PRECISION GARMENT PATTERN GRADING TOOL -Filed sept. s. 1954 2 sheets-sheet 1 AGENT July 15, 1958 y 1. sTURMAN PRECISION GARMEINT PATTERN GRADING TOOL Filed sept. s. 1954 2 Sheets-Sheet 2 United States PRECSIN GARMENT PATTERN GRADNG TL Isidore Stormarn, Yonkers, N. Y. Applicationgeptember 3, 1954, Serial N 454,13! s claims. (ci. 33h11) tioning is conveniently accomplished by providing a holder for the pattern which is mounted on a support for movement in two dimensions.

It is anobject of this inventionto provide an improved device of the above character having means for accurately indexing the pattern holder in several positions, relative to its support, into which it may be selectively moved by rectilinear displacement in two orthogonal directions.

Another object of this invention is to provide, in a device of this type, an improved clamp for `attaching either a one-piece pattern or a plurality of complementary pattern pieces to the holder.

The abo-ve and other objects and features of my invention will become more fully apparent from the following description of a preferred embodiment, reference being had to the accompanying drawing in which:

Fig: l is a top plan View of a pattern grader according to the invention;

Fig. 2 is a side elevational view of the device shown in Fig. l;

Fig. 3 is a side elevational View, on a larger scale, of the movable holder forming part of the device of Figs. l and 2;

Fig. 4 is a top plan view similar to Fig. 1 but drawn to a smaller scale and also showing an extension of the holder clamp adapted to engage a plurality of pattern pieces;

Fig. 5 shows part of the clamp extension of Fis. 4 on a larger scale;

Fig. 7 is a cross-sectional view taken on the line Vli`Vll of Fig. 5; and

Fig. 8 is an enlarged, fragmentary cross-sectional view taken on the line VIII-VIH of Fig. 4.

Referring lirst to Figs. 1 3, there is shown a device generally designated 1t) whose main parts are the following: A plate-like support 1i, formed with a channelshaped extremity 1 2 having screws 13 for attaching it to the edge of .a table or the like (not shown); a car- 6d ringe i4, sfida-ble on support 1l and comprising a guide i5 which is guided for rectilinear movement, paraliel lo channeled edge 12, by means of grooved blocks 16, 17 rigid with support L; and a holder 1S, of essentially platedike configuration, slidably guided lfor movement traverse to edge 1?. by means of grooved blocks 1??, 2t? rigid with carriage la.

An indexing strip 2l on guide block i7 is provided with indentations 22 adapted to receive the tip of a latch member 23 which is slidably guided in a housing mounted on guide plate iii. A handle 2S, projecting upward-ly from latch 23 through a slot ltd in hnusinsy M 'a' 2,842,847 ce Patented July 15, 1958 "i shown on the drawing) or in millimeters, to determine the extent of displacement of the holder 18 from a normal or'zero position. In Fig. l there has been illustrated, in dot-dash lines, the relative displacement between holder 1S and carriage 14 as well` as that between carriage 14 and support 11; the latter displacement, for the sake of clarity, has been illustrated by showing support 11 in an alternative position, although it will be understood that generally the support will be stationary and carriage 14 along with holder 18 will be moved with respect thereto.

Suitable anti-friction means, e. g. balls or rollers, may be inserted between the relatively movable elements 11, 14 and/or 14, 1S if desired.

The illustrated relative displacement of carriage 14 and support 11 from zero position exposes a slot 32 (dotdash lines, Fig. l) in the base of carriage 14 through which pass several pins 33 serving to secure the guide block 17 to support 11.

As best seen in Fig. 2, the forward po-rtion 34- of holder 13 curves `downwardly so that its underside is flush with that of support 11, whereby the weight of the pattern engaging clamp carried on this forward portion is directly supported by the surface of the table to which the device is attached. This clamp comprises a lever 35, pivotally mounted between a pair of lugs 36 rising from holder 13, anda pressure bar 37 pivotally attached to the front end of lever by means of lugs 38. Bar 37 is provided with rubber pads 39 adapted to press a piece of cardboard or the like, bearing the desired pattern, against a first or lower clamp jaw represented by holder portion 34, the clamping force being supplied by a compression spring 40 inserted between the rear end of lever 35 and holder 18.

The pivotal mobility of lbar 37, representing a second or upper clamp jaw, around the front end of lever 3S can be utilized for the purpose of attaching to the holder 18 an extension generally vdesignated 41 and shown in Figs. 4 8. This extension comprises a supporting rail 42, of considerably greater length than bar 37, which is attachable to this bar by screws 43 when the bar is swung out of its normal position as illustrated in dot-dash lines in Fig. 5. Slidably mounted on rail 42 are a plurality of arms 44, each with a head 45 which embraces the rail 42 and can be tightened `thereon by means of a screw 46. Each arm 44 serves, in turn, as a support for a plurality of L-shaped fingers 47 having spring clips 48 attached to them by rivets 49; lingers 47 are likewise provided with heads 50 which slidably embrace the associate-d arms 44 and can be immobilized with respect thereto by screws 51.

It will be apparent that each of the fingers 47 with its attached spring clip 48 may grip an individual piece of cardboard forming part of an overall garment pattern, or that several of these linger-clip assemblies together may engage such a pattern piece. Thus, single-piece patterns may be engaged by the clamps 34, 37 whereas multi-piece patterns can be conveniently mounted on the extension 41, using as many clip members thereof as required. The desired parallel displacement in two dimensions will in either case be effected by the withdrawal of latches 23, 29 from indentations 22, 28 and subsequent re-engagement therewith in accordance with the markings provided thereat.

My invention is, of course, not limited to the specific construction described and illustrated but may be embodied in a variety of modifications without departing from the spirit and scope of the appended claims.
