To allwkom itmtty concern:

Be it known that I, ERNEST H. FALLEN- STEIN, a citizen of the United States, residing at Mankato, in the county of Blue Earth and State of Minnesota, have invented a new and useful Cableway Excavating- Bucket, of which the following is a speci fication.

This invention relates to excavating buckets, and more particularly to an excavating bucket designed to move over a cable,- way, it being the primary object of the invention to provide means for locking-the bucket against pivotal movement with respect to its bail to eliminate any possibility of the bucket dumping while the same is carrying its load.

A further object of the invention is to provide means controlled by the dumping cable to unlock the bucket and permit the same to readily dump its contents.

A still further object of the invention is to provide a lock which will be held in operation by the weight of the contents of the bucket, associated therewith.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings Figure 1 illustrates a side elevational View of a bucket constructed in accordance with the present invention and showing the same in its locked position.

Fig. 2 illustrates a side elevational view of the bucket showing the same in an unlocked position.

Fig. 3 illustrates a perspective view of the bucket in its locked position.

Fig. 4 illustrates a rear elevational view of the bucket and Fig. 5 illustrates a view showing the bucket on its supporting cables.

Referring to the drawings in detail, the bucket comprises a support embodying opposed legs 5 and 6, which are formed at their upper ends with inwardly extending portions to provide a bail 7 the extreme upper ends being connected as by means of type and includes opposed bearing members 13, which bearing members receive the pivot pins 14 for securing the pins to the support.

As shown, these bearing members 13 are disposed in spaced relation with the opposed legs of the supporting bail to provide a. clearance for the ends of the locking bail 15, which forms an important feature of the present invention, the locking bail being however pivotally mounted on the pins let.

The bucket indicated at 16 is supported between the opposed legs of the auxiliary bail 9, to move therebetween, the pivot point p of the bucket 16 being adjacent to the forward extremity of the bucket to permit the bucket to tilt rearwardly under the weight of its load.

Extending laterally from the bucket walls are the bolts 17 that are disposed adjacent to the upper rear corners of the buckets, which bolts provide bearings for the rollers 18, which are designed to move in the cut out portions 19 of the locking hail, the cut out portions being provided with right angled extremities providing seats for the rollers 18, when the bail 15 is in its locking position.

An operating cable 20 has connection with the locking bail 15 as through the links 21, which operating cable passes over the roller 21' mounted between the side walls of the carriage 22 from where the same passes over the pulley 21 which is supported by the cable standard 23.

The bridle cable 24. connects with the bucket 16 through the pivoted arms 25 which are mounted on the supporting bolts 26 that connect the bucket 16 to its support, and this bridle cable 24 is wound on a suitable drum not shown, whereby the bucket may be forced into a sand or gravel pile, to cause the bucket to pick up a quantity thereof.

From the foregoing it will be seen that as the forward portion of the bucket 16'is drawn toward the material to be scooped thereby, the weight of the material passing into the bucket, tilts the same rearwardly, causing the rollers to move in the slotted trackway or cut out portion 19 until the same seat themselves in the right angled portions of the trac-kways with the result that the bucket 16 is locked in its carrying position.

' WVhen the bucket has been moved to a 10 cation where the same may bedumped, the

operating cable 20 is moved to release the locking bail 15, whereupon the load or contents of the bucket may be deposited. It might be further stated however that a plurality of teeth 27 are carried at the forward extremity of the bucket, to cause the bucket to readily penetrate a sand or gravel facilitate the loading of the bucket.

While I have shown the bucket as supported on suitable cables, it is to be under-- stood that I have not gone into thedetails of this construction, since the essence of the'invention resides in the bucket locking feature.

Having thus described the invention, what I claim as new is 1. An excavatlng bucket lncluding a suppile to I port, a bucket section pivotally mounted within the support, rollers carried by the bucket section, a locking bail associated with I the bucket section, said locking bail having slotted trackways to accommodate the rollers, said trackW-ays having right angle porfor operating the locking bail to release the bucket.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses. V
