Surrounding the front edge of the bucket below thecheeks 11,1-11, I provide amouthpiece or cutting lip 28 formed of aplateof ,relatively high abrasive-resisting qualities, preferably steel, said plate being over and connected to the corner pieces 26, 26 and side -walls 13 by rivets 29, 29, and also being connected to the bottom wall by rivets 30, 30. vIt will be observedin Figure 6, that the upper'surface-cfthefmouthpiece plate is rabbeted with a rearward facing shoulder 28a so as to receive the ,forward margin of the bottom plate with 'theupper surfaces of both plates flush. ffii fi A ller plate 32 is interposed below the bottom plate and withinithe :rabbetedwpor-tion vof 4the mouthpiece plate, 'said'v `filler plate vextending transversely between 'theliinnerfpposed edges of the corner pieces 26, .26"as-is'bestshownin-Figu1'e5-5and 6, i'l
'A plurality of forwardly projecting- dipperteeth 35, 3 5 are mounted alongthe `cutting vlipof the bucket, in the form shown said dipper teeth'each having a base formed -of upper and lower forked legs 36, 37, respectively, fitting/over the front 'edge of the mouthpiece plate 28. "The two intermediate teeth, o neof which is shown in enlarged detail in Figure', each have their upper leg 36 overlying the front margin of the bottom plate 25, `and theirconnecting rivets-30, 'ex-'- tendv through said upperimargin'of vthe bottom plate, the rfiller plate 32, the mouthpiece plate 28, and the lower leg 37 ofthe tooth. The outer pairl of teeth are similarlysecured by.rivets, exceptingthat said teethpreferably register with andare riveted tothe lower rabbeted margins 26 ofthe corner pieces 26, asshown in VFigure 5.
r I also provide a pluralityofskids`40, 41 extending longitudinallyfalong the bottom Vand partway up the rear wall, said skids being preferably connected in longitudinal'alignment with each of the teeth 35, v and the outermost 'pai-r of f- skids 40, 40 beingriveted at the adjacent overlapping joints of the bottom plate 25 and Icorner piece 26, while vthe two central skids 41,' 41" are riveted directly to the curved bottom platev 25. 1
The arch structure-10 is made up of a plurality of rplates and reinforcing strips `which ywill'now befde'scribed n detail. Y
Overlying the outer sides of the side plates 13% at the cheekportions 11,11 of thefbucket, 'is an inner arch plate 42s (See Figs. 2 and 3.) The upright lowerportions 4 3, 4 3 of `saidinner arch plate extend downwardly and rearwardly from the front ofthe bucketjso'as to lap the upper margins 28eo'f the mouthpiece plate '28, and are connected thereto by a pluralityof rivets 44, 44 which also pass through the sideplates 13E., 13a `as shown in Figures 1, 2 land 5. The side or cheek portions`43 of said inner arch platev which overlap the side plates, 13?? are therefore wider longitudinally. kOfthejbuc'zket than the upper transversely, curved portion ofthefarch structure, as is best seen in vFigure 1.
Aplurality of reinforcing strips or bars are carried upwardly and, across the arch structure lust.Outsidefpthe:inner argh plete, 42. the
form s hownthree rows of such reinforcingstrips beingemploye@,eahrow consis' 'g'pfa flat bar 45 of uniformfth'ickness'-'throughut'ts length,
and a superimposed bar 46 which is substantially thicker overthe topof the arch structure and tapered downwardly along the sides of said structure as clearly shown in Figure 4. Another similar set of reinforcing bars 45a, 46EL is disposed along each rear margin of the inner arch plate where it joins the side plates 13, as is best seen in Figuresv land 5. r Y
An outer arch plate 47 extends over the top of the arch structure in direct engagement with 4. the tapered reinforcing strips 46 and 46a. This outer arch plate is of substantially the same pattern as the inner arch plate 42, excepting that theupright lower portions thereof extend downwardlyL only to,` but not lapping the mouthpiece plate 28, as is clearly shown in Figures 1, 2 and 5. Incorporated alsoV in this arch structure are the draglineA connecting brackets 18, 18 at the frontofeach cheek portion 11. These brackets are interposed longitudinally between the outer and inner arch vplates'42 and '47,'and are 'securely connectedthereto by a' plurality of .through rivetsr48, which rivetsalso extend through the adjacent portions of .the side plates as is best seen in'Figure 2. With this construction it will be observed that the brackets are fully housed between the arch plates so that the connecting rivetsare in double shear, thus providing an extremely rigid and secure connection at these points.4 Y
VIt will be seen also in Figure 1 thata reinforcing plate 50 extends forwardly and horizontally from each of the trunnion supports 21, 21 along its respective side plate 13a, and each reinforcing plate is offset outwardly'at its forward end so as to overlie the adjacent inner arch plate 42 and with its forward end abutting the adjacent dragline bracket 18. A filler plate 51 is interposed between the outer arch plate 4'7 and therhorizontal reinforcing plate 50, as isalso shown in Figure 5. All of theparts just mentioned are secured4 together by a pluralityof through rivets 54, which also extend through the side plates 13a. y The upper margins of the side and rear walls 12 and14 are also reinforced by strips '55 'which may also be of aluminum, riveted along the inner edge thereof. As an added protection against abrasion'and wear`of the dump line connections, I also providea pair of inverted L-shaped angle steels'trips 56 'along the outer 'and top edge of the side plates, as shown in Figure 7. From the above description, it will n ow be seen that when riveted together, the draglne bracket 18, the inner and outer arch plates 42 and 47, and the upper Amargins 28a'of the mouthpiece plate 28 are all secured to eachother and to the adjacent side plates -13afof the bucket,vthus makingran extremely rigid and strongly reinforced framework, which framework is further extended downwardly to include the corner pieces 26, 26 'through the mouthpiece plate 28, and is also extended rearwardly to the trunnion supports' 21 through the horizontal reinforcing plates 50.
With, the construction above described, it is possible'to form the side plates 13a and the bottom and rear plate 25 of sheet'metal which is considerably thinner than `heretofore employed in buckets of the character described, whereby the entire bucket is lighter in weight, and yet so reinforced by the heavier framework `members described that itis more substantial than buckets lof the vusual type having relatively thick and heavy sectioned walls throughout its structure. 'v More especially I find itpossible to construct the major portion'of my improved form of bucket out of aluminum"V or, a similar relatively light metal, so that the bucket is considerably lighter than steel buckets heretofore employed. In addition to its lightness the strength due to the reinforced vstructure makes it even more substantial than .the customary bucket built of steel. Its lightness makes it possible to increase thecapacity of the bucket for a given load-pulling capacity idly and completely than is the case with ordinary all-steel buckets. i i
. Although I have illustrated and described one particular embodiment of my invention, it will be understood that I do not wish to be limited to the exact construction shown and described, but that various changes and modifications may be made without departing from the spirit and scope K of my invention.
I claim:
1. A dragline bucket having bottom, rear and side walls formed of sheet metal, and a reinforcing framework including continuous corner pieces extending along the lower and rear corners of said bucket and connecting said side walls with said bottom and rear `walls throughout their length, and a mouthpiece plate connected between said corner piecesand extending transversely across the front margin of said bottom wall to form the cutting lip of said bucket.
