IIVIPROVED MACHINE FOR FINISHING SOLDERED- TUBING.

Specification forming part of Letters Patent No. 20,5129, dated June 8, 1858.

To all whom. it may concern.-

Beit known that I, EDMUND J ORDAN, of Waterbury, in the county of New Haven and State of Connecticut, have invented a new and Y useful Machine for Finishing Soldered Tubing;

tached plan view of the clamp. Fig. 4 is a transverse section of the saine, taken in the line y y, Fig. 3.

Similar letters of reference indicate corresponding partsin the several figures.

This invention consists in a peculiar means employed for operating a file or cutter for the purpose of filing or finishing off the soldered seams of tubing.

The invention also consists in a peculiar clamp for holding the tubing while being operated upon by the file or cutter.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a rectangular frame, which may be constructed in any proper manner to support the working parts.

B is a driving-shaft placed transversely in one end of the machine, said shaft having a crank, C, at one end of it.

To the crank C a connecting-rod, D, is attached,the outer end of said rod being pivoted to a bar, E,which is pivoted to a sliding plate, F, said plate being iitted between guides G G, attached to one side ofthe frame A.

To the lower part of the bar E lateral arms a a are attached-one at each side-and to these arms clamps b are fitted, said clamps retaining each a le or cutter, c, the cutters being formed of steel plates, cut on their under or face sides in any proper manner to form cutting-edges, similar to a rasp or file. The connecting-rod D is attached to the barE above the pivot d, which attaches it to the sliding plate F.

On the sliding plate F, or on a projection thereon, two lugs, dd,are formed, and through these lugs or ears screws e epass, between the inner ends of which the upper end of the bar E is fitted and works, said screws serving as stops.

To the upper part of the frame Atwo plates or stops, G G', are attached, the use of which will be presently shown.

H H are two levers, which are pivoted in the frame A, as shown at f.

In the outer ends of the levers H concave journals g of a bar, l1, are fitted, the journals being fitted loosely in their bearings.

To each end of the bar h a cross-plate, i', is attached, said crosslplates being connected with the j ournals,and to the lower parts ofthe -plates i the lower ends of two plates, I I, are

attached-*one at each side of the bar h-the plates I extending upward a little higher than the bar h.

Transverse] y through the plates I I a screwrod, j, passesand a lever, lc, is attached to the outer end of said rod, the inner end of said lever forming a cam which bears against abar,

Z, tted in a slot in the screw-rod j. The levers H H are connected by means of supplementary levers m m to a rod, J, which is attached to a treadle, K.

The operation is as follows: The attendant or operator grasps a tube, L, and places it seam uppermost between the upper ends ofthe plates I I, which, when not otherwise acted upon, are kept distended by springs it. The upper ends of the plates I I are made to grasp the tube L and hold it iirmly by adjusting the lever 7c. Motion is then given the driving-shaft B in any proper way, and the les or cutters c are moved back, and farther over the seam of tube L, the latter being pressed upward against the files or cutters by depressing the outer end of the treadle K. The cutters c act alternately on the tube as the bar E is tilted at the end ofA each movement. The action ofthe rod D serves to keep the bar E and cutters in proper position, and the tilting of the bar E, and consequently the cutters, is assisted in being tilted a little in advance of the action of rod D, by means of the stops G G, in consequence ofthe upper end of the bar E striking against said projections. By this means the device vis made to operate smoothly, the stock, which is fitted to a reciprocating slide, momentum ofthe files or cutters and the cutter- F, and operated by means of the connectingstock being neutralized at the end ofeach stroke rod D, crank C, and stops G G', substantially by the advance tilting movement described. as and for the purpose set forth.

By this inventionthe tubes may be nished- 2. The clamp formed of the two plates I I, that is, have their soldered seams smoothly l attached to the leversHH,Which are connectfiled or rasped in a perfect manner and with ed to atreadle, K, the Whole being arranged to great facility. operate as and for the purpose specified.

Having thus described my invention, what EDMUN D J ORDANv I claim as ne'W, and desire to secure by Letters Witnesses:
