J. J. HUSSEY July 25, 1961 LADDER PAD Filed NOV. 17, 1960 as FIGZ INVENTOR JOHN J. HUSSEY fwfl? FIG?) ATTORNEY s4 II llllllllhh United States Patent 2,993,562 LADDER PAD John J. Hussey, Hudson, Mass. Frohock-Steward 'C0., 79 Beacon St.,

, r 7 Worcester, Mass.) Filed Nov. 17, 1960, Ser. No. 70,065 9 Claims. (Cl. 182214) This invention relates to a new and improved ladder pad, the general object of the invention residing in the provision of a pad member detachably mounted on the side rails of a ladder or the like, said member forming a cross piece which may bear against the side Wall of a house or other building when the ladder is erected so as to prevent the ends of the ladder rails from impinging upon the wall and damaging or marring the same, the ladder pad essentially being interposed between the ladder rails and the side wall.

Another object of the invention resides in the provision of a device of the class described having means for clamping the pad to the ladder rails, said clamping means having' a limited degree of rotary motion relative to the pad so that the ladder may be clamped but at the same time has an angular adjustment with respect to the vertical so that the lower ends of the rails of the ladder may be positioned at an adjustable degree of distance from the bottom of the Wall against which the ladder is erected; and the provision of adjustable clamping means for the ladder pad with respect to the rails as aforesaid, the same being easily manually tightened and loosened by the operator to firmly clamp the pad to the ladder while still allowing for the slight degree of angular adjustment which may be required for unevenness of ground, different heights at which the ladder is to be extended, etc.

The invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly set forth in the appended claims.

Reference is to be had to the accompanying drawings, in which FIG. 1 is a View in elevation illustrating the device in FIG. 2 is an enlarged view in elevation of the ladder p FIG. 3 isan enlarged plan view of a part of the ladder pad looking in the direction of arrow 3 in FIG. 2, and

FIGS. 4 and 5 are enlarged sections respectively on the lines,44 andjees in FIG-.3. I

.Incarrying out the present invention, the same is shown asapplied to a conventional ladder having side rails 1'0 and 12 spaced in .the usuaLmanner by .the connecting ;The .pad itself comprises preferably a fiat member 14 whichofcourse can be. made of any suitable material, this. memberhaving .a. length greater than the width between the. rails 10.and 12-a11d mounting on one facethereofa pair .of alignedlaterally. adjustable plates generally. indicated at 16.. These plates are substantial ly the same and..are .provided with longitudinal aligned slots 18, 18 ,through. which. project fasteners generally indicated at 20, 20 for holding the plates in longitudinally adjusted position on the pad member 14.

- Intermediate the ends of each plat 16 there is provided a Q shaped bracket member; generally indicated .at 2215a secured to its plate at its closed end. Each bracket is provided with spaced outstanding legs 24, see particularly FIG. 3. The legs 24 are apertured and receive a cross fastener 26. This cross fastener is preferably a threaded member and it has a washer 28 at one end thereof and a head 30 at the same-end. The fastener 26 extends through the other leg 24 of the U-shaped bracket 22 and is provided with a loose collar 32, which bears on a washer 34, see particularly FIG. 5. At the end of the H v 2,993,562 Patented July 25., 1961 fastener 26 there is a wing-nut or the like indicated at 36 by which means collar 32 may be moved along the fastener as will be clear from inspection of FIG. 5.

Within the legs 24 of each bracket 22 there is provided an elongated U-shaped member generally indicated at 38 having legs 40, 40, the same being apertured near their ends for the reception of the fastener 26 as clearly shown. The two U-shaped members oppose each other as clearly seen in FIG, 3 and the rails 10 and 12 of the ladder are received in the opening between the legs 4040 and fastener 26. The washer 34 bears, on one leg 40, the other leg 40 hearing on a washer 42, see FIG. 3, this washer being interposed between the leg 40 and adjacent leg 24 of bracket 22.

The ends of the legs 40 of the U-shaped members 38 are formed at an angle, see particularly FIG. 4, as indicated at 44, thus forming bearing corners 46 and 48. Either one of these corners bears against the closed end of bracket 22, see FIGS. 3 and 4, depending upon the rotative or oscillatory position of members 38 with re spect to the fastener 26. This motion will be seen to be very limited as the members 38 can move only between the solid line and dotted line positions in FIG. 4, but this limited motion is suflicient to provide for an adjustable inclination of the ladder with respect to the wall against which the pad is abutted, depending upon the length of the ladder, the extension thereof, inequalities in the ground, etc., and the corners at 46 and 48 provide means limiting the swinging action thereof so that the pad is always presented to the wall generally flatly regardless of the relative inclination of U-shaped members 38 With regard to the brackets and the pad.

In order to clamp the ladder rails, it is only necessary to turn the thumb pieces 36 so as to move collars 32 to the right causing leg 40 in FIG. 5 to be moved inwardly to clamp the rail of the ladder.
