CHARLES A. BILLS, OF ST. ,JOE STATION, INDIANA.
DERRICK.
SPECIFICATION forming part of Letters Patent No. 691,349, dated January 21, 1902. i Application filed October 10,1901. Serial No. 78,250. (No model.)
To allwwm/ it' may concern,.-
Beit known that I, CHARLES A. BILLs,a citizen of the United States, residing at St. Joe Station, in the county of Dekalbv and State of Indiana, have invented a new and useful Derrick, of which the following is a specification.
My invention is an improved derrick, particularly adapted for hoisting stones and other heavyweights; and it consists in the peculiar construction and combination of devices hereinafter fully set forth and claimed.
In the accompanying drawings, Figure 1 is a side elevation of a derrick constructed in accordance with my invention. Fig. 2 is a detail sectional view taken on a plane indicated by the line a a of Fig. 1 and showing the Winches for operating the counterpoiseboom and the lowering-tackle. Fig. 3 is a similar view taken on a plane indicated by the line b b of Fig. 1. Fig. 4 is a side elevation of the upper portion of the mast, showing the drum therein on which the elevatingrope operates that raises and lowers the boom. Fig. 5 is a similar view, partly in section, of the lower portion of the mast, showing the means for operating the said drum. Fig. 6 is a detail elevation showing one of the brakes.
In the embodiment of my invention I employ a mast 1, which is journaled at its upper and lower ends in a suitable supportingframe 2. Thereby the mast is adapted to turn axially. At the lower ends of the mast, fast with and adapted to turn therewith, is a platform 3. A pair of cross-bars 4 are secured on opposite sides of the mast ata suitable distance from the lower endthereof, and the said cross-,bars are provided at Vopposite ends' with bearings'for a hoisting-boom 5 and a counterpoise-boom 6, which are disposed on opposite sides of the mast, as shown in Fig. 1. The said hoisting-boom is provided near its outer end with pulleys 7 8.
The counterpoise-boorn carries a weight 9 at its outer end. As here shown, the said weight is a tank adapted to carry a variable quantity of water, according to the weight which is to be hoisted by the derrick. The
said counterpoise-boom also carries near its outer end a pair of pulleys 10 11.
The mast is provided near its upper end with bearings, as at 12,' for a drum 13. The shaft of the said drum is Iprovidedion one side of the said mast with a brake-drum 14. and with asprocket-Wheell. (See Fig. L1.)v Ahoistingrope 16 is attached to the'boom 5 near the outer end of the latter, passes over and is'partially coiled upon the drum 13, passes over the pulley 11, carriedby thecounterpoise-boom, and is attached to a Winch 17, which is carried by the counterpoise-boom, and is disposed on the lower side thereof near Jits inner end. The winch 17 is provided at .one end of its shaft with a spur-gear 18 and at the opposite end thereof with ab'rake-drum 19. A brakeband 2O engages one side of the said brakedrum. One end of the said brake-band is secured to the counterpoise-boom andthe other end thereof is connected to the crank 21 of a rock-shaft 22. The saidrock-shaft has a crank handle or lever 23, by, which it may be actuated to applythe brake-band frictionally to the drum or release it therefrom. The said winch 17 is adapted to payout or reel in thehoisting-rope 16 in .order to dispose the counterpoise-boom at any desired angle with relation to the hoisting-boom, according to the extent to which the latter must be raised when elevating a weight.
The lowering-rope 24isattached to a block 25, which yhas a pulley 26, and is provided with grappling-hooks or other devices 27 for engaging or supporting the weight, as is here indicated at X,.Fig. 1. The saidi loweringrope passes over the pulley 8, under the pulley 26, and over the pulley 7. The said lowering-rope and said pulleys 7, 8, and 26 constitute a lowering-tackle, and the same may be varied as may be required by the'weights to be handled thereby. Said lowering-rope 21, as here shown,'passes through a guideslot 28, with which the mast is provided, passes over the direction sheave or pulley 10, with which the counterpoise-boom is provided, and is attached to and adapted to be reeled upon or unreeled from a winch 29, which is' 95 similar to the winch 17, has a gear-wheel 30 disposed at some distance from the gear 18, and is provided with a brake 31, which is similar to that with which the winch 17 is provided. A shiftable shaft 32 is journaled at IGO one end in a fixed bearing 33, in which it is loose. The said shiftable shaft is journaled near its opposite extremity inl a shifting-bar v34. The said shifting-bar is fulcrnmed on the counterpoise-boom, as at An operating-lever 36 is also fulcrumed on the said counterpoise-boom and is connected to the said shifting-bar by'a rod 37.- Hence by operating the shifting-lever 36 the shifting-bar 34 and the shiftable shaft 32 may be moved to cause apinion 38, with which said shaft is provided, to be engaged with either the gear 18 or the gear 30 at will. The said shiftable shaft has a crank-lever 32, by which it may be turned.
A shaft 39, which has a gear-wheel 40 and a sprocket-wheel 41 fast thereto, is journaled in a bearing at a suitable distance from the lower end of the mast. The said shaft has a crank 42 at one end. The gear 40 is engaged by a pinion 43, which is carried by a shaft 44,that has a crank 45,which is disposed on the opposite side of the mast from the crank 42. Said shaft 44 also has its bearing in the mast. An endless sprocket-chain 46 connects the sprocket-wheels 15 and 4i, and hence when the latter is rotated either by the crank 42 or the crank 45 power is communicated through the chain 46 and the sprocketwheel 15 to the drum 13, and the rope 16 is operated by the said drum to simultaneously move-the boom 5 and the counterpoise-boom in the same direction. Since the said booms are on opposite sides of the mast, it follows that 'one will be. elevated while the other is being lowered. By paying out or taking in the hoisting-rope 16 the boom 5 and counterpoise-boom 6 may be disposed at any desired angle with reference to each other, according to the extent to which the outer end of the boom 5 must be raised to elevate a weight to the required height. Since the weight is carried by the boom 5 and counterpoised by the Weighted counterpoise-boom ,it is evident that comparatively slight power is required to operate the hoisting-rope 16 after the boom 5 and the cou nterpoise-boom have been adjusted and to raise the weight. When the weight has been raised to the required height and the mast swung so as to dispose the weight over the point to which it has been lowered, the shiftable shaft 32 is shifted to engage its pinion 38 with the gear 30 of the loweringlwinch 29,which operates theloWering-tackle,
by which the weight is lowered, the boom 5 and the counterpoise-boom being securely held against movement during the lowering of the weight by a brake-band 47, 'which is operated by a bar 48. A spring 49, which bears on the said bar 48, normally keeps the brake-band 47 in engagement with the brakedrum 14. A`releasing pedallever 50, which is fulcrumed near the lower end of the mast and is connected ,to the bar 48 by a rod or cord 51, is provided for releasing the brakeband 47 from the drum 14 when the drum 13 is operated, as hereinbefore stated, to raise the weight.
Having thus described my invention, I
