SPRAY GUN GASKET SECURING DEVICE Filed Jan. 28, 1959 E4 M0? [B /v.
INVENTOR BY 1 I I I ATTORNEYS.
United States Patent 2,987,226 SPRAY GUN GASKET SECURING DEVICE Elmer F. Bane, 'Box 322, Edgewater, Fla. Filed Jan. 28, 1959, Ser. No. 789,728 1 Claim. (Cl. 222-464) By way of explanation, it might be stated that the covers of conventional paint spray guns used in spraying automobiles, are sealed by rubber gaskets positioned between the covers and cups or containers of the spray guns, which gaskets frequently adhere to the paint cups or containers or pull free of the cups or containers when the covers are removed.
It is therefore the primary object of the present invention to provide means whereby the sealing gasket used in sealing the covers of spray guns to the receptacles, are securely held in place against the covers so that when the covers are removed, the gaskets will be retained in their proper positions on the covers against accidental displacement.
Another important object of the invention is to provide a gasket securing device of this character which may be readily and easily positioned over the stems of spray guns and held in position by nuts which are threaded on the discharge ends of the spray gun, eliminating the necessity of making extensive alterations in mounting the attachment.
With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
In the drawings:
FIGURE 1 is a bottom plan view of a spray gun cover equipped with a gasket securing disk, forming the subject matter of the present invention.
FIGURE 2 is a fragmental sectional view taken approximately on line 22 of FIGURE 1.
FIGURE 3 is a plan view of the gasket retaining disk.
FIGURE 4 is a fragmental plan view of the flanged end of the spray gun cup.
Referring to the drawing in detail, the reference character 5 indicates a paint spray gun cup or container which is provided with the usual outwardly extended annular flange 6 under which the hooks 7 engage securing a cover 8 to the cup or container 5. The flange 6 is provided with slots 5' which permits the hooks 7 to be positioned under said flange when the cover is positioned to close the container 5.
The siphon stem 9 extends through the cover 8 of the cup or container 5 and has its upper end threaded as at 10.
All of the above is a conventional spray gun construction, and does not per se constitute the present invention.
The reference character 11 indicates the conventional sealing gasket disposed between the cover 8 and flange 6 of the spray gun cup or container for maintaining an airtight connection between the cover and container to insure the proper operation of the spray gun.
iatented June 6, 1961 The metal disk 12 forming the subject matter of the present invention, is concavo convex in construction and is of a diameter to fit within the cup or container 5 with its edge in contact with the gasket 11, as better shown by FIGURE 2 of the drawing.
The disk 12 is provided with an opening so that it may be fitted over the siphon stem 9 and positioned in contact with the nut 13 positioned on the siphon stem 9 at a point in spaced relation with the discharge end 14 of the siphon stern.
A nut 16 is mounted on the threaded portion of the siphon stem 9 above the cover 8 and when properly positioned, sets up a clamping action with the nut 13 to force the disk 12 into close engagement with the gasket 11, securing the gasket to the cover 8 so that when the cover is removed, the gasket which usually adheres to the upper edge of the spray gun cup or container 5, is broken loose from the cup or container 5 and removed with the cover 8, the gasket being maintained in its proper position so that it may be readily assembled on the open end of the spray gun cup or container 5 and eliminating any possibility of the gasket becoming accidentially displaced when the cover is removed.
From the foregoing it will be seen that due to the construction shown and described, I have provided means whereby the usual sealing gasket of the cover of a spray gun, is securely held to the cover of the cup or container at all times.
Having thus described the invention, what is claimed A spray gun cup having a wide outwardly extended annular flange disposed at the open end thereof, a sealing gasket resting on said flange, a portion of said sealing gasket extending inwardly beyond the wall surface of said cup, a siphon stem having a threaded upper end disposed centrally of said cup, a spray nozzle on the threaded end of said siphon stem, extending above said cup, a stop nut mounted on said threaded portion of said stem below said spray nozzle, a concavo convex disk having an axially disposed opening, positioned on said siphon stem, resting on said stop nut with concave surface of said disk disposed upwardly, the upper edge of said disk bearing against said gasket, a flat cover fitted over the open end of said cup, having an opening aligning with the opening of said concavo convex disk through which said threaded end of said siphon stem extends, a nut mounted on the threaded end of said siphon tube above said flat cover for effecting vertical movement of said siphon stem and said concavo convex disk, compressing said disk, forcing said disk into sealed engagement with said gasket and cover.
