ports, of which-the followingis a specification,

-This invention relates to a new and improved resilient support, and more particularly to a cushioned support. especially adapted for use in connection with thesupport of motors in motor vehicles,

v v The road v brations and shocksare a great source of motor deterioration, and-it is highly desirable that the motor be cushioned against such shocks in so far as is possible.

Due to the connection'between the -.motor and the driving means of the vehicle, and also due to the weightof the motor, it is of vnecessity required to be substantially im- 'movably attached to the vehicle frame. This vconnection has been made either directly to the frame or to sub-frame and has generally consisted of either-a four point or three-point suspension; YVith the four-point suspension the'motor is supported substan tially at its four corners and with long heavy motors a rigid frame is required and the motor connection so stifi'ens the frame thatthe motor receives'fully all shocks received by the frame. The three-point suspension was devised in the attempt to permit the frame to be more yielding and-to minimize the stiffening of the frame due tothe motor connection. It has been found, however, that a resilient method of attaching themotor to the frame which will permit a small amount of play will Very materially reduce trans mission of shocks-to the motor and consequently reduce the injury to the motor dueto minor roadvibrations. Resilient means are provided to take up the play between the motor and the frame in such manner as to prevent any lost motionand as to eliminate rebound shocks. w

It is anobject of the present invention to provide means of the character described which are adapted to serve as a motor support and to cushion the connection between the motor and the vehicle frame.

It is also an object to provide a cushion support which is rugged in construction and simple in design, so as to stand up under the heavy stresses involved.

It is a further object to provide a device of this character which is composed of but few parts and which may be readily manufactured and installed at comparatively small expense. 7

Other and further objects will appear as the description proceeds; A

B oadly my inven io compris h at plication of a resilient support to one end of the motor, it having been found that a completely resiliently supported motor is rendered impractical by the inertia of the heavy motor. The resilient connection is designed to cushion shocks to prevent excessive rebound. This construction permits the frame to be less rigid andconsequently to absorb a portionof the shocks.

More particularly the invention involves the application of the resilient support to the forward portion of the engine, this being the more desirable since the rear portion is connected to the driving members and; hence should be as stable aspossible.

I have illustrated a preferred embodiment of my invention in the accompanying drawingS, in Which Figure 1 is a somewhat diagrammatic viewillustrating the relation of the engine to the frame; and i Figure 2 is a sectional detail of my cushioned motor support. f

As shown in Figure 1, the motor-3 has its rear portion 4l connected to brackets 5: 6X- tending inwardly from the vehicle frame 6. The crank case front arm 7 is supported upon the frame front motor. supports 8. The construction of this supporting assembly is illustrated in detail in Figure 2. The frame side rail 9 has the frame front motor support 8 secured thereto in any desirable manner. This frame front motor support 8.. is providedwith the reinforcement 10. The crank case upper half front arm 11 extends above the support 8 and the two members are provided with registering openings 12 and 13 respectively. The Washer 14 is seated in a recess at the upper end of the opening 12 and is provided with a spherical seat 15. The bolt 16 is provided with a head 17 having the spherical lower surface 18 coacting with the seat 15. The

bolt extends 11, while its ends engage the member 8. A cotter pin 21 is passed through the bolt 16 and serves to hold the spring in assembled relation upon the bolt. The portion of the bolt 16 below the member 13 carries the oppositely faced dished washers 22 and 23, between which is carried the coil spring 24.

In the use of this resilient support, the spring 20 has a certain amount of permanent deformation due to the wei ht of the motor. The nut 19 is preferably adpxsted so that the spring 24 is constantly under a predetermined compression. Shocks which are recieved by the vehicle frame 9 are cushioned by the spring 20 and largely absorbed there by before reaching the motor arm 11. The spring 24 serves to somewhat stiffen the resistance of the spring 20 and also serves to retard and reduce the rebound of the arm 11 after compression of the spring 20 due to shock. The spherical bearing between the bolt 16 and the washer 14 upon the arm 11, taken in connection with the fact that the opening 12 is of a size sufficient to provide clearance with the bolt 16, serves to permit a limited amount of lateral play of the motor frame without binding the cushion means. This play'is necessary in order to prevent a stiffening effect upon the frame due to the connection.

While I' have illustrated a preferred form of resilient support, it is to be understood that m invention broadly is independent of t is specific cushioning means utilized, and changes are contemplated Within the scope of the appended claims without departing from the spirit of the invention.

I claim:

1. Resilient means for supporting a motor upon a vehicle frame comprising a pair of load-receiving brackets associated with the frame, a pair of load-carrying brackets associated with the motor, each motor bracket extending above a frame bracket, a leaf spring interposed between the two brackets, a. spherical seat associated with the motor bracket, a bolt having a head coacting with said seat and having its shank pass down-:

ward-1y through the spring and frame bracket, and resilient means associated with the lower end of the bolt and adapted to oppose.

separation of the brackets.

2. Resilient means for supporting a motor upon a vehicle frame comprising a pair of load-receiving brackets associated with the.

cap upon the lower end of the bolt, and a coil spring interposed between the cap and the frame bracket and adapted to oppose separation of the brackets.

3. Resilient means for supporting a motor upon a vehicle frame comprising a loadreceiving bracket associated with the frame, a load-carrying bracket associated with the motor, a leaf spring interposed between the two brackets, a spherical seat associated with the motor bracket, a bolt having a head coacting with said seat and having its shank pass downwardly through the sprin and frame bracket, means associated witi the shank below the leaf spring adapted to maintain the motor bracket, spherical seat bolt and spring in assembled relation, a cap upon the lower end of the bolt, and a coil spring interposed between the cap and the frame bracket and adapted to oppose separation of the brackets.
