ELECTRIC RAILWAY.

Specification of Letters Patent. Application filed May 19, 1905. Serial No. 261,208.

Patented May 1, 1906.

T0 all 'wh/0m, it may concern:

Be it known that 1, MATHrAs A. LAZAREFF, a resident of the city, county, and State of New York, have invented a new and Imroved Electric Railway, of which the folowing is a full, clear, and exact description.v

n My invention relates to im rovements in electric railways, and-especia y to the construction which is adapted for use as a surface or elevated structure or in a subway, as distinguished from the conduit or overhead trolley systems. A,

The object of my invention is to produce a simple and practical electric railway in which the main conductor, is absolutely housed in, so that no one is likely to be injured by coming in contact with it and so as to prevent the conductor from being interferred with by rain, snow, ice, dirt, or other obstructions.

My invention is also intended to construct a housing which will permit a collecting-shoe of any suitable design to be used and in. which the housing will be normally dead, but will have a conductive surface which is automatically cut in and out of circuit as a train prpgresses.

ith these ends in view my invention consists of certain features of construction and combinations of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming figures of reference indicate corresponding partsin all the views.

Figure 1 is a broken side elevation of my improved construction. Fig. 2 is a crosssection with the contact-strip of the housing in circuit. Fig. 3 is a section similar to Fig. 2, but with the contact-strip out of circuit. Fig. 4 is a broken sectional plan of my invention, and Fig. 5 is adiagrammatic section, showing how the invention can be applied to a curve.

My invention comprises a housing which is preferably of generally rectangular shape, and this can be made of any suitable material, though wood can be used to advantage in the greater part of its make-up. lt comprises a back 10, a t'op v11, and a front 12, this latter part also by a contact-strip sections insulated from each other, as shown a part of this specificaat 14-that is to say, the Contact part 13 is preferably made up in such sections, and if the housing is of conductive material the insulation will of course be carried all around it. No novelty is claimed for this feature,

however.

Projecting from the upper part of the housing is a guard 15, which extends outward, so as to shield the contact-strip 13 and prevent it from being touched easily or from having anything come into contact with it excepting the collecting-shoe. The whole structure rests on a suitable sleeper or support 16.

Within the housing and extending longitudinally thereof is a conductor 17 for carrying the electricity, and this may be of any approved form, and it rests on a suitable insuation 18.' Rising from the conductor at necessary intervals are posts 19, which carry switch-arms or contact-arms 20, these being preferably, though not necessarily,in pairs, as shown, so that they will make a good connection with the contacts 21, which are carried by a hub 22 .on the shaft 23, and extend radially from the shaft, so as to pass between the switch-arms 20. It will be understood that while this structure 2() .and 21 is preferred it is not absolutely essential,`and any equivalent structure can be used which by the rotation of the shaft will bring the stationary and movable contacts in touch..

The shaft 23 extends longitudinally of the housing and where a curve occurs the shaft may be made up of sections 23a, connected by universal joints 23h, or instead of this the ordinary flexible shaft or any well-known similar contrivance can be used, it beingjunderstood that I do not claim the shaft except in combination. The shaft is. supported on brackets 23", which extend inward from the part 13 and serve the double purpose of supporting the shaft and also carrying current to the contact-strip. The current is also carried bythe contact slide-bars 27, to be hereinafter referred to. Each shaft-section 23 is provided, near its ends, with ratchet-wheels 24, which are engaged by a dog 25, which is pivoted, as shown at 26, on the slide rod or bar 27, and the latter is adapted to project at one end through a hole 13aL (see Fig. 4) in the contact-strip 13, this protruding end being preferably rounded, as shown at 27 a so that IOO ' and when the it may make easy contact with the shoe 28. The contact slide or bar 27 moves in a suitable guideway 27h. The collecting-shoe 28 is adapted to extend beneath the guard 15, so as to Contact with the strip 18, and it can be of any approved construction. When the slide rod or bar 27 is pushed inward, 'it causes the ratchet-wheel 24 to be turned a distance of one tooth, thus turning the shaft 23 and bringing the contacts 21 into engagement with the contacts 20, as in Fig. 2, and so the current passes through the said contacts, the Shaft 23, the bracket 230, and also through the ratchet-wheel 24, the pawl 25, and the rod 27 to the contact-strip 13. The inward movement of the next slide -rod and pawl turns the ratchet-wheel another tooth and brings the contacts 20 and 21 out of touch, as in Fig. 2. The slide rod or bar 27 can be vreturned to its first position after being pushed inward by the shoe by a spring or any suitable mechanism, but I prefer to use a weighted arm 29, as being more reliable, and this arm is pivoted, as shown at 30, and has a dog 31, extending into the path of the slide rod or vbar 27. When the slide-rod is pushed in, the weighted lever is swung inward, as in Fig. 2, shoe 28 passes the end of the slide-rod the weighted arm swings back and causes the slide-rod to be returned.

It will be seen that as the train moves `along the shoe 28 of a car or a train, as the Case may be, will push in the slide-rod 27, so as to energize the contact-strip 13 beneath the train, so that the collecting-shoe can pick up the current as usual, and' when it strikes the neXt slide-rod it turns the shaft another step, as described, cutting out the current, and so by having the slide-rods and ratchet mechanism in pairs a single shoe serves to collect the current and cut it in and out of the contact-surface of the housing.

From the foregoing description it will be seen that I provide a very simple and practical means of covering the live conductor, so that the housing is normally dead, and that I also provide an efficient means of cutting the contact-strip 13 of the housing in and out of circuit. It will be understood, too, that many of the details of this structure can be departed from without affecting the principle of `the invention.

Having thus fully described my invention,
