IMPROVEMENT IN CARPET-BAG- The Schedule referred to in these Letters Patent and making part of the' same.

- provements in the Construction of the Jaws or Frame for Carpet-Bags or Travelling-Sacks; and We do hereby declare that the following is a full, clear, and exactdescription and specification thereof, reference being ha( tothe accompanying drawings, and to the letters of reference marked thereon, like letters indicating like parts Wherever they occur.

In the said drawings-- Figure 1 'is a view in perspective of a bag-frame constructed according to our invention;

Figure 2 represents a portion ofthe sheet-metal strip of which one of the jaws ofthe frame is formed, previous to the bending of such strip;

Figure 3 represents a perspective viewv of a part of one jaw and the adjacent portion 0f the bag; Figure 4 represents a View of thehinge of the frame;

Figure 5 represents a transverse section of the jaws; and

Figure 6 represents a view of the end of the strip of metal cut for the formation of the hinge.

In the manufacture of the frames of travellingfbags or sacks, it has heretofore been customary to construct the jaws or frames of several separate pieces of metal and wood, united by rivets, screws, Src., thus rendering them complicated and expensive, and at the same time not shutting together as compactly and securclyas is designed.

Our invention has for its object the obviating of these objectionable features, and at the same time, while producing a stronger and better article, to also Inake them simpler and cheaper.

In the rst place, it is desirable to form the jaws entirely of metal, having an L-section, in order to give them strength laterally; and, secondly, it is desirable to form them of thin, light strips 4of metal, so bent as to secure great strength and rigidity, without rendering them clumsy or heavy; third, it is an objectto so construct them that each jaw shall-consist of a single continuous strip or piece of metal that can be Wrought into the required form with the least possible amountl of labor; and, fourth, it is desirable that the two `jaws should be iirmly hinged together. j Toacoomplish these objects, we constructeur improved jaws of a single strip cf sheet-metal, as represented by A of fig. 2.

-This strip, which at first consists of a plain, ilat strip,

of uniform width, and of suitable length to form 'a jaw,

has aline, e, drawn longitudinally on it, (as represented in iig. 2,) as a gudealong which it is subsequently to be bent lengthwise, at right angles, to form what 1s termed a boxjaw', a cross-section of which shall be L-shaped,

as shown in fig. 5.

Preparatory, however, to this bending, the point where the corner of the'jaw is to be formed, is indicated by measurement, and a portion of the metal in the part d, whichis to form the perpendicular part of the jaw, is'cut through transversely, while that portion, c, which forms the dat part of the jaw, is not cut.

lhie mode in which we prefer vto cut the metal is shown in fig. 2.

The cut is'inade along the lines ff in straight lines, standing at right angles to each other, tonear the linee.

From the inner extremities of the lines f, the cut is continued along the lines f in a curve,- as shown, and

thence along the line e, from the extremity of one line, f', to that of the other.

After thisoperation is completed at each of the two corners, the strip is bent lengthwise along the line e, so

as to cause theparts c and d to stand at right angles to each other, as heretofore described, and as shown in figs. 3 and 5 The strip A being thus' partially cut through at the comers, and bent lengthwise along the line e, is next bent transversely at each corner, so as to bring the edges f in contact, as shown at g, hg. 3, this bending drawing the part c tightly against ths edges j', and thus forming 'a slightly rounded corner on the outside, as shown in figs l and 3. A

When thus bent into proper shape, the joint at the edges f and e is secured, which may be done by soldering, blazing, or riveting, to render it tight and firm.

One jaw of the frame is made a little smaller than the other, so as to enter into it, as shown at figs. 1 and 5, and the two are connected at their ends by hinges.

We construct the hinge as shown in igs. 4 and 6, said figures representing the form in which the ends of the strips lare cut to form the hinge, and also the hinge, after it is formed and united by the rod a, which should extend entirely across the bottom of the frame,

from end to end, as represented in lig. 1.

I n this hinge the jointrod a not only passes through the thin earsh h, but also through a tube, i, formed by bending the end of the portion d .of one jaw into a tube; and as this tube extends longitudinally along the joint-pin a, a hinge of much greater rigidity is obtained than if the joint-rod or pivot extended merely through the thin ears.

.It will, of course, be understood that tnese cuts, bothl at the corners and at the ends where the hinges are made, may be made by punches or dies operated by machinery, as is usual in working sheet-metal, it only being necessary to have the dies or cutting-tools of suitable shape to make the cuts of the desired form.

It will -thus be seen that by our mode of construction, each jaw may be formed of a single continuousstrip of sheet-metal, which, by a very simple and cheap process,

is formed into a box or L-form transversely, thereby producinga very cheap, strong, rigid, and light frame,

composed entirely of metal.

It will also be observed that jaws thus constructed, when closed, have their inneredges shut past each other, thus interlocking, or shutting one within the other, and as the portions c of the jawsliein the direction in which the jaws close, it is Aevident that they will be very rigidand strong, in proportion to the quantity of metal used, and that they cannot be easily forced open when locked, and will not spring apart, or gape, as the old-fashioned flat jaws usually do.l

The portions d, presenting in like manner their edges, toresist strain brought upon them when standing either edgewise or endwise, will also render the jaws rigid in that direction, and thus tend to prevent injuryfrom weights resting on the bag when travelling, or by its being thrown carelessly about, as is very commonly the.

case with such articles.

We are aware that jaws having the L-shape, asherein desoribedhave previously been made of narrow strips of metal for small articles, said jaws beingfonned by forging or swaging the narrow strip into that form; but it is obvious that strips of sheet-metan, such as' we use for making the jaws herein described, cannot be thus formed andv then bent at the eorners'without great difficulty and danger of breaking the metal, because, in order to give to the jawsthe requisite vstrength and rigidity when formed -of sheet-metal, the portions d c must both be of much greater width than in the jaws used on the n jaw, irrespective ofthe manner of construetingthe saine;

but having thus fully described our invention,

1. A box or L-shaped jaw for a tlavelling-bag, constructed of sheet-metal, partially ont throughtransversel y and bent lengthwise and transversely, substantially as before set forth.

2. Also, the combinationv of a box-jaw, constructed 0f sheet-metal, as before set forth, with a second jaw, of box-form, by means of hinges, the whole forming a complete box-formed frame fora t1avelling-bag, substantially as before set forth.

3. Also, the hinge, constructed by combining the joint-rod with both' an ear and a tubular part of the jaw, substantially as before set forth.
