26 Claims.

This invention pertains to improvements in apparatus for use in applying a coating to shoe parts and is illustrated herein as embodied in a .counter pasting machine of the character illustrated in application Serial No. 550,764, filed August v23, 1-944 (now United States Letters Patent No. 2,370,917, granted March 6, 1945), in the names of Fred Ricks and Charles M. Bagshaw.

It is customary to apply ,a coating of adhesive to the inside and outside surfaces of premolded counters so that when they are inserted between the outer layer of the ,shoe upper materials and the lining at the heel end of the shoe, in assembling the upper materials on a last,.and the whole is subjected .to the subsequent heel seat lasting operations, a composite back part will be formed the component parts of which will .notslip relative to each other in the finished shoe. In the above-mentioned application there is illustrated and claimed a machine for applying adhesive, hereinafter called paste, to a premolded counter, in a semiautomatic manner. Such a machine will frequently be used in conjunction with heel seat lasting machines to furnish freshly coated counters at a rapid rate and in such timed relation to the heel seat pulling-over and lasting operations that a freshly coated counter will constantly be in readiness for the succeeding operations. The aforesaid prior machine comprises a pair of oppositely disposed parallel applicator brushes, one of which is furnished with paste, and between which the diverging legs of the counter are moved in succession, a reciprocating crosshead being provided for moving the counter linearly with respect to the applicator brushes, open end first, to advance one leg between the brushes, then to rotate the counter as the rounded end reaches the brush engaging the inner side of the counter, and then to continue the linear movement of the counter in the same direction, rounded end first, to draw the other leg between the brushes. The movement of the crosshead is then reversed and, hence, carries the counter back to its starting point, the linear and rotational movements of the counter being duplicated in the opposite direction so that two coats of paste are applied. For reasons assigned in the prior application, it is desirable to omit the application of paste along the top and bottom marginal edges of the counter from the rounded heel end forwardly and also part way around the curved forward ends of the legs. Accordingly, in the prior machine, shielding members were provided for effecting protection of these areas. The shielding means provided for protecting the top and bottom edges was entirely satisfactory, but that which protected the forward curved marginal end portions of the legs necessarily extended transversely of the counter and applicator brushes, and each time the counter moved between the applicator brushes the transversely extending shielding means were given a heavy coating of paste. The movement of the crosshead spattered the paste and made it necessary .to clean the machine frequently to avoid soiling the work. Moreover, while the aforesaid machine was provided with shielding means for protecting the curved forward outside surfaces of the diverging legs of the counter adjacent to their end portions, no means was provided for protecting the corresponding areas at the inside of .the'legs.

An object of this invention is to provide a semiautomatic adhesive applying machine by the use of which paste may be applied to the inside and outside surfaces of a p-remolded counter, provision being made for applying a coating to the central portion of the inside and outside surfaces while omitting the marginal portions extending from the rounded heel end forwardly and around the curved ends of the legs without employing shielding means to protect the curved forward ends, thereby improving the cleanliness of the machine and rendering it less complicated.

In its broadest aspect, invention resides in applicator means, means for supporting a shoe part adjacent to the applicator means, and means for causing relative movement of the applicator means and the supporting, means to bring the shoe part into contact with the applicator at a point spaced from the end of the shoe part, in the direction of relative approach, and then to move one over the other to spread the paste over an adjacent portion of the shoe part, leaving a clean margin. More specifically, this is accomplished the instant machine in a novel manner by a counter supporting and clamping means, applicator means, and means for moving the counter supporting and clamping means transversely of a part of the applicator means in such a position with respect to the direction of movement that the marginal portions of the legs of the counter adjacent to their ends lie outside the field of action of the applicator means. Thus, they pass above and beyond the applicator means Without engaging the same and hence without receiving a. coating of paste. During the application of the coating to the one surface of the counter, means associated with the means for z. moving the counter moves another part of the applicator means, adapted to coat the other surface of the counter, in timed relation to the movement of the counter to move this applicator means into and out of engagement with the legs at ,points substantially opposite the points of engagement and disengagement of the one surface of the counter with the one part of the applicator.

The applicators consist of a pair of brushes, one of which is movable, one of the brushes being supplied with paste and the other receiving a supply of paste from the first brush during those periods when no work is passing between them. The movable one of the brushes receives paste directly from a paste container, and, in accordance with a feature of the invention, means is provided for holding the movable brush in contact with the fixed brush for a predetermined time, then for moving the movable brush relative to the fixed brush to admit the work, and then through a predetermined path to cause it to engage predetermined portions of the counter. To render the supply of paste uniform, means is provided for holding the container at a fixed position with respect to the median of the range of movement of the movable brush during the latter part of its movement, thereby to prevent undue pressure between the brush and the container.

In the illustrated machine, the counter is placed astride a support which has a contour which is substantially complementary to the contour of the, inside of the counter and clamping means are provided for holding the counter on the support, The natural springiness of the counter causes the legs to grip the support even after the clamping means are released, and still another feature of the invention resides in means associated with the support which will automatically disengage the counter when the clamping means are released.

In the machine disclosed the counter is moved in a linear direction in a path contiguous to an applicator and supported during its linear movement in positions in which those portions of its surface near the ends of its legs will move beyond the field of action of the applicator without engaging the applicator, thereby leaving these portions free of paste. Simultaneously, an applicator for applying paste to the other surface of the counter is moved in timed relation to the movement of the counter to cause it to engage and disengage this other surface of the counter at points spaced from the ends of the legs, thereby leaving corresponding uncoated areas on both surfaces of the counter near its ends.

Other features of the invention, in addition to those above referred to and including improved details of construction and combinations of parts, the advantages of which will be clear to those skilled in the art, will be hereinafter more particularly described with reference to the accompanying drawings, in which Fig. l is a view in elevation of the right-hand side of a machine in which the invention is embodied;

A machine of this general type is illustrated and described in the above-mentioned application Serial No. 550,764, Patent No. 2,370,917. However, since numerous changes have been made in the construction of the aforesaid machine in conjunction with the novel features of the present invention, the following description of the machine will be given in sufficient detail to afford a clear understanding of the invention with a minimum of reference to the prior machine.

Referring to Figs. 1 and 4, a rectangular channel-shaped frame I0 is fastened in a horizontal position upon the upper end of a vertical pedestal I2 which rises from the floor and forms a base for the machine. The rectangular frame is adapted to support in operative relation means for applying a coating of adhesive, hereinafter called paste, to a preformed counter and means for holding the counter and moving it progressively with respect to the applicator means in such a manner as to apply paste to both the inside and outside surfaces of the counter, as illustrated in Fig. 8, except for the top and bottom marginal portions extending forwardly from the back part to and around the curved open ends, which are left free of paste.

The means for applying the paste consists of a pair of juxtaposed brushes M and I6 (Fig. 4) mounted for rotation with parallel shafts l8 and journaled in

bearings

22 and 24, respectively. The bearing 24 is formed in an upwardly pro- J'ecting bracket 26 fastened to the left side of the frame to. The bearing sleeve 22 is pivotally mounted at 28, for reasons which will appear hereinafter, in a forked extension 21 of the bracket and is urged to turn in a counterclockwise direction about its pivot by a springpressed plunger 3!]. The plunger 30 is slidably seated in a bore 32 formed in the upper end of the bracket 26 beneath the bearing sleeve 22 and a spring 34 is disposed in the bore 32 behind the plunger. a portion of the spring extending into a bore 35 formed in the lower end of the plunger.

Pulleys

38 and 40 are fixed to the shafts l8 and 2c and are connected, as will be seen by reference to the prior application, to a source of power (not shown herein) for rotating the brushes l4 and It in opposite directions, as indicated by the arrows in Figs. 1 and 4. The brush I4 is adapted to apply a, oating of paste to the outside surface of the counter and is about 6 inches in diameter, having relatively long, flexible bristles which will conform readily to the shape of the counter. The brush it rotates in a clockwise direction (Fig. 2) at about 60 R. P. M. The brush it is adapted to apply paste to the inside surface of the counter and is about 2 inches in diameter, having relatively long, flexible bristles which will conform to the inside of the counter. This brush rotates at about the same peripheral speed as the brush l4 but in a counterclockwise direction and it is to be observed that the shafts of the brushes are close enough together so that the bristles of the two brushes intermesh by an appreciable amount (Fig. l). The brush I4 is furnished with paste from a receptacle 42 (Fig. 2) and the brush l6 receives paste indirectly from the brush M during those periods when no work is being passed between the brushes.

The receptacle 42 (Fig. 4) is mounted above the topmost point of the brush I 4 in substantially tangential relation thereto upon a shelf 44 which is fastened to an arm 45 pivoted at 48 to a post 55 bolted to a bracket 52 which, in turn, is bolted to the right-hand side of the frame H). The bottom. side of the paste receptacle '42, as will be seen by reference to Fig. 2, is provided with a rectangular opening 54 through which paste may run onto the bristles of the brush Hi. The size of the opening 54 may be controlled in accordance with the viscosity of the paste, to permit a larger or smaller quantity to flow through it, by a slide valve 55 having an opening 58 therein corresponding in size to the opening 54 in the bottom of the receptacle. The slide valve 56 consists of a flat plate which is slidable in a groove (Fig. 4) formed in the upper face of the shelf a l. The valve 55 has at one end an upwardly projecting flange fill which serves in co-operation with a pivoted lever 52 to slide the valve to the right or left to open or close the valve. As will be seen by reference to Figs. 1 and 2, a plate 64 forming part of the lever 52 and having a bifurcated end 55 is pivoted at 58 to a bracket 1i) fastened to the side of the receptacle 42 in such a position that the upper end of the flange GEE projects into the bifurcation. The lever 62 is rigidly fastened by screws 12 to the plate M in a position to lie beside one end of the receptacle 42,'as seen in Fig. l, and on the upper end of the lever 52 is a pointer which may be moved over a scale 14 marked on the side of the receptacle. The graduations on the scale represent valve openings for varying conditions of viscosity. A small knob it formed on the pointer serves as a hand hold to move the pointer over the scale in one direction or the other. It was found that When the valve 56 was closed the ends of the bristles of the brush M would rub against the bottom face of the valve and cause some wear, which is undesirable, and, furthermore, when the machine was at rest, the under surface of the valve would deflect the bristles and, if left in this position for any length of time, a permanent distortion of the ends of the bristles would be brought about. To avoid this, a recess l8 (Fig. 2) is formed in the bottom side of the valve plate 55 and in the shelf M to accommodate the projecting ends of the bristles.

A counter 18, as shown in Fig. 8, is preformed and has diverging legs joined by a rounded back part, and in the illustrated machine means is provided for moving the counter, open end first, in a linear direction to advance one leg between the brushes I 4 and it until the inner surface of the rounded end substantially engages the brush It, then to rotate the counter to bring the other leg into a corresponding position, and, finally, to resume the linear movement of the counter in the same direction, rounded end first, to draw the other leg between the brushes. In the instant machine, in order to prevent the application of paste to the curved portions near the ends of the legs, the means for supporting the counter is constructed to hold the legs of the counter at an angle of about 20 to the horizontal and, as a result, the curved portions near the ends of the legs at the inside of the counter lie outside the field of action of the brush it and when the legs are moved across the brush those portions do not engage it. In order also to preserve the end margins of the outer surfaces of the legs free from an application of paste, the brush it adapted to apply paste to the outer surface of the counter is moved in timed relation with the movements of the counter to bring it into contact with the legs back of the marginal end portions thereof.

The means for moving the counter 19 transversely of the means for applying paste thereto, that is, the brushes I4 and It, comprises a rotatable counter holding member 8%) (Fig. 4) and a rotatable counter clamping member 82. Referring to Figs. 4 and 7, the counter holding member consists of a substantially V-shaped block 84 which has a substantially V-shaped recess 86 (Fig. 7a), thereby forming a member having diverging legs joined by a rounded, closed end which conforms closely in shape to'the molded counter and along the legs of which the legs of the counter are adapted to lie. In the position shown in Fig. 4. the block 84 is situated close to the left side of the brush I5 and straddles the shaft 20. A hub 88 having a substantially V -shaped recess 89 (Fig. 6) therein is formed integral with the block and extends to the left, as seen in Fig. 4, surrounding the shaft 20, the left end of the hub being supported for free rotation upon a bearing 90, the latter being fastened to a crosshead 92 reciprocable along the base I0. Near the inner end of the block 84, the lower end as seen in Fig. 7, there is formed a roove 94 which extends from the open ends of the legs of the V-shaped block around the outside of the rear rounded end portion thereof. This groove 94 is adapted to receive an inwardly bent bottom flange 8? of the counter, thereby to protect it from an application of paste as in the prior machine. A pulley I (Fig. 4) is secured to the hub 8.8 against a flange IOI and adjacent to the bearing 99, the pulley having a substantially V-shaped recess 96 therein (Fig. 6) which corresponds to the substantially V-shaped recess 89 in the hub 88. The pulley I00 provides means for rotating the hub and to this end a pair of grooves I02 and HM, formed in the peripheral surface of the pulley, are adapted to receive the overlapped opposite ends of a chain I66 (Fig. '7) which are placed one in each groove and are pinned therein. At the extreme left end of the hub 88 (Fig. 4) there is fastened a disk I 88 which abuts the outer surface of the bearing 90 and, together with the pulley iilii, prevents axial movement of the hub laterally of the bearing 9% The disk I08 has a substantially V-shaped recess I09 therein (Fig. 6) to correspond to the recesses in the hub 88, the pulley sec, and the V-shaped block 84. To prevent upward movement of the hub 88 away from its bearing 9i an arcuate flange Ill) (Fig. 4) nearly as long as a semicircle is formed at the left edge-of the bearing in a position 7 to project into a circular groove II2 cut into the disk I06. It is to be observed (Fig. 6) that, as in the prior machine, to permit movement of the bearing beneath the shaft 20 during the linear movement of the counter holding and clamping means, the bearing 90 is made slightly less than semicircular so that its upper extremities terminate below the shaft 20.

The clamping means 82 which cooperates with the supporting means 80 in holding the counter, during its linear movement, is mounted at the right-hand side of the brush I6, as viewed in Fig. 4, upon a horizontal shaft II4 which is rotatably mounted in a split bearing II6 (Fig. 4), the latter being formed integral with a post II1 (Fig. 9) on the crosshead 92. Th axis of the shaft H4 is coincident with the axis of rotation of the hub 88. The split bearing H6 is provided with a pair of bosses IIB (Fig. 7) which are joined by abolt I20, the bolt passing loosely through one of the bosses and being threaded into the other. A spring I22 is placed between the head of the bolt I20 and the boss through which the bolt passes loosely so that by rotation of the bolt the elements of the hearing may be drawn together about the shaft I I4 yieldably to grip the shaft, the adjustment of the bolt affording means for varying the frictional resistance to rotation of the shaft. On the inner or left-hand end of the shaft II4 there is formed a rectangular shaped projection I24 which terminates at its extreme left end in a block I26 substantially V-shaped in side elevation (Fig. and corresponding to the block 84 except for the fact that there is no V-shaped recess therein. The block I26 has a sloping peripheral surface I28 (Fig. 7) over which the marginal edge of the counter lies. The clamping means consists of a pair of thin, elongated plates I30 (Figs. 5 and 7) which are yieldably urged toward the sloping surface I28 of the block I26, thereby to engage the marginal edges of the counter and hold them in against the diverging legs of the substantially V-shaped block I26. Eachplate I30 has a split pin I32 (Fig. 7) formed near one edge between its ends and which is adapted frictionally to fit into a bore I34 formed in a supporting member I36. Each supporting member I36 is, in turn, forked and pivotally mounted upon the ends of a pin I30 which is journaled in a boss I40 formed on the rectangular member I24. By the aforesaid construction, each plate I30 may turn about the axis of the pin I32 to compensate for variations in the thickness of the edges of the counter along the legs thereof and may be moved to and from the periphery of the V-shaped block I26 to permit introduction and removal of the counter. To hold the plates I30 yieldably in engagement with a counter on the block I26, a pair of springs I42 and I 44 (Fig. 5) is provided, the opposite ends of the springs being hooked between the opposite ends of a pair of bars I46 which, in turn, are fastened by screws I48 to the supporting members I36. It is to be observed that the plates I30 engage the marginal edge of the counter from the rounded, closed end forwardly to the open ends of the legs but do not extend around the curved forward ends of the legs as in the machine of the prior application. Hence, these plates provide means for shielding only the upper margins of the counter.

Mounted on the rectangular member I24, which is integral with the shaft II4 of the counter clamping means 82, and slidable thereon transversely to the axis of said shaft is a wedge-shaped block I14 (Fig. 5) which has a, bifurcation I16 at its small end adapted telescopically to fit over the rectangular member. The wedge-shaped block I14 has a pair of sloping surfaces I18 adapted to engage a pair of rollers I (Fig. 4) which are mounted for rotation on a pair of posts I82, the latter being fastened to and projecting inwardly from the pivoted supporting members I36. Hence, by forcing the wedge-shaped block I14 inwardly between the rollers I80 the plates I30 may be moved apart against the action of the springs I42 and I44 to release the counter. When the force applied to the block I14 is withdrawn, the plates are urged together by the springs I42 and I44 to clamp the upper edge of the counter in place. To assist in guiding the wedge-shaped block I14, a hollow stem I13 (Fig. 5) is provided in the bifurcation I16 of the block and is slidable in a bore I15 formed in the member I24. A spring I13 disposed in the hollow stem bears against the bottom of the bore I15 and assists in moving the block I14 from between the rollers I80. The means, including a stop disk 234, for forcing the wedge-shaped block I 14 inwardly to separate the plates will be described hereinafter.

In the prior machine it was found that some counters had so much springiness that they hugged the counter holding and clamping means even after the clamping plates were withdrawn so that it was a little troublesome to remove the coated counters without taking hold of the pasted areas. In order to overcome this situation, the rounded rear end portion, denoted I58, of the V-shaped block I26, as shown in Fig. 10, is made separable therefrom, and is yieldably urged away from the block by a pair of parallel plungers I60 which are slidably received in bores I62 formed part way through the V-shaped block. The plungers I60 have reduced ends I64 which are fixed in the rounded end I56. In the bores I62 behind the plunger are disposed springs I10 which urge the plungers out of the block and consequently hold the rounded end I58 spaced from the block. In alinement with the bores I 62 are smaller passages which extend through to the front face of the block and through these pass reduced necks I66 formed on the rear ends of the plungers. A pair of collars I12 are fixed to the reduced necks of the plungers and by contact with the front face thereof prevent the springs I10 from forcing the rounded end I58 too far to the rear of the V-shaped block I26.

When the counter is mounted on the counter holding and clamping means, it is pushed into place with sufficient force to press the rounded end I58 into engagement with the major portion of the block I26. The counter is held there manually until the clamping means I30 comes into effect and grips the counter with sufficient force to held it in place against the tendency for the rounded end I58 to disengage it from the block I26. When the clamping means is released, after the pasting operation, the rounded end I58 will spring rearwardly, thus disengagin the counter. Hence, if there is a tendency for the counter to cling to the supporting and clamping blocks, the

rounded end I58 will disengage the counter so that it may readily be withdrawn by grasping the uncoated flange 81, for example.

A pulley I84 (Figs. 4 and 7) similar to the pulley I00 is fastened to the shaft H4 and is provided with a pair of grooves I86 in which the ends of a chain I68 are fastened (Fig. 6), thus providing means for rotating the shaft, and consequently the counter clamping means. The right hand flange of the pulley, as seen in Fig. 4,

is somewhat larger in diameter than the rest of the pulley and is held against the bearing II6, thereby to prevent axial movement of the shaft I I4, by the overlapping heads of screws I85 (Fig. '7) which are threaded into the bearing.

The crosshead. 92 which carries the counter holding means 80 and clamping means 82 is mounted for movement transversely of the applicator brushes I4 and I6 upon a pair of horizontally disposed parallel rods I90 (Figs. 1 and 4), the latter being supported, at their opposite ends on the rectangular frame I0. As illustrated in Fig. 1, a pair of posts I92 are formed integral with the frame If! at the front of the machine and have openings I94 therein for the reception of the front ends of the rods I99. The rear ends of the rods I98 are supported by a corresponding, pair of posts I86 which are formed integral with the rear end of the frame II] and have openings I93 for th reception of the rear ends of the rods. The transverse or linear sliding movement of the crosshead 92 along the rods ISii from front to rear is accomplished in a manner to be described below to move the counter from its initial position at the front of the machine, with its open end toward the rear, toward the applicator brushes with the upper leg disposed at an angle of about 20 to the horizontal. Linear movement of the crosshead with the counter in this position brings the aforesaid leg into contact with the brush I6 which applies a coating to the inside of the counter at a point back of its leading edge, as will beseen by reference to Fig. 9, since the leading edge and the marginal portion adjacent thereto, represented by the reference character m, pass above and beyond the brush without making contact with its surface as the counter is moved horizontally to the rear toward the brush. Hence, this marginal portion remains uncoated. After contact is made between th counter and the brush, the crosshead continues its linear movement until the brush engages the closed, rounded end of the counter, whereupon mean to be described causes rotation of the counter which brings the other leg of the counter into a position reversely inclined to that of the first leg of th counter, that is, so that the leg makes an angle of about 20 to the horizontal. After the rotation is completed, the crosshead resumes its linear movement and the second leg is drawn between the brushes and disengages the lower brush It at a point which precedes the trailing end of this second leg. Hence, a marginal portion on the second leg corresponding to the marginal portion m on the first leg is also left uncoated. During the coating of the inner surfaces of the legs, the outer surfaces are also coated, the upper brush It being moved up and down in timed relation with the movement of the counter so that contact is made with the first leg at a point spaced from the advancing end and substantially opposite to the contact of the brush It with the inner surface of the leg, and contact is broken, by raising the brush I4, at a corresponding point on the opposite leg. The mechanism for accomplishing the linear movement of the crosshead and the rotational movement of the counter support and clamping mean will now be described.

At the front end of the machine, upright posts (Figs. 1 and are mounted on the frame I0 and upon the upper ends of these posts are fixed inwardly extending horizontal studs 26?. and 204 (Fig. 7). Rotatable on the horizontal studs are pulleys 203. At the rear of the machine, a pair of sprockets 2 I2 are mounted on a level. with the 1.0 pulleys. 208 on a horizontally disposed shaft. 2 I4 (Fig. 1) which. is. journaled at. the upper ends of a pair of upright. posts 2I6 which rise vertically from the frame H1. The. aforementioned chains I06 and [8-8, as heretofore explained, are connected at their opposite. ends to the pulleys Hi0 and I84; attached to. the. counter holding and clamping means, respectively. Starting at these pulleys, the chains. pass over the top of the pulleys and are carried to. the left of the crosshead, as seen in Fig. l, and around. the pulleys Ziiii, thence lengthwise of the machine beneath the brush shafts, I8 and 20 and the sprockets 2I2 and back to the pulleys [U0- and I84. In order to keep the chains taut, the posts ZIJii at the forward end of th machine are pivotally supportedv at their lower end upon bolts 2 I 3 (Fig. 9) so that they may be moved forward or backward. Each post 203 is provided with an elongated slot 220 through which there is passed a clamp bolt 2.22 which serves to lock the posts in such a position that the chains are held in whatever degree of tautness is desired.

Upon the stud 202 at the front end of the machine there is fastened a bracket 224 (Figs. 7 and 9) which extends upwardly and inwardly from the post and has a horizontal arm 226 formed integral therewith through one end of which there is threaded a. rod 228 the position of which may be adjusted by turning it in the. arm 226 and looking it in place by a nut 236. At the end of the rod there is formed a yoke 232 in which there is journaled a stop-disk 234. As will be seen by reference to Fig. 5, the stop-disk 223i is adapted to engage the wedge-shaped block I14 when the cross-head is at its initial position at the front of the machine, thereby holding the counter clamping plates I30 away from the V- shaped block I26, and hence the operative may place the counter astride the V-shaped blocks I26 and 84. In placing the counter in position astride the aforesaid blocks, the inturned bottom flange 81 of the counter I9 is inserted in the groove 94 of the V-shaped block. 84 and the upper marginal edge of the counter is disposed along the sloping surface I28 of the V-shaped block l26, the operative pushing the counter forward into engagement with the blocks with sufficient force to move the rounded end I58 (Fig. 10) of the. V-shaped block I26, which is normally held away therefrom at this position, into engagement with the block and holds the counter thus until the machine is started and. the crosshead moves away from the stop-disk 234 far enough to permit the counter clamping plates I30 to come into engagement with the upper margins of the legs of the counter. To start the machine, the operative pulls forwardly a. rod 236 (Fig. 1), having a knob 238 for conveniently gripping it, and this, as will be seen by reference to Fig. 3, moves a bell-crank lever 246 in. a counterclockwise direction about a pivot 242. Alternatively, the rod 236 may be pulled forward by a chain 239 connected to the rod, as seen in Fig. 5, and to a treadle-operated lever 2M, the treadle being located below the machine but not shown herein. The lever 24!] is retained in this forward position so that the machine continues in operation once the rod 236 has been pulled, Without holding it, by a spring 243 stretched between the lever and the frame in a position to cross the center of the pivot 242, as explained in the prior appl cation, to bias the lever in one position or the other. A fork 244 (Fig. 3) is formed in the end of one arm of the lever 240 which co-operates with a pin 246, the latter being fixed to a horizontally disposed plate 248 which is slidable'widthwise of the machine upon a pair of rods 25!]. The rods 250 are journaled in spaced relation at their opposite ends in substantially triangular shaped upwardly extending webs 252 (Fig. 1) formed at the rear of the frame formed at their upper ends for pulleys which serve to connect the machine to a motor (not shown) placed near the base of the machine, as illustrated in the prior application. On the horizontal plate 238 there are a pair of belt shifters 256 and 258 which extend forwardly and rearwardly, respectively. A horizontal shaft 268 is journaled in the bearings 254 and has on it three

pulleys

262, 264, and 262. The middle one of these pulleys 264 is fastened to the shaft 260 and when rotated by a belt causes rotation. of the shaft 268 which, in turn, drives the shaft 2M by way of a pair of meshing gears 268 and 210, the former being fastened to the shaft 260 and the latter to the shaft 2M. The

pulleys

262 and 266 are free to turn on the shaft 260 andeach has a pair of grooves in its peripheral surface for reasons which appear in the prior application. A crossed belt 212 is carried by the pulley 282 and an open belt 274 is carried by the pulley 266. These belts, as will be seen by reference to the prior application, are connected to asource of power (notshown) and may be shifted by movement of the belt shifters 256 and 258 to drive the pulley 264 in a. counterclockwise or a clockwise direction and hence to move theupper run of the chains 16 and I88 either in a right-hand direction or a left-hand direction, thereby to re-. ciprocate the crosshead linearly with'respect to the applicator brushes. As explained in the prior application, the crosshead has projecting from its rearside a bolt 276 (Figs. 1 and 9-) which will engage the lever 240 as the crosshead moves to the extreme right-hand position automatically to ment of the machine and cause the-crosshead to return to the front of the machine. Hence, when the crosshead is initially started it will travel from the front end of the machine to the backend andthenreverseitself and travel back to the front end where it will automatically be brought toa stop by the following mechanism. At the front end of the crosshead and projecting downwardly from its underside isa boss 284 (Fig. 5) which, as the crosshead moves to its initial position, engages acollar 286 fastened to the rod 236 which pushes the rod forward a sufficient distance to move the lever 24d, and consequently the belt shifter, to a neutral position so that the machine comes to rest. Simultaneously, a latch 218 (Fig. 9), which is pivotally attached to the front end of the crosshead and is spring pressed. downwardly by a torsion spring 28!), engages a.

92 sothat it may be moved linearly by the chains mea er-.-

Iil, the webs having bearings 25d.

12 At one point in the linear movement of th crosshead, the counter support and the clamping means are rotated, as in the previous machine, when the rounded, closed end of the counter reaches the applicator brushes. This is accomplished, as in the prior machine, by a pair of levers 23B and 292 (Figs. 1, 6 and 9) which are pivotally fastened to the frame 10 at 294 and 295, the lower ends being urged toward each other by a spring 298 which is fastened between them. The upper ends of the levers bear on the underside of a horizontal bar 308 (Figs. 1 and 9), which is fastened to the crosshead and moves therewith, and are adapted to engage notches 392 formed in the underside of the bar. The

respective levers

293 and 292 have ofiset cam blocks 29l and 293 (Fig. 6). During movement of the crosshead toward the rear of the machine, that is, to the right as seen in Fig. 1, the lever 292 will engage the righthand notch 3G2 and arrest the linear movement, whereupon continued movement of the chains I and I88 will cause rotation of the counter holder and clamping means about the axis of the shaft H 3 until a stop screw 304 (Fig. 6) threaded through one of a pair of lugs 306 formed integral with the disk ms strikes the cam block 29! lever and pushes it down out of the notch 392, whereupon the crosshead will continue its linear movement to the rear of the machine. As in the prior machine, the movement of the counter holding and. clamping means during their approach to the brushes and after they have passed beyond the applicator brushes is restricted to linear movement by the frictional resistance to rotation of said holding and clamping means afforded by tightening the bolt I20 which draws the split bearing H6 about the shaft H4. When the lever 292 rises into the notch 3032 as the crosshead moves toward the center of the machine, the frictional resistance to rotation of the shaft I M in its bearing i "5 is overcome and rotation takes place until the lever 282 is moved out of the notch. 0n the reverse movement of the crosshead from the back of the machine to the front of the machine, that is, from right to left as seen in Fig. 1, the lever 298 performs a similar function so that the counter is again rotated as it passes the applicator brushes until a screw 305 pushes it down out of its notch.

3 is, the direction of movement of the counter. In

order to avoid displacement of the counter clamping and supporting means from this position when the wedge-shaped block H4 is brought into contact with the disk 234 at the front of the machine, a locating screw 308 is provided which is threaded through a boss 3) formed on the disk I58, as will be seen by reference to Fig. 6. The end of the 10- cating screw 308 is adapted to engage the top surface of the horizontal bar 380 and hence to hold "the counter clamping and supporting means in the proper position against any tendency to turn.

In the prior machine, the brush for applying paste to the outside of the counter was stationary. In the present machine, however, in order to revent the application of paste to the outside marginal portions of the curved ends of the legs of the counters, the upper brush I 4 is so mounted that it may be moved into and out of contact with the legs of the counter in timed relation with the. movement. of the counter transversely thereof,

13 To permit such movement, as heretofore described, the shaft I8 of the upper brush It is mounted in the sleeve bearing 22 (Fig. 4) which is tiltable to and from the lower brush I6 about the horizontal pivot 28. The movement of the brush I l to and from the brush I8 is controll d by the combination of the spring 34 and a cam 8i 2 (Fig. 9), the cam being fastened to the upper ends of a pair of vertical posts 3% which, in turn, are set into recesses formed in the sides of the post 'I I? on the crosshead 82, as seen by reference to Figs. 1 and 9, and held there by screws 3I5 (Fig. 1) and a through bolt 3H. As will be seen by reference to Fig. 4, th shaft I8 extends beyond the righthand side of the brush I 4 and has mounted thereon a collar 3H5 and a freely rotatable sleeve SIB which is held against the under surface of the cam 3I2 by the spring 3a which urges the bearing sleeve 22, and consequently the shaft I8 of the brush I4, in a counterclockwise direction about its pivot 28. The lower surface of the cam 3I2 is so shaped that when the crosshead is at its initial position that portion of its surface designated a (Fig. 1) holds the brush I l in engagement with the brush IS in opposition to the spring 34 so that the brush I6'will receive paste from the brush I2. When the machine is started, the cam 3I2 moves to the right, as seen in Fig. 1, and the sleeve 3I8 follows the upward slope of the surface marked 1) so that when the leading end of the counter is approximately adjacent to the entrance side of the brushes the upper brush I8 will have risen to the position shown in Fig. 9. Hence, the brush I i is separated from the brush I6 and it does not contact the leading end of the counter. At this position the sleeve 3 I8 occupies the portion 0 of the cam. Further movement of the crosshead brings the sleeve 3l8 into engagement with the downwardly sloping surface 11 of the cam so that the brush I 4 is brought into engagement with the outer surface of the counter and at the point e the brush IA is held in a fixed position during the rotation of the counter. As the other leg of the counter is withdrawn from between the brushes the brush I4 is allowed to rise out of contact with the counter, just as the trailing marginal portion of the leg reaches the brushes, by the sloping surface f. Since the cam surface is symmetrical, on the reverse movement of the crosshead the brush I4 is actuated in the same manner.

During the movement of the brush I4 to and from the brush IS, the paste container 42 is moved upwardly, to prevent undue pressure of the brush against the paste container during the rising movement of the brush M, by the co-operation of a cam roll 320 with that portion of the upper surface of the cam 3| 2 designated g. Before the counter engages the brushes, the brush I4 is in engagement with the brush I8 to feed paste to it and the container is held in a depressed position, to maintain contact with the brush, by a dip in the cam surface at h. The cam roll 32!] is freely pivoted on an arm 322 extending downwardly from the bottom side of the pivoted arm 46 upon which the container 42 rests. A fork 32! fastened to the bottom of the container engages the collar 3I6 on the shaft l8, guides the container as it moves up and down in accordance with the position of the cam, and keeps the arm 46 and shaft I8 in alinement.

At rest, the crosshead 82 is at the front of the machine, as shown in Fig, 1, being held in this position by the latch 218. In this position the counter clamping means I80 are held disen- 14 aged from the substantially v-sharped block I26 by the stop-disk .234, as represented in Fig. 5; hence, the machine is in readiness for receiving an uncoated counter to be operated upon. The counter is placed astride the counter holding and clamping blocks 84 and I28 and is pushed rearwardly to bring the spring-pressed rounded end I58 (Fig. 10) of the block I28 in engagement therewith. While the counter is held in this position, the operative pulls the rod 236 by means of the knob 238, or by the operation of a treadle connected to the lever 2M, which causes the collar 286 (Fig. 5) to lift the arm 288 thereby to release the latch 278. The rod 238 also shifts the drive belts, whereupon the crosshead begins to move toward the rear of the machine. As the crosshead leaves its initial position, the wedge block Il l disengages the stop disk 234, allowing the clamping plates I38 to be drawn by the springs I82, I84 into clamping position to hold the counter in place. During the initial movement of the crosshead the portion a (Fig. 9) of the overhead cam 3I2 holds the brush I4 in engagement with the brush I8 and the receptacle 42 in engagement with the brush I l, thus supplying both brushes. The counter holding and clamping means approaches the brushes, holding the counter with one leg at substantially 20 to the horizontal and as the leading end of the leg approaches the entrance side of the brushes the cam 3I2 moves the upper brush I I away from the lower brush I8. Hence, the leading end of the leg of the counter enters between the brushes without engaging either of them. As the linear movement continues, the inner surface of the leg engages the brush I6 and simultaneously the cam depresses the brush it so that it engages the outer surface of the leg. Since the leg slopes, the cam 3 I2 is so formed that the brush I4 is moved downwardly to follow the slope of the leg during the remainder of the movement of the counter until the rounded end thereof is reached, whereupon it is held stationary. Rotation of the counter is effected by the lever 292 which arrests the linear movement of the crosshead until the other leg of the counter is brought into a reversely inclined position, that is, so that it makes an angle 20 to the horizontal, whereupon the screw 384 on the disk I88 (Fig. 6) releases the lever 292 and linear movement is resumed, thus drawing the other leg between the brushes. During this period the brush I4 is moved upward y along the slope of the other leg and out of engagement with the other leg near its end portion simultaneously with the movement of the inside of the leg out of engagement with th brush I6. The crosshead continues its movement to the rear of the machine where the bolt 218 (Figs. 1 and 9) on the crosshead base strikes the lever 248 and shifts the drive belts, reversing the direction of movement of the chains I86 and I88 so that the crosshead is moved back toward the front of the machine in the same manner that it moved toward the rear of the machine. Near the front of the machine the depending boss 284 (Fig. 5) on the crosshead strikes the collar 288 and thereby moves the rod 288 which, in turn, moves the lever 248 to a neutral position, thereby stopping the machine. The latch 218 also rides over the pin 282 to hold the crosshead in rest position. At the same time, the stop-disk 234 strikes the wedge block I14 and disengages the clamping means I38, whereupon the rounded end I58 of the block I28 disengages the counter from the counter supporting 15' and clamping blocks 84 and H6. This completes the cycle of operation of the machine until the rod 235 is again actuated.
