This invention relates to what is known in the art as coping machines.

The principal object of the invention is the provision of a new and improved ma- 5 chine for removing or severing portions of the webs and flanges from structural beams and thelike.

Another object of the invention is the provision of a new and improved machine for operating on various forms and types of metallic plates, channels, beams, angles, and the like, by arranging the mechanism so that the tool or tools are drawn instead of pushed during the operation of the device.

A further object of the invention is the provision of a new and improved coping machine having a plurality of cutting and shearing tools mounted on a turret and the Whole being so constructed that it will be composed of a minimum number of parts and occupy a minimum amount of space.

A still further object of the invention is the provision of a new and improved turret coping machine that is simple in construction, easily assembled, cheap to manufacture, efficient in operation, that may be readily adjusted to operate on Various types of me: tallic objects, that is strong, durable and economically operated and that is not likely to become broken or get out of order.

Other and further objects and advantages of the invention will appear from the fol lowing description taken in connection with the accompanying drawings, in which 5 Fig. 1 is a plan View of the device with the cover for the power mechanism removed;

It is common practice to providethe conventional power punches with coping attachments whereby the punch is converted into a machine for performing metal cutting and shearing operations. This arrangement is cumbersome and necessitates the expenditure of considerable time and labor in effecting the changes.

In power punches, it is the usual practice tomount the mechanism for reciprocating the punch in the arm or overhanging portion of the frame. This arrangement necessitates the use of large immovable frames which not only occupy considerable space in the factory but render the device cumbersome, unwieldy and limited to a very great extent'as to the sizes of the beams, plates,

bars and the like that may be operated upon.

The present invention contemplates a machine for cutting and shearing metal plates, bars, beams and the like in which a plurality of sets of cutting and shearing tools are mounted on a turret, and mechanism provid ed for drawing instead of pushing the reciprocating portion of themechanism.

Referring now to the drawings, on which similar reference characters designate the same parts throughout the specification, the

reference numeral 4 indicates the bed plate on which the mechanism is mounted. This plate is provided with upstanding flanges 5, see Fig. 4, each having vertical shoulders 6, see Fig. 2, at the rear thereof. The base 10 of the coping machine is provided at each side thereof with the laterally extending flanges 7, best shown in Fig. 4, which rest on and are secured to the flanges 5 by suitable fastening means, as the bolts or screws 8. The base 10 is also provided with vertical laterally extending flanges 9 which engage, and are secured to, the shoulders 6, as by, means of bolts or screws 3, see Fig. 2. This arrangement permits the base to be readily removed from the bed plate or support 4.

A turret 11 is rotatably mounted in any suitable manner on the base 10. In the manner selected to illustrate one embodiment of U invention, the upper end of the base 10 is provided with a vertical cylindrical opening 12 within which the lower reduced cylindrical portion 13 of the turret is inserted. The reduced portion 13 of the turret forms an annular shoulder 14 which is adapted to engage a corresponding annular flange 15 on the upper end of the base 10 for supporting said turret. The parts are held in assembled relation in any suitable manner. As shown, the turret 11 is provided with a de pending flange 16 to which is attached the retaining member 17 which engages beneath the flange 15. The retaining member 17 is preferably a ring gear for rotating said turret, as will presently appear, and is secured in position in any suitable manner as by means of bolts or screws 18.

The turret 11 and base 10 form a support for a head 19 which is provided with a reduced portion 21 for slidably engaging an axial opening 22 in the turret 11.

In order that the device shall be of uni-- versal application, it is necessary to provide a plurality of tools of different types and sizes. The larger tools for doing the'heavy work are too bulky and cumbersome to operate on small channel bars or I-beams, for instance, and the lighter tools are not strong enough for the heavy work. It is also often desirable to perform different operations on the article without removing the same to another machine. In the present invention the head is provided with a plurality of tools which, for simplicity of illustration and convenience of description, are limited to three cutting tools and one shearing tool.

As shown, the head 19 is provided with radially extending arms 23, 24, 25 and 26, which are provided with the tools 27, 28, 29 and 31 respectively. These tools are adapted to cooperate with tools or die members 32, 33, 34 and 35 on the turret. As shown, a die or tool supporting ring or plate member 36 is mounted on the upper end of the turret, being interlocked therewith by the tongue and groove connection 37, see Figs. 3 and 4.

The parts are held in assembled relation by any suitable means as the bolts or screws 38, see Fig. 5, which extend down through the ring or plate member and engage the top of the turret.

The tools 27 and 31 are cutting tools and are preferably though not necessarily rectangular, and are attached to the under side of their respective arms in any suitable mannor, as by means of the bolts 39 and 41 respectively. These tools are provided with cutting edges on three sides. The cooperating tools or die members 32 and 35 are secured to the ring or plate member 36 in a manner that will now be described.

The ring or plate member 36 is provided with rectangular radially extending notches 42 and 43 in which the tools 32 and 35 are assembled. Each of these tools is in the form of an open rectangle, and since the two are substantially alike only one need be described. The tool 35 is preferably though not necessarily composed of the side members 44 and 45 and the rear member 46. The members 44 and 45 are secured in position by any suitable means as the bolts 47 and the member 46 is secured in a like manner by the bolts 48.

The tool 29 is so constructed that it may be used for removing portions of the flange of a relatively small I-beam. In order to accomplish this the arm 25 is provided with a slot 49 in which the tool is adapted to be inserted. The shank of the tool is rectangular in cross-section and its outer end terminates in a downwardly extending projection 51 which constitutes the cutting edges of the tool. Portions of the tool are removed as at 52 so that the tool will not come in contact with the upper flange of the I-beam 53 during the operation of the machine.

The tool 29 is held in the slot in any suitable manner. As shown, the rear end of the tool is wider than the forward end and a wedge 54 is adapted to be inserted between the upper end of the tool and the upper end of the slot 49. The wedge 54 is held in position by a .setscrew 55 which engages said wedge at an angle so as to tend to force the same into wedging engagement with the tool 2-9.

The cooperating tool 34 on the plate mem ber 36 is substantially the same form as that already described. It differs from those -already described in that it is much smaller and is adapted to operate on smaller bars and beams. The side members and .57 of the tool 34 are held in position by screws 58 and 59 respectively, the heads of which are adapted to clamp these members against the top of the turret.

In order to remove the severed portions of the metal the turret is provided with downwardly and outwardly extending passages 61, the upper ends of which terminate directly below and conform to the shape of the opening formed by the lower cutting tools or dies. The walls about the passage at the upper end of the turret form ledges 62 for supporting the tools 32, 34 and 35.

The tool 28 of the arm 24 is preferably a shearing tool and comprises a blade which is adapted to cooperate with a blade 63 carried by a tool holder 64 mounted on the ring or plate member 36. The turret block may be apertured as at "beneath the shearing mechanism in order to lighten the block and render the same symmetrical. A suitable bar may be inserted in holes (3.: or 70 for manually turning the turret if desired.

The ring or plate member 36 is provided it'h upstanding flanges 650, 6G0, 670 and 680 which engage each side of the arms 23,

24;, 25 and 26 for preventing rotation of the head relative to the turret. If desired, wear plates'69 may be inserted between the flanges and the sides of the arms. 7

Suitable means are provided for reciprocating the head 19. In the form of the device selected to illustrate oneembodiment of the invention, the head is reciprocated by being drawn instead of pushed. As shown, the head 19 and downwardly extending projection 21 are provided with an axial opening 65 through which the cylindrical drawbar 66 extends. The bar 66 is provided at its lower end with a bearing head 67 mounted to reciprocate in guides 68 carried by the base 10, see Fig. 4. The bearing head 67 is provided with suitable bearing blocks 80 for engaging an eccentric 69 on the power shaft 71, suitable bearings 72 being provided for said shaft in the base 10 of the machine, see Fig. 3.

In attaching new tools to the tool holders it is desirable that means be provided whereby the head may be moved by manually operating the shaft 71. Sometimes, the blades or tools do not fit perfectly, and by this method the head may be eased down to test the parts without doing any damage to the tools even though they interfere. As shown, the outer end of the shaft 71 is preferably reduced and a nut 90 issecured thereon. The nut 90 is provided with radial openings '95 for receiving a bar for manually rotating the shaft 71.

The upper end of the drawbar 66 is screwthreaded and a nut 73 engages. the. same. In order to prevent the nut from being turned when the turret and head are rotated means are provided for locking the nut to the drawbar. As shown, the upper end of the bar is notched for receiving a bar 7% which has pointed ends engaging serrations on the side wall formed by countersinking the outer end of said nut as at 75.

If desired, a nut or a plurality of washers 76 may be provided between the projection 21 and the reciprocating head 67 for adjusting the head 67 on the bar 66. If it is desired to lower the head 19 on said bar one or more of the washers 76 may be re moved.

In order to eliminate lost motion in the bearings during the power stroke of the head 19 and in order to counterbalance the weight of said head, a spring 77 is employed beneath the reciprocating head 67 for resisting downward movement of said head.

The power shaft 71 is operated by any suitable mechanism. The power plant for operating the machine is preferably located at a sufficient distance from the machine to be entirely out of the way. The parts are so arranged that the power shaft and a large part of theplant are located beneath the floor line 78 whereby none of the 0p As shown on the drawing, the power shaft 1 is operated from the motor 79, see Fig. 1, through the reducing gears 81, 82, 83, 84, 85 and 86 respectively.

A clutch 87 which is normally declutched is interposed between the gears and the power shaft 71. The clutch is normally released and is adapted to be moved to clutching position by a foot lever 88 pivoted to the base, and connecting mechanism 89. The lever 88 is provided with a treadle 91 extending across the front of the machine and having its opposite end supported by an arm 92 pivoted to the opposite side of the base as at 93. 1

Since the details of the mechanism for op erating the power shaft 71 constitute no part of the present invention, the same being in general use, it is not thought necessary to illustrate or further describe the same.

A casing is providedfor protecting the mechanism for operating the power shaft.

If desired suitable power operated mechanism' may be provided for rotating the turret. As shown, one member 96 of a friction clutch is secured to the outer end of the countershaft 97, see Fig. 1, which is adapted to be engaged by the other member 98 of said clutch. The clutch member 98 is slidably mounted on a power shaft 99, the for ward end of which is provided'with a bevel gear 100 meshing with a corresponding bevel gear 101 on the counter shaft 102. The upper'end of the counter shaft 102 is provided with a spur gear 103 which meshes with the ring gear 17 on said turret for rotating the same.

A lever 104 is provided for controlling said clutch. The lever is pivotally mounted on the base 10 as by means of the bracket 105 and is connected to a yoke 106 engaging the clutch member 98 by a link or rod 107 in the usual manner.

In the operation of the device,the turret is turned to the desired position, either manually or by power by manipulating the lever 104; for receiving the beams or bars to be operated upon, which are usually conveyed to the machine by a crane, or may be supported by a table or other form of support.

It is often desirable that a plurality of operations be performed on one bar or beam. In such case, it is only necessary for the operator to turn the turret to the proper position instead of changing the position of the bar. This is considered an important feature of applicants invention because with long bars or beams it is often impossible to turn the same in the shop.

The operating mechanism is removed a suflicient distance from the coping machine to give the workmen free access to the mat chine from all sides, and is lowered beneath the level of the turret in order that bars or beams may be made to approach the machine from any direction without being interfered with by said mechanism.

For convenience of description the arm 23 and tools associated therewith will be referred to and indicated on the drawings as station I, see Fig. the arm 2% and tools associated therewith as station II; the arm 25 and tools associated therewith as station III; and the arm 26 and tools associated therewith as station IV.

When it is desired to remove portions of the flanges of the smaller sizes of I-beams 53 and the like, station III is moved to a convenient position for receiving said beams. If the intermediate sizes of beams, as the beams 1.08, are to be operated upon, station I is moved to position to receive the beam. If the largest sizes of beams, 109, are to be operated upon, station IV is moved to a convenient position to receive said beam. If a shearing operation is to be performed, station II is moved to a convenient position to receive the work to be operated upon.

In the erection of structural iron it is often necessary to connect the ends of I- beams to the sides of similar beams which extend at right angles thereto, in which event it is desirable that the ends be reduced to a .sufiicient extent to enter between the flanges of the bar or beam to which it is attached. In order to reduce the end of an I-beam it is necessary to remove the flanges at the end of the bar as indicated at 110 in Fig. 7. After portions of each flange are removed the web 111 of the bar or beam is sheared as shown at 112 in Fig. 7
