WELL-TlLlNG COU PLER.

SPECIFICATION formingpart of Letters Patent No. 529,776, dated November 27, 1894. Application illed June 12,1894. Serial Nn. 514,333- (No model.)

Figure l, is a longitudinal vertical sectionof the improved coupler with the first section of tiling thereon and in the act of being released. Fig. 2, is a similar view showing the coupler lowering one tile upon another and about to release it, the disk C2 being removed.

Fig. 3, is a transverse lhorizontal section through the coupler on line 3 -3 Fig. 1.

My invention relates to that class of welltiling couplers in which shouldered springs and suspension and releasing devices are employed for successively lowering the tiling or tubing into a bored well to form the lining thereof. The Object of the invention is to provide such a tubing or ,tiling coupler which shall be simple in construction and which will automatically release all `tiles or tubes after the first one has been lowered in place.

A further Obj ect is to preventaccidentalreleasing of a tile or tube inits descent; also to prevent chipping or marring the edges of the tiles or tubes when the coupler is loweredinto contact therewith.

My invention consists in the construction and combination of parts hereinafter dee Vwith a series of radial pins A5 which space it scribed and specifically pointed out in the claims. v

A, represents a cylindrical block which forms the body of the coupler. This block gradually increases in diameter from its upper to its lower end and is provided with eX- ternal longitudinal grooves` A', the lower portions of which are made deeper as'shown at a. The upper ends of the grooves A merge,

into short transverse grooves A2 on the top of the block.

B, are spring arms of greater length than the block and extendingthrough the grooves A therein; the upper ends of the arms being bent inwardly at right angles as at B to fit deeper portions of the grooves.

within the grooves A2 and thus hold the spring arms and block against separating longitudinally when the `block is drawn upwardly. A band A3 enciroles the upper end of the block A and irmly binds the spring arms in 'the upper ends of the grooves A which leaves them free to spring in yand out in the lower These spring arms incline slightly outward from the deeper portions of the grooves as shown at b and are about Hush with the outer face of the lower wider end of the block'A so that they may be compressed into said grooves. Each spring arm Bis bent outwardly near its lower end to form ashoulder B2 on which the lower end of the tile or tube may rest, and from this shoulder thearm extends downwardly and inwardly on a curve or at an incline as shown at B3. The block A has a central suspension eye A4 to which a chain or cord a4 may be attached for raising or lowering the coupler.

C, is a rod extending through a lougitudi nal'bore c in the block and has a rack C on one side of its upper end for engagement with a spring catch c', and the rod is connected between its ends by links c2 with 'the lower extremities of the spring arms B. The lower end of the rod C is reduced and threaded, and on its threaded end is placed the removable disk C2 which is held in place by a nut as shown. The links c2 permit the spring arms to expand to their utmost limit at their lower shouldered ends, but will draw said arms inwardly when the rod C is pushed upwardly by the disk on its lower end striking the bottom of the woll. I

The block A is provided near its lower end Vfirm support for it, and as the lower ends Of linked loosely together, Y

the arms B are merely they cannot be simultaneously, pressed inwardly to accidentally release the tiling even though one of them should strike some obstruction in the bore of the well.

When the irst tiling section is lowered to the bottom Lof the well the rod C will be pushed inwardly by its disk G2 and the spring arms will be drawn toward each other till their shoulders are removed from the lower edge of the tiling which will then remain in the well while the coupler will then be withdrawn by the cord 0.4. In sliding upwardly the teeth on the rod O willsuccesssively slide past the latch but the latch will prevent a return movement and hence the rod C will be locked and the spring arms held in their retracted position while the coupler is being withdrawn. After the coupler has been withdrawn the disk C2 will be removed. All the succeeding tiles will be lowered in the same manner, but as each one nears the one beneath, the lower curved or inclined ends B3 will enter therein and be automatically contracted to release the tiling from the shoulders. It the lower ends of the spring arms were connected by two toggles pivoted together below the lower ends of said arms, said toggles, in striking the bottom of the well would tend to spread apart and hold the spring arms apart. It the toggles were pivoted together and to the arms within their lower ends to hold the arms against a tendency to spring inwardly and any obstruction should strike one of them both toggles would move upwardly at their inner pivoted ends and permit the spring arms to release the tiling with which the coupler could not be again connected. W'here the outer ends of such toggles form the shoulders on which the tiling rests as has been done heretofore, such projecting ends tend to chip the end of the tiling and there is a danger of such ends being clamped between twol tiling or tubing sections. All such dangers are obviated by having the spring arms free to spring apart at their lower shouldered ends and there loosely linked to the operating rod.

The disk C2 cannot strike any obstruction when the coupler is being lowered as it is of less diameter than the circle described by the spring arms and the spacing projections or pins A5 hold the coupler steady and concentric with the tiling section.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent ot the United States, is

1. Acoupler of the character described comprisinga body having a suspension device secured to its upper end, a series of depending outwardly inclined spring arms secured lixedly at their upper ends to the body and provided near their lower ends on their outer sides with integral shoulders to support a tiling section and extending downwardly and inwardly toward each other from the said shoulders for the purpose described, and an operating rod separate and independent of the said suspension device and linked to the lower ends of said springs to draw them toward each other but allowing them normally to spring apart, substantially as herein described. y

2. A coupler for the purpose described co1nprising a body having a suspension device secured to its upper end, a series of spring arms extending through the grooves and below the body and secured at their upper ends to said body, shoulders on the lower diverging ends of the arms, the said arms extending downwardly and inwardly toward each other from the said shoulders, an operating rod separate and independent of the said suspension device and extending down through the body and linked to the lower extremities of the spring arms, and provided therebelow with a disk or head, by which it is automatically op erated to move the arms inwardly to release the tile and a catch on the body to lock the rod when moved upwardly, substantially as herein described.

3. Acoupler comprising the body having external longitudinal grooves, the spring arms extending through the said grooves and having their upper ends bent over the upper face of the body, a band encircling the upper end of the body, and binding the arms thereto; the said spring arms diverging below the lower end of the body and then extending downwardly and inwardly; shoulders for the tiling being formed where the arms have their greatest divergence, an operating rod extending down through the body and linked to the lower extremities of the said spring arms, substantially as herein described.

4. A well tiling coupler, comprising a cylindrical body block A, having a suspension device on its upper end, a series of spring arms secured ixedly at their upper ends to the said block and bent outwardly below the block to form the tile-supporting shoulders and curved o'r inclined downwardly and inwardly therefrom, an operating rod extending down through the block and separate and independent of its suspension device, links connecting the rod and spring arms below the block, and pins projecting fromthe outer side of the block intermediate of the said spring arms, substantially as set forth.

5. A coupler for tiling consisting in the tapering cylindrical block having external longitudinal grooves deeper at their lower por- ICO IIO

tions, a series of spring arms secured to the y block at their upper ends and extending through said grooves about tlush with theouter face of the block, the lower ends ofthe arms being provided with shoulders and curved or inclined inwardly th erebelow, a toothed operating rod extending down through the block and connected between its ends with the lower extremities of the spring arms, and having a disk or head therebelow, substantially as herein described.
