A TTO NEYJ'.
Patented Apr. 15, 1930 UNITED STATES FREDERICK PA'LEN'Iy OFFICE R. JEFFERYS, OF CLEVELAND, OHIO, ASSIGNOR T THE AETNA RUBBER COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO Application led September 1', 1928. Seriallo. 803,477.
6 taining temperature and the present construction allows such fit to be obtained regardless of slight variation in size of opening or in shape. In addition, the structure provides a light moisture proof unit which is 10 well insulated. To the accomplishment of Y of the usual construction with the circularthe foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.
Theannexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.
In said annexed drawing Fig. 1 is a vertical sectional view on the line 2-2 of Fig. 2; and Fig. 2 is a fragmentary top plan view of the cover.
As illustrated, the cover l is shown in position in the opening 2 of a cover board 3 of an ice cream cabinet. This cover board is opening 2 having a substantially vertical side and rounded slightly at the upper edge. The cover proper consists of a ring 5 having a vertical bottom portion 6, an upwardl inclined section'? with a horizontal top ange 8, a bottom plate 9 is mounted on the ring to bl ft tightly over the vertical section 6. A cork or other insulating disk member 10 is mountedwithin the ring which it fits and over the top'is a second plate 11 which extends out to nearly the edge of the flange 8. This top plate is secured in position by a knob or handle 12 which is interiorly threaded to receive the threaded end of a bolt 13 which passes through suitable apertures in the two plates and disk 10.
The ring 5'is formed of rubber, the bottom portion including the straight portion 6 and the greater part of the incllned portion 7 being formed of hard rubber while the upper part of the ring including the flange 8 and a small portion of the inclined portion being formed of soft rubber, the two parts being formed into an integral unit by the use of proper hard and soft rubber compounds in the mold when being formed. At the line of division between the hard and soft rubber along the'inelined surface, the diameter of the ring is less than the normal diameterof the hole in the cover board of the cabinet and suiiiciently less so that the cover will easily enter until the soft rubber portion 20 of the inclined surface will en age with theboard. The diameter at theange is such that the cover has a tight fit and the soft rubber has sufficient resiliency so as to provide for variations in size of opening in the cover board and to allow the cover to be sealed with the flange resting. tightly against the top surface of the cover oard, thus insuring a'seal and reducing the heat loss as far as possible. i
B `using soft rubber, the cover may be ma e large enough so as to require a slight amount of force to fully seat it in position and this without danger of breakage of the ring as the hard rubber portion is suiiiciently small to fit easily within the cover board aperture. The hard rubber portion provides a ring of fixed diameter to which the bottom plate may be securely attached and a ring which will not distort when the top plate is clamped into position. This construction eliminates any necessity for gaskets or other removable means for sealing the opening and is simple and easy to manufacture and assem- Other modes of applying the principle of the invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.
I therefore particularly point out and distinctly claim as my invention 1. In a closure for ice cream cabinets, the combination of a disc sha ed member, an outside supporting ring o hard lrubber surrounding said disc, and an inte ally formed soft rubber cone shaped portion of larger diameter at the u per portion of said ring, and a soft rubber nge at the top of said ring extending outwardly from said cone shaped portion.
2. In a closure for ice cream cabinets, the combination of a disc sha ed member, an outside supportin ring o hard rubber surrounding said isc, said ring having a cylindrical portion near the bottom, a cone shaped portion of larger diameter thereabove and an outwardly extending horizontal flange at la the top, said flange and the upper part of said cone shaped portion being formed of soft rubber, and the balance of said ring being formed of hard rubber integrally united to the soft rubber.
15 3. In a closure for ice cream cabinets, the combination of a disc sha d member, an out` side supporting ring o hard rubber surrounding said disc, said rin having a cylindrical portion near the ottom, a cone 20 shaped portion of larger diameter thereabove and an outwardly extending horizontal flange at -the top, said flange and the upper part of said cone shaped portion being formed of soft rubber, and the balance of said ring 28 being formed of hard rubber integrally united to the soft rubber, a bottom plate for said closure surroundin said cylindrical portion, a top plate for sai closure engaging the top of said ring, and means to clamp said plates $0 to said ring.
Signed b me this 29th day of August, 1928. F EDERICK R. JEFFERYS.
