.FORGING APPARATUS.

SPEGIFIOATIONforming part of Letters Pe t No. 74734.9, dated DeceI'nber 22, 1903.

' Application filed April 23, 1902.;

To all whom it may concern.-

Apparatus, of which improvements the following is a specification.

' The invention described herein relates to certain improvements in mechanism for forg ing car-axles, &c., and has for its object a construction and arrangement of parts where by the article being forged may be turned axially from time .to time and shifted from one shaping-matrix to another as the forging proceeds.

The invention is hereinafter more fully described'and claimed. g Y

In the accompanying drawings, forming a part of this specification, Figure'l is a view in elevation of my improved mechanism. Fig. 2 is a plan view of the same, the upper forgingdie and its operating mechanism being removed. Fig. 3 is a view, partly in section and partly in elevation, showing the forging-dies and the shifting and turning mechanism. Fig. 4. is a sectional view, on a large scale, of the valve mechanism controlling the shifting and. turning devices. Fig. 5 is a sectional view on aplane indicated by the line V V, Fig. 4.. Fig. 6 is a sectional detail view showing the forming-matrices, the plane of secplane indicated by the line VII VII, Fig. 8.

Fig. 8 is a sectional detail view of the shifting carriage with a portion of the cylinder secured thereto, the plane of section coinciding with the axis of the' cylinder. Figs. 9, 10, and 11 are detail views of the turningstem and its operating parts. Figs. 12 and 13illustrate portions of the turning'devices in different positions.

In the practice of my invention one-half of the matrices employed for shaping the axle or other article are formed in a die-block 1,

which issecured on a suitable anvil-block 2.

The other portions of the matrices are formed in a block 3, secured to the movable head 4 of the steam-hammer or other suitable operating mechanism. These matrices are pref- Serial No. 104,253. (No model.)

erablyarranged in accordance with the successive operations on the axle, so that the axle may be shifted without reversal of its movement from one matrix to the other or others. On opposite sides of the anvil-block are arranged suitable stands or frames 5, provided with guides 6 for carriages 7, adapted to be shifted along the stands by means of fluid-pressure cylinders 8, so as to carry the axle or other article from one shaping-matrix to the other, as hereinafter described. Fluidpres'surecylinders9'are secured to the car riag'esf7, with their-"axes parallel with the axes of the matrices in which the axles are to be shaped. The piston-rods 10 of these cylinders are secured to slidingblocks 11, adapted to move along guides 12, formed on the carriages 7 and in line vertically with the axes of the cylinders. Bearings 13 are secured to the carriages 7 on the side opposite the pistons,and in these hearings are mounted rotating heads 14, through which pass stems 15, having their outer ends secured to the sliding blocks 11 with freedom of rotation. The rotating heads the axles or other article to one side of the axes of such article, so that when the stems 15 are rotated, as hereinafter described, an axial rotation of the axle or other article will be effected, so as to present new surfaces to the walls of the shaping-matrices. In order to heads 14 are provided with curved arms l8,and fingers 19 are pivotally connected to brackets 20, secured to the upper or'movable die-block 3. The operation of theseparts to efiect a rotation of the stem 15 and the article being forged is clearly illustrated in Figs. 12 and 13. As therein shown, th'e'finge'rs 19 will as the upper die-block descends strike against .the arms 18 and be turned on their pivotal points until they have passed below the arms, when the fingers will resume or drop to normal or horizontal position below the arms 18, as shown in the lower view in Fig.12 and 9 1 effect the rotation" of the stem and axles, the

the upper view in Fig. 13. As the die-block 3 moves up the fingers 19 will catch under the arms 18 and lift them, thereby turning the heads 14.- and the stems 15 through any desired length of are, and as the die-block reaches the upper limit of its movement the fingers will pass off from the arms, so as to permit the arms and heads to rotate back again to normal position so soon as the studs or pins 17 are withdrawn from engagement with the axle or other article.

It is necessary in order to shift the axle from one matrix to another that the axle should be lifted clear of the matrix in the lower die-block previous to any material lateral movement. To this end the guides'6 are provided with curved grooves 21, into which project pins 22, secured to the buggy 7 and preferably provided with antifrictionrollers. These grooves are so shaped that when the carriage 7 is shifted by fluid-pressure in the cylinders 8 its initial movement will be vertical, so as to lift the axle from the matrix, it being understood that the studs 17 on the stems 15 are in engagement with the ends of the axle. After this initial vertical movement of the carriage it is moved horizontally to bring the axle in position over the next matrix, whereupon the carriage will drop, so as to allow the axle to enter into the next matrix.

In operating my improved mechanism a heated blank is placed in one of the matrices, as a, in the lower die-block and the upper die-block caused to descend to shape the blank, and after one, two, or more shapingblows of the upper die-block the stems 15 on the buggy 7, which has been previously adjusted to bring the stemsinto alinement with the matrix a, are forced inwardly, so that the studs or pins 17 will engage the ends of the blank. After this engagement of the studs with the axle each upward movement of the upper die-block will impart a partial rotation to the stems 15 and the blank carried thereby, so that on each stroke of the upper die a new portion of the blank will he presented for reduction. v\Vhile the stems are forced inwardly, so that the studs or projection 17 are. in engagement with the blank, the friction of the parts will prevent any rotation of the stems and axle by the weight of the arms 18 on the rotating head. Hence if it is desired that the blank should be rotated after each stroke the valve mechanism 23, controlling the flow of fluid-pressure to the cylinders 9, should be operated so that the stems 15. will be withdrawn as the upper die-block descends. By this withdrawal of the stems 15 the heads 1-1 and the stems can be rotated back by the weight of the arms 18, so that on the next upstroke of the upper die-block the heads and stems can be rotated; but before such upstroke of the upper die-block the stems should be forced inwardly by the proper manipulation of the valve mechanism 23, so as to cause the projection 17 to engage the ends of the axle. After the desired red uction has been effected in any one of the matrices the stems 15 are forced inwardly, so as to engage the axles, and the carriage 7is then shifted along its guideways by properly shifting the valve mechanism 24 so as to shift the partiallyformed axle from one matrix to the other.

It will be seen by reference to Fig. 2 that brackets 20, carryingthe turning-pins19, correspond in number to the matrices employed, so that the turning of the article, as is necessary to avoid finning, may be effected while being operated on or shaped in each matrix. It is preferred to withdraw the stems 15 before each blow of the upper die-block in order to avoid any injury to such shifting and turning mechanism.
