ROOFING-SCAFFOLD.

To all to 710m it may concern Be it known that 1,.SAM HAWKINS, a citizen of the United States, residing at Centralia, in the county of Marion and State of Illinois, have invented a new and useful Roofing-Scaffold, of which the following is; a specification;

The object of my invention is to provide a scaffold for use in applying shingles to the roof of a house, the scaffold being of such construction that a part of the plane sur face of the roof extending from the eaves to the ridge may be shingled without moving the supporting bar or the scallold.

I attain this object by the mechanism illustrated in the accompanying drawing, in which Figure 1 is a perspective view of the scaffold with a portion of one of the foot-pieces broken away; Figs. 2 and 3 are detailed views on a reduced scale and taken at right angles to each other, of the ridgeholder. Fig. i is a detailed view also on a reduced scale, of one of the foot-pieces.

' The main timber or supporting piece 1 is disposed on the roof in a direction extending from the eaves to the ridge, and is supported in spaced relation to said roof by cleats 3, attached to the lower side of said main timher at points adjacent its respective ends. The main timber or supporting bar 1 is provided along each of its lateral faces with spaced apertures 6, adapted to selectively receive the spikes 5 secured in one terminal of the foot-piece 2. Each of the foot-pieces may thus be removably connected with the supporting bar 1 at any desired point in its length. To the outer end of each fot-piece 2 is secured a rope or equivalent flexible element 4 which extends through a hole 14 in the main timber 1 and down along the side of said timber to be looped around a peg 8, secured to the timber adjacent its lower end.

These ropes cooperate with the spikes 5 to hold the foot-pieces in position. The

Specification of Letters Patent. Patented S t 27 1921 Application filed April 8,

1920. Serial No. 372,416.

' upper end of the main timber 1 is reduced in cross sectional area to receive the slotted ridge-engaging post or holder 15, the pin passing through a hole 12 in said post and a registering-hole in the timber to secure the two members together in joint relation. A brace 11 passes through a slot in the holder 15, being pivotally secured thereto by a peg 10. At the lower end the brace 11 is tapered and is received in one of the holes 9 in the main timber 1, to hold the post 15 rigid and in'adjusted position.

I claim:

1. A roofing scaffold comprising a main timber, adapted to extend from the ridge to a point adjacent the eaves ridge-engaging means carried by the upper end of the timber, footpieces each having one terminal provided with a spike, the main timber being provided on its lateral faces with spaced apertures adapted to selectively receive said spikes, whereby said foot-pieces may be re movably secured to said timber in adjusted position, and flexible means connecting the outer ends of said foot-pieces with said timber.

2. A roofing scaffold comprising a main timber adapted to extend from the ridge to a point adjacent the eaves, a ridge-engaging post pivotally connected to the upper end of said timber and projecting upwardly above said ridge, a bracing member adjustably connecting said projecting portion of the post with said timber, foot-pieces, each having one terminal provided with a spike, the main timber being provided on its lat eral faces with spaced apertures adapted to selectively receive said spikes, whereby said foot-pieces may be removably secured to said timber in adjusted roof-engaging position, and ropes connecting the outer ends of said foot-pieces with said timber.
