Briefly described, my device as shown in the drawings issimilar to a device shown in my copending application Serial No. 55,737, filed December 23, 1935, and is for a similar purpose.

'Heretofore, ladies hosiery has generally been fitted according to foot size, and although attempts have been made to supply hosiery in various' lengths, insofar as I am aware no means has been provided for quickly and accurately determining the height to which a stocking will reach when fitted to the leg of a person in advance of 5 an actual fitting. Hosiery will shorten when fitted to a leg according to the size of the leg; that is, the larger the leg in diameter at the calf the greater the stocking will shorten in length, and the smaller the leg in diameter at the calf, .10 the less will be the shortening. Obviously foot size has no relation to the diameter of the calf of the leg, hence a person with a small foot not infrequently has a large calf and a long leg or vice versa. If the leg islong and large there is a difierent degree in the shortening of the stocking when fitted than when the leg is long and slender. With my device, it is possible to quickly and accurately determine the exact height to which a stocking will reach on any leg irrespective 7 of the variations, whereby the operator may readily supply a stocking that will reach the desired height prior to an actual fitting, thereby efiecting a material saving in time, labor and expense and insuring against possible error in result.

In detail the device shown in Figs. 1 to 8, comprises a vertical tubular standard I, preferably square in cross section and of relatively light sheet metal, and an upper tubular post 2, also square in cross section and telescopically slidable Within the standard for vertical extension from the upper end of the standard, while a tubular base stem 3, square in cross section, is telescopically slidable in and out of the lower end of the standard.

Post 2 is provided at its lower end, with resilient fingers 4 formed from the opposite side walls of the post adjacent the lower end thereof to project slightly outwardly and then inwardly so the outwardly projecting portion will frictionally engage the inner sides of the standard for frictionally supporting the post at any desired degree of extension from the post, while the shape of the fingers permits ready insertion of the post within the standard in case it is com pletely withdrawn therefrom, or for assemblage of the device.

A horizontally disposed fiat plate 5 is secured to the upper end of post 2 by any suitable means, such as a stud bolt 6 engaging in a filler block I, 50 that is brazed or soldered in the upper end of the post. The plate 5 is formed to generally crescent shape at 8, as seen in Fig. 8, where it projects from a side of the post so that when the post lies alongside the leg of a person, the crescent shape .55

outline of the edge of portion 8 will substantially conform to the horizontal contour of the leg. The opposite end of the plate is turned upwardly at 9 and apertured at E6 for suspending the device from a suitable hook.

The stem 3 is provided at its lower end with an elongated base plate II of generally T shape, the end of the leg extending across the bottom end of the stem and the arms disposed outwardly of the same side of the device as the crescent shape portion 8 of plate 5 extends. The plate It is rigidly secured to a filler block I2 by a screw l3, which block is soldered or welded into the lower end of the stem, although it may be brazed or soldered direct to the lower end of the stem or secured in any other suitable manner to hold it rigid with the stem and against turning relative thereto.

Enclosed within stem 3 and extending upwardly above the upper end of the stem into standard I is an expansion coil spring I4 adapted to engage at its upper end against a block I5 secured within the standard by a pin I6 or other suitable manner, and at its lower end the spring engages against the lower closed end of stem 3 or filler block I3. One side of stem 3 is vertically slotted as at I l to pass the end of a screw I8 that threadedly extends through a reinforcing boss I9, and one side of standard I adjacent the lower end of the standard and to Within the slot H, but not sufiiciently far to interfere with the free compression of. the spring. The spring I4 is slightly under compression when the wall of the stem closing the upper end of the slot I! is in engagement therewith and the stem is fully extended as indicated in the drawings. This construction, as described above, permits the use of a long spring, thus enabling ease of operation and also permitting a considerable extension of plate II from the lower end of the standard for a purpose later to be described.

The side of post I opposite the side of the device from which the base plate and crescent shape member 8 project, is graduated by horizontal lines at inch intervals commencing from about the plate 5, each line graduation being numerically marked with a whole number of successively increasing value below each line commencing with the numeral 23 at the upper end of the post and from thence downwardly, as indicated at 20. These lines and numbers are inscribed in the metal and preferably filled with a suitable-contrasting color to be readily seen and which also precludes any chance of the lines or numbers becoming effaced by continual sliding of the post in and out of the standard.

The upper end of the standard on the same side as the indicia 20 is cut away at 2| so as to permit the number for the line it designates tobe visible for reading when the line is even with the top end of the standard, as seen in Fig. 2, and also, when the post is fully collapsed within the standard for the shortest measurement, the numeral 23 adjacent the plate 5 is visible for reading.

On the same side of standard I, and spaced a distance below the cut-out or recess 2!, about equal to the vertical distance of two adjacent spaces between alternate graduation lines, a rectangular opening 22 is provided so as to expose the numeral two graduations below the one appearing in the cut-out 2!, and at the same time directly below opening 22 is another rectangular opening 23 formed in the wall of the standard, but spaced from opening 22 a distance about equal chaser stands firmly on the floor 33.

to that between adjacent graduation lines on post 2. Consequently upon sliding post 2 upwardly or downwardly within standard I, three of the in dicia or graduation numerals will simultaneously appear in cut-out 2i opening 22, and opening 23, respectively.

The cut-out ZI is indicated by the letter S inscribed in standard I'directly below the cutout, and openings 22 and Y23 are respectively marked M and L, these letters indicating small, medium, and large.

On the side of the device opposite the indicia above described, the standard I is inscribed with horizontal lines one inch apart commencing at the lower end of the standard about one inch above the upper side of a horizontally projecting arm i lrigidly secured at one end to the lower end of standard I by a square collar 25 that is brazed, soldered or riveted to the lower end of the standard. This arm is turned up slightly at its outer end, as indicated, and projects from the same side of standard I as the base plate II projects from side of stem 3.

The inch graduations are suitably numbered immediately below each line commencing with the numeral 1 at the bottom and terminating with 20 at the upper end of the standard one inch below the upper end thereof.

The side of standard l is cut out or recessed at 26 on the side bearing the inch scale in the same manner as and directly opposite the cutout 2i. On the outer side of the post adjacent the cut-out 23 are inscribed horizontal lines an inch apart and positioned directly opposite the lines inscribed on the opposite side of the post. Numbers are inscribed below the lines on the side adjacent the cut-out 26 commencing with 21 at the top of the post and increasing in value downwardly along the post, as 21, 22, 23, etc. These graduation lines and numbers are indicated on the drawings at TI and it will be noted that the indicia 21 are two digits lower in value than the indicia 23 appearing on the opposite side of the post, and that the number appearing in cut-out 26 will always represent the actual distance between the upper side or arm 24 and the plate 5 and no other numbers will appear through the side of. the standard adjacent cut-out 23 except the one appearing through said cut-out.

The stem 3 is also inscribed with three horizontal vertically spaced lines at 2B and the upper line being adjacent the lower end of standard I, and marked L and the others in descending succession being marked M and S. All three will appear when the stem 3 is fully extended and these indicia may appear on the three imperforate sides of the stem or only on one of the three sides, if desired, but preferably on the sides extending parallel with arm 24.

In operation, the operator first places the device horizontally and measures the calf of the leg between arm 23 and base plate I I. The result may indicate M or medium on the scale on stem 3. The device is then placed in upright position with the base plate I I on the fioor. The foot 33 of the purchaser is then placed over the arm 24, with the arm fitting across the instep and the standard will move downwardly, compressing spring !4 according to the height of the heel 3i of. the purchasers shoe, the arm 24 always being firmly in engagement with the instep, and the leg 32 being straight, since the pur- The post 2 is then moved upwardly to the height X that the the floor. ameter, will automatically slide into the instep purchaser desires the stocking to reach. The

operator then observes the indicia appearing in 'opening 22 in standard I, which in the case illustrated, indicates 30, meaning that a stocking thirty inches from instep to top will be requircd to reach that height on the leg although the actual distance between the arm 24 and line X is'26 inches. Had the scale 28 indicated S, or small, a 28-inch stocking would reach the height'indicated at X, the numeral 28 being the one appearing in the cut-out 2| and had the scale 28 indicated L, then a 31-inch stocking would have been required. All these figures simultaneously appear through the side wall of standard I and are instantly readable, hence the proper length stocking can be instantly'determined for any size leg without further manipulation than elevating the plate 5 to the height desired.

The provision of square tubing for the post, standard and base plate, insures against turning of one part relative to the other and it also furnishes a surface for the proper scales. The base plate H being of the shape described will clear the heel and sole of the shoe so the operator will not stand on the plate, but can stand firmly on Arm 2%, being of relatively small diof the shoe and will firmly be held there.

In the device of Figs. 9 to 14, the upper telescopic post 2' is provided with three separate sets of indicia, each set comprising three adjacent zones of vertical length respectively indicated S, R and ,L, meaning small, regular and large. These markings are arbitrary as '2', the zone marked S being uppermost, the zone B next below and adjacent thereto, and

the zone L being lowermost and adjacent zone The upper end of the standard I is marked A, B and C, there being no openings or cut-out portion as in Figs. 1 to 8. When the post 2' is received within standard I the letters A, B, C are respectively on one of the three sides of the standard I so that A is on the same side as one of the sets of indicia and C is on the same side as the third set of indicia.

On the standard 1' is a vertically slidable gage element comprising a square collar 4!! vertically slidable on standard i to various heights and to which collar is secured a pair of horizontally extending arms M, 2 projecting from the blank side of standard 5.

The arm i! is formed with a right angle guide member t3, which guide member is a fiat strip of material folded over at its upper and lower edges to provide a channel at the top and bottom edges of the strip for slidably receiving opposite top and bottom edges of a right angle extension M of arm 42 for movement of the arm M, 2 toward and away from each other relatively. The guide member 53 extends horizontally past the collar at opposite ends, as seen in Figs. 10 and 11 and is inscribed at predetermined horizontally spaced points with the letters A, B, C, while the extension 44 is marked with a line 45 adapted to register with the letters upon sliding extension 44 horizontally on the guide strip.

In actual practice the foot of the person desiring to purchase hosiery is placed on the arm 24 with the instep engaging over said arm in the same manner as described for Figs. 1 to 8, and then the gage element is raised and the arms moved together so as to touch the sides of the leg, front and back, at the thickest point of the calf. The operator then moves the upper teleing that stocking in order to reach the height on the leg indicated by the plate 5' must be size CL stocking.

It will be seen that the zones marked on post 2 are so arranged that for a C size calf and 'for an A or a B size calf, there is a considerable variation in the length necessary to reach a predetermined uniform height, since a small or S length stocking may be required for an A of very small calf, whereas for the same de sired height on a C size calf an R or a regular" length stocking may be necessary. Also for all sized calves an R. length stocking may be the correct length depending upon the height the person desires the stocking to reach.
