ALOYSIUS WANEY, OF ST. LOUIS, MISSOURI, ASSIGNOR OF TWO-FIFTHS TO ROBERT BASILE, OF ST. LOUIS, MISSOURI.

LADDER SHOE.

Application filed September 11, 1920. Serial No. 409,578.

To all whom it may concern:

Be it known that I, ALOYSIUS WANEY, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Ladder Shoes, of which the following is a specification.

My invention relates to a ladder shoe, or antislipping device and, has for its object to provide a device which can be quickly attached to the lower end of one of the side rails of a ladder to permit the ladder to stand in an equalized position on a sloping roof, or other surface, without slipping or standing in a slanting position to one side.

A further object of the invention is to provide a shoe provided with spring members to frictionally hold the shoe to one of the rails'of the ladder when applied thereto.

A further object of the invention is to provide an extension leg having a bifurcated, or yoked lower end, one of the arms of said end being provided with a swivel foot provided with a rubber, or equivalent contact surface for use when standing on a slate, or tin roof, and, the other arm being provided with a pointed end for use when the ladder is standing on a sloping wooden surface, or its equivalent.

A further object of the invention is to provide novel means for holding the extension leg at any desired elevation, or adjusted position with relation to the shoe.

With the above and other objects in view, the invention consists in the novel features of construction, arrangement and combination of parts hereinafter fully described and finally pointed out in the claim hereto appended.

Referring to the accompanying drawings forming a part of this specification wherein like characters of reference denote similar parts throughout the several views:

Fig. 1, is a front elevation of a ladder equipped with a ladder shoe constructed in accordance with my invention, the same being shown as standing on a slanting slate, tin or equivalent roofing surface.

F ig. 2, is a view similar to Fig. 1, showing the ladder standing on a sloping surface such as wood, or its equivalent.

3, is a view of the device, partly in vertical sectional and partly inside eleva- Fig. 4, is a sectional View taken on line 4- 1 ofFig. 3. 1 In carrying out the aim of my present invention, I employ a ladder shoe 1 having an open top and a closed bottom 2 to prov de a ladder rail receiving socket 3. The front and rear walls 4 and 5 of the socket member are each provided with a leaf spring member 6 which springs are suitably fixed at their upper ends to the walls 4 and 5, as illustrated, their lower ends being free to y eld as the lower end of a ladder rail A is inserted into the socket 3. These spring members 6 yieldingly bear against opposite faces of the ladder rail A to hold the ladder shoe from slipping off of the rail A after the rail A has beeninserted into the socket 3, as is manifest.

The side wall 7 of the shoe is provided with a boss 8 which is provided with a longitudinal opening 9 to receive supporting leg 10. The supporting leg 10 is adjustable vertically within the opening 9 and is held in any desired position with relation to the shoe 1 by means of an eye-bolt 11 which is provided with a winged-nut 12. The eyebolt 11 is receivable in a transverse opening 13 in the side wall 7 of the shoe 1 and the supporting leg 10 passes through the opening of the eye-bolt. The eye-bolt engages one of the grooves 14 of the supporting leg and when the nut 12 is drawn down, the eye-bolt holds the leg 10 from slipping, as is manifest.

The lower end of the supporting leg 10 is provided with a forked end comprising two diverging arms 15 and 16. Arm 15 is provided at its lower end with a swiveling foot 17 which is provided with a rubber, or equivalent face 18 to prevent slipping thereof on a sloping slate, tile, or tin roof. The other arm 16 has its lower end tapered, or pointed, as at 19, to prevent slipping thereof on a sloping wooden, or equivalent roof, or similar surface. Both the foot 17 and pointed end 19 of the arms 15 and 16, respectively, are moved to a position in longitudinal alignment with the ladder rail A, when in service, as clearly shown in Figures 1 and 2, so that the end of the adjustable supporting leg 10 which engages the roof, or other surface upon which the ladder is standing, will come in alignment with the ladder rail A being supported, as is manifest.

It is evident, from the foregoing description, that my improved anti-slipping ladder shoe may be quickly applied to the side rail of a ladder and that it can be also quickly removed. It will be further observed that when the shoe has been applied to the rail and the ladder raised to its desired position, that the supporting leg 10 can be quickly adjusted to hold the ladder in a straight and level position without danger of tipping or moving side-ways, as it would were the shoe and extension leg not employed.

The many advantages of the herein de-- scribed ladder shoe will readily suggest themselves to those skilled in the art to whichit appertains, such as fire departments, garpenters, painters, tuckpointers, and the .ike.

I do not desire to be understood asv limiting myself to the exact details of construction and arrangement as herein described and illustrated, as it is manifest that variations and modifications may be made without departing from the spirit and scope of my invention and the terms of the following claim, hence I wish it to be understood that I reserve the right to make any such changes, or modifications as may fairly fall within the scope of the appended claim when fairly construed.

WVhat I claim is:

The combination with a side rail of a ladder; of a ladder shoe comprising a socket member having a transverse slotted opening in one of its side walls, a leaf spring fixed at its upperend'to the front and rear walls of the socket member and directed downwardly and inwardly within the socket member for frictionally engaging the front and rear faces of a ladder rail for normally holding the shoe upon the ladder rail, a boss formed on the side wall of the socket member having a longitudinal opening, an extension rod having spaced circumferential grooves receivable within the opening of said bossv and telescoping therewith, a screw threaded eye-bolt receivable in the transverse slotted opening of the side wall of the socket member, a nut for said screw-threaded eye-bolt for drawing the eye-bolt into engagement with said extension rod in one groove thereoffor holding the extension rod in its vertically adjusted position and the lower end of said extension rod being forked to provide two diverging legs, one of whichis provided at its free end with a swivel foot and the other being pointed at its free end.

In testimony whereof, I have hereunto signed my name to the specification.

ALOYSIUS WANEY.
