DERRICK.
957,239. Specification of Letters we. P t t d May 10, 1919 Application filed December 29, 1909. Serial No. 535,612.
To all w7w'm tt may concern: tion of bolt .10, which latter is passed Be it known that I, JOHN MOVEIGH, a through the outer end of link 7 end pivot- 66 of the United States, residing ,at ally connects the link 7 with the beam. Phlladelphia In the county of Philadelphia 11, 11, represent parallel links, which are and State 0 Pennsylvania, have invented perforated at their ends and are disposed on certain new and useful Improvements in opposite sides of the mast"1 and beam 8,
V. rricks, of which the following is a specinear their upper ends, end are pivotally se- 60 ficatlon. cured to the mast and beam bv means of .My invention relates to improvements in bolts 12 and 13-respectively. n opposite derricks, th'eobject of the iny ention being to sides of link 7, plates 14: are secured and are provide an improved mounting for the beam provided with perforations 15, so that when which enables the beam to be swung from a bolt 13 is removed and beam 8 swung around 66 horizontal to a substantially vertical posiwith bolt as a fulcrum the opening near Ttion, so as to swing the lo d in and out with the end of the beam 8 will register with the" relation to the mast, without elevating the openings 15 in the plates 14, and bolt 13 load to any appreciable extent, andfurther, me be positioned through the openings 15 to provide a construction of this kind which and the opening in the end of the beam 8 to is ca able 'o'f adjustment,whereby the beam secure the beam 8 and link 7 together, and
1 may e utilized as an ordinary swingingverm form a single long arm or beam, as shown from {the-mast.
most clearly in Fig. 5. With these and ot-her objects in view, the By referring to Figs. 1 .aznd 2, benm 81st I invention consists in certain novel features its lower free end is provided with .0. fixed of. construction and combinations and arpin 16, to which one end of a lifting cable rangements .of parts, as will be more fully 17 is fixed. -This cable 17 passes downward a. similar view showing the parts in a differhereinafter described and pointed out in the aroiind a block 18 for supportiug't-he load claims. 19, and then up and around :a sheave 29,.
In the accompanying drawings: Figure 1 thence along the side'of beam 8 vend around is a view in elevation illustrating my ima sheave '21 at the upper end of the beam,
proved derrick in one position. Fig. 2 is thence across-to mast 1 and around a sheave 22 on the most, thence down .slongside'lihe ent position. Fig. 3 is an enlarged view in mast and, around the sheaves 23 and .24 :at,
' section on the line 33 of Fig. 1. Fig. 4. is the lower end of the most, 831d thence to on mounting at its lower end, in a block or base a detail View of one of the links 7. Fig. 5 operating drum 25. A. cable .26 for is a. view showing the parts adjusted for opthe; beam inwardly toward the mast, :is w oration as an ordinary arm or beam, and cured at one end to the bolt 10, thence ex? Figs. 6 7, and 8, are detailed views of the ,tends'across and around a. sheave 27 on the 'lin 7, beam '8,- :ind'm'ast 1, respectively. mast 1, thence down and around she'aves 28 1 represents the mast whic has rotary and 29 at the lower end of the mast,'a1 1d thence to an operating drum 30. A" cable 2, and is braced by stays 3 engaging a jour- 31 for swinging the arm out and ewayfron'i 119.1 pin 4 at the upper end of they most, so as the mast is secured to'the inner end of beam to support the must but not interfere'with 8, thence extends across and around a'sheave '96 'themast, tit-a point above its lower endits turning movement. To oppositesides-of 32 on most 1, thence down and around sheaves 33 'a.nd 34 at the lowerend of the plates 5' are secured endproject out beyon mast, and thence to an operating drum 35.
I the mast, and are perforatedv to receive a The operation of the structure shown in secured to opposite' sides of the beam and ivotally connect a link 7 to the Figs.'1, 2, and 3, is as follows: To elevate mast, said ink having-an opening in its end the load, drum 25 is turned which serves to receive the bolt 6. to draw the cable 17 and lift the load to- B'represents the beam, which is provided .-ward the free end of the beam. To swing at a, point between its ends with plates 9' the beam inward and bring the load close to the mast, drum 30 1s turned to draw cable 26, and this pull on the beam 8 at theboltj bolt 6 to having registering openings for the recepbeam para 101 with link 7; bolt 13 7 downward and swin the arm outward and this arm may be swung out to practically a'horizontal position, and therefore by means of a structure of this kind, the beam may be moved from a practically vertical, to ahorizontal position, thus permitting a Wide range of movement for thebeam.
As shown in Fig. 5, when an ordinary arm beam is desired, bolt 13 may beremoved, when the links 11 will fall down beside the mast 1, out of the way, andwhen the beam 8 is-swun on the pivot 10 'to bring "the may bepassed through the openings 15 in plates 14: and through the opening in the beam 8, so as to secure the beam '8 and the 0 1k 7 together and fornr a single long arfiigwheir of course, the cables will require someslight arrangement to properly manipulate an arm of this kind.
Various slight changes might be made in the general form and arrangement'of parts described Without departing from my invention, and bencel do not restrict myself to the precise details set "forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. In a derrick, the combination with a mast and a beam, of a link pivotally connected at one end to the mast and at its outer end to the beam between the ends of the latter, and a pair of links pivotally conmast at a nected to the beam and mast near their up per ends, substantially as set forth.
2. In a derrick, the con'lbinatioi'l with a mast and a beam, of a link pivotally connected at one end to the mast'and at its outer end to the beam l)(Et'v\'L'(?l1lll(. ends of the latter, links above the first mentioned link pivotally connecting the mast and the beam, and plates secured to the firs-timeotioned link between their ends and between which the end of 'said beam is adapted to be secured when detached from said upper links.
3. In a derrick, the combination with a must, of oertorated plates secured to the point removed -from its lower end, a beam, perforated plates secured .to the beam between the ends of the latter, a link pizotally connected at its ends between the plates on the mast and the lates on the beam, perforated plates secured to the Hider; of said link, upper links pirotally secured tothe mast and to the beam, said beam adapted to be swung to'a. position between the plates on the lower link and secured between the plates on the lower link.
4. In a derrick, the combination with a mast: and a beam, of a link pivotally connecting the lower portion of the mast with the beam betwccnthc ends of the latter, an upper pairot links connecting the upper portions of the beam and mast, a lifting cable connected to the free end of the beam,
a second cable connected to the beam at. its pivotal juncture with the lower link, a third cable connected to the upper end of the beam, and means for o 'ierating said cables, 7
substantially as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. I p
