5 Claims. (Cl. 126140) While wire mesh of this type is useful for preventing a certain portion of the sparks emitted by the fire from' passingthrough the'screen; that it is not eifective for preventing all the. sparks from passing through the screen and that soot can freely pass therethrough. Screens of this type are further objectionable in that a wire mesh to a great extent obstructs the vision of the fire. The closure device of the present invention contemplates a pair'of panels which are supported relative to a pair of stationary panels located respectively at the top and bottom of the fireplace screen frame to move from a closed position to an open position, in the open position the opening being of a size sufiicient to permit easy access to the fireplace. These movable panels are preferably. constructed of any suitable heat-resistant transparent material such as glass so that a fireplace screen of this type has all the utility of a screen employing wire mesh besides completely insuring against the passing of sparks through the screen and the emission of smoke therethrough. A screen of this type also has the aesthetic consideration that the viewers view of the fire is not hindered or distorted in any manner.

It is, therefore, an object of the present invention to provide a closure device for moving two panels from each other while guiding the movement of the panels.

Another object of the invention is to provide a portable fire place screen having movable transparent panels which do not obstruct the view and which are easily moved apart. V

A still further object of the invention is to provide a portable fireplace screen having movable panels and means for movingthe panels in unison in opposite directions in such a manner that the panels are easily movable from their closed position to their open position relative to the fireplace screen.

These and other objectsof the invention not specifically stated above will become readily apparent from the accompanying description and drawings in which:

Fig;' 8 is a perspective view of the back side of the screen diagrammatically illustrating the panels and linkage mechanism in closed position.

Fig. 9 is a perspective view similar to Fig. 8 showing the panels and linking mechanism in open position.

A fireplace screen embodying the principles of the present invention is illustrated in Fig. 1 and designated broadly by the number 10 and comprises a suitable frame 11 which consists of a pair of upright side members 12 and 13 and a top member 14. Members 12, 13 and 14 are preferably angular shaped in cross section and the vertical side of top member 14 overlaps the front surface of side members 12 and 13 and is secured thereto by rivets 15. Vertically disposed legs 17 of a rigid U-shaped reinforcing member 16, see Fig. 2, are secured by suitable bolts 1-8 to each of the side members 12 and 13 adjacent the lower ends thereof and serve to rigidly tie' the frame members'together at the bottom. V

The screen 10 has a stationary bottom panel 19 and a stationary top panel 20 which are vertically spaced from one another and define the opening of the screen.

The bottom stationary panel extends across the bottom.

of the frame and is composed of a center section21, an upper section 22, and a lower section 23, the upper and lower sections 22 and 23 being in overlapping re-' lationship with respect to center section 21 and center section 21 having its top and bottom edges curled so. as to provide rigidity thereto, see Fig. 7. The opposite ends of center section 21 are secured to the front surface of each of the side members'12 and 13 by bolts 24 and a spacer 25 is positioned between the center section and the front surface of each of the side members so as to prevent bulckling of the front section. The upper. and lower sections are likewise secured at their opposite ends to the front surface of side members 12' and 13 by bolts 26 and 27. A pair, of suitable braces or legs 28 are secured by bolts 24 and 26 so as to support the screen in a substantially vertical position.

The top stationary panel 20 is preferably formed of heat-treated glass and its opposite ends are received in L-shaped'supporting brackets 29, only one of which is visible, which are secured at their ends to the front surface of each of the side members 12 and 13 by bolts 30. It will be appreciated, therefore, that top panel 20 is rigidly supported adjacent the upper end of framell.

An upper movable panel 31 and lower movable panel 32 are likewise supported in frame 11' and are likewise 31 being carried so that in one position its upper edge just overlaps the lower edge of panel 20 and the lower panel 32 being carried so that in one position its upper edge just overlaps the lower edge of panel 31 and its lower edge just overlaps the upper edge of panel 19. In this one position, therefore, it will be apparent that panels 31 and 32 are capable of completely closing the front of the screen opening.

The opposite ends of each of the movable panels 31 and 32 are supported in mounting brackets 33, see Fig. 4, and since each of these mounting brackets is identical in construction, the description of one will apply to all of them. Bracket 33 is preferably in the form of an extrusion of any suitable light metal such aluminum and comprises in the present instancea-channelportiontween sections 35" and the" sections are urged together so as to grip thepaneI-end; To insure against the'panelsliding out of the channel section 34; a'suitable pin37 is received'by sections'35 adjacent the-bottom end thereof,

The neck section 36 has formed therein a pair of guideways 38 which, as will be more fully appreciatedhereinafter, support the bracket forguided up-and-down movement on a guidechannel. 39. Theneck: also has formed thereon a clevis 40 which is fastenedin'any suit;- able manner at its opposite'ends; in an-endlesschain; 41.

It will be appreciated,.therefore,'that mounting bracket: 33 is so designed that brackets of. identical construction can be used for. mountingztheopposite.ends of panels 31 and 32. in spacedapartoverlapping; relationship and the brackets 33 forJsupportingpancl 32 are in end-over-end position withrespect to brackets 33 for supporting panel, 31 so that clevises" are in: opposedi relationship-and the. channel sections, which are; displaced to one side of the centerline, arein spaced-apartrelationship..

As best seen in Figs. 2 and 7, a guide-channel 39:- is. secured adjacent-its upper end by a bolt 42 to side mem: ber 12 and a spacer bar 43,;which also servesto make. the frame more. rigid, and. adjacent its lowerend, by a. bolt 44 which receives thereon. suitable spacers 45, and. bolts 18. A guide, channel; 39 is likewise secured to side-members13 in an identical manner, not visible.

A rigid shaft 46 is,rotata bly carriedlin.suitablefslings 47 which are secured to the upper surface of'top mem-, ber 14 by rivets 48,,only one of. wl1ich-is visible, and the .oppositeends of. shaft46 have suitable gear wheels 49 fixed thereto which are positioned in vertical alignment with the .open top of their respective guide channel 39. A pulley 50 is. rotatably mounted in eachof the guide channels 39' in vertical, alignment with its associated' gear wheel 49 on a bolt 51 which in turn is thread edly receivedina leg. 17 ofmember 16and a washer 52 centers the pulleys for rotation in their respective channels,

Chain41, as previously suggested,.is in' the form of an endless belt which is trained around the pulley and its associatedgear wheel of each of" the guide channels 39, the links of the chain intermeshing with-the teeth ofthe gear wheel49 so. as to cause the shaft torotate when the chain is movedgthereon; Itwillbe'appreciated; therefore, that one flight of eachpf the chains-mvesin one. direction while the other'flight moves inthe opposite direction alike distance. gested the brackets-33 carrying panel 31' are interconnected in one flight of chains 41 whereas brackets 33 carrying panel 32- are interconnected in the other flight of chains 41. A knob 53'is secured to one of 'thebrackets- 33 supporting panel 31'and isuseful in moving-panel 31 and consequently panel-32 from its closed-position to its open position, and each of'the slings 47 threadedly receives a screw 54, which is efiective for moving:

shaft 46 and consequently adjusting the slack in chains:

in-counterbalancing relationship sothat panel 31 is' heldi,

impositionby the weight of panel- 32; This result'is' obtained since bothof-Ithe panels are of about equal. size and weight, and; of; course, some frictionis devel-.. oped inthe; linkageconnecting: theopposite ends;v of

the panels which will prevent movement ifsomeidiffer-v ence in weight of panels is present. Becausexof the counterbalancebetween panels: 31 and 32,. the? panel 31" can be movedupwardly-byknob. 53 adjacent'top: panel 20' with only a. minimum. of exertion; .the, panel.

32"in turn: b'eingconsequently moved downwardly: adia-v cent bottom: pand -19: Amopening in:..ther screen-rise As previously sugthus provided for access to the interior of the fireplace.

Only a minimum of exertion is likewise required tomove panel 31 and consequently panel 32 into their closed and overlapping positions relative to stationary panels 19 and 20 for sealing the opening of the screen.

Because each of the chains 41 are interconnected by shaft 46, the movable panels will move relative to the A guide channels withoutbendingand will remain parallel to each other. For-instance; if'knob'53 is raised, this movement will be transmitted by its adjacentchain 41 to shaft 46 and thento the other. chain 41 so that both chains will be caused to move in unison. Of course, the same action will'result when the' handle 53 is lowered so that the movable panels will always move together in parallel relationship and in opposite directions.

As previously described, the panels 20, 31 and 32 are constructed of heat-treated or tempered glass which does not weaken when" subjected to high temperatureand which will not break easily when struck with a hard object such as fireplace tools. these. panels permits the interior of the fireplace to be observed when the movable panels arein closed posi-- tion and the panels protect against soot, smoke; and' sparks. entering the room from the fireplace. The'bottom panel 19 is preferably formed of metal and the center .section. 21? preferably has openings 55 formed thereinior. permitting; the. circulation of air through the By. the. present invention; a novel fireplace screenisprovided.v which incorporates: novel means; for movably supporting:v the panels. 31 and 32 relative. to: the: screen: frame. It :is understood thatthezprineiples: ofjtheepresent invention. can be utilized. by various. otherv closures. in.
