' MACHlN FOR FOLDING SHEET METAL. i
No. 821,765. Specification of To @ZZ-ankam, t may concern:
Beit known that I, ELMER- W. TALMADGE,
. a citizen of the United States of America, re-
siding at Plantsville, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Machines for Folding Sheet Metal, of which the following is a specification.
My. invention relates particularly to machines for working metal, particularly machines in which. sheet metal is subjected to 'v rolling, folding, and similarbending operations, and particularly toV a novel form of gage against which'the stock may be fed to determine the point ati/which the Jfold or roll sha-ll occur.
In the drawings, Figiire lis a vertical section through the gage and the bed of the mai achanneld in the bed c and is` reci chine. f Fig. 2 vis a side elevation of the gage. Fig. 3 is a plan view of the gage. 1 T have illustrated invention as applied to` an ordinary bending-machine, .such as is used by tinners for forming locks or wire rolls in sheet-tin. v` j y The machine'is indicated in general at a. denotes in general the gage, which in the 'preferred form is m-ade separate from the-bed of the machine and is secured thereto in any- This gage rocated by the lever f, 1n a manner Whlch wil be more described hereinafter, to 'advance the v gage-platel onto the table of the `folding-machine, so that the stock., vwhich is indicated by against Vthe gage'- ig. l: The'gage proper comprises the bed-piece e, which is channeled, as at d, and in this channel is located the platev c. The plate is mor- On the under side'of the bed aretwo depending. ears i, between which the L-lever j is pivoted, one end of the lever being'formed into cylindrical shape and adapted to 'lit into the mortise h in the gageeplate.
cap 7c isv secured to the bed and holds the gage-plate in place. The gage-plate is not quite as broad asthe channel 1in order to provide room 'for' a gib l, which may be ad- Letters raient. Patented May 29, 190e.
Application Ifiled June 24,1905. Serial No. 266,862.
vanc'ed by the screws 'In to take up the wear and is also pressed forward by the thumb sired position of adjustment` Thev cap 'is slotted, as at o, and one side ofthe slot is prothis slot in the cap, cooperating. with the graduations along the edge of the slottoperdetermine the size ot the fold. ln the torward end of the channel in the bed there are in recesses u in thel bed, these pins exerting der to keep its forward edges in contact with the table of the foldingmiachine to prevent the stock from riding up over the gage-plate.
The channel-bed, in which the gage-plate slides, may be made integral with the frame oic the machine but I prefer to .ma-keit separable therefrom.
Tn operation the met al g, lying on the tolding-leaf a2, is pushed. under the bending-y plate (1/ until. it comes against the gage-plate c. handle c3 and carried over until it lies onv the beveled surface ci the bending-plate c. The dotted lines show thefioldingdeai in aboutmid-position. ,l
A levice of this character constructed -in accordance with my invention is cheap and very quickly operated and has a decided advantage in that the gage-plate 4may be quickly moved from one position to another. I claim as my inventionl. The combination Iwith a metalavorking 2. The combination with a metal-working vided with graduations-p. An indicator fr is' carried by t-he gage-plate and projec-tsjmto The ioldingeleaf a2 is then raised by the screwn' in order to lock the gage in any demit of the accurate adjustment of the gage to located pinse, which rest on. springs t, located an upward pressure on the gage-plate in or y.
