CAR-BRAKE.

SPECIFICATION forming part of Letters Patent N 0. 782,961, dated February 21, 1905.

Application filed January 11, 1904. Serial No. 188,532.

To all whom it may concern:

Be it known that I, JOHN B. HAUG, residing at St. Benedict, in the county of Nemaha and State of Kansas, have invented certain useful Improvements in Car-Brakes; andl dohereby declare that thefollowing is a full, clear, and exact description 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, which form a part of this specification.

This invention relates to a new and novel improvement in car-brakes.

The object of my invention is to provide a car-brake so constructed that the car-wheel will be engaged upon opposite'points, the friction being applied to the faces of the wheel instead of to the peripheral surface of the wheel; and my invention embodies certain other combinations, as will be described more fully hereinafter and finally pointed out in the claims.

In the accompanying drawings I have shown in Figure 1 a bottom view of a car-brake embodying my invention. Fig. 2 shows a top view of a car-brake constructed according to my invention with portions removed, while Fig. 3 shows an end view of my car-brake.

In carrying out the aim of my invention I use a suitable supporting-bar A, of any suitable material, which at each end is provided with the extensions 4, as clearly disclosed in Fig. 1. This supporting-bar A is provided at opposite points and near each end with the projecting ears 2 2 and 3 3, as clearly disclosed in Fig. 1. Each of these cars is provided with a supporting-pin 1, and each pin supports an ordinary roller 6, as disclosed in Fig. 2. Intermediate of its ends this supporting-bar A is provided with a stub-shaft 8, which is supported above by means of a plate 7 as shown in Fig. 2, and beyond which plate 7 this stub-shaft 8 extends, as disclosed in Fig. 3. Above, this plate is provided with a T-shaped operating-lever 9, to the projecting lever 9' of which is secured a suitable connecting-rod, fixed to any brake or other operating means.

Secured to the end stub-shaftsff and to the intermediate stub-shafts f are thepinions 0, as disclosed in Fig. 2. These stubshafts ff extend through the supportingbar A, as disclosed in Fig. 1, and above also extend through a suitable cap-plate 12, as is disclosed in Fig. 2, these cap-plates 12 being secured by means of suitable bolts a, and these cap-plates 12 are also adapted to receive the pins 1, as is shown in Fig. 2, to assist in properly supporting the rollers Z). Secured to one end of each of the stub-shaftsf and f is an arm 0, so that these stub-shafts f are in the form of rock-shafts, being actuated from side to side by means of the arms 4, as is disclosed in Figs. 1 and 2. In referring to Fig. 2 it will be noticed that I use these pinions c in pairs and that the arms 6 are extended parallel to one another and that each set of arms is united by a connecting-rod 13, secured to the arms by means of suitable pins 1.

Extending from the pin 1 of each of the innermost arms 0 upon one side is the connecting-bar D, secured, by means of a pin 1, to the T-shaped operating-lever, while the opposite set of arms 6, by means of a connectingbar D, held by the pins 1, is also fastened to the T-shaped operating-lever 9.

Held adjacent each set of pinions 0 upon opposite sides are the racks B and B, as is shown in Fig. 2. These racks are of such a width that the rollers b properly hold these racks in engagement with the adjacent pinions (2. The racks B are somewhat shorter than the racks B and end adjacent the inner face of the car-wheels K, these racks being provided with a brake-shoe 5, as is shown in the drawings, while the racks B have an angular extension 6, to the end of which is secured abrake-shoe 5", these two brake-

shoes

5 and 5 coming in alinement, there being two sets of these brake-shoes upon opposite sides, so that two car-wheels are simultaneously engaged when the brake is brought into operation. In order that the brake-shoes 5 and 5may normally be held apart, permitting the free rotation of the car-wheels K, I provide'the spring 14, secured by means of the pins 1, this spring at one end being fastened to the bar A and at the opposite end, to the T-shaped opcrating-lever 9, so that normally these brakeshoes are held apart. Now when it is desired to apply the brake the operator would draw the connecting-rod 10 forward by any suitable means, which would rock the connected stubshafts f and f, actuating the pinions cto carry the racks B and B toward one another, so that the brake-

shoes

5 and 5 would travel toward one another and between them impinge on the car-wheel K, as is disclosed in Figs. 1 and 2, to check the rotation of the car-wheel. As soon as the connecting-rod is released the spring lei actuates the mechanism to release the brake-shoes.

The supporting-bar A may be secured to the bottom of the car by any suitable means, such as by means of a chain or rod, or, if desired, these supporting-bars A maybe secured in any suitable manner to the car-axles. Further, it is of course understood that where cars are provided with four or more wheels each set of wheels could be provided with one of my brakes.

In Fig. 3 I have disclosed a side view illustrating the position of the outer brake-shoes 5.

This brake is adapted to be used in connection with street-cars, railway-cars, automobiles, and, in fact, any ordinary vehicle, as the bar 10 could be operated by foot. The brake engaging the side or tire of the wheel would not damage any elastic tire that might be secured to the wheel should this brake be used in connection with an automobile or pleasure vehicle.

It is of course understood that the mechanism may be made of suitable sizes to acommodate the sizes of the various vehicles in connection with which the same would be used.

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

1. In abrake, the combination of the following mechanism, to wit: a supporting-bar, an operating-lever pivotally secured to said sup- 2. In a device of the character described, the

combination with a supporting-bar, of an operating-lever, a spring to normally force said operating-lever in one direction, a rock-shaft journaled in each end of said supporting-bar, a bar extending from each rock-shaft and secured to said operating-lever,apinion mounted upon each rock-shaft, a rack in engagement with each of said pinions, a brake-shoe secured to the end of said rack, said brake-shoe being adapted to come into engagement with the inner face of a suitable car-wheel, a supportingroller positioned adjacent said rack holding said rack in engagement with its pinion, a second rack in engagement with each pinion, a

' second roller holding said second rack in engagement with its pinion upon the side opposite the first-mentioned rack, and a brakeshoe secured to each of said second-mentioned racks adapted to engage the face of a suitable car-wheel at a point opposite where the same is engaged by aforesaid first-mentioned brakeshoe, all arranged substantially as and for the purpose set forth.

In testimony whereof I have affixed my signature in presence of two witnesses.

JOHN B. HAUG.
