' HAY-LOADING DERRICK.
Specification of Letters Patent.
Patented Aug. 18, 1914.
Application filed. May 5 1913. Serial No. 765,508.
Be it known that I, WILLIAM L. TULL, a citizen of the United States, residing at Gridley, in the county of Butte, State of California, have invented, certain new and useful Improvements in Hay-Loading Derricks; and I do declare the following to be for derricks used for loading andstacking hay or similar products, the object of the invention being to produce such a derrick as can be easily set up for operation and one in which the llftlng and" swinging move- I ment necessary to unload and stack the hay from wagons or other places maybe done easily and quickly and with muchless energy than is required in the present commonly used derricks. a
A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective forthe purposes for whichvit is designed. p a These objects, I accomplish by means of such structure and relative arrangement of the parts as willfully appear by a perusal of the following specification and claims.
Figure, 1 is aside elevation of the complete device installed ready for use. Fig. 2 is a top plan'view of an adjustable control means to control the swinging move ment of the mast and boom. Fig. 3'isja sectional view taken on a' line XX of Fig. 1. Fig. 4: 'is a detachedfragmentary view of a knock-down hinge structure.
Referring now more particularly to the characters of reference on the drawings, the
- numeral 1 designates the main supporting base frame of the device which is suitably mounted upon any desired carrying. means such as wheels 2. Thebase frame 1 is provided with a plurality of inclined stayor brace members 3 carryin'g'at their upper end a circular collar or guide 4:.
The numeral 5 designates a suitable base member suitably secured to the frame 1 in which is turnably mounted a pin 6 of the mast 7. The said mast 7 is composed of two parts, the adjacent ends of eachbeing provlded with a-pair of projecting flanges S and Strespectively, those flanges on one side of each part being permanently hinged together by pins!) and those on the other side being adapted to be removably joined by means of bolts 10 whereby when the bolts 10 are removed tlie'mast will be broken at'this point andinclined -downwardly to get it out of the way for transportation purposes. To this end the boom is also collapsiblymounted as follows, namely:
The numeral 11 designates thefixed arm secured to the mast 7 while the numeral 12 designates the movable arm pivoted to the arm 11 as at 18. The said arm 12 is held in elevated position and is adjustable to various positions desired by means of a cable lt secured'to the outer end of the arm 12 as at let: The'cable 14 then projects over a pulley 15 in the top of the mast 7 and over a pulley '16 in the outer end of the arm 11 and then over a pulley 17 disposed with in the bodyof the mast 7 and is then secured to a drum 18 mounted on a shaft 19 journaled on the side of the nast 7 and pro-' vided with an operating handle 20.
The numeral 21 designates a ratchet dog adapted to engage a ratchet wheel 22 on the shaft 19 .to hold thesame in fixed position.
Thus by the operation. of the handle 20, the
position of the arm 12 may be adjusted or it may be entirely lowered to lie parallel against the mast-7 and then when saidma'st is broken and inclined downwardly the upper portion thereof and ,the arm 12 may be secured in horizontal portatlon purposes.
The top of the mast when set up is suitposition for transbly held in position by means of. stay members 23 secured'to' a top plate 24 in which the said mast 7 is revolubly disposed. Said mast? is also stayed on eachpart'by means of vertical stays 25 lying parallel thereto and secured at each end of each part. The mast turns through the member 1 as a guide and'is provided with a plurality of rollers 26 to hold the same in trueposition;v
The fork'hoisting andmast turning mechanism consists of a cable 27 connected to the fork 28,- "w-hich cable extends over a pulley '29 in the outer end of the arm 12 thence over a pulley 30 in the top of the mast 7, thence over a pulley 31 in the outer end of the arm 11, thence through a pulley 32 adjacent to the pulley 17, thence over a pulley 33 in the lower end of the mast 7. Said cable then projects through my adjustable control mechanism for the swinging movement for the mast and boom, which control mechanism consists of the following structure, namely: The numeral 34 designates'a projecting arm on the lower end of the mast 7 slidable over which is a sleeve 35 adapted to be fixed in any desired position by means ofbolts or set screws 36. On said member 35 are a pair of straps 37 in which is turnable a tubular member SScarrying a frame 39 on its outer end inwhich is turnablea pulley 40. A projecting arm 41 is pivotally mounted to the frame 39 as at 42 and carries in its outer end a pulley d8. Mounted on the member 41 is a clamp 4st slidably adjustable longitudinally onthe said member 41 and on the member 38 isa similar member 45. Secured to .the members as and 45 are projectingarms 4-6 and d7 respectively which are pivoted together as at 18. Said member 47 projects beyond the pivotal point and is provided with a plate t? adapted to impinge against the member 1-1; By means of this structure it can be readily seen that the relative angle of the. member ll with respect to the member 38 may be changed and since the cable 27 projects through the tubular member 38 and around the pulley 40 and the pulley 43 when the fork 28 is raised, the same operation will also coinmence to turn themast .and boom to swing it out over the stack or other place desired and the speed at which this turning motion can be accomplished is determined by the angle between the members 38 and %1, the nujustability of the arm 11 being to allow of this function. Also since the member 38 isturnable in the straps 37, the entire mechanism may be turned from side to side so that the position from which the pull may be exerted on the cable 27 may be set according to which way the mast and boom are to turn. The member 35 is provided at its outer end with twoprojecting plates 19 to support the frame 39 and its connected parts.
From the foregoing description it will be readily seen that I have produced such a de vice as substantially fulfils the object of the invention as set forth herein.
While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention. 1
Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is 1. In a derrick, the combination with a pivoted mast, of an arm projecting outwardly from the lower end of said mast, a sleeve slidable over said arm and capable of being fixed rigidly thereto, a pulley in the outer end of said sleeve, an arm pivotally mounted at the outer end of said sleeve and having a pulley in its outer end, said arm being adjustably connected with said sleeve, as described.
2. In a derrick, the combination with a pivoted mast, of an arm projecting outwardly from ,the lower end of said mast, a sleeve slidable" over said arm and capable of being fixed rigidly thereto, an arm pivotally mounted at the outer endof said sleeve and provided with a pulley in its outer end, a clamp slidable on said arm, another clamp slidably mounted with respect to said sleeve, and a pairof arms, each of said arms being pivotally connected with one of said clamps and with each other, as described.
3. In a derrick, the combination with pivoted mast, of a member projecting outwardly from, the lower end of said mast, another member turnable on said last named member and provided with a pulley in its outer end, an arm pivotally mounted at the outer end of said turnable member and provided with a pulley in its outer end,and means connecting said arm with said turnable member whereby the angle between said arm and said turnable member may be varied, as described.
In a derrick, the combination with a pivoted mast, of an arm projecting outwardly from the lower end of said mast, a sleeve slidable on said arm and capable of being fixed thereto, a member turnably mounted on said sleeve and provided with a pulley in its outer end, an arm pivotally mounted at the outer end of said turnable member and provided with a pulley at its outer end, a clamp slidably mounted on said arm, a similar clamp slidably mounted on said turnable member, a pair of arms, each of said pair of arms being pivotally connected with one of said clamps and with each other, as described. I
In testimony whereof I afliX my signature in presence of twowitnesses.
