Application filed January 30,1906. Serial No. 298,637.

To LZZ tui/bont it may concern:

Be it known that I, DUDLEY H. FLYNT, a citizen of the United States, residing at Grand Island, in the county of Hall and State of Nebraska, have invented new and useful Improvements in Caboose Signal- Lamps, of which the following is a specication.

My invention relates to improvements in caboose signal-lamps.

The object of my invention is to provide a Caboose signal-lamp having novel means for quickly and accurately displaying forwardly or rearwardly different-colored lights.

The peculiarities of my invention are hereinafter described and claimed.

In the accompanying drawings, illustrative of my invention, Figure 1 isa central vertical transverse sectional view of a portion of the caboose-roof having mounted thereon a signal-lamp of my invention. Fig. 2 is a bottom view of what is shown in Fig. 1. Fig. 3 is a horizontal sectional view taken on the dotted line a b of Fig. 1. Fig. 4 is a horizontal sectional view taken on the dotted line c d of Fig. 1. Fig. 5 is a front elevation view of the signal-lamp, part of the roof .being shown in vertical section and part broken away, the lamp-supporting device beingshown in the lower position. Fig. 6 is a side elevation view of the lamp-support shown in the horizontal position and a portion of the mechanism to which the lamp is attached. Fig. 7 isavertical cross-section view of a portion of the support for the tubular frame, one of the frame-rollers being shown in elevation and mounted on said support. Fig. 8 is a vertical sectional view taken on the dotted line ef of Fig. 7.

Similar characters of reference denote similar parts.

1 denotes a portion of the caboose-roof, and 2 two of the transverse rafters thereof.

3 denotes a rectangular casing mounted on the roof and provided with an open-lower end registering with a vertical hole 4 in the roof 1. The casing 3 is provided in its front and rear sides with the openings 5 and 6, respectively. Rotatively mounted in the casing 3 is a vertical, tubular, cylindrical frame 7, supporting four vertical light-transmitting

devices

8, 9, 10, and 11, respectively, said devices being preferably of glass, the device 8 being preferably red in color and the

devices

9, 10, and 11 made of. green glass. Said colored glasses are disposed so as to register each with the openings 5 or 6 when the frame 7 is rotated to the proper positions. The frame 7 is provided with four peripheral projections 12, on which are mounted, respectively, the rollers 13, mounted upon a support comprising the following described mechanism: 14 denotes a substantially horizontal plate secured to the under side of the roof 1 and provided with two vertical flanges 15, secured,respectively,to the two rafters 2. The plate 14 is provided with a central opening through which the frame 7 may be inserted and is also provided with a series of recesses communicating with said central opening and adapted to be closed by a series of closures 16, respectively, comprising each a horizontal slidable plate mounted upon the upper side of the plate 14 and provided each with an upwardly-extending iiange 17, adapted when the closures are in the positions shown in Figs. 2, 3, 4, and 7 to form with the upwardly-extending flanges 18 on the plate 14 an annular track upon which the rollers 13 may travel when the frame 7 is rotated. Secured to the inner periphery of the frame 7 adjacent its lower end is a iat spring 19, the free end of which has secured to it a right-angled wire 20, having one vertical leg and a horizontal leg adapted to enter either of the openings 21, provided in three of the iianges 13,. as shown in Fig. 3. The horizontal portion of the right-angled wire 20 extends through an opening provided therefor in the frame 7. By swinging the free end of the spring 19 inwardly the horizontal arm of the right-angled wire 20 is released from the Harige 18, in which it is engaged, after which the frame 7 may be rotated upon its supporting-rollers 13 to the position desired. The plates 16 are slidably mounted each between radially disposed IOO said plate is in the inner position. By pulling downward the free ends of the springs 25 the pins 26 may be withdrawn downward to a position in which the plates 16 may be retracted, together with their fianges 17, to the position indicated in dottedlines in Fig. 7, in which position the rollers 13 will pass through the recesses normally closed by the plates 16, thus permitting the frame? to be inserted into or withdrawn from the casing 3.

27 denotes the cylindrical lamp-reservoir, mounted centrally in the casing within the frame 7 and in a position such that the burner 28 will be disposed between the openings 5 and 6.

. 29 denotes a flap comprising, preferably, a metal plate hinged at one edge by means of a plate 30 to the under side of the plate 14. The plate 29 is provided at its inner end with an upwardly-extending curved flange 3 1, partially encircling the lamp-reservoir 27 and having hinged to it at one end a curved plate 32, which encircles the opposite side of the reservoir 27. The free ends of the plate 32 and the flange 31 are releasably secured together by means of a bolt 33, extending through said flange and plate and having mounted thereon a securing-nut 34. The plate 29 is secured in the horizontal position by means of two turnbuckles 35, rotatively mounted on the under side of the plate 14 and adapted to be turned, as shown in Fig. 2,

to a position in which they will engage and lock the plate 29 in the horizontal position. Diametrically opposite sides of the plate 32 are provided with vertical slots 36, extending upwardly from the lower edge of said plate and provided each with a horizontal recess 37. The reservoir 27 of the lamp is provided on diametrically opposite sides with pins 38, adapted to be slipped upwardly in the slots 36 and laterally into the recesses 37, so as to support the lamp.

The burner 28 is mounted in a horizontal barrel 39, having its two ends closed, respectively, by the two lenses 40, disposed, respectively, in aXial alinement with the openings 5 and 6. The barrel 39 is provided in its upper end with a chimney 40', which chimvney discharges the products of combustion through a vertical opening 41 in the top of the casing 3.

Suitable housings

42 and 43 of any desired construction are employed to protect the inner and outer portions of the casing, respectively, from the products of combustion passing from the chimney 40. The housing 42 is tubular in form and has its upper end secured to the under side of the top of the casing and encircling the chimney 40 and opening 41. The housing 43 is mounted upon the top of the casing encircling the opening 41 and is closed at its upper end, the lower end being open and registering with the opening 41. Peripheral holes 44 are provided in the housing 43 to permit the escape of the products of combustion. The lower side of the barrel 39 is provided with a vertical tubular extension 46, adapted to be inserted between the plate 32 and the flange 31. The tubular extension 46 is provided with two diametrically opposite slots 47, eX- tending upwardly from the lower edge of the extension and having each a lateral recess 48. When the parts are in the position shown in Fig. 1, the

slots

36 and 47 andrecesses 37 and V48 register with each other, so that the lam reservoir 27 may be slipped upwardly to t e position shown in Fig. 1, in which position the pins 38 will be located in the

recesses

37 and 48.

In operating my invention, the parts having been assembled as shown in Fig. 1, when it is desired to change the signals the vertical arm of the lright-angled wire 2O is swung inwardly, together with the free end of the spring 19, after which the frame 7 may be swung to a position in which the proper colored glasses will be interposed between'the openings 5 and 6. To remove the lamp for the purpose of filling the reservoir with oil, the reservoir is turned to the left until the pins 38 are in alinement with the

slots

36 and 47 ,-a'lter which the reservoir may be withdrawn. If it is desired for any reason to remove the frame 7, the lamp is first removed, after which `the nut 34 is removed from the bolt 33, the bolt 33 is withdrawn, and the plate 32 swung so as to clear the extension 46. The turnbuckles 35 are then turned, so as to permit the plate 29 to be swung to the position shown in Fig. 5. The barrel 39 may now be removed. The plates 16 are then withdrawn outwardly, the springs 25 being depressed for that purpose, and the frame 7 is then turned until the rollers 13 register with the recesses normally covered by the plate 16, in which position the frame 7 may be withdrawn.

Various modifications of my invention may be made without departing from its spirit.
