Patented July 15, 1930 WILLIAM S. PRITCHARID, OF DETROIT, MICHIGAN, ASSIGNOR TO MOTOR PRODUCTS OORPORA'IION, OF DETROIT, MICHIGAN, A CORPORATION OF NEW YORK PULLMAN WINDOW Application filed. February 27, 1928.

The invention relates to window construction and more particularly to an improved means for detachably securing the glass panel within the sash.

The invention has as one of its primary objects to provide a window of the above type distinguished by its simplicity of construction and facility with which the same may be attached to the standard car construction and with which the usual glass panel may be installed, all of which not only enhances its value both mechanically and commercially, but provides a design of a strong and durable nature.

The invention finds particular utility in Pullman car construction wherein it is necessary to frequently replace the glass panel due to breakage or other defects. In the particular type of window now more or less universally employed, serious disadvantages have been commonly experienced in assembling the glass panel in the sash owing to the various complicated means utilized for this purpose. The present invention as briefly outlined above ofiers the possibility of eliminating complicated and inefficient securing means for the glass and renders possible the production of a commercially satisfactory window construction in which the glass panel may be readily installed.

It is a further object of the present invention to provide a construction wherein the glass panel securing means not only func tions to detachably hold the glass panel in position within the sash, but also cooperates with a portion of the Pullman car to accu rately guide the window during the opening or closing of the same.

While in particularizing upon the advantages and features of the present invention, particular stress has been placed upon the association of the window with Pullman cal construction. It will be immediately apparent to those skilled in this art that the invention may be used in whole or in part in connection with various other forms of constructions where windows are desired.

Many of the advantages and much of the commercial value and acceptability of the invention is attributed to the construction Serial No. 257,485.

of the sash, these advantages being obtained particularly because of the simplicity, of the construction and the minimum number of parts employed for securing the glass panel in place. The invention therefore depends for some of its advantages upon the specific details of construction illustrated and about to be described.

Other objects and novel features of construction will be made more apparent as this description proceeds especially when considered in connection with the accompanying drawings wherein Figure 1 is a side elevation of a window constructed in accordance with my invention,

Figure 2 is a sectional view taken on the plane indicated by the line 22 of Figure 1,

Figure 3 is a sectional view on the line 83 of Figure 1.

Figure 4 is a sectional view on the line 4.4 of Figure 1.

Referring now to the drawings, it will be noted that there is illustrated generally a portion of a standard Pullman car construction in which 10 is a pillar having secured upon the outer surface thereof, a. substantially U-shaped reinforcing member 11 terminating in the lateral flanges 12 and 13. Spaced inwardly from the front face of the pillar and secured to the side surface 14 thereof is a guide member 15, which as shown cooperates with the lateral flange 12 to form a run-way 16 for the vertically movable glass panel 17 constituting the outer window of the Pullman car. The inner window 18 being slidably mounted in the runway 19 formed by the inner surface of the guide 15 and the usual latch rack 20.

Referring now to the particular construction of the sash members 21 and 22 for the inner and outer windows 17 and 18 respectively, it will be noted that these members are preferably constructed of sheet metal and are provided with stiles 23 and upper and lower rails 2% and 25 respectively, which as shown are substantially channel-shaped in cross section and are secured together in any suitable manner such for example by means of the corner brackets 26. The outer walls 27 and the inner walls 28 of the rails and stiles of the outer and inner sash members 21 and 22 respectively are bent inwardly intermediate the ends thereof as indicated at 28 forming shoulders 29, which as shown terminate in open return bent portions 30, while the inner walls 31 and the outer walls 31 of the stiles and rails of the outer and inner sash members 21 and 22 respectively are formed with an L-shaped rabbet 32 for receiving the usual packing for the glass panel and terminate in open return bent portions 33. The outer ends 34 of the portions 33 projectinto the open return bent portions and the outer ends 35 of the return bent portions 30 project into the open return bent portions 33 so that an interlocking engagement is accomplished between the opposite walls of the rails and stiles. Thus from the fore going, it will be immediately apparent that the rails'and stiles are formed of a single piece of metal bent to form a closed channel and have the opposite ends thereof held in interlocking engagement. The bottom 36 of the lower rail of the sash 21 is bent upwardly as indicated at 37 forming a longitudinally extending pocket 38 for receiving a suitable weather excluding strip 39 having the projections 40 arranged to engage the stool 41. This lower rail is also provided with the usual sliding ventilator construction indicated generally at 42. To prevent rattling of the windows, I provide the anti-rattler members 43, which as shown are of the usual construction and are secured to the stiles adjacent the outer edges thereof, and are arranged to yicldably engage the outer and inner walls of the guide member 15.

In order to provide a neat construction and at the same time effectively secure the glass panel within the sash, I provide the glazing strips 44 and 45 secured respectively to the outer walls of the rails and stiles of the sash 21. The rails and stiles of the inner sash 22 are also provided with glazing strips 46 and 47 respectively, which as shown are secured to the inner walls of the stiles and rails. The strips 44 and 46 are provided at one end with the packing engaging portions 48 and at the opposite ends with the lateral projections 49 arranged to seat upon the shoulder 29 and engage the return bent portions 33. The strips 45 and 47 which are secured to the stiles of bot-h the inner and outer sash members 21 and 22 differ from the strips 44 and 46 in that they are provided with return bent portions 50 and 51 intermediate the ends thereof. These return bent portions engage the shoulders 29 of the stiles and abut the return bent portions 33 thereof and terminate in

lateral flanges

52 and 53 respectively, which as shown are positioned adjacent to and spaced laterally from the

walls

27 and 27 of the stiles. The flange 52 extends across the outer surface of the flange 12 and is provided with a longitudinally extending bead 53 having a bearing engagement with the outer surface of the flange 12 to accurately guide the window during openingor closing of the same. IVith such an arrangement, the amount of frictional resistance between the relatively removable parts is reduced to a minimum owing to the fact that the inner arcuate surface of the bead is-the only part of the flange 52 that actually engages the flange 12. It will further be noted that the flange 52 is of substantially the same length as the window and is reinforced at the lower end thereof by means of the clip 54 secured to the bottom rail of the sash 21 and having a portion 55 embracing the flange 52. The flange 53 of the inner glazing strip also serves as a guide for the inner window and is provided with a longitudinally extending head 56 arranged to engage the outer surface 57 of the latch rack 20. The flange 53 in addition to cooperating with the latch rack to accurately guide the window also functions to fill the space between the stiles of the sash 22 and the latch rack.

For securing the glazing strips to the stiles and rails, I provide headed elements 57 extending through threaded apertures 58 formed in the glazing strips and anchored in the return bent portions 30 and 33 of the stiles and rails. As shown the headed elements are provided with an enlarged threaded portion 59 and a reduced shank portion 60, the latter having a length substantially greater than the length of the threaded portion. \Vith this arrangement, when it is de sired to remove the glazing strips, it is not necessary to remove the headed elements from the strips but merely to unscrew the same from the stiles anl rails. Thus the danger of the elements working loose and becoming lost is eliminated and the attaching and detaching of theglazing strips is greatly facilitated If, however, it is desired to remove the ele' ments from the strips, the former are merely backed out through the threaded apertures 58. It will also be noted that the elements 57 upon threadedly engaging the return bent portions 30 and 33 engage four thicknesses of metal, thereby providing ample threads for these elements so that the latter may be securely tightened to rigidly secure strips upon the stiles and rails.

As described the window is of simple construction and of a minimum number of parts, it being noted that the glazing strips 46 and 47 in addition to securing the glass panel in position cooperate with portions of the car to accurately guide the windows during the sliding movement of the same.
