SKIRT MARKER Filed March 19, 1947 ATTORNEY m 36 M 57 f\\\\\\\\\\\\\\ lNVENTOR ZRGoZdsiein Patented Dec. 5, 1950 UNITED STATES PATENT QFFICE 3 Claims.

This invention relates to improvements in skirt markers. My present invention is directed to the class of skirt markers wherein the hem line of a skirt may be outlined while the skirt is being tried on by a prospective wearer, using as a gauge, the distance from the floor to the desired hem line, the wearer moving relatively to a contrivance pointed at the desired hem line on which chalk or some similar fugitive marking material is applied. More frequently, the skirt markers involve a blower or aspirator operated by a pneumatic device, such as a bulb, which blows a stream of chalk to define a fine line at the desired level of the garment.

Such. contrivances, under the care of an inexperienced salesgirl, frequently lead to undesirable effects, especially where the stand supporting the marking element is not held vertically, or is tilted in the process of marking for various reasons. The resultant effect is to eject a stream forming a marking line which is not regular, causing error in the final work.

It is contemplated by my invention, and it is an object thereof to provide, a skirt marking device which pneumatically ejects marking material, such as powdered chalk, in a fine line outline and which assures against the likelihood of tilting or swinging of the standard or support, and includes means to control or modify the ejection of the marking material or air-suspended powdered chalk unless the marker has been maintained in a level position.

Still more particularly it is contemplated by my invention to provide a skirt marker which includes valving means, controlled by a plumb lever arm, which automatically cuts off the supply or flow of marking material should the device be tilted from a predeterminedly set position.

It is contemplated by my invention to provide a skirt marking device in which a regular hem line may be outlined, eliminating the likelihood of error in applying the line defining charge, by maintaining valving means operative only when a predetermined set hem line defining position is maintained.

To attain these objects and such further objects as may appear herein, or be hereinafter pointed out, I make reference to the accompanying drawing forming apart hereof, inwlnich Figure 1 is a longitudinal sectional view of a skirt marker in accordance with my invention;

Figure 2 is a section taken on the line 2 -2 of Figure 1;

Figure 3 is a fragmentary View taken in the direction of the arrows 33 in Figure 1;

Figure l is a perspective view illustrating my device in use;

Fi ure 5 is a cross sectional view of another embodiment of my invention;

Figure 6 is a fragmentary section on the line 5-5 of Figure 5.

Making reference to the drawing, it is contemplated by my invention to provide a skirt marker in comprising a standard ll, vertically supported on a base l2 and including provision for indicia 3, to show the relative distance of the hem from the floor. In accordance with my device, I provide a casing [4, including a guide it, through which the standard ll may pass. A set screw 16 may be employed to position the casing along the length of the standard. The casing is provided with a chamber H, which may be filled through a screw cap l8 at the bottom thereof. A tube 59 is screw threaded in the partition walls at and 2|, defining a mixing chamber 22.

The upper end of the tube has affixed to it rubber tubing 23, leading, to a suitably valved bulb 24, for directing a blast of air into the tube 59. The end 25 of the tube leads into the chamber ll. Its relative position from the bottom. of the chamber ll may be adjusted by the pro-vision of external screw threading 26, directed through a boring 2? which is similarly threaded to receive the tube. A look nut 28 may be employed to predeterminedly fix the relative position of the tube within the chamber [1.

The chamber ll is provided with an outlet 29, leading to the mixing chamber 22' previously described. Egress from the chamber 22' is afforded by the passage 30 leading to the nozzle end 3|.

In accordance with my invention, the mouth of the passage 38 is provided with a substantially spherically outlined seat 32, closed by a valve 33 which is generally spherical in contour and in.- cludes a diametrically directed port 34 which may be aligned with the passage 30, to connect the chamber 22 and the passage 30. When the port 34 and the passage 30 are aligned, direct egress; is afforded.

In aco-rdance with my invention, I supply the valve 33 with trunnions 35, 35, passing through bearings 36, 36,111 the casing, to direct keying ends 3''! into the ball-shaped valve 33, to cause positive rotation of the valve 33 with the keying ends 31, while permitting pivotal movement of the trunnions in the bearings 36, 3B. The trunnions merge into a downwardly depending ridged arm plumb compressing a loop 38, which may have the depending arms and lower branch 39 clear the chamber l l at its sides and bottom.

I prefer to weight the ridged arm plumb or loop 38 so that normally it will remain in a vertical position. Any tendency of the standard II to tilt in any direction will maintain the weighted loop in a vertical position. Such swinging action, it will be observed, will result in the port 34 being disaligned with respect to the passage 30.

In operation, should chalk 59 be blown into the mixing chamber 22 by the operator, egress of airsuspended chalk will be possible only when the port 34 and the passage 39 are in alignment. Any tilting backward or forward will automatically retain the loop 38 in a vertical position, and relative movement of the standard thereof will serve to shut 01f the supply of chalk through the passage 30.

It will be observed that I provide the outlet 4| of greater dimension than the inlet port 34, in order to get a wide distribution in a horizontal direction while retaining a fine line vertically.

Any tilting of the standard sidewise will become apparent to the operator because of the increase in the vertically outlined width of the deposit. Thus forward and backward displacement of the standard from the vertical would become apparent by reason of a lack of deposit, thereby distinguishing from prior constructions known to me where a displaced vertical alignment is not detectible.

It will also be observed that while I have illustrated a valve 33 which is gravitationally pivoted on its seat by the loop 38 into aligned position longitudinally along the length of the nozzle, I may provide a universal bearing so as to cut off or taper off the supply, should any tilting of the standard occur.

For this purpose, in Figures 5 and 6, I show another embodiment wherein housing walls 42 are formed with arcuate cutouts 43 in a vertical plane, having angular displacement of about 30 above and below the horizontal. Should there be any sidewise tilting, the gravitationally weighted loop or rigid arm plumb will pivot on the seat 92 of the ball shaped valve 33, to arrange the flat port at an angle to the passage 39, thereby tapering off or attenuating the passage and giving an indication to the operator that the leveling of the marker on its base should be effected. I may however arrange the port 30a and entrance to the passage 3% eccentric, so that any vertical displacement of the standard will disalign the passages and limit the supply of the charge to the nozzle.

It will be understood that while I may make the casing 29 and the chamber ll of integral construction, such as by casting or moulding the same, I may make the chamber i'l separable, as illustrated and aflix the same to the body Id of the casing by suitable attaching means, such as a screw threaded throat or by bayonet slot construction.

It will also be observed that while I have made the gravitationally pivotal loop or plumb arm 38 of a single l ngth of material, such as wire, depending on the weight of the wire to efiect gravitational alignment to a vertical position, it will be understood that the weight of this material 4 may be augmented to increase the sensitivity of movement.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent, is:
