MACHINE FOR MAKING COMPRESSED BUNGSL hil 'l-ECIPICATION forming part oi Letters Patent No. 336,652, dated February 23. 1886.

Application filed December 1-2, 1885. SerialNo. 185,505. (No model.)

To aZZ whom it may concern:

Be it known that I. EDWARD D. Mackin- TOSH, of the city of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Machines for Making Compressed Bu ngs, of which the following is a specification.

My invention relates more particularly to machines for making hangs in which the grain of the wood extends transversely to the axis of the bung.

In making such bungs with my machine a stick of wood is first sawed by a series or gang of saws into square blocks of about the thickness required for a hung. Such blocks are then fed through a suitable chute, whereby they are caused to descend, one after another, upon a rest or table in front of a tubular knife or cutter, and are then, by a reciprocating plunger, forced against and passed through the knife or cutter, after which the round blanks descend into a second chute and into a blank-holder, and are, by the action of a reciprocating compressing-die acting in con-' nection with a fixed die, compressed to give them the taper form desired.

In this machineit is necessary to provide against any accident by reason of the bnngs not being fed properly through the successive stages of the operation, and to guard against any derangement or breakage of the parts of the machine by reason of the bung-blanks being of a thickness greater or less than that usual, and also to provide for readily adjusting the parts of the machine to suit bungblanks of diiferent sizes.

My invention consists in a novel construction of the female compressing-(lie, which enables it to lift or move aside any bung-blanks which are unduly projected through the feeding-chute for round blanks, and in the combination,with such peculiar female compressingdie, ofa male compressing-die anda reciprocating or yielding basket or holder, into which the blanks are delivered to be acted upon by such dies.

The invention also consists in a novel conibination of parts, whereby the table or rest, which is supported at the lower end of the chute for square blanks, may be adjusted so as to bring the center of the square blank,

whatever be its size, always opposite the axis of the tubular knife which is to cut it into circular form.

The invention also consists in a novel combination of parts, whereby the fronts of the chutes for square and round blanks, which are supported so as to be free to move outward, either by swinging or otherwise, are caused to act upon a tripping mechanism, and thereby to throw off or release the drivingclutch through which the machine isoperated. V

The invention also consists in other combinations of parts, which are hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a sectional elevation of a machine illustrating my invention. Fig. 2is a plan thereof. Fig. 3 is a transverse vertical section upon the plane of the dotted line 00, Fig. 1, looking I toward the right hand of Fig. 1. Fig. 4 is a transverse section upon the same plane, looking toward the left hand of Fig. 1. Fig. 5 is a vertical section,upon a larger scale,i1lustrating the tubular knife and compressing-dies and portions of a chute through which the round blanks are delivered from the knife to a yielding basket or blank-receiver operating in conjunction with said dies. Fig. 6 is an end view of the blank receiver or basket and the male compressingdie. Fig. 7 is an end view of the female compressing-die. Fig. Sis a horizontal section upon the plane of the dotted line 3 y, Fig. 5, through the male compressing-die and the yielding blank receiver or basket, and a plan of the female compressing-die. Fig. 9 is an elevation of the lower portion of two side pieces which compose the chute for square blanks, the table or rest at the lower end of such chute, and a hanger whereby it is supported. Fig. 10 is an elevation at right angles to Fig. 9 of the parts shown therein; and Figs. 11 and 12 are respectively an end view and a side view of a sleeve and a locking and tripping lever which are comprised in the tripping mechanism of the machine. Figs. 5 to 12, inclusive, are upon a larger scale than Figs. 1, 2, 3, and 4..

Similar letters of reference designate corresponding parts in all the figures.

A designates a saw-arbor, which is supported jection.

by suitable bearings, a a, and on which are a series of saws, a supported and held at suitable distances apart by collars a The sawarbor and saws are to be driven by a belt run-.

ning upon a pulley, c

For cutting up sticks to producebung-blanks of different sizes the saws should be set at different distances apart, and provision is afforded for removing them from their arbor by first removing the outermost bearing, a, which fits in a dovetailed slideway, a, in the upper part of the frame.

Adjacent to the gang of saws a is arranged a trough or stick-holder, B,which is mounted upon arms I), projecting upward from a rockshaft,b,which is supported in standards If, projecting from the main frame 0 of the machine. The trough or channel B is notched at b to receive the saws a but when the gang of saws is differently arranged it is necessary to provide a channel ortrough, B, having notches b correspondingly arranged.

In order to provide for removing the trough B, and readily replacing it by another of different size, I construct it with dovetailed projections 12* upon its bottom, which enter dovetailed slideways in the upper ends of the arms b. as best shown in Figs. 1 and 8. The trough or channel B has at the side a handle, b whereby it may be swung backward and forward upon the rock-shaft b, in order to present the stick within it to the saws a From a point coincident with the inner end of the channel or trough B, when swung backward away from the saws, there extends a chute for square blanks, which consists of two side pieces, D, having upon their inner faces flanges d, which project toward each other and prevent the blanks from escaping from the chute. This chute is curved from a horizontal position at the upper end into a vertical position at the lower end, as best shown in Fig.

1. The upper ends of the side pieces, D, are

provided with hubs or eyes (2, which fit a horizontal stud or projection, d extending from the side of one of the bearings a, and by setserews d the pieces D may be secured at the desired distance apart upon such stud or pro- At their lower ends the side pieces, -D, of the chute are attached to blocks or slides D, which have at their back dovetailed projeetions d", fitting a correspondingly dove tailed slideway, (P, in a part of the framing C, and which may be adjusted toward and from each other by means of a rod or shaft, (2, having upon it right and left hand threads fitting corresponding nuts in the blocks D, as

best shown in Fig. 9. The screw (1 is provided with a hand-wheel, (2, whereby it may jacent end one of the side pieces D of the chute is provided with an inclined lip or projection, b, which is also shown in Fig. 2, and the trough B is notched at bite enable it to pass this finger or projection b. The finger or projection 1) forms an incline, which covers the projection I) when the trough B is brought back to the position shown in Fig. 2, and at its opposite side the inner wall of the trough B is flared outward, as shown at b.

In using the machine a stick of wood of proper size is thrust into the trough B until its end strikes the lip or projection I), when it cannot go any farther, and the trough is then swung toward the saws to cut the stick into anumber of blanks corresponding to the number of saws. The trough is then swung back to the position shown in Fig. 2, and as the incline I) enters the trough it cants or tilts the first blank sidewise and out of engagement with the shoulder b. The blank being short the flare or enlargement b at the opposite side of the trough enables it to tilt or assume such inclined position, and as the next stick is thrust into the trough the blanks will all be shoved from the trough between the side pieces, D, of the chute, each of the blanks as it reaches the incline I) being deflected sidewise, so as to pass the shoulder b. The arms I) may have toes 6*, which,by striking against the frame, as shown in Fig. 3, form stops to limit the swinging movement of the trough away from the saws. Adjacent to the lower end of the chute D for square blanks is a tubular knife, E, the axis of which is horizontal, and which has at the end cutting-projections, which givethe knife the common name of a fish-mouth knife. This knife is best shown in Fig. 5. It is held within a socket, e, and above and below it are auxiliary cutters e, which are held in place by set screws 6 and insure the division and consequent falling of the chips produced by the knife E, and prevent the machine from becoming clogged with chips. The inner end of the knife E rests against a shoulder, 6 in the socket e, and at the upper side of the socket is a spring-retainer, e, which bears up on the top of the blanks S, and serves to properly regulate their exit from the knife into a chute, F, which descends from the exitopening of the knife and socket. As the blanks descend in the chute D, they are brought one by one upon the table or rest G, which remains immediately below the chute, and about in line with the bottom of the knife E.

H designates a ram or plunger, which is fitted to suitable bearings, c, in the frame 0, and is operated by a connecting-rod, H, from a crank-shaft, H which is itself supported in suitable bearings, 0, in the frame of the machine. On the ram H is an upward projection, a, in which is secured by a set-screw, e, a plunger, 6, made slightly smaller than the interior of the knife E, and arranged in line axially therewith. The ram H advances periodssassz E,and thereby causes the knife to cut the blank into circular form. The blanks are by the plunger e pushed ahead and into the knife one by one, and during the operation of the machine the knife is filled with blanks S, as shown in Fig. 5. The spring e (shown in Fig. 5) produces a dragging action upon the top of the blank S as it passes beneath it, and holds the upper edge of the blank back, so that the blank will usually become detached from the socketpiece 6 at its lower edge, as is illustrated by dotted lines in Fig. 5, and will fall edgewise and in proper position into and through the chute F. The blank will, by the spring or retainer e, be prevented from tilting over, and thus entering the larger or upper end of the chute F flatwise, which would clog the chute.

In order to operate upon bung-blanks of different sizes, for producing difterent-sized bungs, it is necessary that the side pieces, D, of the chute for square blanks, should be moved more or less toward and from each other, as the case may be, and it is necessary that the table or rest G should be correspondingly raised or lowered, so that the table or rest will always hold the bnng'blank, whatever be its size, with its center opposite the axis of the knife E. To provide for this adjustment of the table or rest G, I connect the blocks or slides D, which may be considered as the lower ends of the side pieces, D, of the chute, by an angular hanger, G, which in its lower angle supports the table or rest G. The two arms of this angular hanger fit groovesf in the blocks D, and are secured therein by boltsf, passing through slotsf" in the hanger. The hanger is thereby given a sliding bearing in the blocks D, and as said blocks and the side pieces, D, of which they form part, are adjusted toward or from each other the hanger and the table or rest G, which it supports, will be correspondingly raised or lowered.

The two portions or members of the hanger G may be considered as forming arms or bearers, which are inclined at opposite angles from the side pieces, D D, and which supportthe table or rest G.

In order to enable the table G to be properlyadj usted when the machine is first erected, I have represented it as supported and held by a clamping-screw, f, passing through the hanger and entering the table, and by-a setscrew, f, as shown in Fig. 9. By setting up the set-screw f the table or rest will then be moved upward along the opposite side of the hanger to the required position, and then there held by tightening the clamping-screw f". The table or rest G having been thus properly adjusted relatively to the other parts of the machine, will be automatically raised and lowered with the hanger whenever the side pieces, D, are adjusted toward and from each other. As best shown in Fig. 1, the table or rest G has at one side a flange, f, which laps downward on the face of the hanger G. As the circular blank drops down the chute F for round blanks, it falls into a blank receiver or basket, 5 which is a semicircular projection upon the end of the collar 9, adapted to slide upon the exterior of the male compressing-die I, and in the end of the ram H is fixed a cupshaped or female cornprcssingdie, 1. (Best shown in Figs. 1, 5, and 7.) The male compressing-die I is, as here represented, held in place by a bolt, 1' inserted through the framing O of the machine and screwed into the die, and, as shown in Fig. 1, this bolt is hollow,and has arranged within it a sliding rod, g which is surrounded by a sprin g, tending to constantly press it for ward or toward the female compressing-die l. The blank receiveror basket 9 has in its lower side an upwardly projeating pin or screw, 9, which works in the slot 9 in the male compressing-die I, and against which the end or head of the spring actuated rod 9' bears. By means of this spring-actuated rod or head the blank receiver or basket is automatically projected intov the position'shown in Figs. 1 and 5, so as to catch the bung-blank S, which drops through the chute F, and when the female compressingdie l advances the receiver or basket 9 y will, by the resilience of the spring g, yield to the pressure of the female compressingdie, and be pushed back ward on the male die out of the way, leaving the blank caught between the male and female compressing-dies.

In order to prevent the blank when it falls onto the receiver or basket gg from tilting forward, I have shown thelatter as provided on opposite sides with springretainers g, which are arranged in grooves 57 within the receiver or basket, and which are slightly hooked or turned inward at their outer ends, as shown in Fig. 8. As the blank falls, it drops behind the hooked ends of the spring-retainers g, and is thereby prevented from tilting forward, and when the yielding receiver or basket 99' is pushed back by the female compressing-die the spring-retainers y will yield outward, so as to enable them to readily pass the blank.

Arranged axially within the female compressing-die is a stationary rod 'or ejector, l, which, as here shown, is fixed by a pin or screw, 9, to a part of the framing C. The ram H is slotted at g on its under side to pass the pin g and is bored out to receive the ejector I within it. As the female compressing die I is advanced by the movement of the mm H, it leaves the ejector l behind it, and by the action of the dies I l the circular bungblank is forced into the taper cup'shaped compressing-die I, and is thereby compressed and given the desired taper form. As the female co mpressing-die I recedes,it has the completed bung within it, and before it completes its return movement the bung is brought against the end ot'the stationary ejector l and pushed out of the cup shaped compressingdie 1, falling into a box or basket placed to receive it.

In the ordinary operation of the machine it after described.

is intended that but one blank S at a time shall leave the inner end of the knife E and fall through the chute F into the blank receiver or basket g, and but one blank will fall in case the blanks are of uniform thickness. It will be readily seen, however, that if a blank which is somewhat thinner than the others is entered into the knife E the blank which is at the inner or delivery end of the throat or socket Q will not fall, and the operation of the machine will continue, except that at the next forward movement of the ram H the compressing-die I will not receive any blank, and will return empty. If it further happens that a thick blank be forced into the knife E at the next forward movement of the ram H, two bungblanks will be delivered, one after the other, into the chute, and the upper one will rest upon the lower one, which latter is supported by the blank receiver or basket 9. If this second or upper blank should be thus brought unduly within the range of the female compressing-die I, the die would force the second blank also forward, and would push forward or swing outward the movable front F of the chute F, which is more fully herein- In order to prevent this, I form upon the top of the female compressingdie an inclined or wedge-like surface, 9 which is best shown in Figs. 5 and 7. W'hen thus constructed, the female compressing-die will, if a second or upper blank be in its way, pass under said blank, and the inclined surface 9 will lift the upper blank and enable the die to act with compressing or crushing force only on the single blank which is within the basket or receiver.

Near the lower ends of the side pieces, D, which constitute the chute for square blanks, the flanges d at the front thereof areremoved, and the plate D, which constitutes the front of such chute, is secured by a set-screw, h, to an arm, D which is mounted upon a rockshaft, h. Upon the same rock-shaft h, but capable of swinging independently of the arm D, is a lever, D and that portion of the arm D which projects above the rock-shaft has a lateral projection or ear, h, which is adapted to bear against a set-screw, it, carried by the lever D, and capable of adjustment therein. The front plate, F, of the chute F is also mounted upon a rock-shaft, F, so that it may swing outward, the rockshaft being supported in suitable bearings, c, projecting from the framing C of the machine, as shown best in Figs. 2 and 4. The rock-shaft F has at the end a downwardly-projecting arm, h which,

as shown in Figs. 1 and 2, is connected by a chain or other connection, k with the lower end of the lever D.

From the above description it will be clearly understood that in case either of the chutes becomes clogged in any way, so as to oppose an obstruction in the way of the cutting plunger or presser e or the female compressing-die I, such obstruction will cause the 1 front plate D or F of the chute to swing outward. Such outward movement of the plate D of the chuteD for square blanks will cause the upper end of the arm D to act upon and move the lever D, and such outward movement of the front plate, F, of the chute for round blanks will exert a pull through the chain It, and will move the lever D in the same direction. The connection h between the arm h and the lever D should be of such nature as to act by tensile strain only, and hence while such connection will transmit the swinging movement of the front plate, F, to the lever D*'it will not transmit any movement from said lever to the front plate, F, when the lever is moved by the swinging outward of the front plate, D, of the chute for square blanks.

Upon the crank-shaft H is a driving-pulley, H, which, through a clutch of suitable construction,transmits motion to the shaft. There are many different forms of clutch which comprise projecting arms or toes i, as shown in Fig. 2, and a spool or sleeve, i, adapted to slide on the shaft and having a taper end, which, entering between the arms or toes z, forces them apart and makes the clutch operative to turn the shaft.

In carrying out my invention I employ a tripping mechanism, whereby the clutch is held in operative position on the shaft, and which, when operated, will release the clutch from the shaft; and I employ connections through which the movement of the lever D serves to throw off the tripping mechanism and release the clutch.

In the machine which I have chosen to illustrate my invention the clutch spool or sleeve 2" is controlled by a yoked lever, J, embracing the spool or sleeve, and fulcrumed at its lower end, j, as shown in Fig. 3. WVith the upper end of the lever J is connected a rod, J, which slides through a sleeve, J, as shown in Figs. 1 and 2.

J designates a shifting or starting handle, which is fulcrumed at j, and has an upwardlyprojecting forked arm,j, embracing the sleeve J, and connected therewith. In the sleeve J, which is best shown in Figs. 11 and 12, is fulcrumed at 9' a locking and tripping lever, J, which, by means of a coilspring, j, applied to the fulcrum-pin of the lever, is held within a notch, f, in the sleeve, and caused to project partly into the bore of the sleeve, as shown best in Fig. 11. This locking and tripping lever J, as it projects into the bore of the sleeve, enters a notch, j", in the clutch-operating rod, J, and thereby holds the sleeve and rod against longitudinal movement, one relatively to the other. If the locking-lever J be engaged with the notch in the rod J, the starting-handle will when moved downward move the sleeve J and rod J in a direction to force the spool or sleeve 0 between the clutch arms or toes 27, and will thereby lock the driving-pulley H to the shaft. The framing O of the machine may itself form a stop to the lever J as the latter is moved downward.v

IIO

I have in the drawings shown the lever J the sleeve J and the remaining parts of the clutch-operating mechanism in their middle or intermediate position, and by raising the lever J upward the clutch will be naturally thrown off, while by moving it downward the clutch will be made fully operative.

Upon the rod J ,I have represented a spring, j, acting between a shoulder on the rod .and the end of the sleeve J and it will be readily understoodthat if the locking and tripping lever J be pushed outward, so as to free it from the notch J in the rod J, the springj will throw the rod and the attached spool or sleeve iin a direction to free the driving-pulley from the shaft, and the machine will be stopped.

The above-described lever D is connected at its upper end with the rod D, fitted to a guide, 0, and carrying atits end a knockingplate, D, having a considerable horizontal projection, as shown best in Fig. 2. \Vhatever be the position of the sleeve J upon the rod J,the plate D will always have some por-' tion of it opposite the lever J, and if at L any time the front plates D or F of the two chutes are swung outward by any obstruction they will act, through thelever D, rod D", and plate D,to throw the locking and tripping lever J out of engagement with the notch in the rod J, and the rod, being thereby released from the sleeve J will throw off the clutch and stop the machine. 7

In starting the machine it is only necessary, by means of the handle or lever J to move the sleeve J until the locking and tripping lever J engages the notch in the rod J, and the handle or lever J may .then be operated to throw on the clutch and start the machine.
