COMBINED FRICTION AND DIRECT-ACTING SPRING DRAFT-RIGGING.
SPECIFICATION formingpart of Letters Patent No. 702,426, dated June '17, 1902.
Application filed March 24, 1902; $eria1llo. 99,787- (No model.)
To all whom it may concern:
Be it known that 1, JOHN J. HENNESSEY, a citizen of the United States, residing in Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in a Combined Frictionand Direct-Acting SpringDraft-Riggin g, of which the following is a specification.
My invention relates to friction spring draft-1'igging. a
The object of my invention is to provide a combined friction and direct-acting spring draft-rigging of a simple, strong, efficient, and durable construction in which the frictional resistance devices, as well as the direct-acting spring, shall all be between the draft-timbers or center sills and directly behind the draw-bar, and thus in the line of draft, and which will operate to properly cushion both lightand violent blows or strains in both pulling and buffing.
My invention consists in the means I employ to accomplish this result-that is to say,
it consists, in connection with the draw-bar of the coupler and the draft-timbers or center sills of the car and stationary sideplates mounted between the draft-timbers or center sills and secured thereto, of a draw-bar extension or draft-iron in line with the drawbar, having on one of its horizontal sides a straight friction-face and on its opposite side double-incline friction-faces, a stationary friction-plate in sliding frictional engagement with the straight friction-face of the draft-iron, a transversely-movable frictionblock having corresponding double-incline friction-faces, a transversely-arranged spring acting against said friction-block and centrally pressing the draft-iron against said stationary friction-plate, a longitudinally-arranged direct-acting spring in the vertical plane of the draw-bar or draft-iron and preferably above the same, a pair of followers for said spring, preferably recessed or cup-shaped to receive the ends of the spring, a guide having stops for said followers, preferably secured to or made integral with the stationary side plates, and projections on the draft-iron for engaging the followers of the longitudinal spring under both pulling and buffing strains.
It further consists in so combining the parts that the direct-acting spring is partially compressed before the friction-block and transversely-arranged spring acting thereagainst is brought into action under both pulling and buffing strains.
It further consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown or described.
In the accompanying drawings, forming a part of this specification, Figure l is a plan view of a device embodying my invention. Fig. 2 is a central vertical longitudinal section on line 2 2 of Fig. 1. Figs. 3 and 4 are cross-sections on lines 3 3 and 4 4, respectively, of Fig. 2; and Figs. 5 and 6 are detail horizontal sections on lines 5 5 and 6 6, respectively, of Fig. 2; and Figs. 7, 8, and 9 are detail perspective views of parts hereinafter described.
Like letters of reference indicate like parts in the several figures.
In said drawings, A A represent the drafttimbers, A A the center sills, A the front or cross sill, A the buffer-block, Aithe buffer-plate, and A the carry-iron, of a railway car, and B is the draw-bar of the coupler B.
D is. the sliding frictiondrawbar extension or draft-iron directly in line with the drawbar and connected thereto by a strap or clip 0 and bolts C, the strap passing through the eye 61 of the draft-iron, the head (1' of which is rounded to allow the necessary vertical play of the draw-bar. The loose fit of this connection also allows for the necessary lateral play of the draw-bar with respect to the draft-iron D. The draw-bar extension or draft-iron D has a straight friction surface or face (1 on one of its horizontal sides, preferably its lower side.
F F are the side plates, fitting between the draft-timbers or center sills and securely attached thereto by bolts f. The side plates are preferably connected together or cast in on piece.
G is a stationary friction-plate directly behind the draW-bar and in the central line of draft, the friction-face d of the draft-iron D being in sliding frictional engagement therewith. The stationary friction-plate G is removably supported on the side plates by crossbars G, having keys G It is securely stopped or anchored in position on the side plates by the inter-engaging shoulders or projections g g g and ff on the plate G and side plates F, respectively. The draft-iron D on its opposite side from the stationary friction-plate G has double-incline friction-faces (1 d II is a transversely-movable friction-block having double-incline friction-faces 72 h, corresponding to and bearing against the doubleincline friction-faces d on the draft-iron- The friction-block H is rectangular in shape and has guide projections 7L2 71 which fit in corresponding vertical guidewaysf in the side plates F, formed by the vertical extension of the shoulders f f. To strengthen the draftiron, it is furnished witha central longitudinal web (1 fitting in acorresponding groove or channel it in the friction-block II. The friction-block II also has a projecting rim or seat 71 to receive and inclose the end of the transversely-arranged spring K, which acts against the friction-block H, and thus serves to centrally press the draft-iron D against the stationary friction-plate G, all being arranged directly behind the draw-bar and in the line of draft. Inside the main spring K a smaller supplemental spring 7a is arranged.
M is the seat, support, or abutment for the upper end of the springs K 70, the same being preferably connected to or cast integral with the side plates F F. The draft-iron D is also provided with shoulders or stops 6 d to engage corresponding shoulders or stops f on the stationary frame or side plates F F.
Nisalongitudinally-arrangeddirect-acting spring, the same being compressed under both pulling and buffing strains by a pair of longitudinally-movable followers P P, preferably cup-shaped or furnished with seats or recesses 19 to receive, guide, and support the ends of the spring N. These followers reciprocate longitudinally in a guide R, the same being preferably connected to or cast integral with the side plates or frame F F. The stationary guide R for the followers P of the longitudinally-arranged direct-acting spring N extends parallel to the draw-bar in the central line of draft, the same being directly above the drawbar or its extension D. The followers P P are operated to compress the spring N by wings or projections D D on the draft-iron D, the same being preferably cast integral therewith and provided with shoulders al which engage the ends p of the followers P P, the guide R for the followers having openings or slots for the ends of the followers to project through, as will be readily understood from Figs. 4: and 5 and 1 and 2.
The double inclines d d on the draft-iron are preferably more separated than the corresponding double inclines h h on the transversely-movable friction-block F, so that the direct-acting longitudinal spring N may be partially compressed in either pulling or buifing before the friction-block and transverselyarranged spring come into action. The longitudinal direct-actin g spring thus softly and properly cushions the light blows or strains of switching or ordinary usage, while the transversely-arranged spring and friction-surfaces come subsequently into action to cushion and withstand the heavier shocks or blows.
In the drawings I have illustrated my invention as being applied to a car having both draft-timbers and center sills. It is, however, equally applicable for use upon cars where the draft-timbers are omitted or metal center sills are employed, the center sills in such case being somewhat deeper.
The front follower P abuts against a movable key S,inserted through the guide R. The rear follower abuts against the rear end of the guide R.
