MACHINE FOR BENDING JACQUARD HOOKS.
SPECIFICATION forming part of Letters Patent No. 515,347, dated February 27, 1894.
Application filed May 15, 1893. $erial No. 474,235. (No model.)
To all whom it may concern.-
Be it known that l, RoBERnG. MANVILLE, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a new and Improved Machine for Bending Jacquard Hooks, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.
My invention relates to a machine forbending Jacquard hooks, and has for its object to provide a machine for bending these or similar articles from wire quickly and in such a manner that the resulting bent articles can be relied on always to be uniform; and to this end it consists in certain details of construction and combinations of parts which will be more specifically pointed out in the claims appended to this specification and forming a part thereof.
Heretofore it has been customary to bend Jacquard hooks by hand, first bending the hook (marked in Figure 10 of the accompanying drawings) which is carried by the lowerhook plate, then bending the wire so as to form two arms of suitable length (this bend is marked 7.0 in Fig. 10); and finally bending the hook and trimming it by a cutter or other tool so as to form a suitable hook for the upper hook plate. My hook bending machine, first bending the wire into two arms of suitable length; then, preferably when the wire is held fast by the mechanism which forms the two arms,turns one end of the wire over so as to form a smooth round hook (as w on the end of one arm, and bends the wire sharply so as to turn the end of the other arm into a hook (as 103) suitable for the upper griff hook; and then when the griff book has been properly turned, cuts or trims the end thereof so as to give it a proper inclination.
My invention is best understood as described in connection with the drawings in which is illustrated a machine constructed according to my invention and in which Fig. 1 is a front elevation of my machine. Fig. 2 is a plan view showing the various cams and operative parts in position. Fig. 3 is a side elevation looking from the left of Fig. 1. Fig. 4 is a detail of a feeding bar taken on the line cv-x of Fig. 1. Fig. 5 is a detail of the feeding device. Fig. 6 is a detail View of the tucker. Fig. 7 is an enlarged detailed view of the mechanism used to turn one of the bends on the Jacquard hook. Fig.8 is an enlarged detailed View of the mechanism used to bend the other or griff hook on aJacquard hook. Figs. 9 and 10 are detail views. Fig. 11 is a plan view of the apparatus for bending the hook to shown in operation, and Fig. 12 is a view of the cam which operates the clamping mechanism.
In bending wires to form Jacquard hooks a straight Wire as 10 Fig. 1 is bent to the form shown at w Fig. 8, the hooks to and w are respectively turned and bent, and the end of hook 10 is then trimmed so as to form a suitable griff hook.
In my machine for forming Jacquard hooks, T is a table supported on suitable standards T and having journaled to itin supporting standards as T shafts C C and a driving shaft R. The shafts C C are driven by means of gears D C on the shafts R and C respectively and bevel gears as ccconnecting the shafts C C On the shafts C C are certain cams as C C &c., which serve to actuate a series of bending and other mechanisms which form a finished Jacquard hook froma straight piece of wire. Supported on the table T by means of standards a is a support or feeding board 75 on which straight pieces of wire are placed of a suitable length; guides t serve to conduct the wires into a vertical slot or groove formed in the upright standards a which are preferably made laterally adjustable to serve for different lengths of wires. In the sides of the standards a are arranged feeding mechanisms, which,as shown,consist of two beveled plates D fitted 'in and guided in corresponding recesses in the standards (1 These plates are ICO adjusted by shifting the standards a any desired length or size of hook can be made.
The construction of the tucker A and its coacting mechanism is best shown in Fig. 6, where the tucker A is shown in perspective. On a frame F secured to the table T is fastened a plate A, behind this is the tucker A which has a recess or slot at of sufficient width to embrace and fit over the plate A, grooves as a a are arranged as shown in which the Wire fits which is to be bent. The tucker is properly guided by guides as a and is reciprocated by a link 0 which is operated by a roller Working in a pull and push cam O, which is preferably so arranged as to give a slow forward movement and a quick return so as to move the tucker A slowly when it is bending a wire and withdraw it quickly when the hook is completed.
The bending mechanism consists of several devices which will be described in detail. On a standard n secured to the table T, (as best shown in Fig.,7,) is pivoted a plate N which has a Vertical hole n formed in its front end; in said hole is secured a hollow sleeve N so that it will turn in the hole in the plate N. On the lower end of the sleeve is formed a small gear n, and below the gear at is conveniently arranged a guide wheel at in which is secureda pin n Within the sleeve N isa spindle O which is secured to apivoted lever 0 which lever is operated by a cam O to raise and lower the spindle O at proper times. The lever c has a head 0' with a slot 0 therein and is secured on the upper end of the spindle by a bolt as 0. Pivoted at m is a segmental rack M which is arranged to engage with the gear wheel at; the teeth m of this rack are eccentric to the pivotal point m, that is, the teeth at m are farther from the pivot on than are those at 721*, but by adjusting the pivot m in the slot m of the rack this eccentricity can be changed as desired. The rack M is also preferably provided with a guide at m which fits around the guide wheel n, and is operated by alink 'm pivoted to the rack and to an arm 0 which is actuated by a suitable cam 0 A frameG is arranged on the table T in front of rack M just described and carries and guides other devices which are best shown in Figs. 8 and 11. To arod H secured to the frame G is fastened a light spring h which tends to hold the lever c which is pivoted at h in a raised position. To this lever c at one end is secured a flap as h and at the other end a roller which engages a cam C which operates on occasions to depress that end of the lever which carries the flap k for a reason to be hereinafter explained. Sliding in a bevel groove g in the frame G is a rack G which is provided with teeth at g and is pivoted at G to the arm 0 which is operated by a suitable cam O to reciprocate the rack G. Secured between two journals G G6 on the face of the frame Gis a gear wheel G whose teeth g mesh with the teeth of the rack. Arranged to revolve with said gear wheel G but free to move vertically through the gear wheelGr is a spindle G this spindle has a pin 9 secured therein which fits in ahelical groove 9 formed in the lower journal G6 and the result of this construction is to rotate and reciprocate the spindle G4 when the gear wheel is rotated by the reciprocation of the rack G. To the lower end of the spindle G as best seen in Fig. 10 is adjustably secured by means of a screw as g the chuck G carrying a suitable cutter g. To the front of the frame Gr and partly covered as shown by an extension G thereof is another frame B in a slot 19 in this frame is arranged a block 0 which is reciprocated by a cam O; to this block is pivoted at b a block b which has secured to it a head I) which is normally held in the position shown in Fig. Sby a spring as 19 In the path of the head I) as it is reciprocated by the cam O is placed a bevel cam B which is adjustably secured to the frame B by a screw as B. At one side of the head I) as more clearly shown in plan in Fig. 11 is a former B which has a specially formed end 19 shaped on it corresponding to an end 2) on the head I) and behind the end b is a recess 17 and an incline I) is formed on the outside of the former as shown.
Directly within and in line with the former B I arrange a clamping block F; this block which slides in a suitable groove in the frame B is operated by an arm 0 which receives motion from a cam 0 whose contour is shown in Fig. 12, and which operates to push forward the clamping block a short distance so as to form a stop for one end of the wire when it is bent (in a manner to'be explained) then it pushes the clamping block so as to hold the end of the wire, which fits in a groove as fin the face of the clamping block F, tightly between itself and the end of former B and finally completely withdraws the clamping block. At the side of the clamping block F as shown in Fig. ll is secured a bracketf which extends a short distance in front of the block but which does not come up to the top of the block but only so high that the wire can rest on the bracket in line with the groove fin the block before it is securely held between the clamping plate and the former.
Then the wire is completely bent as desired and the clamping plate is withdrawn so far that the bracket f no longer supports the wire then the mechanism best shown in Fig. 6. comes into play to push the Wire down through the slot S in the table T where itis guided'by an incline S' into a suitable receptacle S this mechanism consists of a spindlep which is moved up and down at proper times by a lever c operated by a cam O and which carries a foot 10 which has two forks p which fit over the plate A.
The manner of operation is as follows: A number of wires of approximately suitable length are placed on the feed board if and being rolled to the front of it fall down in the slot 75 and pile up in the manner shown in Figs. 1 and 5. On setting the machine in motion the feeders D move forward and separate one wire at a time and feed it down in front of the tucker A, the ends of the wire resting in the bottom of the groove 25 an aperture i being provided as shown in Fig. 5 so that the ends of the wires can be readily pushed out of their position in the groove 6 when the wire is bent by't-he tucker. The tucker A then advances and bends the wire at w into two arms of a length governed by the position of the tucker A and plate A. The ends of the wire as they sweep around are supported on the segmental guides e e, the shorter end of the wire coming against the pin 92 in the hollow sleeve N thereupon the lever c is depressed and the pin 0 comes down on the other side of the wire, which is now held between the two pins in a manner shown in Fig. 9. The rack M is now moved by its actuating cam O in the direction of the arrow and rotates the sleeve N and the pin 71 around the pin 0' and at the same time moves the plate N slightly on its axis so that the end of the wire is turned into a neat book as 10 The pin 0 is then raised by the cam C operating through the arm 0 and this part of the operation is completed. In, the meantime the other end of the wire has been carried around in like manner and riding up the incline b of the former B it rests somewhere on the top of the former block, the flap h is now depressed and the end it of the flap pushes the end of the wire between the former B and the clamping block F, this clamping block has been removed so far forward that the bracket f has been put in a position as shown in Fig. 11 so thatthe end of the wire will not be pushed down too far and when the wire is pushed into proper position the clamping block is so moved by the cam C as to securely hold the wire. When the wire is thus securely held the head I) is moved forward first bending the wire at right angles over the end b of the former and then,when the rounded face b of the head I) strikes the cam B it operates to make a sharp hook in a manner shown in Fig. 11. The hook being formed, the head I) is withdrawn and the cutter g on the block G comes down and trims off the end of the hook the cuttings conveniently falling down in the recess 12. The cutter is moved up and away, the clamping block fully drawn back, the lever c is raised, the tucker A pulled back and the now finished hook being free the foot p is depressed and the hook is pushed through the slot S to the receptacle for finished hooks, the foot p is raised by the action of its actuating cam O and the machine is ready for another operation.
It will of course be obvious that various devices can be substituted for many of those shown, and while I have described the parts and arrangement which I deem most useful and convenient I do not wish to be considered as binding myself to the exact construction shown, and also it is obvious that man y of my present devices can be used in other connections than in a machine for bending Jacquard hooks. The bending devices are all adj ustably secured to the table T and can be arranged to form any desired size of hook.
