SPECIFICATION forming part of Letters Patent No. 581,854, dated May 4, 1897. Application filed May 20, 1896. Serial No. 592,364. (No model.)

To [1, whom it may concern:

Be it known that I, PERLEY R. GLASS, of Quincy, in the county of Norfolk and State of Massachusetts, have invented a new and useful Improvement in Eyeleting-illaehines, of which the following, taken in connection with the accompanying drawings,is a specification.

The present invention relates to an eyeleting-machine of that class in which a line or series of holes may be punched successively in the stock and an eyelet properly set in each hole, the operation of the machine to thus set a line of eyelets being completely automatic after the stock is inserted and the machine is started.

The object of the invention is to simplify the construction of the machine, whereby greater rapidity of operation is attainable, while the machine is less liable to get out of order and less expensive to build.

The operative parts of the machine embodying the invention comprise the punch and the eooperatii'lg eyelet sets, which parts are laterally stationary with relation to the frame and to each other, and the means for feeding the eyelets toa position to be operated upon by said eyelet sets, there being also an independent stock-feeding device arranged to cooperate with the other instrumentalities above named and timed to operate upon the stock just after the operation of the punch and before that of the eyelet sets to move the stock which has been punched to a position in which the hole punched therein is adapted to receive the eyelet.

The machine is provided also with connecting mechanism whereby the parts above enumerated are adapted to operate continuously during the operation of the machine, so that after the insertion of the stock and the starting of the machine a plurality of holes are punched and eyeleted automatically.

The various instrumentalities are so ar ranged in accordance with the invention that it is practicable to make the frame of the machine in a single integral piece wherein all the bearings and working surfaces may be formed by boring or planing, so that no expensive machine-work is required, the ar rangement, further, being such that all the operative mechanism is driven by a single shaft mounted in bearings in the said frame,

. I v IIIII-I i the other movable parts being mounted on rods or guide-bars which may be easily secured to the frame or provided with bearings therein.

The feed-chute, which operates in the usual way to present the eyelets to the eyelet-setting devices, is shown as mounted on guideways removably secured to cars orlugs at the side of the frame, the reciprocating movement of said feedchute, the movement of the punch, and the operation of the eyelet-setting devices all being provided by the rotation of a single disk mounted on the main shaft, as will be hereinafter described, the upper eyelet set being shown as fixed with relation to the frame, while the lower set has a vertical reciprocating movement to pick up the eyelet fromv the chute and present the same to the stock.

Figure 1 is a top plan view of a machine embodying the invention; Fig. 2, a section on the line 00 Fig. 1; Fig. 3, a side elevation of the machine, looking toward the left; Fig. 4, a vertical sectional elevation on the line at, Fig. 1; Fig. a detail showing the feed-table and feed-jaws.

The frame of the machine consists of a base portion A, which is provided wit-h an upright A, having forward projections A and A the former being bored to form a longitudinal bearing for the reciprocating lower-set bar H and the latter being adapted to receive and support a stationary upper set A, which consists of an anvil, against which the eyelet is forced by the lower set during the operation of upsetting said eyelet when it is inserted in the stock.

The main shaft B is mounted at one end in a bearing A in a post or support extending upward from one end of the base portion A and at the other end in a bearing A which is formed in an extension from the inner side of the portion A of the frame, as indicated in Fig. 1. The said shaft B is provided at one end with a hand-wheel B for manipulating the machine, if desired, and also with a driving-pulley B connected thereto preferably by a suitable clutch mechanism for the purpose of driving said shaft by power,

Secured to the projection A as by a suitable braeket, is a feed-table or work-support '1, adapted to support the stock and provided with a slot T to allow the lower set H to move upward and carry the eyelet into the opening previously punched in the stock and complete the operation by forcing the same into contact with the upper set.

In order to prepare the stock to receive the eyelet, a punch P is provided, secured to the end of an arm or lever P, pivoted at P and normally held in the position shown in Fig. 3, above the surface of the table T, by means of a spring P connected to the other arm P of said lever.

To produce the downward movement of the said punch in order to operate upon the stock lying on the table T, the end of the lever P is adapted to be engaged by a cam projection P from the surface of a disk E, secured to and adapted to be rotated by the main shaft B, the said disk also serving, as will be described, to operate the feed-chute and lower set. As the said disk rotates it is obvious that the projection P coming in contact with the under side of the lever P or a cam projection P therefrom, will produce a downward movement of the punch against the surface of the stock, so as to perforate the same. As the disk E continues to rotate, however, it is obvious that the cam projection P will pass beyond the projection P from the lever, so that the latter will return to its normal position, owing to the stress of its spring P. The punching operation is thus completed and the punch removed from the stock. The latter is then fed forward in any suitable way into such a position that the opening therein may receive an eyelet which is carried up from a suitable feed-chute E by means of the lower set H and inserted thereby into the said opening and forced against the upper set or anvil A the upward pressure of the lower set against the upper set completing the op eration of fastening an eyelet in the stock. The punch is shown as secured in a socket P by means of a set-screw P whereby it is rendered longitudinally adjustable; and the said socket itself is secured in a guideway at the end of the lever P by means of a screw P whereby lateral adjustment is provided for.

The reciprocating movement of the lower set is provided for in accordance with the present invention as follows: The said lower set is secured to the end of a reciprocating plunger H,longitudinally movable in a socket or bore formed in the extension A of the frame and connected, as by a link H, to a lever H pivotally supported upon a projection or stud H suitably secured to the side of the frame, the said lever being connected at its opposite end with an eccentric strap surrounding the disk E, which is eccentrically secured to the shaft B. Thus at each rotation of said eccentric the arm H is caused to swing upon its pivot and produce an up-anddown movement of the reciprocating rod H, carrying the set H to and from the upper set to insert and upset an eyelet.

In order that the eyelet may be picked up by the lower set as it rises, the feed-chute E is properly arranged to reciprocate, so that the end of said feed-chute will move forward over the lower set as the latter rises, thus presenting an eyelet thereto, and as the said eyelet is lifted above the surface of the chute the latter moves back to prevent the further upward movement of said lower set, this feature being substantially the same as in eyelet-machines as heretofore commonly constructed. The said eyelet-chute, however, is in accordance with the present invention arranged and caused to reciprocate in a novel manner, the said chute being provided with bearings E and E adapted to bear on rods E and E said rods being respectively supported in a pair of lugs E and a similar pair of lugs E formed on the side of the upward extension A of the frame. The said feed-chute is thus adapted to slide along the said rods, so that the end thereof will approach and recede from the lower set 11 to present eyelets thereto successively, as is necessary for the proper operation of the machine. To provide for such reciprocating movement, the said eyelet-chute is connected by a pitman E (which maybe, as shown, secured to the bearing E to a wrist-pin E upon the surface of the disk E, so that the rotation of said disk produces a reciprocating movement of the feed-chute.

From the foregoing description it will be seen that all the essential operations of the machine to prepare the stock and set the eyelets therein are produced by the rotation of a single disk secu red to the main shaft, there being no lateral movement of any of the op erative parts necessary, so that the operation of the machine is greatly simplified. By this arrangement, moreover, the throw or length of the movement of the lower set and the feed-chute may be readily adjusted, the lever H being herein shown as provided with an internally threaded socket H at the end thereof adapted to be screwed onto a threaded projection H from the eccentric-strap, which operates with the disk E, while the pitman E which is connected with the feed-chute, may be threaded, as indicated, and screwed into a socket E pivotally secured at E to the bearing E.

To render the operation of the machine entirely automatic, means may be provided for automatically feeding the stock so that after the punch has operated a suitable feed movement will take place to carry the stock forward until the opening made by the punch is brought between the sets, so that when they come together the eyelet will be inserted into said opening and upset by the action of the movable set in conjunction with the stationary set.

The feeding device, which is best shown in Figs. 4 and 4, consists of a pair of separable jaws C and D which are adapted, as will be shown, to swing together around a common axis and during their movement in one direction to grip the stock between them and carry it forward, means being also provided for separating the said jaws during their movement in the other direction, while the stock is held stationary by the lower set,

which, with an eyelet thereon, enters the hole at this time. The separation of the jaws also allows the stock to be lifted by the lower set to complete the operation of securing the eyelet in conjunction with the upper set.

The lever D is supported upon a lug A of the main frame and has a bearing upon a spindle C, said spindle extending through a suitable opening in said lug and also through a similar opening in the lug A so that it is capable of a longitudinal and an oscillating movement with relation thereto. The lever D is caused to swing on the axis of said rod by means of a cam projection D cooperating with a cam-surface (3 on a cam-wheel O, mounted on the main shaft 13 and rotatable therewith.

In order that the lever at the end of which is the jaw 0 may be capable of a vertical movement with relation to the lever D and at the same time incapable of oscillatory motion independently thereof, the said lever C is provided with a downward projection or pin 0 extending through a suitable opening in the leverD. The said lever C is secured, as bya set-screw C upon the rod (3, so that it will move vertically therewith and is adapted to be held in its normal position, or, in other words, pressed toward the lever D, so that the stock may be gripped between the jaws C and D by means of a spring 0 surrounding the rod C and bearing at one end against the lug A and at the opposite end against a collar G which is also secured to said rod. It is obvious, therefore, that by lifting the rod C the levers D and C will be separated, so that the stock gripped between the jaws and D will be released thereby. In order to produce this separation of the jaws, a lever C pivoted at C", is adapted to 006p erate with the lower end of the rod (1, so that when said lever is turned upon its pivot in the right direction it will operate to lift the rod C, carrying upward the lever (1 as is necessary.

To operate the lever C a projection C is connected thereto and extended into the path of a cam roll or projection 0 upon the camwheel 0, so that as the said wheel rotates the rod G will be lifted and the feed-jaws separated at each rotation thereof.

The cams C and C are so related to each other that the latter will operate to separate the jaws before the former operates to swing them back, and before the forward swing movement is accomplished the cam projection (3 has passed by the arm C and allowed the jaws to come together, so as to grip the stock and carry it forward, this feed movement taking place just after the punch rises from the surface of the stock, as shown in Fig. 4. The jaw D is provided with a knurled or roughened surface, and is slotted to permit the upward movement of the lower set, while the inner jaw is provided with a bent finger overlying a considerable portion of the surface of the lower jaw, so as to afford a firm grip. The anvi1-piece P, as shown in Fig. 4, is secured to the table T and extends upward through the slot T therein to support the stock during the punching operation.

It is desirable in feeding the stock after it has been punched to a proper position to receive the eyelet that the said stock should be guided in its movement, and for this purpose a gage for the said stock is preferably though not essentially provided, one of novel construction being herein shown and forming a part of the present invention, it being arranged in such a manner that it can be readily adjusted by the operator to vary the spreac of the eyelets or the distance thereof from the margin of the stock. Referring to Fig. 4 the said gage consists of a rounded stud G, projecting upward from the surface of the feed-table T, but movable with relation thereto, the said stud being adapted to be engaged by the edge of the stock and thus to determine the position thereof with relation to the punch and setting devices. To vary the relation of the stock to said devices, it is necessary to vary the positions of the gage, and to this end the said gageis mounted on an adjustinglcver G pivoted at G to the surface of the feedtable T, so that by swingin g the said lever on the said pivot the gage G is moved toward or from the punch and setting devices to vary the position of the stock with relation thereto.

In order that the adjusting-lever may be readily moved to varythe position of the gage and at the same time be retained in any of a number of predetermined positions, the said lever is provided at its outer end with a latch G, adapted to cooperate with a ratchet G, which may be, as shown, formed upon the edge of the table T, and the said latch is preferably held in engagement with the teeth of the ratchet by means of a spring G as shown in Fig. 2.

The latch is pivoted in lugs G secured to the lever G and provided with an operatinghandle, so that the attendant can move the said handle to withdraw the latch from the ratchet-surface G and also to swing the lever G2 upon itsfulcrum-pivot G.

As shown, the ratchet-teeth are so arranged that in order to move the gage away from its normal position it is necessary to manipulate the latch, while said manipulation is not necessary in order to restore the said gage. The ratcheting of the teeth is obviously not essential, it being obvious that any form of retarding device to prevent the movement of the lever in response to the pressure of the stock against the gage might be substituted for the ratchet-teeth shown. An adjustable stop G is provided, as shown, to determine the normal position of the lever G The eyelet-chute E, which consists, as has been described, of a reciprocating raceway, down which the eyelets move in a column to be successively presented to the end of the lower set H during the upward movement thereof, is provided with a reservoir or h0p per E adapted to be filled with eyelets in order to supply the said feed-chute during the operation of the machine. In accordance with the present invention the said reservoir or hopper is made complete in itself and provided with a closed bottom and detachably secured to the eyelet-chute, so that said reservoir and its contents may be readily removed without spilling the eyelets, if desired. For this purpose the said box is held in position upon the frame in which the raceway is formed by means of a stem E which passes through the opening in said frame and is provided with a collar E held in position by means of a thumb-screw E so that by unscrewing the said thumb-screw the said box may be removed. Within the said box the said stem E is provided with a head or enlargement 6 from which extend brushes 6, and the said stem is adapted to be oscillated to produce a movement of the brushes to agitate the contents of the box, so that the eyelets are di rected toward the opening a in the side of the box, through which they pass to the chute E. To produce said movement of the brushes, the collar E is connected by means of a link E to a projection E upon the main frame of the machine, so that during the forward and back movement of the chute the rod E is turned in its hearing as is desired.

As has been stated, the shaft 13 is provided with a hand-wheel B, and also with a pulley B whereby power may be applied to operate the machine, it being desirable in such cases, however, that the said power should be readily controlled by the operator. For this purpose a suitable clutch mechanism (not herein shown) is preferably provided and adapted to connect the said pulley B and the shaft B to said clutch, being controlled by a treadle cooperating with a reciprocating rod S, Fig. 4, having a suitable restoring-spring S It is not intended to limit the invention to the specific construction herein shown and described, since modifications may obviously be made without departing therefrom.
