l1 Claims.

My invention relates to dust protection devices or guards.

In respect of show windows, or the like, the problem of protecting the goods-displayed from dust is one which has proved troublesome. The

.greatest source of dustis from the spaee'between the ceiling and the flooring about where dust .may rest'thickly on the upper surface of the ceiling. It is well knownthat because the reectors used, for example in lighting from ceilings do not t closely as a general rule with the rings upon which theyare supported in the ceiling, endless dust seeps-through the gaps between the 'reectors and the supporting rings, particularly .when doors are opened causing suction to lift :the dust oi the upper portion of the ceiling.

Only-a merchant who has displayed expensive `light coloredga-rments, such as ermine-evening wraps, white silk evening gowns, etc. can fully .appreciate this trouble from 'above the ceiling.

An object of the invention isto provide means -f0r sealing `oif suchdust'from the show window.

By my invention in its-preferred 'form I have provided an asbestos ring made of strands of asbestos and held togetherl by wires with lhooks andv eyes at the terminals of the wire, which Vring may be used to seal ofi the dust which otherwise would pour from above the ceiling around the lamp reectors.

`Another object has beenthe provision of such a device which is light, incombustible, inexpensive to produce andsimple to install.

Other objects and advantages will be more apparent hereinafter.

My invention may be best understood by reference to the accompanying drawing in which:

Fig. 1 is a vertical section showing the lighting means in'positon in a ceiling and the dust protection means or -guard applied thereto;

Fig. 2 is a plan View of the supporting ring and 1 a reflector supported on the ring illustrating the common lack oi"v registration between said means and the opportunity of dust penetration;

Fig. 3 is aplan View of the dust protection K,

means or guard;

Fig. 4 is an enlarged elevation of a section of the guard; and

Fig. 5 is a section on the line 5-5 of Fig. 4.

The preferred form of my invention which has g;

provided with shade or reflector holding means M for a reilector I5.

I lhave discl'osedin-m-y-invention a common standard-form of reiiector I5V having .an eccentric bottom edge Itproviding an eccentric opening. The reflector is adapted to be supported in the form shown upon the ring Il, which in the form shown is a standard common eccentric supporting ring. The ring Il may have a vertically extending ange I8.' This flange I8 may serve to' limit the'movement ofthe reector I5 on-the ring I6 and cause the opening in the reiiector-.to register in a general way with the opening in the ring H. The ring I'i-is usually provided (with an extension I9 having holes 2'0 wherebyvthe ring is adapted to be fastened toa ceiling 2l by screws 22.

It will bereadily understood from the foregoing that according to the practice now in use the lamps and reilectors just described are `located 'in a space between the ceiling and the flooring above. When a Aworkman wishes to do some work on the lamphe may reach in through the opening in the ring Il and lift the reflector ofi the ange I8and move it aside and then he may remove, if desired, the ring I'I. When he is ,nished he may replace the ring I'I first'and then reach in through thev opening I6, grasp the bulb, for example, and set the reflector down on the ringll within the flange I8.

Because, as a general rule the reflectors are .not made to fit the rings or other supporting ineens, or for other reasons, there is invariably a gap 23 of some kind which may besmaller or larger thanthe gap shown, or there may be more than onegap. As a rule, under the'pracvtice at the present time, there is nothing to prevent the dust from the upper surface of the ceiling, which dust settles quite thickly, from coming through-the gap and into, for example, the

-show window Yspace below the ceiling. If, for

' preciate the problem they present.

To remedy this matter I have provided means vwhich in the preferred form takes the form of a ring 24 made of asbestos strands 25 which are kgrouped by means of twisted wire or wires 26 of straight lengths bent to form a relatively at structure or frame with a succession of crosswise, lateral or vertical loops in which the strands are held in transverse bunches or groups in flat matted form with the ends of the strands extending on opposite sides of the wire or loops or other equivalent means and then bent or coiled to form the ring such as shown in Figs. 1, 3, 4 and 5. The wire or wires may be formed at their terminal portions with an eyelet 21 and a hook 28 for securing' the ends detachably together. tecting means the dust guard may be secured about the reflector I and allowed to drop down to the position shown in Fig. 1 where the strands of asbestos on opposite sides of the wire may conform to the reflector and upper surface of the ceiling to form legs 29 which may be roughly at right angles to each other in the form shown with the central or wire portion of the ring loclated nearest the gap.

Experience has shown that with an arrangement like this, the display room is effectively sealed off from dust through any gap of any kind. It will be understood that in the installation of the form of dust guard that I have shown, the dust guard may be inserted above the ceiling and around the reflector and hooked at its ends to form a dust guard conforming to the shape of reflector used.

It will be understood that the dust guard may be made of any length, as desired, and its use is not confined to any particular shape or type of reflector. For example, in the case of lineal reectors, or shades, which may extend in a line around the edges of a ceiling, for example, the asbestos guard may be arranged similarly in reference to said lineal installation of reflectors. It will also be understood that the invention is not limited to asbestos, but other matted or fibrous or other dust impervious equivalent materials may be used.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

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

1. In dust protection means for spaces or gaps between a reflector and a ring upon which said reflector is adapted to be supported, for preventing dust from passing through the space between said reiiector and said ring, including a conforming asbestos guard formed of groups of strands of asbestos secured crosswise by a wire twisted to form loops in which said groups of strands are held, said wire having hook and eye means for securing the terminals of the guard together, said guard being adapted to surround the reflector adjacent its bottom edge, and form legs, one of which is adapted to lie against the reflector and the other across the space.
