ANCHOR MECHANISM.

Patented Mar. 12, 1918.

mmeas- To all whom it may concern: a it Be it known that I, G ARLns ia jcitizen of the United States, residing at fR'ouseville, in the county of Venarigopand 1 i a enemies A. WAITZ, or no sEvILnE, PEnnsYLvanIA. 1

Auct on lrncnaivismi State} otPennsylvania, have invented new l and i-iiseful 1 Improvements in "Anchor Mechanisms, of which the following is a specifi cation! r I 1 i 3 Q This inventionfrelates to anchor mechainthe construction thereof as will be here-- inafter fully described and pointed out in nisms and consists in certain improvements 1 In order to'shoot a well it has been oustomary to place ananchor in the well ad3acent to theposition that it is desired to have the torpedo explode. Devices of this character have been formed so that they might be lowered into the well and the anchor disengaged from the line with which it is loweredflandtripped soas toengage the side Straub #615,321, dated Dec. 898; In the use of the anchor shownin Straub patent it a has been customary to locate the torpedo by some support extend distance dropped in this manner so that the operation has required thelowering of the an chor,the droppingof the weight torelease it, the removal of theiline and then the measuring of the position of the anchor, and the fillingin of the support so as to sustain the torpedo at theusual height.

With the present invention the anchor;

" is -released by means acting through the line a j Wltll which a is'lowered. In the exemplifica- 1.

tion of theinvention asshown this is accomplished by manipulating the line. This does I away with the double operation in that the measuringline may be used for lowering the anchor and the anchorcan be accurately placed and measured by a'single operation.

The invention is illustrated in the accompanying drawmgs as follows:

anchor, 2 the top plate, S'the hinge between the topplates, 4: the engaging pointslof the members 1 -1, 5 studs arranged on the insides of the members 11, 6 springs arranged onthe studs 5, 'Z-Zshoulders on the bottom of the members 1 -1, these shoulders being slightly undercut andformed by per- .forations in the bottom, and 8 a trigger by which the members are locked in closed position, the trigger having the shoulders 99 operating in connection with the shoulders 77. In a general way these parts are similar to the parts shown in the Straub patent" and operate in the manner therein described;

A pocket 10 is arranged in the members 1lat their meeting edges, the pockets havingthe lips'llw A releasingpin 12 has the shoulder 18 which is arranged in the pocket 10 and engages the lips 11. When the mem bers 1l are'in their closed position the'pin 12, therefore, will support the anchor. The

pin 12 extends throughf-anbpening 14 in the top 2.and terminates in ahead 15.

" A link l6is arranged between the head 15' and a spring 17. The spring 17 is arranged in a weightls, the weight being in the 'form of a pipe surrounding the spring. A snapl9is secured to the upper end of thespring, the upper end ,of the spring extending through a cap 20 on the top of theweight 18 1so that theweight 18 is carried in this manner.. A measuring line 21, having the graduations 22 is secured to the snap.

; The operation of the device is as follows The members 1,1 areclosed. NVith the pin 12in place the members are locked in this closed position by the'trigger 8. The meas- V uring line 21 is hooked on to. the upper end of the mechanism and the anchor is then lowered into the well to the position desired. Theline is then given ashort, quick upward movement and suddenly released. Asa result the spring 17is first-expanded and as the line is released the recoil of the spring brings the weight down on the pin and this blow acting on the pin forces the trigger ofi? the bottom of the "anchor, thus releasing the anchor members .l1. These anchor membersare immediately expanded bringing the points 4-4 into engagement with the side walls ofthe opening and positively locking the anchor in place in the well. This same opening of the members 1-l releases the pin 12 as the lips 11 -11 pass oil the shoulder 13.

After the disengagement of'the' anchor,
