ANTISLIPPING DEVICE FOR LADDERS.
Substitute for application Serial No. 135,165, filed December 5, 1916. This application filed January 21,
To all whom it may concern:
Be it known that I, WALTER A. HEARN, a citizen of the United States of America, residing at Baltimore city, in the State of 5 Maryland, have invented a new and useful Improvement in Antislipping Devices for Ladders, of which the following is a specification.
My invention relates to improvements in 10 anti-slipping devices for ladders, the objects of which. are first, to provide a device for preventing the slipping of ladders when used on ice or similarly covered surfaces; second, to provide a separate fixture from the ladder which can be carried or sold independently of the ladder; third, to provide an anti-slipping device which permits the angle of the ladder to be reversed, and having fixed depending legs for gripping the iced or slippery surfaces. I attain these objects by the device illustrated in the accompanying drawing, in which- The figure represents a perspective view of my anti-slipping device, illustrating the leg of a ladder inserted in the socket and Serial No. 3,890.
the reversed position of the said leg indicated by dotted lines, in my anti-slipping device.
Referring to the drawing, the numeral 1 designates the leg of a ladder; 2 indicates 30 the rung; 3 is a hollow rectangular oblong socket closed at the bottom a and having depending tapering legs 5. 6 is a hole bored or cast in the side for tying or carrying my anti-slipping device.
I do not care to limit myself to any particular construction or shape of either the socket or the legs depending from the socket.
What I claim is- An anti-slipping ladder-foot attachment 0 ment, comprising a multiple sided socket provided with a suitable bottom and provided with an areato substantially lit the sides of the stile of a ladder while being long enough to permit the stile to occupy different tilted 45 positions with the end of the stile in engagement with the bottom of the socket, said socket having elongations of its vertical corners below the bottom to form prongs.
WALTER A. HEARN.
