y FRICTION DRAFT-GEAR FOR RAILWAY-CARS.
SPECIFICATION forming part of Letters Patent No. 782,407, dated February 14, 1905.
Application iiled September 28, 1904. Serial No. 226,267.
Toa/ZZ whom t Ina/y concern:
Be it known that I, WILLIAM H. MINnR, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Friction Draft-Gear for Railway- Cars, of which the following is a specification.
My invention relates to improvements in friction draft-gear for railway-cars.
rIhe Object of my invention is to provide a friction draft-gear of a strong, simple, compact, efficient, and durable construction.
My invention consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described.
In the accompanying drawings, forming a part of this specification, Figure l is a central vertical longitudinal section of a friction draftgear embodying my invention. Fig. 2 is a plan view, partly in horizontal section. Fig. 3 is across-section on line3 3 of Fig. 1. Fig. 4 is adetail perspective view of the transversely or vertically movable friction-block.
In the drawings, A represents the longitudinal draft or center sills of a` car, and Al the front or cross sill.
B is the draw-bar of the coupler, and B the draft-iron connected to the draw-bar by a short Strap or yoke B2, extending through or around the head or Socket B3 of the draftiron. The draft-iron B has a straight frictionface I; on its lower side in Sliding frictional engagement with a stationary friction-plate C. The friction draft-iron B has oppositely-disposed double-inclined friction-faces b on its upper side in sliding frictional engagement with the corresponding double-inclined friction-faces d of the transversely or vertically movable friction-block D.
F F are the side plates or guide-castings secured by rivets f to the draft or center sills A A. Each of these side plates or guidecastings is furnished with integral bearings or ledges f to engage the ends of the flat steel springs G and with upwardly-inclined wings or flanges f2 to partially cover or inclose the springs on top, while permitting them to bend upward at their middle. Each of the side plates or guide-castings F is also provided with a plurality of upright guides f3 f4.75 to frictionally engage and guide the transverselymovable block D in its up-and-down movement. The friction-block D has an upright slot or groove d to receive the middle upright guide j4 of the side plate or guide-'casting F. The'stationary friction-plate C is removably secured to the'side plates or guide-castingsFby short bolts f6, which extend through the lower horizontal flanges f7 of the side plates or guide-castings F. rIhe side plates or guide-castings F are further provided with front and rear shouldersf18 to engage the front and rear ends of the'stationary friction-plate C, and thus relieve the bolts f6 from shearing strain. The friction-plate C is depressed or recessed at its sides to form shoulders c to fit between and engage the side plates or guide-castings F F. The transversely or vertically movable friction-block D has a central bearing or rib d2 to bear against the middle of the at springs G and coperate with the bearings f f on the side plates or guide-castings F, which engage the springs at their ends.
I claim- 1. In a friction draft-gear, the combination with a draw-bar and friction draft-iron Connected thereto and` having a straight frictionface on its lower side, and oppositely-disposed double-inclined friction-faces on its upper side, of a transversely or vertically movable friction-block having double-inclined frictionfaces engaging` the double-inclined frictionfaceson the draft-iron, and furnished with a central rib or bearing for a set of iiatsprings, a pair of side plates or guide-castings furnished with upright guides engaging said friction-block, and with integral bearings or ledges toengage the ends of a set of flat springs, a set of flat steel springs interposed between said friction-block and said side plates or guide-castings, and a stationary friction-plate removably secured to said side plates or guidecastings on the under side thereof, substantially as specified.
Q. In a friction draft-gear, the combination with a draw-bar and friction draft-iron connected thereto, havinga straight friction-face on its under side anddouble-incline frictionfaces on its upper side, of a sliding frictionplate engaging the straight friction-face of said draft-iron, a vertically-movable frictionblock having dou ble-incline friction-faces engaging said incline friction-faces of said draftiron, side plates orguide-castings having upright guides engaging said friction-block, and furnished With integral bearings or ledges to engage flat springs, and a series of flat steel springs interposed between said friction-block and said side plates or guide-castings, said friction-block having a rib or bearing engaging said springs, substantially as specified.
3. In a friction draft-gear, the combination with a draw-bar and friction draft-iron connected thereto, having a straight friction-face on its under side and double-incline frictionfaces on its upper side, of a sliding frictionplate engaging the straight friction-face of said draft-iron, a vertically-movable frictionblock having double-incline friction-faces engaging said incline friction-faces of said draftiron, side plates or guide-castings having upright guides engaging said friction-block, and furnished with integral bearings or ledges to engage fiat springs, and a series of flat steel springs interposed between said friction-block and said side plates or guide-castings, said friction-block having a rib or bearing engaging said springs, and said stationary friction-plate being removably secured to and connecting said side plates or guide-castings, substantially as specified.
