UNITED STATES BENJAMIN KUGLER, OF CHICAGO, ILLINOIS.

I A rocxnn ANCHORAGE ron WINDOW-CLEANERS HARNESS.

Application filed February 19, 1923. Serial No. 619,978.

dow-Cleaners Harness, of which the fol-- lowing is a specification.

My invention relates, in its broad aspect, to a fixed and positively locked anchorage for window cleaners harness, which is particularly adapted for use with a wooden base.

More particularly my anchorage isdesigned to provide a positive means for engaging into the material offa base whereby to prevent disengagement of the anchorage therefrom due to over-loading or weakening of the material of such base.

In attaining the objects of my invention I employ a plurality of inherently resilient members forming tangs, which are swingable, and adapted to normally extend without the surface of the shank of an anchorage, but compressible within suitable recesses provided for that purpose in the shank. In practice it has been found that certain materials, and particularly wood, do not afford suiiicient resistance to stress and strain, and weathering, to insure a permanent and safe attaching base for an anchorage for window cleaners harness. For the purpose of surmounting this difiiculty, I have devised the hereinbefore defined anchorage, the tangs of which are adapted to embed themselves in the material of the base, and exert a relatively greater resistance to withdrawal as the stress upon the anchorage is increased, or as the material of the base becomes weakened through age, weathering, or the like.

The structural elements employed to accomplish the above and other results and objects will .be hereinafter more fully described in detail andspecifically pointed out in the claims appended hereunto and forming a part of this specification, but the scope of the invention may only be determined by the limits defined in the claims.

In the accompanying drawings, wherein is illustrated the preferred embodiment of my invention Figure 1, is a side view of the principal embodiment of my invention,

Figure 2, is a front view thereof, Figure 3, 1s a sectlonal view of the shank of the anchorage.

Like characters of reference refer to like or similar parts throughout the several views" ofthe drawings, in which The numeral (1) designates the head of my anchorage, which in the present instance is elongated and has a drilled opening (2) formed adjacent toone of its ends for the purpose of receiving a screw or the like (not shown) to prevent possible turning action of the head under the stress exerted by a window cleaners harness. Integrally formed upon the head (1) are a pair of spaced studs (3). The studs are reduced intermediate their lengths for the purpose of receiving a. window cleaners harness coupling of the type described in my patent Number 1,442,- 159, issued January 16th 1923, and in my patent Number 1,449,516 granted March 27, 1923, upon a combined catch and slide anchorage. j

Formed integrally with the head and extending at an obtuse angle, or diagonally, therefrom is a shank (4) which is cut-away as at (5)(5) adjacent the head, to form opposed reduced and flattened surfaces. An opening (6) is formed through the shank at the end of the reduced portion nearest to the free end of the shank, and trained through this opening is a substantially U-shaped, inherently resilient member forming tangs (7). The tangs are compressible to lie fiat upon the fiat surface of the shank, but the member as a whole is swingable in a semicircle to engage into the substance of a base (not shown) into which the shank is projected. It being understood that the shank as a whole is to be projected into a wooden or other base to mount the anchorage thereon.

The shank (4:) is further provided with a pair of opposed groves (8)(8) between the reduced portion and the free end thereof, and it will be noted that the grooves are arranged in the sides of the shank at rightangles to the cut-away portions (5)-(5). Drilled through the shank at the ends of the groves nearest the free end of the shank is an opening (9) through which a second U- shaped, inherently resilient member forming tangs (10) is trained, and while this member 'bite into the material, of the base and positively lock the anchorage. Furthermore, if

the material of the base is wood, and through the deteriorating elfect oi age, or weathering it becomes weakened, the tangs will bite into the material and prevent accidental dislodgjment of the anchorage.

. It is here pointed out that the stress and strain upon the anchorage by the weight of a person in harness attached thereto will tend to more securely lock the anchorage upon the base in dlrect proportion to the amount of weight, or the load, placed upon l/Vhile in the foregoing, there has been described and illustrated such combination and arrangement of elements as constitute the preferred embodiments of my anchorage,

it is nevertheless desired to emphasize the that interpretation of the invention shouldonly be conclusive when made in the light of the subjoined'claims.

Havingdescribed my invention and its l/Vhen the anchorage is subhereto.

objects with such attention to detail as will thoroughly acquaint one skilled in the art with its construction and advantages, I claim 1. An anchorage for window cleaners harness comprising a head and a shank, a plurality of swingable members carried by the shank, and means formed on the shank for variably limiting the relative swingability of said members for the purpose set forth.

2. An anchorage for window cleaners harness comprising a head and ashank, a plurality ofswingable members carried by the shank, and each arranged to swing in an arc medially lntercepted by a line defining the longitudinal axis of the shank, and

means formed on the shank for variably limiting the relative swingability of said members for the purpose defined.

3. An anchorage for window cleaners harness comprising a head and a shank, said shank formed with grooves adjacent its free end, and flattened portions between the grooves and its head, the web of the flattened portions being longitudinally aligned with the grooves, and a plurality of swingable anchoring means one 01 which is seatable in the grooves and the other upon'the flattened portions for the purpose defined.

In testimony whereof, I my signature BENJAMIN KUGLER.
