MACHINE FOR FORMING CHECK-ROWER WIRE.

SPECIFICATION forming part of Letters Patent No. 314,106 dated March 17, 1885.

Application filed October .27, 1883. (No model.)

1'0 all whom it may concern.-

Be it known that I, GEORGE W. CAYWOOD, a citizen of the United States, residing in Joliet, county of WVill, and State of Illinois, 5 have invented certain new and useful Improvements in Machines for Forming Check- Row Wire, of which the following is a specification.

I My invention relates more particularly to im'provementsin machines for making checkrower wire for which United States Letters Patent,'No. 291,584, were granted to George B. Durkee on the 8th day of January, 1884, and assigned to the J oliet Wire Check Bower Gompany, to which said company the invention embodied in this application has been assigned by me.

The object of my invention is to provide the machine with novel means for guiding the end of the wire fed forward by the feedcarriage under the mandrel upon which the loops are made, whereby while one end of the wire at the point where it has been severed by the cutter at one side of the mandrel shall lie upon the mandrel, the other opposing'terminal shall be accurately guided under the mandrel, for the purpose set forth in the said application.

A further object is to provide a gage mech- 0 anism which shall allow the wire to be drawn through the machine after the formation of each knot or check to a certain extent only, whereby the checks shall be formed at regular intervals along the wire; also to provide novel 5 means for guiding one end of the wire under the mandrel after the wire has been cut and while the feed-carriage is beingadvauced; also to provide, in combination with the vibratory throw-lever situated at the delivery end of the 0 machine, an intermittiugly-operating clampthe machine by the throw-lever, whereby when a check reaches a certain part of the gage mechanism the movement of the wire shall be arrested, all as hereinafter described and claimed, and illustrated in the annexed drawings, in which Figure 1 is a top or plan view of the machine constructed as in said prior application with the addition of the improvements here- 63 inafter set forth. Fig. 2 is a perspective view ofa portion of the said machine, and shows my improved mechanism forguiding one part of the wire under the mandrel after the cut has been made. Fig. 3 is asection taken trans- 6 verse'ly through a portion of the end of the machine, said view showing the table-support, in dotted lines and illustrating means employed for clamping and holding the wire at the delivery endof the machine during the V back throw of the throw'lever. Fig. 4 is a detail side elevation of the delivery-end portion of the machine, and shows a gage mechanism for catching and holding the wire at a pointjust in advance of a knot or check during the cutting, looping, and coiling operations, or during so many of such operations as may be required. Fig. 5 is afperspective View of the forked end of the gage-lever, shown in Fig. 4 as adapted to catch the wire at one end of the knot or check. a

I have hereinbefore observed that the devices constituting the subject-mattcr of this application are applied to a machine constructed and operating upon the principle of 85, y the machine embraced in another patent. In order, therefore, to impart a clear understanding of my present invention, I shall proceed to incorporate a brief description of the construction and operation of the machine dc o. scribed at length in'said former patent, and in the present description of the machine I shall use for reference the same capital letters and numbers as are employed in the former patent to indicate corresponding parts, and denote the novel members by small letters, it I beingunderstood that thespecification and drawings of said former patent will furnish a comprehensive description and illustration of all of the details of the machine, excepting red those that form the subject of this case.

The letter A indicates the bed or'table of the main frame of the machine, and the nu merals 1 2 3 4 5 respectively refer to the wheels provided with cam-grooves and in part with mutilated gears, for the purpose of intermittingly actuating the various members of the machine at the proper moments, as fully set forth in said prior patent.

The wire 10, shown passing through the machine in the plan view Fig. 1, is first severed into two parts at a point between the mandrel D and the combined guide and rotary coiler E by means of a vibratory cutting mechanism, B, which moves forward and severs the wire and then moves back out of the way. After the wire has been thus cut, one part of the wire remains resting upon the mandrel and the feed-carriage O advances, so as to pass the end of the remaining part of the wire under the mandrel, in order to allow the two parts to be crossed by means of a subsequent forward movement of the mandrel and bar, carrying the mandrel in a direction at right angles to the line of feed.

In said former application the means for gripping the wire on the feed-carriage when the latter was movedforward, and for releasing the wire when the carriage was retracted, consisted of two spring-controlled jaws, 23, pivoted upon the carriage and limited in their movement in one direction by means of stops. Other suitable means for such purpose could, however, be employed, and no claim is made to such in this application.

The first feature of my invention relates to means for guiding under the mandrel the forward end ofthat part of the wire carried by the iced-carriage when the latter is advanced and the wire fed forward through the combined guide and coiler E. For such purpose I provide a vibratory guide,f, Fig. 2, consisting of an arm pivotally suspended from a standard, f, supported upon the block or support 28,

- through which the horizontal rack-bar 27, carrying mandrel D, and a bar, 93, carrying the stripper I, work. This arm is provided at its fwmnlower end with anotch or a pair of fiat fingers,

f set at such angle that when the arm is swung forward the free end of that part of the wire fed forward by the feed-carriage shall be caught between the fingers, which, when in or substantially in their lowest position, shall de press the end of the wire sufficiently to guide it under the mandrel as the wire is fed forward. This vibratory guide f is operated from a cam projection, g, on the wheel 2, when said cam projection strikes the cranked end of a rock-shaft, 9, supported in suitable bearings on the main frame and provided at one end with an upright arm, 9", which connects by a link, 9 with the vibratory guides. The cam projection on the wheel is timed to operate this guide-actuating mechanism after the wire has been severed by the cut-ting mechanism, so as to swing the guide forward and to liberate the crank-arm of such mechanism after the wire has been guided under the mandrel, so as to allow any suitable weight or spring attached to an arm, 9, on the rock-shaft g, to reversely operate such mechanism, and thereby swing back the guide. After this opera tion, the mandrel advances and the shoulder on the bar carrying the mandrel pushes the ends of the wire to one side, so as to cross them. The rotaryloopcr F is then brought into action, and by a rotary movement bends the ends of the wire into a pair of connected loops. The feed-carriage and the mandrel then move back to their first positions, during which said retraction on the part of the mandrel the looper F advances, whereby the looped ends of the wire held upon the mandrel between the looper and the bar carrying the mandrel are brought into the line of feed. The two carriages 4.6 and 76, respectively carrying the rotary coilers E and G, also ad vance simultaneously toward each other, and when. brought up to the work and in the proper position to engage the terminals of the wire back of the loops rotate in reverse directions, so as to coil the wire upon itself back of the loops, and thereby form the checks or shoulders. After the completion of these checks or shoulders and the rotation of the coilers has ceased, the carriages carrying the coilers move apart and recedc to their first positions. \Vhen the carriage carrying the coiler G reaches the limit of its back move ment, part 84 of the clutch carried by said carriage engages the permanently-located clutch-section 85, so that when the clutch is rotated the loosering-gear 78, engaging the sliding-jaws 62 63 of the coiler G, will, through the medium of certain connections set forth in the former application, cause said jaws to open, and thereby allow the knotted or check portion of the wire to be drawn between the jaws and through the machine by means of the vibratory throw-lever,which, as set forth in said prior application, will be located beyond the delivery end of the machine and actuated from wheel 5 by mechanism so timed that after the jaws of coiler G have been opened the throw-lever shall swing away from the machine, and in so doing an tomatically grip the wire and draw the same forward, and afterward release the wire and swing back toward the machine in position to again grip and draw forward the wire after the next operation of the machine. Thejaws of coiler G are automatically closed after the wire has been thus drawn through the ma-' chine, after which the operation of forming a check is repeated.

In order to effectively hold the wire during the several steps or operations prior to drawing it through the machine, I provide at the delivery end of the latter a clamp, which, after the wire has been drawn forward to the required extent by the throw-lever shall grip the wire and thereby prevent it from being pushed backby the throw-lever when the latter, after releasing its hold on the wire,is moving back to get a newhold on the wire, so that at its next forward movement it can again too IIC

draw forward the wire. The clamp also serves to hold the wire during the cutting, looping, and coiling operations, and the back movements of the carriages. This clamp is simply composed of a slidable bar or jaw, h, pivotally connected with a vibrating lever, h, supported at one end of the machine and provided on its lower arm with a stud or roller, It, held in the path of acam projection, h, on wheel 5 by means of a spring, h, said cam projection being timed to actuate the vibratory arm after the throw-lever has been swung forward, and to thereby cause the jaw h to slide forward and hold the vvire against one of the walls of a guide-recess, 71?, through which the wire passes. This guide-recess is conveniently formed by a metalbox or casting, h, secured upon the table and provided with a bearing for the slidable jaw.

The duration of the clamping action of the jaw'upon the wire is of course limited to the length of the cam projection, which can be varied as may be deemed expedient.

In the machine embraced in the said prior application, the length of wire drawn through the machine by the throw-lever, and consequently the distance between the checks,is determined by the extent of throw of the said throw-lever. In order to, however, more accurately regulate the distance of the checks from each other, and to insure with more eer tainty a determinate length of wire being drawn through the machine after the formation of each knot or check, I have provided a vibratory gage-lever, i, pivotally supported at one end (at the delivery end of the machine) and provided at its free or outer end with a fork or pair of fingers, 6", adapted to embrace the wire when the lever is swung down into substantially a horizontal position. This gagelever is raised and lowered by means of a pitman, 7:, provided at its lower end with a roller, Z, which bears upon a camfaced wheel, m, that is arranged and adapted to lift the pitman at the proper moment in order to raise and free the gage-lever from the wire, and to allow the pitman and consequently the gage-lever to drop at the required time, so that the fork of the latter shall ongage the wire that is to be drawnforward by the throw-lever. When, therefore, the throwlever draws the wire forward, it will at the proper moment be arrested by reason of the check coming in contact with the forked end of the gage-lever, as in Fig. 4, whereby the wire cannot be drawn to any further extent until the gage-lever has been again raised. The forked end of the gage-lever is made adjustable, so as to regulate the distances between the checks, and to such end the lever can be composed of two parts having perforations n, through which screws or bolts can be passed for the purpose of securing said parts together after the outer part carrying the fork has been properly adjusted upon the inner part of the lever.

I In said Fig. 4, the numeral 56 denotes the inclined shaft carrying two bevel-gears, 57, the upper one of which is provided for engaging a gear (not herein shown) as a means for operating the clutch mechanism while the lower bevel-gear engages a bevelgear, 55, fixed on a shaft carrying a pinion, 54, which is at intervals operated by a mutilated gear on wheel 5; also, 106 denotes the pitman employed for operating the throw-lever, and 108 the crank connected with said pitman and fixed upon a shaft carrying a gear, 105, cugaging a gear, 104, that is in turn fixed on a shaft carrying a pinion that is driven from said wheel.

It is understood that my improvements can be used on a machine constructed as shown in the drawings of the before'mentioned patent, or upon a machine adapted to perform the functions therein set forthin the specification in such case.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. In a machine for forming check-rower wire, in which the wire is severed at one side of a mandrel and one of the parts of the wire afterward fed forward, a vibratory guide arranged to engage and guide said part of the wire that is being fed forward by the carriage under the mandrel and then to release the wire, substantially as and for the purpose described.

2. The vibratory guide f, having its lower end adapted to engage and guide the wire, in combination with means for automatically vibrating said guide at the-proper moments, whereby results hereinbefore described in a machine for forming check-rower wire are attained, substantially as described.

3.

i. In a machine for forming check-rower wire, in which the wire is drawn through the machine after the formation of each check or knot, a gage mechanism and means for operating it independently of the device for draw- I engage the wire and prevent the passage of a check in the latter past the engaging part of said lever, substantially as and for the purpose described.

6. The vibratory gage-lever pivoted at one end of a machine for forming check-rower wire and having at one end a fork for engaging the wire, substantially as described.

7. The combination, in a machine for forming check-rower wire, of the vibratory gagelever, with means, substantially as described, for bringing said lever into engagement with the wire after a check has been formed, substantially as set forth.

8. The combination, in a machine for forming check-rower wire, of the vibratory gagelever with a pitman pivoted to said lever and operated by a cam-faced wheel, substantially in the manner and for the purpose described.
