HATCH FOR BOATS.

gpecification of Letters Patent.

Patented May 16, 1922.

Application filed March 12, 1917. Serial No. 154,201.

To all whom it may concern:

Be it known that I, ALoANzo D. NnwcoMB, citizen of the United States, residing at Norfolk, in the county of Norfolk and State of Virginia have invented certain new and useful Improvements in Hatches for Boats, of which the following is a specification.

My invention relates to new and useful improvements in hatches for boats and more particularly for life boats.

The object of my invention is to provide a hatch of this character so mounted that it can be readily moved from above the hatch opening and readily closed and held in said closed position and tightly heldso as to form a water-tight joint with the upwardly extending flange surrounding the hatch and at the same time providing a hatch which can be easily opened from above or below, and locked from above or below the deck.

Another object of my invention is to provide a simple, cheap and effective hatch of this character having certain details of struc-' 'ture and combination of parts hereinafter more fully set forth In the accompanying drawings:

Figure 1 is a. top plan view of alife boat showing my improved hatch appliedthereto.

Figure 2 is a side elevation of'Figure 1 both hatches being closed.

Figure 3 is an enlarged perspective View of a portion of the hatch coaming showing "the means for looking it from below.

Figure 4 is an enlarged sectional view taken on the line lshowing the. hatch cover closed.

Figure 5 is a vertical sectional view taken on the line 5-5 of Figurel showing the hatch cover closed.

Figure 6 is a perspective view of the hatch locking means.

Referring now to the drawings, 1 repre sents a life boat of the character for which my improved hatch is more particularly designed. The deck 2-, as shown, is provided with a hatch at one end and one in the center, and it will be understood that there may also be a hatch at the opposite end of the boat. While showing this specific arrangement of hatches, it will be understood that they may be arranged at any point on the deck of a boat which may be found most convenient.

The deck 2 of the boat surrounding the hatch opening 8, is provided with a coaming having at its lower ends the lateral extension 5 through which passes bolts 6 for rigidly securing the sarne to the deck of the boat. The upper end of the coaming 4 is provided on its outer edge with a flange 7 and the upper fiat face has a raised central portion 8 as clearly shown in Figs. 4 and 5. The deck 2 of the boat surrounding the hatch opening is provided with a plate 8 arranged on edge and which "forms engaging means for the hatch locking means as will be hereinafter more fully described.

The hatch 9 as shown is of a circular form to correspond with the hatch openings and is provided at one edge with the outwardly extending ears 10 and 11 which straddle the vertically disposed cars 12 and 13 carried by the deck adjacent the hatch opening and passing through the ears 10, 11, 12 and 13 is a rod or pivot 14 whereby the hatch is free to swing from above the hatch opening as shown in Fig. 1 of the drawings. The ears 12 and 13 are of a length to allow the hatch to assume a perfectly horizontal position so that it will rest flat upon the coaming 4; to form a tight joint for closing the hatch opening.

The hatch 9 asheretofore stated is of a circular form and of a diameter equal to the diameter of the flange 7 carried by the upper end of the coaming 4 and has at its outer edge a downwardly extending flange 15 which is of a width greater than the thickness of the coaming 4:, the purpose of which will be hereinafter more fully described. The lower face of the flange 15 is covered with a rubber packing 16 which is held thereon by the two metal rings. 17 and 18 which are secured to the hatch by screws 19 which pass through the packing and are screwed into the hatch. The rings 17 and 18 are spaced apart a distance equal to the width of the raised portion 8 of the coaming a so that the raised portion engages the packing 16 and forms a tight joint, while the rings 17 and 18 rest in the recess portion 20 and 21 as shown in Figs. 4 and 5.

The ring 18 is provided'with a downwardly extending lug 22 to which is pivotally connected the bell crank lever 23 which extends downwardly through the hatch opening and is provided with a hooked end which engages the lower edge of the plate 8. The opposite nd of the bell crank lever 23 has pivotally connected at 24 the rod 25 which extends upwardly through an opening 25 in the hatch 9 and is provided with a ball or handle 26 above the hatch which tightly closes the opening 25 when the rod is in a downward position. Surrounding the rod is a coil spring 27 which has its upper end engaging the lower face of the hatch and its lower end engaging the outer end of the bell crank lever 28, whereby the same is normally held in the position shown in Fig. 5. By this construction it will be seen that the holding means is automatic in its locking operation and is released by raising the rod 25.

In order to provide means for locking the hatch tightly upon the coaming from within the boat, I provide the coaming lwith the plates 28 on its inner periphery which are arranged at proper intervals as shown in Fig. l and the hatch 9 is provided with downwardly extending lugs or rods 29 arranged opposite the same. Pivotally mounted upon the lower ends of the lugs or rods are levers 30 which have the cam faces 31 at their outer ends and which when oscillated extend under the plates 28 and draw the hatch firmly down upon the coaming as shown in Fig. ft of the drawings.

Having thus described my invention, what 1 claim and desire to secure by Letters Patent is:

l. The combination with a boat having a hatch opening, a pivoted hatch covering said opening, and a horizontally pivoted latch carried by the lower face of the hatch on the inside of the opening.

2. The combination with a boat having a hatch opening, a coaming surrounding the opening, the upper face of said coaming having a raised central portion, a hatch having a packing around its outer edge resting upon the raised portion of the coaming, and rings secured to the packing on the inside and outside of said raised portion and fastening the packing to the hatch.

3. The combination with a boat having a hatch opening, a coaming surrounding the opening, the upper face of said coaming having a raised central portion, a hatch having a packing around its lower face resting upon the raised portion of the coaming and extending on each side thereof, a ring on each side of the raised portion, screws passing through the rings, packing and entering the hatch and means for locking the hatch on the coaming.

l. The combination with a boat having a hatch opening, a coaming surrounding the opening and having a lateral securing flange resting upon the deck, means passing through the flange for securing the coaming to the deck, a hatch pivoted to the deck and resting upon the coaming, a bell crank lever pivoted to the hatch and having a hooked lower end engaging the boat for holding the hatch closed, a rod connected to the upper end of the lever and extending out through an opening in the hatch, a spring surrounding the rod between the lever and hatch, and means carried by the upper end of the rod for operating the bell crank lever.

5. The combination with a boat, having a hatch opening, a coaming surrounding the opening and having a lateral securing flange resting upon the deck, means passing through the flange for securing the coaming to the deck, a hatch pivoted to the deck and resting upon the coaming, a bell crank lever pivoted to the hatch and having a hooked lower end engaging the boat for holding the hatch closed, a rod connected to the upper end of the lever and extending out through an opening in the hatch, a spring surrounding the rod between the lever and hatch, and a ball carried by the upper end of the rod for operating the bell crank lever and normally closing the opening in the hatch.

6. The combination with a boat having a hatch opening, a coaming surrounding the opening and having a lateral securing flange resting upon the deck, means passing through the flange for securing the coaming to the deck, a hatch pivoted to the deck and resting upon the coaming, a bell crank lever pivoted to the hatch and having a hooked lower end engaging the boat for holding the hatch closed, a rod connected to the upper end of the lever and extending out through an opening in the hatch, a spring surrounding the rod between the lever and hatch, means carried by the upper end of the rod for operating the bell crank lever, inwardly extending plates carried by the inner face of the coaming, downwardly extending members carried by the lower face-of the hatch,and cam members pivoted to said rods and adapted to engage the plates for look ing the hatch down on the coaming.

7. The combination with a boat having a. hatch opening, a coaming surrounding the opening, a pivoted hatch resting upon the coaming, a horizontally pivoted hatchcai ried by the lower face of the hatch within the coaming and operated from above the hatch, and means carried by the hatch for locking the hatch closed and operated from within the boat.

In testimony whereof I affix my signature in the presence of two witnesses.
