EYELETING-MACHINE.

Specification of Letters Patent.

Application filed. June 24, 1904. Serial No. 214,023.

improved means for detachably fastening the setting devices to the plungers or hoiders on which they are mounted.

Another object of the invention is to provide mechanism for imparting a powerful stroke to the plunger which carries one of the setting devices, and also to actuate the raceway by said mechanism.

Other novel features of my invention will be hereinafter pointed ont.

The present invention is shown as ernhodied in an eyelet setting machine of that type which comprises a stationary upper e \eletsetting device, a movable lower eye itsetting device, and a racewav adapted to he shifted into and out of the path ol movement of the lower setting device. for delivering eyelets thereto. Machines of this type are usualljv provided with detachable setting devices, so that eyelets'of ditl'ercnt forni and size may he operated upon in the. saine machine, and the usual method of fastening the setting device to the plunger or holder on which it is mounted is to provide said plunger or holder with a socket to receive the shank of the setting device, a set screw projecting through the wall of the socket and engaging the shankof the setting device to retain it. in place. This method of iasteniner a setting device to its plunger is objectionable in that the set screw which bears against the side. of the shank ofthe setting device causes said device to incline more or less in one direction, therebythrowing it out of axial alinenient with its plunger or holder and also. ont 'of alinement with the"ccpcrating setting device. Conseuently when the upper and lower setting evices are brought together, the eyclet being operated upon will he damaged. To overcome this objectionnlile feature l have nrnvided a. fastening (le- ,sleeve being vice which will bear evenly upon all sides of the shank of thc'setting device to be retained in place, thereby insuring axial alinement of the upper and lower setting devices s0 that the eyelets will not be damaged during the setting operation. r

Referring to the drawings, Figure 1 is a side elevation, partly in section, of a foot power eyeleting machine embodying 'the features of my invention; Fig. .2 is a sectional view on the line x`x of Fig. 1 and shows a novel means for adjusting the raceway laterally; Fig. 3 is a vertical sectional view of the lower cyclist-setting device and shows the means for detachably fastening it .to the plunger on which it is mounted; Fig-4 is a. sectional view on the line w-w of Fig. 3; Fig'. 5 is a detail vicw, partly in section, and shows the spindle of the lower setting device in engagement with the lowerinost eyelet on tho raceway, preparatory to removing it therefrom; Fig. .6 is a det-ail view similar to Fig. 5 and shows the relative positions of the lower setting device and raccway just after -the. eyelet has been removed; Fig. 7 is a view similar to Figs. 5 and 6,- and shows the lower setting device cooperating with the upper device for ,setting an eyelet in a piece of stock; Fig. 8 is a det-ail showing the opera.- tion of the mechanism for restoring the raceway to its normal position; Fig. 9 is a sectional view on the line y-y of Fig. l and shows the mechanism for rotating the brush or agitator mounted int-hc hopper; and Fig. 10 is a sectional view on the line z--z of Fig. 1, and shows the friction device for retaining the raceway in its retracted position.

In the drawings, 2 designates a table or other support to which the frame 4 of the machine is attached. The upper eyelet-setfting device 6 is carried by a holder 8 mounted in the frame, and the lower eyelet-sctting device 10 is carried by a plunger 12 mounted in a guidcway 14 formed in the lower part of the frame of the machine. The mechanism for imparting a reciprocating movementto the plunger 12 is connected. to the lower end thereof and will be hereinafter fully described.

In Fig. 3 of the drawings is shown the preferred form of fastening device, 4which coinprises a s litsleeve 16 mounted in a socket 18 forme in the end of lunger 12, said rovided wit a head 20 of {ruste-conical orm which is of greater diame- ,ngi-....naMmW- ter than' the part of the sleeve that projects into the socket 18', said head resting upon the end plunger'12. The plunger 12 has a screw-threaded portion near its u er end on which. is threaded a nut- 22 provi ed with a tapered bore or inclined portion -that surirounds and cooperates with therusto-conical 1 hea to produce" a'ccntraction of thegsleeve for clamping the shank of the setting device wheneveil the nut 22 is screwed downwardly.

The shank of the setting device is reduced in diameter so as to form a shoulder which rests upon .the head 20, and as said head rests upon the end of the plunger the setting device will always be maintained in the same elevated position relatively to the plunger. ,Mounted in a longitudinal ore of the lower setting devioe is a'spindle 24 which normally pi'oiects above the acting face thereofpthe said spins dle being adapted to engage and remove the lowerinost eyelet on the raceway during the .upward movement of the setting device. A

Spring 26 coniined the socket 18 and bearing against the end of the spindle holds said spindle in its elevated position, but permits it to yield whenthe two setting devices.

are brought together. lt will thus be seen that by turning the nut 2,2 in the desired direction the split sleeve 16 will-beeithei; contracted or allowed to expand to clamp or release the setting device, and as the pressure on all sides of the shank of the setting device is uniform it is impossible for said device to be thrown out of axial alinement with its supporting plunger. The holder 8 is pro- .vided with t e same kind of fastening means for retaining the upper setting device 6 in ing adjustab lace. A

For operating uponstock of different thickiiesses it is necessary for one oi' the setting devices to have a vertical adjustment, and in this embodiment of the invention I have shown the u per eyelet-setting device as be- Ile towards and from the lower device. This is accomplished by providing the holder 8 with a screw-threaded portion 9 which engages a corresponding screw-thread-- -ed perdon formed in the frame, so that by rotating said holder its elevated position will be varied and the setting device carried thereby will be brought nearer to or farther away from the lower setting device. A set -screw 11 is inountedin the frame and bears against the side of said holder for retaining it 'shown in Fig. 1.

.the plunger 12 is elevated as already to the frame at '31 and connected withA a treadle or other device by means of a rod 32.

YIntermediate the actuating lever and the 'plunger 12 is a system of links arranged to forni three toggle joints which are particularly e'ective for shifting the raceway, for moving the plunger, and for applying maxlinuin pressure thereto when an cyelet is being clenched ni the stock. The three toggles are supplied by a link 34 pivoted to the plunger 12, a link 35 pivoted to one end of the actuating lever 30, and a link 42 which has a fixed pivot43. The links 34,36 and 42 are pivoted to each other by a pin which constitutes a knuckle common to the three toggles (sce Fig. 1), During the initial movement of the actuating lever 30 (in the direction of the arrow in Fig. 5), the first-acting toggle, consisting o links 36 and 42, serves to roject the link 34 into axial alinenient with the plunger (see Fig. 6), so that the clenching pressure, subsequently transmitted through the link 34, shall be applied to the plunger in the most eil'ective direction. This initial movement of the actuating lever also elevates the plunger until. the spindle 24 en' gages an eyelet (see F ig. 5). Progressing further, the movement of the actuating lever 30 tends to force the link 34 out of alinement with the 1 lunger and away from the link 42; but saidink 42 resists-this tendency and, in

effect, serves as a retract-ing force, applied at the knuckle o a second toggle composed of links 34 and 36, to cause said toggle to straighten out, with the result that a rapidly augmented pressure is exerted upon theplunger as it nears the limit ofits movement to clench an eyelet. A raceway 43 is shifted through the agency of an arm 35 on the link 34, and this arm35 and the link 42 constitute 1 the third toggle above referred to. The

'movement of the actuating lever gradually increases the anglo of the toggle35, 42 (see Figs. 5, 6 and 7), andthercby causes an engaging face 38 and a roller 40 on the arm 35 to perform their proper oflices as herein' after explained.

' he raceway 48 is sup orted by levers 44 and 46 which are pivotecl) to the frame at 45 and 47. The lever 46 has rollers 50 and 52 arranged to be engaged by the roller and engaging face 38 on the arm 35 so as to roduce a rocking movement of said lever w 'ch shall shift the raceway. i

The normal inactive positions of the raceway, plun er .and actuating'mechanism are -shown in ig. 1, wherein, it will be seen, the end of the raceway projects over the u r extremity of the lower setting device. lllin described, the spindle '24 will enter the barrel of an eyelet and detain it when the raceway is retreated. During the movement of the actuating lever30, as the anglev of .the toggle composed of arm 35 and link 42 is increased,

the roller 40 on arrn 35 engages roller 50 on lever 46, and rocks said lever 1n the direction of the arrow in Fig. 6. This shifts the feed end of the raceway out of the path of the lower setting device. The relative posit-ions of the plunger and raceway at different stages in the machines operation may be observed in Figs. 1 to 8 inclusive.

Throughout the above-desc ribed operation, the actuating lever has been depressed by the treadle rod 32. When the eyelet has been clenched the rod 32 is released and `a spring 54, attached at one end to the frame and at the other end to the rod 3,2, retract-s the actuat- 24 of t ie ower setting device.

ing lever thereby.` causing the various parts to resume their normal inactive positions. During this retraction of the actuating lever 30 the engaging face 3S of the lever cont-acts with the roller 52 on lever 46 and de resses said roller, rocking the lever 46 and shifting the raceway 'so that its feed end is again roljected into thepath of the spindle I The position of the feed end of the raceway relative to the setting devices, may be varied by adjusting the stop 56, mounted in the frame, which limits the movement ofthe lever 46 b v contacting with a buiier 57 carried by said lever. The retracting movementof the actuating lever 30 is limited by a sto 58 carried by the lover, and a. boiler 59 on t e frame.

A friction device comprising a springpressed plunger 44 (see Fig. 10) is carried h v lever -14 and hears against a part of the frame of the machine to prevent the raceway from being accidentally shifted.

The raceway herein shown can be readily removed from thc machine when it is desired to substitute for it a raceway of diiierent size Alower end an arm 64 which is hiurcated to engage a rod 66 mounted in an arm projecting from the frame, (see Fig. 9) whereby an oscillating movement of said spindle and brush is el'ected whenever the raceway is shifted. The raccway is provided with hifurcated feet 48 which straddlc collared studs 68, 68 carried by levers 44 and 46, said raceway being held in position by tlu-.clamp ing plate 70 which bears upon one side. of the. feet to force them against nuts 72 threaded on the studs, as shown in Fig. 2. When it is desired to move the raceway laterally t: bring the end thereof -into exact alim-ment with the setting devices, the mits 72 and the clamping plate 70 are moved in the desimt direction on threistuds and as the.` feet of the raceway are clamped between said nuts and Having fully described my invention, what I claim as new and desire to secure by Letters lPatent of the United States, isz- 1.
