"1 race WINDOW-QLEANEB'S LIFE BELT.

' Specification of Letters Patent.

Application filed January 13, 1?);5. fierial No. 2,079.

To all whom it may concern:

Be it known that I, WV LB RT C. FAWKns, a citizen of the United States, and a resident of Portland, county of l/lultnomah,-

State of Oregon, have invented a new and useful Improvement in Window-Cleaners Life-Belts, of which the following is a specification.

My invention relates to devices used by window cleaners for fastening life-belts to the sides of the window.

The object of my invention is to provide an inexpensive device readily applied to use, and which will insure the safety of the user under all conditions. So many of these devices have a tendency to become unfastened when used in connection with a stiff strap; others have weak parts which are liable to break under a sudden stress. In my device these conditions are avoided.

My device furthermore permits freedom of motion to the user; the connections being arranged to work on the principle of a universal joint.

The details of construction and operation of my device are hereinafter fully described, reference being had to the accompanying drawings as constituting a part hereof.

In these drawings, Figure 1 is a plan section showing a window, the casing of which is provided with headed bolts, and on the latter are fastened the socket block provided at each end of my improved life-belt. Fig. 2 is a sectional diagrammatic view illustrating both the construction and method of operation of my invention; the numerals I, II and III designating the first, second and third positions which my improved socketblock assumes while being fastened on the headed bolts, as in practice. Fig. 3 is a sectional view showing a convenient type of headed-bolt which I prefer to use with my invention; Fig. 4 is a cross-section taken on the line of the arrow 4, in Fig. 3; Fig. 5 is a side elevation of my improved socket block; Fig. 6 is a cross-section taken on the line 66 of Fig. 5: Fig. 7 is a view of the under side of my socket block; Fig. 8 is a view of the top side of my socket block; Fig. 9 is a longitudinal section of my socket block, and Fig. 10 is a fragmental view similar to Fig. 8, but showing an alternate construction of the means for attaching the socket block to the 1ife-be1t.

Y My invention consists of a socket-block having an elongate body (1, consisting of sides 5, c, spaced apart by an integral, perpendicular, longitudinally extending, medial web, (Z, the location and arrangement of which is more readily seen from Fig. 9. The left end Z)" of the web, merges into the body of the socket, as shown in Fig. 9, which construction is adapted for the purpose of giving strength to that portion of my socket block where the heaviest strain is sustained.

On the inner faces of the sides I), c, are perpendicular flanges c, f; the space between the sides and the flanges constitutes a flanged slot, as more clearly shown by Fig. 6. This slot extends all around one side and to both the ends 9, g and extends around the end 9' and for part of the length of the under side, as at h. The flanges e, f, are made with an enlargement, as at i, to receive the head of the bolt driven in the wall, represented by j in-Fig. 2.

I find it convenient and I prefer to use the type of bolt shown by j in Figs. 3 and 4. It is made of two parts, 76, is, having serrations as Z, and chambered at m, to receive a tapering wedge 11, which is driven inward in the chamber m by some convenient instrument inserted through the cavity, 0, of the head. The forcing of the wedge inward spreads the serrated ends of the bolt-part k, it apart, and thus locks the bolt in place. To prevent the bolt-parts 7a, 70 from having lateral movement on each other, I make the part is with lugs 72, and the part is with centering holes for said lugs, as shown at 79, Fig. 4. To the sides of the socket block a, there is hinged on trunnions s a elevis r made with a tongue, 9, to which is riveted the end of a strap, a, as shown more clearly in Fig. 9.

The manner of use of my invention is illustrated in Fig. 2. In fastening my socket block to the bolt, the under side of the socket with the enlargement i is first slipped over the head of the bolt, j, as illustrated by the first position I, the socket block is then turned to the second position II and by moving same in the direction pointed by the arrow shown in connection with position I; the movement of the socket block is then con- When finally so arranged, the socket may be Patentgetlt Dec. Mt, 1915. I

freely moved in all directions Without danger of becoming disconnected from the bolthead. i i

The usual form of life-belt is shownhy of the form shown in the other figures, but

instead of the hinged elevis g, a fixed clevis t, is made integral with the body of the socket block. The strap r is then riveted on the cross-bar of said rigid clevis t, and is adapted to hinge upon said cross-bar.

I claim:

1. In a device-of the character described, a socket block consisting of an elongate body having a recess extending the entire length of one side and to both ends, and around one end and part of the lengthof the other side, flanges overhanging both of one side and to both ends, and around one end and part of the length of the other side, flanges overhanging both sides of said recess the flanges overhanging the shorter length of the recess being cut away near the terminus of the latter to receive the flaring head of a bolt, a clevis hinged to the sides of the socket, and a strap fastened to such clevis.
