ROBERT GRIFFITHS, OF PHILADELPHIA, PENNSYLVANIA.
NUT-MACHINE.
Specification of Letters Patent No.
To all whom it may concern: y
Be it known that I, ROBERT GRIFFITHS, of the city of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Nut-Machines; and I do hereby declare that the following is a full, clear, and eXact description of the same, reference being had to the accompanying drawing and to the letters of reference marked thereon.
My invention relates to improvements upon a machine for making nuts, for which a patent was granted to me on the thirtieth day of October A. D. 1855, and consists in so arranging the cutters and punches of said machin-e that they can be removed and replaced with facility, also in the peculiar construction of a stripper plate.
On reference to the drawing which forms a part of this specification, Figure 1, is a ground plan of my improved nut machine, Fig. 2, a sectional elevation on the line 1 2, Fig. 1, Fig. 3, a transverse section on the line 34L Fig. 2, Figs. 4 and 5 detached views, showing t-he stripper and presser.
The same letters of reference allude to similar parts throughout the several views.
A is the base plate of the machine, B and VB the two standards in which turn the shafts C, D,'E and E. The shaft O is driven by a belt or suitable gearing in the direction of the arrow Fig. 2, and on this shaft is a cog wheel F which gearing into the wheel G on the shaft E, into the wheel I-I on the shaft E, and into the wheel I on the shaft D causes the respective shafts to turn in the direction of their arrows, all the shaft-s turning at the same speed.
On the shaft O are two cams c, c, which operate the lower table J, the latter being arranged to slide in lugs b, b, cast or otherwise secured to the inside of the opposite frames B and B. On the shaft D are also cams cl, (Z, which as the shaft revolves, depress the upper tables K which slides in lugs 7c, 7c, the upward movement of the table being accomplished by means of suitable springs. Both upper and lower sliding tables are furnished with dovetailed grooves for receiving dies m and a the size of which are varied according to the form of nuts to be manufactured.
Between the upper cro-ss bars a, e and and the permanent lug h and cross bar g below, slides the plate M and plate P with its hinged lid L and the punching bars N, N,
16,142, dated December 2, 1856.
N, and cutting bars O, O, O. The upper plates P and M. The bar c bears directly on the hinged lid, and the bar f on the punching and cutting bars. The forward movement of the plate M is effected by the cams p, ya, on the shaft E bearing directly against the end of the plate, and the backward movement by the same cams bearing against the yokes g, g, the ends of which are fastened to the plate, the other ends sliding in orifices in the cross-head Q. The forward movement of the plate P is effected by the cams r, 1, o n the shaft E, and the backward movement by the cam t on the same shaft bearing against the yoke S, one end of which is secured to the plate P the other to the crosshead Q the ends of which slide in slots in the opposite frames B and B. It will be thus seen that the plate P with its punching bars N has a sliding movement, independent of that of the sliding .plate M with its cutter bars O.
On the end punching bar N is a cutter u the object of which will be apparent hereafter. R is the stripper plate, the horizontal portion of which is arranged to slide between the top of the permanent bar c and a plate against which bear the punching and cutting bars, the stripping portion of the plate consists of three projections passing between the cutter bars, the projections having holes through which pass the round portions of the punching bars. On the opposite end of the machine are also, a series of sliding cutting bars O, O, O, and punching bars N2, N2, N3, the ends of the punching bars on one end of the machine, coinciding with the ends of the cutting bars on the opposite end of the machine and vice versa, and the punching portion of the punching bars enter ing the orifices in the cut-ting bars.
On the end punching bar N3 is a knife u similar to that above referred to in reference to the bar Y. These punching and cutting bars slidebetween the two plates S and T which move together between the cross bars f and g which are so attached to the frames B and B, as to be capable of yielding vertically to a slight extent.
Secured tothe plates S and T and coinciding with the punching bars N2, N2 and N3 are the stripping and pressing plates w, w which are divided in the middle as seen in Fig. 3, the punching port-ion of the bars passing between the openings at the junction of the said plates. The upper plate S is so hinged to the plate T that both move together the forward movement being effected by the cams y, y, on the shaft E bearing against projections on the lower plate T, and the backward movement by the salne cams bearing against the yokes 00, x, attached to the same plate. The punching and cutting bars on this end of the machine, are in other respects similar and similarly arranged and driven to those already described in reference to the other end of the machine; in the latter however there are but two independent movements namely those of the cutting and punching bars while in the latter there are three independent movements, namely those of the cutting bars, punching bars, and pressing and stripping late. P Although I have shown the two ends of the machine with different descriptions of pressing and stripping plates, I wish it to be understood that both ends may be alike, and either of the plans adopted.
Operation: Supposing the machine to be set in motion and the movable parts to be in the position shown in Fig. 2, with a bar of heated iron introduced through an orilice in the frames, the first movement that takes placewill be that of the table J which by the action of the cams c, C, rises until the top of the die is level with the bottom of the punching and cutting bars, simultaneously with the rising of the table J, the table K by the action of the cam d descends until the heated bar of iron is confined be- -tween the upper and lower dies m and n.
The opposite cutter bars now advance simultaneously, and with them the knives n n causing the heated bar to be severed into siX blanks. The square blocks or blanks of heated iron are now acted upon by the opposite punching bars which also advance simultaneously perforating the blanks. The points of the punches have now entered a short distance, into the orifices of the cutting bars, and both continue to advance until the shoulders on the punching bars have forced the strippers against the nuts, so that the latter become pressed between the ends of the cutter bars, and the stripper plates R. As the edges of the blanks during the above operation were confined in one direction by the dies m and n, and in another direction by the sides of the cutter bars, it is evident that the holes in the nuts will be central, while the edges and faces will be perfectly uniform and smooth. The opposite punching bars now recede so that their ends are, by means of the stripper R, released from the nuts, the cutter bars now also recede, the table J descends, and the table K rises, so that the machine is again in the position shown in Fig. 2, when a repetit-ion of the above movements takes place. The stripper R is allowed to have a slight sliding movement as before remarked; the object of this is in order that it may be withdrawn a short distance with the receding punching bars, so as to allow another heated bar to be readily introduced, at the same times it serves on the advance of the punching bars as a medium for squeezing up the blanks as before described.
The modified form of strippers and pressers shown in Figs. 2, 3 i and 5 although not absolutely necessary for the due performance of the machine, possesses the advantages on account of the divisions at the orifices, and yielding bars f and g of separating should the end of the punches be burred up; the strippers w also can be easier removed and replaced than the strippers R.
Should both ends of the machine be furnished with the stripping and pressing plates w, w the result would be precisely the same as the only difference between the two arrangements is this, that the stripper R slides on a permanent portion of the frame, while the strippers and pressers w, w, have a movement independent of the cutting and punching bars.
It should be understood that the pieces `forced from the hot iron by the ends of the punching bars into the orifices on the ends of the cutting bars pass from thence through another orifice communicating with the first to the ground.
By removing the cross bars a e and f, and turning up the hinged lid L the whole, or any one of the punching and cuttings bars, may be removed and replaced with facility, the same may be said of the bars on the opposite end of the machine.
What I claim and desire to secure by Letters Patent is,
1. The manner substantially as herein set forth of securing the punching and cutting bars between the sliding plates for the purpose specified.
2. The combining of the punching and cutting bars, with the strippers, the said strippers being whole or divided and operating in either of the methods specified.
ROBERT GRIFFITHS.
