RAYMCND L. GOOCE, F FALMO'GTH, MAINE, ASSIGNOR 0F ONE-HALF TO STANLEY J. MAYHEN, OF SOUTH PORTLAND, MAINE WIN DOW SCREEN Application filed April 7,

The invention to be hereinafter described relates generally to that well known device a window screen. in the present instance this screen, due to its embodying certain novel features in its structure, is particularly well adai ited for use in the windows of motor vehicles, and, although its primary object is in line with that ol the ordinary house window screen, that is, to provide protection against lit mosquitoes or other insect pests, it is suscep -e serving in other capacities which will he more fully dealt with as the description of the device proceeds. I v

Among the more specific objects and advantages of the invention, speaking in terms of structure, are:

1,, The wedge shape rails, or marginal portions on three sides of the screen, insuring tight fitting joints between the screen and the window frame, regardless of the width of the groove in which SlltlGS the window pane.

A bottom rail which encompasses the top of the window pane and allows the latter, when raised, to force the whole screen upwardly and bring the top rail to a close tit within the upper groove in the window frame.

3. An automatic locking device which holds the two sections of the screen extoncled into the side grooves of the vehicle window frame. 4. Thelocating of this automatic locking device so that it operates on the inside of the vehicle only, largely doing away with petty thievery of articles left in the vehicle when parked on the street or highway, and

5. The small space required to store the screen when not in useone portion telescoping the other and reducing its normal length by nearly one-half. The character of the invention may best be understood by reference to the description found in the specification following when taken in connection with the accompanying drawing in which is disclosed one embodi ment which, at the present time I consider preferable to other possible forms in which the invention might be carried out.

In the drawings Fig. 1 is a side elevation of my screen;

Fig. 2 is the same, showing the screen 1930. Serial No. 442,234.

sections of the screen including the locking device which holds the parts extended;

Fig.6 is a view showing a detail of the juncture of he side and bottom rails;

Fig. 7 shows a screen, in fragmentary form, mounted over a window pane of arcuate shape on its upper ed e, and

Fig. 8 is a section talcen on line 8-8, Fig. 7.

Similar reference characters are employed to identity like parts in all Views of the draw ing.

In Fig. 1 is shown a full side View of my vehicle window screen. It comprises two sections, A and B, the top and bottom rails of one section telescoping those of the other.'

The method of attaching the screen cloth 10a and 107ito the frame work of the respective sections, A and B is, in the present invention, not of material importanceany approved way may be adopted, but as shown it consists in partly shearing a plurality of tongues T through the inwardly disposed flanges of the rails and subsequently forcing these tongues into the depression made by the shearing. firmly engaging the screen cloth interposed between the tongue and llange. This is clearly shown in Figs. 5 and 6.

In Fig. 3 is shown a transverse section, vertically of the screen, illustrating the crosssoctional shape of therails composing the frame work of the screen, the latter being disposed within the window space of an automobile door D, the frame 11 of which is provided with a groove in which slides the window pane P.

The rail 12a of the outer screen section A is made wedge shape-both sides flaring inwardly to form an apex which enters the window pane groove. Thus when the rail is forced upwardly into the groove 13 it centralixcs therein and bears strongly on both corners of the groove ell'octing a close joint no a between the screen and window frame, and this regardless of slight variations in the width of the groove.

The rail 12?) of the telescoping section B snugly tits the inside of the rail 12a and its flaring edges also hear, fora greater portion of its length, on, the corners of thegroove'18- there being, in any event, a space near the overlapping point of the two rails insuiii cient to permit of the smallest-fly or mosquito to enter or pass through.

The side rails 14a and 14?), being of the same type as the

rails

12a and 126 the same conditions obtain with respect to the tightness of the joint made in the side grooves 15 when the sections A and B, respectively, are extended.

.The bottom rails of the two sections are dillercntly constructed. In Fig. 6 is shown the lower, left-hand corner of section A and it will be observed that the rail 16a forms an integral part of the vertical, side rail 14a: and, preferably, is slightly concaved so as better to receive the upper edge of the window pane when raised to engage the screen. The cross-sectional shape of the

rails

16a and 166, however, is really immaterial so long as a proper joint is provided between the rails and the window pane.

In Fig. 7 is shown a condition in which it is essential that the bottom rails, 16a and 166, be madewith overhanging sides so as to encompass the arcuatetop window pane for its entire length. The cross-sectional view in Fig. 8 discloses the preferred form in this particular instance, and. so as to permit of the. rails telescoping, they are made straight+as depicted in Fig. 7.

' ne meritorious feature of my screen is the automatic or self-locking.mechanism, illustrated. in Figs. 1 and 5. Extending out wardly from the.inner upright, 17b, of the section B, is a channel portion 18, piv'otedon which is a pawl 19. On the rail 16a is an upwardly extending flange 20 provided on its top edge with a rack 21. When the two sections are extended or moved outwardly, the pawl engages the teeth of the rack in successive order until the rails 14a and 14?) are firmly seated in the grooves 15. The two sections can now be retracted or brought together only after lifting the pawl out of the rack. A spring 22 tends to keep the pawl engaged, and the arm 19' serves as means by whichto lift it.

In attaching accessories to any portion or part of an automobile one of the most essential precautionary measures which should be takenis to provide in so far as isipossible against loosening of connections or-rattle of the parts this trouble of noise being highly objectionable to most individuals.

The principle involved in the=method by which I obtain a vibration-proof installation of myscreen on a moving bodyas a motor" grooves of various vehicle, can be carried out, I believe, in no other way so simple as the wedge-shape form of the top and side rails, except, of course, resort be had to belts or other clamping means, which in this class of device would be hardly feasible.

- The rails are self-centering in the window pane grooves, are slightly fieznble when coming to a seat therein, and in so far as fitting widths are universal in character. When brought to their extreme limit of movement the sections are automatically locked by the self-locking mechanism, which being accessible only from the inside of the vehicle provides a somewhat restraining influence on thoseindividuals who otherwise might be tempted to commit theft of articles left within the automobile.

Furthermore it is of considerable advantage to a business man after parking his car in the street on a hot day to be able to secure a considerable amount of protection of his property and still obtain the benefit of seating himself in a thoroughly ventilated vehicle when he again wishes to use it.

The device can be installed on the automobile in a few seconds of time-and as quickly removed.

Having thus described my I claim and desire to secure cut is 1. An extensible window screen having two telescopically arranged sections, a wedgeshaped rail disposed on three edges of the screen when the sections are assembled, and means to prevent retraction of said section one within the other, after being extended into any one of various positions, relatively.

2. An extensible window screen, adapted to operate within the window frame of'a motor vehicle, the edges of said screen adapted to engage the window pane grooves therein, comprising two telescoping sect-ions, one slidable within the other, each section including a frame,

3. A window screen adapted to operate in a grooved window-frame, comprising two screen sections susceptible of extension and retraction with respect to each other, a wedgeshaped rail projecting from two adjacent edges of each of said sections-the rails on the upper, longitudinal portions of the respective sections making mutual and slidable engagement, a rail on the bottom longitudinal portion of each section of slightly arcuate form, said bottom rails being in. slidable engagement, relatively, a rack on one of said sections. a pawl on the other of the said sections adapted to engage said rack, and means "ill extended portion projecting from the lower,

normally holding said 4. In a device of the character described, adapted for use in a window frame havin relatively wide grooves in three sides thereo for the purpose of receiving a vertically slidable window pane, comprlsmg 1n combination,.two extensible screen sections, a rail on each of said sections, of wedge-she form, the base of the wedge being greater in width than that of the said grooves, said rails being disposed on the vertical, outer edge and across the upper longitudinal edge of each section, said upper rails of the two sections making mutual and slidable en agement, a base rail extending from the ower portion of each section, said rails slidably engaging each other and adapted to be engaged by the said window pane, when raised,

and means to secure said sections so that the vertical, wedge-shaped rails may be held in close engagement with said grooves.

5. A device of the character described, adapted to be mounted in the grooves for the window pane of a motor vehicle window, comprising in combination, two gnomonic shaped frames disposed, laterally, in slightly spaced relation, screen cloth secured to. said frames, and covering the interior space therein, an extended portion projecting outwardly from two adjacent ed es of the frame of each of said sections, sai portion being bent into the form of a wedge-shaped rail, the rails running longitudinally of the sections being in close and slidable engagement, relatively, an

longitudinal part of each of said frames, bent to form a rail adapted to be engaged by the vertically movable window pane of said motor vehicle and so formed as to enclose the top and a portion of each side of said pane, said last mentioned rails being disposed in relatively slidable engagement, a toothed rack on one of said sections, a pawl on the other of said sections adapted to engage said toothed rack and revent retraction of one section into the ot er, a spring operable to normally hold said pawl in engagement with said rack, and an arm on said pawl by which to lift it out of engagement with said rack.
