EXTENSIBLE AUTOMOBILE-DOOR.

Patented Dec. 23, 1919.

Application led May 17, 1918. Serial No. 235,11.

I To all whom it may conce/m:

\ ering l tion to be obtained 40" 4covered eert-ain l ments in Extensible Automobile-Doors, of ,which the following is a specification.

' is embodied in Be it known that I, ANTHQNY F. KLEIN- sorrMiDT, a citizen ofthe United States, residing at lIndianapolis, Marion county, and State of lndiana, have invented and disnew and useful Improve- My invention relates to automobile doors. rllhe object of the invention is to provide a door having ,a sliding section therein. The door is particularly adapted for use in cennection with automobiles having touring bodies in which a sash is adapted to take the place of thegusual curtain employed therein, although the invention. is also applicable to cars having convertible topsorx closed bodies. Other objects are to provide a door of this character in which the smooth exterior surface ofthe door body shall be preserved and in which the sash is effectively concealed and protected when lowered; to provide a door, which, when the sash is elevated to closing position, will present the appearance of being formed in one piece; to provide effective means 'for raising and lowthe sash and forholdin it fixed at any desired height by means o the operating mechanism therefor, and` without theV use of auxiliary catches; to provide an effective and easily operated latch handle cooperating with the hollow door and the sliding sash therein7 and to provide means whereb the sash frame may be effectively engage with the sash and at the same time said frame may be adjusted to lit the guiding surfaces of the door between which `it travels, thereby enabling proper compensafor the wear and looseness occasioned by the shocks and Vjars to which v anv automobile door is subjected in usage.

With these objeotsninj view, my

preferableform` in the arrangement and -constructionhereina-fter described and illustrated in the accompanying-- drawings.

ln these drawings, Figure 1 is a side view in elevation of an automobile door partly broken away; right angles to vertical section of the latch operatinghandle; Fig. 4, a detail horizontal section on the line 4:-4 of Fig. l, and Fig. 5, a`detail invention Fig. 2, a vertical section at Fig. 1; Fig. 8, an enlargedV cross section showing a modified construction of stop means for the sash.

Referring to the drawings, 1 indicates the front panel of the body ofthe door which body is made hollow to receive the vertically sliding window sash. Secured to this panel along each vertical side edge, or formed integral therewith, if desired, are rearwardly extending side flanges 2, to which is removably secured a panel 8 constituting the rear wall of the door. This rear wall is spaced from the front wall of the door to provide the chamber in which the sash moves. The walls are provided with border strips fl, projecting inwardly from the outer panel along the bottom and two vertical sides thereof, and a similar border, strip 5, extending along the upper edge of the panel, which latter border strip provides also a housing and journal bearing for the operating shaft of the door raising and lowering mechanism. y

Secured on the opposing inner faces of the front and rear panels of the doors and along the border strips of said panels are vertical guide rails 6, preferably V-shaped with which areadapted to engage complementarily shaped grooves 7 formed in the I tion, and. its inner edges are engaged with the pane by a clamping pressure exerted' against the same through screws l() which pass through one section of the frame and into screw-threaded holes in bosses 11 formed. on the other section whereby the same is 'clamped within the frame by the compression of the latter against the glass. The V-shaped grooves of the frame serve to divide the latter into an inner compressible or clamping section as above described and an inner expansion section 12. This outer section of the hollow frame is adapted to be expanded or contracted to cause it to properly lit the guide rails carried by the inner and outer panels so as to both provide such a free engagement as will enable the sash to move readily and at the same time prevent rattling of the sash. The extent of such expansion or contraction of the frame may be determined by adjusting means consisting in the embodiment herein illustrated of V-shaped wedging members 13 mounted within the frame and extending along the vertical and horizontal .portions thereof.

These wedges are adapted to bear against the inwardly inclined inner walls 13 formed by the depressed grooves in the frame and are mounted in the chambers 12. In said chambers are also mounted in such manner as to be held ixedly by the walls of the chamber, longitudinal blocks or pressure member carriers 14, the inner edges of which enter the V-shaped wedges. Through thesev blocks or strips are adapted to extend screws 15 the inner ends of which are adapted to bear against, wedges 13 and the heads of which screwsare exposed along the louter borders of the frame by means of openings 16 adapted to permitthe insertion of a screw driver to engage the screw. When these screws are screwed inwardly their ends will bear against the V-shaped wedges 18, and force the latter against the inclined inner walls of the chamber 12, thus expanding the wall of said chamber and increasing the cross sectional projection thereof so as to cause the frame to more closely approach the opposing walls of the inner and outer panels of theA door and carry the grooves into closer contact with the rails. The pressure is correspondinglyreduced by retracting the adjusting screws.

Formed in the outer face of each inner vertical section of the sash frame are 'rack teeth 17 with which are adapted to engage respectively pinions 18 carried at the opposite ends of a rotatable shaft 19 which is journaled in the housing` member 5 of the front panel. This shaft is adapted to be operated by mechanism capable of automatically retaining the sash in any position of elevation to which it may be adjusted. The mechanism here illustrated, and preferably employed, consists of a-worm gear 20 fixed on the shaft and adapted-to be engaged by a worm 21 carried on the end of a stud shaft 22 extending through the front panel and having on the outer end thereof outside of said panel acrank 23 carrying a handle 24rwhereby the worm may be turned so as to rotate the shaft and thus through the engagement of the rack and pinion elevate or lower the sash with respect to the door. A stop 25 is provided to limit the upward movement of the lsash and is adapted to engage the bottom rail 25 of the frame. In touring bodies, the sides of the sash frame have no support when the latter is in elevated position, but the support obtained from the engagement of the frame` with the walls of the door and the guide rail is su'icient to hold the sash in an elevated posia piece door when the sash is elevated.

tion. When used with a closed body or convertible top the sides of the sash may engage the usual posts or rigid frame of the body. Owing to the fact that the borders of the sash frame are in substantial continuation of the vertical borders of the door the construction presents the appearance of a rlone ie sash is held automatically in any desired position by the worm and worm gear thus avoiding the necessity of using additional catch means.

The door is provided with'a latch 26 adapted to be operated from ,the outside by a handle 27 of ordinary construction and from the interior by a U-shaped handle which passes down within the door under the space adapted to be occupied by the sash. This inner handle comprises a latch bolt connected member 28, an outer vertical lever 29, a horizontal rocking shaft 30 below the level of the sash, and an inner vertical lever 31 fixed on the rocking shaft and carrying at its upper end a handle 32. By this arrangement the latch mav be operated from the mside without interference with the sash.

In Fig. 5, a construction is shown in which the lower sash rail'and the upper door body rails are wedge shaped, thus providing means for limiting the upward movement of the sash and also increasing the firmness of support of the sash frame by thedoor.

Having thus described my invention, what I claim is:

1. An extensible automobile door having a hollow body, a window therein comprising glass and a metal sash mounted therein and adapted to be projected above said hollow body, said body being provided with guiding surfaces for the frame of said sash, and means for adjusting the sides of said sash toward and from the guiding surfaces to regulate the sliding as set forth.
