lMPROVEMENT IN SUKER-ROD .DRAWERS FOR DEIEF WELLS.

The Schedule referred to ln these Letters Patent and making part of the same. l

bottom of a'long pumping-rod, reaching nearly or quite tothe bottom of the well, commonly five hundred to eight hundred feet. This long pumping-rod is made up of a series of rods, each fifteen to twenty feet long, called sucker-rods,4 screwed together endwise.

. Sucker-rods commonly are of wood, v ironed oi, as

A thirnble-socket (a Ashort iron tube, with the oriice a plain hole at one end, and a tubular screw at the other,) is fastened to each end of each rod, the plain hole over the wood, by rivets laterally through the iron and wood;` a screw-pin, a short iron bar round at the ends, and -a screw on each end adapted to the tubular screws onthe socket-thimbles, with a short square or angular body between the screws, for convenience of holding and 'griping, isthen screwed into a thirnble of each rod,thus, when tinished, leaving each rod with a screw-thirnhle or4 mortise at one end and a screw-tenori at theother;l

and, practically, the rods are joined by screwing the the foot of one onto the head of another.

Putting in sucker-rods to a well has been done heretofore commonly, as follows: l

-To a chain or rope 4from a windlass attach a short iron bar, having a socket at the other end, in which is aitubular screw, to fit over the screw-pin 'of a sucker-rod; screw the socket of this bar onto the head ci' -a sucker-rod, and letit into the well till the ;quare or angular' part of the screw-pin is down to the top of' the well; unscrew the iron v4bar, screw it onto another' rod, screw the other end of the other rod onto the upper end of the one in the well, and let both into the well -till the screw-pin of the last is 'down to the top of the well, and so on; and l drawing sucker-rods is the same process, partly reversed.

This, invention is a modification and improvement of my improved tube-drawer, which is the subject oi' la separate application for a patent, and its 0bject is to hold a sucker-rod, suspended by a gripe around the angular vpart of the screw-pin, instead of by a thimble screwed onto the end; and..

lhernatnre ofthe invention is to adapt the socket of my improved tube-drawerto fit onto and gripe the angular body of' the -screw-pin of a sucker-rod.

llhe following description and accompanying drawing, having like 'letters of' reference, fully illustrate the invention.

A is a socket or main body lof a clamp to go over and hold a sucker-rod.

f B is a bail, pivoted to the socket A and adapted to swing over and hold downthe screw-pin of a sucker-rod, when in placewithin thesocket.

C is a swivel attached to the top of the bail B.

l) is a part, showing one end of' a sucker-rod.

E is a socket-thimble, adapted to go over the end of a sucker-rod, D, and with a tubular screw in the end ofthe thimble part.

F is a screw-pin,- with .a screw 'on each end, adapted to fit into the end of a socket-thimblm'E.

a is a slot or mortise vertically through the socket A, and laterally open through at one side, and through nearly to the side opposite, large enough to go over easily and gripe closely the angular part of the screw-pin F. l) is a recess or rabbet over and around the slot a in the socket A, from thetop vertically, part wayy through, adapted to iit and receive and make a seat' for the shoulder of a screw-pin, F.

c is theangular main body of the screw-piu, F, large enough in diameter between any two of its dat sides to fill and easily go in the slot a of the sock.- et A.

(l. is a shoulderl ou the screw-pin F, between the angular body c and the screw at each end, projecting radially out beyond the screw and any flat side.

c is a screw on each end of each screw-pin F, and

on the inside of the thirnble end of eac-l1 socketthimble E. y fis afproject-iou on the back side' 0I' the socket A, vopposite to the opening of the slot a, for convenience of holding a socket over a well, and for the bail B to rest on when swung down.

'g is a long shank or handle tothe bail B, if deg sired.

To work the invention, put the slot a. of the socket A over and onto the angular body c of the screw-pin head F of a sucker-rod,-D; lift up the socket till a shoulder', d, of the sucker-rod, strikes and rests on the seat or rabbet l); swing the bail B over the head of the sucker-rod; attach arope or chain from a windlass to the swivel C, and let down or draw up, as desired.

'The merit of the invention is theineans of holding and handling sucker-rods, when suspended, by griping around them, instead of screwing a socket into their heads. 1t is a much safer and handler way, and saves much time; and the essential feature oi' the invention is in adapting the socket-aperture oi' my improved tube-drawer to lit a shoulder and two fiat sides of a sucker-rod head, as hereiubefore described.

I claim- A-sucker-rod drawer, in which a slot and recess of a holdin g-socket are adapted to receive and hold a combined sucker-rod, substantially as described.
