IPERCY E. BARKER, OF BUFFALO, NEW YORK, ASSIGNOR T0 BURNET'IE F. STEPHENSON, 0F DETROIT, MICHIGAN.
VEHICLE CUSHIONING DEVICE.
Specification of Letters Patent.
Patented May 23, 1911.
Application filed August 10, 1910. Serial No. 576,542.
To all whom 'it may concern:
Be it known that I, PERCY E. BARKER, a
citizen of the United States of America, re-' siding at Buffalo, county of Erie, and State of New York, have invented certain new and useful Improvements in Vehicle Cushioning Devices, of which the following is a full, clear, and exact description.
The general object of my invention has been to produce a device which, when connected with one of the axles of a vehicle, would relieve the vehicle frame and all of the parts carried by it from shocks and jolts caused by the vehicle passing over obstructions or other rough spots in its path of travel. In addition to this my device is so designed that it will prevent the side-swaying of the vehicle as it is driven over uneven parts of the road.
Many other advantages will result from the use of my invention as will be apparent to those skilled in the art.
Referring now to the accompanying drawings in which like letters of reference indicate corresponding parts in the several views and in which:
Figure 1 is a plan view of my device as applied to the vehicle frame. Fig. 2 is a sectional view taken on the line AB of Fig. 1. Fig. 3 is a diagrammatic rear end view of a vehicle equipped with my device.
Preferably my invention is applied to the rear end of the vehicle frame in a vertical posit-ion as shown in the drawings but it will be understood that it can be advantageously employed in a position horizontal to the frame.
The casing 5 incloses the main working parts of my device and this is preferably made in two parts-a cover 5 and a body portion 5 The body portion 5 is preferably made integral with a hub 6 and the cover 5 is preferably perforated or cut away as shown, to allow the hub 6 to pass slightly beyond and through it. The body portion 5 may be provided with side flanges 7 and 8 whereby the casing may be conveniently secured to the vehicle frame 9, but of course any other suitable means of attaching the casing to the frame may be employed if it is so desired.
Inclosed within the casing 5 are two gear segment disks 10 and 11 each of which is provided at its upper end with a lug 10 and 11 respectively. Each of the disks 10 and 11 is also provided with an inwardly extending flange collar 10 and 11 respectively. These flange collars 10 and 11 are carried by and surround the hub 6. One end of a shaft 12 rests in a shaft seat 13 provided in the body portion 5 of the casing 5. The other end of the shaft 12 is made integral with or secured to a shaft collar 14: which is revoluble around the flange collars 10 and 11". A bevel gear pinion 15 is rotatably mounted on the shaft 12 and this pinion meshes with each of the gear segment disks 10 and 11.
From the foregoing description it will be clear that when the body or frame of the vehicle, to which the casing is secured, tends to sway sidewise (whatever may be the cause of such tendency), the segment disks 10 and 11, to which the rods 20 and 21 are secured, will be prevented from relative rotation by the pinion 15. Furthermore, when the said vehicle body or frame tends to lower, the rods 20 and 21 will be pushed toward each other and, since under these conditions the pinion 15 will revolve, the extent of motion of one rod will be the same as that of the other no matter how great the movement may be. Thus the vehicle body will always be kept centrally over the rear axle. The functional purpose of the tension devices 23 is to frictionally hold the gear segment disks against rotation and thereby absorb all the shocks which might otherwise be conveyed from the axle to the vehicle body.
Clearly some modifications of the specific structure herein shown and described might be made without departing from the spiritof my invention and I do not wish it to be understood that I confine myself to the exact structure herein shown and described.
What I claim is:
1. The combination with a vehicle body and its axles of a cushioning device comprising gear segment disks rotatably mounted on said vehicle body, a gear pinion rotatably mounted between, and meshing with said disks, and rods pivotally mounted at their upper ends on said disks and at their lower ends on one of said vehicle axles.
