Lette/rs Patent No. 95,700, dated` Octoberl 12, 1869.

IMPROVE!) MACHINE FOR WIRING- RING-IES.

The Schedule referred to in these Letters Patent: and making pari: of the name.l

To all whom it may concern Be it known that I, ELLIS LUTHER, of West Troy,

in the county of Albany, and State of New York, have invented an Improved and that. the following is a full, true, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a perspective view of a machine coutaining my said invention;

Figure 2 is a view of the same, from above; i

Figure 3 is a section of my saidmachine, showing the manner in which the hinge is held duringthe process of wiring; n p

Figure 4 is another section of my said machine,exhibiting the mode of conveying Ythe 'wires from the hopper to the groove, ii'om which they are forced into the jointslof the hinges;

Figure 5 is a section of my said machine, through the groove above mentioned;

Figure 6 exhibits the construction of the revolving cylinder, hereinafter described;

Figure 7 shows one of the wires; and

Figure 8, the separate parts of a hinge.

Figure 9 represents the shaft and plunger, bywhich .the wire is forced through the joints of the hinge and Figure 10, the manner in which the plunger maybe supported vby sliding blocks, as hereinafter described.

Having stated the natureof my said invention, I

will proceed to describe the construction and operation thereof'.

A is a strong frame of wood or ports the shafts B and C.

As shown in the drawing, the shaft B .is actuated by a crank, but it is my intention to have it driven by steam or other power.

`Motion is communicated from shaft B to shaft (i, by means of a bevelled gear, as shown in iig. 2.-

At the end ofthe shaft yB is attached, in the usual manner, the reciprocating shaft I), to which is attached the plunger I.

The said reciprocating shaft, 'below' the joint, at X, slides in a frame, Y Y

K is the stationary and L the movable jaw of a vise, which opens far enough to receive the joint of a hinge.

At the place where the hinge is inserted and held the jaws are constructed with plates of steel or other `suitable metal at their upper surface, which plates project toward each other, slightly beyond-the body of the jaws.

metal, which sup- The said jaws, under the hopper or Ireservoir, each` contain a small semieircular groove, half the size of the wire to beused, so that when the vise is closed, the two grooves will'form a circular passage the size ofthe wire aforesaid. This groove is upon an exact Machine for iViring Hinges;

line with the joint of the hinge, when placed Vin the y.

l vise, and with the plunger I.

J is a platform under that portion of the ymovable jaw in, which the groove is constructed, and its top is just even with the bottoms of the grooves, so that ifr a wire is dropped on the platform between the jaws,

it will, when the jaws-are shut, be enclosed in the circular passage formed by said grooves,fas aforesaid.

The shaft CY carries the cams S S, which, at 'each revolution, close the vsie by forcing the movable jaw L against the stationary jaw K.

After therv cams have ceased to act upon the said movable jaw, itis drawn back to its former positionby the weight l and cord h, which passes over the pulley t.

j M is a species of hopper, whose width is but a trie greater than the length of the wires to`be used.

The bottom of this hopper slopes from each end' to' an oblong aperture, near the centre, to which is closelyj tted the surface ot' the revolving cylinder O, as shown', l

in iig. 4.

In the surface of this cylinder is constructed the longitudinal channel or recess a, of just snicient size to hold a single wire.- y

The cylinder revolves in a kind ofdrum, N, which contains, at the bottom, an aperture, c.

P is a plate of metal, fixed upon the movable jaw under the hopper, and having the oblong yrecess i;of sutlicient dimensions toadmit a single wire.

lhe cylinder 0 is revolved by means ofja band passf ing over the wheels R It.

V is a projection on one ofthe cams, which, at each revolution, strikes. the arm 1^ .of the compound level' W and depresses it, 'thereby elevating the arm p of said lever, for the purpose hereinafter mentioned.

c is a spiral or other spring, which brings the said lever' back to its former position after it has been actuated by the-cam and projection V, as aforesaid.

i] g are small blocks, made to slide in the frame Y Y, for the purpose of supporting the plunger I, and are attached by the chain n n to each other and to the shaft. They may be employed in any number desira. v ble, which will not interfere with the necessary length l of stroke. f f

The mode 'of operation of fmy said invention is as follows:

The hopper M is first filled with wires, piled across the hopper and parallel with the cylinder O.

The shaft B is then put in motion, causing the shaft C and the cylinder O to revolve.

As the cylinder O revolves, bringing the recessv u under the opening in the bottom of the hopper, one of the wires will drop into the recess c and will be carried round with the cylinder until it reaches the aperture c, in the Vdrum N.

At this moment the movable jaw L iS forced toward the stationary jaw K, by the operation of the cams S S, and the recess f, in the plate P, is brought directly under the said opening c, aud the wire drops into the said recess f from the-cylinder O. Y

The wire is retained in said recess f until, by the continued revolution of the shaft G, the cams S S release the movable jaw L, which is immediately drawn back by the cord and weight T, allowing the wire to drop on the platform J.

At this moment a hingeisplaced in thevise in such a manner that the joint of the hinge is between the jaws and so that edges of the metallic plates L K will grasp the upper surfaces ofthe joint on each side close to the leaves ofthe hinge, thus holding the hinge firmly by the joint, and preventing-the slightest motion.

As the jaws are thus closed, the wirc upon the platform J is enclosed in the double groove or cylindrical passage ll, the plunger I being suiiiciently drawn back to permit its entry into said passage.

Byvthe further revolution of the shaft B, the reciprocating shaft D is thrust forward, and the plungerA I, moving in the double groove or passage d, forces the wire into the joint of the hinge with perfect accuracy.

As soon as the insertion of the wire is complete, the cams S S againrelease the movable jaw L, and, as the vise opens, the projection V strikes the arm l of the compound lever W, depressing it and elevating the other arm, 11, so that the hinge is thrown out of the vise and falls into a receptacle provided for that purpose. Another hinge is then immediately fixed iu the vise ready to receive the next wire, which, by this time, is dropped on the platform J. Y

i By this means a wire is inserted at every revolution of the shaft B, and much more rapidly and accurately than can possibly be done Aby hand, and dispensing Y with a very large amount of manual labor.

As the plunger I cannot be larger than the wire to be inserted, it is obliged to overcome a great deal of y sage above mentioned, these blocks-will be forced to gether, but, when it is drawn back, they will be distributed along its length by means of the chain 71, and will eifectually counteract any deviation of the plunger from a right line.

What I claim as new, and desire to secure by Letters Patent, is 1 l. The combination and arrangement together, in the manner described, ofthe jaws K L, dischargingfollower e, and the mechanism by which the movable jaw L is advanced and retracted.

2. The combination of holding-jaws K L, with block J, slatted side P, recessed rotating cylinder O, hopper M, and reciprocating plunger I, all constructed and arranged as set forth.

` 3.v The receiving-plate J and movable jaw L, in combination with the slatted side P, the recessed rotting blank-feeder O, and hopper M, all constructed and arranged as specified. v

4. The construction and arrangement, with thereciprocating plunger I, of movable'rest-blocks g, andl chains n, as and for the purpose specified.

In witness whereof, I have hereunto set my hand, this 2d day of February, 1869.

ELLIS LUTHER.
