IMPROVEMENT iNMACi-HNES Foa FLANGINGBolLER-HEADS.
Specification forminghpart of Letters Patento. 173,SOS, dated February 22, 1876; `application tiled septembepet, 1875.
To all whom it may concern;
Be it known that l, RICHARD- O. N oGrnN'r, of Dayton, iii the county of Montgomery and VState of Ohio, have invented certain new and useful Improvements in Machines for Nozzlin g Fine-Holes in Boiler-Heads, and I do hereby declare that the following` is a full, clear, and exact description thereof, which vwill enable others skilled int-he art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification, in which n Figure l is a side elevation of the machine. Fig. 2 is a sectional view of a portion of the operating devices.
The object of my invention is to procure a machine for forming nozzles on boiler-heads or plates of metal, to which iiues are attached in the usual way, in a simple and rapid inanner without subjecting the heads to the liability of strains and flaws, as is the casein most methods now in use for. this purpose;
The improvements consist in the novel combination `and arrangement ot' a peculiarly-constructed vertical rotary shaft carrying the` formin g-tool--an essential element of my invention-With the necessary operating mechanism therefor, the frame-work, and an adjustable clamp for holding the head or plate to be operated on in position, as will be herewith described, and the invention distinctly pointed out in the claims.
Corresponding letters of reference indicate like parts in both iigures.
A suitable frame-work, A A, of anydesired shape and proportions, upholds a platform, B, and two bearing-beams, C and D, which are securely attached to the sides ot' the frame,
and have journal-bearings in which the journals ofthe beveled-gear wheels E and F revolve, as represented by the dotted lines a, Fig. 1. G and H are two bearings, in which the shafts I and J are confined. These shafts are provided on their outer ends Vwith gear- Wheels K and L engaging with veach other, and the fast and loose driving-pulleys M.v -Their inner ends are provided with the beveled-gear Wheels N and O, which engage with the Wheels E and F. P represents a hollow the machine to different-sized work.

screw-shaft, whichengages with a'thread cut A in `thewheel E, and hywhich it is raised up `or down, a spline and groove in the vjournalbearing R preventing it from turning. Fitting snugly, but free to revolve, in the screw-shaft P is a solid shaft, S, which passes through the center ofthe wheel F, from which it receives rotary motion by means of a spline and groove in the usual manner. The top of this shaft is a head, T, having shoulders resting on the top of the screw-shaft l?, and at the bottom of the screw-shaft is-.a collar, mi, upon the shaft S, against which the screW-shaft-acts to lower the forming-tool: The head T has. al square socket, in which. the forming-tool U is held. The platform B has a circular opening through it, just over the lshaft S, and in this openingis the disk V, having a central orifice just large enough to let the tool U pass through. To each machine belong several disks differing only in the sizes of the central orifices, and which are interchangeable for accommodating W is a top brace connecting the frames A, and having a central threaded hole, through which a screw, X, works. To the bottom ot' this screw is attached a bell-shaped clamp, consisting of a bottom annulus, b, of a diameter greater greater than that ot' the tool, supported by The screw carrying the clamp is worked by means of the hand-wheel Y. The forming-tool U is composed of ashank, d, fitting in the socket of the head T, and easily removed, and of a body of the shape represented, having two parallel disks, e and f, provided with journal-bearin gs, in which the equidistant rollers g, of which there may be four the lower one, in order that the rollers may be more or less inclined.
It is my purpose to have with each machine several forming-tools, each fitting in the same head, and differing only in proportions according to the character ot' the work required.
The operation of the machine is as follows: The heated plate or boiler-head, having had circular oriflces lnade as usual, is placed upon the platform with one of the holesdirectly over the forming-tool. The clamp is brought down upon it and holds it Securely in position.
The top disk e is smaller than i Motion is imparted to the machine from the y pulley M, and it will be noticed that the shaft S has a rapid revolution carrying With it the tool U, and `the shaft P has a slow upward motion carrying with it the shaft S and also the tool U, so the tool has a very slow upward, but at the saine time a rapid rotary, motion. The plate being securely clamped, the tool, as it moves upward, presses upon the overlapping edges of the hole to be nozzled, and gradually turns them upward. The rollers upon the tool always keep the enlarged orifice circular. This is continued until the tool has passed through the plate, when the operation is concluded, and a lnozzle or flange will be formed upon the boiler-head. In Fig. 2 this operation is partially represented, k representing the boiler-head with the nozzle partially formed.
H-aving thus fully'described my invention, what I claim as new," and desire to secure by Letters Patent, is`- RICHARD o. NUGENT.
