INGRAM PATTERN GRADING DEVICE 3 Sheets-Sheet 3 Filed April 2, 1954 INVENTOR DZXQ/V JVGRM United States Patent r' 2,711,588 1C6 Patented June 28, 1955 PATTERN GRADING DEVICE Dixon Ingram, Brooklyn, N. Y. Application April 2, 1954, Serial No. 420,715 7 Claims. (Cl. 33-12 unskilled and'skilled alike, particularly in tailoring and garment and dress making, to hold a pattern of one size and move it over an underlying piece of material the correct requisite distances. in any direction to enlarge or reduce the pattern to another standard size, such as from a size 38 to a size 40.

Another object of the invention proposes constructing the grading device with a carriage movable accurate distances along a base plate and having a cross plate secured to it which contains a cross slide similarly movable along it with means to adjust the freedom of the movement of each.

As another object, the presentinvention proposes providng two spaced pattern holding arm members removably and adjustably secured to the cross slide andadapted conveniently to hold orrelease a pattern piece at any desired position with relation to the cross slide.

A further object of the present invention proposes forming the cross slide with adjustment knobs which not only will properly hold the pattern holding arm members but can also be used to lock the slide in any desired position when this is necessary or desirable.

For further comprehension of the invention, and of the objects and advantages thereof, reference will'be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the inventionare more particularly set forth.

On the accompanying drawings forming a material part of this disclosure:

Fig. 7 is a bottom plan view of the carriage shown in the several figures.

Fig. 8 is a fragmentary sectional view of one of the pattern holding arm members.

Fig. 9 is a fragmentary perspective view similar to Fig. 1 but illustrating a modification of the present invention. Fig. 10 is a sectional view taken on line 10--10 of Fig.9. f Y The pattern grading device, in accordance with the first form of the invention illustrated in Figs. 1 .to 8, inclusive, has a base plate 15, preferably made of metal, such as cast aluminum or chrome plated steel, but which may be of plastic, wood or other material.

Base plate 15 is rectangular with a dove-tail groove 16 in its upper face 17, extending the full length of the base plate.

Slidably mounted in the dove-tail groove 16 of base plate 15 is a wedge shaped carriage 18 having a rack channel or groove 19 (see Fig. 7) in its bottom face 20 and a pinion chamber or recess 21 adjacent the groove 19 in the bottom face 20. The rack channel or groove 19 extends the full length of carriage 18.

* Carriage 18 also contains a knob shaft opening 21, extending from its upper face to the center of the pinion chamber or recess 22. A pinion 23 is rotatably mounted in the pinion chamber 22 being fixed to the shaft 24 of a turning knob 25 extending above the upper face of the carriage 18.

A calibrated scale 26 is secured to base plate 15 adjacent carriage groove 16 and the carriage 18. Pointer 27 is fixed to the carriage and overlies the scale 26 for movement along the scale. A rack bar 28 is fixed to base plate 15 in groove 16. The rack bar 28 is disposed on the base plate as to fit within the rack channel or groove 19 of the carriage 18 when the carriage is slidably mounted in the carriage groove 16 of base plate 15. Rack bar 28 has teeth 29 adapted to mesh with teeth 30 of pinion 23 so that movement of the pinion by knob 25 will move the carriage along the rack bar.

Also mounted in the carriage groove 16 of base plate 15 is a carriage shim adjustment plate 31 which rests against one side 32 of the carriage. Set screws 33, extending through the base plate 15, provide means to bias the plate 31 against the carriage to thereby adjust the sliding freedom of carriage 18. Enough pressure should be provided on the carriage by plate 31 so that the carriage will stay in any desired position and the pointer will remain on any selected calibration on the scale.

Fixed to one end of the carriage 18 and to the upper surface or face of the carriage is a cross plate34. Cross plate 34 has a dove-tail groove 35 in its upper face 36 extending the full length of the cross plate. the cross plate is constructed in a manner similar to the base plate and is of the same material. The cross plate, however,has an additonal recess 37, in which is secured a rack bar 38.

A cross slide 39, wedge shaped in cross section, is

slidably mounted in the cross slide groove 35 of cross plate 34. The cross slide 39 is of similar construction to carriage 18 and preferably is of the same material. Cross slide 39 has a rack bar groove 40 in its bottom face 41 and a pinion recess 42 at one-side of the rack bar groove 40. A pinion 43 is rotatably mounted in the pinion recess or chamber 42. A pinion turning knob 44 is mounted on the cross slide. Knob 44 includes a shaft 45, which extends through an opening 46 in the upper face of the cross slide 39, and to which the pinion 43 is secured.

A cross slide shim adjustment plate 48 is mounted in the groove 35 of cross plate 34 adjacent the cross slide. Set screws 49 extend through the cross plate "48 to provide means for bringing plate 48 against cross slide 39.

A second calibrated scale 50 is secured to the upper face 36 of the cross plate 34 adjacent the cross slide groove 35 and cross slide 39. A second pointer 51 is fixed to cross slide and extends over the scale 39 for movement along the scale.

Adjustably and removably secured to the cross slide 39 by knurled headed screws 52are a pair of spaced pattern holding arm members 53. Pattern holding arm members 53 are identically constructed, each having a pluralityof spaced securing openings 54 at one end for extending or shortening purposes, and aclip type clamp 55 at the other end.

Preferably Clamps each have a lower arm 56 and an upper arm 57 which arms. are pivotally connected by hinge brackets 58 and 59 and hinge pin 60 intermediate their ends. A pair of spaced pattern holding pins 61 and 62 are secured to the lower face of each upper arm 57- and a pair of like spaced pin openings 63 are provided in each lower arm 56 to receive only the tips. of the pins 61 and 62;. A coil spring 64 around the hinge: pin 60 and between the up per and lower arms 56 and 57 biases the free ends of the arms together with the tips of the pattern holding pins 61 and 62 seated in the pin openings: 63.

The knurled headed screws 52 have shoulder portions 65 which bear against the lower arms 56 adjacent the securing openings 54 to hold the members: 53 in any desired position.

' The pattern grading: device is shown to be secured to a metal base. plate 80' formed with u-flange 8.1. A plurality of clamping screws 82 are provided along U -flange 81 for clamping. the device to a. table or other support.

The operation of the grading device is as fol-lows. A pattern piece 66, for grading a material 67, (see Fig. 4*); is. placed in the jaws of members 53' and is gripped by teeth 62. The pattern thus rests on the material being graded. The garment size is then obtained by tracing around the edges of pattern 66. When different, and larger, size patterns are desired, arms 53 are moved longitudinally by actuation of cross-slide 39 until the required size is determined oil by indicia 50. The outline of pattern 66 along the sides thereof is traced. Base plate 15 is then moved at right angles thereto. as determined by scale 26, and the pattern: size is marked: off. This composite will give the desired: larger graded pattern. In this manner, any size pattern isobtained by a single instrument.

The modification of the presentinvention illustrated in Figs. 9 and 10 is characterized by the provision of a cross slide 68 and cross plate 69 similar to cross" slide 39 and cross plate 34 described above and with like parts given the same reference numbers but primed to distinguish the figures. Cross plate 69 however,- has a plurality of screw end receiving openings 70 spaced in accor-dance with the calibrations on scale 50 and cross slide 68-has threaded screw'openings-7-1 (only one shown to receive a knurl headed screw 72 to hold pattern hold ing arm members 53' to the cross slide. A resilient ring 73 fits around: screw 72 under its head 74- normally' tohold tip' end 75' of the screwout of engagement with: cross plate openings 70 so that cross slide can move along the cross plate. Tightening the screw 72 however compresses the ring 73 and permits the tip end 75 of the screw to engage any selected one of the openings 70. The operation of Figs. 9- and 10 is similar tothat of Figs. 1 to 8, in all other respects. 7

While specific arrangements of parts and details of construction have been shown, these are for purposes of illustrationonly, and modifications may be made by persons skilled in the art without departing from the" spirit of the invention, as determined by the scope of the claims.

Having thus described my invention, What I claim as new and desire to secure by United States Letters Patent is:
