EX'GAVATING AND HOISTING BUCKET.

SPECIFICATION forming part of Letters Patent No. 528,579, dated November 6, 1894.

Application filed December 11, 1893. Serial No.493,374. (No model.)

To @ZZ whom it may concern:

Be it known that I, GURDoN H. WILLIAMS, of Brighton, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Excavating and Hoisting Buckets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in excavating and hoisting-buckets, and it consists in certain features of construction, and in combinations of parts hereinafterdescribed and pointed out in the claims.

In the accompanying drawings,Figure lis a side elevation, mostly'in -central vertical section, of a bucket embodying my invention. Fig. 2 is a top plan of the same, portions being broken away and iu section to more clearly show the construction. Fig. 3 is an enlarged side elevation in central vertical section on line 3--3, Fig. 2.

My invention pertains more especially to that variety of buckets that are composed of two or more sections that form the sides and bottom of the bucket with the sections pivotally supportedand arranged in such a manner that the sections, in hoisting and lowering the bucket and in conveying thesame from place to place, will be held closed together, and are capable of being swung outwardly upon. their pivotal bearing to separate them and thereby open the bucket.

My present invention consists more especially in the means employed for operatively4 connecting the pivotal sections of the bucket with the hoisting-rope in such a manner that the construction is lrendered assimple and durable as possible without liability of the bucket being opened during the hoisting and when closed together, as shown in Figs. l and 2, form the sides and bottom of the bucketpropel'. Each section A, in the case illustrated, is provided, at its upper and central as, and an inwardly-extending and centrallylocated arm, 0,4, the former, at its outer eX- tremity,l being operatively connected, by means of a link, B, with the lower portion of a tubular member C, that is located at the top and centrally of the bucket, and has attached, at its upper extremity, the hoistingrope or cable D, and arm a, at its inner eX- tremity, is pivotally connected to a sleeve, E, that easily'embraces member O, said sleeve being enlarged diametrically at itslower end, as at E', and arms a4 of plates a of the bucketsections being pivoted to one or more lugs or ears projecting laterally and outwardly from the lower extremity of 'said enlarged portion of sleeve E. Links B are connected with member C below the upper extremity of the enlarged portion E ofisleeve E, the same being pivoted preferably, as shown, to one or more laterally-projecting lugs or ears on member O, and the enlarged portion of sleeve E being slotted, as at E2, toaccommodate the locationl and operation ot' said links. Plates a, preferably at or near the inner extremities of arms a4, are' operatively connected, respectively, by means of one or more links G, with a sleeve, H, easily embracing sleeve E, a pair of links G being preferably employed for each bucket-section and said links being preferably pivoted to a laterally-projecting lug or ear at or near the upper end of sleeve H. Sleeve H, lat its upper extremity, is also provided with a laterally-projecting lug or ear h that has attached an upwardly-extending rope or cable I. l v

I would here remark that both ropes or cables D and I are connected with windingdrums (not shown) and lead from their con- IOO- already indicated, with the lower extremity of sleeves Eand operatively connected by means of links B with the hoisting-cable engaging member C and carry the sections that form the bucket-proper.

The arrangement of parts is such that upon releasing the hoisting rope or cable or permitting the same to be paid out and placing a draft upon rope or cable I, member C, links zo B, levers a., d3, a4, and attached bucket-sections shall be actuated in the direction to effect the separation of the bucket-sections, thereby opening the bucket or placing the same in condition to take up or discharge its load, as shown in dotted lines Fig. 1, and that by releasing or permitting rope or cable I to pay out, and. causing the draft to be on the hoisting-rope or cable, the parts of the bucket just referred to will assume the position shown in solid lines in the drawings, as required preparatory to the hoisting and conveyance of the load, the upper end of the enlarged portion E of member E` forming a stop to limit the elevation of the hoisting-ropeengaging-member independently of the other parts of the bucket.

I would also remark that sleeve H, at its lower end, has attached one or more ropes, chains or cables K (see Fig. 3) that lead thence downwardly to and over sheaves K suitably supported within the enlarged portion E of sleeve E and thence upwardly a suitable distance into member C, to which the chains or cables K are connected, as at K2, member C and the enlarged portion E of sleeve E, being slotted, as at C and E3, respectively, to accommodate the location and operation of said chains or cables.

By the construction thus described, it Will be observed that chains or cables K assist in the operations of opening and closing the bucket.

l. In a bucket of the variety indicated, the 45 combination with the sections that form the sides and bottom of the bucket-proper, of a reciprocating hoisting-cable-engaging-member located at the top and centrally of the bucket, a sleeve or tubular member E embracing vsaid hoisting-cable engaging-member, levers rigid with the aforesaid bucketsections and pivotally connected to the lower end of the aforesaid sleeve,links operatively connecting said levers with the hoisting-ca- 55 ble engaging-member, and suitable means operatively connected with the bucket-sec` tions for actuating the latter to separate or open, substantially as set forth.

2. In a bucket of the variety indicated, the

5o combination with the sections thatform the sides and bottom of the bucketproper,of a reciprocating hoisting-cableengagingmern ber located at the top and centrally of the bucket, a sleeve or tubular member E embracing said hoisting-cable-engaging-member, said sleeve being enlarged diametrically at its lower end, a plate a secured to each of the aforesaid bucket-sections, said plates having, respectively, an upwardly-extending arm as and an inwardly-extending arm a4, the lat- 7o ter being pivotally connected to the lower end of the aforesaid sleeve, links operatively connecting arms a3 of said plates with the hoisting-cable-engagingmember, and suitable means operatively connected with said plates at or near the inner extremity of the inwardly-extending arms of the plates for actuating the aforesaid bucket-sections to separate or open, and the aforesaid sleeve being slotted to accommodate the location and op- 8o eration of the aforesaid links, substantially as set forth.

3. In abucket of the variety indicated, the combination of the sections that form the sides and bottom of the bucket-proper, said sections being adapted to separate and thereby open ther bucket; a relatively stationary member E; levers, a a3 a4,fnlcrumed to said stationary member, 'and rigidly secured 4to the aforesaid bucket-sections; a reciprocating hoistingcable-engaging-member and links B operatively connecting the `aforesaid levers with said hoisting-cable-engaging-mem ber; another reciprocating member H and means operatively connecting the same with the bucket-sections; a rope or cable attached to said member H for elevating the latter, and one or more chains or cables attached at opposite ends to the aforesaid two reciprocating-members, respectively, the arrangement roo of parts being substantially as and for the purpose set forth.

4. In a bucket of the varietyindicated, the combination of the sections that form the sides and bottomof the bucket-proper; memx05 ber E enlarged at its lower end, as at E', and slotted, as at E2, E3; hoisting-cable; inner reciprocatingmember C having laterally-projecting lugs C; levers a a3 a4; links B; outer reciprocating-sleeve, I-I; cable I; links G; one 11o or more chains or cables K, and sheaves or guides K', all arranged and operating substantially as shown, for the purpose specified.

In testimony whereof I sign this specification, in the presence of two witnesses, this 18th day of November, 1893.

GURDON H. WILLIAMS.
