Specification of Letters Patent.
Patented June 23, 1908.
Application filed-flovember 1907; Serial No. 400,661.
To (L73 whom it may concerns" Be, it known that I, Gnannns-Coornn, a
gibzen of the United States, residing at Garten City, in the county of Finney and State may be'utilized to help raise other loads.
angles to To these ends, as well as others of a minor nature, the device is constructed substantially as described hereinafter and shown in the accompanying drawin s, in which Figure 1 is a si e view 0 the complete machine; Fig. 2 is a vertical sectional view of the lower art of the main beam, at ri ht ig. 1, and sho wthe metho of attaching the windlasses. ig. 3 is a perspective view of'the plate which serves for t e attaching of the guys to'the top of the main beam. Fig. 4 is a pers ective view of clamp which is used to attac 1the booms to the main-beam. Fig. 5 is a view conesponding to Fig. 1, but taken from the opposite side of the derrick. Fig. 6 is a vertical section of the top of the main beam. Fig. 7 is a like view of the bottom of this beam. Fig. 8 is a section of the end of either of the booms.
The block A upon which the derrick rests is preferably of wood, having a Tshaped slot extending approximately to its center, and containing in this slot a rectangular reinforcing plate. This plate is preferably of steel and has for its purpose to apply the compressive stress to the wood over a considerable area. The main beam B .consists in a pipe or steel tube in the base of which is secured a spindle C, the latter bein retained by means of a bolt 0' and a balibitt filling C The beam may be strengthened throughout part or all of its length by an internal tube as shown in Figs. 2 and 7.
D designates a clamp which is adapted to support the booms F and G. This clamp has formed upon one side a projecting part,
. block and tackle QR, R- bein in this case as shown in Fig. 4', the purpose of wh ch will be hereinafter explained.
E-E are the usual clamps for attaching the booms tothe main beam.
In the top of the beam B is inserted a spindle H which is retained therein by a double fI-bolt J, which in turn supports the blocks V and W.
I represents a top plate that fits down over thespindle, and serves for the attachment of the derrick guys, as shown.
' K designates a suitable cross-bar, preferably 'of pipe, which is clamped to the main beam B and chained to booms F and G. This cross-bar maintains the booms in given" angular relation and may obviously be adjusted up or down the main beam.
Referring more particularly to Figs. 1 and 2, L represents what I term an equalizer, and M a snub Windlass, which are pivotally mounted upon the main beam by bolts.
Upon the outer face of the equalizer is secured a handle N, this handle being attached to the respective bolt by a nut X and to the drum by a key, as shown. A handle 0 is similarly secured to the snub- Windlass by the nut vY and a key.
P represents a single block, and Q, a double .block secured by chains to booms F and G,
res ectively.
and T designate the excavating buckets.
In the outer end of each of the swinging booms is laced a su plementary telescoping section whereby t e boom may be lengthene A rope or cable is attached to the bucket T and extends upward through pulley P then downward around the e'qualizir, then up through block Q, and terminating in the a single block. Obviousl 0t er arrangements of blockand tac e may be made.
Thus a double block may be substituted for the singleblo'ck R.
I prefer to have a small supplementar cable (not shown) extend fromR up to a bloc similar to Q and arranged at the same point (but not shown) then down and around the snub-Windlass. This cable will serve to help raise the bucket S as will be obvious. It 1s also clear that when bucket S is once. raised,
its weight in descending will help lift bucket T, and vice versa. Adjusting ropes or cables extend from the outer ends of the booms u over the corresponding blocks U and V, an 110 down through the loop or projectin ortion of the clamp Dr to the Windlass The clamp thus operates as a rope guide.
Having now described my invention, what I claim and desire to secureby Letters Patent is:
1. In a device ofclass described, a main I beam, a base therefor, having an internal retensible boomsgivotallymounted thereon, a
rope guiding c amp secured-to the main beam and supporting said booms, a crossarm mounted onthe main beam and secured to said booms and being adapted to main- I tain saidbooms in given an ular relation, an equallzer and-a snub wind ass mounted 'on opposite sides of the main beam, the former being adapted to raise balanced loads and the latter being adapted to adjust said booms.
And this zgeclfication is signed and dated at Garden lty, in Finney county, in the State of Kansas, on this 22nd day of October "HARLES COOPER. Witnesses:
JOHN A. LITTLER, WILLIAM C. PEARCE.
