June 4, 1940. M. SINCLAIR REGISTER SHIELD AND FILTER Filed May 12. 1959 2 Sheets-Sheet 1 Attorneys June 4, 1940. M. SINCLAIR REGISTER SHIELD AND FILTER Filed May 12, 1939 2 Sheets-Sheet 2 A tzomeys Patented June 4, 1940 UNITED STATES PATENT OFFICE 4 Claims.
The present invention relates to registers such as wall registers for hot air heating systems, air conditioning systems and the like, and has for its primary object to provide a combined shield and filter adapted for detachable engagement over the discharge opening of the register to provide a screen for cleaning the heated air before'it enters the heated space and a construction to deflect heated air downwardly into the heated space upon obstructions forming in the'screen.
A further object is to provide an adjustable frame for the shield for fitting upon registers of various sizes within a limited range, and also to provide a slidably adjustable screen mounted in the frame.
A still further object is to provide an attachment of this character of simple and practical construction, which is neat and attractive in appearance, which may be easily and quickly installed in position on the register and which at the same time is relatively inexpensive to manufacture and otherwise well adapted for the purposes for' which the same is intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which- Figure l is a front elevational view.
Figure 2 is a vertical sectional view taken substantially on a line 2-2 of Figure 1.
Figure 3 is a fragmentary sectional view taken substantially on a line 3-3 of Figure 1.
Figure 4 is a fragmentary rear elevational View of one of the upper corners of the frame.
Figure 5 is a fragmentary perspective view of the end of the upper frame member, and
Figure 6 is a similar view of a modified frame construction.
Referring now to the drawings in detail, the numeral 5 designates a metallic screen frame generally which includes an upper frame member 6 of channel-shaped formation in cross section and a side frame member I likewise of channel form and of an increased width toward its lower end as more clearly shown in Figure 2 of the drawings. A pair of the frame members 5 are provided with the upper frame members 6 of each pair having telescopic engagement to horizontally adjust the frame members relative to each other for fitting about the opening of a wall register 8 of conventional construction and which usually includes the hingedly mounted control door 9. The telescopically engaging frame members 5 form a U-shaped frame for the lower ends of the side frame member I are free. I
The upper frame member 6 of each frame memher 5 includes legs 30 and 3| relatively widely spaced, as is clear from Figure 2, the latter leg being disposed adjacent, and the former leg being spaced from, a register when the device is associated with a register. The side frame memher 1 of each frame member 5 includes legs 32 and 33 in the relationship of the legs 30 and 3|, as is clear from Figure 3.
In the frame construction as illustrated in Figure 5 of the drawings, the inner face of the upper frame member 6, as well as the vertical side frame member I, is formed with a channel In within which is fitted a rubber or similar resilient packing II adapted to contact the outer surface of the register 8 to seal the upper and side edges of theframe. The outer edge of the upper and side frame members are also formed with, a marginal bead l2 whereby the outer flange l3 of the frame members is offset inwardly to provide a recess within which is seated the sectional screen indicated generally at M.
The screen is formed of a pair of sliding screen sections I5 and I6, each of said sections having inwardly bent tongues l1 and I8, respectively, formed at the upper and lower edges thereof and adapted to accommodate the other of the sections to provide a track for slidably connecting the screen sections for horizontal sliding adjustment.
The lower edge of the side frame members likewise are provided with upwardly bent tongues l9 which support the lower corners of the screen sections I5 and Hi. If desired, the upper corners of the screen sections may be secured to the frame 5 by means of screws or the like 20.
Each of the screen sections l5 and it include a frame 2| of channel form within which the edge portion of a relatively fine mesh screen 22 is inserted and clamped in position between the side walls of the channel the screen constituting a filter. The frame 5 is secured in position to the register 8 by means of a threaded bolt 23 which is inserted through the side frame member 1, at an intermediate point, the inner end of the bolt having threaded engagement with an eye 24 formed on the outer end of a hook member 25 which has its inner end bent angularly in the form of a hook 26 and engaged under the edge portion of the register 8 as clearly shown in Figure 3 of the drawings.
In Figure 6 a modified construction of the upper frame member designated at 21 in this instance, is shown, the frame member being of channel form and having beads 28 and 29 formed on the inner ad outer marginal edges of the frame, the bead 28 being adapted to abut the register 8 While the bead 29 provides the abutment for the upper and side edges of the screen member.
The lower ends of the side members 1 are free and the increased width thereof serves to incline the front face of the frame outwardly and downwardly. The lower open side of the frame permits any air deflected by the screen to pass into the heated space from the register. The opening at the bottom also permits the operation of the door 9.
It is believed the details of construction and manner of use of the device will be readily understood from the foregoing without further detailed explanation.
Having described the invention, what I claim is- 1. A register shield comprising a pair of extensi'ole frame members including top frame members and side frame members, said frame members being of channel form in cross section and the channel of said side frame members being of increased width toward their lower ends, to incline the front edge of the frame upwardly and inwardly, the bottom of said frame members being open to admit air upwardly behind the memhere, an extensible screen mounted in the front edge of the frame, a plurality of hooks engaged with the register and bolts inserted into the frame members and having threaded engagement with the hooks to detachably seem-e the frame members in position.
2. A register shield comprising a pair of extensible frame members including top frame members and side frame members, said frame members being of channel form in cross section and the channel of said side frame members being of increased width toward their lower ends, to incline the front edge of the frame upwardly and inwardly, the bottom of said frame members being open to admit air upwardly behind the members, said frame members further having a marginal bead, an extensible screen mounted against the frame members inwardly of the bead and means for detachably securing the frame members to the register., I 3. A register shield comprising a pair of extensible frame members including top frame mem bers and side frame members, said frame members being of channel form in cross section and the channel of said side frame members being of increased width toward their lower ends, to in- 4. A register shield comprising a pair offrame members operatively connected for extension adjustment, each member including a top frame member of channel cross-section and a side frame member of channel cross-section, said operatively connected members forming a U-shaped frame having a free open side, said channel-shaped top and side members being relatively wide to space .i
the legs of the channels apart, the legs forming one side of the channels being disposed adjacent the associated register andthe legs forming the other sides of the channels being spaced from the associated register when the shield is secured.
thereto, an extensible screen connected to said register-remote channel legs in a manner to adapt itself to the adjustments of the frame members and to space said screen from the as; sociated register, said open side of said frame permitting any air deflected by the screen to' pass into the heated space from the register, and
means for detachably securing said frame and screen assemblage to a register. v v, c
