-WASHER-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 430,892, dated J' une 24, 1890.

Application filed October 80, 1889. Serial No. 328,667. (No model.)

To @ZZ whom t may concern:

Be it known that I, SAMUEL J. SHIMEE, a citizen of the United States of America, residing at Milton, in the county of Northumberland and State of Pennsylvania, have invented new and useful Improvements in lVashenMaking Machines, of which the following is a specification.

My invention has relation to improvements in machines for punching metal washers from a plate or bar fed to the machine, and the object has been and is to simplify and improve the mechanism involved in that certain machine whercon Letters Patent for the United States of America were granted to me under date of November 13, A. D. 1888, No. 392,886, for improvements in machines for making washers, and the objects are accomplished by means of the mechanism, construction, and combination thereof shown in the accompanying drawings, wherein Figure 1 is a perspective of my newly-invented and improved washer-machine. Fig. 2 is a front view in elevation of the saine, the front plate of the punch-head box being removed io show the punch-head and block. Fig. 3 is a side view. Fig. 4 is a central vertical section of the same, taken from the front to rear on the line a; of Fig. 2. Fig. 5 is a plan view of the bedplate, showing the shifting plate, the clearer-bar, and one of the spring-washer pickers, the others of the lastnamed elements being omitted because their` multiplication would merely show them in repetition. Fig. G is a view of the improved die. Fig. 7 is atop plan view of the same. Fig. 8 is a bottom view thereof. Fig. 9 is a vertical central sectional view of the die and a view of the detachable diering. Fig. 10 shows side, top, and end views of the washerpicker. Fig. 11 is a vertical central section of the die, detachable die-ring, and washers in the die, with the central punch held in the washers, and a side view of the washerpicker, showing the relation of the parts as dropping a made washer from the bottom of the mass in the die. Fig. 12 is a bottom plan view of the die-bed, showing the seats for the elastic cushions and guide-pins. Fig. 13 is a detail sectional view of the die-bed, taken on the line y y of Fig. 12, and showing the die removed in elevation from the seat in the diebed. Fig. 14 is a perspective of the rocking arms for reciprocating the shifting plate or bed underthe dies. Fig. 15 is a perspective of the keeperplate which lies over the diebed to keep the plate from which the washers are punched from buckling or lifting, guideholes for the punches being arranged therein on an oblique angle to the front of the ma'- chine. Fig. 1G is a perspective ot the beds piece carrying the washer-pickers.

In my former patented invention, as well as in the present invention, the object is to perfeet a machine which makes the washers from above the bed and delivers the cut washers below in the direction of the cutting stroke of the punch, and, while I have in the present instance shown and described an improved mechanism generally, the gist of the invention involving my improvements is included in and about the dies of the machine.

Referring to the drawings, A designates the bed ot the machine, consisting of a strong and substantial casting having a seat or -bed at 'the front to receive the different parts of the die elements, as will be hereinafter fully specified.

The bed of the machine is extended rear ward, as at 1, and at the front has formed on it and projected vertically from it a strong lstandard 2, formed with a hollow punch-head box 3. On the rear of thebed is a standard l, carrying a sleeve 5, in which a bearing is arranged, and in the rear of the standard 2 is a bearing G, in which bearings are mounted a driving-shaft 7, carrying a ily-Wheel 8, two band-pulleys 8X 9, of different diameters, toprovide means for driving the machine at different speeds, and a small gear-Wheel lO. In the top of the standard 2 is formed a sleeve, in which is arranged a shaft 11, the outer end of which has a bearing in the plate covering and closing the front of the die-head` box, as at 12, and on the rear of this shaft is mounted a large geaiwheel 13, meshing with the small gear-wheel l0 on`v the driving-shaft. On the shaft 11, in a suitable recess in the die-head, is an eccentric 14, having loosely mounted thereon a wedge-shapedblook 15, by means of which the die-head is reciprocated, as hereinafter specified. In thediehead box is arranged the upper section 16 of the reciprocating die-head, fitted in` the box.

and formed with an opening 17 to take the wedge-shaped block and large enough to permit its free movement. In the lower part of this section 16 is a transversely-arranged recess 18, into which the opening containing the block opens, as at 19, and in this recess is a shifting rack 20, having a rack 21 on its upper face, and at the end is formed with an upward-projecting piece 22. ln the end of the recess 18 is a small gear-wheel 23, having its journal extended beyond the face of the punch-head block and provided with a crankhandle 24. By turning the handle the gear engages the rack on the shifting rack and moves it until the projection thereon comes directly under the end of the wedge-shaped block, when the cam is in operative position or condition to lift the punch-head. By mov-` ing the shifting rack back to the position shown in Fig. 2 the block is free, and its shaft may turn and it move without moving the punch-head. The lower portion of the section 16 of the punch-head is made smaller than the upper portion, as at 25, and formed with grooves 26 in its side faces to take tongues on the lower section. The lower section 27 of the punch-head, carrying the punches, has upwardly-extended side pieces 28 29, formed with tongues 30, engaging the grooves on the upper section, and the parts being united, as shown in Fig. 2 of the drawings, they are additionally secured by means of headed screw-bolts 31, let into their spliced edges. The lower part ofthe section 27 is chambered out, as at 132, and projected forward, as at 32, and formed with punch-seats 33, arranged in oblique direction to the front line of the head. The punchseats have openings 34 leading from them through the head, through which the chips of the center of the washers are discharged, and, sliding down the incline, are caught in a trough 35 and carried thence to a receptacle, as shown in Fig. 1 of the drawings. In the die-seats of the head are fixed the dies 36.

Over the front of the die-head box is secured a plate 37, having an aperture 38, through which the journal of the small gear operating the shifting rack projects, and at the upper end of the plate is the bearing 2, in which the one end of the shaft l1 in the upper part of the machine is mounted. In the recess 132 of the pun ch-head are fixed inclined clearingplates 39, having their upper ends lodged against a stud, as shown in Figs. l and 4 of the drawings, and their lower ends arranged just clear of the inner edges of the punchopenings. These plates serve to throw the center chips forward as they rise out of the holes, and thus free them from each other and keep the punch head comparatively clear.v Over the die-head box is secured a bridge-piece a, through which are projected two vertical standards b, the lower ends being secured to the die-head, and having on their upper ends heads, as shown. projecting portions of these standards are ar- On the ranged springs c, the force of which act as a cushion and relieves the die-head from jars and tends to raise the die-head toits highest position.

The front of the bed of the machine is formed with two substantial bench-pieces 40 41, in which are set vertical guide-pins (not shown) to engage the guide-holes in the diebed plate. The benches also have formed in them seats, (not shown,) in which the elastic cushions or supports are arranged. On these bench-pieces is arranged the die-bedplate 42. (See Figs. 12 and 13.) This plate is provided with pin-holes 43 to set over the guidepins of the bench-pieces, and has cushionseats 44, in which the elastic cushions are arranged. In the die-bed plate are the requisite number of die-seats 45, one or more, as may be desired, andv grooves 46, leading to the dies, are made therein to take the backs of the washer-pickers. The die -seats 45 are shouldered, as shown, (see Fig. 13,) to take and hold the die.

B designates the die. This is preferably made of two parts of an exterior conformation to be seated in the die-seats of the die-bed, and to this end l have shown it consisting of a main die or shell 48, having an upper part 4.9,of larger exterior diameter than the lower portion, to set in the shouldered recess of the die-seat in the bed, and having the lower por- Ation 50 to fit the lower part of the die-seat.

This lower portion'is provided with open-end slits or slots 51, the purpose being to make this part of the die have a limited spreading function, tending to grasp the washers with a slightly-yielding grip. The lower end of the die is enlarged, as at 52, so that the washers will be free from contact with the die when they reach that part and be in condition to be engaged and separated by the washerpicker. When the picker is used,the die has an opening 53 in its side, through which the picker projects to engage with the washers.

In the upper part of the die-shell is formed an annular seat 54, in which the die-ring 55 is arranged, as shown. In the upper part of the die may be a key-slot 56, in which a threaded bolt or key may be inserted to key the die in its bed, and in the edge of the shoulder of the die-shell is a notch 57, extending under the die-ring, which affords means for inserting the end of the hand-piece to knock the ring-die from its seat when desired. By making the die of an outer and lower part and a ring-die seated therein, as shown and described, I attain the desired object of having a die combining the elements of great strength and superior cutting quality, the shell being of the strongest steel and tempered for strength, and the cutting-ring die being tempered for cutting purposes. Thus if the ring-die becomes dull and breaks, it can readily be replaced bya new one or taken out and sharpened.

' Across the face of the die-bed is arranged a keeper-plate 58. (See Fig. 15.) This-plate der it and over the die-bed.

is arranged far enough above the surface of the die-bed and dies to allow the bar or plate from which the washers are made to pass un- It serves to keep the bar or plate in position for punching and prevents it from buckling orlifting when the punches are withdrawn. In the keeper-plate are the requisite number of holes 59, through which the punches 36 enter to engage the bar below.

In ways in the benches of the bed of the machine is mounted a shifting or reciprocating clearing-block (i0, having its cleaiing end 6l arranged at an angle, as shown, and in the bed over this shifting block is fixed a clearing-bar (32, arranged parallel with the clearing edge of the shifting block. On the bottom of the shifting bleek are formed downward-projecting teeth or lugs 63, which are engaged by seats in arms 64C on a rock-shaft or sleeve (55, mounted in the base of the bed of the machine. (See Figs. 1, 1i, and 14.) The rock-shaft is extended through the side of the frame of the machine, and has connected to it an arm G6, the free end of which is connected to a rod G7, which at the other end is connected to a lever G8, mounted oni-a fulcrumpin 69. The upper end of this lever engages in a race in the face of a wheel 7l, mounted on a shaft in a bearing 72 on the side of the machine, which shaft has a gear-wheel 73 on its end, which engages a wheel 74: on the shaft in the top of the machine. The race in the wheel 7l is given such an angle as to eventuate through the lever and rod connections to the rockshaft in throwing the shifting block the requisite distance back and forth under the end of the dies.

At the front of the machine, under the diebed, is arranged the bed-piece 75 (see Fig. 1G) of the washer-pickers. On the outer straight edge of this bed-piece is a vertical flange 7 G, having the requisite number of holes in it to rake and hold the stems of the washer-pickers. The inner portion of this bed-piece is ared inward, as shown, and is formed with a requisite number of T-slots 7 7 to take the washerpickers. The washer-pickers 7 S are formed with blades or flat heads 79, having side flanges at their lower portions to engage the Tslots, and have stems 8l extended and projected through the holes in the flange on the bed piece, the projecting ends being threaded and provided with nuts to hold them in position. On the stems are arranged springs 82, the force of which pushes the heads of the pickers constantly inward. The picker ends of these wash er-pickers are formed with a picking-point 83 and steps S4: S5, the former of which gives the picker play over the released washer, and the latter is made to give room for the play of the shift-ing block inthe bed of the machine.

C designates the center punch, consisting of a metal pinof the size of the center hole of the washer. It is made a plain cylinder of substantially the length of that part of the die holding the impacted washers, as at 8G, and at the lower end is projected a distance below the bottom of the die and made of smaller diameter, as at`87. It will be perceived by constructing the center punch smaller at the lower portion and chambering out the die at its lower portion the washer is freed from both elements when it reaches that position in its passage through the die and over the center punch. In the. passage through the die the washers become so iinpacted as to adhere to each other, and unless cleared of their impact would be delivered in such condition. To clear the punches and separate the washers, the washer-pickers are provided. These, as will be seen in Fig. tot the drawings, press continually imward, tending to loosen each bottom washer as it comes in contact with the end of the picker and entirely separating it when the point of the picker strikes the line between the washers, as seen in Fig. ll of the drawings. The punch C is held in position by the washers which surround it. When the dies or punches 3G descend, they carry before them the dies `B as far as the springs orv cushions on the die-seat will permit them to move and the punches 6 until they strike the shifting block GO, when they are arrested and the cut is made. Vhen the punches 30 are returned, the die-bed is forced back to its normal position by the elastic cushions on which it rests, carrying with it the dies B, which, by reason of their frict-ional engagement with the washers, raise them, and they in turn take with'them the punches C. Before the lastdescribed movements take place the pickers have separated the lowerinost of the washers, and when the parts return to their normal positions these separated washers remain upon the shifting block 60, and are by the clearing-bar 62 removed when the shifting block is moved.

D designates the feed mechanism, consist# in which are mounted a pair of feed-rollers 91` 92, the boxes of which are adjusted by setscrews 93, let through the plates on the top of the standards of the housing. In the middle of the respective rollers is formed an annular groove 94, which tends to accumulate the lubricating material and supply it to the plates as they are passed between the rollers to the punches. On the necks of the rollers are mounted meshing gears 95, (the lower one not being shown,) which turn the rollers to move with their contacting surfaces in the same direction to carry the bar in the direction of the punches. On the neck of the upper roller is a ratchet-gear 9G, which is engaged by a pawl 97, pivoted on one of the standards of the housing. On the ratchet, gear is eccentrically connected a pitman 9S, having its upper end connected and adjustably'held in a radial slot 99 in the gear-wheel IOO 101, mounted on a shaft journaled to the side I of the machine and meshing with the small gear on the main shaft in the top of the machine. This mechanism turns the ratchets 4one tooth at each rotation of the punch-shaft, and is arranged so as to push the bar forward in advance of the descent of the punch. At the rear of the feed-rollers is a trough 102, in which a lubricating substance is placed, in which the plates or bars are given a bath and then removed and fed to the rollers, a crank 103 being provided, by which the preliminary feed may be accomplished, and after the bar has been moved in the proper position under the punch the rolls feed it regularly.

Under the machine is arranged a receptacle 104, of any proper kind, to receive the cut washers.

I have herein described and illustrated a machine intended to carry more than a single punch; butit will be perceived that the principle of my present invention is equally applicable to a machine carrying a single punch, the purpose of the present illustration and description being to show the adaptation of the invention to machines cutting or punching more than a single washer at a stroke.

The operation is as follows: The center punch being arranged and fixed in the die, as heretofore specified, a bar or plate is given a plunge in the lubricator in the trough and then taken out and passed through the feedrollers and under the keeper-plate until in position under the punches. The machine then being in operation, the punches descend, cut out the washers, and when the die is full and the mass of washers project below the enlarged part of the die the pickers press the lower ones off. The shifting piece carries them against the clearing-bar, and they are shoved forward and dropped down through the opening in the machine into the vessel set to receive them.

Having thus given a description of my invention and of the manner of making, constructing, and using the same, and having explained the principle thereof and the manner in which that principle is carried into operation, so as todistinguish it from other invent-ions, I proceed to particularly point out and distinctly claim the parts, improvement, and combinations I claim as my invention, as follows:

1. The die herein described, consisting of a tubular shell provided at the lower portion thereof with open-end slots 5l, substantially as and for the purpose specified.

2. The die herein described, consisting of a tubular die-shell having an exterior conformation adapted to hold it in a seat in the die-bed, and formed with an annular recess in the upperportion of its bore and verticallyarranged slits in its lower portion,and a diering seated in its annular recess, substantiallyT as and for the purpose specified.

3. The combination of thereciprocating p unch,the die formed with vertically-arranged slitsin its lower portion, and the center punch having its lower portion of` smaller diameter than the body of the center punch, substantially as and for the purpose specified.

4. The combination, in a washer-making machine wherein the cut washers are discharged from the lower end of the die, of a bed-piece mounted under the die-bed and having a slot formed therein and a springactuated washer-picker arranged in said slot to push free the lower washers, substantially as described.

5. In a Washer-making machine, the combination of the bed-piece mounted under the die-bed and formed with a groove across its upper face, a spring-actuated washer-picker in said groove, a clearing-bar behind the die, a shifting-block mounted in ways under the die-bed, and means, substantiallyas described, for reciprocating the shifting block, substantially as and for the purpose specified.

6. In a washer-making machine, the combination of the upper shaft mounted in the top of the punch-head box and carrying' a gear-wheel, the shaft mounted in bearings on the side of the machine and having a gearwheel to mesh with a gear-Wheel on the shaft in the top of the punch-head box, a wheel having a cam-race in its face, a rocking lever pivoted to the side of the machine and arranged with its-upper end in the cam-race of the wheel and its lower end connected to a rock-shaft mounted under the front part of the machine, and a shifting block for delivering the Washers mounted in ways under the die-bed and connected to a rock-shaft, substantially as described.

7. In a washer-making machine, the combination, with the shaft mounted in the top of the punch-head box and provided with an eccentric, a wedge shaped block loosely mounted on the eccentric, a punch-head iitted to the interior of the punch-head box and formed with a recess to receive the Wedgeshaped block and a transversely-arranged recess in its face below the block and having an opening into the block-recess, a shifting block mounted in the said transversely-arranged recess and having a rack-gear on its face and an upward-projecting piece at its end, and a gear journaled in the recess in which the shifting block is mounted to engage the rack of said block, substantially as described.

In witness whereof I have hereunto set my hand in the presence l.of two attesting witnesses.
