F. S s E .N H W ATTORNEY UNITED STATES Pres-e1 Specification of Letters Patent.

Patented April 24, 1906.

Application filed November 17, 1905. Serial No. 287,915.

To all whom, it may concern:

Be it known that I, WILLIAM B. MORE- woon, a citizen of the United States, and a resident of Elizabeth, Union county, New Jersey, (and whose post-office address is 253 Broadway, New York city,) have invented certain new and useful Improvements in Supporting Devices, of which the following is a specification.

This invention relates to supporting devices and to such as are more particularly designed and adapted to support a man when cleaning or repairing a window.

The invention consists of the features hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, forming part of this specification, and in which like reference-numerals designate corresponding parts, I have shown the preferred embodiment of my invention.

Figure l is a perspective view showing the device connected in operative position. Fig. 2 is a plan view of the supporting-clip, showing a bolt in the relativeposition to the clip necessary for the removal or application of the clip. Fig. 3 is a longitudinal elevation of the supporting-clip. Fig. 4 is a sectional longitudinal elevation of the clip and a bolt such as is illustrated in Fig. 2.

Referring now more particularly to the details of the structure shown in the drawings, 3 and 4 are the walls of a building, while -5 and 6 are the corresponding sides of a window-casing on either side of a window 9.

1 and 2 are-bolts, similar to the bolt illustrated in Figs. 2 and 4, seated in the windowcasing.

7 is a supporting strap or cord attached to two similar supporting-clips 23 24, which are respectively in engagement with the bolts 1 and The strap or cord 7 is attached to asupporting-belt 8 by means of guides 25 and 26.

The supporting-clip is shown in detail in Figs. 2, 3, and 4, in which 12 is a substantially flat strip or web of metal completely inclosed by an integral reinforcing-margin 11, which is raised from the surface of the strip. This margin not only allows the clip to be made from a minimum amount of material, butadds finish and strength to the clip.

One end of the clip terminates in a circular portion 13, which is turned up at an obtuse angle to the body of the clip and is provided on its lower face with a rounded or convex seat 14. The circular contour of the end 13,

V on? I aided by the convexity of the seat 14, allows free movement of the clip and prevents the end of the clip from looking against any irregularity on the window-casing or on the wall of the building, to which the bol ts 1 and 2 are sometimes attached. The bolts 1 and 2 may be ordinary commercial stock bolts and need not be specially designed.

18 is a square bolt-head opening passing through the inner end of the strip 12 and is disposed with a diagonal extending length- Wise of the strip. 'A slot 16 of sufficient width to receive the shank of the bolt 21 extends lengthwise through the strip from the bolt-head opening 18 to a rounded wall in the center of the circular turned-up portion 13. A portion of the strip 12 is cut away at 19 adjacent to the reinforcing-margin at the end of the stri This margin is turned up or offset from t e body of the clip at 22, and the end portion 20 forms a smooth round strap-attaching bar.

The clip may be cast or may be stamped out of sheet metal.

In order to apply the cli to a bolt, it is first necessary to turn the c ip in the relative position to the bolt-head, as is illustrated in Figs. 2 and 4, or at right angles thereto, when the bolt-head 17 may be passed through the o ening 18 and the shank 21 pass up through t e slot 16 into engagement with the wall 15, when the head 17 is locked in the clip by the strip 12.

It is obvious from Fig. 1 that when the bolt is applied in operative position the clips are turned relatively to the bolts, so that if by accident they should slide up from the shanks of the bolts it would be impossible for them to disengage the same, as the bolt-heads 17 could not pass through openings 18, because their faces would not aline with the walls of the openings. The position of the bolt-heads relative to the walls of the building and the position of the square opening 18 relative to the clip 10 might be modified from those illustrated so long as their relative position when the device is in use would prevent acoidental disengagement of the clip. However, it is preferred to locate the square opening 18 with a diagonal disposed lengthwise of the clip, so that the Walls of the opening 18 form inclined guides to deflect the shank of the bolt into the locking-groove 16 as soon as the bolt-head has passed through the opening 18.

The clip is turned up at both ends, so that the strain of the supporting-strap may be adreceiving slot extending from the bolt-head vantageously applied to the bolt and so that opening to a rounded Wall in the center of the the clip may possess greater freedom of movecircular portion. ment upon the bolt. 2.
