. .sEcTloNAL DERHIQK.

To all whom, t may concern.:

Beit known that-1, JOHN S. HINEs, a citi-f zen of the United States, residing in the city of Portland, inthe county'of Jay and State of Indiana,'have invented a new and useful Construction for Derricks and Meansfor Raising Them into Position, which invention I denominate a sectional derrick, of whichv the following .is a fullI and comprehensive specification and eX osition, being such as kled in the art to which it ap ertains to make and ,use the .same with abso ute exactitude. n

My invention relates to sectional derricks designed more particularly for usein connection with dee well.drilling, same to forma part of what 1s known in the vernacular o the trade as a standard rig.

The object ofthis my present invention,-

broadl speaking, is the rovisionof an improve construction of t e class stateddesigned to give a maximum of mechanical efIiciency with a minimum of expense and in which the item of maintenance will be practi- More specically stated, my object is to provide a derrick formed, preferably, entirely of metal and which is composed of va plurality of sections of upwardly-decreasing dimensions, the sections being capable of being easily collapsed or folded into a com act space and when assemple'd together to orm a rigid practically indestructible and ornate structure and at the same time being economicall eflicient and forming a standard derrick oth in eiiiciency and general` ap- .,pearances, and, nally, other'obJects are to provide a derrick which may be easily assembled and disassembled,' easily transportare shown most clearly in the accompanyin seven sheets of-drawings, yformingl a part o this specification, v in which- Figure-1 shows a side elevation of the first or lower section 1n position,'also the second j Specification of Letters Patent.

Fig. 19 is a detail showing one of the hinge-joints, and Fig. 20 is a longitudinal sectional view of one of the folding mechanisms.

.Fig 16 shows one o f the `sections folded.

Similar indices denote andrefer to like arts throughoutthe severalA views of the awmgs. j In order tov render the construction andl operation of my invention still more facile, .I nowtakeu a detail description thereof in which I will escribe the construction andA the operation thereof as briefly and as compactlyas I may.

My invention comprisesa pluralit of separable sections divided from each ot er horilzontally and constructed convergentl upf'. wardly, each section bemg substantia y of. same dimensions atits base asis the next lower section thereto at its apex- In this instance Iprovide four dlstinct sections, designated, for convenience of description, yl'etf tersA, B, C, and D, counting from the lower section upwardly.)

Said posts are formed of angle-iron in order to give them the desired strength with a minimum of height. Said posts are connected at their lower end portions by the four lower end ties, (designated by the numerals 5, 6, 7, and' 8.) At their upper ends said posts are connected by the four upper end ties 9, 10,

l

11, and 12, the latter set of ties being shorter than the former in order to give the propershape to the section. Near their centers said posts are again connected by the four horizontal ties, (designated by the

numerals

13, 14, 15, and 16,) which are parallel with the aforesaid ties. Extending between the

posts

1 and 2 and located between the

ties

9 and 13 are the crossing braces 17 and 18. Extending between the

posts

2 and 3 and located between the ties 10 and 14 are the crossing-

braces

19 and 20. Extending between the

posts

3 and 4 and located between the ties lland are the crossing braces 21 and 22, and extending ybetween the

posts

4 and 1 and located between the

ties

12 ,and 16 are the crossing braces 23 and 24.

All of said ties should be formed of angleiron, as shown. All of the various parts of 'Section A are detachably secured together by bolts, as shown, thereby completing the framework of this section, as shown in Figs. 1, 2, 3, 4, 5, 6, 9, and 12. l

Accessory parts of section A.-Secured to the rear faces and extending slightly above the upper endsv of the

posts

4 and 1 are hinge members 25 rand 26, respectively. (For, detail of hinges see Fig. 19.) Extending'between the -ties 8 and 16 are the vertical hanger-

posts

27 and 28 which carry revolubly the bull-wheel reel, which is com osed of the spindle 29 and the two bull-Whee s 30 and 31. Said reel may be operated in any well-known manner either by power or by hand, and it is ada ted to rotate in either direction. Exten ing back from the'tie 8 parallel with the ties 5 and 7 and between the wheels30 and 31 are the anglc-iron track-

bars

32 and 33,. Extending downward and rearwardly at an angle from the tie 12 and connected toand ,alined with the track-

bars

32 and 33, res ectively, are the track-

bars

34 and 35, wliich 4are for purploses hereinafter stated. Extending up t e front side of Section Afrom the center of the tie 6 to the center of the tie 10 is the ladder-section 36. t l f Section B.-

The numerals

101, 102, 103, and 104designate the four cornerposts of thisl section, which posts are substantially the same length and of same size and formed in same manner asthe posts of Section A. Said lposts of Section Bare connected together at their lower ends by the four

lower end ties

105, 106, 107, and 108, and at their upper ends said posts are connected by the four upper end ties 109, 110, 111, and 112, this latter set of the former, but suiiicient' to give the same vconverging inclination to Section B as is given to said Section A, all substantially as shown in the drawings. 'Ihis Section B is made folding or collapsible, as shown in Fig. 16, and the means for accomplishing this feature I will now describe, and as the eon.`

struction thereof is the .same` between each two of the four corner-posts I will now de scribe the rear side, as shown in Figs. 5 and 15, and the same description will apply to the o ther three sides of this section. 1

Folding means-Connecting the

posts

104 and 101 near their centers. is the two-part tie 113, the members of which overlap each other in the center, where theyy are held togetherbyaninverted-U-shapedclip, (denominated by the numeral 114.) Passing centies being shorter than y trally through the sides of the clip 114 and extending across the space between the sides thereof is an eyelet 115, (shown in Fig. 20,) there being an a erture through the end portion of the mem ersof the tie 113, bywhich said members are pivotally mounted on said eyelet.` The

numerals

116 and 117 denote two contacting vertical bars :located parallel with each other. To the upper end of the bar,116 are pivoted the inner overlapping ends lof the downwardly and inwardly extendin arms 118 119, and to the lower end of the ar 117 is pivoted the inner overlapping ends of the upwardlyand inwardly extending arms 120 121. The' outer ends of said arms 118 119' and 120 121 'are pivotally secured to the corner-posts 104'and101, as indicated. Slidably mounted around the lower portion of the bar 1161s awinged clip 122, and in like manner mounted around the upper ortion of the bar 117 is a'winged clip 128. ivoted to the wings of the winged clip 122 are the inner ends of the

arms

124 and 125, with their outer diverging ends pivoted to the respective'

posts

104 and 101 by same bolts which secure the ends of the tie l113 to said posts. -Pivoted to the wings of the winged clip 123 are the inner ends of the

larms

1,26 and 127, with their outer ends pivoted to the respecros tive

posts

104 and 101 by same bolts which secure the ends of the tie 113 to said osts. The numeral 131 denotes a band-clip shdable over'and slidably co tacting the two bars 1 16 and 117. When op ,ned out in its assembled position, as Fig. 7, I insert a,bolt 128 through corresponding apertures 'therefor in the center of the winged clip 122 and through corresponding apertures in the

bars

116 and 117. Also a bolt 129 is inserted. through corresponding apertures thereforin the winged clip 123 andthe bars 116 and 117', and the bolt 130 is inserted through corresponding ISO apertures therefor in the

bars

116 and 1 17 and throu -h the eye of said eyelet 115, and therefore t ough the membersof ,the tie 113. The operation of said parts is as follows: The device being right end upward, as in Fig. 7, but partially dismantled, as in Fig. 15, it

will be apparent that if the clip 1 14 be pressed upward then the

posts

104 and 101 may be brought toward each other, in which movement the bar 116will slide forward in the winged clip 122, and the bar 1 17 will slide upward in the winged clip 123,- the

arms

118 and 119 folding together and the arms 120 v and 121 folding together, all of said arms finally coming parallel with thpsts 104 and i 101, and allof said parts being inclosed withil? the angles of the posts 104 and`101, .as in 16.

heuabove-describ'ed folding means is identically the same between the

posts

101 and 102, 102' and 103, 103 and 104, same as it is -between the

posts

104 and 101, and therefore a description of said parts is not necessary, as the constructionv is shown most clearly in the drawings. v

If now-Section B is constructed asj'ust de-A scribed, the section beingassembled as shown in Figs. 2, 7, 8, and 12, whichA to ether show all four sides of this Section B ,y an the section may be collapsed by first removing the

lower ties

105, 106, 107, and 108 and the

upper ties

109, 110, 111,. and 112, then removm the

bolts

128, 129, and 130 from the four si es of the section. After the above the four

posts

101, 102, 103, and 104 may be brou ht'together as in Fig. 16, with all of said olding means contained in the space formed by the an les of said posts.

t is not to" be understood that I limit myself to the specific form of folding y,means above described, as it is apparent that other means may be employed for same purpose. Detaehably secured on the rear side `of Section B are the two track-bars 132 and .133, adapted to unite and be alined with the trackbars'34 and 35 of Section A.

The numeral 134 denotes the ladder-secjtion for the` Section B, which extends centrallyup the front of Section B and is alined with the ladder-section 36 of Section A.

" Secured to the rear face of and extending slightly below the lower ends of the posts A104 and 101 are the

theposts

104 and 101 are the hin e

members

137 and 138, respectively, whie will presently be further referred to in connection with Sec- Section (l-The four sides -of this section Section() comprises inits construction the and "308. The upp four comer-posts 201, 202,203, and 204, which rise. eonvergently upward, as shown in said views of the drawings. Said posts are of substantially the same length and of same form and construction'as are the corresponding posts of said Sections A and B. 'Said posts of Section C are connected together detachably at their loweryends by the four lower end ties 205-, 206,207, and 208, and at their upper ends said posts are'connect'ed detachably by the four upper end ties 209, 210,

211, and 212, this'latter set of ties of courseY .being shorter than the former, whereby said posts will incline inwardly at same inclinai tion as do thecorresponding'posts of lSections A and B therebelow. The, folding means for Section C is in every essential particular like thefolding means described in rel 4 lation to Section B, andtherefore a

repetition tions

135 and 136, respectively, of Section B.

Also secured to the rear faces of and-extending slightly above the 'pper ends of the

posts

204 and 201 are the

hi ge members

237 and 238, respectively, which will .presently be further referred to in connection with Section. D.

Section D.-The four sides of Section D are shown in Figs. 12, 9, 10,- and 11. .This section includes in its framework vthe four

cornerposts

301, 302, 303, and 304, which rise convergently upward, as shown in the drawings. `Said posts are of substantially the same length and of same form and construction as are the corresponding posts` of Sections A, B, and C. Said posts of this Section D are'detachably Aconnected together at their lower end by the four lower end ties305, 306, 307,-

er ends of said postsl are detachably -connected by the four upper end ties 309, 310, 311, and 312. This latter set of ties are shorter than theformerin order to give said posts the same inclination as the corresponding posts of Sections A, B, and C. The folding means of- Sectionl D yis in everyr essential particul-ar like the folding means described in relation to Section B, and therefore a repetition ofthe descri tion thereof is "not necessary, as it would a d nothing to elearness of comprehension, as the description of one can betaken as the descriptionof the other, the parts being shown in thedrawelhe numeral 334 denotes the ladderection ofSection D. Said -ladder extends up the front of this section and is alined with the ladder-section of Sections A, B, and C, as shown in Fig. 12.l

Secured to the rear faces of the lower ends of the

posts

304 and 301 and extending slightly above the ends thereof are the hingeA be turned up and down, as in Fig. 12, in order the side of the derrick, through which a drill-q i oo to provide a comparatively large opening 1n stem (not shown) may be taken within the inclosure of the derrick.

(jenemlities-Section A is adapted to rest on the ground or on mudsills or in any otherV manner as may be deemed advisable. Section B is adapted to rest on Section A. Secltion C is adapted to rest on Section B, and

Section Dis adapted to rest on Section C, all as shownv in Fig. 12. The corner-posts of each of the sections above Section A are adapted to rest on the corresponding cornerposts of the section next below. The corner-

posts

1, 101, 201, and 301 are ada ted to be detachably secured together byl olts or the like, as indicated in the drawings. In like manner the posts 2, 1-02, 202, and 302 are secured together, and in ,like manner the

posts

3, 103, 203, and 303 are secured togetlier, as are also the

posts

4, 104, 204, and 304. The lower end of each of said posts above'SectionA has secured to it a downwardly-extending fiange or reinforcing-shoel .which extends down over the upwardly-projecting portion of the post next below With corresponding apertures to receive retainingbolts, as indicated in some of the views. Said flanges also serve to retain the abutting ends of the posts in alinement with each other andto break the ioints between the posts. In this construction all partsof each of the sections is made entirely of metal, as has been intimated'.

Iwould call attention to the fact that the ladder-sections when assembled extend from the base to the a ex of thederrick, 'as shown in F ig; 12, each adder-section being removably connected tocits derrick-section. The track formed by the track-bars extends from some distance in the rear of the derrick only to the top of SectionB, said track being for the purpose which will resently. be explained. The working too s for manipulating a well may be sus ended insidethe' derrick from the top of ection Din any wellknown manner.

The numeral 400v denotes a truck having supporting-wheels mounted `on the ends of an L-shaped or angle-iron axle, with a tongue extending centrally out from said axle and secured by suitable braces, all substantially as shown in perspective in Fig. 17. 7o

Numeral 401 designates a'pulley-block containing two pulley-wheels arranged tandem, with their concave faces opposite to and almost in contact with each other. Said pulley-block 401 is provided with a hook at one end, whereby it may be hooked into an aperture therefor located in the center of the

ties

10, 110, and 210, where said pulley will occupy the positlons indicated in Figs. 1,2, 5, and 9.

The numeral 402 refers to a single pulleyblock which is provided withl a hook at one end, whereby it may be attached in an aperture therefor located in the centers of the ties 112 and 212, as indicated in Figs. 2, 5, 854

6, and 9.

The numeral 403 designates a lever formed of channel-iron or the like, adapted to be detachably secured to the ladder-sections of the Sections B, C, and D and to extend a con- 9o siderable distance therebelow, or rather to extend upward when said sections are nverted, and said lever is shown in Figs. 1, 2, 5, 6, and 9. Extending out at right angles from the outer end of the lever 1s an eye- 9 5 piece 403a for the purpose resently appearlng, and located a short istance from the end of .the lever and from said eyepiece is a second eyepiece 403 forV the purpose presentl appearing.

T e numeral 404 denotes a cable or the like adapted to be wound on the spindle 29, extending from thence through the .pulleyblock 401 and provided on-i ts outer end with a hook to engage in either of said eyepieces of the lever 403, as is shown in the drawings.' The numeral 405 denotesl a cable or the like adaptedto be Wound on the spindle 29, extending from thence through the pulleyblock 402, and provided on its outer end with'v a hook to engage in an aperture formed in the outer end portion of the tongue of the truck 400, as shown in Figs. 2, 5, 6, and'9.

Operation of ositioning the sections.-As before indicated Section A is assembled in the position where it is to be employed. The other sections are ,to be erected'up end down to the rear of and near Section A. Forexample, Section B is erected on the track 32 '33 with its rear side next the rear side of Section A, after which the lever 403 is attached Then the spindle 29 is revolved to Vwind thereon and tighten the cable 404 sufficient to tip Section B andbring its hinge members 137 138 in alinement and contact with thehinge IOO lus

members 25 26 of Section A, and at this time bolts are inserted to join said hinge members, thereby forming a complete 4hinge of the '

members

26 and 136 and another hinge of the

member

25 and 135. After said hinges are formed, as stated, then the spindle 29 is eventuate in lowering Section B down gradu' ally into the position itl should occupy, as shown in Fig. 2. VAfter Section B is positioned as above stated then the meeting ends of all of the corner-posts of Sections A and B are bolted together, as stated. The remaining sections to be positioned are raised as follows: Referring now to Fig. 2, the truck 400 is now laced on the track which extends back from Section A, with the tongue thereof extending upward, as shown. Section C being now assembled'and inverted, its rear upper end is rested inthe channel of the axle of said truck and the u per point of the tongue of the truck is plhced inside-that is, against lthe inner face of the tie 208, for which a notch may be provided, as is shown in Fig. 18. The cable 405 is now extended upward from the spindle 29 through the pulley-block` 402, and the hook on the outer end of said cable is attached in the aperture 400a in the outer portion of the tongue of the truck. N ow if the spindle 29 be revolved it is manifest that Section C will be elevated, being carried on the truckthe. wheels of the truck traveling up the tracks until the hinge members 235 and .236 are alined and contacted with .the

respective hinge members

137 and 138 of Section B.

Pivot-bolts are theni nsertedto join said respective pairs of hinge'members, and thereby complete the hinges, as in Fig. 5. After the above the cable 404 is brought into play, the hook of said cable being attached in the eyepiece 403", as in Fig. 5, and the lower portion of the cable 404 is attached on the spindle 29 and adapted to be wound thereon, reversely from the winding thereon of the cable 405.

Now at this point the spindle 29 is revolved oppositely to its last rotation, to wind thereon the cable .404, which of course will unwind the cable 405, which will eventuate in turning Section C on its hinges', as shown in Fig. 5, and simultaneouslywith the turning and raising of Section C the truck Will belowered-that is, it will travel down the track, Section C coming to its upright position synchronously with the truck, reaching the horizontal ortion of the track ready' for a new load. he lower ends of the postsof Section C are now secured to the upper ends of the osts of Section B, as indicated in Fig. 6.y

he cables areA now unwound from the spindle 29 and the pulley-

blocks

401,and 402 are moved up tothe top of Section C,vbeing secured in same manner as before to correspondin parts of the last-named section. Section is now placed on the truck, as in Fig. 6, the lcable 405 being then attached as before, and Section D is raised, and its

hinge members

335 and 336 are pivotally connected to the

hinge members

237 and 238, as in Fig. 9, and the Section D is then raised and the truck lowered in saine manner as before stated in relation Aof Section-C, after which the lower ends of the osts of Section D are secured to the upper ens of the posts of Section C, which will complete the derrick ready for its employment in the usual manner. After the derrick has been assembled as above set forth thenthe pulleys 401 and 402 may be removed. Also the lever 403 is removed, and, ifdesired, the said cables maybe removed, or they'may be employed for other purposes, all to again be brought into employment in dismembering the derrick.

Dtsmembering-Desirin now to dismantle and remove the derric the reverse o eration is taken in lowering the sections, tffe only dierence being that the hook on the cable 404 is to be attached in the eye ieee 403a in place of the eyepiece 403", the o ject in this being to top the section either forward lor backwardbeyond the point of balance or equipoise, (seeFig. 1,) depending on Whether the section is being posltioned or removed, respectively. After all the sections have been'l taken down from pyramidal contact they-are each (except Section A) collapsed and folded, as shown in Figs. 15 and 16. It is intended that Section A should be entirely dismembered, after which all of the parts may be loaded in a small compass of space and trans orted to a new location. i

While have shown and described the best means to me known at this time for carryin out the objects of my invention in a practica manner, I desire to have it distinctlyvunderstood that, I do not restrict myself to the exact detailsl of construction shown and described, but hold that any changes or variations therein as would suggest themselves to an ordinary mechanic would clearly fall within thelimits and scope of my invention.

The terms upward downward, horizontal, verticah and other similar `terms are used for convenience of descri tion, and it is not intended by the use of suc terms to limit my invention to the relative positions indicated thereby.
