One end is adj ustably connected 1 designates a motor-ear truck which is dewith the arm 21 of the T-shaped brake-shaft, signed to have a motor mechanism centrally said arm being perforated to permit the ad- 95 45 mounted on it in the usual manner, and the justment of the bar 22 to vary the power ot truck and the motor mechanism may be of the brake mechanism, and the diameter of any desired construct-ion. the drum may also be varied in order to ob- One of the car-Wheels, preferably the Wheel tain the desired power for the application of 2, is provided with a friction ring oi'plate 8, the brake. The other arm of the bar 22 is slot- 10o o which may be formed integral with the carted at 24, and the bar 22 and the lever 2S have Wheel or be secured thereto, and which is en a limited movement independent of each other. A spring has one end secured to the inner edge of the oscillating or shifting bar 23, and its other end is free and engages the slotted end of the bar 22 and is arranged in the bifurcation thereof, whereby when the brake is applied the bar 22 irst engages a spring and yieldingly forces the frictionclutch in engagement with the car-wheel until the full power of the operating mechanism is felt. This spring maybe made of any desired strength to cause the friction-clutch to engage the car-wheel gradually and with increasing force, and it serves to cushion the parts and to prevent injury to them. The outer end of the oscillating or shifting bar 23-is pivoted to an eyebolt or bearing 26, and the inner end of the bar 23 is forked and is received in an annular groove of the d rum G, When the T-shaped lever is operated by either of the rods 17 or 1S, the drum will be reciprocated to carry the friction-clutch into en gagement with the car-wheel 2. The bearing bracket or arm 20, which fulcrums the lever 12, is preferably supported by a brace 27, having one end secured to the arm or bearing-bracket by the fuleruming pivot or bolt and its other end secured to the frame of the truck.
In order to enable the brake mechanism to be connected at either end of the motor-car with the brake mechanism of a trailer, a transverse lever 28 is centrally fnlcrumed on the bracket-arm 29, and has one end connected with the brake-rod 9 by a short rod 80, whereby when the brake-rod 9 is drawn in the direction of the drum the transverse lever 28 will be operated. The transverse lever 28 isconnected with the inner ends of rods 3l and 32, extending from the transverse lever 28 in opposite directions and preferably terminatin g in hooks to en able them tobe readily detachably connected with the brake-rod of a trailer by a chain or the like.
It will be seen that the brake is simple and comparatively inexpensive in construction, that it is especially adapted for motor-cars, and ythat as soon as the friction-clutch is thrown in engagement with the car-wheel the brake will be automatically applied. It will also be apparent that the brake can be operated from either end of a motor-car and that it is adapted to operate the brake mechanism of a trailer when either end of the motor-car is coupled to the latter.
Changes in the form, proportion, and minor details of construction may be resorted to without departing from the principle or sacriiicing any advantages of the invention.
