SPECIFICATION forming part of Letters Patent No. 499,321, dated June 13, 1893.

Application filed January 26, 1893- Serial No.459,889. (No model.)

To a/ZZ whom it may concern:

Be it known that I, SAMUEL W. GEAR, a citizen of the United States, residing at Buffalo,

in the county of Erie, in the State of New York, have invented an Improved System of Propelling Canal-Boats by Electricity, of which the following isa specification, reference being had to the accompanying drawings.

My invention relates to an improved system of propelling canal-boats by electricity, which system is fully described and the means for carrying it into practical effect illustrated in the following specification and the accompanying drawings,-the novel features thereof being specilied in the claims annexed to the said specification.

ln the accompanying drawings representing my improved system of canal-boat propulsion-Figure 1 is a side elevation showing two canal-boats proceeding in opposite directions. Fig. 2 is a plan view, showing two canal-boats proceeding in opposite directions, and also a fast boat passing a slower one. Fig. 3 is a transverse section of the canal or waterway.` Fig. Ll is a side View of one of the travelers on one of the guy-wires, showingits lateral motion thereon. Fig. 5 is a side-,view of the same, taken at right angles to Fig. 4.

Fig. 6 represents thetrolley-mechanism in` elevation. Fig. 7 is a side View of the same. Fig. 8 is a side view of the trolley arm, partially in section. trolley arm, taken at right angles to Fig. 8. Fig. 10 is a side view of a modified form of the trolley-arm. Fig. l1 represents a modified form of the trolley-standards. Fig. 12 is a side View of the springs at the upper ends of the trolley-standards.

My improved system of propelling canalboats by electricity comprises a suitable generating station, a laterally adjustable conductor arranged over the waterway, and suitable trolley-mechanism on the boat by which the current is conducted to the motor which operates the propeller.

My system also contemplates the use ofa laterally adjustable return wire, and suitable connections, by which the current after having passed through the motor, is conducted back to the generator. In order to provide for propelling boats in both'directions, two

Fig. 9 is a side view of the power wires are employed, and also two return wires, if desired. A third power wire is arranged between the others, for certain purposes hereinafter described,such as to enable a fast boat to pass a slower boat going in the same direction. The power and return wires are supported on guy-wires in such fashion that they can travel laterally to conform automatically to any lateral motion ot' the boats. The trolley mechanism is also preferably made in some 'part self-adjusting in the lateral direction.

My invention also comprises various other arrangements and details of construction, all as hereinafter more fully described.

In the accompanying drawings representing the manner of carrying my improved system of canal-boat propulsion into practical effect, C represents the canal or waterway, B B B2 canal-boats, G the transverse guy-wires, P P P2 the power wires,andRR the return- Wires.

A represents a power house, in which is located a suitable electric-generator, E, which may be operated by steam or water, which may be taken from the canal itself.

The guy-wires G are arranged across the canal at suitable distances apart,-being supported by posts D D or other structures on the banks of the canal. Provision is made for maintaining suitable tension on the guywires by a turn-buckle or a threaded rod ar ranged in any preferred manner.

F, Fig. 2, represents the tow-path and J the bank on the opposite side of the canal.

The power wires P P', P2 receive the current from the generator E through a suitable conductor, as represented at b, Fig.'2, and the return wires are connected to the opposite pole of the dynamo through a conductor c. The canal or waterway isdivided into sections of suitable or convenient 1ength,-each section being provided with its generating station and system of conductors. The generating station may be located at one end of or at any convenient point near the section supplied by it. The power wires are preferably arranged so that the same trolley comes Y in contact with the power wire, whether the boat is proceeding in one direction or the other. Thus in Figs. 2 and 3, the power wires IOO P P2 are located on the outside, and the re turn wires R R on the inside, with the auxiliary power wire P in the center between the return wires. The right-hand trolley c, consequently receives the electricity from the power wire P when the boat is moving in one direct-ion, and from the wire P2 when the boat is proceeding in the opposite direction. The other trolley o conducts the current to the return-wires.

The travelers or mechanism by which the conducting wires are supported on the guy wires so as to be laterally adjustable thereon, to adapt themselves to the lateral movements of the boatcaused by the steering or drifting, will be understood from an examination of Figs. 4 and 5. The travelerTconsists of one or more grooved pulleys which run on the guide-wire, a suitable frame, and an insulating device which carries the conductors. In the accompanying drawings the traveler is represented as provided with three pulleys, d d cZ2,-two on the upper side of the guy-wires, while t-he third is placed below the wire. The frame e c' is arranged on each side of the pulleys and is provided at its lower part with a socket or other suitable device for receivingY an insulator or insulating block. In the construction shown, the frame is given in the shape of a socket, f, which incloses a perforated insulator g. The conducting wire P is fastened to a clip h, having a stem/L' which passes through the insulator and is provided with a nut or other suitable device at its upper end to hold it in place therein. The insulator is provided with a peripheral groove, into which a flange on the interior of the socket projects, to hold the insulator in place. The socket is divided,-onehalf of it being formed on each side-frame e c,-the parts being secured together by bolts or other suitable devices. The frames e c are secured together by the bolts or studs j j, on which the pulleys revolve. Below the guy-wire, the frames are joined, as represented at 7c, to prevent the pulleys from getting ott the wire. Any other suitable form of traveleror insulator may however be employed. All of the conducting wires are supported on the guywires by similar travelers. Sufficient slack is left in the conductors b and c, to permit the lateral movements of the conducting wires.

In order to prevent the conducting wires from approaching too close to each other, the travelers are provided with projecting arms or bniicrs,Z Z', which come in contact with each other, as represented on the right hand in Fig. 4, so that the conducting wires are always maintained at the proper distance apart, although permitted to shift laterally on the guy-wires to adapt themselves to the lateral movements of the boat. These buffers are made in any convenient way, being shown in the drawings as formed of loops secured at their ends by the heads and nuts on the bolts of the pulleys CZ tl.

The trolley mechanism consists essentially of two pivoted uprights or standards, I-I I-I mounted on the boat near the center of its length, and carrying a. suitable cross-bar I, on which the trolley-arms a, and 0 are supported in such manner that they can shift laterally thereon, as indicated by the dotted lines in Fig. 6. This lateral movement assists the lateral movement of the conducting wires, as the boat pursues its more or less sinuous course. For example, it' the boat B, Figs. 2 and 3, diverges toward the righthand, as indicated at B3 in dotted lines, the return wire R will shift laterally, toward or up to the position indicated by the broken line R52-one or more of the travelers sliding on the guy-wires. The power wire P however will remain straight,-the trolley arm a, sliding inward on the cross-bar I,-unless the deviation of the boat should exceed the distance between the trolley standards II Il', in which case the trolley arm a will slide on the bar I until it comes in contact'with the other arm o, after which, if the deviation continues, the wire P will also be shifted laterally. The lateral movement of the return wire and its trolley-arm are represented at R3 and o', Figs. 2 and 3, when the boat has diverged toward the right. When the boat inclines in the opposite direction, toward the left-hand, the power wire P will be drawn inward by its trolley-arm a, toward the center of the canal,- one or more of the travelers which support this conductor sliding along the guy-Wires, while the trolley-arm oon the return wire R will slide along the bar I until the deviation is equal or nearly equal to the width of the boat,-after which, if the deviation continues, the return wire R will be shifted inward until its traveler comes in contact with the traveler of the central power wire P. The two wires R and P may then be allowed to shift laterally together, but it will be more convenient, when such an excessive deviation occurs, and if it be desired to continue the motion of the boat along the left-hand side of the canal, to connect the trolley arm a with the central power wire P and the trolley arm o with the return wire R. The construction of the trolley mechanism permits this to be effected readily,-thetrolley-arm ct being moved inward so that it comes under the power wire P, as at a', Figs. 2 and 3, and the return wire R being moved inward if necessary until it comes over the trolley arm o. The positions of these parts at this time are represented approximately at R, 02, Figs. and .3. It will be observed that this arrangement will enable a fast boat, B2, to pass a boat, B, going in the same direction at a slower rate of speed. At B2, Fig. 2, I have represented a boat passing a slower boat B .-the power to propel the boat B2 being derived from the central power wire P, while the return is effected through the return wire R. At B4 the boat B2 has completed its movement from one side of the canal to, the other, and is proceeding to pass the boat in a parallel path, after which it will IOO again return to the proper side of the waterway.

The current is brought from the trolley arms to the motor M by suitable insulated conductors la k2. The motor is arranged in any con` venient location, preferably in the rear part of the boat,-being connected to the screw S so as to operate the same either directly or by suitable intermediate gearing. In order to provide for reversing the motor, so that the boat can be backed, a suitable switch, n, Fig. 2, is introduced between the trolley arms and the motor, by which the direction of the cnrrent through .the machine can be changed. This switch is preferably located near the trolley mechanism, so as to be conveniently under the control of the man who operates the trolley mechanism. The switch also enables the boat to proceed on the wires P2 R in the same direction as on the wires P R, or viceversa,-the trolley arm o in this case receiving the current from the power wire P. It will also enable the boat to proceed or back up on the wires P R. The switch is of any ordinary or preferred construction adapted to the purpose of changing the direction of the current through the motor.

In order tov permit the lateral motion of the conducting wires, it should be understood that a slight amount of slack is left in them,-a sag of eighteen inches in one hundred and fifty feet allowing a traveler to move laterally about seven and a half-feet on a length of wire of three hundred feet,-the guy-wires being .placed one hundred and fifty feet apart.

Separate guy-wires may be employed for the power and the return wires-the insulation being introduced in the guy-wires. The conducting wires may be fed at different points along the length of a section by suitable conductors.

Any suitable variable resistance may be employed to vary the strength of the current supplied to the motor.

The trolley-mechanism is constructed in such manner as to permit the trolley pulleys to be shifted laterally transversely of the boat, and also to maintain the proper electrical connection with the conducting wires. To effect these results the trolley mechanism may be constructed in various different ways. In the drawings I have represented the trolleyarms a and o, which carry the grooved pulleys fr which make contact with the conducting wires, as carried by a transverse bar I, supported by the pivoted standards H H', but under certain circumstances, such as when a boat steers accurately, the trolley-pulleys may be supported on independent hinged standards,-the lateral movements of the conducting wires being sufficient to compensate for the lateral deviations of the boat from a stright line. Askillful-steersman under such circumstances can perform the necessary operations of guiding the boat so as to'avoid contact with the banks, to turn out on meeting boats, or, if necessary, to pass a slower boat,-availing himself only of the lateral adjustabilty of the conducting wires. These operations may also be facilitated, when using a single standard for each trolley-pulley, by lengthening the shaft on which the pulley runs, so that it may adjust itself laterally as indicated in Fig. ll. But for ordinary purposes, it is found most satisfactory to employ the double standards and cross-bar carrying the trolley-arms as represented in Figs. 3 and 6. The standards are constructed conveniently of a light frame work, of any suitable material. If made of metal, they may consist of the bars p p', withthe bracing @1,- the standards being pivoted on the rod s supported by the base w. A spring o', Fig. 7, connected to the lower end of the standard and to the base, serves to keep the trolley pulley in contact with the lower sides of the conducting wires. The standards w are secured to the deck of the boat, on opposite sides thereof, near the middle of its length,- it being preferable to have the trolleys make contact with the wires as near the center of the length of the boat, as possible. At their upper ends, the standards support the crossbar I, which carries the trolley arms a and o, and is preferably triangular or square in shape. The cross-bar may be rigidly secured to the upper ends of the standards, or pro- Y vision may be made at these points for acertain amount of yielding in the bar. In the construction shown, the bar I is represented as supported on the upper ends of the standards by the springs ca -one of which is shown detached in side elevation in Fig. 12. These springs are fastened to the upper ends of the standards by bolts or other suitablev devices, and at their upper' ends, they receive the cross-bar I in openings of suitable shape,-provision being made to prevent endplay in the bar by collars or in any other suitable way. These springs support the bar in a manner that permits it to yield to comtween the socket b and the arm X which car-v ries the trolley-pulley r. In the construction shown, this insulator consists ofthe blocks g g2, of any suitable insulating material, inclosed in a socket V and secured in place by a screw-ring or other suitable device t. A stem h2 on the socket b extends into the split insulator g g2,-its upper end being enlarged to fit a correspondingly shaped recess in the insulator. Any other suitable arrangement may be adopted.

IIO

In a modified form of the trolley arm, represented in Fig. l0, the requisite yielding motion is provided for by attaching the arm to the bar I so that it can swing thereon. In this case the socket is made round, and cone sists of two parts, b2 and c2, held together the sunken screws c2. The arm X is supported r on the insulated stem Z1,2 projecting outward from the sleeve V which is fitted on the socket 11202 so as to turn freely thereon. The arm is attached to the socket by the spring U, fastened at one end to the stem 71.2 at i2, and at the other end at ,i2 tothe socket. This spring permits a certain amount of yielding motion in the arm and pulley, so that the latter is maintained all the time in contact with the conducting wire. Provision is made for preventing lateral motion of the sleeve on the socket in any suitable way,such as a pin inserted in the socket through a slot in the sleeve, which will also act as a stop to limit the movement of the arm.

In order to prevent any accidental contact between the conducting wires and the crossbar, I supporta guard .e over the trolley mechauism by means of the arms Z2 Z3, attached to the standards. This guard may be made of or coated with insulating material, or is supported in insulated sockets u n2 on the arms Z2 Z3. The guard may be formed of an iron rod coated with porcelain or other insulating material.
