1 Application filed October 16,

To all whom it may concern:

Be it known that I, PARKER C. THoMi SON, a citizen of the United States, and'resL- dent of Wright .City, county of Warren, State of Missouri, have invented certain new and useful Improvements in Combination Lock Mechanism for Valves, of which the following is a specification.-

This invention relates to improvements in a combination lock mechanism for valves, and has for its object a combination tumbler mechanism so located in a suitable housing and arranged to be broughtin contact with a lever mechanism directly connected to a valve for' locking said valve in a cut-off position whenever it is desired to do so.

A further object of'this invention is to construct a device which can be used for controlling the manipulation of the valve wherever the valve may be applicable, such as on automobiles, water supply pipes for buildings, gas, or in fact any purpose where valves are used in connection with a pipe system; and where it is found necessary at times to lock the valve and keep the same in a locked position, in order to prevent passage of the liquid or gas.

The essential object of my invention is to construct a combination lockmechanism arranged conveniently on an automobile, the valve being arranged in the pipe connection anywhere between the fuel tank and the engine and to be able to close thevalve and view of my invention showing the combispective view of the dog made use ofin connation dial and the handle by which the I valve mechanism is controlled. Fig. 3, is a vertical sectional view of the same, taken approximately through the center of the combination locking mechanism. Fig. 4, is a view of one side of one of the tumbler disks madeuse of. Fig. 5, is a reversed view of the same. Fig. 6, is a detail side view of the combined tumbler mechanism detached from the casing. Fig. .7, is an edge view of the same. Fig. 8, is a top plan view of the same. Fig. 9, is a detail pernection with the tumbler mechanism. Fig.

10, is a detail perspectiveiview of the valve operating arm. Fig. 11, is a detail perspective view of one of the connecting links made use of in completing the valve operating mechanism. Fig. 12, is a detail perspective view of the valve locking plunger. Fig. 13, is a detail central sectional view of the primary tumbler disk.

In the construction of my invention I provide a suitable casing or housing 14, arranged into an upper compartment 15, for the housing-of the tumbler mechanism 7 and a lower compartment 1,6, for the housing of'the valve and its opening mechanism.

These two compartments are divided by a. wall 17, this wall being provided with an opening 18, through which the valve locking plunger 19, operates whenever the tumbler mechanism is removed from its position over the opening or aperture 18. The valve opcrating mechanism consists in addition to 1 the valve locking plunger 19, of a rocking arm 20, firmly secured to a shaft 21, which has bearing in a projection 22, formed on the rear wall of the housing; the forward end of said shaft projecting through the front wall 23, of thehousing and on the same is a handle 24, by which said shaft can be operated. The one end 25 of the rocking arm is pivotally attached to the valve of said rocking arm is connected'to links 26, each formed as shown in Fig. 11. The bifurcated ends 27, of the links, straddle the valve operating arms 28, which are two in looking plunger'19, and the opposite end number and constructed as that shown in Fig. 10. r The square opening 29 of the arms is firmly fitted over the valve stem 30, which controls the inner operating mechanism of the Valve 3 1,'vvhioh valve may be of any,"

ordinary construction by which the fluid passing through the connecting pipes 32, may be shut-off.

' The combination locking mechanism which.

is located inthe compartment 15, consists of. a casting 33, having a dependent'arm 34:,

which is arranged to contact with the upper surface of. the valve lo'cklng plunger, and said casting above the dependlng arm ter-' minates' into a wider and broader portion; the same having an internal recess or opendisks36, 37, and 38. The top of this casting is provided with an integral cross-bar'39,

from which projects a guide 40, under which the dog 41, is located and held from lateral" :bar 43, which extends the entire width of the casting, and is for the purpose to lodge vtumblersin alinement whenever said tumwithin the recesses 44, formed on the tum blerdisks, for holding and locking said bler disks are in position by whichthe entire mechanism can be releasedfrom its looking position over the top of the valve looking plunger 19. The front wall of the hous- '-ing is provided with asleeve 45, on which the casting is mounted and in this sleeve is inserted a spindle 46, which 1s formed lntegral'with the knob 47, which operates the dial 48, for manipulating theicombination; And to the rear end of the spindle 46, is

firmly attached a primary tumbler disk 49. This disk is provided with anotch or recess ,50, on its outside in which the tooth-51, of

the dog is designed to be seated, and on the lnner surface of the disk 18 a pro ecting pm '52; this pin operates in a groove 53, formed on one surface of the tumbler disk 38, the

- groove having a projection 54, against which the pin 52, contacts for rotating this particular tumbler disk. The opposite surface of this disk is also provided with a pin which rides in a groove 55, formed in the disk 37. The construction is identical with the groove 53, of the disk 38, and its opposite surface is provided with a pin which rides in a similar groove in the disk 36, whose construction is identical with those previously described. I

7 On one wall of the housing is firmly lolated lugs or

projections

56 and 57, and are in a position as shown in Figs. 1 and 9. These lugs are for the purpose to limit the upward movement of the bar 43, of the dog; and when the tumbler mechanism is shifted to one side as shown by dotted lines in Fig. 1, so that its dependent lug is away from the plunger.

while in this position.

' .When looking the valve or placing the samein a position as shown in Fig'. 1, the knob of the combination is turned so that the mechanism is directly over the plunger,

. as shown by solid lines in Fig. 1. When in thisposition the bar 43, of the dog, is brought away fromthe under surfacev of the lug 56, and ispermitted to rise slightly above: the periphery of the tumbler disks, when operating the knob'tothe left in order to disengage 'or mix-up. the tumbler disks,

and by turning the knob to'the left the dog itself into a notch 59, formed in the plunger 60, located on the shaft. The object of this is to. prevent the valve mechani m from shifting when in open position and this is particularly designed as a safeguard when the device is used on automobiles, in order to prevent the mechanism from accidentally j olting of the running machine.

Having fully described my invention what I claim is; 1. A .device of, the character described comprising a casing having an upper compartment and a lower compartment; a spindle extending into the upper compartment;

' a plurality of tumbler disks located thereon,
