SPECIFICATION forming part of Letters Patent No. 673,814, dated May '7, 1901.

Application filed May 14, 1900.

To all whom, 7115 may concern,.-

r Be it known that I, PERLEY R. GLASS, of Quincy, county of Norfolk, and State of Massachusetts, haveinvented 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.

The present invention relates to an eyeleting-machine, the object of the invention being to obtain a machinein which a number of eyelets may be set at one operation, the machine punching the stock and feeding and setting the eyelets automatically. For this purpose the machine embodying the invention is provided with a gang of punching-tools properly arranged to punch a number of holes at a single operation in such position relative to the material and to each other as may be desired and a coperating punching member and a gang of setting-tools for setting the eyelets in the previously-punched holes, the machine also being provided with means for separating the punching members, (the gang of punching-tools being` considered as one of said members and the coperatingpunching device being the other of said members,) in order that the material may be accessible to the settingtools in the setting operation. The punchingtools may advantageously be arranged to cooperate with the setting-tools in the setting operation and are herein shown as provided with tubular punching projections surrounded by annular clenching-dies and so arranged with relation to the gang of setting-tools that the said annular dies will operate to upset or clinch the eyelets in response to the operation of the setting-tools.

The punching-tools are herein shown as stationary with relation to the machine and projecting downward from a portion of the frame, while the coperating punching member comprises What may be termed an anvil arranged to have a vertical movement toward said punching-tools,so thatwhen the material is held in the machine between the said members the upward vertical movement of said anvil will force the material against the cutting edges of the punches, thus punching out a series of holes. The setting devices are arranged to reciprocate vertically and to move Serial No. 161663. (No model.)

upward toward the punching-tools after the punching operation is completed, the anvil in the meanwhile being moved vertically downward and also laterally with relation to the line of punching, so as to travel out of the path of the setting devices and permit the same to come in contact with the material which is between them and the punchingtools. i

When the machine is in its normal condition before being started, the anvil is separated from the punching-tools and the material may be placed upon the surface of said anvil or held against the cutting edges of the punching-tools, as may be more convenient, and when the machine is started the anvil will travel upward to punch the material, which will then be held with the punching-tools in the several openings, while the anvil moves away, the setting devices then moving toward the punching-tools to insert and set the eyelets, the usual eyelet-feeding device being employed to provide the setting devices with eyelets.

In order to facilitate the setting operation, it is desirable thatthe punching-tools should be externally tapered and caused to project beyond the surface of the material after the material is punched in order to guide the eyelets into the openings in the material. To accomplish this, the anvil may be provided with a covering of rawhide, which will properly support the material, but permit the punch to penetrate said covering slightly, so that the material in the punching operation will be forced up along the tubular punching-tools, the ends of which thus project beyond the surface of the material, so as to guide the eyelets into the holes, or if the supporting-surface of the anvil is of impenetrable material it may be provided with annular channels to receive the cutting edges of the punch.

Figure l is a front elevation, partly in section, of a machine embodying the invention; Fig. 2, a side elevation of the same, partly in section and Fig. 3, a detail view showing the parts in a different position from Fig. 2.

The punching-tools a, or punches, as they will be hereinafter referred to, are shown as provided with annular clenching-shoulders IOO ceive the eyelets.

a2 and are supported in an" overhanging projection A2, which forms part of the frame A of the machine. There may be any number of the said punches desired, according to the number of eyelets to be set by the machine, there being four of such punches herein shown, although in some cases live or six or any other number may be employed. Each of the said punches is tubular and provided with a cutting edge, and, as herein shown, the punching-tools are screw-threaded in the projection A2, which -is provided with channels A3 for the egress of the pieces of the material punched out, and, if desired, the said projection may be provided with a box A4 to receive the said pieces of material and prevent the same from being scattered about.

In treating of the machine as a whole 'the said gang of punches may be considered as a single punching member, the punching operation being completely performed by the cooperation with said member of a second punching member b, which consists of an anvil, be-v tween which and the punching member lirst named the material isintroducedin the punching operation. As herein shown, the said punching member b, or anvil, as it Will be hereinafter referred to, is supported upon a pair of vertically-movable arms or columns b2, each connected by means of a link 3 with a lever b4, pivoted upon a cross member b5, supported by the frame A and connected at its opposite end with an eccentric-strap b, carried by an eccentric B2 on the main shaft B. The rotation of the said shaft, therefore, will produce a reciprocating movement of the said anvil b, so that if the material is placed in position between the same and the Apunches a a line of holes will be punched therein. In order to complete the operation, it isnecessary that an eyelet should be inserted in each hole and clenchedf therein, and for this purpose the machine'is provided with a set of clenching-tools c, each of which has a clenching-shoulder o2 and depressible pin c3, projecting upward to pick up an eyelet from an eyelet-feeding device d. Prior to the setting operation it is necessary that the cooperating punching members should be separated from each other, so that the eyelets may be presented to the material by the eyeylet-setting devices and clenched by the cooperation of said setting devices with each other., The reciprocating movement of the 'member b properly separates the said parts, so that the openings in the material may re- When, however, as herein shown, the punching-tools a are arranged to also cooperate in the setting operation, or, in

yotherfwords, to constitute setting members as well yas punches, it isnecessary that the said setting devices should move toward the punches' a, thereby occupying the position previously occupied by the anvil b in the punching operation. It is necessary, therefore, that the lsaid anvil b should not only move away from the punches* c, but also out the main shaft B.

of the path of the setting devices c, and for this purpose the said anvil is herein shown as arranged to have a laterally as well as a longitudinally reciprocating movement in the operation of the machine. As a convenient means for producing such lateral movement the arms b2 are shown as provided with projections 67, each having an 'antifriction-roll b3, adapted to engage the walls of curved or cam shaped guide-grooves A5, formed in wings or projections from the frame A, the curvature of such grooves being such as to cause the anvil in its downward movement to travel laterally with relation to the punches a out of the path of the reciprocating setting devices c, which then move toward the said punches, as best shown in Fig. 3.

As herein shown, the lateral movement of the anvil b is forward with relation to the machine, the anvil when down thus being in a convenient position to receive the material, it being practicable to provide said anvil with suitable gages, so that the material may be correctly placed and held in position during the upward movement of the anvil.

As herein shown, the anvil is provided with a supporting portion bifor the punches, this supporting portion being advantageously made of rawhide, which affords a firm support for the material to be punched Without resisting the downward movement of the kpunch exceeding that required to punch the material, which material is thus not only penetrated by the punch, but forced upward along the same, so that the punch projects below the lower surface.

As indicated7 the punches are tapered externally, and in the operation of the machine as the anvil recedes the material is left upon the punches with the punches protruding, the setting devices then operating and presenting the eyelets to the punches, the tapered outer surfaces of which guide the eyelets into the holes. The eyelets may be fed to the setting devices in any suitable way, the machine being herein shown as provided with a reciprocating chute which constitutes the eyeletfeeding device d, the said chute having a plurality of raceways d2, each having the ordinary spring-controlling device at the end, so that the eyelets will not slip out of the said chute until engaged by the fingers c8 of the setting devices c. The said eyelet-feeding device is arranged to move forward into the path of the setting devices c and to remain in its forward position long enough to have an eyelet engaged by each of the fingers c3, then receding and leaving the eyelets upon the said fingers, substantially as in eyeletingmachines heretofore used.

To produce the reciprocating movement of the eyelet-feeding device d, the said feeding device is shown as mounted on guides d3, se-

lcured to the frame of the machine and connected by a rod d4 with an eccentric B3 upon The several raceways d2 are adapted to receive eyelets from a hopper IOO IIO

d5, having an opening for each raceway, the openings being so shaped as to cause the eyelets to pass ont in the proper position. The setting devices c are shown as mounted on a carrier c4, adapted to travel vertically in a suitable guide-support formed in the frame of the machine between the columns h2, which support the anvil, the said carrier being connected by a link c5 with a lever c6, which may conveniently be pivoted upon the cross-member b5, which carries the levers b4, hereinbefore described, the said lever c6 being connected with an eccentric-strap c7 on an eccentric B4 on the main shaft B.

As shown in Figs. 2 and 3, the eccentrics B2 and B'L are arranged substantially opposite to each other, so that the downward and lateral movement of the anvil takes place during the upward movement of the setting devices, the two parts being so arranged as to just clear each other Without loss of time in the operation.

The feed-chute is arranged to travel forward just after the anvil travels downward, so as to come into the path of the setting devices at the proper time and present the eyelets thereto.

By the use of the gang of tools, each of which combines a punch and setting device, the necessity for all feed mechanism for the material is obviated and the Whole operation is performed with only three movable members-namely, the anvil, the reciprocating settin g-device carrier, and the eyelet-feed chute. Furthermore, the movements may be imparted to the several parts from a single shaft without any substantial intermediate mechanism, so that it is practicable to make a machine not only very rapid in operatiombut also of extreme simplicity. tended to limit the invention to the specific construction herein shown and described, although such construction is believed to be the most practical embodiment of the invention, since modifications may be made Without departing from the invention.
