WlRE-NETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 441,457, dated November 25, 1890. pp cation filed September 5,1890. eel-a1 No. 364,030. (No model.)

To all whom it may concern:

Be it known that I, HENRY B. MORRIS, a citizen of the United States, residing at Geneva, in the county of Ontario and State of New York, have invented certain new and useful Improvements in Machines for the Manufacture of ire-Netting, of which the following is 'a specification.

This invention relates chiefly to that class of wire-netting machines adapted to manufacture hexagonal mesh or poultry netting.

The object of my invention is to increase the speed and output of machines of this class and at the same time to construct and operate the machine at as small a cost as possible and to renderit entirely reliable. Those machines which revolve pairs of cops around each other are defective because small cops only can be carried by the machine and must be constantly renewed. Machines which involve a double twist between each mesh lose time in reversing, as do also those machines in which the twisters are shifted laterally in forming the meshes. In carrying out my invention I provide a series of drivers, one half of which revolve while the other half remain stationary. Between the drivers are interposed twisters, which by reason of their peculiar shape will hereinafter be called lunes. I call the twisters lunes because in crosssection they correspond to the definition of a geometrical lune, which is afigure formed by two arcs which inclose a space. Each alternate lune carries a wire cop and the others each carry a guide for a strand of wire drawn from a reel below the bed-plate of the machine. Each driver is recessed on opposite sides to receive a pair of lunes, and each driver, with its pair of lunes, is circular in cross-section. All the lunes. except those at the ends of the series, are completely inclosed in the adjoining recesses of the drivers, so that the interposed lune may be made to re- Volve with either of the adjacent drivers. Mechanism is provided for revolving the drivers and the lunes and for holding one set of drivers stationary while the other set is revolving. As the netting is completed it is drawn overyrollers and finally wound up on a roller driven at thereqiiired speed to draw much of a wire-netting machine embodying all my improvements in the best way now known to me as is neccessary to illustrate the sub ject-matter herein claimed. Some of these improvements, however, may be used without the others, and in machines differing in dethe wires from the twisters under suitable tentails of construction from those herein shown.

As myinvention contemplates the application of these improvements to the most highly organized machines of the present day, I do not confine myself to the details of construction and organization herein shown, but when specifying a particular construction or organization intend to include well-known equivalents therefor.

Fig. 3 is a view, partly in plan and partly in section, on the line 3 3 of Fig. 1. views illustrating the manner of twisting the wires to form hexagonal netting by my apparatus. Fig. 6 showsin detail the construction of the drivers and lunes. Fig. 7 is a View, principally in vertical central section, of one of the wire cops and its frame. cal central section of one of the guides. Fig. 9 is a detailview, in perspective, showing the connection of a guide with a lune; and Fig.

The bed-plate A is horizontally disposed and is supported on suitable standards B. The bed-plate, as shown, is hollow, having a top a, bottom a, and sides a a Circular bed-plate and are arranged in a straight line from one end of the bed-plate to the other, and these apertures intersect, the intersecting arcs forming geometrical lunes between Figs. 4 and 5 are diagram I Fig. 8 is verti- 10 is a detail view, in section. showing more clearly the formation of the lower end of a apertures O extend vertically through the them. In the apertures are mounted drivers, the construction of which is shown on an enlarged scale in Fig. 6, and these drivers have interposed between them the lunes,whicl1 are also shown in Fig. 6. Each driver is convex on two opposite sides, and on the two other sides is concave.

There are two sets of drivers D and D. They differ .only slightly in construction, as will be now described. The drivers D are provided with gear-teeth (Z on their opposite convex sides a distance above the lower ends of the drivers about equal to the length of the teeth. The concave sides of the drivers D, below the horizontal plane of the teeth d, are cut away or recessed at d for a purpose hereinafter described. The drivers D are similar to the drivers D, except that the teeth (1 extend from the bottom of the drivers upwardly, and the recesses d in the concave portions are above the plane of the teeth (1 The lun'es E may all be of the same shape, and are of such a shape as to fill completely the adjoining recesses of adjacent drivers, as

is clearly shown in Fig. 3, so that when the drivers and lunes are all in place the intersecting circles or apertures C in the bed-plate are completely filled.

The lunes E are provided with two series of gear-teeth e 6, corresponding with the teeth at and d on the driversi. e., the teeth e on one side of the lune are arranged a short distance above the lower ends of the lune, and the teeth 'eare arranged on the opposite side nearer the lower edge. If the two drivers and the three lunes (shown in Fig. 6) were assembled, the teeth e on the lunes would enter the recesses cl on opposite sides of the driver D, while the teeth 6 would coincide with the teeth (I and complete a true gear-wheel. The teeth eon the central lune, and also on the lnn'e'at the right-hand side, would extend into the recesses d of the'driver D, the teeth 6 coinciding with the teeth d on'the driverD and completing a true gear-wheel. The lunes are recessed at e to allow the rack-bars, hereinafter described, to pass without turning them. The reduced portions (2 of the lunes at their lower ends, below the teeth 6, extend into apertures c in a plate 0, secured to the underside of the bed-plate. The apertures in the bottom a of the bed-plate are slightly larger in diameter than those in the top to accommodate the projecting, gear-teeth on the drivers and lunes. The apertures in the top plate a are undercut at a the upper ends of the lunes being reduced at e and prolonged to enter these openings, their upper ends being flush with the surface of the bed-plate. Each alternate lune in the series carries a wire cop or bobbin F, and the others carry wire guides Gr. The cop and its frame are shown in detail in Fig.7. The frame is shownas consisting of abottom piecefand atop piecef, con-.

nected by side pieces The cop F is secured'to the bottom piece f, preferably by a screw-conly-projecting tubular neck f on which is mounted a friction-roller F, and above the roller is secured a head-block f perforated vertically to permit the passage of the wire as, and carrying adjacent rollers f mounted on horizontal axes. The bottom piece f is pro vided with a foot-piece f, which enters an opening or socket c in the top of the corresponding lune. A laterally-projecting pin on the foot-piece f", in connection with an shaped slot 6 in the lune, forms a bayonetjoint for connecting the cop and its frame to thelune. I also provide aspring-latch bolt f moving vertically in the bottom piece f and entering the vertical portion of the L-shaped slot e. By this means the cop-frame is secured to the lune so that it cannot move either vertically or about its axis until the spring-latch bolt is raised positively. Spring. fingers F bear on the upper end of the cop and hold it always in a true vertical position.

The guides G each consist of a spindle g, perforated vertically at its upper end and provided with ahead-block g, carrying guiderollers 9 between which the wire 1 is fed. A friction-roller g is interposed between thebottom of the block g" and a collar 9 on the spindle. Near the lower end of the spindle is secured a foot-block g, which carries a spring-latchg similar to the latch f on the cop-frame. A laterally-projecting pin g is secured to the lower tubular portion of the spindle below the foot-block g, and, in connection with the slot '6 in the top of the lune, forms a bayonet-joint. The connection between the guide G and the lune is similar to that between the cop-frame and a lune, as previously described.

The spindle is formed with a longitudinal slit 9 between the inner ends of the tubesat each end of the spindle, so that a continuous passage-way may be formed for the wire 3 hen the cop and guides are mounted, each .110

alternate lune carries a cop and the others a guide. The cops and guides are thus arranged in close proximity to each other and should they tend to lean toward each other or get out of a true vertical position the rollers'g will bear against the rollers F and prevent their interference.

The drivers D are formed with lateral apertures (Z and the drivers D" with apertures d on the opposite side. These apertures are adapted to receive the pins h 7i respectively, which extend horizontally through the sides of the bed-plate A. The pins 71 are secured to a side bar H,-connected to the bed-plate by bolts H, 011 which they are free to slide. Springs H normally hold the bar II against the side of the bed-plate. The pins h are in like manner connected to a side bar 11 which is secured and normally held against the side of the bed-plate by bolts and springs H H The bars H and H are withdrawn from the bed-plate, so as to withdraw the pins from the holes in the drivers by means of reciprocating cambars I. These bars slide in guide-grooves in 'the sides of the bed-plate and are provided with cams or inclines 11,

adapted to engage with pins t", projecting downwardly from the pin-carrying bars H and H The mechanism for operating the cam-bars is such that when the pins are withdrawn from the drivers D they will be insert-ed into the drivers D, and vice versa. The drivers and lunes are revolved by rackbars J J. The rack-bar J is mounted in the bed-plate above the rack-bar J and on the opposite side of the openings 0. The bar J is adapted to engage with the teeth e on the lunes and the teeth 61 on the drivers, while the rack-bars J are adapted to engage with the teeth 6 on the lunes and the teeth d on the drivers. The mechanism for reciprocating the rack-bars is such that while the bar J .is being operated to revolve the-drivers D and the lunes on opposite sides thereof the pins are withdrawn from the lateral apertures in said drivers, while the pins on the opposite side engage with the apertures in the drivers D to hold them stationary.

Strands of wire a: pass from the tops of the cops F and strands of wire y pass through apertures e in the lunes and through the guides G from reels X below the bed-plate. The wires are fed or drawn from the twisting mechanism over feeding and pressure-rolls L and M and onto a receiving-roll N. The main operating-shaft O is journaled in suitable bearings 0 in the main frame and carries on one end a large cog-wheel O, which meshes with a pinion O on the shaft of the driving-pulley P. On the opposite end of the driving-shaft is secured a crown-wheel Q, which meshes with a similar wheel Q, on the shaft of which are pulleys q q. A sprocketchain q extends over the pulley q and over a sprocket-pulley L on the shaft of the roller L. A cog L on the shaft of the roller L gears with a cog M on the shaft of the roller M. The receiving-roller N is driven by means of r the sprocket-chain N, passing over the pulley q and the large pulley N Theoperating-connectionsbetween the main driving-shaft and the twisting apparatus are as follows: The rack-bars J and J are con nected by means of rods R to rock-bars S, pivoted at their lower ends 3 to the main frame and carrying friction-rollers s, engaging cam-grooves in opposite sides of a large cam-wheel T, revolving with the main shaft 0. The cam-grooves are so formed and the connections are such that while the rack-bar .J is being reciprocated the bar J is stationary, and vice versa. The sliding bars I are pivotally connected with vertical rock-bars U, pivoted to brackets U on the main frame, and carrying at their lower ends friction-rollers u, engaging cam-grooves in cam-wheels V,-

drivers D are indicated as revolving and the drivers D as stationary. Wires a: and y, m and y, and x and 11 on opposite sides ofethe drivers D, are twisted together-that is, the wire y is twisted around the'wire 0c, the wire y around the wire m, and the wire g around.
