No. 375,725. Patented Jan. 8,1888.
UNITED STATES PATENT OEEIcE.
GILBERT W. BRADLEY, OF SUNDERLAND, VERMONT.
RIVETING-MACHINE.
SPECIFICATION' forming part of Letters Patent No. 375,725, dated January 3, 1888.
Application filed May 10, 1837. Serial No. 237,702. (No model.)
To aZZ whom t may concern:
Beit known that I, GILBERT W. BRADLEY, of Sunderland, in the county of Bennington and State of Vermont, have invented an Improved Riveting-Press, ofwhich the subjoined description, in connect-ion with the accompanying drawings, constitutes a specification.
The Inaehine is intended to be used in riveling together the ends of metallic bands or hoops. Itis fully shown in perspectivein Figure l of the drawings. Fig. 2 shows the under side of the punching and heading die; and Fig. 3 exhibitsthe method of using the machine,and shows the relative positions ofthe two guidecheeks E and F.
The mechanism is mounted on frame A, and consists of the two principal punching and heading dies b and Q. The die Q may more properly be called an "am/il, and is imposed on the block D. Its upper surface consists of a. plane face, with the possible exception of a depressed circular seat, s, whereon the rivethead is laid point upward. Pivoted to block B is the lever H, the fore end of which carries the punching and heading die or plate b. Said plate is better shown in Fig. 2, the end of the lever being inverted for that purpose. perforated with a punching hole, b', which works over the point of the rivet in precisely the same way as the sheet-iron workers punch operates. More properly itis a die-plate, the rivetitselfforming the punch. Olosebeside this is the countersunk header g, which is merely a concave depression designed to head down the protruding point of the rivet and leave a smooth convex finish. The two parts D and H lie between the two cheeks B B, between which the cam-lever O is also pivoted at e. The rear end of lever O is connected with foot- -lever P beneath the machine by means of rods L L. Foot-lever l? is pivoted to rear leg of frame at A, and is connected with platform of frame by retractile spring S. The slotted link I connects the cam-lever Owith the lever H, and performs the office of lifting lever H whenever the cam-lever O is pushed up by the retraction of spring S. The depression of foot-pad R effects the closing of the header b against the anvil Q. v
The office performed by the guide-cheeksE It is and F is shown in Fig. 3, and will appear by describing the use of the machine. Guidecheeks E and F are weighted at their rear ends, so that they normally bring a shoulder up against cheeks B B. In use the hoop or band J is first eut to a denite length. then laid on spot s, head down. One end of the band is then set in between the jaws of the header and brought into contact with the left guide-cheek, t. Theotherislaidin over guidecheek t and 'abuts against guidecheek F. Header b is then brought down over the rivet, which is forced through the metal, the chips passing up through aperture'b'. Thus the hole is made and the rivet inserted therein. Then the hoop is moved a little to the left and the lever again brought down, whereby the rivet is headed under header g.
The die b and anvil Q are old; but the swinging or pivoted guide cheeks E and F are thought lo be new, and the function they perform in connection with the riveting-jaws is as follows: When at rest, the guide-cheek t is at an elevation, where the end of the hoop carried under cheek F will readily find abutment against it. The other end of the hoop or band will of course rest on top of cheek t at the right elevation to allow it to clear the top of the rivet, and its end will find abutment againstinner edge of guide-cheek F. Then the header is brought down, the guide t yields or descends, as it also does when the rivet is headed by the second movement.
I therefore claim as Iny invention-- The combination of the vertically-movable header b, having dieperforation and heading former or countersink, and the anvil-plate beneath, having aspot or seat forthe rivet-head, with the lateral swingingguide cheeks or stops E and F, and means for imparting to the header a reciprocal Vertical movement, as and for the purposes specified.
In testimony whereof I have hereto set my hand, at Sunderland, Vermont, this 23d day of August, A. D. 1886.
GILBERT W. BRADLEY.
In presence of FRANKLIN SCOTT, EMILY SCOTT.
