Application fled January 22, 1921. Serial No. 489,068.

To all whom. it may concern:

Be it known that I, Amsnnr L. JONES 2d,

a citizen of the United States, and residing specification, such as will enable those 8 illed in the art to which it appertains to make and use the same.

' This invention relates to miniature electric railways and the object of the invention is to provide railways of this class with means for stopping the progress of an electric locomotive or car over the track of such railways, said stopping means being preferably in operative connection with asignal' post construction located at a predetermined point along the track of the railway, and with this and other objects in view the invention consists in a stop device of the class and for the purpose s ecified which is simple in construction an operation and eflicient in use, and which is constructed as hereinafter described and claimed.

The invention is full disclosed in the following specification, 0 which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in'each of the views, and in which Figure 1 is a plan view of one section of the track of a miniature electric railway with a signal post construction mounted in connection therewith, and showing my improved stolp device; 1

ig. 2 is a artlal section on the line 2-2 of F1 1 an indicating the use of my improve stop device;

Fig. 3 is' a partial section on the line 33 of Fig. 1 with part of the construction broken away;

Fig. 4 is a view similar to Fig. 3 but showin parts in a different position; and,

1g. 5 a partial section on the line 5-5 of I Fig. 1 and on an enlarged scale.

on three transverse ties 14, the rail 13 beinginsulated from the'tie 14 as shown at 15.

The construction of the rail section 10 forms no art of my invention and is merely shown to illustrate one use of my improved stop device for railway systems of the class specified.

I preferablymount in connection with the section 10 a base 16 u on which a part of the rails 11 and 13 are a apted to rest as shown 1n Figs. 3 and 4, and mounted on the base 161s thestandard 17 of a semaphore, the signal arm 18 of which is pivoted to said standard as shown at 19, and said arm carries red and green translucent panels 20 and 21. Pivote to the. base 16'at one side of the standard 17 is an approximately triangular plate 22 to one corner ortion of which is pivoted a rod 23 whic with the signal arm 18, as clearl Figs. 3 and 4 of the drawing. Th

shown in e trianguis also connected lar plate 22 is provided with a backwardly directed finger piece 24 which forms means by which the switch arm may be raised and lowered in the usual manner.

I also mount in connection with the plate 22 a forwardly directed rod 25 which passes downwardly through an aperture 26 1n the base 16 and then forwardly in a cut-out portion 27 in'said base, and is connected with a lever 28 mounted in the cut-out portion 27 and p voted to the base as indicated at 29' in Fig. 1 of the drawing.

practice, I also mount in connection.

with one of the rails 11, 12 or 13, preferably the rail 13, a supplemental rail 30 composed of insulated material, and the rail 30 is mounted in connection with the rail 13 by bolts or rivets 31 passed through said rails, said bolts or rivets passing throu h elonated inclined apertures 32, as clear y shown in Fig. 2 of the drawing, whereby in the movement of the supplemental rail 30, as

hereinafter described, said rail will be raised and lowered.

The rail 30 is placed in operative connection with the'signal post construction b the means for operating the signal arm 18' t ereof through a rod 33 pivoted to the lever 28 and pivoted approximately centrally of the rail 30, as indicated at 34. The rod 33, in the form of construction shown, extends outwardly through the cut-out portion 27 of the base 16 upwardly over one of the ties 14 and downwardly and transversely the rails 13 and 30, as shown at 35 in Fig. 5 of the drawin One end portion of the rail 30 is preferab y beveled to a slight extent as shown at 36 in Fig. 2 of the drawing.

I am well aware of the fact that signal post constructions involving standards 17 and signal arms 18 as well as the means for operatin manly employed in connection with electric railways of the class under consideration, but no means have been provided for sto ping a locomotive as it approaches a sema ore or signal post construction, the signa arm or element of which is set at danger, and with my improved supplemental rail which is mounted in connection with the central rail 13 of the'track, a locomotive or car approaching a signal post construction, the signal arm or element of which is set at danger, may be stop ed, and said locomotive or car automatlcally started by simfly moving the signal arm or element out o danger position, or into position to indicate a clear track.

The above result is accomplished in the following manner. In Fig. 3 of the drawing I have shown a signal arm 18 of a slgnal post construction in a position which indicates a clear track and in this position it will be noted that the rail 30, or the top face thereof, is located below the top face of the rail 13 so that an electric locomotive or car, part of which is indicated at 37 in Figs. 3 and 4 of the drawing, or the electric contact rollers 38 thereof, w1ll readil pass over the track section 10 and by the signal post construction which is in the position shown in said fi' re.

In 4 of the drawing, I have shown a signal arm 18 of the signal post construction and various other parts in a different osi tion from that shown in Fig. 3, and in w ich the signal arm 18 is set at danger and the rail 30 of the top face thereof projects be' yond the top face of the rail 13 so that when the locomotive or car 37 approaches the track section 10, the contact rollers 38thereof will pass upwardly over the beveled end portion 36 of said. rail and thus onto the top face thereof, in which position the said contact rollers are out of electrical communication with the rail 13 and the circuit to the electric motor of said locomotive is broken.

The two different ositions of the rail 30 and rollers 38 are a so shown in full and dotted lines in Fi 2 of the drawing; It will be apparent t at the movement of the various parts of the post construction, in-

I cludin-g the-rail 30 from the position shown in Fig. 3 to that shown in F1 4 is accomplished by raising the finger piece 24 of the trian ular plate 22, and by again depressing this nger piece the parts may be returned to the position shown 1n Fi 3, and if a locomotive or car be stoppe in the manner said arms are old and have been com-- above set out, or by raising the rail 30, it will be seen that'saidlocomotive or car may be again started by simply returning the parts to the position shown in Fi 3 and shown in full lines in Fig. 2, in wiich operation the contact rollers 38 are again brought into engagement with the rail 13.

It will also be seen that the rail 30 in add 1t1on to acting as means for breaking the c1rcuit through the contact rollers 38 and rail 13 will also act in the manner of a brake tomore quickly stop a locomotive or car approachmg a signal post construction set at danger.

It will be understood that while I have shown certain details of construction for carrylng'lmy invention into eifect and have shown t e stop device employed in connection with a semaphore that I am not necessarily limited to these specific uses, and vari'ous other. changes in and modifications of the construction herein shown and described may be made, within the scope of the appended claims, without departing from the what I c aim asnew and desire Letters Patent, is
