Specification of Letters latent.
Patented Aug. 12,1913.
Application filed March 6, 1913. Serial No. 752,453.
To all 'wlwm it may concern:
Be it known that I, PHILIP M. HAAS, residing at Youngstown, in the county of Mahoning and State of Ohio, a citizen of the United States, have invented or, discovered certain new and useful Improvements in Straightening-Machines, of which improvement the following is a specification.
In Letters Patent No. 666,419, granted to me January 22, 1901, I have shown and described a machine for straightening .rods or tubes, wherein the blank to be straightened is fed between rolls some of which have their axes angularly disposed with relation to each other, to the end that the blank is given a rotary as well as a progressive movement. There is shown, in the disclosure of this patent, a single pair of adjustable rolls mounted in fixed housings ata point midway of the extent of the machine, such rolls being driven by shafts, and so mounted thereon that their axes may be adjusted with relation to the axes of the shafts. On each side of these rolls there is an undriven single pressure roll the axis of which is ad'ustable with relation to the axis of a blank eing operated upon b the machine; and at each end of the mac ine there is a pair of fixed rolls mounted upon the rotatable shafts, there being a pressure roll opposite one pair of said fixed rolls.
My present invention has to do with machines of this character, and the object thereof is to improve their general construction andoperation.
In the accompanying drawings which form part of my specification, I have illustrated my improvements in their preferred form.
Figure-1 of the drawings ,shows an elevation of the complete machine having in its engagement a rod to be straightened; Fig. 2 is transverse sectional view taken on the line IL-II, Fig. 1, showing an upper roll and, its housing; Fi s. 3 and 4 are sectional views taken on the lines III-III and IV-IV, respectively, of Fig. 2; Fig. 5 is a transverse sectional view taken on the line VV, Fig. 1, showing a lower pair of rolls and their housings; Fig. 6 is a plan View of rolls and housing shown in Fig. 0, and Fig. 7 is a sectional view taken on the line VIL-VII, Fig. 5, the roll, however, bein shown with its axis at an angle to that 0% the driving shaft, instead of parallel therewith, as shown in Figs. 1, 5 and 7.
In the several drawings like numerals are used to designate like parts.
The general construction of the machine shown herein is similar to that illustrated in my above mentioned patent, and consists of shafts 1 and 1 rotatably mounted in suitable bearings 2, which are secured to each end of the machine frame or bed plate 3. The end of each shaft 1, 1 is rovided with a pinion 4, which meshes witli a gear wheel 5, driven by a power shaft 6. Upon the bed plate 3 of the machine, rolls, adapted to bear upon opposite sides of a blank to be straightened, are suitabl mounted within housings, each of which housings is independently adjustable upon such bed plate. The rolls 7 operating upon the lower side of the blank are arranged in pairs within their housings, and, alternating with such pairs of rolls, single upper rolls 8 bear vertically upon the blank.
The upper rolls 8 and their adjustable housings are illustrated in Figs. 1, 2, 8 and 4 of the drawings. Each roll 8 is rotatably mounted upon a sliding bar 9, which may be vertically adjusted within the guide-frame 10'by means of a screw 11 and hand wheel 12. The housing of each roll 8 comprises two main parts, a base portion 13 clamped to the frame 3 by bolts 14, and the above mentioned guide frame 10. To the end that the axis of the roll 8 may be adjusted angularly with relation to the axis of a blank, and thereb be made a feed roll, the guide frame 10'1s provided with o positely disposed outstanding feet 15 ad tipted to rest upon the top lugs 16 of the housing base 13, said feet 15 having slots 17 through which clamping bolts 18 extend and engage the l lugs 16.
Whilst-he above described housing for the pressure rolls does not differ in the manner of its operation from that shown in my early patent, it will be observed that greater r1- gidity of its roll 8 is effected by reason of the fact that the guide frame is secured to the base portion of the housing by securing members. disposed on opposite sides of the roll-carrying bar rather than on one side thereof. I
The lower rolls 7 are particularly illustrated in Figs. 1, 5, 6, and 7. Each of such rolls is mounted within a two-part carrier. block 19, 20' clamped together as by bolts 21. "The bearing surface of the blocks is,
cylindrical and rests upon a correspondingly concave'surface of a bearing plate 22, the radius of curvature of said contacting surfaces being struck from the centerof the roll 7 The bearing plate 22, as will readily be seen, is clamped to the bed plate 3 by bolts 23, and each pair of carrier blocks 19, 20, is in turn clamped to the bearing plate 22 by means of a bolt 24 extendin through a slot 25 in said bearing plate, w ich plate is also provided on its lower side witha convex" curved surface 26. The tops of the carrier blocks 19, 20 are provided with curved slots 27, through which a bolt 28 extends and clamps together the carrier blocks of a single pair of rolls 7, the arrangement being *such the axes of the rolls 7 may be placedat an angle to the axis of the blank to be straightened, as well as at an angle with relation to each other.
As in my earlier patent, the rolls 7 are mounted upon and driven by the shafts 1, 1*. To the end, however, that the shafts may not be weakened by the manner of securing the rolls thereto, and that greater driving force may be had, I form shoulders on the shafts 1, 1 integral therewith and preferably extending from one of its end bearings to the other. As shown herein such shoulders may be formed by providing angular grooves in the shaft, which in section then appears as cross-sha d (see Figs. 2 and 5). Each roll 7 is rigi ly secured to asleeve 29 adapted to be slipped upon the shafts 1, 1, and having inwardly-extending projections 30 of such configuration as to engage the ooves formed in said shafts. The projections 30, as will be seen, taper from a high point at the center of the sleeves to the end thereof, the construction being such that the rolls may within certain limits be driven with their axes angularly disposed with relation to the axes of the driving shafts, the limit of such angular position being shown in Fig. 7.
In the operation of my improved rod or tube straightening machine, the axes of the pressure rolls 8 and the driven lower rolls 7 are first adjusted to the desired a'ngulai'ity with relation to the axis of the blank to be straightened, which in the drawings is represented as a rod 31, it being understood that any or all rolls may have their axes.
angularly disposed to such rod, and .that when so adjusted they become feed rolls as well as straightening rolls; also the pressure rolls 8 are adjusted vertically to the required height depending upon the diameter of the rod to be straightened. Still a third adjustment of the rolls is effected by adjusting the housings thereof upon the bed 3 of the machine, and for such adjustment it will be observed that all the housings may be moved to any desired relative positions upon the bed p-lateby unloosening their respective clamping bolts. The lower rolls 7 are driven by the shafts 1 and l and by their action and the cooperation of the pressure rolls 8 the rod will be drawn between the rolls, and the kinks and bends in it removed.
I do not wish to limit myself to the details of construction shown herein for obviously many changes may be made by those skilled in the art without departing from the spirit of my invention.
I claim herein as my invention:
