CLINTON n. SAGE AND'sAnU'EL B. ALGER, or Noawion, Yoan.
Letters Patent No. 109,764, dated November 29, 1870.
IMPROVEMENT IN EXCAVATORS.
The Schedule referred to in these Letters Patent and making part of the same.
B. ALGER., of Norwich, in the county oi Chcnango and State of N ew York, have invented a new and useful Improvement in Excavators; and we'do hereby declare that the following is a full, clear, and exact description thereof, which willenable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in whichlhe ligure is a side view of our improved excavator.
Our invention has for its object to furnish an improved excavator for making excavations for railroads and other purposes, and for dredging in shallow' or deep water, and'which shall be so constructed as to work at a distance from the frame ofthe machine and move the material to a distance when required, and
y which shall, at the same time, he simple in construction and easily and conveniently operated; and
It consists in the constructitm and combination ot' the various parts of the machine, as hereinafter more fully described.
A is the mast, 'the lower end of which should be secured to a turn-table in the usual manuel', said turntable being connected with a foundation-frame which maybe mounted upon wheels and which supports the machinery for operating the excavator.
lo the mast A, nea-r its lower e11d,is hinged or jointed the end ot' the boom B, ,which may be made solid in one piece or of two or more pieces, as may he. desired.
'lhe outer end of the boom B is supported by a rope or chain, C, one end of which is attached tothe boom B, or to a pulley-block attached to said boom.
lhe rope or cha-iu C passes around a pulley or pnlleys attached to the mast A, and its other end is connected with a windlass or other machinery for operating it.'
l) is the dipper-handle, the upper end of which is hinged/or jointed to the boom B, and to its lower end is rigidly and securely attached the dipper or scoop E.
The dipper E is provided with a bail, to which is attached a pulley-block.
l*1 is the rope or chain by which the dipper is operated.
rlhe end of the rope or chain l is attached to the bail of the dipper or to a pulley-block attached to said oail, passes around a pulley or pulleys attached to the boom B, and over a pulley attached to the mast A, and extends to the machinery by which the excavator is operated.
The excavator may be operated by a steam-engine placed upon the tbundation frame ot' the machine or in some other convenient position. u' l The length of the mast A, boom B, and dipperhandle D must depend upon the workto be done, and the length oi' either or all of them may he varied as required.
ln moving the material to along distance or-inl excavating in deep water, a long boom and a proportion ately long dipper-handleare required.
By this construct-ion ofthe excavator the work can e done ata greater distance from the body of the machine than with .other 'excavator-s, thus avoidingr the necessity of frequently moving the machine.
'lhcboom andalipper being both operated by ropes or chains, and entirely independent ot' each other, enable the machine to work to grade with greater certainty, and when a small quantityis to be excavated, by gradually lowering thc boom while the dipper is at work at grade,more material can be taken out without going below grade than is possible with other excavators.
iVith this construction, whenl the material is hard, the face of the dipper will be held firmly against it, enabling the machine to wo1'k'e`ectuall y in soil so hard that other excavators will not act upon it.
Having thus described our invention,
W'e claim as new and desire to secure by Lettersl Patentln an excavatiiig-machine having a boom arranged to swing vertically and horizontally, as described, ay
dipper, the arm of which is pivoted to the boom, and. operated by arope or vchainwhich passes over the outer end ot' the boom and the post, the said dipper being pivoted ata point intermediate between the ends of boom, the whole constructed and operating as set forth.
