SHOE-POLISHING MACHINERY.

Application filed. January .22, 1917.

To all whom it may concern Be it known that 1, PETER J. RUMPF, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Shoe-Polishing Machinery, of which the following is a full, clear, concise, and exact description.

This invention relates to improvements in shoe machinery and more particularly to shoe polishing machinery.

In the manufacture of boots and shoes as now commonly carried on, it is customary to apply to the soles thereof, a suitable polish commonly known as bottom polish which is generally in the form of a specially prepared wax and which is designed to fill up the crevices and interstices in the leather, to render the same more or less impervious to water, and to impart a polish thereto. Heretofore in actual practice it has been common to apply the polish to the polishing element by hand, the polish in the form of a cake, being pressed against the polishing element, which is generally in the form of a rotary brush, so that a portion of the same is taken up by said brush; the cake of polish being then laid aside and the sole of a shoe held against the brush to thereby treat and polish the same. This procedure is slow and cumbersome and also very wasteful of the material used, by reason of the fact that when a cake of the same becomes too short to permit of the same being conveniently handled, it is thrown away and a new cake substituted.

The present invention aims to overcome these various disadvantages, and has for its object the provision of a machine wherein the polish is fed into contact with the brushing element automatically; another object being to provide means whereby the speed of the automatic feeding mechanism may be varied as desired to increase or decrease the feeding operation.

A further object of the invention is to provide a machine of the type described with a novel form of holder, adapted to receive the polish and to cooperate with the feeding mechanism, whereby said polish is fed upwardly into contact with the polishing element.

Other objects will be apparent from the fOllOWiIlg description, taken in connection with the accompanying drawings, in which is shown the preferred embodiment of my Specification of Letters Patent.

invent-ion. It is to be understood however, that the disclosure is for purposes of illustration only, the same being susceptible of many changes and modifications, and the right is herein reserved to make such changes as fairly fall within the scope of the appended claims.

Figure 1 is a side elevation of the ma-- chine, the brushing element and main shaft being shown partly broken away.

Fig. 2 is a front elevation thereof.

Fig. 3 is a detailed sectional view of one of the guides.

Fig. 1 is an enlarged fragmentary view partly in section, of a portion of the ma" chine;

Fig. 5 is an enlarged side elevation of the eccentric mechanism; and

Fig. 6 is a transverse sectional view thereof.

Fig. 7 is a sectional detail on line 77, Fig. 3.

In the drawings, the base of the machine is illustrated at 10 and is shown provided with suitable flanges 11 adapted to receive bolts or other fastening means (not shown), whereby said base may be secured to a suitable support 12, shown in dotted lines in Figs. 1 and 2. Pivotally mounted at 13 on the base 10, by means of suitable lugs 1-1, preferably integral therewith, is a wax or polish holder 15. At 16 is pivoted a suitable lock adapted to swing into and out of engagement with the flange 17 of the holder 15 to fasten the same in its closed position on the base 10, as shown in Fig. 2. This looking mechanism is shown provided with a suitable set screw 18 which may be screwed down into contact with the flange 17 to retain the wax holder against accidental displacement. The holder 15 may be cast iiitegral if desired, but is shown in the drawings as provided with an inner cylindrical sleeve 15, within which the cake of wax" or polish is placed.

Depending from the base 10 is a suitable frame 19 adapted to support the operating mechanism of the machine. This frame 19 comprises depending side members 20, a transverse member 21, hangers 22, and a suitable bracket 23, all of which may be cast integral .if desired, they being shown in the drawings however, as formed separately and secured together by suitable fastening means. Mounted on the hangers 22 is a counter shaft 21, on one end of which is shown a pulley adapted to be driven by means of a suitable belt 26 from the main shaft 27. Mounted transversely of the side members 20 of the frame 19, are a plurality of shafts 28 and 29, the latter of which is shown provided with a gear wheel 30 which meshes with the worm 31 formed on the counter shaft 2i. Mounted on one end of the shaft 29 is an eccentric 32 provided with suitable pawl 33 adapted for engagement with a ratchet wheel 3-l mounted on the corresponding end of the shaft 28. Intermediate the ends of the shaft 28 is shown a pinion 35 meshing with a rack 36 which is shown mounted in suitable guides 37 and 38. The rack 36 as shown, extends through the base 10 in such a manner as to lie substantially in the center of the wax holder 15, said rack 36 being provided at its upper end with a wax supporting base 39, adapted to reciprocate within the cylindrical sleeve 15 of the holder 15 in a manner hereinafter described. The base 39 may be integral with said rack but is shown in the drawings as secured thereto by a set screw 40. The bracket 23 is bolted to the side members 20 of the frame 19 and depends therefrom. Positioned in the lower end of said bracket is a suitable cup n adapted to cushion the rack 36 when the same is released as hereinafter set forth. This cup may be provided with felt or other suitable cushioning material.

The pawl 33 working in conjunction with the eccentric 32 and the ratchet wheel 3i preferably passes through a suitable guide T2, said guide being provided with an up turned flange *3 and secured in any suitable manner to the frame 19 adjacent said ratchet wheel 34:. A spring 5%, connected to the upturned flange as of the guide 12 at one end and to the pawl 33 at the other end, provides means whereby said pawl is held in positive engagement with the teeth of the ratchet wheel 3i.

Pivotally mounted directly beneath the base 10 between lugs is a lever &6, one end of which is connected to the pawl 33 by means of a suitable connecting member 4L7, shown in the drawings in the form of a wire. A suitable set screw as is shown screw-threaded in the base 10, and is adapt ed to bear on the other end of said lever &6, whereby the pawl 33 may be raised out of engagement with the ratchet wheel 3% against the action of the spring i4, when the pressure of said set screw 48 is increased. The spring 44 returns the pawl 33 into engagement with the ratchet wheel 3& when the pressure of said screw 48 is released. Pivoted at 49 to one of the side members 20 of the frame 19, is shown a dog 50 which is adapted to engage the teeth of the ratchet wheel 34 to prevent any reverse movement of said ratchet wheel while the pawl 33 is being carried back by the eccentric 32 prior to its forward movement. A spring 51 keeps the dog 50 in engagement with the teeth of the wheel Suitable adjustable means is shown extending upwardly through the base 10 from one end of the dog 50, whereby said dog may be drawn out of engagement with the ratchet wheel 33, for purposes hereinafter set forth.

In Figs. 5 and 6, the eccentric 32 is shown more in detail. From these figures it will be noted that the throw of the eccentric may be varied, whereby the feeding upward of the rack 36 by virtue of the cooperation between the pawl 33, ratchet wheel 34c, and pinion 35, may be increased or decreased as desired. As shown, the eccentric 32 is provided with a slotted member 53, swaged or otherwise secured directly on the end of the transverse shaft 29 and adapted to revolve therewith. Secured to the outer circumference of the member 53, is a substantially semi-circular ring 5%, shown slotted at 55 for the reception of a suitable adjusting screw 56, which lies within the slot in said member 53, and which is held against reciprocatory movements therein by means of the collars 57 which engage opposite sides of the ring 5% as shown. The screw 56 engages a suitable studded block 58 also mounted within the slot of the member said block 58 being adapted to be reciprocated therein by the turning of the screw 56 to thereby increase or decrease the eccentric position of the same. A nut 59 is mounted on the outer end of the stud, which is preferably integral with the block 58, for the purpose of clamping the various parts in any desired relation. Pivotally mounted on said stud intermediate said block and the nut 59, is the pawl 33. It will be noted from this structure that the step by step movement imparted to the shaft 28 by means of the pawl and ratchet mechanism, may be varied without reducing the speed of the shaft 29. r

In the operation of the machine, the pawl 33 and the dog 50 are drawn out of engage ment with the ratchet wheel 34, thus permit-- ting the rack 36 to descend until the rear end thereof engages the cup i1. W hen the rack is in this position, the supporting base 39 lies at the bottom of the wax holder 15, and in contact with the base 10. This permits the wax holder 15 after the same has been released by swinging the lock 16 out of engagement with the flange 17 thereof, to be swung back on its pivot 13 to the dotted line position as shown in Fig. 2. A cake of wax or other polishing *material, is then inserted into the cylindrical sleeve 15 of said holder 15, preferably from the rear thereof, said holder being then swung back into its operative position on the base 10 and locked against accidental displacement. It will be noted from the foregoing that the wax,

which is illustrated at 60, will rest upon the supporting base 39, mounted on the upper end of the rack 36, when the holder has been returned to its operative position as flllJOVC described. The inner cylindrical sleeve 15 of the holder 15 is preferably of such height that the cake of wax or other polish, when placed within the same will project a short distance above the upper end thereof, and into contact with the rotary brush (51 which is shown mounted on the main shaft 27, substantially as shown in Figs. 1 and The manner in which the step by step upward movement of the rack 36 is accomplished, whereby the wax is kept in con-tact with the brush (31, will now be described.

Assuming that the parts are in the position shown in Figs. 1 and 2, motion is imparted to the pulley from the main shaft 2'? by means of the belt 26. This revolves the counter shaft Ql and also the shaft 29 by virtue of the gear wheel 30 and the worm 31. The pulley 25 is preferably made many times larger in circumference than the shaft 2? in order that the counter shaft 2% will be driven at a reduced rate of speed. The rotary motion of the shaft 29 drives the eccentric 32, the pawl 33 of which revolves the shaft 28 in the direction of the arrow in Fig. l, the dog 50 cooperating therewith to prevent any reverse rotation of said shaft as heretofore pointed out. This step by step movement imparted to the shaft 28 is transmitted by means of the pinion 35 to the rack 36, thus moving said rack upward. The cake of wax or other polishing material, being mounted on the base 39, is likewise fed up 'ard by the movement of the rack 36 and accordingly is kept in contact with the rotary brushing element 61. Should it be desired to stop the feeding operation at any time, the pawl 33 may be raised out of contact with the ratchet wheel 34:, as heretofore pointed out, the dog acting to hold the rack in whatever position it is in at the time the withdrawal of the pawl 33 is effected. lVith the device as illustrated, it will be noted that substantially the entire cake of wax or other polishing material is utilized, thus dispensing with the waste which exists in the methods now in common use, as heretofore pointed out.

It is obvious that various changes may be made in the detailed construction of the machine, without departing from the spirit of the invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. A machine of the class described, comprising a table, a vertically-disposed wax holder normally resting on said table, a rod extending upwardly into said holder through an opening in said table and being provided with a supporting plate at its upper end, means coac-ting with the lower end of said rod for feeding said plate upwardly, and means whereby said holder may be tilted back out of engagement with said table to thereby render access to said plate unobstrueted.

2. A device of the class described, comprising a table, an upright holder resting thereon, arack extending through said table and into said holder, means to impart a step by step movement to said rack, and means whereby said holder may be tilted back away from said rack to receive a cake of wax, said wax being brought into position on the upper end of said rack when said holder is swung back into operative position.

3. A machine of the type described, comprising a base, a holder thereon, a frame depending therefrom, and a rack mounted in suitable guides and extending into said holder, a counter shaft supported from said frame, a plurality of shafts mounted transversely of said frame, an eccentric mounted on the end of one of said transverse shafts, a ratchet wheel mounted on the corresponding end of the other of said shafts, a pawl connected to said eccentric and engaging the teeth of said ratchet wheel, a pinion mounted on the same shaft with said ratchet wheel and meshing with said rack, and means for transmitting motion from said counter shaft to said eccentric whereby said pinion moves said rack upward within said holder by virtue of the cooperation between said pawl and said ratchet wheel.
