To all flu/om it may concern:

Be it known that I, ARTHUR MATTHEY, engineer, a citizen of Switzerland, residing at Vevey, Canton of Vaud, in the Confederation ol Switzerland, have invented certain new and useful Improvements in Dressmakers Adjustable Dummy-Supports, of which the following is a specification.

The object of the present inventionis the provision of an adjustable dummy-support for tailors and dress-makers shops and for the purpose of exhibiting clothing in showwindows.

Dress-makers dummy-supports heretofore in use were not adapted to keep the dummies in an exact vertical position owing partly to an inexact adjustment of the supporting rod held within the pedestal and owing partly to the manner of maintaining the dummy on the said rod at different heights.

According to the present invention however the dummy support consists of a supporting rod extending through the dummy and held within a pedestal shaped so as to avoid the unevenness of the ground and provided with at least one bushing for securing the vertical position of thel rod and of a device for adjusting a dummy supporting plate at different heights and at a right angle to the axis of the rod.

In the accompanying drawing several working examples of the invention are shown.

Figure l is a general side elevation of a dummy-support partly in section.

Fig. 2 shows on an enlarged scale an adjusting device for the plate.

Figs. 3 and 4 are sections showing two diierent ways of fixing the supporting rod within the pedestal.

Figs. 5, 6 and 7 are sections showing three modified forms of the base ring of the pedestal.

Figs. 8, 9 and l0 are vertical sections of other forms of adjusting devices for securing the dummy at a desired height.

Fig. l1 is a general side elevation of a support for short dummies for blouses.

Fig. l2 shows a sectional view in full size of a device for adjusting the length of the telescoping tubes from above the dummy, and n Fig. 13 is a section of a similar device for adjusting the height of the dummy on the rod from beneath the dummy.

Like characters of reference indicate corresponding parts.

According to Figs. l and 3 the pedestal of the dummy support is cast in metal and comprises an annular bottom piece a and two bushings al, a2, placed one above the other, and which are connected to the bottom piece by three legs o3, at, the whole forming a piece wherein any objectionable tension from an unequal cooling after casting are avoided, and also one which may be easily bored on a machine so as to have the axis of the bores standing vertically on the base ring. Within said bushings a rod b extending through the dummy is secured in a vertical position and the dummy c itself is sleeved on said rod by means of an upper plate c1 and a lower plate 02, the latter resting on a disk Z1 made in one piece with the sleeve d and fitting the rod t (Fig. 2). The sleeve Z is provided on its outside with a conically turned-oit thread Z2 and with several radial slits cl3. It is also iitted with a hand-wheel e forming a nut in which the thread e2 is cut only on a part of the bore, so as to lea-ve the remaining part of the bore with a diameter corresponding to the inner diameter of the thread e'. This cylindrical part of the bore is then turned conically, as shown in Fig. 2, where the diameter at e3 is somewhat greater than at et so as to form a cone similar to that of the thread d2. The nut e when being screwed up on sleeve cl by means of the milled handle el will therefore clamp said sleeve fast to rod b and will maintain the dummy at any desired height by means of the disk Z1 per face of which stands at a right angle to the axis of the rod Z), and as the latter is kept in a vertical position by the pedestal the dummy must necessarily also be kept in a vertical position.

According to Figs. 3 and -l the rod may be a pipe fixed within the pedestal either by being sleeved within the upper bushing and screwed directly into the lower bushing or by being sleeved within the upper bushing and being sleeved on a pin 61 iixed to the pipe and screwed within the lower bushing'.

Also the bottom piece a may be shaped either as is shown in Fig. 5 or as is shown in Fig. 6 with a narrow rim to avoid as much as possible the unevenness of the surface upon which it rests, or as is shown in Fig. 7, this annular bottom piece may be prothe upvided with three or more rubber feet c5 to secure a safe and yielding contact with the supporting surface.

In order to render the dummy-support well adapted for show-windows the rod may be replaced by two telescoping tubes as shown, the relative position of one of the tubes with regard to the other being arranged so as to be moved from the top of the dummy.

In Figs. S to 12 are shown severaly forms of contrivances to accomplish this purpose.

The simplest form is shown in Fig. 8 where the hollow rod Z) extends only into the space between the upper plate c1 and the lower plate 02 and is provided at its top with a nut 712 fixed to it. A handle g is fixed within the top plate c1 by means of a collar g2 and is fitted with a rod projecting downwardly and screwed by means of a threaded part into a nut Z22. By turning the handle G the dummy may be fixed at any desired height determined by the position given the rod within nut b2.

Figs. 9 and 10 represent two other forms of contrivances for adjusting the height of the dummy by turning the handle g. In Fig. 9 the handle is made in two parts; lower part go is fixed by means of a collar g to the plate c1 of the dummy in the same manner as that shown in Fig. 8, and a movable upper part g rests on the lower part with the faced part of a disk-like nut g1 fast to the upper part. The handle part go by means of the collar g2 is secured to a tube h which is sleeved within the tubular Vrod b. The end of the tube L engaged within the rod Z.' is split into several branches 7b2 and is provided with a conically shaped inside portion tapering toward the top and fitting a conical piston fixed to the lower' end of a rod the upper end of which is threaded as indicated at f1 and fits the nut g1 of handle g. By turning this handle while holding fast to the part go the rod will be either screwed into nut g1 whereby l the piston f2 by moving upward will cause the end of the tube L to be spread and to be clamped fast within pipe Z), or will be unscrewed from the nut g1, and the piston f2 while descending will leave the conical inside surface of the tube /zy thereby freeing the tube 7L within pipe rlhe raising o-r lowering of the dummy c will therefore be effected by taking hold of the part go and by turning the part g in the one way or the other to clamp or unclamp tube zy within pipe I).

The same effect may also be obtained by the structure shown in Fig. 10 in which the handle g is iixedto the sleeve g-2 the plate c1 and the rod f, and by fitting the lower end of rod f with a threaded part f1 to engage the piston f2 like a nut. In Fig. 9 are also shown feet a5 cast on to the underside of the annular piece a of the pedestal as means for avoiding the effect of the unevenness of the ground or other supporting surface..

Figs. 11, 12 and 13 relate to a form of the support adapted' for short dummies for blouses or for exhibiting corsets in showwindows, Fig. 11 showing a general view or the contrivances shown in detail in Figs. 12 and 13.

As illustrated Fig.- 11 a. metallic footplate a is provided with a hub al wherein rod B reaching into the space between plates 01 and c2 of the dummy is fixed rigidly by means of a threaded part and pins set crosswise.

A tube 71 fitted at its top end with a hollow handle g made fast to the plate clp and provided at its bottom end witha clamping or braking device, is made to telescope with- 4in the rod Z) thus forming an extension of the same. rFliese devices are worked with one hand by holding fast the handle and bypressing with the thumb on a movable knobv f5 projecting from the top of the handle. By pressing it the rod may be lengthened or shortened at will; by letting go again the telescoping tubes will be automatically clamped fast to one another' at the desired length. The plate c2 normally rests upon the flanged part m of a cap which is also provided with an intermediate conical part m2 fitting over a sleeve Z loosely mounted on the rod b and with which are also associated frictional devices hereinafter described in connection with Fig. 13Y for normally supporting the dummy formin any desired position on the rod b.

In Fig. 12 which represents the clamped position of the device Vthe'knob f5 is guided vertically within the top part of handle g and is linked with two similar arms f8 to two slides f4 fitted on a horizontal pin fast inthe insideV of-t-hehandle., Said. slides f4 are linked again by two Varms f8, of equal size to a knob f6 fixed to the top-end of a wire f which is thus held coaxially with a knob f5 andis connected to the bottom plate f7 of. a cap f3 containing the clamping or braking device. The inside of cap f3 is provided with a conical yportion fitting with some play to a conical'piece 71,1 secured to the end of tube 7L and is kept concentric'with it by means of a set of frictionballs z' seated within the walls of cap f8. Then the knob f5 is at rest end piece h1 and the balls e' will be kept in Contact with each other by a spring k inserted between4 bottom-plate f7 and the piece 71,1, andrthesprings is strong enough to cause the cap f3 to wedge the balls fast between the conical endA piece 71B: and the rod b, and to brake the balls z' completely soas t0 clampzthe piece k1- fast within rod 5. If; however', the knob f5 is pressed down the spring 7c will be compressed. andthe cap f3 will carry the balls z' upward thereby releasing the contact of said balls with the conical surface of piece h1. By this action the pipe L is free to move in either direction relatively to the rod band the balls z'- roll freely on the inside surface of rod According to Fig. 13 which also shows the device in a clamped position, a cap a provided with a flanged part m1, supports the plate 02 of the dummy, and its intermediate conical part m2, contacts with a set of friction balls e' seated within the conically shaped part of the wall of an inner sleeve Z. This sleeve Z is fitted with some play on rod and is pressed upward by a spring 7p inserted between a shoulder of the sleeve and a flanged part of an extension ma of the cap. The pressure of this spring is suflicient to clamp the balls fast between rod b and cap n and to support the weight of the dummy. If however the counteracting weight of the dummy be removed either by lifting the same up from the anged part m1 or by lifting up the extension of the cap the clamping action of the spring is diminished so that sleeve Z may be easily shifted on rod b in order to fix the dummy automatically at any desired height after releasing either the dummy or the extension.
