ACTUATOR-ADAPTER FOR SPRAY CAN Filed July 30, 1962 5 /6 7 /0 a v hr 9 3 i W I ah @fl INVENTOR United States Patent 3,159,319 ACTUATQR-ADAPTER FOR SPRAY CAN Roy Parish, 285? Thornhiil Drive, Mobile, Ala. Filed July 30, 1952, gar. No. 214,451 1 Claim. (Cl. 222394) This invention relates to the pressurized container as and wherein heavy material products such as paint and lacquers and the like, are sealed within the container in a fluid pressure atmosphere and released therefrom upon depressing valve element, and more particularly to an improved cam lever control member and removable adapter base member for the container serving as a carrier for the lever member.
It is an object of this invention to provide a device which can be clamped to the rim of a spray can and which has a cam lever for reciprocating the push button of the can and a cam member disposed between the cam lever and the push button to provide a line-cam-tangential contact between the lever and the intervening member, and to maintain an eflicient cam contact between the intervening member and the push button, for all positions of the push button.
Another object of the invention is the provision of an adjustment stop screw on the lever, with a lock sleeve surrounding the screw whereby the amount of downward movement of the lever (and, consequently, the amount of swing of the intermediate cam member and the extent of reciprocation of the push button) can be adjusted, whereby the flow of discharge from the spray can can be regulated and controlled.
With these and other objects in view, this invention involves certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.
For a more complete understanding of my invention reference is to be had to the following description and accompanying drawings, in which:
FIGURE 1 is a side elevation of the device attached to the related container with a push button spray valve, the container and push button being shown in phantom;
FIGURE 2 shows a side elevation, with a portion cut away to show the lever and intermediate cam member journaled on the pivot shaft; and
FIGURE 3 shows a top plan view of the device.
The drawings show a device adapted to be attached to the outer rim of an aerosol can and includes an actuator for the push button on the stem of the conventional reciprocable valve of the can. The device consists of a cup-shaped base member 5, including a base wall, centrally apertured at 14, to accommodate the can valve stem and a downwardly extending cylindrical flange 5a to surroundingly embrace the rim of the can. The cup-shaped member is interrupted at one side, both in the base wall and in the flange, by a slot extending continuously from the bottom of the flange to the base wall and, in the base wall, from the outer periphery to the aperture 14, as indicated at 15, FIG. 3. Two lugs, 12 and 13, extend radially outward from the extremity in the base wall and are separated by an extension of the slot in the base wall, formed by the space between the lugs. The lugs are transversely bored and threaded to accommodate bolt 3. The bolt, when threaded into said apertures in said lug, and when the flange surrounds the rim of the can, as shown in FIG. 1, receives a nut 4, by means of which the flange is tightened, and thus secured on the container rim.
Two brackets 6 extend upward from the base member in a direction parallel to the axis of the can. They are spaced symmetrically equal distances from said axis, the distance between them being greater than the outer diameter of the button on the aerosol valve stem. The brackets are arcuately contoured and terminate in re- 3,159,3l9 Patented Dec. 1, 1964 duced ends forwardly of the base wall aperture and the push button, as shown in FIGS. 1 and 2 of the drawings. Said upper ends are apertured to receive bearing shaft 8 which provides the fulcrum or pivot for the pivoted end of the button contacting cam member 16, as well as for the pivoted end of the actuating lever 11. The pivoted end of the cam member 16 is centrally journaled on the shaft 8, while the pivoted end of the actuator lever is forked into two branches, which flank the sides of the pivoted end of the cam member 16 so that, with both the elements 11 and 16 thus pivoted on the same shaft 8, the under surface of the lever 11 contacts the upper surface of the free end of the cam member 16 which is looped, at both its ends, to provide the pivot on the shaft 8 at the front end, and at its rear end, to provide a line cam contact between the member 16 and the under surface of the lever 11. The intermediate portion of the element 16 is sloped to contact the upper surface of the button. Both elements are contoured as shown in FIGS. 1 and 2 and are dimensioned to be located within the space between the brackets 6, as shown in FIG. 3. The lever 11 is apertured, at a point opposite the outer edge of the base member, to receive the adjustable stop member 9, which is threa'dedly engaged in said aperture, and adjusted by turning the screw head. The knurled sleeve 10, which surrounds the screw, limits the inward travel of the screw.
It is believed that the operation of the device is clear from the foregoing description. The device is clamped on the rim of an aerosol can by disposing the flange 5a around the rim and tightening the nut 4 on the bolt 3. The amount of reciprocation of the lever 11, and hence of the reciprocation of the valve button, is adjusted by means of the screw 9, as aforesaid, to produce the desired discharge of spray.
It will be further appreciated that the cam lever member provides for a force multiplication which enables the cam valve to be opened with a manual pressure which is only a fraction of that which would be required were the valve being opened by manual force applied directly downwardly to the same.
Economy of operation is significant, as the usable material in a spray container is exceptionally low, considering the fact that the contents of container contains approximately forty percent propellant agent. The natural tendency of operating a spray container is depressing the valve element fullly downwardly due to the resistance of spring in the valve element, resulting in an over-spray condition and producing a heavy wide spray density pattern, in which it is considered unnecessary and wasteful. To operate the valve element in any other position that would correct the difliculty and obtain a narrow light spray density pattern is extremely diflicult to accomplish. The device overcomes this condition in its regulation of flow quantity by the cam lever member travel speed, in which any intermediary position of the cam lever member becomes available in a non-critical movement, and once obtained it can be maintained by adjustment of stop screw provided on the cam lever member.
I claim:

(a) a downwardly facing cup-shaped member, including a base wall, centrally apertured to accomodate said stern and a downwardly extending cylindrical flange, dimensioned to surroundingly engage said rim, a radial slot extending from the central aperture in the base wall to its outer extremity on one side of said aperture, and continuing downward to the lower edge of the flange,
(b) a pair of lugs extending radially outward from the outer end of the slot, spaced apartso as to provide between them a continuation of the slot in the base Wall, the lugs being transversely apertured and threaded to receive a clamping bolt, by which the flange is adapted to beclamped on said rim, (0) two brackets,*e7 tending upwardly from said based walls, spaced symmetrically on both sides of the slot,
a distance sufiicient to accommodate, with clearance, Y
acam surface, theintermediate portion being slanted to contact the top of the button, I 1

located on said lever so as to engage the end of the base wall opposite to the end with the radial slot, when the lever arm is pivoted downward to reciprocate the valve, so as to limit the'extent of said rcciprocation. I
