Application flledSeptember 7, 1923. Serial No. 661,477.
To all whom it may concern:
Be it known that I, FRANK L. HANNA, a citizen of the United States of America, and a resident of Wichita, in the county of Sedgwick and State of Kansas, have invented a new and Improved Hinged Spider, of which the following is a description.
My invention relates to the steel spider employed on a drill well casing to suspend the same in the lowering of the casing in the well.
I The form of spider very generally employed consists of a solid'forge steel ring, the use of which has serious limitations particularly in various possible emergencies. For example, if a string of casing sections is being lowered into a well and is still distant from the bottom of the drill hole, should the casing sheave in the crown block break and leave the casing suspended on the elevator with the collar of the top joint of the casing sections materially above the derrick floor, the tension on the casing line or cable cannot be relieved to let the elevator down to the floor nor can the casing sections be raised to the next collar below, and the ordinary spider cannot be emplaced over the casing or pipe because it is impossible to release the hold.
The general object of my invention is to provide a spider that may be clamped about the pipe casing under all conditions to suspend the same in the hole while the necessary repairs to the crown block can be made or other emergencies dealt with.
More specifically the invention has for an object to provide for a construction of spider reflecting practical considerations with ref spect to strength and simplicity and the convenience with which the spider may be emplaced and removed.
Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely illustrative of one example of the invention.
Figurel is a perspective view of a spider for oil well cas1n s embodying myinvention, parts being roken away and others shown in section;
tiona external ring or body of the spider, the liner and slip members or grips being re 2 is a front elevation of the sec- I omitted, said view, Figure 2, showing the spider for the purpose of the drawing as turned vertically instead of horizontally when in the normal position for use;
Figure 3 is a plan view of the external ring or body.
In carrying out my invention in accordance with the illustrated example, the spider is formed with an external ring or body 10 formed of two sections hinged together by means of lugs 11 on the sections and a hinge pin 12 passing through said lugs. At the free ends of the sections a pair of lugs 13 isformed on one section and a single lug 14 on the opposite section, said lugs 13 and 14 having respectively alinin pin holes 15, 16 to receive a tapering pin 1 held by a chain 18 to one of the sections, by a suitable fastener 19 secured at a socket recess 20 in one lug 13. The sections havehandles 21 for convenience in closing and opening the ring 10 and otherwise manipulating the spider.
The sections of the ring 10 having concave depressions 22 jointly forming a bore when the ring 10 is closed about a pipe A above the derrick floor B. The bore 22 of the ring 10 receives a tapered liner 23, having suitable handles 24, saidliner being made in half sections. The tapering bore presented by the liner 23 receives slips or sectorshaped gripping elements 25 having teeth-26 to grip the pipe A. The slips or sectors 25 are each provided with a handle 27 for convenience in the placing and removal of the slips.
With the above construction the spider may be clamped about a pipe or casing section A under anyconditions or at any point above the floor B so that the spider can be applied to the casing under all conditions and in all'emergencies. The described construction also, it will be observed, obviously possesses strength and promotes facility in the assemblage or disassemblage of the spider parts in emplacing and removing the spider. Pin 17 when in alined holes 15, 16 firmly holds the spider in closed form.
I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claim.
Having thus described my invention, I claim:
As a new article of manufacture, a spider for application to Well casings, said spider comprising a body composed of hinge sections jointly presenting a bore, a separate sectional liner in the bore of said body, and a sectional gripper fitting the bore of said liner and adapted to bind on the Well casing, said body sections, said liner sections and said gripper sections having handles thereon at the top.
FRANK LEE HANNA.
