As is well known, most roof surfaces generally are pitched to such a degre that workmen who rhust'move about thereon for a variety of reasons "must be continue ouslyalerttto the danger of slipping and falling During a shingling operation.when'bundies of shin l a "ther materials must behandled, the difficulty of, footing on a roof surface is, Of Course, greatly incr While various crude supportsjofianfim'p manen have been constructed by work-meno them move abouton aroof with gre no one'has to my knowledge desig in; the advantages to be outlined.

A further object of my invention is to design n ud sagenerallv u hap' nk 6." ing strap 17' with'on'e sidewa l l ned inwa a ,7 H a e;- m e ype p n pp r n 'br c etsuitablefq' Another. object of the invention'is to, tit T51 or brackets which can be very easily and simply sec" ed to a roof and thence'as easily removedthere-froin for se 1*;- on another roof. f L A further ct of the n ention i to arovidea raqki et of light weight construction which islj'extreelyj V and rugged in design and in, nofniannfil, i a shingling operation. Another object of the inventionis to desigp a bracket which once locked in position cannot "slip ester adjustment to tip the plank which it-suppoltts. and-endanger the men and materials thereon.

A further object of the invention t o be m ed n w d vbf a a to he and, the edgietlla (see Fig; 3)," n'g n't il L' qn't e ild l ql l n w t n fi i f hen 1 2 i emiivt d n h ooneofthe recesses 12 the wing nut 23 ma which very reliably su per: a plank 5 e: ner so that'itcann'ot slip from thbracketsi se'gineiit Another object of the invention is to provide a bracket Provided in the front end of base plate 10 are a pair of the character described which is designed so that its of keyhole slots 24 which permit the bracket to be adjustment to correspond with the pitch of the particular readily nailed on the roof at 24a and thence disengaged roof on which it is being used is a very easy matter and therefrom in the usual manner, the heads of the nails requires no tools of any kind or any disassembly of parts. 24a being, of course, of greater diameter than the re- A still further object of the invention is to design a duced portions of the slots and of lesser diameter than the bracket which can be very economically manufactured enlarged portions of the slots. and sold at a relatively low price on a quantity produc- In practice the shingling operation proceeds from the tion scale. lower side edge 25 of the roof R (see Fig. 1) toward With the above and other objects in view, the present the ridge thereof and after several courses have been invention consists in the combination and arrangement secured in place two or more of the brackets B which of parts hereinafter more fully described, illustrated in I have described may be nailed to the roof, preferably the accompanying drawing, and more particularly pointinto the rafters supporting the roof surface. The brackets ed out in the appended claims, it being understood that B may then be adjusted until the plank supporting straps equivalent changes may be made in the various elements 17 are horizontal regardless of the pitch of the particular which comprise the invention without departing from roof being shingled. If the wing nut 23 is loosened the the spirit thereof or the scope of the appended claims. pin or bolt 22 may he slipped outwardly in the slots In the drawings: 7 21 to the position in which I have shown it in Fig. 3. 'Fig. 1 is a fragmentary plan view of a partly shingled The member 14 is then free to pivot on pin 16 and when the strap 17 is horizontal the bolt may be slipped into the adjacent recess or notch 12and the wing nut 23 may be tightened down. Since the slot 21 is disposed at an 1 angle relative to thenotches 12 and restricts the mouth of, andtch 12 edans bolt 22 cannot pass out (see- Fig. ,2) the bolt 22 will not slip. out of any of the notches 12 when a weight restsori the member whether nut 23 is fully tightened down.

Thebrackets B in Fig. l are, of course, positionedjin lateral alignmentfand it is a very simple matterf'to slip a plank under the flanges 18 of the straps 17 so that it re a d Pi;

is securely held therein. The weight supported oiithe' plank P is not entirely borne by the bolts '22 but rather is borne jointly by the bolts 22 and pins 16 andj'these membersare, ofcourse, of siiflicient strength so as to becapable of bearing many times the maximum weight whichmight be applied. The bolts 22 restrain thememing edge with circumferentially spaced notches therein defining a plurality of vertically spaced teeth; a plank supporting member hinged to said base plate intermediate its ends having a dependent section with a wall generally parallel to and alongside said segment; said wall having an elongated slot disposed to generally register with said notches when the plank supporting attachment 1 is pivoted and said section swings said slot in an are past said notches, with the slot having also an outer portion outward of said notches when the slot is registering therewith; clamping means extending transversely through said slot, in one position in said slot being accommodatable by oneof 'said notches, and in another position being outward of the notches so thatitis free thereof to permit here 14 from pivoting about the pins 16 andtra'nsfer theweight applied directly to the rear end of the plates 10 and roof, If for some reason the bolt 22 should shear,the member .14 could not'tip very far since the flat upper edge 11b of the segment 11 would be engaged by the under-surface of strap 17.

Since the front ends of thebase plates 10 project forwardly they may be nailedinto the unshingled section oftheroof justahead of the last course shingled and the next'cou'rsemay then lap over the front ends of the brackets as does the shingle 26 in Fig. 1.' To, release the brackets it will only be necessary to push them forwardly or upwardly until the nail heads securing them are out of the reduced portions of the keyhole, slots 24 whencethe brackets may simplybe lifted up and withdrawn from under the shingles 26. Clearly in view of the design of the brackets itwill not be necessary to nail the rear ends of the bases 10 to the roof.

, It shouldflbe apparent that I have perfected a very practical bracket which can be used for other purposes adjustment of said section in an arc to register the slot with another notch; the slot being angularly disposed relative to the notches so that its top marginal edge restricts the mouth of the notch in which the securing means is disposed and prevents the clamping means from movingoutofthe said latter notch and the said section from pivoting downwardly even though the clamping ineans be relatively loose 2. A shingling bracket forsup'porting a portion of a scaffold plank in horizontal disposition above a pitched roof surface comprising; a, base adapted to be secured on said surface with its front end upward; a vertical wall on said base; a plank supporting member hinged to said base intermediate its ends having a dependent section with a plate generally parallel to and alongside said wall; one of said wall and plate having a curved freeed'ge with circumferentially spaced notches therein defining a plurality of vertically spaced teeth; the other of said 'wall and platerhaving an elongated slot disposed than shingling'wherever it is necessary to support a weight on a pitchedsurface. Obviously, however, the bracket which incidentally is preferably of all metal construction is"par ticularlyj adapted to roofing operations and will findwideusein this field. j

It isto'be understood that the drawings and descriptive mattergare in all cases to be interpreted as merely ilhis? trative of the principles of the invention rather than as limiting the same in any way since itis contemplated that various changes may be made in the various eleto generally "register with said notches when the plank supportingattachment is pivoted and said slot and notches have relative movement; with the slot having also an outer portion outward of [said notches when the slot is registering therewith; clamping means extending transversely through said'slot, in one position in said slot being accommodatable by one of said notches, and in anotherposition being outward of the notches sothat it is free thereof to permit adjustment of said section in an arc to, register the slot and another notch; the slot mentsto achieve like results without departing from the i spirit of the invention or the scopeof the appended "lclaimz N .1. A shingling bracket for supporting a portion of a scafiold plank in horizontal disposition above a pitched iroof surface comprising; a base plate adapted to be secured on said surface with its front end upward; a vertical segment on said platehaving a curved rearward facbeing angularly disposed relative to the notches sothat its top marginal edge restricts the mouth of the notch in which thesecuring means is disposed and prevents the clamping means from moving out of the said latter notch and the said section 'from pivoting downwardly even though theclamping' means be relatively loose.
