SLIIDING-WINDOVY MECHANISM.

Application filed August 26, 1920.

T 0 all whom it may concern f Be it lrnown that l, ELncIn l). FARUM, a citizen of the United States, and a resident of Ualrland, county of Alameda, and State of California, have invented a new and useful VSliding-Window Mechanism, of which the following is a specification.

My invention relates to slidingV window mechanism and particularly to means for preventing the rattle of the slidable windows such as are used on automobile tops.

An object of the inventionv is to provide simplerand effective means for preventing the rattle of windows, which will be automatically placed in operative position or released therefrom by the movement of the sash.

Another object of the invention is to provide means of the character described which may be thrown into operative position or released therefrom at a point intermediate the eXtreme forward or rearward position of the sash by merely moving the latter in one direction or the other.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of my invention which is illustrated in the drawings accompanying and forming part of the specification. lt is understood that l do not limit myself to the showing made by the said drawings and description., as I may adopt variations ofthe preferred form within the scope of my invention as set forth in the claims.

Referring to said drawings:

Figure 1 is aver-tical section of the top of an automobile equipped with slidable windows and the mechanism of my invention. Parts of the inside lining of the top are shown broken away in order toV disclose the construction more clearly.

Figure 2 is a longitudinal sectionof one side of the top, the plane of section being indicated by the line 2 2 of Fig. 1.

Figure 3 is a vertical section of one side of the top taken on the line 3 8 of Fig. 1.

Figure 4 is a side view vof one of the members of the clamping mechanism.

Briefly expressed the mechanism as here shown comprises a window frame in which is arranged a set of sashes supported therein by hangers which slidably engage a perforated track.l Clamping mechanism is arsenal No. 406,172.

ranged on the track and moves with but is normally released from clamped engagement with the sash. Vilhen, however, during the movement of the sash the proper open` ing or perforation in the track is encountered by the clamping mechanism, a part of the latter is permitted to pass through the opening and engage the sash. Thereafter a slight continued movement of the sash will operate to force the clamping mechanism into tight engagement therewith, thereby causing the mechanism and the hangers to be pressed against opposed surfaces of the track with a considerable force. To effect the release of the sash it is only necessary to slide it in the reverse direction. By providing a number of openings in the track the sash may be clamped in several intermediate positions. Means are also provided for enabling the clamping mechanism to pass over the intermediate openings should it be desirable to merely clamp the sash at one or the other of its extreme end positions.

A detailed description of the present embodiment of the invention follows:

The mechanism of my invention. as has been hereinbefore mentioned, is particularly adapted for use in connection with the slidable windows of automobiles and accordingly have shown such an embodiment in the drawings. The body 2 of the automobile here illustrated is of the enclosed type and is formed with the usual top 3 having` a permanent side window t between which and the windshield is the opening 5. The sides of the opening 5 are in the form. of a frame 7 which includes pockets 8 and 9 and in which is slidably disposed a pair of `sashes 11 and 12. The pocket 8 is formed between the permanent window 4 and the inside wall 13 of the top and serves to enclose the sashes 11 and 12 when Vthey are in their rearward or open position. The pocket 9 is formed between the inner and outer walls 13 and 11iat the top of the opening 5 and extends practically the full length thereof. Fixed in the pockets 8 and 9 and spaced from the outer and inner walls thereof is a track 16 formed on itsopposite sides with grooves 17 and 18 in which engage hangers 19 and 21respectively4 that support the sashes 11 and 12. The sash 11 is arranged `to move forward the full length of the opening 5 so that it may close the forward half thereof, whereas the sash 12 is arranged to their extreme end positions as well as at an intermediate position, which will permit the clamping or releasing of the sash, whether at the end or intermediate position by the continued or reverse movement of the sash. F iXed to each sash forlongitndinal movement therewith but slidable transversely thereof is a clamping member 29 preferably disposed between. the hangers and arranged in the grooves of the track. ln the present embodiment of the invention part of the necessary transverse movement of the clamping .member is permitted by forming' it of aresllient material but it is obvious that such movement may be permitted by mounting- 1t 'yielding'ly Formed inthe lower face 3() of both grooves 17 and lSfof the track are a plurality of longitudinally spaced openings 3l in which may enten. so Vas to eifect the clampingof the sash in a manner which will be hereinafter described, one of a pair of arms 32 that is pivoted to the member29.

The arms are preferably pressed by a spring 33 vso that the free ends thereof vwhich are provided with anti-friction rollers 34 will normally bear against the faces 30. T he arm 35 which is pivoted to the clampingmember associated with the sash ll is ada-pted to engage either the openings 37 or 38 thereby allowing the sash il to be clamped in its eXtreme forward position or intermediate position respectively. The other arm 39 of this set is adapted to engage the-opening 41 so that the sash ll may loe-clamped in its extreme rear position. ln a practically similar manner the arms 42 and 43 of the member 29 associated with the sash v12 are adapted 'to engage the openings44 and 45 respectively and thereby clamp the sash l2 in its eXtreme forward and rearward position respectively. By arranging the arms einaffe such an ooenin' whereas the arm' i b Z1 which follows will readily pass over it. In accordance with the ,foregoing as clearly seen inrFigure l, the sides of the openings 37, 38 and 44are sloped downwardly and forw'ardly Awhereas Vthe sides of openings 4lV slope downwardlyand rearwardly. The operation' of the mechanism is as follows: Assuming' that it is desired to move the sash l1 from a rear position to the position shown in Figure l, the sash is moved forward so that the arm 35 on reaching the opening B8 enters it and comes in contact with the top of the sash. When the arm first contacts with the sash top it is forced to assumeA a positionin which its longitudinal axis lies substantially parallel to the sides of the openng. This isdue to thefact thatthe upper surface of the clamping member is already in contact with the upper face 47 of the track groove and thereby prevents the arm from becoming fully extended. However-'upon the vcontinued movement of the sash the arm abuts against the forward side of the opening and causes the clamping' member to flex suiiiciently to Venable the free end of the arm to lie back of a vertical line intersecting its pivotal point-'in which position the clampingmechanism islocked. To release the sash from its clamped engagement with the trackit is merely necessary to move the sash in the reverse directionthus causinpthe arm' and clamping'mem'ber to go through the previous movements in the reverse order.

The top of the sash at the point where the rollers of the arms engage is provided with a plurality of plates 48, one or more of which maybe added or removed should 4it be de'- sired to vary the tension with which the sash is clamped to the frame.

trance of the arms in the intermediate opening 38 when it is desired t'o clamp the sash in its extreme forward position. As Vhere shownthe said means comprises a plate 49 which is slidably mounted in the lower wall of the track. Vso that it can be moved to close the top of the opening and therebypreventV the entrance f the roller, as the arm during the movement of the sash, passes over the opening. The plate 49 is provided with a handle 5l which is disposed to one side f 'the path of the sashll.

While I have 'shown but, one intermediate opening 38 it,is' bvious that the number can be increased in accordance with the number of intermediate psitions it may' be desired. to clamp the sashes;

In testimony whereof, I have hereunto set my hand at Oakland, California, this 20th day of August, 1920.
