RAILWAY APPLIANCE.

SPECIFICATION forming part of Letters Patent No. 492,598, dated February 28, 1893. Application iled September 9, 1892. Serial No. 445,465. (No model.)

To a/ZZ whom it may concern:

Beit known that I, JAMES WAYLAND, a citizen of the United States, residing at Newark, in the county of Essex and State ot New Jersey, have invented certain new and useful Improvements in Railway Appliances; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to letters and iigures of reference marked thereon, which form a part of this specification.

This invention relates to certain improvements in that class of railway appliances described in my contemporaneous application filed January 2l, 1892, Serial No. 418,793, the object of the invent-ion being to secure greater reliability of action under the heavy strain imposed by the passing trains, to secure greater durability in the construction of parts, and greater simplicity and cheapness, and to more perfectly avoid, in the operation of the semaphore, the shocks or jars by ywhich the more delicate parts are broken or disarranged and the signal thus rendered less exact in its indications, and to secure other advantages and results some of which will be referred to in connection with the descriptions of the working parts.

The invention consists in the improved railway appliances and in the arrangements and combinations of parts, all substantially as will be hereinafter set forth and finally embodied in the clauses" of the claim.

Referring to the accompanying drawings in which like letters and numerals indicate corresponding parts in each of the several figures, Figure l is a vertical'section taken at right angles with a railway rail through certain of my improved signaling appliances and showing the general relation of the several parts. Fig. la is a detail of a certain rod showing the adjustable relation of one part with the other. Fig. 2 illustrates one construction ot' aspring for returning the devices to aninitial or normal position after the train has passed from the block. Fig. 3 is an enlarged view of a (at present) preferred construction of the returning spring and co-operating mechanisms. Fig. 4 is a sectional detail taken on line Fig. 5. Fig. 5 is a side elevation in detail of a tread-lever by means of which the power of the passing train is utilized in operating the signal or other appliances. Fig. b' is a-detail plan of said tread in connection with the spring, 85o., shown in Figs. l and 2. Fig. 7is a detail view of a spring arranged in connection with the tread-lever for raising the latter when released. Fig. 8 is an enlarged detailr showing certain of the mechanisms at the base of the standard or support for the signal or other device to be operated, the view being taken from the direction of the track and Figs. 9 and lO are views showing the mechanisms in the normal position or position to receive the train, and abnormal position assumed immediately after the passing of the train from the block respectively, the views being taken in directions parallel with the track.

In said drawings, a indicates a railway rail, b a semaphore post or standard upon which the signal or appliance to be operated is stationed, c indicates said semaphore.

Upon the outer side of the track a, and extending substantially parallel therewith is arranged a tread-lever lo, Figs. l and 5, one end of which is formed on anincline and projects above the track so that, on the passingof the train, the wheel will press the lever down with an easy movement. The said lever is fulcrumed, as shown in Fig. 4, upona bracket, Z, of peculiar construction, the said lever being pivoted upon the bolt, fm., of said bracket so as to work in a vertical plane. The said bracket consists of a horizontal plate, Z, which extends beneath the bottom flange of the rail and bears up against the same, a vertical portion, Z2, which provides bearings for the pivotal bolt, fm, and is provided with a stay projection, Z3, which overlaps one side or edge of the rail liange, and a bolt, Z4, having a head,

Z5, which overlaps the opposite edge of the 95 rail flange, the parts Z3, Z5, cooperating in holding the bracket to the rail. The bolt, Z4, is

backed and braced by an upward projection, i Z6, of the horizontal plate. At aboutthe center of the lever, the same is provided with an LJI incline or wedge-shaped projection, n, Figs. l and 5, to engage a plunger p and give horizontal movement to the same in a direction away from the rail. The said plunger is suitably supported in bearings admitting of horizontal movement. In the construction shown in Figs. l, 2, and 6, the plunger is carried at one end by the spring, o, which in this case is carried by a downwardly extending frame, o', secured to the rail, which said spring serves to return the plunger to its normal position,but in thepreferred construction,shown in Fig. 3, the plunger consists of a vertical part, p', and horizontal part, p2, of tubular form, the vertical part being pivoted upon a bracket or frame p3, 20, at a point below the level of the rail and at its upper extremity being provided with'a tongue, p4, upon which the said tubular part, p2, is arranged. The upper extremity of said vertical part is formed on an incline, p5, to receive the inclined or wedged portion of the tread-lever. The end of the tubular portion of the plunger, where it engages the vertical portion, is strengthened by nuts, p6, the face of one of which is curved to allow for the pivotal movement of the vertical portion. On the passing of the train, the tread lever is depressed, so that its upper edge is brought to the level of the railtread, and its inclined portion, n, slides on the incline, p5, of the plunger, the latter being thereby forced outward or away from the rail. Upon the tread-lever is formed a catch, 7c', which, when the tread is forced to its lower limit of movement, is caught bya co-operating catch, p8, of the plunger and thus held in its depressed position until released by the movement of the train from the block. To secure the catching of parts described, I employ the spring, o, which,in the construction of Fig. 3, is an ordinary helical spring arranged on the tubular part of the plunger between adjustable bearings, p9, and a ixed bearing, p10, in oron which the tubularportion slides. When the tread-lever is brought to its lower position as before stated and the catch projection, k', rides under the catch projection p8, the spring, o, operates to force the plunger back toward the rail, but its movement in this direction is only sufficient to cause the two parts to remain in their abvnormal positions, further movement in this direction being prevented by a stop, 7a2, formed above the catch 7a', which stop serves to hold the plunger in position to regulate the co-operating parts more intimately connected with the semaphore or appliance to be operated.

Upon the passing of the train out of the block, the pressure of the spring, 0, is m0- mentarily counterbalanced and the vertical portion is freed from the pressure of the tube, p2, or the nuts, p6, thereon. Immediately a tread spring, q, Figs. 6 and 7, acts to throw the tread-lever upward to its normal position, the inclines, 7c3, p7, serving to facilitate such opelation. This upward movement ot' the tread-lever is limited and controlled bya limiting projection, 7a4, Fig. 7, which extends from said lever toward the rail and engages the under side of its head, as will be understood. By means of this projection, the pressure of the incline, p5, against the incline n, will not throw the tread to such an elevation as to prevent a constant engagement of inclines.

Loosely connected to the plunger, is a rod, r, which is arranged horizontallyin a tube or casing, s', which extends to the semaphore post. Said rod has an independent movement with reference to the plunger, which movement is imparted, at the passing of the train', by the weight, d', of the semaphore or other appliance to be operated. At one end, said rod is provided with a head, r', to engage an abutment, p20, of the plunger, and at the opposite end engages a crank, lever or pulley, s, Figs. l, S, 9, 10, working in bearings, t, at the base of the post or standard. Said rod is connected to the shorter arm of the lever, crank or pulley, while the longer arm is attached, by a flexible connection u, or otherwise, to a vertical rod, fu, extending up the post to a chain or flexible connection, w, which in turn connects with the drum, w', of the weighted semaphore or appliance to be operated.

At the passing of the train over the tread, 7c, and the horizontal movement ofthe plunger away from the track, the weight, d', which overbalances the semaphore blade, or the appliance to be operated, and the connections, including the rod, r, draws the said blade, c, to lthe danger indicating position, and the said rod, r, and its connections, to their abnormal positions preparatory to being drawn to their normal position by the spring, 0, after the passage of the train from the block. To disengage the catches 7c', p8, and allow said spring to act as stated, I have provided catchreleasing devices, controlled by an electric circuit which extends to the farther limit of the block, the said farther limit having stationed thereat, a suitable circuit closer or changer adapted to be operated by the passing train. On this circuit, at the standard or post, b, is an electro-magnet, 2,which is adapted to attract an armature, 3, having a catch, 4t, thereon. Said catch, a, engages a co-operating catch, 5, on aweighted lever, 6, adapted by the force accumulated by the gravitation of the weight to release the catches 7c,p8.

The method preferred of securing the release by the sudden or hammer like action of the falling weight is illustrated in Figs. 8, 9, 10, where the horizontal bar, r,which is preferably in sections adjustable in relation to one another, as shown at 7, Fig. l, is shown to be arranged on pins or bearings, 8 and 9, the pin 8, connecting the crank or lever, s, to the said bar and the pin, 9, being a fixture and serving as a support or guide for the rod or bar, fr, and to secure a regular and steady horizontal movement as desired. The pin, 9, works in the slot, 10, when the upward draft Lovercome the power of the spring o.

of the chain operates the crank or lever s, and rod lr. The pin, 8, works in a short slot, 11, and thus the rod, r, is allowed a limited movement independentof the crank or lever s. The rod, lr', is provided with a bearing 12, preferably at a point between the two pins 8 and 9 and the lever, 6, at the end opposite the weight, 16, thereof is provided with a bearing, 13, to engage the bearing, 12, when the weight has arrived near its lower limit of gravitation.

When the train has passed into the block and the plunger, 10, has released the rod, r, and the weight d', acting through the connections tt, and s, has drawn said rod so that said rod has slid to the position shown in Fig. 10, the lever, 6, being still in the position shown in Fig. 10, in caught relation to the armature catch and the bearing, 12, being in advance of the bearing, 13, of the lever 6, these relations are maintaineduntil the train arrives at the end of the block, when said train closes the circuit changer, the electric circuit mag-V netizes the magnet, 2, and the last attracts its armature, 3, and at the same time releases the catch, 4, from the weight catch 5. The weight 16, immediately gravitates and turns the lever, 6, on its fulcrums 17, and, when it has accumulated considerable force, the bearing, 13, is brought into engagement with the rodbearing, l2, and thus the rod, r, is moved longitudinally backward with sufficient force to This movement releases the catch, p8, of the plunger from the catch la of the tread, k, and the latter is raised by the power of the spring, q, and the spring, o, immediately acts to draw the sliding rod forward toward the track at the same time drawing the semaphore down to its safety indicating position and the weighted lever and its catch, 5, up so that it enters automatically into a caught relation with the armature catch 4, which immediately assumed the position shown in Fig. 10, after the circuit closer referred to was passed by the train. Said circuit closer possesses no feature of novelty in itself or in its relation to the track and post or station b and consequently is not shown.

To provide durable and effective means for holding the plunger, p, and rod, fr, in proper relation to the tread lo and track and one another, and to protect the rod and admit of expansion of the same when subjected to an increase of heat, I have constructed the frame, 20, with bearings, 30, by which it is firmly secured to the bottom ange of the rail and with bearings, 31, to receive the tube, s', which incloses and protects the rod r. Said tube preferably extends th rough the vertical bearing portion 3l, of the frame and is rmly held therein by nuts 2l, 21., on opposite sides of said vertical portion The opposite end of the tube, s', is held in loose bearings in the box, b', or other portion of the standard or post b, and is allowed a movement therein to admit of expansion of the metal. By means of these connections with the rail and standard, firmness and security for the working parts are obtained.
