JOHN DAVID KEITH AND WALTER EDGAR FAULKN ER, OF. SANTA ANNA, TEXAS.

COLD-IRON STHAIGHTENER.

Specification of Letters Patent.

Patented May 14, 1907.

Application filed January 23, 1907. Serial No. 353.708.

To all whmn it may concern.-

Be it known that we, JonN DAVID KEITH and WALTER EDGAR FAULKNER, citizens of the United States, residing at Santa Anna, in the county of Coleman and State of Texas, have invented a new and useful ColdIron Straightener, of which the following is a specification.

This invention relates to a straightening device of that type in which a draft hook and a relatively stationary hook are arranged on the body of the device with an adjustable arm mounted on the body so that wagon axles, shafts, pipes, and similar objects, can be straightened or bent, as desired, Without having to be removed from their supports.

The invention has for one of its objects to simplify and improve the construction and operation of devices of this character so as to be comparatively easy and inexpensive to manufacture, readily manipulated, and capable of producing a powerful bending effect.

A further object of the invention is the provision of a device of the character described in whichindependently adjustable and interchangeable members are employed, whereby the device can be employed for straightening a shaft, or the like, when bent to either side of its normal position.

- A further object of the invention is the em ployment of a draft hook which is adapted to e actuated longitudinally in either direction so as to restore ashaft, axle, pipe, or the like,

to its normal position.

With these objects in view, and others, as will appear as the nature of the invention is better understood, the invention comprises the various novel features of construction and arrangement of parts, to be more fully described hereinafter, and set forth with particularity in the claims appended hereto.

In the accompanying drawing, which illustrates one of the embodiments of the invention, Figure 1 is a perspective view of the device showing one manner in which it can be operated. Fig. 2 is a front view showing a different manner of operation of the device.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

Referring to the drawing, 1 desi nates the bar-shaped body of the device, whic is of sub stantially the same cross section throughout its length, except atone end where an eye 2 bar from which the body is made. Extend' ing freely through the eye 2 is the threaded shank 3 of the draft hook 4. The shank 3 is of any desired length and engaging the thread thereof is a lever nut 5 and an ordinary wrench nut or bur 6, the latter being arranged on the under side of the body and the lever nut on the upper side. At the root of the hook 4 is formed a transverse shoulder or abutment 7 on which the article to be straightened is adapted to rest according to one method of using the device. On the body 1 is slidably mounted the fulcrum or arm 8 and the relatively stationary hook 9. This hook 9 and arm 8 are freely slidable longitudinally of the body 1 and are removable therefrom so that their positions may be reversed. The arm and hook are each provided with an angular opening 10 through which the body 1 extends.

In operating the device, in accordance with the method shown in Fig. 1, the arm 8 occupies a position between the two hooks of the device, and the lever nut 5 is employed for actuating the draft hook. The object to be straightened may be a pipe, shaft, axle, piece of bar metal, or the like. The object designated by 11 is engaged by the hookst and 9, and the arm 8 is then adjusted to the proper position for producing the desired bending effect. In case the arm is not long enou h to bear upon the object, a block of meta 12 may be inserted between its free end and the object, as shown. With the parts in this position, the draft hook 4 is ready for operation. The lever nut 5 is then turned in such a direction as to draw the hook 4 toward the body 1, the said nut 5 bearing against the top surface of the body at the eye 2. The arm 8 thus acts as a fulcrum on which the object is bent, while the hook 9 serves to steady the object. Before the nut 5 is operated, it is necessary to run the nut 6 back toward the hook 4 so as not to interfere with the movement of the latter by the turning of the nut 5.

In case it is desired to bend the object 11 in the direction opposite from that already described, the arm 8 and hook 9 are removed from the body 1 and returned thereto in reverse order, as shown in Fig. 2. The device is then adjusted to the object 1.1 so that the latter bears against the abutment 7. After the nut 5 is run back the desired distance, the nut 6 is turned so that the hook t is moved away from the body, the said nut 6 bearing against the underside of the eye 2. By thus operating the nut 6, the object 11 is bent back to its normal position about the hook 9 as a fulcrum. The advantage in having the arm 8 and hook 9 interchangeable is that pipes, shafting, and the like, that are located in close quarters, can be straightened by either of the methods described, while the device as a whole occupies the same position. As, for instance, where a pipe is located in the corner of a room, the same can be bent from one side or the other with equal facility by means of the present device.

From the fore oing description, taken in connection with t e accompanying drawing,

the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and, while we have described the principle of operation of the invention, togetherwith the apparatus which we now consider to be the best embodiment thereof, we desire to have it understood that the ap paratusshown is merely illustrative, and that various changes may be made, when desired, as are within the scope of theclaims.

What is claimed is 2- 1. In a metal straightener, the combination with a beam or body portion composed of a strip of flat metal bent centrally on itself to form an'eye at one end of the beam and having its arms doubled and engaging one another'throughout their length to form a guidin portion having an angular cross section 0 uniform dimensions, of a screw extending through said eye and having a hook thereon to engage the work, and means co 0 erating therewith and engaging the opposite edges of the beam for operating the screw axially in both directions, and a fulcrum arm and a resistance hook having angular openings therein of equal dimensions to inter changeably receive the beveled arm of the beam and to permit disengagement and interchanging of the fulcrum arm and hook by a relatively longitudinal movement thereof.

2. In a device of the character described, the combination with a beam or body portion having an angular cross section toward one end and an eye formed at the other end, of a screw fitted to operate in said eye and provided with suitable actuating means for moving it axially in two directions, a hook rigidly fixed to said screw having a transverse abutment thereon adapted to cooperate with the work when the screw is being actuated in one direction, and having a curved portion opposite to said abutment to cooperate with the work when the screw is being operated in the opposite direction, and interchangeable fulcrum and resistance devices guided on the beam and adapted to be arranged in reversed order when said screw is operated in opposite directions.

In testimony that we claim the foregoing as our own, we have hereto affixed our signatures in the presence of two witnesses.
