SHIELD FOR RADIATORS.

SPECIFICATION forming part of Letters Patent No. 481,900, dated August 30, 1892.

Application filed March l, 1892. Serial No. 423,394. (No model.)

.To all whom it may concern:

Be it known that I, GEORGE E. DIXON, a citizen of Great Britain, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Shields for Radiators, of which the following is a specification.

In the vicinity of a heated radiator there is, of course, a continual upward current of air, and small particles of dust and dirt carried up by this current strike the wall y over the radiator and soil it. In order to prevent this a shield is placed over the top of the radiator, extendingr upward from a point behind the radiator and thence outward over the top thereof, so as to catch the ascending current of air and direct it out into the room away from the wall. Letters Patent No. 435,290, which were granted to Ine August 26, 1890, show such a shield.

The present invention relates to shields of this character; and it consists in certain features of novelty that are particularly pointed out in the claims hereinafter.

In the accompanying drawings, which are made a part of this specification, Figure l is a front elevation of one of the improved shields and a radiator to which it is applied. Fig. 2 is au end elevation thereof. Fig. 3 is a vertical section thereof on the line 3 3 of Fig. l, the parts being shown on a larger scale and the lower part of the radiator being omitted. Fig. 4 is a section similar to Fig. 3, showinga slight modification in the support. Fig. 5 is a section on the line 5 5, Fig. l, on a larger scale. Fig. 6 is a fragment showing a detail of construction. Fig. 7 is a section on the line 7 7, Figs. 3 and 4. Fig. 8 is a fragment. of the upper part of a hot-water radiator.

In Fig. 5 is seen most clearly one of the two end castings A, which are preferably of substantially the shape shown-that is to say, the ends of each casting occupy positions that form about a right angle, while the intermediate portion is curved. Upon the inner side of each is a narrow marginal flange B, which terminates at each end in an open loop or C- shaped portion l.

D is the sheet-metal shield proper, which is bent to a cross-sectional shape corresponding to the course of the flanges B b, so that when the castings A are placed on the ends of the shield the latter will follow and fit against the under sides of said flanges, to which it is secured by bolts or rivets. The flanges being themselves too narrow to accommodate the fastening devices are provided at intervals with perforated lugs b. By bending the sheet metal to this shape tubes d are formed, which strengthen the shield and give it a finished and substantial appearance.

In the shield shown in my former patent the ends of the shield proper are secured to brackets and these are supported by projections from the ends of the radiator. In order to obtain an ornate effect when end brackets are used, said brackets must be of ornamental design and nicely finished. This construction is sometimes preferred, but it is expensive, and one object of the present invention is to conceal the supporting-brackets as much as possible, so that they will not require such a high degree of finish. It is not my intention to abandon any of the features of my former patent; but, on the contrary,I propose to continue to make shields of the form therein shown, as they will be preferred by some because of their highly-ornamental appearance. y The radiators on which theixnproved shield is intended to be used are made up ofanumber of loops or sections F, secured together-at top by a tie-rod G and held at the proper distance apart by struts H, usually consisting of lugs cast on each side of each section and so located that when the sections are placed together in proper relation to each other the lug or lugs on each section bears or bear against the lug or lugs of the next section. The present invention is not, however, confined to the manner of forming these struts; nor, indeed, is it confined to struts at all, as the office which they fill may be filled by the tie-rod or a similar part. In some radiators the loops are spaced by a single strut between each loop and the next adjacent one, as shown by Fig. 4, and in others by a pair of such struts, as shown in Fig. 3.

According to the present invention the shield D is secured to two or more brackets I, each having lugs or projections J, forminga notch j, which is to receive the strut or one of the IOO struts Il or the tie-rod G or other equivalent supporting device located between twoof the loops of the radiator. When this supporting device is non-circular and ts the notch tolerably tight, as shown by Fig. 4, it will not only support the shield but will also prevent it from tilting forward or backward; but where the supporting device is not of this nature other means for preventing the shield from tilting must be employed. rlfhis maybe accomplished in any one of a number vof Ways, some of which are as follows: If there are two struts, as in Fig. 3, the `-notch j may receive the front one and the lower arm or side of the bracket may be allowed to rest upon the rear one or possibly upon the tie-rod; or the notch may receive the" tie-rod and the bracketv may restupon the strut `or one of them; or the notch may receive the strut or one of them or the tie-rod, and a cross-arm K of the bracket may bear against the back part of one or two loops of the radiator.A c

As the brackets l should comebetween the loopsA without much lateral pressure against eitherofthem, and as radiators made `up of a number of loops vary slightly as c to the distance between the spaces, thebrackets are secured tel the shield so as tobe adjustable longitudinally thereon. I prefer to accomplish this by securing the brackets to the shield by bolts and nuts L, and to elongate theopen.- ings 7l in the brackets through which said bolts pass, leaving them open,as shown by Fig, 6, or closed, as shown by Fig. 7." c

ln order to prevent the shield from being accidentally displaced, the lugs J are perforatednear their ends and a pin P is passed through them. u c f Another feature of `the present invention, which I prefer to use inconnection witha shield, but which may be used alone, Vis a curtain N, depending. from apole HO, supported in front of the radiator. Preferably thecurtain is secured to rings that are strung on the pole, so that it may be drawn aside, either partly, as shown by Fig. l, or completely. One object of this curtain is to conceal the radiator, which is sometimes unsightly and never as ornate as a pretty curtain, and another of its objects is to act as a screen'toprevent the heat from being thrown out into the room. Preferably the pole is supported by having its ends suitablysecu'red, to the end castings A, say, by being let into sockets or perforations.

In hot-water radiators the loops are formed with abutting nipples Q, which perform the function of the struts H, and at the same time conceal the short sections of pipe that connect the upper portions of the loops internally.

What l claim as new, and desire to secure by Letters Patent, is

l. The combination, with a radiator having a number of loops, of a shieldhaving brackets extending down between said loops and means between said lo'ops for supporting said brackets, substantially as set forth.

j 2. The combination, with a radiator having a number of loops and `struts between said loops for maintainingthem at proper distances apart, of a shield having"A brackets extending down between the loops of the radiator and engaging said struts, substantially as set forth. f.

3. The combination, with a radiator having a number of loops, of a Vshield having brack. etsextending down between said loops and means between said loops for engaging said brackets,1 said brackets being adjustable longitudinally with .respect to the shield, substantially as set forth.. j

4c. In a shield for radiators,the combination of the shield proper D and the brackets l, secured `to said shield and having the crossarms K, substantially as set forth.

5. A shield for radiators, having the shield proper D bent at its edge into a tube chin combination `with the castingsA, having the iianges B, terminating in the Cvshaped portions b and secured to the ends of said shield, and means for supporting it, substantially as set forth.

6. The combination of the shield proper D, the end castings A, secured to the ends ot' said shield, the pole N, supported at its ends by said end castings, and the curtain O, depending froxn said pole, substantially as set forth. a
