DETACHABLE HANDLE FOR SHAKER BARS.

Application filed Deceniber 12, 1925. Serial No. 75,040.

This invention relates to detachable han dles for shaker bars.

One of the objects is to provide a handle having means for easily and quickly attaching the same to the vertically-disposed shaker bars of locomotives or the like toogive the same the necessary rocking movements to shake the grate bars therein, and to automatieally lock the same in such engagement so as to avoid accidental dislodgment thereof during the jarring and jolting movements of said locomotive.

Another object is to provide a simple, strong and durable device of this character which may be applied to the shaker bar from either side, the strain of the shocks of shaking the heavy shaker bars being taken by relatively heavy castings and not byvpins, bolts, pawls or other easily-broken elements, the device being so formed as to take care of the wear incident to such heavy usage, and being readily detached from the shaker bar by simply lifting a locking member when the operation of shaking the grates is completed.

A full and complete understanding of the invention may be obtained from a consideration of the following detailed description, taken in connection with the accompanying drawing forming a part of this specification; it being understood that while the drawing shows a practical form of the invention, the

latter is not to be confined to strictconformity with the showing thereof, but may be changed or modified, so long as such change or modifications mark no material departure from the salientfeatures of the invention, as specifically pointed out in the appended claim.

In the drawing, in which similar reference characters designate corresponding parts throughout the several figures Figure l is a front elevation showing a portion of a shaker bar having the improved handle. and locking means for the same applied thereto.

Figure 2 is a vertical, longitudinal section through the same.

Figure 3 is a horizontal'section taken on the line 3-3 of Figure 1.

Figure l is a detail perspective view of the locking member.

Referring to the drawing there is shown the upper portion of an ordinary shaker bar 1 such as is inconnnon use on locomotives or the like for shaking the grate bars in the fire box, the same being usually pivoted intermediate of its length on a transverse, horizontal pivot (not shown), and having its side edg s 2 slightly tapered towards the upper end as shown. At the proper point the flat side faces of the bar l'are provided with an inwardlyextending recess 3 formed in each face and exactly opposite to each other, each recess having its rear wall 4 inclined inwardly and downwardly and the bottom wall 5 thereof formed perpendicularly to the rear wall, as clearly shown in Figure 2 of the drawing.

The detachable shaker bar handle 6,formed preferably of wrought iron or steel to withstand the wear, is somewhat wider than the upper end of the shaker bar and may be of any desired length. An integrally formed socket 7 is formed at the lower end of the handle and is located, preferably, at one side thereof, though said socket may have other relation to the said handle, and the latter is preferably tapered towards the upper end of the same to provide a convenient grip for the operator.

The socket 7 is open at the upper and lower ends, as shown, and the lower end of the handle itself constitutes the back wall of the socket, while the front wall 8 is of sufficient height to provide ample bearing on the upper end of the shaker bar 1. On the upper portion of the frontwall 8 there is provided a centrally located, integral boss or lug 9 extending part way down on the outer face of said front wall and whose outer face is inclined with relation thereto, while the upper face ofthe same slopes downwardly and out wardly to provide a shoulder 9 for a purpose to be explained.

A longitudinal, inclined channel or passageway 10 extends through the lower portion of the front wall 8 and upwardly and out-- wardly through the aforesaid boss or lug, the open, upper end of said passageway being located in the lug or ooss while the lower end of the same communicates with the interior of the socket, and the inner wall of the passageway is adapted to aline with the inner, inclinedwall l of one of the aforesaid recesses 3 formed in the shaker bar 1, when the socket is placed over the upper, tapered end of the shaker bar, it being understood that the inner side walls of the socket are tapered to accord with the taper of the shaker bar, so that the bar and the handle may be associated with the socket on one side or the other, and one or loo with the lower end of the passageway l0.

A locking member or latch 11, of a crosssectional size and shape to freely slide into the passageway, is placed into the same and is adapted to gravitate into a position with the lowerend of the same snugly fitting the adjacent recess 3, as clearly shown in Figure 2 of the drawing. The upper end of the latch 11 is provided with an integrally-formed ring 12. to provide a finger hold to raise the latch when detaching the handle from the shaker bar,- and said ring'is providedwitli a shoulder orl 'ig 13 'which normally rests upon the aforesaid shoulder 9*? of the socket and arrests further downward movement within the passageway.

The body portion of the latch isfurther provided with a vertical longitudinal slot 14,

arranged centrally thereof, said slot extending throughout the major portion of the length of the latch and being closed at its upper and lower ends. A screw 15 mounted in the front wall of the socket and in the boss 9, travei'sesthe slot 14 of the latch and prevents the accidental dislodgment of the latter from its slidable seat in the passageway. The length of the slot 14 is sufiicient to allow the latch to be elevated sufiiciently to free the lower end thereof from its engagement with the recess?) of the shaker bar and to permit the handle to be easily and quickly detached therefrom. In attaching the handle to the shaker bar it is only necessary toplace the lower end of the socket, which may have its inner lower edges tapered or rounded for the purpose, over the upper end of the shaker bar and to lower the same thereon, when the upper end of the bar will contact with the lower end of the latch, which normally projects into the socket and shove said latch up in the passageway and out of the way to allow the shaker bar to'be fully seated, when the latch will quickly gravitate again into the recess?) and automatically lock the two members together, the lug 13'at the same time resting on the shoulder 9;

From the foregoing it will be seen that a simple, cheaply-manufactured and strong and durable device has been provided for th1s purpose which willautomatlcally lock 1n position without any effort on the part of the fireman oroperator, that the tapered formation of the cont-acting parts Wlll tend to compensate for wear and eliminate lost motion,

and that by a single movement the parts may be easily and quickly. separated when the vided with an inwardly and downwardly in clined inner wall and a lower wall perpendicular thereto and constituting a shoulder, of a detachable handle having a vertically-disposed socket at the lower end there- 'of and on one side of the-same, said socket havin" ta )ered side walls to fit the shaker bar and being open at the upper and lower ends to permit saidbar to extend through thesame, the

outer wall of the socket having an outwardly extending inclined boss or lug formed thereon and provided with an mclined passageway extending through the same and communicating at its lower end with theinterior of the socket at a point opposite the recess in the shaker bar, a latch provided with a central vertical slot and slidably fitting the passageway to gravitate intothe recess to automatically lock the handle to the bar, said latch extending above the socket and formed into a lifting ring to unlock the handle from the bar and provided with a shoulder to rest on the boss, and a screw mounted in the boss and traversing the slot in the latch-to prevent removal of the same.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature. GEORGE EDWARD TAYLOR, JR.
