GEORGE F. DUNN, OF BROCKTON, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TO WILLIAM B. ARNOLD, OF NORTH ABINGTON, MASSACHUSETTS.

VAIVIP THROATING AND MARKING MACHINE.

Application filed October 21, 1909.

To all whom it may concern Be it known that I, Gnonon F. DUNN, a citizen of the United States, and a resident of Brockton, in the county of Plymouth and Commonwealth of Massachusetts, have invented an Improvement in Vamp Throating and Marking Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to dieing and marking machines and more particularly to machines for throating and marking the vamps of boots and shoes, and among other objects provides means for accurately positioning Vamps beneath a throating die, and adjustable means for marking the vamps.

The character of the invention may be best understood by reference to the following description of an illustrative embodiment thereof shown in the accompanying drawings wherein:

Figure 1 is an end elevation of a vamp throating and marking machine embodying my invention; Fig. 2 is a side elevation of Fig. 1; Fig. 3 is a vertical section, taken on line 33 of Fig. 1; 1 is a plan of Fig. 1 with the cutter die and its support removed; Fig. is a horizontal section, taken on line 55 of Fig. 1; Fig. 6 is a horizontal section taken on line 6-6 of Fig. 2; and Fig. 7 is a section taken on line 77 of Fig. 5.

The illustrative vamp throating and marking machine shown herein as embodying my invention comprises (Fig. 1) a die block 7, supported on the usual table 9, rotative about the central post 10 (Fig. 4) projecting upwardly from the machine base 11. The upper periphery of said table 9 is provided with a rack 12 adapted to cooperate with the usual devices, (not shown) for intermittently turning the table to distribute the wear on the surface of said block.

To cut the work on the die block a U- shaped throating cutter die 13 (Figs. 2, 3, 5 and 6) is provided of flexible ribbon metal sharpened on its lower edge and is carried by frame 15, secured to a vertical post 16, which may be vertically reciprocated in any suitable manner to cause the cutter Specification of Letters Patent.

Patented Nov. 17, 1914:.

Serial No. 523,902.

to descend at the proper times toward the die block to cut the work thereon. To adust the die to cut throats of various sizes the legs of the die may be mounted in carriers 17 and 18 (Figs. 3 and 6), having respectively upwardly projecting

studs

19 and 20, extending through diverging elongated slots 21 (Fig. 5) in a horizontal plate 22 secured to and depending from the frame 15. These studs also extend through elongated slots 23 in a sliding plate 24, superposed on the plate 22, the latter slots being substantially perpendicular to the median line of the cutter die, and cross the diverging slots 21 referred to. It will be apparent that by sliding the plate 24: on the plate 22 the

studs

19 and 20 and the cutter leg carriers 1? and 18 will be caused to approach or recede from each other according to the direction in which the sliding plate 24 is moved. The curved end or bend 13 of the U-shaped cutter may be positively adjusted to conform to the adjustment of the supports for the legs of the cutter by a narrow, sliding end carrier 25 (Figs. 3 and 6), guided between triangular shaped guides 25 (Fig. 6) secured to the under face of said plate 22, the diverging edges 25 of said guides also constituting guides for the incurved ends of the cutter leg carriers 17 and 18. The carrier 25 has a depending projection 25 curved to conform to the curvature of the cutter, said cutter being received between said projection and the curved, depending end of a strip 26 screwed or otherwise secured to said sliding carrier 25. To move this carrier with the plate 21 referred to, a stud 27 is secured to said carrier and projects up through an elongated slot 28 (Fig. 3) in the plate 22 and is secured at its upper end to said plate 24. The plate 24. may be slid on the plate 22'by means of a screw 36. having an end threaded into a lug 37 extending vupwardly from the plate 2 1. The opposite end of said screw is journaled in a bearing in an upturned end 38 of the plate 22 (Fig. 2), and is provided with a suitable handwhcel 39. The screw 36 is capable of rotation in its bearing but is prevented from longitudinal movement therein by suitable collars. As a result,

when the handwheel 39 is rotated the lug 37, with its plate 24, will be slid causing the cutter to expand or contract as desired. It will be apparent that as the leg supports approach, the, curved portion of the cutter will be shorter and the straight portion or legs of the cutter will be proportionately longer.

To permit said legs to slide in their supports to conform to the narrowing or widening of the curve or bend of the cutter they are not fixed to said supports but are adjustably supported in their carriers by pins 29 (Figs. 3 and 6) projecting through the legs of said cutter and received by elongated slots 29 in said carriers 17 and 18.

To prevent the vam as or the throat blanks cut from said Vamps from being pulled up from the die block with the cutter after the cut is made, a stripper may be provided for said cutter. Herein a stripper plate 30 (Figs. 3 and 6) smaller than but of a shape similar to said cutter is supported within the latter by guiding studs 31 received by hollowposts 32 depending from the plate The stripper plate 30 is supported by a central plunger 33 entered into a hole 33 in the plate said hole being counterbored to receive a head 3% on said plunger. This head is normally seatedat the base of said counterbore by a spring 35 encircling said plunger and compressed between the under face of the plate 22 and the stripper plate. hen the cutter descends to cut the throats in the vamps the stripper shares in this descent until it comes in contact with the top vamp when its movement is arrested by its engagement therewith. As the cutter continues downwardly to cut through the vamps the base of the counterbore withdraws from under the stud head 3% and the spring 35 is compressed. WVhen the cutter ascends the stripper will press the Vamps down until after the cutter is'abovesaid Vamps. The continued upward movement of the cutter will cause the plunger head 34 again to be seated on the base of said counterbore and the stripper will be drawn up from engagement with the Vamps.

The downward movement of the frame 15 is utilized not only to cut the throats in the Vamps but also to mark the latter for any desired purpose, as to indicate the position of the shoe tip on the vamp. To this end vertical marking pins l0 are provided (Figs. 1, 2, 3 and 5) and may receive adjustment corresponding or conforming to the adjustment of the cutter die, by passing said pins through diverging elongated slots e1 (Figs. 5 and 6) in the plate 22 referred to and upwardly through guide wings 42, each provided with elongated slots 43 we tending substantially perpendicular to the cutter die median line, and crossing the diverging slots 41. These pins may occupy stripper sleeves 45 the upper ends of which ed and slid in said cross slots as described these heads 51 are yieldingly pressed by said springs into sliding engagement with horizontal bridge bars 55 (Figs. 1, 2 and 5), which diverge similarly to the slots l1 and are supported at their ends above the plate 22 by spacing sleeves 57, secured to said plate by suitable bolts 59. When the cutter die descends to cut the vamps the stripper sleeves 45 share this movement until they come into contact with the top Vamps, when they are arrested by their engagement therewith, the continued downward movement of the cutter die causing the marking pins 40 to descend against the resistance of the springs 53 and project through the stripper sleeves andpenetrate or mark the Vamps. When the cutter die is moved upwardly away from the Vamps the stripper sleeves will remain in contact with the surface of the top vamp and cause the Vamps to be stripped from the marking pins 40. By the time the marking pins have passed above the lower ends of the stripper sleeves the stripper sleeve collars d7 will be engaged by the wings 42 and will continue upwardly with the die.

The marking pins d0 hitherto have been adjusted simultaneously and in conformity with the cutter die adjustment as by connecting the marker guides directly to a nut 1 on the screw 36 thereby causing the markers to share directly the adjustment of the die. By my invention the marker guides may not only be adjusted in conformity with the cutter die to correspond tothe size of vamp throat cut, but a gage is provided for said markers whereby they may be given a preliminary adjustment relatively to said die, so that, among other things, when marking the positions of shoe tips the distance from the vamp throat or die to the inner edge of the tip may be varied as desired. This gage comprises the marker guide wings 4:2 referred to which are secured to or form parts of vertical guide plates 61 (Figs. 1 and 5), said plates being provided with dovetailed projections 63, which are received by similarly shaped horizontal grooves, in a nut 65, threaded on the cutter die adjusting screw 36 at a point between the lug 31 and the bearing end 38. These opposed guide plates are connected by a bridge plate 67, the latter having a threaded opening receiving an adjusting screw 69 provided with a handwheel 70, said screw being journaled in an open bearing 71 in a lug 73 projecting upwardly from the nut 65. The screw is capable of rotation in said bearing but not of longitudinal movement relative thereto. When the die adjusting handwneel 39 is rota ed to vary the adjustment of the cutter die the nut will travel on the screw 36 causing the marker guide wings $9. to share in this movement and be adjusted in conformity with the adjustment of the throating die for the size desired. By turning the handwheel of the preliminary adjustment screw 69. the marking pin adjusting wings 4:2 may be slid relatively to and independently of the nut 65 to vary the distance of the marking pins from the curved end of the cutter die, furnishing several adjustments for each adjustment of said die. This is found to be a very advantageous construc tion, since the length of the vamp between the throat and shoe tip may be varied irrespective ot' the throat cutter adjustment. The independent marker adjustment is equally advantageous in marking points for bluchers and other purposes as desired.

To accurately the marking pins in predetermined preliminary positions of ad justment the referred to (Fig. 5) includes indicating means comprising a graduated scale 77 on a plate '77 which is mounted in a groove in the top of one of the marker guide plates 61, said scale being adapted to be read against an index pointer 78 (Fig. 5) secured to one side of the adjusting screw lug 73. Said scale is herein divided into three divisions, indicating marker adjustments for shoe widths 1 to 6, each line indicating two widths.

To accurately and simultaneously set the cutter die and markers into predetermined positions of adjustment, indicating means are provided including a graduated scale 79 on a plate 79 1 and mounted in a groove in the top of the plate 22, said scale plate being herein divided transversely into widths from 1 to G, and longitudinally into sizes numbering from 5 to 11, inclusive, for each of said widths. Said scale may be read against an index edge 81 of one of the marking pin adjusting wings e2 which slides over said plate 79. In using the indicating means shown herein the marker pins may be given a preliminary adjustment relatively to the throating die by turning the small hand-screw 70. As illustrated herein the scale line 5 G is set in line with the index pointer 78. After this preliminary adjustment is made the large handwlieel 39 is turned to cause the cutter legs to approach or recede to give the desired cutter ad ustment and to give the final adjustment of the markers, bringing the wing reading index 81 in line with any of the sizes in either of the rows of size v figures indicated by

widths

5 and 6 on the margin of said scale plate 79. As illustrated herein the edge 81 is set in line with size S of width 5. If the preliminary adjustment is on line 3et, the final adjustment may be on any of the sizes in either of the rows of size figures indicated by widths 3 and 4- on the margin of said scale plate 79. And if the preliminary adjustment is on line 1 2, the final adjustment may be on any of the sizes in either of the rows of size figures indicated by

widths

1 and 2 on the margin of the scale plate 79. As a result the markers may be adjusted independently of said die. As shown herein the distance between the die and the markers in-- creases as the widths are changed from 56 to 1-2.

The styles of shoe caps or tips change from time to time and to provide indicating means of sufficient range to indicate any length of cap or any extent of vamp between the curved end of the vamp throat and the edge of the shoe cap the capacity of the scale 77 on the plate 77 may be increased by sliding said scale plate in its groove. To accurately indicate the adjusted positions of the plate 77 the latter is provided with what may be termed a style scale 77 which may be read against an index line 77 on an edge portion of the top of one of the guides 61. Herein this scale is divided into divisions numbered from 1 to 4, but any number may be used as desired. The plate may be secured in its adjusted positions by a set screw 77 entered through a slot 7 7.

In similar manner the range of the scale '79 may be increased by sliding the scale plate 7 9 in its groove and its positions of adjustment may be indicated by a style scale 79 (Fig. 5) divided into divisions, herein also numbered from 1 to l, said divisions being adapted to be read against an index line 79 on said plate 79. This plate may be secured in its adjusted positions by a set screw 79 entered through a slot 7 9 in said plate.

It will be apparent that when said plates and 79 are in the positions shown inFig. 5 a number of indicated adjustments may be effected as previously described, but by sliding said plates and with reference to the style scales 77 b and 79 a new set of adj ustments may be had by the scales 77 and 79' with each of the divisions of the style scales 77 and 79 as a nucleus.

In using the machine a great many Vamps may be cut oil. one size, and the machine may not need to be adjusted with much frequencv, but when it is desired to cut vamps of different sizes and with dilferent markings, the adjustments may be very easily and quickly made, by simply turning the handwheels with reference to the indicating means, as described.

An important feature of my invention consists in providing means whereby vamps may be accurately positioned on the die block beneath the cutter. To this end the supporting area of the block is supplemented by a horizontal plate 83 (Figs. 1, 2, 3 and 4) detachably connected to the base 11 by vertical studs 85 projecting downwardly from the plate 83 and having reduced ends 87 adapted to be received by hollow posts 89 projecting upwardly from the base 11., The inner portion of this plate adjoins the die block 7 on a level therewith, and is shaped to conform to the peripheral contour thereof. The side edges of the plate 83 are provided with guides 91 (Figs. i and 7) which extend beyond the plate 83 and overlie the-die block 7 "for a substantial distance. Mounted to slide on said block is a vamp supporting tray 93, (Figs. 1, 4 and 7) of sheet material and having side strips 94: secured thereon and adapted to slide in said guides 91. The tray has a U-shaped cut away portion sufiiciently large to permit the thro-ating die to pass through said tray for any adjustment of said die. The inner end of this tray is provided. with a transverse cleat or stop 97 (Figs. 3 and 4) herein of angle iron secured thereto. One or more vamps may be accurately positioned on said tray 93 by long, curved guide fingers 99, 101, resting on the tray 93 and adapted to slide toward and from each other to center and accurately position the vamps on the tray with their ends abutting against the stop 97. The guide fingers 99 and 101 may be adjusted toward and from each other by an oppositely threaded screw 103, rotative in, but incapable of longitudinal movement in a bearing box 105, secured to the side of an upwardly extended end 107 secured to said tray. To contribute to the guidance of the fingers '99, 10 1, their screw receiving ends 109 are enlarged and squared, to slide against the face of said end 107 and the adjacent surface of the tray 93. The screw 103 may be turned to move said fingers toward or from each other by a suitable handwheel 111. Since the opposite outer edges of a vamp are not symmetrical, the guide finger 99 is provided with a. curvaturesomewhat greater than that of the finger 101. Vamps for right and left shoes may be cut in a single operation my superposing some of the vamps with their smooth sides up and others with their rough sides up. To permit the marking pins to pass through the tray in any of their positions of adj ustment, said tray is provided with oblique, elongated slots 113.

To accurately position the vamp-receiving tray beneath the cutter die and into positions corresponding to the cutter die and marker adjustments, a stop 115 (Figs. 1,

to receive an adjusting screw 125.

2, 3 and is mounted on the sliding, ad.- justing plate 2 1 for the cutter. Herein this stop is in the form of a narrow strip secured onto said plate adjacent the screw lug 37. This strip extends horizontally from said plate over and beyond the plate 22 and thence is bent vertically downwardly to bring an edge 117 of its depending end adjacent one of the tray guides 91 as well shown in Figs. 2 and 5. Cooperating with this stop is a tray positioning gage (Figs. 1, 2, 4L, -5 and 7-) secured to one of said side strips 9 1 (Fig. 7). This gage comprises a block 121 hollowed out horizontally to receive a longitudinally sliding sleeve 123 which may be interiorly threaded The shank of this screw is rotative in a'bracket 127 (Fig. 2) secured to an end of said block and is prevented from longitudinal movement therein by collars 129. The gage is provided with indicating means comprising a scale 131, herein on the top of the block 121 (Figsa and 5). Said scale may be divided into divisions numbered to indicate adjustments for vamp sizes from 5 to 11. To indicate the positions of adjust ment of said sleeve the block 121 is slotted to receive a T-shaped index 133 secured to said sleeve and movable therewith. The scale may be read against the edge 135 of said index.

In use, the tray is slid from beneath the cutter die out onto the supporting plate 83. One or more vamps 136 (Fig. 3) are then placed onthe tray with their ends abutting against the stop 97. The handwheel 111 is then turned to cause the fingers 99 and 101 to approach and accurately center and maintain the vamps in their superposed positions. The cutter die and markers having been adjusted as described to cut, for example, the proper throat in a vamp, size 8 width 5 (as shown) the tray gage screw is turned to bring the index edge 135 in alinement with the line indicating size 8 on the scale 131. The tray is then slid in under the cutter die 13 until the outer end of the index sleeve 123 abuts against the edge 117 of the depending stop 115 whereupon the vamps are accurately positioned to receive the proper length of threat to conform to the size of the cutter adjustment. After the die has descended and cut the throats of the vamps the tray 93 may be slid out from beneath the die until the curved portion of its U-shaped opening 95 projects beyond the outer edge of the tray support 83. A slight downward pressure on the throat blanks, remaining in the throat after the cutter is withdrawn, will cause the ends of said blanks to project down through the opening 95, permitting them to be readily pulled therethrough.

It will be understood that my invention is not limited to the particular embodiment shown herein, but that various modifications may be made without departing from the spirit and scope of my invention.
