IMPROVEMENT IN BOILER-COVERINGS.
Specification forming part of Letters Patent N o. I 85,460. dated December 19, 1876; application tiled January 21, 1876.
To all whom it may concern: I
Be it known that I, FRANCIS B. STEVENS, of the city of Hoboken and State of New J ersey, have invented an Improvement in Boiler- Ooverings, of which the following is a specifi cat-ion: j
My invention consists in an improvement in the description of boiler-covering for which Letters Patentof the United States were granted me November 2, 1875, N 0. 169,492.
Figure 1 shows a horizontal view of a hollow section of metal boiler-covering, with the sheet of metal next to the boiler removed. Fig. 2 shows an end view of Fig. 1. Fig. 3 shows an end view of Fig. if bent to the curvature of a boiler seven feet in diameter. Fig. 4 shows a cross-section taken through the line X X of Fig. 1.
The length of this cross-section is not shown, the two ends being divided by the broken line H H.
I construct the hollow sections of metal thin enough to be bent to a right angle without injury, for which purpose I have found sheet-iron of No. 26, wire gage, and also galvanized sheet-iron of the same thickness, to be thin enough; and I form the flanges E E E E by bending all the four edges of the sheet B. These flanges E E are only shown in the drawing in Fig. 4, on the ends of the plate, the two flanges on the side of the plate being formed in a similar manner. I also form flanges G G G G on all the four edges of the inner sheet A, and I fasten the sheets A and B together by the rivets I I, through the flanges E and G. I make the flanges G only sufficiently long to hold the rivets I, and I make the flanges E project beyond the flanges G, as shown, so that they can readily be cut by hand-shears, and fitted over the irregularities ot' boiler-surfaces, such as rivet-heads and laps of the boiler-plates.
When the hollow sections of metal are to be made to flt over a circular boiler l slit, by shears, the circular flanges E, as shown at L L on Fig. 3, to allow these flanges to bend to the curvature; andI also slit the flanges G G in the same manner.
To strengthen and stiffen the hollow sections, as above described, and to prevent the plates A and B from being forced together, I put ribs of wood K or ribs of iron M inside of the hollow spaces D. I secure these Wooden ribs K to the plates A and B by nails, and I secure the iron ribs M to the plate B by the rivets N.
I claim as my invention 1. The combination of a boiler-covering, made of hollow sections, formed by the flanges Gr bent on'the inner metal plate A, and the flanges E bent on the outer'metal plate B, and fastened together through said flanges.
2. The combination of a boiler-covering made of hollow sections, and stiffened by the ribs K and M, placed in the hollow space D between the metal plates A and B.
