r T0 a/ZZ whom it mor/y concern:

`Be it known that LRICHARD D. GALLAGHER,

State of New York, have invented certain new and useful lmprovementsin Draft or Buffing Rigging; and I do hereby declare the i ;l following to be a full, clear, and exact descrip- 1 tion of the same, reference being had to the accompanying drawings, forming a part of `this specication, and to the figures of reference marked thereon. y This invention relates to improvements 1n r. `rigging designed to yield and take up strains i I5 of partsmoved by heavy pressure; and while the invention is well adapted for use in connection with heavy mechanism or mechanism 11 quirementsof the draft-rigging for cars, and

` operating under heavy pressure, such as ordnance, wherein the recoil must be checked, it is `particularly designedto answer the remore especially rigging of heavy rollingstock-as, forinstance, the modernsteel cars of large capacity.

`In its application to draft-rigging for cars 3 "the invention is designed to be capable of `ready application to cars of practically any type and having either steel or wood drafti timbers or framing.

To this end one of the objects of the inveni tion is to provide a structure capable of bei ing readily substituted for draft-rigging on rolling-stock now in use or applied to rollingstock in course of construction without cutting to any material extent the draft-timbers when of wood or modifying the framing when 1 of metal.

A furtherobject of the invention is to provide a structure in which the springs may be i arranged in theline of pressure and at the i 1 same time their resistance so augmented and modified thatl springs of ordinary standard y size and power may, where desired, be util- "1 `ized for the draft-rigging of rolling-stock of practically unlimited weight and without occasioning shock or oscillation of the cars in starting, stopping, or varying speed `and reprior application, Serial No. 54, 900,filed April S, 1901, and is designed to cover that form of mechanism wherein the movement of the pressure-transmitting member in either direction is converted into a reverse movement in compressing the spring, and whereby the structure may be adapted to compressv the spring by opposite movements of its confining-abutments, the resistance of the spring being augmented by the resistance due to the friction and wedging action of the members intermediate the spring and pressure-transform to the requirements of car-frames of any construction now in use or so as to be capable of application thereto without modification, but simply by varying the mode of attachment. ln the presentinstance, as in the usual forms of draftrigging, the working parts of the apparatus are supported and work between suitable supports-such, for instance, as the cheek-plates l, having suitable stops and guides 2 for the followers. The cheek-plates are simply a type of supporting mechanism, and it is obvious that any other or preferred type may be substituted. The spring 3'is mounted between followers et, the latter being carried by the cheekplates and held by the stops 2 against outward movement, but are free to move inwardly or toward each other and back to normal position.

Surrounding the followers and spring is a frame 5, corresponding to the ordinary strap, onlypreferably heavier and stronger than plates are made as nearly as possible to conthe usual strain-said frame being attached at one endV to the draw-bar 6. The frame 5 constitutes part of the pressure-transmitting member, and between it and the followers a mechanism is provided which will convert the movement of the frame in one direction to a reverse movement of the forward foladapted to be vdisplaced transversely by ineline 8 on the fra-me 5 and in turn cooperates with the incl-ine 9 on the follower 4, whereby,

the follower is displaced li'neally and in direction opposite to the direction of movement of the frame. The wedge block is guided in its transverse movement by a cross or follower plate l0, held by the supports or cheek-plates.

The mechanism is preferably du plica-ted at each end of the spring, the parts being reversely arranged, and in order that the de-I vice may be double-actin g in both directions,

so as to compress the spring from both ends,

the cross or follower plates are mounted between stops 11,- so as to be capable of an inward movement, whereby on movement of the p'ressure-transmitting member the rear `cross or follower plate will advance and carry with 1 itas a body the wedge-block and follower,

while the other cross' or follower plate will remain stationary, and the incline on the frame, acting through the wedge-block and followerv incline, will move the forward follower ba'ckt the followers having inclines on their outer wardly against the tension of the spring.

Thev mechanism operates in like-manner in either direction, and it is obvious that by changing the ang-le of the incli-nes the resistance, d-ue to friction and wedging actionl ofthe parts, may be varied to suit the conditions under which the apparatus is designed to work', and thus standard springs may be employed for all classes of work, and while with/the structure shown the spring is adapted to be compressed from both ends it is obvious that the wedging devices alone may be utilized for each movement, thereby compressing the spring from one end only.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l.` In an apparatus of the character specified, the combination of the following instrumentalities, to wit; a pressure-transmitting member,an incline moving therewith,a wedgeblock adapted to be displaced transversely by said incline, a follower cooperating with the wedge-block and adapted to be displaced thereby in a direction opposite to the direction of movement of the pressure-transmitting member and a spring for resisting the movement'of the follower, as set forth.

2. In an apparatus of the character specified, the combination of the following instrumentalities, to wit; a spring, a follower working against said spring, an incline moving with said follower, a transversely-movable wedge-block cooperating with the incline to displace the follower against the tension of thefspring, a transverse guide for the wedgeblock, a pressure-transmitting member movable in line with the line of springcompression and an incline moved by the pressuretransmitting' member and cooperating with the wedge-block to displace the same transversely; substantially as described.

8. In an apparatus of the character specified, the combination with followers,stops for holdingsaid followers against outward move- `-mentiwhile permitting them to move inwardly, `and a spring cond-ned between said followers, of an incline moving with one of said followers, a transversely-displaceablewedge-block cooperatingwith said incline,a-pressure-transmitting member and an incline moving therewith and ycooperating with the wedge-block to displace the same transversely against the tension of the spring exerted through the follower and incline moving therewith; substantially as described.v

4. In a draft-rigging the combination with 'the' 'followers having inclines on their outer sides, a spring confined between the followers and transversely-movable wedge-blocks cooperating with said inclines, of a press-uretransmitting member, inclines moving therewith and cooperating with the wedge-blocks, and guides with which the wedge-blocks cooperate in their transverse movement; substantially as described.

5. In a draft-rigging, the combination with sides, a spring confined between the followers, and transversely-movable wedge-blocks cooperating with said inclines, of a pressuretransmitting member, inclines moving therewith and cooperating with the wedge-blocks and guides formed by inwardly-'movable crossplates with which the Iwedge-'blocks cooperate in their transverse movement; substantially as described.

6. In a draft-rigging, the combinati-on with the spring, the longitudinally-movable follower against which the spring abuts, an incline on said follower, and a pressure-transmitting member movable longitudinally-or in the direction of movement of the follower and having an incline at an angle to the incline on the follower, of a transversely-movable wedge-block interposed between said inclineswhercby the longitudinal movement of said pressure-transmitting member or follower will impart an opposite movement to the other member; substantially as described.

7. In a draft-rigging, the combination with the oppositely-located followers, the springinterposed between said followers, and the inwith the wedge-blocks; substantially as described.
