VVILY SMALL, OF DALLAS, TEXAS.

SPECIFICATION forming part of Letters Patent N 0. 777,441, dated December 13, 1904:.

Application filed July 8, 1904. Serial No. 215,828. (No model.)

To ctZZ whom it may concern:

Be it known that I, WILY SMALL, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented a new and useful Roof-Anchoring Device, of which the following is a specification.

This invention relates to devices for guiding and supporting anchoring cables employed to hold the roofs of buildings for preventing their destruction by wind-storms, and has'for its object to provide a simplyconstructed and conveniently-applied device whereby the anchor-cables are guided and supported and prevented from injuring the roof and also to enable the strains to be distributed over a greater area of roof-surface.

With these and other objects in view,which will appear as the nature of the invention is better understood, the same consists in certain novel features of construction, as hereinafter fully described and claimed.

1n the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of the embodiment of the invention eapable of carrying the same into practical operation, it being understood that the invention is not necessarily limited thereto, as various changes in the shape, proportions, and general assemblage of the parts may be resorted to without departing from the principle of the invention or sacrificing any of its advantages, and the right is therefore reserved of making all the changes and modifications which fairly fall within the scope of the invention and the claims made therefor.

In the drawings thus employed, Figurel is a side view of a portion of a building with the improvement applied. Fig. 2 is an end view of Fig. 1. Fig. 3 is a perspective view of a portion of a hip-roof, illustrating the manner of applying the device to a roof of this character. Fig. 4 is a detached and enlarged perspective view from the under side of the guide-block. Fig. 5 is a perspective view, enlarged, of one of the base-plates. Fig. 6 is a perspective view, enlarged, of one of the guide-blocks viewed from above. Fig.

7 is a perspective view, enlarged, of one of the connecting or saddle plates.

The improved device is designed to provide means for supporting and guiding the anchorcables used upon buildings and similar structures in portions of the country subject to severe wind-storms, which frequently unroof buildings, and consists of a base-plate 10, havingmeans,such as screw or nail apertures 11, for attachment to the roof (represented at 12) and disposed in place of one or more of the shingles or slates at points where the cables (represented at 13) are turned downward through the roof to be conveyed thence to the ground or other permanent anchoring locality. The plates will preferably be of sheet metal and generally the size of a shingle or roofing slate or tile and will be built in with the shingle or slate to prevent leakage where the plates are located. Attached to each plate is a block 14, having a longitudinal groove 15 in its outer face and a transverse recess 16 in its side face. The blocks 14 may be mounted to swing upon the base-plate 10, as by a pivot-pin 17.0r attached rigidly thereto, as by two pins, one of which is the pin 17, and with another pin 18 employed in addition, as hereinafter explained. A certain number of the plates 10 will also be connected by saddle-plates 19 for hanging-over the ridge portion 20 of the roof to guide and support the cables passing thereover.

With a supply of the base-plates 10, provided with the screw or nail apertures and spaced apertures for the pins 17 18 and a corresponding supply of the blocks 14, together with a certain proportion of the plates 10, connected by the saddle-plates 19, any size or form of roof may be readily equipped with the holding-cables and without change in the structure of any of the parts. If the roof to be protected is of the plain straight form having an uninterrupted ridge portion 20, a number of the plates 10 will be secured along the roof near the eaves 22 at suitable distances with the blocks 14: secured rigidly thereto by the two pins 17 18 and a corresponding number of the plates connected by the saddle members 19 placed over the ridge portion 20. Holes are then drilled through the plates 10 at the lower ends of the channels 15 and continued through the overhanging eaves 22 of the roof, through which the cables 13 are conducted to their anchorage at any suitable point in the ground to the walls of the building or to other permanent support and likewise carried over the roof and through the channels 15 in all the blocks in transverse alinement. The blocks thus firmly support the cables and prevent lateral movement thereto and also prevent short bends in the cables, which might cause fracture under the severe strains to which they are subjected, while at the same time the relatively large base-plates firmly support the blocks and distribute the strains over an extended area of the roof. If the cables are to be attached to irregular forms of roofsthose, for instance, having hips, gables, and the like, as in Fig. 3the plates having the saddle members connecting them will be employed in the same manner upon the ridge portions; but as the lengths of the eaves in roofs of this character are greater than the lengths of the ridge portions a greater number of the plates and their blocks will be employed along the eaves than along the ridges. The blocks 14, which come in alinement with the several ridge-blocks, will be secured rigidly to their respective plates by the two rivets 17 18 and the cables 13 carried over them and anchored, as before described. The surplus blocks at the sides will be pivotally connected at their respective plates 10 and shorter cables, as at 23, looped around the blocks 14 at theridge portions of the roof within the recesses 16 and carried thence over the pivoted side blocks at the eaves and down through the same, as before described. It will be obvious that the shorter cables 23, extending at angles from the blocks at the ridges, pass to the channels 15 of the blocks at the eaves at corresponding angles. Hence the necessity for pivoting the blocks to permit them to be turned to the same angle to insure the proper direct draft to the cables. In this connection also the holes for the cables will not be drilled in the plates 10, carrying the swiveled blocks, until the degree of angularity is ascertained to secure the requisite accuracy of position of the parts.

By this simple means it will be obvious that a very convenient and eflicient support and guide is provided by means of which the anchor-cables may be carried over the roof in any desired direction and without injury to the roof or building or danger of weakening the cables.

The blocks and plates will be preferably galvanized or otherwise protected from corrosion, and the cables will also be preferably of galvanized steel or iron.

Having thus described the invention, what is claimed is 1. As a new article, a block having means for pivoting to a base-plate and provided with a longitudinal groove in its outer face and a transverse recess in its side face.

2. As a new article, a block having a longitudinal groove in its outer face and a transverse recess in its side face, said block being provided with one or more apertures extending through the block from the bottom of said longitudinal groove and adapted to receive fastening devices.

3. The anchoring device herein described consisting of a base-plate having means for attachment to a roof, a guide-block having means for attachment to said base-plate and formed with a longitudinal groove in its outer face and a transverse recess in its side face, and a cable anchored by the ends and leading over said block within said longitudinal groove.

4. The anchoring device herein described consisting of a base-plate having means for attachment to a roof, a guide block having means for attachment pivotally to said base-plate and formed with a longitudinal groove in its outer face, and a cable anchored by the ends and leading over said block within said longitudinal groove.

5. The anchoring device herein described consisting of a base-plate having means for the attachment of an angular extension for engaging the ridge member of a roof, a guideblock having means for attachment pivotally to said base-plate and provided with a longitudinal groove in its outer face, and a cable anchored by the ends and leading over said block within said longitudinal groove in the same.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

WILY SMALL.
