NEEDLE-GROOVING MACHINE.

SPECIFICATION forming part of Letters Patent: No. 378,489, dated February 28, 1888.

Application tiled November 2, 1887. Serial No. 254,035. (No model.)

To all whom it may concern:

Be it known that I, Pl-IILO M. BEERS, a citizen ofthe United States, residing at Bridgeport, inthe county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Needle-Grooving Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use 1 the same.

My invention has for its object to simplify and improve the construction of this class of machines, the special object being to facilitate the adjustment for different sizes and styles of needles and to greatly increase the capacity of the machine. With these ends in view I have devised a novel feeding mechanism, a novel device for stopping the machine should the supply of needles become exhausted, or should the jaws fail for any reason to grasp-a needle, and have so organized the machine that but one mechanism requires adjustment in changing from one class of needles to another.

I will now proceed to describe my novel machine, referring by numbers to the accompanying drawings, forming part of this specification, in which- 4 Figure 1 is a side elevation of the entire machine, a needle havingj ust been placed in the dies; Fig. 2, a partial side elevation illustrating the feeding` mechanism in the retracted position, the needle j ust acted upon having been dropped; Fig. 3, an end elevation of the feeding mechanism, the position of the parts corresponding with Fig. l; Fig. 4 a plan view of the feeding mechanism, the position of the parts corresponding with Fig. 1; Fig. 5, asimilar plan View, the position of the parts corresponding with Fig. 2, except that the completed needle has not been dropped; Fig. G, a detail view illustrating the construction of the automatic stop mechanism, the parts being in view, a needle having been grasped by the dies; Fig. 8, a similar view illustrating the action of the stop mechanism when no needle has passed into the dies; Fig. 9, a detail sectional View on the line x x in Fig. 1, illustrating the mechanism which releases the clutch-dog that connects the shaft for actuating the feeding mechanism with the driven shaft; Fig. 10, a detail sectional view on the line y y in Fig. 1, illustrating the mechanism for conne-cting the shafts; Fig. 11, a detail sectional View illustrating a portion of the feeding mechanism; Fig. 12, a detail sectional view illustrating the construction of the gripping-jaws; Figs, 13 and 14, detail views illustrating the preferred construction of the lever for returning the carriage; Fig. 15, a cross-section of the hopper, table, &c., showing the cross-slides iii-position to receive a needle; Fig. 16, a similar view showing the cross-slides at their forward position; Fig. 17, a detail section on the line z ein Fig. 7, showing the mechanism for closing the dies; and Fig. 18 is a detail rear elevation of the diecarriage.

Similar numbers denote the same parts in all the figures.

1 denotes a shaft driven in any suitable manner-for example, a worm, 2, engaging a wormwheel, 3, as shown in Fig. 1.

4 is an independent shaft placed in line with shaft 1, to which it is intermittently connected by a clutch, 5. These shafts are journaled in suitable bearings under the bed ofthe machine, which I have designated by 6.

7 is a cylinder or barrel on shaft et, which is provided with cam projections, indicated, respectively, by 8, 9, 10, and 11.

12 is a table at the front end of the machine, the left, as seen in Fig. 1, upon which is placed the hopper and the feeding and extracting mechanism. The dies by which each needle is held during the operation of grooving, the movements of the die-carriage, and the cutters by whichy the operation is performed are the same as in my former patents, No. 217,921, dated July 29,1879, and No. 258, 695, dated May 30, 1882, and will therefore not be described in detail. One of the cutters appears in Fig. 1, and is designated by 13. The upper and lower dies are designated, respectively, by 111 and 15, and the sliding die-carriage by 16.

17 denotes the hopper which is attached to table 12, and is provided with slots 18 in opposite sides thereof.

19 denotes a carriage sliding in ways inthe table.

The hopper is made widest at the end toward the front of the machine and the needles lOO are placed therein with the shanks at that end of the hopper. The hopper narrows down toward the bottom and leads into curved passage 20, just wide enough to receive a single needle. The needles are agitated in the hopper and caused to feed down freely by means of a curved spring, 21, secured to the inner end of a lever, 22. This lever is pivoted in a yoke, 23, swiveled in a bracket, 2i, upon the table.

25 is a block secured to the sliding carriage and having an incline, 26, and an undercut circular groove, 27. A ball depending from the outerend of lover 22 engages this groove, so that as the carriage moves backward and forward, upward, downward, and lateral motions are imparted to spring 21, causing it .to enter the groove at one side of the hopper and lift the needles therein at each reciprocation of the carriage, substantially as in my former patent, No. 339,361, dated April 6, 1886.

28 and 29 denote, respectively, upper and lower cross-slides which are caused to reci procate under the hopper. The forward end of the lower cross-slide extends outward beyond the upper cross-slide, and is provided with aprojection or thickened portion, 29, the upper surface of which is level with the surface of the upper slide. The rear edge of this projection and the forward edge of the u pper cross-slide are both undercut, as clearly shown in Figs. 15 and 16, an undercut groove or recess being thus formed between said slides, the lower slide forming the bottom of the recess, which is adapted to receive one needle at a time from passage 2() and carry it out from the hopper, ready to be moved forward to be acted upon by the grooviug mechanism, as will presently be fully explained.

The reciprocatory movements of the crossslides may be imparted in any suitable manner, preferably, as shown in the drawings, by a lever, 30, pivoted to the table. One end of this lever is provided witha roller, 31,adapted to engage a switch-cam, 32, and the other end is connected to the cross-slides, as shown in Figs. 15 and 16.

30 denotes the pivot-pin which connects lever 30 with the cross-slides. This pin is fixed in the upper cross-slide and extends downward and engages a slot, 29, in the lower crossslide. The switch-cam is pivoted to the sliding carriage, and is shown in its normal position in Fig. 5, in which position it is held by a spring, 33. `As the carriage moves forward from the position shown in Fig. 5, roller 31 engages the outer wall of the switch-cam, first presses itinward against block 25, the springl yielding, and then travels along the outer wall of the switch-cam, the effect of which movement is to force the cross-slides inward and carry the needle-groove out from under the hopper. As soon as roller 31 has reached the rear end of the switch-cam, spring 34, one end of which bears against a projection on lever 30, acts to force the rear end of said lever inward, as shown in Fig. 4, and returns the crossslides to their former positionmthat is, un-

der the hopperready to receive another needle. During the return-movement roller 31 travels along the inner wall of the switch-cam.

In practice I preferably make lever 30 in two parts, as indicated in Figs. 4 and 5, both parts being journaled on the same pivot and provided with projections between which a strong spring, 35, is placed. This spring is strong enough, so that in ordinary use it yields but slightly, so that with each reciprocation of the carriage a corresponding reciprocation ofthe cross-slides takes place. Should the cross-slides become wedged, however, as by an imperfect needle or from any cause whatever, spring 35 will yield and prevent any breakage of the parts when the forward movement of the carriage takes place. This spring is adj usted by a set-screw,35. It will ofcourse be understood that while the parts of the feeding mechanism are moving from the position shown in Fig. 4 to that in Fig. 5 the crossslides remain stationary. The instant the cross-slides have reached the position shown in Fig. -1 vthe needle-groove will be directly below passage 20, so that a single needle will drop from the passage down into the groove. The operation of the cross-slides will be clearly understood from .Figs.15 and 16. WVhen the return movement takes place, the upper slide of course moves first, which separates the undercut edges of the two slides, opening the needle-groove slightly. As soon as pin 30a engages the outer end of slot 29b in the lower cross-slide, the latter begins to move backward also, which movement continues until the needle-groove is under the hopper, when a needle drops into the groove, as clearly shown in Fig. 15. Vhen the parts have reached the position shown in Figs. 5 and 15, they are ready for the next forward movement of the cross-slides. At the proper time the upper slide moves first and the forward edge thereof is closed against the needleinthe rcg,

IIO

groove, the needle being thus held firmly between the undercut edges of the two slides. As soon as pin 300 engages the inner end of slot 29", the lower cross-slide begins to move forward also, and the parts move to the position shown in Figs. 11 and 16, the needlegroove having passed outfrom under the hopper, carrying the needle with it, as will presentlybe more fully explained. In the drawings Ihave shown the hopper as held in place by screws 17a, which pass through slots in the cross-slides.

35 denotes a frictionspriug secured tothe table and bearing against. block 25, to insure steady movement of the carriage. The extracting mechanism consists of two grippingjaws, 36 and 37. The rear end of the shank of jaw 36 is pivoted to a block, 38, upon the carriage, this jaw being stationary relatively to the other jaw. Jaw 37 is pivoted about midway its length between ears 39 on the shank of jaw 36, and swings toward or from said jaw, as will be more fully explained.

40 is a set-screw which passes through the IZO shank ofjaw 37 and engages the shank ofjaw 36, acting as a stop to limit the movement of the jaws in opening.

41 is a bracket secured to jaw 36, and 42 a plate adjustably secured to this bracket,whieh is provided with a finger, 43, curved in suitable form to engage the needle in the groove between the cross-slides. (See Fig. 11.) This finger acts to force the needle forward between the dies ready to be operated upon by the grooving-cutters when the forward movement of carriage 19 takes place.

As already stated, the movements of the die` carriage and the grooving-cutters, not being part of my present invention, will not be described in detail.

The forward and backward movements of carriage 19 and the cross-slides, the carrying forward of the needle into the dies, and the movements of the gripping-jaws in taking the needle from the dies and dropping it are all accomplished through the instrumentality of a lever, 44, pivoted in the present instance in the bed of the machine. The upper end of this lever passes through a slot, 45, in table 12, and a corresponding slot through the can riage, and rests in a recess, 46, in adjustable plate 47, secured to slide 48, which is adapted to reciprocatelongitudinallyin undercut ways in carriage 19, plate 47 projecting over the slots, as clearly shown in Figs. 4 and 5. Turning now to Fig. 12, which is a reverse View of -jaw 8G, it will be seen that said jaw is connected to the forward end of slide 48 by a link, 49, Figs. 4 and 12. Both show the position of the parts at the instant the grooving action of the cutters has ceased and the needle is ready to be extracted from the dies. As lever 44 begins to move backward, carrying slide 4S with it, the first action is to raise the jaws by means of the link. This movement places the jaws on opposite sides of the needle. An instant later, as the lever continues to move backward, it engages inclines 50 at the rear ends of the inner sides of the shanks of the jaws, forcing the shanks outward and causing` the jaws to grip the needle firmly. The continued backward movement of the lever ear ries the jaws, the carriage, and all of the parts carried thereby back to the position shown in Fig. 5. The instant the forward movement of the lever begins it leaves inclines 50, thus allowing the Shanks to close together and the jaws to open, which releases the needle and allows it to drop out into a suitable receptacle below. As already stated, shaft l is continuously in rotation, but the operations ofthe grooving mechanism and of the extracting and feeding mechanism are alternate-that is to say, suppose the grooving of the needle to have been completed, the grooving mechanism ceases to act instantly and the movement of the other mechanisms begins, the finished needle being removed from the dies and a new one inserted, ready to be clamped in position and operated upon by the cutters. The instant the forward movement of carriage 19,

carrying the feeding and extracting mechanism, is completed, shaft 4, carrying the cams by which the parts are operated,is disconnected from shaft l through the automatic action of clutch 5, and the grooving mechanism is again placed in operation through the automatic action of another clutch, which I have designated by 5l. (Seen at the right in Fig. 1.) `When the operation of grooving a needle is completed, the forward movement of diccarriage 16 is stopped automatically through the action of mechanism fully described in my former patent, No. 217,921.

In order to make clear the operation of my present invention, I shall refer briefly to certain parts fully illustrated and described in my said former patent.

52 is a shaft having at its inner end a beveled gear,which, by means of gear-connections and cams, (not shown in this case,) imparts the necessary forward and backward movements to the cutters. Clutch 51 connects this shaft with a gearwheel, 53, which is continuously in rotation.

54 is a cam on shaft 52, and 55 an L-shaped arm upon a lever, 56. The inner end of this lever is pivot-ed to a fixed point, and at er about the center' thereof it is pivoted to a vertitically-movable block, 57, carried by rod 58, and pressed downward-that is, to its normal position-by a spring, 59.

G0 (see Fig. 3) is a lever the outer end ofV which engages block 57 and the inner endengages the feeding mechanism (not shown) for die-carriage 16. Then the die-carriage is earried inward-that is, toward the right-the operation of which will presently be fully, eX- plained, plate Gl at the rca-r end thereofengages clutch 51 and connects shaft 52 with the hub of gear-wheel 53.

It should be understood that the cutters are continuously in rotation, but are only` moved inward to their operative posi-tion by the action 0f shaft 52.

The operation of grooving the needle` is completed during a single rotation of shaft 52. As soon as the grooving operation is completed, arm 55 drops into a notch (not shown) in cam 54, causing block 57 to drop fromthe position shown, and causing lever (i0 to disconnect the feeding mechanism (not shown) which actuates the dic'carriage. An instant later cam 62 on the hub of gear-wheel 53 acts to disconnect shaft 52. These parts all operate as in my said former machine. In my present machine I extend rod 58 downward, or providean additional rod, 63, as shown in the drawings, in line with said rod, and support it in a sleeve, 64, upon the bedof the machine. This rod rests against the end of a lever, 65, and acts, when pressed down, to tilt said leverwhich lifts a springlatch, 66, and releases thespring` actuated dog 67 of clutch 5, thereby connecting the independent shaft 4 with shaft 1. This imparts rotation to cylinder 7, having the cam projections 8, 9, l0, and 11, which actuate the feeding and extracting mechanism,

TOO

the stop device, which I shall presently describe, and the lever, which causes the return movement of die-carriage 16. In Fig. 1 the position of the parts is shown at the instant a needle is about to be acted upon by thegrooving-cutters, and in Fig. 2 the position of the parts at the instant a finished needle has been dropped byA the clamping-jaws, carriage 19 having j ust commenced the forward movement. The forward and backward movements of this carriage, and incidental to said movements all the movements of the feeding and eX- tract-ing mechanism,are caused by the engagement of roller 68 at the lower end of lever 44 with cam projections 8 and 9 upon the surface of cylinder 7. Turning now to Fig. 1, as soon as the needle has been carried forward between the dics,and before it has been clamped there,the operation of which will presently be explained, dog 67 of clutch 5 is engaged by a stationary cam, 69, carried ordinarily by the shaft-bracket, and retracted, thereby disconnecting the independent shaft from shaft l. rIhe cams upon cylinder 7 andthe parts act-uated thereby will consequently remain in the position shown in Fig. 1. As soon as lever is tilted at the completion of the grooving operation, in the manner already explained, dog 67 is released again, thereby connecting shafts 4 and l, and imparting rotation again to cylinder 7, the movement of said cylinder being overfrom back to front, as indicated by the arrow in Fig. 3. As the rotation of the cylinder proceeds, the outer end of the inner wall of cam projection 8 first comes in contact with roller 68, and moves lever44 from the position shown in Fig. l to the position shown in Fig.

2. As said roller travels along this cam-wall,

the lirst action of lever 44 is to move slide 48 backward, which, by means of lilik 49, lifts the ciamping-jaws on opposite sides of the needle. As the backward movement of the lever continues, it engages inclines 50 at the rear ends of the jaw-Shanks, causing thejaws to grip the needle firmly. The continued movement of the lever moves the carriage to the position shown in Fig. 2. At the instant the backward movement ofthe carriage is completed roller 68 will have reached the end of the inner wall of projection 8, and will be en gaged by the outer wall of projection 9. (See Figs. 1 and 2.) As the roller travels along this wall,1ever 44 is caused to swing backward again tothe position shown in Fig. 1. The rst action ol' this lever in the return movement is to release the jaws so that the needle drops out. The lever then, by engagement with the recess in plate 47, moves slide 48 forward, which lowers the jaws again, in which position they are carried forward. By this time plate 47 will have engaged a plate, 70, on

the carriage, so that the continued movementof the lever forces the carriage forward through the engagement of the plates. Finger 43 now passes into groove 29 in the cross-slide and forces the needle forward into the dies. forward movement of the needle will be com- The' pleted at the instant roller 68 has reached the end of the outer wall of cam projection 9 on the cylinder, the parts being now in the position shown in Fig. 1, in which position they remain unt-il the grooving of the needle is completed, as already stated.

It will of course be understood by those familiar with the art that in this class of machines the operation of grooving is performed while the die-carriage, denoted in this instance by 16, is moving toward the left-that is, toward the table carrying the feeding and extracting mechanism. When the parts have reached the position shown in Fig. 1, and the needle has passed into the dies, the first operation is to close the dies upon the needle, locking it in place, as will presently be explained,

and the second to move the diecarriage forward-that is, toward the right suflicient distance,so that the groovingcutters, when moved forward into operative position, will begin to act at the desired portion ofthe needle. This return movement,77 as I term it, of the diecarriage is effected by means of a lever, 7l, pivoted to the bed of the machine. The upper end of this lever is provided with aset-screw, forming an adjustable point of contact. with the die-carriage, and thelower end is provided with a roller, 72, which is engaged by cam projection 11 on the cylinder, which acts to swing the upper end of the lever inward and move the die-carriage to the desired position. As has already been explained, when this carriage has reached the extremeofits movement toward the right, plate 6l, at the rear end thereof, actuates clutch 5l and again moves the grooving-cutters into operative position. In order to insure, however, that the grooving mechanism shall not act unless a needle has been placed in the dies, I have provided a stop device, which prevents the return of the die carriage should the needles have become exhausted, or should the gripping-jaws for any reason fail to operate perfectly. I thus insure that the grooving-cutters shall under no circumstances come in contact with the dies.

73 denotes a rock-shaft journaled in suitable bearings on the die-carriage, which serves the double purpose of actuating mechanism for closing the dies upon the needle and unclosing them again, and also mechanism for controlling the stop device. The mechanism for closing and unclosing the dies is clearly illustrated in Figs. 17 and 18.

14:L denotes va lever fulcrumed in a suitable bracket upon the die-carriage. rlhe forward end of this lever is pivoted to the upper die, as is clearly shown.

16 denotes a lever pivoted to a suitable stump at the outer edge of the die-carriage. This lever extends inward, and its inner end engages a cam, 73, at the rear end of rockshaft 73. 'lhe movement ofthe rock-shaft and cam being oscillatory, the action is of course to raise and lower lever 16au at each oscilla-l tion. At the rear end of lever 14a is a setscrew, 14", the end of which bears against le IOO IIO

ver 16, so that the upward movement of lever 16 tilts the rear end of lever 14, causing the forward end to clamp the upper die down firmly upon the needle, the backward movement of cam 73L of course acting to relieve the pressure of said die upon the needle. In practice the rear end of lever 14 is made heavy enough to drop by gravity and lift the die the instant lever 16L is allowed to drop by the backward movement of cam 73a.

16b denotes a set-screw in lever 16, the point of which engages the die-carriage. By means of these two set-screws I am enabled to adjust the upper die so as to clamp the different sizes and styles of needles.

16c denotes a stop, in practice made adjustable, which limits the forward movement of the needlethat is, it stops the needle at the exact place necessary in order to cut the grooves accurately. The stop device is clearly illustrated in Figs. 6, 7, and 8, and consists, essentially, of a plate, 74, pivoted to the forward end of the diecarriage. A curved iinger, 75, projects upward from this plate. This finger is so shaped that in use its end rests against the needle, as shown in Fig. 7, the needle being represented as held between the dies.

76 denotes a spring on the under side of the plate, which bears against a pin or suitable projection. The action ofthis spring is to hold the point of the finger against the needle, asin Fig. 7; or, should it happen from any cause that no needle is received bythe dies, the spring will throw the linger over to the position shown in Fig. 8, dropping the plate down, so as to leave opening 77 in the die-carriage uncovered. This opening` is made amply large to receive the upper end of lever 71.

7S is a cam on shaft 73, which, as soon as the dies are unclosed by cam 73 and levers 14n and 16, engages the outer end of plate 74 and moves said plate and the finger from the position shown in Fig. 7 to that shown in Fig. 6, and holds it there while the extracting and feeding mechanism are operatingthat is, until the new needlehas been placed between the dies. As soon as the new needle has been placed in the dies, the cam 73 acts to close the dies and lock them upon the needle. As soon as the locking of the dies has been cifected, cam 78 moves upward again to the position shown in Figs. 7 and 8, releasing plate 74. lf a needle has been properlygrasped by the dies, the end of the finger now rests against the needle, as clearly shown in Fig. 7. Should it happen, however, that a needle has not been received bythe dies, the finger swings by, and the plate drops down to the position shown in Fig. 8, leaving opening 77 in the diecarriage uncovered. After the movements just described the next movement is the movement of lever 71 to return the die-carriage. lf the needlehas been received by the dies, plate 74 must be in the position shown in Fig. 7, and is engaged by the upper end of said lever, andthe carriage moved backward.

n the absence of a needle from the dies, however, the downward movement of the plate, as in Fig. 8, uncovers the opening so that the upper end of the lever passes into it, moving by the plate, but not coming in contact with the carriage at all, so that the latter is not moved, and the grooving-cutters are consequently not thrown into operative position. In practice I preferably make lever 71 in two parts, substantiall y as shown in Figs. 13 and 14, both of said parts being journaled on the same pivot, a set-screw being provided to adjust their position relatively to each other, and a strong spring, 79, also adjusted by a set-screw placed between the parts. This spring is of course strong enough to carry the die-carriage backward in the ordinary working of the machine; but should it happen from any cause, however, that the die-carriage should become sea spring 79 would yield, and thus avoid the danger of breakage of any portion of the machine. Rock-shaft 73 is actuated by means of a bell-crank lever, 80, pivoted under the bed of the machine, and having upon one arm a roller, 81, which is adapted to engage the left wall of projection l0 on the cylinder and the right wallof projection 9. The other arm of the bell-crank lever is connected, by means of a link, 82With a rod, 83, which reciprocates in a suitable sleeve secured to the bed of the machine. At the upper end of this rod is a yoke, 84, which is engaged by the rod 86 of crank 85 on rock-shaft 73. The crank-rod is of course made sufficiently long to allow for the reciprocation of the diecarriage,as elearly shown in Figs. 1 and 2. In Fig. 6 the position of the parts corresponds with Figs. 1 and 3. As roller 81 rides along the wall of cam projection l0, the upper arm of the bell-crank lever is swung downward. This moves cam 78 from the position shown in Fig. 6 to that shown in Figs. 7 and 8, and permits finger 75 to rest against the needle or else to swing past,

IOO

and the plate to drop down outof the way,un-

covering opening 77 in the die carriage. After roller 81 has reached the end of the wall of cani-projection 10, it passes off onto theinner--that is,the right-wallof cam projection 9. The position of parts shown in either Figs. 7 or 8 is that at which the rotation of cylinder 7 ceases, as has already been eX- plained. As soon asthe forward movement of the cylinder commences again,roller 81 travels in the opposite direction down the inner or right wall of cam projection 9, the action of which is to move cam 78 back to the position shown in Fig. 6, carrying the point of finger 7 5 away from the needle, so that there shall be no obstruction to the ready withdrawal of the needle by the gripping-jaws and the placing of thc new needle between the dies by the feeding mechanism. Vhcn the parts have reached the position shown in Fig. 6, roller 81 will have passed off from the wall of cam projection 9, and the parts will remain in the position shown until said roller is again engaged by the left wall of projection 10, as shown in IZO ISO

Fig. 1,the action of which is to cause thelocking of the dies again, and also at the proper time to throw the end of finger 7 5 against the needle or else to prevent the return movement of the die-carriage, as has been fully explained.

As the operation of each mechanism and its connection with the other mechanisms has been already fully explained in this specification, further description of the operation of the machine would be superfluous.

Having thus described my invention, I claim 1. The combination, with a hopper for needles and an agitatingspring, of upper and lower cross-slides adapted to pass under the hopper and having formed between them a groove of sufficient size to receive a single needle. v

3. The combination, with the hopper, of an upper cross-slide undercut at its forward edge, and alower cross-slide having at its forward end a projection, 29, undercut at its rear edge, a needle-groove being formed between said edges, having for its 4bottom the lower cross-slide.

4. The combination, with the hopper an the reciprocating cross-slides having a groove adapted to receive a needle from the hopper, of a curved finger adapted to engage the groove and move longitudinallyT therein to carry the needle forward.

5. The combi'natiomwith the table and hopper, of carriage 19, the crossslides having a groove adapted to receive a needle, and finger 43.

6. The combination,with the table and hopper, of carriage 19, carrying a switch-eam,and a lever, 30, pivoted to the table, one end of said lever being connected to the crossslides and the other adapted to engage the switch-cam.
