PATTERN-BIN DING MACHINE.

Application filed March 30, 1923-. Serial No. 628,814.

To all whom it may concern:

Be it known that we, J oHN H. SU'rHEn- LAND and HOLTON J. SUTH'ERLAND, citizens of the United States, residing at Swamp,-

setts, have invented a certain new and useful Improvement in Pattern-Binding Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to a, new and useful improvement in pattern binding machines. It relates to that type of such machines employed in applying a metal binding along the edge ,of flat patterns of various kinds, and is especially adapted for use in connection'with boot and shoe patterns.

The present application is an improvement on the machine'shown and described in Letters Patent No. 1,135,469, granted to said H. J. and J. H. Sutherland, April 13, 1915. i

In the machine shown in said patent, the pattern with the binding started on the edge of the pattern is fed between two presser rolls, one of which is movable toward and from the other roll, and the-binding is pinched 'onto the pattern as it passes between the rolls. There is also provided a back stop against whichthe base of the U-shaped folded binding engages while the pattern andbinfding are passed between the rolls so as to hold the binding in proper relation to the pattern. The stop is preferably mounted on a turret on which are mounted a plurality of stops of varying sizes and shapes, said turret being adjustable on its axis so that one stop or another may be brought into operative position, as desired. Some of these stops consist of rolls and the said rolls are rotatable on their axes to prevent friction. One feature of the present invention consists in providing a positive feed connectionbetween the lower presser roll and the turret mounted roll, so that the presser roll and the turret roll shall have the same peripheral speed. 7

Another feature consists in forming the two presser rolls with short peripheral teeth which engage the pattern, each of said teeth being disposed diagonally of the periphery of the roll, the teeth being arranged so that the lines of the. teeth on the two rolls are divergent on, the side toward the inner face insucfh manner as to at all times force the edge of the pattern and the binding thereon up against the stop roll or turret roll.

Another feature of the invention consists in providing an. eccentric mount for the turret, so that the turret roll-may be positioned either on, or off center, as desired, with relation to t-heaXiS, of the presser roll. Another feature relates-to the means for holding the turret in its adjusted position on its axis. Another feature relates to the means for raising the upper presser roll for the purpose of removing andinse'rt-ing' the work, and consists in providing means by which a slight backward turn of] the crank after the machine. has stopped will liftthe upper roll. Another feature relates to the mounting for the former block, so that it can be readily shifted to different positions. Other fea tures will be apparent from the following description of the invention, the novel fea tures of which will beclearly understood lOIl1: said description when taken in con nection with the accompanying drawings, and will be clearly pointed out and defined in. the claims at the close of the specifica tion.

Fig. 10 is a detail sectional view of the clutch shown in Figs. 1 and 3.

Fig. 11 is a section on line 11 of Fig. 1, showing the method of mounting the, upper shaft. 7

a 7 rigidly connected a head 3. From this head extend back i over the base the two horizontal arms 4,

5, respectively, which form supports for the several operating parts of the machine.

A shaft 6 is journalled at one end in the head 3 and at its other end in the bearing with the horizontal arm 4s. The said shaft extends through said bearing and has mounted thereon a turret 8 and a presser roll 9, the presser roll 9 being fast on the shaft so as to rotate therewith and the shaft passing loosely through the turret which is held from rotation.

A shaft 10' is journalled at one end in the head 3 and at its other end in a bearing 11, which is hung by a link 12 from a rocking lever 13 pivoted at 14:, so that said lever may be rockedon its pivot to raise the bearing 11 and thereby, when desired, lift the forward end of the shaft 10. The rear end of said lever 13 is connected with a vertical rod 15 which passes down through an apertured guide 16, the lower end of'said rod 15 being connected with a treadle 17,

which may be operated by the foot to turn the lever 13 on its fulcrum and thereby lift the movable end of the shaft 10, when desired.

Other means are also provided, which will be hereinafter described, whereby the said shaft may be lifted by turning the crank backwards. .7,

On the other end of the shaft 10 there is mounted a presser roll 18 to cooperate with the presser roll 9 for pinching the binding onto the pattern. It is important that the two presser rolls should be at all times maintained out of contact with each other, being spaced apart just enough to allow for the roper pressure, according to the thickness of the binding and pattern.

The bearing 11, which supports the outer end of the shaft 10, is engaged by a spring 19, one end of which is secured to the upper arm 5 by a bolt 20, the other end resting under tension upon the upper end of the bearing block 11. In order to limit the downward movement, however, of the said bearing block 11, a collar 22 is mounted on the rod 15, the upper end of said collar normally resting against a shoulder 23 formed on the head at the lower end of the guide 16 through which the rod 15 extends. Said collar 22 is adjustable by means of a set screw 24 so as to vary the adjustment and thereby regulate the limit of the downward position of the free end of the shaft 10 and of the pressure of the presser roll 18.

The shaft 6 is provided with a crank, 25 for rotating the same, and on said shaft is mounted a gear 26 which engages with a gear 27 mounted on the upper shaft 10,

whereby the rotation of the shaft 6'by the crank will also cause the rotation of the shaft 10 and the rotation of the two presser rolls 9 and 18. r

The gears 26 and 27 have a slightly greater clearance between them than is usual with gears of this type, to allow for movement of the upper shaft 10 when said shaft is pilpped axially by the lever 13.

l eans are provided for regulating the tension of the spring 19. The means provided are as follows: A screw 28 passes down through a block 29 mounted on the upwardly extending side flanges of the upper arm 5, its lower end engaging with the upper face of the spring 19, said screw having a knurled head 30 to operate the said screw. By turning said screw the pressure of the screw on the spring 19 will be varied, thereby varying the tension of the spring. A lock nut 31 is provided for the said screw, which rests upon the upper side of the block 29.

As already stated, the pattern, as indicated at 32, is fedbetween the two presser rolls 9, 18 to pinch the binding 33thereon, and, as already stated, it is important to have a stop for the'base of the binding and for the edge of the pattern, so that they will not be pushed too far in and also to serve as 'a guide. In order to provide a variety of stop members, the turret 8 is rotatably adjustable.

As shown in Fig. 7, this turret has provision for four different stops arranged apart on the periphery of the turret. These stops are shown at 341, 35,36 and 37 The stops 34,35 and 37 are shown as rollers of different sizes. The stop 36 as indicated in Fig. 1 is shown as a thin blade, the blade being specially used for binding in slots. These stop members 3 1, 35 and 37 are all mounted on pivots 48, so that'they can turn on their axes when in operative position during the feed of the pattern and binding. In the drawings, the roll 34 is the one shown in operative position in the machine. In the form of machine shown in Patent No. 1,135,469, previously referred to, these rolls were turned only by their frictional engage ment with the base of the binding and were not positively rotated. One object of the present invention is to provide positive 7 means for rotating'said stop rolls in unison with the rotation of the presser'rolls. To that end the rolls 3-1, 35 and 37 are provided with teeth 38 and the inner face of the lower presser roll 9 is formed with teeth 39, which engage with the teeth 38 and therefore'canse a positive rotation of said stop rolls as the shaft rotates.

It is also desirable to provide means to force the pattern with the applied binding against the stop roll. As heretofore made, the binding on the pattern is held against the stop roll by the hand of the operative while" the pattern and binding are passing between the presser rolls, and the operative has to be especially careful that he always maintains the pattern and the binding in proper alignment and engaging position with the stop roll. Sometimes, however, there is a tendency for the pattern to slip away, either due to carelessness of the operative or otherwise, and it therefore sometimes happens that although the binding may be kept against this stop roll the pattern may slip out a little, and this leaves a little space between the base of the binding and the edge of the pattern, whereas the base of the binding should be in con tact with the edge of the pattern at all places. In order to aid in overcoming this danger, I provide means by which there is a constant feed pressure on the pattern to force it up against the stop roll. To this end 1' form knurled or toothed surfaces and 41, respectively, on the periphery of the upper and lower presser rolls, these knurls being in the form of shallow teeth extending diagonally across a portion of the width of the periphery, as shown in Fig. 6. Itfis essential that the teeth slant in a certain direction in relation to the travel of the pattern, and to this end the teeth on the lower roll converge with relation to the teeth on the upper roll toward the outer side as viewed in elevation, so that the effect of such construction is to force the pattern inwardlytoward the stop roll 34 and to press the binding 33 up against the stop roll, while'the edge-of the pattern is firmly set against the inner face of the base of the binding.

Sometimes it is desired to have the stop roll or turret roll so positioned that the axis of the roll is centered with relation to the axis of the two presser rolls and sometimes it is desired to have the roll somewhatoff center. In Fig. 5 of the drawings, the roll is shown as off center and in Fig. 9 it is shown as positioned on the center. Usually it is desired to have it off center. The off center arrangement practically results in making the base of the U-shaped binding convex instead of flat.

Means are provided whereby it may be easily adjusted either on cente'r'or off cen ter within limitedrange. The means which we have provided for this adjustment is as follows:

The turret 8 instead of being mounted directly on the lower shaft 6yis mounted on an eccentric bushing 42, the turret being formed with acircula'r opening 43 which fits over the periphery of the eccentric 42.

Said eccentric is adjustably mounted in the frame of the machine and to this end is provided with a hub 21 (see particularly Figs. 1 and 4) which is mounted in the bearing portion 7 of said frame.

It is also formed with an are shaped slot 44 which is engaged by a pin or screw 45 projecting from and in threaded engagement with said frame. By partially rotating the eccentric on its axis it may be adjusted to different positions within the limits allowed by the slot 44 and is then clamped in its adjusted position by setting up the pin 45 so that its head 46 will bind. It is obvious that by varying the position of the eccentric on its axis, the position of the turret will be changed so that the turret will be either centered with relation to the two presser rolls or be thrown off center at varying positions as desired, thereby var ing the position of the particular stop roll which is in operative position at the time. By loosening the screw 45 the eccentric may be readjusted, thereby readjust-ing the turret and then by setting up the screw the turret will be clamped in the adjusted position.

We provide means for positively locking the turret in its adjusted position so that it cannot rotate accidentally after it has been adjusted. To this end the turret is formed with four flat faces 47, 90 apart into which are set the several pins 48 on which the several turret or stop rolls are mounted. A clamping screw 52is provided with a broad head or cap 58 which extends over and bears against one of the flat faces of the turret so that when said screw is set up with the head of the screw bearing firmly against the flat face of the turret, said turret cannot be rotated.

lVe have hereinbefore described the tipping of the upper shaft 10 at its rear end so as to raise and lower the forward end and the upper presser roll by means of a treadle and a connecting rod 15.

It is found in practice that it is a good deal of strain on the operator to keep the foot constantly on the treadle which is necessary when it is operated by means of the foot, owing to the frequent necessity for raising and lowering said upper presser roll, and we have, therefore, provided means whereby said presser roll and its shaft may be tipped by a slight backward turn of the crank 25 and consequent slight backward rotation of the shaft.

The means whereby the upper shaft may be tipped by means of the crank, is as follows:

The upper shaft 10 is extended through the upper gear wheel 2'? and on this exteir sion is mounted a clutch, preferably one commonly termed the Horton clutch, which operates as follows: Mounted fast on said shaft is a disk 54 which fits loosely within the flanged rim of a shell 55. Said disk 5a is formed with a series of peripheral notches 56, which together with the shell form pockets in which are held balls 57 seated upon springs 58. Projecting from the rim of the shell 55 is an arm 59. A connecting rod 60 engages loosely with said arm 59, at one end, and at its other end it is loosely connected with an extension 61 on the lever 13, as shown in Figs. 1 and 3.

When the crank is turned in the ordinary direction for operating the machine, that is, in a clockwise direction, as viewed in Fig. 3, the disk 54 will rotate with the shaft 10 in the direction of the arrow in said figure and there will be no driving connection between the said disk 5% and the shell 55. When, however, the crank is turned in the reverse direction, the balls 57 will become wedged into the tapering ends of the slots 56 and therefore bind the shell 55 to the disk 54, consequently causing the shell 55 to rotate during the backward rotation of the crank. This will cause the arm 59 to move backwards as viewed in Figs. 3 and 10, thereby pulling down the connecting rod 60 and the rear end of the lever 61 and lever 13, and tipping up the forward end of the upper shaft 10 so as to lift the upper presser roll the same way as when the lever is tilted by the foot pedal.

In order to permit the said shaft 10 to be tipped up in the manner already described, the rear bearing for the same is mounted on 'trunnions (see Fig. 11). The said bearing consists of a block 81 having trunnions 62 which are journalled in bearings 63 in the head 3 of the frame.

The shafts 6 and '10, respectively, preferably have mounted on the end toward the head, collars (i l and 65, respectively, which bear against the head of the frame and may be adjusted axially of the shaft so as to prevent endwise movement of the shaft.

Where the binding has to follow the contour of an indentation such, for example, as shown in Fig. 12, or any other substantial change in the contour, the binding must be shaped before it is applied. In order to provide a former adapted forshaping the binding to the contour of indentations'of various sizes, a forming block 69 is provided having different sections or portions thereof of different diameters so as to provide for curves of varying sizes.

It is important that the operative should have the forming block always convenient of access, and some operatives find it convenient to have it nearer to the presser rolls than others, owing to the difference in the size of the hands and other physical differences in the operative. To this end an adjustable mount is provided so that the forming block may be shifted according to the requirements ofthe operative: If itis too near it will be in his way during his work and liable to result in danger to his hands; on the other hand, if it is too far away there is too much loss of time. To this end there is provided a holder 67 connected with the outer end of the base 1 of the machine, said holder being formed with a plurality of sockets 68 ina line parallel with each other, so that some of them are nearer to the position directly beneath the presser rolls than are the others. The forming block 69 which contains a series of forming members of varying sizes all rigidly connected with the said former, is provided with a bore by which it is mounted upon a spindle 70, said spindle having a collar 71 on which said forming block is seated, and the lower end of said spindle is adapted to be received into any of the sockets 68 in the holder 67. If the operative wishes to have the forming block nearer to or farther from the work he has simply to lift the spindle out of one of the sockets and insert it into another one of the sockets, and clamp it in its adjusted posi a tion, if he desires, by means of a thumb screw 72.
