BUCKET ron EXCAVATORS.
Application filed March 24, 1924. Serial No. 701,465.
To all whom it may concern.
Be it known that I, lVALrnn BAKER, a
citizen of the United States, and a residentv of Fairfield, in the county of Jefferson, State of Iowa, have invented a certain new and useful Bucket for Excavators, of which the following is aspecification.
This invention relates to improvements in buckets for excavators.
The object of my invention is to provide an excavator bucket of rigid,si1nple, durable and inexpensive construction.
A further object is to provide in connection with an excavator bucket improved means for hitching and supporting the bucket so that it may be manually controlled from an excavator when the bucket is at a point remote therefrom, both for filling and emptying.
My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawin s in which:
Figure 1 is aside elevation of my improved bucket having a portion of one corner broken away to show the cutting blade.
Figure 2 is a plan View of my improved bucket.
Figure 3 is a front end view; and
F i gure t illustrates the shape of the blank of which the body portion of my improved bucket is formed.
The main body portion of my improved bucket is formed of a single piece of sheet metal which is blanked into the shape shown in Figure 4, and formed sub stantially rectangular having top edges 11, a front edge 12 and a back top edge 13. The corners between the edges 11 and 13 are provided with notches 14. The edges of said notches are curved as illustrated so that the body portion may be pressed into the shape illustrated in the assembled drawings.
The sides are diverged outwardly and the bottom downwardly so that the front end of the bucket is larger than the back end.
This provides means whereby clearance is provided for the outside surfaces of the sides and bottom members as the bucket is being advanced into material while being filled. This also provides means whereby the bucket may be more readily emptied and placed in a dumping position.
The edgesof the notches 1e are formed in shape so that they rest adjacent to each other, after which they are welded by the autogenous method. The top edges are provided with a U-shaped band 17 secured to the top edges by means of rivets 18. The said band extends outside of each of the top edges and outside of the back member, the ends of the band, extending forwardly and beyond the front edgesof the bucket, as clearly illustrated in Figure 1. The forwardly extending ends are connected together by means of a transversely arranged plate 19 having its end 20 extending downwardly and deiigned to rest adjacent to the outer faces of the forwardly extending portions of the band 17, and secured in position theretoby means of rivets 21.
By providing the member 19 with downwardly extending portions 20 I. have formed a sort of arch which serves the purpose of rigidly supporting the forward side edges of the bucket against spreading laterally, and at the same time provides an opening for the forward end of the bucket, through which a large amount of dirt may enter. This also provides means for permitting the bucket to be quickly emptied. The arch member 19 also serves the purpose of loading the forward edge of the bucket so to give it a suction and cause it to be easily and quickly filled by simply pulling the bucket forwardly by means of the draw chains 22 connected to the front ends of the I member 17 by a clevis 23. j
The inclined bottom portion 15, together with the weighted arch 19 forms means whereby when the bucket is drawn forwardly by the chain 22, it will have a considerable tendency to pull into the earth, and the filling can be controlled by means of supporting chains'2t secured to a clevis 25 in the back portion of the member 17. The chains 24 are suspended from a cable 26 which extends to a drum provided for that purpose on the excavator.
The clevis 23 is adjustably mounted in the forward end of the member 17 by means of a series of vertically arranged openings 27 and the clevis pins 28. The entire weight of the bucket when either filled or empty is carried by means of chains 29 and 80.
edges of the member 17 at a point near the front end of the bucket by meansof clevis 31, the clevis pins 32 of which may be secured in any one of a series of openings arranged in a row parallel with the top edge of the bucket. This provides means whereby the center of gravity of the bucket may be changed to meet the conditions of different kinds of material which the bucket is designed to handle. If the bucket is being operated in loose sandy material, the tendency is for the load to move toward the back, and if the bucket is handling damp and sticky material, the load will stop at a point close 'to the front end. The back end of the bucket is balanced by means of the rearwardly and downwardly extending chain 50.
The chains 29 and 30 are so arranged that when the bucket is loaded, they will be suspended by the cable 34, When the bucket is in an elevated position-the cable 2'6 and the chains 24 only serve to dump the bucket by elevating the rear end or to assist in filling it.
Thus it will be seen that I have provided a bucket of simple, durable and inexpensive construction which is very rigid an; which is so shaped and formed that it may be automatically filled by being moved to a position where the forward edge of the downwardly extending portion 15 will engage the ground surface, then moving the chain 22 forwardly. The overhanging weight of the member 19 has a tendencyto force the bucket into the ground. The filling tendency or suction of the bucket is further assisted by slightly elevating the chain 26, if so desired.
It will be seen been filled and dirt is in the back end of the bucket, if the cable 26 is released and the cable 3d elevated, then the bucket may be moved directly upwardly to disengage the surface of the ground, and the filling operation discontinued. I
I claim as my invention:
1. An excavator bucket comprising a body that when the bucket has portion having a bottom, a back and side members, a band extending around the top edge of said bucket having forwardly extending ends, means for securing said band to said bucket, an arch member for supporting said forwardly extending portions against lateral movement, the forward ends of said forwardly extending portions of said band being provided with a series of openings arranged in a vertical line, the central portion of the side of said band being pro vided with a series of openings arranged in substantially horizontal plane, a clevis detachably secured with each set of the first said openings, at clcvis for each set of the second said openings, a chain for the first said clevis, and a chain for the second said clevis, a third chain in connection-with the second said chain mounted on the rear end of said bucket, and a tilting chain secured to the back edge of said bucket.
2. An excavator bucket comprising a body portion formed of a single sheet of metal having its forward bottom edge and its side edges liared outwardly, a band extending around the top edge of said bucket having forwardly extending ends, means for securing said band to said bucket, an arch member for supporting the said forwardly extending portions against lateral movement, the forward ends of said forwardly extending portions of the said band being provided witha series of openings arranged in a vertical line, the central portion of the side of said band being provided with a series of openings arranged in a substantially horizontal plane, a clevis detachably secured with the first said openings a d a clevis for the second said opening, a chain for the first said clevis and a chain for the second said cicvi a third chain in connection with the second said chain mounted to the rear end of said bucket, and a tilting chain secured to the back edge of saidbucket.
