FLASH WINDER.

Application filed February This invention relates to machines for compacting metal strips, scraps, or flashings of metal so that they may be handled safely and occupy a minimum amount of space with maximum weight.

In the shaping or forming of metal articles by drop forging, there is usually an is obtained for the space taken up.

excess amount of metal which is subsequently returned to the charging box of the furnace for remelting. This metal is frequently shipped a considerable distance to the mill, and it is therefore desirable that the pieces or scraps be bundled as compactly as possible so that the maximum weight It is apparent that when these scraps are shipped without being bundled, but in straight form, a considerable space is utilized without material weight. Furthermore in forging some parts, the scrap or flashing produced is particularly sharp pointed and has been found decidedly dangerous to workmen handling it, inasmuch as the points are so sharp as readily to pierce thru clothing.

Objects of this invention are to overcome the above difficulties; to provide a simple and efficient machine for compacting flashings or metal scraps occupying but a relatively small space and having no sharp points dangerously positioned; to provide a machine for rolling metal scraps into a compact coil and thereafter automatically discharging the coils therefrom; to provide a new and improved process of bundling metal scraps which is decidedly simple and may be embodied in machines of suitable construction; and to provide a scrap bundling machine having the new and improved features of construction, arrangement and operation hereinafter described.

The invention is shown by way of illustration in the accompanying drawings,- in which:

Fig. 1 is an end elevation of a machine for bundling metal scraps; Fig. 2 is an op posite end view of the machine; Fig. 3 is a side elevation partly in section; Fig. 4 is a side elevation showing the position of the parts after the operating handle has been moved to close instantaneously the starting contacts and to enable the upper latch to 17, 1926.

catch the ring on the rod; Fig. 5 is a diagram of the electric control circuit for the operating motor; and Fig. 6 is a detail view of the end portion of the trip lever.

The illustrated embodiment of the invention comprises a bed plate 1 upon which a machine frame 2 is mounted, and located in the upper portion of the frame 2 is a horizontally disposed, axially movable winding shaft3. A hand wheel 4 is connected to one end of the shaft and the opposite end is formed with a transverse slot- 5 of sub stantial depth.

The winding shaft 3 is connected by means of a key 5 to an elongate sleeve 6 rotatably mounted in the frame. The key 5 is slidable in a longitudinally elongate key way 7 in the winding shaft 3 to permit the shaft to move axially concomitant with the rotation thereof. Mounted on the inner end of the sleeve 6 is a worm wheel 8 which is clutched thereto as will be hereinafter described. A worm 9 fixed to a drivevshaft 10 meshes with the wheel 8, and the shaft 10 is operatively connected to an electric motor 11. It will be readily seen that rotation is imparted to the winding shaft 3 from the drive shaft 10 through the connections described.

Slidably mounted in the frame below the. winding shaft 3 and in parallel relationship thereto is a bar 12 supported in bosses 13 on opposite ends of the frame, and this bar is formed with a yoke 14 extending laterally therefrom and engaging at one end an annular groove in the adjacent end of the winding shaft 3. When the bar 12 is moved horizontally in the frame, the winding shaft 3 is correspondingly moved, and by means of the driving connection between the shaft and sleeve 6, rotation of the shaft is permitted during this movement. Mounted in the lower part of the machine frame is a rotatable drum 15 fixed to a shaft 16 which is supported in bearings 17. Secured to one end of the shaft 16 is a gear 18 meshing with a pinion 19 which is fast to a shaft 20 and on this shaft is a worm wheel 21 meshing with the worm 9 so that the driving shaft 10 imparts rotation to the drum 15 and winding shaft 3.

Depending from the bar 12 is an arm 22 having on the lower end a roller 24 which extends into a counter sunk cam groove 25 which extends around the drum 15. For purposes of illustration it may be said that the cam groove 25 is divided into two sections, an annular section 26 and a V-shaped section 27. During the rotation of the drum 15, the roller 24 remains in the cam groove and when forced into one leg of'the V-shaped groove 27, the bar 12 is moved horizontally (to the left in Fig. 4), and upon being forced into the other leg of this groove, the bar is moved in the opposite direction (to the right in Fig. 4). The length of the section 26 is so chosen that the winding shaft 3 may rotate several times before the roller 24 engages the V-shaped groove.

Metal scraps or fiashings A are fed to the machine thru a guide or trough 28, and mounted on a bracket 29 adjacent the inner end of the trough 28 is a roller 39 over which the flashings ride. In this manner the metal is delivered to the winding shaft 3, the strips being inserted through the slot 5 in the projecting end of the winding shaft.

When the motor 11 is energized, the winding shaft 3 and drum 15 are simultaneously rotated and the annular section 26 of the cam groove first engages the roller 24. With one end of a metal strip A in the slot 5 and the remainder resting on the trough 23, it will be apparent that upon rotation of the winding shaft, this strip is coiled around the outer end thereof. YVhen the roller enters the V-shaped groove and the shaft 3 commences to move horizontally, the coiled strip is forced against the machine frame. {DEC upon further movement of the shaft the coiled or bundled strip is forced therefrom, the end of the shaft being tapered so that it will drop off readily. The winding shaft thereafter returns to normal position as heretofore described with the slot positioned horizontally to receive another $1 rip or scrap.

As indicated in Fig. 2 the sleeve 6 is clutched to the gear wheel 8 by a spring pressed ball 31 in a groove 32. This provides a driving connection between the sleeve and gear wheel which enables the haft 3 and sleeve 6 to be turned in one direction by the hand wheel 4 to position the slot 5 horizontally in the event it does not stop in the proper feeding position.

A remote control mechanism is employed for starting and stopping the ei tric motor 11 and for this purpose a starting contact 33 is supported by the machine frame and a starting contact 34 connected to one end of a spring arm 35 is engageabie with a contact 33. The portion of the arm 35 carrying the contact 34 is normally sprung away from the contact 33 and the contacts 33 and 34 may be termed the starting contacts. The opposite end of the arm 35 carries a contact 36 which is engageable with a contact 37 carried by the machine frame and the contacts 36 and 37 are normally held in engagement.

As diagrammatically illustrated in Fig. 5 current is supplied to the motor through the loads 38, 39 and 40 and when the starting contacts 33 and 34 are momentarily engaged, current flows through the leads 3S and 41, starting contacts, arm 35, stop contacts, lead 42, through an electromagnet 43, lead 44 to the main line 40. The current passing through the magnet 43 draws the armature thereagainst and the armature 45 is connected in a suitable manner to switches 46, 38, 39 and 40 which move corresponding- 1y to the armature.

After the starting contacts 33 and 34 have been momentarily engaged they are sepa rated by action of the spring arm 35 so that thereafter current flows from the supply line 38 through a portion of the lead 41, through lead 47, switch 46, lead 48, spring arm 35, stop contacts 36 and 37, lead 42, electromagnet 43, lead 44 and to the line 40. In this position the switches 38% 39 and 40 bridge the gap in the motor lines 38, 39 and 49 thereby energizing the electric motor 11.

From the above it will be seen that current will be supplied to the motor so long as the stop contacts 36 and 37 are in engagement, but as soon as they are disengaged the electron'iagnet 43 becomes deenergized and suitable spring means may be employed for moving the armature 45 and associated switches to the normal position indicated in Fig. 5.

Manually operated means are employed for moving the contact elements and 34 into engagement with each other to start the motor, and automatic means are also provided for separating the stop contact elements 36 and 37 for shutting off the motor after a predetermined movement of the parts. In order manually to move the contact elements 33 and 34 into engagement, a hand operated lever 49 is pivoted intermediate its ends at 50 to the machine frame and is connected at its lower end to a hori zontally slidable rod 51 supported in bearing members 52 and 53 at opposite end portions thereof. The upper portion of the lever 49 is formed with a laterally extending arm 54 which normally engages the upper surface of the spring arm 35 in the region of the contact element 34.

Fixed to and rotatable with the main driving shaft 10 is a brake drum 55 and encircling the drum 55 is a brake band 56, one end of which is secured to the rod 51 and the opposite end of which is fixed to the bearing member 52. It will be seen that clockwise movement of the lever 49 moves the contact. element 44 into engagement with the contact til] element 83, the brake band 56 being released from the drum by the horizontal movement of the rod 51.

Fixed to the opposite end portions of the rod 51 is an annular member 57 winch is engageable by a pivoted upper latch 58 when the rod 51 is moved to the left by the operhen the bar 12 moves to the left the arm 59 first engages the inclined surface 61 on the underside of the latch 58 and raises the same thereby releasing the member 57 which is then caught by a lower latch 62 which is pivoted at one end to a horigiontal bar 63.

It will be noted that the upper surface of the latch 62 is formed with a raised portion 6% having oppositely inclined portions and when the parts are at rest this raised portlon 6st engages the underside of the arm 59, thereby holding the latch away from the member 57. The latch 62 is snapped into latching relation with the member 57 by a leaf spring engaging the underside thereof.

As the bar 12 continues its movement to the left. the arm 57 next engages the pivoted end portion 66 of a. bell crank trip lever 67, the upper portion of which engages the underside of the spring arm 35 in the region of the contact element 36. The engagement of the pivoted end portion 66 by the arm 59 moves the portion 66 upwardly and out of the way and the arm 59 continues its travel.

After the arm 59 has reached the limit of its travel to the left it starts to the right and first engages the pivoted end portion 66 of the trip lever 67 and continuing its movement causes the trip lever 67 to rotate in a countercloclnvise direction, thereby to raise one end portion of the arm 35 to sepa ate the stop contacts 36 and 37. By this means the motor 11 is deenergized but sutlicient momentum has been attained to continue the travel of the bar 12 and winding shaft to its extreme right hand position.

The arm 59 next moves under the inclined surface 61 on the trip lever 58 allowing it to drop downwardly, and shortly thereafter the lower surface of the arm 59 engages the raised portion 64- on the latch 62 and cams this latch out of engagement with the member 57 which is quickly forced to the right by means of the coil spring which has again been compressed by the movement to the right of the arm 59. This movement of the member 57 correspondingly moves the rod 51 and tightens the brake band 56 around the drum 55 which operates to stop the rotation of the driving shaft 10. A stop 68 on the rod 51 engages the bearing member 52 thereby to limit the movement of the rod to the left.
