MACHINE FOR OPERATNG ON SHOE COUNTERS.

Application led July 21,

This invention relates to machines for use in the manufacture of shoe counters and the like. The invention isespecially concerned with the problem of tempering fibre counter blanks prior to being molded although it will readily be appreciated from an understanding of the invention that some of its features may also be used to advantage in other machines for operating on counters or counter blanks.

The usual process of manufacturing a molded fibre counter consists, brieliy stated, in shaping the counter blank, tempering the blank, and molding it. That is, the blank is cut out of a. sheet of fibre board, the edges are bevelled, the ends usually are .released7 or ski ved. and the blank is next tempered or moistened preparatory to being molded. This tempering operation is designed to make the blank more pliable so that it will not break during the molding operation, and also to enable it to take the shape of the molds more readily and to permanently retain this shape.

According to the usual practice these blanks are tempered by dipping them in Water, a stack of the blanks usually being dipped simultaneously by hand. They are then allowed to `remain in a stacked or collected condition for several hours so that the water will penetrate the stock. It is important that the blanks shall neither be too wet not too dry at the time the molding operation is performed andone of the import-ant difficulties in carrying out this process is to control the degree of moisture, or in other words, the degree of temper. That is, in the usual hand process some of the counter blanks are very likely to receive much more water than others, with the result that when the majorityv of the blanks are in the proper condition for molding,

' others in the same batch are either too wet or too dry. Y

Vf ith these conditions in view it is the chief object of the present invention todevise a machine which will automatically perform the tempering operation. The invention aims not only to devise a satisfactory tempering or conditioning mechanism, but also to devise SimpleV and reliable. mechanisms for feeding' the blanks to the tempering` or conditioning means and for automatically stacking the blanks after they have been tempered or conditioned. It is con- 1921. serial No. 486,452.

templated that the feeding and stacking mechanisms can be used to advantage in other machines for operating on counter blanks and they like, as forinstance, in machines for printing the blanks, bevelling or releasing them, or otherwise modifying their condition.

The nature of the invention will be readily understood from the following description when read in connection with the accompanying drawings, and the novel features will be particularly pointed out in the appended claims. v v

Referring now to the drawings,

Fig. 8 is a rear elevation of a portion of the magazine for the counter blanks and the mechanism for feeding the same, certain of the part-s being shown in cross sec.- tion; and

Fig. 9 is a vertical cross-sectionalview of part of this mechanism.

The machineshown comprises foui1 tempering rolls arranged inpairs, the upper and lower rolls of one pair being designated by the numerals 2 and 3, respectively, and those of the other pair by the numerals t and 5. rhese rolls preferably have rubber vsurfaces and they are provided lwith extensions or shafts which are supported in bearing blocks, certain of these blocks being indicated by the numeral 6, Fig. 3. These blocks are supported in verticaljguideways 7 7 formed in bearing brackets 8 8, Figs. l and, which are secured to the bed or base l0 of the machine. Cap plates 9 9 bolted to the upper edge of the bearing blocks 8 8 close the upper ends of the slots 7 7.

The construction at one end of the rolls is and form the bottom of the magazine these plates being supported by adjusting screws 51, Figy2, which are threaded into the plate 37 and serve as a convenient means for adjusting the level of the plates 50.

As shown in Fig. 1, the bottom of the magazine is divided into three parts, the central part being spaced from the members at opposite sides thereof by slots in which two conveyor belts or chains 53 53 are located. rllhese chains are supported on front and rear pairs of sprocket wheels designated at 54 and 55, Fig. 2, mounted, respectively, on shafts 56 and 57 supported in the opposite side pieces 36-36. A gear indicated diagrammatically at 58, Fig. 2, is mounted fast on the shaft 56 and is driven through

additional gears

59, 60 and 61, the last of these gears being mounted fast on a shaft 62, Figs. 1 and 2, which is supported in bearings 63-63 secured to the base 10. This shaft is driven through

bevel gears

64 and 65, Fig. 1, the latter gear being mounted fast on the end of the shaft which supports the roll 2.

This mechanism imparts a Continous motion to the chains 53-53 and it will be seen that each of these chains carries at interval-s a feeding link 66, the construction of which is best shown in Fig. 5. The upper surface of each of these links includes a straight horizontal portion 67, an upwardly inclined portion 68, and a hook or tooth 69 located at the upper end ofthe inclined portion 68. The rearward edges of the counter C are bevelled and as the upper reach of each chain 53 moves forward and one of the links 66 comes in contact with the bevelled edge of the `bottommost counter blankl in the stack, the edge of this blank will ride up on the incline 68 and be caught by the hook or tooth 69. This construction ensures the accurate engagement of each blank by the` hooks 69, notwithstanding slight bends or irregularities inthe shape of the blanks. These feeding teeth 66 are so spaced on the two chains 53-53 that the corresponding hooks of each chain will simultaneously engage the rearward edge of a counter, and as the chains continue to move forward these hooks will carry the lowermost counter blank out from under the other blanks in the stack, the next adjacent blank being prevented from moving with the lowermost blank by it contact with the friction members 52-52 of the gates 49-49. That is, the bar 38 is adjusted so that the lower edges of the parts 52 are normally just above the surface of the plates 50, leaving a slot only wide enough to permit the entrance of the bevelled edge of the lowermost blank. As this blank is carried forward by the hooks 69h69 the contact of the inclined edge cf this blank with the parts 52-52 lifts the gatos .t9-i9 slightly, this movement; permitting the lowermost blank t0 be carried forward out of the magazine. As soon as the blank has passed out from under the gates they can drop by gravity into their original positions. This mechanism thus operates with great certainty to prevent the feeding of more than one blank at a time.

When the lowermost blank in the magazine has been fed forward, as above described, itis delivered by the conveyor chains 53-53 to upper and lower feed rolls 71 and 72, respectively. The upper roll is in two sections, both fast on a shaft 73, while the lower roll is secured fast to a shaft 74 having a gear wheel 75 fixed thereto which is driven through a train of gears indicated at

l

76, 77 and 78, Fig. 2, the last of these gears being fast on a shaft 79 having a gear 8O fiXed thereto which meshes with another gear 81 mounted fast on the sprocket wheel shaft 56. in order to allow the upper feed roll 71 to move up and down relatively to its cooperating lower roll 72, the` shaft 73 is mounted in the upper ends of two inclined links, one of which is shown at 83, Fig. 1, this link being pivoted on a bolt 85. The other link is similarly arranged. A pinion 7 5a is secured fast to the vshaft 73 and is driven by a gear fixed to the shaft 56. The feed rolls 71 and 72 revolve at a greater peripheral speed than the chains 53 and they take the counter blank out of the hooks 69 and shoot itl forward on to a supporting surface 90, Fig. 2,'formed partly on an upright plate 91 and partly on a bracket 92 bolted to said plate. This prevents the hooks from notching the rearward edges of the blanks. ln Fig. 2, C designates counter resting on this support. A shield 93 secured fast to the plate 91 overlies the portion of the surface 90 on which the counter is delivered and prevents the counters from being thrown over the upper edge ef the plate '91. A conveyor carries these counters forward and delivers them to the wetting or tempering rolls previously described. rEhis conveyor consists of a sprocket charL 94tprovided with feeding teeth 95 of the shape best shown in 3, this chain being supported on sprocket wheels 96 and 97 mounted near the opposite ends of the upright plate 91, and the upper reach of the chain runs in a groove 98, Fig. 2, formed in the bracket 92. The sprocket wheel 97 is mounted fast'on the end of a shaft 99 supported in bearings formed in a bracket 100, and this shaft'also has fixed to its opposite end a gear 101, Figs. 1 and l, which meshes with an idler gear 102 that is driven by the barrel pinion 26 previously referred to. lhis mechanism thus imparts a continuous nieve` ment to the chain 9a, ann-the driving mechanism for this chain is positively connected with the driving mechanism fcr the feeding chains .5S-53. The movements of these two chain-sare so timed that the conveyor 91 :car-vv ries the counter'blanks forward and delivers them to thewettmg'rolls asl rapidlyv as: theA chains' feed the blanks-out of the magazine.

The upright conveyor chain Silvie secured 'tast to the Jforward end ot aslide 1011, Fig. 1, whichl is mounted in a dove-tail groove formed in the bed plate 10. secured to, .or 'formed integral with, slide 10h/l.

A .bolt 107 which project-s through a slot 108 `formed in the-slide 10e-and is threaded into the bed 10, serves to secure the plateinits adjustedA position. A. shortbracket 109, 'l3`ig.i2, isrsecuredrto the front of the magazine frame and overlies: a portion ot' the bracket92zwh'ere vit closes` the space between the magazine frame .and the second conveyor mechanism,. and prevents counter blanks from dropping down between'these-parts.

parts

105 and 106.

The table 112 also is adjustable With reference to the bracket 114 at right angles to the adjustment above described. That is, this table is provided With a

tongue

153,11`igs. 3 and 6, that projects into a groove formed in the upper surface of the bracket 144, vand the table is slotted, as shown at 154, F ig. 1, tov4 receive a bolt 155 by means ofWhich it is secured in its adjusted relationship to the bracket 144.

An arm 156, F ig. 7, projecting from a portion of the bed 10, supports the outer end of the extension 144 but this part may be supported in any other suitable manner. The adjustments permit the stacking mechanism to be moved into any desired relationship to the tempering mechanism.

1t Will noW be understood that during the normal operation of the machine the feeding chains 5353 remove counter blanks one at f a time from the bottom of the magazine, ad-

' 113 of the table 112.

vancing these counters, in this vparticular instance with their straight edges foremost, against the edge of the part 91. @ne of the hooks 95 on the conveyor chain 94 engages each blank and carries it endyvise to the tempering rolls 2 to 6 inclusive. The blank here is dampened, the tempering rolls present it to the rolls 15 and v16, and these rolls deliver the blank to the inclined surface The stacker lever 117 moves this blank up into an approximately upright position on the table and these operations are repeated so long as the machine runs, the tempered blanks being forced outwardly along the extension 114 of the table.

It Will therefore be appreciated that this invention provides a completely automatic machine for taking blanks from al stack or supply, tempering them, and stacking them in readiness to be removed by an attendant. The machine thus reduces very greatly the labor that otherwise Would be required to perform the tempering operation, and it produces superior results since the tempering of the blanks is substantially uniform. It Will also be appreciated that the stacking and feeding mechanisms can be used in vother machines than that specifically disify their condition, mechanisml for feeding blanks successively from said supply to said operating means, a slightly inclined support, and means for receiving the blanks thereon as they are discharged from said operating means and subsequently stacking them upon edge.
