An embodiment of the invention is shown in the accompanying drawings, in which latter,- i

F ig. 1 shows a portion of a shingled roof in vertical section, and a roofing bracket including the said embodiment ofthe in vention,

Fig. 2 is a view-showing in verticalsection on a scale larger than that of Fig. 1 certain of the parts of Fig. 1, namely the roofing bracket and the retaining strip therefor, without the scaffold boards which in Fig. l are shown resting on the horizontal memb of the said bracket. I

Fig. 3 is view in side elevation of the folded-up bracket, andFig. 4 is a view thereof in plan, both on a still larger scale."

Fig. 5 is a view showing on a larger scale than 4 the retaining strip and thev upper cnd of the bracket, andillustii'ating the onnection' between said strip and the basemem Jer of the bracket.

Fig, 6 is a view showingon a still larger scale, in cross-section on

line

Fig. 1 presents a'conventional showing of slates, or conceivably

shingles

1, 1, overlying

roofing boards

2, 2, supported by inclined timbers 3, 3, of a roof. The bracket which is shown applied to the roof in Fig. 1 andshown separately in Fig. 2 comprises (1) the base-member l, which in the use of the bracket lies upon the inclinedexposed surfaces of the slates or shingles which already have been applied and attached to the roof, (2) the member 5'which in the use of the device occupies a. horizontal or substantially horizontal position as 1, suitable for supportingthe boards. 6 of a platform or staging, and the strutanemher 7, which in the use of the device 00- cupies an upright or substantially upright position, supporting the board-supporting member 5 in the said horizontal or substantially horizontal position.

The bracket shown in thedrawings is of folding construction, in order that when not use it may be folded up into small compass for convenience in carying it about from place to place, and in storing it. The capacity for folding and unfolding is provided for by means of a hinge-connection, as at 8, Figs, 1 to 4, of one end of the PATENT OFFICE.

board-supporting member 5 with that endportion ofthe base-member 4 which, while the bracket is in place upon, a roof, is the upper or more elevated end of said basemember; further, by -.means of a' hinge-conof the board-supporting member 5and one end of strut-member 7 and further by making the engagement of the other end of the strut-meinber '7 "with the base-member, for

vnection, at 10, between the opposite endholding the parts in working relation with:

respect to one another as in Figs. 1 and 2, a detachable one i One portion of the invention resides in a special construction and interrelationship of the

elements

4,, 5, 7 composing the folding bracket.

In accordance with the invention I employ as a base-member 4: a strip of sheet-metal having the opposite longitudinal marginal portions-thereof bent at right angles to the intermediate portion so that they constitute

parallel sideflanges

41, 41,. which extend from that end ofv the base-member which in the use of the bracket is relatively depressed to a short distance from the opposite end, giving the base-member-for the greater portion of its length the shape of a channel-iron and thereby securing stiffness and strength while enablingthe-said memher to be made quite light, TlldGIlCl-POrtion extending beyond the upturned side- 'flangcs is flat, as shown, to permit it to be overlaid by slates or shingles of a course applied to the roof above the main portions of the bracket. The board-supporting member 5 composed of two flat strips, parallel with each other as ind'cated in Figs. 4. and 5.and which are located at the inner sides of the side-flanges of the base-member. The

hinge-connection between one end of the hoard supporting member 5 and the basemember is constituted in this instanceby a rivet or bolt 8 occupying holes in the side- -flanges41, 41,'and in the corresponding Ion ends of the said flat strips. A'spa'cing sleeve 9, Figs. 2 and 4, is applied to the stem of the said rivet or bolt between the two strips to hold them apart and also hold them close to the said side-flanges. At the opposite end of board-supporting member 5 the corresponding end-portions of the two strips receive between them that end-portion of the strut-member 7 which is in hingeconnection "with said member 5, such hingeconnection being established by means of a Ill) her. to suit the var rive bolt 10, The said end-portion of stiutniember 7 extends sufliciently beyond the g aoint of hinge-connection to enable such end-portion, when the parts are relatively positioned as in Figs. 1 and 2, to project above the board-supporting member 5 like a short post, far enough to constitute a stop to prevent boards 6' resting on member 5 as in Fig, 1, from falling or being knocked off from the said member, Thestrut-mernber 7 is composed of sheet-metal, bent into the shape of a channel-iron, with the

strips

5, 5, applied tothe outer surfaces of its parallel side-flanges, and with the hinging-rivet or bolt 10 occupying holes in the said flanges and in the strips In setting-up the bracket for use on a roof the board-suppoiting member 5 is adjusted in the required position relative to the basemember 4 and held in such relative position through engagement of the lower end of the strut-member 7 with one of a plurality of stops 42, 49., with which the base-member is provided between the side-

flanges

41, 41, of the b se-n'iember. Thereis a series of these stops, the individual stops being respectively located at different points in the length of the base-member, in order that the strut-member may be engaged with one or another of them, as may be required in order to give the board-supporting member 5 the angular relationship with respect to the base member which is required for supporting the said member and the boards 6 thereon in horizontal position. This adjustment will vary according to thepitch of the roof on. which work is to be done. The stops in this instance are constituted by substantially L-shaped pieces which are bolted to the bottom of base-member 4, with one portion of each standing up from the said bottom. Engagement of the strut with the, predetermincd stop is effected by placing the lower end of the strut at the inner or upper side of the upstanding portion of such stop. To provide against accidental disconnection of the strut-member from g the stop with which it is associated for the time being,

headed

studs

421, 421, are provided on the inner sides of the stops, and the lower end of the stint-member is formed with a keyhole-shaped slot, 72, Fig. 6, toreceive the stud of the stop to which the said. end is applied in the use of the bracket. See Fig. 6. The upstanding portions of the respective stops are inclined atdiiferent angles with respect to the bottom of the base l ions in the ineli 'of nails driven into the roof boards.

shingling.

formed with three

holes

43, 43, 43, lfig. 4, 4

which are adapted to receivethe head ends The

holes

43, 43, 43, are keyhole-shaped, the

large portions of the said holes being adaptedto permit the heads of the nails to passtherethrough, and the narrow portions or necks being adapted to engage with the stems of the'nails beneath the heads thereof. This means of holding the'bracket in place will be utilized whenthe bracket is employed in connection with the work of When it is desired to remove the bracket after-the performance of the shingling operations, the bracket may be dis-- engaged from the holding nails by sliding it upward so as to bring the enlarged portion of the

holes

43, 43, 43, into position to accommodate the nail-heads, and then lifting the bracket off the nail-heads. The

shingles overlying the fiat end-portion of the bracket will spring sufficiently to enable the bracket to be lifted to an extent suflieient to efiect the disengagement. The bracket may then be pulled down from'the nail-heads and out from under the overlying {shingleends.

Figs. 1,2 and 5 show combined with the .bracketa plate 15 such as heretofore has been employed in practice with roofing brackets in performing the work of attach ing slates to a roof. For use, this plateis engaged at its lower endwith the flat upper end-portion of the base-member 4 by means of two headed

stuts

151, 151,an'd a belt 153 and thumbenut 154 which are shown best in Fig. 5. In effecting the engagement the said headed studs are caused to occupy the two laterally-located Keyhole-shaped holes .43, 43, with the neeks of the studs in the narrow portions of said holes. In this relation of the parts avhole in the plate 15 registers with the intermediately located I hole 43,,and the bolt 158 is-insertedinto the registering holes, after which the nut, 154 is applied. and tightened. Thenpper end of the plate 15 is formedwithhooks 155, 155, for engagement with nails 156, Fig. 1,

' to me roofboards and left w th ghtly projeeting,these nails l at coo; enien points eoove the ie laces of course already courses and the nails 156 will be driven with in the upper ends of the oblique slots forming the hooks. The subsequent removal of the bracket from under courses of slate of the slots forming the hooks slide against the nail stems and therebydefiect the upper end of the plate sidewise suiiiciently to bring the straight slots at the side of the hooks, constituting the openings of the latter, into position to receive the nail stems, which will permit the plate to be drawn downward along the roof clear of the nail stems. The use of the plate 15 in laying slate is made necessary by the fact that the slates would break if it should be attempted to spring or bend them upward for the disengagement of the bracket as in the case of shingles. Consequently, a plate which will. extend above the upper ends of the last course of slates sufficiently far for engagement with nails driven into the roof'boards is necessitated.

Accidental disengagement of the lower end of the plate 15 from the upper end of the base-member 1 of the bracket is provided against by so locating the holes for the bolt 153 in the lower end of the plate and in the flat portion of the base-member 4 that such holes do not register until the stems of the headed

studs

151, 151, on the plate have been drawn up into the small portions of the keyhole slots 48, 43, in the flat portion of the base-member. After the bolt 153 has been passed through the registering holes, and the nut 154 has been applied and tightened up, movement of the plate endwise with reference to the base-member is impossible and accidental disengagement is guarded against. 7
