MACHINE FOR MAKING STAPLES.
SPECIFICATION forming part of Letters Patent No. 498,040, dated May 23, 1893.
Application filed November 2'7, 1888. Serial No. 291,992. (No model.)
To all whom it may concern.-
Be it known that I, WENDELL P. WHITE, a citizen of the United States, residing at B rockton, in the county of Plymouth and State of Massachusetts, have invented a certain new and usefullmprovement in Machines for Making Staples, of which the following is a specification.
The object I have in viewis the production of a machine for making staples of insulating material, such as are described in Letters Patout No. 317,879, and which have heretofore been made by hand. These staples are made from strips of any suitable insulating material, vulcanized fiber or wood being a good material for the purpose. The strips have a width equal to the entire length of the staple and the staples are first cut transversely from the strip and are then bent in the center to give them the staple form. Before bending,
the strip of vulcanized fiber or wood must be softened and the staples must be held in shape while the material is hardening. I have found it desirable to soften the strip with alum water, or with steam, before it is presented to the machine.
My machine is designed to form the staple complete from the strip, it first cutting the staples from the strip, then bending them, and then delivering them to a suitable mandrel or holder attached to the machine,which has a capacity for a great number of staples and which is adapted to be removed from the machine and to be placed in a suitable oven for the drying and hardening of the staples.
My machine is provided with various adj ustments for enabling staples of different lengths and widths and having different distances between the legs or sides of the staple to be made upon the same machine, and it also has various features of construction to meet the requirements of work of this character, as will be hereinafter pointed out in detail.
My invention consists in various novel devices and combinations of parts, all as more fully hereinafter explained and pointed out by the claims.
In the accompanying drawings forming a part hereof, Figure 1 is a top View of the machine. Fig. 2 is a side View; Fig. 3 a sectional view of a part of the mandrel or carrier and showing some of the adjacent parts. Fig. 4 is a vertical section through the table of the machine and the mandrel showing adjoining parts in elevation. Fig. 5, is an end view of the mandrel carrying shaft showing the pivoted bearing block; Fig. 6, an elevation of the gate through which the strip is fed; and Figs. 7, and 8, are respectively end and top views of the strip.
A is the frame of the machine from which rise standards A, in which is journaled the driving shaft 13. On the center of this shaft between the standards are two small cams or eccentrics a a, and between these two is a third cam or eccentric b, the eccentric I) having a greater throw than the eccentrics a, C1,, but acting at the same point in the revolution of the shaft.
0 is a bifurcated rocking arm mounted upon a shaft 0' at the rear of the frame and projecting forward under the shaft B, where it is provided with a head 0 carrying a cutting knife D and a guide arm D. Working between the two sides of the bifurcated rocking arm 0 is a rocking arm E,which is mounted at the rear of the frame upon the shaft E and likewise projects forward under the driving shaft B, where it carries a bending knife E working in the rear of the cutting knife D. The two eccentrics a a bear upon the rocking arm 0, while the central eccentricbbears upon the rocking arm E. These rocking arms are thrown upwardly by springs c and are depressed by the eccentrics a, a b, the efiect of the movement being to first depress both rocking arms together until the highest point of the eccentrics a a is reached, when a continuation of the movementdepresses alone the bending rocking arm E to a further extent. The cutting knife D and the bending knife E are held by suitable set screws for permitting proper adjustment in all directions to set these knives to the exact adjustment required.
F is a supporting block mounted upon the frame in front of the cutting and bending knife. This block carries a horizontal cutting knife F, held and adjusted by proper screws, which horizontal cutting knife F presents a cutting edge at right angles to that The guide arm D which is attached to the head 0 of the rocking arm 0 is also adjustably held by screws, so that its vertical as Well as its lateral position can be varied.
This guide arm projects down in the rear of andbelow the cutting knife D and its point e is turned forward and forms a gage to determine the width of the staple which will be out from the strip. Attached adjusta'bly to the block F on its edge next to the cutting knife D are two plates ff, carrying studs g, having preferably antifriction rolls upon 1 them. These studs are adjusted toward each 1 other beneath the cutting edge of the horizontal knife F and centrally beneath the vertical cutting knife D. The bending knife E passes between these studs g, and by doing so bends the staple which has been cut from the strip. By adjusting the plates ff toward and away from each other the staples will be given a greater or less distance be- These studs 9 are located at a point beneath the lower limit of tween their sides or legs.
movement of the vertical cutting knife D.
G is a shaft extending transversely beneath the cutting andbending knives. shaft is journaled at one end in a bearing h, having a friction strap h" adjusted to place more or less friction upon the shaft and to prevent anyretrograde movement. The other end of the shaft G is journaled in a pivoted bearing '6', which is adapted to be thrown down when desired, for slipping the mandrel or staple carrier on to or off of the shaft.
a purpose which will be presently explained.
Upon the shaft G is removably mounted the mandrel or staple carrier H. This isa sleeve provided with a spiral groove 70, which is the j shape and size of the head of the staple. The machine will be provided with different man- I drels having grooves of different width, so that when the other parts of the machine are adjusted for a particular size of staple, a
proper mandrel having a groove correspond- I is a guide arm, havinga finger which takes in the groove is of the mandrel, so that as This f The shaft G at this end is also made hollow for a 1 short distance, as shown in Figs. 1 and 5, for
shaft G is turned the mandrel will be advanced by the engagement of the finger of this guide arm I with the spiral groove of the mandrel. The guide arm I is pivoted upon a block I, which is secured to the frame and is adjustable by screws laterally and longitudinally, so as to adjust it to the different mandrels that may be placed upon the machine.
A rod m projects from the under side of the 1 arm I and this rod is connected with a sliding bar 11. which projects forward beneath the frame, so that by the moving of the sliding bar n the guide arm can be thrown up into engagement with the mandrel, or dropped away from it, the former position being maintained by a shoulder n on the sliding bar it. It is necessary to drop the guide arm I out of engagement with the mandrel H when it is desired to remove the mandrel from the machine.
To give the shaft G an intermittent feeding movement it is provided with a ratchet wheel 0 which engages a spring pawl 19 attached to an arm L rocking on the shaft. This arm is oscillated byapitman M from the end of the shaft B to which it is connected eccentrically. This pitman is connected with the arm L'by means of a slot 13' and a set screw or bolt 19 so that thethrow of the arm L can be varied and the pawl can be made to engage every tooth of the ratchet, or to skip one or more teeth at each movement so as to turn the shaft and the mandrel to a greater or less extent for each movement, as maybe required, to accommodate the staple.
N is a 'lever'pivoted upon the base and ghaving at one end a tooth which normally rests just above the strip that isbei-ng fed over the horizontal cutting knife F. The other end of this lever is forked, one of its fingers being struck by a stud g on the end of the mandrel, while its other finger at the same time lifts the pawl 10 out of engagement with the ratchet 0, so that the farther feed movement of the mandrel will be stopped.
The lever N has 110 function in the operation of t'he-machine-until the mandrel reaches the end of its movement, when it is desirable that it should not be fed any fart-herand that no more staples should be cut from the strip,
although the machine may continue to run material P from which the staples are cut is fed over the horizontal knife F and through the opening of the gate (1, by means of a weight or spring which keeps it forward, as will be well understood. Thexforward end of the strip P strikes the gage e; the downward 'm pvement of the cutting knife D cuts off the thrust into the groove of the mandrel, suchgroove holding them in their proper shape until the mandrel is entirely filled, when it is removed from the machine and placed in an oven to dry and harden the staples. To give the staples a proper point the edge of the strip P is shaved in one or in both directions, or is notched, as shown in Figs. 7 and 8.
In removing the mandrel from the shaft G a wooden arbor carried by the hand is slipped into the hollow end of the shaft G and the mandrel is slipped oli' of the shaft G onto this hand arbor by which it is held in the oven. A new mandrel is placed on the shaft G and the operation is repeated. By reason of the great length of the spiral groove of the mandrel, each mandrel is adapted to carrya large number of staples.
What I claim is- 1. In a machine for making staples of vulcanized fiber, wood and similar materials, a turning mandrel or holder having a spiral groove for the reception of the staples and a feed movement for advancing the mandrel so as to present unoccupied portions of the groove for receiving the staples, substantially as set forth.
2. In a machine for making staples of vulcanized fiber, wood and similar materials, a turning mandrel or holder mounted removably upon the machine, havinga spiral groove for the reception of the staples and a feed movement for advancing the mandrel so as to present unoccupied portions of the groove for receiving the staples, substantially as set forth.
3. In a machine for making staples of vulcanized fiber, wood and similar materials, the combination of vertical and horizontal shearin g knives for cutting the staples transversely from a strip, with a bending knife for bending the staples and adjustable studs between which the bending knife acts, substantially as set forth.
4. In a machine for making staples of vulcanized fiber, wood and similar materials, the combination with the cutting and bending knives, of the turning mandrel having a spiral groove, the shaft upon which the mandrel is removably carried and the dropping or removable guide arm for advancing the mandrel as the shaft is turned, substantially as set forth.
5. In a machine for making staples of vulcanized fiber, wood and similar materials, the combination with the cutting and bending knives, of the turning mandrel having a spiral groove and an adjustable feed movement for such mandrel whereby it will accommodate staples of different Widths, substantially as set forth.
(3. In a machine for making staples of vulcanized fiber, wood and similar materials, the combination with the cutting and bending knives, of the turning mandrel, a feed movement for such mandrel, and a stop lever operatedby a stud on the mandrel and acting to stop the feed movement and to hold the strip of material when the mandrel is filled, substantially as set forth.
This specification signed and witnessed this 25th day of July, 1888.
