Specification of Letters Patent.

Patented Sept. '7, 1909.

Application filed August 12, 1908. Serial No. 448,195.

To all whom it may concern:

Be it known that I, WILLIAM F. LAUTEN- SCHLAGER, a citizen .of the United States, residing at Cincinnati, in the county of Hamilton. and State of Ohio, have invented certain new and useful Improvements in Eyeleting- Machines, of which thefollowing is a specification.

' Eyeleting machines for setting eyelets automatically are in practice operated at a high rate of speed, the eyelets bein usually set at the rate of two hundred and fifty to four hundred per minute. The range of work in the usual shoe factory where these machines are em loyed is also great, both in regard to the size of eyelets employed and the distance apart at which the eyelets are set in the stock. In order to accommodate the necessary range of work, and to provide the necessary speed of operation for given eyelets or spacing-distances between eyelets,

it has been a general practice heretofore, in

factories employing machines of this character, to install machines of different sizes for different ranges of work or sizes of eyelets, these machines being usually installed in sets of three. The work or stock, passing through the various departments of the factory for having successive operations imparted to it, reaches the eyeleting department in lots, the several lots being intended to receive'eyelets' of various sizes, also spaced different distances apart. For economical operation it has been the practice heretofore to provide each operator with a set of eyeleting machines above mentioned, usually three, so that entire lots could be completed without the necessity of breaking or dividing the lots, the consequence being that the operator was obliged to do part of the eyeleting on one machine and other parts on the other machines of the set, the space in the shop occupied by each operator. bein the sum of the space occupied by the severa ma-- chines of; his set of machines. s

It is the object of my invention to provide an eyeleting machine capable of setting eyelets of the various sizes usuall employed in eyeleting work, and capable o a w1de range of feeding movement for accommodating the various requirements of spacing-distance between'eyelets, while permitting very rapid operation for allsizes and spacing-distances between eyelets.

It is the object of my invention further to increase the speed of operation of machines The invention will be readily understood from the followin description and claims, and from the drawings, in which latter:

Figure 1 is a front elevation of my 1111'- proved device. Fig. 2 is a vertical section of the same on the line ww of Fig. 1. Fig. 3 is a vertical cross-section of the same on a line corresponding to the line yy of Fig. 2. Fig. 4 is a detail in edge elevat1on showing the means for positioning the bell. crank lever; and, Fig. 5 1s a detail in section on the line z-z of Fig. 2 showing the adjustment in the rocking-member.

'1-represents the frame of the machine, in

which. a cam-shaft 2 is journaled in bearings 3.

4 is a head, supporting a punch-ram 5. Sidewise reciprocation is imparted to the head, as by having bearings 6 thereon slide sidewardly on a rod 7 secured to the frame and a rod 8, secured to the head, sliding sidewardly in bearings 9 of the frame, the sidewise reciprocation bein imparted by means to be presently escrlbed. The unch-ram has up and down reciprocation imparted to it by a crank-pin 10 journaled in a block 11 operating in a slide-way 12 in the punch-ram, the crank-pin being on a rook-shaft 13 which has a segment-gear 14 thereon.

15 is a lever pivoted on screws 16 in the frame and having a cam-housing 1 7 in which av cam 18 on the cam-shaft operates for imparting sidewise oscillation to said lever, the upper end of said lever having a segment-gear 19 meshing with the segmentgear 14 for imparting rocking mot1on to said rock-shaft 13.

20 is a lower setting-die adapted to coop- I accomplish these objects by novel mechanerate with the upper setting die 21 on the punch-ram, the latter having a setting-face and also acting as a punch in manner to be hereinafter described. These setting dies, are removable for substituting other settingdies of various sizes for accommodating eyelets of difi'erent sizes. The lower setting-die is on a ram 22 which has u and down reciprocation in bearings 23 1n the frame, these reciprocations being imparted by a crank-pin 24 on the cam-shaft journalefd in 'a slide-block 25in a guide-way 26 on the lower setting-ram.

There is an eyelet-receiving finger 27 adapted to receive eyelets froman eyeletchute 28 which 'has movement imparted thereto by means of an angle-lever 29 articulated therewith and operated by the cam 30 on thecam-shaftrotatmg in a cam-housing 31 on said angle-lever. The e elet-finger is normally ressed upward y by a spring 32 but is a apted to be retracted by the punch-die when the eyelet is being set. Cross feed is imparted to the punch-head. The punching, operation takes place at one ofthe limits of movement of said punchhead, and the settingoperation takes place at the other of its limits of movement. My improved device provides means whereby these limits of movement may be separated small or great distances for accommodating allclasses of work and sizes of eyelets ordinarily used. The distance between the said limits ofmovement represents the spacing distance between eyelets.

The punch is adapted to descend ,on the anvil 33for performlng the punching operation, which takes place at the right hand limit of movement of said punch-ram illustrated in F ig. 1, the punch descending for performing the punching o eration and then moving to the left into ine with the lower setting-die, carrying the stock with it, at which point the eyelet, heretofore received upon the eyelet-finger, is set into the stock,

whereupon the settlng dies again separate, the punch being returned to its punching positlon for repeating the operation.

In order to obtain a wide range of sidewise reciprocation of the punch-head I have provided a cam-housing 34 which has a guideway 35 therein preferably received about and guided by the cam-shaft, and isprovided with an extension 36 having a guideway 37 therein, in which latter a guide-block 38, shown as on one of the screws 16, is received. A cam 39 is on the cam-shaft and operates on the u per contact-face 40 and the lower contact-lime 41- of the cam-housing for moving said cam-housing radially 0 said cam-shaft, the said guide-ways maintaining said movement in a given direction, the movement being exemplified as a vertical movement. Arockin member 42 is journaled about the rock-shatt 13. It comprises a sleeve 43 and a finger 44, having a hub 45 encompassing the sleeve, the finger and sleeve being relatively adjustable by set-screws 46. There is a slot 47 in the finger in which there is a slideblock 48, a pm 49 in the head being journaled in the slide-block, the construction translating the rocking movement of the rocking-member into sidewise reciprocating movement of the head. The rocking-member is provided with an arm 50 in which there is an arc-slot 51 receiving a block 52 arranged to have sliding movement therein. 53 is a connecting-rod which is pivoted at 54 to said block and at 55 to the upward extension on said cam-housing. The are of the slot 51 is described from the pivotal axis of the connecting-rod 53 with the camhousing 34, whereby I obtain an arc of short radius compared with the distance between the rotary axis of the cam-shaft and the pivot 54. The said are is exemplified as described from said pivotal axis when said setting-dies are in 0 position or setting position, in other wor s, at the setting limits of movement of said punch-ram, and when said cam-housing is at its upward limit of necting-rod 53, is to the rocking axis of said rocking-member, the greater will be the rocking movement imparted to the rocking. Y

member by the cam 39 through the radial .moving cam-housing and the connectin -rod articulated tothe latter and to said roc ingmember.

56 is a bell-crank lever pivoted at 57 .to the frame. 'A link 58' is articulated with the arm 59 of said lever at 60 and with said connecting rod at 61. Means are provided for adjusting the range of movement of the bell-crank lever. Thus it is received in a slot 62, the walls 63 of which are provided with perforations 64 for receiving pins 65 66 against which the arm 67- of the bellcrank lever is arranged to strike for controlling'the pivotal position of said bell-crank lever and thereby controlling the range of cross-reciprocation of the punch. In the exemplification, the higher the arm 67 is p0 sitioned the smaller will be the cross-reciprocation of the punch, andthe lower the osition of said arm is-the greater will be t is cross-reci rocation. The positioning effect of the bel -crank lever uponthe connectingrod is produced from a pivotal'point which always moves in a iven direction radially of the cam-shaft an u on an are having a short radius compare with the distance from the rotary axis of the cam-shaft to. the arc-slot, the resultant of which is an increased distance of cross-reciprocation of the punch-head, by which I am enabled to provide adjustments of lengths of cross-reciprocation accomplishing spacing-distances between eyelets throughout a range which will encompass the spacing-distances employed in ordinary practice and which'rangeheretofore had to be accomplished by a plurality of machines as hereinbefore stated.

The eyelets in the quarters of a shoe are usually set at different distances apart, the eyelets at the bases of the quarters being closer together than those at the tops of the quarters. In setting the eyelets those of one spacing on the quarter are first set and the 'machine then-changed by swinging the bellcrank lever while running for setting the eyelets of the other spacing on that quarter. The arm 67 is normally at its upward limit, being held in place by a spring 68.

69 is a rock-shaft which has a projection 7 0 thereon between which and the bell-crank opposlng movements of the setting dies are also accomplished at a definite point with" relation to the cross-reciprocation of the punch-head. Thus the arrow 75 represents the direction of rotation of they cam-shaft.

The cam-housing 34 always moves in the same plane radially of the cam-shaft, the approach of the setting-dies taking place at one of the limits of cross-reciprocation of the punch-head effected by the movement of said cant-housing. The cam-housing always moving in the same direction, will always have its contact-faces engagedby the. hi h point of the cam 39 at the same point in t e rotation of the cam throughout all adjustments for lengths of cross-reciprocationof the punch-head, so that a definite time-relation is maintained between the rocking of the rock-shaft 13 and ofthe rockin -member 42 in all such adjustments,where%y-I am enabled to leave a material part of the factor of safety between the timing of said two motions out of consideration, and to correspondingly increase the speed of the machine.

The connecting-rod 53 may be adjustable and left hand threads at its respective ends for being received in similarly threaded sockets in said end-pieces, jam-nuts. 79 securing the parts of the connecting-rod in rigid relation.
