To all 'whom it may concern:

Be it known that l, GEORGE PAUL THOMAS, residing at Glenshaw, in the county of fillegheny and State of Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful improvements in Angle-Planers, of which improvements the following is a specification.

My invention relates to metal planers and has particularly to do with plancrs for cutting or trimming the outer edges and the heels of angies such as are use in the construction of steel bridges, buildings, ships, etc.

T he object of my invention is to providen an angle planer whereby deep cuts may be simultaneously made upon the outer edge or edges and upon the heel of different sized angles, each angle being engaged and fed to the cutter during the planing operation in such a manner that it will not be bent or otherwise distorted.

In the accompanying sheets of drawings, which form part of my specification, the preferred embodiment of my invention is illustrated. Figure l is a side elevation of the angle planer; Fig. 2 a plan view thereof; F ig. 3 an elevation of the right end of the machine as viewed in Fig. l; Fig, a view of the reducing gearing of the driving connections, the plane of view b eing indicated by the line lVL-lV Fig. 3; Fig. 5 a view of the driving connections of the various feed rollers, the plane of view being indicated. by the line V-V, Fig. 3; and Fig. 6 a side view of the general' arrangement and construction of feed rollers, cutters and guides, the

lane of view being indicated by the line l-VI, Fig. 3. I

In the machine which I provide, an angle to be planed is fed longitudinally by and between a plurality of pairs of feed rollers, between which pairs several cutters are ar ranged in positions to plane the heel and edges of the angle. l

While various numbers of pairs of feed rollers may be used, l preferably provide three pairs constructed and arranged in the manner particularly indicated in Fig. 6. These rolls may be designated as entering rolls l and l, intermediate rolls 2 and 2a', and discharge rolls 3 and 3a. As seen clearly in Fig. 3, the rolls of each pair are preferably provided with coperating concave and convex conical faces adapted to engage both sides of both legs of an angle 4. rlfhe rolls having concave faces may be the upper rolls l, 2 and 3, and the rolls having the convex faces the lower rolls la, 2a and 3a. To facilitate the gripping of an angle, the faces of the rolls may, as indicated, be suitably roughened. Between the entering and intermediate pairs of feed rolls there is arranged a vertically adjustable cutter 5 adapted to plane the heel of an angle, and between the intermediate and discharge pairs of rolls there are arranged two adjustable cutters 6 and 7 for planing the outer edges of the legs of an angle. These cutters may be of any shape depending upon the character of cut desired to be made.

With further reference to the parts of the angle planer which act directly upon an angle'as it passes through the planer, there may be provided a downwardly inclined grooved shoe 8 at the discharge side of the entering rolls l and la, adapted to direct downwardly the forward end of an entering angle so that the heel of the angle may be properly positioned with respect to the heel cutter 5. Below the cutter 5 there is an idle roll 9 adapted to hold the angle rmly against such cutter. Between the intermediate and discharge pairs of rolls there are upper and lower idler rolls 10 and l0a for firmly holding an angle in proper position to be operated upon by the edge cutters 6 and 7. Finally7 at the discharge side of the pairs of rolls 3, 3a there is provided a vertically adjustable straightening roll 1l adapted to prevent the angle from bending upwardly.

The several rolls and cutters thus far eX- plained are mounted in a frame which preferably comprises a bed-plate l2 and three vertically disposed parallel housings 13, 14 and l5. Bot-h the upper and lower feed rolls of the three pairs thereof are positively driven and to suoli end each feed roll is mounted upon a shaft having bearings in each of the three housings. The shafts for the upper rolls are indicated by the numerals 16, l? and 18, and those upon which the lower rolls are mounted by the numerals 16a, 17a, and 18a. rlhe driving connections for these rolls will be presently explained.

That the planer may be used for planing angles of dierent thicknesses, means are provided for adjusting the cooperating feed rolls with respect to each other. To such end, in the illustrative embodiment of my invention, provision is made `for adjusting the upper feed rolls. For suoli purpose each bearing in the frame housings 13, 14 and 15 for the several shafts 16, 17 and 18 consists of a vertically slidable pillow block 19, to the upper side of which there are attached rods 26 extending through suitable openings formed in a plate 21 secured to the end of a screw 22. Between the block 19 and plate 21 there is a strong coil spring 23, the initial compression of which is eected by tightening nuts 24 on the outer ends of rods 20. At the upper end of each of the screws 22 there is a worm wheel 25 secured to a sleeve 65 interiorly threaded to engage the threads of the screw` 22. Hence, by rotating the worm wheels, the screws 22 may be raised or lowered to adjust the position of the blocks 19.

The adjustments of the shafts 16, 17 and 18 are preferably effected separately by inde pendently operated mechanism. In Fig. 2 it will be seen that the worm wheels 25 for adjusting the three bearings of the shaft 16 each mesh with .a worm formed or mounted on an adjusting shaft 26 provided at its end with a hand wheel 27. 1n a similar manner adjustingV shafts 248 and 29 each have independent operating wheels 30 and 31 for adjusting'the feed roll shafts'17 Vand 18.

The means for positively driving each of the several feed rolls are such thatfthe required, necessarily large, driving torque may be applied to each of the roll shafts in their various adjustable positions relative to each other; Preferably each roll shaft is proi vided with a pinion, the upper shafts 16, 17 and 18 being provided with pinions 36, 37 and 38, respectively, and the lower roll shafts 16, 17EL and 18L with pinions 36a, 37 a and 38;

` Arranged between adjacent roll shaft pinions and rotatably mounted in the frame housing 15, there are idler pinions 39, 39a, 40 and 40a. The pinion 39 meshes with the roll shaft pinions 36 and'37, the pinion 39a meshes with the roll shaft pinions 36a and 37, and pinions 39 and 39EL also mesh with each other.

To the end that the rolls 1, 2 and 3 (and particularly roll 2) may be freely moved Y vertically, to effect the adjustment already described, and at the same time maintaining through their pinions driving connection with the source of power, the succession of driving pinions 36, 39, 37, 40 and 38 is arranged not in a common plane but in two planes (compare Figs. 2 and 5) pinions 36, 39 and 37 lying in one plane and pinions 32, 40 and 38 in another' plane, pinionsv 32 and 37 being both of them keyed to the shaft 17.V The succession of pinions forming the lower Y sequence namely pinions 36a, 39a, 37a, 40a and is to drive shaft 18a and no other. Shaft 18 is driven from shaft 17 through pinions 32, 40 and 38.

To this arrangement of driving pinions power Vis applied preferably-through one of the roll shafts, and, as shown in the drawings, the power maybe applied to the roll shaft 16a, the power being supplied by a motor 41 mounted upon the bed-plate 12. Between the pinion 42 on the armature shaft of the motor1 and the feed roll shaft 16"L there is a train of reducing gears shown particularly in Fig. 4, such train of gears consisting of a pinion 43 meshing with the pinion 42, shaft 44, pinion 45, pinion 46, shaft 47, pinion 48 and pinion 49, which latter pinion is keyed to the feed roll shaft 164.

1t will be observed with respect to the driving connections that the rotation of the pinion 36al in a direction to feed an angle from right to left will, through the arrangement of pinions indicated in Fig. 5, cause all of the feed rolls to be rotated in the required direction for thus feeding an angle.

Furthermore, by reason of the fact that theV axes of rotation of the upper series of pinions and their points of intermeshing as well lie all in a substantially common plane, the roll shafts 16, 17 and 18 may, without impairing the effectiveness of the interlocking or meshing of the pinion teeth, be vertically adjusted sufficiently to permit the feed rolls to engage angles of the usual range of thickness.

s previously stated, the heel cutter 5 is preferably arranged between the first two pairs of feed rolls, and the edge cutters 6 and 7 between the second and third pair of feed rolls. By thus arranging Vthe cutters the heel and both edges of an angle may be planed from end to end of the angle. Furthermore, it should Vbe noted that the edge cutters offer greater resistance to the advanceof the angle than does the heel cutter. Hence, by placingthe edge cutters between the second and thirdpairs of rolls, greater propelling or feeding power will be applied to the angle at the point of greater resistance to its advance.v

For adjusting thefheel cutter 5, such cutter may be mounted upon the end of a screw 50 adapted to be vertically adjusted by means of a worm wheel 51 and worm shaft 52 which may be rotated by a hand wheel 53.

its will be seen from Fig. 3, the edge cutters 6 and y7 are mounted, respectively,on longitudinally movable screws 54 and 55, which extend in planes substantially parallel to the planes of the legs of an angle passing between the feed rolls. The cutter 6 may be adjusted by means of a hand wheel 56l arranged on the outside of the vertical frame 13. That the cutter 7 may be independently adjusted from the same position, the outer end of its adjusting 'screw 55 is provided with a spiral pinion 57 meshing with a spiral assenza pinion 58 secured to a shaft 59, which shaft extends through the frame housings 13 and 14, and is provided on its outer end with a v hand wheel 60.

so shaping the feed rolls the same feeding pressure will be applied to each leg of an angle with the result that both legs will, if elongated at all by reason of such pressure, be elongated the same amount. Accordingly, there will be no tendency of the angle to bend laterally. ln case of any tendency of Y the angle to bend upwardly, such tendency may readily be counteracted by means of the4 straightening roll 11 arranged at the discharge side of the feeding rolls 3 and 3a. As seen in Fig. 1, the straightening roll 11 is mounted for vertical adjustment, a hand wheel 61 being provided for this purpose. It will be understood that the straightening' roll 11 will be so positioned vertically that it will bear down upon the back of an angle sufficiently to remove any upward bend or kink that may result from the pressure of the feed rollers.

With respect to the mounting and adjustment of the several guides between the pairs of feed rolls, the shoe 8 may be provided with an upwardly extending plate 65 connected to a chuck 66 in which the heel cutter 5 is carried. Preliminary adjustment of the shoe with relation to the chuck may be effected by providing the plate 65 with vertically disposed slots adapted to receive bolts 68 engaging the chuck. The guide rolls 9 and 1()a may either or both be mounted on eccentric bearings such as 69, which, after having been preliminarily adjusted to the required position, may be held in such position by means of a set screw 70. Guide roller 10 may be vertically adjusted by means of a hand wheel 71 secured to a screw 72 having threaded engagement with a trunnion 73 in which the roller 10 is rotatably mounted.

in the operation of the angle planers, the feed rolls, cutters and idle roller 10 are first adjusted according to the size of the angle to be planed and the depth of cuts to be made upon such angle. For adjusting the feed rolls the several shafts 26, 28 and 29 may be turned independently by means of the hand 'wheels connected tc the shafts. For indicating the positions of these rolls, the blocks 19 may each be provided with a pointer 62, and the portion of the housing 13 adjacent. thereto may be provided with a scale 63. The adjustment of heel cutter 5 and shoe 8 is effected by turning the hand wheel 53, the adjustment of the edge cutters 6 and 7 by turning the hand wheels 56 and 60, respectively, and the adjustment of the idle roller 10 by turning the hand wheel 71.

The machine having been thus adjusted, the forward end of an angle to be planed is placed in the grip of the entering pair of rolls 1 and 1a. These rolls feed the angle forwardly, the forward end of the angle being guided by means of the shoe 8 to a proper position with respect to the heel cutter 5. 1n the further advance of the angle the forward end is engaged by the intermediate rolls 2 and 2a, and is finally engaged by the discharge rolls 3 and 3a. Between. the grip of the three pairs of feed rolls the angle is continuously fed forwardly and its heel and edges continuously planed by the the cutters. 1t will be understood that in case it is not desired to plane the back and both edges of an angle, only such cutters need be used as are required to effect the desired planing.
