UNITED STATES PATENT OFFICE FREDERICK JOSEPH S'IUABT,'OF BIRMINGHAM, ENGLAND, ASSIGNOR OF ONE-HALF TO ARTHUR SAM CHESTON,OF BIRMINGHAM, ENGLAND SLIDING WINDOW Application filed March 1931, Serial ii'o. 520,273, and in Great Britain ApriI 16, 1980.

provide improved and more eflicient means Y 7 Figures 6 and 7 for retaining the window in the position desired.

The invention consists in the provision of a.

cam-bar which isadapted, when operated, to engage the window, or to engage and press in a resilient or angularly-movable side of the guide channel, so as to hold the window in lace.

ccording to the preferred arrangement the edge of the window is arranged to engage and to slide within an inner channel of rubber or other flexible material housed within a rigid outer channel of metal, a cam-bar being provided between the opposed sides of the inner and outer channels. Similar clamping arrangements are provided at opposite edges of the window, the cams at opposite sides being operated simultaneously by a lever. To enable the window to be easily removed the outer channel at each s1de may consist of upper and lower sections fitted with separate cam-bars detachably connected together, so that the upper sections may be removed independently of the lower sections.

Figure 1 of the accompanying drawings is I a horizontal section through a vehicle window fitted in 'guide channels and adapted to accordance with the present invention.

Figure 2 is a front elevation showing the means for actuating the cams.

- Figure 4 represents a cross-section through the channels on a larger scale. v

Figure 5 is asection through the resilient inner channel in its free condition, before being fitted in the metal channel.-

are cross-sections through modifications.

Referring to the form of the invention shown in Figures 1 to 5, as applied-to a slid ing window of a vehicle, the opposite vertical edges of a plain glass window panel 1 are arranged to slide within flexible channels or linings 2 of india-rubber or the like, fitted in rigid outer channels or casings 3 of metal attached to thevehicle body or door frame by screws. The one side of the metal channel 3 1s recessed or pressed outwards to form a housing 4 along its entire length within which bears upon the said wall and'deflects the'same inwards against the face of the glass panel 1, thus clamping the window in any desired position. Preferably the inner rubber channel or lining 2 takes the form shown in Figure 5 when in its free condition before being placed in the inetal channel 3, and-when inserted into the latter its inclined sides are brought parallel, so that'one of these sides exerts apressure upon the cam-bar 5 and holdsit in .place within its housing 4, thus preventing vibration. Also, immediately the cam-bar 5 is returned to its normal position after having been turned about its axis to clamp the window, the deflected side of the rubber channel will spring away from the glass. leaving the window free to slide. -A covering 6 of be clamped in position by cams arranged in plushor other suitable fabric encloses the adhering to the glass.

- rubber channel and prevents the rubber from The metal channels 3 at each side of the window are made in two'lengths or sections, as shown in Flgure 3, their ends coming to- 1 gether at 7, the inner channels being also in two sections.v The end portions of the housings 4, upon opposite sides of the joint 7, are

5 cut away to leave a gap through .which extend bent-up

arms

8, 8, of the

cam bars

5, 5, of the respective sections. These arms '8, 8, are connected by a pin 9, so as to form a crank, the said pin 9 havingreduced ends one of which is riveted to the arm of the lower cam-bar while the other end is an easy and detachable fit in the arm 8 of the upper cambar. Lips or flanges 20 are formed on the gapped ends of the housings 4 to form extended bearing surfaces for the arms 8. The means for operating the cam-bars 5 comprises a central lever 10 pivoted at 11 on a bracket 12 attached tothe garnish rail of the vehicle door by means of screws. Attached to the lever 10 by pivots 13, 14, are two

curved links

15, 15, which cross one another and extend in opposite directions. Their outer ends are formed with eyes or

sleeves

16, 16, in which are fitted pull-

rods

17, 17 the outer ends of which are. provided with eyes 18 engaged by the respective crank-pins 9 at opposite sides of the, window. The inner ends of the rods 17 are adjustably held within and locked to the eyes or sleeves l6 ofthe links by means of nuts 19. I

In operation, when the lever is inthe position shown in Figure 2, the cam-bars 5 are in their clamping position, as in Figure 1, the same deflecting the sides of the rubber channels 2 inwards so as to press upon the face of the glass. Ifthe lever is turned to the left the

links

15,15, are forced outwards in oppo-' site directions and the rods 17 17, by acting upon the crank-pins 9,- turn the cams 5 into their free position as shown in Figure 4, the rubber channel 2 leaving the glass which is free to be raised or lowered but which cannot rattle owing to the cushioning effect of the lining 2. When the lever is moved to the right, into the position shown in Figure 2, the

links 15, '15, are drawn inwards until the pivots .13, 14, are over dead centre, the pull beingtransmitted through the rods 17 17 to the cam-bars 5 which are turned in their the

rods

17, 17 is taken up by the flexibility of the channel 2, but larger adjustments can be made by means of the nuts 19. Rubber bufier sleeves 21 may be fitted upon the rods 17 to prevent them from vibrating against the garnish "rail,and a rubber'bufler 22 may I be riveted to the bracket 12 so as almost totouch the lass and thereby limit and silence the vibrations of the window.

To remove the glass from the window frame it is first lowered to the bottom of its travel and the screws that fix the top sec one side of the rubber channel 2a is arran ed to encircle the cam-bar 5a, and is provi ed with a pocket or housing 23 fitting the correspondingly shaped side 4a of the metal channel 8a and containing the said bar 5a. The latter, however, is a loose fit'in the pocket or housing and is free to turn therein, this free' roviding the turning being facilitated by pocket or housing 23 with an interior lining 24 having a low co-eflicient of friction. As the cam-bar 5a is not in metallic contact with any part no rattle can be produced due to vibration.

According to the further modification shown in Figure 7, the rubber channel is in two parts, namely, a fixed part 26 of rubber or the like comprising one side and the bottom, and a movable part 25 of rubber or other soft material surrounding and moving with the cam-bar 56, so as to turn with the latter within the housing 46 of the outer channel 36. A hole or passage 26 ma run the whole length of the part 25 in or er to give a better cushioning action when the cambar 55 and its covering 25 are turned against the glass. I

If desired, suitable bearings may be provided for the opposite ends of the cam-bars, which may have trunnions or the like.

Instead of the cam-bar being of the particular cam-like section shown in the draw-' ings, it may be of any other cam-like form or of an elongated section so as to be adapted .to be turned angularly to bear against the face of the window, or press the flexible side of a channel member against the same.
