Belt known that l, GEonon D, Mifx'sixe, a citizen of the United States of America, residingat New York city, in the county and State. of New York, have invented, certain new; and useful Improvements in W'heel- Mounts for Vehicles; and I do hereby declare the followirgto be; a full, clear, and exactwdescription of the invention, such as will enable-others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form'a part of this specification.

My invention relates to wheel-mounts for vehicles, and more especially for motor-vehicles, to permit each wheel of. the velt icle to have separate and independent. vertical movement,- said movement being cushioned and'frictionally retarded, and to details of construction hereizafter particularly described and claimed.

, Referringto the drawings, in which like ,parts are similarly designated, Figure 1;-is an elevation embodyirg one form of my invention shown applied to the driving-wheel of an automobile. Fig. v2 is a plan view of the same, and Fig. 3 is an end view. Fig. 4is a modification of the cushioning device. Fig.

5 shows another form of cushioning device.

Fig. 6 illustrates the device, in elevation and partly in section, designed for a front or steering wheel. Fig. 7 is a plan of the same. Fig. 8 is a modification of a steering-wheel- Inount, andFig. 9 isa view of a similar mount for a driven Wheel.

Referring moreparticularlv to Figs. 1, 2, and 3, the device is applicable to automobiles as row constructed by cutting off the Wheel-axle spindle and clamping the device on theend of the axle, and said device consists ofv a rigid arm 10, on which is cast or otherwise secured a split clamping-sleeve 11, the sleeve being clamped tight hybolis 12 or otherwise'secured on the square (.(l oftlae cut axle, or the axle ends may be formed in or secured to this rigid arm in any desired marner. -The arm is substantially T-shaped, the head 13 being arcuate and provided with, preferably, but not necessarily, two slots 14,

- struck from 17 as a. center, and also provided 1 or ew Yornr, N, y, a K FOR-.- VEHICLEg Letters Patent.- Patented at its upper-part with a plate or case 15, in which the top of a coil-spring seats, andto the forward end of the arm is hinged orpivoted on abolt 17 asimilarly-shaped arm 18, whose head 20 carries two pins 19, preferably brazed into the head of arm 18,- amlwhioh project entirely through the slots in the head 13 and are secured to a frictiOn-platefll, by nuts 22, so that when the swinging arm 18 moves on 17 as a pivot the plate 21in frictional contact with the head 13 of the fixed arm willhave like movement. The head20 of the swingirg arm 18 has a plate or pocket 23 on its lower end in vertical alinement with seat 15 when the axesof the twoarms lie in the same plane to receive the lowerend of the spring 16. In the seat 23. andjunder the lower end of the spring 16 is aplate 24, raise d, by a scre.w-25, so that Within determined lim its the tension of the spring may be increased at will. Onthe arm 18 andin alirement with-the axle of the vehiclewhen the two arms-10 and 18 aretogetherthere is-a boss..26,-

intowvhich is shrunk the wheel-spindle 27'." In the particular case illustrated this wheel is the driving-wheel QB-and has fixedto it the hollow sprocket-wheel29. In thelsprocketwheel 29 is the customary expansion brakeband, which is a split rir g fastened at its mid dleand having between its free endsanexpandin r-ca-m. In order to accommodate such a rake, the swinging arm 18,has.apin 30, on which the split ring is secured at its middle, and above this pin isa boss31, in which is jourraled a rod 32, thatcarries at the end which projects into thehollow sprocket the cam 33 to expand or move apart the free ends of the band, as .is usually done,

On the opposite end ofrod 32 is the brakeactuatiig lever-34, conrected by wire or cord 35 to the operating device at the drivers seat. \Vhen the tie-rod or body-brace 36 is secured to the h uh end of the axle, the-ears in which the rod, is secured are cut off, and an ear 3? is provided on the boss 11, through which car the bolt 38, which holds the end of the brace passes, beirg screwed into arm 10.

"lheoperation is as follows: Each wheel of the vehicle when passing over an obstructiom such as a rut orstone in the road, will be forced upward. and move in the arc of a circle rebound suddenly, by reason of the friction of plate 21 on the head 13 of the fixed arm, said plate being rigidly connected with the swinging member 18 20 by bolts 19. Such a device is applicable to all the wheels, whether driven or not.

Figs. 6 and 7 show my invention so constructed as to be applied to a movable or steering wheel. In this case the relatively fixed arm or member 110 hasavertical hollow post 40, through which the usual ivot-pin securing the wheel to the front ax e passes. This member also has a depending lug 41, to which is connected the usual actuating-bar 42 to move the device on its vertical pivot. The boss 26 on the swinging arm 118 receives the wheel-spindle on which the wheel is mounted. The boss 31 and pin 30 are omitted, since the wheel is not a driven wheel; but in other respects the structure is identical in its construction and operation with that shown in Figs. 1, 2, and 3.

In place of a' simple spring between the fixed and swinging members I use, especially for heavy vehicles, a modified form of cushioning device, as shown in Figs. 4 and 5. In Fig. 4 the upper plate 15 carries a cylinder 44, pivoted to said plate at 45, so as to have a short swing to automatically adjust itself in alinement with the lower cylinder 46, pivoted at 47 in the lower plate 23 of the swinging arm, so that the upper cylinder will not bind in the lower one, in which it works when the swinging arm assumes its various angular positions. The lower cylinder has an airinlet 48, closed by a valve 49, so that the cylinders will be filled with air to form an aircushion that will assist the spring 16 mounted within the cylinders, as shown. In Fig. 5 I make use of a cataract. The upper cylinder 50 is closed at both ends, but has a perforation 51 in its lower end. The cylinder 50 is pivoted in plate 15 at 52. The lower cylinder 57 is pivoted in plate 23 at 53 and is open at its upper end to receive the cylinder 50, which works in it as a piston. Oil or other liquid is placed in the lower cylinder, so that when the piston is forced down the oil will pass through perforation 51 into thehollow piston, and thereby retard the upward movement of the wheel, at the same time compressingnithe air in the hollow piston. A spring 57 surroundstheeyhnders, its upper end limited by a flange 54 on platelh andi'ts" lower end adjustably held by internallythreaded rings 55 on the threaded portion 56 of the cylinder 57.

Figs. 8 and 9 show two forms where the device is attached to the frame of a motorvehicle, said frame acting in this case as the rigid arm. 60 is a portion of the side member of the vehicle-frame, having a pivot-block 61 secured thereto and a depending areuate portion or member 62 struck from 61 as a center. The member 62 has two slots 63, through which pass pins 64, fixed in the arcuate portion 65 of the swinging member 66 pivoted in 61. On the opposite side or back of piece 62 is a friction-plate 67, connected to the arcuate portion 65 by the pins 64, so that said plate and swinging arcuate portion 65 move in unison one on one side and the other on the opposite side of plate 62. A spring 68 is suitably placed between the swinging and the relatively fixed members 66 and 60. On the swinging member is secured a fork 69, having a pin 70 therein, said pin being keyed or otherwise rigidly secured to a steeringwheel spindle, as is customary. The lower end of the pin 70 is squared, as shown at 71, to receive a lever 7 2, to which is connected the steering rod. (Not shown.) Fig. 9 shows a mount for a driven wheel identical with that shown in Fig. 8, excepting that the swinging member 65 has a boss 72, into which isshrunk the wheel-spindle.

From the above description it will be seen that in all the forms illustrated the wheels, which are each independently movable on the pivots, will not impart a sudden jar to the vehicle,for when the wheel strikes an obstruction it is not suddenly lifted, but moves around the pivot-point of the swinging arm, and is thereby assisted in rolling over the obstruction, while the body of the vehicle and the other wheels remain unaffected thereby.

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