Specicaton of Letters Patent.

Patented Feb. 19, 1907.

Application filed June 22.1906. Serial No. 322.941.

To all when it may concern:

Be it known that I, CLARENCE L. TAYLOR, of Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Beam-Straightening 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 1o make and use the same.

My invention relates to an improvement in beam-strai htening resses, the object being4 to provi e a macliine of this character comprising a relatively fixed ram and a re f5 ci rocating ram, with means whereby the re atively fixed ram may be adjusted with relation to the reciprocating ram.

A further object is to provide each ram witha movable die, combined with devices zo whereby when one die is moved to an operative position the other will be moved to an inoperative position.

The invention consists in the parts and combinations of parts, as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in vertical longitudinal section of my improved machine. Fig. 2 is a view in horizontal section. Fig. 3 is a view in transverse 3o vertical section between the rams. Fig. 4 is a view in rear end elevation, and Fig. 5 is a view in section through the cylinder rackbar and shaft for rotating the pivoted die.

1 represents a base-frame, and 2 an up- 3, 5 right frame secured to the base-frame at the rear end of the latter. Mounted in the up right frame 2 are the two shafts 4 and 5, located transversely of the machine in the same vertical plane. The lower shaft 4 is 4o provided at one end with a pinion 6, which is 1n mesh with smaller pinion 7 on shaft 8, driven by a motor 9, and suitable caring. This shaft 8 also carries the fly-whee 10.

Shaft 4 is provided on its end farthest removed from the pinion 6 with the pinion 11, which meshes with pinion 12 on shaft 5, thus causing the two shafts to rotate in unison. Each shaft is provided with two eccentrics, and a /pitman 13 is mounted on each eccentric. he four pitmen thus mounted are pivotally connected to the rear face of the reciprocating ram' 14, which is mounted to move back and forth on the bed-plate 1, the latter being provided with guideways in which the ram moves. The adjustable ram 15 is also mounted to move in the guideways on base 1 and is provided near its four corners with internallythreaded sleeves 16, which latter project inwardly toward the ram 14 and are engaged by the four screws 17, which latter pass rearwardly through the u right frame 2 and carry the toothed whee s 18, each of which meshes with thelarger wheel journaled to the shaft 20, mounted in upright frame 2. One of the wheels 18 is engaged by a smaller wheel 21, secured on shaft 22, journaled in bearings secured to the top of frame 2. This shaft 22 carries a pulley 23, which is driven by a belt 24, actuated by the motor 25. By rotating the shaft 22 in one direction the four screws 17 will be turned in a direction to move ram 15 away from ram 14, and a reverse movement oftheshaft will rotate the screws in a direction to move ram 15 toward ram 14, lengthwise movement of the shafts being prevented in one direction by the pinions 18 bearing against the rear face of frame 2 and in the other direction by the collars 26 on the screws bearing against the upright partition 27. The ram 14 is moved a predetermined distance toward and away from die 15 at each stroke of the eccentrics, and by means of the screws the ram 15 can be adjusted toward and away from ram 14 and set for any depth or thickness of beam.

Each ram is vertically concaved, as at 28, at the center of its inner or working face for the reception of the dies 29. These dies are each journalcd at its ends in bearings in its respective ram, and each is constructed with a rear face curved in the arc of a circle and hearing directly against its ram and with a ribshaped outer face, which bears against the beam being straightened. Each ram 14 and 15 is also provided on its inner or working face and on opposite sides of its die with one or a series of ribs 30.

The die of each ram is provided near its lower end with a miter-gear 31, which meshes with a similar ear 32 on sleeve 33, while the die of the adjustable ram is provided near its lower end with a miter 34, which meshes with a miter 35, fast on sleeve 36. The sleeves 33 and 36 are connected with the rams 14 and 15, so as to move therewith and are both mounted on the shaft 37, lon which they are free to slide. This shaft is l solidly mounted at its front end in the bear- IOO ing 38 and is provided with a pinion 39 fixed thereto adjacent to said bearing.

Meshing with pinion 39 is the rack 40, which latter is actuated positively in both directions by the double plunger 41 in cylinders 42, the rack 40 being pivotally connected to the pitnian 43, which latter is connected to the plunger intermediate the cylinder 42.` The dies being thus coupled up to the shaft io 37 are turned or partly rotated in unison and are so arranged that when one die is turned to present its rib outwardly beyond the fixed ribs on its ram, as shown in Fig. 2, the other -idie will Lbe turned out of action. If straight- 15 ening` is required on the otherside of beam,

i the-direction of movement oi the rack is reversed; thus turning both dies and bringing into action the one that was formerly inactive. The sleeves 33 and 36 are free to slide zol `on shaft 37, thus permitting the latter to actuate the dies irrespective of the position of either or both rams.

44 `are rollers extending longitudinally of i the `machine and through the rams and form 2 5 supports on which the,` beams rest while in i the machine. These rolls are actuated i through the gears 45 and 46 and the shaft 47 which latter is actuated in ,unison with a ,roller-table (not shown) placed on each side 3o of the beam-straightener.

`In, the operation of this machine the adi justable ramf` 15 should be first adjusted to- `ward or ,away from rami 14. This adjust- ,'ment may be made after or `before the beam. 35` ihas been run into osition between the rams. Alter thei rams aveil thus been adjusted power applied to the movable ram, through 1 theeccentric shafts 4 and 5 forces the moveable ram toward the adjustable ram and the 4o ,die bearing at one side against the beam in a yiplane `between the fixed ribs of the other ram operates to straighten out the beam.

It is evident that many slight changes @might be resorted to in the relative arrange- `1,5rnent of parts shown and described-without ldeparting from the spirit and scope of myinvention. i Hence I` would have it understood that I do not wish to confine myself to the -exact construction of parts shown and described; but,

Having fully described myinvention, what I claim vas new, and desire to secure by Letters Patent, is-
