YOKE FOR DRAFT-GEAR.

specification of Letters Patent.

Patented Oct. 28, 1913.

'. tcrlockinglyengage with the head of the draw bar of a coupler.

. A further object of the invention is to provide. a yoke with which the draw bar may be connected by merely inserting the head of the draw bar transversely through the side oil the. yoke, eliicient means being provided to lock the head of the draw bar in place which means may be easily positioned and easily removed.

An additional object of the invention is to provide a yoke for a draft gear, which will be composed of a minimum number of parts sov constructed and arranged that when the yoke and draw bar are in operative position upon a railway car the members of the yoke will be held in place by the parts connecting the yoke to the car end holding the yoke inplace, obviating thereby the necessity of providing auxiliary fastening means or of permanently securing the draw bar and yoke together and materially reducing the necessary weight and cost of the yoke.

Uther objects and advantages of the invention will be apparent, as itis better understood, from the following description when considered in connection with the accompanying drawing illustrating preferred embodiments thereof.

On the drawing Figure 1 is aside elevatic-n of a yoke embodying our invention and a portion oi a draw bar connected thereto;

Fig. 2 is a transverse sectional view taken substantially on the line 2-2 of Fig. 1. Fig. 3 is a perspective View of one form of the removable sliding side wall forming a portion of the yoke; Fig. 1 is a partial perspective view showing a. 'ybke in which are incorporated two removable side walls; Fig. 5

is a transverse section of a somewhat diderent term of yokeembodying our invention; and 1 ig. 6 is a partial plan view of the yoke shown in Fig. 5. I

l'teterrin to the draqliimgjfiefereuuo char actor .11 in rates draw bar ot the type or;

,tially to the The body portion of the yoke is composed I of a pair of parallelly disposed arms 14: terminatine; at their forw'ardends in inwardly disposed lugs or shoulders 15 properly shaped to engage behind the head 16 of the draw bar 11. The arms 14 are spaced apart beyond the lu s 15, a distance equal substanheight of the head 16 of the draw bar and are connected together at their rear ends as at 17 togive the yoke the customary U-shape form. The entire body portion of the yoke is preferably of rigid inflexible metal.

In Figs. 1, 2 and 3 the yoke is shown as provided with a fixed side wall 18 at one side and a sliding removable wall 19 at the other. The wall 18 is preferably made integral with the arms 14 and extends from the lugs 15 rearwardly coincident with the head 16 of the draw bar. The sliding wall 19 in the embodiment shown in this figure is com- ,posed of a flat portion 21 and inwardly err tending lips 22 spaced from the main portion 21. In the body portion of the yoke a pair of grooves 23 are provided, one upon each oft-he outer surfaces of the two arms 14. in which are adapted to seat the lips 22 of this sliding wall. These grooves are closed at their forward ends at 24 to limit the forward'movement of the wall. The grooves 23 are spaced inwardly from the adjacentedge of the body portion of the yoke, a distance equal substantially to the distance between the lips 22 and the main body portion 21 of the sliding wall. This arrangement provides a rib 25 between each lip 22 and the main portion 21, which lips prevent lateral movement of the sliding wall with respect to the body portionof the yoke.

In Fig. 1 a yoke isshown which is pro- .vided with two sliding walls 19' instead of merely the one shown in Figs. 1 to 3. It is not believed that further description is nec essary of this figure, as thewalls 19' and the .hh'dy portion oi the yoke are idei tical with that already described. the groove 23 being duplicated to permit the use of two sliding walls as shown. The yoke shown in Fig. 4: may be made by rolling or forging a strip ct thick sheet steel or iron utter grooving it We disclose a modified form of our invention in Figs. 5 and 6, the slidi removable wall 26 being located between t e arms 27 which except as immediately hereinafter de-' scribed are identical with the arms 14 of the earlier embodiment and are connected at one side with a fixed preferably integral wall 28like the fixed integral wall 18. In this embodiment bosses 29 are formed alon the edges of the arms between which the wa l 26 is positioned and these bosses and the forward ends of the arms extend outwardly beyond the rear portions of the arms as shown in Fig.6. In these outwardl extending portions of the arms and int e bosses are provided grooves 32 of appropriate shape to receive the top and bottom edges of t a sliding wall 26. In the present instance these edges and the grooves are offset at 33 and are extended inwardly at 34 to form an interlocking connection between the sliding wall 26 and the body portion of the yoke, which will prevent spreading of the-arms at this side of the yoke and also outward movement of the sliding wall with respect to the body portion of the yoke as will be readily apparent from'viewing Fig. 5.

When either embodiment is employed, the

.head 13 of the draw bar is inserted sidewisebetween the arms 14 of thebody portion of the yoke behind the lugs or shoulders 15 and is moved transversely of the (yoke into position. After the head of the raw bar has been positioned in this manner the.

sliding wall is moved to close the space between the arms and thus retain the head of the draw bar in operative engagement with the yoke. '.When the earlier embodiment or that shown in Figs. 1 to 4 is employed the 1s inserted between the arms 14. When the sliding plate is slipped over the rear end of the yoke with thelips 22 in engagement with the grooves 23 and is slid forwardly,

until these lips engage the closed ends 24:.

of-the grooves. If two sliding wallsare used as shown in Fig. 4, one is preferably positioned before the head ".i the draw bar embodiment shown in Figs. 5 and 6 is employed the sliding wall 26 is merely inserted tween'the outwardly extending portions 31 and slid into the position shown in Fig.

6, oruntil its forward movement is'stopped by the closed ends 35 of the ooves 32.

When the draw bar and siding wall or walls are in position the yoke and draw bar are ready to be operatel positioned in the draft gear-pf the car. When so positioned the sliding wall or walls are prevented from moving rearwardly by the follower plates and springs (not shown) which are ordinarily disposed through the yoke.

It will be apparent that we have provided a yoke for a draft gear, which may be operatively engaged with adraw bar without the use of the rivets, bolts or. keys which as is well known to those familiar with the art have been heretofore employed in connection with devices of this character enablin us thereby to provide a'yoke for a drat gear composed of a minimum numberof partsand of minimum weight. It will be obvious also that these parts are of simple construction and that they may be oh ly giagufactured and easily and quickly It is thought that the'invention and many of its advantages will be understood from the foregoing, without further description and it will be apparent that various changes may he made in the form and construction of the parts without departing from the spirit and scope of the invention or sacrificing any of its material advantages, the forms herein before disclosed being merely preferred embodiments thereof.
