cfllfrw G. 780% patented July 13, 1926 UNITED sTA-Tss a'r-ssressi same ALFRED Gr. PEEK, BELLWOOD, -SEBRASX1L noon AoK.
Application filed November The invention relates to-r-oof jacks, and has for its object to provide a device of this character, which is safe, simple in construe tion and may be easily and quickly placed on a roof, no matter what the angle thereof,-
vided with acutely angled prongs adapted to imbed in the roof and hold the bar in position. Also to provide the upper-side of the bar with a hinged member adapted to be on gaged by a board, which hinged member has hingedly connected thereto adjacent its outer end a brace, which extends towards the upper side of the bar and terminates in a hinged plate through which a securing bolt passes, which bolt also passes through the bar.
A further object is to provide adjusting means comprising a plurality of apertures through the bar and forming means whereby the hinged member may be adjusted to various angled positions in relation to the bar, according to the pitch of the roof. Also to provide the hinged member with a hook at its outer end adapted to hook over the upper edge of a board and prevent upward displacement of the board.
lVith the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the inv-ention.
In the drawing Figure 1 is a perspective View of a portion of a roof showing a pair of jacks applied thereto.
Figure 2 is a vertical transverse sectional view through a portion-of the roof showing one of the jacks in side elevation.
Referringto the drawing, the numeral 1 designates an inclined roof of a barn, house or other type of building, and 2 the spaced jacks disposed on the outer side thereof. Each jack comprises an elongated bar 3 to the under side of which bar is'secured adjacent its ends by meansof rivets 4, which 10, 1924. Serial is. 748,935.
however may be bolts if desired, plates.
The plates 5 are provided with downwardextending acutely angled prongs 6, which prongs are forced into thev outer side of the roof 1 when the bar is placed in position on the roof. 'Itwill be seen that the prongs 6 will positively holdth e bar against longi- ,t fidinal movement in the direction of the arrow at. Secured to the upper side of the bar 3 at its upper end by means of the rivets a is a plate 7, and to which plate is hingedly connected at 8 an outwardly extending bar 9, which bar 9'is adapted to be disposed at a right angle to the roof 1,-and by'being hinged the bar may vary in relation to the bar 3 and the pitch of the roof, thereby allowing the same to be accurately positioned at a right angle to the roof. The hinged bar 9 at its outer end. terminates in a hook F 10, which hooks over the outer edge 11 of the board 12, and prevents outward displacement or slipping of the board 12, and at the same time the bar 9 forms a brace for holding the board 12 in position, and on which board a workman stands while shingling or repairing a roof,
The hinged bar 9. is provided with a hinged brace 13 connected hingedly at 14: to the outer end thereof, and which brace extends downwardly and inwardly towards the outer face of the main bar 3, and is hingedly connected at 15 to la plate 16, which rests onthe outer face of the bar 3 andis secured thereto bymeans of the bolts 17, which passes through the plate 16 and one of a plurality of apertures 18 in the bar I 3, therefore it will be seen thatthe hinged bar 9 is thoroughly braced and the angle of the hinged bar 9in relation to the roof 1 may be easily and quickly adjusted according to the pitch of the roof. In practice any number of roof jacks may be used, and for purposes ofillustration two are shown in Figure 1. e
From the above it will be seen that a roof jack is provided which is simple in construction, and one wherein the board'supporting arms maybe easily and quickly adjusted to various angles in relation to the roof, and when not in use, the jacks may be formed into a compact package for storage aurposes, or for shipping purposes, by simply removing the bolt 17 and allowing the hinged member 9 to move into engagement with the outer face of the bar 3, at which time the brace 13 and plate 16 will be in edly connected to the inner end of said last named plate and adapted to receive thereon a board, a hooked member carried by the outer end of the second bar and adapted to hook over the outer edge of the board and hold the board in engagement with the plate secured to the upper side of the bar and against outward movement, a brace hingedly connected to the hinged bar adjacent its outer end and extending towards the upper side of the first mentioned bar, a plate hingedly connected to the brace, engaging the upper face of the first mentioned bar and a bolt extending through one of a plurality of apertures in the first mentioned and through said last named plate and a head carried by the bolt and engaging the under side of the bar between the spaced plates.
In testimony whereof I affix my signature.
