llo all whom it may concern:

Be it known that l', CHARLES P. STANBON,

.a citizen of the United States, residing at Lynn, in the county of Y)Essex and State of Massachusetts, have invented certain new and. useful improvements in Channel-Cementing Machines; and l do hereby declare the following to be a full, clear, and exact description of the invention, suoli as will enable others skilled in the art to which it appertains to make and use the same.

The presentinvention relates to channel cementing machines which are used in the manufacture of boots and shoes for apply- ,ing cement to the channel portion of the sole and to the backwardly turned channel flap preparatory to the operation of laying the channel flap and leveling` 'or beatingout the sole of the shoe. Y

The object of the present invention is to provide a machine by which this operation can be easily and quickly perforn'ied, and by which the desired amount of cement can be applied to the channel and to the channel fla p without wasting` the cement or applying it to other parts of the shoe, 4which are serious objections incident to the construction 'and operation of prior channel cementingl laid it must be moistened as otherwise it is liable'tov injury during the `iiap laying operation and can not be readily pressed down into proper position. 'The channel iap is moistened either before or after the channel cementing operation, and this is usually done by dipping the sole of the shoeinto water, the entire surface of the sole as well as the channel tlap being subjected to the the channel flap alone is moistened and a separate cementing operation is done away with.

In accordance with the present invention the cement is applied to the channel and channel flap by means of a brush. Coperating with this brush is a channel flap guide arranged to support the channel flap against the brush. This channel flap guide holds the channel flap in position so that cement is applied over its entire surface, but is not applied to the surface of the sole inside of the channel flap. Preferably a vibrating motion is imparted to the channel flap guide longitudinally of the channel flap, whereby the resistance offered to the feeding of the shoe beneath the brush is decreased and also the folds in the channel flap are straightened out and all portions of the flap are this feature of the invention contemplates the use of any suitable form of brush, a vibrating brush is preferably employed and means are provided for simultaneously vibrating the brush and the channel iiap guide in opposite directions longitudinally of the flap, whereby the tendency of one of these moving parts to move the shoe is counteracted by the other part and also the cementis more evenly and thoroughly distributed over the surface of the tlap.

, The invention contemplates the provision of a tank or reservoir for the cement and means for feeding the cement to the brush,

and in order to prevent the cement being supplied to the brush except when a shoe is presented thereto, a feature of the invention consists in providing means actuated by the shoe when presented to the brush for con` trolling the flow of cement to the brush.

'This means preferably consists of a valve located in the passageway leading 'to the brush, which valve is adjustable to vary the amount of cement supplied to the brush so that the tlow of cement can be regulated by the operator to suit the character of the work being operated upon, and the cement can be applied without any waste.

That feature of the invention which refio ' ably provided i'n the channel vflap guide' struction in which a hollowr channel flap guide is provided, the guide being connected to a supply of water and the passageway in the guide opening lat the inner end of the guide so that the water is delivered at the base of the-flap.` In order to stop the ilow ofwater from the guide except at such times asl the shoe is in position, a valve is preferwhicli is operated by the upward movement of the guide when the shoe is presented. .to the cement applyin brush.

Inl addition to t e features of inventionabove referred to, the machine hereinafter i specifically described, embodies certain novel features ofY construction and arrangement,

'inc

'the advantagesof which will be ohvious to those skilled in the art from. the following description taken in connection with the accompanying drawings, in which- Figure 1 is a view' in side'elevation of a' machine vembodying the various features of the invention in their preferred form, Fig- 2 is a sectional view of the front portion of the machine frame and the parts supported thereby, Fig. 3 is a view in side elevation of the front portion of the machine frame looking in the opposite direction from Fig. 1, 'and Fig. t is a view infront elevation of the parts illustrated in Figs. 2 and 3.

Referring `to the drawings, 1 indicates what may he termed the frame of the niachine consisting of a casting secured upon the upper end of a standard 2.

3 indicates the cement tank or reservoir whichvis supported upon the frame 1 and preferably cast integral therewith. At its upper end the tank 3 is provided with an opening which is closed by a cover 4, the

, cover being firinlv held in position by means 'ofa screw threaded stud 5 pro3ect1ng downwardly from the cover and screwing through a cross web in the upper part of the tank. At itsz lower end the tank 3 communicates with ya chamber formed in the frame l in which is mounted a Shaft .6. y'lhis Ishaft is journaled ina bushingremovably secured inthe rear end of the chamber andis provided at its outer end witlia-pulley 7.' Suitable packing disks are 4provided for preventing the escape of the cement at this vend-.of the chamber. Below the opening 'leading to the cementv tank the shaft Gis wardend is provided with a feed worm9 by' which the cement-is'foigced throughv the passageway leading't'othe brush, this passageway being lin communication with the front' end of the chamber inathe frame as willbe hereinafter described. 'From the front end of the chamber a passagewayjalso leads to the-upper portion of the cerneilty tank, the

passageway being 'formed in lugs projecting from theframe and from 'the upper. end

of the cement tank. and connected by a .pipe

10. This passageway forms a by-pass through which, the surplus cement is forced back in tothe tank. In the upper end of this passageway a valve 11 is vprovided which, is ressed, against its seat at the up-' per end o the pipe 10hy ,means of a spring y v 12 coiled around the stem of the valve and interposed between the head of the valve and an adjustable screwthreaded stop 13. Byturningl the stop 13 in one'directionor the other, the tension-ot the spring 12 can be adjusted and thereby the pressure 'at which the'cement is supplied Ato the cement 'applying brush can be `regulated as desired and an even flow. of the cement to the brush insured.l

i The cement applying brush isindicated at 14 and is mounted upon the'lower end of a brush carrier 15 consisting of an arm pivotally mounted.y at its upper end upon a stud- 16 projecting from the front end of the frame 1. The socket of the brush has-a screw threaded engagement with the lower end of the brush carrier anc thus reinovably secured thereto as indicated. in Fig. 2. The stud 16 is provided with a passageway 'opening at one end into the chamber in the frame 1 and at the other end into a passageway formed in the stud and inthe hruahVV carrier 15. valve casing 17 is located which consists of a tube the upper end of which has a screw brush 1-1. The valve casing 17 is` parovidedl above the socket of the-brush with a series of openings 18 with which a. valve 19 mounted in thevalve casing is arranged to cooperate. This valve is provided with a downwardly extending stein, the lower end of which is yarranged to contact with the shoe when presented to' the brush. The valve is arranged to inove vertically in the valve casing, and when' in its lowest position, as illustrated in Fig. 2, closes the openings 18 in the valve casing. When the shoe is presented to the brush., the valve is raised andthe openings 18 are wholly or partially -uncovered Vto allow the, cement to flow ln'this latter passageway a" yi'oo threaded engagement with the brush carrier weet/ee ing the screw 21 in one direction or the other7 the stop rod 20 can be adjusted to limit the upward movement of the valve 19 so thatl the valve when raised will either partially or completely uncover the openings 18 in the valve casing. The iowI ot' the cement to the brush can thus be regulated to suit the character of the work being operated upon. In case the valve 19 remains raised after the shoe is removed from contact with the brush, it can be depressed by depressing the rod 20 against the tension ot' the spring 22. By reason oi' the screw threaded engagement of the Valve casing 17 with the brush carrier 15 the Valve casing and the Valve can be adjusted bodily to bring the lower end of the Valve rod into the desired position.

'ln order to enable the operator to readily hold a shoe in position to be operated upon by the cement brush and to aid the operator in guiding the shoe, an edge rest or guide 23 is provided at the rear side of the brush against which the edge otthe solebears during the cementing operation. The shank of this edge guide has a sliding engagement with a block 2l mounted for Vertical adjustment upon a stud S25, a clamping bolt 26 serving to clamp the shank of the guide and the block Q4 in adj usted position.

The brush 14. is removably mounted upon the lower end of the brush carrier 15 as has been stated, so that a brush can be readily removed and another of a ditterent'size substituted therefor when the nature of the work requires such change. ln order to lavoid frequent changes of the brush, the

machine illustrated is provided with means for compressing the bristles of the brnsh so thatthe same brush can be used upon ditl'erent classes of work. These means consist of a plate QG located at the front side of the brush kand carried upon the lower end of a leaf spring 27. This spring is secured at its upper end to the brush carrier 15 by means ot' a screw4 and intermediate yits ends is acted upon by an adjusting-,screw 28 by means ot which the plate Q6 can be forced against the bristles of the brush.. .lf desired the guide 253 can be adjusted so as to compress the bristles et the brush on the opposite side. IThe adjustment oit the plate 2li leither alone or in conjunction with the guide 23 compresses the bristles ot the brush so that the working face oit' the brush is made to correspond in width to that of the channel iiap and channel portion ofthe solo which are to be supplied with cement.

rlhe channel tia-p guide is indicated at 29. This guide is located at the t'ront `side ot' the brush and is arranged to extend beneath the clnumel tlap` and hold it up against the brush during the operation ot the machine. As shown inA the drawings, the guide is mounted upon the lower end of a hollow rod 30 which is mounted. to slide vertically the lower arm of a frame 31 pivotally mounted upon a stud projecting from a bracket 32 secured to the trame 1 ot the machine.' lVithin the hollow rod 30 a hollow rod 33 is located the upper end of which is clamped in the upper arm of the trame 31. The channel liap guide is held yieldingly in its lowest position by. ine-.inset a spring 34 coiled around the rods 30 and 33 andv interposed between the-upper arm ot the trame 31 and a block 35 secured to 'the rod 30, the downward movement ofthe rod 30 being limited by the contact, ot the block 35 with the lower arm of' the trame 31. The blocl 85 extends laterally on one side of thel rod 30 and is provided with a slot which engages a guide rod 3G upon the lower arm oi? the frame 31, whereby the rodBO is held from rotation. j

In the machine illustrated in the drawings, the channel Hap guide E39 is utilized as a means tor moistening the channeliap and to this end it is made hollow, the passageway' in the guidebeing in communica tion with the passagewaytormed by vthev hollow rods 30 and 33 andl terminating at the inner end ot' the guide. Water supplied to the passageway is thus delivered at the base of the channel flap lwhich is thus mois. tened without any liability of injuryfto` the shoe. The water is supplied from a" tank 37 mounted upon the cement tank 3. through a flexible tube connecting with the .upperf end ot therod It is desirable that water should be delivered from the channel. guide only at such times as a shoehis being operated upon and accordingly the machine illustratedin the drawings is provided with means, actuated when the shoe isaplaced in position to. be operated upon, tor controlling the .flow of water. As illustratori., this means .comprises a valve 38 which .is -in `they form of a rod mounted to reciprocate in the rod 33 and coperate with a yalvevseat near the lower end of therod. The valve rod is held against theseat by means ol." a coiled spring interposed between a shoulder` on the rod and a stop screw in the jupperfend of the rod. The lower end ottheyalre-rod rests upon a screw 40 mounted-inthe channel flap guide 2), whereby,` lwheizthe guide is raised by the engagement of a 'shoe there` with, the valve' rod littedt'ronii `its seat and water is allowed to tlow through the passageway in theguide The inneiend ot the screw Ll() is shaped to coj'ierate.with a. valve seat formed in the channelftlap guide7 as illustrated in Fig. 2, so that by adjusta, ing the screw a() the an'iountiotwater dee, lirered upon the channel-flap can-he regu-y lated or the waterean be shut''otlTentirely iit desired.

The channel Hap guide 29 and the cement.. applying brush 14 are vibrated simultane-` shaft 41 mounted in bearings in the frame of the machine and provided. at its rear end with a driving pulley 42. 'At its front end l the shaft 41 is provided with a crank pin 43 .the edge of .tending under .the channel flap.

which engages a block 44. mounted in a vertical slot 1n the rear sidey of carrier 15. By means of this construction the brush carrier 15 is oscillated upon the pivot stud 16 by the rotation of the shaft' 41. At its front end the-shaft 41 is lalso pra vided with an eccentric 45 which, tlm gli an eccentric-strap and link 46, imparts 'an oscillating movement to the frame 31 in which the channel iap guide 29 is mounted. As is clearly shown in Fig-4, the crank pin 43 and the eccentric 45 .are so placed with relation to each other on the shaft 41 that the brush carrier 15 and frame 31 are-oscil lated in opposite directions.

It is desirabletliat means be provided for adjusting the `channel flap guide 29 toward and from the edge guide 23 in order to bring it into the proper position to act upon different kinds of work. To this end the bracket 32 upon which the :trame 431 is mounted is adjustably secured to the frame of the machine by means of a bolt 47 passing through a slot' in the bracket, as is clearly shown in Fig. 2. To allow this adjustment to be madc,the link 46 is connected to the frame 31 by means of a pin 48 passing through two lugs on the frame 31 and through the end of the link which is received between the lugs.

In-the operation of the machine, the parts being lin the positions illustrated in the drawings, the shoe is presented tc the brush, the sole bearing against the guide'23 and the channel flap guide 29 ex- The upwardpressure ofthe shoe against the brush raises the .valvel19 and allows the cement to be forced from the chamber in the frame 1 through-'the passageway inthe stud 16 and brush carrier 15 and, through the openings .1'8 to the interiorf the valve casing 17 and to the bristles of thebrush, the pressure on the cement delivered to the brush depending upon the adjustment of the spring 12 of the' 'valve 11 and the amount of cement dependinlg' upon' the adjustment of the stop rod 20. '.1 erup'ward movement of the shoe against.

the brush also raises the guide 29, thereby lifting the valve rod 38 and allowing water tof .flowthrough the guide to the base of the' flap. The'brush and' guide vibrate rapidly in opposite directions and as the shoe is fed lforward by the perator, the flap is held up against the-brush by the guide so that ce' ment is applied'only to the channel portion vof the sole and to the surface ofthe channel.

-the brushA `the machine/is not in use,

flap. The brush moves back and forth over the surface of the channel {iap and evenly a distributes the cement while .the vibrating movement-of the channel iiap guidesmooths outl causes all portions of its surface tobe acted upon -by the brush. The vibrating move-y mentI of the channel flap guide allows the' shoe to he easily fed by the operator, any

'tendency of the guide to move the shoe in the hands of the operator being counteract-y the folds or puckersfin the iiap and ed by the brush, the movements of which take place as the shoe is removed, the valves 19 and are returned to their normalposi-A tions and the z'dow of cement and water is 'in.--:.tantly stojiiped. lf at any time 1t 1S def in the opposite direction.4 As

sired te shutod the supply of cement fromthe passageway in the brush carrier, thls can A lhe awomplishcd by turning a valve 49 which` controls the passageway through the stud 16.

It will be seen that in the machine above described, the parts may be so adjusted and arranged that the cement'willbe applied. only to the channel portion of the sole and to the channel flap, that cement is supplied to the brush only while shoe is being operated upon,vand that the flow of cement to the brush can he regulated v so that only the necessary amount of ycement is applied to the shoe. lt will also bessen that the.'v ement is not exposed to the air Abefore reac. ing the brush so that there -is no loss of cement by evaporation and no liability of the passageway between the tank and the brush becoming clogged. The cement is exposed to the air only after reaching the brush .and in order to prevent evaporation'of the cement left on. the brush and clogging of the brush uhr-,n not in use, a cup 50 is provided (see Fig. 1) carried upon a bent rod 51 clamped to the frame of the machine.

When the machine is in use, this cup is swung back` in combination, a cement applying brush,

and a channel flap guide arranged to support the iapin contact with the brush, substantially as described. y
