Description
'ttitrd Stabat THOMAS SAULPAUGH, OFl ROCK ISLAND, ILLINOIS.
` Leners Patent No. 101,630, and 'Sapman 2o, i870. I f
" 'IMPRovEMENT IN DnRRIc'K-BQATS.
To all whom it may concern Be it known that I, TnoMAs SAULPAUGH, ofRock Island, in the county of .Rock Island and State of Illinois, have invented certain Improvements in Der,- rick-Boats, of which the following is a speeication, reference being had to the accompanying drawing.
My invention relatesto oating .derricks, used in building wharves, piers, &c.; andA It consists in mounting upon a suitable Iboat a derrick and an engine or horse-power for operating the same, vand in so bracing the derrick to the boat as to a'void theuse lof guys or ropes from the derrick to the shore, or to cribs in the Water, as required in the present boats. l i
. The drawing represents my 'improved (lerrick-boat in perspective.
In ioating derricks, as heretofore constructed, the boat served merely-as a transport for the derrick,and a foundation for the derrick-post, when in-use, the latter being supported by guys stretched from it to shore, or to .cribs builtin the water for that express purpose.
rEhe plauis open to serious objections, as the cribs are expensive to build, the guys oftentimes a hinder-V ance to navigation, and in need of constant adjustment, as the boat is moved. l The object of my invention is to `produce a boat having the derrlck so mounted thereon as to avoid the necessity of any other' braces than' those connecting between the'derrick. and' the boat, -so that the boat can be moved from place to place without stopping to build cribs or adjust guys. In constructing my derrick-boat, I provide a boat,
A, of proper size, and of any suitable style or form,
and strengthen it bymeans of longitudinal bulkhead@ n, and transverse tie-rods, o, as shown. i' y Across the middle of the boat I erect a strong npright frame, D, consisting of thetop and bottom timbers, t and l, and the uprights, g and h, framed strongly together and secured rigidly to the boat.
The Schedule referred to in these Letters Patent and making part 0f the same Near one end of the boat Imount a derrick-post,
a, about one-third higher Vthan the frame D, and support its upper end by two braces, j, which latter are secured, at one end, to the upper corner of frame D,
.and connected together'at theirY opposite ends, 'as
shown.
The derrickpostI provide with a hinged boom, b, and tackle, c d, and upon the opposite end of the boat, at the point B, I place an engine or horse-power, with one 4or more drums, and connect the derrick-ropes therewith.
The enginev or other motor serves also as ballast, tokeep the boat in an upright position, and prevent its being overturned when Weight is brought upon the derrick. When, however, unusually heavy work is to be doneLadditoual ballast may be placed-in the boat.
When the del-rick is thus mounted and arranged, a strong, stiff, and convenient oating derrick is produced, which can be readily transported Afrom place to place without delay or hindrance to navigation, andl immediately set to work, without building cribs, or running out and securing guy-ropes or stays to hold it in position, v v
Having thus described my invention.
,A floating dex-rick, consistingr of the boat A,v having the rotating post a, hinged brace b, withthe tackle c andtl mounted thereon, in such a manner as to dispense with any other guys or braces than those which connect the post a to the boat, substantially as dcscribed.
THOMAS SAULPAUGH.
