IMPROVEMENT IN MEANS OF' RAISING FLATINGT'IMBERAND LVOADING VESSELS THEREWITH.

Specification forming part of Letters Patent No. 143,873, dated October 21, 1873; application filed April 19, 1813.

To all whom it may concern:

Be it known that I, ADAM BULMAN, of Newburg, in the county of Orange and State of N ew York, have invented. a Floating Steam-Scow for Loading Timber in Vessels, of which the following is a specification: s

The present mode of loading timber in vessels is very tedious, and it requires many days of hard and disagreeable labor to fill a vessel.

' My present invention is intended to alleviate the labor and to accelerate the loading of a vessel with timber. For this purpose I build la scow, consisting of three parts, joined together lengthwise by door-beams at the bottom of the scow, and leaving between each two parts a hoistway for' a long platform or carriage, making the distance between the end of the carriage can Ybe hoisted upindependently, so that the back end can be elevatedmore than the font end, the sliding -of the log from the carriage into the vesselwill be done easily; besides, thev carriage-frame contains rollers, on which the log rests, by which means the log will roll down the inclined plane with very little help. The hoist ingand lowering of the carriage and the pulll ing in of the log into the vessel are done by i means of a steam-engine and drums, on which ropes are woimd, so that by this steam-scow a few men will do as n1ucl1 work in shorter time. than at present many men can accomplish. The scow itself is fastened, during the operation of loading the vessel, to the same by outriggers; two in the middle hold it to the stern, and one on each side to the side of the vessel. AThese outriggers 'are made in such a way that they allow the vessel to settle lower in the waterwthout interfering with the scow, and have only4 t-o be changed two or three times during the time of loading the vessel to her full capacity. lhe scow can also be fastened close to the vessel, or farther off, as the case may require.

Referring to the drawings, Figure 1,Plate l, represents a side view of the steam-scow when attached to a vessel. Fig. 2 on Plate 1 is a plan of the scow during operation. Fig. 3 on Plate 2 is an end view of the scow.

A is a vessel loading with timber. P1 P2 are the two ports to admit the same. G1 G2 are the fastenings to which the two outriggers F1F2 are attached. H H are the outriggers, which hold the center part of the scow to the stern of the boat. C102 C are the three parts of the scow; Yl Y2, the two hoistways. D1 D2 are the carriages, with rollers r r. E E are the guide-posts, between which the carriages move up and down. c e are main-braces; besides which knees at the bottom of the posts hold the same to the body of the scow. The bottom or floor timbers S S hold the three parts of the scow together, and,when the scow is in position, braces W can be put in to connect thel tops of the guide-posts E E. M1 representsa log in the hoistway Y1, elevated to' a position to pull it into the vessel. The vhooks N are attached, which, by means of a rope, are connected to a' drum, and, by means of the steam-engine B, the log M will be pulled into `the vessel, the rope running over a block fastened in the far-off end of the vessel. M2 is another log, in the second hoistway Y2, just ready Vto be hoisted up. The carriages D1 D2 have yokes T1 T2 attached, which straddle the logs, and to the yokes are fastened rollers R, so that the ropes from the drums Q, leading over the guide-rollers R R and held by the top beams Ul U2, will hoist the carriages. .As each rope has a separate drum, which can be moved 'or stopped independently, each end of each carriage can be hoisted or lowered separately, and each log can be pulled in independently of the other. Each carriage can be worked alone or together, as circumstances may. require. L represents the level of water, to

"which the scow can be sunk down by ballast,

or by letting water into the different apartments until the required depth of vwater in the hoistways is reached, if the scowshould not draw water enough to admit logs into the slips.
