WIRE-DRAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 427,150, dated May 6, 1890. Application filed J annary 3, 1890. Serial No. 335,740. (No model.)

To aZZ whom it may concern:

Be it known that 1, JAMES E. BURNEs, a citizen of the United States, residing at aterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in ire-Drawing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The principles of my invention are applicable tomachines for drawing all kinds and sizes of wire, but are more especially adapted to machines for drawing fine wire, the special object being to produce a machine which shall be Very compact in its general arrangement, requiring but little room and but little attendance, in which any number of drawings may be produced by a single continuous operation, and which may be threaded up in a mere fraction of the time required for threading up the various styles of wire-drawing machines now upon the market. \Vith these ends in view I have devised the simple and novel construction of which the following description, in connection with the accompanying drawings, is a specification, numbers be ing used to denote the several parts.

Figure 1 is a side elevation of the machine complete, and Fig. 2 a plan view thereof.

1 denotes the bed of the machine; 2, suitablestandards therefor; 8, a reel carrying the wire to be reduced; 4, a block upon which the drawn wire is wound; 5, vertical drawingrollers; 6, an oiling-pan extending longitudinally of the machine; 7, a longitudinal shaft carrying oiling-rollers 8, which turn in the oilpan, and 9 a power-shaft journaled in the standards and having fast and loose pulleys (denoted by 10 and 11) adapted to receive a driving-belt. (Not shown.)

12 denotes a bevel-gear on shaft 9, which meshes with a be vel-gear 13 on a vertical shaft 14, the latter shaft carrying at its upper end a gear 15. The vertical drawing 'ollers extend above the bed and are arranged in longitudinal series on opposite sides of the machine. The shafts of these rollers (denoted by 16) extend belowthe bed, and are provided at their lower ends with gears 17, which mesh with each other, the end gear of each series meshing with the gear 15 and receiving motion therefrom, which they communicate to the other gears in the series, the gear at the opposite end of one series meshing with a gear 18 on the shaft 19 of the block, which also extends below the bed, as is clearly shown in Fig. 1. It will thus be seen that bevelgear 12 on the power-shaft drives the entire train. Longitudinal shaft 7, carrying the oiling-rollers in the pan, is provided with a pulley 20 and receives motion from a belt 21, passing over a pulley 22 on the power shaft. It will readily be seen that the bed of this machine is very narrow, so that it is perfectly convenient for the operator, and that it may be extended to an indefinite length, so that any number of drawings may be produced at a single operation. In the present instance I have shown six drawing-rollers on each side of the machine, and have shown in full lines the machine as provided with four dies, although three addit-ional dies may be used with this construction, if preferred. (See additional dies indicated by dotted lines in Fig. 2.)

The drawings by the four dies shown in full lines is from back to front, and by the three additional dies shown in dotted lines from front to back, necessitating the placing of the dies on the opposite side of the oil-pan.

In practice, however, I preferably arrange the dies and drawing-rollers as shown in the drawings, the relative number of drawing-rollers required for each die depending, of course, I

upon the quality of wire that is being worked and the amount that it is reduced by each die.

In the drawings it will be seen that the right side of each drawing-roller in one series is in line with the left side of the corresponding drawing-roller in the other series. This arrangement avoids any deflection of the wire, except by the drawing-rollers, which insures a perfectly uniform and even product, the wire being drawn through each die just as fast as is required to supply it to the next die in the series, and no faster. As the drawing-rollers all rotate at the same rate of speed,

between side plates 24, which are made integral with or rigidly secured to the bed of the machine.

It will be seen that the operation of thread ing up in myimproved machine is exceedingly simple and easily performed, insuring a great saving of time in this most tiresome operation in the art of wire-drawing.

The operation of the machine is as follows: The operator places the reel containing the wire to be reduced upon a suitablestandard or turn-table at one corner of the machine. I have simply shown the reel in operative position, but have not shown the turn-table, as I employ the device commonly used upon this class of machines. Suppose the reel to be placed at the back right-hand corner of the machine, as seen in Fi g. 1. The wire is passed through the first die, then given a turn and a partial turn around the first drawing-roller in the series at the front, then a turn around the second drawing-roller at the front, then a turn around the first roller in the series at the back, then a partial turn around the second roller at the back, and then through the sec ond die, and so on, there being in the arrangement shown four drawing-rollers acting to draw the wire through each die, the wire making practically an entire lap or more around three of these rollers and merely passing over the other one, the principle being that the wire passes backward and forward across the machine transversely and that the drawing-rollers are arranged vertically. This allows the wire to be readily passed around the rollers by placing it over the top and allowing it to drop to place, which insures an important saving of time in threading up the machine. As already stated, however, if it is not desired to reduce the wire too much at each operation, additional dies may be used and but two drawing-rollers allowed for each die, the wire being given an additional turn around the second and fourth drawing-rollers at the back. This arrangement in the machine illustrated would give the first and second drawing-rollers at the front of the machine to the first die, the first and second rollers at the back to the second die, the third and fourth rollers at the front to the third die, and so on. In practice, however, I preferably use the arrangement shown, as the use of four drawing-rollers in connection with each die insures absolute smoothness of working at all times. It will of course be apparent that the block must be placed at the corner of the machine diagonally opposite to the reel-that is, in the present instance, the front left-hand corner of the machine. The drawing of the wire through the last die is performed by the block alone. It will of course be understood that the oiling-rollers are arranged upon shaft 7 in such position that the wire will pass over one of these rollers just before it passes into each of the dies.

Having thus described my invention, I claim- 1. In a machine of the class described, the combination, with a longitudinal trough and oilingrollers therein, of series of vertical drawing-rollers 011 opposite sides of the machine and a series of dies arranged between the opposite series of drawing-rollers, whereby the operations of oiling and drawing are performed transversely of the machine.

2. In a machine of the class described, the combination, with a series of longitudinal dies, of vertical drawing-rollers on opposite sides of the machine, said rollers being so arranged that the right face of each roller in one series is in line with the left face of the corresponding roller in the opposite series, so that the wire may be drawn straight across the machine transversely, but without deflection of the wire save by the drawing-rollers.

3. In a machine of the class described, a series of longitudinal dies, in combination with series of drawing-rollers on opposite sides of the machine, two rollers on each side of the machine acting to draw the wire through each die, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
