BRAKE-HIGGINS: FOR SELF-PROPELLED VEHICLES- Specification of Letters Patent.

Patented June 26, 1906.

Application filed May 9, 1905. Serial No. 259.607.

To all whom it may concern:

Be it known that I, CHARLES O. SNYnEn, a citizen of the United States, residing in the city of New York, in the borough of Manhattan and State of New York, have invented certain new and useful Improvements in BrakeRigging for Self-Propelled Vehicles, of which the following is a full, clear, and exact description.

This invention relates to the brakerigging of self-propelling vehicles.

In that class of vehicles where the brake in the form of a strap or shoes acting upon a.

This invention isdesigned to overcomethis defect, and to that end consists in so mounting the stationary members of the brake that the strain referred to is communicated to the body of the vehicle instead of to Y the sleeve mentioned and at a point where it will be distributed in a downward direction throughout all of the springs of the vehicle.

In the drawings accompanying and form ing a part of this specification a form of my invention is illustrated, wherein- Figure 1 is an elevation of a portion of an automobile, illustrating a practical embodiment of my'invention. Fig. 2 is a similar view with the wheel and spring removed and the brake-drum shown in longitudinal section. Fig. 3 is an enlarged View of the end of the brake-carrier, certain parts being broken away and shown in longitudinal section. Fig. 4 is a top plan view of parts shown in Figs. 1 and 2, certain parts being shown in horizontal section; and Fig. 5 is a view from the end in about the line 5 5 of Fig. 4.

Only such portions of the vehicle have been illustrated as are necessary to a complete understanding of the invention.

The bottom framingnmember 11 is in'the present instance a channel-iron havin a web portion 12 and two horizontally-disposed flanges 13 13. This is the usual floor-beam of the car or carriage and from which the the parts are supported. The wheel designated in a general way by 15 may be of any convenient construction, having a brakedrum 16 secured thereto, which brake-drum, in the present instance, is intended for engagement upon the inner perimeter by a pair of rake-shoes 17, each 0 which constitutes a half-circle, and is provided in the form illustrated with an eye 18 at its. lower end. Such eyes are pivoted by means of a pivot member 19, and their upper ends are controlled by a toggle comprising a pair of links 190, having suitable connections with the free ends of the shoes. Such links are pivoted at their knuckles to a link 20, which is in turn pivoted toa rock-arm 21, carried by a rockshaft 22. The rock-shaft 22 and the pivot member 19 are carried by a brake-carrying device 25, which brake-carrying device is, in the present instance, in the nature of .a channel-iron or truss, it having a web portion 26 and horizontally-disposed flanges 27 to give it stiffness and rigidity, and for the purpose of lightness it may be of skeleton work, as shown.

The axle-30, to which the wheel is fast and whichwill be driven in some suitable manner, has a sleeve 31 surrounding it, which sleeve carries a bearing-box 32, containing the usual rollers or other bearing devices for the axle. There is a sleeve 33 loose upon the sleeve 31 and held from longitudinal movement by means of a collar 34. -The sleeve 33 has a flange 35 which may be fastened, as by rivets 36, to the end oftlie brake-carrier and surround an o ening 37 in such brake-carrier, which may e concentric with the sleeve 31 and axle 30. Assuming that the rear axle is the one illustrated, the brakecarrier will project forwardly and inwardly tothe bodybeam and be secured thereto in some suitable manner. In the present instance a bracket 40, having side members 41 to fit upon the side of the beam, may be secured b means of bolts 42 to the same, a suitable illing 43 being inserted in the hollow portion of the channel-iron to give greater stability to the bracket. The connection between the end of the brake-carrier and the bracket may be .by means of a turnbuckle 44, engaging a screw-threaded rod 45 from the end of the carrier, and a screw-threaded rod 46, having an e e 47, surrounding a ivot 48 in' the brac et 40." The turnbuc e affords means of adjustment, and the pivot will permit movement of the carrier when the axle and wheel move vertically with relation to the body. The spring 50 is shown resting upon the sleeve 31 and fastened to the same by means of clips 53. Its forward end is supported by bracket through the link 51 and arm 52. All the parts of the brake controlled by the carrier are concentrically mounted upon the sleeve, and consequently in similar relation to the wheel and its brake parts. The a plication of the brake will be b means of a l ver' 55, fast upon the rock-s aft 22, upon moving which to straighten the toggle the brake-shoes will be forced into engage ment with the brake-drum. The twisting strain thus brought upon the shoes will now be-transmitted to the brake-carrier 25, and this member being pivoted about the axle will tend to swing downward at its forward end, which tendency will be exerted upon the middle of the VhlClel)O(l V, and thus distributed evenly throughout the springs. A footboard 60 may be carried by a bracket 61, also dependent from the bracket 40. By this means one substantial bracket may e at tached to the framing member of the. vehicle in a strong manner and the multiplicity of attached devices be obviated.

In Fig. 3 a bracket 63 is shown for carrying the rock-shaft 22, such bracket being fastened by rivets 64 to the horizontal member of the carrier and by rivets 65 to the web member thereof, and the bracket 66 for carrying the pivot member 19 may be suitably riveted or bolted to the. frame of such carrier and receive the enlarged portion 67 of said pivot-pin. The brake-carrying lever 25 will serve to'a certain extent as a radius-bar.

Various details of construction may of course be changed as various condu'nims of I employment demand without departing from pivoted to said radius-rod, and having a link connection with said shoe, and means for im parting tension to said lever.

2. .In a brake-rigging, a rotating drum. a radiusrocl attached to the vehicle-body and extending into proximity to said drum. a pair of brake-shoes pivoted to said radiusrod and extending peripherally around the drum in opposite directions, and a lever also pivoted to said radius-rod and having a pair of link connections to the respective shoes.

3. In a brake-rigging, a rotating drum lixed to the vehicle-wheel, a radius-rod attached to a portion of the vehicle-body and extending into proximity to said drum. said radiusrod being formed of a pair of diverging truss members. having an intermediate web with perforations or openings therein, a lever piv oted within said radius-rod, a brake-shoe having a link connection to said lever, and means for pivotally connecting said brakeshoe to said radius-rod.

In witness whereof I subscribe my signa ture in the presence of two witnesses.
