Application fil d March 27. 1905. Serial No. 252.287.
To all whom it may concern.-
Be it known that I, ERNEST H. FREY, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, State of Ohio, have invented certain new and useful Improvements in Sectional Covers for Hatchways, of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.
The objects of the invention are to provide means for facilitating the handling of hatchcovers for the hatch-openings of freight or other vessels, whereby this work can be done quickly and in a simple and efficient manner.
Since vessels are now being built of increasingly large dimensions and with many hatch-openings, the removal and replacing of the covers in the shortest possible time with the least amount of handling has become a matter of vital necessity. The increasing size of hatch-openings in modern vessels also makes a divisional cover a matter of necessity. I accomplish these results by means of a sectional cover, the separate divisions being flexibly secured together to permit of folding the sections together, and in the various devices for lifting and drawing together the sections on edge in a compact folded form, as hereinafter described, shown in the accompanying drawings, and specifically pointed out in the claims.
In the accompanying drawings, Figure 1 shows a plan view of the device. Fig. 2 is a transverse section of deck and hatch-covering, showing the sections extended to cover the hatch-openings and the device for gathering together and folding the sections arranged above the cover. Fig. 3 is a similar view showing the sections folded together. Fig. 4 is a similar view showing the device for gathering the sections together and folding themarranged underneath the cover. Fig. 5 shows a modification of the operating device shown in Figs. 1 and 2. Fig. 6 shows the bottom of one of the sections. Fig. 7 is an end view of the cover. Figs. 8 and 9 are sectional views showing the hinges. Fig. 10 is an enlarged portion of Fig. 3. Fig. 11 is an enlarged section showing rollers under the cover, and Fig.12 is an end view of one of the sections shown in Fig. 4.
In these'views, 1 is the deck of the vessel 2, the coaming which encloses the open hatchway 3. The cover for the hatch-opening is shown to comprise sections 4, flexibly united ends 7 are turned over the flange of the 00am-- ing to shed water readily. (See Fig. 7.) On every alternate oint of the sections there are mounted in suitable beamings the rollers 8 in pairs, between each pair of which passes a line 9, which may be a chain or wire rope. This line also passes over a pulley 10 upon a post 11 at each end of the hatch-opening, and thence the line passes under pulleys 12 at the foot of each post, and from thence the line runs to any convenient source of power, such as a drum or windlass upon the deck.
The pulleys upon the posts give an elevation to the line which acts when hauled from either end to give an initial rise to the first joint between the sections, to which the double rollers are attached. This act raises and folds the first two sections together, and as soon as the line tightens it raises and folds in turn the next two sections, and so on until all the sections are folded together at one end of the hatchopening. The line can be hauled from either end andthe sections folded together at either end of the hatch-opening desired, which is a very desirable quality of the device, permitting the unloading of cargo from either side of the vessel without obstruction from the folded covers.
The hatch-covers should be made of as light material as possible compatible with stiffness and are shown of sheet metal, and they are stiffened by means of angle-bars 13, riveted on the under side near their meeting edges. The ends of these bars also serve as guides, and they are made a little shorter than the sections, so that their endsiengage (See Figs. 8 and 9.)
A flat metal strip is riveted to the anglebar and extends somewhat beyond it, thus clamping down the packing-strip. This packing-strip is formed of rubber or other elastic packing. It extends beyond the edge of the section to which it is attached and abuts against the angle-bar on the adjacent section, thus making a tight joint when the hatches are closed.
Lateral strips of packing 16, Fig. 6, rest upon the sides of the coaming and insure tight joints when the usual clamps are put on. A tarpaulin may be thrown over all, if desired, since the construction does not prevent its use.
When the hatches are to be opened, it is of course necessary that the outer edge of the cover should iind an abutment to strike against to prevent it from slipping over the edge of the coaming. To accomplish this and to also form a hinge upon which the outer section can turn, hooks 16 are secured to the edge of the coaming, which enter openings 17 in the edges of the outer sections as soon as they begin to rise, and thus hold them firmly in place. Upon each end section are placed keepers 18, to one of which the line is secured when that section becomes the outer section for closing or opening.
The posts at the end of the hatchway can be placed in sockets for removal or can be hinged so that they can be folded out of the way when. not in use, or they can be pivoted upon the end covers, as shown in Fig. 5. In. this view the p osts 1 9 are provided with bracebars 20 abutting against a shoulder 21 on the section, and they fold back with the section and rest on the deck at the lower end. The brace-bars then serve to prevent the folded sections from falling over upon the deck, as shown in dotted lines.
In Fig. 4 the line is seen placed under the cover. Here the end. posts are dispensed with and struts 22 are employed to give the joints the initiatory lift, so that the pull upon the line will erect the sections in turn. and fold them to "ether while drawing them to the end oi the hatch-opening, and openings at 0 can be made in the coaming to let the line through.
The liftingstruts are U shaped bars hinged to the under sides of the sections, and a sleeve 8 connects them. The sleeve serves the purpose of an antifriction-roller. (See Fig. 1.2.) Two small chains 0 are shown holding the struts rigidly in place; but they fold up within the sections when they are folded together.
Many additional parts can be employed or modifications made without departing from the spirit of the invention. For instance, ledge-bars 30-can be added to the inner sides of the coaming, upon which rollers 31 upon the under sides of the sections can travel. These rollers have adj us'table spring-bearings 32 of sufficient strength to support the sections out of contact with the coaming, and thus prevent friction upon and wear of the packing-strips, and yet not too rigid to prevent clamping the covers tightly upon the coaming. (See Fig. 11.) Latch-bars 33 are also shown. pivoted upon the posts for the purpose of securing the folded sections in their vertical position. These latch-bars are shown to be provided with inclined outer ends 34, so that the sections will lift up the latches of their own accord. as they are The engaging hauled. underneath them. edge of each latch is also inclined, so that while holding the sections in their vertical position the force applied to draw out the sections will. lift the latches.
The device is operated as follows: Assuming the sections to be laid [lat over the hatch opening and the clamps removed, the line being made fast to one end section of the cover and hauled from the other end, suitable power is applied and the line becomes taut and the tendency to straighten lifts the joint between. the first two sections and the meeting edges of these sections a little and the force coming from the other end slides the other sections toward the lifting-sections, thus folding them together in the vertical position. The line then lower roller on the folded section and lifts the upper roller at the next joint, thus folding it up in the same way. his procedure continues until all the sections are brought together and. stood on edge. To close the hatch, the line is attached to the outer section and the power applied from the other side of the ship. This straightens out the folded sections and spreads them over the hatch-opening in a horizontal position.
The advantages of the device are obvious, since the sections are folded together at the edge of the coaming, thus avoiding the obstruction of a pile of covers laid upon the deck and the interference occasioned thereby to the free passage of the deck and alleys between the hatchways.
Further advantages are found in the economy in time and labor effected by means of this appliance, and since vessels are now built with a large number of hatchways a large number of men would be required to remove and pile the covers on the deck or replace them in position.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is
