CHIMNEY-SCAFFOLD BRACKET Application filed December- 10, 1923. Serial No. 325,025.

My present invention has reference to an adjustable staging or scaffolding for pitch or gable roofs supporting The primary-object of the provision of extremely simple but strong and durable brackets which may be arranged and sustained upon a roof without the employment of nails or analogous devices, and which will effectively support thereonthe scaffold boards for the masons and material employed in building or repairing chimneys.

A further object is the provision of a device for this purpose which while strong and durable shall be light in construction and which may be readily folded to provide a small package that can be conveniently carried from building to building or stored in a small space when not required for use.

A still further object is to provide a scaffold bracket for pitch roots which sh all comprise two members designed each torest and to be supported on the opposite sides of a pitch root, easily and qulckly adjustable with brackets for such scafioldings.

respect to the roof, and readily separable.

brackets, or rather one whereby one of the be employed independpair of brackets may ently of the other.

The invention will be fully and comprehensively understood from a consideration of the following detailed descriptionwhen read in connection with the accompanying drawings which form part of the application, with the understanding, however, that the improvement is capable of extended application and is not confined to the exact showing of the drawings nor to the precise construction described and, therefore, such changes and modifications may be made therefrom as do not affect the spirit of the invention nor exceed thescope thereof as expressed in the appended claims.

Figure 1" is a side elevation of the device when in folded condition.

In the showing of the drawings my improved scailold brackets are illustrated as arranged in connected pairs upon the angle sides of the roof of a building 1. It will be apparent, however, as the description progresses that a single pair of these brackets upon one of the angle sides of the roof may be employed.

Each bracket constitutes a rootengaging member in the nature of a board or plate 2. On its under face each of the plates 2 has fixed thereto transversely arranged metal stripswhich I will term cleats and which are designated by the numeral 3 in the drawings. The cleats 3 are arranged respectively at the center and at the ends of the plate 2 andproject beyond the edges of the said plate. The projecting ends of the cleats have openings 4 therethrough for the reception of nails or like securing elements when it is necessary to nail the plates 2 on the root. In this connection it should be stated that when the device is arranged as illustrated by the drawings nonails or other securing elements are required and that the cleats 3 serve as frictionmeans upwardly outwardly directed flat eye portions 8. The eyes receive therethrough removable pivots 9. The pivots 9 pass through the depending arms 10ofsubstantially U-shaped members which underly and provide rests for the plates 11. Resting on the plates l l are, the confronting ends of the scaffold supporting plates orfboards12, and

disposed over the confronting ends of the said scaffold,boardsjthere are longitudinal x plates 13 disposed opposite the plates 11.

notches 18. The plates 17 have passed there Passing throughthe plates 13, the scaffold supporting boardsor members 12, through the plates 11 and the U-shaped members, which carry the arms 10 there which are engaged bynuts.

Arranged between th'eupstan ding elements 5 on the plates 2 there are the rack members .16 of the improvement. Preferably'each oi. "the racks comprisesabcardthat hassecured to its edges metal plates 17, and these plates have their'inneredges provided with alining through removable pivots 19 that also pass through the openings 6 in the elements 5. Securedon the edges of the scattold or staging supporting members 12 and extending beis substantially U-shaped, as disclosed by Fig ure 5 of the drawings, and the said body is v centrally formed with a stem 26 which is threaded. By swinging'the levers to bring their cam faces 23 against the notched members or cracks 16 the latter will be swung toward the members 12 so that the rods 21 will be received in one pair of the notches 18 in the said members .16. 7

Received in one pair of notches in each of the members 16there is a continuousmember oryoke provided at its outer end with an eye 28 through which the stem 26 passes, and

there is threaded on the stem 26 for adj ustabie contact with the eye 28 a bolt 29. lhe staging j boa'rds supported upon the members 12 are indicated by the numeral 30. The members 12 are preferably of wood and .ifnecessary 'thestaging boards30 may benailed thereto. Under ordinary weatherlconditions, however,

j this is not necessary.

From the fOI'BgOIDgClGSCIIPUOH when read in connection with the drawings it will be "seen that I have produced a simply constructed, cheap, evenly balanced but ehicient bracket ior supporting scafiold ngor like stagmgs which'may be'easily arranged on the roof,

' 'readilyadjusted with respect to said roof and which is of a strength to supportthreon the are .bolts 14 masons and the material required by the masons in erecting or repairing a chimney in the building 1.

As previously stated, one pair of brackets instead of two pairs of connected brackets may be employed when the device is not to be used on the peak 01 the roof. In this instance, it is merely necessary to remove the nuts from certain of the bolts 14, and thus detach one member 12 from the other member 12. /Vhenone pair of thebrackets are employed it will be necessary to drive nailsor other securing elements through the open ings 4 1n the cleats 3. When the device 1s not required'for use the nut 29 is unscrewed from the shank 26 of the cam levers 24c, permitting the yokes 27 to wing on the members 16, and likewise permitting the nembers 16 being brought out of engagement with the cam levers and with the rods 21 and thereafter swing over the plates 2 in a direction toward each other, as disclosed by Figure 11 of the drawings. By reference to this figure it will be seen that the device when folded or collapsed producesa small bundle which may be readily conveyed from one building to another and stored into a small space when the device is not in use. Having described the invention, I claim 1. A scaffold bracket for pitch roofs, comprising a-plate to be laid on a roof, cleats arranged transversely on the under face of the plate and extending beyond the edges thereof and havingopenings, securing means to pass through the openings that enter the roof, a staging supporting memberhingedly securedto the plate and having outer extensions, and a transverse rod connecting said extensions, a notched member pivotally secured to the plate and received between the mentioned extensions, a cam lever pivoted between the extensions and swingable to contact with the notched member to move the same to bring the rod into one of the notches on the notched member. l

2. In a foldable scafiold bracket, roof engaging. plates having cleats, arms pivoted to one end of the plates, right angular elements fixed on the ends of the arms, scafloldsupporting members removably secured to said elements, plates secured to and extending beyond the outer ends of said members, a lever having cam ends which are pivoted to said last named plates, notched members pivotalthereof, and means for locking the cam lever -ly secured to the roof plates, swingable to yokes for holding said yokes on
