Definitions

  • FREDERICK M FURBER, 0F REVERE, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEV JERSEY.
  • This invention relates to machines for ⁇ use in finishing boots and shoes and other articles and particularly to machines for applying blacking or finishing material, herein referred to generically as blacking, to the edges of heels or soles.
  • An object of the invention is to provide a machine by which the heel of a shoe can be blacked at the same speed as by hand or faste-r, with less liability of soiling other parts of the ⁇ shoe than the faces which it is intended to treat, and with greater assurance of thoroughly coating every portion of the surface that requires blacking.
  • An important feature of this invention consists in a machine for blacking heels hav ing provision for applying to the edge face of a heel enough blacking to coat it and for applying to the rand crease-that is, the crease between the upper and the sole or welt-a relatively greater quantity of blacking to insure the thorough coloring of all the surfaces in the crease and which will 'ireferably be enough to iiood the crease.
  • the blacking finds its way into the bottom of the crease and into the irregularities of the crease more surely and with less attention from the operator than when a brush or portion of a brush is employed which is supplied with a suitable quantity of blacking for coating the edge of the heel.
  • tion of blacking to the crease may be obtained by supplying to the crease or to the portion of the applying device acting at the crease a relatively greater quantity of blacking than to the edge of the heel or to like portions ofthe device for spreading the blacking on the edge face of the heel.
  • the blacking is applied to the heel by brushes, to the crease-blacking portions of which a greater quantity of material is supplied than to the edge-blacking portions.
  • This may be accomplished as here shown by arranging the brushes on vertical axes and supplying the blacking to the upper edge portion which enters the rand crease, while permitting the portion of blacking not used in the crease to work down by gravity to the lower edge-coating portion of the brush.
  • a feature of this invention consists'in providing means for automatically bending back the bristles at the edge of the brush.
  • This has the double advantage that the brush is kept in better shape so that it wears longer and that neater work is done.
  • the bending back of the bristles may be effected by a device with relation to which the brush travels in its rotary movement.
  • a plate arranged at the end face of the brush has an acting face which extends from a point within the periphery of the brush outwardly in a tangential line or in a direction oblique to the radius of the brush and wipes the bristles downwardly and outwardly as they pass under it.
  • This wiper has also a tendency to strip the blacking toward the ends of the bristles, keeping them clean and free from thickened or dried blacking which would otherwise accumulate at the edge of the brush.
  • means which is adapted to bend the bristles at the upper end of the brush, which are intended for applying blacking in the rand crease, downwardly into a position inclined toward the body of the brush.
  • the ends of the bristles are shaped to enter between the inclined upper and lower faces of the rand crease and force the blacking deeply into the crease.
  • the means herein shown for thus shaping the brush to enter the crease is the roll which transfers the blacking from the source of supply to the brush. This roll turns in contact with the creaseblacking bristles, wiping them downwardly and depositing upon them a quantity of blacking which they carry into the crease.
  • the blacking is supplied in sufficient quantities to flood the crease, being driven into the bottom of the crease by the shaped edge of the brush and the excess flowing down the face of the brush and the edge face of the heel over which it is wiped by the brush.
  • the end face of the brush is beveled, not only by the forming or shaping means described but in its initial formation to shape it for entering the rand crease.
  • This initial formation may be given to the brush by the direction in which the bristles are projected from the hub, but preferably it is obtained by cutting the bristles on a bevel, the upper bristles being made the shorter.
  • the bristles forming the crease-blacking portion of the brush may advantageously be much stiffer than the bristles that act on the edge of the heel. This enables them more certainly to force or drive the blacking into the crease. They are preferably formed upon a thin section of the brush, the body portion of which consists of soft bristles adapted to wipe the blacking over the edge face of the heel and leave a smooth coating thereon.
  • adjustable stops against which the turning movement of the shoe in both directions mair be limited are adjustable for shoes of different sizes and reduce materially the care rcquired of the operator in presenting the shoes so that he is able to work more rapidly.
  • Another important feature of this invention consists in provision for overcoming this difficulty and is herein shown as embodied in means for guiding the shoe with relation to the brush so that the bristles will not be flexed or bent backwardly enough when they reach the breast edge to cause them to spring or snap past the edge to an extent to spatter blacking.
  • the shoe-guiding means may advantageously be formed to permit the shoe to be pressed more closely against the brush when the portions'distant from the breast edge are being treated so that the bristles will wipe over it in the usual way for spreading coating material, but as the shoe is turned to present the por tion adjacent to and at the breast edge it is forced or guided outwardly from the center of the brush so that the backwardly bent bristles have opportunity to recover themselves or resulne substantially their normal straight position before they pass the breast edge. In this position they do not spring forward as they pass the edge and do not spatter blacking.
  • the shoe-guiding means for this purpose may advantageously be the same plate or device by which the upturned bristles are straightened as has been before described.
  • This device as herein shown comprises a stationary plate having an acting edge eccentric to the rotary brush and located with relation to the periphery of the brush to form a stop which permits the shoe to be pressed somewhat deeply into the brush when the body portion is being coated and to guide the shoe outwardly from the brush as the breast edge is approached so that the bristles may partially or completely recover their normal position when the edge is reached. Provision is made for adjustment of this guide and when, as here illustrated, a plurality of brushes are employed between which the heel is thrust for treating it at two or more points simultaneously the guides on opposed brushes may limit the extent to which the heel is thrust into the machine.
  • the extent to which the shoe is turned the operator may present the shoe without.
  • the exercise of that care and skill which would otherwise be rc ⁇ quired for he can merely thrust the heel backwardly upon the suitably adjusted tread rest until it is stopped by the guides and then swing or turn the toe end first to one side to the stop to black the heel to one breast edge and then swing it in the other direction until it engages the opposite stop for blacking the other side of the heel to the other breast edge.
  • rlhe guiding plates cause the shoe to be automatically moved outwardly from the brush center as the shoe is turned to move the breast edge toward the contact point with the brush.
  • Still another feature of construction is employed for this purpose of preventing' spattering and this consists in setting the bristles very close together and interlacing them more or less on the body portion of the brush, leaving no spaces between them as occurs when sepa ⁇ rate ⁇ bunches or tufts of bristles are set ⁇ at intervals in the hub so that the periphery of the brush is made up of distinct groups of bristles which are free to spring forwardly without encountering the adjacent group as they pass the breast edge of the heel.
  • the blacking which is taken from the reservoir by a drum having stirrers that keep the blacking constantly agitated, is delivered to the brushes by a rotary transferrer which turns in substantial contact with the drum at its front side and in the same direction as the drum and wipes downwardly across the upper end and edge of the brushes.
  • a rotary transferrer which turns in substantial contact with the drum at its front side and in the same direction as the drum and wipes downwardly across the upper end and edge of the brushes.
  • a further feature of this invention embodied in a modified construction consists in means for insuring the delivery of predetermined relative quantities of blacking to cach of the brushes and to each brush when adjusted into di iferent positions for treating large and small shoes.
  • This feature of the invention is shown as embodied in a distributer which may be substituted for the rotary transferrer or be used with said transferrer.
  • the distributer is herein shown as comprising a plate having its nar ⁇ row rear end arranged in scraping contact with the drum in the reservoir. rl ⁇ he front portion of the plate is provided with partitions or walls to divide the blacking as it comes from the drum and direct predetermined portions thereof toward each of the brushes.
  • rlhe distributer overlie the top faces of the brushes to deliver the blacking upon the crease section of the brush.
  • rlhe distributer is shown as having two channels for each brush. From one pair of channels the blacking is delivered upon the brushes when they are adjusted for large heels, as those of mens slices, and from the other pair of channels the blacking is delivered upon the brushes when they are adjusted closer together for small or womens shoe heels.
  • r1his channeled or partitioned distributer has the advantage that it insures to each brush its proper proportion of blacking whether or not the machine is set up level.

  • the machine comprises a reservoir 2 which is cylindrical in its general shape and has bearings for a shaft a carrying a drum 5 the periphery of which serves to lift blacking from the lower part of the reservoir to a transferrer 8.
  • the shaft has a pinion 10 driven from a worm 12 on a shaft let supported in bearings at the side of the machine and having fast and loose pulleys. Normally the belt will be retained on the fast pulley and the drum be constantly driven.
  • the drum has laterally projecting arms reaching nearly to the ends of the reservoir which sweep through the blacking near the bottom of the reservoir and keep it constantly stirred.
  • rlhe transferrer 8 is in the form of a roll driven, as indicated by the arrow thereon in Fig. 2, in the same direction as the drum 5 and is located substantially in contact with the drum so that the blacking is caused to collect or pile up in the angle between the peripheries of the two rolls.
  • the transferrer is driven from a worm 16 on the shaft 1, the inclination of this worm being opposed to that of the worm 12.
  • a scraper 17, which limits the amount of blacking carried by the transferrer and ⁇ catches any lumps that there may be, is positioned on the reservoir, as shown in Fig. 2, and can be adjusted by a screw 18.
  • the transferrer wipes down across the upper edge of the applying rolls 20, delivering its blacking upon the top thereof.
  • the rolls are arranged in' position to act simultaneously upon opposite sides of a heel thrust between them which can be turned to present the entire edge face to the action of the rolls.
  • the rolls comprise brushes, which are shown as tapered to conform to a usual shape of heel, and fast to vertical shafts 22 having worms 23 that engage opposite threaded portions of a shaft 25 which is driven by a pinion 26 from a worm 28 on the shaft 14.
  • Each roll shaft 22 has a collar 29 by which it is supported on the slotted forward extension or shelf 30 of the reservoir 2, as shown in Fig. 2.
  • Each of the two shafts 22 has a bearing in a block 32 which is guided in upright position on a horizontal slide rod 34 and a rod 35 which has oppositely inclined threads at 36 where it' passes through the bloe'ks and has a hand wheel 37 by which it can be turned to adjust the brush shafts from and toward each other for large or small shoes.
  • the slot-s in the shelf 30 permit this adjustment of the brush shafts 22.

  • the rest may also have a depending pin 43 to lit into a hole in the shelf 30 to prevent it from turning.
  • Stop pins 45 which may be covered with rubber, are arranged at opposite sides of the machine for limiting the eXtent to which a shoe is turned for presenting the entire side face up to but not beyond the breast edge.
  • the shelf 30 has a series of holes in which the stop pins may be positioned according to the size of the heels being treated and will assist the operator in terminating the swinging movement of the shoe before a point is reached at which the brushes would apply or spatter blacking upon the shank or breast of the shoe.
  • the brushes will comprise a main section m which may be of usual formation with long flexible bristles which will preferably be set as close together as practicable to brace one another and preventv them from snapping and spattering blacking as they pass the breast edge of the heel. These bristles may be mounted in a wooden hub of usual construction.
  • the brush comprises a thin section z5 adapted to act in the crease of the shoe.
  • This crease section will preferably include a wide metal hub or disk and short stilf bristles on its periphery adapted to resist the bending influence of the work upon them and to reach into and thoroughly coat the surfaces of the rand crease.
  • the acting edge of this section may be beveled as shown to adapt it to the shape of the crease.
  • the shorter bristles are at the upper edge and assist in preventing the relatively longer lower bristles from bending upwardly as they have a tendency to do after being used a little while.
  • the bristles will preferably be set less closely than in the main section of the brush to adapt them to carry more blacking into the crease.
  • the edge of the metal disks above the short bristles may, if desired, be arranged to engage the upper of the shoe to guide the shoe with relation to the brushes.
  • Additional guides 50 are arranged upon the top faces of the brushes and connected by the bar 52 which prevents them from turning, but permits them to slide toward and from one another, maintaining their proper relation to the brushes when the latter are adjusted.
  • These guides have acting edge faces for engaging the shoe which are formed eccentric to the brushes, as shown in plan view in Fig. 4. These eccentric edges uncover a maximum width of the bristles at the inner or adjacent portions of the two u brushes and permit it a decreasing extent of projection as the outer portion of the brush is approached or that portion which will act upon the shoe at and adjacent to the breast edge.
  • the eccentric formation of the guide also causes it to bend back automatically toward their horizontal position the bristles at the upper edge of the brush that have been bent upwardly by their engagement with the work. This keeps the brush in proper shape and also it prevents the daubing of the shoe upper which would be done by the bent-up bristles.
  • the tread rest may be provided, as shown in Fig.

  • a distributer in the Jform of a plate having its upper end in substantial contact with the drum 5 and itslower end overlying the brushes 20 is substituted for the transfer roll 8.
  • the distributer is supported by a block 62 having arms 63 sliding in a boss on the reservoir and a screwa connecting it with the boss for adjustment of the distributer horizontally whereby its relation to the drum and the quantity of blacking which it will take from the drum can be varied.
  • a scraper 65 adjustable by a screw 66 also is provided to vary the amount of blacking which the drum will carry to the distributer and t0 prevent any lumps from reaching the distributer.
  • the distributer is provided with partitions or dividing walls G8 arranged to divide the blacking as it comes from the drum and insure that a suitable proportion shall be directed to each brush even if the machine is not set up level.
  • the partitions also prevent the blacking thickening on the distributer in a way to form irregular channels as might occur if a plane surfaced distributer were employed.

FREDERICK M. FURBER, 0F REVERE, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEV JERSEY.
HEEL-BLACKING MACHINE,
moonen,
To all whom it may concer/n.'
Be it known that I, FREDERICK M. FUR- nnn, a citizen of the United States, residing at Revere, in the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in Heel-Blacking Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.
This invention relates to machines for `use in finishing boots and shoes and other articles and particularly to machines for applying blacking or finishing material, herein referred to generically as blacking, to the edges of heels or soles.
ltor convenience reference will be made herein to the work as the heel with the understanding that, except as obviously required by the context, the term is used in a broad sense to designate the heel, sole, or lother part of the shoe being worked upon.
An object of the invention is to provide a machine by which the heel of a shoe can be blacked at the same speed as by hand or faste-r, with less liability of soiling other parts of the `shoe than the faces which it is intended to treat, and with greater assurance of thoroughly coating every portion of the surface that requires blacking.
An important feature of this invention consists in a machine for blacking heels hav ing provision for applying to the edge face of a heel enough blacking to coat it and for applying to the rand crease-that is, the crease between the upper and the sole or welt-a relatively greater quantity of blacking to insure the thorough coloring of all the surfaces in the crease and which will 'ireferably be enough to iiood the crease. By flooding the crease the blacking finds its way into the bottom of the crease and into the irregularities of the crease more surely and with less attention from the operator than when a brush or portion of a brush is employed which is supplied with a suitable quantity of blacking for coating the edge of the heel. This relatively abundant applica Specication of Letters Patent.
Application filed August 7, 1908.

Serial No. 447,399.
tion of blacking to the crease may be obtained by supplying to the crease or to the portion of the applying device acting at the crease a relatively greater quantity of blacking than to the edge of the heel or to like portions ofthe device for spreading the blacking on the edge face of the heel.
In the embodiment of the invention herein shown the blacking is applied to the heel by brushes, to the crease-blacking portions of which a greater quantity of material is supplied than to the edge-blacking portions. This may be accomplished as here shown by arranging the brushes on vertical axes and supplying the blacking to the upper edge portion which enters the rand crease, while permitting the portion of blacking not used in the crease to work down by gravity to the lower edge-coating portion of the brush.
In the heel-blacking operation it is important to avoid smearing or daubing portions of the shoe which do not require to be blacked. I have discovered that by applying the blacking to the rand crease as above suggested the walls of the crease can be thoroughly blacked without getting much blacking on the upper at the side of the shoe. There is, however, a tendency for the bristles at the edge of the brush to spread out or bend upwardly against the upper and after a period of use these bristles assume an upwardly bent position in which they daub blacking upon the upper.
A feature of this invention consists'in providing means for automatically bending back the bristles at the edge of the brush. This has the double advantage that the brush is kept in better shape so that it wears longer and that neater work is done. The bending back of the bristles may be effected by a device with relation to which the brush travels in its rotary movement. As herein shown a plate arranged at the end face of the brush has an acting face which extends from a point within the periphery of the brush outwardly in a tangential line or in a direction oblique to the radius of the brush and wipes the bristles downwardly and outwardly as they pass under it. This wiper has also a tendency to strip the blacking toward the ends of the bristles, keeping them clean and free from thickened or dried blacking which would otherwise accumulate at the edge of the brush.
In accordance with a further feature of the invention means is provided which is adapted to bend the bristles at the upper end of the brush, which are intended for applying blacking in the rand crease, downwardly into a position inclined toward the body of the brush. By this means the ends of the bristles are shaped to enter between the inclined upper and lower faces of the rand crease and force the blacking deeply into the crease. The means herein shown for thus shaping the brush to enter the crease is the roll which transfers the blacking from the source of supply to the brush. This roll turns in contact with the creaseblacking bristles, wiping them downwardly and depositing upon them a quantity of blacking which they carry into the crease.
The blacking is supplied in sufficient quantities to flood the crease, being driven into the bottom of the crease by the shaped edge of the brush and the excess flowing down the face of the brush and the edge face of the heel over which it is wiped by the brush. Preferably and as herein shown, the end face of the brush is beveled, not only by the forming or shaping means described but in its initial formation to shape it for entering the rand crease. This initial formation may be given to the brush by the direction in which the bristles are projected from the hub, but preferably it is obtained by cutting the bristles on a bevel, the upper bristles being made the shorter. The bristles forming the crease-blacking portion of the brush may advantageously be much stiffer than the bristles that act on the edge of the heel. This enables them more certainly to force or drive the blacking into the crease. They are preferably formed upon a thin section of the brush, the body portion of which consists of soft bristles adapted to wipe the blacking over the edge face of the heel and leave a smooth coating thereon.
In blacking the heel at and adjacent to the edge of the breast care must be exercised to avoid running past the edge and depositv ing blacking on the breast face of the heel and upon the shank, which in many shops is not to be blacked. To assist the operator in presenting or turning the shoe with relation to the brushes to bring the side of the heel into position to be blacked without soiling the breast and shank I have provided, in accordance with another feature of this invention, adjustable stops against which the turning movement of the shoe in both directions mair be limited. These :stops are adjustable for shoes of different sizes and reduce materially the care rcquired of the operator in presenting the shoes so that he is able to work more rapidly. One of the difficulties encountered in blacking heels is that the bristles spring or snap forwardly as they pass the edge of the breast and spatter blacking upon the shank and sole.
Another important feature of this invention consists in provision for overcoming this difficulty and is herein shown as embodied in means for guiding the shoe with relation to the brush so that the bristles will not be flexed or bent backwardly enough when they reach the breast edge to cause them to spring or snap past the edge to an extent to spatter blacking. The shoe-guiding means may advantageously be formed to permit the shoe to be pressed more closely against the brush when the portions'distant from the breast edge are being treated so that the bristles will wipe over it in the usual way for spreading coating material, but as the shoe is turned to present the por tion adjacent to and at the breast edge it is forced or guided outwardly from the center of the brush so that the backwardly bent bristles have opportunity to recover themselves or resulne substantially their normal straight position before they pass the breast edge. In this position they do not spring forward as they pass the edge and do not spatter blacking. The shoe-guiding means for this purpose may advantageously be the same plate or device by which the upturned bristles are straightened as has been before described. This device as herein shown comprises a stationary plate having an acting edge eccentric to the rotary brush and located with relation to the periphery of the brush to form a stop which permits the shoe to be pressed somewhat deeply into the brush when the body portion is being coated and to guide the shoe outwardly from the brush as the breast edge is approached so that the bristles may partially or completely recover their normal position when the edge is reached. Provision is made for adjustment of this guide and when, as here illustrated, a plurality of brushes are employed between which the heel is thrust for treating it at two or more points simultaneously the guides on opposed brushes may limit the extent to which the heel is thrust into the machine. By thus limiting the extent to which the heel enters the machine and also limit-ing, by the adjustable stops, the extent to which the shoe is turned the operator may present the shoe without. the exercise of that care and skill which would otherwise be rc` quired for he can merely thrust the heel backwardly upon the suitably adjusted tread rest until it is stopped by the guides and then swing or turn the toe end first to one side to the stop to black the heel to one breast edge and then swing it in the other direction until it engages the opposite stop for blacking the other side of the heel to the other breast edge. rlhe guiding plates cause the shoe to be automatically moved outwardly from the brush center as the shoe is turned to move the breast edge toward the contact point with the brush. Still another feature of construction is employed for this purpose of preventing' spattering and this consists in setting the bristles very close together and interlacing them more or less on the body portion of the brush, leaving no spaces between them as occurs when sepa` rate `bunches or tufts of bristles are set `at intervals in the hub so that the periphery of the brush is made up of distinct groups of bristles which are free to spring forwardly without encountering the adjacent group as they pass the breast edge of the heel. No danger arises of spattering blacking by the portion of the brush that acts in the rand crease and the relatively short and stiffer bristles of this portieri of the brush may advantageously be set less close together so that they will carry a greater quantity of blacking into the rand crease. Provision is made, in an angularly adjustable heel tread rest, for supporting the shoe with the rand crease in parallel relation to the creaseblacking section of the brush.
1n the preferred embodiment of the invention the blacking, which is taken from the reservoir by a drum having stirrers that keep the blacking constantly agitated, is delivered to the brushes by a rotary transferrer which turns in substantial contact with the drum at its front side and in the same direction as the drum and wipes downwardly across the upper end and edge of the brushes. rlhis delivering mechanism, which has the advantage of keeping the blacking in constant motion on moving parts of the mechanism so that it has no opportunity to settle or thicken andV thereby impede its delivery, is an important feature of this invention.
A further feature of this invention embodied in a modified construction consists in means for insuring the delivery of predetermined relative quantities of blacking to cach of the brushes and to each brush when adjusted into di iferent positions for treating large and small shoes. This feature of the invention is shown as embodied in a distributer which may be substituted for the rotary transferrer or be used with said transferrer. The distributer is herein shown as comprising a plate having its nar` row rear end arranged in scraping contact with the drum in the reservoir. rl`he front portion of the plate is provided with partitions or walls to divide the blacking as it comes from the drum and direct predetermined portions thereof toward each of the brushes. The forward portions of the distributer overlie the top faces of the brushes to deliver the blacking upon the crease section of the brush. rlhe distributer is shown as having two channels for each brush. From one pair of channels the blacking is delivered upon the brushes when they are adjusted for large heels, as those of mens slices, and from the other pair of channels the blacking is delivered upon the brushes when they are adjusted closer together for small or womens shoe heels. r1his channeled or partitioned distributer has the advantage that it insures to each brush its proper proportion of blacking whether or not the machine is set up level.
These and other features of this invention, including certain details of construction and combinations of parts, will appear in connection with the following description of the machine in which l have embodied the invention for the purpose of explanation and will then be pointed out in the claims.
Figure 1 is a front elevation of the machine; Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a'plan. Fig. 4 is also a plan showing the action of the guides. Fig. 5 is a detail of the shoe rest. Figs. 6, 7, 8, 9 and 10 show modifications.
The machine comprises a reservoir 2 which is cylindrical in its general shape and has bearings for a shaft a carrying a drum 5 the periphery of which serves to lift blacking from the lower part of the reservoir to a transferrer 8. The shaft has a pinion 10 driven from a worm 12 on a shaft let supported in bearings at the side of the machine and having fast and loose pulleys. Normally the belt will be retained on the fast pulley and the drum be constantly driven. The drum has laterally projecting arms reaching nearly to the ends of the reservoir which sweep through the blacking near the bottom of the reservoir and keep it constantly stirred.
rlhe transferrer 8 is in the form of a roll driven, as indicated by the arrow thereon in Fig. 2, in the same direction as the drum 5 and is located substantially in contact with the drum so that the blacking is caused to collect or pile up in the angle between the peripheries of the two rolls. The transferrer is driven from a worm 16 on the shaft 1, the inclination of this worm being opposed to that of the worm 12. A scraper 17, which limits the amount of blacking carried by the transferrer and `catches any lumps that there may be, is positioned on the reservoir, as shown in Fig. 2, and can be adjusted by a screw 18. The transferrer wipes down across the upper edge of the applying rolls 20, delivering its blacking upon the top thereof. These rolls are arranged in' position to act simultaneously upon opposite sides of a heel thrust between them which can be turned to present the entire edge face to the action of the rolls. The rolls comprise brushes, which are shown as tapered to conform to a usual shape of heel, and fast to vertical shafts 22 having worms 23 that engage opposite threaded portions of a shaft 25 which is driven by a pinion 26 from a worm 28 on the shaft 14. Each roll shaft 22 has a collar 29 by which it is supported on the slotted forward extension or shelf 30 of the reservoir 2, as shown in Fig. 2. Each of the two shafts 22 has a bearing in a block 32 which is guided in upright position on a horizontal slide rod 34 and a rod 35 which has oppositely inclined threads at 36 where it' passes through the bloe'ks and has a hand wheel 37 by which it can be turned to adjust the brush shafts from and toward each other for large or small shoes. The slot-s in the shelf 30 permit this adjustment of the brush shafts 22. A table or heel tread rest 40, in the form of a three-edged plate having its faces adjacent to the brushes concaved to conform approximately to the peripheries of the brushes, has a depending stem that fits into the tubular upper end of an adjusting screw 42 having a hand wheel on its lower end, as indicated in Fig. 2. The rest may also have a depending pin 43 to lit into a hole in the shelf 30 to prevent it from turning. Stop pins 45, which may be covered with rubber, are arranged at opposite sides of the machine for limiting the eXtent to which a shoe is turned for presenting the entire side face up to but not beyond the breast edge. The shelf 30 has a series of holes in which the stop pins may be positioned according to the size of the heels being treated and will assist the operator in terminating the swinging movement of the shoe before a point is reached at which the brushes would apply or spatter blacking upon the shank or breast of the shoe. The rest will be adjusted vertically for heels of different heights and will support the shoe in such relation to the brush that the upper edge portion of the brushes will enter and black the rand crease between the upper and the top face of the heel seat end of the sole. Preferably the brushes will comprise a main section m which may be of usual formation with long flexible bristles which will preferably be set as close together as practicable to brace one another and preventv them from snapping and spattering blacking as they pass the breast edge of the heel. These bristles may be mounted in a wooden hub of usual construction. In addition the brush comprises a thin section z5 adapted to act in the crease of the shoe. This crease section will preferably include a wide metal hub or disk and short stilf bristles on its periphery adapted to resist the bending influence of the work upon them and to reach into and thoroughly coat the surfaces of the rand crease. The acting edge of this section may be beveled as shown to adapt it to the shape of the crease. The shorter bristles are at the upper edge and assist in preventing the relatively longer lower bristles from bending upwardly as they have a tendency to do after being used a little while. The bristles will preferably be set less closely than in the main section of the brush to adapt them to carry more blacking into the crease.
The edge of the metal disks above the short bristles may, if desired, be arranged to engage the upper of the shoe to guide the shoe with relation to the brushes. Additional guides 50 are arranged upon the top faces of the brushes and connected by the bar 52 which prevents them from turning, but permits them to slide toward and from one another, maintaining their proper relation to the brushes when the latter are adjusted. These guides have acting edge faces for engaging the shoe which are formed eccentric to the brushes, as shown in plan view in Fig. 4. These eccentric edges uncover a maximum width of the bristles at the inner or adjacent portions of the two u brushes and permit it a decreasing extent of projection as the outer portion of the brush is approached or that portion which will act upon the shoe at and adjacent to the breast edge. This formation of the guides that determines the relation of the work to the bristles insures that the bristles shall be bent back by the work less as they approach the heel breast edge. This reduces the tendency of the bristles to spatter or throw blacking as they snap past the edge of the breast. The eccentric formation of the guide also causes it to bend back automatically toward their horizontal position the bristles at the upper edge of the brush that have been bent upwardly by their engagement with the work. This keeps the brush in proper shape and also it prevents the daubing of the shoe upper which would be done by the bent-up bristles. The tread rest may be provided, as shown in Fig. 5, with a superposed angularly adjustable shoe supporting plate 39 pivoted to the rest 40 and adjustable by a screw 4l to support pitched heels with the rand crease parallel to the crease-blacking section of the brush. The screw 4l will take the place of the pin 43 that is shown in Fig. 1.
In the use of the machine a shoe is presented with the tread face of the heel on the rest 4() and pushed back between the brushes, which with the guides 50 carried by them are relatively adjusted to permit the heel to be thrust into position for both sides to be treated at the same time. The guides 50 stop or may limit the backward movement of the heel. The shoe is then turned toward one side and then toward the other to swing the entire edge surface of the heel into contact with the brushes to be coated with blacking by them. The stops limit the turning movement so that the blacking is not smeared upon the shank of the shoe or upon the breast face. As the shoe is turned in contact with one guide or the other along its side toward the breast edge said guide, by its eccentric formation, forces the heel farther away from the axis of the brush so that the bristles are permitted to unbend or partially unbend before they pass the breast edge. The bristles which may be upbent by the work are automatically straightened by the eccentric guides with each rotation of the brushes. These bristles are also further straightened by the engagement of the transferring roll 8 with them. This roll wipes down from the top of the brush and turns the bristles down even below their normal position. It will be observed that the transferrer applies the blacking upon the top or top edge of the brush from which position it flows down by gravity to the lower portions. This gives a maximum of blacking for those bristles which are to apply it in the rand crease. By the arrangement shown, by which the blacking is applied in large quantitiesupon this upper portion of the brush, the bristles entering the crease flood blacking into the crease so that it finds its way into all the cracks and depressions. The rubbing engagement of the transferrer with the bristles at the edge of the brush keeps these bristles clean and prevents blacking from drying and caking at this part of the brush as it would otherwise do. The machine will preferably be maintained in motion constantly so that the brushes are loaded with blacking ready for coating a heel at any time. Scrapers remove surplus blacking from the brushes and return it to an inclined portion of the shelf 30 from which it flows back into the reservoir. rI`hese Scrapers may be adjustably attached to the shoe-guiding plates, as shown in Figs. 3 and el, by binding screws, and will be maintained with said plates in constant relation to the brushes in the relative adjustment of the brushes. The arms l5 keep the blacking in the entire reservoir con stantly stirred and prevent the wax, which is in suspension in the blacking solution, from settling as it has a tendency to do quite rapidly.
In the modified construction shown in Figs. 6, 7, and 8 a distributer in the Jform of a plate having its upper end in substantial contact with the drum 5 and itslower end overlying the brushes 20 is substituted for the transfer roll 8. The distributer is supported by a block 62 having arms 63 sliding in a boss on the reservoir and a screwa connecting it with the boss for adjustment of the distributer horizontally whereby its relation to the drum and the quantity of blacking which it will take from the drum can be varied. A scraper 65 adjustable by a screw 66 also is provided to vary the amount of blacking which the drum will carry to the distributer and t0 prevent any lumps from reaching the distributer. The distributer is provided with partitions or dividing walls G8 arranged to divide the blacking as it comes from the drum and insure that a suitable proportion shall be directed to each brush even if the machine is not set up level. The partitions also prevent the blacking thickening on the distributer in a way to form irregular channels as might occur if a plane surfaced distributer were employed. The partitions are shown as arranged to provide two runs for each brush. From the inner ones blacking will be directed upon the brushes when the latter are adjusted for small heels and from the outer ones the blacking will fall upon the brushes when they are positioned for large heels of mens shoes. The shaft 35 is provided in thismodification with cams 70 (shown in Fig. 8) instead of the screw threads 36 of Fig. l coperating with the brush carrying blocks 32 to adjust the brushes and a spring 72 holds the blocks 32 against the cams. In this construction the drum is driven from an internal gear and a pinion, as shown in Fig. 7. rI`he transferring roll 8 and the distributer 60 are more than substitutes the one for the other for each has a distinctive function in addition to their common function of carrying the blacking and in Fig. 9 I have shown an arrangement in which the roll and the partitioned distributer are combined to secure the distinctive function of each while they co operate in delivering the blacking. The partitioned distributer insures the delivery of predetermined proportional quantities of blacking to the portions of the transferrer which cooperate with the different brushes in their adjusted positions and the roll carries these portions of blacking directly to the brushes. The roll also serves its characteristic purpose of shaping the edge of the brush and wiping or stripping the bris tles that work in the rand crease.
I have illustrated in Figs. 9 and l0 a modified construction of the sliding rod 52 (Fig. 4;) which connects and holds the guides 50 from rotating. In the modification two rods 52 have their adjacent ends pivoted on a vertical post (Fig. l0) and their other ends slide in lugs on the guides 50, thus enabling the brushes to be adjusted toward or from each other. By this construction a relative adjustment between the guides 50 and their respective brushes can be effected, since as the brushes are moved toward or from each other, the rods 52 will cause the guides 50 to turn on their respective brushes, thus adjusting the guides into the proper positions for guiding a different size or style of heel.
In the following claims reference is made to positions of parts and to directions of movement of elements which are to be understood as terms of designation and not of limitation, as it is obvious that the relative positions and the relative directions of movement are important rather than absolute and positive directions.
Having explained the nature of this invention and described a preferred construction embodying the same, I claim as new and desire to secure by Letters Patent of the United States:
1. A machine of the class described having, in combination, means for blacking a heel having provision for applying a relatively greater amount of blacking material to the rand crease than to the edge of the heel.
