WILLIAM HENRY MORGAN, 0F ALLIANCE, OHIO.

FORGING, FLANGING', AND OTHER PRESS.

Application filed February 25, 1918.

To all whom t may concern:

Be it known that I, WILLIAM HENRY MORGAN, a citizen of the United States, and a resident of Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Forging, Flanging, and other Presses; and I do hereby declare the following to be a full, clear and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates toY improvements in forging, flanging and other presses.

Heretofore presses designed for heavy work, have been operated by hydraulic mechanism which is complicated in construction, and requires constant attention, frequent repairs and adjustment of parts in order to keep them in proper working condition.

The object of this invention is to simplify and consequently cheapen the cost of construction and upkeep, by dispensing with the hydraulic devices, and actuating the movable platen both in its initial and final or power strokes, by mechanical devices actuated by a motor or motors, preferably electric motors.

With these objects in view my invention consists in the parts and combinations of parts as will be more fully explained and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view partly in side elevation and partly in section of my improved press and Fig. 2 is a similar view at right angles to Fig. 1.

I have illustrated the improvement applied to a forging press, but it isy equally adapted for flanging, bending and other presses, hence the improvement is not confined in its application to any particular kind of press, but is applicable to all apparatus of the several types above referred to.

The base or lower Xed platen 5 of the press rests upon the shoes 6, which are similar tothe shoes commonly used' in mills for supporting heavy machiner and carries the die or other tool 7. This base or platen is located over the well 8, andfis provided with a series of openings for the sleeves 10, four in the present instance, which are rigid with the movable base member 11, and move with the same. The lower movable base member Specification of Letters Patent.

carries the four cylindrical columns 12 secured at their upper ends the upper movable platen 13 provided with the diel or other suitable tool 14. This upper platen is carried and supported by the columns 12, and the latter pass through the sleeves 10 on the lower movable base member 11 andare screw threaded as at 15, at their lower ends.

The lower movable base member 11 is hollow and carries four worm wheels 16, each of which has an integral nut 17, meshing with the threads 15 on the columns 12, the worm wheels being seated on the lower member 18 of the movable base member, and the nuts mounted in the sleeves 19 dependingk from said lower member. The four worm wheels 16 mesh with the worm shaft 20 mounted in the movable base member, and the said shaft is preferably driven by an electric motor connected thereto by a. universal coupling.

Mounted in bearings 21 in the vbase or fixed platen 5 is the shaft 22, carrying gear wheel 23 which is geared up to any suitable motor. Shaft 22 is provided with two cranks or eccentrics 24 (eccentrics being shown) upon which the movable base mem-' ber 11 and all the parts carried thereby, are supported by the yokes 25, which are integral with or rigidly secured to the said movable base member and embrace the eccentrics 24 as shown. Bearings or bushings 26 are interposed between the yokes 25 and the eccentrics 24 at the top, and pitmen 27 are interposed between the eccentrics and the bearings 28 carried by the lower movable base member immediately below the Veccentrics. Bearings or bushing 26 have a sliding contact with the underside of the yokes 25, and the pitmen 27 have rocking contact on the bearings 28, so that as the eccentrics revolve, the bushings 26 and pitmen 27 rock laterally and impart an upwardV or downward movement to the movable base member 11 and parts carried thereby, the direction of such movement being dependent of course on the direction of movement of the eccentrics. The pitmen 27 and bushings 26 are cut away at the" side as shown in Fig. 2, to permit of the necessary rocking movement of these parts without contacting with -the columns 12 between which theyV are located.

The bearings 2S which carry lthe Vpitmen 27 are sup orted on the wedge blocks 2Q, which are eld'in position and adjusted by the screw rods 30 and nuts 3l, the rods 30 being anchored to the cross member 32which is a part of the movable base member and is located between the'lower ends of the pitmen 27 and operates to hold the latter against inward displacement.

The yokes 25 above referred to are integral or rigid with the sleeves 10, and support the movable base member 11 and the parts carried thereby directly on the eccentrics of the shaft 2Q, and the sleeves 10 are mounted in the base of fixed platen 5, and are adujsted and held in proper relative position by the wedges 33 which are secured in place by the screw bolts 34, the said wedges being located at the upper and lower margins of the base so as to aHord extended bearings for the sleeves.

With the construction as above described,

by rotating worm shaft 20 in one direction, the four worm wheels 16 and their nuts 17, will be rotated in a direction to elevate the four columns 12, the upper platen 13 and the die or other tool 1-1', and by reversing the direction of rotation of the said shaft 20, the columns and upper platen and its die will descend, the movable base member 11 being suspended from the crank shaft- 22. In the operation of the device, the upper die or too-l 14;, will be lowered onto the work, and apply the initial forging or bending pressure to the work on the die or other tool 7, by rotating the worm wheels through shaft 20, and after the upper die has applied this initial pressure to the work, the ower or working stroke of the upper die 141.` is accomplished by rotating the shaft 22, whichacting through the pitmen 27, forces the movable base member 11 and all the pants carried thereby downwardly a distance equal to the throw of the eccentri'cs, or as much of said distance as the character of the work will permit. If for instance in bending plates, the eccentrics make a complete revolution, the upper platen can be again lowered onto `the work by the worm, and a second power or working stroke applied through the eccentrios, and this operation can be repeated as many times as may be necessary to complete the work. After the work has been forged, bent or otherwise acted upon, the upper platen is elevated by rotating the worm shaft 20 in a direction to elevate the columns 12. YIn making the power stroke, all parts of the press except the base or Hxed platen 5, move downwardly, whereas in the initial stroke, the columns 12 move down through the base 5 and movablebase member 11, which latter Yis then suspended from the shaft 22.

While I have shown and referred to the shaft 22 as provided with eccentrics, it is evident that it may have cranks hence I would have it understood that the term eccentric is intended to include cranks or their equivalent. It is also evident that other changes might be resorted to without departing from my invention, hence I would have it understood that I do not confine myself to the construction or details shown but consider myself at liberty to make such changes as may come within the spiritl of the invention and scope of the claims.
