UNITED STATES PATENT OFFICE.

JOSEPH HOUGH, OF BUOKINGHAM, AND JACOB MOORE, OF BART, PENNSYLVANIA.

CAR-BRAKE.

. Specification of Letters Patent No. 22,291, dated December 14, 1868.

To all whom it may concern:

Be it known that we, JOSEPH HOUGH, of Buckingham, in the county of Bucks and State of Pennsylvania, and JACOB MOORE, of Bart, in the county of Lancaster, in the same State, have invented a new and Improved Railroad-Oar Brake; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1, is a vertical longitudinal section of a car truck with our improved brake applied to it. w, m, Fig. 3, shows the plane of section. .Fig. 2, is a vertical transverse section of ditto taken in the line 1 y, Fig. 3. Fig. 3, is a plan or top view of ditto.

Similar letters of reference indicate corresponding parts in the several figures.

To enable those skilled in the art to fully understand and construct our invention we will proceed to describe it.

A, represents a rectangular frame in which the axles B, B, of the wheels O, are placed as usual. In each side of the frame A, two levers D, D, are placed, said levers working on fulcrum pins (1. To the lower end of each lever D, a shoe E, is attached, said shoes being below the horizontal plane in which the axles B, B, are placed, as shown clearly in Fig. 1. To the upper end of each lever D, a horizontal slide F, is attached, by a pivot or pin Z). These slides F, are fitted in grooves c, in the upper part of the frame A, see Fig. 2,, and two slides at each side of the frame shown in Figs. 1 and 3. To the outer end of each slide F, and to its under side a shoe G, is attached. See Figs. 1 and 2. The lower ends of the levers D, at opposite sides of the'frame A, i are connected by bars H, H, and these bars are connected by rods I, I, to the lower ends of two levers J, J, which are secured in a longitudinal bar K, by fulcrum pins (2'. To the upper end of each lever J, a rod 6, is attached, and the inner ends of these rods are connected to a horizontal lever L, near its center and at opposite sides thereof. To each end of the lever L, a rod M is attached. See Fig. 3.

From the above description it will be seen that by drawing outward the rods M, as indicated by the arrows 1, the lever L, rods 6, and levers J, will be moved in the directions indicated by their respective arrows, and the bars H, and levers D, will be moved as indicated by the arrows 3, and the shoes IE, will be pressed against the wheels C, at the same time the slides F, will be moved in the direct-ion indicated by the arrows l, and the shoes G, will be pressed against the upper parts of the wheels and directly opposite the shoes E. Both shoes E, G, of each wheel it will be seen are operated simultaneously and as they press upon the wheels at opposite sides, the axles will not be subjected to any undue strain and a greater amount of friction will be produced than if one shoe only were applied to each wheel.

The within described arrangement of levers and slides is exceedingly simple, but little power is lost during its transmission from the rods M, to the shoes F, G, and the device may be applied at a reasonable cost.

Having thus described our invention what we claim as new and desire to secure by Letters Patent, is, l

The arrangement and combination of the slides F, and levers D, J, as and for the purposes here-in shown and described.

JOSEPH HOUGH. JACOB MOOREI
