The device of the invention serves to prevent slippage or other undesirable movement of the ladder when placed in such position for use. The device is constructed at one end thereof to embrace one of the side rails of the ladder, intermediate a pair of adjacent rungs near the upper end of the ladder, and is provided at its other end with means to straddle one of the spikes or similar members that are normally present for securing the roof gutter to the eave of the roof.，下面是Ladder supporting device专利的具体信息内容。

权利要求

1. A safety device for securing a ladder in leaning position against a vertical surface of the wall of a house or like structure, with the upper end of the ladder reaching above the roof gutter, said device comprising a relatively elongated rightangular bracket having means adjoining one end thereof formed to encompass a side rail of the ladder, means on said bracket for clamping the same to the opposite side faces of said rail, the opposite end of the bracket being disposed in a plane extending substantially at a right angle to the elongated direction of the bracket, said opposite end being bifurcated so as to be capable of straddling one of the spikes normally used for securing the roof gutter to the eave of a roof.

2. A safety device as defined in claim 1, wherein said clamping means comprises a pair of spaced bolts each having their opposite ends screw threaded, one end of each of said bolts having a head thereon and the opposite end of each thereof carrying a screw threaded wing nut.

3. A safety device as defined in claim 2, wherein one of said bolts is provided with a coil wire tensioning spring.

4. A ladder safety bracket for attachment of a side rail of a ladder to one of the spaced spikes securing a roof gutter to an eave of a roof, said bracket comprising: a. a first leg; b. a second leg disposed in parallel relation to said first leg and having one end thereof terminating in a flange portion to form the second leg into an L-shape, said flange having a forked portion extending downwardly therefrom for engagement with said spike; c. a pair of freely rotatable roller aSsemblies spaced from one another along the length of said legs and disposed between the opposing faces of said legs, each said assembly comprising a coil spring and cylindrical sleeve surrounding the coil spring, said coil spring surrounding a bolt or pintle having its ends fitted into transversely aligned openings in said legs.

5. The device as defined in claim 4, wherein said assemblies provide means for varying the spacing between said legs, whereby to enable said device to encompass ladder rails of various thicknesses between the said legs.

6. A ladder safety bracket for securing a rail of a ladder to one of the spikes attaching a roof gutter to the eave of the roof, said bracket comprising: a. A U-shaped member having one long leg and one short leg, said long leg terminating in an L-shaped flange portion, said flange portion having a forked portion extending downwardly therefrom for engagement with one of said spikes; and b. a pair of roller assemblies, each assembly having a threaded pintle, a coil surrounding said pintle, and a sleeve loosely encasing said spring and the pintle surrounded thereby.
