CHARLES H. HASKER, OF PORTSMOUTH, VIRGINIA.

SUSPENDING BOATS.

Specicaton of Letters Patent No. 28,478, dated May 29, 1860.

To aZZ whom it may concern.'

Be it known that I, CHARLES H. HASKER, of Portsmouth, in the State of Virginia, have invented certain new and useful Improvenients for Suspending, Lowering, and Liberating Ships Boats; and I do hereby declare that the following is a full, clear, and exact description thereof, refe-rence being had to the accompanying drawings and to the marks and le-tters thereon.

Figure l of the drawings is a top view of a boat suspended on the davits and secured with the gripes around her; Fig. 2, a vertical section of the same; Fig. 3, a view of the means used for detaching the fallblocks from the hooks; and Figs. 4 and 5 views of the hook used for attaching the bow and stern of the boat to the fall-blocks.

In each of these figures like marks and letters are used to indicate like parts.

When the boat is suspended and properly secured, as shown by Fig. l, the gripes (a) are at each end (ZJ) attached to the bulwarks (w) by thimbles (c) and eye-bolts (cZ), the lashings (e) being roved through the eyebolts and thimbles; and the two ends (f) of the gripes being affixed to one thimble (g), constituting the bite. This bite-thimble (g) has attached to it a ring (ZL) through which passes a bolt (i) also passing through eyes (j) of bolts fixed in the bulwarks. The bolt (Z) has connected to one end of it a lever (7c), having a fulcrum, by which it can be moved in or out and thus hold or liberate this end of the gripe. From the fall-blocks (Z) the falls (m) pass over pulleys (a) in the davits (o) to belaying pins (p) in the bulwarks.

Secured to the fall-blocks (Z) are the lowering and stopping falls (g), which reeve through pulleys (7') on the davits and thence over pulleys in blocks (s), the end of one fall being spliced into the bite (t) of the other fall and that fall passing through or over a pulley (u) in the bulwarks to the belaying pin (o).

The stem post (w) and the stern post (y) have attached to them a hook (a), which is fully represented by Figs. 4 and 5. By Fig. 2 this hook (a) is shown passed through the eye (a) of the block (Z). The base of the hook (a) is connected to the projections of the plate (c) by a pin (cZ) upon which the hook turns. One plate (c) is secured to the stern post and another to the stem post, the holes (e) of the plates being for the attaching bolts. A clamp (f), working upon a pin which connects it to the plate, holds the hook (a) in the eye of the full-block. A plate or flat spring (g) underneath the hook serves both to mouse the hook, or prevent the eye of the block from being displaced, and to tilt the beak of the hook when the clamp is released. Attached to the outer end of this clamp is the end of a check or clamping cord (L) pass= ing from bow and from stern to a lever (2) secured to the side of the boat near the middle. Fig. 3 shows this lever and its attaching bar (j) with the ends of the check lines or cords afHXed thereto, and also another bar (70), in which are holes for a pin (Z), that secures the outer end (m) of the lever. In order to lower and liberate the boat from the suspended and secured position shown by Fig. l, a description of the means for doing which has here been given, a few hands and few motions only are necessary. One hand seizes the cord (a) which is attached to the lever (7c) and by an easy pull readily withdraws the bolt from the eyes and ring (Z1.) and thus liberates the gripes (a) other hands loosen the falls (m) from the belaying pins (p), which leaves the boat held up only by lowering and stopping falls (g). The loosening of the fall (g) from the belaying pin (o), and the lowering of the boat by this fal is then quickly and safely accomplished either in rough or easy sea. Upon the boats striking the water the in (Z) is withdrawn from the bar (c), which lets play the check lines (L) and the clamp (f), when the motion or weight of the boat frees the boat from the falls, the hook (a) playing up and the eye of the block (Z) moving oft' from it.

It will be perceived that through the means and the arrangement thereof herein set forth a ships boat can be safely and securely suspended on the davits and at a nioments notice, under any and all circumstances, be lowered and liberated and served with perfect safety and success.

Vhat I claim as my invention and desire to secure by Letters Patent is- 1. The bolt (z') eyes (j, j), ring (72,), as connected and arranged with the thimble (g) and the gripes (a, a,) operated as and for the purpose set forth.

2. The roving of the one lowering and stoppin fall (g) into the bite (t) of the other fa l, whereby the lowering of the boat is done by one fall as describe 3. The hook (z) clamp (f) cheek-lines 5 (L), lever (71') with its bars and pin as arranged for holdin block as set forth.

g and liberating the falls This specioation signed this 3 day of May 1860.
