ATTORNEY ELLTSON EISWARD VANDERHOEF,
0F RUTH, NEVADA, ASSIGNOR TO AMERICAN MAN- GANESE'STEEL COMPANY, OF AUGUSTA, MAINE, A CORPORATION OF MAINE.
BAIL FOB; mPrEn-BUoxE'rs To all whom it may concern: Be it known that I, ELLISON EDWARD Vanounnoiir, a citizen of the United States, and a resident of Ruth, in the county of White Pine and State of Nevada, have made and invented certain new and useful Improvements in Bails for Dipper- Buckets, of whichthe following is a specification.
My invention relates to a bail such as is used in connection with dipper buckets.
It has .been the practice, heretofore, to form the dipper bail and the attaching clevis as separate parts, and to secure the two together by means of rivets, bolts, or other fastening means. The class of service in which these structures are employed and the lack of proper lubrication between the clevis and the clevis pin and pulley block, cause the clevis to loosen upon th bail, and in time to be completely separated and torn therefrom, and the lack of pioper lubrication between the clevis and clevls pin often results in excessive wear and: injury to the pulleyblock. I have overcome these diificulties by forming the 'clevis' or attachlng member as a part vof the dipper bail, and so arranging and designing the members that the lubricant with which the hoisting chain or cable is provided is utilized in maintaining the bearing between the attaching mem her and attaching member pin 1n a thoroughly lubricated and proper Working condition, the result being that the bailis ca-.
pable of rendering long and satisfactory service.
A further object is to provide a bail which can be economically manufactured.
Other objects and advantages will appear as the description proceeds, wherein it is to be understood that changes in the precise embodiment of the invention can be made within the scope of what is claimed without departing fromv the spirit thereof. The preferred embodiment of my invention is disclosed in the accompanying drawings, wherein: T
Figure l. is a view in front elevation of a dipper bail embodying the characteristic features of my invention, portions of the pulley block to which it is attached being illustrated; Fig. 2 is a verticalsectional view taken. on the line 25-9101 Fig. 1; Fig. 3 is a fragmental view "iii top plan of the central portion of the dipper bail Referring specifically to the several views,
I Specification of Letters Patent.
Application filed May 18, 1916. Serial No. 98,289.
. 9, i substantially Patented Dec. 5, 1916.
the bail body 5 is formed in the nature of va fabricated structure, and is provided at its center with two spaced flanges "7. These flanges project above the bail body and enlarge and form an integral attaching memher 8.
The attaching member 8 comprises a head cylindrical in outline, through which extends an opening or bore 10. The attaching member pin 11', which is carried by spaced attaching arms which project below the pulley block 12, extends through the bore or opening 10 in the cylindrical head and effects a rotatable bearing therewith. The head 9 of the attaching. member is connected to the bail body 6 by the flanges 7 and by a. web 14, the entire construction being such as to withstand the jars and shocks, severe strains and rough usage to which the bail will be necessarily exposed im service. The spaced attaching arms which project below the dipper block receive therebetween the cylindrical head of the attaching member, which is substantially equal in length to the spacing of the said attaching arms, whereby an efiicient joint between the attaching member and pulley block is obtained. In order that the bearing between the atwaching member pinandaittaching member may bemaintained in a thoroughly lubricated condition, the head is provided at its 'upper portion with a slot or opening 15, which communicates with the bore 10. The slot 15 is located in close proximity to the hoisting chain or cable 13, whichextends around the pulley block, and lies directly beneath the lowermost point thereof. The chain or hoisting cable is always covered-or coated with a lubricant, such as a heavy grease, which grease is deposited upon the head of the attaching member as the chain or cable is moved. The location ofthe slot with a slot extending through the top portion thereof and communicating with said bore.
2. The combination of a bail bod an attaching member carried thereby an including a bored head, a pulley attaching meniberpm carried thereby and extending through the opening in said attaching member head, a hoisting member extendingaround saidpulley block, said attaching member head provided' with an opening therei located adjacent said hoisting member and conununicatingmvith the bearing 15 head and said pin.
3. The combination of a dipper bail, an attaching member rigidly carried thereby, said attaching member provided with an opening extending therethrough, a slot extending through the top of said attaching member and communicating with said opening, and-a pulley block pivotally secured to said attaching member and located in close spaced attaching block frame, an.
between said attaching member proximity to the slot in the attaching mexnher and adapted thereto.
v 4. In combination, a pulley block with arms projecting therebelow, a dipper bail with an upwardly project ing attaching member formed integral there with, said attaching member including a cyto supply a lubricant lindrical head substantially equal in len h to the spacing of the attaching arms 0 said pulley block and fitting therebetv'veen, said attaching member and attaching arms of the pulley blocks provided with alined cylindrical openings, and a pin extending therethrough for the pivotal securement of the,
two.
