fo all whom it may concern.:

Be it known that I, HENRY WEBER, a citizen of the United States, residing at Chicago, in g the county of Cook and State of Illinois, have 5 invented certain new and useful Improvements in Wire-Stitching Machines, of which the following is a specication, reference being had to the accompanying drawings, in whichro Figure 1 is a side elevation of the machine.

This invention relates to'wire-stitching ma- '45 chines in which wire is fed and severed into suitable lengths for staples and the staples 5 formed and driven through book or other material which it is desired to fasten together and clinched in place.

The objects of my invention are to provide a new and improved feed mechanism for feed Fig. 12 is a detail,

ing the wire, to provide novel feed-adj usting devices, to lprovide novel means for forming the legs of the staples of uniform length, to provide novel wire-straightening devices, and to generally improve machines of the character referred to.

To accomplish these objects my linvention consists in the combinations of devices hereinafter described, and pointed out in the 6o claims. Y

In the drawings, 1.7 indicates the supporting-pillar of the machine, from which extend two goose-neck supports 18 and 19.

2O (seeFig. 8) indicates a driving-shaft, 65 which is journaled in the goose-neck 19 and carries a driving-pulley 21 upon its outer end.

22 indicates a back plate, which is secured upon the projecting end of the goose-neck 19 and is provided with a suitable opening 7o through which the driving-shaft 2O passes,

and with side pieces 2.3, forming supports ,upon which aglass plate 24 may be secured, protecting the parts, as is best shown in Fig. 2.

25 indicates a cam, which is keyed upon 75 the outer end of the driving-shaft 20, resting with its back against the surface of the back plate 22. The cam 25 has an outer cam-surface `2.6,which operates to move the Wire-feeding'device, as hereinafter described. It is 8c also provided with a cam-groove 27, which is adapted to operate the staple former and driver, as hereinafter described.

28 indicates a spool, which is rotatably mounted upon a bracket 29,.secured to the goose-neck 19.

30V indicates a pin, which'is mounted horizontally on the top of the-'bracket 29 above the spool. p

Slindicates a band of leather or other suit- 9o able material the end of which is secured upon the pin 30. The belt 31 passes around the spool a suitable distanceand is provided with'anopening 32, through which the wire' may pass, as is best shownfin Fig;- 16.

33 indicates a spiral spring of suitable tension connecting the free end of the belt 3l with the pin 30, as is best shown in Fig. V16, and operating to cause ,thev belt- 31 to `lofe'ar with proper force uponv the spool 28 as it ro- Io tates. 2

34 indicates a hollow arm secured to the back plate 22. 35 indicates a sliding rod moving horizontally in and out in said hollow arm 34, and carrying upon its outer end a curved tension-tube 36. A spiral spring operates to push the rod 35, and with it the tension-tube 36, outward, so as to cause the proper degree of tension upon the wire which passes from the spool 28 through the tension-tube 36; but as these devices are old and well known it is not necessary to describe them inv detail.

37 indicates a feed-lever, which is pivotally mounted upon the back plate 22 upon a stud 38, which carries at its upper end a roller 39, which is adapted to bear upon the outer surface of the cam 25. Aspiral spring mounted upon the stud 38 operates to force the upper end of the feed-lever 37, and with it the roller 39, toward the cam 25; but as such spring and its method of attachment and operation are old and well known in this class of machines I have not shown it in the drawings, and it will not be necessary to describe itin detail. The lower end of the feed-lever 37 is provided with a slot 40, adapted to engage with a pin upon the sliding feeder and move the same back and forth, as hereinafter described.

41 indicates a feed-adjuster, which is provided with a projecting block 42 upon its rear surface, adapted to slide horizontally in a slot 43 in the back plate 22, as is best shown in Fig. 4.

44 indicates a back piece, which is bolted to the back of the block 42 and adapted to bear against the back surface of the back plate 22 above and below the slot 43, so as to hold the feed-adjuster upon the back plate.

45 indicates a rod, which is secured to the back piece 44 and projects horizontally a suitable distance beyond the edge of the back plate and is screw-threaded upon its outer end.

46 indicates a screw-threaded tube rotatably mounted in au ear 47, secured to the back plate 22, as is best shown in Fig. 4. The tube 46 is provided with a thumb-wheel 48 upon its outer end, whereby the tube 46 may be turned. As the thumb-wheel48 is turned the rod 45 will be moved forward or backward, as the case may be, carrying with it and moving horizontally upon the back plate 22 the feedadjuster 4l, as is best shown in Fig. 4. The feed-adjuster 41 is provided in front with a recess 49, in which the lower end of the feed-lever 37 moves.

50 indicates parallel rods secured to the feed-adjuster near the front of the recess 49, one near its top and the other near the bottom and passing across from side to side.

51 indicates a feeder which is slidingly mounted upon the rods 50, which pass through suitable openings in the feeder 51.

52 (see Fig. 4) is a roller mounted upon the back of the feeder 51 and adapted to engage with the slot 40 in the lower vend of the feed-lever 37. As the feed-lever 37 is Vibrated by the action of the cam the feeder 51 is carried horizontally backward and forward upon the rods 50. The cam 25 is driven in the usual manner in these machines, and as its construction and operation are the same as are found in machines of this character and are well known it is unnecessary to describe them more fully here.

53 indicates a feed-adjusting screw, which passes through a threaded opening in the projection 54 of the feed-adjuster 4l. By screwing the feed-adjusting screw 53 in or out the backward motion vof the lower part of the feedlever 37 will be limited by the feed-lever 37 coming against theend of the feed-adj usting screw 53, thereby regulating the distance which the feeder 51 is carried backward in tbe feed-adjuster 41.

55 indicates a gage, which is engraved or marked in any suitable manner upon the surface of the recessed portion 49 of the feedadjuster 41.

5b' indicates a point which is formed upon or secured to the lower end of the feed-lever 37 and which passes across the surface of the gage 55.

57 indicates a bar, which is secured to the end of the feed-adjuster and passes horizontally outward through a recess in the slidebox hereinafter described. The outer end of the bar 57 is provided with a number of vertical marks, which are adjusted so as to form a gage by which the movement of the-feedadjuster 41 may be regulated to the desired amount when moved-backward or forward by the action of the thumb-wheel 48, as hereinbefore described. The gage-marks upon the end of the bar 57 are so placed as to conform with the divisions upon the gage 55, so that when the feed-adjuster is moved to a position indicated by any one of the numbers upon the gage at the end of the bar 57 the point 56 upon the feed-lever 37 may be adjusted by the feed-adjusting screw 53 upon a correspending number of the gage 55, and when the machine is operated the legs or arms of the staple will be of the same length.

58 indicates a shoulder, which is preferably formed separate from and secured to the lower end of the feeder 5l, and is provided at each end with upwardly-projecting ears 59, which are pierced for the passage of the wire, so that the wire passing through them will rest upon the upper surface of the shoulder 58. I have shown the shoulder 58 as formed separately from and securedto the lower end of the feeder 51, and that is the way in which I prefer to make it; but it is obvious that it might be formed integral withI it.

6() indicates a check-pawl, which is pivoted at its upper end upon the outer surface of the feeder 5l and is provided at its lower end with a projecting pin 6l.

62 indicates a spring, which is secured at its upper end to the pivot upon which the checkpawl 6,0 turns, and at its lower end bears IOO IIO

upon the pin 6l, so as to force thelower end of the check-pawl downward toward the upper surface of the shoulder 58.

63 indicates a wire-gripper, which is piv-v otally mounted upon the lower` end of the check-pawl 60 and has its edge serrated to enable it to grip the wire. The operation of the check-pawl is such that when the feeder 51 is moved by the action of the feed-lever 37 toward the staple forming and driving mechanism hereinafter described the wiregripper coming in contact with the surface of the wire will tend to press it against the shoulder 58 and hold it firmly in position, preventing the wire from slipping upon the shoulder and forcing it forward as the feeder moves. When the feeder is moved in the opposite direction by the action of the feed-lever, the gripper will be freed by the backward motion of the feeder from the surface of the wire, permitting it to slide upon the wire.

64 indicates a shoulder similarin form and construction to the shoulder 58 and secured upon the outer end of the feed-adjuster 41,

as is best shown in Figs. 3 and 5.

65 indicates a check-pawl similar in construction and operation to the check-pawl 60 and having a wire-gripper 66 pivotally mounted on its end similar in form, construction,and operation to the wire-gripper 63, and a spring 67 operating to force the lower end of the check-pawl downward against the shoulder 64. The operation of the pawl 65 is such that when the Wire is pulled through by the forward motion of the feeder 51 the lower end of the pawl will be raised, permitting the wire to slide through. When the feeder 5l is moved backward in the opposite direction, the lower end of the pawl 65 is forced downward upon the wire, holding it against the shoulder 64 andpreventing it from moving backward as the feeder is moved backward. The wire, after passing through the feeder 51, passes through a suitable opening 68, horizontally pierced through the inner end of the feedadjuster 41.

69 indicates a wire-cutter, which is mounted so as to slide vertically in suitable grooves on the inner end of the feed-adjuster 41, as is best shown in Fig. 11. The inner end of the feed-adjuster 41 is provided with a vertical slot 70, as is best shown in'Figs. 4 and 11, and the wire-cutter 69 is pierced near its upper end with an opening 7l opposite said slot, through which opening 7l a pin secured to the staple-former, as hereinafter described, passes, reciprocating the cutter 69 with the motion of the staple-former, as hereinafter described, and operating to sever the wire as it passes out of the opening 68 close against the end of the feed-adjuster. As the wire is severed close to the end of the feed-adjuster, as aforesaid, it is obvious that the farther the feed-adjuster is moved away from the staple-forming devices by the rotating of the thumb-wheel 48 the longer the staple will be. The length of the staple is thus adjusted to Vthe tension-tube 36.

which it is desired and is mounted upon the outer end of the feed-adjuster 4l by means of a screw-lever 74 passing through the slot 73 and screwed `into the end of the feed-adjuster41, as is best shown in Fig. 4. The wire-straightener 72 is also provided with a suitable opening 75, through which the wire passes after leaving The object of the wirestraightener is to cause the wire, after passing vthrough the feed-adjuster, to enter into the staple-forming apparatus hereinafter described. If the wire after leaving the feedadjuster tends to bend downward, it may be caused to bend in the opposite direction by raising the free end of the straightener 72 a suitable distance, and if it tends to bend upward the tendency may be corrected by mov- `ing the free end of the straightener downward a suitable distance. If thewire after leaving the feed-adjuster tends to move in or out horizontally, it may be corrected by moving the straightener 72 out or. in on the thumb-nut 74 by means of the slot 73, anymovement of the wire-straightener in any direction tending to cause the free end of the wire to bend in the same direction after leaving the feed-adjuster.

76 indicates a slide-box, which is secured to the back of said plate being cut away, as is shown in Fig. 10, to permit the movement of the staple-former, hereinafter described. A

portion of one side of the slide-box, as is shown in Fig. 10, is cut away to permit the movement of the knife-pin upon the stapleformer, hereinafter described.

79 indicates a guide, which I prefer to form separately from and secure to the lower end of the slide-box 76, as is shown in Figs. 10 and l2, for the purpose of forminga guide at the lower end of the groove 78. formed integral with the slide-box. The lower end of the slide-box 76 is pierced with an opening 80 for the passage through it of the lower staple-former, hereinafter described.

Y 81 indicates an upper staple-former, which is mounted and adapted to reciprocate in the groove 78 of the slide-box 76. The upper staple-former 81 is provided at its upper end with a roller 82, which is rotatably mounted thereon and adapted to rest in and be operated by the cam-groove 27 in the cam 25, causing the staple-former to reciprocate up and down as the cam 25 is rotated. As this operation of the cam and the reciprocating of the staple-former are old and we ll known in this class of machines it is not necessary to de IOS lt may, of course, be

IZO

scribe them more fully in detail. The upper staple-former 81 is, in general, of the same form and method of operation as the older and well-known form of upper staple-formers in machines of this class, and is provided with a vertical groove at its front, in which a driver 83 reciprocates, as hereinafter described. The upper staple-former 81 is provided near its upper end with two recesses 84, one upon each side, and with a horizontally-projecting pin 86, (see Fig. 5,) adapted to engage with the opening 71 of the cutter 69 and reciprocate the cutter as the upper staple-former is reciprocated by the action of the cam. The pin 86 projects into and works in the cut-away portion at the side of the slide-box nearest the feed-adjuster, as shown in Fig. 10.

87 indicates a staple-supporter, which is, in general, of the form and construction well known in this class of machines, except that at its upper end it is provided with afork 88, which rests in the recesses 84 in the upper staple-former 81, and is provided with a pin 89, projecting horizontally forward at its upper portion, as is'best shown in Figs. 6 and 7.

90 indicates a face-plate, which is removably secured to the outer surface of the slidebox 76, as is shown in Fig. 3 and indicated by dotted linesin Fig. 6. A central vertical opening is cut in the face-plate 90, and a spring 91 is mounted upon the face-plate 90 and passing into said opening bears against the lower end of the supporter 87, forcing it inv ward, as is best shown in Fig. 8.

114 indicates a spring, which is secured at its upper end upon a pin 115, projecting downwardly from the pin 89 at its lower end in an opening 116 in the top of the face-plate 90. The spring operates to move the staple-supporter 87 upward when freed from the upper shoulders formed by the recesses 84 as the upper staple-former moves upward, as is best shown in Figs. 6 and 8.

83 indicates a driver, which is mounted in the groove in the front of the upper stapleformer 81, so as to slide freely vertically therein.

92 indicates a link, one end of which is pivoted eccentrically on the cam 25 and the other end pivotally secured to the upper end of the driver 83, as is best shown in Figs. 3 and 5, causing the driver 83 to reciprocate vertically as the cam 25 is rotated. The driver 83, as is best shown in Fig. 8, and the upper stapleformer 8l, as is best shown in Fig. 6, are each provided with a small groove across the bottom, in which the wire rests when the devices are in operation. The lower portion of the back of the upper staple-former 8l is cut away at the lower end of the recess therein, as is best shown in Fig. 8, enabling the sides of the staple-former to straddle the lower stapleformer, hereinafter described, and the supporter 87 as the machine is operated.

93 indicates a box, which is secured to the back plate 22 and projects horizontally backward therefrom.

' 94 indicates a lower staple-former, which passes through the opening 80 in the slidebox 76 and into the box 93.

95 indicates a spiral spring surrounding the lower staple-former 94 in the box 93 and bearing against a shoulder 96 of the said lower staple-former 94 and against the end of the box 93 and operating to push the lower stapleformer forward under the upper stapleformer and hammer, asis best shown in Fig. 8. The front end of the lower staple-former 94 is rectangular in cross-section, as is best shown in Fig. 5, and is beveled above and below, as is best shown in-Fig. 8. It is also provided with a slot 97, extending-transversely across its end, as is best shown in Figs.v 5 and 8, of suitable size for the wire to pass through it.

98 indicates a saddle-frame, which is mounted upon the upper end of a block 99, which is hollow, in order to permit the passage through it of parts hereinafter described.

100 (see Fig. 9) indicates a nut, which is secured to the end of the goose-neck 18.

101 indicates a bolt, which is provided with a shoulder 102, that bears against the lower portion of the block 99, as is best shown in Fig. 9. The bolt 101 passes through the nut 100 and is provided at its lower end with a hand-wheel103, which operates as it is turned to raise or lower the block 99, carrying with it the saddle-frame 98. The bolt 101 is pierced to permit the passage through it of parts hereinafter described. A

104 indicates a table, which is divided longitudinally in two parts, which are hinged together, as is best shown in Figs. 1 and 3.

105 indicatesbraces, which are hinged below the table 104. The braces 105 are adapted to rest in grooves 106 at the bottom of the saddle-frame 98 and operate when in position to hold up the two parts of the table 104, so that it may form one continuous level surface. When either of the braces 105 is free from the grooves 106 in the saddle-frame 98, the corresponding part of the table will drop down, so as to rest upon the saddle-frame 98. Either side or both sides of the table 104 may be so dropped as may be desirable from the nature of the work that it is desired to stitch.

107 indicates a clincher-block, which is secured upon the upper end of the block 99, as is best shown in 'Figs 9 and 13.

108 indicates ciinchers, which are pivoted in said clincher-block 107 in an opening extending through said clincher-block, as is best shown in Figs. 13 and 14. The clinchers 108 `are of a U shape, and are pivoted near the bottom of one arm of the U, as is best shown in Fig. 13.

109 indicates a clincher-rod, which passes through the block 99 and downward through the hollow bolt 101. The lower end is pivotally connected with a lever 110,which projects outward from the lower goose-neck 18. The inner end of the lever extends within the supporting-pillar 17 of the machine, and is moved up and down by any well-known cam or other IOO reciprocating mechanism located within the pillar and connected with the driving-pulley 21 and operating, as the said lever 110 is vibrated, to reciprocate the clincherrod 109 vertically. The lever 110 and the devices by which it is operated are of the ordinary and well-known form and construction in this class of machines, and it is therefore not necessary to describe them. The upper end of the clincher-rod 109 is provided with two lugs 111, which are elongated and adapted to loosely rest between the two arms of the clinchers 108 and operate to throw the upper arms of the clinchers up when the clincherr0d 109 is moved vertically upward and to bear against the lower Varm and throw the clinchers down when the clincher-rod 109 is moved downward. The lugs 111 are elongated for the purpose of affordinga continuous support and a firm bearing for the clinching-arms Y of the clinchers 108 when they are forced upward to clinch the staples, as is best shown'in Fig. 13.

112 (see Fig. 9) indicates a jaw, which is secured upon the outer end of the goose-neck 18. 113 indicates a jaw, which is secured upon the lower end of the block 99 immediately below the jaw 112 and moving with the block 99. The jaws'1l2 and 113 are so adj usted that the distance between them may be the same as the distance betweenthe top of the table and the operative parts of the staple forming and driving mechanism, thus forming a gage by which the height of the table may be adjusted to the thickness `of the work which it is required to fasten. The work is placed between the jaws 112 and 113, and by turning the hand-wheel103 the block 99 is moved until the distance between the jaws 112 and 113 corresponds to the thickness of the work. The work is then removed and the staple will be adjusted at a suitable distance from the staple forming and driving mechanism.

. 117 indicates atable, which is mounted upon `through the tension-tube .36, through the straightener 72, and through the openings in the shoulder 64 below the check-pawl 65. It is then passed through the openings in the ears 59 of the shoulder 58 below the checkpawl 60 and threaded through the opening 68 in the end of the feed-adjuster 41. Asthe machine is set in motion, the cam 25 revolving, bringing the cam-surface 26 in contact with the roller 39 upon the feed-lever 37, throws it outward, the inner end of the feed-lever.37 being carried inward, carrying with it the feeder 51, thus carrying the wire forward into the slot 97 of the lower staple-former 94,

the feed-adjuster 41 having been previously adjusted according to the length of the staple which it is desired to use. The portion of the outer cam-surface 26 between the stars on Figs. 3 and 5 is an arc of a circle whose center is the center of the driving-shaft 20. The upper end of the feed-lever having been thrown over to its greatest extent, the roller 39 bears upon the portion of the cam which is the arc of a circle, and the feed-lever is therefore retained in the position in which it has been thrown by the operation of the cam until it passes beyond the end of that p0rtion which is the arc of a circle. As soon as the feed-lever 37 has been operated to throw the wire into the groove of the lower stapleformer the cam-groove 27 begins to operate upon the roller 82 of the upper staple-former 81, moving itdownward with the driver.4 As the staple-former begins to move downward, the pin 86 engaging with the opening 71 of the cutter 69 brings the cutter 69 downward upon the wire and severs it as the downward motio'n of the upper staple-former is continued. Its lower end straddling the lower staple-former 94 engages the wire in the groove at the bottom of the upper staple-former and bends the free ends of the wire downward over the lower staple-former 94 into the form of a staple around the lower end of the supporter 87, which is carried downward as the upper stapleformer moves downward by the action of the upper shoulders of the recesses 84 coming in contact with the fork 88. The portion of the groove between letters a and b in Figs. 3 and 5 is an arc of a circle of which the center is the axis of the driving-shaft 20. As the cam rotates so that the roller 82 passes beyond the point a the upper stapleformer is held in the same position while the roller is passing upon the portion a b of the cam-groove 27. As the roller 82 comes to the point a, of the cam-groove 27 the link 92, as the cam 25 rotates, forces the driver 83 still farther downward. As the driver comes against the beveled surface of the lower staple-former 94 it forces it inward, leaving the staple which has been formed by the action of the upper staple-former in its place between the sides of the upper stapleformer 81 and the supporter 87 until the staple is freed from the lower staple-former, the upper staple former and supporter having been carried downward to their lowermost limit and resting upon the surface of the work. As the driver continues its downward course, the top of the staple engages with the groove in the bottom of the driver, and the driver coming in contact with the beveled top of the hinged portion of the supporter 87 forces it outward as the driver descends, thus supporting the sides of the staple as it is driven through the paper until the supporter 87 is forced backward till the staple passes o from its point and the staple is driven homeby the action of the driver. As the staple is driven through the work, the points come in contact IOC IIO

' spring hereinbefore mentioned to its former position at the proper time to permit it to again grip the wire and push it under the staple-former, as before. The bearing-surfaces of the cam-groove 27 and the link 92 are so arranged as to return the upper staple former and driver to their original positions after the staple is driven. As the clincher-rod 109 is moved downward after the staple is clinched, the lugs 111 coming in contact with the lower arms of the U-shaped clinchers 108 return the clinchers to the original position shown in Fig. 13. In case the wire passing through the machine bends so as not to enter the groove in the lower staple-former the wire-straightener 72 is adjusted to cure the difficulty, as above described.

Before the machine is set in motion the parts are adjusted by means of the thumbwheel 48 and the feed-adjusting screw 53 until the point 56 indicates the same position upon the gage as is indicated by the gage upon the arm 57, thus causing the two legs of the staple to be of the same length.

That which I claim as my invention, and desire to secure by Letters Patent, is-
