ROLLIN H. WHITE, OF CLEVELAND, OHIO.
MACHINE FOR MAKING BALLS.
SPECIFICATION forming part of Letters Patent No. 635,215, dated October 1'7, 1899.
Application filed August 81 1898.
To all whom it may concern:
Be it known that I, RoLLIN H. WHITE, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented a certain new and useful Improvement in Machines for Making Balls, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.
The invention relates to a machine especially designed for making steel balls by automatically cutting from steel wire blanks of the proper size and pressing said blanks between suitable dies into spherical form.
The invention consists in the construction and combination of parts shown and described, and definitely pointed out in the claims.
In the drawings, Figure l is a front elevation of a machine embodying the invention. Fig. 2 is a plan view of the same with the plunger and parts carried thereby not shown. Fig. 3 is a sectional front elevation on line 3 3 of Fig. 2. Fig. 4 is a sectional side elevation on line 4 4 of Fig. 2. Fig. 5 is a sectional plan view in the plane indicated by line 5 5, of Fig. 4, showing the mechanism for cutting off the blanks and delivering the same to the dies.
The invention is adapted for any wellknown form of press having a vertically-reciprocating plunger. Therefore it is not thought necessary to show all of the plunger or any of the mechanism for operating it.
Referring to the parts by letters, A represents the vcrtically-reciprocating plunger of such a press.
B represents the bed-plate. The fixed die 0 is set into a socket in a block b, which is secured upon or formed as a part of this bedplate. The upper end of this die is preferably convexly arched, and in the middle of its upper end is a hemispherical recess 0.
D represents the movable die, which is secured in the lower end of the plunger. Its lower end is preferably convexly arched, and in the middle of this lower end is a hemispherical recess d.
A vertically-movable ejector-pin F lies and is movable in a hole I) in the bed-plate and in the lower die, and the upper end of this pin projects into the recess 0, being held in this Serial No. 688,038. (No model.)
position normally by a light spring f. The lower end of this pin projects below the bedplate and lies above one endof a rocking lever H, which is pivoted to the bed-plate at h. The other end of this lever liesjust below a vertically movable rod J, which projects through the bed-plate and is held in its raised position by a springj. The upper end of this rod (which may carry a friction-roller j) is engaged by a cam e on the constantly-driven shaft E. It might be here stated that this shaft carries a plurality of cams, by means of which various parts of the machine are operated in proper sequence. The cam e pushes therod J downward and the press-plunger begins to rise after a ball has been completed. This rocks the lever H, whereby the ejector F is pushed upward, positively assisting its spring, with the result of pushing the ball from the recess a. In the upper die is a similar ejector I, which is vertically movable in a hole a in the die and the plunger A. The lower end of this ejector projects into the recess d, in which position it is normally held by a light spring (1. A lever a is pivoted to the plunger A and passes through a slot (1 therein. This lever rests upon the upper end of the ejector I. Secured to the free end of this lever and hanging downward therefrom is a rod a, which passes through ahole in the bed-plate. When the plunger begins to rise, the spring d and the weight of the lever 64 and the attached rod or will generally force the ejector downward relatively to the plunger and die and push the ball out of the die. If, however, the ball is not pushed out then and in the manner stated, a head a on the lower end of the rod ct strikes the bed-plate at or just before the time the plunger reaches its highest point, andthis causes the lever to rock, so as to positively force the ejector downward and push the ball out of the recess d.
The blanks to be pressed into spherical form between the dies are cut automatically from a wire X, which is periodically fed along the proper distance. The blanks so out are carried by certain j aws,to be presently explained, to a position to be acted upon by the dies. The wire X passes through a horizontal hole in a hardened block 0, which is set in a block b which is secured upon or fastened to the bed-plate. A shearing-plate G is vertically movable upon the face of said block b -lI1 suitable guides 11 It is provided with a hole g, which when said shearing-plate is in its raised position is in line with the hole in the block 0, through which the wire passes. This hole 9 is preferably in a hardened plate 9, which may be screwed into the shearingplate, thereby becoming in effect a part of said plate. This plate G is held in its raised position by a spring 9 which surrounds a bar 9 which projects downward from the lower end of this shearing-plate and passes into a guiding-hole in the bed-plate. A strikerpin 9 screws into the upper end of this shearing-plate, and the head of this pin lies in the path of the plunger A, which plunger strikes it as it descends, thereby moving the shearing-plate downward in opposition to its spring and cutting off the wire in the hole g in said shearing-plate.
The wire is fed along and held immovable at the proper times by two pairs of jaws R R and T T. The jaws R R are the holdingjaws, which have no movement lengthwise of the wire. The lower jaw R is seated in a hole in the block 11 while the upper jaw is held in a hole in a lever 0*, which is pivoted at r to said block b and is moved in the closing direction by a cam c on the shaft E, which cam engages with the rear end of said jaw-lever r.
The jaws T T are the feeding-jaws. The lower jaw T is seated in a cross-head t, which is secured to the end of a longitudinally-movable rod S. This rod is mounted in suitable brackets b b and is moved backward by means of a spring S, which surrounds the rod and thrusts endwise against one of said brackets b and against a collar S secured upon said rod. The distance which it may be moved backward is regulated by a screw S which may be adjusted through the bracket b and serves as a stop by engaging with said collar S The rear end of the cross-head is bifurcated and the shaft E passes through holes in the two branches t t thereof. On the shaft and having a tongue-and-groove connection with it is a cam 6 which lies between the two branches 25 25*, whereby said cam moves with the cross-head lengthwise of the shaft E without any interruption of its operating relation with the jaw-lever t which it operates. The upper jaw T is set in the end of the jaw-lever 15 which lever is pivoted to the cross-head at 154. The rear end of this jaw-lever rests upon the cam 6 by which it is moved in the closing direction.
Secured to the shaft E is a cam 6 which engages with the cross-head (preferably with a friction -roller t, mounted thereon) and moves it to the left in opposition to the spring S The wire X passes between both pairs of jaws just explained. The cam 6 acting upon the jaw-lever t closes it upon the wire, and at the same time the cam 6 so moves that it no longer acts to close the jaw-lever r.
The cam c then moves the cross-head t to the left, whereby the wire in the grasp of the jaws T T is moved in the feeding direction. Then the cam c, acting upon the jaw-lever r, closes the jaws R R. The cam 6 moves so as to release the jaws T T, and the cam 6 moves to a position which permits the spring S to retract the cross-head and jaws T T. This completes one feeding movement of the wirefeeding mechanism. The plunger A then comes down, and by engaging with the strikerpin 9 secured to the shearing-plate, moves said shearing-plate downward, the result being that so much of the wire as has been forced into the hole in said shearing-plate will be cut off, and this cut-off blank will for the time being remain in said hole.
During the next wire-feeding operation this blank is pushed out and into the embrace of two jaws U U, by which it is carried to the dies. These two jaws are secured to the outer ends of two j aw-levers u it, which are pivoted on a rock-shaft XV. The jaws are closed by the action of a spring a against a pin to, which projects between them from an arm to, which is rigidly fastened to the end of said rock-shaft. By closing against this pin the jaws maintain the proper position relative to the rock-shaft, whereby the operation of the rock-shaft will carry the jaws from one operative position to the other. On the rear end of this rock-shaft, which is mounted in a suitable standard U, which rises from the bed plate, is a crank 10 carrying, preferably, a friction-roller 10 which enters a cam-groove c in the face of a disk c, which is secured to the shaft E. As the shaft revolves, said camgroove and crank operate the rock-shaft, so as to carry the jaws first into position where the recess between the jaws is in line with the wire X and then to a position where said recess is in the same vertical plane as the hemispherical recesses in the two dies. The jaws are in the first of these two position when the wire-feeding mechanism acts, and as the wire is pushed along it pushes the blank which is in the hole in the shearing-plate out into the recess between said jaws. The jaws are opened to permit the blank to enter between them by means of a wedge Y, which is horizontally moved through a bracket Z)" on the standard If, and this wedge is moved forward, so as to cause it to enter between the two jawlevers by a cam e on the face of the disk 6. This wedge is moved in the contrary direction by a spring y. This backward movement of the wedge, whereby the jaws are permitted to'close, takes place just before the jaws move from the described position to the position in line with the dies. As the plunger descends; a wedge-bar Z, which is secured to the plunger, is moved between the two rollerstuds 10 it on the jaw-levers, whereby the jaws are opened j ustas the upper die reaches a point where it engages with said blank; The further descent of the plunger presses the blank into spherical form in the recesses in the two dies. The plunger then moves upward and the lower ejector is moved upward by the mechanism heretofore described for.
the purpose, and the finished ball is pushed out of the recess 0 into the recess between the jaws, which jaws immediately close and are then moved to the other position in line with the wire X. During the next feeding move-.
ment, which pushes a blank into the embrace of these jaws, this blank pushes the ball out of the jaws (if it did not fall out.when the jaws were opened) and said ball falls into a funnel-shaped receiver K, from which it may be conducted through a pipe (indicated by dotted lines in Fig. 1) to any convenient point.
A guard-plate I3, which is secured to the block 19 lies in line with the wire X, whereby the balls as they are pushed out of the embrace of the jaws are prevented from flying to the left so far that they will not fall into this funnel-shaped receiver.
The machine described is adapted to be very readily and easilychanged so that wire of different sizes may be used. It is of course necessary to remove the dies and put in new dies having hemispherical recesses of the proper size. The position of the striker-pin on the shearing-plate will then be adjusted so that the downward movement of the shearing-plate will be sufficient to cut ofi the wire. A new block 0 having a hole of suitable size for the wire may be substituted for that which is in the machine, and the position-of the two jaws R and T may be regulated to adaptthem to properly grasp the different-sized wire by means of the screws which screw down through the jaw-levers and bear uponthe tops of the jaws.
