 therein, the upper end of which communicates with the paint supply confined within the reservoir 42, and the lower end of which communicates with the hose 41 through a nipple 51 attached to the lower end of the plunger 49.

The implement of Fig. 5 enables the storage of a greater supply of paint 14, than is possible with the pocket implement previously described, by virtue of the fact that a reservoir 42 of any desired capacity may be utilized. The hose 41 may be of any desired length and is sufliciently flexible so as not to interfere with the free movement of the support 40 and nozzle 11 during normal use of the implement. In the implement of Fig. 5, the rate of flow of the paint 14 from the reservoir 42 will be substantially constant because of the vertical disposition of the reservoir, and as the paint supply is diminished, the spring 44 will expand and the difference in expansive effort of the spring as its limit of expansion is reached, will be compensated for by the diminishing weight of the paint supply.

From the foregoing description it will be apparent that the present improvement provides a marking implement which is extremely simple and compact in construction, which is highly efficient in operation, and all parts of which are readily accessible for cleaning. The delivery of paint from the supply reservoir may be readily and accurately controlled by manipulating the control lever 19 and by adjusting the set screw 22, and the nozzle 11 may be conveniently replaced by any other suitable type of nozzle or brush. The supply of paint 14 may be readily replenished with the aid of the plunger rod, and the spring coacting with the plunger effectively maintains the liquid hermetically sealed and in constant readiness of use.

It should be understood that it is not desired to limit the invention to the exact details of construction herein shown and described, for various modifications within the scope of the claims may occur to persons skilled in the art.
