EYELETlNG-MACHINE.

. SPECIFICATION forming part of Letters Patent No, 644,797, dated March 6, 1900.

Applicationfiled November 4,1895. Renewed May 27, 1899. Serial No. 718,534. (No model.)

T0 at whom, it may concern.-

Be it known that I, LOENDER O. EMERSON, of North Grafton, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Eyeleting-Machines, of which the following is a specification.

In certain styles of laced boots and shoes it is customary to set over a number of the eye lets at the lower ends of the rows which are fastened in the upper, giving the rows an outward curved or spread appearance.

It is the object of this invention to provide means in an eyeleting-machine whereby the setting over of these eyelets in the desired manner is insured.

In furtherance of the above-stated object I arrange a movable guide or gage for the work and make provision for moving the same at the proper time and in the proper manner to dispose the work for receiving the set-over eyelets.

A mechanism embodying the invention is described hereinafter and illustrated in the accompanying drawings, which form part of this specification.

Figure 1 shows a side elevation of a portion of an eyeleting-machine to which the invention is applied. Fig. 2 shows a front elevation. Fig. 3 shows a top plan view of the work-supporting table and parts connected therewith. Fig. 4 shows a side elevation of a portion of the machine from the same side as Fig. 1, certain parts being removed. Fig. 5 shows a section on line 5 5 of Fig. 4. Fig. 6 shows a section on line 6 6 of Fig. 5.

The general construction of the eyeletingmachine is not changed from that ordinarily employed in machines of this character, and it will not therefore be necessary to enter into a detailed description of the same. An enumeration of a number of the principal parts will suffice.

The letter a designates the work-supporting bed or table, which is slotted, as at a, to accommodate the punching and upsetting devices.

b designates the perforating-die, and c and d designate the usual carriers for the upsettin g-dies the carrier d being affixed to a vertical rod (1 which is reciprocated vertically in fixed guides d d on the frame of the ma= chine.

On the upper side of the table a is arranged a guide or gage e, formed to bear on the edge to the slot 0, and thata change in the position of the gage will effect a change in the distance from the edge of the upper to the place of insertion of the eyelet. Therefore by moving the gage laterally with relation to the coacting point of the sets and the edge of the upper receiving the eyelets any desired distance between the edge of the upper and the place of insertion of the eyelets can be had. Hence by supplying suitable means to move the gage the object primarily stated can be ac- 7 5 complished. The means here shown are as follows: A vertical stud or shaft f is j ournaled in a bearing in a block f, aiiixed to the frame of the machine. To the upper end of said shaft is affixed a crank-arm f containing a slot f Said arm is connected by a link f with a slide g, which is movable on the under side of the table a and is engaged therewith by means of plates g 9 movable in guides in the upper side of the table and connected through slots 8 5 in the table with the slide g by screws 9 g. The gage e is secured to the plate g by the screw 9 and is therefore movable with the slide g. It will be seen, therefore, that a rotation of the shaft f will, through the crank- 0 arm f link f and slide 9, move the gage e toward or from the point where the settingdies coact. Means are provided for rotating said shaft step by step in either direction by the power of the machine, and consequently automatically, said means represented by a a ratchet-plate h, affixed to the shaft f and provided with two series of ratchet-teeth h h, a carrier t', which is movable toward and from the shaft f and carries two pawls i iiadapted, [00

It will be ap- 6o respectively, to engage the ratchet-teeth h 7L2, and means for moving the pawl-carrier toward and from the shaft f.

The means for actuating the pawl-carrier during the movement of the setting devices to set an eyelet is represented by an arm j, pivoted at j to a fixed stud 7' and bearing loosely on the pawl-carrier t', said arm being arranged so that a lug or projection (Z on the setting-die carrier d will strike a rollj on the lower end of the arm at each descent of the (lie-carrier, and thus move the pawl-carrier toward the shaft 1. The pawl-carrier is moved away from the shaftf by a spring It follows, therefore, that the pawl-carrier is moved toward the shaft f by each downward movement of the setting-(lie carrier cl and is moved away from said shaft during each upward movement of the said die-carrier.

Provision is made for making the pawl 2" operative and the pawl i at the same time inoperative, and vice versa, said pawls and the accompanying ratchet-teeth being so arranged. that when one pawl is operative it is caused by the described movements of the pawl-carrier to rotate the shaft f step by step in one direction, Whereas when the other pawl is operative it will rotate the said shaft step by step in the opposite direction, said pawl and the pawl-carrier controlling suitable actuating mechanism for the ratchet-plate. To this end I pivot at k to a downwardly-projecting ear on the pawl-carrier 'i a lever 70, under the control of the operator, it having at opposite sides of its pivot two pins 7t projecting upwardly through holes in the pawlcarrier and having their upper ends beveled, as shown in Fig. 6. The lever 70 is adapted to be moved on its pivot by the operator, one of its ends being extended to form a handle. When the handle end is elevated, the pin k is raised, as shown in Figs. 4 and 6. Its bev eled end is caused to move the pawl t" outwardly, making it inoperative, as shown in Fig. 5, the pin 70 being at the same time depressed, so that it releases the pawl i and permits its engagement with the ratchet-teeth 72 by means of the spring 2'. It will be seen, therefore, that the operator can cause a stepby-step movement of the shaft f and gage c in either direction by suitably adjusting the lever 70.

The operation of the machine with reference to my improved attachment is or may be as follows: The gage a being adjusted at the maximum distance from the eyelet-setting dies and the lever 70 adjusted to cause the step-by-step movement of the gage toward the setting-dies, the machine is set in operation as usual, the first eyelet being set with the gage in its maximum-distance adjustment. When the setting-die carrier d descends after setting the first eyelet, the lug cl moves the pawl-carrier, thus moving the gage one step nearer the setting-dies through the described intermediate mechanism. hen the setting-die carrier rises, the next eyelet is set and the pawl-carrier is retracted by its spring, and so on, thegage being moved in-' wardly one step after the setting of each eyelet, the number of steps being determined by the number of ratchet-teeth. After the in ward step-by-step movement of the gage has been completed the machine may continue to operate with the gage at the minimum distance from the setting-dies. After one row of eyelets has been set in this way the setting of the row in the next piece may commence at the upper end, the gage remaining at its minimum-distance adjustment, the setting continuing until the point of spreading is reached, when the operator by moving the lever 7t causes the gage to recede step by step from the setting-dies, thus causing the lower eyelets to be set at grad ually-increasing distances from the edge. The slot f in the crank-armf enables the maxim urn distance of the gage from the setting-dies to be increased or diminished to vary the spreading of the eyelets, the link f being connected with the said crank-arm by a stud f which is adjustable in said slot. Hence by adjusting the said stud the operator may increase or diminish the spread of the eyelets.

I do not limit myself to the described details of mechanism for giving the gage a stepby-step movement to vary the distance of successive eyelets from the edge of the piece in which they are inserted and may use any suitable means for giving the gage such movement without departing from the spirit of my invention.
