Description

Jan. 20, 1931. E. E. wlNELAND ROOF CLIMBING DEVICE Filed June 24, 1929 ATTOR NEY Patented Jan. v20, 1931 UNITED STATES EMERY E. WINELAND, F COLLEGE VIEW, NEBRASKA ROOF-CLIMBING DEVICE Application filed .Tune 24,

This invention relates to a roof climbing device, the general object of the invention being to provide a member having a strap thereon whereby one of the members can be attached to each leg of a person below the knee, with pointed projections on the member so that a person, such as a fireman, can readily climb a pitched roof without danger of slipping thereon, even though the roof is v covered with ice.

This invention also consists in certain other features of' construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out inthe appended claim.

In describing the invention in detail, reference will be had to the accompanying drawing wherein ylike character denote like or corresponding parts throughout the several views, and in which Figure l is a view showing how the device is used to climb a roof.

Figure 2 is a section on line 2-2 of Figure 4.

Figure 3 is a section on line 3 3 of Figure 4. 1

Figure 4 is a bottom planview of the de vice.

In these views, the numeral l indicates a plate of metal with its side edges turned np, as shown at 2, to provide flanges and pointed projections 3 extend from the outer face of the plate, these projections being "f preferably formed by cutting the metal and bending the metal between the cuts outwardly, as shown. Each projection is formed by the metal bent from a pair of cuts.

40 i` A pad 4 is placed on the inner face of the member and is preferably attached thereto by bending the edges of the Hanges over the edges of the pad, as shown. One end of a strap 5 is passed through openings formed in one side of the member at the 'center thereof and in the pad and then this end of the strap is fastened to another portion of the strap. The other end of the strap is provided with holes for receiving a tongue of a:

buckle 6 carried by a strap v7 which is fas- 1929. Serial No. 373,449.

tened to the opposite side of the member ,l and pad, as is the strap `5.

@ne of these members is attached to each leg of the user below the knee, as shown in Figure l, so that when the user climbs ar roof, the points on the plate l will engage the roof and thus prevent the person from slipping even though the roof is coated with ice or is slippery from being wet. As will be seen, the devices will not interfere with a person walking.

The invention is mainly designed for firemen, though it will, of course, be understood that it can be used by other persons climbing a roof.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changesmay bev y made 'in the construction and in the combi- 70 nation and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

yWhat I claim is A roof climbing device comprising a sub- '75 stantially rectangular platerhaving the side edges turned upwardly and inwardly over the main portion thereof, a pad overlying the plate and' disposed under the flanges to engagea persons leg, teeth on said plate, said S0 flanges having slots intermediate their ends, and a leg strap received by the slots to secure the pad against the leg with the plate disposed outermost.

In testimony whereof I affix my signature. 35
