ADJUSTABLE, ROTARY PRESSING mcgmm Filed May 10, 1927 I 2 Sheets-Sheet 2 V Patented June 24, 1930 EVERETT R. MANLEY, OF FAIRMONT, WEST VIRGINIA ADJUSTABLE ROTARY PRESSING MACHINE Application filed May 10, 1827. SerialNo. 190,217.

My invention relates generally to pressing machines, and more particularly to the hot or cold pressing of electric coils, as motor and armature coils, and to the hot or cold pressing of such forms as mica insulating tubes and the like.

In my device a new method is'employed in the process of hot or cold pressing of armature coils, and it differs from the old method inthat a square or multisided rotor is "used, each side of which is a working face for the pressing of the coils, thereby affording a continuous pressing, cycle of operation in one press, and a considerable sav ing oftime and movement of the operator. I In the presses in present use there'is one stationary working face for the pressing operation embodied in one machine, making t necessary to employ a series ofmachines to allow for the proper heating interval of time between the insertion and removal of the'eoil without suspending operation.

Furthermore, better results are produced than those in resses now in use owing to thefact that acilities are afforded for the proper adjustment of the parts pressing the coil thus permitting the pressing of a coil to. any desired size of cross section.

' Furthermore, in my invention, the con struction and arrangement of the various parts for the pressing operation are such that there are noloose parts that need removal during the entire cycle of operation. Presses in present use have loose parts that have'tobe removed at some time during the cycle of operation. The removalofjthese loose parts causes extra labor and a'l'oss of time, and'does not give a machine that is compact and self-contained.

Furthermore, my invention provides adjustable and movable means of pressing armature and motor coils of'various shapes and sizes. Armature and motor coils in most cases are of such shape that the ends are offset from that part of the coil that needs pressing. My machine is so constructed and its partsso arranged as to readily press colls of practically anyshape or size. Furthermore, my invention is'readily and conveniently adaptable to the use of gas,

of the rotor.

It may be stated that each face of the rotor is identical in every detail for the pressing of the coils. Fig. 2 is. a,

vertical section thru the rotor on line 22 of Fig. 1.

Fig. 3 is a vertical section thru the rotor on line 3-3 of Fig. 1, and with parts removed from two working faces, and

with center shaft removed. Fig. 4 is a section on the line 4-4 of Fig. 1, showing the top pressing yoke in relation to the lifting springs, and the method of holding the side pressing bar to the side bar holder; Fig. '5 is a section onthe line 55 of Fig. 1, showing the adjusting screw for regulating the downward movement of the top pressing yoke.

I The half bearings 1, the legs 2, and base board 3, constitute the supportingframe of the machine.

, The rotor 4, as shown, has four working faces and may have more or less, but prefer- (See Figs. 1,2, and 3.) Each working face for pressing the coil or object has identically the same equipment upon it.

holder 15 by means of screws 16. The screws 16 are threaded into the holder 15, and have round turned ends that fit into a longitudinal groove 17 in the side bar 14. The side bar may thus be moved in a longitudinal direction or removed and another one readily'put in its place. (See Figs. 1 and 3.)

The side bar holder is actuated back and forth by means of the screw 18, to which is rigidly attached a wheel 19 with a handle 20. The screw 18 is screwed into the fulcrum block 21, which fits into a longitudinal recess in rotor 4, and may be moved longitudinally across the face of the rotor. The side pressing bar 14 may thus be moved parallel to the top pressing yoke the entire length of the working face of the rotor. This feature of my invention particularly facilitates the pressing of motor and armature coils of such design that the offset part of the coil must be free from interference during the pressing operation. When such a coil is placed in the press with the offset end lapping over the end of the rotor, the fulcrum block 21 may be moved to any position necessary to apply the side pressing bar 14 to the center of the coil, thereby giving a uniform pressure to the coil. The fulcrum block 21, is held to the rotor 4 by two bolts 22, which pass thru the elongated slot 23. A plate 24 (See Figs. 1 and The screw 18 has a turned down end with a circular groove 25 cut into it and fits into a hole in the side bar holder. A screw 26, in

, side bar holder 15, has a turned down end to fit into this circular groove in the end of screw 18, thus holding the side bar holder securely to the screw 18. A shoulder 27 on screw 18, takes the thrust incident to the pressing operation of the side pressing bar 14. This thrust is taken thru the screw to the fulcrum block 21, and thence to the recess in the rotor 4. (See Fig. 3.)

The coil to be pressed is placed on the rotor at 28. It will be observed from Fig. 3 that the side pressing bar 14 is so designed, that, in conjunction with yoke 8, the final size of the coil is determined. This is at fected by the yoke and side bar taking contact at point 29, when the coil is pressed to its final size. Various cross sectional sizes of colls may be made by the use of side bars of suitable dimensions at point 28.

Or the size of coil to be pressed may be determined as shown by Figs. 4 and 5. The side bar 14 is designed so as not to make any contact at point'29, as shown in Fig. 4, but the downward movement of yoke 8 is l mited by setting the adjusting screws 13, F1gS. 1 and 5, so as to give the required size of coil in space 28.

The heating of the rotor may be done by any well known method but for convenience the drawlngs show the application for heatby gas,,which the method. most commonly used. The valve 30 has a stem 31, which fits into a hole 32 in shaft 5, and a swivel joint is provided by means of a packing gland 33, which permits the valve to remain stationary when the rotor is revolved. The hole 32 extends to a point where the four pipes 34 are attached, to, the) shaft. Near the rotor a burner 35 is provided to regulate the mixture of air and gas. The noses of the burners fit into pipes 36, which are fitted into holes in the end arms of the rotor. The opposite ends of the pipes 36 are capped. The pipes 36 have perforations to emit the gas and provide the flame for heating. It will be noticed that the pipes 36 are placed so that the flame will give the greatest heat to that part of the rotor immediately underneath the place 28, where the coil will be inserted for pressing. (See Fig. 3.) As stated before any method of heating may be employed such as gas, hot water, steam, or electricity. The openin s 37 in the rotor are for the application of hot water, steam, or electricity. Electric coils may be inserted in the openings 37 or the openings may be used as part of the circuit for hot water or steam. In any case suitable attachments and fittings may readily be used for such heating'methods. In the case of a cold press the openings 37 will be in the circuit of cold water or cold air, and suitable attachments and fittings will be employed. p

The operation of my invention for hot pressing will now be explained. The yoke 8, and the side pressing bar 14, are withdrawn from the position shown in Figs. 3 and 4, by means of. lever 11 and wheel 19 respectively. The coil is placed in space 28, and then the yoke 8 is screwed down, and side bar 14 screwed forward to press against the coil. The rotor is then turned "around to the next working face and. another coil is inserted. This process continues until the first coil inserted comes back to its initial position and a final tightening of the yoke 8 and side bar 14 is made. This final tightening may be made at any stage of the revolution of the rotor. The coil is then removed by releasing the yoke 8, and side bar 14, and transferred to an adjacent cold press,.and another coil is put in the rotor. The rotor is revolved and the oncoming coil removed to the cold press and so on the process indefinitely continues. v

I am aware that prior to my invention, hot pressing machines have been, made consisting of one working face and for the application of heat in various forms. I therefore do not claim such a combination broadly; but

Iclaim:
