DRAFT-RIGGING.
Specification of Letters Patent.
vIlatented April 14, 1908.
Application area July so, 1904. serial No. 218,827.
To all whom it may concern.
Be it known that l, DWIGHT A. HITCHCOCK, residing at Detroit, in the county of Wayne and State of Michigan, a citizen of the United States, have invented certain new and useful Improvements 'in Draft-Rigging, of which the following is a specification, reference being had therein to the accompanying drawinafterdescribed, and particularly pointed out in the claims.
In the drawin s, Figure 1 is a vertical, oentral longitudine section through the draft rigging, embodying my invention. Fig. 3 is a top plan Vview thereof, with the yoke broken away. Figs. 8 and 4 are elevations of two follower members illustrating the construetion of their inter-'en ra 'ing faces. Fig. 5 is a section of one end o the draft rigging, similar to Fig. 1, showing slightly modified forni of inter-engaging faces of the rotatable and' non-rotatable members, and, Figs. 6 and are perspective views, illustrating the construction of these inter-engaging, .frictionproducing faces, shown in Fig. 5.
My draft rigging belongs to that type, in which followers have inter-locking spiral bearings, so as to produce a rotational move ment thereof, upon non-rotatable members of the followers.' l have not shown in detail the side plates and other parts of the draft rigging, as they may be of any usual construction, but have simply. indicated in Fig. 2, the usual location of the lugs or stops on the side plates.
A represents the draft bar, B the yoke.
C, C are two spiral springs concentrically arranged between the two followers, D, D. These followers D, D have formed on them, the inwardly extending sleeves-EVE, provided with inter-locking spirals F, F, so as to produce a rotational movement 'of the followers when the spring is compressed from eil hc r end, andthe return of the "followers to their normal position as the spring ex ands. The
particular manner pffforming t is spiral inter-locking feature is immaterial, as it may be done 'in any desired Way.
G is the 'head of the ,draft bar. At each end of the yoke and outside of the followers,
D, D are non-rotatable followers, ll, ll. l have shown these followers as made up oi' two parts, a and I), lhese parts engaging lugs, t. c.
in the construction shown, l have illustrati-id the parts a, as having sockets or recesses c und the parts b having corresponding lugs d engaging therewith. The parts o may be of sini lemalloable iron, while the parts'b are pre erably of steel, so as to resist the wear that it is to have/in use.
Between the follower members, D, D' and ll., i. e., between thc rotatable and non-rotin tablc members 'of the followers-I provide means to increase tht` friction. This means preferably consists of inter-migaging projections or recesses in the complementary parts. ln Figs. l, 2, 3 und -l, l' have shown this increased. friction as produced by providing on the members D, D, the annular V-shaped ribs l, which engage corresponding V-shapcd grooves J in the members b of the followers H. Suitable provision is made for the wearing oi' the parts, as illustrated in Fig. l. In Figs. 5, 6 and 7, l have shown this increased frirtional resistance as produced by a series of complementary inter-locking spiral lugs o r teeth K, K.
lt is obvious to any one familiar witlrthe construction of such draft rigging, that as the springs are compressed by the movement of the yoke in either direction, the inter-locking spiral sleeves l1), ljvill cause a rotational movement of the followers D, D and this rotational movement will produce increased frictions-l resistance to the compression of the s Jrings, due tothe rotation of these two members and this frictional resistance will bc largely increased by the engagement of the Vshaped ribs l in the V-shaped grooves J, or by the engagement of the spiral lugs or tooth K., l', shown in Figs. 5, 6 and 7.
l have shown members b as provided with inwardly projecting sleeves L, which pass through the centralaperture in the followers D, D. These sleeves form guides and snpports for the springs C.
lYhat l claim as my invention. is :m
l. ln a draft rigging, thc combination with u. yoke, followers composed of u non-rotating and a rotating member. sleeves on the nonratating members'projecting through :iperd tures in the rotating members und springs between the followers about the sleeves.
' 3. ln a draft rigging, a follower composed strains applied to the mechanism, substantially as described.
5. A strain-resisting mechanism, oomprising a rotatable conical wedge member anda coperating memberl frictionally en 20 gaged thereby, said wedge member being ro tatable in 'a direction at ri ht angles to its axis, substantially as descri ed.
In testimony whereof I aflix my signature in presence of two witnesses.
