' DRAFT RIGGING.
A Application tiled January 10, 1925. Serial No. 1,657.
The invention relates to `draft rigging for railway cars and has particular reference to means for connecting the lcoupler shank f with the yoke.
T heprincipal object of the invention, generally stated, is to provide means for pivotally connecting a coupler and yoke, said means comprising an upright pin orv key, the coupler and yoke being provided with slots so disposed and arranged that accidental disengagement of the coupler connecting means while the lparts are in serinvention.
vice is impossible.
The object of the invention, more specif` ically stated, is the provision of a draft riggin having a yoke provided in its arms wit elongated slots adapted to register with similar slots in the coupler shank to permit the insertion of a pin or'key designed to be subsequently4 rotated to bring .retaining gibs thereon into engagement with the arms of the yoke, the slot arrangement being such that the expansion of. the draft gear or cushion device will hold thecoupler shank in such relation to the yoke that portions of the slots will be out of registration, the opposite ends of the respective slots engaging against the pin or key. n
Another object of the invention is to rovide a structure of this character in w ich means is provided engaging one end of the pin or key for preventlng rotation thereof put of its normal position so that the gibs cannot accidently come into registration with the slots.` Y'
' A further'object of the invention isto provide a drat rigging in which the coupler shank and yoke are slotted for the accommodation of a pin or key which rovides of the oke slots and coupler vshank slot be,- ing suc as to permit the necessar and proper relative movement of the coup er with re-- spect to the yoke, the provision of the slot in the coupler shank making it possible to have short slots in the vyoke arms so that the yoke arms may be made comparatively narrow at points spaced somewhat back from the ends, thus permitting the utilization of front stops for the draft gear of greater inward proping down out of place.
likelihood of breakage or distort-ion at thispoint.
Another object of the invention is to pro- In the drawings:
vcase with certain types of connections.
Figure 1 is a view partl in plan and partly in horizontal section illustrating the Figure 2 is a view made partly in section along the,line 2-2 of Figure 1, certain parts being in elevation. Y Figure 3 is a cross section on the line 3-3 of Figure 2, k Fig. Lis a bottom plan View of the draft n ey.
Referring more particularly to the drawings, I have illustrated a portion -of a draft rigging including center sllls 1 carrying the end sill 2 beyond which is the striking casting 3. Suitably secured between the center sills is the backstop 4 against which engages the rear end of a yoke 5 here shown as vertically arranged, within which is located any suitable or preferred draft gear or cushion device, indicated at (i, cooperating with front stops 7 secured to the center sills. In the present instance I have shown a yoke filler 8 within the inner or rear end of the yoke and fitting between. it and the draft gear, the filler having means, such as the extensions 9, for preventing it from drop- The forward ends ofthe arms of the yoke are formed with elongated slotsflO. the pivotal connection, thecombine lengths f The numeral 11 designates the coupler shank which engages against the forward end of the draft gear 6 and which is formed with an, elongated slot 12 which may be of the same size and shape as the slots l() in the yoke arms and adapted to register there,
means, which in the present instance, I have shown as a vertical pin or key 14. This key or pin is represented as of cylindrical formation and provided at its ends with retaining means herein disclosed as consisting of gibs 15 capable of passing through the registering slots 10 and 12 when the pin or key is properly turned, but ordinarily adapted to engage against the upper and lower surfaces with to permit insertion of the connecting of the upper and lower yoke arms, respectively, for reventing longitudinal movement of the key when in place.
It is desirable that means be provided for positively preventing rotation of the key or pin while the car is in service and this feature may conveniently be carried out by providing a carry iron 16 secured beneath the center sills in such position as to extend across the lower end of pin or key, the carry iron having guide means such as a groove or way 17 therein slidably receiving an extension 19 of angular shape on the lower end of the key or pin.
Assembling of the partsl can be effected only when the draft rigging is out of the car as this is the only time when the slots 10 and 12 can be brought into registration. The key or pin is inserted while in such position that the gibs thereon may pass through the slots, after which the key is given a quarter turn to bring the gibs in transverse relation to the slots. The draft gear or cushioning unit is then inserted and the parts raised to proper assembled position between the car sills. When the carry iron is applied so that the pin engages therewith, the co-action of the extension 19 with the groove or Way will prevent subsequent rotation of the Vkey or pin. When in normal `position the cushioningI unit 'will maintain the major portion of the slots 10 and 12 out of registration, the outer ends of the slots 10 and the inner end of the slot 12 engaging against the pin orkey so that even though no means were provided for reventing rotation thereof the key woul still be prevented from displacement as the gibs wouldl the yoke alone formed with slots to permitl the necessar relative movement of the coupler and yo e, the lengthof the yoke slots may be greatly reduced, therebyy making it possible to form the yoke comparatively narrow at a point somewhat back from the forward end instead of wide as would be necessary to give proper strength at the sides of long slots. This feature of comparative narrowness of the yoke is of great importance inasmuch as it then' becomes possible to utilize front stops for th'edraft gear, or front follower thereof, which may extend further into the space between the center sills and thus provide an increased bearing surface for the follower or draft gear which will reduce likelihood of distortion or breakage at this point. Another distinct feature of advantage is thatin case ofbreakage of the draft connectiorr only the pin orkey arms vof the served to make all such changes in the form,
construction and arrangement of parts as will widen the eld ofV utility and increase the adaptability of the device, provided such variations and modifications constitute no departure from the salient features of the invention or the scope of the hereunto appended claims.-
