Description

July 27, 1965 s. KRAMER SPRAY MIST DISPENSING APPARATUS Filed June 25, 1963 I STANLEY KRAMER United States Patent 3,197,145 SPRAY MIST DISPENSWG APPARATUS Stanley Kramer, Cherry Hill, N.J., assignor to Salon Spray System, Inc., Philadelphia, Pa., a corporation of Pennsylvania Filed June 25, 1963, Ser. No. 299,423 8 Claims. (Cl. 239-415) In general, this invention relates to a new and improved spray mist dispensing apparatus and more particularly to a spray mist dispensing nozzle capable of directing a liquid spray without initial dripping or divergent scattering.

In the modern beauty salon, a hairdresser will spray a hair set mist on the customers coifiure to hold it in place. The spray is achieved by dispensing air through a nozzle and directing it at a continuously dispensed liquid so as to create a fine mist which is controlled by the hairdresser.

However, in the past, the liquid lotion for the hair spray would initially drip before becoming a mist. Additionally, since the lotion was also dispensed through a nozzle, the pressure from the air nozzle would cooperate with the pressure from the liquid or lotion nozzle to scatter the resultant spray-liquid droplet mixture in a direction not intended by the hairdresser.

Therefore, it is the general object of this invention to avoid and overcome the foregoing and other difiiculties of prior art practices by the provision of a new and better spray mist dispensing apparatus.

A further object is the provision of new and better spray mist dispensing apparatus which will automatically eliminate initial dripping or scattering from the air in liquid nozzles.

A still further object of this invention is the provision of a new and more simple spray mist dispensing apparatus which can be simply and easily operated and cleaned with little or no effort.

Another object of this invention is the provision of a more simple and better spray mist dispensing apparatus wherein the direction of spray is automatically determined by the direction of the air nozzle.

Other objects will appear hereinafter.

For the purpose of illustrating the invention, there is shown in the drawings a form which is presently preferred; it being understood, however, that this invention is not limited to the precise arrangements in instrumentalities shown.

FIGURE 2 is a cross sectional view of the apparatus of FIGURE 1 taken along lines 22.

FIGURE 3 is a cross sectional view of the apparatus of FIGURES 1 and 2 taken along lines 33 in FIG- URE 2.

FIGURE 4 is a cross sectional view of the apparatus of the present invention taken along lines 44 in FIG- URE 3.

FIGURE 5 is a cross sectional view of the apparatus of the present invention taken along lines 5-5 in FIG- URE 3. a

In FIGURE 1, the the spray mist dispensing apparatus of the present invention is generally designated by the numeral 10. The apparatus includes a main body 12 which is substantially rectangular. Extending outwardly from one face 13 of the main body 12 is a liquid nozzle extension 16. The liquid nozzle extension 16 supports a liquid dispensing nozzle 14 parallel to the face 13.

On the face 13 and in line with the liquid dispensing nozzle 14 is a suitable air dispensing nozzle 18. The air dispensing nozzle 18 is spaced from and perpendicular to ife the liquid dispensing nozzle 14 and in the same horizontal plane.

The liquid dispensing nozzle receives liquid such as a hair spray lotion through a suitable conduit 20 which shall be generally designated as a liquid supply means. The air nozzle 18 receives pressurized air through a suitable conduit 22 which shall be generally designated as a pressurized air supply means.

The

conduits

20 and 22 are removably secured to bushings 24 and 26 respectively so that the apparatus 10 can be utilized with other types of hair spray lotions in accordance with the desires of a customer.

The dispensing apparatus 10 includes an actuator 28 mounted above the main body 12 and supported by the air valve stem 32. The valve stem 32 is threadably engaged with the actuator '28. Additionally, a liquid valve stem 30 is provided which has a lost motion connection withthe actuator 28 by reason of an enlarged recess 34. The actuator 28 is spaced from the main body 12 by' the air valve stem 32 a distance greater than the space between the end of liquid valve stem 30 and the bottom of;

axial movement by a suitable O-ring 40. The air valve stem 32'is sealed for vertical movement in the bore 38 by O-ring 42. The bore 36 widens at its lower end to form a valve seat 43. An O-ring 44 on the valve stem 30' rests against the valve seat 43 in the closed position shownin FIGURE 3. The bore 38 widens at its lower end into a Valve seat 45 against which rests an O-ring- 46 connected to valve stem 32. The valve stem 32 is shown in its closed position in FIGURE 3.

The valve stems 30 and 32 are expanded to form

guide heads

48 and 50 respectively which will cooperate with.

the O-

rings

44 and 46 and

valve seats

43 and 45 to seal the

bores

36 and 38 when the actuater 28 is in the position shown in FIGURE 3.

The

guide portions

48 and 50 each have four outwardly extending

keys

52 and 54 respectively which maintain the

valve stems

30 and 32 in fixed alignment for move ment only in a vertical direction. The valve stems 3i) and 32 are biased to the closed position shown in FIG URE 3 by

suitable springs

56 and 58 placed between the

guide heads

48 and 50 and bushings 24 and 26 respectively. The liquid nozzle 14 is connected to the bore 36 between O-

ring

40 and 44 by a passage 64 extending from bore 36 into extension 16 and terminating at a needle valve 66 within the extension 16. -The needle valve 66 controls the flow of liquid through passage .64 to a passage 68 leading to liquid nozzle 14.

The pressurized air nozzle 18 receives air from bore 38 intermediate O-

rings

42 and 46 through a suitable passageway 70 extending between nozzle 18 and bore 38.

In operation, the conduit 20 supplies hair set lotion through the bushing 24 behind the O-ring 44. Similarly, pressurized air is fed through conduit 22 and bushing 26 behind O-ring 46. a

The hairdresser need only press downwardly on actuator 28 to directly receive a hair spray mist without dripping or scattering. Pressing of actuator 28 moves valve stem 32 downwardly and removes O-ring 46 from valve seat 45. Air under pressure is then passed through bore 38 into passageway 70 andout nozzle 18.

The valve stem 30 is not immediately actuated by downward movement of actuator 28 because of recess 34.

The recess 34 provides a lost motion connection between.

the actuator 28 and the valve stem 30. After pressurized air is transmitted through nozzle 18, the continued downward movement of actuater 28 moves valve stem downwardly unseating O-ring 44 from valve seat 43.

Liquid hair set lotion then passes upward through bore 36 and passageway 64 into passageway 68 in accordance with the setting of needle valve 66. This liquid then passes out of liquid nozzle 14 and in a direction per-. pendicular to the flow of pressurized air from air nozzle 18. Pressurized air having been previously transmitted through nozzle 18, instantly forms a mist of the liquid dispensed through nozzle 14. The'liquid will not drip from nozzle 14 as the pressurized air will already be passing immediately in front of it. Also, the pressure from the liquid nozzle will not have an opportunity to cause scattering of the resultant mist as no liquid droplets will be formed and the resultant direction of the fiow of mist will be determined by the air spray nozzle 18.

There are times, when solid material may build up within the liquid flow path causing clogging of the spray mist dispensing apparatus. .In order to clean the path 68 and the nozzle 14, it is only necessary to remove the needle valve 66 and push a wire through the path 68 till it is cleaned. Further, the nozzle '14 is screw threaded to the extension 16 and can be separately removed if necessary.

- To clean the pathr64, a second path 72 has been pro vided in the main body 12 in line with the path 64 and extending from a'face 73 opposite from face 13 of main body 12. The path 72 has one end closed by a suitable plug hole screw 74. Additionally, a'hole. 76 has been 76 and path 64, thepath '64 can befunclogged without the necessity, of removing the valve stem. The hole 76 does not in any way interfere with the operation of the dispensing apparatus.

Theair passage 70 can be easily cleaned by removing the air nozzle 18 which is screw threaded into the main body 12.

Thevalve stems can be removed by removing the bushings 24 and 26 which are screw threadedly secured into the main body 12. Once the valve stem 30 has been removed, the actuator 28 can be unscrewed from the valve stem 32 thus permitting the stem 32 to be removed through the openingprovided by the removal of bushing 26. In this way, the entire dispensing apparatus can be simply and easily cleaned when necessary.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification as indicating the scope of the invention.
