ROTARY JAB.
Wirbel le. IAUM* lated October S, 1923, Serial reirme led December 17,
may concern:
Be it known that I, Jamas ALLEN KAM- Marsman, a citizen of the United States,
f lo
as commonly practiced in drilling wells for oil-.,filhe jars are used to assist in loosening"` tools which become stuck in the hole, and are especially usefulwhen fishing for lost tools. In hydraulic rotary drilling,
it isjessential that a circulation of water or water and mud be maintained in the hole. This circulation is to prevent the settling of drillings in the bottom of the hole, as such settlin may freeze the drill pipe or tools fast 1n the hole. vCirculation mustA be kept up, even though drilling ceases..
-In spite of these recautions the pipe and tools will at timeslliecome stuck'in the hole.
oircul'etion.,
The prim objects of this invention are list, to provi e a'jar which may be tripped a jar whic movement' second, to provide is adapted to be placed in a string of drill pipe, and will not interfere with circulation at vvany time and will permit by arota rotation of the string. In addition to the perspective views of the su broader objects of this invention, there are certain details of-4 structure, whereby a strong, simplez economical, and easily mani ulated jar 1s obtained.
ese objects together with other objects and corresponding accomplishments. are obtained by means of the embodiment of my invention illustrated' in the accompanying drawing, in which: v Fig. 1 is a perspective view of the complete jar with sections thereof broken away to better show vthe structure; Fi 2 is an axial section through the 'ar; 3 is a perspective' view of the T;, igs. 4 and 5 are Referring more particularly tok the the upper `,s ub has a male tool ointpgtion on` a body 7 and a head 8.

slidably redeive a conduit. The
u end of the bore is enlarged and threadldextb receive a cking gland 10. The lower portion of t e head 1s reduced in diameter and .threaded as indicated by 11 Extending transversely across the lower portion of the' head is a pocket 12 to receive the head of the T so as to. form a clutch therewith for the purpose of rotating the string of pipe. This sub is a rotary sub. The lower sub 14 is-of the same extern diameter as the head of the rotary sub, is
reduced in diameter and threaded as indicated by'15. .The lower sub has a bore 16v I to slidably receive the leg of the T. The bore is enlarged and threaded to receive a packing gland 17. The upper portion of the lower sub is provided wlth a pocket 18 to receive the head of the T, and the uper faces of the sub areinclined downwar ly in the same direction towardthe bottom of the pocket. The stock of the impact sub is extended to form posts 19'to limit turning of the T.
- Connectin the subs is a bowl 20. This bowl provi es a chamber in which the T may be moved. The T comprises av tubular leg 21I having a tool joint at its lower end and a head 2 2 such that it may be dis' posed in either cket 12 or pocket 18. The upper face oft e T head is flat so that it may be disposed to snugly rest in the pocket 12, and the lower faces are in-v clined to conform to the inclination of the faces on the impact sub.
Extending from the head' and threadedly secured thereto is a tubular crown member 23. which slidably passes through the upper sub. It is obvious that the T is so arranged that it maybe moved from the pocket 18 in the impact sub to the pocket 12 in the rotary7 sub. In either position there is a complete closed passage way extending from the tool joint in the upper plug to the tool joint inthe lower sub. The packin glands 1n the subs permit the chamber in t e bowl to be'filled with grease t'allow easy operation and to prevent leakage of the ase from the bowl or entrance of mud an sand into the bowl.
When it is desired-to rotate the strin of pipe, the string is lowered until `the ead 22 of the T reposes in the cket 12 on the rotary sub. -If the head o the T does not register with the pocket, the string may This sub is anI impact sub.
lill
be given a slight turn until the head finds its position and drops into thepocket. The posts 19 end short of the rotary sub so that there is suiiicient clearance for tlfel turning f the head when' resting against the lower 'face of the rotary sub. Suppose it is demay disengage t sired to raise a tool by means of the strin of ipe, the string is raised and the T hea wil 'drop into the pocket 18. If the' tool is stuck: and the strain is not sufficient toloosen it, the string is lowered a slight amount so that-the T head 22 clears the upper face of the impact sub and the bowl is then turned so that the T rests upon the face of the impact sub across the pocket. A strain is then placed upon the string by pullinor it upward. The bowl is then turned until the T head registers with the pocket 18, 'whereupon Athe T will snap into the pocket thereby jarring the stringand loosening the tool. Thus, a rotary trip is provided, there being two sections slackly linked together. The inclined faces-of the T on the impact sub assist the head in sliding into position inthe pocket. The posts 19 on the lowei` sub prevent the T from turning too far when resting on the faces of the impact sub.
What I claim is: v
l. A rotary jar .comprising two sections slackly linked together and rotatable with respect to one another, shoulders on said sections arranged so that they may engage one another and hold said sections in a contracted position, said shoulders being arranged so that by rotating said sections they ereby trlpping and permitting the sections to be arrested by impact of the linked parts.

A rotary jar comprising two sections slackly linked together so as to be contracted and expanded and to 4have relative rotary movement, trip means to arrest the movement of said sections intermediate in a contracted position and to take a tensile strain, said trip means being arranged to be released by relative rotation of said sections and to freely permit movement of said sections to their expanded'position where they 1 are arrested bynmpact.v
1 3. A rota jar adapted to be connected in a string 'o pipe comprising a section havlng a sup ort with a pocket at one end, two sections s ackly linked thereto and having a T member arranged to rest ugon4 said su port at the sides of said poc et or to within saidpocket, whereby turning of said sections relative to one another will trip said T intov I'said pocket.
4. A rotary jar adapted to be connected in a string of pipe comprising a bowl .section having a chamber provided with'a" pocket at one end, a tubular T slidably extending into said chamber and having a head arranged to fit within said pocket 'and means of sai to connect the bore of said T with said bowl so as to provide a closed expansible passage through said jar, the head of said T being .arranged to be disposed out of said pocket and to rest upon the end across said pocket or to .be disposed in said pocket at will.
5. A rgtary jar adapted to be connected in a string of pipe comprising a bowl secvtion having a c amber provided with. a
pocket in its upper wall and a corresponding ocket in its lower wall, a tubular T slid`a ly extending into said chamber having a head arranged to fit within said pocket, and means to connect the bore of said T to said bowl so as to provide a closed expansible assage through said jar, the h ead of said) T being arranged to be disposed out of said pocket or insaid pocket at will.
7. A rotary jar adapted to be connected in a string of pipe comprising a rotary sub' having a transverse pocket, an impact sub having a transverse pocket, a cylindrical bowl connecting said subs and yforming a `tion having a chamber, said bowl section chamber, a tubular T slidably extending vide a closed expansible passage through said jar.
8. A rotary jar adapted to be connected in a string of pipe comprising a rotary sub having a transverse pocket, an impact sub having a transverse pocket, a cylindrical bowl connecting said subs and forming a Ichamber, a tubular T slidably extending into saidvchamber and having a head arranged to fit within either of vsaid ockets a tubular extension mounted ofi sai T and slidably extending through said rotary head so as to provide a'closed expansible passage through said jar. l
9. rotary jar adapted to be connected in'a string of pipe comprising an impact sub having a transverse pocket, the faces of said impact he'ad being inclined at the pocket, -a rotary s'ub having a* transverse pocket, a cylindrical bowl connectin said subs and forming a chamber, a tubu ar T slidably extending into said chamber and havin a head arranged to fit withineither pockets', and means to' connect the lli) W subs and forming a chamber, a tubular T slidab1yfeiztending into said chamber andV having :a head arranged lto fit vWithin either of said pockets, a tubular extension mounted on said T and slidably extending through said rotary head so as to provide a closed expansible passage through said jar.
