' This is a'continuation in part of my api ets are constructed and arranged to rest on' ythe ground below the charging opening of Y the mixer so as to receive the aggregates to be mixed from barrows or shovels, or any other manner, near the lground level. The bucket is usually so mounted that as it is raised it also tips or tilts andl discharges its load-into the mixer. Y A cable leading from a drum on the mixer trame to the bucket is commonly employed for elevating same. The 2o present improvements arey designed to yafford a better, connection between the cable and bucket, which equalizes the pull of the former and economizes the power required tol ele- 'vate the load. Y The improvementsare illustrated in the accompanying drawings, in which-d f Fig. 1 is a side elevation of a loading bucket with connected parts embodying my improveniente Fig. -2 'is a iront view of my cable connection member or bail;

Fig. 3 is a detail of the bail; and Fig. 4 is a plan viewof one end of thebail.

Y The skip or bucket 1 is adapted to'be raised or loweredby means of a cable 2 running over n ,sheaves 3 and connected with asuitable power device. lis an upright member o't the frame y j of the apparatus, mounted on a base 5, one

of said uprights being provided at each side of the mixer (not shown).

p A plate 6 with turned strengthening edges is pivoted at 7 in brackets 8 secured on the uprights 4; and extends across from one bracket to the other, and at 9 near the bottom of V 4s this pivoted plate, the bucket carrying frames are .pivoted These vframes consist of the k'converging arms 11 and 12 connected by the plate 10 to each other and to the pivot,-the1 brace 18 connecting their outer portions and l the widened outer-ends 19 and 20 secured to -for elevating same. rThese loaders or buck-' the upwardly extending portion of the loading bucket or skip 1. The inward movement ofthe pivote'dy plate 6 is limited by the stop 13 `on base 5 and the inward and upward movement of the bucket carrying frame is limited by contact betweentlie plate 6 at its upper Ypart near its edge and the stop 16 riveted at 17 to the outer portion of trame 11. As shown, the bucket 1 has a charging portionY 21 and a discharging portion 22 at an angle to each other.v

On each side of the bucket and near the top thereof is rigidly mounted a lug or ear 24 having apertures 25 in which are disposed the `trunnions 26. of a bail or bridge 23. rlhe latterfis thus pivotally connected with the bucket-.on each side so that there ris a certain amount of pivotal movement between the bail and bucket. As seen in Fig. .4, the bail comprises'beams riveted together having riveted 'betweentheir ends the trunnions 26. However,l may utilize any` other form of bail. Apertures 27 are provided in each side oi the bail, and, adj acentthereto, mounted between said beams, are sheaves 28, said sheaves being so positioned that their peiipheries are in alignment with said apertures 27. The cable 2 runs over a sheave 3 on one side of the frame at the top, through the bail 23 entering same at one side, through aperture 27, over sheave 28 and extending around under it and passing out ovei sheave 28 and aperture 27 at the other side. Thence the cable 2 runs over sheave 3 on,l the other side of the frame.

In elevating the bucket to charging position, the foregoing improvements equalize the pull of the cable on the bucket and also protects the cable against undue wear and injury or the deteriorating effect of exposure to the ground, as where it is run under the bucket. y

Where one or more pivots are employed in elevating a bucket, it frequently happens that the heavy load of aggregates unevenly distributed develop a torque in the bucket tending to bind; at said pivots and therefore kthis undesirable twisting of the bucket and also economizes vpower since the endless cable r.

threaded through the apertures inthe bail, in conjunction with pivots 24, enables the bucket at all times to automatically adjust itself and the load to swing in the arc of least 5 resistance. Other advantages of the cony structionwill beapparent to` those skilled in i Y rthe art. c What l claim is: r

l. A loader bucketrhaving` charging and discharging portions at an angle to each other and adapted to be raised and lowered in an arc, a bridge pivotally mounted on said charging portion and extending across same, said bridge having spaced apertures adapted to receive a hoisting cable and means on said A bridge aligned with saidy apertures for bearing said cable.

2. In a device of the character described, a hoisting cable, aloader bucket adapted to be elevated and lowered, a cable connection memberV disposed (over. andv operatively conv nected to said bucket, said member having spaced cable reeeivingmembers, said cable extending Vthroughsaid members with a por- 2.5 tion thereof extending in exposed position' f along said first named member.

3. A loader lbucket adapted to be elevated and lowered having a cable connection member operatively associated therewith, said member having spaced apertures adapted to receive a hoisting cable and removable bearings housed in said member and aligned with said apertures for bearing said cable.v

4. A loader bucket adapted to be elevated L and lowered having a cable connection member operatively associated therewith, said member `extending across said lbucket and comprising parallel members connected in spaced relation whereby a hoist Vcable may o pass therebetween, and spaced bearing membersdisposed between lsaid parallel members yfor bearing said cable.
