Specification of Letters Patent.
Patented Aug. 29, 1905.
Application filed February 1, 1905. Serial No. 243,620.
To all whom, it may concern:
Be it known that 1, WILLIAM F. DOWER- MAN, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Kicker- Plates for Rivet-Machines, of which the following is a specification, reference being had therein to the accompanying drawings, form ing part of the specification, in which I Figure 1 is a face view of my improved kicker-plate in position in the breast-plate of a rivet-machine. Fig. 2 is a horizontal sectional view through the operative mechanism of the machine, showing the kicker-plate in position, the section being indicated on the line II II of Fig. 1. V Fig. 3 is a vertical sectional view indicated by the line III III of Fig. 2. Fig. 4 is a perspective detail view of the kicker-plate detached.
My invention refers to improvements in machines for manufacturing rivets, bolts, 800., wherein the heated bar is fed into the machine, sheared off, clamped between a stationary and a movable die, headed while so held, and then ejected after withdrawal of the header and the movable shear and clamp.
The present invention refers to improvements in the kicker-plate carrying the stationary cutter; and it consists in the construction of the plate by which it is immovably mounted in the breast-plate of the machine and clamped therein in such a manner as to fixedly hold and retain the cutter.
Heretofore devices of this character have been made circular in form and provided with a plurality of, usually three, openings and cutter-plates and a corresponding number of openings for the kicker; but a common objection to a circular cutter-holder is that it is very diflicult to retain in the proper position in the machine, so as to prevent turning or displacement under the severe continuous operation to which this class of mechanism is usually subjected.
My improved device is made rectangular or polygonal in form, so as to be seated in a correspondingly-formed socket in the breastplate. Itis provided with a single cutter mounted in a circular-shaped opening, one side of the plate being cut through, so as to provide for clamping the cutter, and the entire device and cutter are rigidly and immov ably secured in position by a tapered key.
Referring now to the drawings illustrating the invention, 2 is the breast-plate of a rivet- L machinein the front face of which is mounted stationary die or clamp 3, against which the blank is moved and held after shearing by the movable shear and clamp 4, which has a reciprocating motion in front of the breastplate and kicker-plate. Each of the dies or clamps 3 and 4 is provided with a half-round opening 5, forming when closed, as in Fig. 2, L a cylindrical embracing two-part aperture in which the blank 6, sheared from the rod 7, is held. The head is formed by the header-die ;8 while the blank is thus held, and after the header-die and shear 4 have receded the finished rivet is then forcibly thrown out by the kicker, consisting of a reciprocating pin 9, passing through a suitable opening in the breast-plate and actuated by any suitable gmechanism, as a lever 10, operating in suitiable conformity with the other moving elements of the apparatus.
11 is the kicker-plate seated in a recess 12 in the front of the breast-plate flush with its outer face and in line with a rear aperture 13, through which the blank-rod 7 is fed. The kicker-plate is provided at its central portion with a cutter 14, having a central aperture conforming to the diameter of the blank made of hardened steel and adapted to act as a stationary cutter against which the blank is sheared by the movable shear 4. The cutter 14 fits snugly within a receivingaperture in the plate 11, and the plate is out through or slotted at one side, as indicated at 15, by which the opposite portions of the plate may be brought more closely together or in binding contact with the cutter. Such binding adjustment is secured by a tapered pin, key, or wedge 16, driven down through a suitable opening in the breast-plate and engaging a tapered recess 17 in the edge of the plate, as clearly shown. Such tapered pin not only firmly binds the plate in position upon the breast-plate, but also compresses its sides tightly together by reason of the slot 15 engaging the cutter 14 and effectually preventing its removal or displacement. The kicker-plate is provided with an opening 18 to one side of the cutter, as shown, through which the-kicker 9 projects to eject the finished rivet.
The cutter 14 is of an exterior diameter and of suflicient size to permit of its being enlarged interiorly when worn for the next larger size of rivet. By this provision cutters made for a small diameter of rivet may be successively used for several increasing diameters.
The advantages of the invention consist particularly in the fixed immovable character of the kicker-plate and cutter, the solid unyielding bearing under the shock of the header-die, the ease and facility with which the parts are taken out by merely removing the tapered pin, and the high efiiciency during continuous operation. stood that the plate may be of other forms than rectangular, it being only essential that it shall be of some other form than circular, so as to provide a good area of bearing-face under the pressure of the heading-die, and that it will resist any tendency to turn.
Various changes may thus be made in its construction or details by the skilled mechanic without departure from the inven tion; but all such changes are to be considered as within the scope of the following claims.
What I claim is- 1. The combination with the breast-plate of a rivet machine, of a polygonal kickerplate provided with a cutter-recess, divided at one side of said recess, and having a tapered key-seat along one of its edges, and a tapered securing-key therefor, substantially as set forth.
It will be under-- 2. The combination with the breast-plate of a rivet-machine, of a rectangular kickerplate provided with a circular cutter-recess, divided at one side of said recess, and having a tapered key-seat along one of its edges, with a tapered securing-key therefor adapted to clamp the kicker plate upon an in serted cutter, substantially as set forth.
3. The combination with the breast-plate of a rivet-machine, of a rectangular kicker plate divided at one side and provided with a circular cutter-recess and bearing-flange, a circular cutter mounted in said recess and against said flange, and a tapered key-seat along one edge of the kickerplate' adapted to provide a bearing for a tapered key, sub stantially as set forth.
4. A rectangular kicker plate provided 55- with a circular cutter-recess and divided at one side thereof, with a kicker-pin opening at one side of said recess, and a tapered keyseat alongthe edge of the plate at the other side of said recess, substantially as set forth.
5. The combination of a rectangular kickerplate provided with a central circular cutterrecess and a bearing-shoulder, a kicker-pin opening at one side of said recess, a tapered key-seat along one edge of the kicker-plate, and a circular cutter mounted in said recess and adapted to be clamped therein by a tapered key, substantially as set forth.
In testimony whereof I afliX my signature in presence of two witnesses.
WILLIAM F. DOWERMAN. Witnesses: JOHN FINK, J. W. FINK.
