MOTOR-HANGER FOR ELECTRlCALLY-PROPELLED CARS.

SPECIFICATION forming part of Letters Patent No. 555,529, dated March 3, 1896. Application filed June 11,1895. Serialll'o. 552,381. (remodels To all whom it may concern:

Be it known that I, EDGAR PEOKHAM, a citizen of the United States,and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Motor-Hangers for Electrically-Propelled Cars, of which the following is a specification.

This invention relates to means for supporting electric motors on the trucks of electrically-propelled cars.

The object of the invention is to provide simple and efficient appliances for suspending an electric motor on a car-truck in a manner best adapted to distribute the weight of the motor over the truck structure and thereby prevent injurious strains to the truck-frame and its axles, while at the same time the motor is sustained in a desirable position and its vibration materially prevented.

Heretofore electric motors for car-trucks have generally been supported by pivoting one of the ends of the motor on the truckaxle and sustaining the free end or nose of the motor on a spring-equipped hanger supported by the truck-frame, or in cases where the suspending appliances were connected to the sides of the motor such appliances have been supported on the truck-frame only in advance of the motor, and have not extended both in advance of the motor and at the rear thereof. Such suspending means have not served to the best advantage to maintain the motor in its proper relation to the truck-frame and exempt it from the injurious motions of the car-body and axles.

By my invention I aim to overcome the above-mentioned disadvantages, and as I relieve the axle upon which the motor is pivoted of the major part of the weight of the motor the strain upon the axle is consequently greatly diminished.

To enable others to understand and make use of my invention, I have illustrated the same in the accompanying drawings and described it hereinafter, and in claims at the end hereof I have pointed out the features of novelty for which'I desire protection.

In the drawings, wherein like parts are indicated by like numerals of reference in the several views, Figure 1 is a ground plan of a truck to which my invention is applied. Fig. 2 is a longitudinal vertical section on the line 2 2 of Fig.1; and Fig. 3 is a vertical crosssection on the line 3 of Fig. 1, looking to the left.

Referring to the drawings, 4 indicates the upper chord of a truck-frame of the usual construction.

In Figs. 2 and 3 the chord at has been omitted, and in none of the views is there intended to be shown any particular construction of truckframe, and only such parts of a truck-frame are illustrated in the drawings as arenecessary to illu strate the application of my motorhanging appliances.

The numeral 5 indicates the yokes, which are supported upon the axle-boxes as usual; 6, duplex longitudinalbeams extending between the yokes, and 7 similar beams at the ends of the truck and extending from the yokes. The axles of the truck are marked 8 and the wheels 9.

The motor is indicated at 10, and at one end is pivoted in bearings on the axle S in the usual manner, its opposite or free end extending toward the longitudinal center of the truck. At the sides of the motor there are lugs 11 adapted to co-operate with the hangers 12, which are provided with holes into which the lugs enter, as shown. The hangers 12 are connected at their inner ends to the metallic cross-beams 13, which beams are in a plane below the axles of the truck and have their central portions placed edgewise, while near their ends they are turned upward and so deflected as to extend outside of the wheels horizontally beneath rubber bolsters 14, with the fiat surfaces of the ends of said crossbeams resting against the under sides of said rubber bolsters.

The requisite elasticity is given to the inner ends of the hangers by the means whereby said cross-beams 13 are connected to the truck-frame, the said rubber bolster 14 being an element of such means, and the other elements being the shoes 15, spiral springs 16, washers 1'7, and vertical bolts 18. The shoes 15 are adapted to serve as seats for the spiral springs 16, and the vertical bolts 18, surrounded by the coils of said springs, extend a downward through the shoes 15 and between the members of the duplex beams G,which support said shoes, and through the rubber bolsters 14,placed in contact with the under edges of the duplex beams (l. The springs 16 are arranged between the shoes and the washers 17 at the upper ends of the vertical bolts 18. The bolts 18 at theirlower ends pass through the fiat or horizontal ends of the cross-beams 13, and at the ends are provided with heads 19, while at their upper ends are attached nuts 20. It will be seen that by screwing said nuts 20 up and down the elastic tension of springs 16 and of bolsters 14, under which the cross-bcams 13 are suspended from the truck-frame, may be regulated at will.

At the ends of the truck-frame there are placed the transverse beams 21, which are arranged ed gwisc throughout their central portion only, their ends being so twisted as to have their flat surfaces on a plane at right angles to the flat surface of the central portion, the said flat ends resting on top of the horizonal end beams 7, as may be understood from Figs. 1 and The motor-hangers 12, a pair for each motor, are supported at their outer ends from the transverse beams 21, theirinner ends being connected, as explained, to the transverse beams 13. The motor-hangers 12 are of a slightly-depressed configuration, so as to pass beneath the axles S of the truck and are connected at their outer ends to the transverse beams 21 by straps 22, which are secured to said beams 21 by bolts 23, as shown, the said outer ends of the motor-hangers being attached to the straps 22 by the bolts 21h. The

- inner ends of the motor-hangers 12 are connected to the transverse beams 13, which occupy a plane below the axles of the truck, by means of the brackets 25, the said inner ends of the motor-hangers being secured to said brackets 25 bybolts 26, and the brackets be ing attached to the beams 13 by rivets 27.

The connection of the motor 10 with the motor-hangers 12 is near the inner ends of said motor-hangers, and such connection is made by the holes or eyes 28 in said hangers receiving the lugs 11 at the sides of the motor. The bearings on the motor which engage with the axle of the truck are indicated by 29, and this connection, with that of the lugs 11 on the sides of the motor resting in the eyes or holes of the motor-hangers 12, constitute the means of attachment of the motor to the truck and to its suspending appliances.

By the above-described construction I provide an eflicient means of suspending the motor 011 the truck, which is free from complications, and whereby the pivotal connections of the motor to the truck and of the motor to the suspending appliances are all in the same direction, thus avoiding injurious strains on such connections, the suspension of the crossbeams 13 under elastic tension, as herein shown and described, effectually protecting the motors against sudden shocks to which the truck-frame may be subjected.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination with an electric motor pivotally connected at one end to the axle of the truck, of longitudinal motor-hangers pivotally connected between their ends to the sides of the motor and supported at each end from the frame of the truck, substantially as set forth.

2. The combination with a ear-truck haw ing longitudinal side beams, of transverse beams one connected to said side beams at the rear and the other in advance of the axle of the truck, an electric motor pivotal] y connected at one end to the truck-axle and longitudinal hangers extending between said transverse beams and in engagement with the sides of the motor to support the same, substantially as set forth.

3. The combination with a car-truck having longitudinal side beams, of trai'lsverse beams on both sides of the axle of the truck, an electric motor pivotally connected at one end to the axle of the truck, longitudinal hangers having their outer ends connected to one of said transverse beams and their inner ends connected to the other of said transverse beams and elastic connections between the last-named transverse beam and the truckframe, the said hangers pivotally connected to the sides of the electric motor, substantially as set forth.

4. The combination with a car-truck having longitudinal side beams, of a transverse end beam, a second transverse beam elastically supported from the truck-frame near the loi'igitudinal center thereof and depressed motordiangers supported by the transverse beams and pivotally connected to the motor in a plane beneath the car-axle, substantially as set forth.

5. The combination with a car-truck having longitudinal side beams and an electric motor pivotally connected to the truck-axle and provided with side lugs, as 11, of transverse beam 21, a second transverse beam 13 elastically connected to the side beams of the truck, a pair of motor-hangers 12 supported at one end from transverse beam 21, brackets 25 bolted to transverse beam 18 and supporting the opposite ends of said motor-hangers which latter are pivotally connected to the side lugs of the electric motor, substantially as set forth.
