Jan. 2, 1940. k. BERNHARDT SPRAYER Filed MarGh l, 1937' Patented Ja z; 1940 I I L J "'SPRAYER 1 f I .Rudolph Bernhardt; ChicagoQIlL Applicationl March 1, 1937, Serial No. 128,441 I com e 01.299417) This invention relates to sprayers which may be use'dfo'r variousfpurposes but which are particularly intended for spraying-lotions or emulsions such as wave sets or the like. I These lotions are 5 usually of a-mucilaginous or slippery character. Consequently when applying the same to the hair the lotion gets on the hands of the operator and makes it diflicult tohandle the container holding themateriah. In accordance with 'thepresent invention I provide 'a' container or bottlepreierably having a relatively long neck and a sprayer having a handleportion arranged to cooperate with the bottle so 'that'the device may be conveniently held and manipulated by one hand.

Other objects of the invention are to provide a sprayer includingv a container and havinga handle portion for engagement with one finger of the operator and the spray nozzle heldin adjustedposition so that it may be actuated by the thumb;

I! and to provide such other novel features and advantages as will appear morefully from'the following description. p h

In the accompanying drawing illustrating this invention,

' of Figure 2."

In the particular form of sprayer shown in this drawing, 5 is the bottle or container having a neck portion 6 preferably of sufiicient length so that it v may be convenientlyengaged by several fingers of U the operator. As shownin Figure v1, the bottle has a cap I of the threaded type or other suitable type. The spray'pump has a cylinder or'tubular portion 8 with a downwardly extending intake pipe 9 and has a ring or flange Hi preferably I 40 formed integrally therewith, and a threaded upper end II which extends outthrough a hole in the top of the cap. A stiffening washeror disc I2 is preferably inserted between the flange or bead In and. the cap.

of the cylinder and has an axial projection with a hole M of hexagonal or other suitable shape for receiving the hollowpiston rod l5 which is slidably mounted therein. The piston rod is con- 5 nected with a piston l6 which fits closely within the cylinder 8. raised position by a spring I 'Lthe lower end of which rests on the end of the cylinder and the upper end engaging with a washer l8 fitting against the lower end of thepiston. This washer The piston is normally held in I has a hole H! which" serves as a'valve seat'fora ball 20, thus providing a check valve for the pump:

A relatively light spring Z'i'is also provided for taking upany jar due to the quick outward move ment of the piston unde'rtlrie influenceofth'e spring II. The spring 2! is "interposed between the upper end of the piston and the nut was shown in Figure 3. The piston "rod: l5 has a spray nozzle or Ethe'like 2 2 secured-to theupper end thereof and ar'ranged at appr xim'atuywig'ht angles thereto. This nozzle portion has a groove 23in alignment with the nozzle discharge'for receiving the thumb of the operator, which is used foractuatingthe sprayer. A handle 24 has a hole at one end for receiving the threaded end I l of the cylinder and is provided with an annular bead or ridgez25 for stiffening the same and for receiving a strengthening Washer 25 which is interposed between the end of the handle and the nut or cap nut l3, the. arrangement being such that when the nut is tightened the handlemay be held securely in any adjusted position circumferentially with respect to the spray nozzle. The handle may also be provided with additional-ribs 21 for stiffening the same and terminates in a downwardly curved end portion 28 which fits over the index finger of the operator as shown in Figure 1.

When an operator uses the sprayer the neck portion of the bottle is grasped by the fingers; for p v instance of the right hand and the handle fits against the index finger as shown, which brings the thumb in alignment with the groove 23 so that the spray may be positively directed in the desired direction. By means of this arrangement the container or sprayer may be. securely held even if the-hand becomes slippery due to contact with the lotion. If the operator is left-handed the handle may be adjusted relatively to the spray nozzle as shown in dotted lines in Figure 2, by

loosening the nut and swinging the handle around and again tightening the nut to hold the parts in such adjusted position.

Having thu'sdescribed'my v invention, What -I v .'claimis: A nut l3 engages with'the threaded upper end relatively long neck adapted to be engaged by the of the discharge tubein'the cap, and a handle extending outwardly from the cap at substan-,

.1. The combination with a receptacle having a 45 tially right angles to theoutlet of the discharge nozzle and adapted to engage with the'finger of the operators hand while grasping the bottle, the

discharge nozzle being. positioned to be engaged by the thumb of the operator's hand while porting the bottle.

2. The combination with a bottle having an elongated neck providing a hand hold, of a cap for the bottle, a spray pump mounted in thecap and having a reciprocable spring actuated dison the fingers while the thumb may be used'for reciprocating the discharge pipev whereby. the spray may be discharged in a predetermined direction.

3. The combination with a bottle having aicap, of a pumpcylinder having a threaded end extending outwardly through a hole in the cap, an annular abutment on the cylinder on the inside of the cap, a nut engaging with the threaded end of the cylinder and having an axial projection With'a non-circular hole therethrough, a springpressed piston mounted in the cylinder, a reciprocable hollow piston rod extending outwardly from the piston through the hole in the projection, the periphery thereof conforming to the shape of vthe hole whereby "the rod is positively prevented from suprotating, a discharge nozzle at the end of the rod extending at right angles thereto and having a groove in the top, and a handle'having a hole for receiving the threaded end of the cylinder and extending laterally from the cap, the handle being interposed between the nut and cap and held in adjustedposition by tightening the nut.

4. The combination with a bottle having a cap,

of a pump cylinder extending downwardly from the cap and having a threadedportion extended upwardly through the holein the-"cap, said cylin der having an integrally formed abutment, a

.. washer interposed between the abutment and the inside of the cap, a handle having a hole for.re- 'cei'ving the threaded end of thecylinder and having an annular bead around the hole, a washer fitting within the bead, a cap'nut engaging with the threaded end of-"the cylinder and coacting with the abutment to hold the parts in adjusted position; a'piston in the cylinder, a spring-tending to hold the piston in raised posit-1cm 'a-shock absorbing spring between :thejpistonand theycap nut, said piston having'a hollow rod' of angular periphery extending outwardly through a hole in vent turning of the same, a discharge nozzle hav ing adischarge portion extending at righ-tangles for receiving a thumb.
