RECENT PATENTS.

TO JAMES HARDY, of Birmingham, in the county of Warwick, Gent., for certain improvements in the process of welding tubes, pipes, or hollow rods of malleable iron, by machinery.-[Sealed 28th March, 1844.]

THIS invention consists in substituting for the apparatus ordinarily employed for making iron pipes or tubes, (consisting of a pair of revolving grooved rollers, mounted in a suitable frame,) a series of three or more revolving grooved rollers, mounted in a frame one above another, between which (that is, between the lower one and the one next above it, and between this last one and the roller next above, and so on) the skelp, previously brought to a welding heat, is passed in succession, until formed into a welded tube of the desired size.

In Plate XIII., fig. 1, is a front view of a machine constructed according to this invention, with a set of three rollers and their appendages; fig. 2, is a back view; fig. 3, a side view; fig. 4, a transverse vertical section; and fig. 5, a partial back view, to exhibit some of the parts more clearly. A, B, C, are the rollers, which work in bearings in the standards D, D: motion is communicated to the axis of one of the 2 N

rollers from the steam engine or other prime mover, by means of a connecting shaft H, and the three rollers are caused to revolve together, at the same speed, by the pinions E, F, G, which gear into each other. Around each roller a number of grooves are formed, gradually diminishing in size from one end of the roller to the other. The grooves in the roller B, are larger than those in the roller a, and the grooves in the roller c, are smaller than those in the roller a, so that, by the combination of the three rollers, two sets of gradually diminishing apertures (nearly circular) are formed, of which the grooves in the lower set are slightly larger than the grooves in the upper set. Or, the centre roller A, may have two sets of grooves in it, one set corresponding with those in the roller B, and the other set corresponding with those in the roller c:' in this case the apertures formed by the grooves would be circular. I, is the mandril that supports the skelp or partly finished tube, while it is being passed through the largest apertures formed by the grooves of the rollers; and N, O, are two discs, fastened upon the stem of the mandril, which come in contact with the plates or stops J, K, so as to retain the mandril in its proper position when the skelp is being acted on by the rollers. The plates or stops J, K, are supported at a suitable distance behind the rollers on a standard L, connected to one of the standards D, by a rod or bolt M.

The movement of the mandril, to bring it opposite the upper and lower apertures between the rollers, is effected by means of a semi-cylindrical trough P, carried by arms Q, Q, on the horizontal axis R. This axis turns in bearings at the lower end of the framing s, suspended from the horizontal axis T, which is supported by the standard L, and bracket u. The hinder ends of the arms Q, Q, are connected by a handle v, and from each arm a pin w, extends, for the purpose regulating the extent of the ascent or descent of the arms, by entering the notches in the plates or stops x, y, which are bolted to the standards D, and L.

The mode of operating with this machine is as follows:The skelp z, (fig. 4), is taken from the furnace at a welding heat, and is then passed between the rollers A, B; the bulb of
