MEANS FOR SUPPORTING MOTORS AND MOTOR-FRAMES.

SPECIFICATION forming part of Letters Patent No. 557,049, dated March 24, 1896.

Application filed April 22, 1895.

To (0% whom it may concern:

Be it known that I, EDWIN S. BREED, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have made certain new and useful Improvements in Means for Supporting Motors and Motor-Trucks, of which the following is a specification.

My invention has relation to improvements on the construction shown in the patent to lValter S. Adams, No. 529,688, dated November 27, 1894. The construction shown in that patent involves the use of a motor-supporting frame, which comprises cross-bars se-' cured to the side bars of the axle-box frame, hangers depending from said cross-bars, and longitudinal bars secured to the hangers, the ends of which are detachably secured to the motor, each of the bars being rigidly secured to the hangers and which do not permit of any movement of said longitudinal bars in relation either to the motor or to the hangers or cross-bars which supported them. My improvem ents, although resembling said structure in many particulars, differ materially therefrom, in that the longitudinal bars for each motor are separate and disconnected from those for the other motor and from each other.

In my construction I employ the crossbars, hangers depending therefrom, and instead of employing the fixed longitudinal bars of the Adams structure and their zigzag conformation, which enables the right and left hand motors to be secured, I movably secure short longitudinal bars to the hangers between the extremes thereof, one end being movabl y connected with the motor, the other end being movably connected with one of the cross-bars. By this construction I enable the motor to lose some of its motion in the bars, which support themor it, and at the same time provide a structure easily assembled and disassembled, which will allow of ready repair should any of the parts become broken, and a ready adjustment of the motors thereto.

My invention therefore consists in the construction and combinationiof parts hereinafter described and f urtherpointed out in the claims. I

In the drawings forming part of this speci:

Serial No. 56,592. (No model.)

fication, Figure 1 is a plan View of a portion of a truck and a motor thereon, these parts being diagrammatically illustrated with my motor-supporting frame secured thereto and to the motor; Fig. 2, a longitudinal sectional elevation approximately on the line 2, Fig. 1; Fig. 3, a transverse sectional elevation on the line 3, Fig. 1; Fig. 4, an enlarged elevation of a portion of the cross-bar, side bar of the axle-box frame, and spring-support for the crossbar on the side bar; Fig. 5, a sectional elevation showing the said support; and Fig. 6, an enlarged side elevation of a portion of the hanger and the longitudinal bar, showing its connection with the hanger.

Similar numerals of reference indicate like parts throughout the several views.

I shall first describe the means for supporting the cross-bars and the hangers, which may be substantially the same as those de scribed and illustrated in the before-mentioned patent.

At 4. are the wheels and 5 the axles of the truck, upon which one or more motors 6 are secured in the usual way, which permits of a rotation of the free end of the motor about the axle, and at 7 is the casing for the fieldmagnets and armature.

Upon axle-boxes of a suitable construction (not shown) is suspended an axle-box frame, which preserves the parallelism of the axles and which has yokes forming pedestals for the axle-boxes, which comprises in this case side bars 8, intermediate yokes 9, forming the pedestals for the axle-boxes, and cross-bars 10, said axle-box frame being formed of a single homogeneous piece of metal, as shown. in the patent to John A. Brill, No. 492,525, dated February 28, 1893, to which cross-reference is here made, or otherwise, as desired. Upon the side bars 8 rest spring-cushions 11, which may be either in the form of rubber blocks or spiral springs, and upon these cushions rests the fiat end 12 of the cross-bars 13, the cross-bars in this case being dropped below the plane of the part 12 by means of the twisted and downwardly-bent neck 14.

. For elastically supporting the cross-bars from the side bars I have illustrated the form of elastic'cushion shown in the patent to Adams before recited, which, however, may

or may not be employed, and an elastic support for the cross-bars may be omitted altogether Without departing from the spirit of my invention. The construction of this elastic support is as follows: At the desired point of location for the cross-bar the side bar 8 is apertured, through which aperture extends a headed bolt 15, its nut 16 engaging V the bottom of the side bar and its enlarged head 17 engaging a cap 18, which rests upon the top of the rubber cushion 11. The cushion is seated in a plate 19, which in turn rests upon the top of the side bar 8, and between the plate 19 and the plate 12 of the cross-bar, which latter rests upon the cap 18, extend tie and guide bolts 20, which secure the plates 12 and 19 together, and at the same time allow the plate 12 of the cross-bar to move up and down thereon and form restraining guides for the movement of the cap 18, the latter being provided with grooves, as shown in Fig. 5, in which the bolts 20 lie.

Thus far my invention does not diifer materially from the construction disclosed in the patent to Adams aforesaid, the object of my invention being to support the motor upon this supplemental frame by bars entirely independent of each other, and movably support these latter bars.

I secure to the cross-bars 13 at the desired points, which of course is determined by the width of the motor-casing, reversed hangers 21 having one flat face 22 secured to the crossbar, as shown in Fig. 3, and a lip 23 resting on top of the cross-bar, as shown in Figs. 1 and 2, and a face 24; lying in aplane at right angles to the crossbar, which is effected by twisting the hanger, as at 25, the face 24 being provided with a lip 26, through which face 24 passes a strong stud 27, projecting from and securely fastened to the face 24: of the hanger, which stud may be provided with a nut or enlargement on the end, if desired. The hangers depend below the cross-bars to a degree determined by the desired elevation or depression of the motor-casing, and as this form of suspension is designed especially for the support of a motor which is provided with lugs 29 on the side of its casing the position of these lugs will of course determine the amount of drop of the hangers.

At 30 are the independent longitudinal bars, each bar being provided between its extremes with a slot 31, and at the end 32, which is to embrace and engage the motor, it is provided with a hole 32 large enough to take the lug 29 on the motor-casing, the other end of the bar being provided with an outwardly-extending goose-neck 33 having a rounded nose 34 at its extreme, which nose passes through a hole 35 formed at the proper point in the cross-bar. As shown, each one of these lon gitudinal bars passes through the cross-bar at one end, engages the stud on the hanger by means of the slot 31, normally rests upon the lower lip 26 thereof, and at the other extreme movably engages the motor and its casing by means of the hole 32 formed there in, and in this way the weight of the motor is taken on the independent longitudinal bars, each capable of having movement conjointly or independently of the other, which bars are supported upon the hangers, which with the cross-bars form a supplemental and centrallylocated motor-supporting frame suspended solely by the side beams of the truck, the connection between the longitudinal bars of the supplemental frame and the motor being had between the extremes or the front and rear ends respectively of the latter, thus in ,a measure relieving the axle of the weight of the motor and confining the'motions of the frame to that of the motor itself instead of causing it to partake of the movements of the car-body.

I prefer that the slot 31 should be larger than the diameter of the stud 27, so that the longitudinal bar can have not only a longitudinal motion on the lip 26 of the hanger, but also a vibrational motion to a limited extent thereon, the strain on the bar being taken by the lip 26, the stud limiting and guiding the movements of the bar, and I also prefer that the hole 35 in the crossbar 13 should be sufliciently large to allow of a free play of the nose 34 therein, so as to permit of vibrational as well as longitudinal play of the bar 30, and that the connection 32 of said bar be such that the lug on the motor can rotate to a limited extent, within the hole 32.

From the foregoing construction it will be apparent that the motor-supporting frame is very readily assembled and disassembled, and should one of they longitudinal bars break or become bent it does not necessitate the removal of the entire frame, but each one of the bars can be separately removed or replaced without affecting the condition or position of the other parts of the frame.

To strengthen the frame longitudinally I prefer to employ tie-bolts 36, which pass through apertures 37 in the cross-bars and which are provided with lock-nuts, as shown in Fig. 1, to tie the cross-bars together.

By the use of my construction the motor can be readily dismantled from the supporting-frame, and the adjustment of the said frame to accommodate it to motor-casings of varying widths can be readily had by merely adjusting the hangers on the cross-bars to suit the necessities of the case.

It is apparent that my invention can be otherwise embodied than in the particular details of construction herein shown and described Without departing from the spirit thereof.
