24 of housing 21 and is journaled at its lower end in bearing 52 carried by the base plate 20. Shaft 51 is provided at its upper end with a hand wheel 53 whereby shaft 51 may be manually adjusted. Shaft 51 has fixed thereon an upper small gear 54 and a lower large gear 55. Upper gear 54 meshes on the inner side thereof with an elongated gear rack 56 fixed to sleeve 38 and an outer gear rack 57 is fixed to connecting bar 31 and meshes with the outer side of gear 54. Lower gear 55 has meshing therewith a lower elongated gear rack 58, which is fixed between the lower sleeves 42.

An outer lower gear rack 59 is fixed to connecting member 35 and meshes with the outer side of gear 55. A pointer or adjustment indicator 60 is secured to upper gear rack 56 and movable longitudinally of housing 21. A second pointer 61 is connected with a gear rack 62 slidable in a housing 63 which is fixed to a sleeve 64. Sleeve 64 is loosely disposed on upper shaft 26 adjacent gear 28'. Pointer 61 indicates the vertical adjustment of the blank sheets, whereas pointer 60 indicates the longitudinal adjustment of the blank sheets.

A master pattern or templet 65 is firmly held in spaced relation relative to the base 20 by means of a clamping member 66. The master pattern or templet 65 is adapted to overlie a series of blank sheets which are clamped in the clamping jaws 47 and 48. The clamping jaws carried by the rack bars 37 are the lowermost jaws, whereas the clamping bars carried by the rack bars 45 are the upper or top clamping bars. The clamping bars or jaws carried by rack bars 41 are the jaws immediately below the top bars 45, and the clamping jaws or bars carried by rack bars 35 are next to the bottom clamping jaws.

In the use and operation of this machine, a series of blank sheets of initially rectangular configuration are disposed in superposed relation and are substantially larger in size than the master pattern or templet 65. The

indicators

60 and 61 are initially disposed at zero position when the blank sheets are secured in the clamping members 46. The pairs of rack bars are then adjusted longitudinally by turning wheel 53 clockwise to shift pointer 60 substantially 1. With adjustment of wheel 53, gear 55 will move rack 58 to the right and rack 59 to the left. At the same time rack 56 will move to the right and rack 57 to the left. Due to the smaller diameter of gear 54 as compared to gear 55, the gear racks 56 and 57 will be moved in opposite directions a shorter distance than racks 58 and 59 are moved by gear 55. Hand wheel 28 is then adjusted counterclockwise to move pointer 61 downwardly 1". When hand wheel 28 is turned counterclockwise the gear racks 37 and 45 will be moved in opposite directions at right angles to the

racks

56, 57, 58, and 59. As

racks

37 and 45 are moved by rotation of toothed shaft 27, shaft 26 will move

racks

33 and 41 in opposite directions for a lesser distance than the movement of racks 56 to 59. The templet 65 remains stationary, and when the several pairs of rack bars with clamps are adjusted as shown in Figure 2, the blank sheets will be shifted after the manner shown in Figure 2. A first cut is made, as indicated at 67, in the shifted blank sheets. A second cut is then made in the blank sheets after the blank sheets have been shifted as shown in Figure 3. The second shifting of the blank sheets is made by adjusting hand wheel 28 an additional space downwardly, while hand wheel 53 remains stationary. The second cutting is then made along the templet line 68.

A third cut 69 is then made in the blank sheets after these sheets have been adjusted to the positions shown in Figure 4. This adjustment is made by a horizontal adjustment and turning of wheel 53 to shift pointer 60 to the right two spaces. Hand wheel 28 at this time remains stationary. A fourth cut 70 is made in the blank sheets after the blank sheets have been shifted to the positions shown in Figure 5. At this time, pointer 60 is to the left of zero. position, and pointer 61 is in the same position as shown in Figure 3.

If the pattern is to be varied as to the length of the garment, a fifth cut is made along the line 71 after a further longitudinal adjustment of the blank sheets.

When the now cut blank sheets are returned to their original positions, these blank sheets, which are now pattern sheets, will be disposed as shown in Figure 6 necting said members in pairs, means adjusting said members longitudinally of said housing, and means adjusting blank sheets cannot shift after being adjusted. With a machine as hereinbefore described, any number' of patterns may beformed from an'initial master pattern,

and the forming of these additional patterns can be made quickly, so that these additional patterns will be made at a relatively small cost. Where the additional patterns are designed for garments which are to be made larger only above the waist or body portion, without enlargement as to length, these patterns can be easily formed by eliminating one or more steps hereinbefore described- Having thus described the invention, what is claimed is: 1. A pattern machine comprising a housing, a templet clamping means fixed to and extending from said housing,

a plurality of blank sheet clamping members, means consaid members vertically of said housing.

2. A pattern machine comprising a housing, a templet clamping means fixed to and extending from said housing,

1 a plurality of blank sheet clamping members, means connecting said members in pairs, and means adjusting said pairs of clamping members relative to each other.

3. A pattern machine comprising a housing, a templet clamping means fixed to and extending from said housing, a plurality of blank sheet clamping members, means connecting said members in pairs, means adjusting certain ones of said pairs of clamping members in one direction, and means adjusting certain others of said clamping members in a direction at right angles to said one direction.

4. A pattern machine comprising a housing, a templet clamping means fixed to and extending from said housing, a plurality of blank sheet clamping members, means connecting said members in pairs, and means adjusting certain ones of said pairs of clamping members in one direction while simultaneously adjusting certain others of said clamping members in the opposite direction.

5. A pattern machine comprising a housing, a templet clamping means fixed to and extending from said housing, a plurality of blank sheet clamping members, means connecting said members in pairs, means adjusting adjacent pairs of clamping members in one direction while simultaneously adjusting the remaining adjacent pairs of clamping members in the opposite direction.

6. A pattern machine comprising means firmly securing a templet in fixed position, means holding a plurality of superposed blank sheets beneath said templet, andv means adjusting said blank sheets relative to said templet and to each other.
