GEORGE E. MILLER, OF PAWI UCKET, RHODE ISLAND.

ROOF-BRACKET.

SPECIFICATION forming part of Letters Patent No. 496,483, dated May 2, 1893.

Application filed September 1'7, 1892. Serial No. 446,238- (No model.) I

To all whom it may concern.-

Be it known that I, GEORGE E. MILLER, a citizen of the United States, residing at No. 9 Johnson street, in the city of Pawtucket, county of Providence, and State of Rhode Island, have invented a certain new and useful Improvement in Roof-Brackets, of which the following is a specification.

My said invention relates to a shingling bracket used for the purpose of securely supporting stagings and platforms on roofs and other inclined surfaces, and consists of a solidly riveted framework of steel, or other suitable material, formed in the one part to fit a slanting roof or inclined surface, and of a proper shape in the other part to support and secure the staging or platform placedthereon, and provided with a clamp and hooked spurs to firmly fasten the device to the roof or surface aforesaid.

The accompanying drawings are hereby made part of this specification, similar letters of reference thereon referring to corresponding parts.

Figure l is a plan or top view of the device, showing part of a shingled roof surface underneath, and Fig. 2 is a side view of the bracket and a transverse sectional view of the part of a roof seen in Fig. 1, the bracket being secured thereto and in position ready to receive platform or staging boards to be placed thereon.

a, a a. a represent the shingles on the plane of the roof seen at b b.

The bracket is in two parts or pieces, 0 being the formed base so-curved at one end as to form the loop or clamp d, the end termi mating in two or more hooked spurs one of which is shown at e.

ffff is the shaped frame formed of one piece of stock and firmly riveted to the base 0 d by the large rivets it, while one of its ends is securely fastened to the horizontal planen n by the spur-top rivet is. When the two members of the device are so riveted together as shown they become a firm and solid whole without any movable or sliding parts. The curved or looped endd is so shaped as to form a clamp to fit upon the tapering surface of the end of the lower row of shingles, the weight of the added staging and workmen on the plane a n compelling this clamp to clasp the upward tapering end of the shingles more and more tightly as the weight of, and on, the staging is increased. The booked and sharpened spurs 6, one at each corner of the end of the base beyond the loop d, (and one ormore between these two if desired,) are orced into the row of shingles lying under oath the one clamped by said loop, and penetrate deeper and deeper into it as the strain upon the bracket grows greater.

The manner-of attaching the device to the roof is shown in Fig. 2. The projecting top c is inserted under the upper row of shingles as seen and extends thereunder some four or five inches, and more if desired; the loop or clamp 01 receives theend of the second row of shingles next below the one above mentioned as the end of the base is pushed upward to place. The end of the last mentioned row of shingles will be slightly raised for the purposes described, and when it is released to its former position the hooked and sharpened spurs e at once fasten themselvesinto the row of shingles next below. On an ordinary roof this will leave the plane n n nearly horizontal for the staging boards or platform planks: the spur it will be nearly or quite vertical, and in the required relation to firmly hold the staging or platform aforesaid.

It will be apparent how great strength and security are attained as the hooked and sharpened spurs e sink deeper and deeper into the under row of shingles, reinforced by the increasing grip of the clamp 01 on the tapering ends of the row of shingles next above, and both steadied by the projecting end of the base 0 well thrust between the two upper and independent rows of shingling as shown: and

it will also be clear that the more the weight and strain upon the bracket are increased the stronger and more secure will be the grip and hold of the several parts upon the roof. The device will afford workmen almost absolute safety upon any roof of any inclination, and may be applied and removed with great ease and rapidity. From its simplicity it may be made at small cost, and will last an indefinite period. Its use leaves no injury to the roof 10 Letters Patent, is-

A shinglers bracket made from two pieces of steel, or other suitable material, the base 0 having its end cl looped to form a clamp and terminating in two or more hooked spurs, and the bent frame f f solidly riveted to the base as at z' 2', with its supporting end also firmly secured to its staging plane 71 n by means of the spur-top rivet 70: all of said parts being constructed and combined in the manner and for the uses and purposes substantially as shown and described.
