HATCH-COVER.

Specification of Letters Patent.

Patented J une 8, 1920.

Application filed November 10,1919. Serial No. 336,812.

To all whom it may concern:

Be it known that I, JOSEPH S. 001), a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Hatch-Covers, of which the following is a specification.

This invention relates to hatch covers and particularly to means for supporting the stack of sections of a sectional cover when removed to one end of the hatch.

Sectional hatch covers have been supported in various ways by bars attached to the hatch or deck but in all instances these devices were placed by hand. The present inventon therefore relates to supporting devices moved into supporting position by the cover itself in its removal.

Further features of invention will more fully and at large appear from the following description, drawings and claims.

Figure l is a longitudinal vertical sectional view of a hatch and cover provided with my invention; Fig. 2 is a horizontal section below the cover; Fig. 3 is a view similar to Fig. 1 with the cover removed; Fig. 4 is a sectional detail on the line 4.4:, Fig. 3; Fig. 5 is a sectional detail on line 5-5, Fig. 3; Fig. 6 is a sectional detail on line 6-6, Fig. 8; Fig. 7 is an end view of the cover section; Fig. 8 is a view similar to Fig. 1, showing a modified form of bar supporting device; and Fig. 9 is a sectional view upon the line 9-9, Fig. 3.

In the arrangement shown in the drawings, 1 represents the deck which is provided with the usual hatch (roaming 2 surrounding the hatch opening. This coaming is provided with an angle iron band 3 near its top for deflecting the sea as it washes over the deck. This is located near the iippeneclge of the hatch coaming but low enough so as not to interfere with the depending flanges of the cover as will appear.

The cover comprises a plurality of similar sections 4 each having a cleat 5 along the upper edge and a depending flange 6 adapted to extend down into the hatch and with another cleat 7 on the underside at the opposite side for engagement of the cleat 5 of the next section. Each of these sections is provided with an outside flange 6 bent down to overhang the coaming. The several sections are made of varying widths so that they will nest one above the other as shown in Figs. 3, 5 and 6. The flanges 6 are beveled at their ends as shown in Fig. 7, so that they will clear bolts and other obstructions on the inner faces of the coanling. These flanges 6 also serve as stops so that when the covers are withdrawn, as shown in Fig. 3, they will abut one against the other. In addition to sections 4 the cover comprises an end section 8 similar to the other sections except that it is provided with a depending flange 9 for engaging the end of the coaming when the cover is closed, as shown in Fig. 1. This section is likewise provided with side flanges 6 which preferably form a part of the flange 9.

So far the description has been confined to a construction which is old and well known in the art and the detail description of the new device will now be given. The end member of the hatch coamingQ is cut away in both of its upper corners as shown at 10, and inside of the coaming, and just below the bottom of each of these openings, is a roller 11 mounted upon a pin 12 supported in the side of the coaming and in a supporting block 13 secured to the end coaming. The periphery of this roller is arranged in alinement with the bottom of the opening 10, as shown in Fig. 5 and for a purpose to be described. Secured to the inside wall of the sides of the coaming are guides 14 of substantially the form shown and adapted to support one end of a roller pin 15, the other end of which is-monnted in the side coaming. The pin 15 is near the top of the guide and is provided with an enlarged inner portion 16 forming a bearing for a roller 17. The guides are so formed that they provide a rectangular shaped opening for the reception of a cover supporting bar 18 which is provided with an opening 19 adapted to receive a pin 20 supported in a block 21 secured to the underside of the cover section 8 near the flange 9, as shown. This block fills the opening 10. The opening 19 is larger than the pin 20 to provide lost motion at this point and to prevent any uneven movement of the cover section 8 resulting from an uneven pull on the bar 18. The bar 18 has an offset portion 22 which connects the portion 18 with a tail portion 23. This portion extends through the guide, as shown, and below the roller 17 The bar preferably has its end beveled at 24 so that it will sheer through coal or grain which might extend up within the hatch coaming. The uppermost cover section is rovided with rings 25 or other cable attac ing devices for manipulating the cover. The rear end of the cover supporting bars may be arranged in housings 26 as shown, which protect the mechanism, or these housings may be omitted as desired.

In operation the deck hands apply a cable to the rings 25 and the upper cover section is moved along the adjacent lower section until their flanges 6 abut when the next lower section will be moved and finally the bottom section 8 will be slid off of the end of the hatch. WVhen this occurs, however, the supporting bars are withdrawn from the coaming along the rollers 11 and 17 until the entire cover, in nested arrangement, is moved off of the end of the hatch and supported by the bars. The cover remains in this position until it is returned to closed position by the closing operation. The supporting bars preferably move out on a slightly upward incline so that the cover sections when being closed will move at the proper angle to insure the engagement of the cleats 5 and 7.

In a modification shown in Fig. 8, the portions 18 of the bars are provided with rack teeth 27 adapted to engage pinions 28 keyed upon a transverse shaft 29 mounted in the end of the coaming, whereby when the stack of cover sections, is withdrawn both sides of the stack will be moved at the same speed and to the same extent, doing away with a kinking or torsional movement of the stack upon the coaming.

Having described my invention, I claim:

1. In a hatch coaming and cover structure, a coaming, a sectional cover, means for supporting the removed stack of cover sections, and operative connections between said means and said cover whereby the former moves with the latter.

secured to the cover and movable therewith for supporting the stack of cover sections when removed to a position beyond one end of the coaming and comprising bars secured to the cover and movable back and forth therewith, and rollers arranged above and below the bars for guiding and supporting the same.

4. In a combined hatch coaming and cover structure, a coaming, supporting bar rollers rotatably mounted near the end of the coaming, guide rollers mounted upon the sides of the coaming and at a distance from the first mentioned rollers, and supporting bars secured to and movable with the lowermost cover member and extending above the rollers near the end of the coaming and below the rollers on the sides of the coaming and thereby forming a support for the stack of cover sections when removed to a point beyond the end of the coaming.

5. In a combined hatch coaming and cover structure, a coaming, gear rollers arranged at the end of the coaming and inside the same,driving connection between said gear rollers, guides arranged on the inner sides of the side walls of the coaming, rollers arranged in said guides, and supporting bars having teeth engaging upon the top of the gear rollers, said bars engaging below the rollers carried by the guide.

In testimony whereof I affix my signature.
