i REVOVHLVING SWITCH-STAND FOR RAILROADS.
SPECIFICATIONforming part of Letters Patent No. 276,552, dated May 1, 18183.
Application filed December l1, 1882.
To all whom it may concern:
Beit known that we, EDWARD J. BEARD and HOWARD V. HINGKLDY, both citizens of the United States, residing at the city of Topeka, in the county of Shawnee and State of Kansas, have invented a new and useful Improvement in Revolving Switch-Stands for Railroads, the same being an improvement upon our` Patent No. 269,506, December 26, 1882, of which the following is a specification. Our invention relates to improvements in the construction of revolving switch-stands, so as to expedite the manipulation of the switch and simplify the locking and unlocking of the working-lever by dispensing with the customary auxiliary pin, as well as to couple the railconnecting rod directly with the switch-'crank without the customary nuts, split keys, or other loose parts. We attain these ends by the mechanism illustrated in the accompanying drawings, in which-a Figure l is a side elevation of the top of the switch-stand, showing our improved locking device. Fig. 2 is a plan of this same portion of the switch. Fig. 3 is a partial plan of the lower portion of the switch-stand, showing our improved union of the rail-connecting rod with the crank of the revolving shaft. Fig. @tis a vertical section in `the line X Y of the portion of the switch-stand shown in Fig. 3. Fig. 5 is a frontelevation, ofthe switch-stand complete in Working order.4 Fig. 6 is a front view of the end of the shoulder-section of the manipulating-lever with the hand-section and padlock removed.
. Similar letters refer to similar parts throughout the several views.
The shoulder-section A of the manipulating- V lever is slotted at H for about one-half of its length. The bifurcations e and f being connected at their ends by the continuous union casting E F, provided with the additional slot G. The hand-section C of the manipulatingl section Gis directly over the slot L, correspond- (No model.)
l ing to that position, and is then dropped into 1 itautomatically, assuming a'vertical position, while the lug I passes and projects through the slot G sufficiently far to receive the hasp ofthe padlock B, so dispensing with the auxlever is now held securely at this point in the slot L, preventing any horizontal movement in either direction. rBhe eye P in the connecting-rod M is of the same diameter as the lower portion of' the shaft-crank N, and the opening through the rim at Q is made to allow the horizontal portion of the crank R to pass readily through it. Thelower end, S, of the shaft N is upset, forming a seat for the connecting-rod M. so dispensing with the nut, nut-lock, and thread in common use at this point. To remove the connecting-rod M from the crank, it is revolved on N for one hundred and eighty degrees, as is to be seen in Fig. 3, bringing the opening Q directly under the horizontal portion R of the crank, when by lifting the rod it is' readily disconnected from the crank and shaft. The connecting-rod M is' so united to the shaft K that when the switch is set in the central position the opening Q in the rim of the eye P of the connecting-rod will be on the opposite side of the vertical portion' N of the crank to that from which the horizontal portionR extends to the main vertical portion of the shaft K. The other two positions bring this slot Q ninety degrees either way from the center position, -so that in no casein actual operation is the slot Q under the horizontal shank-lt, permitting the removal of the connecting-rod M, while the diameter of the depending portionf N, being in excess of the breadth of the slot Q, prevents removal of M at all times in a horizontal direction. The axis of the connecting-rod M intersects the center of the eye l?, thus enabling the connecting-rod to be used on either a right or let'thand switch by using the rod with that side up which will bring the opening Q in the rim of the eye P in the proper position, as hereinbefore described.
Having described our invention, whatwe desire to claim and secureV by Letters Patent 1s- 1'. The combination, in a revolving switchstand, ofthe shoulder-section A of the manipulating-lever, having the slot H, bifurcations iliary pin commonly used. The manipulating-` e andf, and union E F, slotted at G, with the the rail-connecting rod M, the rim of the eye 1o hand-section G, having the lug l, perforated P being;` slotted at Q, all constructed, combythe eye J for the hasp of the padlock B, `bined, and operating as and for the purpose and jointed at O with the said shoulder-seehereinbefore set forth.
