14 Claims.

This invention relates to the grading of patterns for garments and particularly to a method whereby all of the patterns of one style inany of the usual range of sizes may be graded simultaneously on a quantity production scale.

In the field particularly of manufacturing womens wear such as dresses in large quantities, popular garments of any one style are customarily made in all the size ranges such as juniors which are sizes 9 to 19, misses sizes 12 to 20 and womens sizes 36 to 46, thereby necessitating the production of a considerable number of patterns for each style. In shops producing many styles of garments, the patterns needed for the various styles and sizes for each style run into a relatively large number. In the misses range of five sizes 12, 14, 16, 18 and 20 a basic pattern for a selected size as size 14 is first made, after which the patterns for the remaining sizes are graded v individually from the basic pattern, one size at a time and this at present is and necessarily has been the customary procedure involving considerable time, efiort and expense besides being subject to cumulative errors. Insofar as I am aware, no attempt has ever been made to grade patterns commercially on a wholesale or mass production scale in the garment field, as it has been considered impossible to do so because of shifting the blanks relatively to each other preparatory to making cuts for the respective pattern edges successively and between shifts through the entire pile or stack of blanks.

The invention further contemplates the provision of an economical method of grading patterns, eliminating certain of the operations required by present methods and combining other operations whereby a stack of pattern blanks at a time are manipulated, clamped and cut to produce a complete set of graded patterns at one I time instead of one at a time.

The various objects of the invention will be clear from the description which follows and from the drawings, in which Fig. 1 is a top plan view of a typical basic pattern put in folded position on the top of a, stack of folded paper pattern blanks preparatory to grading the entire stack as a unit, each of the blanks being large enough to have the largest pattern desired cut therefrom, the thickness of the paper being exaggerated for clarity.

Fig. 2 is a similar view of the stack after the folded blanks have been shifted transversely and the stack clamped together, showing the first or bottom out being made by a suitable saw through the entire stack.

Fig. 3 is a similar view of the stack with the blanks shifted again to align those edges of the inohoate patterns which are to become the left edges, showing the stack stapled together and the second cut at said left edges being made through the stack by a pair of shears.

Fig. 4 is a similar view of the next shifted and stapled position of the stack with the edges which are to become the edges of the patterns at the arm holes coinciding and the out made there through the entire'stack with a knife.

Fig. 5 is a similar View of the stack showing the partly finished patterns shifted again into position to'align the edges of the patterns at the neck opening and showing said edges cut and coinciding.

Fig. 6 is a similar view of the stack showing the shoulder lines of all the patterns coinciding and cut.

Fig. 7 is a side elevational view of the folded stack of blanks shown in Fig. 1 and showing enough blanks to make several of each size.

Fig. 8 is a similar view of the finished stack constituting the complete graded patterns before they have been unclamped and separated from each other.

The invention has been illustrated and will be described in connection with misses sizes of womens wear such as dresses. It will be understood however, that the invention may be applied also to childrens and mens wear of certain types requiring the grading of patterns and in any range of sizes, that any number of patterns of anyseleoted sizes may be graded in the same stack and that the invention is not limited to making all of the patterns of different sizes as any selected number of each size may be made during the grading operation. As shown in Fig. 8, a duplicate of the basic size 14 pattern has been made at the same time that two of size 12, three of size 16, three of size 18 and two of size 20 are graded by my method, making eleven patterns in the stack 10 of five diiferent sizes. The

patterns are made of the usual strong, relatively stiff paper or other suitable material but without the necessity for marking outlines, the re-- spective edges of the basic pattern II serving as cutting guides. The blanks designated l2 are for size 12 patterns, blanks I4 are for size 14, blanks I6 are for size 16, blanks I8 for size 18 and blanks 20 for size 20.

Said basic pattern I I is usually of size 14 in the range of sizes hereinillustrated and if symmetrical as shown, is folded in the usual manner as at I3 along the middle line thereof. The paper blanks I2, I 3, I6, I8 and 20 are first folded and stacked, each blank being large enough for the largest size to be graded, in this case size 20 as seen in Fig. 1 for ease in cutting and stacking and blocking out the blanks from. a multiply roll, stack or the like. The folds I! of the blanks and the fold I3 of the pattern I I are made coincident and the blanks of the stack are then temporarily fastened together in any convenient manner in I the thus stacked positions thereof.

'their operative ends, urged together by a coil spring around the pivot, one end of the spring bearing against one part and the other end designed to be opened up widely enough to receive the stack and to exert enough spring pressure thereon to prevent any relative movement of the pattern blanks after they have been shifted into the required positions for cutting with corresponding edges in predetermined stepped relation. However, the blanks may, if desired, be quickly stapled together in the positions shown for example in Figs. 3-6, the staples 35 being of the thin wire type which are easily opened up and withdrawn to free the blanks from each other. It being the purpose of the present invention to eliminate difficult and time consuming operations, it will be understood that any suitable quickly detachable and quickly acting attaching tools may be employed for holding the pattern blanks in place in the stack after they have been shifted and prior to thecutting operation thereon.

. the spacing of the blanks horizontally or vertically. The cuts mentioned eliminate the need for measuring or otherwise marking the blanks or i the amount of overlap or overhang thereof on the adjacent blank. They indicate the amount of relative vertical shifting of the consecutive or alternate patterns, which amount is the same between consecutive sizes. However, a special cut 40 for the size 12 patterns is made above the cut 36. The distance between the cuts 4!! and 36 is twice that between the other consecutive cuts because the pattern blank I2 is placed on a preceding blank I6 in the stack and sizes 12 and 16 are not consecutive but are alternate sizes, one being two sizes different from the other. Size 14 4 being the master pattern, it isplaced on the top of the stack and not between blanks I2 and [S where it would normally be expected. Hence blank I2 is shifted twice the normal distance between consecutive blanks relatively to the blank l6 and the special cut 40 is made accordingly, but is utilized only for pattern l2 in the present illustration.

Similarly, cut 31 is made through the pattern I I and all the blanks in the stack simultaneously and at the required distance from the folds of the blanks to indicate the smaller amount of the shifting movement horizontally of consecutive blanks (Figs. 2 and 4). The second cut 38'is made preferably the same distance from. the cut 31 as the latter is from the fold I 3 or I 'l to indicate the double spacing as required for Fig. 3. The

. special cut 39 is to indicate the spacing between the blanks I2 and I6 in Fig. 3 as double that of the consecutive blanks or patterns for the reason already explained "in connection with the special cut 4!]. Since the cuts 31, 38, 39 are made preferably near the lower parts of blanks in the stack, it is advisable to make a duplicate set of cuts 31a, 38a and 3911 respectively .aligned with the cuts 31, 38 and 39 and similarly spaced from each other and from the folds, said cuts being made near the upper part and through all of the blanks of the stack simultaneously so that the folds are maintained parallel when -the blanks are shifted, each fold being aligned with two corresponding cuts in a manner soon to be explained.

After all of the indicating cuts have been made in the stack, the next step is to arrange the blanks in their new shifted positions which depend on the first edge to be out. As shown, the blanks are shifted into generally stepped relation preparatory to cutting the corresponding bottom edges of all the blanks simultaneously, cutting the holes I9 through the stack and also making in the cut bottom edges the notches as 25, 28 common to all of the blanks to indicate for example the position and width of a dart in each blank tapering to the hole I9.

As shown in Fig. 2, the blanks I2 have been shifted horizontally to arrange the folds thereof to the left of the fold I3 of the basic pattern II, while the preceding blanks I6, I 8 and 20 have been shifted to the right of the fold I3 toarrange the respective folds thereof in stepped relation the required distance from the fold of the preceding blank whereafter the blanks are clamped or stapled together. The required distance between the folds of successive blanks need not be measured and is the distance between the fold of the blank being set and the cut 3'! of the preceding larger sized blank in the stack. In detail, the blank I 8 is shifted so that its folded edge is aligned with the cuts 31 and 31a of the blank 20. The blank I6 is then aligned with its fold at the cuts 31 and 31a of the blank IS; the blank I2 has its fold at the cuts 38 and 38a of the blank l6 and the pattern I i has its fold at the cuts 31 and 31a of the blank I 6, it being now understood that the blank I6 is used to align both the next blank I2 and the top pattern I I.

Obviously, all of the size 12 blanks are shifted the same amount as the other size 12 blanks with the folds coincident. The same is true of the size 14 and 16 blanks and 0f the others in the stack. The outlines of the blanks for the same size being the same, the multiplicity of shifted patterns and blanks of the same sizes are not separately shown and cannot be indicated in Fig. 2 but are shown in Fig. 8. The entire -38 and 38a of the preceding blank 20.

- I6 is shifted to the left until its fold coincides terns.

the cuts 38, 38a of the blank I6 and its bottom clamped or stapled stack, consisting in the case illustrated of eleven folded blanks or twenty-two thicknesses of paper, exclusive of the basic pattern, is now out along the common or coincident bottom edge 2| thereof by means of any suitable ing the individual incomplete patterns from each other.

Preferably, the side or second set of edges of the patterns are then cut by again shifting the freed blanks into the relative positions thereof shown in Fig. 3, whereinthe stepped relation or spacing between the folds of consecutive blanks is doubled from the position of Fig. 2 to carry into coincidence the theoretical lines destined to become, and which in the blanks are, the in choate side edges of the patterns. That is,

' the blank I8 is shifted to the left on the blank until its folded edge coincides with the cuts Blank with the cuts 38and 38a of the blank I8. Blank I2 is shifted to bring its fold into coincidence with the cuts 39 and 39a of the preceding blank IB. Finally the pattern II is shifted to bring its fold to the cuts 38 and 38a of the blank I6. The

blanks so arranged are again clamped or stapled and the cut 21 made through the entire stack without any necessity for tracing the outline of the cut to be made but merely by following the selected edge of the basic pattern as a guide. In Fig. 3, the shears 28 are illustrated as P81101111.-

ing the cutting operation, it being understood that any of the cuts may be made by any suitable means.

The stack is then again unfastened and the individual incomplete patterns again shifted to the relative positions of Fig. 4 wherein the folds and side edges are symmetrically spaced in stepped relation, the respective folds coinciding with the cuts 31, 31a of the preceding blank and the bottom edges being similarly spaced at the respective cuts 32 of the respective preceding blanks to bring into coincidence what ultimately will be the edges of the arm holes of the completed pat- The fold of the blank I2 however, is at edge 2| is at the cut 33 of the blank I6 for the reasons hereinbefore explained. The pattern II is in normal shifted position relatively to the blank I6, its fold being at the cuts 31, 31a of the blank I6 and its bottom edge at the cut 32 of blank I6. After shifting, the patterns are reclamped or again fastened in a stack and the arm hole cut 28 made through the entire stack by any suitable tool, the knife 29 being shown for illustrative purposes in Fig. 4.

The unclamping, hifting and re-clamping and cutting of the stack are repeated in the same manner to cut the coincident neck lines as shown in Fig. 5, the horizontal shifts being to make the folds of all the blanks coincident and the vertical shifts tobring the edge 2| of each blank except blank I2 into coincidence with the cut 33 of the preceding blank. The edge 2| of blank I2 is at the cut 36 of blank I6. The bottom edge 2| of pattern II is at the cut 33 of blank I6. Finally, to cut the final coincident shoulder lines 3| as shown in Fig. 6, the folds of all the blanks remain coincident, while the vertical shift is increased over that of Fig. 5 by one additional space, bringing the bottom edges 2| into coincidence with the cut 34 of the preceding blank. The edge 2| of the blank I2 is at the cut 40 of the blank I6 and the bottom edge 2| of the basic pattern I is at the cut 34 of the blank I6. The final positions of the completed patterns in the stack are shown in Figs. 6 and 8. After completion, the patterns are unfastened and freed of each other and separated ready for use.

It will be noted that the method herein disclosed is peculiarly adapted for performance by mechanical means such as machine tools of the proper kind, that stack indication and cutting of differently sized patterns in the same stack replaces individual cutting, that measuring and marking of individual patterns and the cumulative errors frequently inherent in such marking and measuring are eliminated, that inspection of the clamped stack shows at a glance whether the patterns have been shifted the proper distance, that the time required for pattern grading and the expense involved therefor may be greatly reduced over present relatively slow and cumbersome methods, that the method is applicable to all the patterns in womens outer garments and to many type of other garments and that I have provided a method well designedfor commercial mass production of graded patterns.

Various obvious changes may be made in the method herein shown and described without departing from the spirit of the invention defined in the appended claims and I therefore intend the above disclosure to be illustrative rather than limitative of the invention.
