IMPROVED BOAT-DETAGHING TACKLE.
"ein Stimuli nient in in ilgtse tctttrs gnant mit mating part ht tige stmt.
TO ALL WI-IOM IT MAY CONCERN:
Beit known that I, T. C. HARGRAYE, of Boston, in the county of SniTolk, and State ofA Massachusetts, have invented an Improved Boat-Detaching Apparatus; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my in-veution sutlcient to enable those skilled in the art to practise it.
In ships at sen, during heavy or rough weather great diiliculty is often experienced in so lowering the boats that they strike so squarely upon the water as not to upset or swamp, and various means have of late been contrived to insure the safety of a boat in getting it fairly launched. Most of these devices, however, are wanting either in simplicity, cheapness, or effectiveness, or cannot be so disposed in boats as to warrant their use; and my invention has been made with a view of obtaining a beatdetaching mechanismA which should combine thc minimum of simplicity and eectiveness with low cost and convenient and unobjeetionable location within the boat. To accomplish this, I hang at each end of the boat, in a stationary block, a swing-tumbler, having in its lower end a semicircular notch or slot, into which the tackle-hook orring enters, and I lock these tumblers in vertical position (to suspend and secure the boat to its tackle) by sliding-rods or bolts, connected at the centre of the boat with a lever, and at opposite sides of the fulcrum thereof, each of these bolts having projections between which thelower end of each tumbler fits, so that when the lever is brought into line with the slide-rods these projections hold the tumblers securely in place, with no possibility of detachment of the tackle-rings from the boat, while, by turning up the lever, the drawing iu of the sliding-links swings each tumbler on its pivot, bringing it into such inclined position that the weight of the boat swings them upward simultaneously, releasing the rings therefrom and allowing the boat to drop. Itis in this specific construction and arrangement that my invention consists.
The drawing represents at A a boat having my detachingapparatus, the side opposite to which the mechanism is applied being broken away to clearly show the same. B and C are details, B showing the tackle-ring as locked to the boat; C showing the locking-tumbler as partly withdrawn from its block. a denotes the boat, bb stationary blocks or bearings fixed in the stem and stern thereof, each of these blocks-having a swingingtumbler, c, hung in the top ot` the block on a'pin, d. The inner side of each block below the bearing is recessed, as seen at e, and the lower end of each tumbler has a notch, f, for receiving the tackle-ring or hook g, which swings into the recess e in the block. When it is also within the tumblernotch, and when the tumbler, with the ring, has been-thus swung into the block, as seen at A. and B, the tumbler is in vertical position, and the stress of the weight of the boat comes directly upon the pins d, and has ne direct tendency to swing the tumblers out of position. To lock them in position, however, and to operate them to detach the boat, I employ two slidinglinks or rods i, the outer end of each of which enters the slot in the adjacent block b, and has projections lc, between which the lower end of thc tumbler lits, as seen in the drawings. The sliding-rods are connected by a lever, l, swinging on a fulerum, m., the rods ybeing `jointed to the lever on opposite sides of this fulcrnm, so that by turning the lever down into line with them, as shown at A, the reds are forced outwardly, and the joints, fulcrnm, and rods being brought into the same general line, the rodsare locked in this position, as will be readily understood, while by turning up the lever the rods are drawn inwards.
To attach the boat to the tackle-rings, the rods are slid inwardly, bringing each tumbler into the position shown at C. Both rings are then slipped into their respective tumbler-notcl1es,`as seen at C, and the tumblers are pressed into their blocks, carrying with them the rings and the rods, u'ntil by pressing down the lever Z the tumblers are brought into vertical position, in which position they are locked by the rod-projections 7c and the lever Z, as seen 1t A and B. When the boat has been lowered and is to be detached, the lever Z is thrown up, drawing inthe rods i, and bringing the tumblers into the position shown at C, when the weight of the boat acting upon the tumblers swings them up, releasing the rings from their notches, and both ends of the boat are thereby simultaneously detached and fall squarely upon the water.
I claim, in combination with the sliding-rods k and lever Z, the stationary blocks having swing-tumblers, in notches of which the tackle-rings are held, these tumblers being locked in position v and Operated to detach the boat, substantially as set forth.
T. C. HARGRAVE.
