SPECIFICATION forming part of Letters Patent No. 429,540, dated June 3, 1890.
Application filed April 2, 1889. Serial No. 305,682. (No model.)
To all whom it may concern:
Be it known that 1, WILLIAM O. MILLER, of Quincy, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Stapling-Machines forForming Leather Loops, &c.; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked thereon.
This invention relates to an improved machine for inserting staples in leather and similar material and for forming loops or rings of such material, the abutting edges of the material being united by staples, the object of the invention being to produce a machine for performing the operations mentioned automatically and with great rapidity, and at the same time a machine of great simplicity, which can be produced and operated at comparatively little cost.
To these ends the invention consists in a staple holding and driving mechanism for in-, serting two staples parallel to each other, togeth'er with staple-receptacles for feeding the staples forward at the proper moment.
The invention further consists in combinin g with a stapling mechanism, preferably such as described, an anvil and jaws for grasping and holding a leather loop, and, if desired, bending the same into shape for the insertion of the staples, with mechanism for automatically performing said operations and feeding the leather blank and discharging the completed loops at the proper times. And the invention further consists in certain novel details of construction and combinations and arrangements of parts to be hereinafter described, and pointed out particularly in the claims at the end of this specification.
In the accompanying drawings, Figure 1 is a perspective View of a machine constructed Fig. 2 is a side elevation showing a modification. Fig. 3 is a sectional view through the staple holding and driving devices. Fig. 4 is a sectional viewthrough the anvil and loop bending and holding devices. Fig. 5 is a view of a modified forni of folding-arms. Fig. 6 is another modification of the same.
Similar letters and numerals of reference in the several figures indicate the same parts.
same time the maximum strength. Working in suitable bearings in the upper end of the standard 1 is the plunger 3, held in elevated 'position bythe spring 4 taking its bearing on the standard and beneath the enlarged upper end of the plunger, on which the cam or lever 5 for forcing the plunger down rests, the bearing for said cam or lever being also in the top of the standard, preferably in eX- tensions 6, Fig. 1.
Mounted on the lower end of the plunger 3 is the block or head 7, capable of a sliding movement up and down, the spring ct serving to keep it normally depressed, in which position the side passages 11, through which the staples enter, are open, as the ends of the arms of the plunger are above them. Said side passages communicate with the central passages c, from which the staples are ejected into the leather by the arms of the plunger, as will be readily understood, suitable retaining-sprin gs being arranged therein, of course, to prevent the staples from dropping out before the plunger descends.
The staples may be fed into the side passages by hand; but in the preferred construction I provide hoppers 8 8, which may be mounted on the head 7, but preferably, as shown, only register therewith when the plunger and head are elevated, suitable staple retainin g and feeding devicessuch as the levers d with the two projections d d extending into the path of the staples and operated in one direction by the springs e to throw the lower projection in to engage the bottom staple and operated by the cam surface or projectionf on the head to release the bottom staple and cause the upper projection to engage the neXt staple above, being provided for feeding one staple at a time and cutting off the feed when the plunger and head are depressed.
An operating wheel or disk 9 is mounted on the base at the rear of the standard 1, to which the power is applied for driving the Various parts of the machine through intermediate levers and appropriate gearing, to be hereinafter described.
The preferred mode ofoperating the lever or cam for depressing the plunger is by apin g on wheel 9, working in a slot 9' in the long arm of the lever, as shown in Fig. 1; but, if desired, the plan adopted in Fig. 2, in which a link g connects the lever and wheel, may be employed to advantage.
When the machine is particularly designed. for forming loops of leather and similar material for harness, 860., the anvil portion of the standard 1 is provided with means for folding the ends of the strip laid thereon and for holding such strip in position with the ends abutting or in juxtaposition until the staples are inserted. In Fig. l a die 10 is placed on the anvil portion of the standard having the raised portions h h on each side,and lying in proximity to the die on each side are the folding-arms 11 7;, supported 011 the standard and operating when the strip has been pressed into the die to fold the ends over flat, as shown in Fig. 4, and retain them in this position until the head and plunger descend and insert the staples, suitable slots or openings I I being formed in the folding-blades for the passage of the staples.
The folders are operated periodicallyby the wheel 9, a wedge-shaped cam being formed on its periphery, which as the wheel rotates enters between the inwardly-turned ends 7? t" of the arms 1? and rotates the same, turning the blades in over the die. Before the cam 7i; has passed the plunger descends and inserts the staples.
Instead of rotating the folding-arms as just described, it is obvious that they may be, as shown in Fig. 5, pivoted together or to the frame at approximately their centers, and have a movement toward and from each other without any rotary movement; but the devices first mentioned are found to give better results, and are therefore preferably employed.
It is essential that some device be employed around which the loop can be formed, and which will serve to clinch the ends of the staples, such as a clamping-rod or bar 12, having its rear end connected loosely to the rod or extension 14, provided with the hook 15, engaging the projection 16 on the wheel to reciprocate the said bar and the strip-feed ing mechanisms, which latter will be presently described. This bar 12, besides being moved longitudinally, is capable of an oscillatory movement up and down, such movement being caused by the lever m, pivoted in the standard and having the extended arm m encircling the bar a short distance back of the die, a spring m engaging said lever, serving to keep the bar normally elevated, and a spring m serving to keep it normally pressed forward over the die. The cam is,
engaging the lever in, depresses the bar or clamp and forces the strip lying across the die down into the same in position to have the ends folded in, and after the stapling operation the projection 16, engaging the end of the extension or rod, as aforesaid, draws the bar or clamp out, and the loop, coming in contact with the encircling arm m, is pushed off the said bar or clamp.
A mechanism for feeding the blanks is provided, consisting of the carrying-arms 0, moving in guides 0' on the side of the standard and connected at their rear ends to the rod 14, which gives the carrying-arms the necessary reciprocating movement. The forward ends of the carrying-arms are provided with teeth or projectionsp, which engage the blank or strip and draw it forward to a position over the die in position to be folded, as before described.
If desired, a hopper may be provided for the strips, as shown in Fig. 2, and the teeth or proj ections p be arranged to engage only the bottom one and draw it forward, as will be understood upon an inspection of said Fig. 2.
The mechanism for operating the various parts may be changed and altered in various ways without departing from the spirit of my invention-as shown, for instance, in Fig. 2, wherein it will be particularly noted that besides the difference in the plunger-depressing mechanism before pointed out the bar and feed operating devices are separate and som e what altered, the bar being in this case mounted to slide freely in a bearing 0", pivoting in the standard, the projection on the Wheel for withdrawing it, however, being the same, and is so arranged in both instances that when the wheel has rotated to the proper point the curved surface s will throw the hook out of engagement and allow the bar to return to normal position. The rod t for operating the feeding devices in Fig. 2 is operated by the projection 15 on the periphery of the wheel out of the line of the lever.
In the modification Fig. 6 the sides of the die are dispensed with and the folding arms are bent at substantially right angles at the points 4), and are adapted, after the bar has clamped the strip in place, to fold the same clear over the top, as shown.
From the above description the operation of the machine will be readily understood; but for the sake of clearness I will set forth, briefly, the sequence of operations performed by the machine in making a harness-loop.
Assuming that the parts arein the position shown in Fig. 2, the first movement is of the feeding-arms, which carry the blank forward to a position over the die and then being released from the projection 15 immediately retreat; the cam on the wheel then comes in contact with the lever and moves the bar down, clamping the blank and forcing it into the die; the folding-arms being then operated on by the cam fold the ends of the blank over the bar and hold them in such position plunger reciprocating therein, the head.
'the staple ahead and into the leather, the
head forming the staple support and guides. As the plunger rises the spring moves the headagain to normal position.
It is obvious that the equivalent of the elements, going to make up the complete machine herein described may be employed without departing from the spirit of my invention, and therefore I do not wish to be understood as limiting myself to the particular devices Set forth. 7
