SPECIFICATION forming part of Letters Patentl No. 701,261, dated May 27, 1902.

` Application filed March 25,1901. Serial No. 52.754. (No model.)

To @ZZ whom it may concern.:

Be it known that I, PERLEY R. GLAss, of Quincy, county of i Norfolk, and State of Massachusetts, have invented an Improvement in Eyeleting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

Thepresent invention relates to an eyelet- Io ing-machine, and is embodied in amachine in which the material is fed laterally by the punch after the punching operation, the eyelets being set by cooperating setting devices independent of the said punch.

The object of the invention is to obtain the advantages (rapidity, dac.) of a machine in which the punch itself is utilized as one of the clenching-tools and at the same time to adapt the machinefor certain classes of work zo where it is desirable or essential to punch a larger hole relative'to the size of the eyelet than is practicablel where the punch itself contributesin the setting operation.

In accordance with' the invention the upper o 5 setting device is so arranged as to be out of the way of the punch during the rfeeding op-` eration, but adapted to be moved to a position directly over the punched hole at the end of the feeding operation, the punchhavgo ing in the meanwhile risen, so that the set can take its place.

The device may conveniently be arranged so that the set is moved out of the way by engagement with the punch in the feeding movement thereof and brought back toits properposition by means of a spring or equivalent device, and the punch may be utilized as a gage to insure that the setting device will be arrested directly over the opening.

4o The punch may, furthermore, be arranged to engage the said setting device in such a manner as to support the same against the thrust of the cooperating setting device or lower set, which presents the eyelet to the previously-punched material and cooperates in the setting or clenching operation. As herein shown, the punch is arranged to move forciblyinto contact with a Work-support or anvil, in conjunction with which it perforates the material, and then to rise or move back suf- 5o iiciently to be released from the anvil, but not from the material, the lateral feed movement then taking place, which movement ceases when the punch is directly over the lower setting device. The upper setting device normally stands over the lower setting device, but is yieldingly held in such normal position, as by a spring, so that when the punch makes its lateral feed movement it will engage the said setting device and move the same aside.- The punch then rises and in rising releases the said setting device, which springs into position, and the punch member is preferably adapted to engage a horizontal shoulder which forms part of the setting device and to remain stationary in engagement with the said shoulder during the setting operation, so as to resist the upward thrust of the lower setting device. The upper setting device is further preferably provided with a vertical shoulder adapted to engage the side of the punch member, so as to be positioned thereby, the said setting device thus being positioned or gaged to stand directly over the opening in the material, which 7 5 is of course below the punch at this period of the operation.

As herein shown, the machine is provided with a presser-foot which drops into engagement with the material at the end of the feed movement to hold the same stationary during the setting operation and during the lateral return movement of the punch, and the setting device may conveniently be supported in the said presser-foot, being movable with relation thereto and provided with a restoring-spring, as stated.

Figure l is a front elevation, partly in section, of a machine embodying the invention. Fig. 2 is a plan view of the feed-table or worksupport yand the presser-foot and upper set; and Figs. 3, 4, and 5 are details on a larger scale, showing the parts in different positions to illustrate the operation of the machine.

The invention is herein shown as embodied in a machine substantiallythe same in its general construction as that shown and described in a prior application iled by me .I une 15, 1899, Serial No. 720,603, and only so much of said machine is herein shown as is neces sary to illustrate the novel features of the present invention.

The machine embodying the invention is provided `with a punch a, supported at the end ofa reciprocating rod a2, which is mounted in a laterally-movable carriage A, the reciprocating movement of the punch performing the operation of perforating the material, while the lateral movement of the carriage feeds the perforated material to a position to be operated upon by the setting devices. The means for producing the lateral movement of the carriage are not herein illustrated in detail, the parts which are indicated being substantially the same as those shown and described in the prior application labove referred to. The reciprocating movement of the punch is accomplished through the action of a shaft a3, which is provided with an eccentric-pin a4, coperating with the punch, the said shaft being oscillated by means of a segment a5, connected with a lever a, which is acted upon by a cam a7, the said cam being shown as a groove or channel in a disk mounted on the main shaft B Vand adapted to receive a cam-roll at the end of the said lever. The said cam is so shaped as to produce in the first part of the cycle of operations a rotation of the shaft a3 which is sufficient to force the punch toward the anvil or worksupport b in order to perforate the material and to continue its movement sufficiently before dwelling to carry the eccentric-pin beyond the axis of the shaft far enough to produce a slight upward movementof the punch, as indicated in Fig. 4, thus releasing the punch from the anvil, but not from the material. At this period in the operation the punch remains stationary so far as relates to its reciprocating movement, but is carried laterally by the frame or carriage A, the movement of which is such as to carry the punch to the position shown in Fig. 4, where it stands directly over the lower setting device c, which is arranged to reciprocate and in its movement toward the material to pick up an eyelet in the usual way from a suitable feeding device.

To coperate with the setting device c,which will be hereinafter referred to as the lower set, the machine embodying the invention is provided with another setting device d, which will be hereinafter referred to as the upper set, the said setting device d being arrangedto move into a position over the hole punched in the material before the lower set rises to present and clench the eyelet. This movement of the upper set takes place during the upward-movement of the punch away from the material 4and may advantageously be produced by a spring or the equivalent, the upper set d normally standing over the lower set, but being pushed out of the way by the punch in the .feed movement thereof. As herein shown, the said upper set CZ is supported in a presser-foot e, the function of which is to hold the material rmly in position except during the feed movement thereof, and the said set may be mounted in aguidegroove in the said presser-foot and provided with a spring d2, the tendency of which is normally to move the said upper set toward the place where the punched opening in the material is left at the end of the feed movement. The normal position of the upper set d is shown in Fig. 3, the punch a being shown in the said figure as just at the end of the punching operation. The punch at this period in the cycle rises slightly and moves laterally,

the presser-foot e at the same time being lifted,

as described in the prior application above referred to, and the punch, carrying the material with it,then moves to the position shown in Fig. 4, where it stands directly over the lower set c. In such movement the side of the punch rod or carrier 0.2 engages a portion of the set d, forcing the same out of the way against the stress of the spring d2, and as the presser-foot e descends and the punch ct rises the upper set CZ becomes disengaged from the punch and snaps back to the position shown in Fig. 5. In this position the said set is directly over the lower set c, ready to coperate therewith in the clenching operation, as shown in said figure, where the parts are in the position assumed during the operation of clenching.

In order firmly to support the upper set d during the clenching operation, it is practicable to utilize the punch-rod a2 itself, the said punch-rod being shown in Fig. 5 as arrested in such a position as to overlie a shoulder d3, formed in the body of the set, the'upward thrust thus being borne by the punchrod, the movement of which is such that it will dwell in this position during the clenching operation. The punch-rod may also be utilized to gage the position of the set during the clenching operation, the set bei-ng herein shown as provided with a shoulder d4 to engage the side of the punch-rod when the said set springs into position, the said set thus being located by the punch-rod in the proper position, it being unnecessary, therefore, to delicately adjust the said set or to prov-ide the same with special means for properly locating it at the end of the spring action.

By the construction described the machine possesses all the advantages of a machine in which the feed movement is obtained by a lateral movement of the punch or setting devices, combined with the advantages of a machine in which the punch and one of the setting devices are combined in a single tool, it being necessary only to provide` the machine with mechanism for laterally moving one of the members, the movement of the upper set being produced by its engagement with the punch.

It is obviously not essential that the specific construction and arrangement of the u-pper set should be like that herein shown as lOO IOS

IIO

an illustration of the invention, it being necessary only to arrange the said upper set so that the punch can finish its lateral movement while the set comes into place as the punch rises. It is of advantage, however, to utilize the punch-rod as a gage and support for the set, which renders it practicable to utilize a spring for bringing the set into operative position and also renders it unnecessary to make the set strong and heavy or to provide it with a locating device of its own, as would be the case if the punch-rod did not perform the functions described.

It is not intended to limit the invention to the specific construction and arrangement of the various elements of the machine which has been chosen to illustrate the invention, since modifications may be made without departing from the invention, which is applicable to machines having the same general characteristics as the one described although varying widely in construction and arrangement.

I claim-- 1. The combination with the longitudinally andlaterally movable punch; of thelower set, the upper set normally standing substantially in line therewith; a spring normally holding said upper set, said spring yielding when the said upper set is engaged by the punch and restoring said upper set when the punch rises from the material; and a portion of the upper set adapted to engage the side of the punch to gage and position the upper set.

2. The combination with the longitudinally and laterally movable punch; of a presserfoot; a lower set; an upper set movably mounted in said presser-foot and provided with a restoring-spring, said upper set normally standing over the lower set but being moved out of the way by the punch; and supporting and engaging portions of the punch to support and gage the set during the setting or clenching operation.

3. In a setting machine, a lower set; :a presser-foot to retain the material during the setting operation; an upper set contained in said presser-foot; means for moving said upper set into alinement with said lower set after the punching operation; and a punch arranged to move laterally to feed the material, and to move said upper set out of alinement with said lower set.

4. In an eyeleting-machine, a punch adapted to punch and feed the material; a lower set; a presser-foot; and an upper set springsupported in said presser-foot and normally standing over the lower set, said upper set being moved out of the way by the punch in the feeding movement thereof.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
