EARTH-BORING TOOL.
Application filed May 26, 1921. Serial No. 472,637.
connection with machines, preferably power operated, for boring holes in the ground in which to set posts, poles and the like.
One object of my invention is to provide a structure which, after certain depth has been reached, may be removed from the hole and will elevate all of the loose dirt therefrom.
Another object of my invention is to so construct the device that, after it has been raised out of the hole, its contents may be discharged without requiring that its rotation be stopped, the discharge being accomplished in such a manner that the contents are placed a sufficient distance from the edge of the hole to prevent any of the dirt fall.-
ing back thereinto.
Other objects of my invention will be described in the specification.
The novelty of my invention will hereinafter be more fully set forth and specifically pointed out in the claims.
In the accompanying drawing:
Fig. 1 is a side elevation of a device embodying my invention.
Fig. 2 is a view similar to-Fig. l, the de vice being turned a quarter turn.
Fig. 3 is a plan view of the device, the frame member being in section, and some of the upper parts being removed.
The same numerals of reference are used to indicate identical parts in all the figures.
This device is primarily intended for use on the machine such as shown in my Patent ilr1,369,9i1 of March 1, 1921, and in so far as the parts of this device correspond to the parts there shown and described, I will refer to them by the same numerals of reference.
The power operated auger shaft 17 which projects below the bearing 34, carries on its lower end the connecting sleeve by means of which the tool is attached to the earth boring machine, the tool comprising a frame member 1., the upper portion of which is engaged by the connecting sleeve 60, the
frame member beii'ig bent as shown more clearly in Fig. 1 and extending downwardly and being split and spread to form the members 2 to the lower face of which a knife carrying disk 3 is attached, this disk being cut out at 42 and carrying a knife 5 which removably attached to the disk 3 as by bolts 6.
rt spur 7 is carried by the disk 3 and serves as a centering means for the tool when in operation.
A bucket 8 carried by bail members 9 is carried by the frame member 1, being pivotally mounted thereon as at 10, the bail memb each forming a crank arm 11 to which links 12 are connected the links extending to and being connected with a collar 13 which is mounted free to slide on the auger shaft 17, a compression spring li being mounted between the collar 13 and the connecting sleeve 60.
The bucket 8 is formed with a channel 15, as shown more clearly in Fig. 3 which embraces the frame member 1. this channel being open on the side away from the center of the bucket so that the bucket may swing from the position shown in full lines in Fig. 1 to the position shown by the dotted lines, the lower edge of the bucket being cut away as at 16 so that it may pass over the members 2.
The knife 5 is extended slightly beyond the diameter of the bucket so that the hole will be bored slightly larger than the bucket to the end that the bucket may be easily removed from the hole.
The operation of the device is as follows: After the tool has been attached to the auger shaft 17, the latter is set in motion and-fed downwardly until a depth of hole has been bored which approximately fills the bucket whereupon the auger shaft and the tool are elevated until the collar 13 comes in contact with the lower face of the bearing 3 1 whereupon a further elevation of the auger shaft raises the pivotal connection 10 and swings the bucket 8 to the dotted position of Fig. 1, the auger shafts meanwhile continuing its rotation whereupon the contents of the bucket are discharged and scattered in a circle around the hole and at sufficient distance from the edges thereof to prevent any of the dirt from falling back into the hole.
Upon lowering the auger shaft, the spring A overcomes the centrifugal force oi the bucket, and restores it to Working); position, a continued lowering of the auger shaft replacing the bucket in the hole and carrying it down to bring the knife into action to again fill the bucket.
The disk. 3 being of full area except Where it is cut away for the knife, raises all of the contents ot the bucket out of the hole when the auger shaft is elevated.
Having thus fully described my invention, I claim:
Ii. In an earth bori tool the con'ibination of knife carrying name, and a bucket mounted thereon to swing laterally to die;- charging position.
2. in an earth boring tool the combina tion of a bucket, a knife carrying frame at one side of the bucket, a knife carried by the frame, and means for moving the bucket.
3. In an earth boring; tool the combination of a bucket arovided with achannel. a knife carrying frame missing through the channel and carrying a closure (llSK, and means for moving the bucket to discharging position.
4,. In an earth boring tool the combination of a frame, a closure disk carried thereby at the lower end thereof a kui l'o ca ried by the closure disk a swinging bucket carried by the frame near the upper end thereof and means "for swinging the bucket to discharging position.
5. In earth boring tool the combination of an auger shaft, a frame carried thereby, a closure disk carried by the frame, a knife. a bucket carried by the frame and mounted to swing thereon, a collar mounted to slide on the auger shaft, :1 llG/lllll il nrunber 'l'orniing an abutment to move the collar and a link. from the collar to the bucket whereby when the device is raised the bucket will be moved to dis-barging position.
6. ln an earth boring); tool the combination of an auger shalt, a frame carried thereby, a closure disk carried by the frame, a knife, a bucket carried by the :i'rame and mounted to swing; thereon, a collar mounted to slide on the auger shaft, a bear-in; member forming an abutment to more the collar, a link from the collar to the bucket whereby when the device is raised the bucket will be moved. to discharging position, and a spring; for restoring the bucket to leading position.
