ROOF BRACKET 0R JACK v Filed Nov. 26, 1930 Wma APaienteci July 1933 LOUIS P, -BEIMANN, OF BUFFALO, NEW YORK ROOF BRACKET OR JACK Application filed November 26, 1930. Serial No. 498,328.

My invent-ion relates to improvements in a roof scaffold bracket or jack; and it has for one of its objects the provision of a bracket or jack adapted particularly for usey when shingling or otherwise covering roofs, or

when repairing old roofs.

Another object of my invention is the provision of a bracket or jack of the kind mentioned, which is durable, simple in construction, adjustable to roofs of various pitches 'or' inclinations, and one ywhich can be easilyl applied and as readily removed Vwithout damaging any portion of a new roof alreadyv completed, or any serviceable shingle or other covering units of an old roof, when making repairs to such roof.

1ilith the above and other objects in view to appear hereinafter, the invention consists in certain novel features of construction, and in the combination and arrangement of parts to be hereinafter described and more particularly pointed out in the subjoi'ned claims.

ln the drawing:

Fig. 1 is a perspective view of the upper portion of a building in the course of con* struction, showing the same partly covered with shingles andthe manner of attaching my improved bracket or ack thereto, with a 3 view of cooperation with al similar bracket or `iack spaced at a distant pointalong the roof,

so as to enable a suitable plank or support tov be placed upon both brackets or acks with a view of serving as a walk'to carry the weight h35j of Workmen applying shingles or other covering units to the roof, or repairing such on an old structure. Y

Fig. 2 is a vertical section through a roof and through my improved bracket or ack,

Reference being had to the drawing in detail, the numeral 9 designates the roof boards 60- of a roof forming the foundation for the shinf gies 10, or other covering units of the roof. Y

- Covering units of various kinds are commonly employed on roofs; some being of wood, others of slate, and still others of asbestos and other compositions, and these are invariably laid in horizontal rows on the foundation of the roof in overlapping arrangement.

In the drawing I have shown the usual elongated wooden shingles which are laid in horizontal rows or courses, and my improved bracket or jack is adapted to be applied to the uppermost layer or course of shingles conveniently reached by the workmen from a lower position during the operation of applying the shingles or other covering to the roof. For this purpose a plurality of nails 11 are driven into a shingle of the uppermost course Alaid so that the headed ends ,of the 8C nails extend a. trifle above the outer surface of the shingle, and my improved bracket or jack is hung on said nails in the manner to presently appear. lVhen brackets or jacks so applied are opened, as shown in Figs. 1 and 85 '2, a plank is laid thereon and serves as a support for the workmen. Additional layers or courses of shingles can then be applied to the roof formation, the iirst and possibly` the sec-v ond additional layer or course being placed over the upper ends of the brackets, as best shown in Fig. 1.

Eachbracket or jack comprises a comparatively thin supporting member 12 formed of a narrow strip of sheet metal curved upon- 95. itself, as at 13, to form an eye, and provided between its ends at opposite edges thereof with upstanding lugs 14, whichare formed by cutting into the supporting member from Y the edges thereof and bending the material P00 pwardly or at right angles to the face of said member; these lugs being provided with transversely alined holes 15.

Near the other end of the supporting member alongone edge thereof, spaced oblique ydisposed notches lo' are formed; these notches terminating in laterally-odset rounded extensions 17 into which the nails il adapted to be entered, or said nails may be driven through the notches at said odset extensions;

thus holding the supportingl member' in placa on the root.

Pivotally connected to the eye 13 of the supporting member is the lift or jack member 18. This member is also constructed or sheet metal bent into channel formation to provide opposite vflanges 19, and through the lower or inner ends of these flanges, pivot openings 20 are formed. rlhese pivot openings are in registration with the opening through the eye 13 oi the supporting member, and a pivot pin 21 is passed through said eye and said openings 20, thuspivotally connecting the litt or jack member 18 with the lower end of the supporting member 12.

A series of connector or brace-supporting pins 22 are arranged in the channel-shaped lift or jack member, and they are spaced apart near the upper or outer end of said member and have opposite ends thereof fastened to the opposite flanges 19 of said lift or jack member.

23 designates a brace member by means of which the lift or jack member is maintained in desired angular relation to the supporting member 12. This brace member is also constructed of sheet material, preferably of heavier gage than the supporting member 12 and the lift or ack member 1S so that it will support a plank or similar object. The

lift or jack member 1S is preferably oi' somewhat heavier sheet-metal gage than said snpporting member.

One end of the brace member is curved upon itself totorm an eye 2i and the other end is bent upon itself to form a hook 25.v The eye 24e of the brace member .i3 is positioned between the lugs 14 onv the supporting member 12` and the openingthrough said eye is in registration with the holes 15 in said lugs; and through these openings is passed a pivot pin 2G serving to pivotally connect the inner or upper end of said brace member with said supporting member. l

With a `1View of utilizing comparatively little space when not in use, and torronvenience in transporting the brackets or jacks, they mayV be folded as shown in Figs.

3 and l; the brace member 23 beingl swungdownwardly or inwardly against the supporting member 12, after which the lift or jack member l1 8 may also be swung downwardly or inwardly Vagainst; said supporting member` completely concealing the brace member. lVhen in` this position the device can be easily applied to a roof, it simply being necessary to provide the nails 11, one tor each of the notches 1G, and hook the supporting member onto said nails, as best shown in Fig. 3. The lift or supporting member may then be swung' on its pivot 21, and while holding the same in angularv relation to the supporting. member, the brace member 23 may be swung on its pivot to engage the desired pin 22 oi the lift or brace member, the pin selected being preferably the one that will dispose thebrace member in a horizontal position, or approximately so.

The free end of the hook 25, as clearly shown in Fig. 2, will be positioned between the fiat outer wall 27 of the lift or jack member 18 and one of the connect-or pins 22, and thus make it necessary to exert pressure manually in a vertical direction while gradually swinging the lift or jack member inwardly or toward the supporting member. Vhen a plank is laid upon the brace members of two spaced brackets or jacks, the tendency ot' the hook ends of the brace members is to more securely lock themselves to the lift or jack members, and this tendencyv is increased underthe Weight of workmen moving about on the plank supported by said brace members.

Having thus described my invention, what I claim is:

Y 1. A roof bracket, comprising a supporting member, a jack member pivotally connected to said supporting member, a brace member pivotally connected to said supporting member, and means for detachably connecting said brace member to said jack member at diierent points along the length of the same, said jack and brace members being foldable one over the other on and parallel with said supporting member.

2. A roof bracket, comprising a supporting member, a jack member pivotally connected to said supporting member, a brace member pivotally connected to said supporting member, and means for detachably connecting said brace member to said jack member at different points along the length of the same, said jack and brace members being foldable on said supporting member and said jack member concealing said brace member when both are in folded position.

3. A roof bracket, comprising a comparatively narrow thin supporting member adaptedto lie against an inclined surface and having means for attachment to said inclined surface, said supporting member being provided at one end'with an eye and between its ends with a pair of spaced lugs, a jack member pivotally connected at one end to the eye of saidsupporting member, and a brace member having one end disposed between' said lugs and pivot-ally connected thereto, said brace member having its other end detachably connect-able to said j ack member at different points along the length of the same and beingv foldable onto said supporting member and said jack member' being foldable onto said blace'member.

4. A roof bracket comprising a supporting member formed of narrow sheet material curved upon itself at one end to form an eye, a jack member also formed of sheet material bent into channel formation in cross section and having the flanges thereo` lying against opposite ends of said eye, a pivot pin passed through said eye and the flanges of said jack member to pivotally connect Vthe latter with said supporting member, a series of pins spanning the space between the flanges of said jack member along a portion of its length, and a brace member pivotally connected to said supporting member between its ends and having a hook at its outer end adapted for selective attachment to the pins of said jack member.

5. A roof bracket, comprising a supporting member having an eye at one end, means of attachment near its other end and a pair of spaced lugs between said ends, a brace member having oneV end disposed between said lugs and pivotally connected thereto and having a hook at its other end, and a jack member of channel formation having its anges lying against opposite ends of the eye of said supporting member andbeing pivotally connected Athereto, said channel member having connector pins spanning the flanges of said jack member and spaced from the outer wall thereof, the hook of said brace member being adapted to engage any of said connector pins and be positioned with its outer end between the selected connector pin and the outer wall of said 'jack member.
