Description
UNITED STATES PATENT OFFICE.
MILES JOY, OF WEST GREENVILLE, PENNSYLVANIA.
IMPROVEM ENT IN BORING-TOOLS.
Specification-forming part ot Letters Patent No. 49,277, dated August 8, 1865.
To all 'whom 'it may concern.-
Be it known that I, MiLEs JOY, of Wes Greenville, in the county of Mercer and State of Pennsylvania, have invented a new and Improved Jar for Well-Boring Tools; and I do hereby declare that the following is a full, clear, and exact description thereof, which will en- -able those skilled in the art to make and useY the same, reference being had to the accompanying drawings, forming part of this specification, in whichj latter becoming fast, being subjected to a series oi' blows or concussione, in order to loosen it. This device, commonly termed a jarf7 is indispensable in boring deep wells,'owin g to the great difficulty which would be otherwise experienced in withdrawing or loosening the auger.
The ordinary jar in use is attended with some disadvantages. It is liable to get fast itself, and is subjected to considerable wear in consequence of being in contact with-the grit in the Wall of the Well. It is also liable to break or give way when worn, and the with'- drawing of it from the well is attended with considerable difticulty. These disadvantages, it is believed, are fully obviated by my invention.
My invention consists of a pipe, A, which may be a piece of gas-pipe of any suitable dimensions-say three inches in diameter and two feet in length-with a screw-plug, B, having a socket, a, attached, welded into its'lower end. The upper end of the pipe A has a thimble, (l, screwed upon and welded fast to it, the
b, for an instrument to grasp'in case of a break or giving way of the parts above the pipe.
The thirnble (l has a steel plug, D, iitted in it, having a square hole, c, through it for the center rod, E, to workthrough, the rod E having'a steel head, F, on its lower end.
By this arrangement it will be seen that the pipe Aand auger or drill below it will be turned in case the'rope which is attached to rod E is turned for that purpose. y
The pipeA has a slot, d, made in it, extending nearly its whole length, to admit of the ready escape of water from the pipe, so that the formerwcannot interfere with the concusj sions produced by the falling of the rod E.
From the above description it will be seen that in the event of the auger getting fast the latter may be subjected to a series of jars or i concussions by operating the rod said rod being raised until its head F comes in contact j with the plug C, and then allowed to drop, so that the head will strike the upper end of the plug B inthe lower end of pipe A.
By this arrangement all the parts are pert'ectly protected, and thedevice is consequently durable, not liable to be ai'ected -by wear or A become deranged by use.
I claim as new and desire to secure by Letters Patenti,- l
A' jar for a well-boring apparatus, coin posed of a pipe, A, having a slot, d, in it extending j nearly its Whole length, a plug, B, secured in its lower end, and a thimble,0, on its upper end, containing a plug, D, having a square holemade in it for a rod, E, to work` through ywhich rod E is provided with a head, F, at its lower end, said pipe Ainclosing the rod E, with its head F, and protecting itfrom injury,
substantially as herein described'.
