Description
imtd Bietet @wat @Wire JOHN GIBBS, OF BROOKLYN, E. D., NEW Y l CALVIN H. CARTER, OF WATERBURY, CONNECTICUT.
Letters Patent'No. 99,309, dated February 1,1870.
To all whom tt may concern:
Be it known that I, JOHN GIBBS, of Brooklyn, E. D., in the county of Kings, and State of New York, have invented anew'and useful Improvement in Cutting Slots in Metallic Tubes; and I do hereby declare that the following is a-full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.
This invention relates to a new and useful improvement in method of cutting slots in metal tubes, having more particular reference to the tubes or sat'esemployed in the use of the endless match,and consists in the use of a die and punch in combination, with a partition-bed and mandrel for making longitudinal slots or recesses in one or both sides ofthe tube, for giving access to the match used, but which 'methodof cuting slots is applicable'to tubes used for'other purposes.
In the accompanying drawing- Figure 1 is a top view, of the die, partly in section, showingthe tube as completed.` y
Figure 2 lis a vertical section of the punch and die through the line :t z'of fig. 1.-
Figure 3v represents a sectional top view of the dieA .without the tube.
Similar letters of parts;
A is the die, which is properly secured on the bed of the press,. having an aperture through it, divided by the vertical partition B, and-supporting a horizontal mandrel, C, by means of afastening plate, D.
This mandrel is placed directly over the partition reference indicate corresponding B', and its gauge or diameter is-eq'ual with the thick' ness of B. The'space between the mandrel and the partition Bis designed to be about equal to the thickthe die-plate, as seen in same iigure.
ness of the tube-metal, but the mandrel is allowed some play, to compensate for the variations in the thickness ofthe metal of tbe tube. The mandrel ts the tube, but is flattened on its sides, so that at the slot it only lits the tube at its upper and under sides.
The tube E is shoved on to the mandrel,` and its forward end enters a hole in the fastening-plate D, as-
supported lby seen in fig. 1, while its back portion vis When thus placed, the tube is ready for the punch, and when the punch descends, pieces are cut from its sides through the tube-metal, making slots in the tube, and leaving the tube as seen in fig. l.
F is the punch, which is worked vertically by foot, or otherwise, the slot g in it being equal to the thickness of the mandrel C, and the partition B. Its inner corners are cutting-`edges, as are the upper angles of the flattened portion ofthe mandrel C, aud upper angles ofthe partition B.
By widening the slot `.g in the punch, and flattening only one side'ofthe mandrel, a single instead of a double slot may be cut in, the tube, should a single slot be required in tubes for any purpose;
' By this arrangement, slots in tubesmay be out of any desired size and shape with the greatest accuracy and expedition. v
Having thus described my invent-ion, v
What I clair as new, and desire to secure by Letters Patent, isy,
In combination with the die A, partition B, and mandrel C, the punch F, all arranged Iand operating substantially as herein shown and described and for the purpose set forth.'
'i JOHN GIBBS.
