MACHINE AND DIE FOR FORMING NAILSTRIPS.
SPECIFICATION forming part of Letters Patent No. 561,206, dated June 2, 1896.
Application iled June 5, 1895. Serial No. 551,708. (No model.)
To @ZZ whom it may concern:
Be it known that I, SOLOMON M. CUTTER, Y
a citizen of the VUnited States, 'residing at Nashua, in the county of .Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Dies for Forming Nail-Strips and in Machines in which they are Used; 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 the same. i
This invention relates to improvements in dies for forming nail-strips and in the machines in which they are used.
The object of the invention is to prevent the bending of the metal as much as possible while it is being punched into nail-strips, and thereby obviate the liability of breaking, kinkin g, or crippling the strip formed; also, to allow the formation of two continuous nailstrips-from a metal tape without waste of stock by overlapping or interlocking the shankform-ing portion of the dies, and to produce an automatic action of the machine used.
The essential part of the invention consists in the employment of an 4upper and a lower series of punches, one or both of which series are wholly or in part graduated in length, so that the longest of the punches will sever the strip and the remaining punches will enter the strip graduated distances, as fully described hereinafter.
The invention further consists inA novel combinations of elements and device and minor details of construction which operate to produce a machine in which said series of punches are used, which machine is automatic in its operation.
On the accompanying drawings,which illustrate my invention and form an essential part of this specification, Figure l represents a front elevation of one form of machine embodying my invention. Fig. 2 represents a side elevation of the same. Fig. 3 represents a central longitudinal section of the machine shown in Fig. l. Fig. 4 represents a bottom view of the upper series of punches. Fig. 5
represents a plan view of the lower series of punches and the device to clear the strip from said punches after it has been punched. Fig. G represents an enlarged longitudinal section, on the line A B in Fig. 4, of the block to hold the upper punches, showing the upper punches in side elevation. Fig. 7 repre- 55 sen'ts an enlarged longitudinal section, on the line C D in Fig. 5, of the block to hold the lower punches, showing the lower punches and their clearer in section. Fig. S represents a detail view of a portion of the mechanism 6o to produce the intermitting feeding of the strip to the punches. Fig. 9 represents an enlarged plan of a small portion of the metal tape after it has been acted upon by the punches and a portion thereof has been formed 65 into a nail, tack, or slug strip. Fig. 10 represents a central longitudinal section of the metal strip shown in Fig. 9. Fig. ll represents a cross-section on the lineE F in Fig. l0.
Similar letters refer to similar parts wher- 7o eve-r they occur on the different parts of the drawings.
In progressively punching the nail-strips from the metal tape by punching a short piece at once and then feeding the strip and punch- 7 5 ing another short piece it has been found that if the entire series of the punches are of even length and entirely sever the metal strip there will be a kink or bend formed inthe continuous portion of the strip at the place where 8o the end punch of the series severed the strip. For this reason it has been impossible hereto. fore to punch two continuous comb-shaped nail-strips from a metal tape without great loss or waste of stock, as it has been impossi- 8 5 ble to have the shank-termin g portions of one strip overlap or interlock to any great extent the shank-forming portions of the other strip,
Vand therefore it has been found necessary to have the metal tape nearly if not quite double 9o the width of the length of the shanks of the nails to be made from the nail-strip if it is Adesired to form two nail-strips from the metal In carrying out my invention I may use any suitable and well-known press now in com mon use; but l prefer to use the press substantially as shown in the drawings, which will be hereinafter fully described.
A series of upper punches a c a of the desired shape are used,which,in connection with the series of lower punches l) l1 l), sever the metal strip or tape c Ainto two comb-shaped nail or tack or slug strips d d without loss or waste of stock, as shown in Fig. 9. A part or the whole of either or both of these series of punches may be made graduated in length, as shown in lrig. (i, so that when the metal strip is acted upon by these punches the longest punches will entirely sever the metal strip and the remaining graduated punches will enter the strip more or less according to their length, and thereby partially sever the strip, as fully illustrated in Fig. lO. This partial severing of the strip prevents the formation of a kink or bend between the place where the last punch acted upon the strip and the remainder of the strip, which kink or bend if formed would tend to cripple the strip.
lVhen it is desired to form a nail-strip with projecting head-forming portions from a flat metal tape, I use, in connection with the series of graduated punches and the intermittinglyoperating feed-rolls c and f, having bearing in the frame g of the press or in the bracket g attached to the frame, a pair of upsettingrolls h and t', which press against the side edges of the metal tape and, in connection with the feed-rolls, compress and upset the edges of the tape, forming a projecting ridge c on each edge of the tape from which the heads of the nails to be cut are made. These upsetting-rolls are preferably provided with circumferential grooves 72, a11di,witl1in which the edges of the metal tape are upset, and the form of said grooves determines the shape of the ridge formed on the tape.
The lower punches are stationary and se cured in any suitable manner to the frame of the press. On the drawings the lower punches have been shown as being secured by means of the bolt 7a, which passes through a perfora tion in each punch of the series of punches and is screwed into the frame. The upper punches are secured in a similar manner, by means of the boltj, to the reciprocating head Z of the press. The head Z is reciprocatcd within guides in the frame by means of a crank m' on the driving-shaft m, the toggles n n, and the connecting-link o, between the toggles and the crank, in a manner similar to presses of this kind new in common use; but it may be reciprocated in any other and well-known manner.
The feed-rolls e and f, which are keyed or otherwise firmly mounted on their respective shaft e and f', are intermittingly rotated in bearin gs in the bracket g on the frame of the press by the following mechanism:
Upon the shaft c is loosely mounted the arm r, which is held upon the shaft by means of the collar c2. The arm o' is provided with the cam-recess r', within which the clamproll r2 and the spring r3 are placed. The action of this clamp-roll is such that the arm is free to be rotated on the shaft in one direction, but will clamp the arm and the shaft Iirmly together when the arm is moved in the other direction. The arm o' is oscillated on the shaft c by means of the connecting-rod s, attached to the arm and to a crank-pin t on the crank-disk t, which disk is irml y attached to the driving-shaft m. Thus it will be seen that by the oscillation of the arm /r an inten mitting rotation is imparted to the feed-roll e, which causes the metal tape to be intermittingly fed to the punches. The crank-disk is placed upon the driving'shaft m in such a relation to the crank on that the punches are out of the tape and the tape remaining sta tionary while being severed by the punches.
The upsetting-rolls 71, and are firmly attached to the respective shafts h2 and fi?, (shown in dotted lines in Fig. 1,) and a rotary movement corresponding to the movement of the feed-rolls is imparted to said upsettingrolls through the pairs of bevelgears 'u vu fu'. It will be seen that the upsettil1grolls 7L and not only upset the metal tape, but also assist the feeding-rolls in feedingthe tape to the punches.
The upsetting-rolls are provided with the circumferential grooves 7L' and t', which may be made in any suitable and required shape, according to the form of the longitudinal ridge to be made on the metal tape for the formation of the head-forming portion of the nailstrip.
The feed-rolls are preferably chamfered at their corners, se as to cause the under side of the heads of the nails made from the nailstrip to be inclined, and, if so desired, the upsetting-rolls may be made plain, so as to simply make a flat head with inclined under side when used with the chamfered feed-rolls.
The amount of the metal tape which is fed to the punches at each operation of the feedrolls is preferably equal to the number of the full-length punches in the series of punches containing the graduated punches-that is to say, if the series of the upper punches a c contain twenty punches and five of said series are graduated in. length the feedrolls will preferably feed the metal tape a distance equal to the length of the fifteen remaining punches of said series.
In order to adj ust the amount of metal tape fed by the feed-rolls, I make the connection between the arm o' and the connecting-rod .s' in the form of a nut i, which is adjustable toward and from the center of the shaft c on a screw ri in a slot in said arm, as shown in Fig. 8.
A suitable comb-shaped clearer is at tached stationary to the bed of the frame g and the upper punches are cleared from the nail-strip by being drawn upward through said clearer. A second and similar comb- IOO IIO
shaped clearer y is placed within the lower stationary punches in such a manner that it can be moved up and down through said punches to clear them from the nail-strip'. The clearer y is caused to move up and down once between each reciprocation of the upper punches by means of a cam m3 on the driving-shaft, which cam acts upon a pin or roll on the vertical rod z, attached in its lower end to a lever z', fulcrumed to the frame of the press. The end of the lever z is attached to a vertical rod z2, the upper end of which is itself attached to the clearer y. It will be seen that the action of the cam m3 causes the clearer J to force the nail-strip out of the lower punches after it has been punched.
I do not wish to confine myself to the use of this particular form of machine in carrying out my invention, as other machines of similar construction might be used to equal advantage without departing from my invention.
No claim has been made in this application to the nail or slug strip shown, as this forms the subject-matter of another pending application, Serial No. 584, 366, filed March 23,1896.
Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claiml. In a machine to form two continuous strips from a metal strip or tape, two series of overlappin g or interlocking punches graduated in length in part in the -line of the feeding of the metal tape to said punches, whereby said tape is separated into two continuous strips section after section without waste of material, for the purpose set forth.
