I INVENTOR v UNITED STATES PATENT OFFICE.
JAMES P. MAsoN, or PHILADELPHIA, PENNSYLVANIA, ASSIGNOR on one HALF TO THOMAS M. MOORE, or smart PLAoE.
NUT-MACHINE.
SPECIFICATION forming part of Letters Patent No. 256,845, dated April 25, 1882,
Application filed May 2,1881. (Model) To all whom it may concern:
Be it known that l, JAMEs P. MAsoN, of the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvementsin Nut-Machines, of
which improvements the following is a specification.
The object of my invention is to enable a series of nuts to be simultaneously cut and r0 punched from a continuous blank or bar without waste of metal beyond thatof the cylindrical punchings removed in the formation of the openings in which the screw-threads are to be formed.
To this end my in'iprovements consist in sundry novel devices and combinations of mechanism hereinafter. set forth, the same embracing a pair of shearing and punching dieboxes, each having a series of punches and abutments alternately located throughout its length, the punches of one die being located opposite the abutments of the other; mechanism whereby the dies are alternately pressed together upon the nut-blank and withdrawn therefrom; reciprocating grippers for holding the nut-blank in position to be acted upon by the dies; devices for relievingthepunches from the cut and punched nuts, and mechanism for discharging the cut and punched nuts into a 0 proper receptacle.
In the accompanying drawings, Figure l is a side view, partlyin section,ot' a nut-machine embodying my improvements; Fig. 2, a vertical longitudinal section through the same at 5 the line 1 1 of Fig. 3; Fig. 3, a horizontal section at the line 2 2 of Fig. 2; Fig. 4, a vertical transverse section at the line 3 3 of Fig. 2; Fig. 5, a similar section at the line 4 4 of Fig. 1; and Fig. 6, a side view, in elevation, of the 4o backing-plate.
To carry out my invention I provide a substantial metallic frame, A, which is formed in two sections, firmly connected by bolts 0, and is secured by bolts to a proper foundation. A
head or carrier, B, is mounted in each section of the frame A, each head serving to receive one of the multiple shearing and punching die holders or boxes, to be presently described,
and oneor both being susceptible of horizontal reciprocation between guides A upon theframe. In the instance illustrated two movable heads are employed, and such construction will be herein described; but, if preferred, one of the heads may be made stationary and the other movable, a longer traverse being of course re- 5 5 quired in the latter case.
Ahorizontaldriving-shaft, O, to which power is communicated from a prime mover, is sup ported in bearings 0 upon one side of the machine parallel to thelongitndinal central plane thereof, and carries two worms, 0 a, each of which meshes with a worm wheel, G, fixed upon a transverse shaft, 0 mounted in bearings in the frame A, and having eccentrics c secured upon it adjacent to each of its bear- 6;, ings. Each of the eccentrics c fits within a yoke, B, formed in a lateral prolongation of theheads B, and by the rotation of the shafts G reciprocating movement is imparted to the heads B toward and from the intermediate vertical central plane of the machine. A diebox, D, is fitted to each of the heads B, and a set of punching and shearing dies are secured therein by caps D, having downwardly-pro jeetingkeys d, so that the dies may be readily insertible and removable, and be firmly held when in position, each of said sets consisting of a series of punches, at, and abutments d arranged alternately in the die-boxes.
The metal of the punch-dies is recessed or dished out around the bases of the punches at, so as to give the proper form to the tops of the nuts, and the abutment-dics d are perforated byacentralopening, which graduallyincreases indiameter from the front to the back of the die, so as to admitot' the free and unobstructed discharge of the metal removed by the punch of the opposite die-box,eachof the abutments in one die-box being located in the same axial line as one of the punches in the opposite diebox.
'1 hcseveral dies of each series are held in position in theirrespective boxes by tongues, which enter corresponding grooves in the die-box auditscap,andbystoutmetallicbacking-plates 5 d perforated with openings correspondinginlocation and dimensions with those of the punching-dies and with the strippers presently to be described, the upper and lower sections and the backing-plates being clamped together by the caps D of the die-boxes. The cut and punched nuts are discharged from the punches by stationary strippers'E, which are plates of metal having T-heads, by which they are retained in position in bars 6, slotted vertically to admit the heads of the strippers. Each of the bars 0 is fitted in a recess in the frame A behind one of the headsB, and, with the strippers E held therein by a removable cap, 6, is inserted and removed with the die-box, to which its strippers are applied.
The strippers E are located one on each side of each of the punches d, passing through slots in the backing-pieces d and recesses in the punch-dies, and, inasmuch as the distances between these slots are governed by the diameters of the nuts to be formed, any change in the size of the dies for the purpose of making larger or smaller nuts mnstbe accompanied by a corresponding change in the backingpieces d and stripper-bars 0, separate pairs of backing-pieces, stripper-bars, and sets of strippers being provided for use with each of the several pairs of die-boxes employed.
The metal blank from which the nuts are to be formed is inserted through an opening in one side of the frame A, and is presented to the faces of the dies and clamped firmly in proper position relatively thereto during the shearing and punching operation by two grip persor clamping-bars, F F, which are located parallelto the faces of the dies and above and below the same, their vertical central plane coinciding with the plane of contact of the two sets of dies when pressed together by the V movement of the heads. The grippers F are supported in sliding frames F, fitted between horizontal guides on the outside of the main frame A' of the machine, by pins f on their ends, which pins enter slotsf in the frames F. The slots f are, for a portion of their length, parallel and horizontal, and are divergent for the remainder, and each of the frames F is coupled to the strapf of an eccentric, f, on one of the shafts which reciprocate the heads longitudinally during the rotation of said shaft. Byreason of the relation of the pinsfof the grippers to the slotsf vertical movement is imparted to the grippers F during the traverse of the pins through the inclined portions of the slots, coincidently with the horizontal movements of thesliding frames F and die-boxes D, the grippers being clamped upon the nut blank, and there remaining sta tionary during the shearing and punching operation, at which period the pins are within the parallel portions of the slots.
For the purpose of compensating for wear of the clamping-facesofthe grippers, as well as to admit of adjustment to blanks of different widths, each of the grippers may be provided with an adjustable clamping-jaw, secured by bolts passing through vertical'slots, so that its distance from theface of the gripper may be regulated as required. The cylindrical cores punched from the nuts pass out through the central perforations of the abutment-dies (1 into openings in the die-boxes communicating therewith, from which they fall on the inward traverse of the heads into suitable receptacles, and the cut and punched nuts are pushed off the lower gripper by a discharger, G, the same consisting of a rod parallel and adjacent to the clamping-face of the lower gripper, and having two downwardlyprqiecting arms, the lower ends of which are pivoted to the main frame. The discharger is drawn clear of the gripper, on the upward movement ofthelatter, by a spring, g, and on its downward movement is swept across the clamping-face, thereby pushing off the nuts which rest thereon, by a pin,f*, which projects from the lower side of the gripper and bears against a lever-arm, g,formed upon or secured to the lower end of one of the supportingarms of the discharger.
In the operation of the machine the nutblank, which is clamped between the faces or the adjustable jaws of the grippers, is sheared into a series of nuts by the edges of the abutmentdies in the inward traverse of the heads, and the holes in the series of nuts are simulta neously punched, the punches in each die-box acting against the. abutments in the other.
.Upon the outward traverse of the heads the nuts are pushed off the punches by the stationary strippers and delivered to the lower gripper, from which they are discharged into areceptacle provided for them, and a new blank being introduced, the operation is repeated.
It will be understood that in practice a pair of die-boxes and stripper-bars, each fitted with dies,aud strippers, as described, is to be provided for each diameter of nuts which it is desired to manufacture, and the insertion and removal of these parts can be readily and speedily effected whenever required. It will be further obvious that the machine is equally adaptable to the manufacture of washers from blanks of less thickness than those used in the manufacture of nuts without departure from the spirit of my invention.
IIO
1 am aware that the formation of nuts from a bar or blank by the action of two sets or series of altern ately-arran ged cutting and punching dies upon said blank while held between movable clampin g-plates, as in the patent of R. Griffith, No. 16,142, dated December 2, 1856, is not new, and do not therefore broadly claim said devices, either singly or combined. The machine of said Griffith patent, however, differs substantially from my invention in the particular that it does not embody the facilities for ready adaptation to the manufacture of nuts of different desired sizes which I provide by myremovable die-cases,each carrying its adjusted series of shearing and punching dies, as also in sundry details of the mechanism employed and specifically claimed by me.
I claim as my invention and desire to secure by Letters Patent- 1. In a nut-machine, a multiple shearing and punching device consistin gof two series of dies arranged in separate die-cases, each of said series being composed of alternate cutting-off and punching diesplaced side by side in said cases, and mechanisni to actuate said series of dies reciprocally toward and from one another, substantially as set forth.
2. In a nutmachine, the combination of a series of alternate shearing and punching dies, a case or die-box,a backing-plate, and aclampin g cap or cover, substantially as set forth.
3. In a nut-machine, the combination of a movable series of alternate shearingandpunehing dies and a stationary series of strippers for discharging the cut and punched nuts, said strippers being arranged in pairs on each side of and parallel to each of the punching-dies, substantially as set forth.
4. In a nut-machine, the combination of a frame, a head or carrier fitted to guides therein, a die-box secured removably in said head and carrying a series of alternate shearing and punching dies, and a driving-shaft by which reciprocating movementis imparted to the head or carrier, substantially as set forth.
5. In a nut-machine, the combination of a pair of heads or carriers, each provided with a series of alternate shearing and punching dies, a pair of grippers or clamping-jaws intermediate between the heads or carriers, and a pair of sliding frames having inclined slots receiving pins on the ends of the clamping-jaws, substantially as set forth.
6. In a nut-machine, the combination of a pair of reciprocating grippers or clampingjaws and a discharger traversingintermittently over the face of one of said grippers, sub stantially as set forth.
7. In a nut-machine, the combination, with a pair of heads or carriers, each provided with a removable die-case having secured within it a series of alternate shearing and punching dies, of mechanism bywhich said die-cases are actuated reciprocally toward and from one another, stationary st-ripper-plates for relieving the punching-dies, and a pair of grippers or clampin g-jaws reciprocated between the heads and at right angles to their line of traverse, these members being combined forjoint operation substantially in the manner and for the purposes set forth.
