APPARATUS FOR LOADING BARRELS.

Application filed October 30, 1919.

To all whom it may concern:

Be it known that I, VILLIAM E. JOEIN- soN, a citizen of the United States, residing at Halifax, in the county of Halifax and Province of Nova Scotia, Canada, have invented certain new and useful Improvements in Apparatus for Loading Barrels;

and I do hereby declare the vfollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which Vform a part of this specification.v

This invention relates to new and useful improvements in apparatus for loading barrel packages from piers to ships holds and affords simple and eflicient apparatus for preventing the crushing of bilges and forcing heads out which often occur when barrels slip out of sling in mechanism as commonly employed.

The invention consists further in the pro- 'vision of an apparatus of this nature whereby barrel cargo may be loaded without the necessity of opening' up all the hatches as it will be necessary only to open one of suiiicient size through which a conveyer may be passed, and which is considered an important factor in loading material, particularly perishable cargo during the winter season.

My invention is illustrated in the accompanying drawing in which: .Y

Figure 1 is a vertical sectional view through a pier and a ship with my approved loading apparatus applied thereto.`

Fig. 2 is a top plan view of the movable platform.

Fig. 3 is a longitudinal view through the platform.

Fig. 4 is the side elevationof part of the conveyer apparatus and shock absorber.

Fig. 5 is a view in elevation of the parts shown in Fig. 4 taken on a plane at right angles thereto.

Fig. 6 is a detailed view showing the connections to the platform for moving the same in opposite directions.

Reference now being had to the 'details of the drawings bynumerals, l K

1 designates'a pier or dock and 2 a ship positioned adjacent thereto'in readiness to be loaded. 8 designates a movable platform or sled mounted on runners 4 and having on its upper surface longitudinally extending Specification of Letters Patent.

upward projecting side flanges, or curbings, to prevent sidewise displacement of the barrels placed upon said sled, and a rear end flange, or curbing, the other end of said sled being open and unobstructed. 5 is a bail shaped member pivotally connected with the opposite sides of the platform and having an eye 6 to which a hook 7, fastened to a cable 8 is adapted to be connected. Said cable passes over a pulley 9 fastened to a standard 10 rising from the deck of the ship and then winds about 4a drum 11 and thence over a pulley 13 secured to the standard 10 at a location above the point of attachment of the pulley 9 and thence extends to and is connected through the medium of a hook 15 with aneye 14 fastened to one end of the platform.v Said platform has near one end an upright member 16 to prevent barrels or other packages from rolling ofi when the platform is tilted.

A gang plank 18 bridges the space intermediate the 'pier and the side of the ship, and is disposed at an upward inclination and up which gang plank the platform with `its load is adapted to'be hauled by the cable.

A downward inclined platform 19 leads from theside of the` ship at the end of the gang .plankf to the upper end of the hatchway 20 in whichthe conveyer is positioned. In operation, as the sled is drawn upward upon the gang plank 18, onto the downward inclined platform\ 19, it tilts downward, thus automatically dumping the barrels on the sled, the barrels rolling off the open end of said sled. Said conveyer is made up preferably of hollow skeleton sections 21 preferably of metal and connected together in any suitable manner, any number of these sections being employed to reach different depths in the hold of the ship. Shock ab'- sorbers designated by numeral 21 and consisting of curved resilient bars are preferably positioned within the bottom section of the conveyer and their lower ends are upwardly and inwardly curved as shown in the drawing. Screws 22 passing through the sides of this conveyersection and bearing against the upwardly curved portions of the shock absorbers are provided for the purpose of regulating the tension of the latter. Vithin the remaining section of the conveyer is preferably disposed a slightly modilied form of shock absorber, comprising curved resilient bars 21, a pair thereof being disposed at each side ofeach of said conveyor' sections, one bar ot said pair being disposed in a downwardly curved direction, and the other in an upwardly curved direction, said bars being secured at one thereof to the conveyor section, and the rree end of one oi" said bars being disposed in proximity to the other bar at a point substantially midway of the length thereof, so that when one bar is iieed by cont-act therewith of a barrel passing` through the con-- Voyer section, it will conact with the other bar, andthe two bars will then be simultaneously flexed. Fastened to the lower portions or the conveyor are additional. shock absorbers 23 iorined ot resilient bars of metal which are disposed downward inclinations, and against which the barrels or other packages are adapted to contact to break gradually the tall thereof and down which inclined portions barrels are adapted to roll into the hold. llhen the druin is rotated in one direction the platform loaded with barrels, may be hauled up the inclined gang planlr and down the inclined track 19, the be els being prevented trom rolling oliA the rearend oi the platform by the standards thereon., and when the platform tir'V s down upon the inclined track Vi9 upon the deck of the boat, barrels will roll oi'f the forward end or the platform without *en ference frein the bail shaped nieinber which will be raised out of the pathl ot the barrels. As the barrels leave the platform they will roll into the upper end of the conveyer and fall down therein, their progress being rested by their coming in Contact with iu arious shock absorbers against which they contact as they pass down into the hold.
