BELEASING-HOOK FOR LIFE-BOATS.

Specification of Letters Patent.

Patented June 4, 1918.

Application filed July 13, 1917. Serial No. 180,316-

To all whom it may concern:

Be it known that I, EDWARD THOMAS KLIPPERT, a citizen ofthe United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful improvement in Releasing- Hooks for LifeBoats, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to releasing hooks for life-boats. With life-boats it is desirable to have at the end of the rope and tackle that lets the life-boat down at each end releasing hooks which can be simultaneously'released with certainty and expedition. To this end hooks have been devised for that purpose. However, many of the hooks of the prior art are open to various objections such as liability of the releasing means to become inoperative due to rust or ice, and various other objections.

It is to obviate these objections and make a simple and reliable device that this in vention is designed.

In the drawings:

Figure 1 shows the releasing hook in position on a boat in connection with the rope and tackle.

Fig. 2 is an elevation partly in section of a hook.

Fig. 3 is a perspective of the hook in locked position.

a designates the tackle block, b the tackle hook, c the ring on the forward or rear end of the life-boat connected with the releasing hook.

The releasing hook comprises simply an elbow d at one end provided with the hook recess 6 at the other end pivoting the jointed elbow f, whose bill r enters the hook recess 6. The shank of the elbow d is bored and counter-bored to guide the sliding bolt h and house its actuating spring 2' engaging between the collar j and the cap nut 70. This bolt has a nose which is ordinarily thrust into the recess m, in the bill of the jointed elbow.

The counter-bored portion of the shank of the elbow d or the spring chamber is packed with grease and this is forced up around the sliding bolt h by turning the cap nut 77. This insures the sliding bolt Note that the opposed upper and lower arms of the two elbows do not have their inner arcuate surfaces struck from centers in a vertical line when the device is in a vertical position but that the center of the upper one is advanced to the center of the lower one. The purpose of this is to hand the tackle hook in advance or to the right of the boat ring. Hence when the bolt h is released the weight of the boat is supported on the jointed elbow to the right of the point where it is supported on the rigid elbow. Consequently the load serves to pull out the jointed elbow when the boat is released and immediately release the boat.

The flexible cable cord n can connect the bottom of the sliding bolt with a convenient place for the operator of the boat to release the hooks or any common device for simultaneously pulling the two releases at the same time can be employed.

From the above description it is apparent that no projecting levers etc. are left in the way where the releasing hook is liable to be released at the improper time and cause a catastrophe.

What I claim is:

1. A releasing hook for life-boats, comprising a pair of elbows jointed together, one provided with a bill fitting into the recess of the other, said bill also provided with a bolt recess, the shank of the other elbow being bored for a guide and a spring housing, a sliding bolt, and a spring contained in the housing adapted to project the bolt into the bolt recess.

2. A releasing hook for life-boats, comprising a pair of elbows pivoted together, one provided with a hook recess and the other bill provided with a bolt recess, the shank of the first mentioned elbow being bored to form a guide and a spring housing, a bolt sliding in said guide, a spring contained in the housing for projecting the bolt into the bolt recess, and a screw cap for closing the spring chamber and acting as a forcible means of ejecting grease packed in the spring chamber along the bolt.

3. A releasing hook for life-boats, having in combination, an elbow provided at for normally keeping "the bolt projected,

member connected with th'ebolttand passing slidably through the cap nut, and a second elioo'i'u pivoted to the lower end "of the first elbow and having a billat its upper end adaptedto fit 'intothe said crossrecess and proVi'ded'tvith ab'olt recess 'for the saidnose of the bolt.

4. A rel-easing hook for life-'b'oats, 'c'omprisiiig a pair of elbows, one of which is przwiaed at its top With a cross recess and the otherii' ith abiu horizontally disposed in said cross recess when the hook is in service the said elbows having their 0pjfiosed upper and lower inner surfaces out an erasure centers of which are arranged so that "the upper center is in advance of the lower centerin the direction of separa tion of the parts, and me-ansffor rele'asabiy holding the saidbill in the said cross slot.

In'testiinofi'y whereof lsign this specifica- 1 tion.
