SPECIFICATION forming part of Letters Patent No. 718,602, dated January 20, 1903.

Application filed May 31, 1902. Serial No. 109,638. (No model.)

To all whom it may concern: In the present embodiment of my inven- Beitknown thatI,JAMEsL.CHAsE,a citizen tion the base is shown as an elongated flat of the United States, residing at-Ayer, in the bar B,conveniently made of wood and adapted county of Middlesex and State of Massachuwhen in use to rest fiat upon the roof or other setts, haveinvented an Improvementin Roofinclined plane R, Fig. 1, and a metallic hook- 55 Brackets, of which the following description, like ridge-holder B is rigidly secured to the in connection with the accompanying drawupper end of the base.

Fig. 2 is made in the platform-support near one end, is a lower end view, enlarged, of the base, Figs. 1 and 3, and such end may be protected showing the cross sectional shape thereof and strengthened by a metal strap 10, if deand the lower slide thereon with the lower sired. Along the metal-shod portion of the 45 end of the brace connected with the slide; platform-support aseries of transverse holes and. Fig. 3 is an enlarged detail, in side elep are made extending from one to the other vation, of the upper end of the base and the side for a purpose to be described.

shown at the upper part of Fig. 1 and in Fig. 3, so that the platform can be erected right across the ridge, if desired, the slide C then being at its highest point on the base and held from downward movement by a stop-pin inserted in the uppermost hole Z) in the base. Similarly a stop-pin (Z retains the slide D from downward movement on the base. (See Fig. 1.)

When the platform is to be erected below the ridge, the slide 0 is held by it stop-pin at the desired height, as shown at the lower part of Fig. l, and the connecting-pin 12 is then passed through the end hole 13 of the platform-support P and through either of the holes 0 c in the ears c The metal-shod portion of the platformsupport has mounted upon it a slide P having depending parallel ears 19 which extend below the platform-support and are provided with holes near their lower ends and also with holes adapted to register with the opposite ends of one of the holes 12 to receive a locking-pin p which locks the slide P at any desired place on the platform-support.

A rigid bar H, constituting a brace, has its upper end inserted between the ears of the slide P and is pivotally connected therewith by a pin p extended through the lower set of holes in the ears 19 The pin d is passed through a transverse hole in the lower end of the brace inserted between the upturned ears (I of the slide D, and the brace is connected pivotally at its opposite ends with the slides P and D, respectively.

Manifestly the platform-support must be maintained in substantially horizontal position, and when its inner end has been set at the desired height by adjustment of the slide 0 the slides D and P are moved until the brace is substantially vertical and the platform-support 1 horizontal. The slide P is then locked in place, and by means of the stop-pin (Z the slide D is held from downward movement along the base, the brace and platform-support being thus held from movement relatively to each otherand to the base while still connected by slidable and pivotal couplings or connections. If desired, the ends of the brace may be strengthened by metal straps 71.

For the purpose of most clearlyillustrating my invention I have shown a pair of roofbrackets in Fig. 1 and with the platform-supports P arranged slightly above the ridge in the upper part of the said figure, while the lower part shows the platform-supports arranged for work at a lower level.

While one base member may be utilized to sustain two platform supports and their braces at one time, I prefer to have only one platform-support and brace for each base and to adjust as may be necessary.

It will be obvious that the planking for the platform will be laid upon the platform-supports P, affording a strong stable staging for the workmen.

When in use, the lower ends of the bases of a pair of brackets are connected by a link M, having its ends hooked into eyes 12 on the bases, and a rod N is extended through the outermost hole p of each platform-support and clamped to the latter by set-bolts p in the ends of the support-s. The bracket-base rests firmly on the roof, and the weight which the platform may have to support is distributed over a very considerable area of the roof. The brace is subjected to compression by the weight on the platform, and the greater the weight the more firmly will the bracket be held thereby on the roof.

From the foregoing description and the drawings it will be manifest that repairs to a chimney or roof can be made with equal faeility whatever the roof pitch, the location of the chimney relative to the ridge of the roof, and the part of the latter at which repairs are to bemade. It will also be manifest that the bracket can be used for wallwork by hooking the holder B over awindow-sill, 850., and suspending the base, the brace and platform-support being adjusted with the latter in horizontal position.

If desired, the stop-pins 0 d 'may be attached to the platform support and brace, respectively, by a chain or other flexible connection, as in Fig. 1; but if so a separate pin mustbe used to hold the slide 0 in place when the platform-support is positioned as shown in Fig. 3 and the upper part of Fig. 1.

The connecting-pin 12 is preferably made with a head at one end and a threaded opposite end to receive a suitable thumb-nut 18, preventing accidental withdrawal of the pin.

My invention is not restricted to the precise construction herein shown and described, as the same may be modified or changed in various details by those skilled in the art without departing from the spirit and scope of my invention.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. A roof-bracket comprising an elongated base, a hook-like rid ge-holder connected therewith, a platform-support slidably connected at one end with the base, a brace, sliding couplings between one end thereof and the platform-support and sliding couplings between the other end thereof and base, and separate means to prevent movement of the platformsupport and brace relatively to each other and to the base when in adjusted position.
