Letters Patent No. 98,072, dated December 21, 1869.

IMPROVEMENT IN MANUFACTURE Oli-" SCCOPS.

The Schedule referred to in these Letters Patent and making part of the name.

To allvhom 'it may concern Be it known that I, J. GEORGE KN-Arr, of Woodhaven, in the county of Queens, and State of New York, have invented a new and useful Improvement in the Manufacture of Scoops; and I do hereby declare that the following is a full, clear, and exact descripl tion thereof, which will enable othel's skilled in the art to make and use thcsame, reference being had to the accompanying drawings, forming part of .this speci fit-ation.v y

This invention relates to an improved mode of manufacturing sheet-metal flour, grain, and other scoops, and consists in forming the bowls in one piece of metal, without seams or joints, by stamping up sheets of metal into the form of troughs, with a ange around the top, and cutting the same transversely in the centre into blanks for the bowls of two scoops, to be finished by trimming or shaping the cut ends, turning down the flange at the top, for stiffening, 'either over wire or not, and attach in g the handles, the object being to produce scoops with bowls formed in one piece, and shaped smoothly at the base, or the part where the handles are connected, and to ei'ect an economy of labor by stamping. two blanks at one `blow ot' the drop-press, and also to control the metal under the action of the press better in shaping the deep curved part at the base, s as to upset and st-ffen the blanks thereat.

Figure 1 is a perspective view of a iour or sugar scoop made according to my improved mode of operation, and

Figure 2 is a perspective view of the blank for two scoops, as it is delivered from the drop-press.

I take sheets of the metal I propose to use, of any ductile kind, and in the forms and dimensions required for the production of two scoops, and gtrike them up in suitable dies prearranged for the purpose, into the trough-form represented in fig. 2With the horizontal flange or margin A extending around the same.

Ithen cnt these blanks transversely at the centre s by any suitable means, and trim or dress the ends so cut as preferred, and attach the handles of any sortin any approved way, and finish the top lby turning the flange A down, either overa wire or against the side of the bowl withoutthe wire.

This mode of forming theblanks has-the advantage of so controlling that part of the metal which forms the sides B, and alsojthe bottom part G, that it is upset and stilened to aigre-atei' degree in the curved base D where the greatest strength is required.

If struck up in separate blanks for each Y scoop, the sides B will bethrnst forward by the action of the dies in bending up the part D in the direction of the open' end, and the metal will not be thickened t0 or upset thereat, as in this case, where this force is im# parted tot-11e sides from each' end equally, whereby it part D.

Having thus described my invention,

is counteracted in a way to canse the upsetting at the I claim as new, and desire to secure by Letters
