Application October 24, 1999, Serial No;- 301,059

' 10 Claims. (Cries-16) This invention relates to a mud box particularly intended for use with the pipe or tub-ing of a rotary drilling rig, and it is an object of the invention to provide a box of this kind for use in connection with large size pipes or to carry a heavy load.

It is also an object of the invention to provide a box of this kind including hingedly mounted side plates operatively connected at spaced points therealong with an equalizing bar, together with means associated with said equalizing bar for swinging the side plates into either open or closed position.

Another object of the invention is to provide a box of this kind including hingedly mounted side plates having means to assure proper relative relation of said side plates when closed and wherein is provided an equalizingbar for swinging said side plates with regulatable means for limiting'the inward movement of the equalizing bar past center.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved mud box whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth;

-The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings', wherein:

Figure 1 is a View in side elevation of 'a mud box constructed in accordance with an embodiment of my invention with a portion broken away;

Figure 2 is a view lustrated in Figure omitted;

Figure 3 is a view in rear elevation of the structure as illustrated in Figure 1 with parts in section and the intermediate portion of the pull lever in top plan of the box as il- 1 withthe suspending cable 7' broken away;

lustrated in the accompanying drawings, I denotesan elongated back plate arcuate in cross section. The side or longitudinal marginal portions of the plate I are provided therealong with the spaced sleeves or knuckles 2 between which are snugly received the spaced knuckles 3 carried by the inner longitudinal side or marginal portions of the side plates 4 also arcuate in cross section. Disposed through the interfitting knuckles or sleeves 2 and 3 are pintles 5 whereby the side plates 4' are hingedly connected to the back plate I.

When the plates 4 are in closed position they coact with the back or rear plate I to provide a substantially cylindrical box which, when in ap plied or working position, surrounds a drill tube or stem D above and below the connection 6 between adjacent sections of the tube or stem D.

The opposite end portions of the back plate I have welded or otherwise securely fastened thereto the inwardly disposed flanges l and bolted, as at 8, to the inner face of the top flange 7 is the arcuate packing block 9 of a rubber compound. This block 9 is adapted to tightly contact with a peripheral portion of the drill tube or stem D to which the box is applied.

The upper and lower end portions of the side plates 4 also have welded or otherwise securely applied thereto the inwardly disposed flanges It} to the inner faces of the top flanges of which are bolted, as at H, or otherwise secured thereto the packing blocks l2 for close contact with pe ripheral portions of the tube or stem D.

. The several packingblocks 9 and I2 and the lower flanges I and ID are so formed that when the side plates 4 are in closed position around'the drill tube or stem D said blocks 9 and I2 coact to provide packing elements entirely surrounding the tube or stem D at all points above and below the connection or joint 6 between adjacent sections of the drill tube or stem B after said connection or joint has been raised up above the rotary.

, The side plates 4 have secured thereto at desired points spaced lengthwise thereof the rearwardly directed arms M. The arms M of one of the side plates 4 have their outer end portions pivotally connected, as at Hi, to the outer end portions of the links l6. These links I6, extend inwardly of the plate I and the inner end portions of these links l6 have freely disposed therethrough the end portions of an elongated equalizing bar I1. The arms 14 of the second side plate 4 have pivotally connected, as at l8, to the outer end portions thereof the clevises IS in each of which threads a shank 20. The outer portion of each of these shanks is formed to provide a flattened head 2! which is received between the inner end portions of a pair of links I6 and thru which head the equalizing bar I! is also freely directed. This bar I7 throughout its major portion and particularly at those portions which are disposed through the links it and heads 2|, is circular in cross section. The bar ll above and below each pair of links [6 has disposed therethrough the cotter pins 22 whereby the bar ll is maintained in desired assembly with respect to the links l 9 and the shanks 29.

The bar 5'! at its longitudinal center has pivotally secured thereto, as at 23, the spaced short links 24. These links 24 extend outwardly and rearwardly from the bar l1 and are pivotally connected, as at 25, with the intermediate portion of a pull lever 26 passing between said links 24.

The lever 29 is disposed in a direction lengthwise of the rear plate l and the upper portion of said lever 26 is pivotally supported, as at 27, between a pair of outstanding gears 28 carried by the upper end portion of the back or rear plate I. This lever 26 is of such length desired and upon swinging the lower end portion of the lever 26 outwardly the side plates 4 will have their outer marginal portions separated a distance suiflcient- 1y to allow the box to be readily applied to' or removed from working position with respect to the drill tube or stem D. In applying the box to the stem or drill tube D, inward swinging movement of the lever 29 will cause the side plates 4 to assume a closed position whereby the stem or drill tube D is entirely surrounded as clearly illustrated in the accompanying drawings. The upper or pivoted end portion of the lever 29 is continued by an extended portion 29 through which is threaded a shank 39. This shank 36 constitutes an adjustable stop and is maintained in its selected adjustment by a jam nut 3!. As is believed to be obvious, the extent of outward movement of the side plates 4 will be determined by contact of the inner extremity of the shank 39 with the rear or back plate I and more particularly the upstanding hanger 32 welded or otherwise fixedly secured to the upper portion of the back or rear plate 5. This plate or hanger 32 is adapted to have secured thereto a cable 33 whereby the box in its entirety may be suspended in the derrick.

The lever 29 inwardly of its pivotal mounting 2'! is outwardly oilset, as at 34, so that there will be no interference between the upper portion of the lever 26 and the connections between theupper arms i4 and the equalizing bar ll.

It is to be noted that the flanges I0 of one of the side plates (Figures 2 and 6) terminate a distance inwardly from the outer longitudinal edge of such plate. The flanges E9 of the second side plate extend beyond the outer longitudinal edge of said second plate so that the flanges II] of said second plate will slip beyond the longitudinal margin of the first plate when said plates 4 are closed, thus assuring the closed plates 4 having their outer marginal portions in proper alignment so that a true circle of the box is assured.

The longitudinal marginal portion of the sec-- end plate 4; is defined by an outwardly disposed and angularly related lip 34 which serves as a striker or guide to facilitate the full closing of the plates 4. v

The side or longitudinal marginal portions of the back or rear plate I are provided therealong with the sealing strips 35 to lap the adjacent marginal portions of the side plates 4 when in closed position to prevent leakage between the closed plates l and 4. The outer longitudinal marginal portion of one of the plates 4 also carries a closing or sealing strip 36 to lap the adjacent outer longitudinal marginal portion of the second plate 4.

The lower portion of one of the side plates 4 is provided with a drain nipple 34, herein disclosed as closed by a removable plug 38. This nipple 31 provides means for recovering samples when making a drill stem test.

The opposite end portions of the equalizing bar I! have threaded therein the bolts or set screws 39 projecting from the bar I! in a direction toward the rear or back plate I. Engaged on these bolts or set screws 39 are the jam nuts 40 whereby the bolts or screws may be effectively maintained in desired adjustment. The contact of the outer ends of these bolts or set screws 39 with the back or rear plate I limit the extent of movement of the equalizing bar I! inwardly beyond the vertical center. The limiting of this movement is of importance because undue movement of the bar ll inwardly beyond its center requires considerable outward pull upon the lever 26 to unlock the side plates 4 for outward swinging movement. It is believed to be obvious that upon slight movement of the bar I! inwardly beyond the vertical center the side plates 4 are effectively held against opening or outward swing.

The bottom flanges 1 and H] do not have any packing associated therewith as it is not desired that these lower flanges 1 and I0 have sealing contact with the drill tube or stem D. On the contrary, these lower flanges 1 and I0, when the box is closed, are slightly spaced from the tube or stem D to allow fluid within the closed box to re-enter the well after the stem or drill tube D has been lifted.

The invention as comprised in this application is an improvement over the mud box as embodied in my pending application Serial No. 268,090 filed April 15, 1939. The invention as embodied in this present application particularly differs from what is shown in my previously filed application with respect to the equalizing bar I! with which the lever 26 is operatively engaged together with the features of the extended portions of certain of the flanges l9 lapping the outer marginal portion of a second side plate 4. The present invention also comes within the scope of the invention as embodied in my prior application and, therefore, the present application may be considered a continuation in part of this former application Serial No. 268,090.

From the foregoing description it is thought to be obvious that a mud box constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
