EDGE-INKING MACHINE.

Specification of Letters Patent.

Patented Jan. 10, 1911.

To all whom it may concern:

Be it known that I, ANDREW W. REDI'N, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Edge-Inking Machines, of which the following is a specification. j y

This invention relates to machines for applying ink or blacking to the edges of shoe soles and heels during the process of manufacturing shoes.

One of the objects of the invention is to produce means for rapidly and evenly applying ink to the edges of a sole, including the top of the portion of the sole which projects beyond the vamp and the beveled 'surfaces of the sole.

Another object is to prevent the ink from being applied to the vamp.

A further object is to provide means for stirring the supply of ink to prevent settling and to keep the-ink of uniform consistency.

A further object is to provide means for regulating the flow of ink to the ink-apply in@ device.

The invention also relates to the other features of improvement herein set forth.

In the accompanying drawings, Figure. 1 is a side elevation, with parts in section, of a machine embodying the features. of my. in-

vention. Fig. 2 is a front elevation of the machine. Fig. 3 is a'section on line 3 of Fig. 1. Fig. 1 is a section online 4 t of Fig. 1. Fig. 5 is a sectional view through one of the valves, the view being taken in the lane of the axis ofthe valve. Figs. 6 and? the latter in open and closed position, respectively. Fig. 8 is a detail yperspective view of the brush used in inking the sole. Fig. 9 is a sectional view of said brush, and illustrates the manner of applying the shoe thereto. Fig. 1() is a rear side elevation of said brush. Figs. 11 and 12 are sections on lines 11 and 12, respectively, of Fig. 9.

The embodiment herein shown of my invention comprises a framework which may consist of the base 1, said base having lugs 2 thereon by means of which the machine m'ay be secured to a bench or other suitable support. Rising from the base 1 is a bracket 3 upon which is supported a reservoir 4 for the ink or dye. Said reservoir, in the form are detail views of the valve, showing l lower end of the reservoir 4 is a boss 5 having an outlet passage 6 therein and adapted 4 to be inserted into a slot 7 in the upper end of the bracket 3. The reservoir is removably secured to the bracket by means of a lock nut 8 turned upon the screw-threaded lower end of the boss 5 and arranged to clamp the reservoir to the bracket. The lock nut 8 is provided with an operating arm 9 by means of which it may be given a partial rotation to release or clamp the reservoir. From the reservoir 4: the ink flows to an oscillatory or swinging brush which is carried by a lever 10 pivoted intermediate its ends upon a stud 11 having a screw-thread connection with the base or frame of the machine. The upper end of the lever 10 is bifurcated, as shown in Figs. 1 and 2 at 12, the bifurcation receiving a slidable block 13 which is carried by a crank pin 111 upon the forward end of the shaft 15 carried by the base 1. On the shaft 15 is a tight pulley 16 and a loose pulley 17 to receive a drive belt 18. It will be seen that as the shaft 15 is rotated, the lever 10-will be oscillated upon its pivot 11.

The brush for applying the ink to the sole comprises, in this instance, a back 19 (Figs. 8 and 9) suitably curved so that the tufts of bristles 2O shall be adapted to engage properly the edge of a sole and the top of the portion of the sole projecting beyond the vamp. The back 19 is 'attached by means of screws 21 to a block 22 having a shallow recess 23 therein, said recess communicating with the concave face of the back 19 by means of ducts 24. The block 22 is rigidly secured to a block 25 havin-g a shank 26 adapted to be inserted into a socket 27 in the lower en d of the lever 10, said shank being removably clamped in said socket by means of a .set screw 28.

For applying ink to the heel, I use a brush (not shown) having a surface conforming to the shape of the edge of the heel, the heelnking brush being interchangeable with the sole brush.

A valve 29 (Fig. 5) located intermediate the reservoir and the brush comprises a plug 30 having a screw-threaded stem 31, which stem is turned into a screw-threaded opening in the stud 11. A port 30u is formed of the stud 11 by means of an operating arm 33. On the forward end of the valve .plug 30 Vis 'a.finger'piece-"34 The valve casing 35 is mounted to swing upon the valve plug 30, being held in proper relation Vto said Y valve plug by means of a nut 36. Extending through the casing 35 is a p assage-37. On the lower end of the valve casing 35 1s a nipple 33' which communicates with the chambered brush back by means of a tube 39 attached to the brush. The tube 39 has a slip connection with the nipple 3S so that Vthe brush may be readily removed and another form of brush substituted. A pin 40 fixed in the lever 10 and having a forked forward end which embraces'the ni-pple 3S causes the valve casing 35 to oscillate with said lever and the brush.

To the lower end of the boss 5 on the reservoir 4 is fixed a valve 41 comprising a valve casing 42 and an oscillatory valve plug 43. rl`he valves 29 and 41 are flexibly connected together by means of a tube 44 of rubber or the like, the ends of said tube being slipped over the nipples 45 and 46 upon said valves. rIhe oscillatoryv valve plug 43 has an operating arm 47 fixed thereto. To the rear end of the arm 47 is attached a spring 48 which tends to rock the valve plug 43 in the direction to close the valve. The arm 47 may be manually operated in any suitable way toopen the valve, as, for example, by means of a flexible connection49 extending to a treadle (not shown). y,

lVhen the opening 30a through` the valve v plug 30 extends horizontally, as shown in Fig. 5, the oscillations of the valve casing 35 do not bring the passage 37 into register with said opening, and the valve 29 therefore is closed even though the shaft 15 may beA rotating. Vhen the valve plug 30 is turnedeither to the right or the left by means of the finger piece 34, the oscillations of the valve casing 35 will bring the passage 37 therein into register with the opening 30a, the extent to which said openings register, depending upon the extent to which the` valve plug 30 is turned from the horizontal by the operator. It will be seen from Figs. I 6 and 7 that when the lever-10 swings in one f direction, the valve 29 will open, and that when the lever swings in the opposite direction the valve will close. VVThe relative` movement between the valve casing 29 and the valve plug 30 prevents the ink from clogging 1n said valve.

To indicate the extent to which the valve i 29 is opened, a graduated plate 50 may be provided,- sa-id plate being fixed to the frame i of the machine, the valve plug 30 being provided with a pointer 51 arranged to swing across the face of said graduated plate.

i Inorder to prevent the application of the ink to the vamp, I provide a guard plate 52 which is secured to the machine frame. Said guard late'lies in front of the forward portion o the brush.

In order to agitate the contents of the reservoir 4 and thereby keep the ink of uniform consistency, I provide a )erforated dasher disk 53 fixed to the end of a stem 54 which extends through a central opening 55 in the cap 56 of the reservoir. To the lower side of the disk 53 is fixed a central pin 57 arranged to enter the outlet opening 6 to prevent clogging ofsaid opening and to positively force ink therethrough. The dasher disk and the pin 57 are reciprocated by means comprising, in this instance, a rod 58 secured to the stem 54 by means of a screw 59, the rod 5S being vertically reciprocable in a guide 60 fixed to the machine frame. The lower end of the rod 58 is connected rto a wrist pin 61 upon a sprocket wheel 62 by means of a connecting rod 63. The sprocket wheel 62 is mounted upon a shaft 64 and receives a chain 65 extending over a sprocket wheel 66 fixed upon the shaft 15. then the shaft 15 is rotated, the rod 58 is reciprocated to operate the disk 53 and the pin 57.

In practice, it is desirable to place in the reservoir 4 a quantity of the solution sufficient for a days work, and to remove the reservoir at night in order that it may be thoroughly cleaned and a fresh supply of ink placed therein when beginning `the following days work. The reservoir may be removed by turning the lock nut 8 to release the lower end of the reservoir, removing the screw 59, and disconnecting the rubber tube 44 from the nipple 46. The cap 56 may have a slip connection with the upper end of the reservoir so that it may be readily removed and replaced in replenishing the supply of ink.

In operation, the operator opens the valve 29 by turning the valve plug 30 into, say, the position said plug is shown to occupy in Fig. 6. When he is ready to present a shoe to the machine, the operator opens the valve 41, as by means of the treadle hereinbefore alluded to. The shaft 15 being rotated, the ink will flow to the swinging brush. The operator now takes a shoe, preferably with a last a therein, and presents the edge of the sole Z) to the brush, as indicated in Figs. 1

and 9. The gua-rdv plate 52 not only keeps the ink olf the vamp c, but also serves as a guide as the shoe is moved by the operator, the said guardlying in the angle between the vamp and the sole. The back of the sole brush is curved so as to present the ends of the tufts of bristles squarely to the sole. As the operator moves the edge of the sole along under the rapidly swinging brush, t-he latter spreads the ink evenly upon the vertical edge of the sole and the top of the project* ing portion thereof, as well as upon any beveled surfaces that may be formed on the edge portion of the sole. For inlring the heel, a brush having a face conforming to the shape of the heel-edge is substituted for the brush 19 20, the heel brush having yan attaching stem and a tube similar to the stem 26 and the tube 39 of the sole brush.

I would have it understood that I desire not to be limited to the details of construction herein shown and described, for various modifications will occur to persons skilled in the art.
