` l I "Be Iit known `thatfI, '.JERELMY. TAYLoRJioBD, 'of -thecityandcounty of SauvFrancisco, State of Gali- I fornia, have inventedan It'nprovedMachine for Mak ging Hooks and Eyes;` "and I do hereby declare the `following description land accompanying drawingare sufficient to enable any person skilled in the art or I Iscieuce` to which it most nearly appertains, to make `and -use.my said invention or improvement without I further invention or experiment. I

lheobject of 'myinvention is to provide Ya vmachine `fr'iruiaking]hooks and eyesfortoilet 'use directly from the reeledwire, one of each kind being made at each" revolution' of `thedriving-.wheel, and completed ready for use, I`

I Referring totheaccornpanying drawngfor'a` more 4complete'description of my invention-- Figure 1 is aIplan viewIof` my improved machine.

v `Figure 2 is a planoflthe bed on which the hook is Figure `3ds al side elevation. u u `Figure 4`is an-nd View@ I l `Figures 5 and 6` arerdetailed views of parts of theV gmacphinc.` I

A is the franje supporting thedifferen't parts of the B is a-shaft-extending across the frame, near its iuiddle, and having `its endssupported in boxes C C.

vA driying-pulley, D, at one end, communicates mo- `tion tothefshaft,.anddl'orn` this the whole machine `is operated; f

The wire for forming the, hooks is brought from a reel, not shown,and passes between two rollers, E E,

Iwhich press it sniiidiently feed it forward when they In order to rotate them Ia mutilated bevel-gear, I,

I` or other equivalent device, is. made fast `to 'the shaft B, land the fewv teeth upon it engage' withpthe pinion l Gr` upon one of ttlIerollersIE at each revolution, thus `turning the rollers Esufliciently to feed forward the I I quantity of wire necessary `for one hook.

Spur-pinions H oneach of therollers insure their As the wire Iis carredsforward itpasses through eyes or holes at 11', and across a bed or table, .T,`bcing p `previouslystraightened byfsuitable devices. I

A cutter, K, isniovcd forward by a cam, J', on the A shal'tIB, and sevcrsfthe wire, leaving sullicient for one hook lying across the table J. V

`The p middle Iof thewireilies exactly opposite the narrow space orslitformed `between the 4plates L L, which form a part of the table J, orInay be bolted to it; These plates 4are suicicntly wide apart to just allow I `the wire to pass between them, another platcM, bc,-4

ing arranged to slide over the whole and keep the wirefroIn rising out of theslot or groove before described.

As the machinery moves on, a narrow plate, N, which passes vertically through the horizontally-slid ing plate-M and rests its lower end on the table J, presses against the center of the' wire opposite'the lgroove, andtbrcesthe wire to bend, so' that the'.blght thus formed shall be carried backward, and the wire,

thus doubledupon itself, will lie in the groove between the plates L' at. right angles with its former posItIon. I An inclined plane, O, is loosely pinned to the sta.

tinary frame, s o that a lug at one side ofthe plateN will In'ove over it, and when the wire has been carried back sufciently the lpg reaches the more abrupt rise in the plane. This raises the plateN till it clears the bight of the wire, and it InovesI back until it `passes beyond the wire, when it drops from. the rear end of the inclined plane and again rests upon the table J, but behind the bight of the wire.

lhc continued Inotion ofthe machinecanses the rplate M to slide forwardagain, carrying the plate N with it. The-lug passes under the inclined plane,as

it` Inoves forward, so that the plate N continues to slide with its lower end in contact with the table J,

and thus pushes the doubled wire before it.

The plate N is brought down and kept in contact with theftable, as it moves, byIsprings N', as showin The ends ot' the-wire Inove forward and enter another groove, also formed by two thin plates, P P, on

the table J, and a short .distance from the plate L.

lhe plate M, moving over and in close contact with r the plates P and L, prevents"L the wire from rising out ofthe groove.

At the forwardend of-thezlastmentioned groove u thc ends of the wire follow around the curves a. a, which are .there formed in the plates, thus forming lthe two loops by which the hoolis attached to the "lhe plate M is then -moved backward garment. again, leaving the partially-iiuishedA hook vexposedto vIcw.

at the proper point to forni the "loop, and presses the honl'g through the opening R.

As the punch reaches its lowest point a knee-lever, S, is operated by a cam,l, on the shaft l5, and the arIn w is ext-ended so as to press powerfully against the point of the hook and ila-tten it suliciently for servIce. I-

The ar'mu is then elevated and the punch Q raised, thus freeing the hook and allowing proper receptacle below.

`The punch is f rccd down and raised by means of a bent lever, U, t Ie opposite cnd'of` which is slotted. 'A pin, V, enters the slot-,from the sliding bar W,

IA punch, Q, is then broughtdown upon the wires it to drop iIIt-o a ,u

and as this bar moves forward and. backward it operates thc lever U to raise and lower the pnnch.

The plate M is bolted to the bar W, near one end, and is moved forward and backward by it.

' ,lhe center oi' the bar is formed, as shown, so that the cam or arm Xon the .shaft B will strike the end Y, as it passes above the shaft, to move the bar in one direction, and it presses against the endZ, as it passes below the shntt, to move the bar in an opposite direction. j

The devices for forming the eyes are situated, for convenience, at the opposite end ofthe machine from those which form the hooks, and operated from the same shaft B.

The wire for the 'eyes is brought from a reel, and passes through and between the posts b, by which it is straightened.

Theuce it passes through a` slot, between two plates, c c, which are iixed to a sliding carriage, d.

A lever, c, is pinned between the plates c, so that when it is pressed forward the lower end binds the wire, while the carriage is moved forward, thus carrying the wire with it.

In order to operate the lever and move the carriage a cam, j, is made fast to the shaft B.

'lhis cam strikes the end of a horizontally-moving level', g, at each revolution, and the opposite end ot' the lever slides the carriage d.

An arm, h, projecting up from the end ofthe lever' g, strikes the upper end ot' the lever e just before the carrier begins to move, and thus causes it to bind the wire, as before described.

The wire, being moved forward, passes across in front of a bar,. 7', going beneath two pointed rods, it',

one upon each side of a bar, k, as shown, the wire` passing overV this bar.

The end of the. wire stops against a post, l, when a cutter, m, moved by a cam on the shaft B, advances and severs the wire, leaving just enough for au eye.

The bar W, moving forward at this instant, carries with it a spring-bar, n, which is att-ached to it, and

this, with the shoulders of .the pointed rods i, forces the wire along sidewise.

The rod or bar 7c is formed with a gradual elevation, till at the end it takes the position shown in iig. 4.' The sides of the bottom plate are gradually turned up, as shown in the same iigure, so that as the wire is pushed along its center is raised and curved, forming,r the eye. The ends are turned over by the curving sides ofthe plate, so as to form the loops by which it is attached to the' garment, and when it reachesthe end of the' plate and rod k the finished eye falls off into a proper receptacle.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the u'ming-plates L and P with their grooves and the curves t (L, together with the sliding plates M and N, the incline O, and the punch Q, the whole operated substantially as and for the purpose herein described.

2. rlfhe combination oi' the sliding plate M and the looscly=attaehed inclined plane O with its springs N', or equivalent device, to raise the plate N and drop it behind the bight ot' the wire, substantially as herein described.

3. The combination of the sliding carriage d with the plates c and the peculiarly-shaped lever e, together with the vibrating bifurcated arm g, lug h, stub h', and the cam f, operatilig as described.

4. The combination of the bed-plate 1" with its gradually-curving sides, the pointed shouldered rodst t', and the curved rod k, together with the spring-bar n and bar j, for forming the eyes, substantially as herein described.

l5. In combination with the main shaft B and the reciprocating-bar W, the two sets of feeding devices and the two sets of forming devices herein described.

In witness whereof` 1 have hereunto set my hand and seal.
