ing the said hatch cover in a convenient and sim lc manner, to avoid leakage.

The invention is clearly illustrated in the accompanying drawing which forms a part of this specification, and in which-- Figure 1. is a perspective view of a hatchway with the cover partly broken away, and showin the a iplieation. of my .faetcncrs in the re ierred orm. Fig, 2d1selose's one of the asteners in side eleir'ation in connection with and in position on the several. different parts comprising a hatchi vay. Fig. 3 is an.-

other view of the same construction. Fig. 4 is a sectional View of the same construction as showing the adaptation of the several different parts.

Like figures refer to like parts in all of the figures in the drawing,

Each of my fasteners, in. the preferred form, consist in practicall "the same eomhi nation of parts as disclose in ,a former application for a similar dev cogfilcd May the exception that the membei 10 is 001111308? bracket, '9 the dog," as a movable member between said set-screw andmcmber 10, which, m p gm i fu crumogi thereto at 12 arulh'eld'inplace by a cap-acrow 1 1cm discloses length: i

The method of ap ilication and tho operation thereof is as follows: All parts being in position as shown, the sctmcrcw H is drawn up and exerts pressure upon the strip 5,

edge of the canvas cover as shown; this action has advanced the member 11) toward the coaming 2 and by reason of thcroverscly inclined ways as at 18 and 19, the result is that limited distance, which will he Rnihciont in most instances to also confine tho batten bars on the top of said canvas cover; it", however, the said bars are not ouilioiently confined thereby, it is only necessary to operate the "cap-screw l4, and thgreby adjusting an one of the fasteners, to or nponsate for an ifi'er ences that'rnay occur in actual, practical use.

Having thus shown and. described my in Vfilltlflfl so that, to those who are skilled in this art, it will appear obvious, what I claim as new and wish to protect by Letterc'Pateat is:

'In a mechanism of the character described, the combination of a coaming of a hatch wjay, brackets attached thereto, a coverjfor said hatch way together with a canvas over cover therefor and a plurality ofbatten bars engagingeach other and a plurality of parts do pendant u on said brackets andpwh comprisinga-member ,10 in connection with a member 11 and a ca yscrew'l t all eo'operat ing to exert pressure on said batten bats downwardly to'causc the said hatch cover to become firmly closed, as described.
