GENERATOR SUSPENSION.

memes.

To all whom it may concern Be it known that 1, ROBERT M. DIXON, a

citizen of the United States, residing at East Orange, in the'county of Essex and State of New Jersey, have mvented certain new and useful Improvements in Generator Suspension, of which the following is a full, clear, and exact description, such as will enable other skilled in the art to which it appertainsto make and use the same.

This invention relates to the mounting of generators to be driven from car-axles.

. One of the objects of the invention is to provide a practical and eificient device of the character described in which the parts are readily assembled and securely held in position and are adapted to give an even and reliable drive to the generator;

Another object of the invention is to provide a device of the character described which shall be compact, cheap, and simple in construction, and readily adjustable to meet various conditions of use.

Other objects will be in part obvious and in part pointedout hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which Will be indicated in the following claims.

In the accompanying drawings, wherein is shown one of various possible embodiments' of the invention, Figure 1 represents a plan View of the invention in connection with a car-truck. Fi 2 represents a side elevation thereof; an Fig- 3 represents a rear end elevation thereof.

The device, as shown in the drawings, is preferably attached to a car-truck Which may be of any standard type. Generally speaking, the arrangement of parts as shown in the drawings is as follows: A truck sup ports a. fixed frame, which in turn supports a sliding frame or carriage upon which is mounted a dynamo. adapted to be driven through suitable connections by an a'xleof the car-truck.

The fixed frame consists of projecting arms 1, preferably attached to the side sills 2 of the truck, and cross-bar 3. The crossbar occupies a position below the arms and its extremities are curved upwardly to meet th a jms, towhich they are preferably riv- Specification of Letters Patent.

eted. The sliding carriage, moun pro ecting arms, comprises a pair of side bars l each of the side bars being adapted to bear throughout its length and to slide on one of the projecting arms. It also includes a pair of parallel depending members each of which comprises a. pair of hanger links 5 situated on opposite sides of the frame and a cross-rod 6 attached at the lower portion of these hanger links. Each of the links is pivotally attached bya bolt 7 to one of the side bars at a point preferably above the projecting arms. Each cross= rod 6 passes through the oppositely disposed hanger links 5 and its ends are threaded and are secured to the hanger links by nuts 8. The cross-rods may be removedfrom the hanger links by unfastening these nuts. The motion of the side-bars is guided by means of plates 9 attached upon either side thereof and extending downward in such position that they straddle each of the arms.

As shown in Fig. 1, each of the hanger links consists of two upright bars which are riveted together in such manner that 'a space is provided therebetween, and through this space'the projecting arms pass. It will be noted that any lateral thrust given to the carriage will be substantially compensated by contact of the bars of the hanger links with the projecting arms.

The projecting arms are braced to withstand vertical as Well as lateral movement by means of diagonal braces 10 attached to the end sill 11 of the car-truckQ As will be noted, the braces are rigidly attached to the end-sill and are so secured to the movable carriage that the'latter may be moved longitudinally with respect to the arms. This longitudinal movement is permitted by slots 12 formed in the guide plates 9, through which pass bolts 13 adapted to retain the carriage at any desired position with respect to the brace. The carriage is additionally secured by bolts 14: associated with slots 15, also adapted to permit longitudinal movement of the carriage.

Mounted upon the lower cross-rods 6 is the dynamo 16 Whichis adjustable laterally and horizontally as hereinafter described. The dynamo is provided with lateral lugs 17 through which the cross-rods pass. The lugs are adaptedto loosely support the dynamo so that it may rotate about the rods and thus maintain a substantially level poaao 8 on b 6 sition. Between each pair of lugs a collar 18 is placed which is rigidly secured to the cross-rods by bolts 19 and serves to hold the dynamo in a desired position. In order to laterally adjust the dynamo the collars are loosened and the dynamo may then be moved along the cross-rods into a given position.

I side of the cross-bar one end of the spring is attached, the other end abutting a gravity nut 22, whose position is adapted to be adjusted with respect to the tension rod by means of a threaded portion upon the end of the rod. The rod and spring will tend to restrain any slight movement in themovable frame, but in order to prevent unusual swinging to and fro of the frame, incident to severe bumping together of cars or inequalities in the roadbed, chains 23 are pro,- vided which are. secured to the end sill 11 ofdthe car truck and to the forward crossro In order to provide a means for horizontally adjusting the movable frame with respect to the arms of the fixed frame and at the same time for horizontally adjusting the position of the dynamo, a threaded bolt 24 .is provided on each side of the sliding carriage which passes through a perforation 25 at either extremity of the cross-bar 3 and is held in position by lock nuts 26. The bolt also passes through and is secured to an offset portion 27 on each of the side bars. Through the operation of the lock nuts and associatedparts the movable carriage may be forced backward or forward upon the arms.

As shown in the drawings, the dynamo is '50 positioned with respect to the cross-rods that the axis of its armature shaft 28, upon which is mounted the pulley 29, is below the line ad oinlng the centers of the cross-rods and is substantially in line with the center line of the car-truck axle 30, .upon

which is mounted the pulley 31 adapted to transmit motion to pulley 29 by belt 32. This method of positioning the dynamo lnsures a substantial and compact construction.

The device described is positive in its action; possesses simple parts and is well adapted to stand the wear incident to its intended location. It is. furthermore, inexpensive and may be readily assembled and disassembled.

The provision of means whereby the dy On the outnamo is maintained in a substantially level position serves to prolong the length of life of the belt connecting the dynamo pulley and the axle pulley, for there is substantially a uniform tension upon the beltat all times, and also secures a steady supply of oil from the dynamo oil cups, which are also main-. tained in a level position. The means for mounting the sliding carriage and its hanger links secures the advantage that relatively long links may be used with a fixed height of dynamo and a given clearance below the lower sill of the carframe, and hence with a given swing of the generator there is a minimum elevation of its position. In other 30 words the movement of the generator is nearly directly toward and away from the driving pulley of the axle. The sliding carriage, as shown, is easily adjustable and its side bars, bearing throughout their length upon the projecting arms minimize the, tendency to bruise these projecting arms under jar and vibration. Moreover the sliding carriage and the hanger links constructed as shown are well adapted to resist any lateral thrust or tendency of the generator to swing sidewise of the truck, and there is small liability of breakage or wear inthese parts. By providing a single tension device positioned substantially opposite the dynamo pulley the tendency to bend the cross-rod is practically obviated inasmuch as the pull of the belt and the pullof the spring are substantially opposed. There is, further, little chance to pull the cross-rod out of parallelism with respect to the car truck axle. By the use of separate lower cross-rods the generator may be easily mounted or dismounted therefrom as' for purposes of repair, and if one rod becomes bent it may be readily removed and another substituted therefor, using the same hanger links. 1 f

It will thus be seen that a simple device is provided wherein the objects of the invention are achieved. j a

As many changes could be made in the above construction and many apparently widely diflere'nt embodiments of this invention could be made Without departing from the scope thereof, it is intended that all mat- 115 ter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the lan- 120 guage used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention, which. as a matter of language, might 125 be said to fall. therebetween.
