UNITED STATES PATENT OFFICE.

AMOS JONES, OI! LEBANON, NEW HAMPSHIRE.

ROOF-BRACKET.

Specification of Letters Patent No. 30,325, dated October 9, 1860.

To all whom it may concern.

Be it known that I, AMos JONES, of Lebanon, in the county of Grafton and State of New Hampshire, have invented a new and Improved Bracket for the Roofs of Houses; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which Figure 1 represents two brackets, and the manner of applying them to the pitched roof of a house. Fig. 2 is an enlarged side view of one bracket properly set for use. Fig. 3 is a top view of Fig. 2.

Similar letters of reference indicate corresponding parts in the three figures.

This invention is a new and improved bracket for pitched roofs, to be used thereon for roofing, slating or for any kind of work where men are required to remain on the roofs, any length of time, for the accomplishment thereof.

The invention provides for forming a strong and safe staging for roofs that are very slanting, that may be applied to any roof, or removed therefrom in a short time, and without comparatively any labor.

To effect these ends my invention consists in affixing to one end of a piece of timber of a suitable length a peculiarly constructed adjustable clamp, that will clamp the piece of timber to the edges (butts) of the shin les or eaves of the roof, as will be hereina ter described; and in hinging to the other end of this piece of timber astrong resting bar which is provided on its under side with a rack, and supported by a hinged prop stick, as will be hereinafter described, on which bar is placed, and, if necessary, secured a wide board which when properly supported by a number of the brackets form the roof staging on which persons may stand to do any work on a roof.

To enable those skilled in the art to fully understand my invention I will proceed to describe its construction and operation.

In the drawings, A represents a strong strip of wood or metal, the former being preferable, of several feet in length, to one end of which is secured two clamping plates a, a, that may be opened or closed by suitable set screws b, b. The plates are made so as to slide along the strip A, and be set at any required point by a screw 0. At, or near to the opposite end of the strip A, is hinged a resting bar B, provided on its under side with a rack plate C.

D is a prop, that is hinged at any suitable intermediate point between the ends of strip A, the end of which is pointed and shod with iron; this prop will support the resting bar B, at any angle with the strip A, desired.

This gives a description of the construction of my roof bracket which, it will be observed, is exceedingly simple and inexpensive.

In Fig. 1 two of these brackets are used, the sticks A, of which are jointed together; this combination of brackets may be made, and several may be thus jointed together and made capable of folding up and occupying very little room. In this case one clamp will serve for securing several brackets to a roof, to be used where it is not wished to adjust them often.

The manner of moving the brackets is as follows :The strip A, is laid on a roof, as represented in Fig. 1, and clamped at the lower end to the eaves or projecting edges of the shingles, the resting bar B, is then raised to a proper angle with the roof, say a little above a horizontal plane, and supported by the prop C. Another bracket is now laid on the roof at some distance from this first one, and clamped and set up in the same way; and still another bracket may be placed between these two to give intermediate support to a board that is to be laid over the three brackets on the resting bars B, on which board the workmen may safely stand to perform their operations on the roof.

The clamp serves to prevent the apparatus from slipping off the roof. The usual method is to fasten the brackets by nailing to the roof; but this is highly objectionable because the nails perforate the shingles and cause them to split and become leaky and also involve subsequent rapid decay.

My improvement is applicable to wooden, metal, or slate roofs and does not injure or mar them in any manner. It is also quickly and noiselessly attached, adjusted or removed from the roof.

Having thus described my invention, What the manner and for the purpose herein I claim as new, and desire to secure by Letshown and described.
