SPEED-FINDING nnennn'ron.

Application filed. October 13, 1922. SerialNo. 594,420.

T0 all whom it may concern: I

Be it known that I, Gnoncn R. WATSON,

a citizen of the United States of America,

and a resident of Waterloo, Blackhawk County, Iowa, have invented certain new and useful Improvements in Speed-Finding Regulators, of which the following is a specification.

My invention relates to improvements in speed-finding regulators, and the object of my improvement is to supply for internal combustion engines or other prime motors or devices, means for regulating, governing, or controlling the fuel supply or other power producing means, including mechanism suitable for manual direction, in the finding or estimating the speed of the apparatus or of mechanism driven thereby.

This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which Fig. l is a view partly in elevation and partly in section, with parts broken away of my speedfinding regulator as operatively connected to the outlet-controlling valve of a carburetor such as is commonly used to supply gaseous fuel to an internal combustion engine, not shown. Fig. 2is an end elevation of said device with parts broken away.

This speed finding device is particularly designed and appropriated for use in combination with the fuel supplying means of an internal combustion engine employed to operate a well drilling machine. Well drilling machines of the larger sizes which are employed in drilling deep oil or other wells cause their drilling devices to penetrate rocky strata of different densities and hard ness, requiring various changes of speed of operation in the reciprocation or lifting and dropping of the boring tool according to the different conditions. The operator must be ready to quickly change the speed of operation according to the need. This device, therefore, is devised to afford means for the operator to quickly and efi'ectively estimate from time to time a particular speed required in the operation of the boring tool and control the motor suitably to change the speed.

In this instance, the device is operatively connected by means of a connecting-rod 20 to a orank-arm 21 on the rock-shaft 22 ofthe butterfly-valve 23- within and controlling to an engine ofthe internal combustion type which actuates the mechanism of the well drilling machine.

The numeral 1 denotes a large channelbar upon which a spaced sector 2 is fixed by appropriate fastening means such as bolts,sa1d sector having a bearing'openmg to receive a fixed shaft 3 on which an arm 4 is mounted to rock to and fro past and in contact with one face of the sector. Said arm has on the opposite side of said shaft an integral bent finger 5, whose lower end has a coiled spring connection 7 to a projection 8 on the bottom of the sector tending to yieldingly resiliently move said arm to one limit along said sector. The numeral 9 denotes a screw passed through a threaded opening in the lower part of the sector to impinge at its end against a curved surface or edge 6 of the finger 5, and the other end of said screw is provided with a crank 10 for manual use. This screw may be used in thrusting upon the finger 5 adjustably in placing said spring 7 under tension and in varying the position of the arm 4 relative to the curved edge of said sector. This arm 4 thus serves as a manually adjustable stop or abutment for a hand-lever 14-13 which latter controls the connecting rod 20 and the valve 23. When the-lever 14-13 is in.

the position shown, the spring 7 is not under tension and the butterfly valve 23 is closed. When it is desired to admit gaseous fuel to the engine, the lever 14--13 is swung'past the arm 4, and its outer part 14, after clearing said arm 4, which it can do because of the hinged connection to 13 at the forks 18 and 19, pintle 16 and torsion-spring 17 which tends to swing the part 14 toward the sector, may have its detent 15 engaged overlappingly with the stop arm 4 to hold said valve more or less open.

An experienced operator can easily control this device using his judgment as to the proper speed for a change of condition in drilling, and can adjustably find and reg-- may be terminally connected pivotally directly to the part 13 of said hand lever, but as illustrated, it is connected to a part 12 of another and slottedsector 11 which is fixed on the same sleeve as thepart 13. This latter sector may be used in connection with another connecting rod, when desired, to another part of the engine or the mechanism, but does not form a necessary element in the invention.

The part 14 may be swung back on the pintle 16 while tensioning the spring 17 to disengage from the stop arm't when it is desired to close the valve 23. v

After the adjustment of the stop-arm 4 with a desired rate of speed thereby induced in the operation of drilling, it often becomes necessary to temporarily suspend the operation. Upon resuming, if the same rate of speed is to be maintained for a time, the already adjusted stop-arm permits this, without further efiorts at speed finding or loss of time due thereto.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is:

In combination, a controllable regulating element, an adjustably mounted stop, means for adjusting the position of said stop, and a controlled resiliently jointed movable controller-device operatively connected to said regulating'element and adapted to be releasably engaged with said stop to hold said regulating element in an adjusted position.

Signed at Waterloo, Iowa, this 11th day of Sept. 1922.

GEORGE WATSON.
