APPARATUS FOR BLOWING AND SHAPING GLASS.
SPECIFICATION forming part of Letters Patent .No. 267,962, dated November 21, 1882.
Application filed October 6. 188 2. (No model.) Patented in England March 3, 1882, No. 1, 033..
Our invention relates to apparatus for blow ing and shaping glass heated by the blow-pipe to forms which; are usually those of solids of revolution, the object which we have in view being to insure equable heating of the glass,
and to hold it and move it without undue strains while it is being operated on, so that it can be readily manipulated by comparatively unskilled operatives.
The accompanying drawings show the apparatus which we employ for this purpose,Figiire 1 being a side view, Fig. 2 a plan, and Fig. 3 a transverse section on Z Z.
On a bed, A, like that of an-ordinary lathe, we fit two head-stocks, B and 0, one of which, B, may be fixed, and the other, C, capable of being slid to and fro by a rack and pinion worked by a handle, D. In bearings in each of the head-stocks is fitted a tubular mandrel, E and F, of which E is driven by a belt or otherwise, and F by gearing from E, so as to revolve at the same speed. The gearing for this purpose consists of a pinion, e, driven from a wheel on E,a horizontal spindle, G,
and on it another pinion, f, driving a wheel on F. The pinion f is fitted with a key or feather on the spindle Gr, .so that it must revolve with it, but may slide freely along it with the headstock 0. At the end of each head-stock is fixed a tube, H and K, closed at their outer ends, but communicating freely with the respective tubular mandrels, and to each of the tubes H and K there is a communication bya flexible tube, hand It, from a reservoir of compressed air, each of those communications being provided with a cock or valve, so that the operator can open or close it at pleasure. Between the two head-stocks B and G is fitted a slide, M, that can be moved along the bed by a rack and pinion worked by ahandle, N. On
this slide is fitted a transverse slide, O,-'carrying a blow-pipe, P, which may be double, as shown, supplied with gas and air by flexible pipes 19, each pipe being provided with a cook or valve, so that the quantity-of air and gas canbe'regulated by the operator. The blowpipe P is fitted to turn on a vertical axis on the slide 0, so that the flames can be directed 011 the glass at any desired angle. Each of the mandrels E and F has at its front end a chuck, R and S, which is lined internally with soft or elastic packing material-such as leather, felt,or caoutchouc-capable of clampinga glass tube without unequal strain, and at the same time preventing escape of air from the hollow mandrel.
The apparatus is worked in the following manner: A glass rod or tube, T, is inserted into and clamped in the two chucks R and S and caused to revolve. The blow-pipe flame .is directed on any part of it, and the part thus heated can be drawn out thinner or set up thicker by moving the head-stock G away from or toward B. By admitting air under pressure into either or both the tubes H K the glass tube can be blown at the heated part into a bulb, which can be elongated or flattened by moving the head-stock 0. Again, if it be de- Having thus described the nature of our invention and the best means we know of carrying it into practical effect, we claim 7 1.
