This invention relates to a forging machine operative to automatically heat and sha e metal blanks.
eretofore', inforging ojperations, it has 5 beencustomary to introduce blanks into a furnace by hand, leave them therein for-a time sufiicient in the judgment'of the operator to properly heat them, and then transfer them by hand from said furnace to a l rolling mill, drop hammer, or other shaping device. This practice does not insure even heating of the blanks, or subjection of, the heated blanks to the action of the shaping device always in like condition. The main object of the present invention is the elimination of the human element inthe transition of the blanks from a suitable source of supply, through heating means, and thence to shaping means and to a -finished product,
substituting for the manual operations heretofore employed mechanical operations performed by automatic machinery, thus reducing cost, maintaining uniformity of heating and shaping, and producing better products.
Another object of the invention is the production of a machine wherein a succession of blanks is handled and each blank is sub jected to the same degree of heat for the same length of time as all other blanks.
roduction of a machinewherein the blan s are automatically transferred from a source of supply to heating means, from heating means to shaping means,- or both. With these and other-obinvention consists in certain constructions and combinations which will be hereinafter fully described and then specifically set forth in the claims hereunto appended.
In the' accompanying drawings, which form a part of this specification and in which like characters of referencexindicate the same or like parts, Fig. 1 is a side elevation of a machine constructed in accordanbe 4 with the invention; Fig. 2 is a plan view 'of' the machine shown in Fig. 1; Fig. 3 is a de tail view, taken on the line 3-3 in Fig. 2; Fig. 4 is a sectional viewon an enlarged scale taken on the line 4-4 in Fig. 2; Fig. 5 50. is a cross-sectional view on a smaller scale of the structure shown in Fig. 4; Figs. 6, 7

and 8 are fragmentary and sect-ional'detail views taken respectively on the lines 6-6, 7 -7, and 8-8 in Fig. 5;- and Fig. 9 is a fragmentary sectional detail view on a larger scale of a part of the structure shown in Fig. 5.,
In carrying the invention into effect, d means for heating blanks to be forged, means for shaping the heated blanks, and means for transferring the blanks from the heating means to the shaping means. In the best constructions, there is also provided a source, of blank supply and means for transferring blanks there fromto the heating means. In the best constructions also, the heating means operates to subject a succession of blanks to the same degree of heat for thesamc length of time in order that all the blanks will be in like condition when transferred from the heating means to the shaping means which will operateto progressively shape the heated blanks. The means above referred to may, be widely varied in construction within the 75 scope of the claims, for the particular machine selected to illustrate the invention is but one of many possible concrete embodiments of the same. The invention therefore is not to be restricted to the precise details of. the structure shown and described.
Referring to the drawings, 10 indicates a foundation upon which the units constituting the machine are mounted. There is provi-ded means for heating the blanks toibe forged; and while this means may be otl'i'erwise constructed, as shown it includes ai-cy-- lindrical furnace 11. having a heat resisting lining 12 of wellknown character. The furnace 11 is supported in elevated position by 10. The interior of the furnace is heated by gas entering the same. tangentially through gas nozzles 14-14, the flow of gas through these nozzles being controlled by means of valves 15 of well known construction, The gas enters the furnace through the nozzles v14 under pressure, and a swirling movement of the gas is produced in the furnace as it burns so that all parts of the furnace are-heated' to the same degree of temperature. p
A device adapted to be used for removing a Wheel from an axle upon Which it is keyed comprising a body provided at its opposite ends With alined sockets of different sizes, and anvil plugs fitting in the sockets.

nism'just described, a succession of blanks is transferred from the feed table 58 to the blank holders 18 as they successively come into position to receive the blanks.
Means are also provided for ejecting heat- While this shown, it includes a second plunger 66 which is longer than the plunger and which works through the donble-ba rreled member 28 and the single-barreled member 29 in the walls of the furnace, moving through the blank holder 18 which at the moment is in line with said members, and by'its forward movement therethrough ejecting "a heated blank from one blank holder 18 ,while the plunger 60 is loading a fresh blank into the adjacent blank holder 18, as clearly shown in Fig. 6. The rear end of the plunger 66 is secured to the crosshead '61 before referred to, and therefore move-' blanks from the furnace and, further, is a part of means for transferring heated blanks from the blank heating means to shaping means. This transferring means further includes a chute 67 into which a heated blank drops when ejected from the furnace, and down which it slide: to blank shaping means. While other shapin means may be employed, as'shown, a ro mg mill 68 of well known construction is used' for progressively shaping the heated blanks. The rolls'of this mill are indicated by the dotted lines 69 and 70, which are co-incident with the pitch lines of a pair of superpo.'ed gears 71 which drive the shaping rolls in the usual manner. The lowermost roll is mounted on a shaft 72 which is driven by means of a gear 7 3 operated by a train of reducing gearin of the usuaLtype and generally. in-
dicated by the reference character 74. Outside the gear. 73, the shaft 72 carries a bevel gear 75 which is in mesh with another bevel gear 7 6 fast on the shaft 56 before referred to. By means of the intergeared relation of v the rolling mill and of the mechanism for transferring the blanks, each part of the machine operates in timed relation with each other part. When the heated blank is to be shaped into a knife blade, for example,
the rolls of the rolling mill are in the form of circular dies, and in such case'it is necessary thatthe heated blank enter the bight of the mill rolls. at the proper instant. To insure this, there is provided a plunger 77. the forward end of which works throughsia boss 78 formed on the bottom end' of the chute 67. This plunger operates to push a '1 blank which has slid down the chute 67 into the bight of the mill rolls at the proper time. The rear end of the plunger 77 is secured in a head 78 connected by means of a-link 79 to an arm 80 which is integral with the hub or fulcrum boss of the cam arm 44 before referred to. The plunger 77 therefore dey rives its movement from the cam 49 which also controls the movement of the ratchet anechaninn for intermittently rotating the blank is subjected to t e same degree of heat for the same len hof time and wherefrom the heated blan s are succeisively transferrecl to the rolling mill which progressively shapes them into the desired article in accordance with the contour of the mill roll die':. And in view of the foregoing, a detailed description of the operation of the device is deemed unnecessary toa full understanding of the invention, and is therefore omitted in the interest of brevity.
