To all whom rlt may concern;

Be it known that 1.,BENJAMIN Known, a c t zenof the United States, residing at ,Qhicago, in the county of Cook and State of Illinois, have invented new and useful 1mplovements in'Dritled Base rtnchora-gefor 'Window-Gleaners Harness, of which the following is a specification.

.My invention has reference to improvements in anchorages for window cleaners harness, and has particular reference to an anchorage of this type which is adapted to form a permanent fixture upon a. building;

and as defined herein the anchorage includes a drilled base embodying a plurality of novelly formed and arrangedstuds for the reception of couplings carried by the supporting straps of the harness of a window cleaner.

The utilization of lag screws and the like fixed in each side of a window casing has been'found impractical for the reason that the heads of such screws, about which the anchorage.

the harness couplings are attached, soon become worn, and consequently fragile,

through lateral stress and the continued turning action to which they are subjected by the couplings. Furthermore, the threads of such screws, as well as the heads, become rusted or corroded, thereby increasing the danger of their suddenly giving way or pulling out.

Mypresent invention, on the other hand, modifies the effect of lateral stress and prevents turning action of the coupling upon Furthermore, the means used in attaching the base to the building are subjected to no lateral stress or strain, nor are they directly engaged by the harness couplings; and the shanks of such attaching means, whether they be bolts or screws, are protected by the bodies of the anchorages from the corrosive action of the weather.

The structural elements employed to accomplish the above, and other results and objects, will be hereinafter more fully described in detail and specifically pointed Figure 3,.is a sectional view taken on the line .3-.3 of Figure 1, and

Figure 4, is an end view.

Like characters of reference refer to like or similar parts throughout the several views of the drawings, in which (A) designates the base of my anchorage, which has drilled'openings adjacent its ends as at ('1) for the reception of attaching screws, belts or the like (not shown). The base, in the present instance, is elongated and has rounded ends. Rising from the sides ofthe base (A), and inclined laterally and toward the ends thereof, from the approximate center of the base are web members or legs The legs are arranged in complementary pairs and increase in thickness, but decrease in breadth toward their ends, while the portions of eachpair of legs approachincr their bases are connected by a web Each leg is reduced, as at (4:), adjacent its end, and then enlarged to form a head (5), which will hereinafter be termed a stud.

It will be noted that the legs (2) composing the respective pairs, are flaredlaterally from opposite sides of the base, and that they are then formed to dispose the studs (5) in the same relative plane, so that the couplings, such as are described in my Patent fish 1 ,42,159, issued January 16th, 1923, may be afiixed thereto. Furthermore, the respective pairs of studs are inclined toward adjacent window casings thereby modifying lateral stress exerted by the weight of a person upon the harness.

It is here pointed out that the peculiar disposition of the legs (2) with respect to the base (A) greatly modifies the strain upon the attaching means (not shown), and such attaching means, when disposed through drilled openings (1) are partially enclosed by the legs and the webs (3), thereby reducing the deteriorating action of the weather and the like.

In use, my anchorages are preferably attached between adjacent windowsdouble windows-thereby disposing the respective studs toward the approximate lines of stress exerted by the harness of a window cleaner, and it ill be noted that when two window cleaners are operating upon adjacent windows at the same time,'the stress exerted by each of their harnesses upon the same anchorage will be equalized one by the other. WVhile in the foregoing, there has been described and illustrated such combination and arrangement of elements as constitute the preferred embodiment of my invention, it is nevertheless desired to emphasize the fact that interpretation of the invention should only'be conclusive when made in the 7 an opening therein to receive a headed securing element, studs disposed one to either side of said opening whereby a Window cleaners harness may be attached to the anchorage, and webs connecting said studs with the end and side edge portions of the body wherebyto provide a protective pocket to receive the head of the fastening element. 3

2. An anchorage for window cleaners harness comprising a'body portion having openings therein to receive headed securing elements, oppositely inclined pairs of studs disposed to extend from the ends oi' said body portion, webs connecting said studs with the body portion at the sides thereof, and the studs comprising each pair being arranged one to either side of an adjacent opening and disposed to overhang the sides of the body portion, other webs connecting the studs comprising each pair with the adjacent end portion of the body, said side and end webs forming protective pockets to receive the heads of the fastening elements. .7

In testimony whereof, I ailiX my signa ture hereto.

BENJAMIN KUGLER.
