IMPROVEMENT IN STOVE-PIPE ELBOWS.
Specification forming part of Letters Patent No. 149,975, dated April 21, 1874; application filed February 27; 1873.
To all whom it may concern:
Be it known that we7 JOHN BEOKMANN and JOHN GIBSON, both of Cincinnati, Ohio, have invented certain Improvements in Pipe-Elbows, of which the following is a s'pcccation:
rIhis invention rela-tes to certain improvements in pipe-elbows; and consists in making the elbow from a single piece of metal, which is slotted and lapped with the seam upon the outer curve, and the lapped parts of the slotedges upon the inner curve, forming but two thicknesses and a smooth external surface, and fastened by teats and depressions, as will be hereinafter described.
In the drawings, Figure 1 is a vertical longitudinal section of our improved elbow; Fig. 2, a section on the line y y of Fig. l; and Fig. 3, a plan view of a sheet of metal, representing the slots and teats, Sac.
The letter d represents a piece of metal of rectangular form, which is provided with folds b' at its edge', and with slots e and depressions j', which latter are preferably of a depth corresponding to the thickness of metal, and with teats g g, as shown. The number ot' slots and teats correspond to the number of laps made in the pipe. The sheet-in etal plate d isbrought to a cylindrical form, and the folds b engaged with each other, as shown in Fig. 2, and its slotted edges are lapped over each other, as in Fig. l, to take up the surplus metal, which causes the pipe to assume the elbow shape;
the teats g are then engaged in the depressions f, which holds the slotted edges together.
An elbow constructed asv above described has its seam upon the outer curve and its llapped slot-edges upon its inner curve, forming but two thicknesses of metal with a smooth external surface, by which means the elbow is made with little trouble and expense, and is superior to any heretofore constructed, inasmuch as it is made without riveting. The lapped portions have but two thicknesses of metal, and the seam is made on the outer curve by joining the folds b,`and hence do not have to be slitted, and the laps are not required to be made over the seam, thus greatly increasing the strength and durability ofthe elbow.
Ve claim as our invention- A pipe-elbow made from a single piece of metal, slotted and lapped with the seam upon the outer curve, and the lapped portions of l the slot-edges upon the inner curve, forming but two thicknesses of metal and a smooth exterior surface, and fastened with teats and depressions, substantially as shown and described.
In testimony that we claim the foregoing we have hereunto set our hands this 22d day of February, 1873.
' JOHN BECKMANN.
