WIRE-N-ETTING MACHIN E.

SPECIFICATION forming part of Letters Patent No. 432,223, dated July 15, 1890.

Application filed I'ebruary 12, 1889. Serial No. 299,672- (No model.)

To all whom it may concern:

Be it known that I, EDWARD SAMUEL BOND, engineer and machinist, of the Crown Engine and Machine WVorks, Lower Hurst Street East, Birmingham, in the county of Warwick, England, and a subject of Great Britain, have invented certain new and useful Improvements in Machineryfor Manufacturing Wiredriving-gear or the means of operating the plates and pinions for twistingthewire. These plates have hitherto been operated in a Very clumsy and noisy manner, which has prevented the machines being driven any other than slowly, as any jerking throws the wearing parts into more or less disorder.

Now my improved machinery is very simple, and I am therefore able without risk to run the machines at, say, above twice the speed which has hitherto been possible. This is of course a most important advantage, as

netting is manufactured in a much more efj ficient manner, by reason of there being little.

or no vibration in the working of the'machi1 1e.'

Thus less capital is required to produce the work.

My improvements further consist in the use of a rack in each half of the plates instead of one in the one-half, thereby increasing the power of the pinions .for twisting stronger gages of wire and at the same time also preventing the pinions from slipping out of gear, which is an important failing with the present machines.

Another portion of my invention consists in the support of the plates by means of the stretchers being provided with flanges which receive the plates, thereby preventing them from bending in the center, also keeping them true on their edge, and by these means allowenough of the ordinary parts of a wire-netting machine to show the application of my improvements thereto.

Figure 1 is a plan of both ends of the machine, the right-hand side showing the top plates 0 and the left-hand side showing a sectional plan of the racks D, with their connections. Fig. 2 is a perspective view of the driving end of the machine with a portion of the frame-work broken away, so as to show the bevel cam-wheel A in gear with the driving bevel-wheel F, and the mode of operating the plates 0. Fig. 3 is a broken-off elevation from the rear of the machine to show the driving-shaft F and bevel-wheel I and the action of the internal cam groove (1?. Fig. 4 is anenlarged elevation of the center orworking portion of the machine broken away in the middle, but showing the twisting of the wire, one of the tubes 2 being in section. Fig. 5 is a cross-section through the last figure, also showing the tube broken away to show the coil,as hereinafter explained. Fig. 6 is an enlarged sectional plan through theplates, showing the racks and pinions.

of the connecting-rod D, hereinafter described. Fig. 8 is a plan of the attachment N of the lever M to the plates 0. Fig. 9 is a side elevation of the same. Fig. 10 is a plan of the adjustable pivoted arms 13 for operating the plates 0. Fig. 11 is a view of the ends of the plates 0, showing a modification of the method of working them.

The top and bottom plates 0, racks D, and

Fig. '7 is an elevation of the disk A and part pinions E are similar to those in the ordinary wire-netting machine and operate upon the wire in a similar manner, as shown in Figs/I and 5i. a, one half of the plates 0 slide horizontally backward and forward by means described hereinafter in the reverse direction forms the one strand of the net-tin g, the other strand 3" passing up from the spindles 3, round the roller 5, through the halves E of the bottom pinion, then up between the tubes 2, and through the halves E of the top pinions, the relative halves of the pinions being altered with regard to each other at each move of the plates (1, E being at one time opposite E, as shown at Fig. (3, and another time opposite E, and after each change both halves are revolved together by means of a.

sliding backward-and-forward mot-ion of the toothed racks D,which are operated as hereinafter described, and which engage in the teeth 6' in the pinions E and E By these means the wire is twisted and spread, merely forming the wire-netting, as shown by Fig. 4,. winch 1s drawn away as formed by means of the projections 4" upon the cylinder 4, which is mounted and revolves between the ends Y and Z of the machine.

N ow my improvements relate, first, to the operation of the plates 0, so as to obviate the use of any stops to the said plates, which I effect as follows: I mountthe disk A upon any convenient partof themachine, but preferably upon the brackets A and A which may be cast in one with the end Z of the machine.

The disk A is formed as a bevel-wheel, so as. to engage and receive its motion from the. bevel-wheel F on the main shaft F. Upon the face of the disk the internal cam or groove a is formed, which actuates the roller or studl h on the lever H, which, as it rises and falls,

slightly revolves the small shaft II in the bearings h and its, and by means of the toothed segment H engaging with the toothed seg ment K, the vertical shaft K revolves in the" bearings K and K, which are formed on the end frame Z of the machine. The cross-arms B are fixed to the bottom and top of this shaft and are connected to the upper and lower plates C by means of the link M and attachment N, (shown by Figs. 8 and 9,) thereby opcrating the plates 0 in the reverse direction to each other, as required.

To prevent the slightest spring or vibration occurring to throw the plates out of position, I provide the stops 71. and If to the lever H,

which may be adjusted to secure it at the ex tremes of the stroke, thereby locking the lever between the stops and the edge of the groove a operated with a similar effect by a double eccentric or the two eccentrics mounted uponthe shaft R, as shown in Fig. 11. To allow of the mostperfect adjustment of the plates C with regard to each other, the arrangement shown by Fig. 10 isprovided, the arms B having the slots b, in which the loose pieces I) are inserted. These pieces Z) are provided with the inclined projections N, which butt against similar inclines formed in the side of the slots b in the arms. The set-screws b are provided for adjusting the position of the loose pieces b, and Fig. 10 shows on each side of the arm the difference in the position of the pin If at the two extremes of adjustment. Further adjustment may be obtained by the arrangement shown by N, Figs. 8 and 9, which is for the purpose of attaching the link M to the plates 0, the pin 01,, to which the link Mis secured, being made to move in the slot n and is afterward firmly secured in position by the set-screws it. This arrangement is also used for the adjustment of the racks D. The racks D are operated at the reverse end of the machine and from the other side of the disk A by means of the connecting-rod D, which is connected to the vertical shaft 0 and in turn to the racks D by the armsPand smaller connecting-rods P in asimilar way to the operation of the platesC butin operating'both of the racks D backward and forward, as shown, instead of only one, as heretofore, it will readily be seen that as the half-pinions E alter their relative positions with regard to each other at each stroke of the racks,andthat the endhalves e or e ateach stroke have no corresponding half-pinions opposite to them to allow them to revolve, they cannot when in such position be actuated by the movement of the rack. The independent movement of the racks is, however, allowed by means of cutting away the two teeth of the long half-pinion e at one end and the short half-pinion e at the other end, so as to allow the racks D to move independently when these half-pinions are not able to revolve by reason of not being in the solid part of the plate, as seen by 6 Fig. 1; but as soon as thehalf-pinion e returns opposite the next half of the pinion it forms a circle in which it can and does revolve by means of the other half, which is provided with teeth and is actuated by the other rack D. I am thus enabled to work the pinions E with.

double racks, thereby obtaining increased strength for the manipulation of a thicker strand of wire; but I do not confine myself to using any particular number of racks in the upper or lower parts or this particular mode of operating the racks, in combination with the other parts of my invention. The arms P arev provided with the slots P for the further adjustment of the racks.

My improvements relate, further, to the construction of the stretchers T, for connecting the ends of the machine together, which I provide with the flange S, for the purpose of supporting the plates 0 and preventing them from bending in the center. The stretchers 'l on each side of the plates by this means form a trough, in which the plates slide, thereby enabling me to make the machines of any desired length without fear of the plates bending downward in the middle, which at the same time keeps the plates true on their edge, thereby insuring thefree and easy working of the pinions E.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In combination with a pair of reciprocating plates, a pair of racks attached to said plates and having their teeth facing each other, the rack-operating devices consisting of disk A, connecting-rod D, shaft 0, arms I,

and connecting-rods P, and a set of half-pinions arranged between the said racks to engage them, the end half-pinions e 6 being mutilated, substantially as and for the purpose set forth.

2. In wire-netting machinery, the combination of the reciprocating plates and wiretwisting pinions with connections between them,and the actuating devices for said plates,

consisting of a disk having an internal cam a a lever H, engaging therewith, a shaft H operated by said lever, and the toothed segm ents H and K, the vertical shaft K, the arms B, and the link M, connecting said shaft and plates, substantially as set forth.

3. In combination with the wire-twisting pinions of a wire-netting machine and the reciprocating plates and connecting devices whereby said pinions are operated, adj usting screws and loose blocks for regulating the position of said plates, substantially as set forth.

4:. In combination with the. wire-twisting pinions, reciprocating plates, and intervening connections forming parts of a Wire-netting machine, a link M, pin 02, slotted piece N, and screws 11 for additional adjustment of said plates, substantially as set forth.

In testimony that I claim the foregoing as my own I affix my name in the presence of two witnesses.

EDIVARD SAMUEL BOND.
