VENTILATOR.

Application filed April 25, 192s. serial No. 634,517.

To all whom it may concern:

Be it known that I, THOMAS A. JENKINS, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Ventila-4 tors, of which. the following is a specification.

This invention relates to a ventilator, de-

signed primarily for use in connection with the Ventilating of buildings, railway cars, street cars and automobiles, but it is to be understood that a ventilator in accordance with this invention, can be employed for any purposes wherein it is found applicable, and the invention has for its object to provide, in a manner as hereinafter set forth, a ventilator including a series of overlapping transparel'lt, translucent or opaque panels of vitreous material arranged in superposed relation and capableJ of being synchronously adjusted from and to closed position to provide for the desired degree of ventilation.

A further object of the invention is; to provide, in a manner as hereinafter referred to, a veiltilator including means for supporting the panels in a manner where they will be air tight when in closed position.

A further object of the invention is to provide, in' a manner as hereinafter set forth, a ventilator including means Ito constitute a cushioned abutment for thev end panels ofthe series when the panels are shifted to closed position and to further provide a pair of supports for each panel having associated therewithmeans to prevent the chipping of the ends of each panel and also to prevent vibration thereof when set up.' as well as insulating each panel from its pair of supports.

Furtller objects of the invention are to provide a ventilator, in a manner as hereinafter set forth, whichis simple in its construction and arrangement, strong, durable,

' colllpact, having the operating parts thereof readilypaccessible forfcleaning or other purposes. thoroughly efficient in its use, conveniently operated, quickly installed and comparatively `inexpensive' to' manufacture.

Vith the foregoing and other objects in view, the invention consists of the novel constructioll, combination andarran ement of parts as hereinafter more speci cally described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood l that changes, variationsl and modifications can be resorted to which come within the scope of the claims hereunto appended.

Referring to the drawings in detail, the Ventilator comprises a body portion in the formbf a rectangular frame consisting of a pair of side bars l, 2, and a pair of end bars 3, 4, the latter being of greater width than the former.

Positioned within the body portion of thel ventilator, as well as projecting forwardly flat rear bar 7, a flat front bar 8 a flat inner bar 9, which is interposed between the bars- 7 and 8, as well as being flush therewith, and eacll of said side members further includes a flat outer bar 10, of less width than the bar 9 and whichis positioned against the inner face of the bar 8, and has its outer face Hush with the outer side edge of the bar 8. Each of said' side members further includes a relatively thin closure strip 11, which is positioned between the bars 7 and 8 and spaced from the bar 10. Interposed between the bar 10 and the strip 11, is a filler strip 12, which abuts against the bar 8 and is of the same width as the bar 10. l

Arranged between the'bars 7, 8, 9 and closure strip11, is a series of combined supporting and bracing brackets which are spaced from each other and each of which comprises a body portion 13, abutting against the closure strip 11, and said body portion 13 has extending from each end thereof an angle-sha ed extension formed of two arms 14, 15. e extensions are oppositely disposed with respect to each other and the arms 14 of. one extension abut 1 against the inner face of the bars 7 and 8.

` the arms 14 of the said extensions by the removable hold-fast devices 16. of thesaid extensions are secured tothe bar 9 b the removable hold-fast devices 17.

VYIhen the side members of the supporting frame are set up with respect to the body portion of the ventilator, the side bars of the body portion extend into the side members of the supportin frame and are clamped between the bars and filler strip 12, in a manner as shown in Figure 9.

The bar 9, in proximity tothe bar 8, is

rovided with a series of superposed open- 1ngs 18, arranged equi-distant from each other, and mounted in each of said openings is a bearing sleeve 19.

The top member of the supporting frame comprises a rear bar 20, a front bar 21, a

bottom bar 22 positioned between the bars' 20 and 21, as well as being flush therewith, a top bar 23, which is arranged against the inner face of the bar 21 and is of less width than the bar `22, an intermediate bracket 24 mounted on the bar 22 and of lesswidth than the bars 20 and 21,/a vclosure strip 25,

ositioned pn the bracketv24 and interposed etween the bars 2O and 21 and spaced from the bar 23, a liller strip 26. interposed between the bar 23 and the closure strip 25 and of the same width as the width of the top bar 23. The bars 20 and 21 abut against the bars 7 and 8 of the side members of the supporting frame, and the bar 22 abuts against the bars 9 of the side members of the supporting frame.

Arranged at each end of the'top member ofthe supporting frame and projecting into' the upper ends ofthe side members of the supporting frame is a combined bracing and' supporting bracket 27 formed with a socket The arms Madone 28a for the reception of the upper end of the bar 9, as clearly shown in Figure 6. The bars and 21 are secured to the brackets 27 by the hold-fast devices 28, and the bars 7 and 8 are secured to the brackets 27 by the hold-fast devices 29. The bar 21 is secured to the bracket 24 by the hold-fast devices 30.

supporting frame is an operating shaft 31,

which is journaled in the portion of greater hei ht of each of the brackets 27 and also in fille upper portion of the bars 9 and which projects from each of the bars' 9 into the side members of the supporting frame. The shaft 31, centrally thereof, is formed with a Worm 32, which meshes with a Worm gear 33, carried by an actuating shaft 34, which is journaled in the bracket 24 and' bar 21 and further projects outwardly from the bar 21 and has its outer portion enlarged or formed with a stop collar 35 to arrest inward movement of said shaft 34 and the outer terminus of the said shaft 34 has a sprocket gear 36 engaged and operated by a pull `member 37 in the form of a sprocket chain.l By this arrangement when the pull member 37 is shifted, the shaft 34 will be actuated, causing thereby the rotation of the shaft 31. 7

The bottom member of the supporting frame comprises a rear bar 40, a bottom bar 41,'a closure' strip 42, a filler strip 43. The bar 39 is interposed between the bars 38 and 40, the closure strip is interposed between the bars 38 and 40, and the bottom bar abuts against the front bar 40 and is of less width than the bar 38, and the said bar has interposed therebetween and the closure strip 42, the filler strip 43. rThe bars 38 and 40 are interposed between the bars 7 and 8 of the supporting frame. Spacing and supporting brackets 44 are interposed between the bars 38 and 40 and are positioned against the closure strip 42, and the bars 38 and 40 are detachably secured to the brackets 44 by the hold-fast devices 45. The bottom bar 4 of the body portion, is clamped betweenv the in Figure 3 of the drawings. f Secured to the outer face of each bar 9, is a lengthwise lextending guide member 46, having one side provided with semi-circular cut away portions 47 and into each of which extends a supporting retainer, tol be hereinafter referred to, for one end of'a ventilator l130 number of ventilator panels.

Secured to the inner face of each of the bars 9, is a retainer element for an actuating rack bar 48, and said element comprises a bar 49 extending lengthwise of the bar 9 and secured therewith by the hold-fast devices 50, and positioned against the bar 49,

as well as extending from each side thereof is a flat strip 51, which is retained in position by thehold-fast devices 50: The rack bar 48 is arranged against one side of the bar 49 and is overlapped by the strip 51 whereby the bar 48 will be slidably connected to the inner side of the bar 9. j

The actuating rack bar 48 extends lengthwise of the supporting frame and each rack bar 48 has it upper end in meshwith a pinion 52,1 carried by an end of the shaft 31 and retained in position by the securing device 53 mounted on the end ofthe shaft 31. By this arrangement, when the shaft 31 is operated, the rack bar 48 will be carried therewith.

The actuating rack bars 48 are each located at opposite sides of each vertical set of pivots, so that' when the pull member 37 is actuated,one of the rack bars moves upwardly while the other simultaneously moves downwardly.

Mounted in each of the bearings 19 is a stub shaft 54, having a reduced end 55 which projects loutwardly from the bar 9.v

The shaft 54-also`projects inwardlyA from the bar 9 and carries asprocket pinion 56, which is permanently in mesh with the teeth of the rack bar 48. The pinion 56 is secured to the shaft 54 by the securing device 57. The foregoing arrangement provides for the operating of the shafts 54 when the rack bar 48 is shifted due to the operation of the shaft 31, and all of the shafts 54'will be synchronously operated asis obvious.

The ventilator includes'a series' of superposed overlappingv synchronously operated ventilator panels and each of Iv vhich is indilcated at 58. Each ventilator panel is rectangular in contour and is preferably formed of vitreous material, although it is to be understood that the panel can be constructed of any desirable material, and also material that is transparent, translucent or opaque., and associated with each end-ofeach panel is `a supporting retainer so set up as to be shifted simultaneously with a shaft 54, underA such conditions providing for the synchronous operation of the panels from and to initially" closed position. Each of the supporting retainers comprises a substantially semi-circular body portion 59. which extends into a cutaway portion 47 ofthe guide member 46. The body portion 59 is provided with an opening 60, in which extends the reduced end 55 of the shaft 54,v

land-said. reduced end 55 is fixedly secured to the body portion 59 so that the latter will be shifted with the shaft 54 when said shaft is operateda through the medium of the 4rack bar 48. The body portion 59 has formed integral therewith a pair of oppositely disposed flat lateral extensions l61, 62, and which are `offset with respect to each other. Formed integral with the body portion 59 is a pair of laterally extending flanges 63, 64, which are spaced from each other, as well as extending in opposite directions with respect to each other. The flange 63 is formed at one side of the body por tionl 59 and the flange 64 is arranged' between the flange 63 and the other side of the body portion 59. The flange 63 is formed integral with-one edge of the extension 61 and further projects outwardly from` the outer end of the extension 61 and carries an abutment member 65 in the form of a screw having threaded engagement with the proljecting end of the flange 63. Carried by theA flange 63, intermediate its ends, is 'a clamping member 66.in the form of a screw having threaded engagement with the flange 63. The flange 63 is disposed at right-angles with respect tothe body portion 59'and the same arrangement is had with respect to the flange 64. Carried by the flange 64 is a clamping member 67, in the fform of a' screw having threaded \engagement with said,v flange 64, and the Ilatter is formed integral with one `,side edge and the outer end edge of the extension 62, whereby the outer end flange 64will be disposed at right angles,

as at 68 with respect to the remaining portion of the flange 64. The opening 60, in the body portion 59' is arranged between Athe flanges 63 and 64, and the inner ends of the flange 63 project beyond the opening 60 and the inner end ofthe flange 64 also projects I beyond the opening'60. Arranged against the flange 63 is a resilient cushioning or protective element 69, and positioned against the inner face of the flange 64 throughout is a cushioning or protective element 70. The element 69 which is `arranged vagainst `the flange 63, is positioned against the inner` facev of the said'langeand extends from the inner end thereof and terminates ata point inwardly with respect'to'the outer endY thereof, or in other words, the cushioningv element 69 has one 'end positioned at th outer end of the extension 61.

The clamping element 66, as well as the clamping element 67 includes a nut 66i for the purpose of retaining said elements in adjusted position.

When a ventilator panel 58 is setup. is positioned between the outer end of -the flange 68 and the abutment member 65, the

latter acts as a' retainer for the panel. The

end of the panel. is positioned between the cushioning elements 69 ad 70,'and the ele ments 66 and 6.7 are adjusted for the purpose of taking up any variations in the thickness jin or'screw may be employed for extending rough the opening 6 0 and engaging lin the shaft 54 for connecting a supporting retainer a to said shaft.

The body portions 59 of the supporting retainers ride in the semi-circular cutaway portions747 ofthe guide member 46, and owing to the setting up of the body portions 59 in the manner as shown and in connection With the employment of the members 46 a practically air tight arrangement is set up.

Depending from the bar 22 is a support 71,. which carries an adjustable abutment 72,

i the latter is formed of cushioning material,

slotted as at 73,and adjustably connected to the support 71, by washers 74 and screws 75. The abutment 72 is employed in connection with the upper ventilator panel 58 of the series of panels, and provides not only a cushion for said panel when the latter is shifted to closed position, but sets up an air tight closure when the panel is in closed position.

Extending upwardly from the bar 39, is a support 7 6, which is offset with respect to the support 71, and which carries a resilient abutment 77 similar in construction to the abutment 72 and connected up in the same manner as the abutment 72, and performs a function similar to the abutment 72 with respect to the lower ventilator panel 58 of the series of panels.

The sprocket pinion can be employed as a knob for actuating the shaft 34, and when so used the pull member 37 is dispensed with, but it has beenfound that the pull member provides for a quicker shifting of the shaft 34 for the purpose of adjusting the ventilator panels.

Although the preferred embodiment of the ventilators is as described and illustrated, yet itis to be understood that changes in the details of construction can be had which will fall within the scope of the invention as claimed.
