Application March 16, 1938, Serial No. 196,148

1 Claim. (Cl. 304-16) (Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) The present invention relates to safety appliances for painters and the like and it has a particular relation to a device for securing and slacking off the supporting line of a boatswains chair or stage.

One of the objects of the present invention is the provision of a device for connecting the supporting line with a boatswains chair or stage having means thereon for securing the line against movement and for snubbing the line when it is slacked ofi, the device being so located as to be accessible by the painter in the boatswains chair.

With this and other objects in view, as well as other advantages that may be incident to the use of the improvements, the invention consists in the parts and combinations thereof hereinafter set forth and claimed, with the understanding that the several necessary elements constituting the same may be varied in proportion .and arrangement without departing from the nature and scope of the invention, as defined in the appended claim.

The single figure of the accompanying draw- 1 ing is a side elevational view of safety device and boatswains chair, the supporting line being in a position to be slacked off.

Referring to the drawing, a safety device constructed in accordance with the invention is shown as comprising a vertical member or shank H! which is preferably formed from a bar the ends of which are bent upon themselves and toward one another to form upper and lower primary hooks l l and I2, the former being adapted to be connected with one end of a supporting girtline l3 and the latter being adapted to be connected with a sling or bridle M of a boatswains chair l5. The extremities of the hooks H and I2 are again bent upon themselves and away from one another to form spaced upper and lower secondary hooks l6 and I 1 around which the free end of the girtline I3 is: adapted to be looped and secured by a half hitch in order to maintain the boatswains chair in the desired working position. When it is desired to lower the boatswains chair the half hitch is released and the line held in the position shown in the drawing to permit an operator on the chair to slack away on the line with a snubbing action. The painter or other workman on the chair is thus enabled to control his descent himself as work progresses downwardly without the assistance of a helper below.

It will be observed upon reference to the drawing that the oppositely disposed secondary hooks E6 and H are offset with respect to each other in order that the loops of the girtline will not unduly bind upon each other and interfere with the operation of slacking ofi.

While the safety hook has been shown and described as being formed from a bar, it will be readily apparent that the member it may be in the form of a straight bar having eyes provided at its upper and lower ends and with a cleat or the like provided thereon for engagement by the free end of the line.

Other modifications and changes in the construction and arrangement of the parts may be made by those skilled in the art without departing from the nature and scope of the invention as defined in the appended claim.

The invention herein described and claimed may be used and/or manufactured by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.

I claim:

Safety appliance for painters and the like comprising a member having a pair of opposed hooks for connecting .a supporting line with a boatswains chair or stage, and oppositely extending hooks on said first mentioned hooks and disposed in offset relation relative to one another thereon around which the free end of the line is adapted to be looped to secure the same against movement and for snubbing the line when it is slacked away.

ED L. SORENSEN.
