PHILIP JACOB LACK, of Westmoreland Place, City Road, in the County of
Middlesex, Manufacturer. " IMPROVEMENTS IN THE MANUFACTURE OF METAL
FRAMES FOR TRAVELLING BAGS AND OTHER LIKE ARTICLES, AND IN LOCKS FOR THE
SAME
"
My said Invention relates to metal frames for travelling, dressing, and other bags,
and is designed to furnish frames for such purposes, which will be more simple and
less costly to manufacturers, and will be stronger, lighter, and more durable than
bag frames as heretofore constructed. These frames consist of small bars, L shaped,
in transverse section, and curved to suit the configuration or contour of the top or
mouth of the bag, one part or half of the frame being secured to each side of the
bag. According to the usual method of manufacture each of these parts of the
frame has been formed of two separate strips or flat bars of metal placed together
at right angles to each other and secured by riveting. But according to my Invention
I construct the said frames, or each part thereof, of a single strip or bar of iron or
other suitable metal.
In practicing the said Invention I proceed as follows, that is to say, I cut or stamp
from a sheet or plate of metal a strip of the proper length and width to form the
frame; then I form the joints or connections whereby the two sides of the frame
are to be hinged together, and then bend the said strip or bar to make it conform to
D...li

page_text: the required shape or configuration of the top or mouth of the bag; then I bend or
turn over the said strip or bar to give it the required ✓ shaped cross section by
means of dies or other suitable implements throughout its length, and form in it
suitable holes or apertures for facilitating the attachment to it of the leather or
other material of which the bag may be formed.
My Invention also relates to locks for travelling and other bags. According to
this part of my Invention I provide means for fastening the bag not only in the
centre, but also at or near its ends, or midway between its centre and ends. For
this purpose I construct a lock from whose ends project two sliding bars or -bolts
which extend to and are guided in two small brackets or hole plates attached to
the same side of the frame as the central portion or body of the lock. On the
opposite side of the said frame are fixed two similar plates or brackets formed with
an eye or hole in the proper position to receive the end of the bolts when the bag
is closed, and the bolts are projected or pushed forward. The inner ends with these
bolts are formed, or provided, or combined with catches or hooks with bevelled
extremities for entering sockets or holes in plates, properly arranged for entering
the lock when the bag is closed for fastening the central part of the said bag. For
operating these bolts I provide the lock with a cam piece whose inner end is
arranged in connection with projections on or apertures in the said bolts, so that
when the said cam piece is turned it will draw back the said bolts against the
pressure of a spring. The said cam piece is provided with a head outside the top
of the bag whereby the said piece is turned; or instead of arranging the said cam
piece to operate the bolts by turning the same I may arrange it to act by its
depression, or by pulling it outward. A keyhole is formed through this cam piece,
and by means of a key inserted in the same the bag can be easily locked and
unlocked.
