9 Claims. (01.237-79) This invention is directed to new and useful improvements in wall radiator enclosure of the type that is usually installed in a building during its construction.

This type of enclosure comprises generally a casing surrounding the radiating means open at its bottom and top to permit circulation of air therethrough by convection and a damper means positioned above the radiating means to control the volume of heated air passing through the casing.

In modern `building construction steel window frame and sash is commonly used to increase the reproong of the building and inasmuch as the radiating means is generally positioned adjacent a window the enclosure must be constructed to lit and be secured to such steel construction.

It is the primary object of this invention to provide such a metal radiator enclosure that is simply designed so as to be readily vassembled with and secured to the modern type of metal window sash construction.

A further object is to provide such an enclosure that is easily opened for cleaning purposes without injury to the interior finish of the space in which it is located.

Still another object is to provide a novel locking means for assembling and holding the enclosure in assembled position.

Another object of this invention is to provide such an enclosure that is not secured to or positioned against the radiating means so that the movement of the heat transferring means due to variation in temperature cannot affect the enclosing structure.

Still a further object is to provide an enclosure of the type described having novel reinforcing means, and shaped to facilitate the application of plaster to the adjacent walls, the installation of base boards and the positioning of insulation between the back of the enclosure and the wall of the space in which positioned.

Still another object is to provide a novel enclosure construction in which the back of the structure has supporting means for the front portion of the enclosure whereby the front may be easily and accurately pivoted into closed or assembled position.

Further objects and advantages will be apparent from a study of the following detailed description.

In the'drawings:

Fig. 2 is a vertical cross sectional view taken along line 2-2 of Fig. 1. Y

Fig. 3 is a sectional view taken along line 3-3 of Fig. 2.

Fig. 4 is an enlarged detail view of the securing meansshown in the uppermost part of Fig. 2.

Fig. 5 is a sectional view similar to that of Fig. 2 of a slightly dilerent form of enclosure embodying this invention.

Fig. 6 is a cross-sectional view taken on line E-Sof Fig. 5.

In detail the enclosure comprises a. back plate I, a front assembly 2 and a damper assembly 3. The upper edge of back plate I is bent to horizontal position to form a flange 6 extending from the plate I in a direction away from the wall 5 adjacent which the enclosure is to be positioned. This ange d is provided with downwardly projecting pins 6 which are adapted to t into holes l that are drilled in the underlip 3 of the window sill Q.

The lower edge ofplate I is provided with a lip I0 extending horizontally toward the wall 5 to add to the stiffness of the back plate I. The lower portion of plate I is further strengthened horizontally by means of angle member II welded to the back plate from side to side. The back plate I is reinforced vertically by channel members I2 positioned on the wall side of the plate,

A. back sheet support plate I3 is the means of anchoring the lower part of the plate I. Plate I3 is provided with vertical slots It for receiving lock bolts I5 which extend through; the lower side of plate I are welded thereto and are secured to plate I3 by means of nuts I6. The slots provide adjustment to compensate for the variations resulting from the usual tolerances in measure- Support plate I3 extends downwardly terminating in a lip I'I provided with holes for wood screws I8 which secure the plate to the wood screed `I9.

As best shown in Fig. 3 the vertical edges of plate I are formed at right angles to the back and extend away from wall 5 to form lips 20. These lips are each provided with an inwardly extending pin 2l for purposes hereinafter described. Adjacent the bottom of each of the lips 20 are outwardly extending pins 22.

In order to provide horizontal reinforcing for the top portion of plate I an angle member 23 extends across the plate and is secured thereto by means of bolts 24 welded to plate I and extending through slots 25 in angle 23 and nuts 26. The slots provide for vertical adjustment of angle member 23 which is clamped in position to form a recess or groove 21 between the lower surface of underlip B and the upper surface of angle member 23.

It is clear that the above back construction permits it to be installed as the trim is prepared for plastering, Later the radiating means may be positioned relative thereto and the front of the enclosure assembled on the back as will be hereinafter described. This construction provides a plaster stop so the plaster may be easily brought flush against the sides with the excess iiowing around the edges to present a neat nished appearance.

lf it is desired to position insulation between the back plate and the wall this may be readily done by positioning the insulating material between the channel members I2. However, without insulating material positioned there the air space between the wall and the back plate will provide a certain insulating eiectf' Furthermore a back plate so constructed may be installed as the building is being constructed and will in no way interfere with the subsequent installation of the mop or base board here shown as 28.

The front assembly 2 comprises a front plate 29 the vertical edges of which are formed at right angles relative thereto forming lips 3U which abut the edges of side pieces 3| which are welded thereto, which joint is reinforced by batten strip 32. This combination provides vertical bracing. Horizontal bracing is provided by channel member 33 positioned centrally across iront plate 29. The lower edge of frontplate 29 is strengthened horizontally by being folded back on itself as shown at 34.

The upper portion oi plate 29 is bent backu'ardly at about a 30 angle in which portion is formed a slanting punched grille 35. The upper edge is bent to form a rearwardly extending horizontal lip 36.

The bottom edges of side pieces 3| have slots 31 near the rear edges of the pieces and substantially centered in the lower edges of said pieces 3| are arch-shaped openings 38. A novel, eccentric positioning and locking mechanism is secured to each of the side pieces 3| adjacent the grille 35 and comprises a hook member 39 collared about a cam or disk 40 eccentrically positioned relative to concentric cylindrical projections or pins 4I and 42 and forming a part thereof. The larger projection 4I is provided with an hexagonal recess 43 and is journaled in an opening in side piece 3|. The other projection is journaled in an opening in a stirrup piece 44 shown partially broken away which is secured to the side piece 3|. A pin 45 projects inwardly from the inner surface of each side piece 3| adjacent the hook member 39 to provide a stop for member 39.

The damper assembly 3 comprises a rectangular valve member 46 of substantially the same length and width as the inside of the enclosure, pivotally positioned across the center of the enclosure by means of shafts 41 and 48 which are flattened at their inner ends and secured to the valve member 46 by means of rivets 49. Surrounding shaft 41 between the valve member and side piece 3| is a compression spring 50 which normally forces the valve towards the opposite end of the enclosure. On the outer end of shaft 41 which extends through side piece 3| is secured a handle 5I. Shaft 48 is journaled in a stirrup shaped fastening member 52 which is secured to side piece 3|. This fastening memaeeasai ber is provided with openings 53 adapted to rereive the rounded end portion of finger 54 for holding the valve in various positions.

This enclosure is adapted to enclose any type of heat radiating means which, as illustrated. comprises a hot fluid conducting pipe 55 having heat radiating hns 55. The radiating means has inlet and outlet connections 51 and 58 respectively (the illustration is for use with a downfeed steam line) which extend into the enclosure through arch shaped openings 3B without in any way being secured to or resting upon any part of the enclosure assembly.

The above described form of radiator enclosure is assembled as is now described.

As soon as the steel window sash is installed in the building this can be done. The appropriate holes 1 must be drilled in the underlip 8 and then the back plate I may be hung thereon with pins 6 positioned in holes 1. The back sheet support plate I3 is then adjusted on bolts I5 and secured at proper position to bring lip I1 flush with upper surface of wood screed I9 to which it is then secured by means of screws I8. Angle 23 is secured to plate I by means of bolts 24 after being properly adjusted so as to provide a recess or seat 21 of correct size for receiving lip 35. At this point the plastering may be done and thereafter the radiating means may be installed in proper relation to the back plate.

To complete the enclosure the front assembly 2 is then positioned relative to the back with side pieces 3| outside of lips 20 and slots 31 engaging pins 22. The front assembly is then pivoted on pins 22 toward the wall 5 until lip 35 is positioned in recess 21 and against back I, as clearly shown in Fig. 4. Thus the pins 22 provide support and guide means.

At this point the locking means is brought into operation. An hexagonal tool is positioned in hexagonal recess 43 and turned. 'Ihe turning of the eccentric or cam will cause the outer end of the hook member 39 to first be lifted, then be moved toward the wall, then lowered to engage pin 2I and then tend to move away from the wall to draw the front assembly firmly against the back plate. A spring washer 59, or any other suitable means may be used for causing sufficient friction to hold the hook in any desired position. Pin 45 is so positioned to prevent hook member 39 from falling below operating position for pin 2|.

The valve 4E of the damper assembly is operated by means of handle 5I. In order to position it any desired position the handle is rotated as desired to cause the round ended finger 54 to be disengaged from any of the holes 53 by moving against spring 5B. Handle 5| is released at the desired position and the spring 50 will hold it there. 'Ihe channel member 33 provides a stop for the valve in closed position and a damper stop for open position is provided by angie member 60.

To open the enclosure for cleaning it is only necessary to reverse the operation of the locking mechanism which action will move hook members out of engagement with pins 2l and will permit the front assembly to be pivoted away from back plate I and then lifted from pins 22.

Another embodiment of this invention is shown in Figs. 5 and 6, in which the general construction, the damper assembly, the locking means are much the same as above described. Parts which are of the same construction as such a case the back plate 63 must be formed with an upper edge bent downwardly at substantially the same angle as the upturned lip B2, to form a downturned lip 84. A reinforcing angle member 65 provided with vertical slots 66 and of the same contour as the upper edge of plate 63 is clamped to plate 63 by means of bolts 61 to firmly clamp the back to the window sash. A right angle reinforcing member 68 likewise provided with vertical slots 69 to permit adjustment, is also securedv to back plate 63 by the same bolts 61 with its horizontal portion i0 spaced below the lower surface of the horizontal portion of underlip 6l to provide a recess orY groove for horizontal lip 36 of the front assembly.

The lower portion of the back plate 63 is formed to provide a parallel but inwardly spaced fastening edge ll for securing the plate directly to the wall by means of screws 12. Horizontal reinforcing for the bottom of the back plate is provided by a channel member 13 which also acts as a stop for the construction of the cement or plaster baseboard 73a and vertical reinforcement is provided by channel members 1d.

The damper assembly is fundamentally the same as hereinabove discussed the only difference being in the stop means in which a plurality of depressions l5 are used in place of holes 53. It is clear that any stop means may be used such as for example a resiliently held ball carried by the movable valve to cooperate with the depressions.

Likewise the eccentric locking mechanism may be constructed to be operable by any well known means such for example by replacing the hexagonal recess with a slot so that it may be operated by a screw driver.

In order to present a neater appearance it may be desirable to indent a part of the side of the enclosure at the operating end of the damper assembly so that the operating handle may be ush with the side or a knob may be substituted for the handle. All of such details are well known in the art and form no part of this invention.

The advantage of providing a slanting grille 35 is that no object can be placed thereon to interfere with proper heat circulation.

The back construction shown in Fig. 5 is particularly adapted for buildings in which cement or plaster baseboards are to be used for the channel member 13 provides a stop which enables the workman to rapidly and neatly construct such a baseboard.
