OLIVER EDES AND ANDREW HOLMES, OF BRAINTREE, MASSACHUSETTS.

MACHINERY FOR MAKING BIVETS.

Specification of Letters Patent No. 1,564, dated April 24, 1840.

To aZZ whom 2f may concern.'

Be -it known that we., 'OLIVER Enns and ANDREW HOLMES, of Braintree, county of Norfolk, and State of Massachusetts, have invented new and useful Improvements in Machinery for Making Rivets.

The said improvements, the principles thereof, and modes in which we have contemplated the application of the same by which they may be distinguished from other inventions of a like character, together with such parts, improvements, or combinations We claim as our invention and consider original and new, we have herein set forth and described, which description, taken in connection with the accompanying drawings, herein referred to, forms our specification.

Figures l, 2, 3, and 4 represent our improvements, Fig. l being an elevation; Fig. 2, a section; Fig. 3, a plan or top view of the same, and Fig. 4 some o-f the parts in detail or a section at a3 a3, Fig. 3.

A, A, A represents the framework of wood, metal or other proper material shaped and arranged as exhibited in the drawings, or otherwise 'suitably constructed to answer the intended purpose of supporting the operative parts of the machinery thereto attached.

B, B, is the main horizontal shaft Sup-- ported in suitable bearings a a on the top of the upright posts or standards C C'. On one end of the shaft B a drum pulley F, or crank D, Fig. 3, or other proper apparatus is to be affixed, communicating with the driving power.

E is a Hy wheel conveniently placed on the shaft B B, the object of the same being to concentrate and store the superfluous power and regulate the action or motions of the machine.

A cam G, Figs. 2 and 3, is fixed on the center part of the main shaft B B and so shaped that at each revolution of said shaft B B it will depress one end of the lever or curved lbeam H I J. The curved beaml H I J vibrates at one end J in bearings or supports Z) b, and is pressed upward, when the elongated part of the cam Gr ceases to act on the same by a powerful spring c CZ, one end Z of which is secured to the bottom plate of the frame, and the other c rests and presses against the underside of the curved beam H I J.

A crank or drum K, Figs. l and 3, is fixed on the end of the shaft B, B, and by means of a connecting rod L, whose other end is attached to the top of a lever M, communicates a vibratory motion .to a shaft N N, resting in bearings or boxes c c. Two ears 0 0 project from the shaft N N, and support in suitable bearings (Z CZ a cam roller P, see Figs. l, 2 and 3.

The roller P rests upon or against a curved surface e, e, or the rear of the heading carriage Q, and operates, while vibrated in an arc of a circle, by the vibration of the shaft N, N, so as to push forward the heading carriage Q, which is drawn back when the roller P rises by the counter action of a wound cylindrical or other proper spring R, Fig. 2. The heading carriage .Q is supported in suit-,able guides so as to allow it to move to and fro in a rectilinear direction, and carries the heading tool S attached to it by screws or in any convenient manner.

The rivets are cut from a cylindrical rod or wire of copper iron or any other metal suitable to t-he purpose, which rod is supported as it passes between the cutters, on or by a piece .of steel f g Figs. l, 2 3, 4 .whose end g Figs. 2 3 and 4 is bent upward a little at right angles, and has a semicircular guiding groove L cut therein, the said piece of steel being aiixed in a blockV of metal T Figs. l 2 3, 4. The arm or beam AH I J carries atlixed to the end H, t-he steel cutter z' 7c, whose lower end (see Fig. 4) isI hollowed out'semicircularly to receive the wire as it passes between it and the edge of the resting block or piece of metal f g. The wire or rod is fed in by the operative,

until it strikes against thevface of a step or standard U Figs. l 3 and 4, when the beam H I J carrying-the cutter z' la is brought down and separates or cuts off that portion of rod which intervenes between the outer yedge g of the block f g and the face of the standard U, and the piece so separatedl falls on the upper face of an arm or linger V, Figs. l, 2, 3, 4.

A stud IV, Figs. 2 and 3, projecting from the heading carriage, meets and pushes forward (when said carriage advances) the ex- A tremity of a bent lever X Y Z whose ful crum, or points of support, is at Y. The opposite end Z of the lever presses outward Athe top of an upright Z, m, Figs. 3 and 4, who-se lower end or foot is supported and vibrates in a proper bearing or joint n, at tached to the bed of the frame.

The arm V before mentioned is Supported at one end in a proper manner at b3, Fig.`4, by the upright Z m. As the upright Zmis forced outward by the bent lever X Y Z it is returned when the heading carriage recedes,

by the counter action of a sprmg 0 p, Figs.

3 and 4. That portion of the wireV which was cut 0H (and heretofore described as resting on the upper face of the arm V and nipped or held byitand the end V of the cutter i lc, see Fig. 4) is no-w carried down-4 ward by the further depression of the arm or beam H I J until it arrivesV opposite a cylindrical aperture g 9,.Figs. 2 and 4, into which it is driven by the heading tool S of the advancing heading carriage Q, Fig. 2. This apertureV is not quite so long as the portion of wire cut oif to be formed into a rivet, just so much of the said portion as is necessary, for the formation of the head projectingfbeyond the face of the block T. As the heading carriage advances the tool S, strikes upon the projecting metal and gives it the requisite shape for the head of the rivet. Then as the carriage Q recedes the spring s t, bearing on the underside of the arm V, raises the-arm V up to its former po` sition to receive the neXt portion of wire j separated by the cutter. The rivetsoformed is pushed out of the aperture Q 1 by the action of the piston u o Figs. 2 and 3 which is connected or joined to the end of a lever w jz/ and driven forward by said lever when the beam H I J rises. The operation of the same is as follows. The lever vibrates on a pin or fulcrum m. The end e of a long bar a a abuts against or is connected to the end y ofthe lever 'uy' m y, the opposite end of said bar being connected to the lower part of the upright lever M, which projects downward below the shaft N N to the end of which it is attached. Thereforethe vibrations of the 4lever M will cause the bar e a. to press forthe standard Z m `(see Figs. 3 and 4) at the same time withdrawing the end of the arm V from` under the rivet; which arm immediately flies upward bythe counter action of the spring s t.

Having thus described and set forth the nature and principles of our improvements and exhibited them in the annexed drawings i 2; Ve claim the combination of the cutter z' 7e and arm V for pinching or nipping the piece of wire separated by thecutters, `and conveying it downward (by descent of the cutter z' 7c) to the aperture g 1' to be headed by 'the headingmachineryrand we claim that combination and arrangement of the parts, for .withdrawing the arm V from under the head of the rivet inthe aperture Q 1,"the said combination and arrangement consisting of the bent lever X Y Z, the standard l m spring o p connectedto the shelf or arm V, and operated `by a stud or projection W from the heading carriage sub-V stantially in manner above described.

.8. We claim the combination of machinery, (consistingof an upright lever M bar a e, lever w w 'i/ and piston u o operated by a crank K on the main shaft B B and connecting rod L) for forcing or pushing out the rivet from the aperture g 1 after the heading machinery has performed its office.

In testimony that the above is a true description of our said invention and improve.- ments, we have hereto set our hands this twenty-fifth day of January in the year eighteen hundred and forty.
