ROOF WORKERS SAFETY DEVICE Filed Dec. 12, 1939 INVENTOR. fi/vmamm/ Gut/it BY 7 ATTO Patented Feb. 18, 1941 UNITED STATES ATENT OFECE 1 Claim.

This invention relates to safety appliances and more particularly for workmen engaged in repairs, paintin and the like on the slanting roofs of ordinary buildings.

The danger of working on such roofs is well known, and if in a slippery condition the peril is greatly increased.

To construct scaffolds whereby a measure of safety is attainable, is not only expensive as to material and time taken, but is likely to cause damage to the roof by the fastening means used.

It is therefore an object of this invention to provide an essentially simple safety device, applicable to all types and angles of sloping roofs, whereby safety is obtained for the workmen operating on them.

A further feature is in the provision of an in expensive device, for each workman, capable of being readily moved and adjusted as may be desired and which cannot injure or deform the roof in any manner.

Another purpose is to produce a safety device applicable alike to all kinds of roofs, as shingle, tile, slate or others, that affords a full measure of security.

These highly meritorious objects are accomplished by the novel and practical construction of few and simple parts hereinafter described and illustrated in the accompanying drawing, constituting a material component of this disclosure, and in which:

Figure 1 is a perspective view of the device showing the several features in detail.

Figure 2 is a fragmentary perspective view graphically indicating its application.

In the drawing a conventional type of building is designated by the numeral l5 having a window It and roofs l'll8 slanting equally downward from the central ridge IS.

The invention consists of a strong bag 20, made of canvas or like strong woven fabric and filled with a weighty granular substance, such as sand, easy and inexpensive to obtain.

The bag is preferably provided with a wide tie band 2| encircling the center of its length,

and a central lengthwise band 22, these bands being preferably secured in their adjusted positions by stitching to the bag, as at 23, before filling.

Fixed to these bands, and at the sides and edges of the bag, are metal loops 24, to .any of 5 which may be removably engaged a snaphook 25, its opposite end being united to engage one of the ends of the flexible wire or other rope 26, of such length as to extend at least to the eaves of the roof.

The opposite end of the rope may be attached to a similar snaphook Z1, and at spaced distances along its length are fixed hand grips 28', which, if desired, may be engaged by the eye 21, thus forming a coil which can be used to encircle the body 15 of a person, as indicated in Figure 2.

In operation one of the heavily filled sand bags 2i! rope it is allotted to each workman, the bag disposed on the side of the roof opposite where the work is to be done, and the rope passed 20 over the ridge to the operator, thus enabling him to use the coiled portion as a girdle and the hand grips as occasion requires.

It will be obvious that due to the weight of the sand bag and its frictional resistance on the roof to an upward pull, a persons weight may be safely sustained, the bag acting as a secure anchorage, but which may be shifted along the roof to any desired point.

The simplicity and security afforded by the device are thought obvious.

Having thus described the invention as set forth the manner of its construction and application, what is claimed as new and sought to secure by Letters Patent, is: I

A roofers safety appliance comprising a heavy sand bag having opposed flat frictional surfaces, longitudinal and transverse bands fixed in crossed relation centrally on said bags, loop eyes fixed in said bands at each of the four edges of the bag, a flexible rope having snap hooks at its ends to connect with said loop eyes selectively, and hand grips intermediate the length of the rope to which one of the snap hooks is selectively engageable.
