STAPLING-MACHINE.
SPECIFICATION forming part 'of Lettere Patent No. 761,365, dated Mey 31, 1904.
Appneetienrliec. Meret 27, 1903.
in Stapling-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification. l
My invention relates to certain improvements in that class of machines used in forming and driving staples' into veneer boxes or baskets or like articles; and the invention consists in features of lnovelty hereinafterfull y described, and pointed out in the claims. l Figure I is a front elevationof the'machine with the face-plate of the staple forming and driving `bar housing removed. Fig. II is a longitudinal section ofthe machine, taken on -line II II,Fig. I. Fig. III is a transverse sec- VIII, showing the staple forming and driving bars in the position assumed when the .staple hasvbeen driven. Fig. X is a section taken through the staple-forming members in the position assumed previous to the act of drivingy the staple after it has been formed. Fig. XI

the staple. Fig. XII is a vertical section taken on line XII XII, Fig. XI. Fig. XIII is a vertical section of the upper portion of they die-box. Fig. XIV is a section of two layers of material with a staple formed upon my machine illustratedas driven therethrough. Fig.
Serial No. 149,789. (No model` XV is a view of the under side of the layers of l material shown in Fig. XIV. Fig. XVI is a cross-section on the line XVI XVI, Fig. II.
1 designates thepost of my machine, which is surmounted `by a table 2. e
3 is a frame-upright surmounting the rear end of the table 2 and supporting a hollow forwardly-projecting frame-arm 6.
7' is a housing bearing a face-plate 8 and secured to the forward projecting frame-arm 6 by a neck 9, fitted into said arm.
10 is a bushing seated in the rear end of the frame-arm 6.
11 designates a longitudinal drive-shaft extending through the frame-arm 6 and jou rnaied in the housing-neck 9 and bushing 10.
12 designates a die-box set in the forward end 'of the table 2 beneath the housing 7. In
the box 12 is avertically-reciprocating die 13, provided with an arm 111 and normally held depressed by a spring 15. (See Fig. II.) The die 13 is operated by mechanism hereinafter described. The die-box 12is mounted in the table 2 for vertical adjustment therein by an adj ustment-screw12, that bears against an arm 12b, carried by the box. Through the medium of the adjustment-screw the box is raised or lowered and `I thereby 'vary the elevation'of the box for the purpose to be hereinafter mentioned. At the lower end ofthe housing 7 is a guide 16through which the staple-wire is delivered to the forming and driving mechanism, as will hereinafter appear.
17 is a bracket extending laterally from the lower end of the housing 7, and4 in which is journaled va shaft 18, that carries a feed-wheel 19. The staple-wire passes between this feedwheel and a roller 2O beneath it from a guide 'l 21, as-illustrated in Fig. I. The sha-ft 18 extends krearwardly from the bracket 17 and bears at its rear end a ratchet-wheel 22.
The ratchet-wheel 22 receives the engagement of a springpressed pawl 23, carrled by a slotted reciprocating bar 24, thatis driven by an'eccentric 25, mounted on the drive-shaft 11. I
fork 27 of a lever 28,vibratorily supported by a rock shaft 29, journaled in the wall of the frame-upright 3. p
30 isa reciprocating bar pivoted to the lower end of the lever 28 and extending forwardly through an aperture in the frameupright 3 and leading to the housing 7.
31 is a linger slide that is detachably cio-nnected to the reciprocating bar 30 by a tongue 32, projecting from said bar and fitting in a:
socket in said finger-slide. The slide 31 carries a form-finger 33, which projects forwardly therefrom. The finger-slide 31 is `supported by a bracket guide 34, depending from the housing 7. This slide is detachably connected to the bar 30, by which it is carried,for the purpose of permitting its ready disconnection therefrom and removal for repair or introduction ofl a new slide to take its place when it becomes worn in the service, to be hereinafter referred to. The finger 33 ofthe slide 31 is adapted to be projected forwardly bey neath a vertical box-bracket 34 at the lower grooves 42.
In the practical operation of forming andl 4o the plunger-finger 38 and the inner facingy sides of which contain at theirlower ends (See Figs. 1X, XI, andXIl.)
driving the staples the described mechanism is actuated through the medium of the driveshaft 11. On the .rotation of said shaft the staplewire-A (see Figs. I, VIII, and X) is fed through the guide 16 by the actuation of the feed-wheel 19, which is operated by the eccentric and ratchet mechanism connecting it to the shaft. YThe staple-wire is thereby fed horizontally across the space 34 beneath -the housing 7. At the same time that the staplewire is fed forwardly through. the guide the form-finger 33 is projected into a position beneath the space 34 by the reciprocation of the bar 30, actuated by the lever 28, having en:
gagement with theshaft-carried cam 26. Ro.- tation of the drive-shaft causes the wrist-pin 3,5 to be carried upwardly and then downwardly inthe cam-slots of the forming and driver bars. 36 and 39. As said wrist-pin begins to move downwardly in its travel it first acts upon the cam-face at the bottom of the S-shaped slot 40 of the forming-bar and forces said bar downwardly without moving the driver-bar. Theforming-.fngers 41 are thereby carried to the wire projecting across the space 34, and the linger near the inner end of the guide 16 severs said wire, so that a short section from which the staple is to be formed will lie across the form-finger 33 beneath the space 34. The forming-,lingers 41 continue their downward movement and bend the ends of the section of staple-wire downwardly over the form-finger, thereby producing the staple, the legs of which seat in the longitudinal grooves 42 in said fingers, as seen in Figs. X1 and XII. The wrist-pin 35 next begins to act on the cam-face at the lower side of the crescent-shaped cam-slot 37 in the' driver-bar in the position seen in Fig. VIH, and as the wrist-pin moves upwardly against said face the driver-bar is carried downwardly to convey the plunger-fin ger 38 tothe staple situated between the forming-lingers 41. During the initial rperiod of travel of the driver-bar the form-finger 33 recedes from its projected position bythe reciprocation of the bar 30. Then on the continued downward movement of the plunger-linger 38 the staple is moved downwardly between the forming-lingers until it reaches the material B, (seen in Fig. XI into which it is driven. As the staple is driven through the material its legs strike the die 13, and their points are bent on contacting with the die and forced into clenched contact with the material, as seen in Figs. XIV and XV. Y
By making the dic-box 12 vertically adjustable Iam enabled to position the die 13 at any desired distance from the forming and driving iingers of the machine, and thereby provide for the driving of staples of varying lengths withoutdanger of their being bent or buckled in forcing them through the box or basket that receives them. Moreover, the thickness of boxes or baskets vary, and it is necessary to provide the requisite space in which all degrees of thickness may be used, which I do by the adjustable mounting of the die-box.
43 designates a treadle pivoted at 44 to the post 1 of' the machine, and through which the IOC IIO
is pivoted a connecting-rod 46, that leads upwardly to a clutch-retainingyoke 47, which is normally held in a lowered position by a spring 48. (See Fig. 1I.) The yoke is slidably fittedvto a stud 4,-projecting from thc frame-upright 3, and it contains a slot 49, that receives the drive-shaft 11, with respect to which the yoke is capable of vertical movement. For the purpose of preventing the I yoke from riding on the drive-shaft to occasion wear of the parts a boss 50, which moves in a groove 6 in the rear face of' the framearm 6 and when at rest at the bottom of' said groove supports the retaining-yoke off of the drive-shaft 11. (See Figs. 1V and V.)
51 is a stop-block attached to the retainingyoke 47 'and provided with an inclined face 52, as'shown in Fig. VII.
53 is a `hardened plate secured to the retaining-yoke alongside of the drive-shaft 11. 54 is a loose pulley mounted on the outer n end of the drive-shaft 11, and` 55 represents dogs carried by said pulley.
56 is a clutch keyed to 'the drive-shaft 1 1 between the retainer- 47 and the loose pulley 54. In this clutch is a bolt 57, that is provided' with a projecting arm 5 8 and is backed` to project the bolt 57 toward the loose pulley 54. One of the dogs55 then engages said bolt and causes rotation of the clutch, and
consequently of thedrive-shaft to actuate the staple forming and driving mechanism of the machine. When it is desired to stop the operation of the machine, pressure upon the treadle is relieved, and the spring 48 carries the retaining-yoke 47 downwardly, with the lresult that the bolt-arm 58 passes into a position back of the stop 51 and effects stoppage lof the clutch and drive-shaft until the retaining-yokeis again elevated. v
For the purpose of preventing sudden jar and wrenching of the mechanism of the machine in stopping the drive-shaft and its clutch I provide a cushion-pin 60, located in a barrel 61, carried by the retaining-yoke 47 (see Figs. IV, V, and VI) and backed by a spring 62. Thiscushion-pin receives the clutch-bolt arm 58 when it passes back of the stop 51 into the position seen most lclearly in Fig. VI. To prevent recoil of the `'clutch 56 on striking the cushion-pin 60, I provide a spring-pressed stop-pin 63, set into the clutch and projecting from its inner face toward the retaining-yoke 47. This recoil-pin passes across the hardened stop-plate53 when the clutch is brought to rest and projects into a recess in the re taining-yoke, as vseen in Fig. VI, where it acts to stop retrograde rotation of the clutch when the bolt-arm 58 has struck against thev cushion-piny 60 in its stoppage.
Each time that the'staple forming and driving mechanism of the machine is operatedto produce a staple and present it to the die 13 said die is carried vertically toward the approaching forming and driving fingers 38 and 41 by mechanism that will now be described.
64 designates a rotatable shaft extending longitudinally of the machine and having its rear end supported in a swinging journal-box pivotally mounted in a bracket-arm 65. The
.70 striking the arm of the die.
rear end of the shaft 64 bears a crank 66, that is connected by a pitman 67 to a crank 68, carried by the drive-shaft 11, through the mediumof which the rotatable shaft 64 is driven. Fixed to the forward end of the shaft 64', which passes through and has vertical play in a slot in a web depending from the table 2, isa crank 69, that has bearing in the die-box 12 and bears a pin 70, adapted to engage the arm 14 of the reciprocating die 13 in each rotation of the shaft 64. During the rotation of the main drive-shaft 11 reciprocation is constantly imparted to the pitman 67, and the crank 66 is rotated to impart like movement to theshaft 64 and crank 69. Whenever the die-box 12 is shifted vertically, it will be seen' that the forward end of the shaft 64 may rise or fall therewith by moving in the slot in the web depending from the table, this rise-and-fall motion being permitted in consequence of the swinging mounting of the gear end of the shaft 64 in the bracket 65. As the staple forming and driving fingers move downwardly toward the die 13 in each operation, the shaft 64, by its connection with the drive-shaft, is rotated, and the die isreciprocated by the crank-pin The fingers and die are therefore carried toward each other, and pressure against the staple is eX- erted both from above and below to quickly and efliciently clench the staple when driven through the thicknesses of material it secures. The spring 15 returns said die to lowered position after each upward movement thereof.
