manner.

To all whom it may concern Be it known that I, FRnDnnrcKl /l. Fun- BER, a citizen of the United States, residing at Revere, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Heel-Blacking Machines, of which the following description, in connection with the accompanying drawings, is a specification, likereference characters on the drawings indicating likeparts in the several figures. 1

This invention relates to machines for applying blacking or other coloring matter to boots and shoes.

The invention is herein shown and described as embodied in a machine for apply ing blaclring to edges of heels, but many of its features may be used for applying this or similar coloring matter to other parts of boots and shoes, as for example to the edges of soles.

Certain features of the invention will also be found of value in the performance of other operations upon boots and shoes, as for instance cleaning or polishing the sun faces of heels or soles.

A very important feature of the invention consists in an arrangement of shoe-engaging members whichare adapted for oscillation about the parts of the shoe being treated and also adapted to be rotated while in engagement therewith so as to apply the blacking to said parts, or otherwise act thereon in a veryei i'ective manner, and with great rapidity. In connection with this feature of the invention the shoe may be conveniently supported upon a rest in position for action thereon by the said members, and means be provided for adjusting the position of the shoe relatively to the members in such manner that in case, for example, a heel is being treated the distance traveled by the members in their oscillations about the heel may be the same as the length of the heel, or if desired may be less than its length, according to such adjustment. This enables the operator to control the extent of the area to which the blacking is applied for heels of different sizes, and is an important feature of my invention.

In the embodiment selected for illustrati on the shoe rest is located between the shoe engaging members, and a fork to embrace the rear or counter portion of the shoe cooperates with the rest in positioning the OE REVERE, IlliASSl-lCI-IUSETTS, 'ASSIGHOR TO UNITED SHOE hIACI-IINERY COMPANY, OF PA TERSQN,

Specification of Letters Patent. Patented Dec. 15 1914 Application filed Gctober 31, 1916. Serial No. 589,940.

shoe heel relatively to said members. The fork and rest are preferably connected and so arranged as to slide in unison in a direction substantially parallel with the path of said members in moving along the sides of the heel, and an adjustable stop is provided to variably limit the extent of rearward movement offithe rest and fork. lVhen the stop is adjusted for any given size of heel, the shoe and its rest and fork are moved to the rear, and will automatically be arrested at the desired point to lo cate the heel in the proper position relatively to the members that apply the blacking thereto, so that the limits of the forward movement of said members will be at, or slightly to the rear of, the heel breast.

Preferably the shoe-engaging members, which are herein shown in the form of brushes are supported in carriers which are arranged for swinging movements about centers located on opposite sides of the shoe support, and the carriers are also arranged to slide along guides which are supported for movement with the carriers about the same centers. Preferably also the brushes are held'by yielding means in contact with a suitable cam device, and when a shoe is positioned'on' the shoe support the yielding means holds them against the heel so that when 'reciprocated along the guides the brushes will be caused to move in opposite directions about the heel and to follow its contour irrespective of irregularities or differences in size. Means are also provided to impart rotation to the brushes simultaneously with the described oscillating move ments, whereby the blacking will be applied thoroughly to every portion of the heel over which the brushes are caused to travel. in the construction herein selected for illustration, rotation is imparted to each of the brushes through a shaft which has connection with its associated brush, and also slidingly engages a gear which is driven from the main power shaft of the machine through a part which also has connection with the brush to oscillate it about the heel. The arrangement of these connections is such that as the sliding shafts are rotated while the brushes are oscillated along the sides and about the rear of a heel said shafts will follow the brushes and impart rotation to them simultaneously with their described oscillating movements.

Another very important feature of the invention consists in an improved means for automatically supplying liquid blacking or other coloring matter to the brushes and for reliably contr lling its supply in accordance with the requirements of the work. The blacking is preferably contained in a reservoir and is forced through suitable conduits to the brushes as they travel about the heel of a shoe. Under a convenient construction, a longitudinally bored piston is so connected with each of the brush guides as to be submerged in the liquid blackin and an adjustable stop or valve is arranged at one end of each piston in position to obstruct, more or less, the escape of the liquid through the same. A cylinder, also submerged in the liquid, is connected with a suitable pipe which supplies the blacking to each brush and the cylinders are arranged to telescope the pistons as the brushes move rearwardly, to thereby force the blacking through the cylinders and the pipes connected therewith to the brushes, in quantities determined by the distance of the stops from the ends of the pistons, said stops being capable of adjustment by the operator, through a handle or other appropriate means. Under this construction a simple and effective arrangement is provided for automatically supplying the liquid blackin in easily controlled quantities, and as eac piston and cylinder constituting a blackingsupply device, together with their conduit, are supported for movement about a common center with one of the brushes, it will be seen that as the brushes swing laterally in passing around the rear of a heel the alinement of said piston with its cylinder will be maintained notwithstanding the changes in the position of the brushes. Preferably, the stops referred to for controlling the quantity of blacking supplied to the brushes are in the form of members which are curved on arcs whose centers correspond with those about which the brushes swing, so that the stops in any given adjustment will remain the same distance from the ends of the pistons as they move laterally with the brushes. I regard this also as an important feature of the invention.

Other features of the invention, including important details of construction and combinations of parts, ill be hereinafter more particularly described and claimed.

In the drawings; Figure 1 represents, in front elevation, a machine embodying the present invention; Fig. 2 represents a perspective view of the principal operative parts of the same machine, the frame and reservoir being omitted for clearness of illustration; Fig. 3 is a plan view of the machine; 4 is a detail view showing one of the brushes and the devices for supplying the blacking, together with their operating connections; and Fig. 5 is a sectional detail view, on the line w-.r, Fig.

A pedestal 1, which constitutes 'a part of the main frame of the machine, supports a reservoir 3 to contain the liquid blaclring, or any other desired coloring matter. frame of the machine also supports bearings, one of which is indicated by the numeral for the power shaft 34 which is shown as carrying tight and loose pulleys 5 and 6, to which may be applied a belt for conveying power from a suitable source to the power shaft. The forward end of this shaft is shown as having fast thereon a worm gear 32 which meshes with a worm pinion 33, fast on a shaft 7 which is carried in bearings 8 supported by the frame. The shaft 7 is shown as having at its ends the worm gears 30 which, respectively, mesh with similar worm gears 29, carried at the lower ends of two shafts 85, which are rotatively sustained in bearing sleeves 39, located upon opposite sides of the center of the machine and mounted for turning movements in bearing sleeves 140, which are rigidly connected with the main frame. The sleeves 39 are rigidly connected with horizontal sleeves 139 which have casings to receive worm gears 28 to be driven by worm gears 128 carried by the shaft 35. Shafts 36 slide through bores in the gears 28 and The are caused to rotate with the gears by splines 50 which are carried by the gears and enter longitudinal grooves 51 in shafts 36, and the inner ends of these shafts have fast thereon worm gears which mesh with worm gears 52 carried upon the shafts of the brushes 12. Through the described connections, when the shafts 35 are rotated by power derived from the shaft 34, the brushes 12 will likewise be rotated. Each of the brushes comprises a main body of bristles 12, which is adapted to apply blaclring to the sides of a heel, and a relatively narrow set of stiffer bristles as for entering the crease formed between the counter portion of a shoe and the heel thereof, so as to apply the blacking thereto. The brush parts are mounted on a suitable shaft having at one end the gear 52, and rotatably supported at its opposite end in a guard 16 which is shaped to engage the counter portion of a shoe and to thereby control the position of the brush relatively to the heel. Scrapers 2?" having slotted arms 27 for adjustably securing them to the guards 16, are preferably arranged in connection with the brushes for removing the surplus liquid.

The arms 18 which constitute guides for the brushes, are connected at their forward ends rigidly to the sleeved extensions 189, and the brushes are supported for sliding movements on said guides by ways 161, which are herein shown as being rigid with the conduits 19 for supplying blacking to the brushes. The upper portions of the conrear ends of the arms 180 are connected pistons 14, having bores 42 therethrough, and arranged to aline with the cylinders 15. Located in suitable proximity to the rear ends of pistons 14 are two liquid-controlling valves or stops 17, which are curved on arcs whose centers correspond with the axes of shafts 35, about which the supports for the brushes and liquid blacking-supplying devices are arranged to swing. The valves 17 are shown as being connected and are arranged for simultaneous adjustment to ward and from the rear ends of the pistons 14 by a slide 17 0 which is shown asbeing provided with an angular portion having M an internal thread to receive the threaded end of an adjusting rod 53, which extends toward the front of the machine and has applied to its forward end a milled nut, or handle 20. By suitably rotating the nut 20 the valves 17v may be moved varying distances thereby permitting more or less of the blacking to escape from the pistons as the cylinders telescopically reciprocate thereover. By this means the quantity of blacking forced through the conduits 19 on to the brushes may be controlled, at the will 1 of the operator. The brushes are reciprocat-' ed along the guides 18 by the reversely arranged crank arms 37 which are carried by the shafts 35 and connected through links 13 with the brushes. As shown herein, the rear end of each link 13 is joined by a pivot 54 to an arm or extension from the conduit 19, although they may be oined to any other portion of the brush carrier, or parts connected therewith.

As explained heretofore, thesleeves 39 are free to turn in their bearings 140 in order that the brushes, their guides, and the blacking supplying devices may be capable of swinging laterally as the brushes travel around the rear curved end portion of a heel, and in conforming to heels of difierent sizes and shapes. Collars 24, having pins 31 thereon, are secured to the sleeves by screws 45 or other suitable means, and yielding means, as for example spiral springs 22, connect the pins 31 and act to hold the arms 18, the brushes, and other parts sustained by the sleeves 39 inwardly so that the brushes will be held yieldingly against a cam 38 which is supported rigidly from the frame of the machine. When, however, a shoe is positioned on the shoe support the heel will engage the brushes and the arms will yield outwardly so that the brushes are removed from engagement with the cam and are maintained in engagement with the heel.

The shoe rest or support 11 is shown as being sustained upon a block 44, the sup-' port having a longitudinal rib 46 to enter a longitudinal groove in the block and there'- by permit the support to move along the block rearwardly in positioning a shoe. The

block isalso shown as having a downwardly.

extending stem 47 which is guided in a tube 48 supported. from a part of the frame, and located to one side thereof the block carries a depending rod 148 which is thread-o ed for engagement with an internally threaded adjusting nut 21, which may be roughened externally for ease in manipulation. These parts provide for raising and lowering the block and shoe support in order to position the heel of a shoe on the support at the proper height relatively to the brushes. The shoe rest or support 11 carries a downwardly extending pin 41 which slides in an aperture formed in a rod 40. The rod 40 is supported for horizontal movements with the shoe support 11, and to this end its forward portion passes freely through an aperture in an upwardly extending bracket 54 carried by the frame, andits rear portion is similarly guided and sup-'' a forward direction beneath a roll 57 whose,

axle has bearing in brackets supported from a hood 58, which extends over and partly covers the reservoir 3. The arm 56 at its forward extremity carries the fork 10 which is shaped to embrace the rear or counter portion of a shoe and cooperates with the rest or support 11 in positioning the shoe relatively to the brushes. The forward ex tremity of the rod 40 is shown as being. threaded to receive an adjustable stop nut 25, and a spiral spring 26 is confined between the bracket 54 and the nut 25. This spring is normally under a suitable amount of tension, and acts to draw the rod 40, and hence the fork 10 and support 11 toward the front of the machine, and the distance that the rod may move in the opposite direction crease and be engaged by the adjacentpart of the counter. The shoe is then moved to the rear carryingv with it the rest 11 and The rear end of the fork 10, until the rod 40 is arrested bythe nut 35, which is ordinarily adjusted to position the heel with its breast in line with the centers of the brushes when they are nearest the front of the machine. The rearward positioning of the shoe causes the brush-carrying arms 18 to move apart and the brushes will then be held yieldingly against the heel. Power being now applied to the shaft 3% by shifting a belt to the tight pulley in the usual manner, the shafts 35 will be caused to rotate and the described connections therefrom to the brushes will cause them to move along the sides and about the rear portion of the heel, and also to rotate durin such movements. It will be understood that in traveling about the heel one brush ill follow the other, that is, starting ith the brushes in the position they are shown as occupying in Fig. 3, the one slightly to one side of the center of the rear end of the heel moves first laterally around the heel to the left and then forward toward the breast, while the other brush moves rearwardly along the right side of the heel until it reaches a position slightly beyond the center of the rear of the heel, and these movements of the brushes are then repeated in the opposite direction. During the rearward movement of each brush one of the cylinders will move telescopically over its piston and force the liquid blacking through the conduit and onto the brush, in quantities which will be regulated by the position of the valve 17, in the manner above described, a greater quantity of the blacking being forced through the movable cyinders when the valve is located close to the rear end of the pistons so as to obstruct or prevent its escape through the bores 4:2 than when the valve is moved away from said end and the blacking is thereby permitted to flow freely back into the reservoir.
