ROBERT C. HYDE, OF DES MOINES, IOWA.

LOCK FOR LOCOMOTIV'E SHAKER BARS.

Application filed October 11,, 1924. Serial No. 742,969.

To all inhomit may concern:

Be it known that 1, ROBERT C. HYDE, a citizen of the United States of America, and residentof Des Moines, county of Polk, State of Iowa, have invented a certain new and useful Improvement in Looks for Locomotive Shaker Bars, of which the following is a true and eXact description, reference being had to the accompanying drawings, which form a part thereof.

My invention relates to looks for locomotive shaker bars of the general character of that described in my prior Patent 1,412,181

The object of my invena lock of the same general character but of improved and more convenient construction. Myinventio-n will be best understood as described in connection with the drawings in which it is illustrated and in which- Figure 1 is a perspective view of a loco-- motive shaker bar provided with my improved locking device, the locking device being shown in normal or looking position.

Figure 2 is a similar view of the locking device showing it in tilted relation to the shaker bar in the position it occupies when the shaker bar handle lever is being applied or being disengaged from the shaker bar, and

Figure 3 is a view showing the bar and latch as in Fig. 1. but with the handle lever applied in operative position.

A indicates the shaker bar which in my new construction is provided at its upper end with a lateral pivot supporting lug A on the base of which is formed a stop shoulder, as indicated at A B is a pivot supported on the lug A and G is the locking device which in my new construction is of generally triangular form with a lighter end C which serves as a latch to hold the handle on the bar and normally occupies the position shown in Fig. 1. The heavier end C of the latching device has a lower end C which normally rests on the shoulder A as shown in Fig. 1, and from which extends upward the side C lying normally close to the edge of the shaker bar and extending up above the lug A, as shown. From the upper end of this side of the tri angular latch the sloping surface C extends down to the narrow latching;- end C. I) in dicates the handle lever which is provided with a tapered socket as indicated at D which is adapted to slip over the tapered end of the shaker bar to the position shown in F ig. 3.

In operation, the latching device being in its normal position as shown in Fig. 1, the handle bar in being applied to the end of the shaker bar comes in contact with the sloping surface C with the effect of pressing downward and inward the latching; end C, as shown in F 2. As soon as the socket D is passed the latching device the latter returns by gravity to its normal position, effectually latching the handle lever on the end of the shaker bar, as shown in Fig. 3. \Vhen it is desired to remove the handle lever it is only necessary to press on the side C of the triangular latching; device to turn it to the position shown in Fig. 2, in which position it offers no resistance to the removal of the handle lever.

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

In combination wi h the end of a shaker bar, a latch pivoted thereon to turn in a plane parallel to the side of the bar, said latch having a generally triangular shape with a lighter end adapted to normally QX- tend beyond the edge of the bar and serve as a latch to lock the handle lever to the end of the bar, a heavier end extending upward above the opposite edge of the bar end and a sloping upper side extending; from the top of the heavy end to the latch end, and a stop shoulder on the bar extending below the pivoted latch member serving; to support the latch member in operative position and to limit the downward and inward motion of its latching end.

ROBERT C. HYDE.
