SAFETY-WINDOW FOR LOCOMOTIVE-CABS.

' Specification of Letters Patent.

Patented Dec. 9, 1919.

Application filed October 7, 1918. Serial No. 257,164.

To all whom it may concern:

Be it known that I, EDGAR M. JUTKrNs, a citizen of theUnited States, residing at La Junta, in the county of Otero and State" of- Colorado, have invented certain new and useful Improvements in- Safety-Windows for Locomotive-Cabs, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in safety windows for locomotive cabs, and it is an, object of the invention to provide a window of this general character having novel and improved means whereby the same may be readily and conveniently moved into an open or closed position in accordance with the occasions of practice so that an engineman within the cab may have a clear vision of the trackway in advance of the locomotive.

It is also an object of the invention to provide anovel and improved window of this general type which may be easily opened and closed with but little exposure of the engine crew to the elements, and which fully meets with the requirements of the Interstate Commerce Commission of the United States. 7 Y r A further object of the invention is to provide a window of this general character having novel and improved means whereby a broken glass may effectively and quickly be replaced. p

The invention consistsin the details of construction and in the combination. and arrangement of theseveral parts of my im: proved window, whereby certain important advantages are attained and. the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be better understood, I will now. proceed to describe the same with reference to the accompanying drawings, wherein: p

Figure 1 is a fragmentary View partly in elevation and partly in section illustrating a safety window constructedin accordance with an embodiment of my invention, the window being in an open position: a

Fig. 2 is a fragmentary view partly in elevation andpartly in section illustrating my improved window in closed position;

Fig. 3 is an enlarged sectional view taken through my improved window as herein described;

Fig. 4 is a view partly in elevation and partly in section illustrating the operating member herein employed; I

Fig. 5 is a View in top plan of the link included in the operating mechanism of the window.

Fig. 6 is a view in elevation illustrating a modified form of frame adapted to be em ployed in connection with my improved win dow, a part being omitted; and

Fig. 7 is a fragmentary view in elevation of the inner face of the outer portion of the frame as illustrated in Fi 6.

While in practice two wlndows constructed in accordance with an embodiment of my invention are tobe employed, one at each side of the cab, the present disclosure is limited to but one window and its concomitant parts. 7

As disclosed in the accompanying draw ings, D denotes a door of a well lmown type and which is arranged at the front of a locomotive cab at one side thereof, and which is provided with a window opening W which permits a member of the engine crew to have a clear vision of the trackway in advance of the locomotive. Coacting with the window W is a safety window S mounted for swinging movement in a horizontal plane and which moves into open position in a direc tion opposite to the movement of the door D when being opened. In other words, the window swings in a direction away from the boiler. of the locomotive so that when the window S is opened or partially opened, the draft entering within the cab through the opening W will be deflected by the window S toward the boiler so that the engineman will be protected against the resultant draft.

In the present embodiment of my invention the window S has an end portion suitably secured, as at 3, to the flattened portion 2 of the vertically disposed rock shaft R, so that the window S will move in unison with and in the same general direction as the rock shaft.

The shaft R is rotatably supported at its opposite end portions by the bearings 4L bolted or otherwise affixed to the top and bottom portions of the frame of the door D. p The shaft R is held against endwise move ment through the medium of the .oollars 5 arranged upwardly of the bearings 4 and said collars 5 are aflixed to the shaft R by the cotter pins 6 directed through the collars and the shaft R.

In the present embodiment of my invention the upper end portion of the shaft lt is provided with. a rock arm 7 terminating in anupstaniling extension 8. The extension 8 is loosely directed through an eye 9 formed at one end portion of a link 10, and said link is held in applied position relative to the extension 8 through the medium of a collar 11 fixed. to said extension below the link through the medium of a key 12.

The opposite end portion ofthe link is also provided with an eye 13 which extends 15 within the kerf of the forked or bifurcated end portion of an elongated member or rod 15. Carried by the forked or bifurcated end portion of the member or rod 15 is a pin let which is loosely directed through the eye 13 so that upon endwise movement being impartedto the member or rod 15 the rock shaftR will be caused-to rotate through the medium of the linklO and the rock arm 7.

The major portion of the member or rod 15 is round incross section, and the end ortion of said member or rod remote from the shaft R is flattened as indicated at 17. Boltedor otherwise secured to the portion 17 of the member or red 15 is a depending operating member M substantially at right angles to the member or rod 15.

The member M comprises an elongated member bent into the form ofa' U with the upper or freeend portions of the side members 18 overlyingthe opposite sides of. the portion "17 of the. membenor rod :15, and secured thereto by the bolts 19 or the like.

The member M affords a loop which bridges the horizontally disposed plate 20 secured at its opposite end portions to the blocks 21 suitably anchored to the adjacent side or wall vofthe cab. The side members 18' of the member M are maintained in fixed spaced relation by the bolts-22, and one of said: bolts is adapted to seat within the notches 23 and, prodncedin the upper marginal portion of the plate 20, andwhich seats within said notchesby gravity. The coaction between themember M and the plate 20 permitsthe window S to be effectively-locked llll closed or full open position, or: in various intermediate positions.

Suitably secured to thelower end. portion of the memben M is a filler block a 24: which isshapedtoa-lford a "comfortable hand grasp or hold so that the desired endwise movement maybe imparted to the member or rod 15 by a member of the engine crew with convenience and facility. 7

The-memberor rod 15 is also slidably disposedthroughaguide 25 suitably attached to the adjacent side or wall of the cab, and which serves' as a support for the forward end portiomof saidmember or-rod lo. 1t 65 will be self-evident that the coaction between the member M and the plate 20 will result inthe desired support for the rear portion ofsaid member or rod 15.

Ashereinset forth, the safety window S comprises a frame F substantially U-shaped in form. with longitudinal. membersa horizontally disposed. The adjacent marginal portions of the frame are defined by inwardly directed flanges 26 and the outer end portions of the flanges of the side members a are connected by the transversely disposed member 27 substantially U-shaped in cross section and having the outer side member Z) V of less width than the inner side member 0 so that the insertion or removal of'the glass panel P may be facilitated and with the possibility ofbreakage of said panel during its insertion or removal in the frame 25 substantially eliminated.

The lass )anel P when aolied has an end portion disposed between the members Z) and 0 of the member 27" and also bears against the flanges 26.

Between the longitudinal flanges 26 is a yokeQS having its free end portions pivotan ally engaged with said longitudinal flanges 26 through the medium ofclamping bolts 29 and the intermediate portion 30 is defined by an inwardly directed flange 31 which, when the yoke 28 is swung inwardly of the frame 25 contacts with the end portion of the panel P remote from the member 27. When the yoke 28 is in this position it is held thereat by tighteningthe clamping bolts 29. When it is desired to remove the 10 panel P for any cause, it is only necessary to loosen the bolts 29" and swing'the yoke 28 V outwardly. With the yoke 28 in this position a new panel'P can be readily applied.

As is particularly illustrated in Figs. 6 106 and 7, I disclose a modified form of frame for use in connection with my, improved window, and wherein the bottom portion is partially cut away so that the lower portionof the frame will afiord no obstruction 110 acrosslthe cab door. In theformi of invention as disclosed in Fig.1 6 the frame F substantially rectangular in form with its lower longitudinal member a" cutaway throu, ;houtv its major portion so that when the frame overlies the door or. more pan ticularly the panel thereof untilthe upper horizontal a will obstruct the vision, The members a and 0 together with the end members 7) of theiframe have their: outer margins defined by the inwardly. directed flanges 26. The inner member 6 isadapted to be suitably-attached to the rock shaft R and enacting with said connected end portion of the frame F is a yoke 28: of substantially the same construction and operating in substantially the same manner as the yoke 28 hereinbefore referredto. Secured to the outer member 6 isaimember 27 substantially U-shaped in cross section and otherwise simila' in. construction to the member 27 hereinbefore referred to.

From the foregoing description, it is thought to be obvious that a safety Window for locomotive cabs constructed in accord ance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit there of, and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim:

1. In combination with a locomotive cab having a hinged door at the front and one ide thereof, said door being provided with a window opening, and a window supported for swinging movement in substantially a horizontal plane and coacting with the window opening in the door, said window and door having swinging movement in reverse directions.
