'DRAFT AND BUFFING RIGGING FR RAILWAY-CARS.
No. 880,516. l
To all whom it 'may concern.'
Be it known that I, RICHARD D. GALLA- GHER, Jr., a citizen of the United States, residing in New York cit in the county of ew York, have invented certain new and useful Improvements in Draft and Buffng 'Rig ing for Railway- Cars; and I do hereby dec are the following to be a full, clear, .and exact description of the same, reference being hadto the accoml an in drawings, form' a art of this Epecyiction, and to the illgres diid letters of reference marked thereon.
The object of this invention is to provide a draft and buffing rigging for railway carswhich will offer an effective yielding frictional resistance to draft and buiing strains and have a capacity for radialor horizontal angular movement about a center located some distance from the cou'pler heads and preferably coincident with the king in or center about which the trucks turn in t eir horizontal plane.
A further object of the invention is to provide a draft and bufiin rigging requiring no bolts or keys for attac the same tothe car sills.
i The invention consists primarily in mounting the friction and yielding resistance members so as to move in unison'angularly in a horizontal plane about the center of oscillavtion of' the draft rigging and to maintainl their alinement for resisting dra'ft and buiing riggling when in any position of adjustment wit relation to sai center whereby the maximum efficiency, is preservedat all angles and lateral strains in the rigging itself prevented.
The, invention further consists in an angularly mov-able draft and buffing rigging embodying friction and yielding strain resisting elements mounted in the .rigging intermediate the center of angular movement and d'raw bar or coupler head and finally the invention 'consists in' certain novel details of construc- .tion and combinations 'and arrangements of parts all as will be hereinafter described and pointed out particularly in the appended claims. l
Referring to the accom anying drawings-- Figure 1 is a toppla'n 'an 'half sectional view showing a portion of the sills lof a car7 a portion 'of the body bolster and a draft rigging embodying the present improvements. Fig. 2 is a central longitudinal section'of the Vparts shown in Fig. `1" with portions in elevation.'
Specification of Letters Patent.
Application filed October 1. 1906. vSerial No. 336,975. l
Patented March 3, 1908.
Fig. 3 is a side elevation of the parts shown in Fig. 1. Fig. 4 is a front elevation of the draft ri ging with the draw bar and coupler remove and with the sills in section. Fig. 5 is a front elevation of the central portion of the body bolster with the saddle casting for supporting the same. Fig. 6 is a top lan, one-half in section, of a rigging .embo ying'v a-modiied arrangement of centering devices. Fig. 7 is a vertica section of the arrangement shown in Fig. 6 omitting the friction elements and springs.
Like letters of reference in the several iigiires indicate the same parts.
In the accom anying drawings, the sills A, buffer beam E, and other usual parts of the framingof the car illustrated, are shown in outline with a view to demonstrating more clearly the a plication of the inechanism forming the sufiject matter of the present invention to a car structure. It will be understood, however, that the invention is applicable in connection with any of the usual or preferred forms of car frame particularly as 1t is the intention to so construct the draft `and bufiing mechanism that it may be applied to a car as an independent and separate element re uiringpracticallyno modification, cutting or oring of the usual framework.
The body bolster is indicated in the accompanying drawings by the letter C, and Where' designed particularly for the a plication of the present invention it is pre erably of a web and ange construction capable of being bolted firmly to the under side of the car sills and at its center provided 4with'a king pin socket of somewhat enlarged diameter'for the reception of a relatively heavy thimble C surrounding the king pin C2 so as to form a heavy center well calculated to withstand the bufling and draft strains to which the structure may be subjected. To prevent any possible tilting or rolling ofthe ody bolster due to the increased strains to which it may be subjected in resistin draft and bufling strains, and particularlyy uiting strains which are more often in the nature o a heavy shock, the said body bolster is 'connected at a point or points forward ofthe king pin with a saddlecasting D, the arms d of Whichfproect over the center sills of the car as best s own in Fig. 5, and the central depressed portion of which is connected with the front of the body bolster by one or more heavy bolts d.
Pivotally mounted in the body bolster and forwardly extending member which may be,
convenientlytermeda yoke E the rearportion of which, immediately forward of the A i versely movable wedge blocks coo ing body bolster, is formed for seating the rear follower F and the forward portion of which is lin the form of a loop adapted to contain the springs G and to forni a Vseat for the front follower F yoke is provided with shoulders E and bridges'E2 Fig. l against which a friction boxr H is adapted to seat and whereby the forward movement of s aid friction box is prevented although sufficient play is permitted said box for a limited rearward movement in the yoke for a purpose to be hereinafter pointed out.
Surroundingr the forward portion of the yoke is a housing or coupler extension I preferably formed in halves with the division in a horizontal plane and the two halves connected by bolts i. AThis housing or coupler extension is adapted at its forward end for connection with the rear end of the coupler shank or draw bar K, such connection preferably being a rigid connection and to this end the two halves of the housing or coupler extension may, at their forward ends, be suitably formed for the reception between them of the coupler shank of any-of the well known or staiidardcouplers now in use. To
connect the parts it is only necessary to sepa-l rate the two halves of the housing, insert the coupler shank and again bolt the two halves together, if desired, the usual bolt connections being also made between the coupler shank and housing-in manner similar to the usual connections between such Shanks and the ordinary strap which ,incloses the spring or other yielding strain resisting parts.
The housing or coupler extension telescopes with the yoke, but isprovided with shoulders or abutinents for cooperating with the two followers and friction box, thus the shoulders I cooperate with the forward fol* lower when the. housing is moved rearwardly and at the same time the .shoulders I2 oooperate with the friction box, said front follower and friction box being as a consequence moved rearwardly in unison with the housvOn forward movement with relation to the yoke, the shoulders I3 of the housing coperaterwith the rear follower and as a consequence said follower is advanced in unison with the housing while the friction box and forwardfollower are held against suchA movement b the yoke las heretofore explained.
The inclined friction faces h with which transrate and the latter in turn cooperate witi the rear follower F and a central wedge block or sup pleinental follower M yieldingly held toward the rear by the springs G which springs G are thus confined between the said central wedge block'M and the forward -follower F. The
At an'interniediate point saidl ictionbox is provided with internal` springs may be twin or'tandem springs or both twin and tandem springs in accordance 'with well known practice in friction draft rigging. -As shown, they are nested twin springs in tandem' with a separator or' evener 70 P ate O held between them. r The forward portion of the rigging may be supported on the usual carry irons such as indicated at P and in order to center. the
rigging or bring it back to the center line of the car after angular deflection, suitable springs may be employed between the rigging and some fixed portion ofthe car "body, As shown in Figs.l 6 and7 inwardly movable thiinbles or loops Q are mounted in the housthini'bles or loops and with a tendency to R5 push the same outwardly to their limit. With this arrangement movement of the draft rigging angularly in either direction will force one of the thinibles or loops inwardly while the other thiinble or loop will move bodily with the draft rigging thereby compressing the spring and upon release of the draft rigging the spring will at once assert itself and return the parts to ynormal centralposition. In the arrangement shown in Figs. 1 to 5 inclusive, the housing is extended` on each side to form sockets R for the forward ends of springs R whose rear ends are confined in sockets R2 in the body bolster. Said springs R bein located on opposite sides of the,
center a out which the draft rigging moves angularly, will return said rigging to normal central. position after angular deflection and in addition, willsupplement the yielding resistance of the main springs to buiiiiig strain.
In operation it will be understood that the parts composing the draft rigging proper movean ularly as a unit. In resisting draft strains, t ie rear follower F is moved forward and as the friction box is held against such movement, the wedge blocks L are moved transversely thereb wedge block or suppfeniental follower againstthe tension of the main springs G and adding to the resistance of said main springs the friction and wedging action of the friction members. In resisting bufling strains, ithe forward follower and friction box are moved rearwardly, while the wedge blocks L being held against such rearward movement by the rear follower, are moved transversely throughtlie coperation ofthe inclined faces and ii'i turn cooperate with the center wedge or sup plemental follower and force the same forwardly against the tension of the main springs. .In this action of the device it will be noted that the tension of the main springs.
advancing the center i is increased by reason of the fact that the kforward follower is compressing them from the front end at the same time that the center Wedge or supplemental follower is compress- 'the resistance offered by the main springs and friction members. Theemployment of friction members in draft rigging .not only tion with relation be moved by the other member; substantially` supplements the spring resistance but retards .recoil thereby preventing surging( and violent impact shocks to the rolling stoc Having thus described my invention, what I claim as new anddesire to-secure by Letters Patent is 1.
