Similar numerals and letters of reference indicate corresponding parts in the several ligures.

Referring to the drawings, 1 designates the frame of the machine, in Which is journaled the main driving-shaft .2, the latter having secured to it in any suitable manner a crank- Wheel 3, which has pivotally connected with it near its periphery one end of a link 4,-so that the rotation of the shaft 2, and consequently that of the wheel 3, will impart an oscillating motion tosaid link, and the latter Will thereby rock an yarm with which the other end of the link 4 is pivotally connected, as at 6, said end being adjustable relatively to the shaft 7, suitably journaled in the frame A and on which said arm is loosely mounted. (See more particularly in Fig. 5.)

The arm 5 is provided with lateral `extensions 8, (see Figs. 5, 6, and 7,) which carry Ithe spring-actuated dogs 9, which engage with the teeth of a ratchet-Wheel .10, secured to the shaft 7, so as to impart an intermittent rotary motion to said wheel, and consequently to the gear- Wheels 14 and 14, and the feedrollers 11 and 11X, Which draw the Wire 12 to be formed into staples, from a reel13 or other source of supply, which reel in the present case is mounted upon the shaft 8l, Which is suitablysupported in abracket secured to the upper part of the frame 1.

The feed-rollers 11 and 1l are secured to the gear -Wheels 14 and 14X, respectively, which mesh with each other, so as to cause said feed-rollers to rotate in the proper direction, as indicated by the arrows a and h in Fig. 5.

The shaft 15, on which is mounted the feedroller 11, is eccentrically connected with the disk 15X, so that said roller may be brought nearer to or farther from the roller 11 in order that the space between said rollers may be adj usted relatively to different thicknesses of Wire and also to flatten a Wire, if sodesired. The portion or disk lxwhichhas the shaft 15 secured thereto is-loosely mounted in the frame 1, so as to be rotated and permit the adjustment hereinbefore described.

The shaft 15 is held in an adjusted position by a set-screw 16, Which passes through a portion of the frame 1 and abuts against a stem 17, which is secured to and projects Fig. 43 repr *froml the disk liiwhen the shaft 15 is eccentricallymountcd, ashas been stated.

Pivoted to the frame 1 by an axis 18X is an adjustable guide 18, which directs the Wire 12 from the re'el 13 to the feed- rollers 11 and 11 and is made adjustable to the said rollers, so as to prevent kinking of the Wire When the same is being drawn. from the reel by said feed-rollers, said guide 18 being held in an adjusted position by a clamping-screw 19,

which passes through a slot 20 in said guide into the frame 1.

Firmly secured to the frame 1 is an anxiliary guide 21, which directs the Wire 12 to the cutting and staple-forming devices to be hereinafter described.

Pivoted to the crank-Wheel 3 on the stud 3X, on Which the link 4 is mounted, is a link 22, which is also pivoted to a lever 23, which latter is pivoted, as at 23X, to the frame 1, and is connected with a vertical sliding bar 24, so as to impart a rising-and-falling motion to the latter, for a purpose to be hereinafter described.

rlhe bar 24 is provided with a block 25, formed with a lip 26, which is adapted to enter a groove-27 (see Figs. 5, 8, and 16) in the wire-cutter 28, so as to cause said cutter to krise and fallV with the bar 24, to which said cutter is secured, said bar 24 being guided in the frame 1.

Pivoted to the Wheel 3 on the same stud With ythe link 22 and lever 23 is a link 29, Which is also connected with a sliding bar 30 and imparts a rising-and-fal-ling motion to the'same, said bar 30 being guided Within a channel 3l (see Fig. `40) in the rising-and-falling bar 24, the lobject of said bar 30' being hereinafter described.

Loosely mounted on the drivin g-shaft 2 is a driving-pulley 32, provided With one member 33 of a clutch mechanism, said member rotating With the pulley 32, so that when the member 33 is caused to engage with the remaining member 34 of the clutch mechanism said member 34, Which i`s secured to the shaft 2, Will cause said shaft to rotate, and consequently impart motion to the several parts of the machine.

Secured to the shaft 2 is an eccentric 35,

Which imparts an up-and-down motion to a rod 36, (see Fig. 2,) Which is connected with an elbow-lever 37, Which is pivoted to the frame of the machine, and is connected by a rod 38 and sleeve 40 With an elbow-lever 39, (see Figs. 2 and 44,) so that the rotation of the eccentric Willcause motions to be imparted to the elbow-lever 39, the latter being mounted on the bar 48, to be hereinafter referred tO.- The rod 38 has the end which enters the sleeve 40 screw-threaded, so that by properly rotating said rod 38 the distance between the points d `and e (see Fig. 2) may be brought closer together or moved farther apart, as required, for the purpose of an adjustment.

Secured to the `bar 24are plates 41`and 42,

IIO

(see Figs. 19, 20, 21, 2 2S, 30, 31, 40, and 41,) whose inner sides are provided with grooves 43 and 44, respectively, to receive the legs 45 and retain them in position. within said plates previous to being driven into an article 2 to be stapled or stitched.

Pivoted to a lug 1X on the frame 1 is a springactuated arm 46, (see Figs. 5, 20, 24, and 39,) to which is secured an anvil 47, on which the wire, .after being cut,'is bent into a staple, as will be hereinafter described, and thereby formed.

Loosely fitted in the frame l is an adjustable bar 48, (see Figs. 1, 2, 3, and 45,) which is provided with a device for clenching the staples after the same have been driven through an article 2X to be stitched, the saine consisting of a plate 49, provided with 'dan ges 50, and a cross-bar 51, (see Figs. 9,41, and 43,) it being noticed that a space 52 exists between said plate 49 and bar 5l., as clearly shown in Fig.

Pivoted to the plate 49 are plates 53, whose upper faces are formed with grooves 54, (see more particularly Figs. 12 and 13,) which receive the legs of the staple when the said legs are being clenched, as clearly shown in Figs. 34 and 35, and thereby retain said legs in position on the plates 53.

Fitted between the danges 50 is asliding head 55, which is secured to a bar 56, which latter is guided in the bar 48 and rests on the upper limb of the elbow-lever 39, (see Fig.

44,) so that said bar 56 may be raised by the latter when the same-is actuated by the eccentric 35 and connected parts, and consequently operate the head 55, which has pivoted to it the links 57, which are also pivoted to the plates 5a, so as to impart a partial rotary motion to the latter and thereby clench the legs of the stapleafter the same have penetrated the article 2 to be stitched. (See Figs. 34 and 35.)

Referring to Fig. 3, 5S designates a lever, which is mounted on the frame 1 and provided with a slot 59 to receive a stud 60 on the bar 48, so that when said lever 58 is either raised or lowered a similar motion will be imparted by the same to said bar 48, so that the distance between the upper edge of the clenching device carried by the same andthe under side of a drivin gplate 61,`which bears against a staple when the same is being driven into an article to be stitched,1nay be adjusted relatively to the 'thickness of the article 2 to be stitched, it being noticed, as in Fig. 6, that the driving-plate 61 is secured to the bar 30, so that 'when either a rising or a falling inotion is imparted to said bar, as hereinbcfore described,a similar motion will be transmitted to said driving-plate 61, so that when the lat- .ter is'in its lowermost position it has driven 1 by a plate G6, secured to said frame.

either up or down with the bar 4S when the same is raised or lowered for the purpose of adjustment relatively to the thickness of the article 2X to be stitched, it being noticed that the upper edge of said table is on aline with the upper edge of the clenching device, as clearly shown in Figs. 1 and 2. The bar 4S is held in an adjusted position by a clampingscrew 62X. (See Figs. 1 and 2.)

Pivoted to the bar 24 is a spring-actuated arm 63, which is provided with a wedgeshaped block 64, which occupies for a time the space between the legs 45 of a staple to prevent said legs 45 from bending inwardly when the sanne are penetrating the article 2 to be stitched, (see Figs. 6, 29, 32, 33, 36, 37, and 38,) the said block 64 being formed with recesses 65, which prevent any possibility of the legs 45 of a staple from striking the upper face of said block and which act as devlectors to direct said legs to the sides of the block 64 should the space between the points of said legs be less than the width of the block, as shown in dotted lines in Fig. 32.

The bar 24 is held in position in the frame more particularly Figs. 1, 2, and 6.)

Bearing against the pivoted arm 46 are lingers 67, (see Figs. 5 and 39,) which project from ahead 67X, guided on a rod 68, encircled by a spring 69, which normally keeps said fingers in the position shown in Fig. 39, so that the staple carried by the anvil 47 on said arm 46 will be brought by the saine in a line with the grooves 43 and 44 in the plates 4l and 42, (see more particularly Figs. 2 and 39,) for a purpose t0 be hereinafter described. The force exerted by the spring 69 on the fingers 67rnay be regulated by a nut 76 on the rod 63. v

Pivoted to the frame 1 is a treadle 71, which is connectedvin the present instance by a rod 72 with an elbow-lever 7 3, which is pivoted to the frame l and operates the member 34 of the clutch mechanism so as to either start or stop the machine.

The cutter 2S (see Fig. 5) is guided on a plate 74, which may be moved in a horizontal direction on the frame 1 for the purpose of its adjustment relatively to the length ot' the wire to be cut, said plate being held in position by means of a cla1nping-screw 75. On the frame 1 is an index 76, the saine being adjacent to the plate 74, which is graduated for adj usti-ng the length of wire to be cut off. On the link 4 is an index 77, which is adjacent to graduations 5 on the arm 5 for setting `.said link in order to adjust the throw ofsaid arm. The pivot 6 consists of the screw 7S and nut 79, the lat-terbeing provided with a handle 79X for convenience of rotating said nut.

8O designates a driving-belt for imparting motion to the pulley The lower end of one side of the cutter (see (See- IOO IIO

S2, which when said cutter is lowered is on the plate 74.

adapted to contact with the wire and force the same rearwardly for purposes to be hereinafter explained. On the plates 41 and 42 are shoulders 84, whose faces are adapted to come in contact with the ends 85 of the wire, as shown in Fig. 2l.. The swinging anvil 47 is providedy with a groove 54 for the end of the wire 12 previous to its being eut. On the plates 41 and 42 are the projections 86, and on the arm 46 are the projections 87. On the bar 30 is an inclined face 91X, the same being adapted to Contact with the projection 87 on the arm 4G, as will be hereinafter explained. The said critter 28 is also provided with a second inclined face 82X, which may be used in place of the inclined face 82 when the latter becomes worn out, (see Fig. 16,) it being evident that in such case the cutter must be reversed.

83 designates a groovein the auxiliary guide 18 for the location of the wire 12.

On the sides of the anvil 4G are the projections 88, (see Figs. 20,24, 39, and 40,) against which a portion of the legs of a staple bears, so that the same cannot slip ott said anvil when the latter is moving from the position shown in Fig. 2O to that shown infFig. 39.

On the projection 86 is a tooth 89, (see Figs.

28 and 39,) the same serving as an additional means for retaining the staple within the grooves 43 and 44, and on the frame 1 is a projection 90, which projection, in connec tion with the lever 58, holds the article to be stitched in position, as afterward explained.

An adjustable spring 91 bears against the arm 63. f l

The operation is as follows: The reel 13, which is provided with any suitable form of tension device, is placed in position on the frame 1, and the end 12 of the wire from said reel is inserted by hand in the guide 18, and the point of said wire is then brought between the feed- rollers 11 and 11 and then inserted in the auxiliary guide 21, as clearly shown in Figs. 1 and 5. The size of the staples having been decided upon, the next step is to adjust certain parts of the machine relatively to the same, the staples in the present instance being of the largest size made by the machine. The plate 74, which also serves as a gage, is moved nearer to or farther from the lanvil 47, according to the required length of the wire to be cut and formed into a staple, the desired length of the wire being indicated by the grad nations on said gage when a predetermined number on the gage is made to register with the index 7 6 on the frame 1. YV hen the plate 74 andl consequently the cutter 28, which slides thereon, have been adjusted relatively to the length of the wire to be eut, said plate is then secured in its adjusted position by the clamping-screw 75. The link 4 is then adjusted on the arm 5, so that the index 77 on the former will register with the number on the arm 5 at 5X corresponding to that taken on the gage The link 4 is then secured in position by the screw 78 and nut 7 9 ofthe pivot (l, it being evident that the length of the wire as fed by the rollers 11 and 11X will be longer or shorter, according tothe relative positions of the throw of the arm 5. A portion of the article 2 to be stitched is then placed between the lever 58 and a projection 90 on the frame 1. (See dotted lines in Fig. 3.) The lever 58 is then raised by hand and carries with it the bar 48 and connected parts until said lever 58 comes in contact with said article 2X, which, occupying the space between it and the projection 90, prevents said lever from being further raised. cause the space between the upper edge ot the clenching device and the under side of the driving-plate 61 when in its lowermost position to be separated a distance equal to the thickness of the article 2X to be stitched. Vhen the bar 48 is in its adjusted position, it is held in place on the fraine'l by tightening the screw 62; The slot 59 in the lever 58 is a trifle wider than the diameter of the pin GO, which projects from the bar 48 and enters the same. The object of this is to permit the lever 58 to drop a trilie when the same is let go. By this means the article 2X may be readily removed from between said lever 58 and theprojeetion 90. Power is imparted to the pulley 32 bythe driving-belt or other suitable means, and the treadle 71 is depressed and, owing to its connection with the clutch mechanism hereinbel'ore de- This will,

IOO

scribed, will cause the members 33 and 34 to f interlock, and the shaft 2 will consequently be rotated and will consequently impart motion to the wheel 3 and eccentric 35 thereon. The wheel 3 in rotating will impart a rocking motion to the arm 5, due to the link 4, whereby a similar `motion will be imparted to the extensions 8 of said arm, whereby the pawls 9 thereon will rotate the wheel 10, thus imparting intermittent rotary motion to the shaft 7 and also to the gear-wheel 14 and feed-roller 11X,secured thereto,the gearwheel 14 and the feed-roller 11 thus feeding the required length of wire to be formed into a shape through said rollers, it being evident that the ratchet-wheel10, shaft 7, gear-wheels 14 and 14X, and feed- rollers 11 and 11 are at rest when the arm 5 is moving backward in order that the dogs 9 thereon may again engage the teeth of the ratchet-wheel 10 for evident purposes. If the wire should kink in the process of feeding, the trouble can be easily remedied by properly adjusting the guide 18, as has been stated. )Vhen the desired length of wire to be formed into a staple has been fed by the rollers 11 and 11X, the bar 24 is lowered by the rotation of the wheel 3, due to the link 22, the lever 23, and the bar 24. The bar 24, as hereinbefore stated, has connected with it the cutter 28, so that when said bar is lowered the cutter will likewise be lowered, and in its descent will come in contact with the section of the wire 12 in its path and cut the same, it being evi- IIO dent that said cutter occupied originally a position. above the wire 12, as clearly shown in Fig. 5, in which the parts that operate the cutter are removed, so as to illustrate more clearly the parts that are behind them, the position of the cutter 2S on the bar 24 being shown in dotted linesV in Figs. 3 and 25. The bar 24 and consequently the cutter 23 thereon continue to descend after the wire has been cut. The beveled or inclined face S2 on said cutter is brought in contact with the wire 12 in its path and is forced by said inclined face behind the cutter, so as to permit the wire 12 to advance when fed by the rollers 11 and 11X, as the feeding of said wire for a subsequent staple takes place before the cutter 28 ascends. If it were not for the inclined face 32, the end of the wire 12 continuous of the wire from the reel 13 would abut against said cutter and cause said end of wire to curl or bend and thereby produce bad results.

AThe action of the inclined face32 on the end of the wire above referred to is clearly ment the inclined face 32 cornes in cont-act with the wire 12, as shown at a: in said Fig. 1S, and said wire will be moved in the direction of the arrow 7L 4by the further descent of the cutter 28. Then the cutter 2S has been lowered to its full extent, the end of the wire l2 which is continuous of the wire in the reel13 will be caused to occupy a position lin the rear of the cutter 23, as shown at y, it

having been moved by the inclined face 82 into this position Jfrom its original one shown in dotted lines at By this -means it will be seen that there can be no possibility ot the point of the Wire 12 striking the cutter 23 when said wire is being fed.

Referring now to Fig. 17, when the end of the wire 1.2 has been brought into the position shown at y in Fig. 15:' said wire iscaused to occupy the groove S3 in the auxiliary guide 21, the depth of said groove being sufficient to permit the wire 12 to occupy the same when said wire has been moved laterally from to to y in Fig. 18. The end of the wire 12 previous to being cut occupies a groove d4 in. the swinging anvil 47, (see Figs. 5, 17, 20, 24, and 40,) said wire having been fed and guided into this position by the rollers 11 and 11X and guides 12 and- 1S, respectively. The bar 24, which was in its elevated position, is now lowered, owing to its link connection with the Wheel 3, and the plates 4l and 42, secured to said bar, will, as is evident, also be lowered. Said plates in their descent will cause the shoulders 84 on said plates to comein contact with the ends 85 of the wire in the anvil 47. (See more particularly 2l.) The further descent of said deepest portions of the grooves 43.

plates will bend the ends S5 of the wire in the anvil 47, and thereby forni the legs 45 of a staple. (See Fig. 23.) Then the bar 24 hasreached its lowermost point, the projections SG on the plates 41 and 42, which were in contact with the projections S7 on the arm 46, (see Figs. 5. and 20,) no longer contact therewith, thus permitting the arm 4G and anvil 47 connected thereto, and which carries a iinished staple, to be moved from the position shown in Fig. 2O to that shown in Fig. 39, the motion being imparted to said arm 46 by the lingers (i7, which bear against the same, due to the influence of the spring G0; Then the anvil 47 is in the position shown in Fig. 39, the staple thereon is brought by the saine on a line with the upper and (See also Figg23.) The object in making the upper portions of said grooves 43 deeper than the 'lower ones is to permit the staple to spring off the anvil 47 and enter said grooves 43, it

being evident that the legs of a staple naturally tend to separate a trifle after iirst being bent into position. The legs when in the anvil are prevented from yielding to this tendency by their being in contact with the sides of the anvil 47 and the inner walls of the projections S6 on the plates 41 and 42, but slips ott said anvil 47 when the same has been moved away from said projections S6, as clearly shown in Fig. 39. The bar 30 and consequently the driving-plate 61 thereon are now lowered by the action of the wheel 3 and connected parts, it being noticed that the staple when brought into the grooves 43 and 44, as hereinbefore described, occupies a position in a plane directly below said driving-plate G1. (See Fig. 22.) The driving-plate 61 in its downward movement comes in contact with the staple and drives the saine through the article to be stitched. Then the driving-plate 6l first comes in contact with a staple,the space between the limbs of the saine is occupied by a portion of the block 64, (see Figs. 33 and 36,) said block preventing the bending inwardly of the legs 45 of the staple when the saine is being driven, as hereinbefore described. The driving-plate 61 in farther descending carries with it the staple and drives the same into the article 2 to be stitched, (see Fig. 37,) the portion of a staple resting on the inclined face of the block 64 gradually moving the same, owing to said inclination in the present case to the right, and causing said block to gradually leave the space between the legs 45 of a staple, as clearly shown in Fig. 37. A spring 91, (see Fig. 26,) which normally keeps said arm 63 in the position shown inv Fig. 27, yields under the inliuence of the lower end of the descending bar 30 and thus permits the block 64 to be removed from the space between the limbs 45 of a staple. Then the bar 30 is up, the spring 91 restores said arm to its normal position, said spring being sustained on the rod 91XX while passing freely through the arm 63 and is secured to the bar IOO IIO

24s, the tension of said spring being regulated by the nut QIXXX on said rod. Vhen the drivin g-plate Gl has completed its downward movement, the block (Si is entirely removed from the staple'(see Fig. 3S) and the legs of the latter have fully penetrated the article to be stitched.

Vhen a staple has been fully driven into an article to be stitched, a portion of its legs come in contact with the plates 53. (See Fig. 34.)` The eccentric 35 and connected parts now raise the bar 5G, which carries with it the head 55, and owing to its link connections with the plates 53 moves the latter on their pivots, so as to occupy the position shown in Fig. 35, thereby clenching the legs of a staple on the article, as clearly shown in said Fig. 35. The inclined face 91X on the bar 30 will contact with the projection S7 on the arm 4G when said bar 30 is lowered and overcome the pressure of the spring G9, which locates and temporarily retains said arm in the position shown in Fig. 89 and thereby causes the anvil 4:7 on said arm to be restored to its normal position in order to receive another piece of wire to be formed into a staple.. (See Fig. 20.)

The operation hereinbefore described is repeated in the formation, driving, and clenching of subsequent staples.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a wire-stitching machine, a frame, a driving-shaft with a crank-wheel thereon, feeding-rollers mounted on said frame, a rocking arm having a link connection with said crank-wheel, dogs mounted on said arm and engaging a ratchet-wheel on the shaft thereof, the adjustable guide I8 pivoted to said frame and leading to said feeding-rollers, and having the slot 2O therein, the clamping-screw 19, and a reciprocating cutter.
