PHILIP MEDAItT, on ST. LOUIS, MISSOURI, ASSIGNOR OF ONE-HALF T WILLIAM MEDART, or SAME PLACE.
MACHINE FOR STRAlGHTENlNG METAL BARS OR PIPES.
SPECIFICATION forming part of Letters Patent NO. 352,652, dated November 16, 1886.
Application filed Apr-1112, 1886.
To all whom it may concern:
Be it known that I, PHILIP l\IEDAR'l, Of St.
Louis, Missouri, have invented certain new and useful Improvements in Machines for Straightening Metal Bars or Pipes, of which the following is a specification.
The object of my invention is to provide a simple, practical, and efficient machine for the straightening of metal'bars or pipes.
In an application for Letters Patent filed by me January 13, 1886,No. 188,418, I have shown and claimed a machincin which the endwise relation of the shaft being operated upon and the straightening-rolls is varied by the draft crer5 ated by the rotation of the shaft in contact with the -rolls,so that the shaft is operated upon throughout its entire length. In my present invention the shaft is caused to travel both through the straightening rolls and through the shaft carrying and rotating devices by power derived in the same way. This feature of my invention, as well as others, will appear more fully from the following description.
In the accompanying drawings, Figure 1 is a side elevation; Fig. 2, a rear view. of one-of the chucks, showing the driving-gears; Fig. 3, a view of the face or front of a-chuck;Fig. 4, a section on the line 4 4. of Fig. 2, and Fig. 5
a section onthe line 5 5 of Fig. 8.
A is the main frame, about the middle of which is mounted the frame or bed-platc F,
which carries the straightening devices. These devices are. shown as consisting of pairs of 5 straightening-rolls, two such pairs being arranged below and one above the shafting,which is indicated by dotted lines in Fig. 2.' All three pairs of "rollers are mounted in housings f, which maybe rotated about a center to ad:
40 just the rolls relatively to the shafting. The
housing carrying the upper pair of rolls may be vertically adjusted by means of a screw, as'
clearly shown, while the lower, pairs of rolls may be adjusted-toward and from each other 5 by means ofa reversely-threaded screw-bar.
The straightening-frameJor bed-plateF is: mounted upon four vertical screws providedwith-sproeket--wheels, on :which an endless chainrun's. By this means'the frame is raised and lowered to adapt themachine to shafting of differentisizes;
Serial No. 198,560. (No model.)
This part of my invention isidentical in construction with that shown in another application filed by me January 13, 1886, and numbered 188,418, and a more specific description is therefore unnecessary.
The details of construction are obvious and, so far as this invention is concerned, immaterial. On each side of the straightening devices I mount a sheave-chuck, the details of construction of which are fully shown in the drawings, and are presently described. The chuck-head is preferably carried by. a tube or hollow mandrel, upon the rear end of which a gear-wheel, K, is mounted. This gearis driven by a pinion on a counter-shaft provided with an ordinary belt-pulley, as seen clearly in Fig. 1. The chuck-head is provided with four corner plates, 0, between which four radially-movingsheav'e-blocks operated by adj usting-screws 11 work; Each'of said blocks carries a sheave or roller, I, which is preferably formed with a grooved periphery, preferably of the shape shown in the drawings. Their faces or peripheries may also be serrated or roughened, as clearly seen in Fig. 6.
So faras I am aware, I am the first to use a sheave-chuck inthis class of machines. It
will be obvious from the construetionof this chuck that a shaft or bar gripped between the sheaves will be held firmly and caused to rotate with the chuck, and yet be capable of moving 'endwise therein when power is applied for that purpose, the sheaves turning upon their axes and permitting this action.
Theoperation of the machine is as follows: The shal'ting is passed through one of the sheaves X until its end comes between the straightening-rolls, the upper pair of which is screwed down to give the desired pressure, and the sheaves of the chuck X are screwed up. Power being applied to that chuck, the shafting will be positively rotated, and in its rotation in contact with the straightening-rolls a strain or draft will be crcatcd which will draw the shafting through the chuck X and between the straightening-rolls. As its end emerges from the straightening-rolls it will pass betweent-he sheaves of the chuck Y and through the hollow mandrel thereof, which forms a guide and support to the end of the shafting. When the other end of the 'shafting has passed out of the chuck X, the chuck Y- isscrewed up so as to grasp the shutting, and, being driven by power in a suitable direction, the shafting will continue to move between the straightening-rolls. In this way all portions of the shal'ting' will be properly acted upon.
The shaiting may be run back and forth through the machine as often as may be desired, as the workman may apply the power to drive either chuck in either direction.
I claim as my invention- 1. The combination of a sheave-chuck in which the sha'fting to be straightened is secured and by which it is rotated, and the straightening and draft rolls in contact with which the shafting rotates, whereby a draft or strain is created! which causes the shafting to move endwisc through the sheave-chuck and between the straightening-rolls.
2. Thecombination of the straightening and PHILIP MEDART.
