NAIL-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 342,929, dated J'une l, 1886. Application filed December 16, 1885. Serial No. 185,810. (No model.)

To all whom it may concern.-

Beit known that I, FREEBORN F. RAYMOND, 2d, of Newton, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Nail-Making Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention is an improvement upon that described in my Letters Patent No. 317,199, and upon that described in the application of A. O. Towns and myself, filed November 27, 1885, Serial No. 184,048, for nail making and distributing machines; and it relates especially to the mechanism or devices for varying the length of nail severed or cut from the wire.

Referring to the drawings, Figure 1 is a view in front elevation of a machine having my invention. Fig. 2 is a view in vertical section and elevation of the portion of said machine to which my invention relates. Figs. 3, 4, and 5 are detail views; and Fig. 6 illustrates a modification.

A represents the frame of the nail-making machine. It supports the feed-rolls a and a. They are like those described in the said application of Towns and myself, and they are operated by mechanism, substantially as therein set forth, to vary the feed of the wire. Below the feed-rolls is a fixed block, o in which is a feedway or passage, a for the wire, and below this stationary block there is arranged the movable block 13, which has a passage or feedway a, in continuation of the feedway of the block a. This block B is movable vertically in relation to the block a in suitable guides or ways, either-by means of a spring, I), which may surround it and bear against the shoulder Z) thereon and against the shoulder b of the block a", or it may be moved vertically by means of a screw, as represented in Fig. 6. For the purposes of the invention, however, it is immaterial how this block is provided with a vertical movement. There is arranged to be reciprocated across the lower edge of this block, in a suitable passage or guideway, G, in the block 0, the nail cutting and carrying devices, and these comprise the block 0, adapted to be positively reciprocated by means of the link 0 lever 0 and cam c. This block 0 supports the die-pieces 0 which preferably are shaped in side and end elevation as represented in Figs. 2 and 3. They form a passage or feedway, e in continuation of the passage (4". The die-pieces are fastened to an extension, 0, of the block 0 by dowelpins 0 passed through holes therein and the covering-pate c", which is screwed to said extension c, and when thus secured the inclined surfaces 0 of the die-pieces project into the guideway or passage 0. Above the die-pieces c is a wire-cutting plate, D, which has a hole, d, adapted to be brought in line with the feedway a. This plate D is made vertically movable in the block 0 in any desired way, and I have represented it as provided with the tongue-projection d, which enters a recess of correspondingshapeintheblock. This tongue may have a hole for the reception of a steadypin, and it has a screw-hole for the reception of the screw-spindle d, carried by the block 0, and by which it is moved vertically. A checknut, d, may be used for locking the screw after the plate has been moved to the desired position. The plate D or block B may also have a sleeve or tube, (1*, arranged so that its passage shall be in continuation of the hole d, and having a slightly-tapering exterior arranged to shut into the slightly-tapering hole of the die-pieces a, so that the tube can have a vertical movement in the passage as the plate D and block B are raised or lowered in relation to the portion 0 of the block.

In the operation of severing a nail or nailblank from the end of the wire the wire is fed by the feeding devices through the feedway a (0* to the lower edge of the diepiec'es 0 coming in contact or very nearly in contact with the lower surface of the guideway G. The movement of the block 0 will cause the cutting-plate D to sever the wire on the line of its upper surface as the block and plate are moved horizontally past the block B, and in order to secure (with a proper feed) nails varying in length it is only necessary to adjust the height or position of the block B and that of the cutting-plate D in relation to the section or portion 0 of the block. Forinstance, if it is desired to cut a short nail or blank from the wire, the feed is adjusted to feed thelength of wire desired, and the cutting-plate D is moved downward in its holding-block to the desired position, and the block B also moved downward to correspond or so that its under surface shall come in contact with the upper surface of the plate D, and upon the forward movement of the block The result is that the nail will be severed by the cutting action of the cutting-plate D as it moves by or past the end of the feedway. If it is desired to obtain a longer nail, the feed is adjusted, the block B is moved upward as well as the cutting-plate D, and as that changes the length of the hole in the carrying-block it is obvious that upon the movement thereof alonger nail or blank will be cut. I

The cutting-plate may be made of hardened steel, and the block B provided with a hardened-steel die-plate.

To point the nail or blank after it has been severed from the wire, I have arranged the pointing-cutters F to project into the guideway 0 upon a line with the bevel or inclination of the die-plates. These cutters are fastened in place by screws or in any other way, and are so arranged as to sever from the lower end of the nail or blank held in the die such portions thereof as shall project on either side from the two side surfaces of the die, and the waste or sections of the blocks thus removed drop from the guideway through the escapepassage f. These cutters are similar in form and arrangement to the cutters shown and described in my Patents Nos. 31 7,199 and 317,851, and they bear the same relation to the nailcarrying blockthat is, they are stationary, and are inclined in relation to each other, and the nail-carrying block is arranged to carry or move the nails past them.

The cutters may have any inclination, and may be arranged upon the same line, or one in advance of the other, as may be desired, and they of course are arranged to conform to the inclination of the lower portion of the die-plate. The carrying-block 0 may be arranged to carry the nail or blank by or past the cutters, and then immediately back to a passage in the throat, arranged in continua tion of the passage a, by which it is discharged from the machine; but the construction I prefer and have illustrated is adapted to feed the wire blank past the cutters to the throat G, in which the driver or reciprocating rod g is arranged. This throat G is arranged in a nozzle, 9, and so as to come in line with the hole or passage a of the carrier-block 0 when it has been moved forward past the cutters.

The reciprocating rodor driver is operated by a spring and lifting-cam or by a cam only,

as may be desired. In the drawings I have represented a spring and lifting-cam, and they are so timed that upon the movement of the nail into position beneath the rod 9 the rod is released and the spring forces it through the passage a of the carrying-blocks, and through in described. I would say, however, that for the purposes of this invention I do not confine myself to a special form of receiving and delivery block, but may use any adapted to receive nails from the throat in successive order and transfer them for delivery.

I would further state that so far as the cutting and severing devices are concerned they may be used in a nail-driving as well as in a nail-making machine, where it is desirable to make and drive nails of varying lengths.

In operation, the cutter-block D and the block B are adjusted to cut nails of the length desired, and upon the operation of the machine the wire is fed by the feed-roll through the feedway cl into the hole in the cutter-block D and dieblock, and upon a horizontal or forward movement of these parts the cutter-block D severs the nail-blank or nail from the end of the wire, and byacontinued forward movement the wire-blank is carried past the cut ters, whereby its lower end is brought to a position beneath the rod which is then released to drive or move the nail from the carrier-block through the throat into the feedway-hole of the nail receiving and delivery block H. The rod is immediately lifted and the carrier-block returned to its original position to receive the section of wire which forms the next nail. Meanwhile the nail receiving and delivery block has been operated, as (lescribed in the said application referred to, to bring another nail-receiving hole in line with the throat, and the operation proceeds as bcfore.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1.
