PIERCING AND eYELsTINe MACHINE.

SPECIFICATION forming part of Letters Patent No. 629,000, dated July 18, 1899-.

Application filed November 17, 1898. Serial No. 696,706. (No model.)

the following is a full, clear, and exact description.

This invention relates to a machine for piercing cloth and other similar and suitable material and for iixing eyelets in the holes formed by the piercers. The piercing and eyeleting is performed in one motion of the inachine, and one or any convenient number of holes may be simultaneously formed and eyeleted.

The accompanying drawings, to which I will hereinafter refer, illustrate the construction of the improved machine.

Figure l represents the complete machine in front elevation. Fig. 2 shows it in side elevation. Fig. 3 is a back elevation of part of the machine. Fig. 4 illustrates a part of .the brush which is employed in the eyeletbox to keep the eyelets agitated and to feed them into the chute or chutes. Fig. 5 is an enlarged View of a piercer and its accessories soon after it has commenced its stroke. Fig. 6 is a similar view of the same parts in different relative positions. Fig. 7 is a further illustration of the same parts when the piercer is at the end of its stroke and the eyelet is being riveted in place. Fig. 8 shows a modification. s Y

It will of course be understood that although the machine illustrated is represented witha multiplicity of piercers these improvements are equally applicable to a machine in which only one or any other convenient number of piercers are employed.

In its simplest form, then, the machine consists of a piercer which moves upward and pierces the cloth or similar material, then en- Y gages itself with an eyelet, passes farther and the eyelets.

Referring to the drawings, A is a frame,

within which the slide B is capable of reciprocating vertically. It may be operated in any desired manner, but preferably by the eccentrics C, secured to the main shaft D, or by means of cranks and connecting-rods. This slide is provided with a series of upwardly-projecting piercers E, each of which is formed with a thickened part or shoulder e, the function of which will be explained hereinafter. Above the piercers a seriesrof eyelet-chut-es Fis arranged, each chute opening into a `box Gr, which is mounted upon a shaft Hso as to be capable-of angular motion. At the top of the machine is a fixed series of dies or anvils I, these dies corresponding in number with the piercers.

The material to be pierced and eyeleted is placed upon the table J with the part to be pierced between the piercers and the overhangin g chute ends. The eyelets in the ends of thechutes are thus visible to the operator. The machine is then set in motion. The piercers pass upward and pierce the cloth or other material K, which is supported against the chutes F, the piercers passing through holes or openings formed in the chutes or between adjacent chutes or between proj eetions or horns formed on the chutes. Inany case the chutes are so formed that each of them presents an eyelet L to the point of a piercer, the eyelets being held with their flanged parts uppermost. The piercers after perforating the cloth enter the eyelets, as shown in Fig. 5. The ends of the chutes are now withdrawn and the piercers are free to continue their upward motion, carrying with them the cloth K Fig. 6 illustrates a piercer when this stage has been reached. The point of the piercer now enters an axial hole formed in its opposing die or anvil I, and the further movement of the piercer forces the eyelet into 'the cloth and clenches it, the clenching being performed between the face of the die I and the shoulder c of the piercer E. This is shown in Fig. 7. The piercers are now withdrawn and are freed from the cloth, the latter being held or drawn off by the table J. The eyelet-chutes are now returned.

The chutes are preferably operated and withdrawn by the link N, Figs. 2 and 3. The lower end of the link is pivoted to the slide B, and its upper end engages by a slot n with a pin, stud, or shaft O, which is connected with the chutes, they in turn being connected to the eyelet-box Gr, which, as before explained, is capable of angular movement around the shaft II.

IVith the various parts in the positions shown in Fig. 2 it will be seen that the first part of the upward movement of the slide B communicates no motion to the chutes. As soon, however, as the piercers have engaged with their eyelets the bottom of the slot n has come into contact with the stud O, so that continued motion of the link withdraws the ends of the chute in the direction of the arrow. Upon the return motion of the slide the chutes are not returned until the upper end of the slot reaches the stud O and draws them back to their former position. take place until the piercers are low enough to permit of the motion.

In order to insure that the chutes remain in their withdrawn position until it is time for them to return, a frictional device or brake may be employed. This may consist of an arm Q, one end of which is loosely connected to the stud O, while the other end is capable of passing under the spring-controlled clamp The friction between the clamp and the arm holds the chutes in their withdrawn position until the link N becomes operative.

An improved device for insuring the constant agitation of the eyelets in the box G whether the machine is working or not is represented in Figs. 1, 2, 3, and 4. This device also permits of the agitation being performed byhand. l`vlountedlengthwisewithinthebox and capable of reciprocating or sliding therein is a rod or shaft R. This rod carries wire or other brushes r. (See Fig. 4:.) Pivoted upon the side of the box is a crank-lever S, provided with a handle s and pulled constantly in one direction by the spring S. The lever is connected to the sliding rod R by the connecting-rod R. Upon the end of the box and in a plane at right angles to the plane of the lever S is mounted a second crank-lever T, one of the limbs of which comes below one of the limbs of the lever S, as clearly shown in Figs. 2 and 3. The other limb of the lever T is connected by a rod t to a short crank or eccentric upon the constantly-running rstmotion shaft U. As long as this shaft is running, therefore, the levers S and T have angular motion imparted to them, and the rod This does not R and the brushes r' are reciprocated. Should it be desired to agitato the eyelets when the shaft U is at rest, it can easily be effected by moving the lever S by the handle s.

The chutes may be of the usual construction and arrangement, with the exception .that their ends are formed to support the cloth during piercing; but it is preferred to form them with their channels approximately resembling a letter V in section instead of making the channels conform to the shape of the eyelet, as is usual. By the improved section shown in Fig. 5 the sides of the channel in the chute are straight and have no recesses which may become choked up. The risk of the eyelets becoming jammed is thus much reduced and the chute may be more easily cleaned when necessary.

Fig. 8 illustrates'in section a modiied form of chute in which the channel, although V- shaped, is formed with small flat ledges or flanges Y at its narrowest part to support the neck or narrow part of the eyelet.

The first-motion shaft U drives the main I shaft D by means of the pinion V and the wheel V', and the main shaft is thrown into gear by a suitable clutch WV, which is operated by a treadle X in the manner usual in eyeleting-machines.
