CAR CONSTRUCTION.

Specification of Letters Patent.

Patented Dec. 16,1913.

`Application filed November 2, 1908. Serial No. 460,654.

To all whom it may concern Be it known that I, GEORGE H. FoRsYTH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car Constructions, of which the following is a specification.

This invention relates to car constructions,

and has reference more particularly to that type known as convertible cars, which may be operated as closed cars in cold weather, and converted into open cars having side entrances to the seats thereof in warm weather. The purposes, objects, and constructional characteristics of the invention will be readily understood from the accompanying drawings and the following detail description; it being stated that several of the individual features of the invention are capable of application to cars generally, whether of the convertible or non-convertible type.

Referring to the drawingsf-Fi ure 1 is a vertical transverse section throug one side of the car-body and roof. Fig. 2 is an inner side elevation, partly broken away. Figs. 3, 4 and 5 are cross-sectional details, enlarged, on the lines 3 3, 4-4 and 5 5- of Fig. 2, through one of the side posts and the adjacent marginal portion of the closure panels which engage the same. Fig. 6 is a crosssectional view, enlarged, through one of the side posts on the line 6--6 of Fig. 2. Fig. 7 is an enlarged detail view, illustrating a device for both retracting and locking in any adjusted position the panel closure.

Referring to the drawings, 10 designates the floor, 11 designates as an entirety the vertical side wall, and 12 the roof of a car side. The main posts or uprights of the car side are formed principally of a structural steel beam, herein shown as an I-beam 13, which extends from the floor to the median line of the car roof, being suitably bent to conform to the profile of the side wall, roofand deck of the car as clearly shown in Fig. 1; .These posts lie between the usual window-openings; and, according to the width between these openings, will be used singly or in connected pairs. In both cases, a coverin and reinforcement of sheet metal is applie to the beam, as shown at 14 which covering is corrugated on the sides of the posts adjacent to the openings, as shown at 15, in a manner to form guides for the panel closures, as hereinafter more particularly described, and preferably extends only up to the top of the vertical side portion of the ost, a though it might be extended whol y or partially to the median line of the car roof. Where the wall portion between adjacent openings employs a pair of such beams, the covering extends entirely around both, as shown in Fig. 6, in which case an internal reinforcement 16 is employed between and secured to the inner adjacent sides of the posts, together with spacing and filling strips 17 `between the inner adjacent edges of the fianges of the post. That portion of the covering which is corrugated and lies opposite the edges of the post is also preferably reinforced b internal filling pieces 18. The beams 1 are conveniently secured to the longitudinal side sill of the car by an angularly bent extension 19 of the web secured to thelsill as by rivets 20, and further by a bracket 21 riveted at 22 to the web of the beam and at 23 to the sill.

That portion 15 of the covering of the post lying adjacent to the opening between adjacent posts is so corrugated as to form a pair of vertical grooves 24 and 25. Engaging the grooves 24 of a pair of adjacent posts are vertically extending hollow shoes 26 that are formed on their outer sides with beveled or inclined edges 27 engaging correspondingly inclined walls of the grooves 24, whereby said shoes are normally crowded inwardly under a spring action hereinafter described. Between and internally overlapping the inner edges of the shoes 26 is an upper panel closure, which, as shown, coinprises a sheet metal sash frame 28 equipped with double glazingr 29. The latter are secured tightly in tie frame by a pair of triangular-shaped strips 30 and 31, preferably made of bent sheet metal so as to be resllient, said'strips being placed with their inclined sides adjacent to each other, and adapted to be drawn together' by a bolt 32 so applied as to wedge the strips 30 and 3l together and thus securely hold the margins of the glazing. Bow springs 33 interposed between the vertical s1des Q8 of the sash frame and the inner transverse walls of the shoe 26 act to force said shoes into snug engagement with the guide-groove 24. Mounted on the inner face of the shoe 20 is a spring-pressed locking plunger 33 (Fig.

ciently to spring the panelout of engage-y ment with its guide. To provide for a limited raising of the upper panel, where it lies just below the lower edge of the root finish, as shown, the latter may be vertically slotted, as shown at 35, to provide clearance for the Y knobs 36 of the plungers, so that the latter may engage upper sockets 37 in the guide to hold the sash in raised position.

Engaging each of the ll-shaped guidegrooves 25 is 'a hollow shoe 38 having a wedge-shaped outer edge coperating with the walls of the guide, said shoe 38'eXtending from a point substantially opposite the lower margin of the upper panel to the ioor oit the car. Between the opposed shoes 38 and internally overlapping the inner margins of the parallel walls of said shoes is a frame member consisting of a pair of parallel plates 39, the marginal portions of which are bent at right angles, overlapped, and secured together, as shown at 40 (Figs. 4 and 6). 'llhe upper portions of the plate 39 are cut away except at their vertical Inarginal portions, the latter being left to orm with the transverse walls 40 channel-shaped guides 41, in and between which is slidably mounted a sash :frame 42 carrying a glazing 43 that is secured 'snugly at its margin by wedge-strips 44 coperating with an inclined side 45 of the sash trame and secured by bolts 46. 'lhe lower portions of theplates 39 also have rectangular openings cut therein, and the marginal portions of said openings are turned and bent inwardly toward eachother, as shown at 47' (lF ig. 6), their transversely disposed meeting edges being .united by a strip 48 secured thereto, thereby forming grooves with ontw rdly inclined side walls adapted to receive t ie edges of a pair of panel plates 49, the groove-engaging edges ot said plates being bent so as to lie parallel with and against the inclined side walls ont the groove. 'llhe panel plates are secured by a wedge-shaped strip 50, pretern ably made hollow so as to possess a resilient character, located between and with its inclined sides engaging the margins or" the panel plates 49. A bolt 51 passes through the wedge-strip and the transverse wall 'et the groove, and the wedge-strip is drawn inwardly by nuts 52, access being had thercto with a wrench through an opening 53 formed in the transverse wall of the frame. By reason of this construction not only are the edges of the panel plates 49 securely held in place, but, in tightening up the bolts 5l, astrong tension is exerted upon the panel aesinet plates, insuring their smooth and level lappearance, while'tliey are readily replaceable, when necessary, by simply loosening the wedge-strip 50. A

Between the openings4 occupied by the upper glazing 43 and the lower, panel plates 49, the parallel side plates 39 of the frame form a pocket 54 into which the sash frame directly thereabove may be lowered. To lock the sash frame 42 in raised position, 1 secure to one of the side walls of the channel-guide 41 a bracket arm 55 that extends outwardly through a horizontal slot 56 in the shoe 38 and has mounted therein a springpressed plunger 57, the locking end of which passes througha hole in the side of the channelguide 41 and into a horizontal slot 58 in the frame 42. rl`his supports the latter when the plunger is in locking position, while at the same time permitting edgewise movement of the sash, frame 42 relatively to its channel-guide 41; these-latter being normally forced apart by an interposed leaf-spring, 59.

rlhe vertical sides of the frame formed, by the plate 39 are maintained in locked or released position relatively to the shoes 38 by the means shownchiedy in Figs. 5 and 7, these means comprising one or more tensile springs 60 (Fig.'7) that connect the opposed transverse walls of the shoe and frame, tending to draw them together. Applied to these 1walls are a pair of cam- blocks 61 and 62, respectively, the latter bein secured to the wall 40 as by screws 63a, while the block 61 has a sliding engagement with the transverse wall of the shoe 38. "lhe proximate inclined faces of the blocks 61 and 62 are each odset laterally so as to provide a pair oil2 smooth engaging faces 63 and 64, while the offset :Faces are formed. the one with a rack 65, and the other with a smooth surtace 66.

67 designates a key having a toothed head 63 that may be entered through an aperture 69, said toothed head lying between the rack 65 and the offset surface 66 and, when turned, raising or lowering the' cam-block 61, the lowering of the latter locking the panel frame in the shoe and forcing the latter into snug engagement with the grooved guide of the post, and the raising of the block'61 allow-ing the springs 60 to draw the shoe'and-,panel frame together, and thus allowing the frame and shoe to be readily removed from the guides of the posts.

' llhe upper inwardly bent portions of the structural steel beams of the side posts support correspon-din ly bent 'outer and inner A sheet metal sheathing plates 7 0 and 71 forming the roof covering of the car, said sheathing being suitably riveted, as indicated at 72, to the flanges of thbeams. At points opposite the deck sash opening, the sheathing is cut away, portions of the latter 'being bent outwardly and inwardly, respectively, to

noemer form a hood 73 and a deelt-sill formation 74 for the deck sash opening indicated at 75.
