IMPROVEMENT IN GROQVINQMACHINES FOR SHEET-METAL.
--4o v The Schedhletei'emd to in theseLettem Patent and making oi the same.
To all whom it may concern.-
Be it known that I, CHARLES H. RAYMoNmof Southingtonfin the county of Hartford, and State of Connecticut, have invented and made a new and usei'nl Improvement in Growing-Machines for Sheetand the following is hereby declared to be a full, clear and exact'desciiption thereof.
The grooving-machines that have heretofore. been made for tinmen and sheet-metal workers have had a lower and upper jaw, united together byside plates and bolts. Between those, there is a rack-bar, carrying a roller for pressing the folded sheet-metal together at the joint or seam..
In machines of this kind, the parts are very heavy and costly, in consequence of the jaws being made solid, and of separate pieces bolted together, and any looseness in the bolts allows the jaws to separate at the outer end, and the action of the machine is imperfject. v My invention relates to a hollow cast-iron bed-jaw, formed in one piece with the upper jaw, that is recessedor U-shaped, to receive the sliding rack, and a socket is cast in the lower jaw, to receive the supporting-pin, and the pinion, that acts upon the sliding rack, is received within. a recess in an extension of the under jaw.
By this construction, the jaws are lessened in weight, rendered less costly, and the liability of the parts springing or working loose is prevented.
In the drawing- 7 Figure 1 is a side view of the machine, with part of the jaws broken open, and
s Figure 2 is a cross-section of the line a: x.
The lower jaw a, socket b, side pieces 0, upper jaw d, and bearing 0, for the pinion e, are all cast together.
The lower jaw a is hollow, forming a tapering tube,
that opens into the socket b.
The upper jaw d is recessed upon the under side, so as to be of a n-form, to receiver the upper part of the rack-slide 'i and roller l0, that is set upon a spring, as usual.
The roller Z is sustained in a jaw at the end of the rack-slide i, and the pinion e occupies a recess in the bearing 0. a
' When the pinion cand its shaft are made in one piece, it will be necessaryto have one side of the bearing 0 removable, and attached by screws, as shown.
I claim, as my invention- The grooving-machine, consisting of the tubular tapering jaw a, socket 1), side pieces 0, and n-shaped upper jaw d, slide-rack i, pinion e, and roller l, constructed and arranged relatively to each other, as described.
Signed, this 16th day of December, A. D. 1869.
