HENRY GOLDENFARB, OF LONDON, ENGLAND.

SAFETY APPLIANCE FOR USE IN CLEANING WINDOWS.

SPECIFICATION forming part of Letters Patent No. 699,306, dated May 6, 1902.

Application filed J'nne 1'7, 1901.

To all whom, it may concern:

Be it known that I, HENRY GOLDENFARB, a subject of the King of England, residing at 36 Oamomile street, London, England, have inventedlmprovementsin SafetyAppliancesfor Use in Cleaning IVindows from the Outside, (for which I have made application for Letters Patentin Great Britain,No. 21,012, dated the 21st of November, 1900,) of which the following is a specification.

This invention relates to an improved safety appliance for use in cleaning windows from the outside.

According to this invention the appliance consists of two lengths of wood or other suitable material so attached together that they may be drawn out longitudinally. To the outer end of each length I attach a bolt or stud with an adjustable screw-nut, which I prefer to make round. I provide a number of holes through which pins or screws may be passed to hold the apparatus rigid when extended to any required length. I also provide a ring, pin, or other suitable fastening at one end of the appliance for the purpose hereinafter described, and in order that my said invention may be clearly understood I will'describe the same with reference to the drawings accompanying this specification, in which Figure 1 is an elevation showing the appliance clamped across a window as when in use. The scale to which this figure is drawn is larger than that of the others. Fig. 2 is a side view of the appliance. Fig. 3 shows the front of the appliance. Fig. 4 shows back of same. Fig. 5 shows the belt worn by the cleaner.

The same letters of reference denote the same parts in all the views.

a and b are two lengths of wood. The piece a has fixed to it a hasp c, which slides over the piece Z), and the piece I) has a similar hasp cl, sliding over the piece ct.

e is a ring on the hasp c, and fis a pulley carried by the hasp cl.

g is a cord fastened to the ring a and passing over the pulley f.

The length of wood I) is provided with holes 7t and the length a with a few holes i at gradually-lessening distances apart.

Serial No. 64,917. (No model.)

]l; is a pin.

m m are screws screwing through the heads at of the pieces a and I). These screws m are provided with heads or nuts 0.

p is a stout rope held securely by a pin q and. having at its other end a loop or eye 7'.

The belt shown at Fig. 5 has attached toit a hook or catch .9.

The appliance is used by engaging two diagonally opposite corners of the inside beading of the window between the nuts 0 and the wooden heads 'n. To do this, it is necessary to raise the bottom sash, adjust the screws m to the width of the beading, open out the appliance to the correct length by pulling on the free end of the cord g, and to lock it at such length by passing the pin 70 through the two holes, which coincide, in the pieces ct and b. The window-cleaner wears the belt shown at Fig. 5 and attaches the hook s to the loop 1 of the rope p, which is outside the window. Thus should he slip he is prevented from falling.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In an apparatus of the character de scribed, the combination with a bar, a clamping-screw on one end of said bar, of a second bar having a clamping-screw on one end and adapted to slide on the first bar, a guide-clip on each bar through which the other bar is adapted to slide, and means for locking said bars together, substantially as described.

2. In an apparatus of the character described, the combination with a bar, a clamping-screw on one end of said bar; of a second bar having a clamping-screw on one end and adapted to slide on the first bar, a guide-clip on each bar through which the other bar is adapted to slide, means for locking said bars together, a rope attached to one of said bars, a belt, and means for attaching said belt to said rope, substantially as described.

3. In an apparatus of the character described, the combination with a bar, a clamping-screw on oneend of said bar; of a second bar having a clamping-screw on one end and adapted to slide on the first bar, aguide-clip on each bar through which the other bar is adapted to slide, a pulley on one of said clips, a rope attached to the other clip and passing ing-screw on one endof said bar; of a second over said pulley for sliding one bar on the l over said pulley fol-sliding one bar on the other, and means for locking said bars to- 1 other, means for locking said bars together, gether, substantially as described. a belt, and means for attaching said belt to 4.
