Improvements in Crimping Machines for Joining the Ends and
Bodies of Sheet Metal Cans.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby
declare the nature of this invention, and in what manner the same is to be
performed, to be particularly described and ascertained, in and by the following
statement:—
My invention has for its object the production of a machine for operating on the
heads or ends of cans or other sheet metal bodies, in which the action of the
machine is entirely automatic.
The improved machine is capable of several variations to fit it for the particular
class of work for which it is employed. In the present case I have described a
machine adapted to "crimp" the ends of a can on to the body, that is, to press the
Hange on each end or head against the side or body so that the can with its ends
can be run through a suitable solder bath and properly soldered. The invention
consists in a combination of devices and appliances hereinafter described.
In the accompanying drawing
Figure 1 is a side elevation of a machine embodying my invention.
Figure 2 is an end elevation with parts in section.
Figures 3 and 4 represent the cau before and after crimping.
In carrying out the invention A represents a suitable base plate and A' the
uprights or standards carrying a shaft A' the latter supporting two wheels or
disks B. Each of these wheels or disks is partially surrounded by frames C-C.
D is the can to be treated, the ends being shown at D'. Each of the latter is
provided with a flange d by means of which the end is engaged to the body. This
is accomplished by applying pressure to the flange, thus causing it to lay close to
and engage the body. E is a chute preferably inclined in which the cans are
placed and down which they roll, and F is an outlet for the cans after treatment,
Each of the wheels B is
there being guards or fenders e- to direct the cans.
provided on its periphery with a flange band with a lining b' made adjustable. On
each frame C is a corresponding lining c. These linings are adapted when the
can is inserted to bear on the flange d of the can end, and said linings are therefore,
preferably although not necessarily, slightly convex on their surface so that a
corresponding concave finish is given the flange d.
The operation is as follows: A can is placed on the chute E and rolls down
until it enters the space between the wheels B and the stationary frames C. The
wheels are revolved from any suitable source of power as for instance from the band
wheels G. The can coming in contact with the revolving wheels is rolled around
until it reaches the outlet F. This causes the flange d to adhere closely to the
body and if desired, locked there by giving it a concave face as shown in Figure 4.
If desired (although it is not necessary) the space between the wheels and the
frames C may be narrowed slightly at the discharge end, thus causing the flange to
adhere still more closely. To take up the wear I preferably make the lining c

times happens that where the lining is made convex to indent the flange d or
crimp "it, as it is known to the trade, it is desirable if the flange is a wide one,
to crimp it at another point than is the case with a narrow flange. To accomplish
this, provide the set screws whereby the lining can be adjusted along the can.

page_text: It is of course obvious that as many of the wheels B as is desired may be
mounted on the shaft A2, thus increasing the capacity to any extent desired. It
is also obvious that the machine can be adjusted to various lengths of cans by
adjusting one wheel B and its accompanying frame C toward or from the other
wheel.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :---
1. In a machine for engaging the ends to the bodies of sheet metal vessels, the
combination of two curved sections movable with respect to each other, the curve
of one being substautially conformed to the curve of the other. said sections
constructed to engage the same end of and to roll the vessel between them, one or
more of the sections being provided with a crimping flange laterally adjustable on
the body of the section, substantially as described.
2. In a machine for engaging the ends to the bodies of sheet metal vessels, the
combination of two curved sections movable with respect to each other, the
curve of one being substantially conformed to the curve of the other, said
sections constructed to engage the same end of and to roll the vessels between
them, one or more of the sections being provided with a crimping flange radially
adjustable on the body of the section, substantially as described.
3. In a machine for engaging the ends to the bodies of sheet metal vessels,
the combination of two curved sections movable with respect to each other, the
curve of one being substantially conformed to the curve of the other, said
sections constructed to engage the same end of and to roll the vessel between
them, one or more of the sections being provided with a crimping flange both
laterally and radially adjustable on the body of the section, substantially as
described.
4. In a machine for engaging the ends to bodies of sheet metal vessels, the
combination of a revolving wheel section and an outer stationary frame section
partially surrounding the wheel and conforming substantially to the curve thereof,
said wheel and frame being a distance apart and adapted to engage the same
end of and to roll the vessel between them, one or more of the sections being
provided with a crimping flange laterally adjustable on the body of the section or
sections, substantially as described.
5. In a machine for engaging the ends to bodies of sheet metal vessels, the
combination of a revolving wheel section and an outer stationary frame section
partially surrounding the wheel and conforming substantially to the curve thereof,
said wheel and frame being a distance apart and adapted to engage the same end
of and to roll the vessel between them, one or more of the sections being
provided with a crimping flange radially adjustable on the body of the section
or sections, substantially as described.
6. In a machine for engaging ends to bodies of sheet metal vessels, the
combination of a revolving wheel section and an outer stationary frame section
partially surrounding the wheel and conforming substantially to the curve thereof,
said wheel and frame being a distance apart and adapted to engage the same eud
of and to roll the vessel between them, one or more of the sections being provided
with a crimping flange laterally and radially adjustable on the body of the section
or sections, substantially as described.
7. In a machine for engaging the ends to the bodies of sheet metal vessels, the
combination with a single shaft of two wheel sections mounted thereon and two
stationary frame sections partially surrounding the wheel sections and conforming
substantially to the curve thereof, there being one set of wheel and stationary
sections for each end of the can, said sections provided with a crimping flange
terally adjustable on the body of the section, substantially as described.
8. In a machine for engaging the ends to the bodies of sheet metal vessels, the
combination with a single shaft of two wheel sections mounted thereon and two

substantially to the curve thereof, there being one set of wheel and stationary
sections for each end of the can, said sections provided with a crimping flauge
laterally adjustable on the body of the section, and the flanges on the stationary
frame being also laterally adjustable, substantially as described.
9. In a machine for engaging the ends to the bodies of sheet metal vessels in
combination of a revolving wheel and a stationary frame partially surrounding the
same and located a distance therefrom, thus forming a path through which the
vessel is rolled, one of said parts provided with a crimping flange, the discharge
path being narrower than the entrance, substantially as described.
