DENMON G. STONE, QB WAYVARSING, YORK, ASSIGNOR TO JQSEPH. WBIGHT- MAQHINE E03 MA EAWURJNQ AXE Specification of Letters Patent mg' g dated {Lpril e1, 1838.

To all whom it may concern:

Be it known that I, DENMON C. ST NE, of the village of Naponock, in the town of W awarsing, in the county of. Ulster and 'State of New York, blacksmith and machinist, have invented, constructed, made, and applied to use anew and useful improvement in preparing the iron part or r portion of narrow axes, broad axes, hatchets,

and carpenters adzes, and punching and shaping the same by the machinery of a single machine so that they shall be ready for welding the steel upon them when they have undergone the operations of the said machine, which said inventions'is called and known by the name of the axe-machine, and is specified and described in the words following-that is .to say:

This invention or improvementconsists of the combination in a single machine of parts hereinafter specified .as new and of the machinery hereinafter described'for performing the operations, first, of cutting the bars of iron previously rolled and prepared for that purpose into pieces of any desired length, as represented in Figure 2, Plate 1. Secondly, punching the eye of the ax in the said pieces after they have been heated to a red heat in a furnace. Thirdly, driving a steel handle through the eye. so as to. handle the same and preserve the proper shape during the subsequent operations. Fourthly, shaping the ears of the ax in one die, and smoothing and reducing it in a second die. Fifthly, pressing and shaping the ax in another die after the steel has been welded in.

The shears or cutting machinery (No. 1 of drawing) are composed of two levers Nos. 1, and 1, Fig. 1, Plates 1 and 2, fixed in shafts (N0. 2) and are composed of iron or other suitable material, the ends of which project beyond the shafts and being armed with steel 21, 21, Fig. 4, cut the iron bar as it is presented to it in the usual way of cutting bar iron for that purpose.

I do not claim anything as original in this mode of performing that operation.

The levers are worked by eccentric wheels, Fig. 2, Plate 2, oneof which is shown in Fig. 4:, same plate, which are fitted into strong iron rims, No. 22, Figs. 3. and 4:, at their ends, which rims are of such elliptical form that the largest diameter is twice the distance from the center of the shaft on which the eccentric wheel revolves, to that part of the circumference of the wheel farthest from the said center of theshaft, The shafts, No. v2, 2, on. which the said levers are fixed are placed one directly above thefoth er. Each of these shafts is both a fulcrum fol the leverfixed on it and a bed for thedieS.

befo ment n When the iron hasbeen out andproperly heated it is introduced into a chamber (N0. 3) Figs. 1 and 5, Plates 1 and,2,forl ned by a base or stand of cast iron or other suitable material (No. 4) which stand is fixed atthe sides by keys movable at pleasure to reguQ late the size of the chamber according to the size of the ax. The sides of the chamber are formed of pieces of cast iron or ether suitable material fixed permanently in. the

base or stand above mentioned and through an opening of any size that .may be de? sirable in one of those sides, a slide composed of iron or other suitable material enters which is moved into the chamberior the purpose of compressing and holdingthe iron firmly inits place. This is Worked a 80 j which lever as the cam revolvespushes the an o a c m (No 6) n ever (Na.

said slide forward or backward, holding the iron firmly in its place until the punch the far as it is permittedto do. The-backward motion of-the slide then releases it is taken by the workman and inverted for the purpose of presenting the opposite side sliding shaft (No. 8) has penetrated itias as j The punch, Fig. 6, No. 25, Plates 1 and 2,

is formed of steel of proper shape and dimensions for the eye of an ax, hatchet, &c.,'

and is fastened into thesocket of a hollow sliding shaft of iron, No. 8, supported by a stand (No. 18) attached to the main stand 1 v (No. 7) with suitable boxes by oneor more keys. This sliding shaft is fixed into the end of a lever beam (No. 9, 9, 9) which is fixed upon and worked by the shaft through which the upper lever composing the shears passes. After the iron has been thus punched through in this chamber it is placed in a second chamber (No. 10) Fig. 11, under the other end of the lever beam (No. 9, 9, 9). This chamber is of similar construction to the first except that it is closed on both sidesand has no slide. This is for the purpose of driving the steel handle, above mentioned through the eye. This steel handle of proper form and size to corwith keys and may be changed at pleasure;

respond with the punch used in the first chamber, is then forced through the eye of the ax by a sliding shaft (No. 11) supported and worked in the same manner as the sliding shaft (No. 8) at the end of the lever beam as last above mentioned, and the ax is then ready to be introduced into the first of the dies before mentioned.

The two main shafts (No. 2, 2) are armed with dies (No. 12, 12) upon the upper side of the lower and the lower side of the upper shaft, which are fastened in their places The main shafts are fixed in iron stands (No. 17 17) of suitable proportions similar to those used in machines for rolling iron and are worked by the main levers as above mentioned. The first dies (No. 12,12) are of such a form that the ax is pressed so as to bring out the ears of the ax to a'proper shape, Fig. 11, Plate 2, and Fig. 3, Plate 1, by means of the figure given to the dies, and the vibratory mot-ion communicated to the shaft by the main levers as aforesaid. The

ax is then taken out and introduced edgewise into a second set of .dies in the same shaft so as to press the edges into proper shape, Fig. 4, Plate 1, and Fig. 13, Plate 2,

It is'then passed to the third pair of dies in the same shaft where it is'again smoothed down and receives its final shape, Fig. 5, from the figure of the dies andis then ready to be split (as at Fig. 7 in chamber (No.

19) for receiving the steel chisel, Fig. 12, worked similar to'the punching operation. After the steel which may be fitted for that purpose by heating and cutting to shape,

Fig." 3, and pressing in a die of proper form, Fig. 14, has been welded in the ax and hammered to near its proper shape it is then passed into a fourth set of dies,'No. 20,

in the same shaft where it is pressed into its pro-per shape and is then ready for, grinding.

The above described parts of the machine are to rest or be fixed upon a bed plate (No. 13) of cast iron or other suitable material.

The whole machine is to be worked by Water power, steam or any other mechanical power of sufiicient force, which may becom municated to the eccentric wheels, Figs; 2 and 23, Plate 2,-by means of a pinion wheel (No.- lt) cog wheels, &c., with a balance Wheel -(No. 16) to regulate the motions .of the eccentric by a driving pulley, No. 27.
