10 Claims.

Our invention is a conformator to develop a form for clothes or dress making. It is of the type in which a large number of rods mounted to slide longitudinally may be thrust in an inward direction to engage the body of a person standing in the center of the conformator.

In a conformator of the above mentioned type, one of the objects and features of our invention is the construction by which all of the rods may be moved inwardly simultaneously, the rods being mounted in a divided cabinet structure, and upright front and back sections to engage the front and back of the person whose form is being taken.

In this connection a further object and feature of our invention is moving all of the rods in each half of the divided cabinet by expansible air bags, these bags preferably being formed of rubber to thrust all the rods inwardly with a yielding type of support so that the inner ends of the rods make an outline of the form of the body of the person in the cabinet. One of the characteristics of using the expansible rubber bags is that the pressure is yielding and thus cannot injure or cause discomfort tothe person whose form is being taken.

Another detailed feature of our invention to obtain a substantially true form is mounting pivoted feet or shoes on the inner end of each rod. These shoes have a universal joint mounting to allow them to tilt to obtain a more accurate conformity to the shape of a persons body.

Another object and feature of our invention is in a positive locking or binding device to secure all of the rods on each side of the cabinet, that is, on the front and rear, so that when these are adjusted to conform to the shape of the body, all of the rods may simultaneously be locked, then the cabinet may be opened and the person whose form is being taken may step out of the cabinet.

In this connection a further detailed object and feature of our invention is providing a guide structure for the rods, this preferably being two parallel plates spaced apart and having rectangular openings for squared section rods. In conjunction with these two guide plates there is a central moving and locking plate sliding in guides, which may be shifted by a locking handle on the outside or the cabinet to slide the moving plate, which plate is provided with circular openings and engages the rounded corners of the squared section rods. This gives a clamping or friction grip. In addition to the above mentioned manner of securing the sliding rods we employ a ratchet latch which is provided with a stationary ratchet bar and apvot pawl. This pawl engages the ratchet when the rods are in their adjusted position. Then a movement of the locking arm in a sliding direction gives a longitudinal movement to a rack. This rack rotates a pinion and such pinion operates a shaft With an eccentric section. The eccentric section has a connection to a moving bar which moves transversely of the cabinet, which bar is connected at its end to one of the movable locking plates.

Another detailed feature comprises forming the l0 cabinet with a stationary and a moving section, the moving section being on the wheels and each section preferably being in upper and lower parts so that the cabinet may be disassembled into four units. By this construction the lower portions l5 may be supports and a number of dilferent heights may be provided, or the person whose form is to be taken may stand on boxes or supports of different heights.

Another feature of our invention relates to the manner of making a permanent form for clothes or dress making in which we use the shape made by the ends of the rods and the shoes thereon as a mold. In this mold we insert a rubber bag, which bag may then be lled with a quick setting material, such as a light weight mixture of plaster of Paris. The rubber bag may have small bags attached thereto to form the shape oi the arms or separate small bags may be used for this purpose. By this method we form a solid cast which has the body shape of the person whose form has been taken.

In constructing our invention, we utilize a cabinet structure 11 which has a rear section 12 and a front'section 13, there being angle tracks 14 at the bottom on which the front section may roll on the wheelszl. Each section of the cabinet has a lower part v,16 andan upper part 17. These sections are each constructed with a frame 18, which frame has vertical angle corner posts 19, longitudinal side bars 20 at the bottom and top, and cross bars 21 at the bottom and top 4connecting the vertical cornerI bars.

of the cabinet. Each section of the top is provided with an opening 23 through which extend ther neck and head of the person whose formis being taken. In the construction illustrated the Wheels l'a're mounted in the longitudinal side bars 26.

At thesides these angles are mounted on a pairof` inner angles 26, which angles have inturned anges spaced apart Vas indicated at 27 to accommodate the center sliding or locking plate 26. This plate at the bottom rests in a channel 29 and `at the top this plate is guided between two angles 30. It will thus be seen that there are two fixed plates 24 spaced apart and ,held rigidly, these plates being vertical, and between these there is the central moving locking plate 28, which'slides transversely across each of the upper sections of the cabinet.

The con-forming rods 31 are preferably square in cross section, having rounded corners 32. At the outer ends they are provided with a button 33 and at the inner end with a shoe 34. This shoe is `illustrated as formed of a metal plate 35 having a universal joint connection 36 tothe ends Vof the rods. Thisjoint is indicated as having a vertical-pivot 37 in the ends of the rods. A yoke 38 lis pivoted on thesepivots and is provided with lateral ears 39, which ears are provided with horizontal pivots 40 which engage small brackets 4l on vthe shoe plates. This provides a universal `jointallow'ing these plates to swivel on both vertical and horizontal pivots. These pivots are made fric'tionally stilto prevent the plates tilting edgewise tothe direction of travel of the rods.

The rods are moved by means of an inflatable bag 42 each upper section of the. cabinet. AThese bags at the outside bear against a vertical plate 43 and at the sidesfagainst two opposite side plates 44, these being built into the cabinet. At the top and bottom there are guide vrods 45 which have vrings 46 thereon secured to the top `and bottom of the bag. yA yflexible air hose 47 is connected to each bag so that the bags may be infiated to any desired pressure and by pressing on the buttons 33 on the ends of the rods thrust the rods inwardly. The person whose form is to be taken enters the cabinet when the front section is pulled apart from the rear sec-- tion, then with the rods thrust outwardly .and ,the bagsjcollapsed the sections of rthe cabinet are moved together and attached -byhools and eyes 48. The person may stand on a box or pedestal so that his neck will extend through the opening 23 with the head above the cabinet Vand the shoulders inside of the cabinet. The shoulders should be belowthe upper row of rods. These rods 31 are Cover panels.V 22 may be utilized to enclose the sides and top shoes will tilt to conform to the angle at which the 'rods meet the body, and as the rods are guided in a rectilinear movement they cannot twist or turn on account of being square. The rubber bags, therefore, give a resilient support to the rods and apply pressure so gently that they will not injure or discomfort the person whose form is being taken.

The locking arrangement utilizes a fixed straight ratchet 49,y which is secured to the lower longitudinal side bar 2O of theupper section 17 of each cabinet, this ratchet bar preferably tting on the upper edge of suchside bar. A guide block 50 .is tted in the angle of the angle bar; This has a vertical section 51 and a horizontal section 52. The vertical section is provided with a guide groove 53, from which extends a longitudinal slot 54. A cylindrical handle bar 55 extends through f this slot and has a handle end 56 on the outside of the cabinet. The inner end of the rod connects to a rack 57, which rack has a base 58 slidable in the groove 53 and has ya toothed section 59 extending outwardly through an opposite groove 60 in the vertical section 51 of the block 50. A pawl 61 has a hub 62 mounted on the rod 55. It is provided with a tooth 63 to engage the straight ratchet 49. A finger-operating end 64 extends outwardly through a slot 65 in the side panel 22 of the side section v17 of the cabinet. The end, therefore, may be engaged by the fingers when all of therods have been thrust inwardly to their full extent, this tilting the pawl until the tooth engages with the ratchet 49. Such construction is used to hold the rack 57 in its locking position, but prior to engaging the pawl with its ratchet the handle 56 is thrust inwardly toward the center or junction line of the cabinets. The rack causes a rotation of the rack pinion 66 which is mounted on a rotatable cam shaft 67, one end 68 of which shaft 67 is journaled in the end 52 of the block 50 and thevother end in a bearing 69 in the top of the cabinet secured to the top longitudinal side bar y20. A cam or eccentric section 70 of this shaft operates through cam slots 7l in a series of transverse slidable bars 72. These bars extend through slots 73 in one of the xed guide plates 24 and are attached, preferably, by an angular bent end as indicated at 74 to the slidable locking plate28. Therefore, the cam or eccentric section 70 causes a lateral or cross movement of the plate 28. Plate 28 has circular open'- Aings 75 surrounding each of the rods, and Ythis forwardly sufciently for the model to step out of the cabinet. A base block 78 is fitted across the lower end of the mold and is supported on the stationary section of the cabinet, such mold being designated generally by the numeral '79 formed by the shoes on the ends of the rods 31. A rubber bag 80 is iitted in the mold. This bag has a bottom 8l which rests on the block 78 and a neck 82 which extends through the opening 23. The bag is then iilled with a quick-setting composition 83 which may be plaster of Paris incorporated with some material giving body but having light weight. This sets quickly after forcing the rubber bag into close contact with all of the shoes. In order to mold the arm sections, the rubber bag may be made with small rubber bags forming the arms connected thereto, or these may be molded separately. It is, however, preferable to mold the body form and arm forms together, then on separation of the cabinet these may be taken out of such cabinet as a unit. The rubber bag is provided with a lap or equivalent joint 84 which is provided with fasteners. The portion of the bag forming the arm is also provided with joints 85 having fasteners. 'This allows the rubber bag to be readily taken off the form and it may be used again. This leaves the plaster form with the arms attached. These arms may then be disconnected when it is desired to fit clothing on the form.

An important and characteristic feature of our invention is that the inatable rubber bags give not only a resilient pressure of the rods against the body of the model but that this pressure is equal on all parts of the body against which the rods press and also at all positions of the rods, whether the person is thin or stout. The yielding air pressure in the air bags can be adjusted so that the rods will not press in on the soft or more yielding parts of the body. Thus, a true natural form may be obtained.

The lower section 16 of the cabinet is secured to the upper part 17 by means of pins 76 secured to one of the side bars 20 at the top of the lower section extending through a slot 77 and the side bar 20 on the upper section (note Figs. 2 and l0).
