ySpecification of Letters Patent.
Application led September 30, 1912. -Serial'Na 723,055.
To all whom it may concern Be it known that I, FREDERIC PARKER, o Bedford. in the county oli' Middlesex and State olf Massachusetts, a citizen of the United States, have invented a new and useful Improvement in VVindow-Shields, of
which the following. is a specification.
'fi/he nuisance :from the noise ofA traflic to he occupants of a business building located on /a busy street is too well known to require amplification. My invention is intended to reduce the amount of noise which penetrates the building especially when the windows are open, and it4 consists in a shield arranged to reflect the solrnd waves so that y to a large extent they are diverted preferably upward and fail to reach the roomlso shielded.
That waves of sound, like waves of light, are capable of reflection 1s well known, and.
by making a. reflector of transparent mate- .rial a large proportion ofvsound clan'be reflected while the light will 'pass through the reflector, and by providing suitable openings for ventilation the comfort of the occu-` pant of the room can be secured with scarcely perceptible losslof either light 'or air..A
I have shown inl the drawings two forms of my invention 'one of which is substan tially permanent in the sense that when once in place it isintended to remain attached to .l the building'until removedbod'ily, for example, during-the winter season, and the' lbed as to receive the sound waves coming therefrom and reflect them Vinsuch a direction as eventually to dissipate them so far as the room controlled by the window is concerned.
It is of course well known that sound waves will penetrate all materials to acertain extent, but the impact of sound waves 'i passing through the air against a solid material results in a large percentage of reflection coupled with a certain amhunt of refraction and a very small percentage of penetration, so that in the operation of my inrentlon while the result cannot be' the absolute exclusion of sound, such a percentage Patented Aug. 25, 1914. A
will befexcluded as to render an otherwise l noisy room comparatively quiet.
In the drawings two forms of my invention are shown. y
Figure 1 lis a vertical section of a form of my vinvention arranged for permanent use outside a window, Fig. '2 being a section on line 2 2 of Fig. l showing thedevice inplan. Fig. 3 isy an interior elevation of another form of my invention, Fig. 4 being a section on line 4 4 of Fig. 3. Fig. 5 is anenlarged sectional detail of the reflector shown in Fig. 8, and Fig. 6 a corresponding section showing a different form of reflector.
AJ is the window frame in which are hung the upper and lower sashes B, B1, all of any ordinary construction.
Referring to Figs. l and 9., the reflector as here shown comprises a sashlike frame C in which are set two plates of glass c, c1 or other material in such manner as to be separated from each .other leaving an air chamber between. A single plate or pane will answer in many cases, but to reduce the percentage of penetration two or more panes are preferable lbecause the intervening air chamber servesl to changethe speedo the L sound waves and reduce the1r capacity for penetrating the sec-ondzplate. Glass is of course* preferable to an opaque material as itwlll not materially darken the room. The
reflector is usually se't at an angle say olf 30 to the building so that sound ,waves coming upA from below will strike the reflector and to a large extent glance oil' and upward and so while some of them may penetrate to a certain extent, a large percentage of their energy will be dissipated upward'. It may ble otherwise set, however, according to the requirements of anyvespecial situation, for example, the height of the window from the ground or the width of the street, or both. Lpiefer that the reflector may extend upward to about half the height of the open window as'shown or higher if thought best according tothe location of the window. and to prevent leakage around the top of the reflector lfprefer to provide a vertical extension C1 of the reflector as shown. D, D
are side walls of glass, wood or other suit' able material to prevent lateral leakage of sound into the window. these walls extending under the upper sash if thought best.
The whole thus forms a shield which to av large extent reduces the noise atqthe window. `The frame C may be attached to the window frame at the bottom by angle irons (I and should be provided with openings Z to allow proper drainage in case of rain. The opening C2 at the top of the shield should be sullicient to allow for proper ventilation of the room when one of the sashes is raised.
In Figs. 3, l and 5 the shield takes the form of ana-dditional sash E which may be. balanced like an ordinary sash or may be held in place and removed like a fly screen. In either case the sash or frame contains a series of reflecting strips e of glass set at anr` angle say of 30o from the vertical with air spaces for ventilation between each pair of. reflecting strips. It is preferably arranged inside the window as shown-so that thesound waves coming up from below will strike the strips e and glance off upward. In setting these strips into the 'fra-me vor sash E they should be placed sufficiently close together to reduce the chance of leakage to the minimum and at the same time provide a substantially continuous rellectii'ig surface. It will be seen that in this case as before, there is air between each pair of strips so that any sound waves penetra-ting vone strip will pass into the a-ir wherein its velocity will be reduced and then a portion of' it will pass into a second strip, etc., this changing of speed assisting in the killing of its energy.
In Fig. G is shown another form in which the reflecting strip may be set into a sash, the reflectors being preferably glass as before. In this case strips el, e2 of glass or the like are arranged at an angle so that the approaching sound waves on passing in between strips el, el will strike a strip. e2 and be reflected upward against a strip el, etc., in a way which will be easily understood.
There are other arrangements of reflecting shields which may be adopted to secure the desired result and embody my invention which broadly speaking comprisesthe use of a shield having one or more reflecting surfaces and located with such relation to the window'that a large amount of the sound will be reflected without any materia-1 interference with ventilation. rIhe use of glass in the construction of the `reflectors is desirable because it does not interfere ma? terially with the natural lighting of the room, but when artificial light is used by preference an opaque reflector may be used.
If desired the walls' D, D may be of glass and the shield as a whole may be curved in horizontal section instead of angular as shown in Fig. 2.
It will of course be understood that lunder certain conditions by the use of certain kinds of glass light as well as sound may be re-I flected.'
TWhat I claim as my invention is:
l.V A window shield comprising a sound reflector having a surface adapted to be located at an angle to a window and means for supporting it with relation to a window :frame with its u Jper edge farther from the window than its lower edge lwhereby sound striking it from without will be reliected.
2. A window shield comprising a reflector having a surface adapted te be located at an angle te a window, means for'supporting it with relation to a window frame with its upper edge farther :from said fra-me than its 'lower edge .vhereby sound striking it at an 5 angle from without will be reflected, in combina-tion with walls adapted to form with the window shield a Ventilating duct thereto.
3. In combination with a window, a sound shield comprising a reflecting surface located at an acute angle to the base of said window and opposite said window whereby Sounds arising from withoutvand tending to enter said window will be reflected outward,
lsaid shield being provided with means adapted to coperate with said window whereby ventilation may be secured.
4. LIn combination, a reflector comprising a series of non-contacting parallel plates arranged at an acute angle to the base of the window and means for supporting them,
wardly and outwardly sounds coming from below.
