* UNITED STATES JOHN H. COOK, 0F SALT LAKE CITY, UTAH.

wmnow SCAFFOLD.

Application filed. April 11, 1923. Serial No. 631,450.

To all whom it may concern:

Be it known that I, J OHN H. COOK, a citizen of the United States,residing at Salt Lake City, in the countyof Salt Lake and State of Utah, have invented certain new and useful Improvements in lVindow scaffolds, of which the following is a specification.

The present invention relates to means for supporting a person with safety outside a window or other opening in a wall, and the object is to provide a. structure of a novel and simple character that-can be compactly folded, so that it will occupy but little space when not in use, and when extended and placed in use, will constitute a practical and safe support. The device moreover is readily adjustable to different sized openings.

In the accompanying drawing Figure 1 is a plan view of the preferred en'ibodiment of the invention.

Figure 2 is a view in elevation of the same.

Figure 3 is a detail view in side elevationof one of the holding brackets.

Figure 4 is a detail sectional view on the line 1l of Figure 1. p

In the embodiment disclosed a guard railing is employed, comprising a pair of-sections 5 preferably in the form of an open framework and hingedly connected as shown at 6, so that they may be swung to different angular relations or brought close together; The lower front corners, of the sections 5 may have bearing knobs 5. sections is provided at its lower edge. with a horizontal supporting bracket 7. The two sections are adapted to be held in angular relation by means of an extensible bar or rod, comprising telescoping sections 8 and 9, the section 8 being journaled, as shown at 10, upon the bracket 7, and the section 9 having a terminal hook 11 adapted to engage in an eye 12 on the free end of the opposite rail section to that carrying the bracket 7. The telescoping rod sections 8 and 9 are held in adjusted relation by a pin 13 passed there One of these the sections 5 as shown atl'? are horizontally swinging bracket elements 17 having projecting socket extensions 18 at their lower ends which extensions are also j ournaled on the front vertical bars of the sections 5, as shown at 18; In'the sockets of said extensions are slidably mounted the shanks 19 of cushioned hooks 20 that are adapted to engage the inner sides of the window-frame. The shanks 19 are provided with a plurality of openings 21 throughwhich can be passed securing pins 22. Interposed between the extensions 18 is a spreader consisting of a tubular section 23 journaled, as shown at 24, on one of the extensions 18, so that it may be swung in a vertical plane. The other extension has pivotally and slidably connected thereto, as shown at 25, a' rod section 26 that can be swung in a horizontal plane.

The rod section is adapted totelescope into the tubular section and is held in different positions by a pin 27 adapted to engage in any of a series of openingscin the rod or in other words, corresponds to the detail struc: ture shown in Figure 4. If the parts 19 are swung outwardly or away from each other, the rod section 26'will disengage from the tubular section 23 and may be folded in wardly alongside the adjacent part 18 while the tubular section can be swung upwardly parallel to the adjacent part 17, as a preliminary to folding the scaffold. It will be evident that this structure when not in use can be compactly folded, so that it will occupy but little space, and can be conveniently carried. .On the other hand, it can be quickly setup and placed outside a window, soas to constitute a safe and con.- venient scaffold, the parts being readily adjustable in order that it may be made effective, irrespective of the size of the openings in which it is placed.

From the foregoing, it isthought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled .in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. 7

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A window scafiold comprising a guard rail composed of sections pivoted together on an upright axis, devices carried by the free. portions of the guard rail sections for supporting engagement with the walls of an opening, means for holding the sections and devices spaced apart to maintain such supporting engagement, and a platform that is supported between and bythe rail sections.

2. A window scailold comprising a guard rail composed of sections pivoted together on an upright axis, devices carried by the free portions of the guardrail sections for supporting engagement with the walls of an opening, an extensible spreader between the free ends of the guard rail sections, a. platform that rests upon the spreader and the lower portions otthe rail sections, and wall-engaging hooks adjustably mounted on the free portions of the rail sections.

3. A window scaffold comprising a guard rail consisting of a pair oii sections hinged together at their adjacent ends and adapted to be placed in angular relation,- a substantially triangular platform that fits between the sections and has portions that rest thereupon, and means pivotally mounted on, the free ends of the rail sections for mounting the scaffold at an opening in a wall.

iii-1th window scaffold comprising a guard rail consisting of a pair of sections hinged together at their ad acent ends and adapted to be placed in angular relation, a substantially triangular platformthat fits between the sections and has portions that rest thereupon, certain of said port-ions passing throughthe railing.

5. A window scaffold comprising a guard rail composed of sections pivoted together on an upright axis, devices carried by the free portions of the guard railsections for supportlng engagement with the walls of an opening, an extensible spreader between *mounted on the holding device and the free ends of the guard rail sections, a platform that rests upon the spreader and the lower portions of the rail sections, wallengaging hooks pivotally mounted on the hinged together at their upright meeting edges, an extensible spreader between the free ends of the guard rail sections, hooks pivoted on said free ends, and an extensible spreader connecting the hooks.

8. .A window scafi'old comprising hingedly connected railing sections, a holding device between the same, and a platform movably adapted sections angular to be placed between the railing when said sections are disposed in relation. Q I

9. A window scafi'oldvcomprising railing sections hinged together, a holding bar de-- tachably connecting the free portions oi the sections to maintain them in angular rela tion, and a platform journaled on. the bar and adapted to swing to a position between the lower portions of the railing sections and rest thereupon. g

In testimony whereof, I affix my signature in the presence oftwo witnesses.
