.To aZZ whom, t may concern Be it known that l, ANDREW AQCOOK,

a resident of frivin, in the county o f West moreland and AState of Pennsylvania, have .invented a newy and useful improvement in thereof. l

The objectof the invention is to provide a machine ot this 'character or simple con-- struction, less liable to get out of order,

more durable and more easily `and cheaply operated than prior machines for this pura pose.

- The invention comprises the construction and arrangement ot scribed and claimed.

In the accompanying rawing's Figure 1 is a side elevation of the mechanism of the machine, the casingbeing omitted; Fig. 2 is a front elevation ot' the mechanism on the upright or back board; Fig. 3 is a plan 'vieu' of the lower portion ot' the mecha.- nism showing the brush carriage in its rear most position; Fig". lis a transverse section parts hereinafter de- -on the line awa, Fig. 3; Fig. 5 is ahorizontal section of a portion of the saine on the line 5 5, Fig. 1; Fig. 6 is a vertical section on the line 8 Y of the electric cut-out and operating means illustrating the air pump and the control valve; Fig. J 1s a perspective view of the cam for moving the toe brushes, and Fig. 10`

f inclosed in a suitable casing vas is common with this type of machine, but no part of the casing'lias been illustrated; Y

Rising from the base are standards 3 which support .suitable guides 4 on the 'fois wardend ot which is the footV rest 5. illoiuited on the guides 4 to reciprocate 6, Fig. 3; Fig. 7 is a detailA view thereon is the carriage or carrier 't3 for lall of the brushes, one special at'eature oit the' present `improvement consisting,- in having all of 'the brushes mounted upon a 'single recip'roeating carriage or carrier, thereby 'i `whichn-ieshes on opposite sides with gears 13 and 14 secured respectively to shafts 15 and 16 also rotatably mounted in the depending portion '11 of the carriage G.

Abrush is provided on each side ot the foot rest to clean and' polish Athe sides of the shoe, these brushes being marked 1'? and 18, respectively, and are mounted on verti cal axes 19 which-are rotatable in bearings 2O in thc outer ends of arms 21 which are pivoted to the 'carriage 6 on the vertical pivots 22. To the lower end of each brush spindle 19 is secured a -bevel pinion 28 lneshing Witha similar pinion 2e', said-'pinions 24 being connected with shafts 15 and 1G, respectively, by means of flexible shafts 25 the outer ends of which are rotatable in bearings QG in a depending' portion of arms By means of the gearing described the brushes. 17 and 18 are positively rotated A from each other on the pivots 22. A spring thereof; Fig. S- is a diagrammatic View connects the arms 21 and normally holds the brushes toward each other, or in the position shown in Fig. 3. As the carriage 6 is reciprocated these brushes pass along?,` the sides of the toot rest, being spread apart by contact with the shoe being polishcfh and again coming together at the heel of the shoe, as shown indotted lines, Fig. 3.

The power forfrotatiu shaft 8 and reciprocating thecarriage 6 may be derived from 'any suitable source. -As shown, it is derived from an electric motor 30 mounted on the upright `or standard Q and having its armature sha-ft connected by belt 31 with a pulley .on shaft 33. This shaft is connected by'a suitable 4train of speed reducing gearing to a crank shaft 34e, said train oit .gearing comprising a pinion 35 on shaft t3 fineshing with gear 36 fast on countershaft -`,37 which carries a pinion 38 meshing with ."a gear 39 on countershaft'fiO, said last named countershaft carrying another pinion 41 meshin with a gear 42 on the crank shaft 34. Al ofthe shafts described are mount.- ed in suitable bearings in a web 43 projecti in from tl-e upright or standard 2. Any ot er suitable train ot speed reducing gear in ma be em loyed. R-o `be garriagerl is reciprocated from shaft '34 by means of crank 45 on said shaft 34 and connected by link 46 to one arm 47 of a three-armed lever' fulcrumed at 4g? and whose arm 49 is connected by link 50 to the carriage 6 by bolt or pin 51. It. is obvious that the rotation of vcrank 45 through the links and lever described imparts a reciprocating forward and backward a0 motion to the carriage 6, to carry the brushes 7 and 8 alternately from the full line position shown in Fig. 3 to the dotted line position shown therein.

The shaft 8 is driven directly from shaft a5 33 through intermeshing bevel pinions 53 secured respectively' to shaft 33 and to the upper end of a substantially vertical shaft 54 mounted in suitable bearings 55 on the standard or upright and at its lower end carrying a bevel pinion 56 which meshes with the bevel pinion 9 on the rear end of shaft 8. Consequently as the carriage 6 is reciproceted back and -forth rotary movement is imparted to the brushes 17 and 18 by the sleeve 10 which is splined to the rotary 4 shaft 8, as will be understood.-

In my improved machine the toe or upper .and forward part of the shoe is cleaned and olished preferably by a plurality of rushes, the drawing showing three brushes 69, 61 and 62, although two or more may used. The first brush 66 is preferably formed of bristles and serves to clean the shoe, the second also is preferably of bristles and serves to brush the shoe after the application of the blacking, while the brush 62 is formed of felt or the like and constitutes the polishing laitier. These brushes are held in a frame comprising side or end pieces 63 50 and 64 and cross 'connecting rods or pieces 65 and 66. At the forward ends of the side pieces 63 and 64 are bearings 67 for a shaft 68 to which the crushes are splined so as to slide thereon a 1d rotate therewith. The bearings 67 are also slidable on shaft 68, the latter being held against cndwise movement by having its outer end mounted in bearing 6 9 on an arm'70 which is secured toa horizontal rod or bar 71` sccured to the' rear end of the carriage 6. Secured to shaft 68 is a bevel pinion 74 meshing with a similar pin.- ion 75 having a shaft mounted in. bearing 76 and connected by flexible shaft 77 to a short 'shaft mounted in laring Ttin vthe l c5 lower end of bracket 79 depending jfrom the carriage 6, said short shaft being provided with a bevel gear 80 meshing with a similar gear 8l on the vrear end of shaft 15. rhe toe brushes are therefore positively rotated from shaft 8 through the train of' gearing 70 described. The toe brushes are movable laterally with reference to the carriage 6 so as to bring the several brushes in succession into operative position with relation t'o the shoe being polished. To this end the cross 7'5 rod 66 of the brush carriage or trame is slidable in bearings 83 on the rear ends of the arms or brackets 84 projecting rearwardly from carriage 6. The frame 63 is also provided with a downwardly projecting arm 8g 85 carrying a roller 86 4which travels on the rod or bar 71. The splined connection of the toe brushes with the shaft 68 permits of such lateral movement withoutbreaking the connection for rotating said brushes. g5

The mechanism for noving the brush csrriage or frame laterally comprises a cam wheel 87 rotatably mounted ena stud or spindle 88 carried by bracket 89 projecting laterally from the carriage S. This cam Wheel has projecting from its lower face a series of pins 90, the drawings showing six such pins. Secured to the base 1 is a standard 92 upon which is fulcrumed at 93 a relatively stationary cam 94, said cam 94 being free to rotate slightly on its fulc'rurn in the direction of the arrow 95 (Fig. 3), but being prevented from movement in the opposite direction by reason of its face 96 contacting with a portion 97 projectingr upwardly from 109 standard 92. A spring 98 holds the cam 94:

normally in contact with stop 97. The cam wheel 87, as stated, is carried by carriage 6, and in the rearward movement of said carriage one of the pins 90, specifically, that 195 which occupies the position so numbered in Fig. 3, passes inside or in front of the cam arm 94, .as is apparent from Fig. 3, so that in the further' return movement of said carriage 6 ythis pin is forced by the forward 110 face ot cam arm 94 to the position indicated at 99, Fig. 3, thereby imparting rotation to the cam Wheel 87 through an'arc of 60 degrecs. Consequently, for six complete reciprocations of carriage 6 the cam wheel 8 7 115 makes one complete revolution. This cam wheel has the cam segment 100 extending through a semi-circle and elevated above its main body, and which in the rotation of the wheel 87 contacts with the end piece 64 of" 120 `the brush frame and pushes the same laterallv toward the right, viewing Fig. 3. The end of cam segment 100 which first contacts with the brush trame or carriage is preferably provided with a small vertical roller 101 to reduce friction. A spring pressed pawl 102 is carried by wheel 87 and coperateswith a stationary ratchet 103 to prevent backward rotation .of the cam wheel.

The pins 90 and cum segment 100 are so 13o t line with the shoe.

back ard stroke of the carriage (l the cam' Wheel ST is given-a rotary step through degrees thereby causingr the end roller 101 of the cam segmentI to push the brush frame or carriage laterallyvabout one-halt of its full travel, thereby bringing brush 61 in This lateral shifting of the brush carriage occurs just after the blacking material has been sprayed thereonso that said brush 61 brushes otl' the excess blacliing,r material.y @n the next backward stroke of the carriage 6 the cam wheel 87 is 2given a further rotary movement through 60 degrees, thereby turning the cam segment sutliciently far to push the brush carriage fully overv toward theV right, viewing;

,Fig Si therebyY brinting bader brush G2 iul 'line with the shoe.

u cam segment 100 is of such lengt-h that it holds the brush frame or carriage' in its extreme right. position through three reciprocationsoi the carriage 6, thereby insuring a goed budino' action to polish the shoe. As soon as the end of cam segment- 100 passes the frame membertt-l the brush frame or carriage' is retractedfor pulled fully to the position shown in Fig. 3, by means of ahelical tension spring' 105 conneetingthe end member 023 of said car.- riage or trarne with one of the stationary arms 84 of carriage G.

it will be `apparent from the foregoing;`

description tliattlie carriage, (3 has two com` plete reciprocations with the brushes 1'( and 18 acting' agrainstthe s ides'and heel of the. shoeA and brush (l0 actingon the toe and front part of the shoe. At the end of the two reciprocations the blackinn is sprayed onto the shoe by means hereinafter described, and the carriage thenaxeain moves for 'ard and bach with the brusheslland 1S acting aga'ins-bthe sides and heel ot the lshoe and the brush 61 actingr on the toe and front part of the shoe. During the next three reciprocations of 'the 'arrialtre the brush G2 acts on the tce and 'front part. of the shoe. the sides and heelliein'gr acted on in all reciprocations by brushes 17 and 1S. A

The means 4for sp ayingl the hlacking on the shoe are as follows: (')n the base 1 are one or more vessels or tanks 1081er the blacking in a liquid -torni. and extending` from these are spray pipes 100. one Such pipeextending at each side oft-he foot rest the air pump and sprayers.

and provided with a plurality (preferablyV three) ot spray nozzles 1.10 located at such height and directed in such direction as to spray the blarltinp; upon the'shoe being cleaned..y ,Pr .t'erably also a pipe 111 connects the tanks 108 and is provided with nozzle '112 at the rear ol'the foot rest to spray blaclrinr' upon the heel of the shoe. The liquid blaclcing forced Jfrom the :spray nozzles by means of air pressure. this being supplied through a pipe or hose 113 connected to an air pump 114, and provided with branches 115' whose ends'proje/.ft into the, nozzles 110 and form with the latter atcmizers or sprayers ot a well lrnoan type acting' on the ejector principle. The air pump 111 is trunnioned at 11G on the uprightor standard 2 and has its piston open atively connected to a crank 11? -on the end of primaryY driven shaft 33. T he puinn opbut which is momentarily opened at theVV proper time. This valve shown at 118 mounted on the upriejht or standard and having the pipe 113 connected to its? outlet and a tlcxible pipe or hose 119 connecting its inlet with the discharge outlet olf the pump 114. This valve may be of any suitable type being; shown as a` typical three Way rotary or plug valve, the rot-ary member 120 having connected thereto an arm 121 to which is connected a spring' 122 which normally holds said arm against stop 122&s which position the valve closes connection between the air pump and sprayers. To open the valve the rotary plug;y is provided with another alim 123 adapted at the proper time to be contacted by a projecting lingeror cam 121 on an intermittently rotated shaft 125. such contactservingr to rotate 'the plug!l valve. against. the tension ot' spring 122 and momentarily open connection between Shaft 125 is mounted in a bearing; 126 in the web 4.3 of the standard or upright 2, and at one end is pro-vided with a six-armed star wheel 127- arranged to be actuated bya finger 128 on the shalt 31 which carries the crank tor nn parting reciprccatory movement to the calin. L

ringe G. Obviously the shaft 34 makes one rotation for each full reciprocation of carriage 6 and consequently. the shaft 125 is given one forward step movement at. 4each reciprocatiou of said carriage. T he `.ttiger or projection 121 is so located on shaft, 125 that it opens the valve al the proper time, to wit, after the shoe hasl been cleaned and when it is ready to receive the blocking.

The shaft 1'25 also serves to stop the machine after the pre-determinednumber of reciprocations of the brushes. which in the 4present machine consists ofsix. To this end the shaft 125 is provided with another prrr jection 130 adapted at the proper time to Contact with a shoulder on lever 131 which 'is pivotally connected to the lower end of the switch blade 133, the outer being plvoted at 134 and normally held by spring 135 between the terminals` 136. The projection 130 acting against lever 131 pushes the vlower end of the switch blade out of contact with the terminals and stops the motor 30, as Will be readily apparent. The outer end of lever 131 is provided with a projection 137 by means of which the lever 131 can be lifted out of engagement with the projection 130 to permit spring 135 to close the switch and start the machine. Projection 137 can be actuated either by hand or by a coin, the latter method'being generally used. The particular form of means for delivering tbe coin to this lever is not a partv and has not been of the present invent-ion' illustrated.

The operation of the machine Will be readily understood from the foregoin descriptlon, and briefl is as follows: 1 fter the user places his toot upon the 'foot rest 5 the lever 131 is disengaged from projection 4130 by pressing` down on the outer end 137 of said lever,.thereby closing the electric switch and starting t e motor. The latter communicates rotary movement to shaft 33, and from the latter rotary movement is communicated through the shaft 54 and intermeshing gears to the lower horizontal splined shaft 8. Motion is also transmitted from shaft 33 through the train of reducing gearing to the crank shaft 34, and the latter by means of the crank 45, lever 47 and connecting rods 46 and 50 reciprocates the carriage 6 back and forth on Athe guides 4L During this reciprocating movement the brushes 17, 18, and 60, 61 and 62are constantly rotated from splined shaft 8 through the connecting gearing and iiexible shafts described. The brushes 17 and 18 move toward and from each other as they pass over the shoe, being held in constant contact therewith by spring 28, and meeting both in front of the toe and behind the heel, thereby perfectly cleaning and polishing the shoe.

At each reciprocation of the vcarriage 6 the cam wheel 87 lis given one rotary step, and after the second reciprocation of the carriage moves the toe brush carriage or frame half Way over, bringing the middle brush 61 in line with the shoe.V At the end of the second reciprocation the 'air valve 118 is momentarily opened to spray the blacking onto the shoe. On the next backward reciprocation the cam wheel 87 is still further rotated and pushes the supplemental carriage or frame entirely over toward the right, bringing the buffing or polishing brush 62 in linewith the shoe, and during the further reciprocating movements of the carriage during the cycle7 the cam wheel 8 7 holds the supplemental carriage in this position, but at the completion of lthe cycle of reciprocation, to wit, at the end of the sixth reciprocation, the cam frees itself from the supplemental carriage and the latter is pulled back to normal position by spring 105. At the end of the Jsixth reciprocation the electric switch is opened by cam projection 130 and the motor'is stopped. .l

The necessary pressure of the side brushes 17 and 18 is secured by spring 28, although the flexible shafts 25 also tend to hold these brushes in contact with'the sides of the shoe. The necessary pressure of the toe brushes is secured by gravity. The carrier or frame for these brushes is practically pivoted on the rod 66, and the brushes are so positioned that as they pass over the shoethey are elevated, whereby practically the entire lWeight of the brushes, and their carrier and operat- I ing shaft is brought into play to pressythe .brushes against the shoe. If desired, a tension spring may be 'added to pull downwardly on these brushes, although this has been found unnecessary.

The machine is of simple construction comprising comparatively simple trains of gearing, and all of the brushes and their i1nmediate operating parts are carried by a single reciprocating carriage. Inthe simplest prior machines with which I am familiar it has re'quired a reciprocating carrier for -each of the said brushes 17 and "18', and a third carrier for the toe brush. In the present machine all of these are carried by the one carriage. `On account of' the simplicity. of the machine it requires less power to operate, is less liable to derangement, and more -reliable than prior machines for the same purpose.

Various-modifications can be made in the arrangement of parts without departing from the invention. Especially is it possible to substitute different forms of connecting gearing for the train connect-ing shafts 33 and 34, and for the train connecting shafts 33 and 8. Other gearing than the trains in- Y' cluding theA flexible shafts 25 and 77 may be employed for rotating .the brushes from longitudinal shaft 8.
