Referring by numerals tothe accompanying drawings, 10 indicates a support comprising a pair of side frames ll connected together by a plurality of transverse members 12. Each frame H is formed at its upper end with an outwardly presented horizontal flange l4 and an inwardly disposedhorizontal flange IS. The inwardly disposed flanges l are disposed on a'horizontal plane below the plane of flanges l4 and resting on the latter and projecting inwardly therefrom Thus a horizontally disposed track 'or groove I! is formed in the inner end of each frame H. Engaging saidgrooves are the horizontally and outwardly projecting flanges 18 of a carriage 19 which is thus slidably supported between said side frames H and is movable in a horizontal planelongitudinally of the machine.
Atable 20 is mounted on support It! by means of' 'transverse cross'members-2l above said carriage 19. This table terminates short of the forward end of support ID as indicated at 20a.
. i A' horizontally-and transversely disposed rod 22. is arranged between side frames H a suitable distance below and forwardly of the end 20a and fixed to said rod is a guide 24 which is substantially of the same width as said table. This guide is disposed obliquely and is curved at its ends and serves to guide a strip of canvasA on to said table. This canvas is arranged in suitable rolls B and is supported by means of a rod 25 between a pair of brackets 26 which are fixed to side frames H and extend forwardly, as shown in Figure 1.
Each canvas strip A extends from roll B upwardly over guide 24 and then horizontally over table.20 and the outer end of said strip terminates flush with the end 20b of table 20.
As shown in the drawings, the machine is made to receive two rolls B of canvas so that two inner soles can be operated upon at one time. Each inner sole D is provided with a'channel E which is spaced from the-heel portion F as indicated at G. The inner sole is laid on each, canvas strip with the channelE presented downwardly against said canvas and is attachedthereto by a suitable cement. Preferably this cement is applied to the inner ole immediately before the latter is placed on the canvas. However, if desired, the cement G of the channel Ealways coincide.
The knife 2'! is arranged horizontally and transversely adjacent to the end 20b of table 20. Said knife is fixed to a vertically disposed plate 28 which is mounted for slidable movement in vertical plane in the ends of frame H by means of guides 29. Knife 21 is secured to said plate 28 by screws 30. This knife is movable upwardly to cut a canvas portion when the latter is moved past said knife.
A bar 3i is fixed to the inner side of knife 21, preferably by screws 30, a suitable distance below the cutting edge of said knife. A plurality of upwardly projecting pins 32 is fixed to the upper side of bar 3| in spaced-apart relationship. End 2012 of table 20 is provided with a plurality of spacedapart semi-circular notches which are arranged {concentrically with said pins and provide clearance through which said pins move upwardly with said knife 21"and engage the outer end of said canvas and hold it against displacement.
The plate 28 isactuated through the medium ofconnecting links34' which are pivotally connected at their upper ends to the lower end of said plate, as indicated at 35, and at their lower ends to the outer ends of rock arms 36, as indicated at 37. Preferably each link 34 is adjustable to regulate the distance between the points of pivota'l'connection thereof. Arms 36 are fixed on a rock shaft 38 which is journaled in bearings 39 formed in side frames l I. This shaft is actuated in a manner hereinafter more fully described.
The carriage I9 is disposed below table 20 and moves longitudinally thereof from its normal po sition shown in Figure 2 toward the table end 291) and the vertically movable knife 21. An extension 40 projects upwardly from the carriage between each side piece l6 and the corresponding side edge of the table. A horizontally and transversely disposed bar 4| is fixed at its ends to said extensions 40 by screws 42. This bar is spaced a suitable distance above table 20 and carries a pair of knives 44 which are pivotally mountedthereon, as indicated at 45, and have their cutting edges spaced from said table. Each knife is engaged by a yielding spring 45 which yieldably holds the knife in an outwardly and oblique position which permits said knife to move against said bar 4| and assume upright position when pressure is applied to the outer surface of said knife as when it engages the toe edge of the sole when the latter is placed on the table. The cutting edge of knife 44 is'arranged in the same vertical plane with the outer face thereof and a comb 41 is fixed in the oblique edge of the knife in spaced relation with said cutting edge. This comb is provided with a plurality of teeth or prongs 48 which are presented downwardly.
When the knife 44 occupies normal or oblique position (see Fig. said prongs 48 are disposed above the canvas in spaced relation therewith. When, however, knife'44 is moved toward bar 4 I, as when said knife strikes the toe portion of a sole placed on the table, said prongs engage said canvas and pull it over the table simultaneously with the movement of the carriage while the inner sole and that portion of the canvas located between the carriage and knife 21 is also moved by virtue of the engagement of knife 44 with the toe portion of said inner sole. Just before the inner sole and the canvas strip are moved by the carriage. knife 21 and pins 32 are lowered below the horizontal plane of the table in order not to impede the progress of said canvas strip and said inner sole past the vertical plane of movement of said knife 21.
When carriage 19 reaches its outermost posiframe I l'.
the parts to normal position (shown in Figure 12) whereupon the outer end of arm 86, during its cycle of movement, is brought against said arm 90a'and is caused thereby to move against stop 88,
- thereby disengaging the clutch members from each other and rendering disk 63 stationary.
.The inner end 84a of pin 84 extends inwardly toward sprocket wheel 12 and past clutch member 83. Said arm is partially cut away, as in- "dicated at 84b, so as to provide clearance betweenit and the inner face 83a of ring 83. This ring is provided with a plurality of spaced semicircularnotches 83b which are substantially of the same radius as the radius of pin 84. When the treadle is not actuated, the parts occupy position shown in Figure 12 and the pin occupies position shown in Figure 14. In this position the pin,'by virtue of. itscut-away portion 84b, clears ring 93'as indicated by line X.X in said figure. Thus'the sprocket wheel I2. is free to operate without affecting cam disk 63. When the treadle is depressed, bell crank 90 is moved out of engagement with arm 86 so that the latter can move downwardly against stop 81 by virtue of spring 89. This movement of arm 86 causes partial rotation of pin 84, as indicated by line 'Y-Y in Figure 15, whereupon said pin is moved into the path of one of the circular notches 83b of ring 83 and the parts become interengaged, thereby actuating disk 63. If the treadle is now released, disk 63 continues to move to complete thecycle' of its movement and just before the :54 is held against longitudinal movement by collars 96 fixed on said shaft adjacent to each end of said arm.
Where the soles are sprayed with rubber cement, preferably a rack 91 is arranged to one side of the machine to hold a supply of inner soles. A'hood 98 is disposed to one side of said rack and a spray gun, suchas 99, is arranged in said hood (see Fig. 20). The operator stands on the treadle side of the machine and with his left hand takes an inner sole from rack 91' and holds it in the hood so that the channeled face thereof is sprayed from the gun 99 which may be held or controlled by the right hand of the operator. When the inner sole is sprayed it is laid on the strip of canvas disposed on table 20 with the channel or sprayed side against the canvas and with the channeled ends G abutting the knife 21 so that the heel portion F extends over said knife, as shown in dotted lines in Figure 2.
The operator now sets the machine in operation by depressing treadle 8|. This throws in engagement sprocket wheel 13 and disk 63 whereupon, oscillatory arm 52 and rocking arms 36 are operated. Arms 36 cause knife 21 and pins 32 to disappear below the horizontal plane of table 20 and arm 52 moves carriage l9 forwardly. During this forward movement of the carriage, knife 41 is brought in contact with the toe portion of inner sole D causing the latter and the canvas strip A attached thereto to move forwardly or toward shelf 49.
When the carriage I 9 reaches the end of its forward movement, knife 44 is disposed in a vertical plane with knife 21 and the inner sole D is arranged wholly to one side thereof or on shelf 49. Arms 36 are now moved upwardly (by virtue of cam race 63a and arm 11), thereby causing knife 2'! to move against knife 44 and sever the canvas strip on line HH or flush with the toe portion of said inner sole so that the latter can be removed with the severed portion of the strip attached to the channel face thereof.
The carriage then moves rearwardly to its home position, whereupon the driving connection between sprocket wheel 13 and cam disk 63 is disconnected by the arm 86 striking the upper end of hell crank 98 so that the pin 84 is actuated or partially rotated to move the end 84a thereof out of engagement with the clutch ring 83.
The strip A extends over the table 20 and terminates adjacent to knife 21. The latter forms a stop or guide against which the ends G of the channelE are placed when the inner sole D is placed on the canvas strip. While the distance traveled by carriage I9 is fixed, the strip is not moved or pulled until said carriage engages the toe portion of the inner sole so that the strip is always moved over the table only the distance equivalent to the distance between the toe portion of the inner sole and the arms G of the channel E. In this manner the canvas strip is always out accurately in accordance with the length of the channel portion and no adjustment of the machine is necessary when operating upon inner soles of different lengths. Thus inner soles of various lengths can be placed on table 20 interchangeablyand the machine automatically cuts the canvas into sections of corresponding lengths.
The machine is one simple construction, does not require experienced workmen to operate it, and is quick and eflicient in performing its intended functions.
