srnme-Unenn CLOSURE.
Application filed December a, 1919. Serial a... 343,245.
To all whom it may concern:
Be it known that I, ADAM W. KAUFMAN,
a citizen of the United States, and resident of Milwaukee, in the county ofMilwaukee and State of Wisconsin, have invented certain new and useful Improvements in Spring-Urged Closures; and Ido hereby declare that the following is a full, clear, and exact description thereof..
My invention relates to new and useful improvements in closure devices wherein the closure member is resiliently held in its open and closed positions, and the invention relates more particularly to the provision of a closure device for the oil aperture of the timer casing of an automobile structure.
It is in general the object of my invention to simplify and otherwise improve the structure, cheapen production and mincrease the efficiency and durability of closure devices of this character.
It is more particularly my object to pro- A vide a closure device ofthis character includin a pintle arra ngement, the efficiency of which is affected to a minimum degree by'the wear incidental tolong continued use of the device and wherein a positive resilient holding of the closure member selectively'in either closed or ,open position is'assured at all times.
A'further object resides in, the rprovisijonofa closure device for the oil aperture ofa timer casin which is movable in open position to full" exposethe a erture andthus most conveniently permit t e application of oil throu h the aperture. i
A furt h provide a'stamping plate member which is arranged to receive a disclosure for an oil a erture, a spring for controlling the. disc osure, and an arm portionjto which the spring is attached, the assembled 'stampings being adapted to besecured to the cap portion oi.v a timer casing as shown, it being understood that the arm extension of the stamping plate is also united for the purpose of swinging the timer.
vantages in view, whichwill be apparent as the description proceeds, my IIIVQIltlOIl resides in the novel features of construction,
er object of the invention isto' combination and arrangement of the parts as hereinafter describedand defined by the appended claims.
In the accompanying drawings:
Figure 1 is'a sectional view through my improved closure device and a portion of an engine timer casing with which the device is associated, the closure member being shown in closing position.
Figure 2 is a view similar to Figure 1, with the closure member disposed in open position.
A Figure 3 is a detail plan view of the base plate of the closure disposed.
Figure 4 is a plan view of the closure member, and
Figure 5 is aplan view of the spring employed for hold ng the closure member in open orclosed position. i
Referring'now more particularlyto the drawin s, 5 designatesaportion of the usual rotatab e casing member for the timer of an internaljcombustion engine, said casing beingprovided inits inclined intermediate portion with an oil inletopening 6. A plate 7 constitutingthe base member of the closure device is securedby rivets ,8 to the inclined portion of'the casing and said plate is provided with an aperture'9 registering with and slightly larger than the aperture 6, one end oi; the plate 7 being bent to form an armprojecting laterally from the casing, said arm'being apertured and carrying a thimble 10 adapted to recei ve a rod for shifting the casing tejadvapc'e or retard the spark of the engine. A common axial plane passes through the apertures in the plate 7 centrally between the rivets 8. The plate 6 is thickened aroundits aperture 9 to provide a closure-seat. The closure member com- A t I I duced fbearing extensions 14 constituting With the above and other objects and admajor'portion of the plate to extend into the recess 12 when the disk is seated in closing position. The heel extension is also provided with a slot 15, adapted to receive the free end of a leaf spring 16 bearing against the disx, this spring being secured in place by a ring shaped end portion 17 secured between the thimble 10 and the base of the arm extension of the base plate.7.
When the disk is in closing position, the spring will bear thereagainst to resiliently hold it in such position and said spring at all times holds the pintle extensions 13 of the plate in the bearing extensions 1a of the recess 19 of the base plate. The disk may thus be rocked outwardly by engagement with a fingerpiece extension 18 on its free end, and in this rocking movement the leaf spring will enter the slot 15. Outward movement of the heel portion of the disk is limited by abutment with the thimble 10, in which iosition it will be held by the spring 16 as shown in Figure 2- and the oil aperture of the timer casing is thus entirely unobstructed in the open position of the heel portion of the disk.
I have thus provided an exceedingly simple, readily manipulated and highly efficient closure device which will retain its desired features of operation upon continued use, it being noted that the wear incidental to movement of said heel portion of the disk is distributed along the entire end edge of the closure plate, which engages against the casing surface, thus relieving the pintle portions from excess wear.
While I have shown and described a preferred embodiment of my invention, it will be appreciated that various changes and modifications of structure may be employed to meet differing conditions of use and manufacture, without departing in any manner from the spirit of my invention.
lVhat is claimed is:
1.
