DOWEL FORMING AND SETTING MACHINE.
srnorrrcn'rron forming part of Letters Patent No. 739,811, are September 29, 1903. Application filed March 3, 1902. Serial No. 96,505. (No model.)
To all whom, it may concern.-
Be it known that I, ALEXANDER BALDEN- WEG, a citizen of the Republic of Switzerland, A
and a resident of Schoenenwerd, Switzerland, have invented certain new and useful Improvements in Machines for Cutting Up Wire into Dowels or Rivets and for Inserting the Latter, of which the following is a specification.
This invention relates to machines for cutting up wire into dowels or rivets and for inserting the latter into the articles in which they are to be fixed.
According to the invention a pair of male and female dies or cutters are-employed, and the wire is passed between them through a suitable feed device. As each rivet is out 0d it drops into a hole in a slide which carries it to a pair of spring-fingers immediately over an anvil on which the work is supported. A suitablyarranged punch then descends and drives in the rivet.
The wire employed has a series of small disks or heads, and between these it has wide flattened and narrow unfiattened parts, so
that there is a flattened part on one side of each disk and an unflattened part on the other. This wire is specially prepared beforehand. y
The dies or cutters act on and cut through the flattened part, and as they are made of V shape the narrow parts are left with a plain point, whereas the wider flattened parts are split or forked and are left with a double point, like two fangs.
Referring to the accompanyingdrawings, Figures 1, 2, and 8 are corresponding views showing the working parts of the machine each at a different stage of the operations. Figs. 4, 5, and 6 are respectively a side view,
' an end view, and a plan, of the male die or cutter. Figs. 7, 8, and 9 are an end View, a section, and a plan, of the female die. Fig. 10 is a side view, partly in section, to a larger scale, showing the action of the dies. Fig. 1]. is an end view of the right-hand half of Fig. 10. Fig. 12 shows a piece of the special wire from which the dowels or rivets are cut. Figs. 13 and 14. are enlarged views at right angles, showing one of the dowels or rivets.
The machine comprises in the example shown a pair of cross-levers a a, hinged together at b and carrying at their lower ends the male and female dies or cutters o (1. These latter are held between clamping-disks e, secured by a screw 6. angular point or cutter c and the female die a corresponding triangular groove 03. The front edge of the latter die is also notched or recessed at d to receive the part of the wire that is to be cut. The die a is shown in Figs. 1, 2, and 3 in section on the line m to, Fig. 6, the die 01 being in central section.
The wirefis fed through a bracket or feedarm g, only thelower part of which is shown. In it are two channels g 9 the former for the wire and the latter for a feed-pawl g The wire is of the kindmentioned and is pro vided (see Figs. 12 to 14) witha series of disks or headsf, dividing it into sections and alternating with flattened parts f 2 and un flattened parts 1. The feed-pawl g is operated by any suitable means and at each stroke engages behind a fresh disk or head and feeds the next section of wire into position.
The punch for driving in the rivets is shown at h. It works through an aperture g in the feed-armand also through a slot in the die 0 and is operated by any suitable means. Its lower end is made hollow, as at h, Fig. 3, to fit over the rivet and bear solidly on the disk or head thereof.
The slide into which the rivets drop as they are cut oif is shown at t'. It has a hole i to receive the rivets and works over a plate j, having a'corresponding hole opening into a short tubej. A pair of spring-pressed fingers It are pivoted at it on this tube, their lower ends meeting below the mouth thereof. These ends are enlarged, as shown at W, but are recessed, as at le on their inner faces with the object of accommodating the rivet as it falls down the tube and retaining it until the punch descends and drives itinto the work I. The springs for these fingers are not shown, but may be of any suitable kind.
The work, which may be a piece of leather, is supported on the anvil orrest m, and when a rivet has been driven into it it is moved sidewise, Fig. 3, either automatically or otherwise to receive the next rivet.
The operation of the machine is as follows:
The, male die has a tri- The wire is fed into the machine so that its flattened parts f come below the disks f and lie across the path of the dies. In the position shown in Fig. 1 the feed-pawl g is just about to move the wire forward one step, so that the disk it is resting on will occupy the position of that immediately below it and the latter will be below the dies, as in Fig. 11. The dies are now brought together, Figs. 2 and 10, by operating their levers a, and the die 0 cuts through the Hat part of the wire just below the disk, (see dotted lines, Fig. 11,) leaving a double point, as in Fig. 14, below the middle disk and a single point above the lowest disk, which latter is thus severed from the wire and forced into the groove d. The dies then retire and the severed piece forming the dowel or rivet (seen to the rightin Fig. 10) drops into the hole 11, Fig. 2, in the slide. This latter then moves to the left and drops the rivet down the tube 3' into the spring-fingers It). Here it rests with its disk or head on the ends k of the fingers and its double point in the recesses k of said ends. The punch h is then caused to descend, Fig. 3, and by its impact forces open the fingers and drives the double points of the rivet into the work, the head f resting'flat on the latter.
. The shape of the double points causes them to diverge and spread, as in Fig. 14, so insuring a very firm hold even in thin material.
After the rivet is driven home the punch is raised and the feed-pawl g again operated. The slide 2' at the same time returns to the position shown in Fig. 1, and all is ready for the dies to act again and cut off another rivet.
These rivets or dowels are very suitable for use in the manufacture of boots and shoes for joining the innersole and welt to the outer sole. To this end a set of rivets are driven into one of these parts, as in Fig. 3, and the other part is then beaten or forced down onto the projecting points, whereby an invisible connection is obtained. The rivets may also be used in saddlery and bookbinding or for connecting pieces of leather, wood, or paper.
In order to increase the resistance, suitable notches or indentations are formed in sides of the rivets, this being done by roughening or indenting the wire when the disks and flattenings are being formed in it.
A convenient machine for producing wire formed in this special Way is described in the the combination of a feed-bracket having channels for the wire and for a feed-pawl, a reciprocating feed-pawl working in one of said channels, a pair of dies working below the mouth of said feed-bracket, a punch extending through said bracket and through a slot in one of the dies to prevent interference with the latter and a slide-plate for receiving the severed rivet and carrying it under the punch, substantially as described.
2. In a rivet cutting and driving machine, the combination of a feed-bracket, a reciprocating pawl acting on the heads of the uncut rivets, a pair of dies working below the mouth of said bracket, a punch for inserting the rivet, an independent slide-plate for receiving the severed rivet and carrying it under the punch, and a pair of fingers for bold ing, the rivet while being driven into the work, substantially as described.
3. In a rivet cutting and driving machine,
the combination of a feed-bracket having channels for the wire and for a feedpawl, a reciprocating, pawl working in one of said channels, a V-shaped male die having lateral flanges at the lower edges thereof, a female die grooved on its under side to receive said male die, a punch extending through a slot in one of the dies, and a slide for transferring the rivet from the dies to the punch, substantially as described.
4. In a rivet cutting and driving machine, the combination of a V-shaped male die having a slot therein, a grooved female die having its front end notched to receive the Hat part of the Wire and also forminga support or rest for the disk or head of the rivet, a .punch working through said slot in the male die and a slide to carry the rivet to the punch, substantially as described.
In testimony whereof I have hereunto set my hand, in presence of two subscribing witnesses, this 15th day of February, 1902.
ALEX. BALDENWEG.
