LEWIS 3'. BAZZONI, OF SWAMPSCOTT, MASSACHUSETTS, ASSIGNOR T0 UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEVJ JERSEY, A CORPORATION, OF 'NEW JERSEY.

Application filed September To all whom it mag concern:

Be it known that I, LEWIS J. BAzzoNI, a citizen of the United States, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented certain Improvements in Machines for Marking Shoe Uppers, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machies for marking parts such as shoe uppers, and, more particularly, to machines for placing indicating marks uponthe material to-designate locations for subsequent operations. The invention may be utilized with particular advantage in marking buttonhole locations on shoe upper material and accordingly will be discussed particularly from this viewpoint, although, as to its more general features, it has obviously a broader field of application.

Buttonhole marking machines may be divided into two classes, gang machines, and those in which a single marking tool is used to make a series of marks, the tool and the piece of work presented thereto having relative movement between the making of successive marks. Machines of the latter class, to which the present invention belongs, may be of a much simpler construction than the former and accordingly correspondingly cheaper to manufacture and to maintain in working order. Experience shows that but ton shoes are fashionable and are manufactured in large quantities comparatively infrequently, only one out of about four or five seasons. Buttonhole marking machines therefore stand idle a large part of the time. A. substantial saving in the cost of the machine then becomes important and may well be suiiicient to more than 'overbalance any advantages the gang machines may have.

It is an object of my invention to produce a simple and efficient machine for marking l'mttonhole locations on the 'buttonhole liies of shoes in succession as the work is fed forward to a marking tool.

The number and distance apart of buttonholes upon the ,buttonhole' fliesof shoes vary greatly with changes of fashion and with different styles and sizes of shoes. It is therefore an object of my invention to pro- MACHINE FOR MARKING SHOE 'UPPERS.

vide satisfactory means for adjusting the machine so that it may make any desired number of equally spaced buttonhole locating marks on the work presented to it, and 'this qulte irrespective of .what the length of the fly may actually be, and without the necessity for anycomputationof the distance be tween adjacent buttonholes. To accomplish this purpose a feature of the invention lies in the provision of means by which the machine may be operated to divide a line between the locations ofthefirst and last buttonholes into the desired number of equal parts, making an appropriate button-holelocating mark at each point of division.

In the illustrated embodiment of my in- .VGIliJiOIl there is provided a reciprocating work engaging member arranged to feed the work intermittently and a-marking member arranged to mark thelocations of buttonholes duringthe intervals in which the work is at rest. Ainovable member is provided, exemplified as a pointer movable over the work support, and arranged to control the work engaging feeding member so that the work is placed on the machine, when the marking member iselevated and the feeding member is at its extreme forward position, withthe desired location of the first mark under the punch, and with the end of the pointer over the desired location of the last mark, the operation of the machinewill divide the intervening distance into that number of equal parts predetermined, as shown, by the form of a cam surface which controls the operation of the feeding member. As the pointeris moved to correspond to the lengths of different pieces of work, the distance apart of consecutive marks is, of course,

Fig. 7 is a perspective view of the feeding and marking members, as viewed from the front of the machine; and

Fig. 8 is a diagram of a shoe upper as marked by the machine.

In the embodiment of my invention which I have selected for illustrative purposes, the machine is provided with a basev plate 10 from which rise two pairs of

standards

12 and 14. Journaled in the latter is a main drive shaft 16 driven from any suitably controlled source of power and having splined thereon, for sliding movement and rotation thereby, a conoidal cam 18. One end of this cam (the left hand as viewed in Fig. 2) is circular and is concentric with shaft 16. The other and larger end is eccentric with respect to the shaft and is substantially oval in form. Two portions of this end, on opposite sides of the shaft, are concentric with the latter and are joined by a smooth curve. The least distance from the periphery of this oval end to the center of the shaftis equal to the radius of the circle at the smaller end. Thus the cam has one portion which lies in the surface of a cylinder and another opposite portion which lies in the surface of a cone.

Bearing against cam 18 is a roll 20 journaled in the end of a lever 22suitably fulcrumed on a shaft 24 having bearings in standards 14. The other end of lever 22 is connected by a link 26, to a lever 28 fulcrumed at 30 in standards 14. Pivotally mounted on rod 32 supported by standards 12 is a member 84 provided with a removable plate 36 having a cam which is held by aspring 37 against a roll 38 journaled at the end of lever 28. The general form of this cam surface and the means by which it may conveniently be positioned and detachably connected to member 34, asby a screw 39 and a guide 'or flanges 40, are clearly shown in Figs. 4, 5 and 6. The upper end of the cam surface of plate 36 is conveniently provided with a stop 42 made in the form of a hook to limit the upward movement of roll 38 as the conoidal cam permits levers 22 and 28 to move upwardly under the influence of springs 43 which are connected to the lever 22 and to a fixed bar joining the standards 14. K

At the lower end of pivoted membersa is a pawl-like feed member 44 pivoted at 46 and held in work engaging position by a spring 48. This feeding member may conveniently be provided with a small handle 50 by which it may be moved out of work engaging position by the operative while a piece of work is being placed upon the bed of the machine.

Mounted at the end of an arm 52 is a marking tool, illustrated as a punch member 54, and a presser foot 56 conveniently made in the form of a leaf-spring. The marking tool is moved alternately into and out of work engaging position by means of a cam 58 mounted on and rotated by the main drive shaft 16 and engaging the arm 60, spring held as at 61, and rigidly connected to asuitably journaled rock shaft 62 to which arm 52 is rigidly connected.

The bed of the machine may conveniently be provided with an arcuate scale laid off in inches or other convenient units, as illustrated at the right hand end of Fig. 1. Over this scale moves the end of a pointer 64 pivoted at 66 to the bed of the machine and having rigid therewith a pulley 68 around which passes a belt 70 supported by

suitable idlers

72 and 74 and connected wit-h a cross head 7 8 slidably mounted upon rods 79 and provided with a fork engaging a grooved collar 82 on one end of the conoidal cam 18 for sliding the same on drive shaft 16 as the pointer 64 is moved from one position to another. Idler 74 may conveniently be supported by an adjustable member 84 to provide a suitable belt tightener, the member 84 being pivoted to the frame and held at the desired distance therefrom by a screw bolt as shown in Fig. 2.

In the operation of the machine, the work, for instance the buttonhole fly of a shoe, is placed on the bed of the machine at that stage in the cycle of operation thereof at which the marking member is in its elevated position and the feed member at its extreme. forward position, as illustrated in Fig. 4, with'the location at which it is desired to have the first mark directly under the marking tool 54 and with the edge of the work in approximate alinemeut with the scale on the bed of the machine. This may be facilitated by swinging the feed member upwards by means of its handle 50. Pointer 64 is now adjusted so that its end is directly over the desired location of the last buttonhole. Power is then; applied and the work fed step-by-step through the machine. Between steps the punch is lowered through the work. The feeder 44 moves rearwardly and stops, as shown in Fig. 5, the punch holding the work against displacement. The punch thereupon rises, after which the feeder moves forward, taking the work with it, and stops, as shown in Fig. 6, whereupon the punch is again lowered through the end of the :pointer.

work. This cycle of operation is repeated 'thenumber of times necessary to make the throughout its length having a curvature concentric with the drive shaft so that teeding member 44 will have a short pause at both extremes of its -movement, while the markingtool 54 is being moved into and out of work engaging position. During the rearward non-feeding movement of the feeding member 44 the work is held against undesired displacement by the marking tool 54 The ment when'the marking tool is being with drawn.

The cam surface of plate 36 is so formed thatthe feeding movements of member 44 are equal aliquot parts of the distance between the marking tool and the end of the pointer, irrespective of the position of the Thus if it is desired to mark the location of 12 buttonholes. as illustrated inFig. 8, there will'be 11 equal steps of the feeding member 44 to move the work through the distance between the first and the last mark.

To effectively operate the machine all that is necessary for the operative to know is the desired location or the first and last but tonholes togetherwith the number of buttonhole locations to be marked.

The-movement of pointer 64 to correspond to the lengths of different pieces of work slides the conoidal cam 18 on its shaft and so varies the amplitude of the oscillations of lever 28 and accordingly'of pivoted member 34and the work feeding member 44. If it is desired to make some'other number of marks it is necessary to remove cam 36 and substitutetheretor another cam of generally similar form but with its surface so shaped as to move the pivoted member 34 a greater or less distanceas the case may be when lever 28-is'osc11lated through a givenarc. It 1s necessary to provide as many of these cam bearing plates 36 asthere-are different numbersot 'buttonholes to be marked on the different pieces of work. For this reason the machine is so arranged that these cam bearing plates -36 maybe easily and quickly changed so as not to unduly delay the operation or the machine.
