ronerive MACHINE.

Application filed December 31, 1917. Serial No. 209,793.

To aZZ whom it may concern:

Be it known that I, WADE H. IVINEMAN, a citizen of the United States, residing at Chicago, in the county of Cook and State oflllinois, have invented certain new and useful Improvements in Forging Machines, of which the following is a full, clear and exact specification.

My invention relates to forging machines.

the anvil of a forging machine to its supporting frame by means of shims or the like, and, in certain instances, to provide between the anvil of a forging machine and the frame thereof, an intermediate base block which is in turn attached to the frame by means of shims. These constructions have, however, decided objections arising from the fact that the wear between the partsconstantly tends to loosen the shims. Moreover, these objections are especially apparent when shims are used in connection with forging machines of the drill sharpener type, as in such machines it is desirable to utilize a large and expensive casting for themain frame of themachine, and repeated driving and re-driving of the shims as wear takes place often results in such mutilation replaced.

' My invention has for its object to provide an improved means whereby the anvil of a forging machine may beattached to its supporting frame and held in rigid relation 3 thereto despite wear between the parts. A

further object of my invention is to pro-' VldG an improved wear absorbing means for fastening the base block of a forging machine to the frame-thereof in such a manner that all necessity for scarring or otherwise mutilating the frame by the driving of shims or the like between the base block and the frame is entirely overcome, my improved mechanism acting automatically to take up wear as it occur. These and other objects and advantages of my improved construction will, however, hereinafter more fully appear.

n the accompanying drawings, I have shown for purposes of illustration one emodimen't which my invention may. assume in- It has heretofore been proposed to attach of the casting as to require the same to be practice, illustrating the same as applied to use in connection with a standard form'of drill forming and sharpening machine.

In these drawings,-

Fig. 1 is an end elevation of such a machineequipped with my improvement.

Fig. 2 is a detail View taken substantially 011 line 22 of Fig. 1.

Fig. 3 isa detail view on line 33 of Fig. 2.

In this illustrative construction, it will be noted that I have shown a forging machine of the well known Sullivan type including a cast base frame 1 having a standard 2 thereon on which is carried a percussive motor 3' adapted to reciprocate an taken substantially upper swaging die 4 into and out of 611 gagement with a lower stationary swaging die or anvil 5 supported on the frame 1, the operation of the motor being controlled through a suitable controlling mechanism 6, which is in a foot lever 7. As usual in this type of ma chine, suitable cooperating upsetting mechanism is provided which is adapted to be controlled by a controlling lever 8, but as this mechanlsm does not enter into the present invention a detail description of the same is believed to be unnecessary.

In my improved construction it will be noted that the lower swaging die 5 rests upon a base block 9, and that this die 5 is provided with a depending dove-tailed portion 10 on its lower surface adapted to be received in a corresponding aperture in the upper surface of the base-block and tobe held rigidly in position in that aperture by suitable means, of a. shim 11. As illustrated, this base block 9 is disposed in a suitable aperture or seat 12 formed in the frame 1. The base block 9, as shown herein, is also provided at each of its opposite ends with communicating slots 13 andholes 14 adapted respectively to receive the heads and shanks of a plurality of vertically disposed bolts 15 which extend down through'these apertures and corresponding apertures 16 in the frame 1., into a large lower aperture 17 in the latter, in turn accessible through an opening 18 in the front of the'frame; Here, it will turn controlled by herein shown in the form be noted that each of these bolts carries on its lower end a coiled spring 19 disposed between a plurality of washers 20 thereon, one of which is pressed against the upper surface of the aperture 17, while the other engages an adjustable nut 21 accessible through the aperture 18.

In this improved construction, it will be noted that the members Band 9, taken together, anvil, and it will be observed that no matter what wear may take place between the base block 9 and the frame 1, this wear as it occurs will be automatically taken up by the springs 19, which constantly tend to force the base block against the bottom surface of.

the aperture 12 on the frame. It will also be noted that bolts 15 at opposite sides of the center line of the block 9, the latter is acted upon by the springs 19 in such a manner as to hold. it very securely in position. As a result of my improved construction, it will be observed that all necessity for driving any shims or wedges between the block 9 and the 7 frame 1 is entirely eliminated. It will also be. noted that the lower die 5 may be readily attached to the base block by any desired means, such as the shim 11, without any danger of mutilation, sinee the base block may be, and preferably is, formed ofsteel, and. is

, therefore less susceptible to damage than the cast frame. Obviously here also, should the block be damaged, the same can be readily replaced at a very small fraction of the cost involved in providing a new frame. Attention is here also directed to the fact that i when it is desired toadjust the tension of the springs 19, the same are readily accessible for adjustment through the aperture 18 in the front of the frame. These and other advantages of my improved and simplified,

construction will, however, be clearly apparcut to those skilled in the art. i

While I have in this application specifically described one embodiment which my invention may assume in practice, it will be understood that this form of the same is used for purposes of illustration, and that the invention may be modified and embodied in other forms without departing from its spirit or the scope of the appended claims.
