FHIGTION DRAFT-RIGGING FOR RAILWAY-CARS.
SPECIFICATION forming part of Letters Patent No. 716,416, dated December 23, 1902.
Application filed October 27, 1902. Serial No. 128,848. (No model.)
T 610% whom it may concern:
Be it known. that I, JOHN J. HENNESSEY, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of lrVisconsin, have invented a new and useful Improvement in Friction Draft-Rigging for Railway-Cars, of which the following is a specification.
My invention relates to friction draft-rigging for railway-cars.
The object of my invention is to provide a friction draft-rigging of a simple, strong, efficient, and durable construction, in which the transversely-acting spring and double-incline friction-block may be located beneath the draft-iron and act against its lower side and which may be cheaply manufactured and readily applied to or removed from the car and which will operate to properly and efficiently cushion both light and heavy strains or blows.
My invention consists in the means herein shown and described by which I accomplish this result-that is to say, it consists, in connection with a draw-bar and draft-iron or extension in line therewith and having doubleincline friction-faces on its lower side, a stationary friction-plate in sliding engagement with the upper horizontal face of the draftiron, and a transversely-movable frictionblock below the draft-iron acted upon by a transversely-arranged spring and having double-incline friction-faces, of a pair of side plates or stop-castings secured to the drafttimbers or center sills of the car and provided each with a recess or socket in its central upper portion to receive, hold, and anchor in position one end or edge of the stationary friction-plate and with a pair of guides for the transversely-movable friction-block to reciprocate vertically in while being held from longitudinal movement and also with a pair of downwardly-projecting lugs to receive the removable spring-seat against which the lower end of the spring bears. The side plates or stop-castings are also provided with horizontally extending wings which abut against and interlock and engage each other and serve to secure the two side plates or stop castings together at their upper portions or above the draft-iron. My invention also 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 1 is a central vertical longitudinal section, on line 1 l of Fig. 2, of a friction draft-rigging embodying my invention. Fig. 2 is a plan view. Fig. 3 is a cross-section on line 3 3 of Fig. 4. Fig. d is a detail perspective view of the removable spring-seat. Fig. 5 is a detail perspective view of one of the side plates or stopcastings. Fig. 6 is a perspective view of the stationary friction-plate, and Fig. 7 is a perspective view of the draft-iron.
In the drawings like letters of reference indicate like parts in all the figures.
In said drawings, A represents the drafttimbers; A, the center sills; A the cross-sill; A the buifer-block; A the buffer-plate, and A the carry-iron. B is the draw-bar of the coupler B, these parts being of any suitable construction.
D is the sliding friction draw-bar extension or draft-iron, the same being directly in line with the draw-bar and connected thereto by a clip or yoke b, passing through an eye d in the draw-bar extension or draft-iron.
F F are a pair of side plates or stop-castings fitting between the draft-timbers and securely attached thereto by bolts f. Each of the stop-castings F is provided at its central upper portion with a recess or socket f to receive the end g of the stationary frictionplate G, so as to securely hold and anchor the same in position above the longitudinallymovable draft-iron D, and in sliding frictional engagement with the straight friction upper face 61 of the draft-iron and in the central line of draft. Each of the stop-castings F is also furnished with transverse or upright guides or flanges f to guide and hold longitudinally in position the transverselymovable friction -block H. The guides or flanges f are extended at their lower ends to form downward ly-projecting lugs f to receive, support, and anchor imposition the removable spring seat or barrel K,against which the lower end of the transverselyacting spring K bears. Both of the stop-castings F are also provided or preferably provided on their inner faces with horizontal strengthening ribs or flanges f and vertical ribs or flanges f the latter forming guide-faces for the transversely-movable friction-block H. Each of the side plates or stop-castings F is also provided with a horizontally-projecting Wingf", having interlocking or interengaging notches or tongues f andf and which abutting or interlocking Wings are secured together by bolts f so as to give additional strength to the structure as a whole.
The draft-iron D has on its lower side double-incline friction-faces d d, and the transversely movable frictionblock H has corresponding double-incline friction-faces h h, which bear against the double-incline friction-faces on the draft-iron when the draftiron moves longitudinally under either pulling or buffing strains. Bridging the doubleincline frictionfaces d d on the draft-iron there is an integral central longitudinal web d to strengthen the draft-iron and which fits in a correspondinglongitudinal groove or slot h in the transversely-movable frictionblock. The friction-block H is also provided with an integral downwardly projecting flange or cup h to receive and guide the spring K. To prevent any tendency of the draft-iron to tilt up or down on the doubleincline friction-block H as a pivot, projecting guides or flanges K for supporting or guiding the draft-iron may be provided on the removable spring seat or barrel K, especially in cases where, as illustrated in the drawings, the draft-iron is provided with only .a single pair of incline friction-faces and with a single transversely-movable friction block and spring.
To remove the draft-iron and transverselymovable friction block and spring, all thatis required is to take out the cotter-bolts K when the removable spring-seat K will drop down, and thus permit the withdrawal of the spring, friction-block, and draft-iron. My improved friction draft-rigging may be thus very quickly and conveniently removed from the car and replaced.
The draft-iron D has stop-shoulders d d",
which engage corresponding shoulders f f on the side plates or stop-castings to limit the longitudinal movement of the draft-iron and draw-bar.

In a friction draft-rigging for railwaycars, the combination with a draw-bar, of a draft-iron in line therewith and having douhie-incline friction-faces on its lower side, a stationary friction-plate above and in line with thedraw-bar and in sliding frictional engagement with the upper side of the draft- -iron, a transversely-movable friction-block below the draft-iron and having double-incline friction-faces engaging the incline friction-faces on the draft-iron, a transverselyarranged spring acting against said frictionblock, and a pair of side plates or stop-castings having each a recess or socket at its upper portion to receive and anchor one end or edge of said stationaryfriction-plate, and provided with upright guides or flanges to guide and hold in longitudinal position the transversely-movable friction-block, substantially as specified.
