=IO'HN PFEIFER, OF PHILADELPHI A, PENNSYLVANIA.

Letters Patent No. 61,356, dated January 22, 1867.

IMPROVEMENT IN GOAL SCU'ITLES.

TO ALL WHOM IT MAY'CONCERN:

Be it known that I, JOHN PFEIFER, of the city of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in the Manufacture of Coal Hods; and I do hereby declare that the following is a full, clear, and exact descriptiouof the same, reference being had to the accompanying drawings, making a part of this specifioation, in which-- Figure 1 is a side elevation of the improvedcoalhod and Figure 2, a vertical section of partof the same.

Like letters ofreference indicating the same parts when in both figures.

My invention particularly relates to the manufacture of those coalhods which have their bottoms stamped up" in a single piece of sheet metal, aspatented to Thompson, Smith, and Jennings on the 20th day of March,

1866, and afterwards assigned to me.

In the manufacture of the said hods in accordance with their specification it is found to be impracticable, withouttoo much cost-of time and labor, to make a .sufficiently close-fitting joint between the said bottom and the body of the hod, and the object of my improvement is to remedy this defect.

My invention consists in running a concave-convex head around the hod at the part of the same where the said bottomand body overlap each other, substantially as hereinafter describediand set forth,

In the drawings, A is the body of the bed, and B-the bottom of the same. The body A is flanged or flared outward at its lower edge, and the'bottolnB stamped up, slipped within the flared part of the body A, and

then riveted fast by four rivets, substantially as described and set forth in their specification. In this condition the joint is not close, and can be seen through on holding the bottom of the bed up between ones eyes and the light, and, in order to produce a perfectly close joint between the lapping' parts of the body A and the bottom 13, I make the coucavo-convex bead, a b, by means of the well-known beading machine, around the bod, Just below the point or line where the flange starts from the body A, thus compressing the two lapping parts together, and producing a perfectly closed and uniform joint between them around the hod, as shown in the drawings. When a hod thus manufactured is painted or japanned in the usual manner, itwill be watertight, whichjs a conditionrequired in all coal hods.

Having thus fully described my improvement, whatI claim as new of my invention, and desire to secure by Letters Patent, is-- Producing a close joint between the body A and bottom B of 'the said coal hod by means of the concavecdnvex bead a b, substantially as and for thepurpose described.

JOHN PFEIFER.
