Exon/arme APPARATUS.
Application le'dctober 20, 1923. Serial No. 669,692.
To all whom t may concern.'
Be it known that I, CHRISTIAN L. HAN- SEN, a citizen of the United States, residing in Charles City, in Floyd County, in the State of Iowa, have invented certain new and useful Improvements ineExcavating Apparatus, and have described thesame in the following specification, illustrated by the accompanying drawings.
My inventionr relates in generall to that class of excavators which `are commonly used in digging ditches, canals and the like, and in forming embankments, and which individually comprise a drag bucket, or the like, and means, connected with a source of power, forloperatively lilling and emptying the bucket as well as for suspending the same while transferring it from the place of loading to the place of dumping. In apparatus of this class my invention relates particularly to those ex cavators which, like that describedl in patent application No. 636,549, filed by myself and another May 4, 1923, comprise a drag bucket, a gate for the, front end -of the bucket and means for yopening and closing the gate. It is the main object of the invention to provide means whereby gates of the general character described in said patent application may rbe conveniently combined with all, or nearly all, patterns of drag buckets in common use; to prevent parts of the apparatus from becoming bent by use and from becoming inoperative by reason of the deformation; to prevent parts of the apparatus from operatively striking the ground in advance of the bucket, when dropped, and from being bent or broken by so doing; and in gemeral to increase the simplicity and 'efficiency of dragline buckets having gates. To accomplish these objects I incorporate in my improved apparatus as parts thereof .a hauling bail having separate gr branches which are connected with' the bucket and with the mechanism for opening the gate respectively and a y pair of levers, resembling bellcranks, 'which are pivotally fulcrumed on 4the trunnions of the bucket respectively and are connected rigidly with the bucket gate as well as operatively with the bucket bails.
In said drawings, illustrating the best manner in which I have contemplated applying the principles of the invention, Fig.
1 is a side elevation of an excavating afp-- paratus which is constructed 1n accordancel closing a detail on the section line 6-6 of Fig. 1,l
with the addition of a locking bolt. Fig. is a detail on the section line 7--7 of Fig. 1.
In the illustrated specimen of the invention the bucket is denoted generally by the numeral 7.- Ithas the approximately parallel side walls 8, slightly convergent from front to rear, the arcuate bridge 9, span-A `ning the front end of the bucket from side to side, and the Hoor 10, having the an.
The hauling bail 14, bein bifurcated behind the spreader bar 19, as at each end two branches 27- and 28, which are attached respectively to the bucket body by the bolts 48 and to the slidable bars 26 by bolts 49. These branches are of such predetermined length that when the bail is tensioned the branches 28 will draw the slidable bars forward and thereby open. the gate before the branches 27 will draw the bucket forward in its filling position on theground. By the junction plate 22 this bail is linked to the hauling rope 23 and to the holding rope 25, which runs on the pulley 2O and is attached to the top of the bridge 9 by the bolt 33.
In the operation of this excavating apparatus tension exerted upon the hauling bail 14 by the hauling rope 23, and communicated by the branches 28, the unlocked sliding bars 26, the levers 37 `and the lever arms 15iirst actuates and opens the gate 12, which is then retained in the position shown in Fig. 1 by continuance of the tension. Further tension from the hauling bail, being transmitted by the branches 27 to the body of the bucket, draws the latter forward on and into the soil, sand, mud or other lilling material, whereby the bucket is loaded in the manner of drag buckets in general. After the bucket has been lilled in this manner, upward tension is exerted on the hoisting bail by the cable 18. The resulting movement of this bail relative to the body of the bucket, first turns the levers 37 on the trunnions 16 to the position shown in. full lines in Fig. 4, andvthereby forcibly lowers and closes the gate. Then as the upnaeoev ward tension continues, the bucket is hoisted from the ground. Throughout the hoisting of the bucket and until the time of its dumping, it is held in an approximately horizontal position, as shown in Fig. 4, either by the hauling bail, tensioned from the hauling rope 23, or by the holding rope 25, tensioned from the same source, or by both of these instrumentalities conjointly. In this position, and with the gate closed, the suspended bucket may be transferred to the place of dumping by an appropriate movement of the suspending cable 18, as is usual with other drag buckets. l ,The hauling rope is then relaxed by the attendant and thereby the' holding rope 25 is also relaxed, the bucket is tilted forward by gravity to the discharging position shown in Fig. 5, the gate 12 is automatically pulled open by the chain 21, as shown in the same figure, and the load is dropped. Then the bucket may be swung back to its work for another load; and so on repetitiously.
