MANIFOLD CLOSURE LOCK.
Application filed March 12, 1923,
To all whom it may concern." Be it known that I, ORA E JONES, a citizen of the United States, residing at Medicine Lake, in the county of Sheridan and, State of Montana, have invented certain new andpseful Improvements in Manifold Closure Locks, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to intake manifolds, and more particularly to an attachment for the intake manifold affording means for closing the intake manifold against the passage of fuel therethroughand'for locking the closure in such closed position.
Animportant object. of the invention is to providefa device of this character so con-f structed that any attempt to destroy the locking oft-he device by the removal of the lock will result in further locking of the operating knob of a combination look. In
7 closure.
A still further object of the invention is to provide a device of this character which "may bereadily applied to the intake manifold, which is simple in its construction and operation, durable, and eflicient in service.
These and other objects I attain by the. structure shown in the accompanying draw-" ings, wherein forthe-purpose of illustration 1s shown a preferred embodiment of my inventlon and wherein like reference charac- .ters designate like parts throughout.
Ling the mounting of the auxiliary locking In the drawings Figure 1 1s a vertical sectional view taken through a manifold closure lock constructed device and Figure 4 is aside elevation showing the device applied to a manifold.
Referring nowmore particularly to the drawings, the numeral 10 designates a casing which will be formed-as a casting, which is provided at one side with a' removable plate 11 which, when removed, permits of access to the casing. Through opposed walls of the casing 11 is directed a conduit 12 held in position by means of suitable lock nuts 13 disposed interiorly'of the casing. The
' ends of this conduit 12 are formed for the reception of the ends of the intake pipe 13 of an intake'manifold M subsequently to the Serial no. 624,580.
severing of such intake pipe to form the same into two separate sections.
Arranged within the conduit 12 is a valve 14, the stem 15 of which is rotatably mounted in the walls of'the conduit. The conduit 12 is preferably formed in two sections 12 and 12 having flanged, coacting ends, as indicated at 16, each of which is formed with one half of a bearing for theshaft 15. One
end of the shaft. 15 is extended, as at 17, to form an operating portion, such operating portion being squared as regards that portion thereof extending beyond the hear- 'ing.
Mounted uponthat wall of the casing 10 toward which the stem 17 .is directed is a lock member 18 including a shiftable locking part 19 and an operating part 20 accessible exteriorly of the casing for operation and in the present instance disclosed as the the last named wall of the casing 10 adjacent the lock, and more particularly the locking part 19 thereof, is formed a bearing 21 in which is rotatably mounted a stub shaft 22 having formed at one side thereof a stop lug 23. This lug is so constructed that when the valve 14 is closed and the locking part 19 is in locking position the lug engages. therewith to prevent rotation of the shaft 22 in one direction. the wall of the casing is a stop member 24 against which the lug likewise engages when the valve is closed and this stop member limits rotation in the opposite direction.
shaft 15 and the other of which receives a reduced squared shank 26 formed upon a,
Carried by i From the foregoing it will be seen that means are provided for operating the valve 14'to open and close the same, and means are provided for locking the operating means in position with the valve 14' closed and that accordingly where a device of this character is applied to an intake manifold unauthorized use of the vehicle is rendered impossible.
In order to prevent destruction of this locking effect-by removal of the lock 18, I mount upon the conduit 12 a support 28 upon which I pivot a lever 29, one end of which is connected by a readily broken flexible connection to the lock housing as indicated at 30. Upon the conduit 12, I mount a guide and housing member 31 in which I slidably mount a fork 32 ofa'size to receive between the arms thereof the squared shank 17 of the shaft 15. A spring normally urges this fork into engagement with the squared shank, such engagement being prevented by theenga-gement in an eye 34: formed upon the stem 35 of the shank of a pin 36 extending through the wall of the housing 31 and connected'to the free end of the lever 29. The outer end of this pin 36 has a fork receiving between the arms thereof the free end of the lever 29, and between a shoulder formed upon the pin adjacent this fork and the adjacent wall of the housing 31 a'compression spring 37 surrounds the pin bearing at one end against the shoulder and at the oppositeend against the housing. It will be obvious that if the lock casing 18 is forced inwardly or otherwise removed the freeend of the lever will be released for movement, since if the, lock is ulled'through'tlie casing wall the 'flexible connection 30 will be broken and if the lock is forced inwardly the lower end of the lever will be moved inwardly andthis free end will be separated from the adjacent face of the housing. The pin 36 thus becomes free to move and its spring 37 engaging against the shoulder forces thepin outwardly, resulting in the withdrawal of the pin from the eye 3st and the freeing of the fork 32 for movement under the action of its spring :33 into engagement with the shank 17 of the valve stem. Attention is directed to the fact that the housing 31 is so formed as to render the fork 32 inaccessible and accordingly even though an opening be formed in the wall of the casing by destruction of the lock, the fork 32 remains inaccessible and continues the locking of the valve.
It will be obvious that by means of the structure above provided it will be impossible to release the valve for movement by destruction of the locking element. It will furthermore be obvious that this structure is capable of a considerable range of variation and I accordingly do not limit myself to such specific structure except as hereinafter claimed. a
What is claimed is l. In combination with an intake manifold having'the intake pipe thereof formed in two separable sections, a casing insertible between. the sections, and having a cenduit extending therethrough whereby the sections may be connected, a valve in said conduit and having a stem, an operating handle extended through the wall of the casing and engaged with the stem to rotate the same, a
look within the casing having a withdrawable locking part preventing rotation of the operating handle in a direction to open a valve, and means within the casing and engaging the stem of the valve to prevent rotation thereof upon destruction of the easling of said lock.

4. In combination with an intake manifold having the intake pipe thereof formed in two separable sections, a casing insertible between the sections and having a conduit extending therethrough whereby the sections may be connected, a valve in said conduit and having a stem, an operating handle extended through the wall of the casing and engaged with the stem to rotate the same, a look within the casing having a Withdrawable locking part preventing rotation of the operating handle in a direction to open a valve, and means within the casing and engaging the stem of the valve to prevent rotation thereof upon destruction of the casing of said lock, including a squared portion formed on the stem of the valve, a guide directed toward said squared portion, a fork slidable in the guide and adapted to engage said squared portion and by its engagement to prevent rotation thereof, a spring shifting said fork toward such squared portion, means connecting the lock casing and the fork for preventing move ment of the fork while the lock casing is in position, and a housing for said fork combining with the valve stem to completely enclose the fork.
In testimony whereof I hereunto afiix my signature.
