UNITED STATES PATENT OFFICE.

CHARLES F. HU'ZDGINS, OF NORFOLK, VIRGINIA.

DETACHING DEVICE.

Application filed May 23,

, of which the following is a specification.

My invention relates to detaching devices to be used for facilitating the preparation for launching life boats from vessels and for disengaging and removing the covers and retaining means ordinarily employed for protecting and securing the boats to the decks of vessels.

My invention is an improvement upon a Letters Patent issued to me on September 6, 1909, and numbered 969,628 for fastening for life boat covers.

My present invention provides forthe use of a spring and adapts the device for any purpose where a holding means is desired which may be quickly detached when required.

Further objects and advantages will be more fully described herein and specifically pointed out in the claims hereunto annexed recourse being had to the accompanying drawing forming a part of this specification in which:

Figure 1 is a side view of my improved detaching apparatus in a locked or holding position.

Figure 2 is a plan of the same.

Figure 3 is a bottom plan showing the spring in place on the plate port-ion.

Figure 1 is an end View.

Figures 5 and 6 are side views of a modified form of shackle.

Figure 7 is a plan of the plate or flat spring.

In the drawing like reference numerals indicate similar parts in all the several views.

1 is the plate or body portion having a flat form in cross section and is provided with a reduced portion or neck 2 upon the extremity of which an enlongated ringor eye 3 is formed for passing a rope or lashing therethrough.

4: is a hole near the opposite end of the plate 1 for hingedly positioning the latch iod 5 which is normally horizontal, as shown, and is provided with a bent or offset end at right angles to the shank of the rod and is bent into an eye 6 through the end of the plate so that the rod 5 may be swungin a 1923. Serial No. 640,958.

semi-circle after being released by the shackle 7, as indicated. in Figure 1.

The loop or bow of the shackle 7 is indicated by the numeral 7, and its free ends, by the numeral 8, the latter being square at the bottom surfaces upon which the spring 11 presses.

9 is a pin for movably fitting the shackle upon the sides of the plate 1.

10 is a hole in the upper portion of the shackle bow 7 for a lanyard for pulling the same to the left and releasing the latch rod 5.

11 is the leaf or plate spring fastened by the screws 12 passing through the orifices 11, (Figure 7), to the bottom of the plate 1. The spring is put in tension when the shackle portions 8 are moved and locks the shackle in a vertical position or nearly horizontal, as indicated by the dotted lines below v the numeral 17 in Figure 1.

In Figures 5 and. 6 I show a modified form of shackle in which there are angularly disposed flatsurfaceslS and 1 1 for engagement with the spring 11 for two positions of the shackle, as shown.

.16 is a suitable rope or lashing secured to the eye 3 and 15 is a similar rope attached to the object to be released when the shackle is pulled to the left by the lanyard 17 which allows the rod 5 to fall and effect a release.

My invention is cheap to manufacture, is effective in operation and may be used upon shipboard or elsewhere for quickly detaching an object from its fastenings.

I claim:

1. In a detaching device, a flat perforated plate member, a hinged latch rod thereon, shackle holding and releasingnieans therefor bent through the perforation and around one end of the plate, and spring means adapted to press upon two flat surfaces of the shackle forlocking the same in a holding and releasing position.

2. In a detaching device, a perforated plate member having a hinged locking rod at one end thereof bent into an eye through the perforation, a shackle near the opposite end having two flat portions and positioned astride the plate, a sprin adapted'to bear upon said flat portions to lock the shackle in a position of release and to confine the end of said. latch rod.

In testimony whereof I have hereunto affixed my signature.

CHARLES r. HUDGINS.
