WELL SHOZJTING DEVICE Filed May 28, 1930 gwuentom JJH/LL Patented Mar. 31, 1931 UNITED STATES JESSE J. HILL, OF INDEPENDENCE, KANSAS WELL-SHOOTING DEVICE Application filed May 28, 1930. Serial No. 456,586.

My invention relates to improvements in well shooting devices, and one object of my invention is the provision of a device of the character and for the purpose stated which can be lowered with ease and safety into the well, which can be timed to explode at a definite set moment and which will be positive and reliable in action and thus insure a most desirable and practical device for the purpose intended.

Another object of my invention is the provision of a well shooting device which will be composed of few parts to insure absolute certainty in action, which cannot possibly explode until the time required insuring a device which can be handled with safety and which will contain all of its parts or'elements in a single unit or structure.

Another object of my invention is the pro- 2 vision of a well shooting device which will have great shattering power to obtain the best possible results, which can be easily packed, transported and assembled and which can be made at a small price which with other advantages will make the device very useful and practical.

To attain the objects stated and such others as belong to a device of this character, my invention consists of a well shooting device embodying novel features of construction and combination of parts, substantially as described and claimed, and as shown in the accompanying drawing, in which:

Figure 1 represents a view showing the shell or casing in section and the operating parts of my device in side elevation, and illustrating the invention in complete form.

Figure 2 represents a face view of a clock of the type used in my well shooting device, and

Figure 3 represents a vertical central sectional view of the acid containing unit or element of my device, shown on an enlarged scale. I

An important aim of my invention 'is to produce a device of the most;si1nple and inexpensive construction and in carrying my invention into effect, I employ a hollow casing or shell 1, having a lowered tapered or point- 50 ed end 2, and having interior threads 3, at

the mouth to be engaged by the threads 4:, on the annular flange 5, of the cap or closure 6, which carries the yoke 7, to which in use is attached a rope or means for lowering the shell into the Well.

The hollow shell receives the shattering charge 8 upon which is placed a suitable fulminate or explosive 9, which acts, as will presently appear to ignite and fire the main or shattering charge 9'.

Fitting in the open upper end or mouth of the shell and retained by an annular shoulder 10, is a clock 11, whose face 12, is arranged uppermost, and to the back 13, of which is connected the yoke shaped hanger 14, having a band or collar clamp 15, which holds and suspends the cylindrical acid container The acid container as to structure and its relation to other parts of my invention forms a most important feature, and it is provided at its lower portion with a reduced opening or passage 17, a reduced threaded portion 18, which receives a threaded cap 19, having an outlet 20, and the cap retains in place the layer 21, of suitable material such as fullers earth and the screen or filter 22, while the threaded open top 23, of the container receives the threaded cap 24, having a filling opening 25, to receive the acid, and in the 30 threaded opening 26, in the top is mounted the threaded portion 27 of the valve stem 28.

From this construction it will'be noted that from the back of the clock is suspended a hanger in which is supported an acid containing element and that said element or container has an opening and a valve seat for the valve stem, and the valve stem contiguous with its threaded portion carries a bifurcated head or lug 29, which fits upon the key 30, of the alarm mechanism and when the said key turns and at a set and determined minute by the ringing of the alarm in the well known manner, said key turns the said head or lug 29, and also the valve stem, raising the valve from its seat and allowing the acid from the container to pass down and through the fullers earth and to drop upon the fulminate 9, and instantly fire the shatterin charge 9', to effect the shooting of the we 1 as is obvious.

From the foregoing description taken in connection with the drawing the many advan- 5 tages of my device will be readily understood and it is not thought necessary to elaborate thereon, but it will be apparent that the shell is harmless until the acid is discharged at o the determined moment and that it will not 1 act except at the time set, also that the entire mechamsm is contained in a single unit and can be transported with ease and facility and without danger,'that the shell can be easily charged by a person of ordinary intelligence and set at a time for its ex losion in the well, that the time for the exp osion can be regulated in the same manner as the setting of an alarm clock, that the device can be lowered with readiness and perfect safety into the well. and that it will never fail to explode at the time set and desired, and that generally in every respect the device will prove reliable, eficient and practical.

I claim:

at 1. In a well shooting device, the combination of a shell, a shatterin charge in said shell, a fulminate or firin c arge above said shattering charge for exp oding said shattering charge, a clock arranged above said firing so and shattering charge, and an acid containing element operated by the clock to discharge acid on said fulminate to explode said shattering charge. a

2. In a well shooting device, the combination of a shell, a lower disposed shattering charge, a surmounting fulminate or firing charge, a clock arranged in said shell above said charges, an acid container associated with said clock, and mechanism in said acid 4 container 0 eratively connected with the alarm key 0 the clock to be operated by the turning of said key at a determined time to .drop acid on said fulminate to explode said V shattering charge.

3. In a well shooting device, the combination of a shell, a shattering and firing charge carried in said shell, a-clock in said shell above said char es, an acid container disposed in proper re tion to said clock, a filtering me- ;o dium in said acid container, a valve for controlling the discharge of acid from said container, and means connecting said valve'with the alarm winding key of said clock to turn said valve to discharge the acid upon said firing charge to explode said shattering charge.

11 testimony whereof I afix my signature.

JESSE J. HILL.
