SHEET-METAL HANDLE FOR BAG-FRAMES AND THE LIKE.

Specification of Letters Patent. Patented NOV. 14, 1916.

Application filed June 25, 1914. Serial No. 847,177.

To all whom it may concern:

Be'it known that I, WILLIAM A. Loan, a

citizen of the United States, residing at useful Improvements in Sheet-Metal Handles for Bag-Frames and the like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention relates, generally, to improvements in hollow metal handles for bagframes, and the like; and, the present inven tion has reference, more particularly, to a sheet-metal handle for bag-frames, the handle being made from a single piece of metal, cut in the form of a blank and then bent in a manner, substantially as will be hereinafter more fully set forth, with the longitudinal edges of the handle brought together at the top of the handle, with a view of providing a handle which is substantially round in cross-section and provides a perfectly smooth carrying or gripping surface upon the under surface-portion of the handle.

The invention has for its principal object to provide a novel and simply constructed sheet-metal bag-frame handle of the general character hereinafter more particularly set forth and in which, as has been stated, owing to the omission of the usual seam, the under portion of the handle is provided with an unobstructed and perfectly smooth carrying surface, so that all rough portions and sharp edge-portions, sometimes located at the seam, are fully avoided.

Other objects of this invention not at this time more particularly enumerated will be clearly understood from the following detailed description of the present invention.

With the various objects in view, the present invention consists, primarily, in the novel sheet-metal handle for bag-frames, and the like, hereinafter set forth; and, the invention consists, furthermore, in the details of the construction of the handle, as well as in the novel method of making the same from a flat metal blank, and Success sively bending the blank into shape to provide a complete hollow metal handle having the usual seam upon the top of the handle, instead of upon the bottom or side, as heretofore.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a top-edge view, and Fig. 2 a side view of sheet'metal handle made according to and embodying the principles of the present invention. Fig. 3 is a transverse vertical section of the metal handle said section being taken on line 33 in Fig. 1. Fig. 4 represents the blank cut from the sheetmetal. F'g. 5 represents the same after it has passed through the first operation, and Fig. 6 is a transverse vertical section of the same, taken on line 66 in said Fig. 5. Fig. 7 represents the partially bent blank after it has passed through the second operation; and Fig. 8 is a fragmentary transverse vertical sectional representation of the handle, said section being taken on line 8-8 in said Fig. 7

Similar characters of reference are employed in all of the said above described views, to indicate corresponding parts.

In the construction of my novel metal bag-frame handle, a blank 1, see Fig. 4, is stamped or cut from sheet metal, the said blank consisting of a flat strip, tapering along its marginal edges and in opposite directions from the middle toward the ends of the strip, as at 2. At the same time. narrow straps 3 are formed at the ends, substantially as illustrated in said Fig. 4 of the drawings. The blank 1, thus provided, is first bent into the shape shown in Figs. 5 and 6, assuming also the general curvature of the handle which is to he provided, with the longitudinally extending edge-portions 4 extending in the manner shown and flaring slightly outwardly as illustrated more particularly in Fig. 6. The next operation is to bend or curve the said longitudinally extending and slightly outwardly flaring edge-portions 4 into the form represented in Figs. 7 and 8 of the drawings, so that the said edge-portions 4 will curve inwardly, as at 5, but not suflicientlythat the marginal edges 6 will meet, still leaving an open space 7. At the same time, the end-straps 3 are curved upon themselves, so as to form the usual receiving eyes 8. The next and final step in the operation of making the handle is to further close up the edge-portions, until the marginal edges 6 meet, thereby C0111- pleting the hollow handle and providing the same upon its outer curved surface-portion with the longitudinally extending closed seam or joint '9. hen thus completed, and

as clearly illustrated more particularlyin Fig. ot the drawings, hollow sheet-metal handle for l:-ag-irames,andthe like, is provided with an unobstructed, rounded, and seamless gripping or carrying surface, as 10,

l and the seam or o nt 9 being upon the top instead of the bottom or side, as heretofore,

there is no danger of cutting the hand due when the handle is made of thin sheet-metal,

is thus avoided, for in the present construction, no matter how great the-weight which is to be carried by the handle, the seam being upon the top there is always the tendency to still further close the seam.

The handle, as will be clearly evident,

when completed is extremely neat, durable and cheap, and, furthermore, the handle is very light.

1 claim A hollow metal handle for bag-frames and the like made from a single piece of sheet-metal consisting of a strip having tapering marginal edges extending in opposite directions from the central portion of the strip to the ends thereof and formed with upwardly projecting and longitudinally extending edge-portions, and a narrow strap at each end of said strip,said straps forming integral parts of the ends 'of'the strip, said straps extending into and between said longitudinally extending edgeportions at the ends of the said strip, and

' said straps forming receiving eyes and having their free end-portions bent down upon the inner surface-portions of the ends of the said strip, substantially as and for the purposes set forth.

In testimony, that I claim the invention set forth above I have hereunto set my hand this 24th day of June, 1914.
