This machine combines within itself all the parts requisite for the putting together and fitting into their proper places, true and exact, all the different portions of a carriage wheel, and the operation is very simple It is intended to be worked by hand, although it can be operated by power if necessary, or should there be power already in the shop where it is fixed Our engraving is a perspective view, and from our description of the operation, the machine will be thoroughly understood A is a frame combined with the two frames, A' Each of the frames, A', has a block, I, thai can slide along it, and carry face plates, L, through these blocks and face plates pass screws, J, which are operated by the hand wheels K, or by the crank, h, which is on one of them Between these face plates, L, with the screws passing into the center of the hub, the hub is placed and screwed up firm and secure On the frame, A, is a block, B, which can be moved to any position on the frame and held there by a bolt and nut, from a plate on this block rise two pillars, C, that serve as journals for the axle, d, to which is attached a long lever, D, and this axle also carries a small segment, E; a toolholder, F, is free to be rotated through the journal,y, by the handle and gear, G, or to be moved back and forth only by the motion of the lever, D The first operation is, of course, boring and mortising the hubs, which is performed by putting jp an auger into F, and letting the lever, D, by X its own weight, give it the necessary feed; the f C handle, G, is then rotated, and a hole is bored Kgin the hub The distance which the holes are W? to be apart is regulated, so that each is an equal distance apart, by a stop on one of the face plates, L The boring being complete, the auger is removed, and a mortising chisel put in its place F is prevented from rotating, but allowed to slide, and the mortising motion is given to the tool by means of the lever, D, and segment, E, and the hub is fed to the chisel by the large wheel, K, which pushes the hub, face plates, and blocks, I, along, or draws them back when the nut of the other screw is removed Both the screws, J, being now put in gear, the hub is placed in its proper position, and the spokes taken and driven in; they are adjusted, and have the necessary dish given them by means of the guide, , which is supported by thebaTr, N, from the frame We should also state that the bevel of the mortise is adjusted by moving the plate from which C rise on B until the right angle is obtained, and then fastening it by a peg The spokes, M, being now all driven home, a hollow auger is fitted into F, and a clutch or support for the spoke placed on A, and by rotating the handle, G, the tenon, m, is cut on the end of the spoke ; when these are all cut, the wheel is removed, and the piece, H, is placed on the frame, E This piece, H, admits of the felly being correctly bored, by means of the clutch, h, and the handles, h', it is held quite secure and firm during the boring The hub can be bored for the axle box, by fitting a small tool on to the screw, J, and passing it inside, and rotating it by means of the handle, lc We have seen the hubs bored and mortised, the spokes driven in and tenoned, and the fellies bored, of three sets of wheels, or six large wheels and six small ones, in between six and seven hours by one man in one of these machines An extra piece can be supplied so that they will be applicable fur any kind of mortising, and with little trouble one of them can be transformed into a lathe We believe that it is one of the most useful machines for carriage builders and wheelwrights ever yet produced It is the invention of C H Guard, of Burlington, Vt, and was patented by him Oct 20, 1857 Any further particulars can be obtained by addressing him as above, or S C Hills, No 12 Platt street, New York A machine can be seen in operation at Messrs Brewster Co's extensive carriage manufactory, NOB 372 and 374 Broome street, this city
