Description
March 24, G R H NK CHAIN DREDGE BUCKET AND LIP THEREFOR Filed Au 5, 1954 5. Hanks Patented Mar. 24, 1936 CHAIN DBEDGE BUCKET AND LIP THER EFOR
George R. Hanks, Clinton, N. J., assignor to I Taylor-Wharton Iron & SteelCompany, High Bridge, N. J., a corporation of New Jersey ApplicationAugust s, 1934, Serial No. 738,371
Claims. (01. 37-141) f The invention relates to chain dredge buckets and provides certain improvements in the assembly of the bucket and lip.
In certain prior applications of William H.
5 Stires there is disclosed a chain dredge bucket and lip assembly in which a lip of the insideoutside apron type is cradled with relation to the bucket whereby it readily may be swung through a circumscribed arc to correct seating relation and thereafter secured by a quick-acting interlock. The cradling is accomplished through the instrumentality of cored pockets or of trunnions cast integral with the hood of the bucket and which serve as pivotal mountings for the ends of the lip.
My improvements are directed to the proposition of providing a swinging or pivotal mounting for the lip which shall be entirely independent of the bucket thereby obviating certain foundry problems incident to the provision of mountings including parts formed integral with the bucket.
The nature, characteristic features and scope of the invention more readily will be understood from the following detailed description taken in 5 connection with the accompanyi drawing,
forming a part hereof, wherein:-
Figure 1 is a view principally in section of a chain dredge bucket constructed in accordance with my improvements.
Fig. 2 is a top elevational view, the middle link being in section more clearly to disclose the pivotal relation of the lip and pin.
Fig. 3 is a detail of the interlock.
Fig. 4 is a section on line 4-4 of Fig. 1.
Fig. 5 is a sectional detail of a modification in which the lip ends are pivotally mounted on the bucket pin externally of the paired links.
Referring to the drawing 5 represents one of a series of chain dredge buckets having, as usual,
a single front eye or linkage member 6 with a pair of rearwardly extending eyes or linkage members 1, the latter cooperating with a pin 8 to secure in linkage relation the front eye 9 of the next adjacent bucket.
The lip I0 is of the inside-outside apron type,
that is to say, it has inside lapping or apron extensions ll and outside lapping or apron extensions l2. The rim of the bucket may have a straight edge IS in consonance with the straddling portion of the lip and the inside aprons ll may also have a simple straight edge I4 in consonance with that t half or abutment I5 on the in- The free ends I! of the lip are downwardly extended over the back wall of the bucket and terminate in collars l8 which are accommodated between the paired eyes I and the connecting eye 6, the parts being secured in the assembly 5 stated by the bucket pin 8. As thus described, the lip has a swinging or pivotal mounting with relation to the bucket pin whereby it may be moved to straddling relation with the rim and secured against lost motion by a front lock 10 preferably of the wedge type, so as to take care of any looseness, and which may be exemplified as by a taper key or bolt I9 cooperating with lapped lugs 20 and 2| formed, respectively, on the lip and bucket and having registering eyes 15 to accommodate the taper bolt.
The parts 22 are digging or breaker teeth. Their showing is purely incidental and they are not essential to the successful practice of the invention. 20
In the modification, Fig. 5, the lip eyes or collars 23 engage the pin 8,.as before, but externally of the paired eyes of the bucket, being retained on the pin by end thrust provisions such as the loose ring 24 and a cotter pin 25. This arrangement 5 simplifies the removal of the lip when such becomes necessary and it has the further merit that it provides adequate means to prevent casual displacement of the pin.
Having described the invention, what is claimed 0 1. A chain dredge bucket having shoulders forming inside lip bearings and a linkage pin, and a lip conformable to said bearings and having parts extending over'the rear wall of the bucket 35 and mounted for swinging movement on said pir. towards and away from the bearings.
-2. A chain dredge bucket having inside lip boarings formed as shouldered offsets inwardly of the rim and substantially parallel therewith, a 40 linkage pin, and a lip conformable to said bearing and having parts extending over the rear wall of the bucket and mounted for swinging movement on said pin whereby the lip may be pivoted towards and away from seating position. 45
3. A chain dredge bucket including a hood having an inside lip stop and a lip flush seated within the hood and movable with relation to the stop, the hood having bearings for a linkage pin, and the lip having arms extending over the back wall 50 of the hood and engaging the linkage pin and constituting rocking members for the lip.
4. The combination with the hood and linkage pin of a chain dredge bucket, of a separate lip shaped to conform to the shape of the hood and adapted to be flush seated within the mouth of the hood and having arms extending beyond the back wall 01. the hood and pivotally mounted on the linkage pin, the pivotal connection being between the pin bearings whereby the lip is restrained from spreading when under working stress.
5. A non-choking chain dredge bucket having inside straight edge shelves formed on a gradient and outside latch members, a lip constructed to straddle the rim of the bucket and having outside aprons and latch members cooperating with the first-mentioned latch members and inside aprons which snugly fit the shelves, lip extensions over and downwardly of the back wall of the bucket, and a member spaced from the back wall on which said lip extensions are rotatively mounted to permit the lip to be swung towards or away from straddling position.
