ROLLYN HAWKINS, OF INDIANAPOLIS, INDIANA.

DUST DFLECTOR AND CATCHER FOR RADIATORS.

Specification of Letters Patent.

Patented April 17, 1906.-

Application filed February '7. 1905. Serial No. 244,610.

To all whom it mag/concern:

Be it known that I, ROLLYN HAWKINs, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Dust Deflectors and Catchers for Radiators, oi' which the following is a specification.

This invention relates to improvements in d ust-catchers for radiators.

The dust and disease germs which are carried on peoples shoes from our streets and are left on the carpets and oors in all residences and public buildings are kept in circulation in the air currents that pass up through radiators in buildings heated by steam or hot water. All radiators when heated draw the dust -laden air from the floors up between the sections, thence to the top of the radiator, from whence it is diffused against the wall directly above the back oi the radiator and upward to the ceilinor and outward into the room. The ilth ilack dust is thereby deposited on the wa ls, oeilings, draperies, furniture- --in fact, on all objects in the room, and even upon the food when that is left uncovered. This dust is not only very injurious to the wall-decorations and draperies, but is often heavily laden with germs that spread disease. It is generally found necessary to annually redecorate the walls and ceilings in steam and hot-water heated residences, flats, and other buildings. Numerous radiator' shields and deilectors have been invente and tried and have uniforml failed for the reason that dust when thus shielded or deflected into the room is simply kept in circulation and will eventually settle on the draperies and decorations.

The ob'ect of this invention is to separate the dust iirom the air and retain it in a suitable holder, from which it can be easily removed with a damp cloth without the inconvenience of removing the dust-catcher from the radiator.

The object also is to provide a means whereby the dust-catcher can be readily removed from the radiator by simply lifting it therefrom when it is desired to do so for any purpose.

The object also is to'provide means whereby the dust-catcher canbe tted to all sizes and styles of radiators. y

A further object of the invention is to provide an adjustable apron at the rear of the `dust-catcher which can be set with its lower edge against the wall, where the radiators are set farther than six inches away from the wall, it not being necessary to adjust the apron when the lower edge of the latter is under six inches from the wall.

The object of the invention also is to rovVide a wa l-protector to be placed back o the radiator where the walls are uneven by reason of panels, casings, and the like, which keep the lower edge of the apron from fitting close thereto.

I accomplish the objects of the invention by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a detail in perspective ofthe upper end of the radiator, showing my dustcatcher attached in o erative position. Fig. 2 is a vertical section o same. Fig. 3 is a detail in side elevation of that part of the removable ,fastening device which is iixed to the apron.

Fig. 4 is a detail in front view of the entire mechanism used for removably securing the dust-catcher to the radiator, the view showing said parts detached from the dust-catcher and from the radiator and also showing thel same without the front clamp and connectingrod. Fig. 5 is a view in vertical section of a radiator equip ed with my dust -catchen apron, and wal -protector. Fig. 6 is a detail in horizontal section on the lines 6 6 of Fig. 5. Fig. 7 is a detail in side view ofthe lower end of one of the end plates of the dustcatcher; and Fig. 8 is a detail' in vertical section of the wall-protector, showing the means by which its upper end is secured.

Like characters of reference indicate like parts throughout the several views of the drawings.

9 represents the coils of a radiator for steam or hot water, of usual construction', and 10 is a holding -plate, preferably half-round in cross-section, to fit between adjacent pairs of radiator-coils and contact with the adjacent members of the pair, between which it is placed. 11 is a bolt which is passed horizontally between said pair of coils, first three h a clamping-plate 12, placed ,at the front of the radiator between said same pair of coils, and

then through the plate 10 in the manner shown in Fig. 2, and then said bolt is held by screwing the nut 13 upon its threaded end. The holding-plate 1() will preferably have a vertical ,series of bolt-holes in order that the bolt 11 may be placed higher or lower in the radiator to avoid the connecting members of the radi- IOC IIC

ator lpairs or other obstructions that are common y found and which vary in positions with the different styles of radiators in common use. The holding-platel will preferably be concave to let the nut in past its edges; The plate 10 will have a top extension, which is bent at right angles to form Kthe horizontal member 14, that will occupy a position upon formed therein.. The grooves are in pairs located opposite each other on the front and back sides, respectively, as shown at 16 in the drawings. l

17 is the hood: of my dust-catcher, which may be made out of sheet steel, copper, brass, or other suitable material, plain or crimped, the crim ed material being preferable for the reason t at it will hold its shape better, and any buckling of the metal will not be as noticeable as with plain sheet metal.

1'8 represents the hood ends, which are made out of cast metal and are stiff and rigid in construction to ive shape and rigidity to the hood which is astened to these ends.

19 is a slotted holder which is fastened, preferably by rivets, to the under side of hood 17.

'This holder has a downwardly-projected member'provided with the under end slot 20. The slot 20 will preferably have inwardlyslopingsides and will be wide enough to receive said flange, and in operative position the inner end of the slot w1ll bear upon the to of the flange, thereby forming the principa sup ortfor' the hood 17 Arocking movement o the hood is prevented by the widening of the edges of the slot into flan es, as shown in Figs. 3 and 4, which give a su cient bearing a ainst the grooves 16 to hold the hoodri id yinposition. Lon itudinalmovement o the hoo'd isv revente by the formation of lugs 21, whicli are extended inwardly from the sides ofthe slot 20. These lugs entcr the grooves 16 in the flange of the head 15. The length of the flange is such as to receive a plurality of grooves in order that the holder may be made to fit at any part of the length of the flange without any special adjustment of the distances apart of the heads 15 at each end of the radiator. This is important 'because the thickness of the coils may vary considerably in different makes ofl radiators, which would make it extremely difficult to place the heads e .ually distant from each other in all cases. AJugs 21 are preferable to flanges for the reason that the lugs will adjust themselves without binding in the grooves under conditions that would cause a flange to bind. While I have shown two lugs justable extending in from each side ofthe slot, I'have found that only one is necessary, and in practice only use a single lug.

The front of the hood 17 is bent downwardly into the half-cylindrical roll 22. lt is then bent upwardly adjacent to the edge to form the member 23, and the edge of that member is bent toward the front to form the horizontal ortion 24. This forms a ocket, as clearly siiown in Fig. 2,- into whichl t e dust and dirt are guided by the under side of the hood, and theescape'ofthe collected matter is prevented by the said horizontal member 24. Thisconstruction ff rms a very important feature of my inverion. The back edge of the hood is bent d: Iw .i to form the approximately vertical member 26, and the edge of that member is bent to the rear to form the member 27 to make a close fit against the wall when the radiator lstands uite close thereto; but when the radiator is ocated re' mote from the wall, as shown in Fig. 2,. an apron 29, which is adjustablein its position, as shown in dotted lines inFig. 2, is required to direct the current ofair rising between the radiator and wall into the dust-catcher. This `apron is formed out of sheet metal, with a top roll or bead toreceive lugs 30 from the plates 18 of the hood, thereby forming a inge connection which makes the apron `ad- Thevplates 18 are provided with openings to receive the'bolts 31, by which plates 34 at the ends of the apron are pivotally connected, and the plates 18 have the slots 32 concentric with the holes for the bolts 31.

the plates 34 have overlapping extensions 35, through which the bolts 31 are passed. The extension 35 has the bolt 38, which passes through the slot 32 in the plate 18. and by means of a nut on the threaded end of said bolt the plate may be tightened so as to lock plates 34 in any' adjustment that may be given. These'plates have pairs of inwardlyprojected lugs 33 to receive the ends of the The ends of the plates 34 are made con- -cave to fit the rounded ends of plates 18, and

apron and raise and lower the apron by the raising and lowering of the plates. Thus when the radiator is awayfrom the wall so far that the dust-hood does not prevent airn currents from rising .between the radiator and wall the apron 29 b the means above described can be set to c ose the distance in the `manner as shown in Fig. 2.. The apron 1s hinged as close to the hood as possible, so as to make the joint tight between them and is thereforeeccentric of the pivotal attachment of' the plates 34. The apron is loosely held between the lugs, so as to slidefreely between them in adjusting the apron.

In Fig. 5, 40 represents a molding which extends out from thel wall, so as to interfere wl'th the proper adjustment of the apron. Wmdow-casings, pipes, and other obstructions frequently occur which makes it nerr-ssary in order to adapt my device to all localities to provide a false wall between the real wall and the radiator, which will be connected up with my dust-catcher, so as to direct the heated currents in front of it into the dust-catcher and prevent the heating of the air between the false wall and wall proper. This false wall, as shown lin Figs. 5 and 6, comprises a vertical sheet-metal plate 41, thev lower end of which rests upon the floor and the upper end of which extends up into the range of adjustment of the apron 29. It also comprises a sheet of corrugated metal 43, which is laced between the late 40 and radiator an is separated there om by the horizontal metal bars 44, the bars 44 and the two metal plates being riveted together, as shown in Fig. 6.- The corrugated metal^43 terminates at a suitable distance above the floor, as shown in Fig. 5, to allow the free entrance of air-currents into the open ends of the ilues formed by the corrugations, and the circulation or flow of air from the rear to the front of plate 41 is permitted by a formation of holes 46 through plate 41 adjacent to the lower end of the corrugated metal sheet43.

The upper end of the above-described false wall is held in position against the radiator bymeans lof the metal straps 48, which are fastened by means of the bolt 11 to the radiator and which extend from thence to the top of the false wall and are bent across and down at the back of the wall in the manner as cleaily shown in Fig. 8.
