PATTERN'HOLDER FOR GRADING MACHINES.

Application filed December 24, 1925.

lily invention relates to means for the proper positioning and securing of model patterns on the holding plate of a patterngrading machine. The particular embodiment of the invention here illustrated is designed and adapted to be used in the manufacuring, grading and cutting of shoe patterns. It will be understood that the illustration shows merely one embodiment of the invention adapted to 'a special use and is not intended as a limitation of the invention either as to its specific construction, or to any specific use.

Theobjects of my invention are to provide positive means for positioning and fixing model patterns on a holding plate; to eliminate the use of flags and attachments on model patterns; to provide for the machine production of finished patterns, obviating the hand finishing heretofore required; to eliminate the bolting process heretofore resorted to in pattern making; to eliminate the bolt locating and the marking and punching of bolt holes in model patterns; to eliminate the use of elevating washers on pattern grading machines; to provide improved adjustable fixing points adaptable for ready relocating on the holding plate; to provide improved meansfor therelocating of fixing points on the holding plate; to provide improved fixin'g points; to provide "an improved fixing point carri'age and' punching arm; to materially reduce manufacturing costs resulting from the saving of time and materials; and to provide the various other advantages and results made apparent from the following specification I l accomplish the objects of my invention as shown in the accompanying drawings which form a part of this specification and in which, Figure 1 shows a pattern secured to the holding plate by means of fixing point carriages positioned thereon. Figure 2 shows the fixing point carriage adaptable to slide in the grooves of the holding plate shown in Figure 1. Figure 3 is a sectional view of the fixing point carriage on the line AA in Figure 2. Figure 4 shows the hinged punching arm adaptable for mounting on the fixing point carriage shown in Figure 2. Figure -5 shows a side view of my assembled fixing point carriage and punching arm; Figure 6 is a sectional view on the line 6-'6 of Figure 1.

Referring again to Figure 1, B shows the shown in Figure 1. which fits the hinge mounting H, (shown in Serial No, 77,674.

body of the holding plate. C shows the dovetail spaces forming grooves on the plane of said plate. D shows a series of transverse grooves or lines, hereinafter called grooves, on the surface of the holding plate designed for use in conjunction with the groove M shown in Figure 4- in the proper positioning of model patterns on the holding plate for what is known as centergrade work. B

shows screw holes through which the plate is secured to the frame of the grading-inachine. B shows an orifice at the working center of the holding plate.

Referring again to Figures 2 and 3 E shows thewedge shape base of the fixing point carriage, adaptable to fit and slide as a dovetail tenon in thespaccs 0 shown in Figure 1. F shows the locking screw positioned in the threaded orifice F shown in F igure 8 a tightening of'which screw-secures the carriagewhere positioned, accomplishing this as the end of the screw F presses against the bottom of the spaces C G- shows the valley in Figure I shows the well into which fits the post J on'the hinge mounting H (shown in Figure 4-), K shows the base of the punch point L, which base fits into the receptacle K shown in Figure 3 andis interchangeable with other base carrying punch points of varyingshapes. The base 14: extends above the upper surface of the carriage base E so as to hold the pattern,

positionedonthe piu'ichv point-L, away from :thexsurfaceof the holding plate, thus-elimimating the use of loose washers to effect this purpose. K shows an opening available for ready conveniencein the application of pressure from the underside when rennoving the base K for interchangeable or replacement purposes.

Referring again to Figure t, J shows the post on the hinge mounting H, which post fits into the well Ish'own in FiguresQ and?). 3 ld shows the punching"arm,-hingedby the pin N in the orifice H' on the mounting H. '0 shows the base of the female unitil into which unit fits the punch point L, shown here in halfcircle form, but optionally 'varied to circular, square; oblong, diamond,

cross, triangle or other shape to fit the style of punch point-used. V shows an opening available for ready convenlen'ce 1n the-ap plication ofpressure from the underslde in removing the unit 0 for interchangeable or replacement purposes. M shows a groove on the punching arm M, preferably positioned so as to register over the center of the groove C thereunder, designed for use on centergrade work in. conjunction with the transversal grooves D in the proper positioning of model patterns on the holding plate.

Referring again to Figure 5, M shows the position of the punching arm when swung back from the punch point L, as shown in Figure 1.

Referring again to Figure 1, B shows the holding plate with a pattern Q secured in position thereon by my improved means and showing the various arms M respectively in .the punching position with the female unit P over the punch point L, in a midway raised position, and in the extreme open position lying substantially parallel to the holding plate. After the punching process, comprising a closing of the female unit 0 over the point L, by which closing the pattern is forced and held onto the points L, the arms M may be raised as shown in Figure 1, or optionally removed from the holding plate by detaching the post J from the well'I in the base E.

In centergrade work, for improved results and major time savings, in preparing to advantageously and accurately locate the model pattern on the holding plate, a complete experimental pattern is first positioned on the plate with the throat of the vamp at the center B Line markings are then made on the various parts of the experimental pattern following the transversal grooves D on the holding plate, and additional line markings at the groove M These markings on the various parts of the entire experimental pattern disclose the exact positions on the holding plate of what later comprise the various disjointed parts of the experimental pattern. These positions are significantly important after the experimental pattern is divided for example into what is known to the'trade as the foxing, the quarter, the saddle and vamp, or such other parts as may be designed. The identical markings on the experimental pattern are then transferred to the model patterns and the correct positioning thereof on the holding plate is assured by matching up' said markings with the transverse grooves D and the groove M herein before referred to.

It is possible to eliminate the punching arm M and female unit P, using in place thereof a mallet or hammer of, wood or other soft material, a blow from which on the porcient and satisfactory. It is also possible to eliminate the grooves C in the holding plate, substituting therefor a series of orifices into which may be inserted holding posts projecting from the underside of the fixing point carriage. I assume all such and other variations and equivalents as may be construed to fallwithin the scope of the appended claims.

Having thus described my invention '1 claim as new and desire to secure by Letters Patent of the United States of America:

1. In a device of the kind described, a holding plate, a plurality of movable members, means for adjustably fixing said members to the holding plate for placement at certain points thereon, a fixing point carried by each movable member and adapted to pierce and hold a pattern placed thereon, said points being bodily removable from said movable members. a
