FRIOTIO N DRAFT- RIGGING FOR RAILWAY-CARS.

SPECIFICATION f I- ming part of Letters'Patent No. 760,824, dated May 24, 1904. Application filed February-18, 1904. Serial F0. 194,209. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK B. TOWN- 'SEND, 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-Rigging for Railway-Cars,- of which the following is a specification. I 1

My invention relates to improvements in friction draft-rigging for railway-cars.

My invention consists, in connection with a draw-bar and draw-bar extension or draft iron in line therewith, having a straight friction: face on one side and double-incline frictionfaces oppositely disposed on its opposite or lower side, of a transversely or vertically rnovable friction-block having double-incline friction -faces engaging the double-incline friction-faces on the draft-iron, a transversely-arranged spring acting against said transverselymovable'friction-block, a pair ofguide-plates to receive and hold in position a friction-plate having a straight friction-face frictionally engaging the straight friction-surface of the draft-iron and furnished also with upright shoulders or guides to receive, guide, and hold longitudinally in position the transverselymovable friction-block, and a car-sill extension or housinghaving two integral limbs or members furnished with sockets to receive the ends of the car-sills and provided with shouldered recesses to receive and hold in position said guide-plates in which the transverselymovable friction-block works up and down,

and a spring seat or cup having an integral horizontal plate rigidly connected to and sup ported by the two limbs or members of the sill extension or housing, which limbs or members said plate itself connects and braces.

My invention further consists in the novel construction of parts and'devices and in the novel combinations of parts and devices herein shown or described. I

In the accompanying drawings, forming a part of this specification, Figure 1 is a central vertical section of a friction draft-rigging embodying my invention, the section being taken 511" line 1 1 of Fig. 2. Fig. 2 is a plan View,

friction-block.

In the drawings, A A represent longitudinal sills of the car; A, the cross-sill; A ,'the

buffer-block; A the buffer-plate, and A the carry-iron. I

B is the coupler, B the draw-bar, and B the draw-bar extension or draft-iron, the same having-a socket or shouldered end B to receive I the head or shouldered end B of the draw-bar and to which it is secured by bolts or rivetsB The friction-block D has beveled corners or corner-faces d, which engage the guide shoulders or flanges f of the stationary guideplates-F F, which guide the transversely-movable friction-block and hold it'from longitudinal movement with the draw-bar while permitting it to move transversely or vertically in respect thereto. The transverselymovable friction-block D is also furnished with a hollow extension rim or flange (Z at its lower end to receive and guide and hold in place the upper end of the transversely arranged and acting spring E, which bears against the lower end of the friction-block. The transverselymovable friction-block D is also provided with a longitudinal slot d to receive the vertical web Z2 which bridgesv the inclined frictionfaces 6 b and strengthens the draft-iron.

G is the spring seat or cup, against which the lower end of the spring bears, the same being also furnished with a guide portion G, which fits, receives, and guides the lower end or portion of the side casting or guide-plate V extend through the housing and both sills A A,

the housing H having an integral connecting thimble or sleeve H through Which the bolts extend. The sill-extension casting or housing H is further connected to the sills A A by vertical bolts 7& and to the front sill A and the buffer-block A by vertical bolts 7L Longitudinaltie-rods H also additionally anchor the sill-extension casting or housing H to the car-framework, the housing H having integral shoulders or brackets H to receive the tie-rod H The sill extension casting or housing H is provided With two recesses if, each having shoulders h b to receive the upright flanges or shoulders f of the guideplates F, which are thus held rigidly and firmly in position. The guide-plates F have overlapping flanges f at their meeting edges connected together by rivets The guideplates F F also have shoulders ff to form a seat for, embrace, and hold in position the stationary friction-plate C. The guide-plates F are held in place by the removable spring seat or cup G, upon the horizontal plate G of which the guide-plates F F rest. It will thus be understood that by simply removing the spring seat or cup G the spring, transversely-movable friction-block, draw bar, and the Whole draft-rigging, including the guideplates F F, may be removed When desired for repair or replacement, While at the same time the draft-rigging as a Whole,by reason of its cooperative action With the sill-extension easting or housing and its anchorage thereto to the interposed guide-plates F F, is made extremely safe, strong, efficient, and durable.

In operation under either pulling or buifing strains the draft-iron moves longitudinally With the draw-bar to which it is attached and by reason of its inclines engaging the corresponding inclines on the transversely-movable friction-block causes the friction-block to move transversely and compress the transversely-acting spring, and thus cushion the draw-bar by the frictional resistance due to the movement of the friction-surface of the draw-bar in respect to the stationary frictionplate. The friction of the inclined surfaces on the draw-bar againstthe corresponding inclines on the transversely-movable frictionbloek also increases the-resistance.
