Definitions

  • Objects of my invention are to obviate the disadvantages of the old practice and to provide a lip that may be secured without the aid of rivets; is quickly and easily attachable and detachable;
  • Figure 1 is a longitudinal sectional view of a dredge bucket and lip assembly embodying the improvements.
  • Fig. 2 is a section on line 2-2 of Fig. 1.
  • Fig. 3 is a section on line 3-3 of Fig. 2.
  • Fig. 4 is a section on line 44 of Fig. 1.
  • Fig. .5 is a section on line 5-5 of Fig. 1;
  • Fig. 6 is a section on line 6-6 of Fig. 1.
  • lip 6 may have any desired form of cutting edge '7.
  • the hood with relation to its accommodation of the lip, is formed on the inside with fore and aft lip seating areas defined by shoulders 8, which forwardly vanish in the body of the hood and which rearwardly terminate in recesses or pockets 9, which establish a sort of hinge-like connection for the terminals of the lip and prevent spreading thereof.
  • the hood is equipped with paired ribs 10 whereby means are provided, which, in conjunction with the hinge lock, rigidly secures the lip to place.
  • the rounded terminals 17 of the lip enter the anchoring pockets 9 and thus hold down the rear of the lip and ,efiec-tively operate to prevent spreading thereof.
  • Figs. 4 and 5 aptly show how the hood and inside aprons have mutual rabbeted provisions to insure flush seating of the lip and thereby the avoidance of conditions making for choking.
  • the frontof the lip is formed with depending lugs 18 to fit between the ribs 10; and the ribs and lugs have registered eyes to accommodate a taper pin or bolt 19.
  • Reasonable clearance is allowed between the seating surfaces of the lip and bucket so that when the taper or wedge fastening is applied a rigid fit is established.
  • a chain dredge bucket having a lip seat, in combination with a separable lip, means on the bucket and cooperating means on the lip and relatively engageable so that the lip may be supported on its end extremities in upraised position and then eased through a circumscribed arc to seating position, and means for securing the lip in operative relation with the bucket.
  • a chain dredge bucket embodying a hood formed with sockets constituting hinge elements for a straddling lip, and a lip having terminals formed in coincidence with said sockets and engageable therewith to permit the lip to be rocked through a circumscribed arc to or from straddling relation with the hood, and means for securing the lip in efiective seating relation.
  • a chain dredge bucket having a hood formed with a lip seat and with sockets below and extending rearwardly of the lip seat and constituting hinge elements fora lip, and a lip having terminals formed in coincidence with said sockets and engageable therewith whereby the lip may be rocked through a circumscribed arc to or from straddling relation with the hood, means for centering the lip, and means for securing it in quickly detachable relation.
  • a chain dredge bucket whereof the hood is kept up to maximum cubic capacity by a lip having inside and outside straddling portions, the hood having inside rabbeted areas to insure flush seating of the inside straddling portions and which merge into pockets, and a lip of the type recited having terminals adapted and arranged to be cradled in such pockets whereby the lip may be readily swung to or from straddling position, and means for securing the lip.
  • a chain dredge bucket whereof the hood is kept up to maximum cubic capacity by a lip having inside and outside straddling portions, the hood having inside rabbeted areas to insure flush seating of the inside straddling portions and which merge into pockets, and a lip of the type recited having terminals adapted and arranged to be cradled in such pockets whereby the lip may be readily swung to or from straddling position, the outside straddling portion and the hood having cooperative guides for centering the lip.
  • a chain dredge bucket whereof the hood is kept up to maximum cubic capacity by a lip having inside and outside straddling portions, the hood having inside rabbeted areas to insure flush seating of the inside straddling portions and which merge into pockets, and a lip of the type recited having terminals adapted and arranged to be cradled in such pockets whereby the lip may be readily swung to or from straddling position, the outside straddling portion and the hood having cooperative guides for centering the lip, and means whereby said guides may be availed of to secure the lip in quickly detachable relation.
  • a chain dredgebucket having a hood formed with a lip seat and with cored pockets below and beyond the lip seat and having outwardly flaring top walls and constituting one element of a hinge connection for a straddling lip.
  • a chain dredge bucket formed inside with downwardly curved rabbeted areas terminating 'rearwardly in cored pockets adapted to receive a lip of the swinging type.
  • a chain dredge bucket having a lip seat with rabbeted areas inwardly thereof to provide for substantial fiushseating of a straddling lip and having undercut outwardly flaring pockets to receive swingingly the ends of the lip, and lip 'centering and locking devices formed externally of the bucket.
  • a lip formed with a hood seat defined by spaced apron extensions, said lip having centering and locking devices of the quickly releasable,
  • the terminals of the lip having blunt noses constituting pivots.
  • a dredge bucket having a lip seat and provided externally with abutments and internally with pockets having rounded bottoms, and a lip having end extensions fulcrumed in said pockets and having apron extensions within and without the bucket and having a part engageable with the abutments.
  • a dredge bucket having a rim seat adapted and arranged for the reception of a straddling p and having below the rim seat undercut pockets constituting hinge elements for the lip, and a lip adapted to the seat and having outside apron extensions and having inside apron extensions substantially fiush seated with the inside wall of the bucket, said lip having blunt nose terminals to establish hinge connection with said pockets), and means externally of the pocket and lip for securing them in quickly detachable relation.
  • a dredge bucket having a rim seat adapted and arranged for the reception of a straddling lip and having below the rim seat undercut pockets constituting hinge elements for the lip, and a lip adapted to the seat and having outside apron extensions and having inside apron extensions substantially flush seated with the inside wall of the bucket, said lip having blunt nose terminals to establish hinge connection with said pockets, and means on the front of the bucket to tighten the lip in normal posturing relation.
  • a chain-dredge bucket in combination with a straddling lip having aprons which respectively lap the inside and outside walls of the bucket, the inside wall-of the bucket and the ends of the lip having mated bearings providing for tiltable mounting of the lip so that it may be applied or removed by rocking it through a circumscribed arc, and interlocking provisions for the bucket and lip, including means for tightening, the'lip.
  • a chain dredge bucket having its rim and inside wall portions formed to accommodate a replaceable lip, alip contoured to fit the edge of thebucket and having inside and outside bucket lapping portions, means on the bucket and cooperating means on the lip'and relatively engageable so that the lip may be initially supported in upraised position and then eased through a circumscribed arc to proper seating relation with the bucket whereupon said meanson the bucket and the cooperating means function as an end lock for the lip, and means for taking up relative looseness.
  • a chain dredge bucket having lip seating areas for cooperation with a replaceable lip
  • pivot members on the bucket and cooperating pivot members on the lip relatively engageable so that the lip may be sustained on end in uplifted position and then swung downwardly to its seat whereupon said pivot members function as end locks for the lip, and cooperating means on the lip and bucket for compensating for relative looseness of fit.
  • a dredge bucket comprising a hood having a rim seat and bearing surfaces below the same for the swinging mounting of a lip, and a lip having terminals engageable with said bearing surfaces to permit itto be moved through a cir-' cumscribed are into straddling relation with the run.
