This invention relates broadly tosheet metal drums, and more specifically a form of seam whereby the terminal edges of a drum body and its head are permanently attached. z
The primary object of the invention is to provide, in a sheet metal shipping drum, a body andea head connected to form asub- Stantial chime joint or seam which will successfull withstand the rough handling to which such shipping drums are ordinarily subjected. V e,
A further object is to provide a chime joint for the ends of drums'which possesses relatively great strength and resistanceto distortion and which, consequently, is substantially leak proof. I c
A still furtherobject is to provide a prac; tical method" for performing the seaming or joint forming operatiori.
a In describing the invention in detail, reference is herein had to the accompanying drawing, in which-- K Figure 1 is a fragmentary top plan view of an end ofa drum embodying myinven-. tion;
Figure 2 is a vidw of the drum partly in vertical section and partly in side elevation;
Figure 3 is a detail section of 'the head end of the drum showing the relative positions occupied by the drum body and head prior to performance of the seaming, or joint-forming, operation; and
s Figure 4'is a similar section showing the parts at the completion of said operation. I Referring to said drawing, 1 designates a sheet metal drum body which has formed therein at a spaced distance from the ter- 0 min'al 'ed e of its end an'inwardly directed annular fie beadconstitutes a seating ledge or shoulder 2" for a sheet metal head- 3 which, prior to the a is to the body 1, has an upstanding annular flange 4 fitted snugly; within the embrace of the marginal edge of the 'body, as'shown-in Fig. 3 of the drawing. Formed'insaid head 3 prior to/insei'tion thereof to its seated position within the end u portion of the flange 4 of the head is curled chime.

In the seaming, or head attaching, operation, effected by means of seaming rollers 6, 65 shown in dotted lines in Figs. 3 and 4, the said end, or marginal edge, of the body 00- cupies inwardly turned oblong chime form, being bent to'provide an outer upright memher 7, an inwardly curled roll ortion 8 and a vertical downwardly directe terminal le 9, the edge of the latter being receive against theouter side of, or behind, the

is dis osed within the channel of the bead 2 inc osely underlying relation to the seating ledge or shoulder 2. Said ring constitutes a rigid support which prevents communication to the body. of the drum of th force exerted!) said seaming rollers, What is claimed is- 1. The'method ofapplying heads to sheet metal drum bodies 'comprisin providing a' drum body with aniinwardly irected annular bead at a-spaced distance. from its end, inserting a head in seated relation to said bead, said head havin an outwardly directed head flange close y embraced by said 190 from its end, inserting a head in seated relation to said bead, said head having an outwardly directed flange closely embraced by said body and also having therein an upwardly pressed circular bead located adjacent to said flange, supporting the seatforming upper part of the body-bead, then turning inwardly and downwardly both the end of said body and the flange of said head and disposing the terminal edge portion of said end vertically behind the bead of the head, and finally thrusting the metal of the last mentioned bead outwardly into seated bracing relation to said vertical edge portion. a
3. The method ofapplyingheads to sheet metal drum bodies comprising providing a drum body with an internal shoulder at a spaced distance from its end, seating upon said shoulder a sheet metal head having an outwardly directed annular flange and having a rib-like portion adjacent said flange, then turning inwardly and downwardly the projecting end portion of said body to a position in which it is disposed parallel to and at a distance from said flange with its terminal edge adjacent to the (plane of said head, and then thrusting into abutting bracing relation to the inner side of said terminal edge portion said riblike portion.
4. The method of applying heads to sheet metal drum bodies, which comprises providing a drum body with an inwardly directed annular bead at a spaced distance inserting a head in seated relation to said bead, said head having an outwardly directed head flange closely embraced by said body, supportin the seat-forming upper part of said body-bead, turning said end and said flange inwardly and downwardly to bring said end into engagement with said head, and then moving a portion of the head metal outwardly into supporting engagement with said end.
In testimony whereof, I afiix my signa ture in the presence of two subscribing witnesses.
' CHARLES H. ROLLASON.
from its end, inserting a head in seating relationship to said bead, said head having an outwardly directed flange closely embraced by said body and also having therein an upwardly pressed bead adjacent said flange, supporting the seat-forming upper I art of the body-bead, and then turmng inwardly and downwardly both the end of said body and the flange of said head and 7 disposing the terminal edge portion of said end vertically behind and in supporting relationship to the bend of the head.
