T0 all wh0m it mag; concrn:

Be it known that I, THOMAS A. JOHNSTON,

of Fremonr, in the county 0f Dodge and State 0f Nebraska, have invented certain usefu1 Improvemen!s in Gab 0r Gar Awnings; and 1 do hereby declare that the following is a, full, e1ear, and exact deseription 0f the invention, such as will enable others skilled in the art to which it appertains to make and use the Same, referenee being had to the accompanying drawings, which f0rm a part of this specification.

This imention has relation t0 a new and novel collapsible awning, adapted t0 be used 011 locomotive cabs and railway cars and eoaches.

In the acoompanying drawings, Figure 1 shows a b0tt0m view of my improved awning, as extended and open. Fig.2 shows afront view 0f Fig. 1, showing a portion of the 1000- motive cab. Fig. 3 is an end view of Fig. 2. Fig. 4 is a broken section of the spring actuated curtain roll; while Fig. 5 shows 1ny improved curtain in a c1osed condition.

A represents the cab 0f a locomotive as usually constructed t0 whieh my curtain is t0 be attached.

In securing my device to a locoxnotive or car I prefer attaching the same 120 a panel B, of any snitable length and material. T0 this panel is secnred my improved cnrtain.

2 represents the end caps0f the roll 5, giving supporo t0 the curtain 6. This roll is an ordinary spring actuated curain roll, as is usnally employed, an 1 the 6, may be of any suitable material, such as 011 cloth or canvas. T0 the free end I secure a rod 7, as shown.

3, 3 and 4, 4, represent the bearing ears, by 1neans of Which oho rods eornprising my improved frarne are hold.

Seeured t0 the rod 7, are tw0 depending clamps 8, the lower portions 9, 0f which are reenrved so as t0 give Support to a depending panel 30. The elamps 8, are provided upon the rear With an ear 11, adapted 130 engage the nut 12, and this ear 11, forn1s the clamp in conjunetion with the bar 8. This clamp is adjustable upon the frame and rnay be seeured at any snitable point.

Seeured t0 the ears 13, are the rods 14, 14, and 15, 15, which are articulated and a1e adapted t0 f0ld upon one -another bu1: which when opened will b0 held in a straight line, as shown in Fig. 1, in the manner 0f a hinge; these rods 14 and 15, really aotnating si1rnilar to a hinge.

17 represents a transverse bar, which is secured. t0 the rods 14. By rneans of the pins 16, to the ears 4, 4, are secnred the slotted trigger bars 20 and 26, whieh slide npon the bars 4 by means of pins 21 and 27. The trigger bar 20 is conneetaed 130 the bars 17 by rneans of the conneeting rod 18, while the trigger bar 26 is eonneeted t0 the bar 17 by means 0f the rod 28, working within one end of the pi voted lever arm 22, and then being conneoted-to the rod 17 by means of the intermediate rod 19.

The ear 24, is extended by means ofthe bar 25, whieh forms parl. 0f the ear 4, as is shown in Fig. 2, the bar 25 and 25' being in one piece and giving Support at the end to the slotted trigger bar 26, by means of the bearing ear 24.

T0 further secure the awning and prevent the wind from carryingit upward 01 sidewise, I provide the ohains 33, 33, and 34, which are seeured to the sides 0f the cab 01 0ar. The chain 34 is preferably hooked over the r0d 7, and below is seoured to the ring, 35.

The pane1 30, which depends froxn the awning, is adapted 110 prevent the sun from entering through a.nd is secured 110 th0 adj ustable clamps 8, by means 0f an ordinary thumb serew 40, and the transverse bars 41, so that this panel can be readily removed if desired.

The Operation of my device wou1d be as E01- lows: Ifa car or Gab equipped with my improved awning shonld enter a bridge whieh wonld n0t perrnib the extension of the awning, the trigger bars 20 01 26 wou1d corne in collision with the bridge post or any other 0bbe forced in a direetion opposite and so earry the rod 19, outward, and tbis rod 19, wou1d upse't the hinged articulated rods 14 and 15, and so permit the spring actuated roll 5, to instantly ooil up the curtain a.nd so earry it out of the path of the obstruction before the curtain cou1d be injured. In this position the eurtain would be nieely folded againsb the car, as is shown in Fig. 5. If the cm shou1d go in the opposite direction the trigger bar 20, wou1d be encountered, when the device wou1d be more promptly closed, as there are no intermediate rods 01' levers necessary to bring about this effect.

The device is exeeedingly simple and is adapted to be used in eonneetion with any ordinary car, eoach 01 vehiqle; and,

Having thus described my said invention, what I claim as new,'and desire to secure by United States Letters Patent, is

1. In a eollapsible awning, the combination with a suitable supporb, of a spring actuated roll, a curtain seeured t0 Said roll, articulated rods suitably supported and secured a1; their outer ends to the free end of said eurtain, und two slotted trigger bars secured 'co said articulated bars, to upset and close said bars and ci1rtain, all substantially as and for the purpose set forth.

2. The combination in acollapsible awning 0f a. suitable supporting panel, of a spring actuated roll, acurtain secured to said roll, provided at its free end with suitable elamps, articulated rods seoured t0 said clamps and working within suitable ears, a transverse bar connecting said articulat-ed rods, and two slotted trig'ger seeured 130 said articulated rods by means of suitable connecting bars, one of said trigger bars being provided with an intermediate 1ewer and rod. so as t-o upset said curtain when said trigger bars am cmlied out of position, all substantially as and for the purpose set forth.

3. In acollapsible awning, the eombination with a suitable supporting panel, of the supports 2, 2, the supporting ears 3, 3, and 4, 4, the spring actuated roll 5, provided With the eurtain (i, provided ab its free end with the rod 7, elamps 8, provided ab their lower ends WiLh recurved portions adapted t0 removably hold a pa'nel, the articulated hinged bars 14 and 15, seeured to the clan1ps 8, and the ears 3, and tl1e two slotted trigger bars 20 and 26, the slotted bar 20 being connected to the transverse bar 17 by means 0f the IOd. 18,
